Prior work using word stimuli uncovered evidence that encoding focus (i.e., self-focus or other-focus) altered non-diagnostic recollection and the putative ERP correlate of recollection (i.e., the Late Positive Component, LPC; Leynes & Mok, 2017, Brain & Cognition). The present study examined the generality of these effects by using action stimuli. Participants viewed videos of either a male actor or female actor completing simple actions (e.g., Launch the Rocket; Climb the Stairs). Participants judged how much fun they thought they would have performing the action in the self-focus encoding condition, whereas they rated how much fun the actor had while performing the action in the other-focus encoding condition. At test, participants made source judgments regarding who (i.e., male or female) performed the action. Both the behavioral and ERP data indicated that encoding focus did not affect the amount of diagnostic recollection. Self- and other-focus encoding produced similar recognition and LPC amplitudes. This evidence differs from the effects derived from picture and word stimuli that indicate self-focus encoding increases non-diagnostic recollection. In this study, all actions (regardless of encoding type) promoted strong recollection, which are similar to other demonstrations that depth of encoding manipulations do not affect memory for actions. This is an important boundary condition for self-focus encoding, and it is additional evidence that action memory creates more vivid traces as compared with pictures or words that are typically used in lab-based memory tests.
