This is an exploratory study, with no prespecified hypotheses or predictions. We are primarily interested in determining an "attentional map" of the play area that will guide future studies.
As such, we will analyze the data in several ways and explore multiple potential hypotheses. These analyses include:
* examining reaction time and detection rates for dynamic versus static probes
* creating a "heatmap" on the play area of detection and reaction time as a function of location of presentation and position at detection
* examining detection and reaction time as a function of probe distance from the player
* looking for block-level effects on detection rates or reaction time
