Measurement of lateral differences for faces in a two-response paradigm.

The experiments illustrated the effect of procedural factors in reaction time measurements on lateral differences between visual fields for faces in two-reaction paradigm. The subjects were instructed to decide whether two faces presented successively in the left or right visual field were the same or different. The two experiments differed in the situation of response buttons in horizontal line left-right (Experiment I), or in vertical line further-closer to the subject (Experiment II).

Hemispheric asymmetry in processing of verbal material by left-handers.

In our experiments we studied the laterality differences in a word-matching task for 16 strongly right-handed and 10 strongly left-handed female subjects. The results showed the right visual-field advantage for left-handers. Right-handed subjects performed the task faster than left-handed subjects.

The effect of distractor on memory for pitch: trace distortion or interference with retrieval?

The effect of the time of presentation of an interpolated stimulus on dynamic memory for pitch of pure tones of 900-2000 Hz was investigated by comparison of successive stimuli. The test tone followed the sample tone after 25, 40, 60, 80, 160 or 320 s. The interpolated stimulus (a pure tone of 220 Hz) was timed either 20 s before the test tone (Experiment I) or 20 s after the sample (Experiment II).
