Severe Violence During Adolescence and Early Adulthood and Its Relation to Anticipated Rewards and Costs

This report compares the effects (concurrent and lagged) of the anticipated rewards and costs of violent crime on engagement in severe violence in a sample of male juvenile offenders (N = 1,170; 42.1% black, 34.0% Hispanic, 19.2% white, and 4.6% other; ages 14–18 at baseline). Anticipated rewards (social approval, thrill) are more predictive of concurrent severe violence than are anticipated costs (social disapproval, risk of punishment). The analysis finds no evidence that perceptions of the rewards and costs of violent crime influence engagement in severe violence 6 months later. The results support the view that adolescence is a time of heightened reward salience but raise doubt about the longitudinal predictive validity of perceptions about crime during this time of life.     

Physical versus virtual manipulative experimentation in physics learning

The aim of this study was to investigate whether physical or virtual manipulative experimentation can differentiate physics learning. There were four experimental conditions, namely Physical Manipulative Experimentation (PME), Virtual Manipulative Experimentation (VME), and two sequential combinations of PME and VME, as well as a control condition (i.e., traditional instruction with absence of PME or VME). Undergraduate students' understanding of physics concepts in the domain of heat and temperature was tested in a pre- and posttest design that involved 182 participants assigned to the four experimental groups and 52 participants assigned to the control group. Conceptual tests were administered to assess students' understanding before, during and after instruction. The analyses revealed that the four experimental conditions were equally effective in promoting students' understanding of concepts in the domain of heat and temperature and better than the control condition; hence, manipulation, either physical or virtual manipulation, and not physicality, as such, at least in a context like the one of the present study, is important in physics learning.     

Massive preexposure and preexposure in multiple contexts attenuate the context specificity of latent inhibition

Latent inhibition, which refers to attenuated responding to a conditioned stimulus (CS) after CS-unconditioned stimulus (CS-US) pairings as a result of CS-alone presentations prior to the pairings, is often attenuated if preexposure and conditioning occur in different contexts (i.e., it is context specific). Here we report two conditioned lick suppression experiments, using rat subjects, that examined whether manipulations known to attenuate the context specificity of extinction could also eliminate the context specificity of latent inhibition. Context specificity of latent inhibition was eliminated when the CS was preexposed in multiple contexts (Experiment 1) and when the CS was massively pre-exposed in the training context alone (Experiment 2). These results and their practical implications are discussed in the framework of contemporary theories of latent inhibition.     

Geriatric Expertise among Medical School Faculty: Preparing for the Challenges of an Aging Population

This study examined non-geriatrician physicians' experiences in a geriatrics-focused faculty development program, and effects of the program on their geriatrics knowledge and their teaching and practice. In-depth interviews were conducted with all physicians (n = 26) participating in the Dean's Faculty Scholars in Aging program. Most participants reported substantial gains in geriatric knowledge, and in the knowledge that older people are a distinct group with special needs. Most reported substantial changes in the way they care for older patients. Most reported incorporating notably more geriatrics content into their teaching. The program may serve as a process to address the growing need for physicians with geriatric knowledge.     

Teacher education,motivation, compensation,workplace support,and links to quality of center-based child care and teachers’ intention to stay in the early childhood profession

The purposes of this study were to present a conceptual model for selection into the early childhood profession and to test the model using contemporaneous assessments. A stratified random sample of center-based child care providers in 4 Midwestern states (n = 964) participated in a telephone interview, and 223 were also assessed with the Early Childhood Environment Rating Scale—Revised or the Infant–Toddler Environment Rating Scale to rate global observed quality, and the Caregiver Interaction Scale to rate interactional quality. When the model was tested with infant–toddler and preschool teachers combined, having a Child Development Associate (CDA) predicted global observed quality, education years and child development coursework predicted compensation, and compensation predicted observed quality. When the model was tested separately for infant–toddler teachers, years of education and child development coursework predicted compensation, but none of the education variables predicted observed quality and compensation did not predict observed quality. For preschool teachers, years of education predicted compensation and having a CDA predicted observed quality, but compensation did not predict observed quality. For all of the models, only motivations for child care work predicted intention to stay in the profession. No variables in the structural equation models predicted interactional quality.     

Advances in early years screening for dyslexia in the United Kingdom

In this article, we describe two United Kingdom (UK) screening tests for dyslexia: the Dyslexia Early Screening Test (DEST) and the Cognitive Profiling System (CoPS 1), both normed and designed to be administered by teachers to children four years and older. We first outline the political context in the UK, which for the first time, makes the use of such tests viable. We then outline the research programs behind and the components of each test; reliability and validity are also discussed. Information is presented on the tests in use. We conclude that tests such as these have the potential to identify children as at risk before they fail, halting the cycle of emotional and motivational problems traditionally associated with dyslexia. Both tests are appropriate for use in the United States, and initial reactions from the education sector have been favorable.
