268 <strong>Educability</strong> <strong>and</strong> <strong>Group</strong> <strong>Differences</strong><br />

COMPETITION AND FAILURE THREAT<br />

Still another motivational theory of low Negro IQ <strong>and</strong> scholastic<br />

attainment, originally suggested <strong>by</strong> the experimental research of<br />

Irwin Katz (1964, 1968), holds that Negro test performance is<br />

depressed <strong>by</strong> a constellation of factors comprised of (a) failure<br />

threat - the Negro’s expectancy of a low probability of success in<br />

competition with whites or white norms on an intelligence test, <strong>and</strong><br />

(b) social threat -emotional responses of fear, anger, <strong>and</strong> humiliation<br />

that are presumably detrimental to performance <strong>and</strong> may be<br />

elicited <strong>by</strong> a white examiner, especially if the examiner is perceived<br />

as unsympathetic, supercilious, <strong>and</strong> authoritarian. Katz has tested<br />

these hypotheses experimentally <strong>by</strong> administering test-like tasks<br />

to Negro college students with <strong>and</strong> without instructions that it was<br />

or was not an intelligence test, that the testees were or were not<br />

competing with whites or white norms, with white or Negro<br />

examiners, threatening or friendly examiners, <strong>and</strong> with or without<br />

external threats such as strong electric shock. This research,<br />

although interesting <strong>and</strong> important in its own right, has unfortunately<br />

been misrepresented as indicating that these situational<br />

factors manipulated in Katz’s experiments affect Negro performance<br />

on st<strong>and</strong>ard intelligence tests <strong>and</strong> in situations that are<br />

typical of those in which intelligence tests are ordinarily administered<br />

(e.g., Watson, 1970). It has not been demonstrated that the<br />

effects hypothesized <strong>by</strong> Katz account for any of the Negro-white<br />

difference in IQ as measured <strong>by</strong> any of the st<strong>and</strong>ard individual or<br />

group administered tests of intelligence. Whether or not it is<br />

possible significantly to influence subjects’ performance on<br />

certain experimental tasks, specially selected for their sensitivity<br />

to distraction <strong>and</strong> emotional arousal, under conditions that<br />

are very atypical of ordinary intelligence testing (such as<br />

threatening instructors, examiners acting hostile <strong>and</strong> authoritarian,<br />

<strong>and</strong> threat of electric shock while performing the task) is not at<br />

issue.<br />

The several experiments of Katz <strong>and</strong> his co-workers (recently<br />

reviewed <strong>by</strong> Sattler, 1970)1did not use intelligence tests, but timed<br />

experimental tasks depending mainly on speed of performance,<br />

rather than mental power. Such speed tasks are known to be more<br />

sensitive to distractions, emotional states, <strong>and</strong> the like. One of the<br />

tests, for example, was simple arithmetic - but the subjects were
