Impulsivity in College Students with and without ADHD
Miller, Jessica A.
ProQuest LLC, Au.D. Dissertation, James Madison University
Impulsivity is the cardinal symptom of ADHD. It is estimated that ADHD is present in eighteen percent of children and in four percent of adults. The present study repeats and extends a previous study (Gray, Breier, Foorman, & Fletcher, 2002) that measured impulsivity in adolescents with and without ADHD, which found higher false alarm rates (impulsivity) in subjects with ADHD when listening with a moderately unpredictable background masker. In the present study, participants were adults: 31 university students (14 in an experimental group with a diagnosis of ADHD or complaints of distractibility and 17 in a control group). As in the previous study, a single-interval, maximum-likelihood method was used to estimate thresholds of pure tone signals in three different types of masking tasks (quiet, central masking, and informational masking). False alarm rates were measured as an assessment of impulsivity. No statistically significant differences were found between the false alarm rates or thresholds between the experimental and control subjects. This suggests that these adult students have either developed meta-cognitive skills to overcome the symptoms of ADHD or that they have out grown of their ADHD symptoms.
