The Efficacy Of Hippocampal Stimulation In Preventing Depressive Symptoms, Timothy B. Patrick

ETD Archive

The hippocampus provides negative feedback for the Hypothalamic-Pituitary- Adrenal (HPA) axis. The HPA axis is responsible for producing a response to stressful stimuli. The hippocampus is sensitive to high levels of glucocorticoids (GCs), because of its large number of GC receptors. In times of severe stress, hippocampal function is inhibited and its control over the HPA axis is diminished, leading to hyperactivity of the adrenal glands as well as hypercortisolism, typical of depression. Long-term stress and depression can eventually lead to chronic impairments in cognitive ability, as well as structural damage in the hippocampus. Exercise and environmental enrichment stimulate significant …

Examining Whether Social Factors Affect Listeners Sensitivity To Talker-Specific Information During Their Online Perception Of Spoken Words, Jessica L. Newell

ETD Archive

McLennan and Luce (2005) found no significant cost associated with changing which talker produced a particular word from the first block of trials to the second (no talker effects) when participants responded relatively quickly (easy lexical decision), and that talker effects emerged when participants responded relatively slowly (hard lexical decision). In a lexical decision task, participants hear words and nonwords and reaction times to correct responses are measured. In the current study, we examined whether social factors would lead to talker effects in an easy lexical decision task. In Experiment 1, participants were told that they have a chance to …

Perspective Taking In Dyadic Interactions: Influences Of Cooperation And Competition On Third Person Representation Of Movement, Michael H. Summers

ETD Archive

Similar processes between a third person representation and a first person representation may be at work in understanding the limitations of another. These processes may lead to errors in estimating the abilities of another by anchoring those estimates to one's own abilities. A study designed to test how interactive conditions may mediate these processes. It was hypothesized that, due to an increase in interdependence, an individual would show a higher degree of difference between his or her own abilities and those of another when cooperating, compared to non-interactive conditions. It was also hypothesized that competition, due in part to a …

Change Detection Ability In Naturalistic Scenes: Are Object Appearances Or Disappearances Easier To Detect When Disappearances Should Be More Noticeable?, Maria J. Donaldson

ETD Archive

Onset primacy is a robust phenomenon in which appearance of new objects in a scene effectively captures observers' attention. The present study explored conditions under which object offsets may also capture observers' attention. We hypothesized that our visual attentional system is programmed by default to look for onsets of new objects. However, our attentional priority may be able to flexibly adapt to the detection of object offsets depending on what types of visual event better fulfills observers' behavioral goals. To test this hypothesis, an experiment was conducted in which participants were biased toward finding offset of an existing object. Results …

Does Environmental Enrichment While Studying Improve Recall?, Jade-Isis A. Lefebvre, Jordan S. Lefebvre, Lionel G. Standing

Modern Psychological Studies

Previous research suggests that studying audio and visual stimuli in two different rooms increases verbal recall, as compared to studying twice in only one room (Smith, Glenberg, & Bjork, 1978). The present study utilized this paradigm, and also separated the room and modality factors as sources of environmental enrichment. In Experiment 1, subjects learned a list of 40 common English words twice, in either one or two different rooms, and were tested in a third room (N = 60). In Experiment 2, subjects learned the same word lists, using either one or two modalities (audition and vision), and again were …

Pay Attention! Can The Type Of Interaction Between Handler And Dog Preceding An Agility Run Affect A Dog’S Attention During A Run?, Jillian Faustino

Undergraduate Review

There has been an increase of interest in investigating human-dog interactions in recent years. One area of interest for dog owners and animal behaviorists is how interactions and play between humans and dogs affect performance on object choice and detour tasks (Rooney & Bradshaw, 2002, Rooney & Bradshaw, 2003, Schwab & Huber, 2006, Pongracz, Miklosi, Timar-Geng, & Csanyi, 2004, Call, Brauer, Kaminski & Tomasell, 2003). Previous research has suggested that play (a pleasurable game or activity which involves both humans and dogs, such as tug-of-war or fetch) is a very important part in a dog’s social, cognitive and motor development …

Associations Among Types Of Impulsivity, Substance Use Problems And Neurexin-3 Polymorphisms, Scott F. Stoltenberg, Melissa K. Lehmann, Christa C. Christ, Samantha L. Hersrud, Gareth E. Davies

Department of Psychology: Faculty Publications

Background—Some of the genetic vulnerability for addiction may be mediated by impulsivity. This study investigated relationships among impulsivity, substance use problems and six neurexin-3 (NRXN3) polymorphisms. Neurexins (NRXNs) are presynaptic transmembrane proteins that play a role in the development and function of synapses.

Methods—Impulsivity was assessed with the Barratt Impulsiveness Scale Version 11 (BIS-11), the Boredom Proneness Scale (BPS) and the TIME paradigm; alcohol problems with the Michigan Alcoholism Screening Test (MAST); drug problems with the Drug Abuse Screening Test (DAST-20); and regular tobacco use with a single question. Participants (N = 439 Caucasians, 64.7% female) donated buccal cells for …

A Content Analysis Of Indirect, Verbal, And Physical Aggression In Television Programs Popular Among School-Aged Girls, Jennifer Ruh Linder, Kelsey Ann Lyle

Faculty Publications

A content analysis of indirect, verbal, and physical aggression was conducted of 77 hours of television programming popular among fifth grade girls. Eighty-eight percent of programs contained aggression. Physical aggression occurred at a rate of 9.6 acts per hour, whereas indirect and verbal aggression occurred at a rate of 3.7 and 2.8 acts per hour, respectively. Rates of aggression varied by gender, age, and attractiveness of perpetrators, as well as by relationship between perpetrator and victim. Additionally, motivation and consequences of aggressive acts varied by form of aggression. Implications of the findings are discussed in light of current research and …

An Application Of A High-P Low-P Procedure To Improve Recall Memory In Elderly Patients With Mild To Moderate Cognitive Impairment, Dawn Amber Seefeldt

All Graduate Theses, Dissertations, and Other Capstone Projects

Memory problems are a hallmark symptom of dementia. Although memory problems can take various forms, anomia is a common type of cognitive deficit that involves difficulty recalling names of people or objects. The purpose of the current study was to test the effectiveness of two interventions designed to improve the ability to recall the names of objects. Two elderly individuals with memory impairment participated in this study. Baseline involved identifying low and high probability images, with low-probability (low-p) items serving as the target images during the intervention phases. Two interventions were compared using an alternating treatments design. The first intervention, …

The Effects Of Maternal Separation On Alcohol Responses In Adult Mice, Rachel Beckstrom

Undergraduate Honors Theses

Early environmental stressors may play an important role in the development of alcohol abuse and alcoholism in humans. An animal model of early environmental disturbance, termed maternal separation (MS), has been shown to affect alcohol self-administration in adult animals with short periods of daily separation (e.g., 15 min) resulting in lower alcohol intake in adulthood than longer periods of separation (e.g., 180 or 360 min). The current research investigated the possibility that differences in adult alcohol intake following MS may be due, in part, to alterations in alcohol responses independently from the alcohol's reinforcing properties. In particular, the effects of …

Neural Activity, Neural Connectivity, And The Processing Of Emotionally-Valenced Information In Older Adults: Links With Life Satisfaction, Robert J. Waldinger, Elizabeth A. Kensinger, Marc S. Schulz

Psychology Faculty Research and Scholarship

This study examines whether differences in late-life well-being are linked to how older adults encode emotionally-valenced information. Using fMRI with 39 older adults varying in life satisfaction, we examined how viewing positive and negative images affected activation and connectivity of an emotion-processing network. Participants engaged most regions within this network more robustly for positive than for negative images, but within the PFC this effect was moderated by life satisfaction, with individuals higher in satisfaction showing lower levels of activity during the processing of positive images. Participants high in satisfaction showed stronger correlations among network regions – particularly between the amygdala …

Peer Influences On Adolescent Risk Behavior, Dustin Albert, Laurence Steinberg

Psychology Faculty Research and Scholarship

Moving beyond studies of age differences in “cool” cognitive ­processes related to risk perception and reasoning, new approaches to understanding ­adolescent risk behavior highlight the influence of “hot” social and emotional ­factors on adolescents’ decisions. Building on evidence from developmental neuroscience, we present a theory that highlights an adolescent gap in the developmental timing of neurobehavioral systems underpinning incentive processing and cognitive control. Whereas changes in brain regions involved in incentive processing result in heightened sensitivity to social and emotional rewards in early adolescence, cognitive control systems do not reach full maturity until late adolescence or early adulthood. Within this …

Efficacy Of The Jesness Inventory-Revised Conduct Disorder And Oppositional Defiant Disorder Scales, Terry B. Pinsoneault, Frank R. Ezzo

Contemporary Issues in Juvenile Justice

The authors investigated the Conduct Disorder (JR-CD) and Oppositional Defiant Disorder (JR-ODD) scales developed for the Jesness Inventory-Revised. Participants included 340 youth aged 12 to 18 seen at a juvenile court diagnostic clinic in Cleveland, Ohio. The authors also investigated the previously existing Social Maladjustment (JR-SM) and Asocial Index (JR-ASO) scales. Participants were independently diagnosed as having CD, ODD, Disruptive Behavior Disorder NOS (a milder behavioral disorder), or no diagnosable behavioral disorder. Mean scores varied across the groups in the expected directions for all four scales. JR-CD and JR-ODD were better able to differentiate between their target groups and the …

Hardiness As A Predictor Of Success For Marine Corps First Responders In Training, Jason James Bogden

Walden Dissertations and Doctoral Studies

Military personnel and first responders operate in complex operational environments, and must be able to perform under physical, psychological, and emotional stress. Research suggests that resiliency assuages stress and improves the performance of military personnel and first responders. However, there are no studies examining the effects of resiliency on military first responders in training. The purpose of this research was to determine whether the dispositional hardiness traits of commitment, control and challenge displayed by Marine aircraft rescue and firefighting (ARFF) specialist trainees correlated to success in classroom performance, success during practical exercises, higher graduation rates. The theoretical foundation for this …

The Effect Of Positive Verbal Information On Reducing Fears About Bats In School-Aged Children, Kimberly J. Williams

Walden Dissertations and Doctoral Studies

Many school-aged children fear certain animals. Fear tends to make children worry and exhibit anxious behaviors, and this can negatively affect many aspects of their lives. Rachman (1977) speculated that some children might acquire fear through receiving negative verbal information. Few studies have examined whether positive verbal information can influence children's fear beliefs about bats. Based on Rachman's Theory on the Acquisition of Fear Behaviors this experimental research study examined whether positive verbal information might relate to decreasing fears about bats. One hundred and seventy-two participants in Grades 2 through 4 completed the Fear Beliefs Questionnaire (FBQ) and the Bat …

Effects Of 3d Stereoscopy, Visuo-Spatial Working Memory, And Perceptions Of Simulation Experience On The Memorization Of Confusable Objects, Joseph R. Keebler

Electronic Theses and Dissertations

This dissertation investigated the impact of active stereoscopic 3-dimensional (3D) imagery equipment and individual differences in visuo-spatial working memory (VSWM) capacity on retention of a set of similar, novel objects (i.e., armored military vehicles). Seventy-one participants were assessed on their visuo-spatial working memory using the Visual Patterns Test (Della Sala, Gray, Baddeley, & Wilson, 1997). They were then assigned to one of four different conditions (3D high VSWM, 3D low VSWM, 2D high VSWM, 2D low VSWM) based upon their visuo-spatial working memory. Participants were then trained to identify military vehicles using a simulation that presented the training stimuli in …

Verbal Behavior Of Mice And Men: Preference For Multiple Schedules Of Reinforcement As An Indicator Of The Evolution Of Verbal Behavior, Adrianne Eileen Lewis

Psychology Theses - Archive

The evolution of verbal behavior in humans is believed to have appeared in the form of a complex operant behavior. According to behaviorists, the development verbal behavior which is exclusive to Homo sapiens could have been the result of an increased sensitivity to environmental stimuli in the form of another person. Previous animal research by Roark and Kopp (2008) found that sensitivity to environmental stimuli (as indicated by a preference to respond to a multiple schedule of reinforcement) and a preference to respond to additional cues could be a precursor to the evolution of verbal behavior in Sprague Dawley rats. …

An Animal Model Of Conditioned Placebo Analgesia, Christopher T. Mcnabb

Psychology Theses - Archive

Research on placebo analgesia (PA) has called for the further elucidation of underlying neural mechanisms. Animal models allow for experimental manipulations that are not possible or feasible in human research such as brain lesions. Therefore, an animal model would be ideally suited to expand upon human PA literature; however, there is currently no animal model of PA. This study used a classical conditioning paradigm in an effort to induce an analgesic response to placebo treatment in rats. Thirty eight female Sprague-Dawley rats underwent an L5 spinal nerve ligation (L5 SNL) to induce a chronic neuropathic pain condition. Animals were conditioned …

A Tale Of Passion: Linking Job Passion And Cognitive Engagement To Employee Work Performance, Violet Ho, Sze-Sze Wong, Chay Hoon Lee

Management Faculty Publications

We propose a model of job passion that links two types of passion, harmonious and obsessive passion, to employees’ work performance, via the mediating mechanism of cognitive engagement (comprising attention and absorption). Results from a survey conducted with 509 employees from an insurance firm indicate that employees with harmonious passion performed better at work, and that this relationship was mediated primarily by cognitive absorption, that is, the intensity of focus and immersion experienced by the employees when working. However, even though obsessive passion was negatively related to cognitive attention (i.e., the amount of cognitive resources spent thinking about work), it …

The Social Construction Of Self, Kenneth J. Gergen

Psychology Faculty Works

This article evaluates the view that the self is social constructed. It explains that a social constructionist approach to the self is critical insofar as it targets many of the traditional conceptions of self under discussion in this volume. It analyses the primary use of the term self in psychological and mental discourse, suggesting many ways in which the sources of knowledge about the realm of the mental are open to question. It cites the work of Michel Foucault and others who develop a sustained critique of what may be the dark side of the construction of the self as …

Meaning Correlates Of Value Orientations, Shulamith Kreitler

Papers from the International Association for Cross-Cultural Psychology Conferences

The purpose was to explore the relations between value orientations and meaning assignment tendencies. The hypotheses were that values would be related to a certain number of meaning variables that would be similar in three cultural groups. The participants were 150 individuals of both genders living in Israel. They are from three cultural communities (50 participants each): Israeli, French, and Russian. They were administered the values inventory PQ IV by Schwartz (1992) and the Meaning Test by Kreitler and Kreitler (1990a). The relations between the values of hedonism, power, and benevolence and the meaning variables were analyzed by correlations. The …

Wireless Telesurveillance System For Detecting Dementia, William D. Kearns, James L. Fozard, Vilis O. Nams, Jeffrey D. Craighead

Rehabilitation and Mental Health Counseling Faculty Publications

Objective We hypothesized path tortuosity (an index of casual locomotor variability) measured by a movement telesurveillance system would be suitable for assisted living facility residents clinically diagnosed with dementia. Background We examined the relationship of dementia to path tortuosity and to movement speed and path length variability, both of which increase in dementia. Methods Daytime movements of 25 elders (19 female; 14 with dementia; average age 80.6) were monitored for 30 days using radio transponders measuring location with a maximum accuracy of 20 cm. After 30 days, the Mini Mental State Exam (MMSE) and Revised Algase Wandering Scale-Community Version (RAWS-CV) …

Express Yourself: The Effects Of Body Position On Non-Verbal Communication Of Emotions, Kathryn H. Mgrublian

CMC Senior Theses

Recent research has documented that we tend to use the face to express some emotions, but use the body to express other emotions. To understand the contributions of the body to non-verbal emotional communication, we compared the performance of able-bodied participants who were allowed to express emotions naturally (standing) to able-bodied participants who were confined to a wheelchair.  Theories of embodied emotion would predict that restraining the use of the body should change emotion production and communication confidence, especially for body-related emotions. Participants expressed six different emotions in three conditions: 1) naturally, 2) face only, and 3) body only. After …

Attention To Multiple Events Helps 2 1/2-Year-Olds Extend New Verbs, Jane B. Childers

Psychology Faculty Research

An important question in verb learning is how children extend new verbs to new situational contexts. In Study 1, 2 1/2-year-old children were shown a complex event followed by new events that preserved only the action from the initial event, only the result, or no new events. Children seeing events that preserved either the action or the result produced appropriate verb extensions at test while children without this information did not. In a follow-up study, children hearing new verbs produced more extensions than did children hearing nonlabeling speech. These studies suggest that attention to related events is helpful to young …

Submissive And Dominant Sexual Cognitions Of College Women With A History Of Sexual Abuse, Jisun Kelly Park

Masters Theses

The study investigated the effect of timing of sexual abuse on sexual cognitions of submission and dominance. Female college students completed questionnaires containing reports of history of sexual abuse, sex guilt, social desirability, and sexual cognitions. The results show that the childhood and the adulthood abused group have more frequent positive sexual cognitions, more frequent arousal to sexual cognitions, and higher intensity of sexual arousal to these sexual cognitions. The frequency of overall cognitions was the most significant predictor in predicting all submission and dominance sexual cognitions variables. This study while replicating previous findings that survivors of sexual abuse tend …

Anxiety And Visual Discriminations In Undergraduates, Katherine Bowers

The Journal of Undergraduate Research

Mathematics tests were used to create anxiety in undergraduates. Heart rates were recorded as a measure of anxiety. Following each mathematics test, participants completed a different visual discrimination tasks, Stroop Colored Word Tests, Where’s Waldo Puzzles, and IQ Matching Tests. Reaction times and accuracy were measured for each task. The hypothesis was that those with more difficult mathematics tests would have longer reaction times and be less accurate. The results of the study suggest that mathematics anxiety did not have a significant effect on reaction times for any task, and was only significant for the accuracy of the IQ matching …
