Does binge eating play a role in the self-regulation of moods?

Self-reported emotional experiences and eating behaviors were studied in college students in an attempt to determine what types of emotional experiences precede and follow binge eating and how specific types of compensatory behaviors modify these experiences. First-year male and female students (N=390) were surveyed for depression, anxiety, health status, life satisfaction, and eating attitudes (EAT-26). Those reporting recurrent binge eating episodes were asked to describe their emotional feelings before and after bingeing and before and after compensatory activities. EAT-26 scores corresponding to scores previously reported for eating disordered patients were found in 9.7% of students. Binge eating was nearly twice as frequent among females (16.4%) as males (8.6%) Among females, positive relationships were found between specific EAT-26 factors scores and both anxiety and depression scores. The emotional antecedents and consequences of binge eating and of compensatory activities were compared in three sub-groups of individuals who reported recurrent bingeing with loss of self-control during binges. The three sub-groups consisted of individuals who reported, 1) bingeing without engaging in compensatory activities, 2) bingeing and compensating by means other than vomiting (fasting, exercising, or use of laxatives or diuretics), and 3) bingeing and compensating by vomiting. Regardless of the type of activity, those individuals who engaged in compensatory activities reported greater negative affect preceding binge episodes than those who did not compensate. In addition, contrary to expectations, negative affect did not decrease, but instead increased significantly, following binge episodes and decreased immediately before and after compensatory activities.     

Exploring Culture-Specific Differences in Beliefs about Causes, Kinship and the Heritability of Major Depressive Disorder: The Views of Anglo-Celtic and Chinese-Australians

The aim of this study was to explore cultural differences in causal attributions and beliefs about heritability of major depressive disorder (MDD). Face-to-face interviews with Anglo-Celtic- and Chinese-Australians community members with a family history of MDD were conducted and subjected to a rigorous qualitative analysis, using the computer software NVivo. Sixteen Anglo-Celtic-Australians and 16 Chinese-Australians were interviewed. Both groups believed that a combination of genetic and environmental factors contributed to MDD, that stress was an important cause of MDD, and that coping factors were significant moderators of the impact of stress on MDD. Both cultural groups believed that the causes of MDD affecting multiple family members included a shared family environment and a “contagion effect”, in addition to genetics. Unique to the Chinese-Australian group was the beliefs that parental pressures to exceed academically contributed to MDD; this cultural group also reported beliefs that depression was due to God’s will or alternatively fate, which in turn was related to attributions to feng shui and auspicious dates. This study documented key culture-specific differences in beliefs about causes and inheritance of MDD; such differences have major implications for clinician-patient communication about genetic risk associated with having a family history of MDD.     

A threshold theory account of psychometric functions with response confidence under the balance condition

The study of thresholds for discriminability has been of long‐standing interest in psychophysics. While threshold theories embrace the concept of discrete‐state thresholds, signal detection theory discounts such a concept. In this paper we concern ourselves with the concept of thresholds from the discrete‐state modelling viewpoint. In doing so, we find it necessary to clarify some fundamental issues germane to the psychometric function (PF), which is customarily constructed using psychophysical methods with a binary‐response format. We challenge this response format and argue that response confidence also plays an important role in the construction of PFs, and thus should have some impact on threshold estimation. We motivate the discussion by adopting a three‐state threshold theory for response confidence proposed by Krantz (1969, Psychol. Rev., 76, 308–324), which is a modification of Luce's (1963, Psychol. Rev., 70, 61–79) low‐threshold theory. In particular, we discuss the case in which the practice of averaging over order (or position) is enforced in data collection. Finally, we illustrate the fit of the Luce–Krantz model to data from a line‐discrimination task with response confidence.     

One therapist, four cultures: working with families in Greater China

Rather than addressing ethnicity through a pre–set cultural lens, I discuss how my experiences as a family therapy trainer in Singapore, Hong Kong, Taiwan and Shanghai taught me to understand culture through the lens of the family. Similarities and differences among these cultural domains were reviewed. I also demonstrate how each encounter shaped my emotional responses and ways of intervention in the course of family interviews. Even though I belong to the same ethnic background, I had to interact differently in different arenas, despite my cultural values and theoretical orientation.     

Parents’ perceptions of children’s executive functions across different cities

Culture is thought to strongly influence the development of executive functions (EF), such that ethnic groups with similar cultural origins are generally assumed to exhibit comparable levels of EF performance. However, other characteristics, such as urbanization and Westernization, may also affect EF performance in societies comprising different ethnic groups, even if the ethnic groups share a similar cultural origin. The present study aimed to compare the perceptions of parents in three cities [China–Shenzhen (ZH group), China–Hong Kong (HK group), and Singapore (SG group)] regarding the EF performances of their children, all of whom share the same genetic and cultural (i.e., Chinese) origin. The study recruited 95 children aged 5–6 years (ZH group = 32; HK group = 32; SG group = 31). Their parents were invited to complete the Behavior Rating Inventory of Executive Function (BRIEF). The ZH group had significantly lower BRIEF scores compared to both the HK and SG groups. However, the BRIEF scores of the HK and SG groups only differed significantly in terms of the Organization of Materials domain. The results suggest city-related differences in parents’ perceptions of their children’s EF performances, despite their similar genetic and cultural backgrounds. We additionally discuss further interpretations of our results and the limitations of this study.     

Branded entertainment: Gender differences in reactions to star ratings

The consumer behavior literature shows that men are externally focused and women are internally focused consumers. The authors conduct three studies to test gender differences in the use of media‐posted public ratings for deciding whether to recommend branded entertainment films. The Study 1 results indicate that men are more (less) likely to recommend films that have high (low) star ratings, but women are equally likely to recommend films regardless of star ratings. In an interesting twist, Study 2 results show that if women are momentarily distracted by being made more aware of their surroundings, they process information similarly to men and are more persuaded by public ratings. In Study 3, the authors replicate and extend the findings by including a no‐star control group and examining additional variables—film and brand attitudes and recommendations—with a no star rating control group. The overall results show that men (women) are more (less) likely to look to public ratings for forming film and brand attitudes and recommendations.     

Improving Motor Performance During Initial Skills Acquisition Through Regulatory Fit: An Experimental Study Based on Ball Throwing Task and Small Financial Reward

Regulatory focus theory (RFT) suggests that performance will be enhanced when there is a match between individual characteristics and environmental cues. Given that the application of RFT in the context of motor performance has been rarely examined, a ball-throwing task with small financial reward was conducted to test the theory. A total of 51 undergraduate students participated in this study. They were randomly assigned to either the promotion- or prevention-oriented task (which were different in terms of how the reward was instructed to be given). Results indicated that students performed better on ball throwing when the given instruction fit their relatively dominant regulatory focus. This finding supports the expectations of RFT. Implications and limitations were discussed.     

Control Beliefs and Faith as Stress Moderators for Korean American Versus Caucasian American Protestants

Examined relationships among negative life events, four locus of control attributions (Internality, Powerful Others, Chance, and God Control), and psychological distress for Korean American versus Caucasian American Protestants. Negative events and Powerful Others beliefs were positively related to distress, whereas Internality was negatively related to distress. Ethnicity and God Control interacted: The relationship between God Control beliefs and anxiety was negative for Caucasians but positive for Koreans. Three-way interactions (Ethnicity × Locus of Control × Negative Events) also emerged. As Caucasians' Powerful Others beliefs increased, the positive relationship between negative events and depression became stronger; Koreans' Powerful Others beliefs had no such effect. As Caucasians' God Control beliefs increased, the negative event–depression relationship changed from positive to negative; the reverse was true for Koreans. Findings support the value of assessing ethnoculture and religiousness in stressful life events research.     

An Infertility Primer for Family Therapists: II. Working with Couples Who Struggle with Infertility

The distress of infertility and its medical treatments are profound, and the effects reverberate in each partner, the couple dyad, and the couple's relationships with family, friends, and medical systems. Yet family therapists, like others in our society, are often uninformed or misinformed about the experience of infertility. While the legacies of infertility may be painful and enduring, they often remain unspoken, and hence may be overlooked in standard interviews. This article describes the experiences of couples struggling with infertility, most of whom have sought medical intervention, and it provides treatment interventions for guiding couples through this difficult and often uncharted terrain. Case vignettes derived from 2 years of this clinical research study are included.     

The stability and control of conditioned noise aversion in the tilt cage

Twenty-six rats were used to study the development of stable conditioned responding to terminate white noise (100 or 105 db) in a tilt cage apparatus. Preliminary work, with one end of the cage consistently associated with silence, demonstrated stability at a high level of cumulative noise-off time per session. Time spent at the noise-off cage end was unaffected by lay-off and showed adaptation to reversal of the cage end functions. Variability in reversal acquisition, insensitivity to stimulus intensity changes and persistence in remaining at one end of the cage in the absence of noise-termination contingencies indicated the need for more precise behavioral control. A schedule programming several reversals of the no-noise end at variable intervals within each session was developed. Performance on the latter schedule was characterized by stability of high noise-off times and also proved more sensitive than the preliminary method to stimulus intensity changes (55, 70, 100 db) as measured by both cumulated noise-off time and cage crossing rates. The ease of training combined with sensitivity to stimulus change and the lack of highly specific motor response requirements make this technique promising for use with animals potentially debilitated by drugs or surgical after-effects.
