Individual differences in 10‐month‐olds' performance on the A‐not‐B task

This study used the classical A‐not‐B task (Piaget, 1954 ) to explore individual differences in cognitive flexibility in 10‐month‐old infants by: (1) examining how differences in search performance during A trials relate to search performance during B trials; (2) studying the relation between temperamental dimensions and A‐not‐B performance; and (3) investigating differences in search performance between looking and reaching responses within the same task. Forty infants were tested on a fixed‐design‐version of the A‐not‐B task, not allowing for training or individual adjustment, but instead eliciting additional search behaviors than the common correct responses in A trials and perseverative errors in B trials. Infants were also rated by their parents on the temperamental scales Activity level and Attention span. The main findings were: (1) performance on A trials affected B trial performance, with infants being more correct on A trials having more incorrect and less ‘no search’ responses on B trials; (2) activity level, but not attention span, was related to performance on the A‐not‐B task, with infants performing better on A trials having a lower activity level; and (3) there were a few differences in performance with regard to modality, indicating that responding correctly by looking may be less cognitively demanding than doing so by reaching. This study demonstrated that 10‐month‐olds show a wide variation of search behaviors on this A‐not‐B task, resulting in individual differences in performance. These differences are suggested to reflect variation in temperamental activity level as well as maturity of short term/working memory, inhibition and cognitive flexibility.     

A qualitative study of citizens' experience of participating in health counseling

Individual health counseling is a form of intervention designed to minimize the effects of chronic health disease and to offer a path towards good health practices. The aim of the present study was to explore the experiences of those persons who participated in health counseling in order to assess the psychosocial significance of the counseling upon their health behavior. In addition the study was concerned with the factors which underlay peoples' decision to sign up for health counseling. The research involved 11 semi‐structured interviews with individuals who had participated in a municipality based health counseling program. Data was analyzed using Malterud's systemic text condensation and a theoretical framework around Bandura's social cognitive theory. Analysis revealed that an approach tailored to each individual with minor short‐term goals accompanied by feeling supported by the counselor produced the greatest impact on behavior. Receiving feedback from the counselor and feeling positive about the relationship were seen as essential. These aspects were also crucial in the decision to undertake health counseling. The study indicates that whether individual's sign up on their own initiative or conversely are invited to join the program has no influence upon their motivation to change their behavior. Overall the respondents demonstrated improvement in their behavior and attitudes towards their health. However, the study also indicates that this form of intervention is less or even ineffective without the support of the individual's immediate family.     

Anxiety and speaking in people who stutter: An investigation using the emotional Stroop task

People with anxiety disorders show an attentional bias towards threat or negative emotion words. This exploratory study examined whether people who stutter (PWS), who can be anxious when speaking, show similar bias and whether reactions to threat words also influence speech motor planning and execution. Comparisons were made between 31 PWS and 31 fluent controls in a modified emotional Stroop task where, depending on a visual cue, participants named the colour of threat and neutral words at either a normal or fast articulation rate. In a manual version of the same task participants pressed the corresponding colour button with either a long or short duration. PWS but not controls were slower to respond to threat words than neutral words, however, this emotionality effect was only evident for verbal responding. Emotionality did not interact with speech rate, but the size of the emotionality effect among PWS did correlate with frequency of stuttering. Results suggest PWS show an attentional bias to threat words similar to that found in people with anxiety disorder. In addition, this bias appears to be contingent on engaging the speech production system as a response modality. No evidence was found to indicate that emotional reactivity during the Stroop task constrains or destabilises, perhaps via arousal mechanisms, speech motor adjustment or execution for PWS.Educational objectives: The reader will be able to: (1) explain the importance of cognitive aspects of anxiety, such as attentional biases, in the possible cause and/or maintenance of anxiety in people who stutter, (2) explain how the emotional Stroop task can be used as a measure of attentional bias to threat information, and (3) evaluate the findings with respect to the relationship between attentional bias to threat information and speech production in people who stutter.     

RELIGION IS EASY,BUT SCIENCE IS HARD … UNDERSTANDING McCAULEY'S THESIS

Robert N. McCauley's new book Why Religion Is Natural and Science Is Not (2011) presents a new paradigm for investigating the relationship between science and religion by exploring the cognitive foundations of religious belief and scientific knowledge. McCauley's contention is that many of the differences and disagreements regarding religion and science are the product of distinct features of human cognition that process these two domains of knowledge very differently. McCauley's thesis provides valuable insights into this relationship while not necessarily leading to a dismissive view of theology or religious belief. His paradigm allows the research lens to focus on cognitive differences in processing scientific versus religious information and the important role of automatic, unconscious, and intuitive cognitive processes in understanding both the natural and supernatural worlds.     

DEFINING “RELIGION” AS NATURAL: A CRITICAL INVITATION TO ROBERT McCAULEY

Previous critics have argued that Robert McCauley defines religion and science selectively and arbitrarily, cutting them to fit his model in Why Religion Is Natural and Science Is Not. McCauley has responded that final definitions are “overrated” and that artificial distinctions can serve an important role in naturalistic investigation. I agree with this position but argue that a genealogy of the category of religion is crucial to the methodology that McCauley describes. Since the inherent ambiguity of religion will undermine any essential claims about its cognitive naturalness, I invite McCauley to consider how his research might investigate scientific and religious cognition in new terms.     

EXPLANATORY MODESTY

Although I certainly have differences with some of my commentators, I am grateful for the time, effort, and attention that each has devoted to my book, Why Religion Is Natural and Science Is Not. They have helpfully pointed out features of my positions that need clarification and elaboration. I am also grateful to the editor of Zygon, Willem Drees, for this opportunity to undertake that task here.     

组织型插图对不同认知方式个体说明性文本阅读的影响

采用图文相继呈现、文本逐句阅读的范式,通过反应时技术与出声思维的方法考察了组织型插图对不同认知方式个体说明性文本阅读过程与阅读结果的影响,结果发现,与单一文本相比,场独立个体在有插图条件下的阅读成绩显著提高,而阅读时间没有增加,并产生了更多的推理、细化和提问策略;而场依存个体在有插图条件下的阅读成绩显著提高,阅读时间也显著增多,而理解策略没有变化。这说明组织型插图对两种认知方式个体说明性文本的阅读均起到促进作用,但场独立个体没有因为增加组织型插图而付出更多的加工努力,而是通过调整理解策略的方式来提高阅读效果;而场依存个体在阅读过程中没有根据组织型插图调整理解策略,阅读效果的提高是以付出更多的加工努力为代价的。     

On the Decision to Explore New Alternatives: The Coexistence of Under‐ and Over‐exploration

The decision whether to explore new alternatives or to choose from familiar ones is implicit in many of our daily activities. How is this decision made? When will deviation from optimal exploration be observed? The current paper examines exploration decisions in the context of a multi‐alternative “decisions from experience” task. In each trial, participants could choose a familiar option (the status quo) or a new alternative (risky exploration). The observed exploration rates were more sensitive to the frequent outcome from choosing new alternatives than to the average outcome. That is, the implicit decision whether to explore a new alternative reflects underweighting of rare events: Over‐exploration was documented in “Rare Disasters” environments, and insufficient exploration was evident in “Rare Treasures” environments. In addition, the results reveal a decrease in exploration of new alternatives over time even when it is always optimal and some exploration even when it is never reinforcing. These results can be captured with models that share a distinction between “data collection” and “outcome‐driven” decision modes. Under the data collection mode, the decision maker collects information about the environment, to be used in future choices. Under the outcome‐driven mode, the decision maker relies on small samples of previous experiences with familiar versus unfamiliar alternatives, before the selection of a specific alternative. The predictive value of a two‐parameter “explorative sampler” quantification of these assumptions is demonstrated. Copyright © 2013 John Wiley & Sons, Ltd.     

Malleability of weight-biased attitudes and beliefs: A meta-analysis of weight bias reduction interventions

Weight bias exists across many important life domains, necessitating interventions designed to reduce weight-biased attitudes and beliefs. Though the effectiveness of weight bias interventions has been questioned, to our knowledge no meta-analysis of these interventions has been conducted. This meta-analysis evaluated the impact of weight bias interventions on weight-biased attitudes and beliefs and explored potential moderators. Interventions were eligible if they used an adult sample and a validated measure of weight-biased attitudes, which resulted in the inclusion of 30 studies represented in 29 articles. A random effects approach using inverse weights resulted in a mean effect size estimate of g = −0.33 (lower scores indicate less weight bias) for both attitudes and beliefs. Intervention type, publication type, and population type were not significant moderators but demonstrated noteworthy trends. Results reveal a small, positive effect of weight bias interventions on weight-biased attitudes and beliefs and provide useful information for future interventions.
