Stimulus-response compatibility for absolute and relative spatial correspondence in reaching and in button pressing

Article Abstract:

Stimulus-response compatibility is demonstrated by improvements in accuracy and reaction times in experiments that preserve the spatial relationships between visual stimuli and response targets. This study utilized a button-pushing response task to measure the effect of changing the distance between the stimulus and response target.

Information and action in punching a falling ball

Article Abstract:

Research indicates that expansion velocity, or looming, is the optical variable an individual uses to begin and guide body movement in hitting a ball, rather than the variable of rate of change of optical expansion. Tests involved seated subjects, whose elbow joint angles were observed for flexion initiation in striking a dropped ball.

Location and attention

Article Abstract:

Studies suggest that the discrepancy in psychology literature regarding visual localization accuracy and attention is a result of coarse coding of location response in a 1992 study that used an inattention paradigm. The studies identifying the cause consisted of specific attention conditions, including divided attention, inattention and control, and differed from the 1992 study by adding the expectation of performing a location response.
