Description
An increasing number of military veterans are enrolling in college, primarily due to the Post-9/11 GI Bill, which provides educational benefits to veterans who served on active duty since September 11, 2001. With rigorous training, active combat situations, and exposure to unexpected situations, the veteran population is at a higher risk for traumatic brain injury (TBI), Post Traumatic Stress Disorder (PTSD), and depression. All of these conditions are associated with cognitive consequences, including attention deficits, working memory problems, and episodic memory impairments. Some conditions, particularly mild TBI, are not diagnosed or treated until long after the injury when the person realizes they have cognitive difficulties. Even mild cognitive problems can hinder learning in an academic setting, but there is little data on the frequency and severity of cognitive deficits in veteran college students. The current study examines self-reported cognitive symptoms in veteran students compared to civilian students and how those symptoms relate to service-related conditions. A better understanding of the pattern of self-reported symptoms will help researchers and clinicians determine the veterans who are at higher risk for cognitive and academic difficulties.

Description
The increase of Traumatic Brain Injury (TBI) cases in recent war history has increased the urgency of research regarding how veterans are affected by TBIs. The purpose of this study was to evaluate the effects of TBI on speech recognition in noise. The AzBio Sentence Test was completed for signal-to-noise ratios (S/N) from -10 dB to +15 dB for a control group of ten participants and one US military veteran with history of service-connected TBI. All participants had normal hearing sensitivity defined as thresholds of 20 dB or better at frequencies from 250-8000 Hz in addition to having tympanograms within normal limits. Comparison of the data collected on the control group versus the veteran suggested that the veteran performed worse than the majority of the control group on the AzBio Sentence Test. Further research with more participants would be beneficial to our understanding of how veterans with TBI perform on speech recognition tests in the presence of background noise.

Description
This thesis investigated the impact of word complexity as measured through the Proportion of Whole Word Proximity (PWP; Ingram 2002) on consonant correctness as measured by the Percentage of Correct Consonants (PCC; Shriberg & Kwiatkowski 1980) on the spoken words of monolingual Spanish-speaking children. The effect of word complexity on consonant correctness has previously been studied on English-speaking children (Knodel 2012); the present study extends this line of research to determine if it can be appropriately applied to Spanish. Language samples from a previous study were used (Hase, 2010) in which Spanish-speaking children were given two articulation assessments: Evaluación fonológica del habla infantil (FON; Bosch Galceran, 2004), and the Spanish Test of Articulation for Children Under Three Years of Age (STAR; Bunta, 2002). It was hypothesized that word complexity would affect a Spanish-speaking child’s productions of correct consonants as was seen for the English- speaking children studied. This hypothesis was supported for 10 out of the 14 children. The pattern of word complexity found for Spanish was as follows: CVCV > CVCVC, Tri-syllables no clusters > Disyllable words with clusters.
