Conceptual deficits and aging: the Category Test

Category Test performance of 41 bright aged normals was compared with the performance of 40 young normals and a group of 43 patients with suspected neurological dysfunction. The aged normals were not only as deficient as the neurologic patients but showed a similar pattern of deficits on Category subtests. The extreme difficulty experienced by aged normals and patients on Subtests III and IV was explained as a function of task complexity rather than of conceptual difficulty of conceptual principles and task complexity in a variety of impaired groups was suggested.     

THE GENERALITY OF NEGATIVE AFTEREFFECT FOLLOWING ADAPTATION TO CURVATURE

Twenty-six subjects made judgments of curvature by the method of magnitude estimation. The influence of prior adaptation to a moderate degree of curvature was assessed for test-curvatures greater and less than the adapting curvature and in the same and opposite directions. The median aftereffect was negative in all cases but not statistically significant for the most extreme difference between adapting and test curvatures. It is argued that negative aftereffect for all test-curvatures along the same stimulus-continuum is a necessary condition for postulating that these experimental effects represent a general normalizing tendency in perception.     

Body image among adolescent girls and boys: a longitudinal study

This longitudinal study of adolescent girls and boys examined the contributions of social (peer appearance context), psychological (internalized appearance ideals and appearance social comparison), and biological (body mass) factors to the development of body dissatisfaction. Students (165 girls and 139 boys) completed questionnaires when they were either in 7th grade or 10th grade and again 1 year later. The results for the boys revealed a singular pathway to body dissatisfaction through internalized commitment to muscularity ideals. The prospective analyses of change in body dissatisfaction among the girls reflected the contributions of appearance conversations with friends, appearance social comparisons, and body mass. There was no evidence of mediation among the boys and limited support for it among the girls.     

Establishing the Validity of the Spirituality in Clinical Training Scale: Measuring the Level of Integration of Spirituality and Religion in Family Therapy Training

The existing literature suggests that family therapy training programs are not adequately preparing students to address spiritual and/or religious beliefs as a resource for change in therapy. Therefore, this study sought to validate the Spirituality in Clinical Training Scale (SCTS) as a measure of the level of integration of spirituality and/or religion in family therapy training. Additionally, this study examined the latent associations among the subscales of the SCTS and measures of personal importance of spirituality, spiritual clinical competence, and spiritual self-exploration. Finally, given that the type of educational institution (i.e., religious compared to non-religious schools) may influence the extent to which spirituality is addressed in training, this study examined whether attending a religious or non-religious institution moderated the associations among the SCTS and constructs used to assess validity. A sample of 341 master’s and doctoral family therapy students completed an on-line survey for this study. The results suggest that the SCTS is a reliable and valid measure for assessing integration of spirituality into family therapy training. The establishment of this measure is important given that no previous scale measuring the integration of spirituality into therapy training exists. The results also suggest that spiritual self-exploration is associated with increased use of interventions that integrate spirituality into therapy. Implications for clinical training are discussed.     

Testing Models of Psychopathology in Preschool-aged Children Using a Structured Interview-based Assessment

A number of studies have found that broadband internalizing and externalizing factors provide a parsimonious framework for understanding the structure of psychopathology across childhood, adolescence, and adulthood. However, few of these studies have examined psychopathology in young children, and several recent studies have found support for alternative models, including a bi-factor model with common and specific factors. The present study used parents’ (typically mothers’) reports on a diagnostic interview in a community sample of 3-year old children (n?=?541; 53.9 % male) to compare the internalizing-externalizing latent factor model with a bi-factor model. The bi-factor model provided a better fit to the data. To test the concurrent validity of this solution, we examined associations between this model and paternal reports and laboratory observations of child temperament. The internalizing factor was associated with low levels of surgency and high levels of fear; the externalizing factor was associated with high levels of surgency and disinhibition and low levels of effortful control; and the common factor was associated with high levels of surgency and negative affect and low levels of effortful control. These results suggest that psychopathology in preschool-aged children may be explained by a single, common factor influencing nearly all disorders and unique internalizing and externalizing factors. These findings indicate that shared variance across internalizing and externalizing domains is substantial and are consistent with recent suggestions that emotion regulation difficulties may be a common vulnerability for a wide array of psychopathology.     

Dynamic Inconsistency and Performable Plans

An agent may abandon an initiated action plan, although he doesnot acquire new information or encounter unforeseen obstacles.Such dynamic inconsistency can be to the agent';s guaranteeddisadvantage, and there is a debate on how it should rationallybe avoided. The main contenders are the sophisticated andthe resolute approaches. I argue that this debate is misconceived,since both approaches rely on false assumptions about theperformability of action plans. The debate can be reformulated,so as to avoid these mistaken assumptions. I try to show that sucha reformulation must rely on certain implausible claims.     

Implicit temporal tuning of working memory strategy during cognitive skill acquisition

Complex cognitive tasks such as multiple-step arithmetic entail strategies for coordinating mental processes such as calculation with processes for managing working memory (WM). Such strategies must be sensitive to factors such as the time needed for calculation. In 2 experiments we tested whether people can learn the timing constraints on WM demands when those constraints are implicitly imposed. We varied the retention period for intermediate results using the well-known digit size effect: The larger the operands, the longer it takes to perform addition. During learning participants practiced multiple-step arithmetic routines combined with large or small digits. At transfer, they performed both practiced and novel combinations. Practice performance was affected by digit size and WM demands. However, the transfer performance was not fully explained by the digit size effect or the practice effect. We argue that participants acquired temporal tuning of the WM strategy to the implicit retention interval imposed by the digit size and kept using the tuning mode to unpracticed data set.
