The unconscious-thought effect occurs when distraction improves complex decision making. Recent studies suggest that this effect is more likely to occur with low- than high-demanding distraction tasks. We discuss implications of these findings for Newell & Shanks' (N&S's) claim that evidence is lacking for the intervention of unconscious processes in complex decision making.

Inattentional Blindness occurs when observers engaged in resource-consuming tasks fail to see unexpected stimuli that appear in their visual field. Eye movements were recorded in a dynamic IB task where participants tracked targets amongst distractors. During the task, an unexpected stimulus crossed the screen for several seconds. Individuals who failed to report the unexpected stimulus were deemed to be IB. Being IB was associated with making more fixations and longer gaze times on distractor stimuli, being less likely to (...) fixate the unexpected stimulus, and having lower working memory capacity than those who were not IB. Noticing the unexpected stimulus was not contingent upon fixating it, suggesting that some individuals processed the unexpected stimulus via covert attention. The findings support earlier research on working memory and IB. In addition, IBs were less efficient attentional allocators than those who were not IB, as reflected in their eye tracking of irrelevant distractors. (shrink)

ObjectiveTo assess distracted attention and performance on a computer task following completion of a sustained attention and acute media multitasking task among adolescents with varying self-reported usual media multitasking.MethodsNinety-six 13- to 17-year-olds played the video game Tetris following completion of a Go/No-go paradigm to measure sustained attention in the presence of distractors, an acute media multitasking, or a passive viewing condition. Adolescents completed the conditions on separate visits in randomized order. Sustained attention was measured within the Go/No-go (...) class='Hi'>task by measuring errors of omission. Distracted attention while playing the Tetris task was measured by computing eye tracking measures of attention to irrelevant distractor images that bordered the Tetris game. Participants also self-reported their daily media multitasking.ResultsThe Go/No-go task revealed important qualitative differences in sustained attention among low and high usual media multitaskers. There was a uniform improvement in sustained attention among low usual media multitaskers, demonstrated by a consistent linear decrease in omission errors. Among high usual media multitaskers, there was initially a decrease in sustained attention followed by an increase. Completing the Go/No-go task also statistically significantly reduced distractibility and increased performance while playing Tetris compared to the passive viewing condition, but only among those with low usual media multitasking. There was a non-statistically significant trend that completing the acute media multitask increased subsequent distractibility and performance while playing Tetris among high media multitaskers.ConclusionIn this sample of adolescents, practicing a sustained attention task reduces distractibility and improves task performance among those who have low levels of usual media multitasking.

Previous research has investigated factors that contribute to the development of different risk-taking behaviors, such as can occur on lab-based behavioral risky decision making tasks. On several of the most common tasks, participants must develop an adequate understanding of the relative risks and benefits associated with each decision in order to learn to decide advantageously. However, contextual factors can affect the decision making process and one’s ability to weigh the risks and benefits of a decision. The present study investigates the (...) extent to which music may be an additional contextual factor that can disrupt decision making and other executive functions. Across four studies we examine whether having music playing passively in the background or having participants actively listen to music affects performance on measures of risky decision making, working memory, processing speed, and problem solving. Participants reported greater distraction for rock music than classical music in the passive listening studies but did not report any differences in distraction across conditions in the active listening studies. Despite this self-reported increased level of distraction, few significant differences were found in task performance across groups and across studies. The Angling Risk Task was sensitive to differences in risk by condition, with music leading to greater risk-taking in a passive listening study, but less risk-taking in an active listening study, compared to no music. The extent to which music serves as a contextual factor disrupting performance on measures of risky decision making and other executive functions may depend in part on whether individuals are actively versus passively listening to the music.

Current cognitive models of addiction imply that speeded detection and increased distraction from substance cues might both independently contribute to the persistence of addictive behavior. Speeded detection might lower the threshold for experiencing craving, whereas increased distraction might further increase the probability of entering a bias-craving-bias cycle, thereby lowering the threshold for repeated substance use. This study was designed to examine whether indeed both attentional processes are involved in substance use disorders. Both attentional processes were indexed by an Odd-One-Out visual (...) search task in individuals diagnosed with alcohol use disorder and cannabis use disorder. To test whether the detection and/or the distraction component are characteristic for AUD and CUD, their indices were compared with matched individuals without these diagnoses. Individuals with CUD showed speeded detection of cannabis cues; the difference in detection between AUD and the comparison group remained inconclusive. Neither the AUD nor the CUD group showed more distraction than the comparison groups. The sample size of the CUD group was relatively small. In addition, participants made relatively many errors in the attentional bias task, which might have lowered its sensitivity to detect ABs. The current study provided no support for the proposed role of increased distraction in CUD and AUD. The findings did, however, provide support for the view that speeded detection might be involved in CUD. Although a similar trend was evident for AUD, the evidence was weak and remained therefore inconclusive. (shrink)

Consider the much-discussed case of the distracted driver, who is alleged to successfully navigate his car for miles despite being completely oblivious to his visual states. Perhaps he is deeply engrossed in the music playing over the radio or in philosophical reflection, and as a result he goes about unaware of the scene unfolding before him on the road. That the distracted driver has visual experiences of which he is not aware is a possibility that first-order representationalists happily accept, but (...) higher-order representationalists steadfastly deny. HOR claims that perceptual states become conscious only as the object of higher-order states; perceptual states are not intrinsically conscious. According to HOR, since the driver is supposed to be completely distracted by other cognitive tasks, he cannot form higher-order representations of his visual states, with the result that those states are disqualified as experiences.1 HOR theories have come in two flavors, those that claim that the relevant higher-order representations are thought-like and those that that rely on an inner perception-like mechanism that is directed toward one.

The ability to resist distracting stimuli whilst voluntarily focusing on a task is fundamental to our everyday cognitive functioning. Here, we investigated how this ability develops, and thereafter declines, across the lifespan using a single task/experiment. Young children (5–7 years), older children (10–11 years), young adults (20–27 years), and older adults (62–86 years) were presented with complex visual scenes. Endogenous (voluntary) attention was engaged by having the participants search for a visual target presented on either the left (...) or right side of the display. The onset of the visual scenes was preceded – at stimulus onset asynchronies (SOAs) of 50, 200, or 500 ms – by a task-irrelevant sound (an exogenous crossmodal spatial distractor) delivered either on the same or opposite side as the visual target, or simultaneously on both sides (cued, uncued, or neutral trials, respectively). Age-related differences were revealed, especially in the extreme age-groups, which showed a greater impact of crossmodal spatial distractors. Young children were highly susceptible to exogenous spatial distraction at the shortest SOA (50 ms), whereas older adults were distracted at all SOAs, showing significant exogenous capture effects during the visual search task. By contrast, older children and young adults' search performance was not significantly affected by crossmodal spatial distraction. Overall, these findings present a detailed picture of the developmental trajectory of endogenous resistance to crossmodal spatial distraction from childhood to old age and demonstrate a different efficiency in coping with distraction across the four age-groups studied.

This article reviews recent cognitive and neurological approaches to the study of attention. It argues that such research is based on the notion that attention has a positive cognitive function selecting, like a sieve or a filter, elements from the background and foreground, to then be processed by the brain and made conscious when required. These approaches fail to explain cognitive overload and recent findings demonstrating that recognition and understanding—sensory, visual and semantic—also occur prior to attention. Merleau-Ponty and Freud offer (...) a different model: a negative distractive attention. Negative distractive attention serves as a threshold for stimuli excluded by neurological processes regulating overload and ensuring that consciousness can concentrate on the singularity of its objects. Such approach to attention explains how one can drive and talk. It is not a positive multi-tasking model but a negative distractive one. (shrink)

Summary This paper re?examines some aspects of the ?real books?reading scheme books? debate which erupted into the British literacy education field a decade ago. It argues that the debate was not only over?polarised but that it did not take appropriate account of a scholarly review of related research by Professor Jeanne Chall which had been published a few years earlier. Subsequent research has further supported Chall's arguments. The paper indicates how the use of reading scheme and real books can be (...) reconciled in curriculum programmes which are sensitive to how learning needs change in the course of early literacy development. It also notes the related significance of some current developments in the field, such as the National Literacy Project and the Literacy Task Force. (shrink)

A. Schopenhauer has proposed some intriguing and even challenging views on the link of representation to sensoriality. Since this has become a key issue for studies on spectatorship, some aspects of Schopenhauer’s philosophy could be critically examined within the framework of audio-visual media. The present article undertakes this task with a focus on two different notions that concern spectatorship. First, it examines whether the Schopnehaurian conception of a representational ‘motive’ can be incorporated into the study of a cinematic product (...) and suggests that this would involve a ‘realist’ account of cinema and audio-visual culture. Second, it associates the notion of ‘distraction’, which, since Benjamin, has been central to the reception of audio-visuality, with the philosophy of Schopenhauer. The article argues that current audio-visual culture resides in a simultaneous interiorization and exteriorization of ‘distraction’. In the light of this analysis, the work of Schopenhauer appears to be of use for understanding the wide distribution and deep insertion of audio-visuality in contemporary culture. (shrink)

Attention has a role in much of perception, thought, and action. On the erotetic theory, the functional role of attention is a matter of the relationship between questions and what counts as answers to those questions. Questions encode the completion conditions of tasks for cognitive control purposes, and degrees of attention are degrees of sensitivity to the occurrence of answers. Questions and answers are representational contents given precise characterizations using tools from formal semantics, though attention does not depend on language. (...) The erotetic theory proposes an integrated account of attention in cognitive control and of attentional focus in perception. The functional role of attentional focus on objects, properties, and locations has to do with picking out something that corresponds to what a task is ‘about’. The erotetic theory of attention opens new avenues in theorizing about the relationship between attention, representational content, phenomenal character, and practical reason. A novel representationalist account of salience is proposed. The theory also provides an account of distraction that suggests when distraction is a defect in practical reasoning. (shrink)

Initially “meaningless” and randomly generated sounds can be learned over exposure. This is demonstrated by studies where repetitions of randomly determined sound patterns are detected better if they are the same sounds presented on previous trials than if they are novel. This experiment posed two novel questions about this learning. First, does familiarization with a sound outside of the repetition detection context facilitate later performance? Second, does familiarization enhance performance when repeats are interleaved with distracters? Listeners were first trained to (...) categorize a unique pattern of synchronous complex tone trains from other tone trains with similar qualities. They were then tasked to detect repeated pattern presentations interleaved with similar distracters in 4.2 s long excerpts. The familiarized pattern, an unfamiliar pattern that remained fixed throughout, or patterns that were uniquely determined on each trial could be presented as repeats. FF patterns were learned at a faster rate and achieved higher repetition detection sensitivity than UF and UU patterns. Similarly, FF patterns also showed steeper learning slopes in their response times than UF patterns. The data show that familiarity with a “meaningless” sound pattern on its own can facilitate repetition detection even in the presence of distracters. Familiarity effects become most apparent in the potential for learning. (shrink)

The impact of bilingual education and bilingual experience on working memory has been an important and controversial issue in the field of psycholinguistics. Taking Chinese-English bilinguals as an example, this study aims to investigate the differences in emotional working memory between proficient and non-proficient bilinguals by using delayed matching-to-sample task paradigm and more complex n-back task in the context of emotion. The results show that proficient bilinguals have better performance on both of the two working memory tasks than (...) non-proficient bilinguals, and the advantage effects were more apparent under high memory load conditions. Besides, the negative emotion context has a positive impact on complex n-back tasks. This study supports the notion that bilingual experience can promote the development of an individual’s cognitive ability and enable individuals to possess more advantages in working memory even in the presence of emotional distractions.

Distractibility is one of the key features of attention deficit hyperactivity disorder and has been associated with alterations in the neural orienting and alerting networks. Task-irrelevant stimuli are thus expected to have detrimental effects on the performance of patients with ADHD. However, task-irrelevant presentation of novel sounds seems to have the opposite effect and improve subsequent attentional performance particularly in patients with ADHD. Here, we aimed to understand the neural modulations of the attention networks underlying these improvements. Fifty (...) boys participated in a functional magnetic resonance imaging study in which unique or repeatedly presented sounds were placed before a visual flanker task in 2/3 of the trials. We found that presenting any sound improved task performance in all participants, but the underlying neural mechanisms differed for the type of sound. Familiar sounds led to a stronger increase in activity in the left posterior insula in patients with ADHD compared to typically developing peers. Novel sounds led to activations of the fronto-temporoparietal ventral attention network, likewise in ADHD and TD. These changes in signaling by novelty in the right inferior frontal gyrus were directly related to improved response speed showing that neural orienting network activity following novel sounds facilitated subsequent attentional performance. This mechanism of behavioral enhancement by short distractions could potentially be useful for cognitive trainings or homework situations. (shrink)

Using social information is not indiscriminate and being able to choose what to copy and from whom to copy is critical. Dogs are able to learn socially, to recognize, and respond to dog as well as human emotional expressions, and to make reputation-like inferences based on how people behave towards their owner. Yet, the mechanisms dogs use for obtaining and utilizing social information are still to be fully understood, especially concerning whether emotional cues influence dogs’ social learning. Therefore, our main (...) aim was to test the hypothesis that an emotionally charged interaction with the demonstrator of a “V” detour task prior to testing would affect subjects’ performance, by: changing the value of the information provided by the demonstrator or changing the valence of the learning environment. Our experimental design consisted of three phases: pre-test ; emotional display ; test. Only dogs that failed in pre-test were considered for analysis. We analyzed four dependent variables: success, time to solve the task, latency to reach the fence and matching the side of demonstration. For each, we used four models to investigate the effect of demographic factors; experimental design factors ; behavior of the dog; and side chosen and matching. All models took into account all trials and the first trials only. Our findings corroborate previous studies of social learning, but present no evidence to sustain our hypothesis. We discuss the possibility of our stimuli not being salient enough in a task that involves highly motivating food and relies on long and highly distracting interval between phases. Nevertheless, these results represent an important contribution to the study of dog behavior and social cognition and pave the way for further investigations. (shrink)

The mere exposure effect is the increase in positive affect that results from the repeated exposure to previously novel stimuli. We sought to determine if judgments other than affective preference could reliably produce a mere exposure effect for two-dimensional random shapes. In two experiments, we found that brighter and darker judgments did not differentiate target from distracter shapes, liking judgments led to target selection greater than chance, and disliking judgments led to distracter selection greater than chance. These results for brighter, (...) darker, and liking judgments were obtained regardless of whether shape recognition was greater (Experiment 1) or not greater (Experiment 2) than chance. Effects of prior exposure to novel shapes were reliably observed only for affective judgment tasks. These results are inconsistent with general predictions made by the nonspecific activation hypothesis, but not the affective primacy or perceptual fluency hypotheses which were discussed in terms of cognitive neuroscience research.

The failure of the UN Security Council to adequately and effectively address the Syrian crisis has brought renewed scrutiny to the veto and its capricious use during mass atrocity situations. In response to these concerns, the idea of a code of conduct to regulate the exercise of the veto during humanitarian situations is now being increasingly advanced by several states, including France and the United Kingdom. This paper disputes the utility of such a code and argues that it would not (...) make any significant difference to the way mass atrocity crimes are addressed. I examine three core arguments often extended to justify the merit and the utility of the norm: the circumvention argument, the naming and shaming argument, and the Charter reform argument. I show how each of these arguments is undermined by mistaken notions about the norm's procedural effectiveness, and the role the veto plays in cases of what Simon Chesterman calls “inhumanitarian noninterventions.” Additionally, drawing on interviews conducted with diplomats at the United Nations in New York, I present evidence that resistance to a code of conduct comes not only from the permanent five members of the Council but also from the nonpermanent members, further imperiling the idea's capacity to effect change. Ultimately, I contend that the current global effort to curtail the influence of the veto is nothing more than a journey down the rabbit hole: exciting, but ultimately distracting. (shrink)

Research on cognitive control has sparked increasing interest in recent years, as it is an important prerequisite for goal oriented human behavior. The paced auditory serial addition task has been used to test and train cognitive control functions. This adaptive, challenging task includes continuous performance feedback. Therefore, additional cognitive control capacities are required to process this information along with the already high task-load. The underlying neural mechanisms, however, are still unclear. To explore the neural signatures of the (...) PASAT and particularly the processing of distractive feedback information, feedback locked event-related potentials were derived from 24 healthy participants during an adaptive 2-back version of the PASAT. Larger neural activation after negative feedback was found for feedback related negativity, P300, and late positive potential. In early stages of feedback processing, a larger difference between positive and negative feedback responses was associated with poorer overall performance. This association was inverted in later stages. Together, our findings indicate stage-dependent associations between neural activation after negative information and cognitive functioning. Conceivably, increased early responses to negative feedback signify distraction, whereas higher activity at later stages reflects cognitive control processes to preserve ongoing performance.

Two experiments are described that investigate the effects of attention in moderating evaluative conditioning (EC) effects in a picture‐picture paradigm in which previously discovered experimental artifacts (e.g., Field & Davey, 1999 Field, AP, and Davey, GCL, (1999). Reevaluating evaluative conditioning: A nonassociative explanation of conditioning effects in the visual evaluative conditioning paradigm, Journal of Experimental Psychology. Animal Behavior Processes 25 ((1999)), pp. 211–224.[Crossref], [PubMed], [Web of Science ®], [Google Scholar]) were overcome by counterbalancing conditioned stimuli (CSs) and unconditioned stimuli (USs) (...) across participants. Conditioned responses for individuals who had attention enhanced were compared against a control group and groups for whom attention was impeded using a distracter task. In a second experiment the effects of attention were dissociated from those of contingency awareness by using backward‐masked US presentations. The results of these experiments indicate that although associative EC effects may not be disrupted by a lack of contingency awareness, attention is an important factor in establishing conditioning. These results shed some light onto the possible boundary conditions that could explain past inconsistencies in obtaining EC effects in the visual paradigm. (shrink)

Previous research has found that depression is characterised by biased processing of emotional information. Although most studies have examined cognitive biases in isolation, simultaneous examination of multiple biases is required to understand how they may interact and influence one another to produce depression vulnerability. In this study, the attention and memory biases of currently depressed, previously depressed, and never depressed women were examined using the same stimuli and a unified methodology. Participants viewed negative, positive, and neutral words while their eye (...) gaze was tracked and recorded. After a distraction task, participants completed an incidental recognition test that included words from the eye-tracking task and new words. The results supported the hypothesised mediation model for positive words: currently depressed women had a reduced attention bias for positive words and, in turn, had poorer memory for positive words relative to never depressed women. Previously depressed women, however, showed a lack of coherence between attention and memory biases for positive words. The groups did not differ in their attention or memory biases for negative words. The findings provide novel evidence in support of a causal link between the absence of protective attention and memory biases for positive information in clinical depression. (shrink)

Motto-goals describe a desired mind-set and provide a person with a guiding principle of how to approach a personal goal or obligation. We propose that motto-goals can be conceptionalized as individually created metaphors and that the figurative, metaphorical language and the characteristics of the formation process make them effective in changing the perception of unpleasant personal obligations as more inherently enjoyable and raise vitality levels. To test whether a newly devised minimalistic motto-goal intervention can make goal striving more attractive and (...) energize goal-oriented action in relation to an unpleasant obligation, two experimental studies were conducted. In Study 1 the motto-goal condition led to stronger anticipation of activity related incentives and vitality compared to a distraction task. The effect on vitality was partially mediated by a change in feelings of autonomy. Study 2 replicated the effects compared to a placebo intervention and further found motto-goals to be specifically effective in increasing the anticipation of activity related incentives as opposed to outcome related incentives. The results support that applying motto-goals built with a newly developed minimalist motto-goal intervention can influence the subjective experience of individuals faced with a previously unpleasant obligation.
