Testing The Common-Mechanisms Theory Of False Hearing And False Memory: The Roles Of Executive Functioning And Inhibitory Control, Eric Failes
Arts & Sciences Electronic Theses and Dissertations
Recent studies have shown that older adults are more susceptible to context-based misperceptions in hearing than are younger adults, a phenomenon that has been referred to as false hearing (Rogers et al., 2012; Sommers et al., 2015). The authors of these studies have noted similarities between false hearing and false memories (Jacoby et al., 2005), suggesting that the two phenomena may arise from similar cognitive mechanisms. The present dissertation project investigated similarities between false hearing and false memories. In Experiment 1, I directly compared susceptibility to false hearing and false memories in younger and older adults. I then investigated two …
Apoaequorin Differentially Modulates Fear Conditioning In Adult And Aged Rats, Vanessa Ehlers
Apoaequorin Differentially Modulates Fear Conditioning In Adult And Aged Rats, Vanessa Ehlers
Theses and Dissertations
Normal aging is associated with a number of changes in behavioral and cellular function, and is often linked to increased susceptibility to cognitive impairment. The hippocampus has been widely implicated in learning and memory, and many forms of learning that are hippocampus-dependent (e.g. trace fear conditioning) are impaired in aged animals. A proposed contributor to aging-related cognitive impairment is aging-related calcium (Ca2+) dysregulation. This dysregulation is thought to result from changes in specific Ca2+-regulatory mechanisms, including abnormal Ca2+ ion channel activity or expression, as well as reduced Ca2+-binding protein (CaBP) expression, which is associated with cognitive and synaptic impairment. Previous …
The Effect Of Emotional Faces On The Attentional Blink In Younger And Older Adults, Allison M. Sklenar
The Effect Of Emotional Faces On The Attentional Blink In Younger And Older Adults, Allison M. Sklenar
Masters Theses & Specialist Projects
The attentional blink occurs when detection of a second target (T2) is impaired when it occurs between 180 to 450 ms after the first target (T1) in a rapid serial visual presentation (RSVP). The attentional blink can be affected by relevant emotional stimuli, like emotional faces, such that an emotional T1 enhances the attentional blink, and an emotional T2 attenuates it. However, not all studies use the same type of face stimuli, and there is debate over whether schematic and photo-realistic faces are processed in the same way. Furthermore, the effect of emotion on the attentional blink should differ with …
Strategy Uses And Study Time: Relationship With Memory Performance In Older Adults, Karen A. S. Doolittle
Strategy Uses And Study Time: Relationship With Memory Performance In Older Adults, Karen A. S. Doolittle
Master's Theses - Daytona Beach
The overall purpose of this study was to foster a greater understanding of age-related memory loss as it pertains to the aging workforce's ability to remain productive and effective in a time of complex change, and to recommend some adjustments that can be made to compensate for these memory declines. The specific intent of this current project was to test one premise of Ericsson and Chase's Skilled Memory Theory, namely that memory skill is a skill that can be developed through enhanced encoding and through practice. By introducing participants to the simple mnemonic strategy of chunking and by allowing two …
Age Differences In Bimanual Coordination, Paul Amrhein, George Stelmach, Noreen Goggin
Age Differences In Bimanual Coordination, Paul Amrhein, George Stelmach, Noreen Goggin
Department of Psychology Faculty Scholarship and Creative Works
A bimanual coordination experiment was conducted in which two groups of 10 male and female participants, elderly (67 to 75 years of age) and young (21 to 25 years of age), produced unimanual, bimanual symmetrical (equal extent amplitude), and bimanual asymmetrical (unequal extent amplitude) movements. In addition to an overall increase in performance latency, the elderly group exhibited a linear increase in response initiation (RT) with increases in task complexity similar to that of the young group. However, the elderly participants showed a proportional increase over the young participants in response execution latency (MT). Further, the elderly group had a …
