G. M. Reicher (1969) - Perceptual recognition as a function of meaningfulness of stimulus material
저자: Tiziana Sabetta
1. En quoi consiste son expérimentation ?
1.1. - A visual masking field assumed to erase VIS followed the stimulus display after varius intervals ( VIS = fast-decaying system for storing sensory informations)
1.2. Sperling (1967) argued for a parallel, rather than a serial mode of operation of the SCAN (= Scanning device -> selects information from the VIS )
1.2.1. -his Ss performed better on one particular position of a tachistoscopic display
1.2.1.1. Reiseziele
1.2.2. - also notes that Ss can report the approximate number of items & colors
1.2.2.1. this fact suggests parallel processing
1.3. - tests alternatives the present study measured recognition performance on one or two letters, fours-letter words & four-letter non words
1.3.1. RESULTS of the test: 1) requiring a forced choice between two alternative single letters for all conditions 2) arranging the two response alternatives -> both ( correct & incorrect) alternatives would make a common word
2. Quels résultats trouvent-t-il ?
2.1. 1. Differences between the precue and the non precue conditions for each type of material
2.2. 2. Long duration was better (easier) than the short duration for every S.
2.3. 3. in the non precue condition : performance on 1 word was better than on 1 letter or 1 quadrigram ; Performance on 2 words better than 2 letters
2.4. 4. in precue condition: 8 of 9 Ss did better on the single words than on single letters; Performance on 1 of each type of material was better than on 2 of that; Performance on 2 words was not better than on 2 letters when the critical letter was in the bottom row -> for each stimulus duration
2.4.1. Testers did better in the non-precue condition !
