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.     

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.     

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.     

A comparison of two college classroom testing procedures: required remediation versus no remediation

Forty one subjects from a 10-week introductory course in Educational Psychology were randomly divided into two experimental groups. All students took weekly quizzes over content material. Members of one group received little or no academic credit if they performed at less than 90% on a weekly quiz, but could earn additional credit by taking a weekly remedial quiz. Members of the second group also took the initial weekly quizzes, but retained their raw scores and were not permitted to take the weekly remedial quizzes. Performance on a 100-item multiple-choice comprehensive final revealed a statistically significant and educationally important difference between the two groups, the required-remediation group scoring an average of one-half letter grade higher.     

Using Information from an Early Intervention Program to Enhance Literacy Goals on the Individualized Education Program (IEP)

The Individuals with Disabilities Education Act requires that an Individualized Education Program (IEP) be developed for each child that receives special education services. To develop the most effective IEP, information is gathered from everyone who has worked with the child. In many schools the child receives early intervention services prior to referral to special education. One early intervention program that is utilized for first grade children falling behind in reading and writing is Reading Recovery®. The detailed information gathered as part of this program provides invaluable information that may facilitate development of appropriate literacy goals. This article discusses the information that is collected in the Reading Recovery program and provides an example of how this information can be utilized to support the development of IEP literacy goals.     

Input restriction and immediate memory decay in normal and subnormal children

Twelve imbeciles and 12 normals, matched for their digit memory span, were presented with three digit numbers successively and simultaneously. Seven speeds of presentation were used. Each simultaneous speed of presentation had a corresponding successive speed. Subjects were required to recall digits on the conclusion of presentation of each number. Each performance was scored as the number of errors for each digit. With simultaneous presentations the difference between the groups was significant only at fast presentation speed, where the normals were significantly better than the imbeciles. Imbeciles improved at slow speeds and became as good as normals. In the case of successive presentations differences between groups occur only in relation to the second digit, which the normals remember better than the subnormals. Both groups remember the first digit worst as rates of presentation become progressively slower. Results are explained in terms of input restriction and of memory trace decay.
