Adaptive training leads to sustained enhancement of poor working memory in children

Working memory plays a crucial role in supporting learning, with poor progress in reading and mathematics characterizing children with low memory skills. This study investigated whether these problems can be overcome by a training program designed to boost working memory. Children with low working memory skills were assessed on measures of working memory, IQ and academic attainment before and after training on either adaptive or non‐adaptive versions of the program. Adaptive training that taxed working memory to its limits was associated with substantial and sustained gains in working memory, with age‐appropriate levels achieved by the majority of children. Mathematical ability also improved significantly 6 months following adaptive training. These findings indicate that common impairments in working memory and associated learning difficulties may be overcome with this behavioral treatment.     

Assessment of stress-buffering effects of social networks on psychological symptoms in an inner-city elderly population

Social network researchers have been divided into two camps: those who propose that social networks have a direct effect on subsequent psychological symptoms and those who posit a stress-buffering effect as well. Previous research has been limited by rudimentary measures of social interaction and the absence of longitudinal data as well as by different approaches to the assessment of possible buffering effects. In the present study, using 19 social network variables, the authors followed 133 elderly residents of mid-Manhattan SRO hotels for 1 year. Three different methods of determining buffering effects were examined: Dividing the sample into high- and low-stress groups and contrasting differences in percentage variance accounted for by social networks between the two groups; Examining the group as a whole to assess if any Network Variable X Stress interactional terms are significant; Examining the group as a whole to assess whether there is a reduction in the beta value of stress with respect to psychological symptoms when network variables are added to the analysis. Method 1 indicated a direct network effect, but none of the methods indicated a buffering effect. Of clinical relevance was the nonlinearity of the network effects, that is, depending upon a person's stressor level, different network dimensions must be emphasized and strengthened.     

The timing of psychosocial transitions and changes in women's lives: an examination of women aged 45 to 60

Sixty-four middle-class women from four cohorts aged 45, 50, 55, and 60 participated in a retrospective interview concerning psychosocial changes in their adult lives. Their responses provided self-report data relating to specific psychosocial changes, and judges who read the interview protocols provided independent ratings of major psychosocial transitions. The results indicated that major psychosocial transitions were more likely to be associated with phases of the family cycle than with chronological age; within the family cycle, transitions were more likely to occur during the preschool (28% of the women), launching (42% of the women), and postparental (33% of the women) phases than during the no children, school-age, or adolescent phases; transitions associated with the preschool and launching phases were characterized by dissatisfaction, personal disruption, marital unhappiness, and decreased personal development, whereas transitions associated with the postparental phase were characterized by personal mellowing and improved marital relations; and finally, numerous self-reported psychosocial changes were associated with family cycle phase, and a small number of changes was associated with chronological age.     

RELIGION IN AN AGE OF SCIENCE; METAPHYSICS IN AN ERA OF HISTORY

Abstract. Ian Barbour's Religion in an Age of Science is a welcome systematic, theoretical overview of the relations between science and religion, culminating his long career with a balanced and insightful appraisal. The hallmarks of his synthesis are critical realism, holism, and process thought. Barbour makes even more investment in process philosophy and theology than in his previous works. This invites further inquiry about the adequacy of a highly general process metaphysics in dealing with our particular, deeply historical world; also further inquiry about the adequacy of its panexperientialism and incrementalism.     

Click location and syntactic structure

Four experiments are reported in which Ss had to judge the location of clicks superimposed on recorded sentences. The first experiment showed that the accuracy of locating the clicks was a function of the position of the click in the constituent structure, the greatest accuracy being for clicks at major clause boundaries. The second experiment showed that this effect was independent of migration, i.e., the tendency for judgments to be displaced towards the major clause break. In the third experiment, it was shown that the requirement that S reproduce the sentence did not influence the response distribution. Finally, in the fourth experiment, a small but significant trend for location accuracy to decrease with decreasing separation of the click from the major break was found. However, this trend was much smaller than the differences in accuracy for various positions in the constituent structure. It was concluded that click location accuracy can be used as an index of perceptual processing load during recognition of individual sentences.     

Warm and cool thresholds as a function of rate of stimulus temperature change

Ss lifted three weights in sequence with instructions to judge the average heaviness of the weights. In agreement with previous work, a recency effect was obtained, with the later weights having more influence on the judgment. In contrast to previous work, a discrepancy was found from predictions based on the hypothesis that the judgment was an average of the felt heavinesses of the weights. The discrepancy had the appearance of a response end-effect, and was eliminable by a scaling procedure based on functional measurement.
