Adult age differences in frontostriatal representation of prediction error but not reward outcome

Emerging evidence from decision neuroscience suggests that although younger and older adults show similar frontostriatal representations of reward magnitude, older adults often show deficits in feedback-driven reinforcement learning. In the present study, healthy adults completed reward-based tasks that did or did not depend on probabilistic learning, while undergoing functional neuroimaging. We observed reductions in the frontostriatal representation of prediction errors during probabilistic learning in older adults. In contrast, we found evidence for stability across adulthood in the representation of reward outcome in a task that did not require learning. Together, the results identify changes across adulthood in the dynamic coding of relational representations of feedback, in spite of preserved reward sensitivity in old age. Overall, the results suggest that the neural representation of prediction error, but not reward outcome, is reduced in old age. These findings reveal a potential dissociation between cognition and motivation with age and identify a potential mechanism for explaining changes in learning-dependent decision making in old adulthood.     

Expansion of Genetic Services Utilizing a General Genetic Counseling Clinic

We established a general genetic counseling clinic (GCC) to help reduce long wait times for new patient appointments and to enhance services for a subset of patients. Genetic counselors, who are licensed in Tennessee, were the primary providers and MD geneticists served as medical advisors. This article describes the clinic referral sources, reasons for referral and patient dispositions following their GCC visit(s). We obtained patients by triaging referrals made to our medical genetics division. Over 24 months, our GCC provided timely visits for 321 patients, allowing the MD geneticists to focus on patients needing a clinical exam and/or complex medical management. Following their GCC visit(s), over 80 % of patients did not need additional appointments with an MD geneticist. The GCC allowed the genetic counselor to spend more time with patients than is possible in our traditional medical genetics clinic. Patient satisfaction surveys (n?=?30) were very positive overall concerning the care provided. Added benefits for the genetic counselors were increased professional responsibility, autonomy and visibility as health care providers. We conclude that genetic counselors are accepted as health care providers by patients and referring providers for a subset of clinical genetics cases. A GCC can expand genetic services, complement more traditional genetic clinic models and utilize the strengths of the genetic counselor health care provider.     

The Impact of Racial Microaggressions on Mental Health: Counseling Implications for Clients of Color

This study examined the relationship between racial microaggressions (subtle and unintentional forms of racial discrimination) and mental health. Results from a large sample (N = 506) indicated that higher frequencies of racial microaggressions negatively predicted participants' mental health and that racial microaggressions were significantly correlated with depressive symptoms and negative affect. Differences in the types of microaggressions experienced by various racial groups (Asian, Latina/o, Black, White, and multiracial) and counseling implications are discussed.     

Bullying and cyberbullying in adulthood and the workplace

Two studies generated profiles of cyberbullying/cyberincivility and traditional bullying/incivility in adults, particularly within the workplace. In Study 1, 20% of 3,699 participants had the majority of cyberbullying victimization and 7.5% had the majority of traditional bullying victimization occur in adulthood, with 30% saying they were bullied at work. Relationships between bullying and negative outcomes were found. Because of the clear evidence of bullying and cyberbullying in the workplace in Study 1, Study 2 addressed the relationship of these constructs to workplace incivility. Workplace face-to-face incivility and bullying were related among 321 participants, as were workplace cyberbullying and cyberincivility. Face-to-face incivility was more common than online incivility, face-to-face bullying, or online bullying, yet all four behaviors were associated with negative outcomes. Differences in intentionality, acceptability, and severity were observed, with workplace face-to-face bullying perceived as the most severe and having the greatest intentionality to harm. These results emphasize the importance of studying bullying among adults, and highlight the conceptual independence of bullying and incivility. Correlates of workplace aggression are discussed using job demands-resources theory.     

Precues’ elevation of sensitivity is not only preattentive,but largely monocular

Visual sensitivity can be heightened in the vicinity of an appropriate precue. Experiments with multiple, noninformative precues suggest that this facilitation should not be attributed to focal attention. The number of simultaneously appearing precues seems to be irrelevant; contrast thresholds are lowest for targets that appear in a precued position. Here we report that precues become less effective when they and the target are delivered to different eyes. We conclude that the mechanism responsible for such heightened sensitivity has largely monocular input.     

Is early word-form processing stress-full? How natural variability supports recognition

In a series of studies, we examined how mothers naturally stress words across multiple mentions in speech to their infants and how this marking influences infants’ recognition of words in fluent speech. We first collected samples of mothers’ infant-directed speech using a technique that induced multiple repetitions of target words. Acoustic analyses revealed that mothers systematically alternated between emphatic and nonemphatic stress when talking to their infants. Using the headturn preference procedure, we then tested 7.5-month-old infants on their ability to detect familiarized bisyllabic words in fluent speech. Stress of target words (emphatic and nonemphatic) was systematically varied across familiarization and recognition phases of four experiments. Results indicated that, although infants generally prefer listening to words produced with emphatic stress, recognition was enhanced when the degree of emphatic stress at familiarization matched the degree of emphatic stress at recognition.     

Variety‐Seeking and Perceived Expertise

People often infer expertise from the choice of unique, rare, or sophisticated options. But might mere variety‐seeking also serve as a signal of expertise, and if so, how? Six studies show that the relationship between variety‐seeking and perceived expertise is not unidirectional and depends on the perceiver's own level of expertise. Category experts perceive lower variety‐seeking as indicative of discernment, which in turn increases perceived expertise in that category. Consequently, experts choose less variety to portray themselves as experts. In contrast, novices perceive high variety‐seeking as indicative of category breadth knowledge, which in turn increases their perception of category expertise. Consequently, novices choose more variety to portray themselves as experts. The findings make novel theoretical contributions to research on variety‐seeking, consumer expertise, and social perception, as well as practical contributions for marketers of product assortments and bundles.
