Affective Misattribution Following Memory Decisions Does Not Transfer To Interleaved Items, David Grybinas
Affective Misattribution Following Memory Decisions Does Not Transfer To Interleaved Items, David Grybinas
Arts & Sciences Electronic Theses and Dissertations
The outcomes of memory search appear to have affective consequences. For instance, during recognition memory tests, concluding that a retrieval probe is from a prior study period (‘old’) leads to higher pleasantness ratings for the probe than concluding it is novel (‘new”). Grybinas, Kantner, and Dobbins (2019) explained this and related findings via a Confirmation of Search (COS) hypothesis that assumes that the affective consequences of successful versus failed episodic retrieval are misattributed to probes used to elicit memory search. While these affective misattributions clearly occur for the memory probes themselves (within-item misattribution), social psychological research has previously shown that …
Just Don't Do It!: A Comparison Of Strategies For Reducing Commission Errors In Older And Younger Adults, Emily Streeper
Just Don't Do It!: A Comparison Of Strategies For Reducing Commission Errors In Older And Younger Adults, Emily Streeper
Arts & Sciences Electronic Theses and Dissertations
Prospective memory (PM) commission errors occur when an individual erroneously repeats an intention that is finished and therefore no longer relevant (e.g., accidentally taking a medication one no longer needs to take). Commission errors have been observed in younger and older adults with age exacerbating commission error risk in select conditions. Only one prior study has used the finished paradigm to investigate the use of explicit strategies to reduce commission error rates in older adults. Bugg, Scullin, and Rauvola (2016) found that forgetting practice, an experience-based strategy, minimized commission errors to floor levels but a preparation-based strategy was ineffective. The …
Through The Ear, To The Brain: How Cognitive Aging Impacts Veridical And False Hearing In The Presence Of Misleading Context, Eric Failes
Arts & Sciences Electronic Theses and Dissertations
A consistent finding in the literature (Benichov, Cox, Tun, & Wingfield, 2012; Dubno, Ahlstrom, & Horwitz, 2000; Hutchinson, 1989; Nittrouer & Boothroyd, 1990; Pichora-Fuller, Schneider & Daneman, 1995; Rogers, Jacoby, & Sommers, 2012; Sommers & Danielson, 1999; Wingfield, Aberdeen, & Stine, 1991) is that spoken word identification improves for both older and younger adults following the addition of a meaningful semantic context, but the improvements are typically greater for older adults. However, more recent findings (Jacoby, Rogers, Bishara, & Shimizu, 2012; Rogers, Jacoby, & Sommers, 2012) suggest that, especially under less favorable perceptual conditions, the increased benefits of semantic context …
The Interaction Of Crystallized And Fluid Abilities In Aging And Speech Perception, Avanti Dey
The Interaction Of Crystallized And Fluid Abilities In Aging And Speech Perception, Avanti Dey
Arts & Sciences Electronic Theses and Dissertations
In a series of studies, I examined the degree to which fluid and crystallized abilities contribute to and interact during speech perception. During the aging process, crystallized abilities (e.g., linguistic and word knowledge) are largely preserved, while fluid abilities involved in the online manipulation of information (e.g., working memory and inhibitory control) decline with age. Importantly, these two components are critical for successful speech perception and comprehension. While prior research has proposed that older adults rely on crystallized knowledge to compensate for cognitive deficits in difficult listening conditions, this hypothesis has not been directly tested. Younger and older adults completed …
The Feasibility Of Using Metacognitive Strategy Training To Improve Performance, Foster Participation, And Reduce Impairment Following Neurological Injury, Timothy J. Wolf
Arts & Sciences Electronic Theses and Dissertations
Executive function is central to our ability to learn and participate in everyday life activities and rehabilitation outcomes for individuals with executive dysfunction after neurological injury are poor. The impairments and performance challenges these individuals experience are typically not identified appropriately so they often do not receive adequate rehabilitation and can have significant challenges returning to complex everyday life activities. The vast majority of rehabilitation efforts to support individuals with neurological injuries with executive dysfunction are based on a restoration model that aims to improve cognitive function with the expectation that these gains will translate to everyday life. The available …
Relationship Between Serum Biomarkers And Three-Month Outcomes Following Pediatric Traumatic Brain Injury (Tbi), Alicia Leanne Janos
Relationship Between Serum Biomarkers And Three-Month Outcomes Following Pediatric Traumatic Brain Injury (Tbi), Alicia Leanne Janos
Arts & Sciences Electronic Theses and Dissertations
With more than 475,000 cases annually, traumatic brain injury (TBI) is the leading cause of morbidity and mortality in children. Promising new tools for the prediction of functional outcomes following pediatric TBI are biomarkers of brain injury that can be detected in blood serum. The most commonly studied biomarkers, S100β, neuron-specific enolase (NSE), and myelin basic protein (MBP), have myriad limitations which preclude their use in clinical care. In the present study, serum concentrations of two novel biomarkers of brain injury (i.e., ubiquitin carboxy-terminal hydrolase-L1, UCH-L1; glial fibrillary acidic protein, GFAP) were collected 24 hours following severe TBI in 30 …
The Effect Of Age-Related Declines In Inhibitory Control On Audiovisual Speech Intelligibility, Avanti Dey
The Effect Of Age-Related Declines In Inhibitory Control On Audiovisual Speech Intelligibility, Avanti Dey
All Theses and Dissertations (ETDs)
Audiovisual: AV) speech perception is perception in which both auditory and visual information is available in order to understand a talker, compared to an auditory signal alone, during face-to-face communication. This form of communication yields significantly higher word recognition performance as compared to either sensory modality alone, constituting a general AV advantage for speech perception. Despite an overall AV advantage, older adults seem to receive less benefit from this bimodal presentation than do younger adults. However, there is evidence to suggest that not all age-related deficits in AV speech perception are of a sensory nature, but are also influenced by …
An Investigation Of The Cognitive And Perceptual Mechanisms Involved In Mania-Proneness, Kimberly Mercer
An Investigation Of The Cognitive And Perceptual Mechanisms Involved In Mania-Proneness, Kimberly Mercer
All Theses and Dissertations (ETDs)
The present research investigates the cognitive and perceptual mechanisms involved in mania-proneness. Building on the work of Depue and colleagues: Depue & Iacono, 1989; Depue & Zald, 1993) and Gray: 1994), which identifies links between the Behavioral Activation System: BAS) and the symptoms observed in mania, this research investigates the hypothesis that people who are prone to mania exhibit cognitive and perceptual biases in information processing when presented with achievement-oriented stimuli both at baseline, and after the receipt of a reward. These hypothesized biases were measured via an affective flanker task, a suboptimal priming task, and a judgment task about …
Perception And Nonconceptual Apprehension, Arnon Cahen
Perception And Nonconceptual Apprehension, Arnon Cahen
All Theses and Dissertations (ETDs)
My dissertation articulates and resolves a problem at the heart of debates about how perception guides our actions and deliberations. The problem arises from the independent plausibility but mutual inconsistency of the following theses: * Some perceptions provide us reasons * Only belief-like states provide us reasons * No perception is belief-like I argue that this problem is deeper than has been acknowledged. Simply rejecting any one thesis leads to serious challenges. Nonetheless, I argue that we can unravel the link between having reasons and having belief-like states in a way that explains the initial plausibility of the first thesis. …
