Family emotion expressivity,emotion regulation,and the link to psychopathology: Examination across race

Research has established links between parental emotion socialization behaviours and youth emotional and psychological outcomes; however, no study has simultaneously compared these relations for White, Black, and Asian individuals. In this study, emerging adults identifying as White (n= 61), Black (n= 51), or Asian (n= 56) retrospectively reported on parents’ emotion socialization behaviours during childhood, existing emotion regulation (ER) skills, and current psychopathology symptoms. Asian participants reported fewer positive displays of emotions in their families during childhood than White and Black participants. Despite this difference, low expression of positive emotions in families during childhood did not relate to negative outcomes for Asian participants but was linked for White and Black participants. Overall, Asian participants reported more difficulties with ER than Black or White participants, and relations between ER difficulties and psychopathology varied by racial group. The findings emphasize the need to consider race when conducting research on emotion functioning with families and highlight emotion dysregulation as a potential treatment target for White, Black, and Asian individuals.     

A New Tactile Illusion: Temporal Limits on the Processing of Spatiotemporal Patterns

A novel illusion was observed when 12 tactile point-stimulators arranged in a circle were sequentially activated so that each quadrant was first traced in a clockwise manner, then counterclockwise, and again in a clockwise manner, after which the next quadrant was similarly traced. Under certain temporal conditions this stimulus pattern was experienced as a point moving through an overall circular path but looping inwardly about once per quadrant. The effects of variations in rate of presentation of such stimuli were investigated by having subjects make drawings of their perceptual experiences. Three skin surfaces were used (palm, fingers, and forearm), and all produced similar results except for lower confidence and reliability of drawings made from forearm stimulation. Pattern presentation rate, however, had a consistent and powerful effect, with the looping illusion most frequently observed at rates around 25 pattern points per s and with different perceptual organizations dominating as rates departed widely from this optimum. The illusory perceptual organizations were interpreted as compromises between past and present stimulation necessitated by the relative slowness of tactile processing of spatio-temporal patterns.     

The Best Years of Life: A Study in ranking

The relationship between temporal behavior (as measured by the method of reproduction) and the relative acquisition rate of discrimination-reversal learning was investigated in 52 sixth-grade students (22 boys, 30 girls).

The results indicate that (a) temporal performance tends to be less variable than learning performance, (b) a significant, negative correlation exists between mean time estimation scores and mean learning scores, (c) relatively fast learning is associated with relative overestimation of time, and (d) relatively slow learning is associated with relative underestimation of time. No sex differences were found.

These results are in contrast with results reported by Montare with adult Ss whose underestimation was associated with fast learning and overestimation with slow learning. It is theorized that perhaps these results represent a developmental pattern in learning which shifts from a predominance of inhibitory processes underlying relatively fast learning during childhood towards a predominance of excitatory processes necessary for relatively fast learning in adulthood.     

Trustworthiness Processing and Psychobiological Responses to Natural Disaster-Induced Distress in Adolescents

In this study, we examine the role of trust perceptions on psychological well-being and salivary cortisol levels of adolescents who were exposed to pervasive, noninterpersonal trauma, displacement, and relocation caused by Hurricane Katrina. Compared to demographically matched controls, affected adolescents reported higher perceptions of other people's trustworthiness, decreased externalizing behaviors, increased internalizing behaviors, greater desire for consolation from others, and lower cortisol activity. Follow-up analyses suggested that the relation between hurricane exposure and lower self-esteem might be mediated partly by increased trustworthiness perceptions. These results suggest that adolescents might respond to different types of stressors with varying patterns of distress and the manner in which the stressors alter trust processing might predict the development of internalizing or externalizing behaviors.     

Computerized Neurocognitive Testing in the Management of Sport-Related Concussion: An Update

Since the late nineties, computerized neurocognitive testing has become a central component of sport-related concussion (SRC) management at all levels of sport. In 2005, a review of the available evidence on the psychometric properties of four computerized neuropsychological test batteries concluded that the tests did not possess the necessary criteria to warrant clinical application. Since the publication of that review, several more computerized neurocognitive tests have entered the market place. The purpose of this review is to summarize the body of published studies on psychometric properties and clinical utility of computerized neurocognitive tests available for use in the assessment of SRC. A review of the literature from 2005 to 2013 was conducted to gather evidence of test-retest reliability and clinical validity of these instruments. Reviewed articles included both prospective and retrospective studies of primarily sport-based adult and pediatric samples. Summaries are provided regarding the available evidence of reliability and validity for the most commonly used computerized neurocognitive tests in sports settings.     

Walking on an Oscillating Treadmill: Strategies of Stride-Time Adaptation

Gains in mobility, balance, and gait quality have been observed in clinical populations after treadmill training. In our laboratory, we introduce healthy adults to treadmill training programs in an effort to boost their adaptive generalization skills. We hypothesized that some individuals are more naturally predisposed to gait adaptation than others. Stride-time data from 20 healthy adults were collected while they walked on a laterally oscillating treadmill for the first time. We predicted that the more plastic adapters would rapidly synchronize their stride frequencies to the treadmill's oscillation frequency. A treadmill mounted on a 6-degrees-of-freedom motion base platform was programmed to move laterally in a continuous, sinusoidal pattern for 20 min while participants walked at 1.1 m/s. Twenty-five percent of our participants showed a prolonged uninstructed entrained response. Those who did not entrain were still able to adapt to the novel locomotor challenge by applying various alternative strategies. Although entrainment was not required for adaptation, we report compelling evidence that the frequency of the support-surface motion influenced the adapted strategies of 80% of our participants.     

Step-down approach to behavioural weight loss treatment: a pilot of a randomised clinical trial

Background: In a stepped-down approach, patients begin with a more intensive treatment and are stepped down to a less intensive treatment based on achieving treatment goals. This study compared a standard behavioural weight loss programme (BWLP) to a stepped-down approach to treatment.

Methods: Fifty-two overweight/obese adults (Age: M?=?47?years, SD?=?13.5; female?=?67%) participated in an 18-week BWLP. Half of them were randomly assigned to be stepped down from weekly group meetings based on completion of weight loss goals (3%) every 6?weeks, while the other half remained in their groups regardless of weight loss.

Results: There was a significant difference favouring the BWLP in the proportion of participants who met or exceeded their 3% weight loss goal during the first six weeks. While not statistically significant by the end of treatment, the BWLP participants lost nearly 3% more body weight than stepped-down participants (SC?=?4.9% vs. BWLP?=?7.8%; p?=?.10). Greater self-monitoring was associated with increased likelihood of stepped-care eligibility and higher percent weight loss at the end of treatment (p?<?.01).

Conclusion: There was little evidence to support the efficacy of the stepped-down approach for behavioural weight loss treatment employed in this investigation.     

Validation of a TAI Short Form with an Adolescent Sample

Subjects who pretested high or low in hypnotic suggestibility took a creativity test either under hypnosis or in a waking state. All subjects made a global estimate of their general degree of creativity. Greater figural-spatial creativity was exhibited in the hypnosis condition than in the waking condition by both high and low suggestibles. Creativity self-reports were not corroborated by actual creative performance.     

Childhood as continuity and newness: generational succession understood according to the theological logic of the gift

This article seeks to understand, in a speculative way, the relationship between a new generation and the one preceding it. After having identified two opposite extremes – the ‘continuity thesis’ and the ‘discontinuity thesis’ – the article appropriates the logic of gift exchange to map out a mediating position. The fact that the practice of gift exchange is susceptible to criticism is subsequently noted, and two major lines of philosophical criticism are considered and related to the continuity thesis and the discontinuity thesis, respectively. The article then makes use of the work done by John Milbank to show that a purified notion of gift exchange is possibly from the vantage point of Christian theology, and finally seeks to apply this notion to the relationship between generations.
