Effects of assertive training on three dimensions of assertiveness

The relative effectiveness of several components of an assertive training program in shaping assertive responses on three dimensions of assertiveness (refusal, investigatory, commendatory) was assessed. Thirty-two unassertive females were randomly assigned to one of four experimental groups: coaching plus behavior rehearsal plus modeling, coaching plus behavior rehearsal, behavior rehearsal plus modeling, and placebo control. Five behavioral and three self-report inventories were used as dependent measures. Coaching plus behavior rehearsal appears to be the most essential treatment components. Training was effective in improving assertiveness on all three dimensions.     

THE EFFECTS OF A GOOD-BEHAVIOR CONTRACT ON THE CLASSROOM BEHAVIORS OF SIXTH-GRADE STUDENTS1

The effects of a good-behavior contract on the on-task behavior, disruptive behavior, daily assignment completion, and weekly grades of four sixth-grade students were examined in a public school classroom. The contract consisted of presenting the students with a list of good conduct and assignment completion goals and a list of disruptive behaviors coupled with a list of rewards and penalties that could be earned. The rewards and penalties made use of existing facilities and classroom privileges. At the beginning of each morning work period, the teacher negotiated the good-behavior contract with each experimental subject. During the negotiations, the teacher emphasized student self-management and encouraged each student to earn a reward by achieving the good-conduct goals and completing the contract assignments. An isolated work area was provided to allow students the opportunity to remove themselves from their desks for a fixed period of 15 min. At the end of the work period, the teacher determined whether each student earned a choice of reward or penalty dependent on assignment completion and whether the teacher had observed disruptive behaviors. Thus, the contract permitted the student to negotiate the goal behaviors and contingencies with the teacher. Throughout the study, the students were in agreement with the teacher on whether a choice of reward or penalty had been earned. The contract was introduced for different children at different times, constituting a multiple-baseline analysis. On-task behavior and daily assignment completion increased, weekly grades were higher, and disruptive behavior decreased when the contract was in effect. Three contrast subjects were selected from the class as model students who consistently produced acceptable assignments and who did not engage in high rates of disruptive and/or off-task behaviors. When the contract was in effect for the experimental subjects, their performance compared favorably with the contrast subjects, who never received the daily contract. The results demonstrated that the contract was effective within the confines of the facilities and contingencies readily available in a public school classroom setting.     

Self-monitoring and self-reinforcement processes in a pre-transsexual boy

Young boys with normal male physical status who manifest feminine gender-role behavior and verbalize a cross-gender identity are high-risk for later adult sexual adjustment problems, e.g., transsexualism and homosexual conflicts (Bakwin, 1968; Lebovitz, 1972; Stoller, 1968; Zuger, 1966). In the only published experimental treatment studies on child gender disturbance in which replication procedures were used, Rekers and his colleagues empirically demonstrated external stimulus control and reinforcement control over pronounced feminine behavior in young boys with serious gender identity and behavior disturbance (Rekers and Lovaas, 1974; Rekers, Lovaas and Low, 1974; Rekers, Willis, Yates, Rosen and Low, in press; Rekers, Yates, Willis, Rosen and Taubman, 1976). To potentially minimize the previously reported stimulus specificity of the extrinsic reinforcement effects, this study introduces, for the first time, behavioral self-control strategies to decrease feminine behavior in a cross-gender identified boy. A 6-year-old boy was taught to self-monitor his own sex-role behavior, and then to self-reinforce gender-appropriate responding. A behavioral cueing procedure was used during the initial phases of the training of self-monitoring.     

Object disappearance and error in Piaget's Stage IV task

Piaget attributes perseverative error in infant manual search to the failure of the infant to conceive of objects as permanent entities which retain their identity when hidden at successive locations A and B. An experiment was performed to test this explanation in which search was compared under three conditions: when the object was hidden at A and B, when the object was covered but visible at A and B, and when the object was visible and uncovered at A and B. Errors occurred under all three conditions taking the form of a conflict in which infants searched persistently either at A or at B. The conflict was at a maximum when the object was hidden, but was evident even when the object was visible but covered. It is suggested that errors may reflect lack of coordination between egocentric and visual frames of reference in relation to which the object is located.     

Effects of differential reinforcement and task difficulty on preschoolers' compliance with teacher instructions

Preschool children in day schools were given instructions to complete certain tasks. Four tasks were given of two types and two levels of difficulty. In each condition compliance with at most one instruction (one task) was reinforced. In two similar experiments, with six children, general results were: compliance with easy tasks was maintained without reinforcement when any task compliance was reinforced; compliance for hard tasks remained high only when that specific task was reinforced. Thus, generalization of compliance with instructions varied with task difficulty. The setting and procedure for both studies were designed to reduce possible coercive features of laboratory studies of generalized performance. Results show generalized performance can occur under naturalistic conditions. The effect of effort, as a response characteristic affecting generalized performance, is discussed.     

Sex,masculinity—feminity,and intelligence

Masculine and feminine subgroups of males and females were selected from samples of high school and college students on the basis of composite scores from several M—F scales. They were compared on intelligence as measured by a verbal test, Terman's Concept Mastery Test, and a nonverbal test, D-48. Results did not support previous findings of sex differences in intelligence but showed that masculine subgroups of both sexes scored higher of the nonverbal test.     

Comparison of child and adult vibrotactile thresholds as a function of frequency and duration

Psychophysical thresholds for the detection of sinusoidal vibration of the thenar eminence of the hand were determined for children and adults. The subjects in the child group were between 8 and 11 years old, and the adults were between 20 and 39 years old. Measurements were made for vibration frequencies ranging from 18 to 700 Hz and stimulus durations ranging from 28 to 1,000 msec. For both children and adults, thresholds were a Il-shaped function of stimulus frequency. However, the exact form of the function was influenced by the age of the subjects. At frequencies above 200 Hz, thresholds were virtually identical for children and adults, but below this frequency children were more sensitive than adults. This finding, in combination with known changes in the anatomy of the Pacinian corpuscle with age, is in agreement with a filter model of this cutaneous receptor. Furthermore, variation of stimulus duration resulted in data in agreement with the theory that two classes of mechanoreceptors, Pacinian and non-Pacinian, mediate the perception of vibration.     

Imitative Behavior as a Function of Success-Failure and Racial-Socioeconomic Factors1

This study examined whether success-failure experiences, race, and social class are related to the likelihood that young children will engage in imitative behavior. Black subjects imitated significantly more than white subjects on a pre-experimental measure of imitation. Analysis of a difference score between pre- and post-experimental measures of imitation indicated that prior success was associated with less imitation than failure or a neutral condition. In addition, a white model was imitated significantly more than a black model in both the failure and the success conditions, with little difference between models in the neutral condition. No significant difference was found between the nondeprived and deprived groups. The results were discussed in terms of an outer-directedness hypothesis.
