Perceptual linkage of multiple objects rotating in depth

When multiple objects rotate in depth, they are frequently perceived to rotate in the same direction even when perspective information signals counterrotation. Three experiments are reported on this tendency to recover the rotation directions of multiple objects in a nonindependent fashion (termed rotational linkage). Rotational linkage was strongly affected by slant in depth of the objects, image perspective, and relative starting phase of the objects. Linkage was found not to vary as a function of the relative rotation speed of the objects or the relative alignment of their rotation axes. Rotational linkage is interpreted as a tendency of the visual system to assign signed depths to objects based on a communality of image point direction.     

Changes in the level and quality of object relations in psychoanalysis: followup of a longitudinal, prospective study

As part of a prospective, longitudinal study of suitability for and outcome of psychoanalysis, 22 patients were evaluated for changes in the level and quality of their object relations. These patients had been accepted for supervised analysis with candidates in training by senior analysts who had diagnosed them as neurotic. The majority of these patients reported difficulties in relationships as at least one of their reasons for originally seeking psychoanalytic treatment. Prior to beginning analysis, each patient was given a battery of psychological tests. One year after the termination of analysis, the test battery was readministered and a followup interview was conducted separately with each patient and analyst. Ratings of change based on patient and analyst interviews and comparisons of psychological tests before and after treatment all showed statistically significant improvement in the level and quality of object relations for this patient group. The results of this study support what is often observed in clinical practice, that psychoanalysis has a positive effect on the level and quality of a patient's object relations.     

Why do people need self-esteem? Converging evidence that self-esteem serves an anxiety-buffering function.

Three studies were conducted to assess the proposition that self-esteem serves an anxiety-buffering function. In Study 1, it was hypothesized that raising self-esteem would reduce anxiety in response to vivid images of death. In support of this hypothesis, Ss who received positive personality feedback reported less anxiety in response to a video about death than did neutral feedback Ss. In Studies 2 and 3, it was hypothesized that increasing self-esteem would reduce anxiety among individuals anticipating painful shock. Consistent with this hypothesis, both success and positive personality feedback reduced Ss' physiological arousal in response to subsequent threat of shock. Thus, converging evidence of an anxiety-buffering function of self-esteem was obtained.     

SUBLIMINAL EXPOSURE TO DEATH-RELATED STIMULI INCREASES DEFENSE OF THE CULTURAL WORLDVIEW

Abstract— Three experiments reported here provide empirical support for the hypothesis derived from terror management theory that unconscious concerns about death motivate allegiance to cultural beliefs, Study 1, contrasted exposure to a subliminal death-related stimulus, a standard mortality-salience treatment, and a neutral subliminal stimulus, and found that both the subliminal and the standard reminder of mortality led to more favorable evaluations of people who praised subjects' cultural worldview and more unfavorable evaluations of those who challenged it Study 2, replicated this finding by comparing the effects of exposure to subliminal death stimuli and subliminal pain stimuli. Study 3, contrasted subliminal death stimuli, supraliminal death stimuli, and subliminal pain stimuli and found that only subliminal death stimuli produced these effects.     

Constructivism and education: education as an interpretative transformational process

This paper provides an analysis of the ideas of John Dewey and George Herbert Mead with regards the relationship between experience, meaning, language and thinking. It discusses how experience, meaning, language and thinking are based on the creative and constructive actions of individuals. Unlike what is the case in so-called radical constructivism, it is argued that the actions of the individual should be understood in a transactional way. The paper shows the implication of a transactional constructivism for education, arguing that education is the medium in which the creative and constructive actions of individuals come together in a social environment.     

Auditory event perception: The source—perception loop for posture in human gait

There is a small but growing literature on the perception of natural acoustic events, but few attempts have been made to investigate complex sounds not systematically controlled within a laboratory setting. The present study investigates listeners’ ability to make judgments about the posture (upright—stooped) of the walker who generated acoustic stimuli contrasted on each trial. We use a comprehensive three-stage approach to event perception, in which we develop a solid understanding of the source event and its sound properties, as well as the relationships between these two event stages. Developing this understanding helps both to identify the limitations of common statistical procedures and to develop effective new procedures for investigating not only the two information stages above, but also the decision strategies employed by listeners in making source judgments from sound. The result is a comprehensive, ultimately logical, but not necessarily expected picture of both the source—sound—perception loop and the utility of alternative research tools.
