Psychometric Properties Of Diagnostic Assessment Instrumentsfor Autism Spectrum Disorders In A Community Sample Aged 2 Through 17 Years, Sheryl Lozowski-Sullivan

Dissertations

Recent estimates of the incidence and prevalence of autism spectrum disorders (ASDs) indicate substantial increases over the past 20 years (Centers for Disease Control and Prevention, 2009; Fombonne, 2009; Matson & Kozlowski, 2011; Schreibman & Koegel, 2005; Wing & Porter, 2002), in part because of the availability of significantly improved diagnostic assessment instruments (Lord & Corsello, 2005; Schreibman, 2005). In highly structured research settings, some of these diagnostic instruments correlate well with each other; however, few studies have examined the relation between these diagnostic tools in traditional clinical practice (Mazefsky & Oswald, 2006; South et al, 2002). This study examined …

The Psychological Foundations Of Behavioral Law And Economics, Jeffrey J. Rachlinski

Cornell Law Faculty Publications

Over the past decade, psychological research has enjoyed a rapidly expanding influence on legal scholarship. This expansion has established a new field—“Behavioral Law and Economics” (BLE). BLE’s principal insight is that human behavior commonly deviates from the predictions of rational choice theory in the marketplace, the election booth, and the courtroom. Because these deviations are predictable, and often harmful, legal rules can be crafted to reduce their undesirable influence. Ironically, BLE seldom recognizes that its intellectual origins lie with psychology more so than economics. This failure leaves BLE open to criticisms that can be answered only by embracing the underlying …

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 …

Bilingual Homonym Disambiguation At The Discourse Level, Yvette Aguilar Baca

Open Access Theses & Dissertations

The objective of this study was to investigate the effects of global context and local context on the time course of activation of cognate homonyms for bilingual readers. Of interest was whether meaning frequency, context, and cross-language activation modulated the time course of activation of the subordinate meaning of cognate homonyms. Also, whether the subordinate bias effect would be altered or even eliminated by the combined influence of such contextual factors and cross-language activation. Eye movements of Spanish-English bilinguals were measured using an eye-tracking device while they read English paragraphs. The paragraphs contained cognate homonyms (e.g. novel/novela), cognate non-homonyms (e.g. …

Resilience Factors Affecting The Readjustment Of National Guard Soldiers Returning From Deployment, D. Patricia Tackett

Antioch University Dissertations & Theses

Following the September 11, 2001 attack on the United States, there has been increased utilization of the Reserve Components (RC) by the military to fight the wars in Iraq and Afghanistan. Service members in the National Guard and Reserve (NG/R) represent approximately 40% of the forces involved in these conflicts. Current research indicates that NG/R personnel and their families may be at greater risk to deployment stressors than their Active Component counterparts. Estimates for the development of mental health problems including PTSD among returning RC personnel, range as high as 42%. The focus of this study was to advance the …

A Conceptualization Of Treatment Stigma In Returning Veterans, Jason B. Flick

Antioch University Dissertations & Theses

The dissertation project combines three theoretical models that inform conceptualizations of the origins, manifestations, and consequences of stigma: the Social Psychological model (SPM), the Sociological model (SM), and the Cognitive-behavioral model (CBM). These models merge into a single, integrative lens, through which stigma can be examined on both cultural and individual levels. This lens is then applied to the cultural and individual manifestations of the stigma of seeking psychological treatment experienced by veterans who have served in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF). Through this lens, an understanding of the inception, maintenance, and effects of this treatment …

How Leaders Think: Measuring Cognitive Complexity In Leading Organizational Change, Iva Vurdelja

Antioch University Dissertations & Theses

The ability to lead complex organizational change is considered the most difficult leadership responsibility. Habitual linear thinking based on sequential procedural decision making is insufficient when responding to ambiguous and unpredictable challenges and interpreting systemic variables in the context of unforeseen problems, risks, and invisible interrelationships. The purpose of this exploratory multiple case study was to expand our understanding of the structure of the thinking employed by executive leaders as initiators and enablers of complex, large-scale organizational change. The researcher integrated knowledge of adult cognitive development and organizational leadership to examine the higher forms of reasoning abilities required for dealing …

When A Promotion Is Denied: The Effects Of Decision Stage On Perceptions Of Promotion And Price Fairness, Monika Kukar-Kinney, Lan Xia, Kent B. Monroe

Marketing Faculty Publications

Marketers frequently use promotions to enhance sales and increase consumers' perceptions of value. However, most promotions usually come with restrictions, such as time expiration, quantity or product model restriction, etc. In the present research, the effect of the stage in the purchase process when the consumer finds out about the restriction is investigated. The findings indicate that the later in the purchase process the consumer discovers the restriction, the greater is the perception that the effort invested into the purchase is wasted, consequently resulting in lower promotion and price fairness. This effect is mediated through the feeling of entitlement to …

A Randomized Trial Examining The Effects Of Parent Engagement On Early Language And Literacy: The Getting Ready Intervention, Susan M. Sheridan, Lisa Knoche, Kevin A. Kupzyk, Carolyn P. Edwards, Christine A. Marvin

Department of Educational Psychology: Faculty Publications

Language and literacy skills established during early childhood are critical for later school success. Parental engagement with children has been linked to a number of adaptive characteristics in preschoolers including language and literacy development, and family-school collaboration is an important contributor to school readiness. This study reports the results of a randomized trial of a parent engagement intervention designed to facilitate school readiness among disadvantaged preschool children, with a particular focus on language and literacy development. Participants included 217 children, 211 parents, and 29 Head Start teachers in 21 schools. Statistically significant differences in favor of the treatment group were …

Adolescents Are Young Adults, Not Immature Brains, David Moshman

Department of Educational Psychology: Faculty Publications

When G. Stanley Hall (1904) wrote the first book on adolescence at the turn of the 20th century, he was describing a new cultural phenomenon that had emerged in the United States and other industrializing societies during the late 19th century. There had always been children, whether or not we theorized about them, but there had not always been adolescents.

Of course, there have always been teenagers in the mathematical sense of persons who have reached the age of 13 years but not yet 20 years (and in the linguistic sense that these are the ‘‘teen’’ years in our counting …

Readers’ Knowledge Of Functional Devices, Hung-Tao Chen

University of Kentucky Master's Theses

Various writing devices are designed to serve specialized purposes or “functions” to aid readers in their processing of a text. For example, an index lists important topics in the book and allows the readers to quickly locate the pages relevant to a particular topic. The purpose of this study was to learn what mature readers know about various functional devices. Two experiments were conducted to learn what readers know about functional devices in texts. Experiment 1 investigated readers’ knowledge about functional writing devices and Experiment 2 examined readers’ beliefs about the relevance of functional writing devices in various reading situations. …

The Influence Of Hiv Stigma And Disclosure On Psychosocial Behavior, James Minson

Walden Dissertations and Doctoral Studies

Human Immunodeficiency Virus (HIV) remains a serious public health issue, and many social factors are involved in virus transmission and treatment. The current conceptualization of how HIV status disclosure and perceived stigma of HIV diagnosis interact is undeveloped. This study was based on social cognitive theory and tested hypothesized positive relations between HIV serostatus disclosure, social support, and self-efficacy. In addition, self-rated HIV stigma was examined as a potential mediating variable. Participants were 109 HIV positive, mostly White gay men recruited via an online bulletin board. They completed the medical outcomes study social support survey, the general self-efficacy scale, the …

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 …

A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk

Walden Dissertations and Doctoral Studies

Researchers have identified inadequate sleep duration as one of the factors contributing to global obesity. The purpose of this study was to test a hypothesis deduced from a new sleep-duration-based evolutionary theory claiming that sleep extension in response to lengthening night duration in early fall evolved into a behavioral marker of an approaching winter; this adaptive trait was theorized to produce adiposity gain in White men in response to sleep extension. The hypothesis was that White Americans would show a greater increase in the age-adjusted fat mass index per unit of sleep duration compared to that of Black Americans. Data …

Enhancing The Ability Of Adults With Mild Mental Retardation To Recognize Facial Expression Of Emotions, Juna Michel

Walden Dissertations and Doctoral Studies

A critical element in the development of interpersonal skills is the ability to recognize facial expressions. However, in persons with mild mental retardation (PMR), social interactions based on the recognition of others' emotional states may be compromised. Guided by the theory of mind, which allows one to make inferences on someone's mental states, differentiate facts from friction, and process others' beliefs and intentions, this study determined if emotion training impacted future emotion recognition scores in a PMR population and whether the variables of gender, age, and baseline Facial Expression of Emotions Stimuli and Test (FEEST) scores predicted changes in emotion …

Adult Outpatients With Major Depressive Disorder Forming Positive Responses During Challenging Events, Michelle Renee Victoria

Walden Dissertations and Doctoral Studies

Previous empirical research demonstrated that major depressive disorder (MDD) had a profound impact on adults. What remained unaddressed in the research was the ability of those with MDD to form positive responses during challenging life events. The purpose of this exploratory quantitative study was to examine the cognitive ability of MDD patients to form positive responses on a standardized psychological assessment. This study, guided by Beck's cognitive theory of depression, was designed to determine whether depressed individuals were prone to negativity and had decreased ability to form positive responses to challenging situations. A 2x2 ANOVA was used to analyze 116 …

Academic Self-Efficacy Beliefs Of Young Adults With Learning Disabilities, Karin Ann Marie Coles

Walden Dissertations and Doctoral Studies

Positive academic self-efficacy beliefs are associated with increased motivation, higher levels of persistence, and overall academic success. There is a gap in the literature regarding how young adult learners with identified learning disabilities who are also enrolled in postsecondary education characterize their development of academic self-efficacy beliefs and corresponding adaptive coping skills. The purpose of this phenomenological study was to develop a meaningful understanding of the lived experiences of young adult students with learning disabilities in the development of their self-efficacy beliefs and adaptive coping skills. Social learning theory, particularly the self-efficacy belief components, was the guiding conceptual framework for …

Neural Mechanisms Of Interference And Storage In Vibrotactile Working Memory, Tyler D. Bancroft

Theses and Dissertations (Comprehensive)

Vibrotactile working memory has attracted increasing attention in recent years. Substantial research into the neural correlates has been conducted, especially using single-cell paradigms in non-human primates (Romo & Salinas, 2003). The vibrotactile working memory system uses a relatively simple neural code for the representation of stimuli, making it possible to determine when stimulus information is present in the various cortical areas thought to be involved. In humans, vibrotactile working memory displays properties (such as overwriting mechanisms of interference) that make it an ideal system for testing general theories of working memory. In the present study, we demonstrate that vibrotactile working …

Indentifying And Understanding User Preferences In Generic Planning Tools, Grisel Ventura

Open Access Theses & Dissertations

Planning is an important cognitive work activity. To support this complex task, the development of planning tools is important to support people during decision-making and problem-solving tasks. Nowadays, a large number of manual and electronic tools support this complex activity; manual and electronic planning tools aid people in creating strategies for effective work performance. However, there is limited information on the design of generic planning tools people use for their activities, and why people choose to use the planning tool they do. Some examples of generic tools for planning are calendars, checklists, agendas, etc.

To answer this question, this research …

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 …
