Beyond Likert ratings: Improving the robustness of developmental research measurement using best-worst scaling.

Some of the 'best practice' approaches to ensuring reproducibility of research can be difficult to implement in the developmental and clinical domains, where sample sizes and session lengths are constrained by the practicalities of recruitment and testing. For this reason, an important area of improvement to target is the reliability of measurement. Here we demonstrate that best-worst scaling (BWS) provides a superior alternative to Likert ratings for measuring children's subjective impressions.

Familiar size effects on reaction time: When congruent is better.

Familiar size is known to influence our perception of object's size and distance. In this study, we examined whether or not simple RTs (RTs) are also affected by prior knowledge of objects' size. In a series of experiments, participants were asked to respond as quickly as possible to briefly presented images of familiar objects, equated for luminance and retinal size.
