CHANGES IN THE FACIAL PROMINENCE OF WOMEN AND MEN OVER THE LAST DECADE

Two studies measured the facial prominence of women and men in popular images over the last decade. The first study used 1,200 photo-graphs from Time and Newsweek for the years 1970 and 1980. The results indicate that overall, men have received greater facial prominence than women, and facial prominence has increased over the decade. Only for Newsweek did women show a significantly greater increase in facial prominence than men. The second study used 640 photographs from Good Housekeeping and Ms. for the years 1974 and 1984. The results show that overall, men have received greater facial prominence than women, and facial prominence has risen over the decade, although not by much. In Ms. , women but not men gained; in Good Housekeeping , women gained slightly, but not as much as men. The results are consistent with earlier reports of an asymmetry in representation of men's and women's faces and suggest that this asymmetry is slowly diminishing.     

The valence of dreams reported by type A-B college students

The valences of the dreams reported by Type A (n = 39) and Type B (n = 42) undergraduates were examined. Consistent with the view that in part the manifest content of the dream may reflect attempts to manage stress, the Type A students were significantly more likely than the Type B students, to report disturbing dreams.     

Orientation-specificity in kinesthetic spatial learning: The role of multiple orientations

In the current study we tested whether multiple orientations in kinesthetic learning affected how flexibly spatial information is stored and later used in making location judgments. Three groups learned simple routes by walking them while blindfolded, with (1) multiple orientations achieved through normal walking, (2) multiple orientations achieved through backward walking, or (3) a single orientation achieved through walking without turning (which required forward, backward, and sideways walking). When subjects had experienced multiple orientations while learning the routes, later directional judgments were equally accurate (and equally rapid) regardless of whether the judgments were aligned or were contra-aligned with the orientation of the routes as originally learned. In contrast, when routes were learned in a single orientation (without turning), subsequent judgments on contra-aligned trials were both less accurate and slower than judgments on aligned trials. Thus, multiple orientations are important to establish orientation-free, flexible use of spatial information in a kinesthetic learning environment. This contrasts with the pattern of results typically found in visual spatial learning and suggests that the factors that affect orientation specificity of spatial use may differ across spatial modality.     

Synthesized clustering: A method for amalgamating alternative clustering bases with differential weighting of variables

In the application of clustering methods to real world data sets, two problems frequently arise: (a) how can the various contributory variables in a specific battery be weighted so as to enhance some cluster structure that may be present, and (b) how can various alternative batteries be combined to produce a single clustering that best incorporates each contributory set. A new method is proposed (SYNCLUS, SYNthesizedCLUStering) for dealing with these two problems.We wish to thank Anne Freeny and Deborah Art for their computer assistance, and Ed Fowlkes for his helpful technical discussion. We would also like to acknowledge the insightful and helpful comments from the editor and reviewers.     

Effect of anesthetic drugs on time production and alpha rhythm

Ss produced time intervals before and during inhalation of low concentrations of anesthetic gases. The drugs increased time productions by raising the slope of the line representing produced against objective time. Alterations in time production were not accompanied by consistent changes in alpha rhythm, respiratory rate, heart rate, or body temperature. The findings argue against the’ alpha rhythm’s acting as the biological pendulum for the internal clock.
