A study of field independent biased mental ability tests in community college science classes

Many schools use mental ability test scores as a basis for grouping students and planning their educational needs. The widespread use of these test scores throughout public and private schools demands that test items be unbiased. One way in which tests could be biased, that has not been thoroughly investigated, is the inadvertent use of analytical skill items favoring one perceptual orientation over another. This study investigated analytical skill items on the Otis-Lennon Mental Ability Test for field independent bias. Using as analysis of variance and discriminant analysis, the results indicated that the Otis-Lennon Mental Ability Test was biased in favor of individuals with a field of independent perceptual orientation.     

Disruption of latent inhibition by interpolation of task-irrelevant stimulation between preexposure and conditioning

Latent inhibition refers to attenuated responding to a conditioned stimulus (CS) that was repeatedly presented without reinforcement prior to the CS-unconditioned stimulus (US) pairings. Using water-deprived rats as subjects, we observed that interpolating task-irrelevant stimulation between the preexposure and conditioning phases of a latent inhibition procedure attenuated latent inhibition (Experiments 1A, 1B, and 2). Apparently, interpolated stimulation segments the preexposure and conditioning treatments into two separate experiences, much in the same way that a change of context would. Consistent with this view, the interpolated stimulation did not disrupt latent inhibition if it was also presented during both preexposure and conditioning (Experiment 3). We view these results as analogous to those of Escobar, Arcediano, and Miller (2003), who suggested that the difficulty in observing latent inhibition in human adults is related to the segmentation between preexposure and conditioning caused by the usual interpolation of instructions in preparations with humans.     

Relations Among Maternal Literacy Beliefs, Home Literacy Practices, and the Emergent Literacy Skills of Preschoolers With Specific Language Impairment

Self-reported maternal literacy beliefs and home literacy practices were compared for families of children with typicially developing language skills (TL, n = 52) and specific language impairment (SLI, n = 56). Additionally, the present work examined whether maternal beliefs and practices predicted children's print-related knowledge. Mothers filled out 2 questionnaires asking about their literacy beliefs and practices while children's print-related knowledge was assessed directly. Results indicated that mothers of children with SLI held somewhat less positive beliefs about literacy and reported engaging in fewer literacy practices compared to mothers of children with TL. For the entire sample, maternal literacy practices and beliefs predicted children's print-related knowledge, although much of this association was accounted for by maternal education. Subgroup analyses focused specifically on children with SLI showed there to be no relation between maternal literacy beliefs and practices and children's print-related knowledge. The present findings suggest that the home literacy experiences of children with SLI, and the way that these experiences impact print-related knowledge, may differ in important ways from typical peers.     

Helping Youth in Underserved Communities Envision Possible Futures

Empowering youth through the exploration of their possible futures is a fresh and innovative approach to the Teaching Personal and Social Responsibility model (TPSR). The purpose of this study was to examine the combination of TPSR with the theory of possible selves. This combination, called the Career Club, was a program specifically designed to better assist students in understanding and facilitating reflective discussions on their future decisions. Career Club was taught weekly for nine sessions, 90 min each, at an inner city elementary school in a large metropolitan city. Participants comprised 12 seventh- and eighth-grade boys and girls who had at least 1 year and up to 5 years of experience in a TPSR program. Data sources included document analysis, lesson observations, formal interviews, and observational field notes. Themes were classified into the following categories: hopedfor-selves and feared selves—a delicate balance, coaching as a necessary component, and coming to understand possible futures. These results indicated that Career Club was effective in providing the participants a meaningful career exploration in coaching. Data also suggested these coaching experiences facilitated reflective discussions on realizing their future orientation choices.
