Further Evidence That Sleep Deprivation Effects and the Vigilance Decrement Are Functionally Equivalent: Comment on Altmann (2018)

Veksler and Gunzelmann (2018) argue that the vigilance decrement and the deleterious effects of sleep loss reflect functionally equivalent degradations in cognitive processing and performance. Our account is implemented in a cognitive architecture, where these factors produce breakdowns in goal‐directed cognitive processing that we refer to as microlapses. Altmann (2018) raises a number of challenges to microlapses as a unified account of these deficits. Under scrutiny, however, the challenges do little to discredit the theory or conclusions in the original paper. In our response, we address the most serious challenges. In so doing, we provide additional support for the theory and mechanisms, and we highlight opportunities for extending their explanatory breadth.     

Complexity and coherency: integrating information in the brain

The brains of higher mammals are extraordinary integrative devices. Signals from large numbers of functionally specialized groups of neurons distributed over many brain regions are integrated to generate a coherent, multimodal scene. Signals from the environment are integrated with ongoing, patterned neural activity that provides them with a meaningful context. We review recent advances in neurophysiology and neuroimaging that are beginning to reveal the neural mechanisms of integration. In addition, we discuss concepts and measures derived from information theory that lend a theoretical basis to the notion of complexity as integration of information and suggest new experimental tests of these concepts.     

Do Extraordinary Claims Require Extraordinary Evidence?

In 1979 astronomer Carl Sagan popularized the aphorism “extraordinary claims require extraordinary evidence” (ECREE). But Sagan never defined the term “extraordinary.” Ambiguity in what constitutes “extraordinary” has led to misuse of the aphorism. ECREE is commonly invoked to discredit research dealing with scientific anomalies, and has even been rhetorically employed in attempts to raise doubts concerning mainstream scientific hypotheses that have substantive empirical support. The origin of ECREE lies in eighteenth-century Enlightenment criticisms of miracles. The most important of these was Hume’s essay On Miracles. Hume precisely defined an extraordinary claim as one that is directly contradicted by a massive amount of existing evidence. For a claim to qualify as extraordinary there must exist overwhelming empirical data of the exact antithesis. Extraordinary evidence is not a separate category or type of evidence--it is an extraordinarily large number of observations. Claims that are merely novel or those which violate human consensus are not properly characterized as extraordinary. Science does not contemplate two types of evidence. The misuse of ECREE to suppress innovation and maintain orthodoxy should be avoided as it must inevitably retard the scientific goal of establishing reliable knowledge.     

On the nature of identity fusion: insights into the construct and a new measure

Previous research has documented the consequences of feeling fused with a group; here we examine the nature of identity fusion. Specifically, we sought to determine what fusion is and the mediating mechanisms that lead fused individuals to make extraordinary sacrifices for their group. Guided by the assumption that fusion emphasizes the extent to which people develop relational ties to the group, we developed a measure designed to capture feelings of connectedness and reciprocal strength with the group. In 10 studies, the newly developed scale displayed predicted relationships with related measures, including an earlier (pictorial) measure of fusion and a measure of group identification. Also as expected, fusion scores were independent of several measures of personality and identity. Moreover, the scale predicted endorsement of extreme progroup behaviors with greater fidelity than did an earlier pictorial measure of identity fusion, which was, in turn, superior to a measure of group identification. Earlier evidence that the personal and social selves of fused persons are functionally equivalent was replicated, and it was shown that feelings of agency and invulnerability mediated the effects of fusion on extreme behavior. Finally, Spanish- and English-language versions of the verbal fusion scale showed similar factor structure as well as evidence of convergent, discriminant, and predictive validity in samples of Spaniards and Americans, as well as immigrants from 22 different countries. This work advances a new perspective on the interplay between social and personal identity.     

Transformational escapes: Accessing consumer transformation through extraordinary experiences

Previous research implies that the transformational potential of extraordinary experiences arises from the engagement with the experiential context, although we still do not know how this process happens and to what extent it changes consumers. In this article, we explore the processes by which consumers transform themselves through extraordinary experiences and the characteristics of such a transformation. Based on a three-year ethnography in the context of marathon running, we identified the three processes that engender consumer transformation: the physical transformation process, the mental transformation process, and the discursive transformation process. These processes are sheltered by the transformational escape, defined as the consumption setting that integrates structural and antistructural features through the engagement of consumers' routine with the extraordinary experience, enabling consumer transformation. We extend current theorizations by revealing the dynamics that elongate extraordinary experience duration, enable the dynamic between routine and extraordinary experience, and enlarge the reach of consumer transformation.     

Haptically perceiving the distances reachable with hand-held objects

Nine experiments are reported on the ability of people to perceive the distances reachable with hand-held rods that they could wield by movements about the wrist but not see. An observed linear relation between perceived and actual reaching distances with the rods held at one end was found to be unaffected by the density of the rods, the direction relative to the body in which they were wielded, and the frequency at which they were wielded. Manipulating (a) the position of an attached weight on an otherwise uniformly dense rod and (b) where a rod was grasped revealed that perceived reaching distance was governed by the principal moment(s) of inertia (I) of the hand-rod system about the axis of rotation. This dependency on moment of inertia (I) was found to hold even when the reaching distance was limited to the length of rod extending beyond an intermediate grasp. An account is given of the haptic subsystem (hand-muscles-joints-nerves) as a smart perceptual instrument in the Runeson (1977) sense, characterizable by an operator equation in which one operator functionally diagonalizes the inertia and strain tensors. Attunement to the invariants of the inertia tensor over major physical transformations may be the defining property of the haptic subsystem. This property is discussed from the Gibsonian (ecological) perspectives of information as invariants over transformations and of intentions as extraordinary constraints on natural law.     

The development of possibility judgment within and across domains

The ability to differentiate possible events from impossible ones is an invaluable skill when reasoning about claims that transcend the perceptual evidence at hand, yet preschool-aged children do not readily make this differentiation when reasoning about physically extraordinary events [Shtulman, A., &; Carey, S. (2007). Improbable or impossible? How children reason about the possibility of extraordinary claims. Child Development, 78, 1015–1032]. The present study sought to determine whether this failure stems from deficits in domain-specific knowledge or deficits in the domain-general procedure by which possibility judgments are made. Participants (48 children aged 4-9 years olds and 16 adults) were asked to judge the possibility of three types of extraordinary events – physical, psychological, and biological – and to justify their judgments of impossibility. Developmental changes in the ability to differentiate improbable events from impossible events were qualitatively similar across domains. Moreover, participants’ propensity to judge improbable events possible was significantly correlated with the quality of their justifications, both within and across domains. These findings suggest that modal development involves a domain-general change in how modal claims are evaluated.     

Exceptional reported effects and data anomalies merit explanation from “A randomized controlled trial of coordination exercise on cognitive function in obese adolescents” by Liu et al. (2018)

We read the article in Psychology of Sport and Exercise by Liu et al. (“A randomized controlled trial of coordination exercise on cognitive function in obese adolescents”) with great interest. Our interest in the article stemmed from the extraordinary differences in obesity-related outcomes reported in response to a rope-jumping intervention. We requested the raw data from the authors to confirm the results and, after the journal editors reinforced our request, the authors graciously provided us with their data. We share our evaluation of the original data herein, which includes concerns that weight and BMI loss by the intervention appears extraordinary in both magnitude and aspects of the distributions. We request that the authors address our findings by providing explanations of the extraordinary data or correcting any errors that may have occurred in the original report, as appropriate.     

The Embodied God: Core Intuitions About Person Physicality Coexist and Interfere With Acquired Christian Beliefs About God,the Holy Spirit,and Jesus

Why are disembodied extraordinary beings like gods and spirits prevalent in past and present theologies? Under the intuitive Cartesian dualism hypothesis, this is because it is natural to conceptualize of minds as separate from bodies; under the counterintuitiveness hypothesis, this is because beliefs in minds without bodies are unnatural—such beliefs violate core knowledge intuitions about person physicality and consequently have a social transmission advantage. We report on a critical test of these contrasting hypotheses. Prior research found that among adult Christian religious adherents, intuitions about person psychology coexist and interfere with theological conceptualizations of God (e.g., infallibility). Here, we use a sentence verification paradigm where participants are asked to evaluate as true or false statements on which core knowledge intuitions about person physicality and psychology and Christian theology about God are inconsistent (true on one and false on the other) versus consistent (both true or both false). We find, as predicted by the counterintuitiveness hypothesis but not the Cartesian dualism hypothesis, that Christian religious adherents show worse performance (lower accuracy and slower response time) on statements where Christian theological doctrines about God's physicality (e.g., incorporeality, omnipresence) conflict with intuitions about person physicality. We find these effects for other extraordinary beings in Christianity—the Holy Spirit and Jesus—but not for an ordinary being (priest). We conclude that it is unintuitive to conceptualize extraordinary beings as disembodied, and that this, rather than inherent Cartesian dualism, may explain the prevalence of beliefs in such beings.     

Development and validation of a psychometric instrument for the assessment of depression in the elderly

Depression is one of the main the psychological disorders in the gerontological population. However, in many cases the depressive alterations can go unnoticed or masked by the elderly s somatic complaints; or even the depressive symptoms can be ascribe to the own aging process. Moreover, it has to be added that old patients tend not to request help to specialised mental health centres. Therefore, the correct diagnosis of the depressed elderly's emotional problems becomes into a question of extraordinary importance. In this work is presented a new specific instrument for the evaluation of depression in the elderly people which has, among other characteristics, the advantage of requiring a little time to its application and a low knowledge on psychopathology. The initial results show an extraordinary sensitivity and specificity regarding to DSM-IV-TR criteria. Nevertheless, further studies with a higher number of clinical populations are necessary to confirm and enlarge these preliminary results.     

Cognitive parallels between moral judgment and modal judgment

A central question in the study of moral psychology is how immediate intuition interacts with more thoughtful deliberation in the generation of moral judgments. The present study sheds additional light on this question by comparing adults’ judgments of moral permissibility with their judgments of physical possibility—a form of judgment that also involves the coordination of intuition and deliberation (Shtulman, Cognitive Development 24:293–309, 2009). Participants (N = 146) were asked to judge the permissibility of 16 extraordinary actions (e.g., Is it ever morally permissible for an 80-year-old woman to have sex with a 20-year-old man?) and the possibility of 16 extraordinary events (e.g., Will it ever be physically possible for humans to bring an extinct species back to life?). Their tendency to judge the extraordinary events as possible was predictive of their tendency to judge the extraordinary actions as permissible, even when controlling for disgust sensitivity. Moreover, participants’ justification and response latency patterns were correlated across domains. Taken together, these findings suggest that modal judgment and moral judgment may be linked by a common inference strategy, with some individuals focusing on why actions/events that do not occur cannot occur, and others focusing on how those same actions/events could occur.     

L’innovation radicale par la méthode de l’utilisateur extraordinaire

This article presents the extraordinary user method, which aims to stimlate radical innovation by enabling designers to rediscover functional needs associated to product use. This method draws on user centered approaches, while trying to circumvent the Innovator's dilemma, which is detrimental to radical innovation. The method consists in including extraordinary users in the very first stages of innovation process, in order to rediscover the fundamental fonctional needs the target population may have forgotten. Extraordinary users can be found among lead users, children, elderly, disabled, or non-users. This methodological proposal is illustrated with application cases from several socioeconomical sectors.     

Extraordinary consumer experiences: Why immersion and transformation cause trouble

This paper presents and discusses how consumers are transformed in and out of immersion during extraordinary, long‐lasting wilderness canoeing experiences. Based on a hermeneutic multi‐phase empirical approach, we show how extraordinary experiences can be dynamic, multifaceted, and emergent. The positive connotations of prior research are questioned as we find that consumers face various paradoxes and ambiguities throughout the various consumption phases. While a major part of research today focuses on the co‐creation efforts of consumers when they combine various on‐site resource of experiencescapes, our findings point to the importance of understanding consumer resources. The distinction held between the ordinary and the extraordinary does not hold within the present context, and we discuss how role conflicts may influence transformation and immersion during consumption of experiences.     

Frank Lloyd Wright's Fallingwater: A Case Study in Inside-the-Box Creativity

This article traces the development of Frank Lloyd Wright's Fallingwater, perhaps the most famous private dwelling in the world, as a case study in creative thinking. It has been reported that Wright conceived the house in one creative leap when he first visited the site. Wright supposedly did nothing further on the house until 9 months later, when he produced complete plans in 2 hours.This story can be taken as support for the claim that creative products come about through “outside-the-box” thinking, in which the creator goes far beyond the present to produce something completely new. However, examination of the historical record supports a model of creative thinking that assumes that creative products—even extraordinary products such as Fallingwater—come about in small steps firmly founded on the past, in this case the early work of Wright and of other architects. It is not necessary to postulate any extraordinary form of thinking to understand the development of Fallingwater. This case study thus supports others in providing evidence for the conclusion that creative thinking involves inside-the-box thinking: ordinary thought processes, operating on a rich database, bringing about extraordinary results.     

Terrorist Suspect Religious Identity and Public Support for Harsh Interrogation and Detention Practices

Does the U.S. public's support for the use of harsh interrogation and detention practices against terrorism suspects depend upon the religious identity of the alleged perpetrators? Some scholarly research indicates greater public acceptance for abridging the rights of Muslims after 9/11. This is consistent with literature suggesting that heightened perception of threat decreases popular tolerance for racial, ethnic, and religious outgroups. This study executes a survey experiment and finds respondents to be more permissive of the use of extraordinary detention practices, such as indefinite detention and denying suspects access to legal counsel and civilian criminal courts, against terror suspects identified as Muslims. Furthermore, the study reveals that respondents are significantly less likely to treat domestic, right‐wing terrorist suspects with extraordinary detention, suggesting ingroup leniency.     

The relation between stimulus function and equivalence class formation

Fifty participants were exposed to a simple discrimination-training procedure during which six S+ functions were established for six arbitrary stimuli, and S- functions were established for a further six stimuli. Following this training, each participant was exposed to one of five conditions. In the S+ condition, participants were exposed to a stimulus equivalence training and testing procedure using only the six S+ stimuli as samples and comparisons. In the S+/S- condition, participants were exposed to the same training and testing sequence as in the S+ condition, the difference being that three S+ and three S- stimuli were used as sample and comparison stimuli, with each set of three corresponding to the trained equivalence relations. In the S+/S- mixed condition, the S+ and S- stimuli were assigned to their roles as samples and comparisons in a quasi-random order. In the S- condition, all six S- stimuli were used. The no-function condition served as a control condition and employed stimuli for which no stimulus-control functions had been established. The results showed that, on average, participants required more testing trials to form equivalence relations when the stimuli involved were functionally similar rather than functionally different. Moreover, participants required more test trials to form equivalence relations when novel arbitrary stimuli, rather than functionally distinct stimuli, were used as samples and comparisons. The speed of acquisition of stimulus equivalence was also related to the number of functionally similar stimuli established before training. These findings indicate a variety of ways in which the emergence of equivalence relations is affected by the functional classes in which the relevant stimuli participate.     

Children prefer to learn from mind‐readers

Kim and Harris ( 2014 , J. Cogn. Dev.) showed that children selectively learned from an informant who produced apparently magical outcomes as compared to another informant who produced only ordinary outcomes in the domain of everyday physics. In the present study, we tested children's ability to differentiate between and selectively learn from informants who displayed either an extraordinary or an ordinary ability in the domain of everyday psychology. Prior studies have shown that children come to appreciate what is ordinarily involved in knowing the private mental states of other people. Drawing on this research, we asked whether 3‐ to 4‐ and 5‐ to 6‐year‐old children preferentially learned from an informant who knew another person's mind via either an ordinary or an extraordinary form of communication. As compared to younger children, older children were more likely to learn from the extraordinary informant. Moreover, children's ability to differentiate between the two informants was a better predictor of their learning from the extraordinary informant than age. We discuss the findings in the light of prior work on selective learning, children's ideas about prayer and their understanding of impossibility.     

The Role of Response Effort and Motion Study in Functionally Equivalent Task Designs and Alternatives

We evaluated the effects of functionally equivalent task designs and alternatives, as validated by motion study procedures, on dependent variables (nonadaptive responses, use of alternative, attempts at task, and completed attempts at task) relevant to performing a selected task. First, we evaluated the effects of functionally equivalent task designs on the dependent variables. Second, we evaluated the effects of an efficient functionally equivalent alternative on the variables. Third, we compared the effects of the efficient functionally equivalent alternative with a less efficient functionally equivalent alternative on the same variables. The results showed that the inefficient functionally equivalent task design occasioned higher rates of nonadaptive responses than the efficient functionally equivalent task design. The results also showed that the functionally equivalent task designs and alternatives competed within and across response classes to reduce nonadaptive responses. Mixed results were obtained in comparing the effects of the efficient versus the less efficient functionally equivalent alternatives. We provide evidence for extending the current concept of functional equivalence to include task design responses as well as alternative responses in functional equivalence training.     

Disruption,dialogue, and swerve: Reflective structured dialogue in religious studies classrooms

This article focuses on Reflective Structured Dialogue as a set of practices developed in the context of conflict resolution that are well suited to handling quotidian uneasiness and extraordinary moments of disruption in religious studies classrooms. After introducing Reflective Structured Dialogue's history, goals, and general practices, the authors consider its uses in classroom settings. They argue that a classroom in which teachers understand themselves as facilitators, and in which students are experienced in structured dialogue practices – including being comfortable in a state of intellectual “wobble” – is one more apt to be able to engage with, and more likely to benefit from, disruptive events.     

Associative memory and the medial temporal lobes

Associative recognition and recall depend on structures in the medial temporal lobes (MTLs). There is disagreement about whether associative memory is functionally heterogeneous, whether it is functionally distinct from intra-item associative memory and how the MTLs contribute to this kind of memory. Despite an increase in research on associative memory, work has lacked a theoretical framework to guide design and interpretation of studies. One view provides a useful framework by postulating that associative memories differ in the degree to which their informational components converge in MTL structures that create familiarity-supporting or recollection-supporting memory representations. Using this framework, we consider psychological, lesion and functional imaging evidence, highlighting how informational convergence in the brain underlies the associative nature of both memory and perception.
