Objective: To investigate the effect of body weight support on the gait of hemiparetic subjects walking on a treadmill. Design: Survey. Patients: Eleven nonambulatory hemiparetic subjects. Methods: Subjects walked on the treadmill with full weight bearing and with 15%, 30%, 45%, and 60% body weight support at constant walking velocity. Cycle parameters, symmetry ratios, and the kinematic EMG of several lower limb muscles of the affected leg were recorded. Video-analysis served for assessment of posture and hip and knee angle displacement. Results: With body weight support the relative double support time decreased, the relative single stance period of the affected limb increased, and the functional activity of the vastus and soleus diminished. The activity of the gluteus tended to increase. Patients walked more upright and with less hip and knee flexion. The extensor spasticity did not change and the qualitative activation pattern of all recorded muscles remained unchanged. Conclusion: Body weight support did not facilitate a less physiological gait. By reducing double support duration, body weight support resulted in a greater stimulus for balance training. The facilitation of gluteus medius is favorable with respect to training pelvic alignment. The reduction of the activity of other antigravity muscles suggests a limit of 30% BWS not be exceeded.

This study examines ratings of self and partners by high and low tested lonely college students following brief interactions with opposite sex strangers. Results replicate and extend previous findings, indicating more negative evaluations for high as compared to low lonely subjects in self ratings, ratings expected from partners; and for men only, ratings of partners. High lonely men were rated more negatively than low lonely men but the corresponding effect for women was not observed. The data also indicate that high lonely participants were perceived by their partners as more likely to rate themselves negatively. The findings are discussed in relation to the probable consequences of perceived social skill inadequacies for the experience of loneliness.

The Psychological Abstracts for a six‐year period, 1980‐1985, were reviewed as a way to measure the growth of psychological interest in mediation. Two hundred and thirty dispute‐resolution abstracts were categorized and analyzed. There was 1 abstract in 1980, 37 in 1983, and 110 in 1985.

The Psychological Abstracts for the years 1986-1 989 were reviewed in order to compare psychologists' interests in mediation-related topics to the patternsfound in theyears 1980-1985, when there were 230 dispute resolution citations in the Psychological Abstracts. For the 1986-1 989 period, 294 dispute resolution abstracts were found. The annual rate decreased consistently )om 104 citations in 1986 to 43 in 1989.
