A receiver operator characteristics analysis of treatment outcome in binge eating disorder to identify patterns of rapid response

The purpose of this study was to perform a receiver operator characteristics (ROC) analysis on a treatment sample from a randomized controlled treatment trial of participants with binge eating disorder (BED). An ROC analysis was completed with 179 adults in a 20-week treatment trial for BED to predict abstinence from binge eating at end of treatment. Percent reductions in binge eating episodes were examined following weeks 1 through 10 of treatment. The rate of percent decrease in binge eating episodes during treatment for BED was a significant predictor of clinical outcome at end of treatment. Participants who demonstrated a 15% reduction in binge eating episodes at week one were more likely to respond positively to treatment and achieve clinical remission. Findings from the current study suggest that a significant reduction in binge eating during the first week of treatment may be predictive of end of treatment remission in those with BED.     

Movement contributes to infants’ recognition of the human form

Three experiments demonstrate that biological movement facilitates young infants’ recognition of the whole human form. A body discrimination task was used in which 6-, 9-, and 12-month-old infants were habituated to typical human bodies and then shown scrambled human bodies at the test. Recovery of interest to the scrambled bodies was observed in 9- and 12-month-old infants in Experiment 1, but only when the body images were animated to move in a biologically possible way. In Experiment 2, nonbiological movement was incorporated into the typical and scrambled body images, but this did not facilitate body recognition in 9- and 12-month-olds. A preferential looking paradigm was used in Experiment 3 to determine if infants had a spontaneous preference for the scrambled versus typical body stimuli when these were both animated. The results showed that 12-month-olds preferred the scrambled body stimuli, 9-month-olds preferred the typical body stimuli and the 6-month-olds showed no preference for either type of body stimuli. These findings suggest that human body recognition involves integrating form and movement, possibly in the superior temporal sulcus, from as early as 9 months of life.     

Adjusting to death: the effects of mortality salience and self-esteem on psychological well-being, growth motivation, and maladaptive behavior

This research builds on terror management theory to examine the relationships among self-esteem, death cognition, and psychological adjustment. Self-esteem was measured (Studies 1-2, 4-8) or manipulated (Study 3), and thoughts of death were manipulated (Studies 1-3, 5-8) or measured (Study 4). Subsequently, satisfaction with life (Study 1), subjective vitality (Study 2), meaning in life (Studies 3-5), positive and negative affect (Studies 1, 4, 5), exploration (Study 6), state anxiety (Study 7), and social avoidance (Study 8) were assessed. Death-related cognition (a) decreased satisfaction with life, subjective vitality, meaning in life, and exploration; (b) increased negative affect and state anxiety; and (c) exacerbated social avoidance for individuals with low self-esteem but not for those with high self-esteem. These effects occurred only when death thoughts were outside of focal attention. Parallel effects were found in American (Studies 1-4, 6-8) and Chinese (Study 5) samples.     

TWO MEASURES OF PREFERENCE DURING FORCED-CHOICE ASSESSMENTS

A forced-choice preference assessment was conducted in which two dependent measures were used to select preferred stimuli: (a) approach responding and (b) latency to the first aberrant response. Stimuli identified as preferred based on both dependent measures were then evaluated during treatment. The results suggested that latency may be a useful measure in the selection of preferred stimuli during forced-choice assessments.     

Intergroup Ratio and the Contact Hypothesis1

This study assessed whether contact between members of 2 social groups generalized to contact in another setting, as well as influenced their intercultural knowledge and acceptance. Subjects were 244 international (mainly ethnic Chinese) and Anglo-Australian students living in 3 student residence halls, with each group comprising a numerical majority, equal proportion, and a numerical minority in one of the residential halls. As anticipated, group ratio exerted a systematic effect on the amount of intercultural contact, with most contact by members of a numerical minority, regardless of student group. Importantly, the pattern of residence-hall contact tended to generalize to the wider university environment and to influence intercultural knowledge and acceptance. However, contact was not unqualified in its effects, particularly in relation to members of the cultural majority.     

A Case-Series of Reflective Family Play: Therapeutic Process,Feasibility, and Referral Characteristics

Evidence-based interventions for infants and preschoolers, and their families, have largely focused on the mother-child dyad. In response to the increasing need to diversify treatment approaches in the under six population and include the whole family system, we have developed a new treatment approach called Reflective Family Play (RFP). A manualized, whole-family therapy, RFP allows for the involvement of two parents and siblings when working with infants or young children. In this case-series, we used a qualitative chart review to examine the therapeutic process, acceptability, and feasibility of RFP for 22 families with children ages 0–6, who participated in RFP. We also sought to better understand the referral characteristics of those families who participated in RFP by comparing them to families who were referred to and participated in an established dyadic approach during the same time-period. Session-by-session coding of clinician chart notes revealed evidence of positive shifts throughout the RFP process, including more whole-family play, improvements in coparenting, and better parental mentalization. Parents reported improvements in presenting concerns in all but one case. Improvements in coparenting, sibling relationships, and family alliance were also reported by parents after RFP. Clinical implications and directions for future research are discussed.     

Working memory capacity predicts search accuracy for novel as well as repeated targets

Visual search behaviour is guided by mental representations of targets that direct attention toward relevant features in the environment. Electrophysiological data suggests these target templates are maintained by visual working memory during search for novel targets and rapidly transfer to long term memory with target repetition. If this account is correct, an individual’s working memory capacity should be more predictive of search performance for novel targets than repeated targets. Across six experiments, we tested this hypothesis using both single (Experiments 5 and 6) and multiple (Experiments 1–4) target search tasks with three different types of stimuli (real world objects, letters, and triple conjunction shapes). Each target set was repeated for six consecutive trials. In addition, we estimated visual working memory capacity using a change detection working memory task. Overall, working memory capacity did not predict response time or efficiency in the visual search task. However, working memory capacity was equally predictive of search accuracy for both novel and repeated targets. These results suggest that working memory requirements do not substantially differ between novel and repeated target search, and working memory capacity may continue to play an important role in the encoding or maintenance of target representations after they are presumed to be in long term memory.     

The effects of a wisdom intervention in a Christian congregation*

Psychological research on the topic of wisdom is limited in its incorporation of religion and spirituality. This gap in psychological literature may serve to limit a thorough understanding of wisdom. Positive psychology may allow for some rapprochement in wisdom and spirituality. In collaboration with leaders of a local Friends (Quaker) congregation, two studies investigated the effects of a spiritually informed wisdom intervention delivered in the context of a faith community. Participants for Study 1 consisted of 27 young adults (24 completed both the pre and post questionnaire) and a comparison group consisting of 32 young adults. The intervention was designed to increase participants’ abilities in cognitive, affective and moral domains. Significant group by time interaction effects were found among measurements of practical wisdom, post-formal thinking and subjective well-being, with those in the experimental group showing changes in the expected direction. Study 2 involved qualitative analyses of interviews with 15 of the wisdom participants regarding their changing views of wisdom. Themes emerging from the interviews included a multiple-perspectives view of wisdom, the relational nature of learning wisdom, the importance of taking a reflective perspective, and congruence between what one knows and how one lives. Implications for studying wisdom alongside religion and spirituality are considered.
