Effects of content and viewing distance on the preferred size of moving images.

abstract：:A series of seven experiments explored search for opaque targets among transparent distractors or vice versa. Static stimuli produced very inefficient search. With moving items, search for an opaque target among transparent distractors was quite efficient while search for transparent targets was less efficient (Experi...
