Forward and backward tactile recognition masking.

J H Kirman

    The Journal of General Psychology
    |July 1, 1984
    PubMed
    Summary

    Tactile masking, which affects object recognition, differs between forward and backward masking. Forward masking relies on peripheral processes, while backward masking involves both peripheral and central processes.

    Area of Science:

    • Neuroscience
    • Psychology
    • Sensory Perception

    Background:

    • Tactile recognition masking is a phenomenon where the perception of a tactile stimulus is impaired by the presence of other stimuli.
    • Understanding the mechanisms of tactile masking is crucial for comprehending sensory processing and perception.

    Purpose of the Study:

    • To investigate the characteristics of forward and backward tactile recognition masking.
    • To determine the influence of stimulus duration and interval on tactile masking effects.
    • To differentiate the underlying neural processes involved in forward and backward tactile masking.

    Main Methods:

    • Utilized a 15x15 tactile point-stimulator array to present line segment targets (varying location and orientation) and random-dot masks.
    • Manipulated target and mask durations, as well as interstimulus intervals (0-300 msec).
    • Recorded participant performance in recognizing tactile targets under different masking conditions.

    Main Results:

    • Increasing target duration relative to mask duration reduced forward masking but not backward masking.
    • Slightly increasing mask duration relative to target duration enhanced both forward and backward masking.
    • Further increases in mask duration significantly enhanced backward masking, with no effect on forward masking.

    Conclusions:

    • Forward tactile masking appears primarily influenced by peripheral neural processes.
    • Backward tactile masking is likely mediated by a combination of peripheral and central neural processes.
    • Findings align with similar masking phenomena observed in visual and auditory systems, suggesting shared underlying mechanisms.
