Relation of Age of Onset to the Type and Severity of Child and Adolescent Conduct Problems

In a cross-sectional household sample of 9-through 17-year-old youths from 4 U.S. communities, youths with earlier ages of onset of conduct problems engaged in more conduct problems than youths with later ages of onset when current age and gender were controlled. Specifically, youths with earlier ages of onset were more likely to engage in several types of physical aggression, frequent lying, theft, and vandalism and were less likely to engage in only truancy. There also was an inverse relation between age of onset and level of functional impairment, mental health service use, and meeting diagnostic criteria for conduct disorder, attention-deficit hyperactivity disorder, and oppositional defiant disorder. Within the limits of cross-sectional data, these results support the hypothesis that key aspects of the heterogeneity of conduct problems among youths are related to the age of onset of conduct problems.     

TEACHING JANITORIAL SKILLS TO THE MENTALLY RETARDED: ACQUISITION,GENERALIZATION, AND MAINTENANCE

A task analysis of janitorial skills required for cleaning a restroom was performed. Six subtasks with a total of 181 component responses were identified. Subjects were required to progress through a series of four prompt levels ordered generally from more to less direct assistance for 20 of the most difficult component steps. Another series of four prompts, ordered from less to more direct assistance, was used to teach the other 161 responses. Subjects progressed to the next more intense prompt level contingent on a failure to respond appropriately with less assistance. A multiple baseline across subjects as well as the six subtasks was employed to evaluate the efficacy of the procedures. Six moderately retarded adolescents were trained in their public school. The results show rapid response acquisition, skill generalization to a second restroom, and maintenance of the newly learned behavior. The present research provides evidence of a model for analyzing and training vocational skills to the mentally retarded.     

Adapting chronometric tests for field studies of cognitive ability

This study was designed to examine the relationship of hand preference to performance on a thumb-positioning task. Two hypotheses were proposed on the basis of hemispheric lateralization. The first stated that all subjects would perform the task more accurately using the left thumb, regardless of hand preference. The second hypothesis tested was that left-handed subjects would perform more accurately than right-handed subjects. Each of 20 neurologically intact adults grouped by hand preference reproduced a criterion thumb position with both thumbs simultaneously. Absolute error, recorded for each movement and analyzed by mixed analysis of variance, did support the first hypothesis. However, the left-handed group did not perform statistically differently from right-handed subjects. Factors influencing the data are discussed and recommendations for further studies are made.     

Effective remote staff training of objective session notes

Session notes are a required component of documenting behavior analytic sessions. The direct training of writing objective session notes is important to the success of direct line staff completing adequate documentation and meeting requirements set forth by agencies, certification boards, and insurance funders. However, in‐person training is not always immediately available due to contextual restrictions. This study evaluated the effectiveness of implementing the teaching interaction procedure when training staff remotely to objectively document client progress within session notes. Three Registered Behavior Technicians? (RBT®s) were trained via telehealth to complete session notes objectively. Results showed that all 3 participants met the mastery criterion during probes measuring the objective documentation of home‐based behavior analytic sessions. These findings suggest that a training package, such as the teaching interaction procedure, can be effectively implemented remotely when conducting staff training.     

A quantitative analysis of accuracy,reliability and bias in judgements of functional analyses

Functional analysis can be considered a diagnostic assessment that behavior analysts use to determine behavioral function. Such a diagnosis ultimately requires a yes or no decision (i.e., a variable maintains a behavior, or it does not) that is determined by both subjective (clinical judgement) and objective (data) variables. Accurate and reliable identification of function is essential for successful treatment, yet behavior analysts' interpretation of data relies on their ability to detect visual differences in graphed data. Some research indicates that behavior analysts have questionable reliability in their visual analysis. To further examine the reliability, accuracy, and bias in visual analysis of functional analysis graphs, we simulated functional analysis results and surveyed 121 BCBA-Ds experienced in visual analysis. We then examined reliability of responses and used a signal detection theory approach to analyze accuracy and bias. Findings suggest that reliability and accuracy of judgements are questionable, and exploration of decision aids is warranted.     

The Development of a Measure of Irrational/Rational Beliefs

The Attitudes and Belief Scale-2 (ABS-2) developed in the late 1980s, is a measure of Ellis’ irrational and rational beliefs. Although no publication has described the instrument and it has only appeared in conference presentations, many researchers have used the ABS-2 to test REBT. This article describes the development of the ABS-2 and the original research on its psychometric properties. The scale has three factors that represent 24 different cells in a 4 × 2 × 3 factorial model. The first factor, Cognitive Processes, reflects Ellis’ concepts of Demandingness, Awfulizing, Frustration Intolerance, and Self-Downing. The second factor covers irrationally worded items versus rationally worded items. The rationally worded items were written to counter the irrational beliefs. The third factor includes content or life themes about which the person could be concerned, and includes Achievement, Affiliation, and Comfort. The ABS-2 generates a Total Score, a Total Irrationality Score, a Total Rationality score, and Scales scores representing each of the four Cognitive Processes domains and each of the three Content domains. The ABS-2 scores demonstrate adequate to excellent internal consistency, and correlate significantly with measures of depression, anxiety, life satisfaction, selfcontrol, well-being, and measures of internalizing personality disorders. The ABS-2 did not correlate significantly with measures of anger, externalizing personality disorders, mania, and somatoform disorder. An exploratory factor analysis provided weak support for the factor structure of the scale. The ABS-2 scores distinguish between normal and clinical samples. Rationally worded items discriminated between clinical and nonclinical groups much better than did the irrationally worded scales, suggesting that instruments that only assess irrational beliefs might underestimate the support for REBT.     

Boys don't cry: Cognitive load and priming increase stereotypic sex differences in emotion memory

The results of three experiments provide evidence that the relative accessibility of stereotypes about sex difference influences people's memory of very recent emotions. Being under high rather than low cognitive load caused females compared with males to recall experiencing more intense emotional reactions to saddening stimuli (Experiments 1 and 2), and relatively less intense reactions to angering stimuli (Experiment 2). Being directly primed with stereotypes about sex differences and being under high cognitive load both caused females to recall more intense reactions to saddening stimuli compared with females who were neither primed with stereotypes nor under cognitive load (Experiment 3). These results imply that the relative accessibility of stereotypes influences memories of emotion in a manner similar to stereotypes' influence on social perception. Implications of these findings for theories of emotion memory and for self-perpetuating stereotypes about emotional sex differences are discussed.     

A COMPARISON OF DISCRETE TRIAL TEACHING IMPLEMENTED IN A ONE‐TO‐ONE INSTRUCTIONAL FORMAT AND IN A GROUP INSTRUCTIONAL FORMAT

Discrete trial teaching (DTT) is a systematic form of intervention commonly implemented with children and adolescents diagnosed with autism spectrum disorder. Experimenters and clinicians have implemented DTT in both one‐to‐one instructional formats and group instructional formats to teach a wide variety of skills to children and adolescents diagnosed with autism spectrum disorder. The purpose of this study was to compare DTT implemented in a one‐to‐one instructional format with DTT implemented in a group instructional format in order to determine which format was more effective, efficient, resulted in higher observational learning, and resulted in better maintenance when teaching a variety of expressive skills. The experimenters utilized a parallel treatment design, and the results indicated that both instructional formats were equally effective, there were mixed results in terms of maintenance and efficiency, and group instruction resulted in observational learning.

The unpacking effect in allocations of responsibility for group tasks

Individuals tend to overestimate their relative contributions to collaborative endeavors. Thus, the sum of group members’ estimates of the percentage they each contributed to a joint task typically exceeds the logically allowable 100%. We suggest that this tendency stems partly from individuals’ inclination to regard their fellow group members as a collective rather than as individuals, and that leading people to think about their collaborators as individuals should therefore reduce the perceived relative magnitude of their own contributions. Consistent with this thesis, four experiments demonstrate that people’s tendency to claim more than their fair share of the credit for a group task is attenuated when they “unpack” their collaborators, conceptualizing them as separate individuals, rather than as “the rest of the group.”
