The stress-eating paradox: Multiple daily measurements in adult males and females

Abstract

The stress-eating relationship was examined in a prospective study of 158 subjects who completed daily records of stress and eating for 84 days, yielding 16.188 person days of observation. Using both within-subjects and between-subjects analyses, individuals were much more likely to eat less than usual than to eat more than usual in response to stressful daily problems. The likelihood of eating more did not change as severity of stress increased, but the likelihood of eating less increased substantially. There were also clear gender differences. Males had a slight tendency to eat less than to eat more across all levels of stress, except at the highest level, where eating less occurred much more frequently. In females, the tendency to eat less as opposed to eating more emerged at middle levels of stress; at the highest level of stress, females were more than three times more likely to eat less than to eat more. Individual subjects were highly consistent over levels of stress in the direction of eating; 82% of the subjects were consistent in eating more or less over the majority of their stressful periods. These results show a clear effect of stress on eating, with eating less being the predominant response.     

Examining the effects of perceived social support on momentary mood and symptom reports in asthma and arthritis patients

Objective: Social support has been linked to beneficial effects on health directly (main effect) and as a buffer to stress. Most research, however, has examined these relationships using global and retrospective assessments of health and stress, which may be subject to recall biases. This study used ambulatory ecological momentary assessment (EMA) methods to test the main and stress-buffering effects of social support on the daily health and well-being of asthma and rheumatoid arthritis (RA) patients.

Design: Community volunteers with asthma (n?=?97) or RA (n?=?31) responded to EMA prompts five times daily for one week.

Main outcomes: Baseline perceived social support was obtained, and then, participants reported mood, stress and symptoms using EMA. Multilevel mixed-modelling examined whether social support predicted mood and symptoms directly or via stress-reducing effects.

Results: Supporting a main effect, more perceived social support predicted decreased negative mood and stress severity. Supporting a stress-buffering effect, more perceived social support resulted in fewer reported symptoms when stress was present.

Conclusion: Results suggest perceived social support directly relates to better ambulatory status and dynamically buffers individuals against the negative effects of stressors, and highlight the importance of studying social support across different temporal and contextual levels.     

Autism characteristics in children with fetal alcohol spectrum disorders

Background: Children with fetal alcohol spectrum disorders (FASD) exhibit difficulties in many cognitive and behavioral domains and also have high comorbidity with other disorders such as attention deficit/hyperactivity disorder (ADHD) and conduct disorder as well as autism. Although the FASD profile is shown to be distinct from ADHD and conduct disorder, far less is known about the commonalities with autism. The current study used a parent-rated questionnaire containing an autism subscale to explore the autistic-like features that children with FASD exhibit. Methods: Studied were 25 children with FASD (age: M = 10.3 years) and 17 normal controls (NCs; age: M = 10.2 years). As part of a larger study, all parents/caregivers completed the Social Skills Improvement System (SSIS; Gresham & Elliot, 2008), which in addition to evaluating social skills and behavior problems globally, includes an Autism subscale. Results: Between-group comparisons showed the FASD group not only scored significantly lower in social skills and significantly higher in behavior problems than the NC group but children with FASD also scored significantly higher on the Autism subscale. Item analysis revealed they showed the most difficulty in terms of social and communicative functioning and the least in repetitive and restrictive behaviors. Conclusion: Current findings signify that FASD and autism share similarities with regard to social and communicative functioning. These findings, which further our knowledge of the FASD phenotype, may be useful in specifying the particular interventions these children need.     

Intrinsicality for Monists (and Pluralists)

Two competing views in sparse ontology are monism and pluralism. In Trogdon 2009 I propose an account of intrinsicality that I argue is both compatible with monism and pluralism and independently plausible. Skiles 2009 argues that my account fails on both fronts. In this note I respond to his two objections.     

Autism spectrum conditions among children and adolescents: A new profiling tool

There is considerable debate about the sociocognitive features of autism spectrum conditions (ASC), and a tool for profiling the sociocognitive profiles of children and adolescents with ASC is needed. The aim of this research was to evaluate the psychometric properties of a new questionnaire—The Australian Scale for Autism Spectrum Conditions (ASASC). Three hundred twenty‐two parents of children on the ASC spectrum, including autistic disorder (n = 76), Asperger's disorder (n = 188), and pervasive developmental disorder not otherwise specified (n = 21), and a clinical group of children with subclinical ASC features and no ASC diagnosis (n = 37). Measures include an initial scale measuring eight potential dimensions of ASC, a related screening tool for autism, and two previously validated social skills questionnaires. The questionnaires were administered online. The ASASC was factor‐analysed, internal and test–retest reliabilities (for a randomly selected 84 parents) were calculated, and preliminary tests of convergent and divergent validity were conducted. The resulting measure (44 items) contained five coherent and reliable dimensions: understand and express emotion, fact orientation, sensory sensitivity, social communication, and rigidity. The questionnaire had good test–retest reliability and convergent/divergent validity. The ASASC enables profiles of ASC symptomatology that should be useful in adjusting interventions to individual needs.     

Solving small spaces: investigating the use of landmark cues in brown capuchins (Cebus apella)

Some researchers have recently argued that humans may be unusual among primates in preferring to use landmark information when reasoning about some kinds of spatial problems. Some have explained this phenomenon by positing that our species’ tendency to prefer landmarks stems from a human-unique trait: language. Here, we test this hypothesis—that preferring to use landmarks to solve such tasks is related to language ability—by exploring landmark use in a spatial task in one non-human primate, the brown capuchin monkey (Cebus apella). We presented our subjects with the rotational displacement task, in which subjects attempt to relocate a reward hidden within an array of hiding locations which are subsequently rotated to a new position. Over several experiments, we varied the availability and the salience of a landmark cue within the array. Specifically, we varied (1) visual access to the array during rotation, (2) the type of landmark, (3) the consistency of the landmark qualities, and (4) the amount of exposure to the landmark. Across Experiments 1 through 4, capuchins did not successfully use landmarks cues, suggesting that non-linguistic primates may not spontaneously use landmarks to solve some spatial problems, as in this case of a small-scale dynamic spatial task. Importantly, we also observed that capuchins demonstrated some capacity to learn to use landmarks in Experiment 4, suggesting that non-linguistic creatures may be able to use some landmarks cues in similar spatial tasks with extensive training.     

Switching strategies: a dolphin’s use of passive and active acoustics to imitate motor actions

Scientists have long debated the extent to which animals can imitate. Observations of bottlenose dolphins suggest a sophisticated capacity for social imitation, but little is known about the nature of these abilities. Here, we explore the behavioral mechanisms underlying a dolphin’s ability to copy motor actions while blindfolded (i.e., wearing eyecups). When a dolphin was asked to imitate a dolphin, a human, and then another dolphin blindfolded, his accuracy remained relatively consistent across models. However, his blindfolded echolocation dramatically increased when copying a human as compared to other dolphins, suggesting he actively switched between strategies: recognizing behaviors via characteristic sounds when possible, but via echolocation for the more novel sounding behaviors of the human. Such flexibility in changing perceptual routes demonstrates that the dolphin’s imitation was not automatically elicited, but rather results from an intentional, problem-solving approach to imitation.     

“Too Asian?” or the Invisible Citizen on the Other Side of the Nation?

In November 2010, Maclean’s magazine published a provocative article “Too Asian?” which aroused hot debate and critique from various social groups. However, its racist nature and the role of media in reinforcing racial stereotypes, manufacturing consent, and naturalizing unequal power relations has not been examined in a systematic way. Using critical discourse analysis, this paper aims to reveal its ideological and hegemonic function in constructing unequal social identities and social relations which consequently prevents racialized minorities from accessing post-secondary educational opportunities. Four themes are identified and discussed here. First, the “Too Asian?” article reinforces an Us/Them division and a “forever foreigner” identity of racialized minorities. Second, it essentializes ethnic culture and identifies culture rather than structural constraints as an explanation for individual social behaviors. Third, it represents “Asian” students as self-segregationists who should be blamed for their own exclusion. Last, but most important, it aims to justify white privilege in the field of post-secondary education by questioning the idea of meritocracy as university admission criteria and suggests maintaining “WASP Credentials.”     

Assessment of dispositional embarrassability

Abstract

Embarrassability, the propensity for an individual to experience embarrassment, has been frequently acknowledged as an important personality characteristic. The present research sought to explore the dispositional features of embarrassability by the psychometric development of 25-item measure, the Susceptibility to Embarrassment Scale (SES). The SES was designed to describe the personality characteristics of easily embarrassed persons rather than reactions to potentially embarrassing situations. The results indicated that the SES was an internally consistent and temporally stable measure. Its items were uncontaminated by social desirability. Assessments of construct validity suggested that the scale was a valid measure of embarrassability, and specifically a better measure of dispositional components of embarrassability than the only alternative measure of the construct. The location of the SES within the Big Five structure of normal adult personality is presented as well as its relationship with measures of deviant personality.     

Cognitive reappraisal and secondary control coping: associations with working memory,positive and negative affect,and symptoms of anxiety/depression

Abstract

The current study examined the relations of measures of cognitive reappraisal and secondary control coping with working memory abilities, positive and negative affect, and symptoms of anxiety and depression in young adults (N=124). Results indicate significant relations between working memory abilities and reports of secondary control coping and between reports of secondary control coping and cognitive reappraisal. Associations were also found between measures of secondary control coping and cognitive reappraisal and positive and negative affect and symptoms of depression and anxiety. Further, the findings suggest that reports of cognitive reappraisal may be more strongly predictive of positive affect whereas secondary control coping may be more strongly predictive of negative affect and symptoms of depression and anxiety. Overall, the results suggest that current measures of secondary control coping and cognitive reappraisal capture related but distinct constructs and suggest that the assessment of working memory may be more strongly related to secondary control coping in predicting individual differences in distress.
