Time estimation and time production in depressive patients.

T Kitamura, R Kumar

    Acta Psychiatrica Scandinavica
    |July 1, 1983
    PubMed
    Summary

    Depression impacts time perception, with patients showing altered estimations of short time intervals. This time distortion in depression may be linked to psychomotor retardation.

    Area of Science:

    • Psychology
    • Neuroscience
    • Psychiatry

    Background:

    • Time perception is crucial for daily functioning.
    • Depression is often associated with cognitive impairments, including altered time perception.

    Purpose of the Study:

    • To investigate time estimation and production in patients with depression.
    • To explore the relationship between depressive symptoms and time perception deficits.

    Main Methods:

    • Employed the Time Estimation Test (TET) and Time Production Test (TPT) on 23 depressive inpatients and matched controls.
    • Data collected across three 2-week intervals.

    Main Results:

    • Both groups improved time estimation for short durations over time.
    • Depressive patients showed greater overestimation of one short time span compared to controls.
    • Retardation symptom correlated with both time estimation and production scores.

    Conclusions:

    • Depression may affect the faculty of time perception, particularly for shorter durations.
    • The findings suggest a link between psychomotor retardation and altered time perception in depression.
