Social uncertainty and interdependence: A study of resource allocation decisions in groups

Social uncertainty about the behavior of others with whom one is interdependent for rewards is hypothesized to encourage self-interested behavior and inhibit behavioral commitment to the group. This paper examines the roles of uncertainty, expectations, and feedback about other group members' contributions to the group in interdependent decision making. In the absence of feedback, resources tend to be divided between individual and group interests. Resource allocations to the group are found to increase significantly if group members receive feedback about other members' allocations, particularly if that feedback is at the individual level, not an aggregated group level. However, the effects of feedback presence and type are eliminated when group members state their expectations about other members' future contributions to the group. Implications for expectancy value theories of motivation and commitment to groups in organizations are discussed.

A novel automatic procedure for measuring ocular counterrolling: A computeranalytical method to determine the eye’s roll angle while subjects work on perceptual tasks

In investigations of the perception of space, the consideration of ocular counterrolling-the movement of the eye around its visual axis in response to body movement-is crucially important. The angle of this movement must be known in order for one to determine the precise retinal coordinates of a distal object. Following transformation, this stimulus serves as a reliable cue for visual direction. The otolith organs provide information about body tilt and are responsible for ocular counterrolling. A novel, noninvasive method to measure ocular counterrolling, based on the cross-correlation of digitized video pictures of the eyes, is presented. The resolution attained was ≤ 0.1°. The computer analysis is fully automatic and fast, and it can be performed while subjects work on perceptual tasks. No direct access to the eyeballs is required. Data from 4 subjects showing the counterrolling profile in various body positions are presented.     

Contributions of survey research to the understanding of memory

This article reviews the results of survey methodological research that illustrate phenomena of potential interest to investigators of memory, and also reviews psychological research designed to explore some of these phenomena under controlled laboratory conditions. We classify the phenomena reviewed into broad categories of remembering what events occurred, remembering when events occurred, and estimation and reconstruction processes used in reporting recurring events. We delineate the contributions of this research for our understanding of memory phenomena and show where this research has revealed gaps in our existing theories and knowledge. These findings present challenges for future collaboration between cognitive psychologists and survey methodologists.
