Categorization in compulsive hoarding

Based on hypothesizing about the role of information processing, and in particular, underinclusive categorization in compulsive hoarding, this study examined categorization processes in people with clinically significant compulsive hoarding problems. Twenty-one participants with primary compulsive hoarding, 21 with OCD without hoarding, and 21 non-psychiatric controls completed three categorization tasks. Hoarding and OCD participants reported significantly more distress prior to each of the three tasks than did controls. On tasks sorting common household items, the groups did not differ on the number of piles created nor on the amount of time taken to sort. However, on a task sorting personally relevant items, hoarding participants took more time, created more piles, and reported more anxiety than non-psychiatric controls. Hoarders also took more time than the OCD group, and tended to create more piles. Hoarding severity was correlated with the number of piles created, but only when the objects were personally relevant. Results support under-inclusive categorizing for people with compulsive hoarding, but the effect was largely confined to objects of personal relevance.     

Family Interactions in Children With and Without ADHD

We used global ratings to compare the family (parent[s]-child) interactions of 51 clinic-referred children with ADHD and 32 non problem children. Children and parent(s) were videotaped while engaging in problem solving and game playing activities. Independent coders, blind to children's diagnostic status, rated the interactions using measures designed to assess interaction competence and quality. Significant group differences emerged between the ADHD and control groups during problem solving on the interaction quality measures of Warmth, Engagement and Communication. Comparisons of the interactions of families of children with ADHD, with (ADHD W) and without (ADHD W/O) comorbid disruptive behavior disorders, were non significant, although increased symptomology was associated with reduced Warmth and Engagement during problem solving. Irrespective of group membership family interactions were more positive during game playing versus problem solving.     

Social Support Mediates Loneliness and Human Herpesvirus Type 6 (HHV-6) Antibody Titers

The current study investigated the impact of a severe environmental stressor and the role that declining social integration played in mediating its effect on loneliness and immune status. Increased loneliness and decreased social support in the months following the stressor (storm) were significantly associated with increased HHV-6 antibody liters, reflecting poorer control over the virus. Poorer social integration mediated the relationship between loneliness and HHV-6, even after controlling for nonspecific polyclonal B-cell activation, disease status (CD3+CD4+ cell counts), living arrangements, acute social losses (bereavement), and potential disruptions in social-support resources. These findings suggest that specific elements of social support may explain the oft-noted negative effects of loneliness on the immune system, and generalized to a medically vulnerable population.     

Developmental and Sex Differences in Types of Conduct Problems

Maternal report of types of conduct problems in a high-risk sample of 228 boys and 80 girls (ages 4–18) were examined, using a version of the Child Behavior Checklist, expanded to include a range of covert and overt antisocial items (stealing, lying, physical aggression, relational aggression, substance use, and impulsivity). Age and sex effects were investigated. Boys were significantly more physically aggressive than girls. There were no sex differences for stealing, lying, relational aggression, and substance use. Lying and substance use increased with age, whereas relational aggression and impulsivity peaked during early adolescence. A small group of girls had pervasive conduct problems across multiple domains. For some domains such as stealing, lying, and relational aggression, girls showed at least as many problems as boys. Girls, in general, tended to have fewer conduct problems. On the other hand, when assessed across multiple domains, conduct problems in high-risk girls were possibly more pervasive than in high-risk boys, suggesting the possibility of a gender paradox.     

Unconscious fantasy in context: The work of Jacob A. Arlow

For Jacob A. Arlow, understanding unconscious fantasies was central to his clinical work. These fantasies are to be found at the core of those eruptions that break without warning into our ordinary lives, whether in the form of hysterical symptoms, daydreams or nightmares. What, however, could an unconscious fantasy be on a theoretical level, beyond a vehicle for discharge? Although partly unconscious, such fantasies are sometimes composed of fixed verbal content with a high degree of internal organisation. Unconscious fantasies therefore pose many challenges to understanding.     

Empathy's Relation to Appraisal of the Emotional Child Witness

When observing others, we often try to determine how they ‘really feel’ deep down inside (emotional feeling) regardless of their outward expression (emotional appearance). We examined whether child victim empathy predicts appraisal of a child sexual assault victim's emotional feelings and, in turn, child and defendant believability and verdict decisions. Undergraduates (N = 50) rated photographs of 5‐ and 13‐year‐olds' degree of sadness. Then, a new group of undergraduates (N = 354), randomly assigned within a 2 (victim age) × 2 (victim gender) × 3 (victim sadness: low, medium, and high/teary) factorial design, read trial scenarios accompanied by one of the photographs. Participants rated the victim's emotional feeling and emotional appearance, victim and defendant believability, defendant guilt, and confidence in their verdict. A structural equation model that included a relation between empathy and emotion appraisal fit the data well: Empathy predicted appraisal of the victim's feelings, which, in turn, predicted perceived believability. Implications are discussed.Copyright © 2017 John Wiley & Sons, Ltd.     

God-mediated control beliefs and the Epstein-Barr virus: Is more God-mediated control always better?

Research on the locus of control construct conveys the impression that more control is always better. However, some studies suggest that very high levels of control are associated with negative outcomes. The purpose of this study was to see if this is true of religiously oriented feelings of control (i.e., God-mediated control). The outcome was antibody titers to the Epstein-Barr virus (EBV). The findings suggest that very high God-mediated control is associated with higher EBV values. However, this finding was only observed among young adults (age 18–40), but not among middle-aged (age 41–64), or older adults (aged 65 and older).     

A day of great illumination: B. F. Skinner's discovery of shaping

Despite the seminal studies of response differentiation by the method of successive approximation detailed in chapter 8 of The Behavior of Organisms (1938), B. F. Skinner never actually shaped an operant response by hand until a memorable incident of startling serendipity on the top floor of a flour mill in Minneapolis in 1943. That occasion appears to have been a genuine eureka experience for Skinner, causing him to appreciate as never before the significance of reinforcement mediated by biological connections with the animate social environment, as opposed to purely mechanical connections with the inanimate physical environment. This insight stimulated him to coin a new term (shaping), and also led directly to a shift in his perspective on verbal behavior from an emphasis on antecedents and molecular topographical details to an emphasis on consequences and more molar, functional properties in which the social dyad inherent to the shaping process became the definitive property of verbal behavior. Moreover, the insight seems to have emboldened Skinner to explore the greater implications of his behaviorism for human behavior writ large, an enterprise that characterized the bulk of his post-World War II scholarship.
