Cognitive impenetrability of memory for orientation.

R E Frederickson, J C Bartlett

    Journal of Experimental Psychology. Learning, Memory, and Cognition
    |April 1, 1987
    PubMed
    Summary

    Visual long-term memory for picture orientation relies on a viewer-centered frame. Memory recall is better using left-right directions than environmental references, confirming egocentric constraints.

    Area of Science:

    • Cognitive Psychology
    • Visual Perception
    • Memory Research

    Background:

    • Visual long-term memory is crucial for object recognition and navigation.
    • Understanding the reference frames used in memory is key to cognitive science.
    • Previous research has explored egocentric and environmental frames in spatial memory.

    Purpose of the Study:

    • To investigate whether memory for lateral orientation of pictures is constrained by a viewer-centered (egocentric) or environmental reference frame.
    • To determine the dominant reference frame influencing recall of object locations within visual scenes.

    Main Methods:

    • Experiment 1: Participants verbally encoded and recalled object locations in pictures using viewer-centered (left-right) and environmental (room features) frames.
    • Experiment 2: Participants viewed pictures directly and mirrored, then classified orientations using viewer-centered and environmental definitions.

    Main Results:

    • Verbal recall of object locations was superior using viewer-centered left-right directions compared to environmental relative proximities.
    • Picture orientation classification was significantly better with a viewer-centered definition of 'same orientation' than an environmental one.

    Conclusions:

    • Memory for lateral orientation of pictures is primarily constrained by a viewer-centered egocentric reference frame.
    • This finding supports the hypothesis that visual long-term memory utilizes an egocentric framework for orientation.
    • The viewer's perspective significantly influences how spatial information, including picture orientation, is encoded and retrieved from memory.
