Application of Cognitive Load Theory to Develop a Measure of Team Cognitive Efficiency

Improving human systems integration through technologically advanced training and performance aids has become increasingly important to military transformation. Measures of improved cognitive and coordination processes arising from the employment of transformational tools are necessary to guide the refinement and future development of such technologies. In this article, we describe a cognitive load theory approach to developing a combinatory measure of individual workload and team performance following an experimental intervention involving training and a decision support system. We discuss how indicators of what we term team cognitive efficiency can improve assessing the effectiveness of transformational processes and technologies.     

Clinical Commentary

This paper describes a lengthy period of psychotherapy with a child. This treatment began only after a prolonged contact with other child and adolescent mental health services during which the child's difficulties, which had initially seemed to be ordinary behavioural problems, had proved puzzlingly intractable to a variety of interventions. Subsequent psychotherapy revealed a profound disorder of development which lay bath the Surface presentation. In a climate where Asperger's syndrome is often felt to be untreatable, this paper argues that some children, at least, can benefit from psychotherapy and can be helped towards real mental growth. Asperger's syndrome in children bears some striking similarities to narcissistic personality disorder as described in the adult psychoanalytic literature and this paper discusses some of the theoretical and clinical implications of the innate origins of Asperger's syndrome.     

The neural correlates of statistical learning in a word segmentation task: An fMRI study

Functional magnetic resonance imaging (fMRI) was used to assess neural activation as participants learned to segment continuous streams of speech containing syllable sequences varying in their transitional probabilities. Speech streams were presented in four runs, each followed by a behavioral test to measure the extent of learning over time. Behavioral performance indicated that participants could discriminate statistically coherent sequences (words) from less coherent sequences (partwords). Individual rates of learning, defined as the difference in ratings for words and partwords, were used as predictors of neural activation to ask which brain areas showed activity associated with these measures. Results showed significant activity in the pars opercularis and pars triangularis regions of the left inferior frontal gyrus (LIFG). The relationship between these findings and prior work on the neural basis of statistical learning is discussed, and parallels to the frontal/subcortical network involved in other forms of implicit sequence learning are considered.     

Behavior Rating Inventory of Executive Function – Preschool Version (BRIEF-P): Test Review and Clinical Guidelines for Use

The Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) is a standardized questionnaire that measures executive functioning in preschoolers. This test review provides an overview of the BRIEF-P, including scale structure, administration, norms, score interpretation, current reliability and validity evidence, and provides general guidelines for clinical use.     

Suicide ideation and depression in university students in Botswana

The study aimed at exploring suicide ideation and its relationship to depression in university students in Botswana. Data were collected from 122 undergraduate students (68.9% females, 31.1% males) with a mean age of 20.02 years. Depressive symptoms were measured with an adapted version of Beck's Depression Inventory-II. In total, 47.5% of the respondents reported suicide ideation, 28.7% reported previous suicide attempts, and the mean depression score was 19.14. Suicide ideation correlated strongly with total depression scores. The level of depression severity was linearly related to suicide ideation but 14.3% of respondents who scored at the level of minimal depression and 53.8% of those who scored at the level of mild depression had also contemplated suicide. The level of education of respondents’ mothers had an inverse relationship with suicide ideation and with depression in that those whose mothers had a tertiary level education were less likely to engage in suicide ideation and had significantly lower depression scores. The results are discussed from within the specific social ecological context of Botswana.     

Brief treatment with alprazolam and behavioral guidance in panic disorder

Abstract

Thirty-two patients with panic disorder, with or without agoraphobic limitations, were treated with alprazolam (mean dose 3.5 mg/d) plus brief behavioral guidance in an open study during eight weeks. The sample had a notorious severity in the frequency of panics and phobic avoidance but was only mildly depressed. Before starting treatment the presence of demoralized mood and extensive avoidance were significant indicators of clinical severity, whereas the presence of dizziness as a relevant somatic complaint was not related to higher severity. After eight weeks of treatment a clinical improvement equal to or exceeding 80% of change was obtained in all cases (29) who completed treatment. Ninety-two percent of the patients were panic free at the end of treatment. There were significant reductions in all the scales with comparable declines in the subgroups formed according to the presence or absence of agoraphobic avoidance and demoralization. The data suggested that moderate doses of alprazolam could be a quick and effective treatment for panic-agoraphobic patients in the short term. The behavioral guidance probably helped in reducing agoraphobic avoidance and in obtaining global good effectiveness although this awaits controlled tests. Finally, the similarity in the response to treatment regardless of the presence of extensive avoidance or demoralized mood argues in favor of not considering the different variants of panic-agoraphobic syndrome differently, at least in samples with similar severity to the present one.
