Race-related stress, racial identity status attitudes, and emotional reactions of Black Americans

The current study explored the relationship between race-related stress, racial identity status attitudes and emotional states among 229 Black Americans. Canonical correlation analyses revealed a shared variate between emotions and racial identity status attitudes in which anger, depression confusion and tension were related positively to Conformity and inversely related to Internalization status attitudes. Implications for research are discussed.     

The therapeutic alliance in adolescent substance abuse treatment: a one-with-many analysis

Studies of the therapeutic alliance typically use a one-with-many (OWM) design in which each therapist (the one) treats multiple clients (the many). This study used Kenny, Kashy, and Cook's (2006) OWM method to examine the composition of the therapeutic alliance and to analyze the association between alliance and outcome in a sample of 398 adolescents treated for substance abuse by 14 therapists. Both the client and therapist alliance ratings yielded large relationship variances, with limited consensus among clients treated by the same therapist about the quality of the alliance. If a client reported an especially strong alliance with his or her therapist, the therapist was likely to also report an especially strong alliance with that client (dyadic reciprocity). The association between the components of the alliance and treatment outcome was complicated, with different levels of measurement and different components of the alliance (perceiver, partner, or relationship) derived from different informants (therapist or client) relating to different outcomes.     

What coping tells about personality

In this study, 123 participants (non‐psychology students) who responded to an interpersonal stress situation staged in the laboratory were judged by unacquainted observers in terms of the Big Five dimensions, intelligence and social attractiveness. Coping behaviour appeared to predict personality impressions in a way that mirrors the relations between personality and coping observed in previous research: Overall, higher levels of Extraversion (E), Agreeableness (A), Conscientiousness (C) and Openness to experience (O) (as well as intelligence and social attractiveness) were predicted by problem‐focussed behaviour and cognitive restructuring, whereas higher levels of Neuroticism (N) were predicted by withdrawal/passivity. The interpersonal impact of the particular coping reactions, as indicated by a positive personality impression, were largely inconsistent with their impact on affect following the stress induction.

Speech‐perception‐in‐noise deficits in dyslexia

Speech perception deficits in developmental dyslexia were investigated in quiet and various noise conditions. Dyslexics exhibited clear speech perception deficits in noise but not in silence. Place‐of‐articulation was more affected than voicing or manner‐of‐articulation. Speech‐perception‐in‐noise deficits persisted when performance of dyslexics was compared to that of much younger children matched on reading age, underscoring the fundamental nature of speech‐perception‐in‐noise deficits. The deficits were not due to poor spectral or temporal resolution because dyslexics exhibited normal ‘masking release’ effects (i.e. better performance in fluctuating than in stationary noise). Moreover, speech‐perception‐in‐noise predicted significant unique variance in reading even after controlling for low‐level auditory, attentional, speech output, short‐term memory and phonological awareness processes. Finally, the presence of external noise did not seem to be a necessary condition for speech perception deficits to occur because similar deficits were obtained when speech was degraded by eliminating temporal fine‐structure cues without using external noise. In conclusion, the core deficit of dyslexics seems to be a lack of speech robustness in the presence of external or internal noise.     

Overweight and cognition

There is a growing concern among health authorities that an increasing number of people in the Western world become overweight and even obese. It is well known that obesity is related to several diseases (e.g., diabetes, stroke, and high blood pressure) and that such diseases related to obesity lead to early death. It has also been discussed whether overweight and obesity in themselves or in relation to such diseases lead to cognitive decline. On the basis of data from a large, population‐based, prospective study we examined three cognitive domains: episodic memory, semantic memory, and spatial ability. Two body measures were used to define normal weight and overweight, body‐mass index and waist/hip ratio. Although these two body measures reveal quite different prevalence data of overweight, the associations between overweight and cognition are similar. For episodic memory, overweight interacts with age, but when controlling for hypertension, stroke and diabetes, this interaction disappears. For semantic memory, normal weight participants outperform overweight participants even after controlling for these diseases. For spatial ability, the well‐established advantage for men holds for young‐old and old‐old normal‐weight participants. For overweight participants, this advantage holds for middle‐age participants only. We conclude that there is a weight‐cognition relationship even after controlling for obesity‐related diseases. The results are discussed in terms of possible biological mechanisms.     

Executive disorders and perceived socio‐emotional changes after traumatic brain injury

Although socio‐emotional changes are very frequently encountered after traumatic brain injury (TBI), the psychological mechanisms underlying these disorders are still poorly understood. This study aimed to explore the relationships between dysexecutive syndrome (assessed with the Behavioural Assessment of the Dysexecutive Syndrome [BADS]) and socio‐emotional changes assessed by the Iowa scales of personality change (ISPC) in patients with TBI. The BADS was thus administered to 25 patients with TBI and to 25 healthy controls. Simultaneously, a close relative of each patient was given the ISPC in order to assess socio‐emotional changes. Results indicated that patients displayed significantly lower executive performances than controls and experimented significant socio‐emotional changes. The Modified Six Elements Test was the only subtask of the BADS to be significantly related to behavioural changes, and more specifically to externalizing disorders. It is concluded that executive functions, and especially multitasking, encompass processes whereby one can consciously control one's emotional reactions and behaviours.     

Sunk-cost effects on purely behavioral investments

Although the sunk-cost effect is a well-documented psychological phenomenon in monetary investments, existing literature investigating behavioral investments (e.g., time, effort) has not replicated this effect except when such investments relate to monetary values. The current explanation for this discrepancy proposes that purely behavioral sunk-cost effects are unlikely to be observed because they are difficult to book, track, and balance in a mental account. Conversely, we argue that, through an effort-justification mechanism, people account for the amount of behavioral resources invested when selecting an alternative, in which case they may fall prey to purely behavioral sunk-cost effects. The results of two experiments support this prediction. Because many decisions involve behavioral investments, behavioral sunk-cost effects should be pervasive psychological phenomena.     

Individual difference influences on self-focused and other-focused counterproductive student behaviors

This paper extends previous research on counterproductive student behaviors by presenting an individual difference model of counterproductive student behaviors (CSBs) that includes four sets of antecedent variables: internal control variables; propensity variables; achievement striving; and severity perceptions of CSBs. Data from 276 undergraduate students shows that CSBs exhibit a two-factor solution (self-focused and other-focused CSBs), and that each of the four sets of antecedent variables explain unique variance in either self-focused CSBs or other-focused CSBs; with the influence of achievement striving being restricted to behaviors that harm the academic performance of students. The results are discussed in terms of their relationship with previous research on counterproductive behaviors and their implications for understanding of the broad domain of college student performance.
