The relationship between children and their maternal uncles in contemporary Mosuo culture reveals a unique parenting mode in a matrilineal society. This study compared the responses of Mosuo and Han participants from questionnaires on the parent–child and maternal uncle–child relationship. More specifically, Study 1 used Inventory of Parent and Peer Attachment to assess the reactions of the two groups to the relationship between children and their mothers, fathers, and maternal uncles. The results show that while Han people display (...) a higher level of attachment toward their fathers than their maternal uncles, Mosuo people do not exhibit a significant difference in this aspect. Study 2 used a scenario-based method to compare how adults and teenagers perceive the rights and responsibilities of fathers/maternal uncles toward their children/nephews or nieces. The results show that Han adults attribute more rights and responsibilities to their own children than nephews/nieces, while their Mosuo counterparts have the reverse pattern and assign stronger responsibilities to their nephews/nieces than their own children. Both groups perceive the fathers to be the bearer of rights and responsibilities, although this perception was weaker among Mosuo. This paper concludes that in the Mosuo society, fathers have a relatively weak social role as a result of their unique matrilineal social structure. (shrink)

Why does one need creativity? On a personal level, improvisation with available resources is needed for online coping with unforeseen environmental stimuli when existing knowledge and apparent action strategies do not work. On a cultural level, the exploitation of existing cultural means and norms for the deliberate production of novel and valuable artifacts is a basis for cultural and technological development and extension of human action possibilities across various domains. It is less clear, however, how creativity develops and how exactly (...) one arrives at generating new action possibilities and producing multiple alternative action strategies using familiar objects. In this theoretical paper, we first consider existing accounts of the creative process in the Alternative Uses Task and then present an alternative interpretation, drawing on sociocultural views and an embodied cognition approach. We explore similarities between the psychological processes underlying the generation of new uses in the Alternative Uses Task and children’s pretend play. We discuss possible cognitive mechanisms and speculate how the generation of new action possibilities for common objects in pretend play can be related to adults’ ability to generate new action strategies associated with object use. Implications for creativity development in humans and embodied artificial agents are discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:74 Feminist Studies 46, no. 1. © 2020 by Feminist Studies, Inc. Jennifer L. Holland “Survivors of the Abortion Holocaust”: Children and Young Adults in the Anti-Abortion Movement During the last three decades of the twentieth century, children across the United States regularly encountered adults who both hailed them as survivors of a holocaust and pleaded with them not to perpetrate one. These adults (...) were not talking about war, at least not in a traditional sense. They were talking about legal abortion. Children and young adults often heard this pitch in school presentations like one made in the mid-1970s by a California anti-abortion group, United Parents Under God, in which pictures of aborted fetuses (whose “feet will never kick a football... run on a playground... or play hopscotch”) and their imagined lost life stories were the centerpiece. Next to pictures of aborted fetuses were pictures of two prematurely born infants of color (the only people of color in the presentation) who were supposedly in danger under Roe v. Wade. With murder hovering in the air, activists asked their teen audience, “Is someone you love next?” According to these California anti-abortion activists, young people were physically and intellectually vulnerable to pro-choice views because they inhabited “atheistic” classrooms “where evil can no longer be called ‘evil.’” “You are quite literally ‘trapped’ in a completely ‘pagan’ situation in our secular society and schools and we must reach you anyway we can,” they continued. In the so-called “pro-life” worldview, liberals were brainwashing children and young people through the media, public schools, and many other institutions. Jennifer L. Holland 75 “Women’s liberal abortion speakers,” political scientists, “who typically work for the STATE” and for whom the “ends justify the means,” and new “secular-science textbooks”—all were trying to frighten teenagers to “into killing [their] OWN OFFSPRING,” activists said. Anti-abortion women, “ordinary women... who LOVE you” according to the California presentation, sought to protect children while feminist “witches... distort [ed] God’s purposes of sexuality.”1 In order to counteract what they viewed as corruption, anti-abortion activists had to wage a counter -battle, politicizing children in order to make them innocent again. In practice, that meant bringing the abortion wars—with their attendant graphic imagery and discussions of immorality, murder, and “holocausts ”—into the haven of childhood. From the movement’s early days, anti-abortion activists waged their fight in the name of innocent young people; abortion, they said, was a genocide of children. While these activists were certainly not the only US movement to use the supposed vulnerability of children to elicit public support for their cause, they also did something different. For the anti-abortion movement, children and young adults were more than just endangered innocents; they were also potential perpetrators. Young people, it seemed, were more liberal than their elders, having allegedly been reared in and indoctrinated by liberal culture. They seemed, in short, to be a potentially pro-choice generation. Thus, adult activists spoke more to and about young people at the end of the century. Adults needed young people to speak for fetuses as “Survivors of the Abortion Holocaust,” but they also needed to convert and save America through them. The anti-abortion narrative of childhood vulnerability offered the restoration of social hierarchies as a solution to the problem of abortion. It was “women’s liberal abortion speakers” and feminist “witches” who were the sources of societal indoctrination. Pro-choice women separated sex and reproduction, thus undermining women’s role in society and changing their relationships with men. More subtly, anti-abortion 1.

This paper examines the culture, the dynamics and the financial underpinnings that determine how medical research is being conducted on children in the United States. Children have increasingly become the subject of experiments that offer them no potential direct benefit but expose them to risks of harm and pain. A wide range of such experiments will be examined, including a lethal heartburn drug test, the experimental insertion of a pacemaker, an invasive insulin infusion experiment, and a fenfluramine "violence (...) prediction" experiment. Emphasis, however, is given to psychoactive drug tests because of the inherent ethical and diagnostic problems involved in the absence of any objective, verifiable diagnostic tool. Effort is made to provide readers comprehensive reference sources to evidence-based reports about the serious risks these drugs pose for adults and children so that the reader may judge whether the benefits (if any) outweigh the risks for children. The first ethical issue raised by these experiments is: did the severity of illness in these children justify their exposure to short and long-term risks? The ethics of the experiments will be evaluated by referring to existing codes of medical research ethics-the Nuremberg Code, the Declaration of Helsinki, and the federal Code of Regulations. The thirteen cases presented will demonstrate that children are being used in ever more speculative experiments, often in the absence of a therapeutic intent, but a significant chance for causing harm and / or discomfort. Some of the experiments were designed to explore the mechanisms of pathology and pharmacological interventions, or the response of neurological brain receptors to chemical provocation ("challenge"). Others were designed to test the safety or efficacy of new drugs, even to test these drugs on healthy children who were hypothesized to be "at risk." Children and adolescents have been subjected to "forced dose titration" experiments that induced a spectrum of severe adverse effects, including insomnia, extreme restlessness, agitation, (akathisia) and self-injurious behavior. FDA reports show that suicide is a significant issue in psychotropic drug trials-in pediatric trials the problem is even greater. The paper aims to demonstrate how the enactment of the Better Pharmaceuticals for Children Act (incorporated into the Food and Drug Administration Modernization Act, FDAMA), set in motion a radical shift in public policy by providing huge financial incentives to pharmaceutical companies to test new or patented drugs in children. Federal policy shifted from one aimed at protecting children by setting limits on permissible research risks, to a policy aimed at broadening the inclusion of children as test subjects. It will be shown how the FDA and the Department of Health and Human Services lifted regulatory restrictions to permit research involving greater than minimal risk to be conducted on healthy children, claiming that all children are potentially "at risk" of a future condition. Children were in this way deprived of regulatory protections. An argument will be made that the approval of nontherapeutic, harmful experiments-such as exposure of toddlers to lead poison-under the current gate keeping system raises serious doubts about the sustainability of institutional review boards (IRBs) as protectors of human research subjects. Children, who are precluded from exercising the adult human's right to informed consent, are being exploited as commodities for commercial ends. It is the position of the author that nothing less than the enactment of a federal law mandating a radical overhaul of the current research review system, with independent checks and balances, will provide children the legal protections they need. Ten specific recommendations are offered to protect children from harmful experiments. (shrink)

Lexical alignment, a communication phenomenon where conversational partners adapt their word choices to become more similar, plays an important role in the development of language and social communication skills. While this has been studied extensively in the conversations of preschool‐aged children and their parents in Western, Educated, Industrialized, Rich, and Democratic (WEIRD) communities, research in other pediatric populations is sparse. This study makes significant expansions on the existing literature by focusing on alignment in naturalistic conversations of school‐aged children (...) from a non‐WEIRD population across multiple conversational tasks and with different types of adult partners. Typically developing children aged 5 to 8 years (n = 45) engaged in four semi‐structured conversations that differed by task (problem‐solving vs. play‐based) and by partner (parent vs. university student), resulting in a corpus of 180 conversations. Lexical alignment scores were calculated and compared to sham conversations, representing alignment occurring at the level of chance. Both children and adults coordinated their conversational utterances by re‐using or aligning each other's word choices. This alignment behavior persisted across conversational tasks and partners, although the degree of alignment was moderated by the conversational context. These findings suggest that lexical alignment is a robust phenomenon in conversations between school‐age children and adults. Furthermore, this study extends lexical alignment findings to a non‐WEIRD culture, suggesting that alignment may be a coordination strategy employed by adults and children across diverse linguistic and cultural backgrounds.

In this event-related potential study a masking technique that prevents conscious perception of words and non-words through attentional distraction was used to reveal the temporal dynamics of word processing under non-conscious and conscious conditions. In the non-conscious condition, ERP responses differed between masked words and non-words from 112 to 160 ms after stimulus-onset over posterior brain areas. The early onset of the word–non-word differences was compatible with previous studies that reported non-conscious access to orthographic information within this time period. Moreover, (...) source localisations provided evidence for automatic activation of prelexical phonological information, whereas no evidence for non-conscious semantic processing was found. When subjects were informed about the masking technique, lexical differences occurred at later time intervals, suggesting conscious access to additional word related information. These results indicate that early visual word processing does not depend entirely on attentional resources, but that non-conscious processing probably is restricted to rather lower-level linguistic information.

Recent research has demonstrated an asymmetry between the origins and endpoints of motion events, with preferential attention given to endpoints rather than beginnings of motion in both language and memory. Two experiments explore this asymmetry further and test its implications for language production and comprehension. Experiment 1 shows that both adults and 4-year-old children detect fewer within-category changes in source than goal objects when tested for memory of motion events; furthermore, these groups produce fewer references to (...) class='Hi'>source than goal objects when describing the same motion events. Experiment 2 asks whether the specificity of encoding source/goal relations differs in both spatial memory and the comprehension of novel spatial vocabulary. Results show that endpoint configuration changes are detected more accurately than source configuration changes by both adults and young children. Furthermore, when interpreting novel motion verbs, both age groups expect more fine-grained lexical distinctions in the domain of endpoint configurations compared to that of source configurations. These studies demonstrate that a cognitive-attentional bias in spatial representation and memory affects both the detail of linguistic encoding during the use of spatial language and the specificity of hypotheses about spatial referents that learners build during the acquisition of the spatial lexicon.

Previous studies have highlighted that temporal source memory can be influenced by factors such as the individual’s age and the emotional valence of the event to be remembered. In this study, we investigated how the different points of view (POVs) from which an event is presented could interact with the relationship between age-related differences and emotional valence on temporal source memory. One hundred and forty-one younger adults (aged 18–30) and 90 older adults (aged 65–74) were presented (...) with a series of emotional videos shot from different POVs (first vs. third-person) in three sessions. In the fourth session, participants were asked to indicate in which session (1, 2, or 3) they viewed each video. The results indicated that the first-person POV amplified the effects of the emotional valence on temporal source memory. Only in this experimental condition, older adults “pushed away” negative stimuli by perceiving them as more distant in time, and “kept closer” positive stimuli by perceiving them as more recent. In comparison, younger adults “kept closer” positive stimuli. These findings add to the existing literature on the positivity effect on temporal source memory and highlighted the importance of considering the POV in relation to the emotional valence. (shrink)

This exploratory study assessed the use of functional Near Infrared Spectroscopy (fNIRS) to examine hemodynamic response patterns during sentence processing. Four groups of participants: monolingual English children, bilingual Chinese-English children, bilingual Chinese-English adults and monolingual English adults were given an agent selection syntactic processing task. Bilingual child participants were classified as simultaneous or sequential bilinguals to examine the impact of first language, age of second-language acquisition (AoL2A), and the length of second language experience on behavioral performance (...) and cortical activation. Participants were asked to select the agent of four types of sentences: subject-verb-object (SVO), passive (PAS), subject-extracted relative clause (SR), and object-extracted relative clause (OR) adopted from the “Whatdunit” task by Montgomery et al. (2016). Semantic cues were removed by using inanimate nouns for agents and patients, which constrained participants to make decisions based on syntactic knowledge. Behavioral results showed greater accuracy for canonical SVO and SR sentence types than for noncanonical OR and PAS sentence types, which aligns with prior studies. Neuroimaging results revealed greater hemodynamic responses to relative clauses (i.e., SR and OR sentences) than to simple sentences (SVO and PAS), especially for Chinese-English bilinguals suggesting first-language transfer influencing sentence processing in English. The effects AoL2A and the length of second language experience showed no significant differences between simultaneous and sequential bilinguals or between bilingual adults and children for identifying the correct agent in each sentence. However, neuroimaging results demonstrated greater hemodynamic responses in right dorsolateral prefrontal cortex (DLPFC) and left inferior parietal lobule (IPL) in simultaneous bilinguals compared to sequential bilinguals and greater hemodynamic responses in left and right DLPFC and left IPL among bilingual adults. Different behavioral and neural hemodynamic response patterns afford new insights into the effects of syntactic knowledge on sentence processing. (shrink)

The faces of both adults and children can be classified accurately by sex, even in the absence of sex‐stereotyped social cues such as hair and clothing (Wild et al., 2000). Although much is known from psychological and computational studies about the information that supports sex classification for adults' faces, children's faces have been much less studied. The purpose of the present study was to quantify and compare the information available in adults' versus children's faces (...) for sex classification and to test alternative theories of how human observers distinguish male and female faces for these different age groups. We implemented four computational/neural network models of this task that differed in terms of the age categories from which the sex classification features were derived. Two of the four strategies replicated the advantage for classifying adults' faces found in previous work. To determine which of these strategies was a better model of human performance, we compared the performance of the two models with that of human subjects at the level of individual faces. The results suggest that humans judge the sex of adults' and children's faces using feature sets derived from the appropriate face age category, rather than applying features derived from another age category or from a combination of age categories.

Traditional theories of autonomy argue for rational agents who are free to make decisions about the moral law and justice. Adopting these theories entails that children lack of autonomy; they are not fully developed rational agents, and, because of that, they are unable to engage in the complex cognitive capacities required by autonomy, such as critical self-reflection or substantive independence. Amy Mullin who, as part of a new area of philosophy called Philosophy of Childhood, argues for granting children (...) minimal or local autonomy. She argues that children's attachments to those they love can be a source of autonomy in a minimal sense. She claims that it is in the relationship with those the child loves that the child is able to find meaningful activities and is able to care for someone or something. I argue that Jeff Lemire’s Essex County Vol. 1 Tales from the Farm, is a depiction of childhood that illustrates Mullin’s ideas. However, I will argue that through the use of images as a form of language, Lemire offers an insight that is unique to the medium of the graphic novel. Lemire as an artist negotiates the optical physical surfaces and uses these surfaces as a language to bridge the gap between the child and the adult and help us understand the mind of children as autonomous agents. This is an important contribution since it will allow us to understand how children can demonstrate autonomy in some of the ways in which they conduct their lives and how this may be reason enough to grant them a voice when decisions that would affect their lives are made on their behalf, such as custody cases or end of life decisions.

This paper presents preliminary findings of the project [name omitted for anonymity]. This interdisciplinary project builds on Argumentation theory and developmental sociocultural psychology for the study of children’s argumentation. We reconstruct children’s inferences in adult-child and child-child dialogical interaction in conversation in different settings. We focus in particular on implicit premises using the Argumentum Model of Topics for the reconstruction of the inferential configuration of arguments. Our findings reveal that sources of misunderstandings are more often than not (...) due to misalignments of implicit premises between adults and children; these misalignments concern material premises rather than the inferential-procedural level.

More than 200 million children under the age of 5 years are affected by malnutrition worldwide according to the World Health Organization. The Barbados Nutrition Study (BNS) is a 55-year longitudinal study on a Barbadian cohort with histories of moderate to severe protein-energy malnutrition (PEM) limited to the first year of life and a healthy comparison group. Using quantitative electroencephalography (EEG), differences in brain function duringchildhood(lower alpha1 activity and higher theta, alpha2 and beta activity) have previously been highlighted (...) between participants who suffered from early PEM and controls. In order to determine whether similar differences persisted intoadulthood, our current study used recordings obtained during a Go-No-Go task in a subsample of the original BNS cohort [population size (N) = 53] at ages 45–51 years. We found that previously malnourished adults [sample size (n) = 24] had a higher rate of omission errors on the task relative to controls (n= 29). Evoked-Related Potentials (ERP) were significantly different in participants with histories of early PEM, who presented with lower N2 amplitudes. These findings are typically associated with impaired conflict monitoring and/or attention deficits and may therefore be linked to the attentional and executive function deficits that have been previously reported in this cohort in childhood and again in middle adulthood.

This paper is concerned with the acquisition of the semantics and pragmatics of evidentiality. Evidentiality markers encode the speaker’s source for the information being reported in the utterance. While languages like English express evidentiality in lexical markers (I saw that it was raining vs. I heard that it was raining), other languages grammaticalize evidentiality. In Turkish, for all instances of past reference there is an obligatory choice between the suffixes -DI (realized as –di, -dı, -du, -dü, -ti, -tı, -tu, (...) -tü depending on the vowel harmony) and –mIs (realized as -mis, -mıs, -mus, -müs depending on the vowel harmony). These past-tense morphemes also carry evidential meanings: the morpheme –DI is used to describe witnessed events and the morpheme –mIs is used to describe information acquired from someone (hearsay) or some clue (inference).

Evidence from adult studies of deaf signers supports the dissociation between neural systems involved in processing visual linguistic and non-linguistic body actions. The question of how and when this specialization arises is poorly understood. Visual attention to these forms is likely to change with age and be affected by prior language experience. The present study used eye-tracking methodology with infants and children as they freely viewed alternating video sequences of lexical American sign language (ASL) signs and non-linguistic body actions (...) (self-directed grooming action and object-directed pantomime). In Experiment 1, we quantified fixation patterns using an area of interest (AOI) approach and calculated face preference index (FPI) values to assess the developmental differences between 6 and 11-month-old hearing infants. Both groups were from monolingual English-speaking homes with no prior exposure to sign language. Six-month-olds attended the signer’s face for grooming; but for mimes and signs, they were drawn to attend to the “articulatory space” where the hands and arms primarily fall. Eleven-month-olds, on the other hand, showed a similar attention to the face for all body action types. We interpret this to reflect an early visual language sensitivity that diminishes with age, just before the child’s first birthday. In Experiment 2, we contrasted 18 hearing monolingual English-speaking children (mean age of 4.8 years) vs. 13 hearing children of deaf adults (CODAs; mean age of 5.7 years) whose primary language at home was ASL. Native signing children had a significantly greater face attentional bias than non-signing children for ASL signs, but not for grooming and mimes. The differences in the visual attention patterns that are contingent on age (in infants) and language experience (in children) may be related to both linguistic specialization over time and the emerging awareness of communicative gestural acts.

When asked to explain their solutions to a problem, both adults and children gesture as they talk. These gestures at times convey information that is not conveyed in speech and thus reveal thoughts that are distinct from those revealed in speech. In this study, we use the classic Tower of Hanoi puzzle to validate the claim that gesture and speech taken together can reflect the activation of two cognitive strategies within a single response. The Tower of Hanoi is (...) a well‐studied puzzle, known to be most efficiently solved by activating subroutines at theoretically defined choice points. When asked to explain how they solved the Tower of Hanoi puzzle, both adults and children produced significantly more gesture‐speech mismatches—explanations in which speech conveyed one path and gesture another—at these theoretically defined choice points than they produced at non‐choice points. Even when the participants did not solve the problem efficiently, gesture could be used to indicate where the participants were deciding between alternative paths. Gesture can, thus, serve as a useful adjunct to speech when attempting to discover cognitive processes in problem‐solving. (shrink)

Adults are skilled at using language to construct/negotiate identity and to signal affiliation with others, but little is known about how these abilities develop in children. Clearly, children mirror statistical patterns in their local environment (e.g., Canadian children using zed instead of zee), but do they flexibly adapt their linguistic choices on the fly in response to the choices of different peers? To address this question, we examined the effect of group membership on 7‐ (...) to 9‐year‐olds' labeling of objects in a trivia game, exploring whether they were more likely to use a particular label (e.g., sofa vs. couch) if members of their “team” also used that label. In a preregistered study, children (N = 72) were assigned to a team (red or green) and were asked during experimental trials to answer questions—which had multiple possible answers (e.g., blackboard or chalkboard)—after hearing two teammates and two opponents respond to the same question. Results showed that children were significantly more likely to produce labels less commonly used by the community (i.e., dispreferred labels) when their teammates had produced those labels. Crucially, this effect was tied to group membership, and could not be explained by children simply repeating the most recently used label. These findings demonstrate how social processes (i.e., group membership) can guide linguistic variation in children. (shrink)

Parenthood is a highly valued life goal, independent of one’s sexual orientation. However, the majority of studies exploring young adults’ parenthood plans have relied exclusively on samples of heterosexual individuals. This study aimed (i) to explore differences in parenthood intentions as a function of sexual orientation, (ii) to investigate to what extent sociodemographic and psychological characteristics predict parenthood intentions of lesbian, gay, bisexual (LGB) and heterosexual individuals, (iii) to test the mediating effect of stigma between sexual orientation and parenthood (...) intentions, and (iv) to identify and characterize profiles of prospective parenthood (through cluster analysis). Data were gathered using an online survey from 375 self-identified LGB and heterosexual young adults without children in Portugal, with a mean age of 25.83 years old (SD = 4.49). Findings indicated that LGB individuals were less likely to intend to have children than heterosexual individuals; furthermore, among LGB individuals, lesbian women expressed stronger intentions to have children than did gay men. Similarities between heterosexual and LGB young adults were observed concerning the psychological determinants of parenthood intentions. Four distinctive profiles of prospective parenthood were identified: aspiring parents not anticipating stigma, aspiring parents anticipating stigma, childfree intent, and childfree ambivalent. Lesbian and bisexual women mostly populated the childfree ambivalent cluster, in contrast the aspiring parents anticipating stigma cluster contained an overrepresentation of men, including sexual minority men. Professionals may want to attend to communalities and specificities of prospective parenthood as a function of sexual orientation, in order to provide unbiased and culturally competent support to sexual minority individuals.

Background: Mental fatigue can impact physical demands and tactical behavior in sport-related contexts. Small-sided games are often used to develop a specific sport-related context. However, the effects of mental fatigue on physical demands and tactical behaviors during soccer SSGs have not been aggregated for systematical assessment.Objective: This systematic review was conducted to compare the effects of mental fatigue vs. control conditions in terms of the total running distance and tactical behavior of soccer players during SSGs.Methods: The data sources utilized were (...) PubMed, PsycINFO, Scielo, Scopus, SPORTDiscus, and Web of Science. The study eligibility criteria were established based on PICOS: Population: healthy youth and young adult men soccer players with regular training practice and belonging to teams with regular competitions; Intervention: exposed to mental fatigue-induced protocols only before SSGs; Comparator: control conditions before SSGs; Outcomes: physical demands and tactical behavior ; Study design: counterbalanced cross-over design; and only full-text and original articles written in English.Results: The database search initially identified 111 titles. From those, six articles were eligible for the systematic review and meta-analysis. Results showed no significant effect of fatigue on total running distance and tactical behavior.Conclusions: A non-significant effect of mental fatigue on total running distance and tactical behaviors performed by soccer players during SSGs was found in this systematic review.

We have conducted a home-based study of children′s dream reports in which parents used open-ended interviewing styles to collect 88 dream reports from their 4- to 10-year-old children in the comfortable and supportive environment of their own homes.

In contrast to previous studies, our data indicate that young children are able to give long, detailed reports of their dreams that share many formal characteristics (...) with adult dream reports. Because this wide range of dream mentation is only revealed to trusted confidants in a familiar and comfortable environment, an important implication is that the sleep laboratory may not be the best source of naturalistic dream data.

Few early debates in bioethics invigorated the field to the same extent as the one concerning whether or not young children could be used in nontherapeutic research. Though some of the issues in the debate were never fully settled, a consensus emerged, reflected in the Common Rule—that surrogates could consent to use children in such research, although once the level of risk rises above minimal, additional stipulations are required. Nontherapeutic research on cognitively impaired elderly people raises equally complex (...) ethical issues, but there has been a dearth of debate in the literature about whether such research is ethically permissible. Instead, there have been many published recommendations regarding the circumstances under which such research can occur. (shrink)

Tested the hypothesis that the younger the child the more perceptual and concrete are the concepts used. Differences were examined between children and adults (a) in using both concrete and abstract concepts as opposed to only one kind of concept, and (b) in using either concrete or abstract concepts for the 1st of 2 different kinds (concrete or abstract) of concepts. Equivalence tasks of a forced-choice type were employed to test the use of concrete and abstract (...) concepts by 45 1st graders and 45 undergraduates.

Despite the urgency of this issue, AI still struggles to represent social life. This article presents a comprehensive agent-based model that investigates status-power dynamics in groups. Kemper’s sociological status–power theory of social relationships, and a literature review on school children in middle youth, is its basis. The model allows us to investigate causation of the near-ubiquitous phenomenon that females have lower social status on average than males. Possible causes included in the model are children’s dispositional traits (kindness, beauty, (...) and physical power), schoolyard culture (social acceptability of fighting), behavioural strategy (amount of rough-and-tumble play) and the balance between public and dyadic sources of status. An agent-based model of a virtual schoolyard was created in which the children assemble in changing groups and mutually confer status. The status conferred upon a child modifies the status it holds. Rough-and-tumble is modelled as ambiguous: it is intended as a status conferral, but may be perceived as a power move. Running many trials of the model we found that in time, depending on the parameter settings, a gender-based status gap emerged. Rough-and-tumble play had more impact on emergent status differences than did physical power differences. Social acceptability of fighting also strongly moderated the resulting status gap. Placing more weight on dyadic relationship could alleviate status loss. All these model behaviours are in line with empirical findings of child behaviour studies at schools. They have face validity for social status issues in the adult world. We conclude from this that this kind of agent-based model merits use in studying the status–power dynamics of other issues in child behaviour, or indeed in social behaviour in general. (shrink)

Research on children's and adults' concepts embodies very different assumptions of how concepts are structured, as reflected in their experimental designs. Developmental studies seem to assume that categories contain highly similar objects that can all be identified from one or two examples. If concepts are more like those tested in adult experiments, research on word learning may be misleading.

Several research groups have identified a network of regions of the adult cortex that are activated during social perception and cognition tasks. In this paper we focus on the development of components of this social brain network during early childhood and test aspects of a particular viewpoint on human functional brain development: “interactive specialization.” Specifically, we apply new data analysis techniques to a previously published data set of event-related potential ~ERP! studies involving 3-, 4-, and 12-month-old infants viewing faces of (...) different orientation and direction of eye gaze. Using source separation and localization methods, several likely generators of scalp recorded ERP are identified, and we describe how they are modulated by stimulus characteristics. We then review the results of a series of experiments concerned with perceiving and acting on eye gaze, before reporting on a new experiment involving young children with autism. Finally, we discuss predictions based on the atypical emergence of the social brain network. (shrink)

Recent work asked if visual cues facilitate word segmentation in adults and infants. While adults showed better word segmentation when presented with a regular visual cue, infants did not. This difference was attributed to infants' lack of understanding that objects have labels. Alternatively, infants’ performance could reflect their difficulty with tracking and integrating multiple multimodal cues. We contrasted these two accounts by looking at the effect of visual cues on word segmentation in adults and across childhood. We (...) found that older children benefitted from the regular visual cues, but younger children, who already knew that objects have labels, did not. Knowing that objects have labels was not enough to use visual cues as an aid for segmentation. These findings show that the ability to integrate multimodal cues develops during childhood, and it is not yet adult-like in children. (shrink)

Prevailing theories of the neural basis of at least a subset of individuals with autism spectrum disorder include an imbalance of excitatory and inhibitory neurotransmission. These circuitry imbalances are commonly probed in adults using auditory steady-state responses to elicit coherent electrophysiological responses from intact circuitry. Challenges to the ASSR methodology occur during development, where the optimal ASSR driving frequency may be unknown. An alternative approach is the amplitude-modulated sweep in which the amplitude of a tone is modulated as (...) a sweep from 10 to 100 Hz over the course of ∼15 s. Phase synchrony of evoked responses, measured via intra-trial coherence, is recorded as a function of frequency. We applied such AM sweep stimuli bilaterally to 40 typically developing and 80 children with ASD, aged 6–18 years. Diagnoses were confirmed by DSM-5 criteria as well as autism diagnostic observation schedule observational assessment. Stimuli were presented binaurally during MEG recording and consisted of 20 AM swept stimuli with a duration of ∼30 s each. Peak intra-trial coherence values and peak response frequencies of source modeled responses were examined. First, the phase synchrony or inter-trial coherence of the ASSR is diminished in ASD; second, hemispheric bias in the ASSR, observed in typical development, is maintained in ASD, and third, that the frequency at which the peak response is obtained varies on an individual basis, in part dependent on age, and with altered developmental trajectories in ASD vs. TD. Finally, there appears an association between auditory steady-state phase synchrony and clinical assessment of language ability/impairment. We concluded that the AM sweep stimulus provides a mechanism for probing ASSR in an unbiased fashion, during developmental maturation of peak response frequency, peak frequencies vary, in part due to developmental age, and importantly, ITC at this peak frequency is diminished in ASD, with the degree of ITC disturbance related to clinically assessed language impairment.

A conversational implicature is an inference that consists in attributing to a speaker an implicit meaning that goes beyond the explicit linguistic meaning of an utterance. This paper experimentallyinvestigates scalar implicature, a paradigmatic case of implicature in which a speaker's use of a term like Some indicates that the speaker had reasons not to use a more informative one from the samescale, e.g. All; thus, Some implicates Not all. Pragmatic theorists like Grice would predict that a pragmatic interpretation is determined (...) only after its explicit, logical meaning is incorporated (e.g. whereSome means at least one). The present work aims to developmentally unpack this prediction by showing how younger, albeit competent, reasoners initially treat a relatively weak term logically beforebecoming aware of its pragmatic potential. Three experiments are presented. Experiment 1 presents a modal reasoning scenario offering an exhaustive set of conclusions; critical among these isparticipants' evaluation of a statement expressing Might be x when the context indicates that the stronger Must be x is true. The conversationally-infelicitous Might be x can be understood logically(e.g. as compatible with Must) or pragmatically (as exclusive to must). Results from five-, seven-, and nine-year-olds as well as adults revealed that a) seven-year-olds are the youngest to demonstratemodal competence overall and that; b) seven- and nine-year-olds treat the infelicitous Might logically significantly more often than adults do. Experiment 2 showed how training with the modal taskcan suspend the implicatures for adults. Experiment 3 provides converging evidence of the developmental pragmatic effect with the French existential quantifier Certains (Some). Whilelinguistically-sophisticated children (eight- and ten-year-olds olds) typically treat Certains as compatible with Tous (All), adults are equivocal. These results, which are consistent with unanticipatedfindings in classic developmental papers, reveal a consistent ordering in which representations of weak scalar terms tend to be treated logically by young competent participants and morepragmatically by older ones. This work is also relevant to the treatment of scalar implicatures in the reasoning literature. (shrink)

This comment argues for increased tolerance of privacy risks in the Internet activity of adults with intellectual disabilities. Excessive caution about such risks denies those individuals not only the great benefits of Internet use but also the difficult but valuable experiences of loss, disappointment, and hurt associated with those risks. A level of risk-aversion appropriate for small children will be disrespectful for adults with intellectual disabilities. To the extent that additional safeguards are justified, they are better achieved (...) through individualized security and privacy settings than through caregiver oversight. (shrink)

Kant's Grundlegung zur Metaphysik der Sitten is popular as an introduction into his philosophy and into fundamental ethics in general. Its third chapter is, nevertheless, a notoriously difficult text. According to many interpreters, it raises questions rather than answering them. This article tries to answer some questions which often remain unclear even in the secondary literature: how is the logical structure of the chapter; what exactly is the synthetic character of the categorical imperative; how does freedom function as the third, (...) connecting term in this synthesis; what is the relationship between questions concerning the possibility and the validity of the categorical imperative? In his own words, Kant wants to give here 'a deduction of the principle of morality' but also of the concept of freedom. The double use of the term 'deduction' needs an accurate interpretation. One thesis of the article is that the deduction of freedom must not be identified with the problematic deduction of the categorical imperative. The deduction of the concept of freedom has a more modest function within the proof of the possibility of the categorical imperative. This means that the question concerning the proof of its validity is still open; but the very idea that such a proof is neither possible nor necessary evokes already the notion of the factum der Vernunft.

The example of a political leader who has to decide whether he would allow the torture of a suspect in order to get information about a ticking bomb has become notorious in ethical discussions concerning the tension between moral principles and political necessity. The relation between these notions must be made as clear as possible before a sincere moral evaluation of ticking bomb situations can be given. The first section of this article considers whether the concept of political obligation is (...) different from moral and legal obligations or whether it is a special kind of moral obligation. In the second section, the idea that the dirty hands problem confronts us with the ambiguities of moral life is rejected because it would imply an untenable moral paradox. The thesis that is developed is, namely, if there is such a thing as political necessity, it must be some form of moral obligation. The third section analyses the concept of political necessity and concludes that it cannot overrule basic moral principles and that the international legal prohibition of torture must be considered to be a categorical imperative. In the last section, these ideas concerning political and moral necessity are brought in against the defence of torture, which should be tolerated in the ‘War on Terror’. There it will be argued that the use of the ticking bomb argument not only supports a highly hypocrite political practice but is also deceptive as a moral and political argument. (shrink)

This article assesses Bernard Stiegler’s critique of infantilization. Contemporary education—and society in general—would no longer develop children into adults, but would keep them in their childish state. Stiegler’s critique is explicitly inspired by Enlightenment ideals, characterized by a positive notion of maturity and a negative notion of childhood and immaturity. Infantilization is for Stiegler therefore immediately a negative development. However, Stiegler’s works also contain a positive understanding of childhood and of the extension of childish characteristics into adulthood. The (...) main thesis of this article is that this results in an unresolved tension in Stiegler’s work. I therefore propose a notion of infantilization not as solely negative, but as fundamentally ambivalent and risky. The continuation of childhood into maturity is necessary for the life of the mind, yet it can also foreclose maturity altogether. I use this new notion of infantilization to correct some of Stiegler’s radically conservative views on education and on the care for the new generations. (shrink)

Vygotsky’s concept of the zone of proximal development has brought wide attention to the role of adults in children’s learning and development. The author proposes that beyond understanding its mechanism, its use is influenced by various factors which the adult needs to be sensitive to. Through integrating related literature on the zpd and on adult-child interactions, this paper aims to shed light on the nature of adult sensitivity in actualizing the zpd. The concept is first analyzed theoretically. Two (...) types of sensitivity will then be discussed: adults’ self-awareness and their awareness of children as active players in the interaction process. Sigel’s concept of distancing is suggested as a means of enhancing one’s sensitivity. (shrink)

The present study investigates how laughter features in the everyday lives of 3-5-year old children in Swedish preschools. It examines and discusses typical laughter patterns and their functions with a particular focus on children’s and intergenerational (child-adult/educator) laughter in early education context. The research questions concern: who laughs with whom; how do adults respond to children’s laughter, and what characterizes the social situations in which laughter is used and reciprocated. Theoretically, the study answers the call for (...) sociocultural approaches that contextualize children’s everyday social interaction, e.g., in different institutions or homes, to study the diverse conditions society forms for learning, sociality and socialization and development of shared norms. Methodologically, the study makes use of mixed methods: it uses descriptive statistics that identify prevalent patterns in laughter practices and, on the basis of these results, examines social-interactional situations of children’s laughter in detail. It was found that children’s laughter tended to be directed to children and adults’ laughter tended to be directed to adults. 87% of children’s laughter was directed to other children, and adults directed their laughter to other adults 2,7 times as often as to children. The qualitative interaction analysis shows that children and adults exhibited different patterns of laughter. Children primarily sought and received affiliation through laughter in the peer group, and the adults were often focused on the institutional and educational goals of the preschool. Overall, the study shows that intergenerational reciprocal laughter was a rare occurrence and suggests that laughter between generations is interesting in that it can be seen as indicative of how children and adults handle alterity in their everyday life. By deploying multiple methods, the present study points to the importance of viewing emotion and norm sharedness in social interaction not just as a matter of communicating an emotion from one person to another, but as an intricate process of inviting the others into or negotiating the common emotional and experiential ground.

Newport addresses a fundamental question in language learning: When, why, and how do learners come to form rules, given linguistic input that varies probabilistically? She presents several case studies that confirm and extend a long‐standing theme of her work: that young learners tend to form rules from variable input, whereas adult learners store and use its statistical probabilities. Thus, child and adult learners use quite different kinds of computations when learning language; the consequence is that operating on the very same (...) input to learning results in quite different outcomes of learning.

Three experiments examined whether children and adults would use temporal information as a cue to the causal structure of a three-variable system, and also whether their judgements about the effects of interventions on the system would be affected by the temporal properties of the event sequence. Participants were shown a system in which two events B and C occurred either simultaneously (synchronous condition) or in a temporal sequence (sequential condition) following an initial event A. The causal judgements of (...) adults and 6-7-year-olds differed between the conditions, but this was not the case for 4-year-olds' judgements. However, unlike those of adults, 6-7-year-olds' intervention judgements were not affected by condition, and causal and intervention judgements were not reliably consistent in this age group. The findings support the claim that temporal information provides an important cue to causal structure, at least in older children. However, they raise important issues about the relationship between causal and intervention judgements. (shrink)

Whilst certain verbs may appear in both the intransitive inchoative and the transitive causative constructions (The ball rolled/The man rolled the ball), others may appear in only the former (The man laughed/*The joke laughed the man). Some accounts argue that children acquire these restrictions using only (or mainly) statistical learning mechanisms such as entrenchment and pre-emption. Others have argued that verb semantics are also important. To test these competing accounts, adults (Experiment 1) and children aged 5–6 (...) and 9–10 (Experiment 2) were taught novel verbs designed to be construed — on the basis of their semantics — as either intransitive-only or alternating. In support of the latter claim, participants' grammaticality judgments revealed that even the youngest group respected these semantic constraints. Frequency (entrenchment) effects were observed for familiar, but not novel, verbs (Experiment 1). We interpret these findings in the light of a new theoretical account designed to yield effects of both verb semantics and entrenchment/pre-emption. (shrink)

Researchers interested in children's understanding of mind have claimed that the ability to ascribe beliefs and intentions is a late development, occurring well after children have learned to speak and comprehend the speech of others. On the other hand, there are convincing arguments to show that verbal communication requires the ability to attribute beliefs and intentions. Hence if one accepts the findings from research into children's understanding of mind, one should predict that young children will have (...) severe difficulties in verbal communication. Conversely, if this prediction fails, this casts doubt on the claim that young children lack meta-representational skills. Using insights from Relevance Theory, an experiment was designed to test children's ability to recover a speaker's intended referent in situations in which the speaker's words underdetermine the referent. Results suggest that children's skills are comparable to those of untutored adults in similar situations. Thus this study indirectly casts doubt on the claim that young children lack meta-representational skills. (shrink)

Children and adults commonly produce more generic noun phrases (e.g., birds fly) about animals than artifacts. This may reflect differences in participants’ generic knowledge about specific animals/artifacts (e.g., dogs/chairs), or it may reflect a more general distinction. To test this, the current experiments asked adults and preschoolers to generate properties about novel animals and artifacts (Experiment 1: real animals/artifacts; Experiments 2 and 3: matched pairs of maximally similar, novel animals/artifacts). Data demonstrate that even without prior knowledge about (...) these items, the likelihood of producing a generic is significantly greater for animals than artifacts. These results leave open the question of whether this pattern is the product of experience and learned associations or instead a set of early-developing theories about animals and artifacts. (shrink)
