Background: Post-traumatic stress disorder (PTSD) is a debilitating disorder defined by the onset of intrusive, avoidant, negative cognitive or affective, and/or hyperarousal symptoms after witnessing or experiencing a traumatic event. Previous voxel-based morphometry studies have provided insight into structural brain alterations associated with PTSD with notable heterogeneity across these studies. Furthermore, how structural alterations may be associated with brain function, as measured by task-free and task-based functional connectivity, remains to be elucidated.

Methods: Using emergent meta-analytic techniques, we sought to first identify a consensus of structural alterations in PTSD using the anatomical likelihood estimation (ALE) approach. Next, we generated functional …

Thinking Perspective Profiles As A Predictor Of Intelligence Analysts' Job Performance., Curtis Rasmussen

Walden Dissertations and Doctoral Studies

Empirical research has supported the use of general cognitive ability to predict employee performance; however, studies have accounted for only a fraction of the variance. The current study addressed whether intellectual styles, which describe how individuals habitually acquire and use information, account for a significant portion of the variance in job performance not covered by general cognitive ability. The study followed a quantitative, nonexperimental design with a convenience sample of 77 intelligence analysts from 6 U.S. government agencies and 2 online professional groups. MindTime provided the primary theoretical framework. The International Cognitive Ability Resource, MindTime Profile InventoryTM, and Self-Rated Analytic …

Cross-Cultural Study Of The Predictors Of Learning In Children Ages 11-15 Years Old, Nadina Melina Williams

UNF Graduate Theses and Dissertations

Academic achievement is deemed a significant indicator for a successful future. Cognitive ability, home environment, and metacognition are among the many factors research has posited to contribute to academic achievement and later success (Alloway & Alloway, 2010; Bradley & Caldwell, 1984, Veenman, Wilhelm, & Beishuizen, 2004). The present study examines the relation between cognitive ability (working memory (WM) and nonverbal ability), metacognitive awareness, implicit theories of IQ, home environment (socioeconomic status (SES), home life, and parental involvement in homework), and learning outcomes (grades) in two distinct sample populations. The study used a sample of 11-15-year-olds and their parents from two …

Not Just Noise: Individual Differences In Cognitive Ability And Response Bias, Tina Chen

Doctoral Dissertations

Response bias is a component of decision making that can be defined as the general willingness to respond a certain way. For example, in recognition memory, one can have a response bias towards responding that a test item has been previously studied, or in reasoning, one can have a response bias towards responding that a conclusion is logically valid. However, not all individuals have the same response bias. Indeed, there is some evidence that response bias is a stable cognitive trait in memory that differs across individuals (Kantner & Lindsay, 2012, 2014). One predictor of this trait may be cognitive …

Age Differences In Revision Of Causal Belief, Kristi M. Simmons

Masters Theses & Specialist Projects

Inductive reasoning (IR) requires efficient working memory (WM). Research shows that the prefrontal cortex (PFC) is involved during WM tasks and that PFC functioning declines with age. The ability to comprehend and update text-based information requires an intact PFC and efficient WM and IR. The current study presented a series of messages about the investigation of a warehouse fire to 48 young and 48 older adults. One message contained a piece of misinformation which another message corrected later. It was hypothesized that a memory cue to the misinformation with the correction statement should benefit older adults the most during the …

Artful Liars: Malingering On The Draw-A-Person Task, Dennis P. Carmody, Angela M. Crossman

Publications and Research

Malingering is a form of deception in which one fakes illness to earn (positive or negative) reinforcement. The purpose of the current research was to explore the ability of naïve participants to malinger distress on a clinical, projective measure (Draw-A-Person; DAP). In two experiments, individuals first drew figures of a man, woman, and self. Then, they imagined they were in a motor vehicle accident and drew the figures again as if they were falsely claiming distress from the accident. In Experiment 1, 65 undergraduates participated and in Experiment 2, 70 undergraduates and 40 high school students participated. The drawings were …
