The effect of adults' eating on young children's acceptance of unfamiliar foods

Adults presented unfamiliar foods to 14- to 20- and 42- to 48-month-old children individually in their homes. More children put the food in their mouths when the adults also were eating than when the adults simply were offering the food. More children put food in their mouths when their mothers were the source than when the source was a friendly adult “visitor”. However, even when alone with a child, the visitor's eating elicited reliably more tasting. Analysis of requesting behavior indicated that the adults' eating aroused a desire to eat in the children. There were no consistent sex differences or interactions between sex of visitor and sex of child in children's food acceptance. There was a suggestion that younger children were more affected by repeated offerings than were older children. It is concluded that a relatively “low level” form of observational learning—“social facilitation”—can account for the data.     

Developmental differences in intake and storage of visual information

A partial report technique was used to determine how much visual information subjects of four ages (ranging from 5-year-olds to adults) were capable of taking in and what the course of information loss was over a 1-sec time period. Subjects were tachistoscopically presented eight items followed by an indicator at variable intervals after array offset and were required to report that item in the indicated position. No reliable age differences were found at the earliest “memory point,” 50 msec. There were, however, age differences both before and after this point. Results suggested an absence of age differences in visual intake capacity, but important differences in other stages of processing.     

Social Comparison and Bystander Intervention in Emergencies

In a 2 × 2 experimental design, male subjects were exposed to a "lady in distress" in the presence of a confederate who was either similar or dissimilar to the subject and who reacted to the situation with either passive unconcern or with apparent alarm. Consistent with a social comparison interpretation, the confederate's reactions markedly influenced whether subjects intervened. While degree of similarity was unrelated to probability of occurrence of an intervention response, it exerted a strong effect on intervention response latency. It is proposed that social comparison processes not only may influence an observer's interpretation of a situation, but may also contribute to situational ambiguity and affect the observer's degree of confidence in the validity of his interpretation of the situation. Any of these factors may, in turn, determine whether and how quickly an intervention response occurs.     

There is no special problem with metaphysics

I argue for the claim in the title. Along the way, I also address an independently interesting question: what is metaphysics, anyway? I think that the typical characterizations of metaphysics are inadequate, that a better one is available, and that the better one helps explain why metaphysics is no more problematic than the rest of philosophy.     

Someone is pulling the strings: hypersensitive agency detection and belief in conspiracy theories

We hypothesised that belief in conspiracy theories would be predicted by the general tendency to attribute agency and intentionality where it is unlikely to exist. We further hypothesised that this tendency would explain the relationship between education level and belief in conspiracy theories, where lower levels of education have been found to be associated with higher conspiracy belief. In Study 1 (N = 202) participants were more likely to agree with a range of conspiracy theories if they also tended to attribute intentionality and agency to inanimate objects. As predicted, this relationship accounted for the link between education level and belief in conspiracy theories. We replicated this finding in Study 2 (N = 330), whilst taking into account beliefs in paranormal phenomena. These results suggest that education may undermine the reasoning processes and assumptions that are reflected in conspiracy belief.     

Depth of Field: Using photographs and narratives to explore and reflect on ageing

The learning landscape of the higher education environment is changing, with an increased focus over the past decade on how educators might begin to cultivate reflective skills in health professions students. In addition, changing professional requirements demand that health professionals are adequately prepared to practise in today’s complex healthcare systems, including responding to changing demographics of population ageing. In this educational case study, we will share how we (a group of education, medical and nursing academics) developed ‘Depth of Field: Exploring Ageing’ a digital, consumer-driven, interprofessional reflective learning resource that uses photographs, narrative and small-group work to strengthen reflective capacity in current and/or future health professionals.     

Cognitive Load Differentially Impacts Response Control in Girls and Boys with ADHD

Children with attention-deficit hyperactivity disorder (ADHD) consistently show impaired response control, including deficits in response inhibition and increased intrasubject variability (ISV) compared to typically-developing (TD) children. However, significantly less research has examined factors that may influence response control in individuals with ADHD, such as task or participant characteristics. The current study extends the literature by examining the impact of increasing cognitive demands on response control in a large sample of 81children with ADHD (40 girls) and 100 TD children (47 girls), ages 8–12 years. Participants completed a simple Go/No-Go (GNG) task with minimal cognitive demands, and a complex GNG task with increased cognitive load. Results showed that increasing cognitive load differentially impacted response control (commission error rate and tau, an ex-Gaussian measure of ISV) for girls, but not boys, with ADHD compared to same-sex TD children. Specifically, a sexually dimorphic pattern emerged such that boys with ADHD demonstrated higher commission error rate and tau on both the simple and complex GNG tasks as compared to TD boys, whereas girls with ADHD did not differ from TD girls on the simple GNG task, but showed higher commission error rate and tau on the complex GNG task. These findings suggest that task complexity influences response control in children with ADHD in a sexually dimorphic manner. The findings have substantive implications for the pathophysiology of ADHD in boys versus girls with ADHD.
