Is construction reserved for the target during visual search?

R T Solman

    Perceptual and Motor Skills
    |February 1, 1975
    PubMed
    Summary

    High letter similarity impacts visual search. When irrelevant letters closely resemble targets, recognition memory is affected, suggesting construction may not be limited to targets.

    Area of Science:

    • Cognitive Psychology
    • Visual Perception
    • Human Memory

    Background:

    • Visual search involves identifying target stimuli amidst distractors.
    • Prior theories, like Neisser's (1967), proposed that cognitive construction during search is reserved solely for target identification.

    Purpose of the Study:

    • To investigate if highly similar irrelevant letters influence cognitive processing during visual search.
    • To determine if the construction process extends beyond target letters, challenging existing models.

    Main Methods:

    • Participants completed a visual search task using alphabet letter lists.
    • A recognition test assessed memory for irrelevant letters based on their frequency in the search lists.
    • Analysis of variance (ANOVA) was employed to analyze the data.

    Main Results:

    • A significant recognition frequency effect was observed.
    • The data indicated that irrelevant letters, particularly those similar to targets, were subject to cognitive construction.

    Conclusions:

    • The findings suggest that cognitive construction during visual search is not exclusively reserved for target identification.
    • Neisser's (1967) model may require modification to account for the influence of similar irrelevant stimuli on cognitive processing.
