Common And Distinct Mechanisms Of Cognitive Flexibility In Prefrontal Cortex, Chobok Kim, Nathan F. Johnson, Sara E. Cilles, Brian T. Gold
Neuroscience Faculty Publications
The human ability to flexibly alternate between tasks represents a central component of cognitive control. Neuroimaging studies have linked task switching with a diverse set of prefrontal cortex (PFC) regions, but the contributions of these regions to various forms of cognitive flexibility remain largely unknown. Here, subjects underwent functional brain imaging while they completed a paradigm that selectively induced stimulus, response, or cognitive set switches in the context of a single task decision performed on a common set of stimuli. Behavioral results indicated comparable reaction time costs associated with each switch type. Domain-general task-switching activation was observed in the inferior …

The impact of female role models on women’s leadership aspirations and self-perceptions after a leadership task were assessed across two laboratory studies. These studies tested the prediction that upward social comparisons to high-level female leaders will have a relatively detrimental impact on women’s self-perceptions and leadership aspirations compared to male and less elite female leaders. In Study 1 (N = 60), women were presented with both female and male leaders before serving as leaders of ostensible three-person groups in an immersive virtual environment. This study established the relatively deflating impact of high-level female leaders, compared to high-level male leaders and …

Political Information And Emotions In Ethnic Conflict Interventions, Cigdem Sirin, José Villalobos, Nehemia Geva
Selected Works Temporary Series
This study explores the effects of political information and anger on the public’s cognitive processing and foreign policy preferences concerning third-party interventions in ethnic conflict. Our study employs an experimental design wherein we manipulate policy-specific information by generating ad hoc political information related to ethnic conflict. The statistical methods of analysis are logistic regression and analysis of covariance. The results demonstrate that both political information and anger have a significant impact on an individual’s cognitive processing and policy preferences regarding ethnic conflict interventions. Specifically, political information increases one’s proclivity to choose non-military policy options, whereas anger instigates support for aggressive …

On The Need For Embodied And Dis-Embodied Cognition,

On The Need For Embodied And Dis-Embodied Cognition, Guy Dove
Faculty and Staff Scholarship
This essay proposes and defends a pluralistic theory of conceptual embodiment. Our concepts are represented in at least two ways: (i) through sensorimotor simulations of our interactions with objects and events and (ii) through sensorimotor simulations of natural language processing. Linguistic representations are “dis-embodied” in the sense that they are dynamic and multimodal but, in contrast to other forms of embodied cognition, do not inherit semantic content from this embodiment. The capacity to store information in the associations and inferential relationships among linguistic representations extends our cognitive reach and provides an explanation of our ability to abstract and generalize. This …

The Plight Of “Big Black Dogs” In American Animal Shelters: Color-Based Canine Discrimination, Amanda Leonard
Attitudes Towards Animals Collection
The paper begins by describing Big Black Dog Syndrome and its effects in shelters across the United States. I then discuss the physical and environmental factors that contribute to BBD Syndrome; Western symbolism associated with the color black, historical examples of black dogs as negative entities in Western culture, and the concept of “unconscious background checking,” which negatively impacts the adoption rates of BBDs. Lastly, I offer some suggestions as to how shelters in the United States can ameliorate the negative effects of BBD Syndrome.

The Effect Of Priming A Thin Ideal On The Subsequent Perception Of Conceptually Related Body Image Words, Conor T. Mclennan
Psychology Faculty Publications
Our research examined the effects of thin ideal priming on the perception of body image words in participants without an eating disorder. Half of the participants were primed by viewing thin models, and half were primed with gender-neutral shoes. Subsequently, all participants (N=56) completed a Stroop task for three categories of words: neutral (BOOKS), shoe (CLOGS), and body (THIGHS). Lastly, all participants completed a body dissatisfaction questionnaire. We predicted that body dissatisfaction scores would be correlated with the Stroop effect. We found a significant correlation between body dissatisfaction and the body effect of slower color naming times for the body …

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 …

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 …

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 …

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 …

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 …

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
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, …

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 …

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 …

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 …

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 …

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 …
