Current higher education is characterized by a proliferation of distance education programs and by an increasing inclusion of nontraditional students. In this study we investigated whether and to what extent nontraditional students are particularly at risk for attrition (vs. graduating) from distance education programs. We conducted a secondary…

Before starting school, many children reason logically about concepts that are basic to their later mathematical learning. We describe a measure of quantitative reasoning that was administered to children at school entry (mean age 5.8 years) and accounted for more variance in a mathematical attainment test than general cognitive ability 16 months…

Our cluster receives a number of referrals from schools requesting support with the implementation of assistive technology tools (particularly word prediction software) to support struggling reluctant writers. It is widely acknowledged that writing is pivotal for academic success, and when a learner has difficulty expressing their ideas they often…

In this conceptual article, we integrate existing literature on early school transitions, ecological systems theory, and student-teacher relationships to propose a framework for investigating the transition to school for children with autism spectrum disorders (ASD). A review of the literature suggests that the quality of early student-teacher…

The purpose of this proposal is to examine whether variability in the quality of teachers' interactions (Emotional Support, Classroom Organization, Instructional Support) with students is systematically related to the children's development. In other words, the authors examine whether the amount that teachers vary over the course of a day is a…

Many words can be used flexibly: a book can be physically heavy, but also have provocative content, a "chicken" might live in a coop, but could also be tasty to eat. What do the uses of "polysemous" words such as these reveal about the structure of language and thought? Paper 1 examined 4-year-old children's representations of polysemous words…

The present study investigated within a substance abuse treatment center the influence of family therapy on flexibility and cohesion among family members. Past studies have suggested adolescents who abuse substances exist in families who have a lack of balance of flexibility and cohesion. Unfortunately, few studies have examined the influence of…

Verb retrieval difficulties are common in aphasia; however, few successful treatments have been documented (e.g. Conroy, P., Sage, K., & Lambon Ralph, M. A. (2006). Towards theory-driven therapies for aphasic verb impairments: A review of current theory and practice. "Aphasiology", 20, 1159-1185). This study investigated the efficacy of a novel…

Although nowadays there are mythbusting teams ready to empirically confirm or deny advertising claims that may seem too good to be true, it is often economically prohibitive to perform the kinds of experiments that are called for. It is therefore sometimes more sensible and efficacious to perform a thought experiment instead, especially if the…

Multiple object tracking (MOT) is an attentional task wherein observers attempt to track multiple targets among moving distractors. Contour interpolation is a perceptual process that fills-in nonvisible edges on the basis of how surrounding edges (inducers) are spatiotemporally related. In five experiments, we explored the automaticity of…

The proposal that friendships provide a context for the development of social skills is widely accepted. Yet little research exists to support this claim. In the present study, children and adolescents (N = 912) were presented with vignettes in which a friend encountered a social stressor and they could help the friend and vignettes in which they…

Tests, as learning events, can enhance subsequent recall more than do additional study opportunities, even without feedback. Such advantages of testing tend to appear, however, only at long retention intervals and/or when criterion tests stress recall, rather than recognition, processes. We propose that the interaction of the benefits of testing…

Whether recollection is a threshold or signal detection process is highly controversial, and the controversy has centered in part on the shape of receiver operating characteristics (ROCs) and z-transformed ROCs (zROCs). U-shaped zROCs observed in tests thought to rely heavily on recollection, such as source memory tests, have provided evidence in…

Forming implementation intentions (i.e. action plans that specify when, where and how a person will act) could be effective in promoting condom use on a large scale. However, the technique implies that people are able to form high quality implementation plans that are likely to induce behaviour change. Young single females, aged 16-30 years old,…

There are two common approaches to sub-typing the well-documented heterogeneity within antisocial behavior: age-of-onset (i.e., childhood-onset versus adolescence-onset; see "Moffitt" 1993) and behavioral (i.e., physical aggression versus non-aggressive rule-breaking). These approaches appear to be associated, such that aggression is more…
