Many explanations of the difficulties associated with interpreting object relative clauses appeal to the demands that object relatives make on working memory. MacDonald and Christiansen [MacDonald, M. C., & Christiansen, M. H. (2002). "Reassessing working memory: Comment on Just and Carpenter (1992) and Waters and Caplan (1996)." "Psychological…

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. The relationship between these areas and comparison to a control group is warranted. Method: 54 individuals with CdLS were compared with 46 participants with…

A meta-analysis of 41 studies examined the effect of choice on intrinsic motivation and related outcomes in a variety of settings with both child and adult samples. Results indicated that providing choice enhanced intrinsic motivation, effort, task performance, and perceived competence, among other outcomes. Moderator tests revealed the effect…

This study examines the effects of ethics training on the attitudes, knowledge-based scores, and analysis of ethical dilemmas among office professionals. A treatment- and control-group design was used with variables of interest measured before, immediately after, and ninety days following completion of a six-hour ethics training workshop. A…

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,…

The present study aimed at examining the effectiveness of a team-sports-based life-skills program taught as part of physical education lessons. One hundred sixty-five sixth and eighth graders were assigned either in an experimental or in a control group and received an abbreviated version of SUPER, a team-sports-based program. The program focused…

This randomized study tested the effects of 2 prebirth interventions, Minnesota Early Learning Design coparenting and childbirth curricula, on young African American and Hispanic fathers and their adolescent partners (N = 154). The coparenting intervention (n = 44) was associated with changing fathers' perceptions of their coparenting behavior…

Episodic and semantic autobiographical memories were examined in a group of adults with autism spectrum disorders (ASD) and a control group matched for age, gender and IQ. Results demonstrated a personal episodic memory deficit in the ASD group in the absence of a personal semantic memory deficit, suggesting a deficit dissociation between these…

Purpose: This study describes written and spoken narrative skills of school-age individuals with Down syndrome (DS). Method: Twenty-one students with DS (age 6;6 [years;months]-19;10) and 17 reading-matched, typically developing (TD) controls (age 4;9-10;9) were matched using Word Identification subtest raw scores (Woodcock Reading Mastery…
