Description
Previous studies have found that the detection of near-threshold stimuli is decreased immediately before movement and throughout movement production. This has been suggested to occur through the use of the internal forward model processing an efferent copy of the motor command and creating a prediction that is used to cancel out the resulting sensory feedback. Currently, there are no published accounts of the perception of tactile signals for motor tasks and contexts related to the lips during both speech planning and production. In this study, we measured the responsiveness of the somatosensory system during speech planning using light electrical stimulation below the lower lip by comparing perception during mixed speaking and silent reading conditions. Participants were asked to judge whether a constant near-threshold electrical stimulation (subject-specific intensity, 85% detected at rest) was present during different time points relative to an initial visual cue. In the speaking condition, participants overtly produced target words shown on a computer monitor. In the reading condition, participants read the same target words silently to themselves without any movement or sound. We found that detection of the stimulus was attenuated during speaking conditions while remaining at a constant level close to the perceptual threshold throughout the silent reading condition. Perceptual modulation was most intense during speech production and showed some attenuation just prior to speech production during the planning period of speech. This demonstrates that there is a significant decrease in the responsiveness of the somatosensory system during speech production as well as milliseconds before speech is even produced which has implications for speech disorders such as stuttering and schizophrenia with pronounced deficits in the somatosensory system.

Description
Early adolescence is a pivotal stage of social and emotional development. Socialization traditionally occurs in person, but social interactions via technology (e.g., social media, video games) have grown in popularity. However, little research has been conducted on how early adolescents interact with technology and how these interactions relate to their socialization as well as other factors such as reading habits or academic achievement. Seventh and eighth grade students (n = 719) completed a survey that captured information about their technology use, their academic habits and performance, and extracurricular involvement. It was hypothesized that those involved in more extracurricular activities would use the internet more socially and that internet use would be negatively correlated to both academic performance and recreational reading. Responses indicated that a majority of students have access to technology (e.g. internet, computers, television, gaming consoles, and tablets) in their homes. Social media use differed drastically between platforms. Analyses indicated a relation between amount of extracurricular activities on social television watching and social internet use, but not on social gaming. A significant negative correlation was found between recreational reading and time spent socializing online, but there was no significant effect of these factors on academic performance. Thus, hypotheses were partially supported by the relation between amount of extracurriculars and social internet use and the negative correlation between time spent socializing online and recreational reading.

Description
In previous research, Luthar and Barkin (2012) found that across three different samples collected from three high-achieving schools, adolescents reported elevated rates of maladjustment behaviors, which include substance use, and internalizing and externalizing symptoms. Additionally, past research has also indicated that these maladjustment behaviors are related to parent relationships. A group of high-achieving adolescents that research has not yet focused on are those attending boarding schools, who may have higher-quality relationships with parents due to less daily strife. This study aimed to examine high-achieving adolescents across five samples from five high schools, two of which were boarding schools. This study hypothesized that the high-achieving adolescents attending both boarding schools would report lower rates of substance use, internalizing and externalizing symptoms, and lower rates of perceived parent criticism and expectations in comparison to those attending the day schools. Substance use, internalizing and externalizing symptoms, and parent relationships were measured using self-report measures that were completed by students attending these schools. Results showed that both boarding schools reported elevated rates of substance use in comparison to the three day schools and these rates measured above national norms. At the same time, both boarding schools reported lower rates of internalizing and externalizing symptoms when compared to rates reported by the day school students. This study also found that there were differences among parent relationship measures, such as criticism and expectations, among all school samples. Results of this study also showed that aspects of parent relationship, such as parent knowledge, were associated with rates of substance use among all school samples. In summary, boarding school students showed elevated substance use, similar parental relationship quality, and lower mental health symptoms compared to day school students. For all students, some aspects of the parental relationship were related to levels of substance use.

Description
Cochlear implant (CI) successfully restores hearing sensation to profoundly deaf patients, but its
performance is limited by poor spectral resolution. Acoustic CI simulation has been widely used
in normal-hearing (NH) listeners to study the effect of spectral resolution on speech perception,
while avoiding patient-related confounds. It is unclear how speech production may change with
the degree of spectral degradation of auditory feedback as experience by CI users. In this study,
a real-time sinewave CI simulation was developed to provide NH subjects with auditory
feedback of different spectral resolution (1, 2, 4, and 8 channels). NH subjects were asked to
produce and identify vowels, as well as recognize sentences while listening to the real-time CI
simulation. The results showed that sentence recognition scores with the real-time CI simulation
improved with more channels, similar to those with the traditional off-line CI simulation.
Perception of a vowel continuum “HEAD”- “HAD” was near chance with 1, 2, and 4 channels,
and greatly improved with 8 channels and full spectrum. The spectral resolution of auditory
feedback did not significantly affect any acoustic feature of vowel production (e.g., vowel space
area, mean amplitude, mean and variability of fundamental and formant frequencies). There
was no correlation between vowel production and perception. The lack of effect of auditory
feedback spectral resolution on vowel production was likely due to the limited exposure of NH
subjects to CI simulation and the limited frequency ranges covered by the sinewave carriers of
CI simulation. Future studies should investigate the effects of various CI processing parameters
on speech production using a noise-band CI simulation.

Education and Prevention: An Open Communication Against the Sexual Abuse and Grooming of Adolescents
Description
With the assistance of my thesis committee, I created a podcast to fulfill my objective of interviewing survivors of sexual abuse/grooming practices and their support systems. I utilized this method to have in-depth discussions and provide people with a safe space to share their experiences. By doing so, we were able to reflect on the areas in which professionals can improve on recognizing signs of abuse in their communities. My goal was to show how training teachers to recognize signs of trauma is essential for effectively assisting the population we serve. Ultimately, this came down to what instruction was taught in the Teachers College. Curricula centered on properly managing trauma in the classroom, including sexual abuse, should be required for courses in the upper and lower division degree program for Mary Lou Fulton Teachers College.
