Trauma memories on trial: is cross-examination a safeguard against distorted analogue traumatic memories?

Trauma memories can feel more disorganised than more mundane memories. That may be problematic in legal contexts. Here we examined: (a) whether that disorganised feeling makes people more susceptible to suggestive questioning during direct examination; and (b) whether cross-examination is the safeguard it is purported to be: that is, we examined whether cross-examination can uncover and correct distorted trauma memories. We showed participants a film depicting a graphic car accident. For some participants, the film unfolded in a temporally disorganised way. We then interviewed participants immediately after the film regarding what they had seen: this ‘direct examination’ included free recall, cued recall and yes/no questions, some of which were misleading. Then, 48 hours later, a second interviewer cross-examined participants. Contrary to our predictions, neither manipulation of the film's temporal organisation, nor participants’ self-reported feelings of event disorganisation significantly affected their accuracy of the film during direct or cross-examination nor their recognition memory of the film. Instead, we found that regardless of whether participants’ memories were distorted by the direct examination, the suggestive nature of the cross-examination introduced sufficient doubt that participants were willing to change their answers. We conclude that traumatic memories are vulnerable to suggestive questioning and, unfortunately, cross-examination is not the legal system's fail-safe corrective influence.     

Healthcare at Your Fingertips: The Professional Ethics of Smartphone Health-Monitoring Applications

Health professionals are inundated by the surfeit of health apps while lacking guidance to help them critically evaluate whether a particular health-monitoring app is safe, likely to lead to clinical benefit, and not introduce additional liability. Our objective is not to argue for or against the use of mobile health-monitoring apps but to illuminate the associated ethical issues and provide recommendations to guide the ethical decision-making process for clinicians who are considering the use of a mobile health-monitoring app. To this end, the Canadian Code of Ethics for Psychologists is used as a framework to situate recommendations.     

Pediatric Whole Exome Sequencing: an Assessment of Parents’ Perceived and Actual Understanding.

Whole exome sequencing (WES) is an integral tool in the diagnosis of genetic conditions in pediatric patients, but concerns have been expressed about the complexity of the information and the possibility for secondary findings that need to be conveyed to those deciding about WES. Currently, there is no validated tool to assess parental understanding of WES. We developed and implemented a survey to assess perceived and actual understanding of WES in parents who consented to clinical WES for their child between July 2013 and May 2015. Fifty-three eligible surveys were returned (57% response rate). Areas with both low perceived and actual understanding about WES included how genes are analyzed and lack of protection against life insurance discrimination. Parents also had low actual understanding for two questions related to secondary findings – reporting of secondary findings in a parent (if tested) and whether secondary findings can be related to traits such as height and hair color. Further work to develop a validated tool to assess understanding of WES would be beneficial as WES is integrated more frequently into clinical care.     

Systematic review of the psychometric properties of transphobia scales

Introduction: Prejudice and discrimination against transgender individuals (i.e., transphobia) is pervasive and has been shown to have pernicious effects on the physical (e.g., substance abuse and other self-harm behaviors) and psychological (e.g., depression and suicidal ideation) well-being of those targeted.

Aims: To date, a review of the psychometric properties of scales assessing transphobia has not been conducted; this gap compromises researchers' ability to make informed measurement decisions.

Methods: In the current study, 61 articles that contained 83 scales were identified, and their adherence to best practices in psychometric testing was evaluated.

Results: Most of the transphobia scales included in the current review did not provide sufficient information about item generation and refinement, scale dimensionality, scale score reliability, or validity. Each scale was entered into a table and was ranked on the basis of its total score. A score of 1 was issued for each psychometric feature that adhered to best practice guidelines, with total scores ranging from 0 to 5 (i.e., higher scores denote greater psychometric soundness).

Discussion: Properties of the reviewed scales are summarized and recommendations are made for future transphobia scale development and validation. The measures that emerged as possessing the highest scores and, subsequently, the greatest utility are identified.     

On the relative contributions of noncontingent reinforcement and escape extinction in the treatment of food refusal

In the current investigation, we evaluated the relative effects of noncontingent reinforcement (NCR), escape extinction, and a combination of NCR and escape extinction as treatment for the feeding problems exhibited by 4 children. For each participant, consumption increased only when escape extinction was implemented, independent of whether NCR was present or absent. These results were consistent with prior research suggesting that positive reinforcement alone is insufficient for increasing consumption, and that escape extinction often is necessary to increase and maintain food acceptance. However, NCR appeared to decrease inappropriate behavior for some participants.     

Intention to learn influences the word frequency effect in recall but not in recognition memory

Watkins, LeCompte, and Kim (2000) suggested that the recall advantage for rare words in mixed lists is due to a compensatory study strategy that favors the rare words. They found the advantage was reversed when rare and common words were studied under incidental learning conditions. The present study investigated the possibility that the rare-word advantage in recognition memory is also the result of a compensatory study strategy. Experiment 1 replicated the findings of Watkins et al. that the rare-word advantage in recall is eliminated under incidental learning conditions. In contrast, Experiment 2 showed that the rare-word advantage in recognition memory is maintained under both intentional and incidental learning conditions. Experiment 3 replicated the results of Experiments 1 and 2 using different stimuli and a different orienting task. Finally, Experiment 4 showed that the rare-word advantage in recognition is maintained with pure lists. These findings show that the rare-word advantage in recognition memory is not the result of a compensatory study strategy. Instead, rare words are encoded more distinctively than common words, irrespective of participants' intention to remember them.     

A window on the normal development of sensitivity to global form in Glass patterns

We studied the development of sensitivity to global form in 6-year-olds, 9-year-olds, and adults (n = 24 in each group) using Glass patterns with varying ratios of paired signal dots to noise dots. The developmental pattern was similar whether the global structure within the Glass patterns was concentric or parallel. Thresholds were equally immature for both types of pattern at 6 years of age (about twice the adult value) but were adult-like at 9 years of age. Together, the results indicate that the cortical structures involved in the processing of global form achieve functional maturity between 6 and 9 years of age. During middle childhood, the mechanisms mediating sensitivity to concentric structure develop at the same rate as those mediating sensitivity to parallel structure.     

Assessing normative approaches to communicating violence risk: a national survey of psychologists

There is growing attention to the importance of violence risk communication, and emerging empirical evidence of how evaluating clinicians who conduct risk assessments communicate their conclusions about the risk of violence toward others. The present study addressed the perceived value of different forms of risk communication through a national survey of practicing psychologists (N = 1,000). Responses were received from a total of 256 participants, who responded to eight vignettes in which three factors relevant to risk communication were systematically varied in a 2 x 2 x 2 within-subjects design, counterbalanced for order: (i) risk model (prediction oriented versus management oriented), (ii) risk level (high risk versus low risk), and (iii) risk factors (static versus dynamic). Participants were asked to rate the value of six styles of risk communication for each of eight vignettes. The most highly valued style of risk communication involved identifying risk factors applicable to the individual, and specifying interventions to reduce risk. These results were consistent with findings from several previous studies in this area, and reflect an emerging trend in preferences for style and context of risk communication of violence.     

Short- and Long-Term Impact of Receiving Genetic Mutation Results in Women at Increased Risk for Hereditary Breast Cancer

Forty-seven unaffected women from high-risk breast cancer families who had received results for hereditary breast/ovarian predisposition genes between 1 month and 5 years ago were interviewed regarding their experiences. Women responded to open-ended questions. The initial emotional turmoil reported by most was generally short lived. However, the impact of genetic testing went beyond the individual to the extended family and social context, particularly in the short-term. A common theme was the difficulty associated with divulging a result to family members, who were also adjusting to their own result. The majority of carriers reported advantages that were both physical (options for surveillance programs and prophylactic surgery) and emotional (reduced uncertainty, increased awareness of options and knowledge about risk, preparation time). Most carriers reported no change in lifestyle although some reported discovering their mutation status as a positive life-changing experience. Implications for genetic counseling and further research are discussed.     

Parent–Child Interaction Therapy and Chronic Illness: A Case Study

We examined the outcome of parent–child interaction therapy (PCIT) for a child diagnosed with Oppositional Defiant Disorder (ODD) and cancer. Robert, a 4-year-old Caucasian male, showed significant and meaningful changes in his behavior over the course of 13 weeks of PCIT, and Robert no longer met diagnostic criteria for ODD following treatment. His scores on the Eyberg Child Behavior Inventory and the Achenbach Child Behavior Checklist were in the clinical range before treatment and in the normal range at the conclusion of treatment. His mother also reported dramatic improvements in Robert's behavior during medical visits. Physician and social worker reports were consistent with her report. Such anecdotal data may have implications for the generalization of compliance to the medical setting for children with chronic illnesses. The results of this case study should prompt further investigation of parent-training interventions for children with chronic illnesses and disruptive behavior.
