The literature indicates that perceived racism tends to be associated with adverse psychological and physiological outcomes; however, findings in this area are not yet conclusive. In this meta-analysis, we systematically reviewed 66 studies (total sample size of 18,140 across studies), published between January 1996 and April 2011, on the…

Current evidence demonstrating the importance of language play in second-language (L2) development rests largely on qualitative analyses of L2 discourse. Although these rich descriptions have illustrated a number of important functions of language play, further study of the phenomenon is necessary to understand its potential to facilitate…

Objective: Little is known about what factors and supports youths identify as important for their sustained recovery after substance abuse treatment, and if their caregivers and treatment staff identify similar needs. The purpose of this study was to explore what youths, caregivers, and staff perceive as important to remain substance free after…

The continuously growing demand for program results has produced an increased need for evaluation capacity building (ECB). The "Integrative ECB Model" was developed to integrate concepts from existing ECB theory literature and to structure a synthesis of the empirical ECB literature. The study used a broad-based research synthesis method with…

In this meta-analysis, we give a comprehensive overview of the effects of meditation on psychological variables that can be extracted from empirical studies, concentrating on the effects of meditation on nonclinical groups of adult meditators. Mostly because of methodological problems, almost 3/4 of an initially identified 595 studies had to be…

Visual literacy, the ability to interpret and create external representations (ERs), is essential to success in biochemistry. Studies have been conducted that describe students' abilities to use and interpret specific types of ERs. However, a framework for describing ERs derived through a naturalistic inquiry of biochemistry classrooms has not…

Confidence is an important issue for biology students in handling computational concepts. This paper describes a practical in which honours-level bioscience students simulate complex animal behaviour using StarLogo TNG, a freely-available graphical programming environment. The practical consists of two sessions, the first of which guides students…

This research investigated the rough-and-tumble play of 17 five-year-old children in two early childhood settings. The study resulted in an increased understanding of the forms of rough-and-tumble play displayed by young children. This study demonstrates that both boys and girls are engaged in a variety of rough-and-tumble play behaviours.…

The purpose of this study was to determine the effect of varied accent/articulation marks on listeners' perceptions of forcefulness of attack and length of sustain in trombone articulations. Musicians (N = 68) were asked to listen to a series of seven short musical excerpts in which a predefined set of pitches would be accented. Participants rated…

This study investigates the impact of working memory (WM) load on response conflicts arising from spatial (non) correspondence between irrelevant stimulus location and response location (Simon effect). The dominant view attributes the Simon effect to automatic processes of location-based response priming. The automaticity view predicts…

Background: Expressed emotion (EE) is a measure of family emotional climate found to be predictive of symptom levels in a range of psychiatric, medical, and developmental disorders, including autism. Method: Employing data from 104 mothers of children with autism, this study examines the Autism-Specific Five Minute Speech Sample (AFMSS), a…

Significant sex differences in the well-documented relationship between stress hormones and memory have emerged in recent studies. The potentiating effects of glucocorticoids on memory vary across the menstrual cycle, suggesting a potential interaction between these stress hormones and endogenously cycling sex hormones. Here, we show that memory…

Using meta-analytic tests based on 87 statistically independent samples, we investigated the relationships between the five-factor model (FFM) of personality traits and organizational citizenship behaviors in both the aggregate and specific forms, including individual-directed, organization-directed, and change-oriented citizenship. We found that…

This discourse analysis study examines the use of online texts in the live conversations of adolescents at and around computers in the Young Adult section of a Midwestern public library serving a diverse SES population. On the cusp of cyberspace, where online texts influence conversation and the conversation influences the creation of online…

When watching others describe events, does information from their speech and gestures affect our memory representations for the gist and surface form of the described events? Does our reliance on these memory representations change over time? Forty participants watched videos of stories narrated by an actor. Each story included three target events…
