    Summary

    Higher verbal fluency significantly increases primary-process thinking scores on the Holtzman Inkblot Test. This finding highlights the importance of considering speech output when interpreting psychological test results.

    Area of Science:

    • Psychology
    • Cognitive Science

    Background:

    • Primary-process thinking reflects primitive cognitive operations.
    • Verbal fluency, or speech output, may influence psychological test performance.

    Purpose of the Study:

    • To investigate the relationship between verbal fluency and primary-process thinking.
    • To examine how different levels of verbal productivity affect scores on the Holtzman Inkblot Test.

    Main Methods:

    • Forty-nine male university students participated.
    • Participants were assessed using the Holtzman Inkblot Test (Holt system).
    • Groups were categorized as high or low primary-process based on unlimited verbal productivity.

    Main Results:

    • Increased verbal productivity led to significantly higher primary-process scores.
    • Consistent differences in primary-process scores were observed between high and low primary-process groups across fluency levels.

    Conclusions:

    • Verbal fluency is a critical factor influencing primary-process thinking scores.
    • Clinicians should consider speech output levels when interpreting Holtzman Inkblot Test results.
