Document Summary

Sperling: is there a limit to the number of things perceived, perception is not a capacity process, does not require attention. Present cue soon enough after stimuli are presented, people perceive all. Showed a bunch of stimuli, presented cue. Made participant report only some of the stimuli and they were successful which means since they didn"t know which stimuli they would be asked, they must attend to all. 4, 8, 12 or 16 stimuli presented. People did worse as number of things increased: i. e. , did worse with 16 than 4. Gardner (1970: sensory memory exp. is too simple perception. Memory: a person perceives everything but we get a roadblock in deciding what was perceived, not limited but unlimited, t/f detection test. Participants were convinced there was neither a t nor an f and that, in fact, they were all hybrids: participants were equally good at the first and second conditions. There is only one decision, perception is unlimited.
