31Repetitive saccades benefit memory when executed before retrieval, with greatest effects for 32 episodic memory in consistent-handers . Questions remain including how saccades affect scene 33 memory, an important visual component of episodic memory. The present study tested how 34 repetitive saccades affect working and recognition memory for novel scenes. Handedness 35 direction (left-right) and degree (strong/consistent vs. mixed/inconsistent) was measured by raw 36 and absolute laterality quotients respectively from an 8-question handedness inventory 37 completed by 111 adults. Each then performed either 30 seconds of repetitive horizontal 38 saccades or fixation before or after tasks of scene working memory and scene recognition. 39Regression with criterion variables of overall percent correct accuracy and d-prime sensitivity 40showed that when saccades were made before working memory, there was better overall 41 accuracy as a function of increased direction but not degree of handedness. Subjects who made 42 saccades before working memory also performed worse during subsequent recognition memory, 43 while subjects who fixated or made saccades after the working memory task performed better. 44Saccades made before recognition resulted in recognition accuracy that was better (Cohen's 45 d=0.3729), but not significantly different from fixation before recognition. The results 46 demonstrate saccades and handedness interact to affect scene memory with larger effects on 47 encoding than recognition. Saccades before scene encoding in working memory are detrimental 48to short-and long-term memory, especially for those who are not consistently right-handed, 49while saccade execution before scene recognition does not appear to benefit recognition 50 accuracy. The findings are discussed with respect to theories of interhemispheric interaction and 51 control of visuospatial attention. 52 53 54Running Head: Saccades, Handedness, and Scene Memory
