We propose a realistic device for detecting objects almost without transferring a single quantum of energy to them. The device can work with an efficiency close to 100% and relies on two detectors counting both presence and absence of the objects. Its possible usage in performing fundamental experiments as well as possible applications are discussed.

The central project of the Critique of Pure Reason is to answer two sets of questions: What can we know and how can we know it? and What can't we know and why can't we know it? The essays in this collection are intended to help students read the Critique of Pure Reason with a greater understanding of its central themes and arguments, and with some awareness of important lines of criticism of those themes and arguments.

Bering's argument that human beings are endowed with a cognitive system dedicated to forming illusory representations of psychological immortality relies on the claim that children's beliefs in the afterlife are not the result of religious teaching. We suggest four reasons why this claim is unsatisfactory.

This paper introduces a new, expanded range of relevant cognitive psychological research on collaborative recall and social memory to the philosophical debate on extended and distributed cognition. We start by examining the case for extended cognition based on the complementarity of inner and outer resources, by which neural, bodily, social, and environmental resources with disparate but complementary properties are integrated into hybrid cognitive systems, transforming or augmenting the nature of remembering or decision-making. Adams and Aizawa, noting this distinctive complementarity argument, (...) say that they agree with it completely: but they describe it as “a non-revolutionary approach” which leaves “the cognitive psychology of memory as the study of processes that take place, essentially without exception, within nervous systems.” In response, we carve out, on distinct conceptual and empirical grounds, a rich middle ground between internalist forms of cognitivism and radical anti-cognitivism. Drawing both on extended cognition literature and on Sterelny’s account of the “scaffolded mind” (this issue), we develop a multidimensional framework for understanding varying relations between agents and external resources, both technological and social. On this basis we argue that, independent of any more “revolutionary” metaphysical claims about the partial constitution of cognitive processes by external resources, a thesis of scaffolded or distributed cognition can substantially influence or transform explanatory practice in cognitive science. Critics also cite various empirical results as evidence against the idea that remembering can extend beyond skull and skin. We respond with a more principled, representative survey of the scientific psychology of memory, focussing in particular on robust recent empirical traditions for the study of collaborative recall and transactive social memory. We describe our own empirical research on socially distributed remembering, aimed at identifying conditions for mnemonic emergence in collaborative groups. Philosophical debates about extended, embedded, and distributed cognition can thus make richer, mutually beneficial contact with independently motivated research programs in the cognitive psychology of memory.

Children aged 7 and 11 years were interviewed about death in the context of two different narratives. Each narrative described the death of a grandparent but one narrative provided a secular context whereas the other provided a religious context. Following each narrative, children were asked to judge whether various bodily and mental processes continue to function after death, and to justify their judgment. Children displayed two different conceptions of death. They often acknowledged that functioning ceases at death and offered appropriate (...) biological justifications for that judgment. However, they also claimed that functioning continues after death and offered appropriate religious justifications. The tendency to claim that functioning continues after death was more frequent among older children than younger children, more frequent in the context of the religious narrative as opposed to the secular narrative and more frequent with respect to mental processes than bodily processes. Particularly among older children, two distinct conceptions of death appear to co-exist: a biological conception in which death implies the cessation of living processes and a metaphysical conception in which death marks the beginning of the afterlife.

Transactive memory theory describes the processes by which benefits for memory can occur when remembering is shared in dyads or groups. In contrast, cognitive psychology experiments demonstrate that social influences on memory disrupt and inhibit individual recall. However, most research in cognitive psychology has focused on groups of strangers recalling relatively meaningless stimuli. In the current study, we examined social influences on memory in groups with a shared history, who were recalling a range of stimuli, from word lists to personal, (...) shared memories. We focused in detail on the products and processes of remembering during in-depth interviews with 12 older married couples. These interviews consisted of three recall tasks: (1) word list recall; (2) personal list recall, where stimuli were relevant to the couples’ shared past; and (3) an open-ended autobiographical interview. We conducted these tasks individually and then collaboratively two weeks later. Across each of the tasks, although some couples demonstrated collaborative inhibition, others demonstrated collaborative facilitation. We identified a number of factors that predicted collaborative success, in particular, group-level strategy use. Our results show that collaboration may help or hinder memory, and certain interactions are more likely to produce collaborative benefits. (shrink)

Do the previous termviewpoint costsnext term incurred when naming rotated familiar objects arise during initial identification or during previous termconsolidation?next term To answer this question we employed an attentional blink (AB) task where two target objects appeared amongst a rapid stream of distractor objects. Our assumption was that while both targets and distractors undergo initial identification only targets are consolidated in a form that allows overt report. We presented line drawings of objects with a usual upright canonical orientation, and separately (...) manipulated the orientation of targets and distractors. In two experiments, targets were defined by colour, whereas in a third experiment they were defined by semantic category. Target 1 orientation influenced the AB, with objects rotated by 90° causing a larger second target deficit than upright and upside-down objects. However, distractor orientation did not affect the magnitude of the second target deficit, regardless of whether targets were defined by colour or semantic category. Taken together, these findings suggest that the visual representations involved in the preliminary recognition of familiar objects are previous termviewpointnext term-invariant and that previous termviewpoint costsnext term are incurred when these objects are consolidated for report.

Despite recent research showing that children rapidly interpret human action in terms of intention, a long tradition of empirical research on moral development and recent conceptual analyses of the deontic domain suggest that children do not apply their understanding of intention to the deontic domain. However, two experiments are described showing that children do make that connection. Preschool children heard stories in which a protagonist was obliged to meet a particular condition if an action was to be taken (e.g. obliged (...) to wear a coat if playing outside). When shown four pictures depicting each possible combination of: (1) the protagonist either performing the action or not, and (2) deliberately or accidentally failing to meet the obligation, children appropriately identified the protagonist as naughty when he or she was depicted as deliberately not meeting the obligation while performing the action. The findings proved to be robust across two different cultural settings. Implications for research on children’s developing theory of mind and their understanding of deontic concepts are discussed.

Across two studies, a wide age range of participants was interviewed about the nature of death. All participants were living in rural Madagascar in a community where ancestral beliefs and practices are widespread. In Study 1, children (8–17 years) and adults (19–71 years) were asked whether bodily and mental processes continue after death. The death in question was presented in the context of a narrative that focused either on the corpse or on the ancestral practices associated with the afterlife. Participants (...) aged 8 years and older claimed that death brings an end to most bodily and mental processes. Nevertheless, particularly in the context of the religious narrative, they claimed that certain mental processes continue even after death. This assertion of an afterlife was more evident among adults than children, especially with respect to cognitive processes, such as knowing and remembering. In Study 2, 5‐ and 7‐year‐olds were asked similar questions in connection with the death of a bird and a person. Seven‐year‐olds consistently claimed that bodily and mental processes cease at death, whereas 5‐year‐olds were unsystematic in their replies. Together, the two studies replicate and extend findings obtained with Western children showing that, in the course of development, different conceptions of death are elaborated—a biological conception in which death terminates living processes and a religious conception in which death marks the beginning of a new form of spiritual existence.

What is the nature of children's trust in testimony? Is it based primarily on evidential correlations between statements and facts, as stated by Hume, or does it derive from an interest in the trustworthiness of particular speakers? In this essay, we explore these questions in an effort to understand the developmental course and cognitive bases of children's extensive reliance on testimony. Recent work shows that, from an early age, children monitor the reliability of particular informants, differentiate between those who make (...) true and false claims and keep that differential accuracy in mind when evaluating new information from these people. We argue that this selective trust is likely to involve the mentalistic appraisal of speakers rather than surface generalizations of their behavior. Finally, we review the significance of children's deference to adult authority on issues of naming and categorization. In addition to challenging a purely inductive account of trust, these and other findings reflect a potentially rich set of tools brought by children to the task of learning from people's testimony.

Developmental psychologists have often portrayed young children as stubborn autodidacts who ignore the testimony of others. Yet the basic design of the human cognitive system indicates an early ability to co-ordinate information derived from first-hand observation with information derived from testimony. There is no obvious tendency to favour the former over the latter. Indeed, young children are relatively poor at monitoring whether they learned something from observation or from testimony. Moreover, the processes by which children and adults understand and remember (...) a sequence of events appear to be similar, whether they witness that sequence or are told about it. Children’s early receptivity to testimony raises the question of whether and how children discern what testimony is reliable. Arguably, before the emergence of reflective judgement, children are equipped with a tacit filtering device. To be understood, any new piece of testimony typically needs to be consistent with, and integrated into, what is already known about the topic in question. Children’s impoverished knowledge base will make that integrative process relatively slow. Thus, children’s early ignorance may often save them from misplaced credulity.Author Keywords: Trust; Testimony; Sources ; Cognitive development; Situation model. (shrink)

Children's utterances from late infancy to 3 years of age were examined to infer their conception of knowledge. In Study 1, the utterances of two English-speaking children were analysed and in Study 2, the utterances of a Mandarin-speaking child were analysed – in both studies, for their use of the verb know. Both studies confirmed that know and not know were used to affirm, query or deny knowledge, especially concerning an ongoing topic of conversation. References to a third party were (...) rare. By implication, 2-year-olds have a conception of knowledge that underpins their exchange of information in conversation. Implications for the child's developing theory of mind are discussed.

Conversations about the past can involve voicing and silencing; processes of validation and invalidation that shape recall. In this experiment we examined the products and processes of remembering a significant autobiographical event in conversation with others. Following the death of Australian celebrity Steve Irwin, in an adapted version of the collaborative recall paradigm, 69 participants described and rated their memories for hearing of his death. Participants then completed a free recall phase where they either discussed the event in groups of (...) three or wrote about the event on their own. Finally, participants completed the original questionnaire again, both 1 week and 1 month after the free recall phase. Discussion influenced later memories for hearing of Irwin’s death, particularly memories for emotion and shock. Qualitative analysis of the free recall phase suggested that during conversation a shared understanding of the event developed, but that emotional reactions to the event were silenced in ways that minimised the event’s impact. These findings are discussed in terms of the processes and consequences of sharing public and personal memories in conversation. (shrink)

Children learn about the world from the testimony of other people, often coming to accept what they are told about a variety of unobservable and indeed counter-intuitive phenomena. However, research on children’s learning from testimony has paid limited attention to the foundations of that capacity. We ask whether those foundations can be observed in infancy. We review evidence from two areas of research: infants’ sensitivity to the emotional expressions of other people; and their capacity to understand the exchange of information (...) through non-verbal gestures and vocalization. We conclude that a grasp of the bi-directional exchange of information is present early in the second year. We discuss the implications for future research, especially across different cultural settings. (shrink)

Experimental memory research has traditionally focused on the individual, and viewed social influence as a source of error or inhibition. However, in everyday life, remembering is often a social activity, and theories from philosophy and psychology predict benefits of shared remembering. In a series of studies, both experimental and more qualitative, we attempted to bridge this gap by examining the effects of collaboration on memory in a variety of situations and in a variety of groups. We discuss our results in (...) terms of a functional view of collaborative remembering, and consider when and in what ways remembering with others might help or hinder memory. (shrink)

Most literature on the ethics of global warming focuses on the obligations of industrialized states to reduce their emissions of greenhouse gases and to help poor countries do likewise. These books are no exception, arguing that the issue is a matter of international justice and equity.

The question of whether object recognition is orientation-invariant or orientation-dependent was investigated using a repetition blindness (RB) paradigm. In RB, the second occurrence of a repeated stimulus is less likely to be reported, compared to the occurrence of a different stimulus, if it occurs within a short time of the first presentation. This failure is usually interpreted as a difficulty in assigning two separate episodic tokens to the same visual type. Thus, RB can provide useful information about which representations are (...) treated as the same by the visual system. Two experiments tested whether RB occurs for repeated objects that were either in identical orientations, or differed by 30, 60, 90, or 180°. Significant RB was found for all orientation differences, consistent with the existence of orientation-invariant object representations. However, under some circumstances, RB was reduced or even eliminated when the repeated object was rotated by 180°, suggesting easier individuation of the repeated objects in this case. A third experiment confirmed that the upside-down orientation is processed more easily than other rotated orientations. The results indicate that, although object identity can be determined independently of orientation, orientation plays an important role in establishing distinct episodic representations of a repeated object, thus enabling one to report them as separate events.

How do children acquire beliefs from testimony? In this chapter, we discuss children's trust in testimony, their sensitivity to and use of defeaters, and their appeals to positive reasons for trusting what other people tell them. Empirical evidence shows that, from an early age, children have a tendency to trust testimony. However, this tendency to trust is accompanied by sensitivity to cues that suggest unreliability, including inaccuracy of the message and characteristics of the speaker. Not only are children sensitive to (...) evidence of unreliability, but they are also sensitive to the positive reasons a speaker may have for the reliability of their testimony. This evidence is discussed in relation to reductivist and non-reductivist viewpoints. (shrink)

People live and age together in social groups. Across a range of outcomes, research has identified interdependence in the cognitive and health trajectories of ageing couples. Various types of memory decline with age and people report using a range of internal and external, social, and material strategies to compensate for these declines. While memory compensation strategies have been widely studied, research so far has focused only on single individuals. We examined interdependence in the memory compensation strategies reported by spouses within (...) 58 older couples. Couples completed the Memory Compensation Questionnaire, as well as an open-ended interview about their memory compensation practices. We found that internal, intra-individual memory compensation strategies were not associated within couples, but external, extra-individual strategies showed interdependence. Individuals’ scores on material/technological compensation strategies were positively correlated with their partners’. Reported reliance on a spouse was higher for men and increased with age. Our open-ended interviews yielded rich insights into the complex and diverse resources that couples use to support memory in day-to-day life. Particularly evident was the extent of interaction and coordination between social and material compensation, such that couples jointly used external compensation resources. Our results suggest that individuals’ reports of their compensation strategies do not tell the whole story. Rather, we propose that older couples show interdependence in their memory compensation strategies, and adopt complex systems of integrated material and social memory compensation in their day-to-day lives.

Psychologists have emphasized children's acquisition of information through firsthand observation. However, many beliefs are acquired from others' testimony. In two experiments, most 4yearolds displayed sceptical trust in testimony. Having heard informants' accurate or inaccurate testimony, they anticipated that informants would continue to display such differential accuracy and they trusted the hitherto reliable informant. Yet they ignored the testimony of the reliable informant if it conflicted with what they themselves had seen. By contrast, threeyearolds were less selective in trusting a reliable (...) informant. Thus, young children check testimony against their own experience and increasingly recognise that some informants are more trustworthy than others. (shrink)
