Arousal, Working Memory, And Conscious Awareness In Contingency Learning, Louise D. Cosand, Thomas M. Cavanagh, Ashley A. Brown, Christopher G. Courtney, Anthony J. Rissling, Anne M. Schell, Michael E. Dawson Dec 2008

Arousal, Working Memory, And Conscious Awareness In Contingency Learning, Louise D. Cosand, Thomas M. Cavanagh, Ashley A. Brown, Christopher G. Courtney, Anthony J. Rissling, Anne M. Schell, Michael E. Dawson

Thomas M. Cavanagh

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not …


Dismantling An Act-Based Intervention For Work Stress: Do Values Really Matter?, Barbara A. Hermann Dec 2008

Dismantling An Act-Based Intervention For Work Stress: Do Values Really Matter?, Barbara A. Hermann

Electronic Theses and Dissertations

Acceptance and Commitment Therapy (ACT), a multi-component intervention within the third-wave of behavioral therapy, has been shown to improve various outcomes in diverse populations and administration formats. This study utilized a dismantling design to investigate whether the values components of an ACT-based intervention for work stress add to the effects of the intervention beyond those of the mindfulness components and to explore possible mediators of change. Expanding beyond existing studies of ACT, a broad range of outcomes were examined pretreatment, post-treatment, and at three follow-up assessments in a small sample (N = 16) of employees of a university in the …


Fitness And Action Monitoring: Evidence For Improved Cognitive Flexibility In Young Adults, Jason R. Themanson, Matthew B. Pontifex, Charles H. Hillman Nov 2008

Fitness And Action Monitoring: Evidence For Improved Cognitive Flexibility In Young Adults, Jason R. Themanson, Matthew B. Pontifex, Charles H. Hillman

Jason R. Themanson, Ph.D

To improve behavior, one must detect errors and initiate subsequent corrective adaptations. This action monitoring process has been widely studied, but little is known about how one may improve this aspect of cognition. To examine the relationship between cardiorespiratory fitness and action monitoring, we recorded the error-related negativity (ERN), an event-related brain potential believed to index action monitoring, as well as post-error behavioral indices of action monitoring from healthy young adults (18–25 years) who varied in cardiorespiratory fitness. These measures were collected during the execution of flanker tasks emphasizing response accuracy or speed to better assess the specificity of any …


Connecting The Dots Within: Creative Performance And Identity Integration, Chi-Ying Cheng, Jeffrey Sanchez-Burks, Fion Lee Nov 2008

Connecting The Dots Within: Creative Performance And Identity Integration, Chi-Ying Cheng, Jeffrey Sanchez-Burks, Fion Lee

Research Collection School of Social Sciences

In two studies drawing from social identity theory and the creative-cognition approach, we found that higher levels of identity integration - perceived compatibility between two social identities - predict higher levels of creative performance in tasks that draw on both identity-relevant knowledge domains. Study 1 showed that Asian Americans with higher identity integration were more creative in developing new dishes using a given set of ingredients, but only when both Asian and American ingredients were available. Study 2 showed that female engineers with higher identity integration were more creative in designing a product, but only when the product was targeted …


Using Social Cognitive Theory To Predict Physical Activity In Inner-City African American School Children, Jeffrey J. Martin, Nate Mccaughtry Oct 2008

Using Social Cognitive Theory To Predict Physical Activity In Inner-City African American School Children, Jeffrey J. Martin, Nate Mccaughtry

Kinesiology, Health and Sport Studies

Researchers using social cognitive theory and employing built environment constructs to predict physical activity (PA) in inner-city African American children is quite limited. Thus, the purpose of our investigation was to evaluate the ability of important social cognitive variables (e.g., self-efficacy) and built environment constructs (e.g., neighborhood hazards) to predict African American children’s PA. Children (N = 331, ages 10–14) completed questionnaires assessing social cognitive theory constructs and PA. Using multiple regression analyses we were able to account for 19% of the variance in PA. Based on standardized beta weights, the best predictors of PA were time spent outside …


Multidimensional Self-Efficacy And Affect In Wheelchair Basketball Players, Jeffrey J. Martin Oct 2008

Multidimensional Self-Efficacy And Affect In Wheelchair Basketball Players, Jeffrey J. Martin

Kinesiology, Health and Sport Studies

In the current study, variables grounded in social cognitive theory with athletes with disabilities were examined. Performance, training, resiliency, and thought control self-efficacy, and positive (PA) and negative (NA) affect were examined with wheelchair basketball athletes (N = 79). Consistent with social cognitive theory, weak to strong significant relationships among the four types of self-efficacy (rs = .22–.78) and among self-efficacy and affect (rs = -.40–.29) were found. Basketball players who were efficacious in their ability to overcome training barriers were also confident in their basketball skills and efficacious in their ability to overcome ruminating distressing thoughts …

The Differential Effects Of Mental Fatigue And Alcohol On Selective Attention, Emily Keller Bloesch Aug 2008

The Differential Effects Of Mental Fatigue And Alcohol On Selective Attention, Emily Keller Bloesch

Masters Theses & Specialist Projects

Decrements in selective attention are a commonly experienced phenomenon that has practical implications for many industries. Two causes of such deficits are mental fatigue and alcohol intoxication, which impair selective attention by decreasing the efficiency of inhibitory processes. The present research examined the effects of these two factors on the selective attention subtest of the Useful Field of View test in both a baseline and an experimental session. Participants in the mental fatigue condition (n = 14) were tested while performing a divided attention task for two hours to induce mental fatigue. Those in the alcohol condition (n = 10) …


Evaluation Of A Progressive Model For Identifying Preferred Stimuli For Children With Developmental Disabilities, Amanda M. Karsten Aug 2008

Evaluation Of A Progressive Model For Identifying Preferred Stimuli For Children With Developmental Disabilities, Amanda M. Karsten

Dissertations

Preference assessments for individuals with disabilities differ along many dimensions, including time requirements for implementation and probability of identifying a hierarchy of relative preferences. Some methods of assessment are also more conducive to use with individuals who exhibit problem behavior or certain prerequisite skills. Inaccurate results and loss of valuable treatment time are among the risks associated with selecting ineffective or unnecessarily lengthy procedures. The purpose of the current investigation was to evaluate a progressive model for conducting preference assessments which incorporates many of the aforementioned considerations. Concurrent-operant reinforcer evaluations were used to verify assessment findings. Based on 17 participants …


An Examination Of Sources Of Instructional Feedback And The Connection With Self Determination Theory And Job Satisfaction, Paige M. Birkholz Jul 2008

An Examination Of Sources Of Instructional Feedback And The Connection With Self Determination Theory And Job Satisfaction, Paige M. Birkholz

Masters Theses & Specialist Projects

This study looked to gain information and detail on seven sources of instructional feedback. Instructor’s utilization and perceived value of those sources were examined, along with fulfillment of psychological needs and present job satisfaction. Instructors from Western Kentucky University (WKU; N = 126) were solicited as participants. An online survey included five different measures.

The first, a Sources of Feedback Questionnaire, was created to examine various sources of instructional feedback utilized by participants (institutional student ratings, consultation with faculty, soliciting feedback from students, self-assessment, self-observation, peer/administrator observation, and team teaching). The second measure, adapted from the Basic Needs Satisfaction questionnaire …


The Relationship Between Valuing Diversity And Implicit Racial Bias: A Construct Validation Study, Rebekka Althouse Gordon Jul 2008

The Relationship Between Valuing Diversity And Implicit Racial Bias: A Construct Validation Study, Rebekka Althouse Gordon

Psychology Theses & Dissertations

Two studies examined the construct validity of valuing diversity in relation to both explicit and implicit racial bias. In the first study, participants completed three measures: the Miville-Guzman Universality-Diversity Scale to measure valuing diversity; the Implicit Association Test to assess implicit racial bias; and the Symbolic Racism 2000 Scale to assess explicit racial bias. Results indicated there was a significant relationship between the valuing diversity and implicit racial bias measures as well as between the valuing diversity and explicit racial bias measures. The explicit and implicit racial bias measures accounted for unique variance in the valuing diversity construct. There was …


The Emerging New Human Being, The Culture-In-The-Self, And Ahp's New Multidimensional Intercultural Initiative, Carroy U. Ferguson Jun 2008

The Emerging New Human Being, The Culture-In-The-Self, And Ahp's New Multidimensional Intercultural Initiative, Carroy U. Ferguson

Carroy U "Cuf" Ferguson, Ph.D.

The emerging New Human Being will need to explore and come to terms with a phenomenon, operating deeply, uniquely, and diversely at a core level of all human beings on the planet. I call this phenomenon the “culture-in-the-Self,” a term coined some years ago by cofounders of Interculture Inc. What we commonly think of as culture is just the surface of this phenomenon, often appearing outwardly in the diverse “forms” of cultural scripts, beliefs, values, behaviors, and customs). I want to call attention to what goes on beneath surface culture(s), and how AHP intends to play a primary role in …


Self-Efficacy Effects On Neuroelectric And Behavioral Indices Of Action Monitoring In Older Adults, Jason R. Themanson, Charles H. Hillman, Edward Mcauley, Sarah M. Buck, Shawna E. Doerksen, Katherine S. Morris, Matthew B. Pontifex Jun 2008

Self-Efficacy Effects On Neuroelectric And Behavioral Indices Of Action Monitoring In Older Adults, Jason R. Themanson, Charles H. Hillman, Edward Mcauley, Sarah M. Buck, Shawna E. Doerksen, Katherine S. Morris, Matthew B. Pontifex

Jason R. Themanson, Ph.D

The relationships between self-efficacy (SE), i.e., beliefs in personal capabilities, and behavioral and neuroelectric (i.e., ERN, Pe) indices of action monitoring were investigated in 40 older adults (13 male) during the completion of a flanker paradigm performed under task conditions emphasizing either accuracy or speed. SE relative to task performance during both conditions was assessed prior to each cognitive task. Results indicated that high-SE older adults exhibited larger ERN and Pe amplitudes compared to low-SE older adults under the accuracy instruction condition. Additionally, a moderating effect of SE on the relationship between ERN and post-error response accuracy was revealed in …


Factors That Affect Performance On Executive Functioning After Coronary Artery Bypass Grafting, Sapna Mahesh Patel Jun 2008

Factors That Affect Performance On Executive Functioning After Coronary Artery Bypass Grafting, Sapna Mahesh Patel

Loma Linda University Electronic Theses, Dissertations & Projects

Research suggests that individuals who undergo coronary artery bypass grafting (CABG) experience declines in neuropsychological functioning post-operatively. This decline has been observed in up to 80% of patients early after surgery, and in up to 30% of patients after six months. Many studies have examined the potential effects of CABG on neuropsychological functioning in general, and numerous studies have found that executive functions are impaired in particular. However, none have examined what factors contribute to observed executive dysfunction after CABG. This study investigated the role of memory functions on executive functions in a selected sample of patients undergoing CABG. This …


Predicting Long-Term Memory In Adult Brain Injury Patients Using Mr Spectroscopy, Herminia De La Rosa-Trujillo Jun 2008

Predicting Long-Term Memory In Adult Brain Injury Patients Using Mr Spectroscopy, Herminia De La Rosa-Trujillo

Loma Linda University Electronic Theses, Dissertations & Projects

Accurate outcome prediction has proven to be somewhat elusive for patients with traumatic brain injury (TBI). The difficulty is due to the sometimes inaccurate methods of prediction currently available. Despite the advances seen in radiological technology, the traditional methods of x-rays, CT scans and MRIs are not always accurately able to predict patient functional outcome. These radiological methods are adequate in determining gross structural anatomical disturbances, however, they unable to detect more diffuse cellular damage believed to be responsible for the functional impairments evidenced in patients sustaining TBI. Magnetic Resonance Spectroscopy (MRS) is an imaging technique which measures brain metabolites …


Emotional Speech Corpus Construction, Annotation And Distribution, Brian Vaughan, Charlie Cullen, Spyros Kousidis, John Mcauley May 2008

Emotional Speech Corpus Construction, Annotation And Distribution, Brian Vaughan, Charlie Cullen, Spyros Kousidis, John Mcauley

Conference papers

This paper details a process of creating an emotional speech corpus by collecting natural emotional speech assets, analysisng and tagging them (for certain acoustic and linguistic features) and annotating them within an on-line database. The definition of specific metadata for use with an emotional speech corpus is crucial, in that poorly (or inaccurately) annotated assets are of little use in analysis. This problem is compounded by the lack of standardisation for speech corpora, particularly in relation to emotion content. The ISLE Metadata Initiative (IMDI) is the only cohesive attempt at corpus metadata standardisation performed thus far. Although not a comprehensive …


The Effect Of Computer-Based Biofeedback On Creativity, Qin Li May 2008

The Effect Of Computer-Based Biofeedback On Creativity, Qin Li

Honors Capstone Projects - All

In recent decades, Psychology has advance empirical studies of creativity, aiming for a better and more concrete understanding of this elusive topic. One branch of these studies investigates creativity’s physiological manifestation in an attempt to isolate underlying neurophysiologic mechanisms involved in creative thinking. These studies, through EEG recording of electrical brain activity, indicated that highly creative individuals tend to express a low arousal state as compared to less creative individuals. This experiment investigates the relationship between induced low arousal and creativity. A computer-based biofeedback game is used to induce low arousal. A multivariate analysis of our data revealed no significant …


Development And Validation Of The Counterfactual Thinking For Negative Events Scale, Tarika Daftary Kapur, Mark S. Rye, Melissa B. Cahoon, Rahan S. Ali Apr 2008

Development And Validation Of The Counterfactual Thinking For Negative Events Scale, Tarika Daftary Kapur, Mark S. Rye, Melissa B. Cahoon, Rahan S. Ali

Department of Justice Studies Faculty Scholarship and Creative Works

We examined the psychometric properties of the newly created Counterfactual Thinking for Negative Events Scale (CTNES) in two studies involving university undergraduates. In Study 1 (N = 634), factor analysis revealed four subscales that correspond with various types of counterfactual thinking: Nonreferent Downward, Other-Referent Upward, Self-Referent Upward, and Nonreferent Upward. The subscales were largely orthogonal and had adequate internal consistency and test–retest reliability. The CTNES subscales were positively correlated with a traditional method of assessing counterfactual thinking and were related as expected to contextual aspects of the negative event, negative affect, and cognitive style. In Study 2 (N …


Cross-Modal Interaction Between Vision And Hearing: A Speed—Accuracy Analysis, Yoav Arieh, Lawrence E. Marks Apr 2008

Cross-Modal Interaction Between Vision And Hearing: A Speed—Accuracy Analysis, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Cross-modal facilitation of response time (RT) is said to occur in a selective attention task when the introduction of an irrelevant sound increases the speed at which visual stimuli are detected and identified. To investigate the source of the facilitation in RT, we asked participants to rapidly identify the color of lights in the quiet and when accompanied by a pulse of noise. The resulting measures of accuracy and RT were used to derive speed-accuracy trade-off functions (SATFs) separately for the noise and the no-noise conditions. The two resulting SATFs have similar slopes and intercepts and, thus, can be treated …


Predicting Physical Activity In Arab American School Children, Jeffrey J. Martin, Nate Mccaughtry, Bo Shen Apr 2008

Predicting Physical Activity In Arab American School Children, Jeffrey J. Martin, Nate Mccaughtry, Bo Shen

Kinesiology, Health and Sport Studies

Theoretically grounded research on the determinants of Arab American children's physical activity is virtually nonexistent. Thus, the purpose of our investigation was to evaluate the ability of the theory of planned behavior (TPB) and social cognitive theory (SCT) to predict Arab American children's moderate-to-vigorous physical activity (MVPA). Children (N = 348, ages 10–14) completed questionnaires assessing the TPB and SCT constructs as well as MVPA. Using multiple regression analyses we were able to account for 9% of the variance in MVPA. Based on standardized beta-weights, variance accounted for, and the significance of F change, we concluded that SCT variables …

Cognitive Techniques As A Means For Facilitating Supervisee Development, Aaron Kindsvatter, Darcy Haag Granello, Dr. Jill D. Duba Mar 2008

Cognitive Techniques As A Means For Facilitating Supervisee Development, Aaron Kindsvatter, Darcy Haag Granello, Dr. Jill D. Duba

Counseling & Student Affairs Faculty Publications

During periods of uncertainty or psychological distress, a supervisee may encounter or develop rigid or unhelpful thinking patterns that could delay development by promoting discouraging realities and experiences. Such cognitive experiences often are so subtle that they occur outside the supervisee's immediate awareness. This article explores how the cognitive model of counseling could be used in supervision as a guide to help the supervisor and supervisee discover and modity negative thought processes.

An individual’s spirituality is shaped and supported by his or her cognitive capacities. The purpose of this study was to investigate the relationship between various cognitive deficits and the spiritual development in individuals who qualified for special education under the category of Specific Learning Disability. Participants were randomly selected through systematic sampling of students and former students of Kellyville Public School who met the criteria. The cognitive deficits were measured by the Woodcock-Johnson III Tests of Cognitive Abilities (2001) or the Woodcock-Johnson Psycho-Educational Battery- R (1989), and spiritual development was measured by the Spiritual Assessment Inventory (2002). The results of …


Attention And Emotion Influence The Relationship Between Extraversion And Neural Response, C. A. Hutcherson, P. R. Goldin, W. Ramel, Kateri Mcrae, J. J. Gross Mar 2008

Attention And Emotion Influence The Relationship Between Extraversion And Neural Response, C. A. Hutcherson, P. R. Goldin, W. Ramel, Kateri Mcrae, J. J. Gross

Psychology: Faculty Scholarship

Extraversion has been shown to positively correlate with activation within the ventral striatum, amygdala and other dopaminergically innervated, reward-sensitive regions. These regions are implicated in emotional responding, in a manner sensitive to attentional focus. However, no study has investigated the interaction among extraversion, emotion and attention. We used fMRI and dynamic, evocative film clips to elicit amusement and sadness in a sample of 28 women. Participants were instructed either to respond naturally (n = 14) or to attend to and continuously rate their emotions (n = 14) while watching the films. Contrary to expectations, striatal response was negatively associated with …

The Deconstruction Of A Study: Toward More Effective Evaluation Of Research Studies In Cognitive Social Psychology, Jose A. Montelongo

Library Scholarship

Information literacy modules produced by academic libraries to facilitate the research process typically use the criteria of relevance, timeliness, reliability, coverage and accuracy to assess the various information resources undergraduate students use to write research reports. These same criteria are applied to the wide spectrum of research sources that may range from popular magazines to research journal articles.

In the field of Cognitive Social Psychology, many research questions necessitate the use of psycholinguistic stimuli (word lists, paired-associates, sentences, stories, etc.) as their treatments. This paper investigates the ability of information literacy modules based on the standards set forth by the …


Evaluating The Relationship Among Clinical Measures Of Working Memory, Benjamin L. Giesbrecht Feb 2008

Evaluating The Relationship Among Clinical Measures Of Working Memory, Benjamin L. Giesbrecht

Faculty Publications - Doctor of Psychology (PsyD) Program

Working memory is a construct that has received considerable attention and undergone significant theoretical evolution in the past 35 years. Nevertheless, agreement upon a definition of the concept has not occurred. Contributing to this disagreement are the many ways the concept is operationalized, as is evidenced across various standardized tests that purport to measure working memory. The present study examined this relationship among the working memory component of popular cognitive tests, including the Wechsler Adult Intelligence Scale Third Edition, Wechsler Memory Scale -Third Edition, Stanford-Binet Intelligence Scale - Fifth Edition, and the Wide Range Assessment of Memory and Learning - …


The Once And Future Information Society, James B. Rule, Yasemin Besen-Cassino Jan 2008

The Once And Future Information Society, James B. Rule, Yasemin Besen-Cassino

Department of Sociology Faculty Scholarship and Creative Works

In the late twentieth century, many social scientists and other social commentators came to characterize the world as evolving into an “information society.” Central to these claims was the notion that new social uses of information, and particularly application of scientific knowledge, are transforming social life in fundamental ways. Among the supposed transformations are the rise of intellectuals in social importance, growing productivity and prosperity stemming from increasingly knowledge-based economic activity, and replacement of political conflict by authoritative, knowledge-based decision-making. We trace these ideas to their origins in the Enlightenment doctrines of Saint Simon and Comte, show that empirical support …


Discrimination Reversal Learning In Capuchin Monkeys (Cebus Apella), Michael J. Beran, Emily D. Klein, Theodore A. Evans, Betty Chan, Timothy M. Flemming, Emily H. Harris, David A. Washburn, Duane M. Rumbaugh Jan 2008

Discrimination Reversal Learning In Capuchin Monkeys (Cebus Apella), Michael J. Beran, Emily D. Klein, Theodore A. Evans, Betty Chan, Timothy M. Flemming, Emily H. Harris, David A. Washburn, Duane M. Rumbaugh

Language Research Center

Learning styles in capuchin monkeys were assessed with a computerized reversal- learning task called the mediationaJ paradigm. First, monkeys were trained to respond with 90% accuracy on a two-choice discrimination (A+B-). Then the authors examined differences in performance on three different types of reversal trials (A-B+, A-C+, B+C-), each of which offered differing predictions for performance, depending on whether the monkeys were using associative cues or rule-based strategies. Performance indicated that the monkeys mainly learned to avoid the B stimulus during training, as the A-C+ condition produced the best performance levels. Therefore, negative stimuli showed greater control over responding after …


Fifty Years Of Memory Of College Grades: Accuracy And Distortions, Harry P. Bahrick, Lynda K. Hall, Laura A. Da Costa Jan 2008

Fifty Years Of Memory Of College Grades: Accuracy And Distortions, Harry P. Bahrick, Lynda K. Hall, Laura A. Da Costa

All Faculty and Staff Scholarship

One to 54 years after graduating, 276 alumni correctly recalled 3,025 of 3,967 college grades. Omission errors increased with the retention interval, and better students made fewer errors. Accuracy of recall increased with confidence in recall. Eighty-one percent of commission errors inflated the actual grade. Distortions occur soon after graduation, remain constant during the retention interval, and are greater for better students and for courses students enjoyed most. Confidence in recall is unrelated to distortion. Courses that were not freely recalled, but had to be cued, were recalled less accurately and with less distortion. The data support a supplementary theory …
