A Comparison Of Bias In Four Measures Of Monitoring Accuracy, Fred Kuch

UNLV Theses, Dissertations, Professional Papers, and Capstones

Typically in calibration research, subjects perform a task and make a judgment about the success of the task. Accurate findings help subjects improve self-calibration. In addition, researchers rely on the accuracy of findings to make inferences about underlying metacognitive processes. Consequently, it is important that the measures used to assess monitoring accuracy are as free of bias as possible. Bias indicates whether an observed value of monitoring accuracy over- or underestimates the true value.

This study examined gamma and three other viable statistics, d', C, and the G Index, currently used to measure monitoring accuracy. Using Monte Carlo simulation techniques, …

Modality-Specific And Modality-General Encoding Of Auditory And Visual Rhythms, Amanda Pasinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The perception of timing information plays a large role in our everyday activities, yet we still do not accurately understand the mechanisms underlying these perceptions. Both modality-general and modality specific mechanisms have been suggested to account for perceptual timing. The use of a new auditory tempo perception paradigm can be used to examine various brain responses - measured via electroencephalography (EEG) - thought to index timing perception. This study applied this paradigm to both auditory and visual rhythms, and compared event-related potentials (ERPs) to task performance. Auditory and visual contingent negative variation (CNV) components showed two distinct voltage patterns across …

Facial Expression Processing Is Holistic Or Feature-Based Depending On Stimulus Format: Evidence From The Composite Face Illusion And Gaze-Contingent Stimulus Presentations, Emily R. Prazak

Psychology Honors Projects

Controversy exists over whether facial expression recognition is a holistic or feature-based process. The present research explored whether stimulus format (photographic vs. schematic) affects the type of processing used. In a composite/noncomposite expression recognition task, holistic processing was observed for photographic stimuli and feature-based processing was observed for schematic stimuli. Moreover, holistic processing in the photographic condition increased when more than one individual was presented. Results suggest that facial expression processing is holistic under natural viewing conditions and provide a potential resolution to the previous controversy. Such findings may be corroborated by an ongoing follow-up study using gaze-contingent stimulus presentations.

Public Support For Military Interventions Across Levels Of Political Information And Stages Of Intervention: The Case Of The Iraq War, Cigdem Sirin

Selected Works Temporary Series

This study examines the effect of political information levels and intervention stages on the formation and continuity of public support for military interventions by analyzing survey data pertaining to the 2003 military intervention in Iraq. The results show that before and immediately after the launch of the intervention, politically uninformed individuals expressed higher support for the war compared to politically informed ones. However, as the intervention proceeded and casualties were incurred, higher rates of decrease in support were observed among the politically uninformed. Politically informed individuals, on the other hand, demonstrated more stable levels of support throughout the course of …

The Cognitive Representation Of Fantasy Versus Pretense, Colleen Mcinnis

Psychology Student Scholarship

Do our minds process fantasy, pretense, and reality differently? Participants read fantastical (Snow White eating an apple), pretend (a girl pretending to be Snow White), or realistic (a girl eating an apple) vignettes. Participants’ reaction to a property of each vignette’s realistic context (apple as ‘delicious’) or its unrealistic context (apple as ‘poisonous’) was measured by a computer program. Differences in study 1 reaction time indicate that fantasy may require different mental representation than pretense and reality. Differences in study 2 fail to duplicate results from the fantasy condition in study 1, instead finding differences in mental representation after reading …

An Erp Study Of Responses To Emotional Facial Expressions: Morphing Effects On Early-Latency Valence Processing, Zoe Ravich

Scripps Senior Theses

Early-latency theories of emotional processing state that at least coarse monitoring of the emotional valence (a pleasure-displeasure continuum) of facial expressions should be both rapid and highly automated (LeDoux, 1995; Russell, 1980). Research has largely substantiated early-latency differential processing of emotional versus non-emotional facial expressions; however, the effect of valence on early-latency processing of emotional facial expression remains unclear. In an effort to delineate the effects of valence on early-latency emotional facial expression processing, the current investigation compared ERP responses to positive (happy and surprise), neutral, and negative (afraid and sad) basic facial expression photographs as well as to positive …

Useful Field Of View Predicts Driving In The Presence Of Distracters, Joanne M. Wood, Alex Chaparro, Philippe Lacherez, Louise Hickson

Publications

Purpose. The Useful Field of View (UFOV®) test has been shown to be highly effective in predicting crash risk among older adults. An important question which we examined in this study is whether this association is due to the ability of the UFOV to predict difficulties in attention-demanding driving situations that involve either visual or auditory distracters.

Methods. Participants included 92 community-living adults (mean age 73.6 +- 5.4 years; range 65– 88 years) who completed all three subtests of the UFOV involving assessment of visual processing speed (subtest 1), divided attention (subtest 2), and selective attention (subtest 3); driving safety …

Creation Of False Memories And Beliefs: Expectancy Consistent Errors Based On Gender Stereotypes, Arianna Stelling

Undergraduate Theses and Capstone Projects

This study was a series of three experiments which examined the effects of gender stereotypes on the creation of false-memories. Participants were undergraduate students who viewed a short one-scene video depicting a couple on a date. The video featured a man and a woman displaying a mixture of typical, atypical, or a combination of both gender stereotypical behaviors. Following the video, participants completed a quiz to determine whether they created false memories consistent with gender stereotypes. Participants completed an attitudinal scale to gauge their views on gender stereotypes. It was hypothesized that participants would create stereotype- consistent false memories and …

Agenda Setting From The Oval Office: An Experimental Examination Of Presidential Influence Over The Public Agenda, José Villalobos, Cigdem Sirin

Selected Works Temporary Series

This study employs an experimental approach to isolate and directly test the extent to which presidents can affect public perceptions of issue importance and support for policy action, taking into consideration key factors that condition such effects. Our findings provide new empirical evidence that presidents can, in fact, positively influence public opinion through agenda setting, particularly by increasing the perceptual importance of low salience foreign policy issues. However, the results also indicate that such positive effects do not translate into public support for policy action; instead, presidential appeals actually decrease support. Last, our study offers new evidence that employing bipartisan …

The research methods used were historical research and content analysis. Through thorough examination …

Melatonin And Its Effect On Learning And Memory, Nechama Leah Bauman (Cahn)

The Science Journal of the Lander College of Arts and Sciences

Melatonin is a neurohormone produced by the pineal gland and secreted into the body in a circadian rhythm. Melatonin is known to be involved in many vital body functions, including sleep, reproduction, and immune response. Exogenous melatonin, sold as over the counter natural supplements in drugstores, is commonly taken by many people to help cure various ailments. Melatonin also plays a role in the hippocampus. This paper investigates the effects of melatonin on long-term potentiation in the hippocampus. Long-term potentiation, described as a long-lasting strengthening of synapses between nerve cells, is thought to be responsible for long-term memory retention. It …

CGU Faculty Publications and Research

Mindfulness refers to an enhanced attention to and awareness of present moment experience. This study examined how trait mindfulness, as measured with six items from Mindfulness Attention Awareness Scale, might influence adolescent cigarette smoking frequency through its impact on depressive affect, anger affect and perceived stress mediators. Self-reported data from Chinese adolescents (N = 5287, mean age = 16.2 years, SD = 0.7; 48.8% females) were collected within 24 schools. The product of coefficients test was used to determine significant mediation paths. Results from baseline cross-sectional data indicated that trait mindfulness had a significant indirect effect on past 30-day …

Examining The Role Of Identity In Negotiation Decision Making: The Case Of Cyprus, Cigdem Sirin

Selected Works Temporary Series

This study examines the effects of ethnic and social identities on negotiation decision making in the context of the Cyprus conflict. I conduct a theory-driven case study of the 1959 Zurich-London agreements on Cyprus, analyzing the positions of Turkey, Greece, Britain, and the Turkish and Greek Cypriot communities during the negotiation process. I find that even in the presence of adversarial ethnic ties, decision makers who have a shared (and salient) social identity are more likely to employ collective-serving decision strategies and seek evenhanded solutions that will not jeopardize their mutual interests. In contrast, decision makers with severe ethnic fragmentation …

Examinng Talker Effects In The Perception Of Native And Foreign-Accented Speech, Conor T. Mclennan, Julio Alvarez Gonzalez

Psychology Faculty Publications

Understanding the circumstances under which talker (and other types of) variability affects language perception represents an important area of research in the field of spoken word recognition. Previous work has demonstrated that talker effects are more likely when processing is relatively slow (M(c)Lennan & Luce, 2005). Given that listeners may take longer to process foreign-accented speech than native-accented speech (Munro & Derwing, Language and Speech, 38, 289-306 1995), talker effects should be more likely when listeners are presented with words spoken in a foreign accent than when they are presented with those same words spoken …
