The role of rhythm in perceiving speech in noise: a comparison of percussionists,vocalists and non-musicians

The natural rhythms of speech help a listener follow what is being said, especially in noisy conditions. There is increasing evidence for links between rhythm abilities and language skills; however, the role of rhythm-related expertise in perceiving speech in noise is unknown. The present study assesses musical competence (rhythmic and melodic discrimination), speech-in-noise perception and auditory working memory in young adult percussionists, vocalists and non-musicians. Outcomes reveal that better ability to discriminate rhythms is associated with better sentence-in-noise (but not words-in-noise) perception across all participants. These outcomes suggest that sensitivity to rhythm helps a listener understand unfolding speech patterns in degraded listening conditions, and that observations of a “musician advantage” for speech-in-noise perception may be mediated in part by superior rhythm skills.     

Bilingual enhancements have no socioeconomic boundaries

To understand how socioeconomic status (SES) and bilingualism simultaneously operate on cognitive and sensory function, we examined executive control, language skills, and neural processing of sound in adolescents who differed in language experience (i.e. English monolingual or Spanish‐English bilingual) and level of maternal education (a proxy for SES). We hypothesized that experience communicating in two languages provides an enriched linguistic environment that can bolster neural precision in subcortical auditory processing which, in turn, enhances cognitive and linguistic function, regardless of the adolescent's socioeconomic standing. Consistent with this, we report that adolescent bilinguals of both low and high SES demonstrate more stable neural responses, stronger phonemic decoding skills, and heightened executive control, relative to their monolingual peers. These results support the argument that bilingualism can bolster cognitive and neural function in low‐SES children and suggest that strengthened neural response consistency provides a biological mechanism through which these enhancements occur.     

Practicing what we know: Multicultural counseling competence among clinical psychology trainees and experienced multicultural psychologists

Multicultural (MC) competence is considered a necessary skill for clinical and counseling psychologists; however, there is little to no research on the assessment of demonstrated multicultural counseling competence (DMCCC) of clinical psychology graduate students. In this study, we developed a MC assessment instrument to assess DMCCC of clinical psychology graduate students compared with MC-experienced psychologists. In addition, we assessed for differences between the endorsement of MC-appropriate strategies and actual use of these strategies in clinical practice, both by MC-experienced psychologists and clinical psychology students. Results revealed significant differences between the DMCCC of clinical psychology graduate students and MC-experienced psychologists. Significant differences also emerged between endorsement of strategies as multiculturally appropriate and likelihood of actual use of these strategies. Findings suggest that future training and competence models should incorporate participants' ability to not only identify multiculturally appropriate strategies but also use these strategies in therapy.     

We’ve Come a Long Way,Baby!: Evolution and Revolution in CBT with Youth

As the gold standard in psychotherapy with children and adolescents, cognitive behavioral therapy (CBT) earned its stripes through the years. CBT evolved from treating individual disorders with single protocols to embracing a modular and transdiagnostic approach. Despite this impressive evolution, CBT initiated a revolution that continues to provide services to patients in this new era. CBT must maintain momentum to fuel progress and drive clinical reform. In this article, the need for training and dissemination are discussed. Revolutionary practices and delivery methods are suggested. CBT continues to push the envelope of revolution by partnering with neuroscience to bridge the gap between brain and body. Integrating findings from neuroscience with CBT-spectrum approaches and non-traditional treatment formats provides theoretical flexibility and additional treatment options for clinicians. Culturally-friendly applications to treat diverse youth and the use of common modules from third wave approaches are suggested. The use of technology such as smartphones, computers, and videogames is encouraged. Offering treatment in non-traditional settings and formats such as CBT-based camp programs is also addressed.

A modified version of the unique cue theory accounts for olfactory compound processing in honeybees

We investigated the capability of honeybees to discriminate between single odorants, binary olfactory mixtures, and ternary olfactory mixtures in olfactory conditioning of the proboscis extension reflex. In Experiment 1, three single odorants (A+, B+, and C+) and three binary mixtures of these odors (AB+, AC+, and BC+) were reinforced while the ternary compound, consisting of all three odors (ABC-), was nonreinforced. In Experiment 2, only one single odorant (A+) and one binary olfactory compound (BC+) were reinforced while the ternary compound (ABC-) consisting of the single odor and the binary compound was nonreinforced. We studied whether bees can solve these problems and whether the course of differentiation can be predicted by the unique cue theory, a modified unique cue theory, or Pearce's configural theory. Honeybees were not able to differentiate reinforced from nonreinforced stimuli in Experiment 1. However, summation to ABC observed at the beginning of training contradicts the predictions of Pearce's configural theory. In Experiment 2, differentiation between the single odorant A and the ternary compound developed more easily than between the binary compound BC and ABC. This pattern of differentiation is in line with a modified unique cue theory and Pearce's configural theory. Summation to ABC at the beginning of training, however, again was at odds with Pearce's configural theory. Thus, olfactory compound processing in honeybees can best be explained by a modified unique cue theory.     

Self-regulation in error management training: emotion control and metacognition as mediators of performance effects

In error management training, participants are explicitly encouraged to make errors and learn from them. Error management training has frequently been shown to lead to better performance than conventional trainings that adopt an error avoidant approach. The present study investigated self-regulatory processes mediating this effect. Fifty-five volunteer students learned a computer program under 1 of 3 conditions: error avoidant training, error management training, or error management training supplemented with a metacognitive module. As predicted, both forms of error management training led to better transfer performance than did error avoidant training (d = 0.75). Mediation hypotheses were fully supported: Emotion control and metacognitive activity (from verbal protocols) mediated performance differences. These findings highlight the potential of promoting self-regulatory processing during training.     

Stability in schizophrenia symptoms over time: findings from the Mount Sinai Pilgrim Psychiatric Center Longitudinal Study

This study examined the stability of symptoms of schizophrenia over time, focusing on the stability of symptom structure. Symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS). The sample consisted of 215 chronic patients followed up for as long as 4 years. Exploratory factor analysis identified 6 factors. Several statistical techniques were used to examine the stability of these symptoms, including longitudinal confirmatory factor analysis. Low-to-moderate rank-order stability and high absolute stability of the factors were found, with the structure of the PANSS-assessed symptoms consistent over time. The results demonstrate that despite changes in the severity of symptoms in individual patients with schizophrenia, the factor structure and interrelatedness of symptoms have considerable stability over time.     

Predictors of subjective age before and after cataract surgery: conscientiousness makes a difference

This study contributes to research on subjective age by examining the interplay of felt age with health, functional limitations, and personality. Individuals undergoing cataract surgery (N=134; 38 to 92 years of age) provided data for an assessment period of 6 weeks surrounding their scheduled surgery. Conscientiousness and repeated measurements of health indicators, functional limitations, and felt age were included in the analyses. Results indicated that functional limitations may be more important to the construction of felt age than their underlying health-related causes. Moreover, conscientious participants felt younger before and after surgery. Their functional status was less dependent on health than the functional status of less conscientious participants. This moderator effect is discussed along with health-related pathways leading to felt age.     

Lesion analysis of the brain areas involved in language comprehension

The cortical regions of the brain traditionally associated with the comprehension of language are Wernicke's area and Broca's area. However, recent evidence suggests that other brain regions might also be involved in this complex process. This paper describes the opportunity to evaluate a large number of brain-injured patients to determine which lesioned brain areas might affect language comprehension. Sixty-four chronic left hemisphere stroke patients were evaluated on 11 subtests of the Curtiss-Yamada Comprehensive Language Evaluation - Receptive (CYCLE-R; Curtiss, S., & Yamada, J. (1988). Curtiss-Yamada Comprehensive Language Evaluation. Unpublished test, UCLA). Eight right hemisphere stroke patients and 15 neurologically normal older controls also participated. Patients were required to select a single line drawing from an array of three or four choices that best depicted the content of an auditorily-presented sentence. Patients' lesions obtained from structural neuroimaging were reconstructed onto templates and entered into a voxel-based lesion-symptom mapping (VLSM; Bates, E., Wilson, S., Saygin, A. P., Dick, F., Sereno, M., Knight, R. T., & Dronkers, N. F. (2003). Voxel-based lesion-symptom mapping. Nature Neuroscience, 6(5), 448-450.) analysis along with the behavioral data. VLSM is a brain-behavior mapping technique that evaluates the relationships between areas of injury and behavioral performance in all patients on a voxel-by-voxel basis, similar to the analysis of functional neuroimaging data. Results indicated that lesions to five left hemisphere brain regions affected performance on the CYCLE-R, including the posterior middle temporal gyrus and underlying white matter, the anterior superior temporal gyrus, the superior temporal sulcus and angular gyrus, mid-frontal cortex in Brodmann's area 46, and Brodmann's area 47 of the inferior frontal gyrus. Lesions to Broca's and Wernicke's areas were not found to significantly alter language comprehension on this particular measure. Further analysis suggested that the middle temporal gyrus may be more important for comprehension at the word level, while the other regions may play a greater role at the level of the sentence. These results are consistent with those seen in recent functional neuroimaging studies and offer complementary data in the effort to understand the brain areas underlying language comprehension.
