Slow and steady? Strategic adjustments in response caution are moderately reliable and correlate across tasks.

Speed-accuracy trade-offs are often considered a confound in speeded choice tasks, but individual differences in strategy have been linked to personality and brain structure. We ask whether strategic adjustments in response caution are reliable, and whether they correlate across tasks and with impulsivity traits. In Study 1, participants performed Eriksen flanker and Stroop tasks in two sessions four weeks apart.

Low and variable correlation between reaction time costs and accuracy costs explained by accumulation models: Meta-analysis and simulations.

The underpinning assumption of much research on cognitive individual differences (or group differences) is that task performance indexes cognitive ability in that domain. In many tasks performance is measured by differences (costs) between conditions, which are widely assumed to index a psychological process of interest rather than extraneous factors such as speed-accuracy trade-offs (e.g.

Exaggerations and Caveats in Press Releases and Health-Related Science News.

Background: Exaggerated or simplistic news is often blamed for adversely influencing public health. However, recent findings suggested many exaggerations were already present in university press releases, which scientists approve. Surprisingly, these exaggerations were not associated with more news coverage.

How readers understand causal and correlational expressions used in news headlines.

Also, the second paragraph of the author note should have included the following: "Amy Barrington contributed to the design and data collection for Experiments 2 and 3.

Transformation priming helps to disambiguate sudden changes of sensory inputs.

Retinal input is riddled with abrupt transients due to self-motion, changes in illumination, object-motion, etc. Our visual system must correctly interpret each of these changes to keep visual perception consistent and sensitive. This poses an enormous challenge, as many transients are highly ambiguous in that they are consistent with many alternative physical transformations.

The association between exaggeration in health related science news and academic press releases: retrospective observational study.

Objective: To identify the source (press releases or news) of distortions, exaggerations, or changes to the main conclusions drawn from research that could potentially influence a reader's health related behaviour.

Design: Retrospective quantitative content analysis.

Setting: Journal articles, press releases, and related news, with accompanying simulations.
