Contingency judgements on the fly

The present research was conducted to establish the validity of a novel procedure for measuring human contingency judgements aimed at shortening the length of conventional procedures. Cues and outcomes were simple geometric shapes that were presented in a rapid streaming fashion, reducing the length of a block of trials from several minutes to a few seconds. We establish the reliability of the procedure by replicating two central findings in the contingency judgement literature, and we elaborate on the importance of this method for future research.     

Children's attention to beliefs in interactive persuasion tasks

Whether and when children can apply their developing understanding of belief to persuasion was examined using interactive puppet tasks. Children selected 1 of 2 arguments to persuade a puppet to do something (e.g., pet a dog) after hearing the puppet's belief (e.g., "I think puppies bite"). Across 2 studies, 132 children (ages 3-7 years) engaged in these persuasion tasks and in false-belief reasoning tasks, presented in puppet and story formats. Belief-relevant argument selection increased with age, as did appropriate reasoning about false beliefs, and occurred more in puppet than story tasks. Results suggest that improvements in belief reasoning in early childhood may be reflected in social interactions such as persuasion.     

Sex differences in the activity level of infants1

A gender difference in motor activity level (AL) is well established for children, but questions about the existence and nature of an infant sex difference remain. To assess these questions, we applied meta‐analytic procedures to summarize 46 infancy studies comprising 78 male–female motor activity comparisons. Our results showed that, as with children, male infants were more active than females. Objective measures of infant AL estimated the size of this difference to be 0.2 standard deviations, though subjective parent‐report measures estimated the difference to be smaller. We argue that this early sex difference in activity level is biologically based. However, socialization processes, such as gender‐differentiated expectations and experiences, in conjunction with further sex‐differentiated biological developments, amplify this early difference to produce the larger gender differences in activity found during childhood.

The relationship between bullying, psychotic-like experiences and appraisals in 14-16-year olds

The psychological consequences of bullying have been the focus of much research over the last 25 years. However, the relationship between bullying and psychotic experiences has been relatively ignored despite the weight of evidence which suggests that traumatic events in childhood are significantly related to psychotic disorders. 373 pupils aged between 14 and 16 years took part in the study. They were asked to complete a number of self-report measures which examined their experience of bullying, predisposition to auditory hallucinations, paranoia and dissociation, and beliefs about both the self and the world and about paranoia. It was found that bullying was significantly associated with predisposition to psychotic experiences. Negative post-trauma cognitions were also associated with predisposition to psychotic phenomena as were positive beliefs about paranoia. Being bullied at school and beliefs about trauma and psychotic symptoms may contribute to the development of psychosis. However, it is also possible that these results indicate that experiencing psychotic-like phenomena increases the likelihood that a pupil's interpersonal context is characterised by peer hostility and rejection. The implications of these results are discussed.     

Granny, (don't) get your gun: competency issues in gun ownership by older adults

This article explores the possible risks associated with gun ownership by older adults. We summarize existing regulations on who may own firearms, especially with respect to age. We then present data on older gun owners and violence committed by older adults in general, followed by a discussion of gun violence perpetrated by gun owners whose functional and cognitive abilities have declined, perhaps as a result of dementia. For comparison purposes, we review regulations on driving among older adults, drawing parallels to gun ownership. The paper concludes with recommendations for ensuring the safety of older gun owners and others, balanced against citizens' right to bear arms, and with some directions for research.     

EEG characteristics prior to and following the evoked K-Complex.

This study was designed to determine if the K-Complex reflects an arousal from sleep or a sleep protection mechanism. Ten participants were presented auditory stimuli every 20 s while asleep. Trials were sorted according to the presence or absence of a K-Complex. A fast Fourier Transformation of the data was computed on EEG segments prior to and following stimulus onset. The log power of activity in delta, theta, alpha, sigma, and beta bandwidths was computed. When a K-Complex was elicited, there were no differences in EEG activity prior to and following the stimulus. However, during slow wave sleep, when a K-Complex was not elicited, there was a significant overall increase in theta, alpha, sigma, and beta activity following stimulus. These results tend to support the notion that the K-Complex appears to prevent arousal.     

Who Deserves Faulty Products? How Blaming the Victim Prevents Consumer Punitive Action

A core requirement of a functioning free‐market system is that consumers hold companies accountable for selling faulty products. Following a harmful product failure, any blame that is incorrectly directed toward the victim may threaten consumer well‐being. Four experiments—in contexts of both fictitious and actual high‐profile product failures—show that this may in fact occur. The findings show that for a victim possessing immoral character: (a) consumers exaggerate blame because, (b) the victim is seen as deserving of suffering in general and, as a result, (c) consumers are less likely to take punitive action against the company (e.g., petition signing, negative word of mouth, and supporting financial justice). One field experiment and three online experiments converge to show that morality's effects are unique from other traits (e.g., sociability), but may be attenuated based on severity of harm to the victim and consumers’ own beliefs about justice. In sum, the current research furthers understanding of how and why victims are blamed, how doing so may threaten consumer and societal well‐being, and how it might be prevented.     

Parenting after Weight Loss Surgery: A Conceptual Model and Two Case Reports

The ways families approach eating, shape, and weight can result in stress for individual family members and challenge the overall functioning of the family. This is further complicated among families with a parent who has history of obesity or undergone weight loss surgery (WLS). Although WLS can positively impact other family members, it can also exacerbate conflicts regarding feeding and weight. Such conflicts can involve uncertainty regarding the extent to which the entire family should make the dietary changes recommended for the post-WLS parent. Conflict might also center on the appropriate level of concern regarding the children’s risk of developing (or maintaining) obesity. This paper uses two case examples to describe the application of a specialized, time-limited intervention: Parent-Based Prevention following Bariatric Surgery (PBP-B). The program was developed to address the unique challenges and concerns that arise after, or are exacerbated by, WLS. Each detailed case example illustrates a common child-feeding challenge and the employment of key PBP-B strategies throughout the course of treatment. In the first case, the parent who had undergone WLS believed the family’s current eating behaviors were the same as those that had led to her own overeating, obesity, and co-occurring psychiatric symptoms, while her husband disagreed. In the second case, both parents were concerned about their son’s weight, yet due to their prior eating histories, they felt unable to construct boundaries around the feeding experience. Both cases follow families through the entire intervention and illustrate key points and challenges. These cases underscore the need for novel treatment modalities to support families following parental WLS.     

Counselor Empathy; Religiosity; and Lesbian,Gay, and Bisexual Perspectives

Values-based conflicts, such as between counselor religiosity and ability to work with lesbian, gay, and bisexual (LGB) clients, can present a challenge for counselors and trainees who seek to provide ethical and competent care. Because empathy can facilitate understanding a client's frame of reference, the authors examined the relationships between counselor religiosity, empathy, and LGB perspectives, as well as the potential mediating effects of empathy on values conflicts. The authors discuss implications for counselor education and practice.
