RESUMO
The ability to infer the sex of the writer from cursive handwriting was examined under a range of conditions. In 5 experiments male and female college students were able to perform this task at the 75% accuracy level even with small amounts of material, sometimes only a single letter or a single geometric pattern. On the other hand, age of the writer was just barely discernible from handwriting. It was suggested that sex or gender is present in handwriting in much the same way as it is present in movement of the whole body.

This study replicated and extended the findings of MacCracken and Hayes (1976). 10 students were presented the same complex stereogram for 5 trials daily over 2 nonconsecutive days, and latencies to achieve depth perception were recorded. Latencies decreased across 5 trials in the first session but were somewhat longer at the beginning of the second session than at the end of the first session.

This study assessed perceptual learning effects with complex random-dot stereograms. Observers were shown the same complex anaglyph five times daily, for four consecutive days, and latencies to achieve stereopsis were recorded. Two-factor repeated-measures analysis of variance yielded significant effects of days, trials, and days-by-trials interaction. Latency to achieve stereopsis decreases over trials each day, but this decrease is not completely transferred across days. It is concluded that obervers must, in some sense, "re-learn" how to perceive complex stereograms if subsequent presentations occur over more than one day.
