Anticipatory spatial representation of 3D regions explored by sighted observers and a deaf-and-blind-observer

Viewers who study photographs of scenes tend to remember having seen beyond the boundaries of the view [boundary extension; J. Exp. Psychol. Learn. Mem. Cogn. 15 (1989) 179]. Is this a fundamental aspect of scene representation? Forty undergraduates explored bounded regions of six common (3D) scenes, visually or haptically (while blindfolded) and then the delimiting borders were removed. Minutes later they reconstructed boundary placement. Boundary extension occurred: mean areas were increased by 53% (vision) and by 17% (haptics). A deaf-and-blind woman (KC) haptically explored the same regions. Although a "haptic expert", she too remembered having explored beyond the boundaries, with performance similar to that of the blindfolded-sighted. Boundary extension appears to be a fundamental aspect of spatial cognition. Possibly constrained by the "scope" of the input modality (vision>haptics), this anticipatory spatial representation may facilitate integration of successively perceived regions of the world irrespective of modality and the perceiver's sensory history.     

Correlations of scores on the developmental test of visual-motor integration and copying test in a South African multi-ethnic preschool sample

This study assessed the intercorrelations of scores on the Developmental Test of Visual-Motor Integration, the locally standardized Copying Test, and teachers' ratings of scholastic skills in a South African multi-ethnic preschool sample. The study also investigated whether cultural and socioeconomic factors might influence test data. Participants were 71 Black, 101 Coloured, and 66 White children attending preschools in a semirural district. Participants' ages ranged from 4 yr., 9 mo. to 7yr., 0 mo. (M=5.8 yr., SD= 0.3 yr.). Analysis yielded a correlation of .75 between the test scores and supports the suitability of the widely used Developmental Test of Visual-Motor Integration in a multi-ethnic sample. Scores on the Copying Test correlated higher with teachers' ratings. However, significant differences in test performance among groups by race and socioeconomic status suggest the rate of perceptual-motor development may be related to cultural factors. Normative data are reported for groups by race and socioeconomic status.     

“But Many of These Problems are About Funds…”: The Challenges Immigrant Settlement Agencies (ISAs) Encounter in a Suburban Setting in Ontario,Canada

A large number of studies have focused on the neoliberal political and economic restructuring of non-profit immigrant settlement agencies (ISAs) through a policy analysis framework. While policy analysis is key to determining how resources are distributed among non-profit organizations, the challenges that ISAs encounter in planning and delivering services extend beyond limited financial resources in the sector. This research focuses on the system-level challenges ISAs encounter in planning and delivering services to newcomers in the suburban municipality of the Peel Region, Ontario, Canada. Twenty-one semi-structured interviews were conducted with frontline staff and executive directors in settlement organizations in Peel Region, Ontario, Canada, to understand the complex challenges they face within a highly federalized and neoliberal policy environment. The results indicate that although funding dollars are a large concern for ISAs, the conditions attached to funding, such as the types of programs settlement providers are able to offer, mandatory quotas, and restrictive eligibility criteria, hinder ISAs from being able to plan and implement programs that better respond to the needs of immigrants in Peel Region. The results also demonstrate that restrictive funding criteria contribute to competition with other ISAs for limited resources and challenge the structure and continuity of programs. Many of these challenges are exacerbated by the transportation system unique to suburban settings.     

Developmental coordination disorder: exploration of a cerebellar hypothesis

This study explored the hypothesis of a specific cerebellar dysfunction in children with developmental coordination disorder (DCD): motor adaptation. The performance of a group of children with DCD (3 girls and 6 boys) was compared to that of a control group (5 girls and 6 boys) on a measure of motor adaptation, the prism adaptation test (PAT). Children were between 6 years 11 months and 11 years 10 months of age. Between-group differences were only found for PAT variables related to throwing accuracy, the DCD group being more variable and less accurate than the control group. While no between-group differences were found for the adaptation variables, individual data analysis revealed that only three children in the DCD group obtained normal adaptation variables. While these findings do not confirm the hypothesis of a cerebellar dysfunction, they also do not refute it. It is possible that the poor throwing accuracy of the DCD group masked the findings for some of the PAT variables. Further exploration of the function of the cerebellum among children with DCD is needed.     

Therapeutic group approaches in an inpatient facility for children and adolescents: A 15-year perspective

Inner city, psychiatrically hospitalized adolescents are accessible to group therapy intervention. We developed a unique approach combining Slavson's theories with principles of family treatment and psychoanalytic theory. The group was conceptualized as a corrective family experience with the therapists functioning as model parents. Our model relies on a four-phase process, which is discussed.
