Individual Differences In Eyewitness Testimony, Noel A. Cal Jan 2016

Individual Differences In Eyewitness Testimony, Noel A. Cal

Honors Undergraduate Theses

Eyewitness testimony plays a crucial role in the justice system. Misidentification from eyewitnesses was reported in 70% of 300 DNA exonerations of wrongfully convicted individuals (Wixted et al., 2015). Similarly, many convicts can also be set free because of juror’s faulty eyewitness recall during examination. Previous research indicated that females are more reliable in recall than men. However, these findings were not extensively examined with regards to time delay prior to the trial. Thus, it is important to systematically examine the various factors that influence eyewitness testimony.

The present study was designed to empirically examine the effects of gender ...


Music And Memory: A Qualitative Look At How Music Affects Episodic Memory, Jonathan A. Coad Jan 2016

Music And Memory: A Qualitative Look At How Music Affects Episodic Memory, Jonathan A. Coad

Honors Undergraduate Theses

This study was designed to examine qualitative data regarding gender and age differences about significant life events that are recalled when music is remembered. Two groups of participants were recruited, younger adults (M = 19.78, SD = 4.99) and older adults (M = 49.31, SD = 8.72). Data were collected by creating a survey and allowing participants to choose whichever songs, from their own experience, they like and asking them to list detailed memories that are attached to the song. Using the Linguistic Inquiry Word Count (2015) software, data was coded into categories of word count, positive and negative emotions ...


Does Chronic Stress Accelerate Late-Aging Cognitive Decline In Memory And Executive Functioning?, Diane Robinson Jan 2010

Does Chronic Stress Accelerate Late-Aging Cognitive Decline In Memory And Executive Functioning?, Diane Robinson

Electronic Theses and Dissertations

Few studies exist examining the relationship between self-reported stress and cognitive function in healthy nonpsychiatric older adults, and even less studies have examined whether high levels of self-reported stress accelerate the cognitive decline found in normal late-aging populations. A group of older nonpsychiatric adults, ages 54 years and above, were asked to complete three measures assessing their self-perceived stress over the past month, past year, and their lifetime. Sixty-one adults between the ages of 54 and 88 (52% female) participated in a second phase in which neuropsychological tasks were administered to assess three cognitive domains; memory, learning, and executive functioning ...


Adhd Behavior Problems And Near- And Long-Term Scholastic Achievement Differential Mediating Effects Of Verbal And Visuospatial Memory, Dustin E. Sarver Jan 2010

Adhd Behavior Problems And Near- And Long-Term Scholastic Achievement Differential Mediating Effects Of Verbal And Visuospatial Memory, Dustin E. Sarver

Electronic Theses and Dissertations

The current study examined verbal and visuospatial memory abilities as potential mediators of the relationship among ADHD behavior problems and near- and long-term scholastic achievement. Scholastic achievement was measured initially and at 4-year follow-up in an ethnically diverse sample of children (N = 325). Nested composite (reading, math, language) and domain-specific reading structural equation models revealed that ADHD behavior problems exerted a negative influence on scholastic achievement measures, both initially and at follow-up. Much of this influence, however, was mediated by verbal memory’s contribution to near-term achievement, whereas visuospatial memory contributed more robustly to long-term achievement. For the domain-specific math ...


Tactile Working Memory And Multimodal Loading, Peter Terrence Jan 2008

Tactile Working Memory And Multimodal Loading, Peter Terrence

Electronic Theses and Dissertations

This work explored the role of spatial grouping, set size, and stimulus probe modality using a recall task for visual, auditory, and tactile information. The effects of different working memory (WM) loading task modalities were also examined. The Gestalt spatial organizing principle of grouping showed improvements in response times for visual and tactile stimulus probes with large set sizes and apparently allowed participants to effectively chunk the information. This research suggests that tactile information may use spatial characteristics typically associated with visual information, as well as sequential characteristics normally associated with verbal information. Based on these results, a reformulation of ...


Empirical Modeling Of A Marijuana Expectancy Memory Network In Children As A Function Of Age And Marijuana Use, Jacqueline Alfonso Jan 2005

Empirical Modeling Of A Marijuana Expectancy Memory Network In Children As A Function Of Age And Marijuana Use, Jacqueline Alfonso

Electronic Theses and Dissertations

The present investigation modeled the expectancy memory organization and likely memory activation patterns of marijuana expectancies of children across age and marijuana use. The first phase of the study surveyed 142 children to obtain their first associate to marijuana use. From their responses, the Marijuana Expectancy Inventory for Children and Adolescents (MEICA) was developed. The second phase of the study administered the MEICA to a second sample of 392 children to model marijuana expectancy organization and probable memory activation paths of marijuana users versus never-users. Results indicated that irrespective of age, adolescents who have used marijuana tend to emphasize positive-negative ...
