Different early rearing experiences have long‐term effects on cortical organization in captive chimpanzees (Pan troglodytes)

Consequences of rearing history in chimpanzees (Pan troglodytes) have been explored in relation to behavioral abnormalities and cognition; however, little is known about the effects of rearing conditions on anatomical brain development. Human studies have revealed that experiences of maltreatment and neglect during infancy and childhood can have detrimental effects on brain development and cognition. In this study, we evaluated the effects of early rearing experience on brain morphology in 92 captive chimpanzees (ages 11–43) who were either reared by their mothers (n = 46) or in a nursery (n = 46) with age‐group peers. Magnetic resonance brain images were analyzed with a processing program (BrainVISA) that extracts cortical sulci. We obtained various measurements from 11 sulci located throughout the brain, as well as whole brain gyrification and white and grey matter volumes. We found that mother‐reared chimpanzees have greater global white‐to‐grey matter volume, more cortical folding and thinner grey matter within the cortical folds than nursery‐reared animals. The findings reported here are the first to demonstrate that differences in early rearing conditions have significant consequences on brain morphology in chimpanzees and suggests potential differences in the development of white matter expansion and myelination.     

Using Baby Books to Increase New Mothers' Self‐Efficacy and Improve Toddler Language Development

Maternal self‐efficacy (MSE) has been shown to be important, yet little is known about how it develops over time and whether increasing knowledge about child development and parenting results in feeling more efficacious, especially for first‐time mothers. Furthermore, research is lacking about whether increased maternal self‐efficacy results in better child outcomes such as more receptive and expressive language. Using a randomized three‐group design, this study explores whether educational books, embedded with information about typical child development and optimal parenting, increase MSE for women over the first year and a half of motherhood and whether these increases result in better language skills for children at 18 months of age. Hierarchical linear model analyses show that MSE starts high and remains high and that providing educational books further increases the development of MSE. Increases in MSE have a positive impact on children's language skills, as does providing books, irrespective of educational content. These findings support the importance of MSE and demonstrate an inexpensive way to increase MSE and improve child outcomes. Copyright © 2013 John Wiley & Sons, Ltd.     

The attribution of value-based attentional priority in individuals with depressive symptoms

The capture of attention by stimuli previously associated with reward has been demonstrated across a wide range of studies. Such value-based attentional priority appears to be robust, and cases where reward feedback fails to modulate subsequent attention have not been reported. However, individuals differ in their sensitivity to external rewards, and such sensitivity is abnormally blunted in depression. Here, we show that depressive symptomology is accompanied by insensitivity to value-based attentional bias. We replicate attentional capture by stimuli previously associated with reward in a control sample and show that these same reward-related stimuli do not capture attention in individuals experiencing symptoms of depression. This sharp contrast in performance indicates that value-based attentional biases depend on the normal functioning of the brain's reward system and suggests that a failure to preferentially attend to reward-related information may play a role in the experience of depression.     

Resilience to discrimination stress across ethnic identity stages of development

Ethnic identity development may increase resilience to discrimination and prejudice, which are often common and stressful for ethnic minority adolescents. Based on ethnic identity development theory and resilience theory, we hypothesize that under high discrimination stress, ethnic affirmation and ethnic identity stage will have protective moderating effects on self‐esteem and depressive symptoms. A cross‐sectional self‐report study with 125 ethnic minority adolescents (13–18 years) found that ethnic affirmation (p < .05) had protective effects on depressive symptoms (p < .05) and protective‐enhancing effects on self‐esteem at high levels of discrimination stress. Achieved ethnic identity stage (p < .05) had protective‐stabilizing effects on self‐esteem at high discrimination stress. Our findings demonstrate that the protective elements of ethnic identity are feeling positive about one's ethnic group, having learned about one's history, and having resolved conflicts about one's ethnic group.     

Examining Spirituality and Sense of Calling in Counseling Students

This study explored the link between counseling students’ spiritual well‐being and sense of calling to the profession. A final sample of 415 counseling students demonstrated significant spiritual well‐being (religious and existential) and a strong sense of calling to the counseling profession. Results also indicated that spiritual well‐being was predictive of students’ sense of calling to the profession. Implications for counselor training are discussed.     

Memory for surface features of unfamiliar melodies: independent effects of changes in pitch and tempo

A melody’s identity is determined by relations between consecutive tones in terms of pitch and duration, whereas surface features (i.e., pitch level or key, tempo, and timbre) are irrelevant. Although surface features of highly familiar recordings are encoded into memory, little is known about listeners’ mental representations of melodies heard once or twice. It is also unknown whether musical pitch is represented additively or interactively with temporal information. In two experiments, listeners heard unfamiliar melodies twice in an initial exposure phase. In a subsequent test phase, they heard the same (old) melodies interspersed with new melodies. Some of the old melodies were shifted in key, tempo, or key and tempo. Listeners’ task was to rate how well they recognized each melody from the exposure phase while ignoring changes in key and tempo. Recognition ratings were higher for old melodies that stayed the same compared to those that were shifted in key or tempo, and detrimental effects of key and tempo changes were additive in between-subjects (Experiment 1) and within-subjects (Experiment 2) designs. The results confirm that surface features are remembered for melodies heard only twice. They also imply that key and tempo are processed and stored independently.     

Young Offenders’ Emotion Recognition Dysfunction Across Emotion Intensities: Explaining Variation Using Psychopathic Traits,Conduct Disorder and Offense Severity

Antisocial individuals have problems recognizing negative emotions (e.g. Marsh & Blair in Neuroscience and Biobehavioral Reviews 32:454–465, 2009); however, due to issues with sampling and different methods used, previous findings have been varied. Sixty-three male young offenders and 37 age-, IQ- and socio-economic status-matched male controls completed a facial emotion recognition task, which measures recognition of happiness, sadness, fear, anger, disgust, and surprise and neutral expressions across 4 emotional intensities. Conduct disorder (YSR), and psychopathic and callous/unemotional traits (YPI) were measured, and offenders’ offense data were taken from the Youth Offending Service’s case files. Relative to controls, offenders were significantly worse at identifying sadness, low intensity disgust and high intensity fear. A significant interaction for anger was also observed, with offenders showing reduced low- but increased high-intensity anger recognition in comparison with controls. Within the young offenders levels of conduct disorder and psychopathic traits explained variation in sadness and disgust recognition, whereas offense severity explained variation in anger recognition. These results suggest that antisocial youths show specific problems in recognizing negative emotions and support the use of targeted emotion recognition interventions for problematic behavior.     

Ward v. Wilbanks: Students Respond

Ward v. Wilbanks is the most important legal case for the profession of counseling in the last 25 years. This qualitative research used general content analysis to examine master's‐level counseling students’ responses to the Ward v. Wilbanks case. Emergent themes from data analysis include (a) the role of gatekeeping; (b) Julea Ward and Eastern Michigan University: inflexible and uncompromising; (c) Ward v. Wilbanks: confusion, complexity, and certainty; and (d) personal values, professional values, and the ACA Code of Ethics (American Counseling Association, 2005 ).     

Diagnostic Exome Sequencing Identifies Two Novel IQSEC2 Mutations Associated with X-Linked Intellectual Disability with Seizures: Implications for Genetic Counseling and Clinical Diagnosis

Intellectual disability is a heterogeneous disorder with a wide phenotypic spectrum. Over 1,700 OMIM genes have been associated with this condition, many of which reside on the X-chromosome. The IQSEC2 gene is located on chromosome Xp11.22 and is known to play a significant role in the maintenance and homeostasis of the brain. Mutations in IQSEC2 have been historically associated with nonsyndromic X-linked intellectual disability. Case reports of affected probands show phenotypic overlap with conditions associated with pathogenic MECP2, FOXG1, CDKL5, and MEF2C gene mutations. Affected individuals, however, have also been identified as presenting with additional clinical features including seizures, autistic-behavior, psychiatric problems, and delayed language skills. To our knowledge, only 5 deleterious mutations and 2 intragenic duplications have been previously reported in IQSEC2. Here we report two novel IQSEC2 de novo truncating mutations identified through diagnostic exome sequencing in two severely affected unrelated male probands manifesting developmental delay, seizures, hypotonia, plagiocephaly, and abnormal MRI findings. Overall, diagnostic exome sequencing established a molecular diagnosis for two patients in whom traditional testing methods were uninformative while expanding on the mutational and phenotypic spectrum. In addition, our data suggests that IQSEC2 may be more common than previously appreciated, accounting for approximately 9 % (2/22) of positive findings among patients with seizures referred for diagnostic exome sequencing. Further, these data supports recently published data suggesting that IQSEC2 plays a more significant role in the development of X-linked intellectual disability with seizures than previously anticipated.
