Christina Nelson - Applying John Hagan’S Power-Control Theory To Gender Differences With Drug Abuse, Christina Nelson
Ronald E. McNair Scholars Program 2014
Previous work has indicated that young men and women engage in drug use in different ways and for different reasons. This research tests Hagan’s Power-Control Theory to examine gender differences in adolescent drug use. This study analyzes randomly selected subsample of data from the National Survey on Drug Use and Health (NSDUH). Questions that led this study were: Do patterns of drug abuse differ by gender? To what extent can Hagan’s Power-Control Theory explain this? Control variables looked at gender, age and race. All adolescents were from the ages of 12-17. Dependent variables looked at drug use (ever, yearly, monthly). …

The broad objective of this line of research is to understand how auditory feedback manipulations may be used to elicit involuntary changes in speech articulation. We examine speech sensorimotor adaptation to supplement the development of speech rehabilitation applications that benefit from this learning phenomenon. By manipulating the acoustics of one’s auditory feedback, it is possible to elicit involuntary changes in speech articulation. We seek to understand how virtually manipulating participants’ perception of vowel space affects their speech movements by assessing acoustic variables such as formant frequency changes. Participants speak through a digital audio processing device that virtually alters the perceived …
