A flowchart of how our ten principles fit together. The flowchart starts with an online experiment idea. Principles 1 through 4 are, in order, Maximize the advantages; Plan for technical variability; Plan for behavioral variability; and Validate your experiment. At this point, researchers must decide whether the trade-off of pros to cons favors conducting the experiment online. The experiment then passes through: Recruit participants strategically; Instruct clearly; Make it engaging; Collect data comprehensively; Respect your participants; and Make it discoverable. This then loops back to a new online experiment idea, using all of the learnings to improve future experiments.

New preprint with @tsay.bsky.social. We synthesise the literature and our experience conducting sensorimotor experiments online to present ten principles for crowdsourcing human behaviour online, giving guidance on navigating the benefits and pitfalls of online testing

This has important implications for models of visuomotor adaptation. In particular, the group-level smooth, gradual increase in explicit adaptation in response to a perturbation appears to be an artifact of averaging across participants who show a moment of insight with different latencies.

An 'Aha!' moment precedes the strategic response to a visuomotor rotation Strategic behaviour in sensorimotor adaptation tasks is typically modelled either as an error minimisation process or as a process of learning through trial-and-error. The former predicts a gradual re...

New work led by Max Townsend showing that the strategic response to a visuomotor rotation ('explicit adaptation') is best described as insight learning, rather than gradual error-based or explorative learning.

Visuomotor memory is not bound to visual motion

Early release! We found that visuomotor adaptation transfers across contexts where movement drives oppositely-directed visual motion (cursor moving toward the target vs target moving to the cursor). We believe this says something interesting about theories of internal models

Input device matters for measures of behaviour in online experiments - Psychological Research Studies of perception, cognition, and action increasingly rely on measures derived from the movements of a cursor to investigate how psychological processes unfold over time. This method is one of the...

We demonstrate that cursor movements differ depending on the input device used in online experiments. Given that cursor movements are increasingly used to investigate ongoing perceptual, cognitive, and motoric processes, it is an important variable to consider

Could I be added please?

Could I be added? Thanks.

Sorry to be a pain but it doesn't look like I was added properly.

Please could I be added?

New preprint 📣

We demonstrate that many measures extracted from cursor movements differ between mouse and trackpads. Given input devices typically cannot be controlled in online experiments, it is important to account for this variable.
