Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang
Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang
Wayne State University Theses
The medial temporal lobe (MTL) and prefrontal cortex (PFC) are two key brain regions that support episodic memory formation in both children and adults, but the functional developmental of these regions remains unclear. In this study, we investigated the development of neural correlates of episodic memory formation using functional MRI with a subsequent memory paradigm, administered to a cross-sectional sample of 83 children and adults. We found that MTL subregions showed an age-related increase in activation supporting memory formation of complex scenes. In addition, a functionally defined scene-sensitive region in the posterior MTL also showed similar increase and predicted better …

Functional Correlates Of Verbal Working Memory In Healthy Aging And Early Alzheimer's Disease, Michael Adam Sugarman
Wayne State University Theses
Deficits in the working memory system are common in patients diagnosed with Alzheimer's disease (AD). However, little is known regarding the neurobiological basis of this impairment. The current study examined the neurobiological functional correlates of the working memory system in early AD patients and cognitively intact control participants using a word list repetition task performed during positron emission tomography (PET). Compared to a reading control task, both the AD and control groups utilized a network of parietal, frontal, and cerebellar regions while completing the word rehearsal task. However, control participants displayed greater activation in all regions, especially in the parietal …
Threat By Association: Minimal Group Affiliation And Its Outcome For Stereotype Threat, Eric W. Fuller
Threat By Association: Minimal Group Affiliation And Its Outcome For Stereotype Threat, Eric W. Fuller
Wayne State University Theses
Stereotype threat has been shown to be an important cause of performance detriments in various social groups. It has also been theorized that stereotype threat could be applicable to any group so long as the individual believes their performance may reinforce the negative stereotype. The current work attempts to induce stereotype threat in participants believing they belong to an experimentally created and negatively stereotyped group using a minimal group paradigm. Across two studies there did not appear to be significant performance changes typically observed in stereotype threat research. Various cognitive measures and post-performance inquiries did generally support claims that participants …
Lateral Cognitive Processing And Belief Updating, Erin Marie Holcomb
Lateral Cognitive Processing And Belief Updating, Erin Marie Holcomb
Wayne State University Theses
Bias in mental representations and belief systems has been linked to asymmetries in information processing by the two hemispheres in research that uses wide variety of methodologies and participant samples. Also, associations have been drawn between such biases in belief systems and sociopolitical orientation leading to the hypothesis that links can be drawn from lateral processing through cognitive style to social and political orientation. This study sought to examine individual differences in laterality - as assessed via a lateralized semantic priming methodology - and manifestations of rigidity and flexibility in belief updating within a sociopolitical context. Analyses revealed that a …
