title: Directional scanning or reporting preferences are not the cause of visual hemifield x report interactions.
abstract: Young, Bion and Ellis (1980) and Young and Bion (1981) suggested that findings of visual hemifield x report interactions in the naming of bilaterally presented line drawings reflect cerebral hemisphere differences in ability to effect the temporary storage needed when an identified drawing must be reported second. This interpretation has been questioned on the grounds that such a result could also arise from a preference for left to right over right to left scanning or reporting of stimuli. This directional preference account is shown to be untenable because when subjects fixate to one side of both members of horizontal pairs of drawings there is no sign of the (left or right) drawing position x report interaction that it predicts.
