The Effects of Response Repetitions on Sight Word Acquisition for Students with Mild Disabilities

Single response learning trials, defined in terms of the three-term contingency model, were compared with repeated response learning trials. The purpose of Study 1 was to assess the effectiveness and efficiency of single and repeated response learning trials on sight word remediation. In Study 1, one single response learning trial having one response opportunity per word was compared to one repeated response learning trial having five response opportunities. In Study 2, three single response trials were compared to three repeated response trials. In both studies, the training conditions were compared using an alternating treatments design. Measuring the cumulative number of sight words mastered showed the training conditions equally effective. However, measuring (a) the mean duration of training sessions, (b) the cumulative frequency of words mastered per session duration, (c) the mean number of training sessions per word required for mastery, and (d) the training time per mastered word showed that the single response condition was more efficient. Discussion focuses on the need to include training data when determining best practices for teaching.     

The detection of malingered mental illness

Clinical approaches to the detection of malingering are examined from the perspectives of both the general practitioner and forensic examiner. Specific strategies for identifying malingering patients is presented with particular attention to psychoses and post-traumatic stress disorders.     

Effects of high and low dosages of methylphenidate in children with strong and sensitive nervous systems

This investigation was undertaken to explore the possible causes and consequences of the finding that attention- and learning-disordered children with sensitive (weak) nervous systems were titrated at higher dosages of methylphenidate than those with strong nervous systems. Pretreatment parent and teacher ratings of hyperkineticassociated behavior were no different for children typed as having strong or sensitive nervous systems or for those subsequently prescribed higher or lower dosages by a child psychiatrist “blind” to their type as well as condition (drug or placebo). However, those titrated at lower dosages, regardless of whether strong or sensitive, were rated as more improved than those given higher dosages. Pretreatment reaction time (RT) data suggested that sensitive types prescribed low dosages had less of a problem sustaining attention, and placebo RT data suggested that strong types titrated at low dosages had more of a problem sustaining attention. A contrast of placebo and drug RTs showed that strong types titrated at lower dosages improved more than strong types given higher dosages, whereas sensitive types given higher dosages improved more than sensitive types given lower dosages. The latter finding is thought to add support to the theory of Gray (1964), who suggested that, paradoxically, the weak nervous system needs a more intense stimulus than the strong to reach the concentration threshold.     

Converging evidence for the functional significance of imagery in problem solving

Two kinds of explanations have been offered for the process by which three-term series problems are solved, one in terms of linguistic principles and the other in terms of visual-spatial imagery. Two experiments are reported in which three different classes of operations are brought to bear on the problem: (1) Manipulation of stimulus attributes (characteristics of problems), (2) manipulation of variables that selectively encourage or inhibit the use of imagery (facilitating instructions; the suppression of visualization by reading), and (3) measurement of relevant individual differences (spatial-reasoning ability). All of the results indicate that imagery plays a functional but not a necessary role in the solution of three-term series problems; it is suggested that imaginal representation is functional because it reduces the load on memory. An adequate explanation of problem-solving will have to address certain general issues, such as the diversity of forms of cognitive representation and differences within and between individuals in the choice of problem-solving strategies.     

The social play of two behaviorally disordered preschool children during four activities

The effect of contingent teacher attention on the social play of two behaviorally disordered preschool children was investigated. Using a multiple baseline design with reversal conditions, social play was measured on four activities: pegs and pegboard, athletic ball, blocks, and water pail. Baseline data indicated considerable variability in the amount of social play across the four activities. The initiation of the experimental contingency produced a dramatic increase in percentage of time in which the subjects engaged in social play. The implications of these results for the remediation of isolate behavior in young children with multiple behavioral deficits are discussed.     

Sex-role traditionalism and fear of success

In the present study 33 adult women completed Horner's measure of fear of success, filled out a questionnaire that tapped sex-role traditionalism and negative attitudes toward the women's liberation movement, and answered questions concerning their political beliefs and educational backgrounds. In line with some of Horner's contentions, it was found that fear of success is more common among nontraditional women — those who favor the women's movement, have more education, and hold liberal or radical political beliefs. Fear of success is not a correlate of traditional femininity but rather a sign of conflict experienced by ambitious, nontraditional women. Implications and further questions are discussed.     

The actor's behavioral history,his current role,and the divergence between actor and observer responsibility attributions

The actor's behavioral (High or Low) and role (High, Medium, or Low) respectability were varied in an actor-observer attribution study. A scenario described the actor's background combination of behavioral and role respectability and an event in which the actor participated. Subjects assigned actor and situational responsibilities to the event from their own viewpoint and from their perceptions of the actor's viewpoint. Subjects' awareness of the attributional divergence between actors and observers (Jones, E. E. & Nisbett, R. E. In Attribution: Perceiving the causes of behavior. New York: General Learning Press, 1971) and the information (public versus private) utilized by each were reflected in the results.
