Working memory training improves reading processes in typically developing children

The goal of this study was to investigate whether a brief cognitive training intervention results in a specific performance increase in the trained task, and whether there are transfer effects to other nontrained measures. A computerized, adaptive working memory intervention was conducted with 9- to 11-year-old typically developing children. The children considerably improved their performance in the trained working memory task. Additionally, compared to a matched control group, the experimental group significantly enhanced their reading performance after training, providing further evidence for shared processes between working memory and reading.     

Developmental change in the neuropsychological functioning of very low birth weight infants

Research on very low birth weight (VLBW) infants has not carefully evaluated developmental patterns of neurological and neuropsychological functioning across time. This study reports on a broad range of developmental outcomes for VLBW infants of low (LR, n = 116) and high (HR, n = 84) medical risk compared to full term infants (FT, n = 120) across 6, 12, and 24 months of age. While low risk infants showed initial delays in most areas, faster rates of change in motor and neurological development resulted in catch-up by 2 years of age as compared to the FT infants. The lack of acceleration in development of mental skills demonstrates a persistent lag in this area. In contrast, HR infants showed initial delays in all areas as compared to both LR and FT infants with slower rates of change in mental and expressive language skills. Although faster rates of change were evident for HR infants in motor, neurological, and receptive language skills, scores in these areas remain lower than those for the LR and FT infants. The absence of accelerated rates of development for certain VLBW infants has implications for prognosis and patient access to early intervention services.     

Measurement of the size effect in the yield strength of nickel foils

There is a growing consensus that materials become stronger in small volumes and in the presence of large strain gradients. It has not been clear whether this is due to increased resistance to the motion of dislocations, fewer dislocations, or increased difficulty of multiplying dislocations in these situations. A classic experiment by Stölken and Evans (J.S. Stölken and A.G. Evans, Acta metall. 46 5109 (1998)) showed that thin nickel foils under bending display increased strengthening at large plastic strain values and, correspondingly, large plastic strain gradients. We have adapted their technique to small strains, and report preliminary data for the stress–strain curves of thin nickel foils through the elastic–plastic transition. These data show unambiguously that the yield strength is greater in the thinner foils. The strengthening is additive to the Hall–Petch effect, and is consistent with a size effect at the onset of plastic deformation.     

Images: Preliminary scale construction

Abstract

In a series of papers, Bagarozzi and Giddings outlined a theoretical model of mate selection and marital interaction based upon principles of cognitive matching (Bagarozzi, 1982, 1986; Bagarozzi&Giddings, 1983, 1984). Briefly, this theory postulates that individuals seek out, develop intimate relationships with, and eventually marry persons whom they perceive to: (a) possess specific personality traits, qualities and characteristics; (b) share similar values, beliefs, and ideas concerning husband/wife roles; and (c) subscribe to a similar set of rules and assumptions governing interpersonal power, distributive justice, and the exchange of value messages between intimates. Essentially, one marries a person whom he/she perceives to fit an internal cognitive model or schema of an “ideal spouse.” The term “ideal” does not denote perfection. It merely represents an enduring image that becomes a standard against which all prospective mates are judged and evaluated. This cognitive matching takes place at both conscious and unconscious levels of awareness.     

Longitudinal Test of Forgiveness and Perceived Forgiveness as Mediators between Religiosity and Marital Satisfaction in Long-Term Marital Relationships

Abstract

Substantial research has found relations between religiosity and martial satisfaction. More longitudinal studies are needed to understand the inner-workings of this relationship. Over a four-year period, dyadic data from 331 married couples was used to test the longitudinal mediating effects of spousal forgiveness and partners’ perceptions of spousal forgiveness between religiosity and marital satisfaction. Husbands’ religiosity was associated with increases in wives’ marital satisfaction but the measures of forgiveness were not significant mediators in this relationship. Wives’ religiosity was predictive of lower levels of wives’ perceptions of spousal forgiveness, which led to decreases in both wives’ and husbands’ marital satisfaction.     

Reduced specificity of autobiographical memory as a moderator of the relationship between daily hassles and depression

Autobiographical memory biases are potential cognitive vulnerability factors for depression, with recent research highlighting the potential importance of accompanying high levels of life stress. Using a prospective design, the current study examined the role of autobiographical memory performance, both reduced specificity and propensity towards categoric memories, as moderators of the relationship between life stress and depression in a non-clinical college sample. Findings suggest that an increased propensity towards categoric recall emerged as a vulnerability factor for future depressive symptoms, with this vulnerability not being dependent upon the presence of high levels of life stress. In contrast, while reduced autobiographical memory specificity did not emerge as a vulnerability factor alone, it did emerge as a moderator of the relationship between chronic daily hassles and depression. These findings highlight the potential importance of both propensity towards categoric recall and reduced specificity of autobiographical memory as vulnerability factors for the experience of future depressive symptoms.

There is more than obeying display rules: Service employees’ motives for emotion regulation in customer interactions

Although research has focused on how service employees regulate their emotions, few studies have explored why they do so. In this article, we first described which kinds of motives for emotion regulation exist in customer interactions. Second, we investigated how the motives are related to four emotion regulation strategies. The application of an explorative approach resulted in a list of 10 motives, which could be classified into the three motive categories: pleasure, prevention, and instrumental. Hierarchical linear modelling of 421 reported service interactions from a diary study revealed that the motive categories were differently related to the emotion regulation strategies. Motives of the instrumental category were only significantly positively related to surface acting. Motives of the pleasure category were positively related to deep acting and automatic regulation as well as negatively related to surface acting and emotional deviance. Motives of the prevention category were positively related to deep acting, surface acting, and emotional deviance as well as negatively related to automatic regulation. These results can be used by organizations not only to enhance the motivation of employees towards emotion regulation, but also towards more authentic emotional expressions.     

How cognitive is psychomotor slowing in depression? evidence from a meta-analysis

Abstract

The current meta-analysis explores the hypothesis that many of the apparently specific deficits that depressed subjects show on speeded cognitive tasks are actually the result of general (i.e., task-independent) slowing. Results of three analyses provided strong support for this hypothesis. the reaction times (RTs) of the depressed groups were consistently slower than those of the control groups. Moreover, the degree of cognitive slowing was approximately the same regardless of the task or condition. Regression analyses revealed a proportional relation between the RTs of the two depressed and control groups, suggesting that depression slows sensory/motor and cognitive processes to approximately the same degree. the regression-based approach used in the present analyses has implications for the study of other neurological disorders and also may have important applications in the assessment of both general and specific cognitive deficits in individual patients.
