Outcomes of Home-Support Consultation on the Maintenance of Bicycle-Riding Skills for Youth With Autism Spectrum Disorder

Bicycle riding is a functional motor skill that increases physical activity opportunities, social interaction, and independence. However, bicycle riding is difficult for youth with autism spectrum disorder (ASD) to learn. This study examined the effectiveness of home-support consultation (HSC) on increasing the maintenance of independent bicycle riding following initial skill acquisition. Fifty-one youth with a confirmed ASD diagnosis learned to ride a two-wheeled bicycle during a training camp. Twenty-nine riders enrolled in a HSC intervention to promote distributed practice of the learned skill. The control cohort (N = 22) was exempt from the HSC intervention. One year following initial skill acquisition, 62.07% of the HSC cohort compared to 36.36% of the control cohort still reportedly displayed the skill. Within the HSC cohort, riders who reported at least 8 weeks of practice following acquisition on average maintained the skill. Implications of home consultation are discussed.     

Parent and Peer Predictors of Change in Attachment Security From Adolescence to Adulthood

Interview, self‐report, peer report, and observational data were used to examine parent and peer relationship qualities as predictors of relative changes in attachment security in a community sample of adolescents followed from ages 14 to 24. Early maternal supportive behavior predicted relative increases in attachment security from adolescence to adulthood, whereas psychological control and interparental hostile conflict predicted relative decreases. Peer predictors of relative increases in security included collaborative and autonomous behaviors and lack of hostile interactions, with peer predictions growing stronger for relationships assessed at later ages. Overall, models accounted for sufficient variance as to suggest that attachment security across this period is well explained by a combination of stability plus theoretically predicted change linked to social relationship qualities.     

Acquisition and extinction of facilitation in the C57BL/6J mouse

Acquisition, extinction, and transfer of facilitation were explored in a series of experiments with C57BL/6J mice. With a procedure in which an auditory target was followed by food only in the presence of a visual facilitator, Experiments 1—4 showed that the facilitator promoted magazine entries to the auditory target. This enhancement effect was eliminated by training the facilitator as a conditioned inhibitor (Experiments 1 and 3B). Enhancement was also reduced by nonreinforced presentations of the facilitator in a discrimination procedure (Experiment 1) and by simple nonreinforcement of the facilitator (Experiments 2, 3A, and 4). In contrast to the results obtained with a facilitator, simple nonreinforcement of an inhibitor, a visual cue that had signaled when an auditory target would not be reinforced, did not reduce its ability to modulate responding to that target (Experiment 4). However, both the facilitator and the inhibitor were found to transfer their modulatory effects to other targets (Experiment 4). Finally, mice demonstrated no evidence of differential responding on a biconditional discrimination procedure in which one auditory target (A1) was reinforced in the presence of one visual stimulus (L1) but not in the presence of another (L2), and a different auditory target (A2) was reinforced in L2 but not in L1 (Experiment 5). The implications of these results for analysis of the function of a facilitator are discussed.     

DAP in the ’hood: Perceptions of child care practices by African American child care directors caring for children of color

This paper presents a qualitative analysis concerning child care practices by six African American directors of subsidized child care centers located in a low-income, racial ethnic minority area of Los Angeles, California. These programs are traditionally African American programs that experienced an influx of Latino immigrant enrollment. Using the integrative framework for children of color proposed by Garcia Coll et al. [Garcia Coll, C., Crinic, K., Lamberty, G., Wasik, B., Jenkins, R., Garcia Vazquez, H., et al. (1996). An integrative model for the study of developmental competencies in minority children. Child Development, 67, 1891–1914], which places racial ethnicity in the center, we examined how these directors integrated professional standards of practice (developmentally appropriate practice) with community understandings of the role of preschool/child care in this community; the function of social stratification on their articulated practices; and their understanding as to how they include the Latino immigrant families. We discovered patterns that reflect a community-interpreted understanding of developmentally appropriate practice.     

Indexing Early Visual Memory Durability in Infancy

The goal was to examine the scope and development of early visual memory durability. We investigated individual- and age-related differences across three unique tasks in 6- to 12-month-olds (M_age = 8.87, N = 49) by examining the effect of increased delay on memory performance. Results suggest longer-term memory processes are quantifiable by 8 months using a modified Change Detection paradigm and spatial-attention cueing processes are quantifiable by 10 months using a modified Delayed Response paradigm, utilizing 500–1,250 ms delays. Performance improved from 6 to 12 months and longer delays impaired performance. We found no evidence for success on the Delayed Match Retrieval task at any age. These outcomes help inform our understanding of infant visual memory durability and its emergence throughout early development.     

Factors Influencing Preservice Teachers’ Self-Efficacy in Addressing Cultural and Linguistic Needs of Diverse Learners

Abstract

How preservice teachers perceive their readiness to work with diverse learners can indicate their future success in the classroom. Using self-efficacy theory as a conceptual base, this study examined what factors contribute to preservice teachers’ self-efficacy level in addressing English Learners’ (ELs) cultural and linguistic needs, while adopting a multi-method design. Data sources included a self-efficacy survey of a group of preservice teachers, written rationales for their self-efficacy ratings, and suggestions for improving their self-efficacy. Data analyses revealed that the preservice teachers lacked self-efficacy in communicating with ELs while showing high self-efficacy in employing different learning modalities. In addition, direct exposure through field and/or life experiences and curriculum emphasis were identified as key factors. Findings further illuminate the preservice teachers’ incongruent understandings of mainstream school culture versus ELs’ cultures, the role of culture in academic versus social and emotional domains, and lack of interconnectedness between academic excellence and cultural competency.     

PDA power at the bedside

George Washington University's Himmelfarb Health Sciences Library was investigating adding PDA resources to the collection when a medical education grant was received. Funds were used for a pilot project to compare PDA use by third-year medical students (MSIII), fourth-year medical students (MSIV), second-year physician assistant (PAII) students, and residents in the clinical setting. The PDA Committee evaluated various titles by the following criteria: both Palm and PocketPC operating systems compatibility, ease of use, depth of information, product cost, and a wide target audience. Griffith's 5 Minute Clinical Consult by Skyscape was selected. Library registration was required to receive the software and PDA downloading instructions. A short, Web-based questionnaire was developed to evaluate the product's use in the clinical setting. A low response rate of 74 questionnaires (23% of participants) was received and analyzed in March 2004. As additional funding becomes available, PDA software will be seriously considered as additions to the collection.     

Communicating openness in deliberation

Normative and practical accounts of deliberative democracy cite open-mindedness as a key feature of good deliberation. Yet scholars have often focused on attitude change or self-report measures to empirically demonstrate openness. This paper draws on grounded practical theory to understand openness as a discursive stance in public deliberation. Openness is used to address four practical problems encountered in deliberation: disagreement, opinion formation, dysfunctional community problem-solving, and deliberative sense making. Indicating openness and expressing attitude change are different discursive practices. Expecting participants to refrain from forming opinions before deliberation may be naïve. Instead, participants’ eagerness to make sense of deliberation by invoking shared understanding and openness should be used to develop meta-consensus.
