Causal ambiguity and heterosexual affiliation

A male's decision to approach a physically attractive female stranger may be fraught with ambivalence. He is drawn by her beauty but he may fear rejection. The conflict lessens, however, if approach can occur under the guise of a motive other than desire to be with the attractive woman. This is because keeping one's true approach motive ambiguous may make direct personal rejection less likely. The effect of ambiguity on males' tendencies to approach females was explored in two experiments. In the first study, presented to subjects as a movie rating exercise, an excuse to sit with an attractive female confederate (a movie preference) was available to some subjects but not to others. As predicted, males only sat with the confederate when a reason for their affiliative behavior, other than her attractiveness, was available. In the second study, male-female dyads were run through the film rating paradigm with the female subjects in the role played by the confederate in Study I. The results of Study I were replicated for the dyads which included attractive females, as expected. The relationships between fear of failure and attributional ambiguity in social and achievement settings are examined. The tendency to discount a person's physical appearance as a cause of social behavior is discussed.     

The effects of special education labels on teachers' behavioral observations,checklist scores,and grading of academic work

This study addressed the question: Do special education labels bias teachers' evaluations of children? Thirty primary level teachers were given different labels for the same child: learning disabled, educable mentally retarded, emotionally disturbed, normal, or no label. Teachers made behavioral observations from the same video-tape, completed a checklist, and graded the same academic work purportedly completed by the target child. Teachers' behavioral observations and grading of the academic work were not influenced by the special education labels, but the checklist scores were. Implications for the philosophical debate about the effects of labeling and for methods of classroom data collection by teachers are discussed.     

A criminal offender introspective report.

The development of a new scale suitable for research with the criminal offender was described. Based on the factor analysis of an item pool delineating sociopathic personality traits, five factors were derived to compose an 80-item criminal offender introspective report (COIR).     

Generalization of teacher behavior as a function of subject matter specific discrimination training

The effect of training on the rate of behavior-specific praise for two fourth-grade teachers was investigated within a multiple-baseline design. Training teachers to identify instances of behavior-specific praise on videotaped presentations (discrimination training) combined with instructions to use praise, and audiotape recordings of the teachers' classroom interactions as feedback, increased the rates of behavior-specific praise. However, the effects were restricted to subject-matter areas in which training was conducted.     

Some variables affecting rate of key pecking during response-independent procedures (autoshaping)

Rate of key pecking by pigeons subjected to response-independent procedures in which a stimulus on the response key preceded food presentation was investigated in eight experiments. Color and shape of the stimulus, duration of the stimulus, probability of food following the stimulus, duration of the intertrial interval, and duration of food presentation were varied separately and in combination. All variables studied, except color and shape of the stimulus, had a reliable effect on pecking rate, but some variables had stronger effects than others. Rapid key pecking may be obtained with a variety of response-independent procedures, as well as by response-dependent reinforcement. The results of experiments in which food is both dependent on key pecking and correlated with stimulus conditions are not representative of simple operant effects. Key pecking is an ideal response for studying the simultaneous operation of response-reinforcer and stimulus-reinforcer effects.
