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 …

Assessing The Effects Of A Rectangular Rapid-Flashing Beacon On Vehicle Speeds Along A Four-Lane Divided Highway, Michelle Van Wagner Jan 2011

Assessing The Effects Of A Rectangular Rapid-Flashing Beacon On Vehicle Speeds Along A Four-Lane Divided Highway, Michelle Van Wagner

Dissertations

In 2008, nearly 31% of vehicle fatalities were related to failure to adhere to safe vehicle speeds (National Highway Traffic Safety Administration (NHTSA), 2009). Two studies were conducted to evaluate the effects of a Rectangular Rapid-Flashing Beacon (RRFB) triggered by excessive speed on vehicle speed using a combined alternating treatments and reversal design. Experiment 1 assessed the RRFB's impact on speeds as compared to baseline conditions only. Experiment 2 compared the RRFB to two standard beacon configurations. Both experiments were conducted at the same site during approximately the same time period and both employed the same data collection methodology. The …

A Perceptually Based Comparison Of Image Similarity Metrics, Richard Russell, Pawan Sinha Jan 2011

A Perceptually Based Comparison Of Image Similarity Metrics, Richard Russell, Pawan Sinha

Psychology Faculty Publications

The assessment of how well one image matches another forms a critical component both of models of human visual processing and of many image analysis systems. Two of the most commonly used norms for quantifying image similarity are L1 and L2, which are specific instances of the Minkowski metric. However, there is often not a principled reason for selecting one norm over the other. One way to address this problem is by examining whether one metric, better than the other, captures the perceptual notion of image similarity. This can be used to derive inferences regarding similarity criteria the human visual …

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 …

Digit Ratios, Baron-Cohen's Reading The Minds In The Eyes And Dart-Throwing Task, Betul Zora Jan 2011

Digit Ratios, Baron-Cohen's Reading The Minds In The Eyes And Dart-Throwing Task, Betul Zora

Honors Program Theses

There is evidence that high prenatal testosterone and the ratio of the index finger to the ring finger are correlated. There is also evidence that male-typical finger ratios correlate positively with male-typical tasks such as targeting and negatively correlated with female-typical tasks. This study examines the correlation between the digit ratio and the dart throwing task and also the digit ratio and Baron-Cohen’s Reading the Mind in the Eyes test. A different digit ratio, the ratio of the index finger and the ring finger to the pinky is also collected and correlated with both of the other tests. Sometime during …

The Relationship Of Leadership Styles, Context, And Outcomes, Max A. Anawalt Jan 2011

The Relationship Of Leadership Styles, Context, And Outcomes, Max A. Anawalt

CMC Senior Theses

New and experienced leaders sometimes underestimate the importance of the follower and context in their ability to be effective and successful in the long term.  During an organization crisis or in a conflict situation, a leaders’ verbal and nonverbal communication behaviors and an awareness of the contextual factors and followers’ feelings involved may contribute more to long-term effectiveness and success more generally than certain characteristics or type of leadership, even if that style is the prevalent model of leadership within the organization. In theory, every leader should benefit from a greater understanding of the evolving study and theory of leadership …

A Theory Of Mental Credit, Jason Soll Jan 2011

A Theory Of Mental Credit, Jason Soll

CMC Senior Theses

Many philosophical subjects attempt to analyze the basis of human welfare. Theories of desert, distribution of property, and happiness tend to dominate philosophical discourse. Mental credit, which is the mental acquisition of credit for one’s accomplishments and the satisfaction one derives from this credit, is absent from this discourse despite its underlying role in the way people think about their lives. Mental credit is an eternal cognitive good that deserves thoughtful attention and pious decisions for implementation. The following theory of mental credit seeks to serve as a unifying theory for the mental calculations that guide life’s most imperative decisions, …

Performance Under Pressure: The Effect Of Explanatory Style On Sensory-Motor Performance Under Stereotype Threat, William R. Macphail Jan 2011

Performance Under Pressure: The Effect Of Explanatory Style On Sensory-Motor Performance Under Stereotype Threat, William R. Macphail

CMC Senior Theses

Do participants with external attribution styles outperform participants with internal explanatory styles in pressure-filled situations? Explicit-monitoring theory suggests that performance becomes impaired when conscious attention is devoted to performing a task normally carried out by automatic processes. Attributing potential failure to an external source (e.g., blaming a sudden gust of wind for a poor golf shot) can decrease the negative effects of stereotype threat, a social-psychological predicament known to engender feelings of stress similar to those experienced in pressure-filled situations, by preventing explicit monitoring from taking place. The current study examined whether individual differences in attribution style, as measured by …

Mad Enough To See The Other Side: Anger And The Search For Disconfirming Information, Maia J. Young, Larissa Z. Tiedens, Heajung Jung, Ming-Hong Tsai Jan 2011

Mad Enough To See The Other Side: Anger And The Search For Disconfirming Information, Maia J. Young, Larissa Z. Tiedens, Heajung Jung, Ming-Hong Tsai

Research Collection School of Social Sciences

The current research explored the effect of anger on hypothesis confirmation the propensity to seek information that confirms rather than disconfirms one's opinion. We argued that the moving against action tendency associated with anger leads angry individuals to seek out more disconfirming information than sad individuals, attenuating the confirmation bias. We tested this hypothesis in two studies of experimentally primed anger and sadness on the selective exposure to hypothesis confirming and disconfirming information. In Study 1, participants in the angry condition were more likely to choose disconfirming information than those in the sad or neutral condition when given the opportunity …

Investigating Intrinsic And Extrinsic Variables During Simulated Internet Search, Molly M. Liechty, Poornima Madhaven Jan 2011

Investigating Intrinsic And Extrinsic Variables During Simulated Internet Search, Molly M. Liechty, Poornima Madhaven

Psychology Faculty Publications

Using an eye tracker we examined decision-making processes during an internet search task. Twenty experienced homebuyers and twenty-five undergraduates from Old Dominion University viewed homes on a simulated real estate website. Several of the homes included physical properties that had the potential to negatively impact individual perceptions. These negative externalities were either easy to change (Level 1) or impossible to change (Level 2). Eye movements were analyzed to examine the relationship between participants' "stated preferences"[verbalized preferences], "revealed preferences" [actual decisions[, and experience. Dwell times, fixation durations/counts, and saccade counts/amplitudes were analyzed. Results revealed that experienced homebuyers demonstrated a more refined …

Adaptive Memory And Social Influences, Aaron D. Leedy Jan 2011

Adaptive Memory And Social Influences, Aaron D. Leedy

UNF Graduate Theses and Dissertations

Recently, cognitive psychologists have focused their research on the survival aspects of human memory, showing advantages for remembering information encoded for adaptive qualities. When participants rated words related to survival relevance (stranded in grasslands), Nairne et al. (2007) and others found survival processing’s retention superior to many semantic encoding techniques, however, we questioned the global application of survival processing. In the present adaptive memory experiment we used the thematic word list paradigm pioneered by Deese, Rodeiger and McDermott, allowing us to measure false recall of critical items from sets of word lists. To investigate recall differences based on the material …

Effects Of Embodiment On Perceptual And Affective Responses To Infant Crying, Jennifer B. Bisson Dec 2010

Effects Of Embodiment On Perceptual And Affective Responses To Infant Crying, Jennifer B. Bisson

Master's Theses

Three experiments were conducted to investigate how changes in bodily states might be related to perceptions of infant vocalizations. In Study 1, participants were asked to hold a pencil between their lips, mimicking a smile, while listening to infant crying. Although there were no embodied effects for perceptual ratings, results indicated that this manipulation decreased participants’ self-reported, negative affect. In Study 2, participants were played both infant crying and birdsong while exposed to similar embodied manipulations, including activation of muscles related to approach and withdrawal behavior. There were no embodied effects for ratings of crying or for affect. Comparing Study …

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 …

Essences And Transformations In Objects, Animals, And Humans, Alicia Brooke Smith Dec 2010

Essences And Transformations In Objects, Animals, And Humans, Alicia Brooke Smith

Masters Theses & Specialist Projects

Research as to how humans group natural kinds, such as animals, is essential to understanding categorization processes. However, it lacks conventional application and generalization to everyday life. Humans are social beings that encounter a wide array of individuals on a daily basis. In these situations, we are required to consider various properties that make up these people. As Keller (2005) suggests, the way we categorize is shaped by our theories about the world. Therefore, when we determine the rationale behind people’s social categorization processes, we are better able to understand people’s perceptions of their social environment. Moreover, when we conduct …

Predictors Of Recall And Reading Time For Seductive And Nonseductive Text Segments, Ivan V. Ivanov Dec 2010

Predictors Of Recall And Reading Time For Seductive And Nonseductive Text Segments, Ivan V. Ivanov

UNLV Theses, Dissertations, Professional Papers, and Capstones

This correlational study explored how concreteness, relevance, importance, and interestingness related to the recall of seductive details and base text, while controlling for text coherence, and student background knowledge. Previous research has provided evidence for the significant relationship between these variables and the seductive details effect in particular and text recall in general. However, this is the first study to consider all these variables simultaneously. A group of 68 undergraduates read an expository text on lightning formation, performed an immediate test on free recall, and rated each text sentence for concreteness, relevance, importance, and interestingness. A simple regression analysis revealed …

Altering Explicit And Implicit Racial Prejudice Towards African American Males, Veronica A. Glover Dec 2010

Altering Explicit And Implicit Racial Prejudice Towards African American Males, Veronica A. Glover

UNLV Theses, Dissertations, Professional Papers, and Capstones

Researchers tested 281 undergraduates to determine if positive behavior messages about African American males presented during a learning task affected scores on explicit and implicit racial prejudice measures. During the learning task, we manipulated how many positive messages the participant viewed (100 vs. 150 or none) and the amount of African American males these messages applied to (1 vs. 3). Participants who viewed 150 positive messages about one African American male displayed more explicit prejudice than participants in control groups or participants learning 100 messages about one person. Results for the implicit measure indicated that participants who learned about three …

The Effects Of Action, Normality, And Decision Carefulness On Anticipated Regret: Evidence For A Broad Mediating Role Of Decision Justifiability., Jochen Reb, Terry Connolly Dec 2010

The Effects Of Action, Normality, And Decision Carefulness On Anticipated Regret: Evidence For A Broad Mediating Role Of Decision Justifiability., Jochen Reb, Terry Connolly

Research Collection Lee Kong Chian School Of Business

Two distinct theoretical views explain the effects of action/inaction and social normality on anticipated regret. Norm theory (Kahneman & Miller, 1986) emphasises the role of decision mutability, the ease with which one can imagine having made a different choice. Decision justification theory (Connolly & Zeelenberg, 2002) highlights the role of decision justifiability, the perception that the choice was made on a defensible basis, supported by convincing arguments or using a thoughtful, comprehensive decision process. The present paper tests several contrasting predictions from the two theoretical approaches in a series of four studies. Study 1 replicated earlier findings showing greater anticipated …

Situating Spatial Templates For Human-Robot Interaction, John D. Kelleher, Robert J. Ross, Brian Mac Namee, Colm Sloan Nov 2010

Situating Spatial Templates For Human-Robot Interaction, John D. Kelleher, Robert J. Ross, Brian Mac Namee, Colm Sloan

Conference papers

People often refer to objects by describing the object's spatial location relative to another object. Due to their ubiquity in situated discourse, the ability to use 'locative expressions' is fundamental to human-robot dialogue systems. A key component of this ability are computational models of spatial term semantics. These models bridge the grounding gap between spatial language and sensor data. Within the Artificial Intelligence and Robotics communities, spatial template based accounts, such as the Attention Vector Sum model (Regier and Carlson, 2001), have found considerable application in mediating situated human-machine communication (Gorniak, 2004; Brenner et a., 2007; Kelleher and Costello, 2009). …

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.

Anger, Fear, And Escalation Of Commitment, Ming-Hong Tsai, Maia J. Young Sep 2010

Anger, Fear, And Escalation Of Commitment, Ming-Hong Tsai, Maia J. Young

Research Collection School of Social Sciences

Two studies examined how discrete emotions influence escalation of commitment. Study 1 demonstrated that anger was associated with more escalation of commitment than fear in a personnel hiring-appraisal context. In addition, it revealed the mediating effect of risk perception; angry compared to fearful individuals perceived lower risk in their initial decision, which in turn increased the tendency to escalate commitment. Study 2 replicated the pattern of results of Study 1 in a financial decision-making situation. Contrary to conclusions drawn from the results of prior research, the current studies suggest that not all negative emotions alleviate escalation of commitment.

Associations Between Mindfulness And Symptoms Of Anxiety., Leisa L. Wells Aug 2010

Associations Between Mindfulness And Symptoms Of Anxiety., Leisa L. Wells

Electronic Theses and Dissertations

This cross-sectional exploratory study considered the associations between mindfulness and symptoms of anxiety. The participants in this study were 183 undergraduate students at a regional university in the southeastern United States. The general hypothesis was that higher levels of mindfulness would be associated with lower levels of anxiety. Hierarchical multiple regression analyses were used to examine the association between a variety of aspects of mindfulness and symptoms of anxiety while controlling for a variety of demographic and historical variables, including previous experience with meditation. Results suggest that not all aspects of mindfulness were related to anxiety. Of the 12 specific …

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) …

An Examination Of Student-Ahtletes' Perceptions Of Their Academic Abilities, Tiffany Ann White Aug 2010

An Examination Of Student-Ahtletes' Perceptions Of Their Academic Abilities, Tiffany Ann White

Masters Theses & Specialist Projects

A common stereotype in our society is that athletes are not as capable of performing well academically as their non-athlete counterparts; they are “dumb jocks”. Do athletes feel that others have lower expectations of them academically? This is important because previous research in education has shown that expectations play a role in academic achievement (for example, Rosenthal and Jacobson’s Pygmalion effect (1968) and self-fulfilling prophecy research). The current study examined student-athletes’ perceptions of this stereotype. Three areas were addressed: athletes’ perceptions of their peers’ awareness that the student is a student-athlete, perceptions of their instructors and peers academic expectations of …

Knowledge Of Nonsuicidal Self-Injury In Populations That Self-Injure, Darcy Leanne Cates Aug 2010

Knowledge Of Nonsuicidal Self-Injury In Populations That Self-Injure, Darcy Leanne Cates

Masters Theses & Specialist Projects

Archived data was utilized for the present study which examined knowledge about non-suicidal self-injury, or NSSI, in individuals who engage in various degrees of the behavior and those who do not self-injure. Knowledge about NSSI was measured in three groups of respondents: those with no history of self-injurious behavior (no NSSI group), those with more limited experience with NSSI who reported 1-30 incidences of NSSI (limited NSSI group), and those with an extensive history (extensive NSSI group) who reported over 30 incidences of NSSI. To measure knowledge, participants were asked level of agreement with myths and facts about NSSI using …

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 …

Topology In Composite Spatial Terms, John D. Kelleher, Robert J. Ross Aug 2010

Topology In Composite Spatial Terms, John D. Kelleher, Robert J. Ross

Conference papers

People often refer to objects by describing the object's spatial location relative to another object, e.g. the book on the right of the table. This type of referring expression is called a spatial locative expression. Spatial locatives have three major components: (1) the target object that is being located (the book), (2) the landmark object relative to which the target is being located (the table), and (3) the description of the spatial relationship that exists between the target and the landmark (on the right of ). In English spatial relationships are often described using spatial prepositions. The set of English …

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). …
