Speed accuracy tradeoff? Not so fast: Marginal changes in speed have inconsistent relationships with accuracy in real-world settings

Published in PsyArXiv, 2021

Using a large corpus of 29 response time datasets containing data from cognitive tasks without experimental manipulation of time pressure, we probe whether the speed-accuracy tradeoff holds across a variety of tasks using idiosyncratic within-person variation in speed and find inconsistent relationships between marginal increases in time spent responding and accuracy.

False discovery in the analysis of interactions as a function of the distributional and metric properties of the outcome

Published in PsyArXiv, 2021

Focusing on a variety of models for non-continuously distributed outcomes (binary, count, and ordinal outcomes), we show that attempts to use the linear model for estimating interaction effects can be catastrophic in some settings.

Variation in respondent speed and its implications: Evidence from an adaptive testing scenario

Published in PsyArXiv, 2021

We take advantage of a large dataset from the adaptive NWEA MAP Growth Reading Assessment to shed light on emergent features of response time behavior, identifying two behaviors in particular.

Rapid online assessment of reading ability

Published in Scientific Reports, 2021

The self-administered, Rapid Online Assessment of Reading ability (ROAR) developed here overcomes the constraints of resource-intensive, in-person reading assessment, and provides an efficient and automated tool for effective online research into the mechanisms of reading (dis)ability.

Are Changes in Reported Social-Emotional Skills Just Noise? The Predictive Power of Longitudinal Differences in Self-Reports

Published in Under review, 2020

We show that changes in self-reported social-emotional skills predict changes in both achievement and attendance.
