Relations among academic stress, depression, and suicidal ideation were examined in 1,108 Asian adolescents 12-18 years old from a secondary school in Singapore. Using Baron and Kenny's [J Pers Soc Psychol 51:1173-1192, 1986] framework, this study tested the prediction that adolescent depression mediated the relationship between academic stress…

Binding theory (e.g., Chomsky, 1981) has played a central role in both syntactic theory and models of language processing. Its constraints are designed to predict that the referential domains of pronouns and reflexives are nonoverlapping, that is, are complementary; these constraints are also thought to play a role in online reference resolution.…

The concept of imminent suicide is examined. A search of National Electronic Library for Mental Health, the Cochrane Library, PubMed, OVID and MD Consult databases was conducted using the terms "suicide, imminent." The term "imminent" frequently appears in the mental health literature, finding common usage among clinicians. It is also a legal term…

Binary outcome data are common in research and evaluation. They are often analyzed using logistic regression, and results of these analyses are often reported in the form of odds ratios (ORs). However, ORs are not directly interpretable in the metric commonly used in policy-relevant discussions, which concerns probabilities. ORs are unfamiliar to…

Should one be more confident when predicting the whole (or an event based on a larger sample) from the part (or an event based on a smaller sample) than when predicting the reverse? The relevant literature on judgment under uncertainty argues that such predictions are symmetrical but that, as an empirical matter, people often fail to appreciate…

In error management training, participants are explicitly encouraged to make errors and learn from them. Error management training has frequently been shown to lead to better performance than conventional trainings that adopt an error avoidant approach. The present study investigated self-regulatory processes mediating this effect. Fifty-five…

To become more skilled as pedestrians, children need to acquire a view of the traffic environment as one in which road users are active agents with different intentions and objectives. This paper describes a simulation study designed to explore children's understanding of drivers' intentions. It also investigated the effect of training children's…

Researchers who advocate the hypothesis that cognitive development is akin to theory formation have also suggested that young children possess distinct systems for explaining physical, psychological, and biological principles (see, e.g., Wellman & Gelman, 1992). One way this has been investigated is by examining how children explain human action:…

Traditional models of human memory have postulated the need for a brief phonological or verbatim representation of verbal input as a necessary gateway to a higher level conceptual representation of the input. Potter has argued that meaningful sentences may be encoded directly in a conceptual short-term memory (CSTM) running parallel in time to…

Several competing theories of short-term memory can explain serial recall performance at a quantitative level. However, most theories to date have not been applied to the accompanying pattern of response latencies, thus ignoring a rich and highly diagnostic aspect of performance. This article explores and tests the error latency predictions of…

The authors investigated absolute and relative metacomprehension accuracy as a function of verbal ability in college students. Students read hard texts, revised texts, or a mixed set of texts. They then predicted their performance, took a multiple-choice test on the texts, and made posttest judgments about their performance. With hard texts,…

Researchers conducted two studies in Broward County (Fla.) Public Schools. The first study examined the utility of the Preliminary SAT (PSAT) for predicting future success on college entrance examinations and in advanced placement (AP) courses. The second examined the relationship between PSAT scores and subsequent year AP enrollment status for…

The dataset presented here illustrates to students the utility of logistic regression. Its analysis results in a fit that explains much of how senators vote on a particular bill, and allows for quantification of the effects of ideology and money on the vote. A number of interesting quantitative interpretations follow from a good fit. A successful…

The present study tests a model of category effects upon stimulus estimation in children. Prior work with adults suggests that people inductively generalize distributional information about a category of stimuli and use this information to adjust their estimates of individual stimuli in a way that maximizes average accuracy in estimation (see…

Prospective studies have been held out as a kind of Holy Grail in research about remembering or forgetting child sexual abuse. They seem to hold the perfect answer to the verification problems that plague retrospective self-reports in the clinical literature. Prospective studies begin with verified cases of abuse. Then they require detective work…
