Extends M. C. Shaw and D. L. White's (see 39:5) investigation of the relationship of child-parent identification and academic underachievement by utilizing a wider range of intelligence scores and a different index of identification. 48 males were classified as either underachievers (UA) or achievers (A) based on the ratio of the prior year's cumulative GPA to their CTMM IQ score. UA and A masculinity-femininity scores derived from the Bell Adjustment Inventory were signficantly different (p < .01); no such differences were found between IQ levels or the interaction of IQ * Achievement. The findings extend Shaw and White's suggestion that male sex-role identification is characteristic of A but not of UA.
