Research on naive physics and naive optics have shown that people hold surprising beliefs about everyday phenomena that are in contrast with what they see. In this article, we investigated what adults expect to be the field of view of a mirror from various viewpoints. The studies presented here confirm that humans have difficulty dealing with the…

Adult subjects viewed pictures at brief intervals, testing their reactions to informative objects--those not redundant with or predictive of the rest of the picture, such as a tractor in an underwater scene. Results indicated that observers fixate earlier, more often, and longer on informative objects. (Author/SJL)

In three experiments, this study addressed two basic questions about the detection of multiletter patterns: (1) How is the detection of a multiletter pattern related to the detection of its individual components? (2) How is the detection of a sequence of letters influenced by the observer's familiarity with that sequence? (Author/BW)

Three experiments employed rectangles in stimulus identification tasks. It was concluded that the initial perceptual processing of rectangles is accomplished by separate dimensional analyzers operating in parallel. Observers adopt different decision strategies for negatively correlated sets and for single dimension sets when the number of…

Two strings of letters were presented. Subjects were instructed to indicate whether the second string contained the same elements as the first, regardless of position. Reaction time increased with the number of positions that the letters were displaced. Results indicate that order may be an important factor in retrieval from memory. (Author/BW)

Four commissurotomy patients were tested for ability to match tachistoscopically presented stimuli with pictures in free vision, according to either structural appearance or functional/conceptual category. (Editor)

Earlier research with the lexical decision task led to the hypothesis that semantic context facilitates the encoding of words related to the context. Six experiments which employed different tasks (e.g., making a lexical decision) and different experimental paradigms (e.g., tachistoscopic exposures with masking stimuli) further investigated this…
