Ego development in perspective: Structural stage,functional phase,and cultural age-period models

Ego development is emerging as one of the more important areas of research in developmental psychology. This paper presents a structural stage approach to ego development and distinguishes it from two other models of ego development, which are termed functional phases and cultural ages. Two subtypes are also delineated within the structural stage approach—a monodomain and a multisubdomain—and the latter is argued for. These concepts are then illustrated through an analysis of four prominent ego development theories—those of Robert Selman, Robert Kegan, Jane Loevinger, and Erik Erikson. The important similarities and critical differences of the theories are clarified, which enables the authors to present a summary integration.     

Gender differences in implicit exposure to cyber-pornography

ABSTRACT

Cyber-pornography consumption has become a widespread behavioral habit, with potential diverse outcomes for the user. Previous studies have repeatedly found that males are exposed to cyber-pornography more than females, when they are asked about it explicitly. However, perceived social acceptance of cyber-pornography consumption may dramatically bias such explicit reports. The current study aimed at better understanding gender differences in exposure to cyber-pornography using both explicit self-report measures and a new measure developed to examine exposure to cyber-pornography indirectly. The findings demonstrated gender differences in exposure to cyber-pornography in both measures. Women tended to understate the extent of their exposure. Interestingly, men showed the opposite tendency. Lastly, perceived social acceptance mediated the relationship between gender and explicit report bias. We discuss the conclusions of the current study in relation to previous theories and findings, as well as the importance of using indirect measures to study socially controversial topics such as cyber-pornography.     

Difficulties Experienced by Women in Prison

This article assembles data that identify some problems experienced by women incarcerated in prisons in the United States. Inequalities in occupational and educational programs offered in women's prisons in comparison with those offered in prisons for men are discussed. The impact of inadequate health and mental health services on the lives of these women is explored, and separation problems encountered by the woman prisoner and her family are examined. Some recommendations for change are suggested.     

The interaction of oculomotor cues and stimulus size in stereoscopic death constancy.

In the natural world, observers perceive an object to have a relatively fixed size and depth over a wide range of distances. Retinal image size and binocular disparity are to some extent scaled with distance to give observers a measure of size constancy. The angle of convergence of the two eyes and their accommodative states are one source of scaling information, but even at close range this must be supplemented by other cues. We have investigated how angular size and oculomotor state interact in the perception of size and depth at different distances. Computer-generated images of planar and stereoscopically simulated 3-D surfaces covered with an irregular blobby texture were viewed on a computer monitor. The monitor rested on a movable sled running on rails within a darkened tunnel. An observer looking into the tunnel could see nothing but the simulated surface so that oculomotor signals provided the major potential cues to the distance of the image. Observers estimated the height of the surface, their distance from it, or the stereoscopically simulated depth within it over viewing distances which ranged from 45 cm to 130 cm. The angular width of the images lay between 2 deg and 10 deg. Estimates of the magnitude of a constant simulated depth dropped with increasing viewing distance when surfaces were of constant angular size. But with surfaces of constant physical size, estimates were more nearly independent of viewing distance. At any one distance, depths appeared to be greater, the smaller the angular size of the image. With most observers, the influence of angular size on perceived depth grew with increasing viewing distance. These findings suggest that there are two components to scaling. One is independent of angular size and related to viewing distance. The second component is related to angular size, and the weighting accorded to it grows with viewing distance. Control experiments indicate that in the tunnel, oculomotor state provides the principal cue to viewing distance. Thus, the contribution of oculomotor signals to depth scaling is gradually supplanted by other cues as viewing distance grows. Binocular estimates of the heights and distances of planar surfaces of different sizes revealed that angular size and viewing distance interact in a similar way to determine perceived size and perceived distance.
