The neural bases of distracter-resistant working memory

A major difference between humans and other animals is our capacity to maintain information in working memory (WM) while performing secondary tasks, which enables sustained, complex cognition. A common assumption is that the lateral prefrontal cortex (PFC) is critical for WM performance in the presence of distracters, but direct evidence is scarce. We assessed the relationship between fMRI activity and WM performance within subjects, with performance matched across distracter and no-distracter conditions. Activity in the ventrolateral PFC during WM encoding and maintenance positively predicted performance in both conditions, whereas activity in the presupplementary motor area (pre-SMA) predicted performance only under distraction. Other parts of the dorsolateral and ventrolateral PFCs predicted performance only in the no-distracter condition. These findings challenge a lateral-PFC-centered view of distracter resistance, and suggest that the lateral PFC supports a type of WM representation that is efficient for dealing with task-irrelevant input but is, nonetheless, easily disrupted by dual-task demands.     

Cross-sectional and longitudinal predictors of well-being: invariance across 25 years

This study addressed: (a) whether any changes in well-being over time could be attributed to participants’ aging or to economic or historical events; (b) whether predictors (e.g. age, religiosity, and financial status) were similarly associated with well-being in cohorts of college seniors assessed at different times; and (c) whether predictors of well-being were similar for the same cohort over a 25-year time span. Using three cohorts of emerging adults (1982, n?=?189; 2007, n?=?188; and 2010, n?=?79) and a subsample of the 1982 cohort followed across 25?years (n?=?83), the findings indicated that well-being declined over time, possibly due to historical influences rather than changes associated with aging. Well-being was similarly predicted by religiosity, relationship status, and financial status across cohorts. Longitudinal analyses indicated that earlier religiosity was inversely associated with later financial status and later financial status was associated with higher well-being.     

Genomic Counseling: Next Generation Counseling

Personalized medicine continues to expand with the development and increasing use of genome-based testing. While these advances present new opportunities for diagnosis and risk assessment, they also present challenges to clinical delivery. Genetic counselors will play an important role in ushering in this new era of testing; however, it will warrant a shift from traditional genetic counseling to “genomic counseling.” This shift will be marked by a move from reactive genetic testing for diagnosis of primarily single-gene diseases to proactive genome-based testing for multiple complex diseases for the purpose of disease prevention. It will also require discussion of risk information for a number of diseases, some of which may have low relative risks or weak associations, and thus, may not substantially impact clinical care. Additionally, genomic counselors will expand their roles, particularly in the area of health promotion to reduce disease risk. This additional role will require a style of counseling that is more directive than traditional counseling and require greater knowledge about risk reducing behaviors and disease screening.     

Classifying Married Adults Diagnosed With Alpha-1 Antitrypsin Deficiency Based on Spousal Communication Patterns Using Latent Class Analysis: Insights for Intervention

Married adults are increasingly exposed to test results that indicate an increased genetic risk for adult-onset conditions. For example, a SERPINA1 mutation, associated with alpha-1 antitrypsin deficiency (AATD), predisposes affected individuals to diseases such as chronic obstructive pulmonary disease (COPD) and cancer, which are often detected in adulthood. Married adults are likely to discuss genetic test results with their spouses, and interpersonal research suggests that spouses’ communication patterns differ. Latent class analysis was used to identify subgroups of spousal communication patterns about AATD results from a sample of married adults in the Alpha-1 Research Registry (N?=?130). A five-class model was identified, and the subgroups were consistent with existing spousal-communication typologies. This study also showed that genetic beliefs (e.g., genetic stigma), emotions, and experiences (e.g., insurance difficulties) covaried with membership in particular subgroups. Understanding these differences can serve as the foundation for the creation of effective, targeted communications interventions to address the specific needs and conversational patterns of different kinds of couples.     

Child Perceptions of Parental Care and Overprotection in Children with Cancer and Healthy Children

The primary aims of this study were to: (a) examine child perceptions of overprotection; and (b) explore how these perceptions relate to child health and adjustment. Children with a prior diagnosis of cancer (n = 205) and children without a history of serious illness (n = 76) reported on parental overprotective and caring behaviors. Children with cancer were recruited from one of four strata based on the elapsed time since their cancer diagnosis (1–6 months; 6–24 months; 2–5 years; >5 years) Children also reported on symptoms of depression, anxiety, and posttraumatic stress. Children with cancer did not differ from healthy children in their perceptions of parental care or overprotection. Child distress was more strongly related to perceptions of care and overprotection than child’s health status. Children with cancer do not report their parents approach to care and protection differently than children without a cancer history. These findings mirror prior research examining parental perceptions of overprotection and suggest that, despite the challenges of parenting a child with serious illness, parental protection is not significantly altered.     

REARRANGING NATURALLY OCCURRING CONTINGENCIES TO INCREASE DESIRABLE BEHAVIOR IN A TODDLER CLASSROOM

Toddlers often display problem behavior during transitions. We rearranged naturally occurring events in a toddler classroom to promote more desirable classroom behavior during transitions to meals. In the intervention condition, teachers transitioned each child to meals only when that child was seated on a play mat (a requisite for engagement in teacher‐led play activities). In the reversal condition, teachers selected each child to transition when that child was by the barrier to the meal area (a practice commonly observed under natural conditions). The intervention increased the mean percentage of intervals when children were on the play mat and decreased the percentage of intervals when children were by the barrier. Individual child data show positive outcomes for five of six children. Results are discussed in terms of the positive effects of small manipulations to existing contingencies on classroom behavior as well as their potential influence on the adoptability of classroom interventions.

Yes,But Are They Happy? Effects of Trait Self‐Control on Affective Well‐Being and Life Satisfaction

Does trait self‐control (TSC) predict affective well‐being and life satisfaction—positively, negatively, or not? We conducted three studies (Study 1: N = 414, 64% female, M_age = 35.0 years; Study 2: N = 208, 66% female, M_age = 25.24 years; Study 3: N = 234, 61% female, M_age = 34.53 years). The key predictor was TSC, with affective well‐being and life satisfaction ratings as key outcomes. Potential explanatory constructs including goal conflict, goal balancing, and emotional distress also were investigated. TSC is positively related to affective well‐being and life satisfaction, and managing goal conflict is a key as to why. All studies, moreover, showed that the effect of TSC on life satisfaction is at least partially mediated by affect. Study 1's correlational study established the effect. Study 2's experience sampling approach demonstrated that compared to those low in TSC, those high in TSC experience higher levels of momentary affect even as they experience desire, an effect partially mediated through experiencing lower conflict and emotional distress. Study 3 found evidence for the proposed mechanism—that TSC may boost well‐being by helping people avoid frequent conflict and balance vice‐virtue conflicts by favoring virtues. Self‐control positively contributes to happiness through avoiding and dealing with motivational conflict.     

Dispositional Attachment Orientations,Contextual Variations in Attachment Security,and Compassion Fatigue Among Volunteers Working With Traumatized Individuals

In the present article, we report a series of studies examining the links between attachment orientations and compassion fatigue among volunteers working with traumatized individuals. Participants were volunteers in several trauma‐related organizations, ranging in age from 18 to 69 years. In Study 1 (N = 148), we examined associations between self‐reports of attachment insecurities and compassion fatigue. In Study 2 (N = 54), we used a diary design to assess attachment‐related differences in emotional reactions to actual helping encounters over a 2‐month period. In Study 3 (N = 108), we examined the effects of the experimental enhancement of attachment security (security priming) on reactions to a hypothetical helping encounter. As expected, attachment insecurities, either anxiety or avoidance, were associated with heightened compassion fatigue. Moreover, security priming reduced compassion fatigue in response to a hypothetical helping encounter. These findings underscore the relevance of attachment theory for understanding and preventing compassion fatigue.
