An Evaluation Of Traffic Control Devices And Driver Distraction On Driver Behavior At Railway-Highway Grade Crossings, Radhameris A. Gomez Gabriel

Doctoral Dissertations

At-grade crossings (grade crossings) are those crossings in which any part of a roadway intersects with railroad tracks. Safety at these railroad-highway grade crossings is a major concern, with traffic control warning devices serving as the main mechanisms for improving safety. There are three factors that influence a driver’s behavior at a given crossing. First, traffic control devices, including warning devices at the railroad-highway grade crossings, provide the driver with information whose impact will depend in part on the likelihood that the driver knows whether to glance in the direction of the device based on prior experience, and in part …

Toward A Psychological Understanding Of The Effects Of Changes In Group Status On Intergroup Relations, Katya Alex Migacheva

Doctoral Dissertations 1896 - February 2014

Societies undergoing drastic transformation are often inundated with intergroup strife, particularly, when the transformation is accompanied by drastic shifts in groups' status (e.g., Bettlehem & Janowitz, 1964). The present dissertation project aimed to begin understanding the effects of such changes in group status on intergroup outcomes, and to identify psychological processes that may underlie these effects. To achieve these goals, two studies examined perceived dimensions of status change ( magnitude, direction, and speed ) in relation to outgroup-specific outcomes (unity and threat ) and general diversity-related outcomes (attitudes toward equity, openness to diversity, and ethnocentrism ). Study 1 …

Contemplative Education: How Contemplative Practices Can Support And Improve Education, Judith Johannes

Master's Capstone Projects

The purpose of this study is to explore how contemplative education can have a viable role in education. In the first part of this thesis I will share my own personal experience with contemplative practices and how they led to my personal growth and transformation.

The second part will give some brief insights about the benefits the ancient wisdom traditions Hinduism and Buddhism attributed to contemplative practices. They claim that those practices help to reach a state of expanded awareness and stillness of the mind. Contemplative practices such as mindfulness, which is a Buddhist meditation technique, were used to better …

Word Recognition In The Parafovea: An Eye Movement Investigation Of Chinese Reading, Jinmian Yang

Doctoral Dissertations 1896 - February 2014

Chinese is a logographic writing system that drastically differs from alphabetic scripts in many important aspects. Thus, the nature of parafoveal processing in reading Chinese may be different from that in reading alphabetic languages. Here, four eye-tracking experiments using the boundary display change paradigm (Rayner, 1975) were conducted to explore the role of high level information, like semantic and plausibility information, in the parafovea for Chinese readers.

Experiments 1 and 2 used two-character words that can have the order of their component characters reversed, and still be lexical units as target words. Readers received a parafoveal preview of a target …

Modeling Source Memory Decision Bounds, Angela M. Pazzaglia

Masters Theses 1911 - February 2014

Current Signal Detection Theory models of source memory necessitate assumptions about the underlying distributions of source strengths to describe source memory performance. The current experiments applied a modified version of the same-different task in order to plot individual memory stimuli along a controlled dimension of the average frequency of voices. This technique allowed us to determine that subjects were using an independent-observations strategy rather than a differencing strategy when deciding whether two test words were spoken by the same or different female speakers at study. By including two male and two female voices and changing the task distinction from same …

Transposed Letter Effects In Prefixed Words: Implications For Morphological Decomposition, Kathleen M. Masserang

Masters Theses 1911 - February 2014

The nature of morphological decomposition in visual word recognition remains unclear regarding morphemically complex words such as prefixed words. To investigate the decomposition process, the current study examined the extent to which effects involving transposed letters are modulated when the transposed letters cross a morpheme boundary. Previous studies using masked priming have demonstrated that transposed letter effects (i.e. superior priming when the prime contains transposed letters than when it contains replacement letters) disappear or markedly decrease when the transposition occurs across a morpheme boundary. The current experiments further investigated transposed letter effects in prefixed words using both parafoveal previews in …

Do Actions Speak Louder Than Knowledge? Action Manipulation, Parent-Child Discourse And Children’S Mental State Understanding In Pretense, Dawn K Melzer

Doctoral Dissertations 1896 - February 2014

In the current study children 3-5 years of age (N = 75) participated in a mental state task to investigate the effect of action saliency on young children's appreciation of mental states during pretend play activities. They also engaged in a parent-child interaction period, including storybook reading and pretend play activities, in order to examine the relation between mental state term utterances and performance on the mental state task. Two actors appeared side-by-side on a television screen, either in motion or as static images; one actor had knowledge of the animal he was pretending to be; the other actor did …

Understanding Occlusion Inhibition: A Study Of The Visual Processing Of Superimposed Figures, Destinee L Chambers

Doctoral Dissertations 1896 - February 2014

This study investigates a phenomenon that I have termed occlusion inhibition. This research and a small number of earlier studies suggest that, in some experimental conditions, when an attended (target) object is partially occluded by a distractor object, there is less attention allocated to the occluded region of the target object than to the visible parts of that object. In the literature, there are mixed results concerning this attentional effect. Some studies find it and others do not. This study investigates the differences between those conflicting studies with the goal of identifying the factor or factors that govern when occlusion …

The Interactions Between Early Child Characteristics, Parenting, And Family Stress In Predicting Later Odd, Lindsay A. Metcalfe

Masters Theses 1911 - February 2014

The present study examined the interactions between early child behavior, early parenting, and early family stress (parent psychopathology, socioeconomic status, and stressful life events) in predicting later Oppositional Defiant Disorder (ODD) symptoms. Participants were 223 three-year-old children and their parents who participated in a four-year longitudinal study. It was predicted that there would be a stronger relationship between children’s early behavior characteristics and later ODD in the presence of less parental overreactivity/negative affect, more paternal warmth, and less family stress and a stronger relationship between early family stress and later ODD in the presence of less parental overreactivity/negative affect and …

Parenting Style Discrepancies: A Comparison Of Inter-Ethnic And Intra-Ethnic Couples, Dhara Thakar

Masters Theses 1911 - February 2014

Parenting and family interactions are thought to play a critical role in children’s development and are often key targets in clinical interventions for children with behavioral problems. Multiple factors are thought to determine patterns of parenting behavior including child and parent characteristics as well as broader social and cultural factors (Abidin, 1992; Belsky, 1984; Maccoby, 1992). Because culture is thought to influence parenting, it is possible that inter-ethnic couples may experience a greater discrepancy than intra-ethnic couples in their parenting styles, but research considering the role of different cultural backgrounds and parenting has been sparse. The current study examined whether …
