Classwide Teacher Implementation of Self-Regulated Strategy Development for Writing with Students with E/BD in a Residential Facility

One promising intervention to support the writing skills of students with and at risk for emotional and behavioral disorders is self-regulated strategy development (SRSD). The purpose of this study was to extend this line of inquiry to a residential setting with teachers serving as interventionists and determine the effects of the SRSD using the STOP and DARE mnemonic for persuasive writing on the writing performance (Correct Word Sequences, Essay Elements, and Essay Quality), and academic engagement of secondary students. In addition, this study extended this line of inquiry by looking at implementation of the intervention only 2 days per week, a lower treatment intensity than previous research has used to find statistically significant gains in writing. Results of a piecewise hierarchical linear model suggest statistically significant gains were made over the course of the intervention in writing and academic engagement when compared to baseline. In addition, student variables such as writing achievement, externalizing/internalizing behavior patterns, age, and attendance predicted writing and engagement. Results of generalization, fidelity, and social validity also are reported.     

Charter School Enrollment Effects: A Review of Results from Recent Large-Scale Studies

Responding to calls for increased accountability regarding performance of students in public schools and concerns over the capacity of public schools to improve outcomes, school choice has become a mainstream and often controversial issue in public education; it is also a priority of the current federal government administration. Given the mixed evidence of effects on academic performance of charter school enrollment, along with the common perception that charter schools fail to meet the needs of special populations of students—including students with disabilities and English language learners (ELLs)—this study examined the performance of these subgroups across traditional public schools and charter schools. Specifically, we reviewed five recent large-scale studies that assess the impact of charter schools on academic performance paying particular attention to how students with disabilities and students identified as ELLs fare in charter schools relative to their peers served in traditional district schools.     

Illusory-figure lightness: evidence for a two-component theory

Physical darkness gradients were introduced into an illusory-figure pattern which were sufficient to eliminate the illusory lightness effect otherwise seen there. Next, such a gradient was left in place along one edge of that figure while the other edges were returned to physical homogeneity with the surround. Rather surprisingly, the physical gradient still present along the unaltered edge was now overwhelmed by illusory lightness. It is argued that this anomaly suggests that illusory-figure lightness may be composed of two additive components, one of which is figure-ground contrast enhancement and the other of which is contingent upon that first component.     

Shyness–anxiousness and receptive language skills development in Spanish- and English-speaking preschoolers

The present study utilized a short-term longitudinal research design to model the relationship between shyness–anxiousness and receptive language skills. Hypotheses regarding the direction of the causal relationship, mediation, and moderation were evaluated. Subjects included 340 Head Start attendees from primarily English- and Spanish-speaking homes. Results suggest that a unidirectional relationship between shyness–anxiousness and receptive language skills emerges in preschool. Shyness–anxiousness impacted receptive language skills and this relationship was mediated by communication competence. Neither gender nor native language moderated the indirect relationship from shyness–anxiousness to receptive language through communication competence. These results are discussed with respect to elucidating the nature of the bidirectional relationship between shyness–anxiousness and language skills and identifying intervention targets to improve language outcomes for shy–anxious preschoolers.     

Variations in recollection: the effects of complexity on source recognition

Whether recollection is a threshold or signal detection process is highly controversial, and the controversy has centered in part on the shape of receiver operating characteristics (ROCs) and z-transformed ROCs (zROCs). U-shaped zROCs observed in tests thought to rely heavily on recollection, such as source memory tests, have provided evidence in favor of the threshold assumption, but zROCs are not always as U-shaped as threshold theory predicts. Source zROCs have been shown to become more linear when the contribution of familiarity to source discriminations is increased, and this may account for the existing results. However, another way in which source zROCs may become more linear is if the recollection threshold begins to break down and recollection becomes more graded and Gaussian. We tested the "graded recollection" account in the current study. We found that increasing stimulus complexity (i.e., changing from single words to sentences) or increasing source complexity (i.e., changing the sources from audio to videos of speakers) resulted in flatter source zROCs. In addition, conditions expected to reduce recollection (i.e., divided attention and amnesia) had comparable effects on source memory in simple and complex conditions, suggesting that differences between simple and complex conditions were due to differences in the nature of recollection, rather than differences in the utility of familiarity. The results suggest that under conditions of high complexity, recollection can appear more graded, and it can produce curved ROCs. The results have implications for measurement models and for current theories of recognition memory.     

The benefits of empathy: When empathy may sustain cooperation in social dilemmas

Cooperation in social dilemmas is often challenged by negative noise, or unintended errors, such that the actual behavior is less cooperative than intended—for example, arriving later than intended for a meeting due to an unusual traffic jam. The present research was inspired by the notion that doing a little more for one's interaction partner, which may be movitvated by empathetic feelings, can effectively reduce the detrimental effects of “negative noise,” or unintended incidents of noncooperation. Consistent with hypotheses, negative noise exhibited detrimental effects on cooperation, but such effects were absent when empathy‐motivated cooperation was present. We conclude that empathy has broad benefits for social interaction, in that it can be an effective tool for coping with misinterpreted behaviors, thereby maintaining or enhancing cooperation.

A global factor in the Hermann grid illusion or an artifact?

In the first of the present experiments, subjects were required to estimate the strength of the Hermann grid illusion in grids containing various numbers of intersectionseven though those grids were not actually presented. The positive relationship found by Wolfe (1984) for real grids was, nevertheless, replicated. It is argued that this suggests that a response bias might have been the source of his effect (although other possibilities are also noted). In addition, in a second experiment, subjects who were not aware of the fact that grid size was being manipulated (i.e., between subjects) showed no consistent effect of that factor, thus supporting the same suggestion.
