Exploring Animacy As A Mnemonic Dimension, Joshua Edward Vanarsdall

Open Access Dissertations

There is a great deal of evidence across cognitive science that animacy, or more generally, the features that make up what it means to be a living thing, is a foundational dimension of human cognition. In perception, animates both capture attention (Pratt, Radulescu, Guo, & Abrams, 2010) and are relatively immune to change blindness (New, Cosmides, & Tooby, 2007). Developmental work places the animate-inanimate distinction as one of the first categories children learn (Opfer & Gelman, 2011). Work in neuroscience points toward a fundamental role for animacy in semantic memory (Caramazza & Mahon, 2003), and linguists have identified animacy as …

Recognition Training For Faces Across Age Gaps, William Blake Erickson

Graduate Theses and Dissertations

Face recognition is a problem that has theoretical and applied value. However, the fact of facial aging is rarely addressed in research and unmentioned in the major theories of face recognition. Facial aging also has ramifications for missing persons and fugitive cases, confounding attempts by law enforcement to recover these people whose last known images are years or decades out of date. This dissertation reports three studies aimed at measuring baseline age-gap recognition ability and testing various training regimens designed to increase accuracy rates for this unique kind of recognition task.

Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler

Senior Honors Projects, 2010-2019

Recent psychoacoustic experiments (Böckmann-Barthel et al., 2014; Deike et al., 2012) have re-examined research regarding stream segregation and the build-up effect. Stream segregation is the ability to discern auditory objects within a stream of information, such as distinguishing one voice amongst background noise or an instrument within an orchestra. Initial works examining this topic proposed that auditory information is not immediately distinguished as various streams, but rather that differences accumulate over time, allowing listeners to segregate information following a period of build-up (i.e., the build-up effect); whereas more current findings indicate a build-up period is unnecessary for segregation. This experiment’s …

How Musical Oddballs Warp Psychological Time, Rhimmon Simchy-Gross

Graduate Theses and Dissertations

Oddballs—low-probability, attention-capturing expectancy violations—are judged as longer than non-oddballs, but are temporal intervals that contain oddballs judged as longer than those that do not? In 2 experiments, we tested competing model predictions using a novel and covert measure of subjective duration—musical imagery reproduction. Participants verbally estimated and reproduced with musical imagery repeated, coherent, or incoherent familiar or unfamiliar chord sequences (3.5 s, 7 s, or 12 s) that either did or did not contain dynamic auditory oddballs. Participants verbally estimated repeated chord sequences that contained oddballs as shorter than those that did not, but reproduced with musical imagery incoherent chord …

Seeking Solace: Regret, Grief, Anxiety, Rebecca Schroeder

Honors Projects

Seeking Solace: Regret, Grief, Anxiety is a triptych video and artifact piece inspired by the abstract analysis of my dreams. It recognizes worries held within my subconscious and brings them to life through graphic design, photography, and video. The process of creating provides a new perspective of looking at both art and occupational therapy as methods of solving emotional distress.

I have recorded over 80 of my dreams in the past year. In these dreams, regret, grief, and anxiety are common themes. These themes are represented in three triptychs that cycle through past, present, and future problems. The cycling of …

Variability And Location Of Movement Endpoint Distributions: The Influence Of Instructions For Movement Speed And Accuracy, Abhishek Dey

ETD Archive

An influential theory of motor control predicts that targeted hand movements should be aimed at the target center and that the variability of movement endpoint distributions should fill the target region (Meyer et al., 1988). Because increases in the amount of movement endpoint variability correlates with increases in movement speed (Schmidt et al., 1979), centering the distribution on the target center and expanding variability to the limits of the target boundaries should allow for maximization of movement speed, without the production of movement errors (i.e., target misses). Slifkin and Eder (2016) recently found that those predictions only held over a …

Incremental Strategy-Oriented Feedback Promotes Positive Leadership Perceptions And Feedback Reactions, Lauren Murphy

Undergraduate Honors Thesis Collection

In our lab experiment, participants who received negative strategy-oriented feedback associated with an incremental theory had more positive perceptions of a feedback deliverer and the feedback itself compared to recipients of comfort-oriented feedback associated with an entity theory.
