Impacts of artificial intelligence on organizational decision making

Of all of the new technologies emerging in the late 20th century, the production of artificial intelligence may provide the most profound impacts on organizational decision making. Because the development of artificial intelligence technologies and models has largely been based on psychological models of human cognition, the effects of their implementation in complex social settings have not been thoroughly examined. This paper is an attempt to generate research which will develop a comprehensive understanding of the impacts of artificial intelligence and its role in complex organizations. A set of 11 hypotheses has been developed which examine the relationships between artificial intelligence technologies and the dimensions of organizational decision making. It is argued here that the implementation of expert systems will lead to less complex and political decision processes, while the implementation of natural language systems will lead to more complex and political decision processes.     

Reliability assessment of pedometer activity measurements

Pedometers (step counters) are inexpensive devices for obtaining naturalistic activity measurements. The existing reliability literature on pedometers is inconsistent. This article presents reasons for the disparity including (a) distinguishing between instrument reliability (Experiment 1) and clinical repeatability (Experiments 2–4) and (b) discussing methods of evaluating the reliability of activity measuring instruments. Experiment 1 shows that pedometer measurements have an uncertainty of approximately 5% (the test-retest correlational equivalent of .97) under laboratory conditions. Experiment 2 shows that pedometer measurements in college students walking a measured half-mile have approximately the same uncertainty. Experiment 3 shows that pedometer measurements from normal children walking a measured half-mile have an uncertainty of approximately 18% (the correlational equivalent of .91), while measurements from mildly hyperactive children have an uncertainty of approximately 29% (the correlational equivalent of .84). Experiment 4 shows that electronic step counters have an uncertainty of approximately 9% in normal and mildly hyperactive children and about 12% in clinically hyperactive children.     

Preventing Nuclear War: Beliefs and Attitudes as Predictors of Disarmist and Deterrentist Behavior1

A survey of peace activists, defense industry workers and psychology students (n= 283) was conducted to evaluate the usefulness of Protection Motivation Theory (Maddux & Rogers, 1983; Rogers, 1975) for predicting the extent and direction (Disarmist vs. Deterrentist) of respondents' efforts to prevent nuclear war. Regression analyses showed that the Protection Motivation model did account for a significant proportion of the variance in disarmist behavior, and that extending the model to include a measure of belief in the inevitability of war improved the model's predictive power. The model did not predict deterrentist advocacy, an outcome that suggests that activism in support of nuclear deterrence may be a response to a perceived threat from an “enemy” rather than a response to the threats represented by nuclear weapons and preparations for war.     

Time-out with children

The purpose of the present study was twofold: (a) to determine the effect of an explanation prior to or after time-out on child compliance and on child disruptive behavior during time-out and (b) to determine the effect of brief parent training in time-out on child and parent behaviors. Thirty-two mother—child pairs served as subjects and were assigned to one of the following four groups: control, time-out only, explanation prior to time-out, or explanation following time-out. Each mother—child pair was observed for one session under pretraining, training, and posttraining conditions. The results indicated that time-out significantly increased compliance but the addition of an explanation did not further alter the effectiveness of time-out. Training in the use of time-out decreased the incidence of maternal interruptions but did not affect maternal responses that were not trained. Finally, following brief time-out training for noncompliance, the mothers used the procedure only 50% of the time following noncompliance.This study was supported in part by a University of Georgia Research Council grant.     

Effects of relative nurturance and social power on observational learning and imitation

Preschool children observed two models, one of whom (controller of resources) controlled rewards dispensed to the child and to the other model (rival consumer of resources). The nurturance of the controller was varied in terms of his relative generosity towards the subject and rival consumer. Controllers were imitated to a greater extent than consumers only when the controller had been more nurturant to the child than to the rival consumer. Imitation of the controller and consumer were affected differently by the various conditions of nurturance, but children's learning of each model's behaviors were affected similarly by the conditions. The learning and imitative performance of each model's behaviors were uncorrelated, and imitation of one model did not correlate with imitation of the other. However, the learning of the two models' behaviors was highly correlated.     

Movement and illumination factors in adaptation to prismatic viewing

While wearing laterally displacing prisms, Ss were required to align a spot of light to the phenomenal straightahead. These measurements were obtained at the beginning and at the end of an exposure to prismatic displacement. In addition, Ss either actively controlled movement of the spot of light, or movement was manipulated by E under the direction of the S. Aftereffects were determined by having S position the spot of light with normal vision at the beginning of the experiment and after each measurement obtained under prism viewing. Ss in the darkened room condition who were required to align the spot of light actively showed a significant aftereffect in the direction of prismatic displacement both at the beginning and at the end of the exposure period. No difference in the degree of adaptation was found between those measurements at the beginning and at the end of the exposure period. No significant aftereffects were found when the room was illuminated during prism exposure or when E controlled movement of the light source.
