Does Subjective Time Cost Explain Cognitive Task Choices?, Raina Ashley Isaacs
Does Subjective Time Cost Explain Cognitive Task Choices?, Raina Ashley Isaacs
Theses and Dissertations
The current literature suggests that subjective time duration could be the common currency used for task choice. However, few studies have been conducted that use non-physical tasks for their task choice options. Thus, the purpose of the current study was to examine if subjective time duration is the common currency for task choice regardless of task type. Participants first provided their subjective time estimates for each of the perceptual-motor and cognitive tasks that have been a priori determined to be at the medium difficulty level. Two cognitive tasks (item generation and math problem task) and one perceptual-motor task with a …
Effects Of Mood On Processing In Event-Based Prospective Memory, Rachel A. Workman
Effects Of Mood On Processing In Event-Based Prospective Memory, Rachel A. Workman
Theses and Dissertations
Different moods seem to elicit different processing styles (Hunt & McDaniel, 1993, Storbeck & Clore, 2005) and mood has been shown to affect retrospective memory in many ways. The current research investigated how induced mood affects event-based prospective memory (PM). The current study examined mood effects on focal and non-focal PM retrieval. Participants were induced into either a depressive or elated state using Velten statements directly prior to retrieval of the PM task. A main effect of task type was found, such that those in the focal condition completed the task quicker and more accurately than those in the non-focal …
Examining Different Reasons Why People Accept Or Reject Scientific Claims, Emilio J. C. Lobato
Examining Different Reasons Why People Accept Or Reject Scientific Claims, Emilio J. C. Lobato
Theses and Dissertations
The current project was designed to examine how cognitive style, cultural worldview, and conspiracy ideation correspond to various levels of agreement with scientific claims. Additionally, the kinds of justifications people provide for their position on scientific issues and the kinds of possible refutations of their scientific beliefs people are able to generate were qualitatively coded and analyzed. Participants were presented with a short survey asking about their level of agreement with scientific claims about biological evolution, anthropogenic climate change, pediatric vaccines, and genetically modified foods. Participants were asked two open-ended questions about each topic, one prompting participants to justify their …
Cognitive Bias And Adolescent Risk-Taking, Mayuko Nakamura
Cognitive Bias And Adolescent Risk-Taking, Mayuko Nakamura
Theses and Dissertations
Although the framing effect (i.e., the tendency of people to react differently to a particular choice depending on whether the choice is presented as a loss or as a gain) is a well-established cognitive bias among the adult population, there have been a limited number of studies with adolescent samples. In the current study, adolescents (14-18) and adults (18-26) will be asked to make choices in several decision problems including the classic Asian Disease Problem (Tversky & Kahneman, 1981) and modified “adolescent-relevant” versions that are applicable to the real-world experiences of adolescents. Individual difference measures, such as Individuals’ thinking-style (i.e., …
Examining The Role Of Executive Functions In Focal Processing Of Event-Based Prospective Memory, Tatsuya T. Shigeta
Examining The Role Of Executive Functions In Focal Processing Of Event-Based Prospective Memory, Tatsuya T. Shigeta
Theses and Dissertations
Prospective Memory (PM) refers to remembering an intention to be acted upon in the future. Such a memory may be triggered by an event (i.e., Event-based PM) where a specific cue reminds one of the previously encoded intention. PM can be assessed in a lab-setting by having subjects learn a baseline task, subsequently receiving a PM instruction, completing a distractor task, and then going through a test phase where the PM task (i.e., responding to PM cues) is embedded within the ongoing task. The multiprocess view (McDaniel & Einstein, 2000) posits that PM can be retrieved primarily using two different …
Ensemble Coding Of Semantic Information: Are Numerical Averages Generated In Parallel?, Kassandra R. Lee
Ensemble Coding Of Semantic Information: Are Numerical Averages Generated In Parallel?, Kassandra R. Lee
Theses and Dissertations
Previous research has shown evidence for the activation of ensemble coding mechanisms at multiple levels of processing complexity (Ariely, 2001; Haberman & Whitney, 2009). Here we investigated the use of ensemble mechanisms for semantic information, as well as the role of serial and parallel processing and automaticity in generating semantic ensemble representations. Twenty-seven undergraduate students completed tasks in which they reported the average value of an entire digit display or only a subset of digits, or searched for individual digits within the display. Results show that participants could average sets of numbers following only a short presentation, and that reaction …
Attention Deficits And Perception Of Emotion In Groups, Agnes Renee Strojewska
Attention Deficits And Perception Of Emotion In Groups, Agnes Renee Strojewska
Theses and Dissertations
The present study investigated the relationship between attention deficits and the recognition of emotions of either individuals or groups (ensembles). Previous research has suggested that individuals with ADHD may have deficits in social cognition, specifically in recognizing the internal (emotional) states of others, though it remains unclear whether these deficits are a discrete component of ADHD or merely the byproduct of the inattention characteristic of the disorder. Perception of ensemble characteristics, or ensemble coding, has recently been the target of increased interest in perception research, and appears to represent a powerful mechanism for processing sensory information, particularly in situations when …
Examining Possible Perceptual Proxies Of Flow State, Devin Michael Gill
Examining Possible Perceptual Proxies Of Flow State, Devin Michael Gill
Theses and Dissertations
Nakamura and Csikszentmihalyi (2002) define flow as an individual's deep engagement in an intrinsically rewarding activity. McGonigal (2011) suggests that video games are flow elicitors. If video games are flow elicitors, then spatial, agentic, and temporal perception required for game play may relate to flow in predictable manners. Over two experiments, a simple video game with contextual (i.e., implied friction) and conceptual (i.e., ambiguous stimulus labeled either bullet-train or house) manipulations was used to elicit flow. Effects of the manipulations were assessed trial-by-trial on two dimensions of flow (i.e., agency and temporal perception) and spatial planning, as well as an …
Developing & Describing The Use & Learning Of Conceptual Models For Integer Addition And Subtraction Of Grade 5 Students, Nicole Marie Wessman-Enzinger
Developing & Describing The Use & Learning Of Conceptual Models For Integer Addition And Subtraction Of Grade 5 Students, Nicole Marie Wessman-Enzinger
Theses and Dissertations
This dissertation reports the results of a teaching experiment, which explored student thinking about integer addition and subtraction. Through the lens of commognitive theory (Sfard, 2008), interpreting negative integers as secondary intuitions (Fischbein, 1987), and employing teaching experiment methodology (Steffe & Thompson, 2000), this study was a first step in developing more robust descriptions of students' conceptual models for integer addition and subtraction. I investigated: (a) the conceptual models that students exhibited, (b) the various ways that students utilized conceptual models while learning about the addition and subtraction of integers, and (c), the ways that students' conceptions evolved over the …
Task-Switching In Bilinguals: Further Investigation Of The Bilingual Advantage, Jennifer M. Brown
Task-Switching In Bilinguals: Further Investigation Of The Bilingual Advantage, Jennifer M. Brown
Theses and Dissertations
Recent research has suggested that speaking more than one language may lead to benefits across a variety of different cognitive tasks (Bialystok, Craik, Green, & Gollan, 2009). This effect has been dubbed the Bilingual Advantage. It has been suggested that this advantage relates to more the development of greater efficiency with processes involved in task-switching. The current study used a task-switching task to investigate three of these processes: reconfiguration, monitoring, and inhibitory control processes.
Monolingual and bilingual participants were presented blocks of trials in which they had to either categorize words as either abstract or concrete, or pictures as human-made …
Influence Of Seductive Details, Belief-Congruence, And Repeated Testing On Memory For Controversial Information, Daniel Adam Nuccio
Influence Of Seductive Details, Belief-Congruence, And Repeated Testing On Memory For Controversial Information, Daniel Adam Nuccio
Theses and Dissertations
People often encounter conflicting information on a wide array of topics. How they evaluate this information in relation to their current beliefs, and the effects of other influences, such as the weight given to superficial aspects of the information (e.g. pictures, anecdotes, or jargon that are at most minimally related to an author's argument), has been of interest to researchers for many years. One component of their processing
and evaluation of this information is their memory for the information. This study set out to examine the following questions: (1) Is belief-congruent in
formation remembered better or worse than belief incongruent …
Investigating Children's Intuitive And Analytical Thinking About Path Length As A Developmental Phenomenon, Cheryl Lynn Eames
Investigating Children's Intuitive And Analytical Thinking About Path Length As A Developmental Phenomenon, Cheryl Lynn Eames
Theses and Dissertations
Children's conceptions of length measurement has been the focus of research that has built on the work of Piaget and his colleagues to produce developmental accounts for the acquisition of conceptual and procedural knowledge. Prior research focused on children's developing conceptions of length measurement for straight or rectilinear paths; however, little is known about how these conceptions grow beyond the elementary grades. The present study increased the scope of this research beyond elementary grades to include middle and secondary level students, exploring the development of students' intuitive and analytical thinking for determining the length of a curved path across a …
