Psychometric properties of the Coping Strategy Indicator (CSI) in a study of coping behaviour amongst malawian students

Abstract

The Coping Strategy Indicator (CSI; Amirkhan 1990) is an inductively derived measure of responses to adverse circumstances. Although seeking to isolate “a few fundamental strategies with wide applicability” (Amirkhan 1990). the initial validation studies were all based on Californian populations. The present study repork findings from completion of the CSI by 415 Malawian students as part of their enrolment health check up. Factor analysis (principal components analysis with varimax rotation) identified three factors with very similar structure and loadings to those identified by Amirkhan, namely, Support Seeking, Problem Solving and Avoidance. As with the initial validation study, there was some evidence of withdrawal and distraction forming identifiable sub-components of Avoidance. The CSI does appear to provide a measure of core coping strategies which is robust across cultural settings, the theoretical implications of which are considered. The influence of factors such as age and gender on CSI scores is discussed     

Objective assessment of the functional role of spike train correlations using information measures

The functional role of correlations between neuronal spike trains remains strongly debated. This debate partly stems from the lack of a standardized analysis technique capable of accurately quantifying the role of correlations in stimulus encoding. We believe that information theoretic measures may represent an objective method for analysing the functional role of neuronal correlations. Here we show that information analysis of pairs of spike trains allows the information content present in the firing rate to be disambiguated from any extra information that may be present in the temporal relationships of the two spike trains. We validate and illustrate the method by applying it to simulated data with variable degrees of known synchrony, and by applying it to recordings from pairs of sites in the primary visual cortex of anaesthetized cats. We discuss the importance of information theoretic analysis in elucidating the neuronal mechanisms underlying object identification.     

Practice Effects on Motor Control in Healthy Seniors and Patients with Mild Cognitive Impairment and Alzheimer's Disease

ABSTRACT

This research was designed to test the hypothesis that motor practice can enhance the capabilities of motor control in healthy controls (NC) and patients with a diagnosis of probable Alzheimer's disease (AD) and mild cognitive impairment (MCI), and consequently results in better motor performance. Approximately half of the subjects in the NC (n = 31), AD (n = 28), and MCI (n = 29) either received or did not receive practice on a task of fast and accurate arm movement with a digitizer. Changes in movement time (MT), movement smoothness (jerk), and percentage of primary submovement (PPS) were recorded and compared among the three groups across six blocks of trials (baseline and five training sessions). For all subjects, practice improved motor functions as reflected by faster and smoother motor execution, as well as a greater proportion of programming control. Compared to unaffected matched controls, AD and MCI subjects exhibited a greater reduction in movement jerk due to practice. Movement time and PPS data revealed that motor practice appeared to reduce the use of “on-line” correction adopted by the AD or MCI patients while performing the aiming movements. Evidently, their arm movements were quicker, smoother, and temporally more consistent than their untrained peers. The findings of this study shed light on how MCI and AD may affect motor control mechanisms, and suggest possible therapeutic interventions aimed at improving motor functioning in these impaired individuals.     

Dependence on Visual Feedback During Motor Skill Learning in Alzheimer's Disease

Three experiments examined the role of visual feedback on the performance of a fine motor task, namely the rotary pursuit, in patients with Alzheimer's disease (AD) and healthy older adults. After extensive practice tracking a fully visible target, participants in Experiments 1 and 2 were tested under restricted vision (RV) conditions. In both experiments, the two groups showed a drop in performance when vision was restricted, with AD patients showing a significantly larger decline. Tracking improved significantly in normal controls, but not AD patients across the RV trials after the initial drop. When difficulty of the rotary pursuit task was manipulated in Experiment 3 without restricting vision, AD patients and normal controls showed identical patterns of performance. Consequently, it could be concluded that AD patients in the first two experiments were relying more heavily on visual information for accurate performance of the tracking task than their healthy peers.     

Shepherding Group Analysis: Shepherds Past, Present and Future

The development of group analysis in Britain and Europe following the death of the founder, S. H. Foulkes is described. Group analytic training, journal and book publications are noted. Future prospects for group analysis are envisaged.     

General and Specific Cognitive and Psychomotor Abilities in Personnel Selection: The Prediction of Training and Job Performance

Use of ability tests in personnel selection is addressed beginning with methodological issues. Studies are reviewed that show that almost all the validity of cognitive tests comes from general cognitive ability, g. Psychomotor ability is reviewed and found to have both higher- and lower-order factors, contrary to long-held beliefs. It was found that the higher-order general psychomotor factor was one source of validity of psychomotor tests. Additionally, psychomotor tests were shown to contain measures of g and to increment the validity of g-based measures very little.     

Why did it happen to me? Social cognition processes in adjustment and recovery from criminal victimisation and illness

This article reviews the theoretical framework and empirical evidence for the hypothesised relationship between self-blame attributions and psychological adjustment. In doing so, an argument is presented that poses an alternative interpretation to that which is widely accepted regarding the complex relationship between blame attributions, perceived control, self-esteem, and recovery. A number of fundamental issues concerning the assumptions underlying Janoff-Bulman’s model are identified and explored. In particular, attention is given to the importance of distinguishing perceived control from likelihood of recurrence, and perceived control from outcome expectancy. Finally, the possibility that attributions may not play as fundamental a role in adjustment as first thought is considered, and future lines of enquiry are identified.
