In this paper, through the theoretical lens of life-course research and reproduction theory, we employ 15 years of longitudinal data from the British Columbia, Canada "Paths on Life's Way" project to examine the extent to which educational and career pathways of this cohort of 1988 high school graduates are gendered, individualized,…

Background: The desirable extent of curriculum choice to be offered to students remains a central policy question in England. Previous studies of the impact of the introduction of a common curriculum for 14-16 year olds in 1988 have suggested that some gender differences were narrowed as a result. These studies examined subject choice either in…

An evaluation of a course aimed at developing university students' understanding of the nature of scientific measurement and uncertainty is described. The course materials follow the framework for metrology as recommended in the "Guide to the Expression of Uncertainty in Measurement" (GUM). The evaluation of the course is based on…

Purpose: The current study sought to compare interventional materials intended to raise public awareness of the caregiving practices connected to Shaken Baby Syndrome (SBS). Two hundred and sixty four adults (mean age 32 years) were recruited for participation through convenience sampling at a large Northeastern university. Participants fell into…

The Wednesday before Thanksgiving presents a challenge to teachers in many U.S. schools. Some students are absent because they are traveling to be with their extended families for the holiday. Other students, assuming that nothing important will happen at school when so many of their peers are absent, may also be absent. One school's solution to…

This study examined the idea that expectations of behavior in hypothetical situations involving potential moral transgressions are related to emotion attributions relating to both moral and cost-benefit considerations. We asked younger (14 years 5 months) and older (16 years 1 month) female and male adolescents (a) to make predictions about the…

In a sample of 7,695 families in the prospective, nationally representative British Millennium Cohort Study, this study examined whether characteristics of the 1st-born child predicted parents' timing and probability of having another child within 5 years after the 1st child's birth. Infant temperament was assessed with the Carey Infant…

Near the end of his illustrious career, Gottlieb lamented the continued dominance of heritability analysis in human psychology and the difficulties in winning support for the developmental point of view. Recent, spectacular progress in molecular genetic neuroscience and the genetic study of behavior, however, is rendering heritability analysis…

Although errors in reasoning about conditional probability have been the focus of interest of psychologists for a long time, the development of conditional reasoning in school students has received little attention. This paper considers the responses of 69 students across grades 3 to 13 in an attempt to model the development of appropriate…

Processing language requires the retrieval of concepts from memory in response to an ongoing stream of information. This retrieval is facilitated if one can infer the gist of a sentence, conversation, or document and use that gist to predict related concepts and disambiguate words. This article analyzes the abstract computational problem…

The paper discusses findings of a study that investigated Malawian students' meanings for some probability vocabulary. The study explores the meanings that, prior to instruction, students assign to some words that are commonly used in teaching probability. The aim is to have some insight into the meanings that students bring to the classroom. The…

Three sets of rare baseball events--pitching a no-hit game, hitting for the cycle, and turning a triple play--offer excellent examples of events whose occurrence may be modeled as Poisson processes. That is, the time of occurrence of one of these events doesn't affect when we see the next occurrence of such. We modeled occurrences of these three…

Reports an error in "Finding Useful Questions: On Bayesian Diagnosticity, Probability, Impact, and Information Gain" by Jonathan D. Nelson (Psychological Review, 2005[Oct], Vol 112[4], 979-999). In Table 13, the data should indicate that 7% of females had short hair and 93% of females had long hair. The calculations and discussion in the article…

Purpose: Significant threshold differences on retest for pure-tone audiometry are often evaluated by application of ad hoc rules, such as a shift in a pure-tone average or in 2 adjacent frequencies that exceeds a predefined amount. Rules that are so derived do not consider the probability of observing a particular audiogram. Methods: A general…

Latent class analysis (LCA) is a statistical method used to identify a set of discrete, mutually exclusive latent classes of individuals based on their responses to a set of observed categorical variables. In multiple-group LCA, both the measurement part and structural part of the model can vary across groups, and measurement invariance across…
