Retroactive Interference In Recognition Memory: The Effects Of Mental Effort And Similarity On Recollection And Familiarity, Caleb Jordan Picker Aug 2015

Retroactive Interference In Recognition Memory: The Effects Of Mental Effort And Similarity On Recollection And Familiarity, Caleb Jordan Picker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Learning new material may retroactively interfere with memory for older material. Retroactive interference research has typically focused on how similarity between old and new material affects recall of old material, which predicts greatest interference when similar material is presented just before test. However, mental effort may be another source of retroactive interference that could disrupt consolidation: Mental effort could cause the most retroactive interference when presented just after study. In Experiment 1, participants engaged in tasks designed to induce mental effort (e.g., solving easy or difficult math problems) at various times between the study and test of an associative recognition …


The Effect Of Sleep On Perceptual Learning And Memory Consolidation, Vanessa Claire Irsik Aug 2015

The Effect Of Sleep On Perceptual Learning And Memory Consolidation, Vanessa Claire Irsik

UNLV Theses, Dissertations, Professional Papers, and Capstones

An ability to segregate speech accurately is essential given that most auditory environments contain other overlapping conversations or environmental noise. While perceiving speech among background noise can be difficult in and of itself, those with hearing impairments can experience considerable difficulty. While training has been shown to benefit perceptual segregation of trained sounds, it is unclear how such training transfers to sounds not included in a training regimen. The current study aimed to address this question by training listeners on a portion of sounds during a vowel segregation task, and subsequently testing on both the trained sounds and untrained sounds. …


Cognitive Features Of Self-Stigmatization Among Juvenile Delinquents, Artyom A. Zinchenko, Mamun Al-Amin, Elena Molchanova Jun 2015

Cognitive Features Of Self-Stigmatization Among Juvenile Delinquents, Artyom A. Zinchenko, Mamun Al-Amin, Elena Molchanova

Journal of Health Disparities Research and Practice

The present study investigates cognitive features of stigmatization phenomenon among juvenile delinquents in Kyrgyzstan. It attempts to describe certain peculiarities of juvenile delinquents’ self-schemas and self-stigmatization. The study, additionally, tackles the issue of currently existing stigmas regarding juvenile delinquency in the country. One hundred and fifty four university students were asked to complete a questionnaire that would measure the level of external stigmatization towards juvenile delinquents and those who were once placed into correctional institution. Students showed presence of stigmatization towards people with a criminal record. Fifteen juveniles from the detention school who attended a socio-psychological training as well as …


Mathematical Models Of Games Of Chance: Epistemological Taxonomy And Potential In Problem-Gambling Research, Catalin Barboianu Jun 2015

Mathematical Models Of Games Of Chance: Epistemological Taxonomy And Potential In Problem-Gambling Research, Catalin Barboianu

UNLV Gaming Research & Review Journal

Games of chance are developed in their physical consumer-ready form on the basis of mathematical models, which stand as the premises of their existence and represent their physical processes. There is a prevalence of statistical and probabilistic models in the interest of all parties involved in the study of gambling – researchers, game producers and operators, and players – while functional models are of interest more to math-inclined players than problem-gambling researchers. In this paper I present a structural analysis of the knowledge attached to mathematical models of games of chance and the act of mathematical modeling, arguing that such …


Experience-Specific And Domain-General Effects On Simple And Complex Meter Processing, Sangeeta Gupta May 2015

Experience-Specific And Domain-General Effects On Simple And Complex Meter Processing, Sangeeta Gupta

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our ability to process rhythmic patterns is constrained by the complexity of its interval structure. The goal of the present study was to explore the cognitive demands and neural mechanisms for processing simple and complex meters, and the extent to which they are modulated by culture-specific experience. The first experiment explored the argument that perception of rhythm is guided by a domain-general ability to process quantity, and that processing simple and complex meter rhythms requires different cognitive strategies. Rhythm perception was assessed by testing listeners’ ability to detect disruptions in simple and complex meter melodies. Proficiency with numerosity judgments was …
