title: The effects of verbal and nonverbal contingent reinforcement upon the intelligence test performance of black adults.
abstract: This study examined the effects of contingent verbal and nonverbal reinforcement upon the intelligence test performance of bladk adults. Thirty-six Ss (half male and half female) were pretested on the Quick Test and then administered the complete WAIS under one of three treatment conditions: verbal reinforcement, nonverbal reinforcement or no reinforcement (control condition). Verbal reinforcement was administered as statements of "good" or "fine" by the E, while nonverbal reinforcement took the form of a nod of the head or a statement of "Mmhm." The primary analysis of the data indicated no significant differences between the treatment conditions.
