The Symmetry of Constructed Patterns

ABSTRACT
- Patterns were obtained from mental-hospital patients of various categories by a technique akin to that of the mosaic test but simpler and more delimited.
- An objective method of quantifying the level of symmetry was devised.
- The symmetry-scores so obtained showed a high degree of reliability.
- Inquiry was made into the effects on symmetry-level of differences in sex, intelligence and degree of social adjustment among relatively well-behaved patients. The effects of severe behavioural pathology were also investigated. Intelligence was shown to be the major factor in determining symmetry-level. Females tended to have lower symmetry-scores than males. Degree of social adjustment had no significant effect. Severe behavioural pathology tended to lower symmetry-scores and this was interpreted as essentially a cognitive phenomenon.
- Various findings in regard to the relationship between symmetry of shape and symmetry of colour were recorded.
- The reasons for the findings were discussed.
