Express Yourself: The Effects Of Body Position On Non-Verbal Communication Of Emotions, Kathryn H. Mgrublian Jan 2011

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 …


Artful Liars: Malingering On The Draw-A-Person Task, Dennis P. Carmody, Angela M. Crossman Jan 2011

Artful Liars: Malingering On The Draw-A-Person Task, Dennis P. Carmody, Angela M. Crossman

Publications and Research

Malingering is a form of deception in which one fakes illness to earn (positive or negative) reinforcement. The purpose of the current research was to explore the ability of naïve participants to malinger distress on a clinical, projective measure (Draw-A-Person; DAP). In two experiments, individuals first drew figures of a man, woman, and self. Then, they imagined they were in a motor vehicle accident and drew the figures again as if they were falsely claiming distress from the accident. In Experiment 1, 65 undergraduates participated and in Experiment 2, 70 undergraduates and 40 high school students participated. The drawings were …


Mechanisms For Decisions About The Future, Jeffrey R. Stevens Jan 2011

Mechanisms For Decisions About The Future, Jeffrey R. Stevens

Jeffrey Stevens Publications

Evolutionary and psychological perspectives on decision making remain largely separate endeavors. The bounded rationality approach integrates these two perspectives by focusing on simple, plausible mechanisms of decision making and the cognitive capacities needed to implement these mechanisms. Decisions about the future provide a class of decisions that lend themselves to a bounded rationality approach. Though many different mechanisms may exist for making decisions about the future, only a subset of these mechanisms actually require a representation of the future. The bounded rationality approach helps focus on the cognitive capacities and decision mechanisms that are necessary for a full understanding of …


Evaluating The Effects Of A Job-Aid For Teaching Visual Inspection Skills To University Students, Candice M. Jostad Jan 2011

Evaluating The Effects Of A Job-Aid For Teaching Visual Inspection Skills To University Students, Candice M. Jostad

Dissertations

Visual inspection is the primary method of data analysis used in behavior analysis. Thus, it is important that behavior analysts have the skills necessary for accurate visual inspection. Research has shown that visual inspection can sometimes be unreliable, which has broad implications for the evaluation of treatment effects using this method. Traditional lectures have been shown to be ineffective in teaching visual inspection skills to a satisfactory level, although improvements in visual inspection have been accomplished using statistical methods and aids such as celeration lines superimposed on graphs. However, these methods are not effective when the aids are removed and …


Learned Attention In Younger And Older Adults, Jared M. Holder Dec 2010

Learned Attention In Younger And Older Adults, Jared M. Holder

Masters Theses & Specialist Projects

A relatively new phenomenon in learning research called highlighting occurs when participants show a seemingly irrational preference to attribute a stronger cue-outcome association to a later presented perfect predictor when it is paired with an imperfect predictor than that of an earlier presented perfect predictor paired with the same imperfect predictor (Kruschke, 1996). Current research suggests that the highlighting effect depends on the ability to learn to shift attention away from an irrelevant cue toward a more relevant cue in order to reduce errors in causal judgment and preserve an earlier formed association (Kruschke, 2003). Much research has suggested that …


The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend Oct 2010

The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes. Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task.


Exploration Of The Relationship Between Moral Judgment Development And Attention, Lauren I. Clark Aug 2010

Exploration Of The Relationship Between Moral Judgment Development And Attention, Lauren I. Clark

Masters Theses & Specialist Projects

Research in moral psychology has focused on understanding what factors assist in the development of moral action and decision making. The purpose of this study was to address whether variability in attention relates to moral judgment development. The reason for exploring moral judgment development was to further explore the research of Thoma and Bebeau (2008) who documented that the moral development scores of college and graduate students has been declining over time, with more college-aged students scoring in the lower levels of moral reasoning. Attention was chosen as a viable topic of research, based on the writings of Carr (2008a) …


Addressing Relationships Among Moral Judgment Development, Narcissism, And Electronic Media And Communication Devices, Meghan M. Saculla Aug 2010

Addressing Relationships Among Moral Judgment Development, Narcissism, And Electronic Media And Communication Devices, Meghan M. Saculla

Masters Theses & Specialist Projects

Recently, Thoma and Bebeau (2008) reported moral judgment developmental trends among various samples of undergraduates and graduates where increases in Personal Interests reasoning and decreases in Postconventional reasoning were observed. In an attempt to explain such trends, they cited recent trends in increased narcissism among college students (Twenge, Konrath, Foster, Campbell, & Bushman, 2008) and also noted that certain types of technological devices (i.e. social networking websites, cell phones, etc.) may have adverse effects social decision-making and self-presentation. The current study, therefore, addresses the relationships among moral judgment development, narcissism, and electronic media and communication devices (EMCD's). Analyses support that …


The Effects Of Cultural Experience And Subdivision On Tapping To Slow Tempi, Sangeeta Ullal Aug 2010

The Effects Of Cultural Experience And Subdivision On Tapping To Slow Tempi, Sangeeta Ullal

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our ability to accurately synchronize with rhythmic patterns is constrained by two factors: temporal length and interval structure. By using strategies such as subdivision, we can improve synchronization accuracy at slow tempos, but our ability to utilize subdivisions is constrained by the nature of interval ratios contained in culture-specific subdivision types. Western music falls within a restricted temporal range and its metrical subdivisions contain simple ratios, but Indian music violates these constraints. The present study examines the effects of culture-specific experience on these constraints. American and Indian listeners were asked to perform synchronous tapping to a stimulus with a slow …


Inferring Rules From Sound: The Role Of Domain-Specific Knowledge In Speech And Music Perception, Aaronell Shaila Matta Aug 2010

Inferring Rules From Sound: The Role Of Domain-Specific Knowledge In Speech And Music Perception, Aaronell Shaila Matta

UNLV Theses, Dissertations, Professional Papers, and Capstones

Speech and music are two forms of complex auditory structure that play fundamental roles in everyday human experience and require certain basic perceptual and cognitive abilities. Nevertheless, when attempting to infer patterns from sequential auditory input, human listeners may use the same information differently depending on whether a sound is heard in a linguistic vs. musical context. The goal of these studies was to examine the role of domain-specific knowledge in auditory pattern perception. Specifically, the study examined the inference of "rules" in novel sound sequences that contained patterns of spectral structure (speech or instrument timbre) and fundamental frequency (pitch). …


Locus Of Control And The Age Difference In Free Recall From Episodic Memory, Paul Amrhein, Judith K. Bond, Derek Hamilton Mar 2010

Locus Of Control And The Age Difference In Free Recall From Episodic Memory, Paul Amrhein, Judith K. Bond, Derek Hamilton

Department of Psychology Faculty Scholarship and Creative Works

The authors investigated the relation of locus of control (LOC) to age differences in free-recall memory performance. Older and younger participants completed P. C. Duttweiler's (1984) Internal Control Index (ICI) and subsequently performed free-recall memory tasks. Compared with the younger participants, the older participants exhibited poorer recall with more intrusions and uncorrected repetition errors as well as reduced categorical clustering. For the older participants with less internal LOC, recall proportion and item-pair associative recall clustering were lower than for the older participants with more internal LOC. By contrast, the younger participants did not exhibit any LOC effects in their recall …


A New Perspective On Visual Word Processing Efficiency, Joseph W. Houpt, James T. Townsend Jan 2010

A New Perspective On Visual Word Processing Efficiency, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

As a fundamental part of our daily lives, visual word processing has received much attention in the psychological literature. Despite the well established perceptual advantages of word and pseudoword context using accuracy, a comparable effect using response times has been elusive. Some researchers continue to question whether the advantage due to word context is perceptual. We use the capacity coefficient, a well established, response time based measure of efficiency to provide evidence of word processing as a particularly efficient perceptual process to complement those results from the accuracy domain.


Investigation Of Working Memory Across Behavioral And Executive Function Variables In Adolescents With Emotional Disturbance, Eleazar Cruz Eusebio Jan 2010

Investigation Of Working Memory Across Behavioral And Executive Function Variables In Adolescents With Emotional Disturbance, Eleazar Cruz Eusebio

PCOM Psychology Dissertations

Newer insights into working memory may have important implications for understanding varying cognitive abilities in adolescents and their corresponding degrees of success and efforts to accomplish real-world goals. It is important to investigate the construct of working memory in relation to academic, behavioral, and emotional success at school for students classified with an Emotionally Disturbance (ED). In the educational system, students are classified as ED, based upon IDEA regulations present within a multiplicity of these cognitive, behavioral, socio-emotional, and academic difficulties. The associated cognitive deficits often involve poor working memory skills thought to be related to frontal lobe processes. Considering …


Investigating Delay In Health Related Decision Making Versus Non-Health Decision Making, Ann Lassiter Edwards Oct 2009

Investigating Delay In Health Related Decision Making Versus Non-Health Decision Making, Ann Lassiter Edwards

Psychology Theses & Dissertations

Health and non-health decision domains were examined to explore the differences in decision domain and delay preferences. Using an existing cognitive theory of delay (Bastardi & Shafir, 1998; Tykocinski & Ruffle, 2003), type of scenario (health vs. nonhealth) was manipulated within subjects with participants receiving three scenarios of each type. Certainty (certain vs. uncertain) and delay choice condition (no delay, delay, one-week delay) were manipulated between subjects. This resulted in a 2 (health) X 2 (certainty) X 3 (delay choice) split-plot factorial design. The dependent measure was the proportion of action responses (deciding to change status quo) across the three …


Attachment: The Antidote To Trauma, Joshua Straub Sep 2009

Attachment: The Antidote To Trauma, Joshua Straub

Faculty Publications and Presentations

Trauma and loss in life are inevitable. And all too often the traumatic experience itself can be enough to paralyze the mental, emotional, and spiritual state of any given person. Unable to interpret the traumatic experience, many instead are left defined by it. Helping clients discern the objective experience and their subjective reactions to it will help free them from the emotions and beliefs that subsequently control their lives. Based on the most relevant attachment theory research and clinical techniques, this workshop teaches the attentional strategies necessary to helping clients overcome trauma.


Stimulus Type, Level Of Categorization, And Spatial-Frequencies Utilization: Implications For Perceptual Categorization Hierarchies, Assaf Harel, Shlomo Bentin Aug 2009

Stimulus Type, Level Of Categorization, And Spatial-Frequencies Utilization: Implications For Perceptual Categorization Hierarchies, Assaf Harel, Shlomo Bentin

Psychology Faculty Publications

The type of visual information needed for categorizing faces and nonface objects was investigated by manipulating spatial frequency scales available in the image during a category verification task addressing basic and subordinate levels. Spatial filtering had opposite effects on faces and airplanes that were modulated by categorization level. The absence of low frequencies impaired the categorization of faces similarly at both levels, whereas the absence of high frequencies was inconsequential throughout. In contrast, basic-level categorization of airplanes was equally impaired by the absence of either low or high frequencies, whereas at the subordinate level, the absence of high frequencies had …


A Pilot Study Of Bibliotherapy To Reduce Alcohol Problems Among Patients In A Hospital Trauma Center, Paul Amrhein, Timothy Apodaca, William R. Miller, Carol R. Schermer Jul 2009

A Pilot Study Of Bibliotherapy To Reduce Alcohol Problems Among Patients In A Hospital Trauma Center, Paul Amrhein, Timothy Apodaca, William R. Miller, Carol R. Schermer

Department of Psychology Faculty Scholarship and Creative Works

Because alcohol use plays a major role in many injuries that require hospital care, there is increasing interest in developing interventions to address alcohol problems among emergency department and trauma center patients. The aim of the current study was to extend past research on brief interventions by investigating the use of a self-help manual to treat problem drinkers in a hospital trauma center. Forty injured patients who were either intoxicated at the time of injury or screened positive for harmful drinking were randomly assigned to receive either a brief assessment and a self-help booklet with no more than 5 minutes …


Attentional Uncertainty In The Stroop Priming Task, Brandy Nicole Johnson May 2009

Attentional Uncertainty In The Stroop Priming Task, Brandy Nicole Johnson

Masters Theses & Specialist Projects

There is extensive evidence that structures in the anterior attentional system (i.e. dorsolateral prefrontal cortex and anterior cingulate) are susceptible to normal aging processes, whereas structural changes in the posterior attentional system are minimal. Using the Stroop priming task, we investigated whether reducing the involvement of the anterior attentional system by pre-cuing the location of the target stimulus would eliminate age differences in interference. Older adults continued to be susceptible to interference when the location cue was ambiguous or invalid, but were less susceptible when the target location of a stimulus was presented with a valid cue.


Comparing The Accuracy Of Performing Digital And Paper Checklists Using A Feedback Package During Normal Workload Conditions In Simulated Flight, William Gene Rantz Apr 2009

Comparing The Accuracy Of Performing Digital And Paper Checklists Using A Feedback Package During Normal Workload Conditions In Simulated Flight, William Gene Rantz

Dissertations

This study examined whether pilots completed airplane digital or paper checklists more accurately when they received post-flight graphic and verbal feedback. Participants were 6 college student pilots with instrument rating. The task consisted of flying flight patterns using a Frasca 241 Flight Training Device which emulates a Cirrus SR20 aircraft. The main dependent variable was the number of checklist items completed correctly per flight. An alternating treatment, multiple baseline design across pairs with reversal, was used. During baseline, the average percent of correctly completed items per flight varied considerably across participants, ranging from 13% to 57% for traditional paper checklists …


The Neuroscientific Study Of The Self: Methodological And Theoretical Challenges, Cynthia J. Najdowski, Samuel E. Winer Jan 2009

The Neuroscientific Study Of The Self: Methodological And Theoretical Challenges, Cynthia J. Najdowski, Samuel E. Winer

Psychology Faculty Scholarship

Neuroscientific research methods, such as brain imaging techniques, have increasingly been applied to social cognitive research efforts and, in particular, to the study of the self. In this essay we discuss the ability of such research to shed light on the emergent, dynamic psychological phenomenon of self. Although neuroscientific tools can be useful for gaining general knowledge about associated underlying structures, a careful consideration of the methodological and theoretical issues discussed herein is necessary to avoid simplifying or reifying the self.


Adaptive Rationality: An Evolutionary Perspective On Cognitive Bias, Martie Haselton, Gregory A. Bryant, Andreas Wilke, David Frederick, Andrew Galperin, Willem E. Frankenhuis, Tyler Moore Jan 2009

Adaptive Rationality: An Evolutionary Perspective On Cognitive Bias, Martie Haselton, Gregory A. Bryant, Andreas Wilke, David Frederick, Andrew Galperin, Willem E. Frankenhuis, Tyler Moore

Psychology Faculty Articles and Research

A casual look at the literature in social cognition reveals a vast collection of biases, errors, violations of rational choice, and failures to maximize utility. One is tempted to draw the conclusion that the human mind is woefully muddled. We present a three-category evolutionary taxonomy of evidence of biases: biases are (a) heuristics, (b) error management effects, or (c) experimental artifacts. We conclude that much of the research on cognitive biases can be profitably reframed and understood in evolutionary terms. An adaptationist perspective suggests that the mind is remarkably well designed for important problems of survival and reproduction, and not …


Examining Neurophysiological Evidence Of Age-Related Interactions Of Sensory And Cognitive Processes During Speech Processing, Cady Kristen Block Oct 2008

Examining Neurophysiological Evidence Of Age-Related Interactions Of Sensory And Cognitive Processes During Speech Processing, Cady Kristen Block

Psychology Theses & Dissertations

The present study sought to examine the contribution of sensory and cognitive factors on speech processing as evidenced by ERP measures and to find support for the Sensory Cognitive Interaction Theory (SCIT) and the Effortfulness Hypothesis in that older adults. who experience sensory deficits with normal aging. must put forth increased effort during early sensory stages of speech processing that may compromise subsequent semantic performance and recall of information. In the present investigation. younger and older adults performed a sentence verification task at low and high presentation levels (PL). Accuracy and response time to sentence verifications were assessed along with …


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) …


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

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

Renée Crown University Honors Thesis 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 …


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.


The Effects Of Acute Nicotine Abstinence On Vigilance And Verbal Memory In Non-Diagnosed Smokers, David W. Ayer Dec 2007

The Effects Of Acute Nicotine Abstinence On Vigilance And Verbal Memory In Non-Diagnosed Smokers, David W. Ayer

Dissertations

Research has shown a differential prevalence of smoking in the schizophrenic population compared to other psychiatric and non-diagnosed populations. The three most commonly investigated reasons for this differential prevalence in schizophrenics are: the self-medication hypothesis, side effects hypothesis, and sociological hypothesis. The self-medication hypothesis which proposes that schizophrenics smoke at a higher rate to ameliorate cognitive deficits is the most substantiated by the research. Of current interest is the possible role of nicotine in improving performance on vigilance and verbal memory, the two areas shown to be most related to impaired social functioning in schizophrenics. It is difficult to make …

Phonological Facilitation Through Translation In A Bilingual Picture-Naming Task, Paul Amrhein, Aimee Knupsky Oct 2007

Phonological Facilitation Through Translation In A Bilingual Picture-Naming Task, Paul Amrhein, Aimee Knupsky

Department of Psychology Faculty Scholarship and Creative Works

We present a critical examination of phonological effects in a picture-word interference task. Using a methodology minimizing stimulus repetition, English/Spanish and Spanish/English bilinguals named pictures in either L1 or L2 (blocked contexts) or in both (mixed contexts) while ignoring word distractors in L1 or L2. Distractors were either phonologically related to the picture name (direct; FISH–fist), or related through translation to the picture name (TT; LEG–milk–leche), or they were unrelated (bear–peach). Results demonstrate robust activation of phonological representations by translation equivalents of word distractors. Although both direct and TT distractors facilitated naming, TT facilitation was more consistent in L2 naming …


Perceived Desirability Of Given Names: Identifying A Relationship Between Given Names And Associated Personality Traits, Ellen D. Parks Apr 2007

Perceived Desirability Of Given Names: Identifying A Relationship Between Given Names And Associated Personality Traits, Ellen D. Parks

Undergraduate Theses and Capstone Projects

This study was designed to determine whether participants would have better recall for names with phonetic properties that matched a paired personality trait. In other words, phonetically attractive names paired with positive traits and phonetically unattractive names paired with negative traits should have higher rates of recall than names whose phonetic properties did not match a paired personality trait, such as phonetically attractive names paired with negative traits or phonetically unattractive names paired with positive traits. Given names were deemed to be phonetically attractive or unattractive based on the number of sonorants (soft consonant sounds such as l, m, n, …


Maintenance Of Visual Stability In The Human Posterior Parietal Cortex, Erik Chang, Tony Ro Feb 2007

Maintenance Of Visual Stability In The Human Posterior Parietal Cortex, Erik Chang, Tony Ro

Publications and Research

Visual stability refers to our stable visuospatial perceptions despite the unstable visual input caused by saccades. Functional neuroimaging results, studies on patients with posterior parietal cortex (PPC) lesions, and single-unit recordings in the lateral intraparietal sulcus of primates indirectly suggest that the PPC might be a potential locus of visual stability through its involvement with spatial remapping. Here we directly explored the role of the PPC in visual stability by applying transcranial magnetic stimulation (TMS) while participants performed a perisaccadic displacement detection task. We show that TMS over the PPC but not a frontal control site alters sensitivity to displacement …
