contextual semantic priming task TASK

Unreviewed

This task presents blocks of fixation and words, with the words varying in the degree to which they are predictable (given the context of the previous words). On each trial, a fixation cross is presented followed by a visual prompt (asterisk) and a sequence of five centrally presented words (in lower case). The experimental variable is the predictability of the terminal, target word, represented in four conditions (Congruent == highly predictable,Incongruent == target word is highly predictable, but the prediction was violated by presenting a terminal word that was inappropriate given the context, Scrambled == initial four words did not establish a context for a grammatical sentence and the target word was not predictable, and Letter String == meaningless letter strings of identical consonants as a control). After presentation of the target word, the participant is asked if the sentence is meaningful. The above description was derived from (and full details are available) here: http://www.jneurosci.org/content/34/8/2871.full
