To account for observed sex differences on tasks such as the rod and frame test, the embedded figures test, and other related measures, the theory is advanced that a sex-linked recessive gene mediates or facilitates certain performances. This assumption is coupled with the concept of "a mixture of density functions" to provide a…

Analyses found that: (1) the SAT predicts academic success more accurately for Black students in predominantly Black rather than White colleges; (3) the SAT predicts best for Black males in Black colleges but worst for Black males in White colleges; and (4) the SAT-GPA correlation is strongest for high-achieving Black students who focus on…

Concludes that a significant sex difference in coding performance favoring girls was discovered on two components of the Wechsler Intelligence Scale for Children. (RB)

Stepwise multiple regression was used to develop salary prediction equations, one from each of two faculty samples used most frequently used in this type of research. An analysis of the model found that on average women were paid significantly less than men. (RB)

First-year grade average was predicted from verbal and mathematical aptitude tests, standardized achievement tests in English, mathematics, and physics, and high school marks separately for males and females in order to study the sex differences in the predictability of academic achievement. The data came from five public universities over a…

Hostility scores, as measured by the Scrambled Sentence Test, were found to be statistically significant negative predictors of course achievement in a meteorology course at a military installation. (MS)

Children of 18 months classified as secure or insecure/avoidant by means of the Ainsworth Strange Situation were observed at home and in a playgroup. Teachers and observers rated girls classified as insecure/avoidant as being more difficult to deal with and having more difficulty with peers than girls rated as securely attached. (PCB)

Adolescents diagnosed with at least one mental disorder were studied to determine predictors of suicidal ideation and suicide attempts. Major depression was predictive of suicidal ideation and attempts for both genders. Chronic stress was found predictive of male suicidal ideations, while low self esteem and family dysfunction were predictive in…

Few meaningful sex differences will be reported if investigators go beyond the reporting of statistical significance to determine the indices of experimental effect size. Techniques for obtaining this type of information include the calculation of d and the estimate of omega squared, which indicate the advisability of continuing a line of…
