“…Some years ago, various investigators found that the alignment of stimuli markedly affected the ease of making left-right discriminations ; left-right discriminations were difficult when the stimuli were side by side, but easy when the stimuli were one above the other (e.g., Huttenlocher, 1967). Similar effects of alignment have been found with adults (e.g., Wolff, 1971). However, left-right discrimination under these conditions could be explained as due to subjects' matching analogous parts (Barroso & Braine, 1974) rather than responding to a property of "leftness and Fisher (1979Fisher ( , 1980 that demonstrate that it is task characteristics rather than an inability to tell left from right that are responsible for the poor performance of preschool children on a left-right problem.…”

Recent work with adults suggests that inferior performance on left-right (relative to up-down) tasks is not a perceptual difficulty but is tied to the use of spatial words. This interpretation rests on the assumption that preschool children have difficulty distinguishing between objects turned left or right and that spatial words are acquired at the time that children experience left-right confusion. However, this assumption is unwarranted in the light of recent work showing that 3-year-old children make left-right discriminations when stimuli are presented individually. This study pursues the problem further by asking whether left-right discriminations can be made in the dark, without any perceptual supports. Preschool children solved left-right (and up-down) problems in a few trials, demonstrating their ability to make left-right discriminations based solely on an egocentric frame of reference.

“…The Hershenson and Ryder (Note I) finding, for example, EFFECTS OF ARRAY ORGANIZATION 33 of longer different response latencies to vertically symmetrical letter pairs than to vertically asymmetrical letter pairs accords nicely with the detrimental effect of pattern goodness on different responses found in the present experiments. Yet another example of the potentially harmful effects of array organization on different responses was reported by Wolff (1971). In this study, subjects were required to classify pairs of horseshoe stimuli as same or different.…”

Two experiments investigated the role of array organization in the simultaneous matching task. Multielement arrays of letters were arranged in either "good" or "poor" configurations and subjects were asked to determine whether all the letters were the same or if at least one was different. Correct "different" responses were slower when the letters were presented in good configurations than in poor configurations. Correct "same" responses, however, were not affected by the organizational quality (goodness) of the array. This effect of pattern goodness on matching performance was not affected by the confusability of the letters being compared. the relative eccentricity (spread) of the configuration. or the ratio of different letters present on different trials. The results suggest an encoding stage locus for the effect of pattern goodness and provide evidence supporting a two-process model of same-different judgments.

“…In this respect, it is important to note that reoent studies (Sekuler & Houlihan, 1968;Wolff, 1971) have shown that when adult subjects are required to classify pairs of horseshoe-shaped stimuli-presented in the horizontal plane-response time is longer for the left-right than for the up.<Jown reversal pair. But the reason why a form is more frequently confused with its left-right reversal remains unclear, and further research is needed to elucidate this point.…”
