The perceived salience of errors can be influenced by individual-level motivational factors. Specifically, those who endorse a high degree of collectivism, a cultural value that emphasizes prioritization of interpersonal relationships, may find errors occurring in a social context to be more aversive than individuals who endorse collectivism to a lesser degree, resulting in upregulation of a neural correlate of error-monitoring, the error-related negativity (ERN). This study aimed to identify cultural variation in neural response to errors occurring in a social context in a sample of diverse adolescents. It was predicted that greater collectivism would be associated with enhanced neural response to errors occurring as part of a team. Participants were 95 Latinx (n = 35), Asian American (n = 20), and non-Latinx White (n = 40) adolescents (ages 13-17) who completed a go/no-go task while continuous electroencephalogram was recorded. The task included social (team) and non-social (individual) conditions. ERN was quantified using mean amplitude measures. Regression models demonstrated that collectivism modulated neural response to errors occurring in a social context, an effect that was most robust for Latinx adolescents. Understanding cultural variation in neural sensitivity to social context could inform understanding of both normative and maladaptive processes associated with self-regulation.

Reduction of telogen rate and increase of hair density in androgenetic alopecia by a cosmetic product: Results of a randomized, prospective, vehicle-controlled double-blind study in men.

J Cosmet Dermatol 2021 May 6. Epub 2021 May 6.

Department of Dermatology, Municipal Clinics Karlsruhe, Karlsruhe, Germany.

Background: Considerable parts of the global population are affected by androgenetic alopecia (AGA).

Aims: The efficacy of a foam containing nicotinic acid hexyl ester, polyphenols, zinc, glycine, and caffeine in comparison with a vehicle control foam was assessed in a double-blind vehicle-controlled study in men with AGA over 6 months.

Patients/methods: Sixty-two men with AGA were assigned either to the active ingredients (verum) or the vehicle group. They applied the products twice daily on affected scalp areas over 6 months. Automated phototrichograms were obtained at baseline, after 3 and 6 months. In addition, a clinical rating by a dermatologist and by the subjects themselves was documented using standardized questionnaires.

Results: The reduction of the telogen rate from T0 to T6 was significantly stronger in the verum group compared to the vehicle group. The reduction was significant from T0 to T3 and T6 in the verum group, but in the vehicle group only from T0 to T3, not to T6. Significantly increased hair density was noticed in both groups at all time points, but the change from T0 to T6 did not differ significantly between the groups. Cosmetic acceptance of the foam and its application regimen was generally good in both groups. Slight reddening and burning after application of verum in six cases was probably due to the presence of hexyl nicotinate.

Conclusion: The study demonstrated a reduction of the telogen rate by a cosmetic foam in men affected by AGA, indicating a benefit for cosmetic intervention against male pattern hair loss.

A commentary on establishing norms for error-related brain activity during the arrow flanker task among young adults.

Neuroimage 2021 07 4;234:117932. Epub 2021 Mar 4.

Department of Psychology, Brigham Young University, Provo, UT, USA; Neuroscience Center, Brigham Young University, Provo, UT, USA.

We suggest that a large data set for the error-related negativity (ERN) and error positivity (Pe) components of the scalp-recorded event-related brain potential (ERP) recently published as normative is not ready for such use in research and, especially, clinical application. Such efforts are challenged by an incomplete understanding of the functional significance of between-person differences in amplitudes and of nuisance factors that contribute to amplitude differences, a lack of standardization of methods, and the use of a convenience sample for the potentially normative database. To move ERPs toward standardization and useful norms, we encourage more research on the meaning of differences in ERN scores, including factors that influence between- and within-person variation, and the dissemination of protocols for data collection and processing.

Cultural Values Influence Relations Between Parent Emotion Socialization and Adolescents' Neural Responses to Peer Rejection.

Res Child Adolesc Psychopathol 2021 Jan 12. Epub 2021 Jan 12.

Department of Psychology, University of California, Los Angeles, CA, USA.

Adolescents' responses to negative social experiences can be influenced by parenting behaviors. This includes how parents react to their child's expression of emotions, an aspect of parenting referred to as emotion socialization. Emotion socialization may intersect with cultural values, particularly collectivism, a socially-relevant attitude that emphasizes the importance of interpersonal relationships. Examination of a neural measure called the feedback-related negativity (FRN), thought to reflect the degree to which feedback is experienced as aversive, could help elucidate neural contributions to and consequences of the role of collectivism in such family dynamics. Thus, this study examined whether adolescents' endorsement of collectivism moderated the association of parents' dismissive emotion socialization responses (called override responses) and FRN following peer rejection. A community sample of 83 Latinx (n = 32), Asian American (n = 20), and non-Latinx White (n = 31) adolescents ages 13-17 completed a computerized peer feedback task while continuous electroencephalogram was recorded. Their parents completed a battery of self-report questionnaires. Regression analyses demonstrated that adolescents' endorsement of collectivism moderated the association of override responses and FRN following peer rejection, such that FRN was enhanced as override responses increased for adolescents endorsing low and moderate levels of collectivism. Results suggest that there is cultural variation in the association of the emotion socialization strategy of override and adolescents' neural responses to socially-salient events. Findings have implications for parenting interventions designed to enhance adolescents' emotion regulation abilities.

A Diagnostic Biomarker for Pediatric Generalized Anxiety Disorder Using the Error-Related Negativity.

Child Psychiatry Hum Dev 2020 10;51(5):827-838

Department of Psychology, University of Michigan, 4250 Plymouth Road, Ann Arbor, MI, 48109-5766, USA.

The error-related negativity (ERN) is a negative deflection in the event-related potential following a mistake that is a putative biomarker of anxiety. The study assessed the ERN as a diagnostic biomarker using receiver operating characteristic (ROC) analyses in 96 cases with anxiety disorders (AD) and 96 matched healthy controls (HC) ages 8 to 18 years. Forty-one cases had generalized anxiety disorder (GAD); 55 cases had other anxiety disorders (OAD) without GAD. ERN amplitude was significantly increased in AD cases compared to HC. The area under the curve (AUC) in the ROC analysis was 0.64, indicating the ERN is an inadequate diagnostic test for AD altogether. The ERN was significantly increased in cases with either GAD or OAD compared to HC. The AUC in ROC analyses with GAD and OAD was 0.75 and 0.56, respectively, suggesting the ERN provides an adequate diagnostic test for GAD but not for OAD.
