Functional assessment, collaboration, and evidence-based treatment: Analysis of a team approach for addressing challenging behaviors in young children

This study examined the effects of functional assessment and positive behavior support on classroom behaviors of young children. An experimental program, entitled FACET, was implemented by school-based teams in pre-kindergarten through first-grade classrooms. Observations of child behaviors and classroom variables were compared between experimental and control classrooms. Results indicate that children in FACET classrooms made significant gains from baseline to post-intervention and exhibited a higher occurrence of positive behaviors and fewer negative behaviors compared to control children. Behavior gains were positively correlated with the level of treatment fidelity. These findings support the effectiveness of an intervention that incorporates functional assessment, collaboration, and evidence-based treatment with young children who exhibit challenging behaviors.     

Functional reduction and emergence in the physical sciences

Kim’s model of ‘functional reduction’ of properties is shown to fail in a class of cases from physics involving properties at different spatial levels. The diagnosis of this failure leads to a non-reductive account of the relation of micro and macro properties.

An experimental analysis of hypochondriasis

Hypochondriasis (HC) involves preoccupation with fears of having a serious medical illness based on the misinterpretation of benign bodily perturbations. Individuals with HC also perform behaviors such as checking and reassurance-seeking presumably to reduce health-related fears. Experimental behavioral analyses of HC symptoms, however, are lacking. In the present study, 27 patients with HC were exposed to personally relevant health-related stimuli under one of two conditions: (a) subsequently performing safety-seeking behaviors (e.g., checking) (n=14) or (b) subsequently being instructed not to perform such behaviors (n=13). In both groups, subjective anxiety and urges to perform safety behaviors were monitored for 1h. Results indicated that exposure to the personally relevant health trigger provoked anxiety and urges to perform safety behaviors. For patients who performed such behaviors, these feelings were reduced. For patients who did not, a more gradual reduction of anxiety and urges was observed. Findings are discussed in terms of the conceptualization and treatment of HC behavior, and are relevant to HC's possible relationship to panic and obsessive-compulsive disorder.     

How to turn a hawk into a dove and vice versa: Interactions between emotions and goals in a give-some dilemma game

The present study investigated emotional influences on behavior in a one-shot, simultaneous, give-some dilemma game. In accordance with functional perspectives on the role of discrete emotions, we found fear to reduce, and guilt to increase levels of cooperation. Moreover, we showed individual differences in the effect of induced emotional states. Specifically, results indicated that inducing fear reduced cooperation only for individuals with a pro-social value orientation, and that guilt induction increased cooperation only for individuals with a pro-self value orientation. We also established that both social value orientations could be adequately described in terms of differences in chronically accessible goals (as assessed by value-importance ratings). These results, therefore, seem to support our hypothesis that individual differences in the behavioral consequences of induced emotional states are related to variation in chronic accessibility of general goals associated with a particular emotional state.

下腰痛影像诊断的综合效价分析

对61例下腰痛患者的影像学检查资料进行研究,分析各影像学检查方法的效价。结果显示所有患者均进行了3种以上的影像学检查,X线检查费用占总费用的11．67％,脊髓造影占24．67％,CT占14．33％,CTM占7．33％,MRI占42％;常规X线摄片对骨性结构具有较高的分辨率,为进一步影像学检查提供依据。因此,在下腰痛的诊断过程中,必须合理地选择影像学检查方法,以最合理的花费达到正确诊断,节约卫生资源。     

The role of the right posterior parietal cortex in temporal order judgment

Perceived order of two consecutive stimuli may not correspond to the order of their physical onsets. Such a disagreement presumably results from a difference in the speed of stimulus processing toward central decision mechanisms. Since previous evidence suggests that the right posterior parietal cortex (PPC) plays a role in modulating the processing speed of a visual target, we applied single-pulse TMS over the region in 14 normal subjects, while they judged the temporal order of two consecutive visual stimuli. Stimulus-onset-asynchrony (SOA) randomly varied between -100 and 100 ms in 20-ms steps (with a positive SOA when a target appeared on the right hemi-field before the other on the left), and a point of subjective simultaneity was measured for individual subjects. TMS stimulation was time-locked at 50, 100, 150, and 200 ms after the onset of the first stimulus, and results in trials with TMS on right PPC were compared with those in trials without TMS. TMS over the right PPC delayed the detection of a visual target in the contralateral, i.e., left hemi-field by 24 (+/-7 SE) ms and 16 (+/-4 SE) ms, when the stimulation was given at 50 and 100 ms after the first target onset. In contrast, TMS on the left PPC was not effective. These results show that the right PPC is important in a timely detection of a target appearing on the left visual field, especially in competition with another target simultaneously appearing in the opposite field.
