Are Individual Differences In Media Multitasking Habits Associated With Changes In Brain Activation: An Erp Investigation Of Multitasking And Cognitive Control, Morgan Middlebrooks
Are Individual Differences In Media Multitasking Habits Associated With Changes In Brain Activation: An Erp Investigation Of Multitasking And Cognitive Control, Morgan Middlebrooks
Graduate Theses and Dissertations
As the number of mobile phone users grows, understanding the impact of multiple streams of media on media multitasking and related neural correlates is especially pertinent. This research aims to understand the association between media multitasking tendencies on the neural correlates underlying cognitive control using event-related potentials (ERPs). Specifically, we were interested in the N2 and P3, ERPs that measure neural activation underlying aspects of cognitive control. Based on the literature, we predicted that participants who have high media multitasking scores would show more negative N2 activation and more positive P3 activation than their low media multitasking counterparts during an …

Open Access Theses & Dissertations
The effect of stimulus type on task-irrelevant evaluative categorization was examined in two separate studies by using the P3 component from event-related brain potentials. The first study presented idiosyncratic stimuli consisting of individuals that were rated by participants as either positive or negative within sequences of pictorial and verbal stimuli. The second study presented sequences of novel and familiar stimuli consisting of previously normed unattractive and neutral individuals. It was hypothesized that pictures would elicit task-irrelevant evaluative categorization processes and so would novel stimuli (relative to words and familiar stimuli, respectively). Task-irrelevance was examined by assessing P3 peak amplitude to …

Numerous discoveries regarding stereotypes have been uncovered by utilizing techniques and methods developed by cognitive psychologists. The present study continues this tradition by borrowing psychophysiological techniques used for the study of memory and language, and applying them to the study of stereotypes. In this study, participants were primed with either the gender category ’Women’ or ’Men’, followed by a word which was either consistent with gender stereotypes (e.g. Women: Nurturing) or inconsistent (e.g. Women: Aggressive). Their task was to indicate whether the words matched or did not match, according to gender stereotypes. Both response times and event-related brain potentials (ERPs) …
Attitudes To The Right: Evaluative Processing Is Associated With Lateralized Late Positive Event-Related Brain Potentials, John T. Cacioppo, Stephen L. Crites, Wendy L. Gardner
Attitudes To The Right: Evaluative Processing Is Associated With Lateralized Late Positive Event-Related Brain Potentials, John T. Cacioppo, Stephen L. Crites, Wendy L. Gardner
Stephen L Crites Jr.
The authors recently developed a paradigm to investigate the evaluative categorization stage of attitudes using event-related brain potentials (ERPs). The present series of 5 studies with a total of 118 Ss extended this approach by analyzing the spatial topography of the ERP over the lateral scalp region to address complementary questions regarding the nature of operations underlying the evaluative categorization stage of attitude processing. Consistent with the hypothesis that evaluative categorizations engage mechanisms associated with hedonic or global language processing, results revealed that the standardized amplitudes of the late positive potential of the ERP during evaluative categorization were larger over …
Electrocortical Differentiation Of Evaluative And Nonevaluative Categorizations, Stephen L. Crites, John T. Cacioppo
Electrocortical Differentiation Of Evaluative And Nonevaluative Categorizations, Stephen L. Crites, John T. Cacioppo

The evaluative categorizations that underlie affective and attitudinal judgments have often been equated with nonevaluative categorizations despite the central importance of evaluative processes for survival. In the present experiment, a late positive potential (LPP) of the event-related brain potential elicited when participants evaluatively categorized food items as positive or nonpositive was compared with the LPP elicited when participants semantically (i.e., nonevaluatively) categorized food items as vegetable or nonvegetable. Results revealed that evaluative categorizations evoked an LPP that was relatively larger over the right than the left scalp regions compared with the LPP evoked by nonevaluative categorizations. This finding provides evidence …
