“It’S A Choice, Simple As That”: Youth Reasoning For Sexual Abstinence Or Activity, Rochelle L. Dalla

Department of Child, Youth, and Family Studies: Faculty Publications

This investigation was designed to fill gaps in the extant literature by examining reasons give by youth for refraining from or engaging in sexual intercourse, in addition to their perceptions regarding the advantages and disadvantages of premarital intercourse. Quantitative and qualitative data were collected from 103 graduating seniors; 60 self-identified as sexually abstinent and 43 as sexually active. Survey indices were used to assess parent-youth relationships, and parent and peer attitudes toward premarital sex, religiosity, and dating patterns; open-ended questions were used to assess reasons for either engaging in or refraining from sexual intercourse, and to identify benefits and problems …

Effects Of Gregariousness, Conspicuousness, And Novelty On Blue Jay (Cyanocitta Cristata) Learned Avoidance And Stimulus Generalization Of Unpalatable Prey, Joyce M. Dykema

Avian Cognition Papers

I examined a variety of factors hypothesized to be important in the evolution and maintenance of aposematism. Aposematism occurs when prey individuals advertise their toxic or otherwise aversive nature to potential predators via evolved conspicuous signals. I conducted three experiments in which blue jays (Cyanocitta cristata) were allowed to search a printed grayscale pixilated background for grayscale pixilated moths in an open room. I manipulated moth appearance and food reward, and recorded jay predation on the varying moth stimuli. In my first experiment, I repeated Alatalo & Mappes’ (1996) study examining the effects of prey gregariousness, or grouping, …

Measuring Work Preferences: A Multidimensional Tool To Enhance Career Self Management, G. Ronald Gilbert, Ravipreet S. Sohi, Adriana G. Mceachern

Department of Marketing: Faculty Publications

Purpose: The purpose of this paper is to introduce a multidimensional work preference research instrument, and to relate scores on these dimensions with subjects' real world work choices.

Design/methodology/approach: Repeated samples of 1,002 and 975 adult subjects were used to identify 17 empirically derived constructs, using both EFA and CFA statistical applications. The CFA revealed measurement invariance among the predicted and measured constructs. The 17 validated constructs were culled from career development-related psychology that has variously been identified with learning styles, work interests, work values, and temperament. Using a third sample of 590 subjects, MANOVA analyses of work preference scores …

Likelihood Of Using Drug Courts: Predictions Using Procedural Justice And The Theory Of Planned Behavior, Evelyn M. Maeder, Richard L. Weiner

Department of Psychology: Faculty Publications

The current research compares two theoretical models borrowed from social psychology (theory of planned behavior and procedural justice) to predict intentions to make use of a drug court. Medicaid-eligible substance users answered a number of questions regarding their intentions to use a drug court in the future, including items from planned behavior and procedural justice scales. When procedural justice was considered alone, only trustworthiness predicted intention to use drug courts. When planned behavior was considered alone, only deliberative attitudes predicted the intention. After combining the two models, deliberative attitudes from the theory of planned behavior were the only significant predictor …

Occasion-Setting By Drug States: Functional Equivalence Following Similar Training History, Matthew I. Palmatier, Rick A. Bevins

Department of Psychology: Faculty Publications

Three experiments examined whether a drug state serving as a positive feature for pairings between a discrete conditional stimulus (CS, 15-s light or 15-s noise) and sucrose could transfer facilitative control to a CS with which it had never been presented. To do so, a CS was paired with a sucrose reward in the nicotine (0.4 mg/kg), amphetamine (AMP, 1 mg/kg), or chlordiazepoxide (CDP, 5 mg/ kg) drug state; in separate saline sessions the CS was presented but was not followed by any reward. All three drug states facilitated responding to a discrete CS; previous studies found that this facilitation …

Juries And Eyewitnesses, Cindy Laub, Brian H. Bornstein

Department of Psychology: Faculty Publications

The role of an eyewitness can be extremely important in the legal system, as eyewitness testimony and eyewitness identifications play a major role in the prosecution of a criminal defendant. Often the courts are left to rely solely on an eyewitness because there is no other physical evidence. This leaves the jury to rely on a witness’s testimony. Jurors are asked to determine the credibility of an eyewitness at trial when rendering a verdict, and jurors have been found to place more emphasis on eyewitness testimony than on any other kind of evidence. However, there are numerous documented cases of …

Stress And Eyewitness Memory, Ani A. Aharonian, Brian H. Bornstein

Department of Psychology: Faculty Publications

Stress exerts complex effects on eyewitness memory. On the whole, it has a negative effect, but this can be quite variable depending on the level of stress and the aspect of the witnessed event that one is trying to remember. Stress operates similarly in affecting person recognition (i.e., lineup performance) and recall of event details.

Vaccines To Combat Smoking, Rick A. Bevins, Jamie L. Wilkinson, Sam D. Sanderson

Department of Psychology: Faculty Publications

Background—Current U.S. FDA approved biological therapies for treating smoking target central nervous system processes. Although these therapies have had some success, relapse within a year is still high. Clearly additional strategies are needed to aid individuals in maintaining abstinence.

Objective & Methods—We briefly discuss promising research using vaccines to combat smoking and then identify some potentially important directions for future research.

Results & Conclusions—Immunization with a nicotine vaccine generates drug-specific antibodies that sequester some of the nicotine in peripheral circulation preventing it from entering the brain thus decreasing its addictive effects. Albeit promising, much more research is necessary to identify …

Bupropion Differentially Impacts Acquisition Of Methamphetamine Self-Administration And Sucrose-Maintained Behavior, Carmela M. Reichel, Jessica D. Linkugel, Rick A. Bevins

Department of Psychology: Faculty Publications

Bupropion reduces the subjective effects and cue-induced craving for methamphetamine in humans. Given these effects of bupropion on methamphetamine in humans and its widespread clinical use, a preclinical model of drug-taking was used to determine if pretreatment with bupropion would alter the acquisition of methamphetamine self-administration. During acquisition, rats were given saline or bupropion (30 or 60 mg/kg, IP) 5 min before a 60-min session. For the first 8 days, each response on the active lever produced an infusion of methamphetamine (0.025 mg/kg). Responding on the inactive lever had no programmed consequence. This FR1 schedule was then increased to an …

The Pattern Of Subjective Anxiety During In-Session Exposures Across Therapy For Clients With Social Anxiety Disorder, Sarah A. Hayes, Debra A. Hope, Richard G. Heimberg

Department of Psychology: Faculty Publications

Exposure-based therapies have been considered the most efficacious treatments for social anxiety disorder (i.e., Gould et al., 1997). The majority of the theory behind exposure-based treatments rely on Foa and colleagues’s (Foa, Huppert, & Cahill, 2005; Foa & Kozak, 1986) emotional processing theory. However, there has been less research examining the way that emotional processing occurs across actual treatment sessions for clients with social anxiety disorder. This study utilized longitudinal data analytic methods to examine the changes in subjective anxiety during the first three exposure sessions in group and individual cognitive-behavioral therapy for social anxiety disorder. The results of this …

Assessing Client Progress Session By Session In The Treatment Of Social Anxiety Disorder: The Social Anxiety Session Change Index, Sarah A. Hayes, Nathan A. Miller, Debra A. Hope, Richard G. Heimberg, Harlan R. Juster

Department of Psychology: Faculty Publications

Frequent assessment during therapy can improve treatments and provide accountability. However, clinicians often do not monitor progress because of the time it takes to administer and score assessments. In response, the Social Anxiety Session Change Index (SASCI) was developed. The SASCI is a short, easily administered rating of subjective improvement that asks clients with social anxiety disorder how much they have changed since the beginning of therapy. Change on the SASCI was related to change in fear of negative evaluation, a core aspect of social anxiety, and to clinician-rated improvement, but not to ratings of anxiety sensitivity or depression. Because …

Group Treatment In A Community Setting For A Sexually Abused Child And A Non-Offending Caregiver: Case Study And Discussion, Grace S. Hubel, Rosalita C. Maldonado, Poonam Tavkar, David J. Hansen, Mary F. Flood

Department of Psychology: Dissertations, Theses, and Student Research

This study presents the case of an 11-year-old fifth grade female (Amanda) and her mother (Mrs. J) who both completed the Project SAFE (Sexual Abuse Family Education) Group Intervention. Project SAFE is a manualized group treatment for sexually abused children ages 7-16 and their non-offending caregivers developed at the University of Nebraska-Lincoln (Hansen, Hecht, & Futa, 1998), and delivered at a local Child Advocacy Center. Amanda experienced contact sexual abuse by her 39-year-old stepfather on multiple occasions over a 4-year period. Amanda reported symptoms of anxiety, posttraumatic stress, and fear related to the victimization. Mrs. J also reported clinically significant …

Affective Flexibility: Evaluative Processing Goals Shape Amygdala Activity, William A. Cunningham, Jay J. Van Bavel, Ingrid Johnsen Haas

Department of Political Science: Faculty Publications

Although early research implicated the amygdala in automatic processing of negative information, more recent research suggests that it plays a more general role in processing the motivational relevance of various stimuli, suggesting that the relation between valence and amygdala activation may depend on contextual goals. This study provides experimental evidence that the relation between valence and amygdala activity is dynamically modulated by evaluative goals. During functional magnetic resonance imaging, participants evaluated the positive, negative, or overall (positive plus negative) aspects of famous people. When participants were providing overall evaluations, both positive and negative names were associated with amygdala activation. When …
