Accuracy Matters For The Benefits Of Sleep After Retrieval Practice, Steven Dessenberger
Accuracy Matters For The Benefits Of Sleep After Retrieval Practice, Steven Dessenberger
Arts & Sciences Electronic Theses and Dissertations
Previous research suggests that while sleep and retrieval practice can each improve memory on their own, their benefits cannot be combined to produce an additive effect unless feedback is given during the initial test. These previous findings would seem to support a retrieval-as-consolidation of the testing effect, which states that the benefits of retrieval are the result of memory consolidation, a process that normally occurs during the sleep cycle. The present study sought to determine whether the retrieval-as-consolidation account held true when initial test accuracy was considered as a factor. Using foreign language word pairs, we examined the combined effects …
Investigating The Relationship Between Gaze Behavior And Audiovisual Benefit Across Various Speech-To-Noise Ratios, Lauren Gaunt
Investigating The Relationship Between Gaze Behavior And Audiovisual Benefit Across Various Speech-To-Noise Ratios, Lauren Gaunt
Arts & Sciences Electronic Theses and Dissertations
Speech perception improves when listeners are able to see as well as hear a talker, compared to listening alone. This phenomenon is commonly referred to as audiovisual (AV) benefit (Sommers et al., 2005). According to the Principle of Inverse Effectiveness (PoIE), the benefit of multimodal (e.g. audiovisual) input should increase as unimodal (e.g. auditory-only) stimulus clarity decreases. However, recent findings contradict the PoIE, indicating that it should be reassessed. One method for investigating the factors that contribute to AV speech benefit is to examine listeners’ gaze behavior with eye tracking. The present study compared young adults’ (N=50) gaze …
The Unique Effects Of Relatively Recent Conflict On Cognitive Control, Jackson Colvett
The Unique Effects Of Relatively Recent Conflict On Cognitive Control, Jackson Colvett
Arts & Sciences Electronic Theses and Dissertations
In tasks such as Stroop, our past experiences with conflict influence our ability to attend to goal-relevant information and ignore irrelevant information. There exists evidence that conflict experiences on at least two timescales affect cognitive control. The “immediate” timescale is evidenced by congruency sequence effects while the “long” timescale is evidenced by list-wide proportion congruence effects. What remains underspecified is whether relatively recent experiences with conflict may also uniquely influence cognitive control and how experiences on different timescales are weighted. The present, pre-registered experiments aimed to assess the role of relatively recent conflict by examining the potential effects of an …
Retrieval Of Past Events During Change Experience Is Associated With Memory For Change, Mary Hermann
Retrieval Of Past Events During Change Experience Is Associated With Memory For Change, Mary Hermann
Arts & Sciences Electronic Theses and Dissertations
A novel theory has emerged that examines how people process and comprehend change. Two experiments examined these theoretical mechanisms used to detect and recollect changes in everyday activities. Participants viewed movies of an actor performing narrative activities across two fictitious days. During the second movie, participants also completed a prediction task in which they were asked to predict what they thought was going to happen next. In Experiment 1, some activities repeated identically across the two days, some were repeated but changed on a critical feature (e.g. waking up to an alarm from a clock or a phone), and …
Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga
Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga
Arts & Sciences Electronic Theses and Dissertations
Academic achievement is crucial to a child’s psychosocial and occupational success (Davaoudzadeh et al., 2015; Margari et al., 2013). In children with sickle cell disease (SCD), a genetic disorder resulting in abnormal hemoglobin and significant neurologic sequelae, poor academic achievement is common (e.g. Wang et al., 2001). Studies of typically-developing children have revealed links between academic achievement and neuropsychological abilities, particularly higher-order executive abilities that are mediated primarily by frontal brain regions (Altemeier et al., 2006; Bull & Scerri, 2001). In children with SCD, there is a wealth of evidence that executive abilities are impaired (Berkelhammer et al., 2007), but …
Isolating Item And Subject Contributions To The Subsequent Memory Effect, Jihyun Cha
Isolating Item And Subject Contributions To The Subsequent Memory Effect, Jihyun Cha
Arts & Sciences Electronic Theses and Dissertations
The subsequent memory effect (SME) refers to the greater brain activation during encoding of subsequently recognized items compared to subsequently forgotten items. Previous literature regarding SME has been primarily focused on identifying the role of specific regions during encoding or factors that potentially modulate the phenomenon. The current dissertation examines the degree to which this phenomenon can be explained by item selection effects; that is, the tendency of some items to be inherently more memorable than others. To estimate the potential contribution of items to SME, I provided participants a fixed set of items during encoding, which allowed me to …
How Specific Is Domain-Specific Slowing? Evidence For A General Form Of A Domain-Specific Mechanism, Cynthia C. Flores
How Specific Is Domain-Specific Slowing? Evidence For A General Form Of A Domain-Specific Mechanism, Cynthia C. Flores
Arts & Sciences Electronic Theses and Dissertations
Faces are special not just because our ability to quickly and accurately process faces is integral for social functioning throughout our lives, but also because faces are considered a unique class of visual stimuli (i.e., faces rely more on holistic processing than objects and there exist specialized, face-specific regions in the brain). Behavioral and neuropsychological research point to face processing as dissociable from other kinds of visuospatial processing. Although there is evidence that neural specificity for faces is retained in older adults, there is also evidence that age-related impairments are greater in face processing, relative to object processing. Using a …
Dissociable Effects Of Monetary, Liquid, And Social Incentives On Motivation Across The Adult Life Span, Jennifer Crawford
Dissociable Effects Of Monetary, Liquid, And Social Incentives On Motivation Across The Adult Life Span, Jennifer Crawford
Arts & Sciences Electronic Theses and Dissertations
Humans are social creatures and, as such, can be motivated by aspects of social life, like approval from others, to guide decision-making in everyday life. Indeed, a common view in the aging literature is that older adults have a stronger orientation towards socioemotional goals or incentives, relative to other incentive modalities, like money, because of changing motivational priorities in older adulthood. In prior work, however, we found that older adults actually showed greater effects of monetary relative to primary (liquid) incentives, suggesting alternative interpretations of impaired motivational integration and/or slower adaptation to incentive conditions. The current study tested these alternatives, …
The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer
The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer
Arts & Sciences Electronic Theses and Dissertations
The goal of the current study was to determine if students who are deaf or hard of hearing (d/hh) would learn more new vocabulary words through the use of retrieval practice than repeated exposure (repeated study). No studies to date have used this cognitive strategy—retrieval practice—with children who are d/hh. Previous studies have shown that children with hearing loss struggle with learning vocabulary words. This deficit can negatively affect language development, reading outcomes, and overall academic success. Few studies have investigated specific interventions to address the poor vocabulary development for children with hearing loss. The current study investigated retrieval practice …
Learning From Past Conflict: Investigating The Time Scale Of Conflict Learning For Cognitive Control Processes, Abhishek Dey
Learning From Past Conflict: Investigating The Time Scale Of Conflict Learning For Cognitive Control Processes, Abhishek Dey
Arts & Sciences Electronic Theses and Dissertations
Conflict-modulated cognitive control accounts posit that control processes adjust attention based on the probability of conflict associated with a given context (e.g., list of items, a particular item within a list, etc.). However, within these accounts, it is not yet fully understood how the control system learns about the probability of conflict. A specific question I address in the present research is how far back does the control system look to learn about the probability of conflict? In other words, what is the time scale of conflict learning for the control system? I use a statistical model recently developed by …
Individual Differences In Verbal And Visuospatial Learning Efficiency, Thomas Spaventa
Individual Differences In Verbal And Visuospatial Learning Efficiency, Thomas Spaventa
Arts & Sciences Electronic Theses and Dissertations
There is a great deal of variability in how quickly people learn and how long they remember information. Zerr and colleagues (2018) found a robust and stable relationship between an individual’s rate of learning and the durability of their memory, with faster learners tending to retain more after a delay. The relationship between the rapidity and longevity of learning was characterized as learning efficiency. The present study extends these findings by testing whether learning efficiency generalizes across divergent verbal and visuospatial tasks. An ancillary aim was to assess learning efficiency using a continuous measure that can capture fine-grained individual differences …
Evaluating The Latent Variable Structure Of Episodic Long-Term Memory Abilities, Kyle Featherston
Evaluating The Latent Variable Structure Of Episodic Long-Term Memory Abilities, Kyle Featherston
Arts & Sciences Electronic Theses and Dissertations
I investigated how recall and recognition differ depending on the nature of the memory items and what one is asked to remember about them. Participants were asked to remember lists of various types of verbal items, including words, nonwords, common first names, and the names of common objects in pictures that they viewed, or to remember the contextual information that accompanied those items, including their size, location, color, or font. Immediately following presentation of each list, free recall or recognition tests for items or context were administered. It has been proposed that memory for context, or source memory, differs from …
