The effect of clients' family structure on nursing students' cognitive schemas and verbal behavior.

The primary purpose of this study was to investigate if nursing students stereotype clients on the basis of family status. In addition, the influence of information about the client's family status on students' predictions about the client's behavior, information sought from the client, recalled information, and verbal responses directed toward the client were examined. The participants were 83 nursing students from a large Midwestern university. They were randomly assigned to one of two groups. Brief written information about a female adult client with a vaginal discharge was provided and, after listening to an audiotaped interview between a nurse and the client, students completed a battery of questionnaires. They also responded verbally to questions asked by the audiotaped client. All information given to both groups was identical except for the client's family status. Results indicated that the client who was a married mother was perceived somewhat more positively than the unmarried mother client. Participants' perceptions were only somewhat consistent with cultural stereotypes about these family statuses. Information sought and information remembered about the client were greater when she was an unmarried mother. There were no differences in predictions of patients' behaviors and verbal responses.

Verbal behavior at a procedural level in the chimpanzee.

Ape language research has typically employed cognitive descriptions of ape competencies. Recently, Epstein, Lanza, and Skinner (1980) attempted to simulate some of the ape findings with pigeons. They also used cognitive terms to describe their results, but with "tongue-in-cheek." In the hope of bringing about a better understanding of the ape research, this paper describes the main aspects of one ape language project, using a behavior-analytic framework. It then briefly compares and contrasts, from that perspective, the training programs used with pigeons and with apes. It is concluded that the behavior-analytic framework, and the procedures devised to produce language skills in apes, provide strong support for several of the major positions set forth in Skinner's (1957) Verbal Behavior.

Effects of uninstructed verbal behavior on nonverbal responding: Contingency descriptions versus performance descriptions.

Undergraduates' button presses occasionally made available points that were exchangeable for money. Lights over left and right buttons were respectively correlated with multiple random-ratio random-interval components. During interruptions of the multiple schedule, students filled out sentence-completion guess sheets. When shaping of these guesses produced performance descriptions (e.g., "press slowly" for the left button and "press fast" for the right), button-pressing rates typically were consistent with the verbal behavior even when rates were opposite to those ordinarily maintained by the respective schedules. When shaping instead produced contingency descriptions (e.g., the button works "after a random number of presses" or "a random time since it worked before"), pressing rates were inconsistently related to the descriptions; for some students descriptions of ratio contingencies generated higher corresponding pressing rates than were produced by descriptions of interval contingencies, but for others contingency descriptions and pressing rates were unrelated.

A procedure for studying echoic control in verbal behavior.

Male and female college students answered standard questions about the women's liberation movement on three occasions. A set of target words was embedded in the questions, with one set used in Sessions 1 and 3, and a synonymous, but different set used in Session 2. The relative frequencies of usage of a given target word were directly related to whether the questions for that session contained the word. The results supported the hypothesis of echoics as proposed in Skinner's theory of verbal behavior.

Instructed versus shaped human verbal behavior: Interactions with nonverbal responding.

Undergraduate students' presses on left and right buttons occasionally made available points exchangeable for money. Blue lights over the buttons were correlated with multiple random-ratio random-interval components; usually, the random-ratio schedule was assigned to the left button and the random-interval to the right. During interruptions on the multiple schedule, students filled out sentence-completion guess sheets (e.g., The way to earn points with the left button is to...). For different groups, guesses were shaped with differential points also worth money (e.g., successive approximations to "press fast" for the left button), or were instructed (e.g., Write "press slowly" for the left button), or were simply collected. Control of rate of pressing by guesses was examined in individual cases by reversing shaped or instructed guesses, by instructing pressing rates, and/or by reversing multiple-schedule contingencies. Shaped guesses produced guess-consistent pressing even when guessed rates opposed those characteristic of the contingencies (e.g., slow random-ratio and fast random-interval rates), whereas guesses and rates of pressing rarely corresponded after unsuccessful shaping of guesses or when guessing had no differential consequences. Instructed guesses and pressing were inconsistently related. In other words, when verbal responses were shaped (contingency-governed), they controlled nonverbal responding. When they were instructed (rule-governed), their control of nonverbal responding was inconsistent: the verbal behavior sometimes controlled, sometimes was controlled by, and sometimes was independent of the nonverbal behavior.
