A comparison of two multicomponent procedures to increase food consumption

We compared two procedural variations of response cost (RC) of preferred materials to increase mouth clean in a five‐year‐old boy diagnosed with autism. Noncontingent presentation of preferred materials (NCR) was compared to differential reinforcement of alternative behavior (DRA) when returning preferred materials once they have been removed for refusal or expulsion of food. Results indicated that both procedures increased swallowing and reduced problem behavior; however, NCR + RC was superior to DRA + RC with respect to overall mean and initial treatment measures.

Cognitive Processing Therapy for Acute Stress Disorder Resulting From an Anti-Gay Assault

This case study describes Cognitive Processing Therapy (CPT) with a 30-year-old gay man with symptoms of acute stress disorder (ASD) following a recent homophobic assault. Treatment addressed assault-related posttraumatic stress disorder symptoms and depressive symptoms. Also addressed were low self-esteem, helplessness, and high degrees of internalized homophobia. Client symptomatology was tracked using the PTSD Symptom Scale and the Beck Depression Inventory over the course of 12 sessions and for a 3-month posttermination session. Symptoms were significantly reduced by the end of the 12-week therapy and were maintained at 3-month follow-up. This case highlights the utility of this therapy in targeting both ASD symptoms and internalized homophobia relating to experiencing a hate crime-related assault. The authors elaborate on theoretical and applied issues in adapting a structured cognitive-behavioral intervention to the treatment of ASD symptoms associated with experiencing a hate crime.     

Medical Students' Motivations to Volunteer: An Examination of the Nature of Gender Differences

A sample of medical students was surveyed using the Volunteer Functions Inventory, an instrument that assesses the importance of 6 possible motives to volunteer that range from altruistic and humanitarian concern for others to more self-interested, career-related motives. Researchers in the past have described mean differences and rank differences for gender. Profile analysis was conducted to assess the relative importance of each motive by gender. Women rated all motives higher than did men. The relative ranking of the importance of the motives was similar for both genders. Contrary to previous studies, women rated instrumental motives at least as high as did men. Both genders rated altruistic motives highly. The results of this study may be used to inform a training curriculum or advertising campaign aimed at increasing volunteer efforts.     

Effects of Lipopolysaccharide on Consolidation of Partial Learning in the Y-Maze

Research on consolidation of long-term memory suggests that acute immune system activation induced by endotoxin lipopolysaccharide (LPS) may disrupt consolidation of newly acquired learning. Adult male Sprague-Dawley rats were trained to perform a simple Y-maze task and were immediately afterwards administered LPS (15 microg/kg) or saline. After a seven-day interval, subjects were returned to the Y-maze and were retrained to criterion. It was found that subjects treated with saline required significantly fewer trials to relearn the task relative to the LPS group and a no-partial-learning control group, which themselves did not differ. These results are most readily explained in terms of a disruptive effect of acute immune system activation on consolidation of newly induced acquired memories.     

The development of metasuggestibility in children

One component of metasuggestibility is the understanding that a person's statements can influence another person's reports. The purpose of the present study was to examine the development of this understanding in school‐aged children. We produced a short video in which a boy makes a false allegation about being hit following an adult's suggestive interview. Children aged 6–13 years (N = 196) watched the video and answered open‐ended and forced‐choice questions about why the boy made a false allegation. The 6‐ and 7‐year‐olds performed poorly on all question types, whereas the 12‐ and 13‐year‐olds were at ceiling. There were developmental increases in metasuggestibility between 8 and 11 years. Our findings indicate that metasuggestibility undergoes prolonged development well into the school years. Implications for child witness training programs are discussed.

Minimising risks and distractions for young drivers and their passengers: An evaluation of a novel driver–passenger training program

The purpose of the present study was to evaluate a pilot program designed to teach communication skills to young drivers and passengers. Sixty-two young males recruited as 31 pairs of friends, all aged between 18 and 21 years and holding a probationary drivers licence, were randomly assigned to a training or no-training condition. A training program was developed based upon elements of existing team training programs. Driver and passenger pairs operated a driving simulator through scenarios designed to measure aspects of safe driving behaviour and hazard response. Communications between driver and passenger were also measured. All participants were administered the Driver Behaviour Questionnaire before and approximately 2 months after simulator testing. Compared to the untrained group the trained participants exhibited a larger following distance, reduced speed significantly when faced with an unexpected hazard on the road, and exhibited more safe communications. Although current passenger restrictions are warranted, the present results reveal an alternative view of adolescent passengers: rather than being a negative influence on drivers, adolescent passengers can potentially be trained to become a positive influence.     

Age-related changes in the signal value of tears

Emotional tears may be uniquely human and are an effective signal of distress in adults. The present study explored whether tears signal distress in younger criers and whether the effect of tears on observers is similar in magnitude across the life span. Participants rated photographs of crying infants, young children, and adults, with tears digitally removed or added. The effectiveness of tears in conveying sadness and eliciting sympathy was greatest for images of adults, intermediate for images of children, and least potent for images of infants. These findings suggest that the signal value of tears varies with the age of the crier. The results may shed light on the functional significance of crying at different stages of human development.     

The impact of civility interventions on employee social behavior, distress, and attitudes

Although incivility has been identified as an important issue in workplaces, little research has focused on reducing incivility and improving employee outcomes. Health care workers (N = 1,173, Time 1; N = 907, Time 2) working in 41 units completed a survey of social relationships, burnout, turnover intention, attitudes, and management trust before and after a 6-month intervention, CREW (Civility, Respect, and Engagement at Work). Most measures significantly improved for the 8 intervention units, and these improvements were significantly greater than changes in the 33 contrast units. Specifically, significant interactions indicating greater improvements in the intervention groups than in the contrast groups were found for coworker civility, supervisor incivility, respect, cynicism, job satisfaction, management trust, and absences. Improvements in civility mediated improvements in attitudes. The results suggest that this employee-based civility intervention can improve collegiality and enhance health care provider outcomes.     

LGB-Affirmative Cognitive Behavioral Treatment for Social Anxiety: A Case Study Applying Evidence-Based Practice Principles

Guided by the American Psychological Association's principles of evidence-based practice, this article reviews a single-case treatment outcome study whereby a client characteristic, sexual identity, was integrated into the assessment and treatment of social anxiety symptoms. The case involved a young adult European-American male who presented to a training clinic with a primary diagnosis of social anxiety disorder as well as secondary symptoms of excessive worry and concerns of sexual identity confusion. Recent evidence suggests that gay men report more symptoms of social anxiety when compared to heterosexual men, and those who make more efforts to conceal their sexual identity experience increased anxiety and have greater difficulty committing to a personal identity. Further, it has been hypothesized that fear of rejection from heterosexual individuals underlies this anxiety. The client attended 50 sessions over the course of 18 months. Treatment progress was assessed via self-report questionnaires assessing social anxiety and worry. Consistent with principles of evidence-based practice, a cognitive behavioral treatment protocol was employed at the outset of therapy and resulted in a decline in the client's social anxiety scores. However, once the case conceptualization and treatment focus shifted to focus on sexual identity, his scores continued to decline at an even steeper rate. He ultimately came to identify himself as having a same-sex sexual orientation, began living his life in a manner consistent with that identification, and reported a number of positive outcomes at termination of therapy. Implications for treatment of social anxiety in sexual minorities are discussed.     

Immediate and delayed effects of word frequency and word length on eye movements in reading: a reversed delayed effect of word length

Three experiments examined the effects in sentence reading of varying the frequency and length of an adjective on (a) fixations on the adjective and (b) fixations on the following noun. The gaze duration on the adjective was longer for low frequency than for high frequency adjectives and longer for long adjectives than for short adjectives. This contrasted with the spillover effects: Gaze durations on the noun were longer when adjectives were low frequency but were actually shorter when the adjectives were long. The latter effect, which seems anomalous, can be explained by three mechanisms: (a) Fixations on the noun are less optimal after short adjectives because of less optimal targeting; (b) shorter adjectives are more difficult to process because they have more neighbors; and (c) prior fixations before skips are less advantageous places to extract parafoveal information. The viability of these hypotheses as explanations of this reverse length effect on the noun was examined in simulations using an updated version of the E-Z Reader model (A. Pollatsek, K. Reichle, & E. D. Rayner, 2006c; E. D. Reichle, A. Pollatsek, D. L. Fisher, & K. Rayner, 1998).
