A linear growth curve analysis of inpatient treatment response by conduct‐disordered,ADHD, and comorbid preadolescents

Conduct disorder (CD) comorbid with attention deficit hyperactivity disorder (ADHD) is widely reputed to be treatment refractory, particularly when accompanied by aggression and early‐onset symptoms. Few studies, however, have assessed inpatient treatment response among early onset CD/ADHD children in detail. In the present investigation, behavioral and rating scale data were compared among CD (n=13), ADHD (n=20), and CD/ADHD (n=45) preadolescents during one‐month of multimodal inpatient treatment that included methylphenidate administration. As expected, linear growth curve analyses revealed that CD/ADHD children were the most symptomatic of the three groups. However, all groups benefited from hospitalization, with few differences in treatment responsiveness observed. Analyses of residualized symptoms suggested that methylphenidate administration was effective in curbing impulsive but not aggressive behaviors. Aggr.

The simplicity principle in human concept learning

How do we learn concepts and categories from examples? Part of the answer might be that we induce the simplest category consistent with a given set of example objects. This seemingly obvious idea, akin to simplicity principles in many fields, plays surprisingly little role in contemporary theories of concept learning, which are mostly based on the storage of exemplars, and avoid summarization or overt abstraction of any kind. This article reviews some evidence that complexity minimization does indeed play a central role in human concept learning. The chief finding is that subjects' ability to learn concepts depends heavily on the concepts' intrinsic complexity; more complex concepts are more difficult to learn. This pervasive effect suggests, contrary to exemplar theories, that concept learning critically involves the extraction of a simplified or abstracted generalization from examples.     

Self-Efficacy for Enhancing Students’ Career and College Readiness: A Survey of Professional School Counselors

Grounded in Bandura’s (1997) self-efficacy theory and Savickas’s (2011) career construction theory, this study examined school counselors’ beliefs about whether they can perform specific tasks related to supporting students’ career and college readiness. A national sample of school counselors (N = 2,047) completed the School Counselor Self-Efficacy for Enhancing Student Career and College Readiness Scale (Baker, Parikh-Foxx, & Martinez, 2017). Findings from a survey research design indicated that the extent of related training and the challenges associated with implementation of career service delivery were of concern to participants. Recommendations for training, practice, and further research are presented.
