The Effect Of Endpoint Knowledge On Dot Enumeration, Alex Michael Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study attempts to extend the principle tenets of the Overlapping Waves Theory (Siegler, 1996), a framework designed to explain the progression of trends in cognitive development, to adult participants’ performance in a dot enumeration task. Literature in the 0-100 number line estimation task (Siegler & Booth, 2004, Ashcraft & Moore, 2011) has revealed a pervasive trend in child estimation such that young children (especially those in kindergarten) respond with a logarithmic line of best fit, while children at the third grade and above overwhelmingly respond with linear estimates to this same range of numbers. A similar developmental trend is …

Executive Function Profiles In Pediatric Traumatic Brain Injury, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traumatic brain injury is a common cause of disability and death among children in the United States. Insult to the frontal and temporal lobes are frequent in closed head brain injury. Cognitive deficits in a variety of domains are common sequelae of brain trauma. In many cases, trauma to the frontal and temporal lobe regions engender prominent deficits in higher-order cognitive processing, memory, and attention.

Higher-order cognitive processing, or Executive Functions are the grouping of cognitive processes necessary for organization of thoughts and activities, attending to the activities, prioritizing tasks, managing time efficiently, and making decisions (Alvarez & Emory, 2006; …

Loving The World And Our Children Enough--Nurturing Decidedly Different Scientifc Minds, By Design, Stephanie Pace Marshall

Publications & Research

Wise world-shaping and problem-solving requires that we and our children think in decidedly different, integral and wise ways. This transformation requires a fundamental shift in consciousness and the emergence of global minds that can creatively live into a new worldview of an interconnected planet and a sustainable and interdependent human family. "The fullness of our humanity and the sustainability of our planet rest with the nurturing of decidedly different minds."

Speeded Retrieval Abolishes The False Memory Suppression Effect: Evidence For The Distinctiveness Heuristic, C. S. Dodson, Amanda C. Gingerich

Amanda C. Gingerich

We examined two different accounts of why studying distinctive information reduces false memories within the DRM paradigm. The impoverished relational encoding account predicts that less memorial information, such as overall famililarity, is elicited by the critical lure after distinctive encoding than after non-distinctive encoding. By contrast, the distinctiveness heuristic predicts that participants use a deliberate retrieval strategy to withhold responding to the critical lures. This retrieval strategy refers to a decision rule whereby the absence of memory for expected distinctive information is taken as evidence for an event’s nonoccurrence. We show that the typical false recognition suppression effect only occurs …

Why Distinctive Information Reduces False Memories: Evidence For Both Impoverished Relational-Encoding And Distinctiveness Heuristic Accounts, Amanda C. Gingerich, C. S. Dodson

Amanda C. Gingerich

Two accounts explain why studying pictures reduces false memories within the Deese-Roediger-McDermott paradigm (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995). The impoverished relational-encoding account suggests that studying pictures interferes with the encoding of relational information, which is the primary basis for false memories in this paradigm. Alternatively, the distinctiveness heuristic assumes that critical lures are actively withheld by the use of a retrieval strategy. When participants were given inclusion recall instructions to report studied items as well as related items, they still reported critical lures less often after picture encoding than they did after word encoding. …

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. …

Effects Of Bilingualism On Goal Representation And Maintenance, Amina Saadaoui

Theses Digitization Project

The main focus of this study was to examine whether the bilingual advantage in cognitive control is due to the bilinguals' ability to represent and maintain goal information in working memory. Cognitive control, also referred to as executive control, is the ability to inhibit one cognitive task while executing another task.

Reflexivity In Financial Markets: A Neuroeconomic Examination Of Uncertainty And Cognition In Financial Markets, Steven Pikelny

Senior Projects Spring 2011

Financial markets exist to disperse the risks of an unknown future in an economy. But for this process to work in an optimal fashion, investors – and subsequently markets – must have a way to interpret uncertainty. The investor rationality and market efficiency literature utilizes a methodology inadequate to address this fact, so I supplement it with the perspectives of epistemology, economic sociology, neuroscience, cognitive science, and philosophy of mind. This approach suggests that what is commonly viewed as market “inefficiency” is not necessarily caused by investor irrationality, but rather by the inherent nature of the epistemological problem faced by …

Improving Awareness Of Vulnerabilities To Ethical Challenges: A Family Systems Approach, Cecile Brennan, Jennifer Eulberg, Paula Britton

Cecile Brennan

Current ethical decision-making models focus principally on cognitive factors and less on the emotional aspects of ethical challenges. This practice reflects a reliance on knowledge-driven, modernist approaches that emphasize objectivity and the primacy of rational thinking. Newer postmodern and constructivist approaches emphasize the need to consider the counselor holistically, as a thinking/feeling being who brings into the present moment the accumulated weight of the past. In order to bridge the gap between a cognitive, modernist approach and a feeling, experience-based postmodern approach, the authors outline an instructional approach that uses family systems theory to assist counselors in becoming conscious about …
