Description
The present investigation was undertaken to see if some daily eating habits would be related to personality traits by linear discriminant analysis. The results were as follows:
It was recognized that there was distinct relation between eating habits and each type of Y-G profils. Especially, both 2 groups of B (black list type) and E (excentric type) showed marked trend toward joyless during a meal or school lunch, too many likes and dislikes, too many eating between meals and so forth.
The estimation of linear discriminant function for Y-G profils with eating habits as predictor variables made it possible to classify the samples to 2 groups with correct ratios 75~100% (in case of male) or 66.7%~94.4% (female) in range, respectively.
Eating habits and personality traits were linked together, too. That is, the groups of less opportunity of having meals, joyless during a meal, too many likes and dislikes and too many eating between meals had tendencies to emotion-insecurity, social-maladjustment and social- or thinking-introversion.
These were established by discriminant analysis with lower misclassification ratio 0~30% in range.
