Like and cross modality responses in normal and subnormal children

Experiments which investigated response behaviour in imbeciles and normals, in a conflict situation between a general verbal instruction and direct stimuli, were carried out. It was found that combined verbal-motor responses did not give better results than either verbal or motor responses alone. Results in accordance with the general instruction were significantly better if the subnormal children responded in a different modality from the one in which the signals were given. While normals and imbeciles differed markedly in their ability to perform the tasks in like-modality trials, this difference was less apparent in cross modality responses.     

Modification of social withdrawal through symbolic modeling

The present experiment was designed to test the efficacy of symbolic modeling as a treatment to enhance social behavior in preschool isolates. Nursery school children who displayed marked social withdrawal were assigned to one of two conditions. One group observed a film depicting increasingly more active social interactions between children with positive consequences ensuing in each scene, while a narrative soundtrack emphasized the appropriate behavior of the models. A control group observed a film that contained no social interaction. Control children displayed no change in withdrawal behavior, whereas those who had the benefit of symbolic modeling increased their level of social interaction to that of non-isolate nursery school children.     

Presence and television.

Film and a number of emerging entertainment technologies offer media consumers an illusion of nonmediation known as presence. To investigate the possibility that television can evoke presence, 65 undergraduate students were shown brief examples of rapid point‐of‐view movement from commercially available videotapes on a television with either a small screen (12 inches [30.5 cm], measured diagonally) or a large screen (46 inches [116.8 cm]). Participants' responses were measured via a questionnaire and a computer‐based recording of arousal (electrodermal activity). Viewers of both televisions reported an enjoyable sense of physical movement, excitement, involvement, and a sense of participation. Furthermore, as predicted, participants who watched the large screen television thought the movement in the scenes was faster, experienced a greater sense of physical movement, enjoyed the movement to a greater extent, found the viewing experience more exciting, and were more physiologically aroused. Practical and theoretical implications are discussed.     

Negotiators' bargaining histories and their effects on future negotiation performance

In 2 studies the authors show that the quality of deals negotiators reach are significantly influenced by their previous bargaining experiences. As predicted, negotiators who reached an impasse on a prior negotiation were more likely either to impasse in their next negotiation or to reach deals of low joint value compared to those who had reached an initial agreement. Notably, the impact of past performance on subsequent deals was just as strong for negotiators who changed partners on the 2nd occasion. Results highlight the role of bargaining histories as significant predictors of negotiation behavior. Moreover, they suggest that, at least in some cases, negotiations should be conceptualized as interrelated exchanges rather than separable incidents.     

Forms, uses and functions of children's favourite objects

In this study, the notion of a favourite object is used as a heuristic concept for things that children are occupied with and absorbed by. According to earlier studies, favourite objects can be grouped into four categories: forerunners of transitional objects, primary and secondary transitional objects, and favourite toys. This initial classification was compared to results of cluster analyses of characteristics of favourite objects among 32 preschool and 30 primary school children, corroborating the initial classification and specifying the typology. The distribution of types of objects was different for the two groups of children, but was not dependent on age within groups or, for the preschool children, on mental development. These results indicate that changes of favourite objects with mental maturation are slow.
The softness of the material of primary and secondary transitional objects and the preference for objects that could be kept close to the body suggest that the comforting character of these favourite objects has its root in the child's self-soothing actions with the object.     

Construction et Validation de l'Échelle de Motivation pour les Personnes Âgées (EMPA)

Le but de cet article consiste à présenter les résultats de quatre études ayant pour objectif de construire et valider un nouvel instrument mesurant la motivation des personnes âgées vis-à-vis les activités importantes de leur vie, soit l'échelle de Motivation pour les Personnes Âgées (EMPA). L'EMPA est formée de quatre sous-échelles mesurant la motivation intrinsèque, la motivation extrinsèque autodéterminée, la motivation extrinsèque non-autodéterminée et l'amotivation, et ce dans six domaines de vie jugés importants par les personnes âgées: la santé, la religion, les informations, les loisirs, les relations interpersonnelles et les besoins biologiques. Dans l'ensemble, les résultats révèlent que l'EMPA possède une cohérence interne élevée ainsi qu'une stabilité temporelle satisfaisante. En plus, la validité de l'EMPA a été soutenue par: (1) l'existence d'un pattern de corrélations de type simplex entre les quatre sous-échelles, (2) des corrélations significatives entre les réponses des personnes âgées et l'évaluation des intervieweures quant à la motivation des personnes âgées et enfin (3) par des analyses de tests-t qui révèlent, en accord avec la théorie de Deci et Ryan (1985), que les personnes âgées qui se perçoivent très autodéterminées dans leur centre d'accueil ont des pointages plus élevés sur les sous-échelles de motivation intrinsèque et de motivation extrinsèque autodéterminée, mais des pointages plus faibles sur les sous-échelles de motivation extrinsèque non-autodéterminée et d'amotivation, que celles qui se perçoivent comme étant peu autodéterminées. Les présents résultats démontrent donc, du moins dans un premier temps, la validité et la fidélité de l'EMPA. Celle-ci semble donc prěte à ětre utilisée en recherche auprès des personnes âgées. A cet effet, on suggère un certain nombre de pistes pour les recherches futures quant à son utilisation dans ce secteur.     

Physical activity does not provoke panic attacks in patients with panic disorder: A review of the evidence

Abstract

This paper summarizes the results of published studies in which physical activity has been performed by patients with panic disorder. Several case studies of apparent exercise-induced panic attacks were found. However, in field studies that involved ambulatory monitoring of panic disorder patients only 1 of 91 panic attacks that were monitored actually occurred while the test subject was engaged in moderately intense physical activity. Moreover, only five panic attacks occurred in association with 444 exercise bouts performed by 420 panic disorder patients in laboratory settings despite the fact that exercise induces somatic signs and symptoms of anxiety. Thus, the weight of the published evidence shows that acute physical activity does not provoke panic attacks in panic disorder patients.
