An Investigation Of Masked Priming Mechanisms In Binary Classification Tasks, Jason Perry Aug 2011

An Investigation Of Masked Priming Mechanisms In Binary Classification Tasks, Jason Perry

Electronic Thesis and Dissertation Repository

The goal of the present research was to examine the nature of masked priming with an emphasis on the influence of stimulus-response (S-R) associations. In Chapter 2, both the magnitude of the category congruence (priming) effect and the nature of the priming distance effect were assessed in two number classification tasks. Participants made either magnitude (i.e., is the target larger or smaller than ‘5’?) or identification judgments (i.e., press one button if the target is a ‘1’, ‘2’, ‘3’ or ‘4’ or the other button if the target is a ‘6’, ‘7’, ‘8’ or ‘9’). Priming distance effects in …


Dissociable And Dynamic Components Of Cognitive Control: A Developmental Electrophysiological Investigation, Matthew Waxer Apr 2011

Dissociable And Dynamic Components Of Cognitive Control: A Developmental Electrophysiological Investigation, Matthew Waxer

Electronic Thesis and Dissertation Repository

One standard task used to investigate the development of cognitive control is the Dimensional Change Card Sort (DCCS). Performance and patterns of brain activity associated with the DCCS show continued age-related advances into early adolescence. According to many theoretical accounts, the DCCS places demands on a single underlying executive control process. Three experiments examined the possibility that the DCCS places demands on multiple control processes that follow distinct developmental trajectories. In Experiment 1, rule switching and conflict processing made orthogonal contributions to DCCS performance. Rule switching was associated with a cue-locked late frontal negativity (LFN) event-related potential (ERP) and conflict …


Causality And Similarity In Autobiographical Event Structure: An Investigation Using Event Cueing And Latent Semantic Analysis, Christopher M. O'Connor Nov 2010

Causality And Similarity In Autobiographical Event Structure: An Investigation Using Event Cueing And Latent Semantic Analysis, Christopher M. O'Connor

Electronic Thesis and Dissertation Repository

The influence of similarity- and causally-based relations on the organization of autobiographical events was investigated using extended strings of related event memories. These strings were elicited using an event cueing paradigm in which participants generated descriptions of memories from their life, which were then presented as cues to subsequent event memories. In Experiment 1, similarity between generated events was investigated using participants’ similarity ratings, Latent Semantic Analysis, and experimenter judgements of shared event properties. For events close together in a string, event owners’ similarity ratings were higher than non-owners’, and non-owners’ ratings were comparable to similarity calculated using LSA. In …
