A seven year follow-up of treating rumination with dietary satiation

”Fred“, a man with profound mental retardation who was 24 years old at the beginning of this study, was referred for treatment of rumination. A number of minimally restrictive interventions, including administration of Zantac, extra fluids, and delivery of peanut butter after meals, had been used without success. In April of 1989 Fred began a satiation diet with ad libitum access to starchy foods or to fruits and vegetables, in addition to his regular meals. His baseline weight was 82 pounds and he ruminated during 58% of 10 s intervals measured during 20 min post-meal observations. During the first month of the satiation diet, Fred's ruminating declined to 6% of measured intervals, he consumed a mean of 163 fluid ounces of extra food per day, and his weight increased to 90 pounds. After 4 months' treatment, Fred's ruminating had declined to zero, his food consumption had stabilized at approximately 65 extra ounces of food per day, and his weight had stabilized at about 120 pounds. Starting in August 1990, in an effort to minimize weight gain, extra food was limited to 50% of Fred's ad libitum food consumption (averaged over the previous 6 weeks). Fred's weight gradually declined to about 100 pounds with zero rumination over the next two years. In August 1992 Fred's ruminating accelerated to 17% of intervals and he was again offered ad libitum food access. Over the next 7 months, rumination declined to zero and his weight increased slightly to about 105 pounds. This study shows that rumination that had not responded to less restrictive procedures was suppressed for 7 years via dietary satiation. Although dietary satiation is not without some risk, Fred has suffered no adverse effects from the procedure, other than gaining approximately one-third of his baseline weight. © 1997 John Wiley & Sons, Ltd.     

Toward Developing Laboratory-Based Parent–Adolescent Conflict Discussion Tasks that Consistently Elicit Adolescent Conflict-Related Stress Responses: Support from Physiology and Observed Behavior

Parent–adolescent conflict poses risk for youth maladjustment. One potential mechanism of this risk is that stress in the form of increased arousal during conflict interactions results in adolescents’ impaired decision-making. However, eliciting consistent adolescent stress responses within laboratory-based tasks of parent–adolescent conflict (i.e., conflict discussion tasks) is hindered by task design. This limitation may stem from how conflict topics are assessed and selected for discussion. Within a sample of 47 adolescents (ages 14–17) and parents, we investigated whether a modified version of a conflict discussion task could elicit physiological (i.e., arousal) and behavioral (i.e., hostility) displays of adolescents’ conflict-related stress responses. We assessed parent–adolescent conflict via structured interview to identify topics for dyads to discuss during the task. We randomly assigned dyads to complete a 5-min task to discuss either a putatively benign topic (i.e., control condition) or a conflict topic while undergoing direct assessments of continuous arousal. Trained raters coded dyad members’ hostile behavior during the task. Adolescents in the conflict condition exhibited significantly greater levels of arousal than adolescents in the control condition. We observed an interaction between discussion condition and baseline conflict. Specifically, higher baseline conflict predicted greater hostile behavior for adolescents in the conflict condition, yet we observed the inverse relation for adolescents in the control condition. Our modified laboratory discussion task successfully elicited both physiological and behavioral displays of adolescent conflict-related stress. These findings have important implications for leveraging experimental paradigms to understand causal links between parent–adolescent conflict and adolescent psychopathology, and their underlying mechanisms.     

Evaluating Effort: Influences of Evaluation Mode on Judgments of Task‐specific Efforts

The claim that humans adapt their actions in ways that avoid effortful processing (whether cognitive or physical) is a staple of various theories of human behavior. Although much work has been carried out focusing on the determinants of such behaviors, less attention has been given to how individuals evaluate effort. In the current set of experiments, we utilized the general evaluability theory to examine the evaluability of effort by examining subjective value functions across different evaluation modes. Individuals judged the anticipated effort of four task‐specific efforts indexed by stimulus rotation, items to be remembered, weight to be lifted, and stimulus degradation across joint (i.e., judged comparatively) and single evaluation modes (i.e., judged in isolation). General evaluability theory hypothesizes that highly evaluable attributes should be consistently evaluated (i.e., demonstrate similar subjective value functions) between the two modes. Across six experiments, we demonstrate that the perceived effort associated with items to be remembered, weight to be lifted, and stimulus degradation can be considered relatively evaluable, while the effort associated with stimulus rotation may be relatively inevaluable. Results are discussed within the context of subjective evaluation, internal reference information, and strategy selection. In addition, methodological implications of evaluation modes are considered.

The relationship between parental racial attitudes and children’s implicit prejudice

Although many researchers assume that implicit racial attitudes develop via exposure to prejudicial socializing agents (e.g., parents, peers, and the media) starting in childhood, there is a dearth of research on implicit attitudes in children. This study looks at the effect of one socializing agent—parents—on children’s or implicit racial prejudice. Specifically, we examine Allport’s (1954) contention that children’s identification with their parents moderates the intergenerational transmission of prejudice. Fourth- and fifth-grade children completed measures of implicit and explicit pro-White/anti-Black prejudice, as well as a survey assessing child-parent identification. Parents completed a survey that measured their attitudes toward Blacks. As hypothesized, we found greater correspondence between parents’ prejudice and children’s prejudice among children who were highly identified with their parents than less identified children.     

Back and forth and in between: returning albanian migrants from Greece and Italy

On the basis of findings from a sample of Albanian migrants who have returned to their country of origin from Greece and Italy, we highlight that Greece attracts less skilled and less well off categories of migrants compared to Italy. However, the integration patterns tell a different story. In spite of the fact that Greece does not represent the first choice of Albanians seeking to migrate, and although those who go to Greece are not among the most qualified, nevertheless, they tend to adjust better to their host society and labour market. Furthermore, returning migrants from Greece seem to be better equipped and more likely to utilize the skills and knowledge acquired through migration compared to those returning from Italy.     

The search for HMAS Sydney II: Analysis and integration of survivor reports

We describe a novel application of cognitive psychology to the search for HMAS Sydney II and HSK Kormoran. Both ships sank off the west coast of Australia following an engagement during World War II. Tragically and mysteriously, there were no survivors from Sydney and, despite considerable interest in locating both ships, their positions remained unknown until their discovery in March 2008. The main evidence regarding the location of both ships consisted of reports by the German survivors from Kormoran. Working with the Finding Sydney Foundation, the group that ultimately found the ships, we developed a method to extract relevant information from these reports and to integrate it with other physical information and used this method to correctly identify the location of Kormoran to within 5 km. We describe this method and discuss the unique role played by cognitive psychology in solving a previously intractable problem. Copyright © 2010 John Wiley & Sons, Ltd.     

Migrant Entrepreneurship in Greece: Diversity of Pathways for Emerging Ethnic Business Communities in Thessaloniki

This paper examines aspects of immigrants’ entrepreneurship in Greece, focusing on the emergence of distinct ethnic business communities by migrants from China, Nigeria, Albania and the former USSR. Beginning from a literature review, it overviews the policy context and official statistics in Greece and discusses recent fieldwork findings in Thessaloniki. The diversity of entrepreneurial strategies and practises is explained through a typology based on the prevailing characteristics of immigrant businesses. We suggest that the entrepreneurship of migrants is embedded within the dynamics of immigrants’ integration and the broader factors on which this depends. This has important implications, calling for a realistic, coherent, inclusive and long-spanning migratory policy.     

Empathic deficits and alexithymia in trauma-related impulsive aggression

Our long term interest is to develop a developmental model of impulsive aggression based on a confluence of social, psychological and biological features. This approach incorporates neurobiological research, which has identified language processing deficits as a unique characteristic of impulsive aggressors and extends it to include emotional deficits. As an initial test of this hypothesis, we examined whether empathy and alexithymia were associated with impulsive aggression. Regressions were performed to explore the associations among impaired empathy, alexithymia, impulsive aggression, verbal and physical general aggression. Among impulsive aggressive veterans (n = 38) recruited from a VA trauma clinic, alexithymia predicted impulsive aggression and empathic deficits predicted verbal aggression. Neither emotional awareness deficit predicted general physical aggression in this middle-aged sample. Results suggested that empathic deficits were associated with general verbal aggression, but alexithymia was uniquely associated with impulsive aggression. Consideration of alexithymia in impulsive aggression has implications for its etiology, prevention and treatment. Published in 2008 by John Wiley & Sons, Ltd.
