Comparison between Gorham's Proverbs Test and the revised Shipley Institute of Living Scale for a black population

A total of 278 black women (183) and men (95) were administered the Gorham's Proverbs Test and the Shipley Institute of Living Scale (revised). This study compared Abstract scores on the Gorham's Proverbs Test with Vocabulary and Abstract scores on the Shipley Institute of Living Scale. The two tests were remarkably similar in terms of score distributions and susceptibility to the effects of age, perceived socioeconomic level during childhood, education, and perceived quality of education. Analysis also showed that abstract reasoning, as measured by these tests, is not free from the effects of vocabulary skills. Mean scores on both tests were within the range of mean scores previously reported in the literature.
