Changes in Female Rape Myth Acceptance Among College Students: A 20-Year Perspective

In this study, we compared changes in female rape myth acceptance (RMA) between 1998 and 2018 in two separate samples of college students from the same university in the U.S. Pacific Northwest. The primary measure was the Attitudes Toward Rape Victims Scale (ARVS). First, we examined the factor structure of the ARVS with confirmatory factor analysis, finding good fit for a four-factor model comprising Assigning Blame or Responsibility to the Victim (Blame/Responsibility), Considering the Victim as Deserving of Sexual Violence (Deserving), Undermining the Victim’s Credibility (Undermine Credibility), and Trivializing the Experience or Denigrating the Victim (Trivialization/Denigration). Second, we used profile analysis, a type of multivariate repeated-measures ANOVA, to examine the main and interactive effects of Survey Year, Gender, and ARVS Subscale and Item within each subscale. At the subscale level, we found large main effects for Survey Year, Gender, and Subscale, with lower scores for the 2018 sample, women, and Deserving and Trivialization/Denigration, relative to Undermine Credibility and Blame/Responsibility. We also found interactions between Survey Year and Subscale and Gender and Subscale, indicating non-parallel profiles for the 1998 versus 2018 samples and women versus men. We found similar patterns at the item level within each subscale. These results indicate a substantial decline of female RMA in college students over a 20-year period, replicate the well-established gender difference in female RMA, and demonstrate that RMA varies by item content.

Understanding culture across species

Recent claims of culture in great apes have provoked fervent argument about the 'true' definition of culture, most of which has been unhelpful. Instead, a range of definitions should be used to explore different aspects of the cognitive processes that together result in human culture, many of which can be productively studied in non-humans. A richer cognitive account of the contents of culture needs to be developed and used to compare animal and human cultures, instead of sterile searching for a cognitive Rubicon between them. Exploring six views of culture, this article highlights the fundamental contrast of whether culture evolves as a by-product of cumulative change in cognitive mechanisms, or whether it is actively selected for its advantages.     

Increased wait-list time predicts dropout from outpatient enhanced cognitive behaviour therapy (CBT-E) for eating disorders

Between 30 and 70% of patients with eating disorders drop out from outpatient treatment. However, research has been unable to identify factors that consistently predict dropout from eating disorder treatment. Most studies have exclusively investigated the role that individual patient characteristics play in dropout and have ignored more process-based factors such as expectations about treatment, the therapeutic alliance, or time spent on a treatment waiting list. This study aimed to investigate the roles of both individual patient characteristics and process-based factors in dropout from outpatient treatment for eating disorders. The study involved data collected from consecutive eating disorder referrals to the only public specialist eating disorder service for youth and adults in Perth, Western Australia. The standard treatment provided at this service is Enhanced Cognitive Behaviour Therapy on an individual basis. The study involved 189 patients referred to the service between 2005 and 2010. Forty five percent of this sample dropped out of treatment. Results showed that, in this sample, two individual factors, lowest reported weight and the tendency to avoid affect, and one process-based factor, time spent on the wait list for treatment, were significant predictors of dropout. These findings are valuable because a process-based factor, such as wait-list time, may be easier to address and modify than a patient's weight history or the trait of mood intolerance. Increased resources for eating disorder services may reduce waiting list times which would help to reduce dropout and maximize treatment outcomes.     

Assessment of children's receptive vocabulary using event-related brain potentials: Development of a clinically valid test

The combined verbal and motor impairments characteristic of children with disorders such as Cerebral Palsy (CP) frequently compromise the accuracy of standard psychometric assessments. What is needed is a test to measure language that does not require verbal or motor responses. This study was designed to determine whether single-word receptive vocabulary could be assessed in young children without CP, using an ERP-compatible test based on Form M of the Peabody Picture Vocabulary Test-Revised (PPVT-R). Fifteen 10-year-old children with normal levels of psychometric intelligence participated. Ninety pictures were selected from the PPVT-R (Form M), representing three levels of single-word receptive vocabulary (Preschool, Child-Adolescent, Adult). Each picture was presented twice (pseudo-random), once paired with a spoken word that was semantically congruent with the picture and once paired with a semantically incongruent word. The children's N400 was significantly larger to incongruent than to congruent pairs, but only when the vocabulary was within their repertoire. The results are discussed in terms of electrophysiologic correlates of acquired language and the clinical use of this ERP test as an adjunct to assessing patients with moderate to severe communication and/or motor impairments (e.g., cerebral palsy, autism, head injury).     

Simultaneous Semipermeable Groups for Mothers and Their Early Latency-Age Boys

Abstract

Bonding is an ongoing aspect of intersubjective experience, a type of mental relationship to oneself and others. As a behavioral mode, bonding utilizes verbal and nonverbal communication primarily to establish a basic feeling of connection between individuals. Bonding is the floor, a cognitive-affective state that precedes and prepares the way for the complex processes underlying identification. The concept relates to Bion’s early theory of basic assumptions, and takes on new and different meanings according to his later ideas regarding social communication. Bonding is also a therapeutic posture or technique, an element in the establishment of group cohesion, the positive transference, and therapeutic and group alliance. Case examples illustrate how the therapist and other group members bring a complex of bonding needs and anxieties that must be negotiated to establish and maintain bonding, which is a necessary condition for successful therapeutic work.     

Behavioral effects of delayed timeouts from reinforcement

Timeouts are sometimes used in applied settings to reduce target responses, and in some circumstances delays are unavoidably imposed between the onset of a timeout and the offset of the response that produces it. The present study examined the effects of signaled and unsignaled timeouts in rats exposed to concurrent fixed‐ratio 1 fixed‐ratio 1 schedules of food delivery, where each response on one lever, the location of which changed across conditions, produced both food and a delayed 10‐s timeout. Delays of 0 to 38 s were examined. Delayed timeouts often, but not always, substantially reduced the number of responses emitted on the lever that produced timeouts relative to the number emitted on the lever that did not produce timeouts. In general, greater sensitivity was observed to delayed timeouts when they were signaled. These results demonstrate that delayed timeouts, like other delayed consequences, can affect behavior, albeit less strongly than immediate consequences.
