ON VOLUNTARY ACTION AND ITS HIERARCHICAL STRUCTURE1

Les AA., cherchant à découvrir quels sont les caractères de l'organisation de quelques systèmes biologiques au cours de la première enfance, montrent comment un comportement primitivement automatique et réflexe se transforme graduellement en contrôle volontaire. Sur la base d'expériences qui ont porté sur la manière dont deux activités conflictuelles, téter et regarder, s'intègrent chez le bébé de 2 à 3 mois, on peut distinguer des étapes dans le processus d'organisation : (a) d'abord, suppression de I'une ou de l'autre activité; (b) ensuite, alternance des deux sans interférence; (c), enfin maintien en place des deux à la fois : la structure des deux activités est intégrée dans un acte qui les comprend I'une et l'autre, les parties y étant cependant exécutées séparément. Dans une autre expérience, on observe que les bébés s'efforcent de voir nettement, but qui est fixé arbitrairement, en coordonnant suçage et regard, à l'aide d'une stratégie de réponses qui est hiérarchiquement organisée et adaptative. Certains épisodes du développement de la manipulation des objets avec guidage visuel, montrent comment un programme d'action peut être mis en place dès le début. La maîtrise de l'action implique un cycle de restriction brutale des formes du mouvement et de formation programmée de l'habileté dans les limites de cette restriction. On peut dire, en conclusion, qu'il y a une organisation adaptative, générique et intelligente du comportement à chaque âge. Elle est atteinte de façon inégale et imparfaite, par intermittence et incomplètement : une nouvelle analyse fonctionnelle est nécessaire.     

The effect of “irrelevant” variables on decision making: Criterion shifts in preferential choice?

In decision research, it is widely assumed that decision makers have subjective experiences which indicate definitively, albeit with random fluctuations, whether or not one alternative is preferable to another. Further, it is assumed that subjects' choices reflect this underlying preference order. It follows from this position, as a logical consequence rather than an empirical observation, that if a manipulation affects people's choices, it does so by changing the way people subjectively experience the alternatives (presumably via people's encoding or combination of attribute information). In psychophysics, an analogous theoretical position has been relinquished. Specifically, it is no longer believed that observers in a detection experiment have subjective experiences which indicate definitively, albeit with error, whether a signal has been perceived. Rather, according to signal detection theory, the observer's sensory experience can be portrayed as a quantifiable sensation that must be converted into an overt report of “signal present” or “signal absent” by comparing the sensation with a criterion. In this paper, we describe two models of preferential choice, the lexicographic criterion model and a probabilistic criterion model, that replace the notion of definitive preference with an analogue of signal detection theory. In the models, the decision maker is represented as having quantifiable inclinations, rather than definitive preferences, that must be converted into an overt choice by comparing the inclinations with a criterion. By attributing the effects of experimental manipulations to shifts in the criterion, rather than to changes in people's inclinations, the model offers a testable alternative to the proposition that altered choices imply altered preferences.     

A Cross-National Study of Nuclear Attitudes,Normative Support,and Activist Behavior: Additive and Interactive Effects1

We tested the cross-national similarity of additive and interactive variants of the Contingent Consistency Hypothesis in regard to antinuclear activist behavior. We predicted that attitudinally consistent behavior is influenced (a) more by specific than general attitudes, (b) by facilitation between normative support and personal attitudes in an interactive manner, and (c) by a fundamental or basic social-psychological process that can be demonstrated in people from different countries and cultures. These three hypotheses were tested for general (pacifist) attitudes, specific (antinuclear) attitudes, normative support, and antinuclear political activism in samples of college students from the U. S., England, and Sweden. In each sample, specific attitudes were strong, unique predictors of activist behavior (more so than general attitudes), while normative support had no additive influence on this behavior beyond that explained by attitudes for U. S. and British students. Interaction effects were found for both pacifist and nuclear attitudes in conjunction with normative support among the U. S. students, but only for pacifist attitudes in the British sample and only with antinuclear attitudes in the Swedish sample. In contrast with other studies where interaction effects were hypothesized for behaviors that were deviant or typically initiated by others, the present interactions were obtained for lawful behaviors that are often begun and/ or performed alone. With some notable variations, these results were confirmed in each sample, partially validating the cross-national generality of the interactive attitude-behavior model for activist behavior.     

CUE COMPETITION EFFECTS:

Abstract— The ability to predict future consequences on the basis of previous experience with the current yet of environmental cues is one of the most fundamental of all cognitive processes. Thix sttidv investigated how the validity of one cue influences the effectiveness of another cue for predicting a criterion. The results demonstrate a cue competition effect—increasing the validity of one cue decreased the effectiveness of another cue in a linear prediction task, even though the two cues were statistically independent.     

The repressor personality and avoidant information processing: A dichotic listening study

The present research was designed to investigate the proposition that repressors, operationally defined by the conjunction of low anxiety and high defensiveness, are particularly adept at avoiding the processing of information when motivated to do so. Four groups of participants (nondefensive-low anxious, high anxious, repressors, and defensive-high anxious) were administered a dichotic listening task involving neutral or negative affective words presented in the unattended ear. Participants shadowed the material presented to the attended ear and simultaneously responded to a probe task presented on a video monitor. Results revealed that repressors made significantly fewer shadowing errors than high anxious and defensive-high anxious participants and marginally significantly fewer shadowing errors than low anxious participants for both neutral and negative words. High anxious participants, however, were later able to recognize the negative words that had been presented to the unattended ear at well above chance levels, whereas the recognition memory of repressors for such negative unattended words was at chance levels. In addition, repressors' responses to a postexperiment questionnaire indicated a significantly greater number of distracting thoughts during the experiment relative to other participants. Repressors, it seems, are indeed skillful at avoidant information processing and this capacity may well be related to the emotional memory deficits they have displayed in previous research.     

Tarasoff v. confidentiality

The Tarasoff decision is discussed as a logical extension of evolving legal doctrine imposing a special duty on caretakers. The mental health professions are being held to a standard of negligence and perhaps even to a standard of strict liability. Tarasoff is viewed as a part of society's interest in using the information disclosed in confidential relationships as a means of social control. This in turn is seen as part of a disquieting trend to curtail First Amendment rights. The adversarial nature of the relationship between the 1974 Tarasoff decision and the constitutional rights of patients to privacy, confidentiality, and privilege is discussed. The author re-asserts: “As asepsis is to surgery, so is confidentiality to psychiatry” (Beigler, 1978, p. 255).     

Relative cues and absolute distance perception

It is possible, in theory, for the simultaneous occurrence of several different relative cues of distances to increase the veridicality of the perception of absolute distance. To test whether this actually occurs, a three-dimensional display was viewed monocularly while moving the head laterally, under conditions in which some error in perceived absolute distance was expected. The perceived absolute distance of the display was measured with the number of relative cues of distance within the display varied. No systematic reduction was found in the error in perceived absolute distance as a consequence of the variation in the number of relative cues. The study provides no evidence that the potential source of absolute distance information provided by relative cues is utilized by the visual system.     

INSTRUCTIONS,FEEDBACK, AND REINFORCEMENT IN REDUCING ACTIVITY LEVELS IN THE CLASSROOM

The biomotometer, an electronic device which simultaneously measures motor activity and provides auditory feedback, was used in combination with material reinforcers in an experiment to reduce children's activity level in a classroom setting. Subjects were nine boys and two girls, aged 9–13, from a day hospital program for emotionally disturbed children. After five baseline trials, each child had five contingent reinforcement trials in which he/she received feedback “beeps” from the biomotometer and was given toy or candy rewards after each trial in which activity fell at least 20% below mean baseline level. Then five noncontingent reinforcement trials were run in which children received rewards for wearing the apparatus without the feedback attachment. Results indicated that the intervention “package,” including instructions, feedback, and contingent reinforcement, was successful in all five trials for 8 of 11 children. Activity levels increased during the final noncontingent phase.
