The perception of a face is no more than the sum of its parts

When you see a person's face, how do you go about combining his or her facial features to make a decision about who that person is? Most current theories of face perception assert that the ability to recognize a human face is not simply the result of an independent analysis of individual features, but instead involves a holistic coding of the relationships among features. This coding is thought to enhance people's ability to recognize a face beyond what would be expected if each feature were shown in isolation. In the study reported here, we explicitly tested this idea by comparing human performance on facial-feature integration with that of an optimal Bayesian integrator. Contrary to the predictions of most current notions of face perception, our findings showed that human observers integrate facial features in a manner that is no better than would be predicted by their ability to use each individual feature when shown in isolation. That is, a face is perceived no better than the sum of its individual parts.     

Examining mental health symptoms in male and female incarcerated juveniles

Varying risk factors for both incarceration and mental health diagnoses have been identified for female juveniles, highlighting the need for gender-specific assessments and treatment protocols. The purpose of this study is to determine how the prevalence rates of mental health symptoms differ in male and female juvenile offenders. It was hypothesized that the prevalence rates would be greater for females than males. This study found significant differences between males and females on several clinical scales. These findings are consistent with past studies that have identified differences in mental health symptoms between genders.     

Bitter reproach or sweet revenge: cultural differences in response to racism

Culture has been shown to influence response styles. The authors conducted two studies to test the notion that African Americans would be more likely to respond to racism directly, whereas Asian Americans would be more likely to respond indirectly and therefore more subtly. Study 1 showed that Black women subjected to a racist comment from a confederate during an online interaction were more likely than Asian women to verbally reproach the perpetrator. These group differences were not present when the outcome measure was indirect responding--administration of good/bad jellybeans. Study 2 used an online format to demonstrate that Asian women were more likely than Black women to say they would not respond directly to a racist comment. This group difference in unwillingness to confront was significantly mediated by a goal of maintaining peace with their interaction partner. Implications of these findings for the study of discrimination, coping, and well-being are discussed.

Optimizing Engagement in Behavioral Parent Training: Progress Toward a Technology-Enhanced Treatment Model

Low-income families are more likely to have a child with an early-onset Behavior Disorder (BD); yet, socioeconomic strain challenges engagement in Behavioral Parent Training (BPT). This study follows a promising pilot to further examine the potential to cost-effectively improve low-income families’ engagement in and the efficiency of BPT. Low-income families were randomized to (a) Helping the Noncompliant Child (HNC; McMahon & Forehand, 2003), a weekly, mastery-based BPT program that includes both the parent and child or (b) Technology-Enhanced HNC (TE-HNC), which includes all of the standard HNC components plus a parent mobile application and therapist web portal that provide between-session monitoring, modeling, and coaching of parent skill use with the goal of improved engagement in the context of financial strain. Relative to HNC, TE-HNC families had greater homework compliance and mid-week call participation. TE-HNC completers also required fewer weeks to achieve skill mastery and, in turn, to complete treatment than those in HNC without compromising parent satisfaction with treatment; yet, session attendance and completion were not different between groups. Future directions and clinical implications are discussed.     

A Systematic Review of Sleep Associations in Parents and Children

This systematic review aimed to examine sleep associations in a) typically developing children and their parents, and b) children with neurodevelopmental disorders and their parents. Literature search was conducted on PubMed, PsycINFO, EMBASE and Scopus databases for articles examining sleep associations between parents and children. Thirty studies were included in the final review. Based on the first aim, sleep associations between parents and typically developing children were observed for sleep quality, sleep duration and sleep efficiency. However, evidence for associations between sleepiness levels in parents and children and sleep schedules related to bedtime or waketime was limited. Based on the second aim, children with neurodevelopmental disorders and their parents reported greater sleep disturbances in comparison to typically developing children and their parents. The review concluded that sleep in parents and children is interrelated across a number of sleep parameters. It also revealed some preliminary evidence on bidirectionality in parent-child sleep, which warrants further examination. The review highlights the need to examine the mediating role of environmental factors on the interactions between parent-child sleep. Rigorous, longitudinal designs should be employed to explore the pathways through which parents may impact their children’s sleep and functioning and vice-versa.

Bilateral Transcranial Direct Stimulation Over the Primary Motor Cortex Alters Motor Modularity of Multiple Muscles

Abstract

Transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) has been demonstrated to modulate the motor performance of both healthy individuals and patients with neuromuscular disorders. However, the effect of tDCS on motor control of multiple muscles, which is a prerequisite to change in motor performance, is currently unknown. Using dimensionality reduction analysis, we investigated whether bilateral tDCS over M1 modulates the coordinated activity of 12 muscles. Fifteen healthy men participated in this randomized, double-blind crossover study. Each participant received a 20-min sham and 2-mA stimulation bilaterally over M1 (anode on the right M1 and cathode on the left M1), with a minimum washout period of 4?days. Muscle activation and end-point kinematics were evaluated during a task where participants reached out to a marked target with non-dominant hand as fast as possible, before and immediately after tDCS application. We found decreased similarity in motor modularity and significant changes in muscle activation in a specific motor module, particularly when reaching out to a target placed within arm’s length and improved smoothness index of movement only following 2-mA stimulation. These findings indicate that clinicians and researchers need to consider the simultaneous effect of bilateral tDCS over M1 on multiple muscles when they establish tDCS protocol to change in motor performance of patients with neuromuscular deficits.
