This study evaluates the impact of using the software program AudioMetro, a tool that supports the orientation and mobility of people who are blind in the Metro system of Santiago de Chile. A quasi-experimental study considering experimental and control groups and using the paired Student's t in a two sample test analysis (pretest-posttest) was…

This study examines the impact of the Learning Strategies Curriculum (LSC), an adolescent reading intervention program, on 6th- and 9th-grade students' reading comprehension and strategy use. Using a randomized treatment-control group design, the study compared student outcomes for these constructs for 365 students who received daily instruction…

Objective:This report extends earlier accounts by addressing the effects of the Strong African American Families (SAAF) program across 65 months. Two hypotheses were tested: (a) Rural African American youths randomly assigned to participate in SAAF would demonstrate lower rates of alcohol use than would control youths more than 5 years later, and…

The objective of the present research study was to understand what benefits the use of audiobooks (both school-books and books of various genres, recorded on digital media) could bring to preadolescents and adolescents with developmental dyslexia. Two groups, each consisting of 20 adolescents, were compared. The experimental group used the…

The intersection of Theory of Mind (ToM) processing and complex narrative comprehension in high functioning autism was examined by comparing cortical activation during the reading of passages that required inferences based on either intentions, emotional states, or physical causality. Right hemisphere activation was substantially greater for all…

Studies of autobiographical memory have shown that the degree to which individuals focus on themselves vs. social relations in their memories varies markedly across cultures. Do the differences result from differing cultural self-views (i.e., an autonomous vs. a relational sense of self), as often suggested in the literature? Experimental evidence…

Background: Self-injury, sleep problems and health problems are commonly reported in Cornelia de Lange Syndrome (CdLS) but there are no comparisons with appropriately matched participants.

Eyewitness identification decisions are vulnerable to various influences on witnesses' decision criteria that contribute to false identifications of innocent suspects and failures to choose perpetrators. An alternative procedure using confidence estimates to assess the degree of match between novel and previously viewed faces was investigated.…

This article considers the underlying assumptions related to the use of random assignment in educational research and evaluation; more specifically, the ability of random assignment to create similar comparison groups for the purpose of determining the effectiveness of educational programmes. In theory, randomly assigning individuals to comparison…

The purpose of this study is to investigate the performance of adults with language-based learning disorders (L/LD) and normal language controls on verbal short-term and verbal working memory tasks. Eighteen adults with L/LD and 18 normal language controls were compared on verbal short-term memory and verbal working memory tasks under low,…

In three experiments, we explore the effects of phonological properties such as neighbourhood density and frequency on speech production in Spanish. Specifically, we assess the reliability of the recent observation made by Vitevitch and Stamer (2006), according to which the neighbourhood effect in Spanish has a reverse polarity to that observed in…

In this article, we report the results of an evaluation study of a program for couples during the transition to parenthood on father involvement in child care. One-hundred-twenty couples were assigned to 1 of the 3 groups: a treatment group that received the Welcome Baby new-parent, home-visiting program focused on infant development and health,…
