Abstract: | Negative priming (NP) occurs when responses are slower because the targets were distractors on the preceding trial. Word-naming
NP occurs only with words that have been presented repeatedly as targets; novel words do not show NP. The activation-inhibition
explanation is that representations of repeated-word distractors are activated already and must be inhibited; the inhibition
carries over to the next trial. If this explanation is correct, novel-word NP should occur if the word is semantically primed
(thus activating its representation) before it occurs as a distractor. In two experiments, there was NP for words from a repeated
set, and the magnitude of NP increased when the same word could occur as a target on consecutive trials. There was positive,
rather than negative, priming for novel-word targets that had been semantically primed as distractors. Either the activation
from semantic priming was not sufficiently strong to require inhibition, or the activation-inhibition hypothesis does not
refer to activation of conceptual representations. |
