DataVision: A computer-based system for generating and reading digital information accompanying video images on videotape

An Apple IIe-based system is described that generates both machine-readable and human-readable numbers for recording with visual information on videotape. Hardware and software components of the encoding system are detailed. An automatic decoding system that reads the numbers from videotape into computer memory is also described. Current applications of the system are briefly discussed.     

Effects of amount of attention allocated to the location of visual stimulus pairs on perception of simultaneity

This study examined whether a change in the amount of attention equally allocated to two locations affects judgments of the simultaneity or successiveness of stimuli presented at those locations. Observers were cued to expect two brief flashes either to the left and right of fixation or above and below fixation. Stimulus onset asynchrony was randomly varied. On a small proportion of trials, the stimuli appeared at the unexpected locations. Observers were more likely to report the stimuli as simultaneous when they appeared in the unexpected locations. A model proposed to account for the data assumes that a brief stimulus event is represented by a probability distribution reflecting the uncertainty in determining the time of the event’s occurrence, and two events are judged to be simultaneous if they are perceived to fall within some critical temporal interval, c, which is a function of the amount of attention allocated to the task.     

HOMO RELIGIOSUS AND ITS BRAIN: REALITY, IMAGINATION, AND THE FUTURE OF NATURE

Abstract. “Daddy, is God real or is he a part of people's imagination?” The brain constructs reality by bottom-up, genetically programmed mechanisms. Nature selected the human holistic, symbolically thinking, aesthetic brain using a mechanism of brain-language coevolution. Our religious nature and moral capabilities are rooted in this brain, and in the real images it constructs.     

Self-monitoring in communicative interactions: Social cognitive consequences of goal-directed message modification

The hypothesis was examined that previously demonstrated message modification and its subsequent social cognitive effects would be more characteristic of high than low self-monitors. Subjects first read an essay describing a stimulus person and were then requested to communicate a referential message concerning him to a listener who supposedly either liked (positive audience condition) or disliked (negative audience condition) the stimulus person. Subjects were subsequently given, after both a brief and long delay interval, a reproduction, impression, and attitude measure. The results indicated that high self-monitors were more likely to modify their message in a manner that was evaluatively consistent with their listener's attitude. In addition, this message modification had the predicted social cognitive consequences in that it affected the high self-monitor's subsequent impressions of (but not necessarily attitude toward) the target person. The results suggested that the responses obtained from high self-monitors in many experimental contexts may themselves be the results of a self-monitoring strategy. The implications of these results for research examining the effects of “self-monitoring” are discussed.     

A device that provides an eye-to-eye video perspective for interactive television

A device that allows individuals to engage in eye contact while interacting over two-way television is described. The apparatus consists of a television monitor and low light-level television camera housed within a cabinet containing a mirror system that resembles a combination beam splitter and periscope. Through the mirror system, the pick-up camera captures a reflected full-face eye-level image of the television viewer as he or she attends to the display monitor. The device is particularly useful for studying the nonverbal communication patterns of individuals engaged in social interaction.     

A Comparison of Nonverbal Compensatory Behaviors Within Direct Face-to-Face and Television-Mediated Interviews1

A study was performed to compare direct face-to-face and television-mediated interviews with regard to a hypothesized compensatory relationship between intimacy level of conversation topic and individuals' looking and smiling behaviors. Thirty-two male subjects were randomly assigned to one of two communication settings and asked a series of questions that varied according to topic intimacy. Subjects' looking, smiling, talking, and listening times were scored from videotapes made of the interviews. In support of predictions derived from Argyle and Dean's (1965) affiliative-conflict theory, it was observed that a shift in topic intimacy from low to high resulted in a decrease in the percent of time subjects spent looking at the interviewer. Further, the results of the present study replicated those reported by other investigators, indicating that a shift in topic intimacy (1) primarily affects subjects' looking while talking and not looking while listening and (2) does not affect subjects' smiling behavior. With the exception that more looking while listening occurred in the television-mediated interviews than in the direct face-to-face interviews, no differences were found in subjects' behaviors between the two communication conditions. The theoretical and practical implications of these results are discussed from the perspective of affiliative-conflict theory and its application to social interactions conducted via two-way television.     

A FAILED RECONCILIATION: FURTHER REFLECTIONS ON STERBA'S PROJECT

Although I do not find any of Sterba's responses to my recent criticisms of his work How to Make People Just convincing, I shall not attempt to answer them point by point since this would be a boring, scholastic exercise at best.1 Rather, I shall expand upon what I believe continue to be the three major problems with Sterba's theory and explain why his recent responses to my criticisms (and the criticisms of others) along these lines are not adequate.     

Physiology and Faith: Addressing the "Universal" Gender Difference in Religious Commitment

That men are less religious than women is a generalization that holds around the world and across the centuries. However, there has been virtually no study of this phenomenon because it has seemed so obvious that it is the result of differential sex role socialization. Unfortunately, actual attempts to isolate socialization effects on gender differences in religiousness have failed, as have far more frequent and careful efforts to explain gender differences in crime. There is a growing body of plausible evidence in support of physiological bases for gender differences in crime. Making the assumption that, like crime, irreligiousness is an aspect of a general syndrome of short–sighted, risky behaviors leads to the conclusion that male irreligiousness may also have a physiological basis. If nothing else, this article may prompt creative efforts to salvage the socialization explanation.     

The effects of the Positive Environment Program (PEP) on the behaviors of adults with profound cognitive and physical disabilities

This study evaluated the effects of the Positive Environment Program (PEP) on the behaviors of residents and staff in a state‐operated residential facility during a 2½ year period. The participants included 19 adult residents with profound cognitive and physical disabilities and 11 staff members who worked with them. Data were collected on alertness, leisure material availability, engagement, staff interactions, and resident affect during two samples of data collection six months prior to implementation of PEP. Training was then provided to staff on positive interaction skills. Following the training, researchers implemented a monitoring program and a staff incentive program. The results of this project showed improvements in staff interactions, resident interaction with leisure materials, improved levels of alertness, and increases in a ‘happiness index’. The benefits and limitations of this project as well as future research are discussed. Copyright © 2002 John Wiley & Sons, Ltd.
