Using behavior contracts to improve behavior of children and adolescents in multiple settings

Research has shown that behavior contracts, a form of contingency management, can promote a wide range of behavior changes for individuals in varied populations; however, relatively few studies have been conducted in nonacademic settings. In the context of two service projects, we evaluated the extent to which behavior contracts improved problem behavior for 11 children and adolescents in residential treatment facilities and foster homes using nonconcurrent multiple baseline across participants’ designs with three or more tiers and supplemental statistical analysis for each tier. Practitioners in each setting implemented individualized behavior contracts for 5 to 59 weeks. Results show that behavior improved substantially for six participants but was relatively unchanged for the other five participants. We discuss the limitations of this clinically driven study, as well as clinical implications of our mixed findings.     

Wittgenstein on Reading

The section on reading occupies quite a large amount of space in the Philosophical Investigations (PI) and Wittgenstein makes little changes to it in the course of composing the book. This shows that the section on reading is important. This paper analyzes Wittgenstein’s treatment of the philosophical problem of reading in detail. It shows that Wittgenstein rejects six philosophical ideas about what reading is and employs three different methods. This paper also shows that the section on reading is not only important for grasping Wittgenstein’s discussion on understanding, but also for comprehending the whole of PI.     

Conscious intention and human action: Review of the rise and fall of the readiness potential and Libet’s clock

Is consciousness—the subjective awareness of the sensations, perceptions, beliefs, desires, and intentions of mental life—a genuine cause of human action or a mere impotent epiphenomenon accompanying the brain’s physical activity but utterly incapable of making anything actually happen? This article will review the history and current status of experiments and commentary related to Libet’s influential paper (Brain 106:623–664, 1983) whose conclusion “that cerebral initiation even of a spontaneous voluntary act …can and usually does begin unconsciously” has had a huge effect on debate about the efficacy of conscious intentions. Early (up to 2008) and more recent (2008 on) experiments replicating and criticizing Libet’s conclusions and especially his methods will be discussed, focusing especially on recent observations that the readiness potential (RP) may only be an “artifact of averaging” and that, when intention is measured using “tone probes,” the onset of intention is found much earlier and often before the onset of the RP. Based on these findings, Libet’s methodology was flawed and his results are no longer valid reasons for rejecting Fodor’s “good old commonsense belief/desire psychology” that “my wanting is causally responsible for my reaching.”.     

母亲负性情绪与儿童外化问题行为的关系：家庭嘈杂度的调节作用

摘 要 对251名学前儿童及母亲进行一年的追踪来考察母亲负性情绪与学前儿童外化问题之间的关系及这一关系是否受到家庭嘈杂度的影响。结果: (1) T1儿童外化问题能正向预测T2母亲负性情绪,而T1母亲负性情绪对T2儿童外化问题的预测不显著;(2)与低嘈杂家庭相比,高嘈杂家庭中儿童外化问题对母亲负性情绪的预测作用更强,且儿童外化问题也更为稳定。结论：母亲负性情绪与儿童外化问题的关系主要表现为儿童效应,且这一效应受到家庭环境的调节。     

Differences in mathematical reasoning between typically achieving and gifted children

Mathematical giftedness refers to mastery in a specific mathematical domain at an earlier than expected age. The present study examined which cognitive processes accounted for differences in mathematical reasoning between gifted children (MRG) and their typically achieving peers (TA). Naming speed, phonological awareness, short-term memory, executive functioning, and working memory were examined in 51 children aged approximately 7 years. A series of stepwise regression models, using a contrast variable to capture differences in mathematical reasoning between MRG and TA children, were created to examine which cognitive domains accounted for differences in mathematical reasoning. Short-term memory (r²?=?.08) and visual-spatial working memory (r²?=?.39) emerged as the only cognitive predictors within a model that included gender, age, and fluid intelligence. This model captured all of the variance distinguishing mathematics reasoning between MRG and TA children, explaining an overall contribution of 70% of the variance in mathematical reasoning.     

Does Problem Focused Coping Buffer the Effects of Trait Anxiety on Depressive Symptoms of Chronic Urticaria Patients?

The present study examined the moderating role of problem-focused coping in trait anxiety—depressive symptoms' relationship in patients with chronic urticaria (CU). Eighty-eight CU patients, who applied to an outpatient clinic of Clinical Immunology and Allergic Diseases, filled out a questionnaire set including State-Trait Anxiety Inventory, Ways of Coping Inventory, and Beck Depression Inventory. The results suggested that CU patients high on trait anxiety reported more depressive symptoms, and the ones using more problem-focused coping (PFC) strategies reported less depressive symptoms. Also, PFC strategies moderated trait anxiety-depressive symptoms relation. Accordingly, PFC strategies did not lead to any significant difference in CU patients who were low on trait anxiety in terms of the level of depressive symptoms. However, CU patients with high trait anxiety experienced significantly less depressive symptoms if they used more PFC strategies. The findings were discussed in the light of the relevant literature.     

Manipulating parameters of reinforcement to reduce problem behavior without extinction

Differential reinforcement of alternative behavior (DRA) most often includes extinction as a treatment component. However, extinction is not always feasible and it can be counter‐therapeutic if implemented without optimal treatment integrity. Researchers have successfully implemented DRA without extinction by manipulating various parameters of reinforcement such that alternative behavior is favored. We extended previous research by assessing three participants' sensitivities to quality, magnitude, and immediacy using arbitrary responses and reinforcers that maintain problem behavior. The results were used to implement an intervention for problem behavior using DRA without extinction. Our findings indicate that arbitrary responses can be used to identify individual and relative sensitivity to parameters of reinforcement for reinforcers that maintain problem behavior. Treatment was effective for all participants when we manipulated parameters of reinforcement to which they were most sensitive, and, for two participants, the treatment was less effective when we manipulated parameters to which they were least sensitive.     

Teaching children with autism to explain how: A case for problem solving?

Few studies have applied Skinner's (1953) conceptualization of problem solving to teach socially significant behaviors to individuals with developmental disabilities. The current study used a multiple probe design across behavior (sets) to evaluate the effects of problem‐solving strategy training (PSST) on the target behavior of explaining how to complete familiar activities. During baseline, none of the three participants with autism spectrum disorder (ASD) could respond to the problems presented to them (i.e., explain how to do the activities). Tact training of the actions in each activity alone was ineffective; however, all participants demonstrated independent explaining‐how following PSST. Further, following PSST with Set 1, tact training alone was sufficient for at least one scenario in sets 2 and 3 for all 3 participants. Results have implications for generative responding for individuals with ASD and further the discussion regarding the role of problem solving in complex verbal behavior.     

Retrospective analysis of changes in response topographies of escape‐maintained aggressive behavior during functional analyses

We observed changes in the rates of response topographies during the demand condition of functional analyses for participants who demonstrated problem behavior maintained by escape. Over the course of the functional analysis for each participant, the number of topographies decreased from the first to the last session. Additionally, after the first session of the demand condition the rate of responding for one topography increased or remained at high levels while the rates of all other topographies decreased. The implications of these results when conducting functional analysis are discussed.     

Predictive validity and efficiency of ongoing visual‐inspection criteria for interpreting functional analyses

Prior research has evaluated the reliability and validity of structured criteria for visually inspecting functional‐analysis (FA) results on a post‐hoc basis, after completion of the FA (i.e., post‐hoc visual inspection [PHVI]; e.g., Hagopian et al., 1997). However, most behavior analysts inspect FAs using ongoing visual inspection (OVI) as the FA is implemented, and the validity of applying structured criteria during OVI remains unknown. In this investigation, we evaluated the predictive validity and efficiency of applying structured criteria on an ongoing basis by comparing the interim interpretations produced through OVI with (a) the final interpretations produced by PHVI, (b) the authors’ post‐hoc interpretations (PHAI) reported in the research studies, and (c) the consensus interpretations of these two post‐hoc analyses. Ongoing visual inspection predicted the results of PHVI and the consensus interpretations with a very high degree of accuracy, and PHAI with a reasonably high degree of accuracy. Furthermore, the PHVI and PHAI results involved 32 FA sessions, on average, whereas the OVI required only 19 FA sessions to accurately identify the function(s) of destructive behavior (i.e., a 41% increase in efficiency). We discuss these findings relative to other methods designed to increase the accuracy and efficiency of FAs.
