Visual working memory is disrupted by covert verbal retrieval

If working memory (WM) depends on a central resource—as is posited in some theories, but not in others—it should be possible to observe interference between tasks that share few features with each other. We investigated whether interference with WM for visual arrays would occur, even if the interfering task required neither visual processing nor overt responding. In an auditory-verbal interfering task, a response was to be made if a word was recognized as having come from one of two prelearned lists, but not from the other list. As compared with nonretrieval control conditions, even covert verbal memory retrieval disrupted the storage of visual items held in WM. A second experiment ruled out verbal recoding of the visual arrays as the basis of interference. The results indicate that visual WM and verbal long-term retrieval share a central resource (e.g., attention).     

Seven-year-olds allocate attention like adults unless working memory is overloaded

Previous studies have indicated that visual working memory performance increases with age in childhood, but it is not clear why. One main hypothesis has been that younger children are less efficient in their attention; specifically, they are less able to exclude irrelevant items from working memory to make room for relevant items. We examined this hypothesis by measuring visual working memory capacity under a continuum of five attention conditions. A recognition advantage was found for items to be attended as opposed to ignored. The size of this attention-related effect was adult-like in young children with small arrays, suggesting that their attention processes are efficient even though their working memory capacity is smaller than that of older children and adults. With a larger working memory load, this efficiency in young children was compromised. The efficiency of attention cannot be the sole explanation for the capacity difference.     

A Pilot Study of the Effects of Cognitive-Behavioral Conjoint Therapy for Posttraumatic Stress Disorder on Parenting

Parental posttraumatic stress disorder (PTSD) is associated with parenting difficulties. Cognitive-behavioral conjoint therapy for PTSD (CBCT for PTSD) improves PTSD symptoms, relationship adjustment, and partners’ mental health functioning. However, the impact of CBCT for PTSD on parenting competency is unknown. In this pilot study, the effects of CBCT for PTSD on parenting competency were investigated in 14 individuals (6 patients with PTSD and 8 partners) who had children under age 18. Results suggested that most participants perceived themselves as competent in their parenting prior to treatment, and some enhancements in competency occurred following CBCT for PTSD. Moreover, changes in parenting competency were associated with improvements in patient-rated PTSD. Adjunctive interventions targeting parenting and goals for future research are discussed.     

A Case Study of Cognitive-Behavioral Conjoint Therapy for Combat-Related PTSD in a Same-Sex Military Couple

Military deployments to Iraq and Afghanistan are associated with increased risk for posttraumatic stress disorder (PTSD), depression, and relationship impairment. Unfortunately, the perceived stigma associated with seeking deployment-related behavioral health care in military settings has been a significant barrier to care. Historically, active-duty military service members involved in same-sex intimate relationships have experienced further stressors and barriers to care related to additional stigma and lack of social support. Prior federal regulations excluded sexual minorities from openly serving in the military, thereby limiting the available behavioral health services for same-sex couples. Since this ban was lifted after the repeal of the U.S. policy known as "Don’t Ask, Don’t Tell" in 2010, gay and lesbian service members have increased opportunities to obtain behavioral health care. One therapy that is newly available to sexual minority military couples is Cognitive-Behavioral Conjoint Therapy (CBCT), which effectively addresses co-occurring PTSD and relationship dysfunction. This case study illustrates the use of CBCT for the treatment of deployment-related PTSD in a same-sex active-duty military couple. After completing all 15 CBCT sessions, the couple reported clinically meaningful changes in the service member’s PTSD symptoms, which was maintained at the 2-month follow-up. The results of this case study indicate that CBCT for PTSD can have positive treatment outcomes with military same-sex couples. Further clinical implications are discussed.     

Determining who to question, what to ask, and how much information to ask for: the development of inquiry in young children

To obtain reliable information, it is important to identify and effectively question knowledgeable informants. Two experiments examined how age and the ease of distinguishing between reliable and unreliable sources influence children’s ability to effectively question those sources to solve problems. A sample of 3- to 5-year-olds was introduced to a knowledgeable informant contrasted with an informant who always gave inaccurate answers or one who always indicated ignorance. Children were generally better at determining which informant to question when a knowledgeable informant was contrasted with an ignorant informant than when a knowledgeable informant was contrasted with an inaccurate informant. In some cases, age also influenced the ability to determine who to question and what to ask. Importantly, in both experiments, the strongest predictor of accuracy was whether children had acquired sufficient information; successful problem solving required integrating knowledge of who to question, what to ask, and how much information to ask for.     

A comparison of methods for teaching receptive labeling to children with autism spectrum disorders

Many early intervention curricular manuals recommend teaching auditory-visual conditional discriminations (i.e., receptive labeling) using the simple-conditional method in which component simple discriminations are taught in isolation and in the presence of a distracter stimulus before the learner is required to respond conditionally. Some have argued that this procedure might be susceptible to faulty stimulus control such as stimulus overselectivity (Green, 2001). Consequently, there has been a call for the use of alternative teaching procedures such as the conditional-only method, which involves conditional discrimination training from the onset of intervention. The purpose of the present study was to compare the simple-conditional and conditional-only methods for teaching receptive labeling to 3 young children diagnosed with autism spectrum disorders. The data indicated that the conditional-only method was a more reliable and efficient teaching procedure. In addition, several error patterns emerged during training using the simple-conditional method. The implications of the results with respect to current teaching practices in early intervention programs are discussed.     

The Effects of Instructions on Mothers’ Ratings of Child Attention-Deficit/Hyperactivity Disorder Symptoms

We examined whether instructional materials describing how to rate child ADHD symptoms would improve the accuracy of mothers’ ratings of ADHD symptoms presented in standard child behavior stimuli, and whether instructions would be equally effective across a range of maternal depressive symptoms and family incomes. A community sample of 100 mothers with 5 to 12 year old sons were randomly assigned to either receive or not receive the instructions. All mothers watched standard video recordings of boys displaying nonproblem behavior, ADHD symptoms, ADHD plus oppositional behaviors, or ADHD plus anxious behaviors, and then rated the ADHD symptoms of the boys in the videos. These ratings were compared to ratings of the boys’ ADHD symptoms made by objective coders. Results indicated an interaction such that the instructional materials improved the agreement between mothers’ and coders’ ratings, but only for mothers at lower family income levels. The instructional materials improved all mothers’ open-ended responses regarding knowledge of ADHD. All mothers rated more ADHD symptoms in boys with comorbid oppositional or anxious behaviors, and this effect was not reduced by the instructional materials. The potential utility of these instructions to improve the accuracy of ratings of child ADHD symptoms is explored.     

Exposure to maternal vs. paternal partner violence,PTSD, and aggression in adolescent girls and boys

Adolescents who witness interparental violence (IPV) are at increased risk for perpetrating aggressive acts. They are also at risk for post‐traumatic stress disorder (PTSD). In this study, we examined the relation between exposure to maternal vs. paternal physical IPV and adolescent girls' and boys' aggressive behavior toward mothers, fathers, friends, and romantic partners. We also assessed the influence of PTSD (as assessed by the Diagnostic Interview for Children and Adolescents‐IV (DICA‐IV)) on the relation between exposure to IPV and aggressive behavior. Participants were 63 girls and 49 boys, ages 13–18, consecutively admitted to a youth correctional facility or assessment facility designated to serve aggressive and delinquent youth. Structural equation modeling was used to estimate unique relations between exposure to maternal vs. paternal IPV and youth aggression in relationships. Girls who observed their mothers' aggressive behavior toward partners were significantly more aggressive toward friends. Similarly, boys who witnessed their fathers' aggression were significantly more aggressive toward friends. Adolescent girls and boys who observed aggression by mothers toward partners reported significantly higher levels of aggression toward their romantic partners. Approximately one third of our sample met PTSD criteria; the relation between exposure to parental IPV and aggression was stronger for individuals who met criteria for PTSD. The implications of understanding the relations between parents' and their daughters' and sons' use of aggression are discussed within the context of providing support for families in breaking intergenerational patterns of violence and aggression.
