Choice-Dependent Perceptual Biases, Long Luu, Alan A. Stocker
MODVIS Workshop
The perceived motion direction of a dynamic random dot stimulus is systematically biased when preceded by a motion discrimination task (Jazayeri and Movshon, 2007). The biases were originally thought to occur because subjects mistakenly reuse the neural read-out optimized for the discrimination task when forming the percept (Fig.1a, Task-dependent model). In a series of experiments, we demonstrated that this explanation is incorrect and that the biases actually result from the conditioning of the percept on the preceding discrimination judgment (Fig1.b, Choice-dependent model). Experiment 1 was aimed at replicating the biases for an orientation stimulus. Subjects first indicated whether the stimulus …

Focusing On Selection For Fixation, John K. Tsotsos, Calden Wloka, Yulia Kotseruba
MODVIS Workshop
Building on our presentation at MODVIS 2015, we continue in our quest to discover a functional, computational, explanation of the relationship among visual attention, interpretation of visual stimuli, and eye movements, and how these produce visual behavior. Here, we focus on one component, how selection is accomplished for the next fixation. The popularity of saliency map models drives the inference that this is solved; we suggested otherwise at MODVIS 2015. Here, we provide additional empirical and theoretical arguments. We then develop arguments that a cluster of complementary, conspicuity representations drive selection, modulated by task goals and history, leading to a …

Learning Object Representations For Modeling Attention In Real World Scenes, Alex Schwarz, Frederik Beuth, Fred H. Hamker
MODVIS Workshop
Models of visual attention have been rarely used in real world tasks as they have been typically developed for psychophysical setups using simple stimuli. Thus, the question remains how objects must be represented to allow such models an operation in real world scenarios. We have previously presented an attention model capable of operating on real-world scenes (Beuth, F., and Hamker, F. H. 2015, NCNC, which is a successor of Hamker, F. H., 2005, Cerebral Cortex), and show here how its object representations have been learned. We have used a learning rule based on temporal continuity (Földiák, P., 1991, Neural Computation) …

Correlates Of Appearance And Weight Satisfaction In A U.S. National Sample: Personality, Attachment Style, Television Viewing, Self-Esteem, And Life Satisfaction, David Frederick, Gaganjyot Sandhu, Patrick J. Morse, Viren Swami
Psychology Faculty Articles and Research
We examined the prevalence and correlates of satisfaction with appearance and weight. Participants (N = 12,176) completed an online survey posted on the NBCNews.com and Today.com websites. Few men and women were very to extremely dissatisfied with their physical appearances (6%; 9%), but feeling very to extremely dissatisfied with weight was more common (15%; 20%). Only about one-fourth of men and women felt very to extremely satisfied with their appearances (28%; 26%) and weights (24%; 20%). Men and women with higher body masses reported higher appearance and weight dissatisfaction. Dissatisfied people had higher Neuroticism, more preoccupied and fearful attachment …

Educating Spouses May Be Key To Helping Veterans, Shawn J. Gourley
Montview Journal of Research & Scholarship
Veterans’ and family members are facing great difficulties when the veteran returns home to transition into civilian life. Marriages are struggling, and families are being torn apart when the veteran returns home with Post Traumatic Stress Disorder (PTSD). Although there are many programs that have been created to educate spouses about PTSD, however, they often fall short of being able to prepare a family for the actual experience of transition. The Department of Veterans Affairs (VA) is starting to come up with programs to help couples and research is starting to gain empirical support; there are still many couples left …

Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler
Senior Honors Projects, 2010-2019
Recent psychoacoustic experiments (Böckmann-Barthel et al., 2014; Deike et al., 2012) have re-examined research regarding stream segregation and the build-up effect. Stream segregation is the ability to discern auditory objects within a stream of information, such as distinguishing one voice amongst background noise or an instrument within an orchestra. Initial works examining this topic proposed that auditory information is not immediately distinguished as various streams, but rather that differences accumulate over time, allowing listeners to segregate information following a period of build-up (i.e., the build-up effect); whereas more current findings indicate a build-up period is unnecessary for segregation. This experiment’s …

The Achievement Gap And Students Living In Poverty: The Role Of Core Self-Evaluation And Transformational Leadership In Teachers, India Harris
Dissertations, 2014-2019
Research has shown that the combination of locus of control, self-efficacy, self-confidence, and emotional stability is a good predictor of life success. Until now, this second order factor, called core self-evaluations (CSE) has only been studied in adults. Findings from this study, showed levels of CSE were significantly and positively connected with academic achievement for middle and elementary aged students. CSE appears to play to a similar role between students and academic achievement as it plays with adults and job performance. In this study, the dimensions of transformational leadership were applied to teacher behaviors and students were grouped based on …

Context Effects Of False Remember Responses In Older And Younger Adults, Casey M. Williamson
Masters Theses, 2010-2019
Although different theories attempt to explain the underlying mechanism of false remembers, none have been able to adequately describe this process. The current study aims to determine if a specific contextual detail (i.e., font color) can be tied to false remembers (i.e., false memory that contains contextual or perceptual details), and if there are age differences in this ability. Using the Deese, Roediger, McDermott (DRM) paradigm (Deese, 1959; Roediger & McDermott, 1995) and the contextual detail of font color, this study investigated if older and younger adults can tie a specific color to studied items and critical lures (non-presented semantic …

The Effect Of Descriptive Norms On Resistance Exercise Self-Efficacy In College-Aged Females 2016, Justin Kompf
Master's Theses
Resistance training is a form of physical activity that provides substantial health benefits. Despite these widespread benefits, participation in resistance training is considerably low, particularly among females. To engage in a skill-related activity such as resistance training, individuals need to have confidence in their abilities. Self-efficacy is a cognitive construct that is used to describe situation-specific self-confidence. Descriptive norms are a type of social norm that describes the behavior of others. Descriptive norms have been useful in positively changing health related behaviors. The exact mechanism of how descriptive norms alter behavior is unknown. However, it has been show in research …

Chapman University
The Development Of The Scale Of Contemplative Practice In Higher Education, Maryann Krikorian
Educational Studies Dissertations
Some scholars have formed a more expansive view of knowledge that moves beyond the cognitive notion of intellect. For example, emotional intelligence (EI) theory posits that human intelligence encompasses both cognitive and emotional competencies, providing a framework for the concept of contemplative practices in an endeavor to support an eclectic understanding of cognition. Contemplative practices may benefit graduate student disposition and inform areas of educator preparation through the use of emotional adeptness in higher education. The purpose of this study was to: (a) develop a self-report measure: Scale of Contemplative Practice in Higher Education (SCOPE); (b) address the issues of …

All Faculty Scholarship for the College of the Sciences
Regret is one of the most common emotions, but researchers generally measure it in an ad-hoc, unvalidated fashion. Three studies outline the construction and validation of the Regret Elements Scale (RES), which distinguishes between an affective component of regret, associated with maladaptive affective outcomes, and a cognitive component of regret, associated with functional preparatory outcomes. The present research demonstrates the RES’s relationship with distress (Study 1), appraisals of emotions (Study 2), and existing measures of regret (Study 3). We further demonstrate the RES’s ability to differentiate regret from other negative emotions (Study 2) and related traits (Study 3). The scale …

Eyes Wide Open: Pupil Size As A Proxy For Inhibition In The Masked-Priming Paradigm, Jason Geller, Mary L. Still, Alison L. Morris
Psychology Faculty Publications
A core assumption underlying competitive-network models of word recognition is that in order for a word to be recognized, the representations of competing orthographically similar words must be inhibited. This inhibitory mechanism is revealed in the masked-priming lexical-decision task (LDT) when responses to orthographically similar word prime-target pairs are slower than orthographically different word prime-target pairs (i.e., inhibitory priming). In English, however, behavioral evidence for inhibitory priming has been mixed. In the present study, we utilized a physiological correlate of cognitive effort never before used in the masked-priming LDT, pupil size, to replicate and extend behavioral demonstrations of inhibitory …

Teachers' Perceptions Of Students' Creativity Characteristics, Serap Gurak-Ozdemir
Creative Studies Graduate Student Master's Theses
Teachers’ perceptions of an ideal student were investigated in terms of their FourSight preferences (i.e. Ideator, Clarifier, Developer, and Implementer). Based on these preferences, 275 teachers who were currently working in Western New York region described their “ideal” student with 66 adjectives of Torrance Ideal Child Checklist. Results showed that for each of FourSight preferences, teachers have a tendency to support characteristics associated with their own preference. More specifically, teachers with a stronger Ideator tendency encouraged the students’ Ideator characteristics more compared to Developer and Implementer styles. Teachers with a Clarifier tendency do not seem to favor students’ Ideator characteristics …

Building Object Representations: Mechanisms Of Perceptual Learning In Human Visual Cortex, Stephanie M. Long
Psychological Science Undergraduate Honors Theses
Extensive literature in the cognitive neurosciences has been dedicated to understanding the neural processes involved in object category learning. However, much remains to be learned regarding the mechanisms by which high-level visual patterns are extracted from a crowded visual scene, segregated into discrete object categories, and represented in the cortical visual hierarchy. Here, we used event-related potentials (ERPs) to investigate the neural underpinnings of visual object category extraction in a cluttered visual environment. Electroencephalography (EEG) was continuously recorded while subjects were given a hybrid of an object category learning and visual search task. In this hybrid task, a peripheral array …

The Threat Of Innovation: Tactics To Improve Small Team Creative Outcomes In Risk-Averse Organizations, Paul Gaylo
Creativity and Change Leadership Graduate Student Master's Projects
This project explores the paradox that creativity is generally viewed as a positive force and is a desired trait or characteristic, yet when faced with the true cost of creativity, individuals and organizations may purposefully or inadvertently suppress creativity. Real world examples are used to frame the applicability of this project to the typical large and complex technical product organization. The project includes a review of creativity scholarship in the context of organizations and a discussion to establish the foundational science behind this paradox. The project introduces the new creativity readiness level index, and a survey strategy to gauge organizational …

How Musical Oddballs Warp Psychological Time, Rhimmon Simchy-Gross
Graduate Theses and Dissertations
Oddballs—low-probability, attention-capturing expectancy violations—are judged as longer than non-oddballs, but are temporal intervals that contain oddballs judged as longer than those that do not? In 2 experiments, we tested competing model predictions using a novel and covert measure of subjective duration—musical imagery reproduction. Participants verbally estimated and reproduced with musical imagery repeated, coherent, or incoherent familiar or unfamiliar chord sequences (3.5 s, 7 s, or 12 s) that either did or did not contain dynamic auditory oddballs. Participants verbally estimated repeated chord sequences that contained oddballs as shorter than those that did not, but reproduced with musical imagery incoherent chord …

Environmental enrichment is an important component in maintaining the welfare of animals housed in human care. While a variety of enrichment types (e.g., objects, food, sound) have been utilized, a major challenge in developing enrichment is determining the enrichment potential of various techniques for individual animals. In this study, the efficacy of video clips as enrichment devices was assessed in two species of captive dolphins, exposed to video footage accompanied by sound. Videos were evenly divided into five categories, based on content, and played at underwater viewing windows across 20 sessions while the animals were housed with conspecifics. Species and …

Although prior research suggests that playing video games can improve cognitive abilities, recent empirical studies cast doubt on such findings (Unsworth et al., 2015). To reconcile these inconsistent findings, we focused on the link between video games and task switching. Furthermore, we conceptualized video-game expertise as the onset age of active video-game play rather than the frequency of recent gameplay, as it captures both how long a person has played video games and whether the individual began playing during periods of high cognitive plasticity. We found that the age of active onset better predicted switch and mixing costs than did …
