Examining The Time Course Of Indexical Specificity Effects In Spoken Word Recognition, Conor T. Mclennan, Paul A. Luce

Psychology Faculty Publications

Variability in talker identity and speaking rate, commonly referred to as indexical variation, has demonstrable effects on the speed and accuracy of spoken word recognition. The present study examines the time course of indexical specificity effects to evaluate the hypothesis that such effects occur relatively late in the perceptual processing of spoken words. In 3 long-term repetition priming experiments, the authors examined reaction times to targets that were primed by stimuli that matched or mismatched on the indexical variable of interest (either talker identity or speaking rate). Each experiment was designed to manipulate the speed with which participants processed the …

Implicit Cognition And Dissocative Experiences As Predictors Of Adolescent Substance Use, Susan L. Ames, Steve Sussman, Clyde W. Dent, Alan W. Stacy

CGU Faculty Publications and Research

The present study evaluated the mediating role of implicit cognitive processes in the prediction of alcohol and marijuana use and examined the relationships between dissociative experiences, implicit processes, and sensation seeking in models of drug use and problem experiences. Participants were 467 diverse at-risk adolescents in California. Results from latent variable models revealed that implicit cognition independently predicted alcohol and marijuana use and mediated the predictive effects of sensation seeking on drug use. Dissociative experiences did not predict implicit cognition or drug use in this sample, though this factor was a significant predictor of problem experiences and was positively correlated …

Brighter Noise: Sensory Enhancement Of Perceived Loudness By Concurrent Visual Stimulation, Yoav Arieh, Eric C. Odgaard, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Two experiments investigated the effect of concurrently presented light on the perceived loudness of a low-level burst of white noise. The results suggest two points. First, white noise presented with light tends to be rated as louder than noise presented alone. Second, the enhancement in loudness judgments is resistant to two experimental manipulations: varying the probability that light accompanies sound and shifting from a rating method to a forced choice comparison. Both manipulations were previously shown to eliminate a complementary noise-induced enhancement in ratings of brightness. Whereas noise-induced enhancement of brightness seems to reflect a late-stage decisional process, such as …

The Relationship Between Childbirth Experience And Psychological Functioning In The Postpartum Period, Dena Dian Daniel

Graduate Theses

The purpose of this research is to examine the relationships between the mother's perception of the birth experience, symptoms of the post-traumatic stress, and symptoms of postpartum depression. Sixty-seven participants ranging from 17 to 40 years of age completed a self-report questionnaire containing items from three instruments including the Perception of Birth Scale, the Edinburgh Postnatal Depression Scale, and the Davidson Trauma Scale. The findings reveal a more negative perception of the birth experience is significantly related to a greater frequency and/or. severity of. post- traumatic stress and postpartum depression symptoms following childbirth., These findings support the conclusion that an …

Public Displays Of Affection With Relation To Comfort Levels And Culture, Janice R. T. Bryden

Graduate Theses

To determine the tolerance levels of public displays of affection between males, females, Hispanics, and White Non-Hispanics (Whites), a total of 152 participants completed the Attitudes Toward Public Displays of Affection Inventory. While the hypothesis that males would be significantly more tolerant than females of observing public displays of affection was statistically supported for certain settings and certain levels of affection, overall, results may not be clinically meaningful. The second hypothesis, that there would be a significant difference between Hispanics and Whites and their tolerance levels for watching public displays of affection, was not supported. Overall trends indicate passionately kissing …

Affective Development Of Battered Women Subsequent To Leaving Abusive Partner, Cheryl Harrah

Graduate Theses

The present study consisted of semi-structured interviews of formerly battered women who have been out of the relationship for at least one year. The interviews focused on the women’s narratives concerning their experience leaving the relationship and were coded for affect using an Emotional Adjective Checklist. A total of 10 women were recruited from the campus of The University of Texas of the Permian Basin. While each story was unique, a pattern did emerge whereby the women expressed feelings of fear and relief, followed by depression, numbness, and resolve to survive. Long term emotional consequences of the abuse that persisted …

Varied Definitions Of Risk Related To Sensation Seeking Trait, Pål Ø.U. Dåstol, Britt-Marie Drottz-Sjöberg

RISK: Health, Safety & Environment (1990-2002)

[Excerpt] "Risk judgments seem related to which definitions of risk a person uses. Earlier studies suggest that people who use a "probability" definition of risk give different, and somewhat lower, subjective estimates of risk than those who instead prefer a "consequence" definition. In addition, an "optimistic bias" often can be found, and subjects usually evaluate personal risk systematically lower than risk for people in general."

Predictors Of Social Physique Anxiety In Elite Female Youth Athletes, Jeffrey J. Martin, Hermann J. Engels, John C. Wirth, Kari L. Smith

Kinesiology, Health and Sport Studies

The purpose of this study was to examine predictors of social physique anxiety (SPA). SPA, self-esteem, body-esteem, public body consciousness (PBC) and percent body fat (%BF) were assessed with elite female youth athletes (N = 68) competing in either figure skating, soccer or gymnastics. Stepwise multiple regression analyses, controlling for BF%, accounted for 59% of the variance in SPA. Self-esteem entered first, and BF%, followed by body-esteem and PBC. The psychological variables accounted for 57% of the variance with self-esteem contributing the most (R square change = 45%). Contrary to previous research, BF% did not significantly contribute to SPA. …

Crisis Of Infertility: Effects Of Length Of Treatment On Emotional And Marital Adjustment, Christie L. Markestad

Graduate Theses

Twenty infertile couples participated in the present study to investigate whether infertile couples receiving medical treatment experience changes in their emotional, marital and sexual adjustment as a result of the length of time they have been in treatment. The couples were divided into three groups based on how long they had been seeking medical attention for infertility. The instruments administered were: SCL-90-R (Symptom Checklist), Dyadic Adjustment Scale (DAS) and Index of Sexual Satisfaction (ISS). It was predicted couples who were in the initial stages of treatment would experience increased levels of emotional, marital and sexual distress, however those levels would …

Use Of Visual And Tactile Behaviors By Rats (Rattus Norvegicus) In An Object Discrimination Swimming Task, Todd Wiebers

Journal of the Arkansas Academy of Science

When challenged with a cognitive task, rats demonstrate a behavioral flexibility in use and preference of sensory modalities. The present study describes visual and tactile behaviors used by rats in a two choice object discrimination swimming task. The task was designed to preclude use of other sensory modalities and could not be solved via spatial strategies. Fourteen rats learned to criterion a series of 10 discrimination problems. Rats exhibited three stereotypic visual and two stereotypic tactile behaviors over the course of the study. Data analyses indicated that rats demonstrated these behaviors more frequently as they became more familiar with the …

The Occurrence Of Alexithymia In Children And Adolescents With Posttraumatic Stress Disorder, Michael S. Routh

Graduate Theses

Previous studies of the relationship between alexithymia and posttraumatic stress disorder (PTSD) have utilized samples of combat veterans with PTSD. However, children and adolescents who have experienced trauma and are diagnosed with PTSD exhibit similar or identical symptomology. The current study examined alexithymia in a sample of children and adolescents diagnosed with PTSD. It was hypothesized that the sample, when compared to non-PTSD and control samples, would reveal a significantly greater severity of alexithymia and PTSD. Although overall results were not consistent with previous research, trends of group means supported a relationship between alexithymia and PTSD. 1

Nothing Recedes Like Success - Risk Analysis And The Organizational Amplification Of Risks, William R. Freudenburg

RISK: Health, Safety & Environment (1990-2002)

Professor Freudenburg believes that there is room for improvement in Risk analysis, particularly in drawing on systematic studies of human behavior in the calculation of real, empirical probabilities of failure. The need is argued to be especially acute where technological Risks are associated with low expected probabilities of failure and are managed by human organizations for extended periods of time. This permits complacency to set in.

Effects Of Age On Motor Preparation And Restructuring, Paul Amrhein, Noreen Goggin, George Stelmach

Department of Psychology Faculty Scholarship and Creative Works

Age-related decrements in motor plan restructuring were investigated. In this experiment, older and younger adults performed a discrete aiming task that involved responses that were precued and responses that were modified at the time of an imperative signal. On 75% of the trials, the precue specified the response-stimulus (valid trials) with respect to the movement parameters of the arm (left or right) and direction (toward or away). On the remaining 25% of the trials, the response-stimulus was different from the precue (invalid trials) in that the subject was required to modify a planned movement by changing the arm to be …

Normative Data On The Auditory Memory Test Battery For Ages 9 Through 13 Years, Elisabeth Y. Carter

Dissertations and Theses

Auditory short-term memory (STM) is important for speech and language development and for learning new information presented auditorily. Research has shown that auditory STM ability is of a developmental nature in the 5 through 8 year age range for a variety of auditory stimuli. Many tests and subtests are available to measure auditory STM ability, however one test, the Auditory Memory Test Battery (AMTB) measures auditory memory span and memory for sequence for 5 types of stimuli.

The purpose of this study was to collect normative data on the AMTB scores of normal 9 through 13 year old students and …

Modification Of Aggressive Behavior In An Adolescent Through The Use Of Imagery Therapy, Julie Jackson Underriner

Graduate Theses

This case study explored the effects of using 12 sessions of Guided Affective Imagery (GAI) as advocated by Leuner to diminish aggressive behavior. The subject for the study was a thirteen-year-old female who resides in a group home facility. Overt behavior change was analyzed using the Child Behavior Checklist (CBCL) and' the Direct Observation Form (DOF) in a pretreatment, posttreatment, and delayed posttreatment design. A one-way analysis of variance (ANOVA) of the CBCL revealed no significant change in the subject’s aggressive behaviors. However, the DOF revealed a decrease in the subject’s problem behaviors on three other rating scales and an …

Speech Intelligibility As A Function Of The Propositionality Of Background Noise, Gail Swanstrom

Dissertations and Theses

The purpose of this investigation was to measure the ability of young normal hearing listeners to perceive speech in the presence of a background noise which varies in the relative intensity of its semantic content. The Speech Perception in Noise test was mixed with a two-component competing noise complex in which the narrative-to- speech noise ratio varied in 2 dB increments from -2 dB Na/SpN to +8 dB Na/SpN. These stimuli were presented at an overall +8 dB signal-to-noise ratio to thirty young normal hearing adults through the soundfield system. The differences between the mean error scores and standard deviations …

Role-Taking And Behavior, Jane Wynne Uphoff

Dissertations and Theses

The present study examined the relationship between the cognitive skill of role-or perspective-taking and naturally occurring behavior of behaviorally disordered children. Twenty-six boys, aged five years, nine months to twelve years, two months were tested and observed at their treatment facility. It was predicted that children who could take the perspective of others would prefer peer to adult interaction, would more likely give positive attention to their peers and would be more likely to use effective language than their non perspective-taking peers. These and related hypotheses were examined by observing each participant's interactive behavior for 36 minutes distributed over three …
