Neurobiological and memory models of risky decision making in adolescents versus young adults

Predictions of fuzzy-trace theory and neurobiological approaches are examined regarding risk taking in a classic decision-making task--the framing task--as well as in the context of real-life risk taking. We report the 1st study of framing effects in adolescents versus adults, varying risk and reward, and relate choices to individual differences, sexual behavior, and behavioral intentions. As predicted by fuzzy-trace theory, adolescents modulated risk taking according to risk and reward. Adults showed standard framing, reflecting greater emphasis on gist-based (qualitative) reasoning, but adolescents displayed reverse framing when potential gains for risk taking were high, reflecting greater emphasis on verbatim-based (quantitative) reasoning. Reverse framing signals a different way of thinking compared with standard framing (reverse framing also differs from simply choosing the risky option). Measures of verbatim- and gist-based reasoning about risk, sensation seeking, behavioral activation, and inhibition were used to extract dimensions of risk proneness: Sensation seeking increased and then decreased, whereas inhibition increased from early adolescence to young adulthood, predicted by neurobiological theories. Two additional dimensions, verbatim- and gist-based reasoning about risk, loaded separately and predicted unique variance in risk taking. Importantly, framing responses predicted real-life risk taking. Reasoning was the most consistent predictor of real-life risk taking: (a) Intentions to have sex, sexual behavior, and number of partners decreased when gist-based reasoning was triggered by retrieval cues in questions about perceived risk, whereas (b) intentions to have sex and number of partners increased when verbatim-based reasoning was triggered by different retrieval cues in questions about perceived risk.     

Gender Bias in Leader Selection? Evidence from a Hiring Simulation Study

The present research investigated factors that might affect gender discrimination in a hiring simulation context from the perspectives of social role theory and the shifting standards model. Specifically, the experimental study investigated whether gender biases are evident in the screening and hiring stage of the personnel selection process depending on the applicants?? social role and evaluators?? gender. A sample of German undergraduate business students (54 women, 53 men) was asked to make a personnel selection decision (short-listing or hiring) about a fictitious applicant (man or woman) in a specific role (leader or non-leader) for a managerial position. Consistent with social role theory??s assumption that social role information is more influential than gender information, participants selected applicants described as leaders over applicants described as non-leaders, regardless of applicant gender. In addition, in the presence of role information, female applicants portrayed as leaders were similarly short-listed and hired as male applicants with the same credentials. In the absence of role information, female applicants were similarly short-listed as male applicants; however, male applicants were hired over female applicants, albeit by male participants only. This is consistent with the shifting standards model??s assumption that group members are held to a higher standard to confirm traits on which they are perceived to be deficient: Male participants hired female applicants portrayed as non-leaders with less certainty than their male counterparts possibly due to higher confirmatory standards for leadership ability in women than men. The research and practice implications of these results are discussed.     

Physical activity and cognitive function in a cross-section of younger and older community-dwelling individuals.

Previous reports have indicated a small, positive relationship between physical activity and cognition. However, the majority of research has focused on older adults, with few studies examining this relationship during earlier periods of the life span. This study examined the relationship of physical activity to cognition in a cross-section of 241 community-dwelling individuals 15-71 years of age with a task requiring variable amounts of executive control. Data were analyzed with multiple regression, which controlled for age, sex, and IQ. Participants reported their physical activity behavior and were tested for reaction time (RT) and response accuracy on congruent and incongruent conditions of a flanker task, which manipulates interference control. After controlling for confounding variables, an age-related slowing of RT was observed during both congruent and incongruent flanker conditions. However, physical activity was associated with faster RT during these conditions, regardless of age. Response accuracy findings indicated that increased physical activity was associated with better performance only during the incongruent condition for the older cohort. Findings suggest that physical activity may be beneficial to both general and selective aspects of cognition, particularly among older adults.     

Boundary Considerations Between Doctoral Students and Master's Students

Counselor educators have a responsibility to teach students about boundary issues and multiple relationships. In addition to counselor–client concerns, there has been increased attention to faculty–student multiple relationships. Like faculty, doctoral students in counselor education programs often engage in roles with master's‐level students in which they hold a position of authority. This article reviews the professional literature on multiple relationships and boundary issues within counselor preparation programs and applies the research to boundary considerations between graduate students. Potentially fruitful areas for research are also suggested.     

Perceptions Among Child Welfare Staff when Modifying A Child Mental Health Intervention to be Implemented in Child Welfare Services

In order to increase access to child mental health evidence‐based interventions (EBIs) for vulnerable and hard‐to‐engage families involved in the child welfare (CW) system, innovative approaches coupled with input from service providers are needed. One potential solution involves utilizing task‐shifting strategies and implementation science theoretical frameworks to implement such EBIs in CW settings. This study examined perceptions among CW staff who were members of a collaborative advisory board involved in the implementation of the 4Rs and 2Ss Strengthening Families Program (4R2S) in CW placement prevention settings, utilizing task‐shifting strategies and the Practical, Robust, Implementation, and Sustainability Model. Advisory board members reported difficulties in engaging families, heavy workloads, and conflicting implementation initiatives. While 4R2S was perceived as generally aligned with their organization's mission, modifications to the intervention and to agency procedures were recommended to promote implementation success. Suggested modifications to the existing 4R2S training and supervision are discussed. Findings underscore the importance of understanding the experiences of CW service providers, which can inform future efforts to implement child mental health EBIs in CW services.     

Contingency awareness in a symptom learning paradigm: necessary but not sufficient?

In previous studies, we found that bodily symptoms can be learned in a differential conditioning paradigm, using odors as conditioned stimuli (CSs) and CO2-enriched air as unconditioned stimulus (US). However, this only occurred when the odor CS had a negative valence (a selective conditioning effect), and tended to be more pronounced in persons scoring high for Negative Affectivity (NA). This paper considers the necessity and/or sufficiency of awareness of the CS-US contingency in three studies using this paradigm. The relation between contingency awareness and the selective conditioning effect, and between contingency awareness and NA was also considered. Both self reported symptoms and respiratory physiology served as dependent variables. A learning effect on symptoms was found only for participants aware of the CS-US contingency, but not all participants reporting contingency awareness showed a learning effect. No conditioning effects appeared on the physiological measures. Also contingency awareness did not account for the selective conditioning effect, and did not interact with NA. Overall, the necessity but insufficiency hypotheses can only be withhold for group data and not for individual data.     

Increases in manic symptoms after life events involving goal attainment

Bipolar disorder has been conceptualized as an outcome of dysregulation in the behavioral activation system (BAS), a brain system that regulates goal-directed activity. On the basis of the BAS model, the authors hypothesized that life events involving goal attainment would promote manic symptoms in bipolar individuals. The authors followed 43 bipolar I individuals monthly with standardized symptom severity assessments (the Modified Hamilton Rating Scale for Depression and the Bech-Rafaelsen Mania Rating Scale). Life events were assessed using the Goal Attainment and Positivity scales of the Life Events and Difficulties Schedule. As hypothesized, manic symptoms increased in the 2 months following goal-attainment events, but depressed symptoms were not changed following goal-attainment events. These results are congruent with a series of recent polarity-specific findings.     

A score method of constructing asymmetric confidence intervals for the mean of a rating scale item

This article presents a generalization of the Score method of constructing confidence intervals for the population proportion (E. B. Wilson, 1927) to the case of the population mean of a rating scale item. A simulation study was conducted to assess the properties of the Score confidence interval in relation to the traditional Wald (A. Wald, 1943) confidence interval under a variety of conditions, including sample size, number of response options, extremeness of the population mean, and kurtosis of the response distribution. The results of the simulation study indicated that the Score interval usually outperformed the Wald interval, suggesting that the Score interval is a viable method of constructing confidence intervals for the population mean of a rating scale item.     

Distance-Delivered Parent Training for Childhood Disruptive Behavior (Strongest Families™): a Randomized Controlled Trial and Economic Analysis

Disruptive behavior disorders are prevalent in youth, yet most children with disruptive behavior do not have access to timely, effective treatment. Distance-delivered service (e.g., via telephone, Internet) can overcome several barriers to care. This study tested the effectiveness of a 12-week parent training program, Strongest Families? Parenting the Active Child, delivered via written material, skill-based videos, and telephone coaching sessions, as compared to usual care in reducing child externalizing behavior. Participants were 172 primary caregivers of a 6- to 12-year-old (29% girls; M age?=?8.5 years) recruited from community children’s mental health clinics. Participants were randomized to either Strongest Families? or usual care and completed measures of child externalizing behavior, parenting practices, parent distress, and intervention services consumed at baseline and 5-, 10-, 16-, and 22-months post-baseline. Growth curve analysis showed significant reductions in externalizing behavior in both conditions over time. Improvements were significantly greater at 10 months in the Strongest Families? condition (d =?0.43). At 22 months, however, the differences were not significant and small in magnitude (d =??0.05). The intervention decreased inconsistent discipline significantly more than usual care. Parents in both conditions showed significant reductions in distress. We also conducted a cost-effectiveness analysis to assess the value for money of the Strongest Families? program versus usual care. Distance parent training is a promising way to increase access to, and reduce costs associated with, mental health care for families with a child with disruptive behavior.
