Head Start Children at Third Grade: Preliminary Special Education Identification and Placement of Children with Emotional, Learning, and Related Disabilities

Although children in Head Start are at risk for emotional or behavioral problems, little is known about their later need for special education. There is evidence that children at risk for emotional disturbance are underidentified or misidentified in other special education categories. We examined special education identification rates for Head Start children at risk for emotional disturbance, learning disabilities, speech or language impairments, and mental retardation as they complete third grade. Two cohorts of 4136 children across 30 sites were followed as part of a larger study on transition. Diagnosis of each child as being at risk for emotional disturbance or related disabilities was made using clinical cut-offs on teacher ratings and individual testing completed in the spring of third grade. Special education eligibility of these children was determined from school records. Only 31.8% of children considered to be at risk, based on research diagnostic criteria, were actually identified by the schools, and fewer than 6% of children at risk for ED were identified in the school category of ED. Comparisons were made between school-identified and nonidentified children in gender, ethnicity, and school variables; and findings were discussed in relation to underidentification or misidentification of children with emotional disturbance.     

Professional and Provider Perspectives on Family Involvement in Therapeutic Foster Care

Therapeutic foster care (TFC) offers a promising community-based treatment option for children with serious emotional and behavioral disorders in the child welfare system. Family involvement is believed to contribute to achieving the goal of family reunification in TFC, but there has been little attention to family involvement in TFC. I present findings of a qualitative study of child welfare professionals' and TFC providers' perspectives on family involvement. Respondents' views of parent-child contact, parent-professional communication and information sharing, and family involvement in decision making were examined. Values and attitudes toward family involvement, practices related to family involvement, barriers to involvement, and strategies to promote involvement emerged as themes. Professionals in this study believed in the value of family involvement, but there were challenges at the organizational level and related to some TFC providers' lack of training to work with families.

Brain asymmetry and autonomic conditioning: Sensitization control

In the present experiment we report effects of cerebral asymmetry, or laterality, during classical conditioning to facial emotional stimuli. Twenty-five female subjects were presented with slides of a happy face in one visual half-field (VHF), and simultaneously a slide of an angry face in the other VHF, followed by shock as the unconditioned stimulus (UCS). To control for effects of sensitization, a new stimulus, never associated with the UCS, was introduced in the extinction phase. Dependent measures were phasic heart rate responses (HR) and skin conductance responses (SCR). The HR results showed a significant right hemisphere effect for the CS-UCS association, that was not attributable to UCS sensitization. No significant effects were found for the SCRs. The basic HR finding was a right hemisphere superiority for learning of a conditioned association.     

A jackknife test of homogeneity of variance with paired replicates data

A nonparametric test of dispersion with paired replicates data is described which involves jackknifing logarithmic transformations of the ratio of variance estimates for the pre- and post-treatment populations. Results from a Monte Carlo simulation show that the test performs well underH _o and has good power properties. Examples are given of applying the procedure on psychiatric data.A referee called our attention to valuable references which related to our work, and he suggested the inclusion of competing jackknife procedures into our studies.     

Context specificity of operant discriminative performance in pigeons: II. Necessary and sufficient conditions

Six experiments were performed to explore the necessary and sufficient conditions for producing context specificity of discriminative operant performance in pigeons. In Experiment 1, pigeons learned a successive discrimination (red S+/blue S−) in two chambers that had a particular odor present and between which they were frequently switched. The birds subsequently learned the reversal (blue S+/ red S−) in one of these chambers with a different odor present. When switched to the alternative chamber, although the odor and the reinforcement contingency were still appropriate to the reversal, performance appropriate to the original discrimination recurred in subjects for which the houselights were on during training and testing but not for those for which the houselights were off. This indicated the importance of visual contextual cues in producing context specificity. Experiment 2 showed that the frequent switching between boxes in initial training was of no consequence, presumably because the apparatus cues were highly salient to the subjects. Experiment 3 showed significantly less context specificity when odor cues were omitted. Experiment 4 showed that simply using a different reinforced stimulus in each phase of training was ineffective in producing context specificity. Experiment 5 showed that the generalization test procedure used in Experiment 4 was sensitive to context specificity when discrimination-reversal training was used with different odors in the two training phases. Experiment 6 replicated the results of Experiment 4, but then showed that when different odors accompanied the two training phases, context specificity was obtained with the single-stimulus paradigm. Thus in both single-stimulus and discrimination-reversal paradigms, redundant odor cues potentiated learning about apparatus cues.     

听力正常人与聋人短时记忆的比较研究

以视觉系列呈现,自由回忆的方法比较了听力正常人与聋人对分别被强化的厂类相似性汉语字表的短时记忆获得量。从总的平均获得量来看,两组结果没有显著差异,而从每一编码维量在短时记忆的加工过程中的作用来看,两组被试都显示出了形、义两维编码维量的作用最强,而音码的作用相对比较弱。两组被试也都显示出了明显的系列位置效应,但聋人组的次级记忆容量明显地低于听力正常组,而初级记忆容量两组没有显著差异。并对可能的机制进行了讨论。     

频率差异假设和长时记忆的视优效应

本文包括长时记忆视优效应的三项实验。实验一使用汉语为学习材料,北京人与广东人为被试;实验二使用英语为学习材料、美国人与中国人为被试;实验三使用日语为学习材料、日本人为被试。三项实验都有视觉、听觉两种呈现方式。三项实验的结果都有利于证明频率差异假设,即如果在书面言语中经验某字词的频率高于在口语中经验该字词的频率,则该字词的视觉呈现优于听觉呈现。     

Confirmation of linear system theory prediction: Changes in Herrnstein's k as a function of changes in reinforcer magnitude

Eight human subjects pressed a lever on a range of variable-interval schedules for 0.25¢ to 35.0¢ per reinforcement. Herrnstein's hyperbola described seven of the eight subjects' response-rate data well. For all subjects, the y-asymptote of the hyperbola increased with increasing reinforcer magnitude and its reciprocal was a linear function of the reciprocal of reinforcer magnitude. These results confirm predictions made by linear system theory; they contradict formal properties of Herrnstein's account and of six other mathematical accounts of single-alternative responding.     

The crying boss: Activating “human resources” through sensitivity training in 1970s Sweden

This article examines the introduction of “sensitivity training” to 1970s Swedish work life. Drawing upon a range of empirical materials, I explore the politics that were involved in the process of translating and adapting this group dynamic method to the Swedish context and consider how its proponents argued for its value. By approaching sensitivity training as an attempt to govern, shape, and regulate both human beings and the work organizations of which they were a part, I argue that sensitivity training presents an unexpectedly early example of a governing rationality that has elsewhere been described and theorized as “neoliberal.” The fact that sensitivity training was established in Swedish work life already in the early 1970s thus challenges the historiography of neoliberal modes of government, which have elsewhere been associated with a neoliberal shift in state policies occurring in the 1980s and 1990s. The article demonstrates how emotionally liberating practices in the late 1960s and early 1970s were embraced by some of the most politically influential actors in contemporary Swedish society, such as the corporate sector and the trade unions. As blue-collar trade unions and social democrats voiced increasingly far-reaching demands concerning workplace democracy and improved workplace conditions, advocates of sensitivity training presented their method as crucial to the process of “democratizing” and “humanizing” Swedish work life. Intimately associated with the new therapies of humanistic psychology, sensitivity training was used within the corporate sector to foster a more emotional and authentic leadership style that would embrace the values of emotional awareness, self-expression, and self-actualization. The crying boss emerged in this context as a key figure in the project of creating a “democratic” and psychologically satisfying organization. Yet, sensitivity training was also described as a means for companies to make better use of what was now asserted as their most important economic asset: the human being. From the outset, the idealistic vision of an emotionally liberated, democratic workplace was thus entangled with a specific kind of economic rationality, in which the emotionally liberated, self-actualizing individual emerged as a capital or asset that would be better utilized if the organization allowed—even encouraged—employees to engage in their own well-being and self-optimization.
