The Measurement Of Product Typicality In Design Research. A Basic And Applied Approach, Travis Kent

Theses and Dissertations--Psychology

The objective of this study was to examine the use of the cognitive construct of “typicality” to guide design decisions in the development of consumer products. Increasing products that will appeal to consumers, designers strive to balance novelty and familiarity. A potential way to thread this needle is to understand how “typical” a design is of its particular product category. The construct of typicality has been used by psychologists to understand how people create and represent categories. Objects that are more typical of a category are often associated with positive responses from observes (e.g., greater visual appeal, faster recognition). In …

The Interactive Effects Of Brain-Derived Neurotrophic Factor (Bdnf) Polymorphisms And Posttraumatic Stress Disorder On Neurocognitive Functioning In U.S. Military Veterans, Colton Shafer Rippey

Theses and Dissertations--Psychology

Posttraumatic Stress Disorder (PTSD) is associated with mild-to-moderate deficits in neurocognitive functioning. Single nucleotide polymorphisms (SNPs) in the brain-derived neurotrophic factor (BDNF) gene, namely, the Met allele, may also be associated with mild deficits in neurocognitive functioning. However, findings are inconsistent and may be sensitive to environmental epigenetic moderators such as psychopathology.

The current study analyzed data from European-American U.S. military veterans (n = 1,244) who participated in the 2011 National Health and Resilience in Veterans Study (NHRVS). Multivariate analyses of covariances were conducted to evaluate the unique and interactive effects of the Met allele and probable PTSD on …

The Midsession Reversal Task With Pigeons: Effects Of A Brief Delay Between Choice And Reinforcement, Megan Ashley Halloran

Theses and Dissertations--Psychology

During a midsession reversal task, the session begins with a simple simultaneous discrimination in which one stimulus (S1) is correct and the alternate stimulus (S2) is incorrect (S1+/S2-). At the halfway point, the discrimination reverses and S2 becomes the correct choice (S2+/S1-). When choosing optimally, a pigeon should choose S1 until the first trial in which it is not reinforced and then shift to S2 (win-stay/lose-shift). With this task pigeons have been shown to respond suboptimally by anticipating the reversal (anticipatory errors) and continuing to choose S1 after the reversal (perseverative errors). This suboptimal behavior may result from a pigeon’s …

Exploring Illusions Of Height In Suit Design, Michael P. Lee

Theses and Dissertations--Psychology

Objective: The goal of this research was to explore how the design of clothing, specifically the design of the suit, can create height illusions.

Background: Taller people enjoy many advantages, such as increased income and perceived attractiveness. These advantages motivate people to try to appear taller than they actually are, and clothing experts provide advice on how to accomplish this. However, there is little empirical evidence to validate the illusory effects clothing might have on overall height perception. The few studies that have explored illusions of body size created by clothing design have been limited in two important ways – …

Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews

Theses and Dissertations--Psychology

The principle of least effort suggests that animals should minimize effort to reinforcement. Thus, not pecking should be preferred over pecking. However, pigeons often peck when it is allowed but not required (e.g., fixed time schedules) but pecking may be adventitiously reinforced. In the present experiment, to better compare a schedule of reinforcement that requires pecking with one that requires the absence of pecking, we compared a fixed-interval (FI) schedule in which reinforcement follows the first peck after the interval has elapsed and a differential-reinforcement-of-other behavior (DRO) schedule which requires pigeons abstain from pecking for a similar interval. The delay …

Perceptions In Predicting Actor And Partner Sexual And Relational Satisfaction In Couple Relationships, Lucia Novakova

Theses and Dissertations--Family Sciences

The present exploration of perceptual accuracy and bias in romantic relationships bridges a gap in the literature on the ability of partners to estimate one another’s level of relational and sexual satisfaction, and its impact on their own and their partner’s level of satisfaction. A sample of 50 couples, recruited internationally, in continuously monogamous relationships of at least six-months in length completed online assessments of their relationship. The degree of accuracy and bias of their perception was established by comparing actor’s estimates of their partner’s satisfaction with the partner’s actual, self-reported satisfaction scores. The actor-partner interdependence model (APIM; Kenny, Kashy, …

The Mediating Role Of Cognitive Flexibility On The Relationship Between Cross-Race Interactions And Psychological Well-Being, Robert D. Cardom

Theses and Dissertations--Educational, School, and Counseling Psychology

Counseling psychologists are tasked with understanding optimal psychological and cognitive functioning. Recent theoretical predictions (Crisp & Turner, 2011) and growing evidence suggest that cross-race interactions are important ways individuals might improve their cognitive and psychosocial functioning. However, the theoretical predictions from Crisp and Turner have not yet been tested in one model. Further, much of the empirical support for the theoretical predictions has been from studies using 1) undergraduate samples and 2) weak theory-measurement fit.

The present study used an online, community survey (N = 270) to test Crisp and Turner’s (2011) predictions that cognitive flexibility would mediate the …

Cognitive And Behavioral Mechanisms Underlying Alcohol-Induced Risky Driving, Jennifer R. Laude

Theses and Dissertations--Psychology

Alcohol intoxication represents one situation an individual might increase their amount of risk taking when driving. This dissertation is comprised of three studies that investigate the mechanisms by which alcohol increases driver risk-taking. Study 1 examined the effect of alcohol on driver risk-taking using a proxemics approach. The study also tested whether alcohol-induced increases in risky driving co-occurred with pronounced impairment in the driver’s skill. The study also examined whether the most disinhibited drivers were also the riskiest. Indeed, alcohol increased driver risk-taking and impaired driving skill. The study also revealed risky driving can be dissociable from impairing effects on …

The Effects Of Alternate-Line Shading On Visual Search In Grid-Based Graphic Designs, Michael P. Lee

Theses and Dissertations--Psychology

Objective: The goal of this research was to determine whether alternate-line shading (zebra-striping) of grid-based displays affects the strategy (i.e., “visual flow”) and efficiency of serial search. Background: Grids, matrices, and tables are commonly used to organize information. A number of design techniques and psychological principles are relevant to how viewers’ eyes can be guided through such visual works. One common technique for grids, “zebra-striping,” is intended to guide eyes through the design, or “create visual flow” by alternating shaded and unshaded rows or columns. Method: 13 participants completed a visual serial search task. The target was embedded in a …

Emotion, Community Development, And The Physical Environment: An Experimental Investigation Of Measurements, George E. Boone

Theses and Dissertations--Community & Leadership Development

A wide range of research fields have studied how emotions and behavior are affected by the physical environment. This gestalt theorist approach of experimental research as well seeks to measure emotion (using the valence-arousal scale) and micro-scale community development interactions when weighted physical environment factors are adjusted. Community development (CD) interactions at the micro-scale have received but slight attention from scholars in the CD research field and this study aims partially to investigate developing objective measures from social observations. CD interactions from recordings along with self-reported emotion through surveys in four quasi-experimental groups (where the environments were constructed based on …
