Seek,and ye shall find: Differences between spontaneous and voluntary analogical retrieval

The present study tackles two overlooked aspects of analogical retrieval: (a) whether argumentation activities elicit a spontaneous search for analogical sources, and (b) whether strategic search can relax the superficial bias typically obtained in experimental studies of analogical retrieval. In Experiment 1, participants had to generate arguments for a target situation under three conditions: without indication to use analogies, with indication to use analogies, and with indication to search for sources within domains provided by the experimenters. Results showed that while voluntary search yields analogical retrievals reliably, the argumentation activity seldom elicits spontaneous remindings. A second set of results demonstrated that the superficial bias can be strategically relaxed, leading to a majority of distant retrievals. Experiment 2 replicated this result with the instruction to search within domains different from that of the target, and without providing a list of specific domains. The theoretical and educational implications of these findings are discussed.     

Comparing structured mix and random rotation procedures to teach receptive labeling to children with autism

We compared two procedures using an alternating treatments design to teach receptive labeling to children with autism. The structured mix procedure followed seven steps entailing mass trials, intermixing, and random rotation. In the random rotation procedure, we trained all stimuli from the start. Study 1 included four children with a repertoire of four to 50 receptive labels and who primarily communicated with an alternative communication device. Results showed that the two conditions were comparable for one participant, structured mix was effective and random rotation was not effective for one participant, and that both conditions were ineffective for two participants. Study 2 included five children with over 200 receptive labels in their repertoire and with vocal speech as the primary form of communication. Four participants acquired the labels in both procedures, but random rotation was more effective. Results indicate that structured mix may be more effective for participants with a limited language repertoire and random rotation is more effective for participants with a larger language repertoire.     

Resurgence following differential reinforcement of alternative behavior implemented with and without extinction

In the clinic, differential reinforcement of alternative behavior (DRA) often involves programming extinction for destructive behavior while reinforcing an alternative form of communication (e.g., a functional communication response); however, implementing extinction can be unsafe or impractical under some circumstances. Quantitative theories of resurgence (i.e., Behavioral Momentum Theory and Resurgence as Choice) predict differences in the efficacy of treatments that do and do not involve extinction of target responding when reinforcement conditions maintaining alternative responding worsen. We tested these predictions by examining resurgence following two DRA conditions in which we equated rates of reinforcement. In DRA without extinction, target and alternative behavior produced reinforcement. In DRA with extinction plus noncontingent reinforcement, only alternative behavior produced reinforcement. We conducted this study in a reverse-translation sequence, first with participants who engaged in destructive behavior (Experiment 1) and then in a laboratory setting with rats (Experiment 2). Across both experiments, we observed proportionally lower levels of target responding during and following the DRA condition that arranged extinction for the target response. However, levels of resurgence were similar following both arrangements.     

Use of a paired-stimulus demand analysis to evaluate demands for inclusion in functional analyses

Clinicians regularly use both indirect and direct assessments to identify preferred stimuli to include in control conditions and positive reinforcement test conditions in a functional analysis (FA). However, clinicians often rely on indirect assessment alone (e.g., caregiver report) to identify aversive stimuli to include in negative reinforcement test conditions. In this study, we evaluate a paired-stimulus demand analysis and validate assessment results via FA. Results indicate that, for all 4 participants, the demands selected least often evoked higher rates of destructive behavior than more frequently selected demands. We identified an escape function for all 4 participants in the escape–least selected (LS) condition (true positive finding) and for only 1 participant in the escape–most selected (MS) condition (false negative finding for 3 of 4 participants). These results support the utility of empirically deriving stimuli for inclusion in the negative reinforcement test condition of an FA to decrease the likelihood of false negative findings.     

Forensic neuropsychiatric evaluation of a personal injury case

Civil litigation involving the forensic neuropsychiatric evaluation of a personal injury case requires an assessment of damages and causation. The expert witness is obliged to integrate data from three critical sources of information: the review of records; the results of neuropsychological testing; and the findings from the clinical examination. In civil litigation involving a personal injury claim, the expert witness can be expected to address causation and prognosis of any neuropsychiatric damages. We discuss the undertaking of a forensic neuropsychiatric evaluation, psychiatric disorders often encountered in personal injury litigation, provide case vignettes and describe a number of special types of forensic neuropsychiatric evaluations, for example, Workers' Compensation, VA Disability and Social Security Disability.     

Examination of relative reinforcement effects of stimuli identified through pretreatment and daily brief preference assessments.

Several brief preference assessments have recently been developed to identify reinforcers for individuals with developmental disabilities. One purported advantage of brief assessments is that they can be administered frequently, thus accommodating shifts in preference and presumably enhancing reinforcement effects. In this study, we initially conducted lengthy paired‐choice preference assessments and identified a hierarchy of preferred items for 5 individuals with developmental disabilities. Subsequently, brief multiple‐stimulus‐without‐replacement assessments using the same items were completed each day prior to work sessions. On days when results of the daily brief assessment differed from the one‐time lengthy assessment, the relative reinforcing effects of the top items from each assessment were compared in a concurrent‐schedule arrangement. The results revealed that when the two assessments differed, participants generally allocated more responses to the task associated with the daily top‐ranked item.     

Menstrual symptoms and up-down vectors

Multiple studies considered the somatic symptom correlates of up-down asymmetries in women. In four samples, involving a total of 81 women, menstrual symptoms were significantly linked with the up-down distortion of the space surrounding self. In addition, there were borderline relationships between menstrual symptoms and other indices of up-down asymmetry. The findings suggested a possible link between menstrual symptoms and concerns about possessing versus not possessing power. Over-all, the results support previous studies indicating that spatial sets reflect important attitudes or conflicts that seem to play a role in somatic symptomatology. However, they point up the importance of considering sex differences.     

Subjective Expected Utility,Locus of Control,and Behavior1

Although a fundamental assumption of behavior decision theory is that individuals must generally believe they can control their fate if their behavior is to be influenced by subjective expected utility (SEU), the hypothesis that the positive relationship between SEU and behavior is stronger for those with internal locus of control had not been directly tested. That hypothesis was assessed in two separate longitudinal studies of adolescents. The behavior studied in one sample was the initiation of cigarette smoking, and in the other it was the onset of drinking alcohol. The hypothesis received weak support in both studies.
