Response interruption and redirection for vocal stereotypy in children with autism: a systematic replication 总被引:1,自引:0,他引:1
Cassella MD Sidener TM Sidener DW Progar PR 《Journal of applied behavior analysis》2011,44(1):169-173
This study systematically replicated and extended previous research on response interruption and redirection (RIRD) by assessing instructed responses of a different topography than the target behavior, percentage of session spent in treatment, generalization of behavior reduction, and social validity of the intervention. Results showed that RIRD produced substantial decreases in vocal stereotypy. Limitations of this study were that behavior reduction did not generalize to novel settings or with novel instructors and that appropriate vocalizations did not improve. 相似文献

The cognitive effort explanations of contextual interference (CI) and implicit motor learning represent a paradox in which cognitive involvement is seen to be advantageous or disadvantageous for learning. The authors aimed to resolve this paradox by measuring cognitive effort and working memory dependence during low and high CI practice on two Australian Rules Football tasks (kicking and handball). Measures of cognitive effort included: kicking and handball outcome performance during acquisition and during a test of retention, performance on a probe reaction time task during a sample of acquisition trials, and self-reported levels of cognitive effort. Measures of implicit and explicit learning included kicking and handball performance during a secondary task transfer, and self-report verbal protocols (number of verbal rules and hypotheses reported). The results suggest that high CI may cause an implicit mode of learning, perhaps due to the interference caused by task switching. However, these findings are restricted to the more complex of the 2 tasks (kicking). 相似文献

Although the Internet is a beneficial tool, some youth are at risk for being victimized by Internet predators. School counselors are in a unique position to assist in efforts to prevent online victimizations because of their continual interaction with students, parents, and other school faculty. This article provides school counselors with information about youth Internet use; risk factors associated with online victimizations; and recommendations to assist youth, parents, and families in improving Internet safety practices. 相似文献

This study examined the interactions of stimulus type (high‐ vs. low‐tech) and magnitude (duration of access) on preference and reinforcer efficacy. Two preference assessments were conducted to identify highly preferred high‐tech and low‐tech items for each participant. A subsequent assessment examined preference for those items when provided at 30‐s and 600‐s durations. We then evaluated reinforcer efficacy for those same items when provided for a range of durations using progressive‐ratio schedules. Results suggested item type and access duration interacted to influence preference and reinforcer efficacy. Participants preferred high‐tech items at longer durations of access and engaged in more responding when the high‐tech item was provided for long durations, but these patterns were reversed for the low‐tech item. In addition, participants engaged in less responding when the high‐tech item was provided for short durations and when the low‐tech item was provided for long durations. 相似文献

A new suicide-specific diagnostic entity, acute suicidal affective disturbance (ASAD), was recently proposed to fill a void in the nomenclature. Although several studies have examined the reliability, validity, and potential clinical utility of ASAD, no studies have examined personality indicators of ASAD. This study sought to examine the association between personality and psychopathology factors, as assessed by the Minnesota Multiphasic Personality Inventory–2–Revised Form (MMPI–2–RF), and constructs that comprise ASAD in a sample of 554 psychiatric outpatients who completed all measures prior to their intake appointments. A smaller subset of patients (N = 58) also completed a measure designed to assess lifetime ASAD symptoms. Results indicated that ASAD symptoms were associated with traits characterized by emotional turmoil and atypical cognitive processes. Further, suicide-related criteria that comprise ASAD were related to low positive emotionality and hopelessness, whereas the overarousal criteria were associated with somatic symptoms and an inability to tolerate frustration and stress. These findings expand on previous research that examines the convergent and discriminant validity of ASAD and could inform clinical treatment by providing insight into personality traits that might be associated with acute suicide risk. 相似文献

Measures of walking such as the timed 25-ft walk test (T25FWT) may not be able to detect subtle impairment in lower limb function among people with multiple sclerosis (MS). We examined bipedal hopping to determine to what extent people with mild (Expanded Disease Severity Scale ≤ 3.5) MS (n = 13) would differ compared to age-, gender-, and education-matched controls (n = 9) and elderly participants (n = 13; ≥ 70 years old). We estimated lower limb power (e.g., hop length, velocity), consistency (e.g., variability of hop length, time), and symmetry (ratio of left to right foot). Participants completed the T25FWT and, after a rest, they then hopped using both feet 4 times along the walkway. We found that although all groups scored below the 6 -s cutoff for T25FWT, the elderly group had significantly shorter hop lengths, more variability, and more asymmetry than the controls. The results of the MS group were not significantly different from the elderly or controls in most measures and most of their values fell between the control and elderly groups. Hop length, but not measures of walking predicted Expanded Disease Severity Scale score (R2 = .38, p = .02). Bipedal hopping is a potentially useful measure of lower limb neuromuscular performance. 相似文献

Evidence suggests that live sporting events may lead fans to engage in criminal behaviors. The current study examined the relationship between criminal behavior and college football game days. Archival data of criminal offenses were collected from Southeastern Conference member institution police departments to analyze reported criminal offenses during the regular season. Multilevel linear models revealed an increase in criminal behavior. A factorial ANOVA indicated an interaction of team rankings and game outcome was related to specific types of criminal behavior in the host city (F (1, 9142) = 20.07, p < .001). Results provide insight to more effectively allocate resources. 相似文献

Cohabiting family structures are becoming increasingly prevalent in the United States but are less stable than married family unions. In this longitudinal study we examine the change in psychosocial adjustment of adolescents when a non-biologically related male cohabiting partner (MCP) transitions out of the family home. Of particular interest, the role of maternal and MCP depressive symptoms was examined as a moderator. At wave 1, the sample was comprised of 111 low-income urban Black families, consisting of an adolescent (42.3 % male; Mage = 13), a biological mother, and a non-biologically-related male cohabiting partner (MCP). Wave 2 and 3 assessments occurred over the course of the subsequent 29 months, with 38 % of MCPs transitioning out of the home. We used latent growth curve modeling to characterize trajectories of youth internalizing and externalizing symptom change across the 3 waves. Both maternal and MCP depressive symptoms interacted with whether a transition occurred, consistent with the notion that adolescent problem behaviors are shaped by the dynamic interplay of individual- and family-characteristics. 相似文献
