BRIEF REPORT: SELECTIVE BREEDING FOR PRINCIPAL COMPONENTS AND FACTORS BASED UPON BEHAVIORAL TRAITS

Area of Science:

• Psychology
• Personality Psychology
• Psychometrics

Background:

• Investigating the taxonomic structure of personality is crucial for understanding human traits.
• Existing personality trait systems, such as those by Guilford and Cattell, offer valuable frameworks.
• Integrating these systems can provide a more comprehensive understanding of personality structure.

Purpose of the Study:

• To conduct a taxonomic investigation of personality structure.
• To analyze the factor structure of a combined matrix of 600 personality questionnaire items.
• To examine the relative contributions and relationships between the Guilford and Cattell personality systems.

Main Methods:

• Utilized a matrix of 600 personality questionnaire items.
• Items were equally represented by marker items from Guilford's and Cattell's personality trait systems.
• Factor analysis was applied to the total matrix to determine the underlying factor structure.

Main Results:

• The study outlines the project and focuses on the factor structure of the total item matrix.
• Initial findings concern the relative contributions and interrelations of the Guilford and Cattell systems within the combined structure.
• This report serves as the first in a series, with subsequent reports detailing separate factor analyses.

Conclusions:

• The combined analysis provides an initial overview of personality structure integrating two major systems.
• Understanding the interplay between Guilford and Cattell markers is key to refining personality taxonomies.
• Further detailed analyses will elucidate the specific factor structures within each system.
