Using “War Stories” to Train for Adaptive Performance: Is it Better to Learn from Error or Success?

On s’est demandé, dans cette recherche, si un séminaire exploitant les erreurs pouvait améliorer les performances. 59 pompiers expérimentés en formation sur les problèmes de commandement ont participéà cette étude. Des scènes de guerre ont été conçues à partir d’évènements réels pour illustrer des décisions hiérarchiques dont les suites furent heureuses ou malheureuses. Deux méthodes de formation ont été comparées et évaluées. Un premier groupe a été confrontéà des études de cas contenant des erreurs de management aux conséquences graves sur l’intervention contre l’incendie (formation avec erreurs) alors qu’un second groupe était soumis à la même série d’études de cas, sinon que les cas décrivaient des situations gérées correctement avec leurs conséquences (formation sans erreur). Les résultats confortent l’hypothèse qu’il vaut mieux apprendre à partir des erreurs des autres plutôt qu’à partir de leurs réussites. On analyse les leçons à en tirer pour la formation. The study examines whether error exposure training can enhance adaptive performance. Fifty‐nine experienced fire‐fighters undergoing training for incident command participated in the study. War stories were developed based on real events to illustrate successful and unsuccessful incident command decisions. Two training methodologies were compared and evaluated. One group was trained using case studies that depicted incidents containing errors of management with severe consequences in fire‐fighting outcomes (error‐story training) while a second group was exposed to the same set of case studies except that the case studies depicted the incidents being managed without errors and their consequences (errorless‐story training). The results provide some support for the hypothesis that it is better to learn from other people's errors than from their successes. Implications for training are discussed.     

Behavioral phenotype of individuals with Down syndrome

Evidence is reviewed for a developmentally-emerging behavioral phenotype in individuals with Down syndrome that includes significant delay in nonverbal cognitive development accompanied by additional, specific deficits in speech, language production, and auditory short-term memory in infancy and childhood, but fewer adaptive behavior problems than individuals with other cognitive disabilities. Evidence of dementia emerges for up to half the individuals studied after age 50. Research issues affecting control group selection in establishing phenotypic characteristics are discussed, as well as the possible genetic mechanisms underlying variation in general cognitive delay, specific language impairment, and adult dementia.

GRADSCOPE: An Analysis of the Item Structure and a Survey of Usage

Two studies of GRADSCOPE, the most widely-used system for computer-assisted careers guidance in higher education in Britain, are reported. The first is an item analysis of the GRADSCOPE questionnaire. The six-factor solution from this factor analysis suggests that, with the exception of the Artistic theme, the content domain of the GRADSCOPE questionnaire covers Holland's occupational themes, and that GRADSCOPE is primarily concerned with the motivational component rather than the performance requirements of jobs. The second study, a postal survey of careers services and careers advisers about their experiences of using the interactive version of GRADSCOPE, aimed to examine the potential of interactive systems to effect change in careers work.     

Validating Personnel Selection: A Process Model for Research and Practice

This article highlights the need for a clearer conceptual appreciation of the relationships among and between predictors and criteria, and for a better understanding of measurement issues in selection. A process model of selection is outlined that includes recent research on the changing relationships of ability to performance at different stages of skill acquisition, the interaction between type of task and validity, the role of motivational constructs in the measurement and validation process, and the reciprocally interacting influences of work experience and individual characteristics. Comment is offered on issues such as general versus specific abilities, the ‘big five’in personality, aptitude by treatment or training interactions and maximal versus typical performance. Measurement issues are discussed throughout, but particularly in relation to the assessment process.     

Changes and responsibilities: Policy challenges confronting careers guidance in New Zealand

Several policy shifts and changes to careers guidance that have occurred in New Zealand recently are examined, and the difficulties faced by counsellors in coping with the ongoing change are highlighted. These developments are discussed in the broader context of major economic changes and evolving organisational structures in New Zealand among many other countries. Lessons drawn from the New Zealand experience include the importance of evaluating services, being prepared for change, and being open to new ideas where change is inevitable.     

The Human Movement Factor (M) in the Rorschach,Motor Activity,and Behavior

The relationship between the M response and one of its basic theoretical components, overt motor activity, measured by participation in varsity level sports and related activities, was determined. 114 Ss were assigned to a participant group and 108 Ss to a non-participant group. The Group Rorschach, the Group Form of Coan’s Individual Movement Cards, and the Guilford-Zimmerman Temperament Survey were administered. The results failed to confirm Rorschach’s theory that overt motor activity inhibits kinesthetic perception. Flexor movement was significantly associated with non-participation. The participant group scored significantly higher in Factors G (General Activity), A (Ascendance), S (Sociability), and E (Emotional Stability) of the Guilford-Zimmerman Temperament Survey. Intellectual functioning appeared as the most important factor in M production.     

Integrating Individual and Organizational Perspectives for Career Development and Change

This article illustrates how traditional concepts of person-environment fit and transition can be adapted to deal with change, and highlights the advantages of an integrated organizational and individual perspective on career development. Using an adapted version of the Minnesota Theory of Work Adjustment and a “Me Incorporated” metaphor, the article illustrates the need for both the individual and an organization to consider immediate and future demand and supply factors in relation to the other. In addition to placing a change overlay on training, selection and career development, the article illustrates how recommendations for dealing with organizational change can be adapted for use by “Me Incorporated”.     

Mental illness has multiple causes: beliefs on causes of mental illness by congregants of selected neo-prophetic churches in Ghana

ABSTRACT

The present study explored perceived causes of, and preferred treatment approach for, mental illness among congregants of six Neo-prophetic churches in Accra and Kumasi through in-depth interviews. Using thematic analysis, five themes emerged from participants’ causal attributions of mental illness. These included lifestyles and environmental stressors, spiritual causes, interaction of multiple factors, trauma and biological causes. Additionally, participants discussed four main mechanisms through which stress leads to mental illness. These included persistent worrying over stressors, use of inappropriate coping strategies to cope with stress, refusal to talk about one's problems and individuals’ appraisal of stress and available coping resources. These beliefs directly determined congregants’ preferred treatment approach. Implications of the findings are discussed.     

The importance of human needs during peacetime, retrospective peacetime, and the Persian Gulf War

Study 1 investigated the importance of human needs during peacetime in 1993 using a sample of 137 full-time workers in several industries in the United States. Study 2 examined the importance of needs in 1990 (retrospective peacetime) and in 1991 (during the Persian Gulf War)(both measured during the war) using a sample of 564 college students in the United States. In both studies, two levels of needs (higher-order and lower-order needs) were identified during peacetime. Study 2 revealed that during the war, all needs were rated as more important and only one factor was identified. During peacetime, the safety of one’s own life was significantly more important than the safety of the country which was rated as the least important need. During the war, the safety of the country was as important as the safety of one’s own life. Students who had spouse, family members, and friends in the Middle East during Desert Storm differed significantly from those who did not in war-related stress and the importance of several needs.     

Episodic knowledge and implicit learning

Despite nearly 20 years of controversy, researchers are still divided over the contributions of abstract and episodic knowledge to performance on implicit learning tasks, and whether these types of knowledge exert their effects unintentionally or unconsciously. The present paper reviews the evidence taken to support the episodic account of implicit learning. Although substantial evidence suggests that episodic knowledge influences performance on implicit learning tasks, at present there are no techniques for testing whether these influences occur outside of awareness. It is argued that future research should investigate whether the retrieval of episodic knowledge in implicit learning tasks is insensitive to intentional control, rather than focus on the issue of awareness. Preliminary evidence suggesting that episodic knowledge can exert a nonintentional influence on task performance is reviewed, followed by a discussion of the status of consciousness as an explanatory construct in psychology.
