Examination Of The Cognitive Mechanisms Underlying Evaluative And Semantic Priming Effects By Varying Task Instructions: An Erp Study, Jennifer Hilda Taylor
Examination Of The Cognitive Mechanisms Underlying Evaluative And Semantic Priming Effects By Varying Task Instructions: An Erp Study, Jennifer Hilda Taylor
Open Access Theses & Dissertations
This study examined the cognitive processes that underlie stimulus identification and the activation of attitudes by investigating behavioral and psychophysiological effects in a priming paradigm. Cognitive mechanisms were investigated by examining evaluative and semantic priming effects on behavioral response times, the N400, and LPP event-related potential (ERP) components by varying tasks between-subjects. Participants either completed an evaluative task, a semantic task, or a feature-detection task. It was hypothesized that the behavioral evaluative priming effect would occur in the evaluative task and that the behavioral semantic priming effect would occur in the semantic and feature-detection tasks. The N400 was hypothesized to …

The N400 Erp: Semantic Vs. Evaluative Incongruities, Jennifer Hilda Taylor
Open Access Theses & Dissertations
The objective of this research was to utilize both behavioral (response times) and psychophysiological measures (ERPs - N400 & Pre-response Positivity) to uncover the cognitive mechanism responsible for the evaluative priming effect (spreading activation vs. response competition) by controlling for semantic influences. This research project examined the evaluative incongruity effect by controlling for semantic influences in two separate studies. The first study kept semantic associations among word pairs completely random, while the second study controlled for semantic associations by either pairing words from the same semantic category (e.g., animal-animal) or from different semantic categories (e.g., animal-person). Participants completed an evaluative …
