FUNCTIONAL ANALYSIS AND TREATMENT OF INAPPROPRIATE VERBAL BEHAVIOR

The present study examined the possible function of inappropriate verbal behavior of an adult man who had been diagnosed with both mental retardation and psychosis. Results of a functional analysis indicated that inappropriate verbal utterances were maintained by attention. An intervention consisting of the differential reinforcement of appropriate verbal behavior effectively reduced the inappropriate behavior.     

The direct support workforce in community supports to individuals with developmental disabilities: issues, implications, and promising practices

Difficulties in finding, keeping, and ensuring the competence of the direct support workforce in community developmental disability services has long been a challenge for individuals, families, providers, and policy makers. Direct support staff recruitment, retention, and competence are widely reported as one of the most significant barriers to the sustainability, growth, and quality of community services for people with developmental disabilities (ANCOR [2001] State of the states report. Alexandria, VA: ANCOR; Colorado Department of Human Services, [2000] Response to Footnote 106 of the FY 2001 appropriations long bill: Capacity of the community services systems for persons with developmental disabilities in Colorado; Hewitt [2000] Dynamics of the workforce crisis. Presentation at the NASDDDS Fall meeting. Alexandria, VA). While long in existence, these challenges are ones of growing concern because the number of people demanding community services is increasing and the population of people from which to recruit workers is declining (Office of the Assistant Secretary for Planning and Evaluation [2006] The supply of direct support professionals serving individuals with intellectual disabilities and other developmental disabilities: Report to Congress. Washington, DC: Office of Disability, Aging and Long-Term Care Policy, ASPE, U.S. Department of Health and Human Services). As the service system moves towards consumer direction, managed care, and more noncategorical service delivery systems, the difficulties of providing for an adequate and well-prepared workforce to support people with developmental disabilities becomes more complex and multifaceted. The solutions to those challenges are also more complex. This article reviews the literature regarding the complexity of the direct support workforce crisis, the effects of this crisis on various stakeholder groups, promising practices designed to address the challenges, and the related practice and policy implications.     

The shape of threat: simple geometric forms evoke rapid and sustained capture of attention

Previous work has indicated that simple geometric shapes underlying facial expressions are capable of conveying emotional meaning. Specifically, a series of studies found that a simple shape, a downward-pointing "V," which is similar to the geometric configuration of the face in angry expressions, is perceived as threatening. A parallel line of research has determined that threatening stimuli more readily capture attention. In five experiments, the authors sought to determine whether this preferential processing was also present for the simple geometric form of a downward-pointing "V." Using a visual search paradigm, across these experiments the authors found that, when embedded in a field of other shapes, downward-pointing V's were detected faster and, in some cases, more accurately than identical shapes pointing upward. These findings indicate that the meaning of threat can be conveyed rapidly with minimal stimulus detail. In addition, in some cases, during trials of homogeneous fields of stimuli, fields of downward-pointing V's led to slower response times, suggesting that this shape's ability to capture attention may also extend to difficulty in disengaging attention as well.     

Avoidance of Counseling: Psychological Factors That Inhibit Seeking Help

How do counselors reach out to individuals who are reluctant to seek counseling services? To answer this question, the authors examined the research on the psychological help‐seeking barriers from counseling, clinical and social psychology, as well as social work and psychiatry. Specific avoidance factors that have been identified in the mental health literature; important variations in the setting, problem type, demographics, and cultural characteristics that can influence the degree to which avoidance factors affect professional help‐seeking decisions; and suggestions for overcoming these avoidance factors are discussed.     

Left-hemisphere activation is associated with enhanced vocal pitch error detection in musicians with absolute pitch

The ability to process auditory feedback for vocal pitch control is crucial during speaking and singing. Previous studies have suggested that musicians with absolute pitch (AP) develop specialized left-hemisphere mechanisms for pitch processing. The present study adopted an auditory feedback pitch perturbation paradigm combined with ERP recordings to test the hypothesis whether the neural mechanisms of the left-hemisphere enhance vocal pitch error detection and control in AP musicians compared with relative pitch (RP) musicians and non-musicians (NM). Results showed a stronger N1 response to pitch-shifted voice feedback in the right-hemisphere for both AP and RP musicians compared with the NM group. However, the left-hemisphere P2 component activation was greater in AP and RP musicians compared with NMs and also for the AP compared with RP musicians. The NM group was slower in generating compensatory vocal reactions to feedback pitch perturbation compared with musicians, and they failed to re-adjust their vocal pitch after the feedback perturbation was removed. These findings suggest that in the earlier stages of cortical neural processing, the right hemisphere is more active in musicians for detecting pitch changes in voice feedback. In the later stages, the left-hemisphere is more active during the processing of auditory feedback for vocal motor control and seems to involve specialized mechanisms that facilitate pitch processing in the AP compared with RP musicians. These findings indicate that the left hemisphere mechanisms of AP ability are associated with improved auditory feedback pitch processing during vocal pitch control in tasks such as speaking or singing.     

Blur detection is unaffected by cognitive load

Blur detection is affected by retinal eccentricity, but is it also affected by attentional resources? Research showing effects of selective attention on acuity and contrast sensitivity suggests that allocating attention should increase blur detection. However, research showing that blur affects selection of saccade targets suggests that blur detection may be pre-attentive. To investigate this question, we carried out experiments in which viewers detected blur in real-world scenes under varying levels of cognitive load manipulated by the N-back task. We used adaptive threshold estimation to measure blur detection thresholds at 0°, 3°, 6°, and 9° eccentricity. Participants carried out blur detection as a single task, a single task with to-be-ignored letters, or an N-back task with four levels of cognitive load (0, 1, 2, or 3-back). In Experiment 1, blur was presented gaze-contingently for occasional single eye fixations while participants viewed scenes in preparation for an easy picture recognition memory task, and the N-back stimuli were presented auditorily. The results for three participants showed a large effect of retinal eccentricity on blur thresholds, significant effects of N-back level on N-back performance, scene recognition memory, and gaze dispersion, but no effect of N-back level on blur thresholds. In Experiment 2, we replicated Experiment 1 but presented the images tachistoscopically for 200 ms (half with, half without blur), to determine whether gaze-contingent blur presentation in Experiment 1 had produced attentional capture by blur onset during a fixation, thus eliminating any effect of cognitive load on blur detection. The results with three new participants replicated those of Experiment 1, indicating that the use of gaze-contingent blur presentation could not explain the lack of effect of cognitive load on blur detection. Thus, apparently blur detection in real-world scene images is unaffected by attentional resources, as manipulated by the cognitive load produced by the N-back task.     

The relationship between family‐of‐origin experiences and sexual satisfaction in married couples

This study examined the relationship between perceptions of family‐of‐origin experiences, sexual satisfaction and marital quality. The sample consisted of 3953 married couples who responded to the relationship evaluation. The results showed that more positive overall family‐of‐origin experiences and parent–child relationships were related to higher sexual satisfaction. Overall, family‐of‐origin experiences and parent–child relationships were predictive of higher sexual satisfaction; however, that relationship was significantly mediated by marital quality. There was a strong positive relationship between marital quality and sexual satisfaction. No major gender differences emerged from the findings. The results suggest that family‐of‐origin experiences play a key role in the sexual satisfaction of married couples, especially when mediated by marital quality, and should be considered in treatment, education and research.     

Coping style and memory specificity in adolescents and adults with histories of child sexual abuse

Individuals with histories of childhood trauma may adopt a nonspecific memory retrieval strategy to avoid unpleasant and intrusive memories. In a sample of 93 adolescents and adults with or without histories of child sexual abuse (CSA), we tested the hypothesis that nonspecific memory retrieval is related to an individual's general tendency to use avoidant (i.e., distancing) coping as a personal problem-solving or coping strategy, especially in victims of CSA. We also examined age differences and other individual differences (e.g., trauma-related psychopathology) as predictors of nonspecific memories. Distancing coping was significantly associated with less specific autobiographical memory. Younger age, lower vocabulary scores, and non-CSA childhood maltreatment (i.e., physical and emotional abuse) also uniquely predicted less autobiographical memory specificity, whereas trauma-related psychopathology was associated with more specific memory. Implications for the development of autobiographical memory retrieval in the context of coping with childhood maltreatment are discussed.
