One hundred adult subjects rated themselves on nineteen 'oral pessimism' character traits. These ratings were correlated with the time of weaning from the breast. A statistically significant correlation was obtained indicating that weaning during the first four months of life tends to be associated with a conscious self-image that emphasizes 'oral pessimism' character traits in adult life. Adult subjects weaned late, that is, after nine months, tend to see themselves as relatively weak in 'oral pessimism' traits.
