During speech, the brain is constantly processing and monitoring speech output through the auditory feedback loop to ensure correct and accurate speech. If the speech signal is experimentally altered/perturbed while speaking, the brain compensates for the perturbations by changing speech output in the opposite direction of the perturbations. In this study, we designed an experiment that examined the compensatory responses in response to unexpected vowel perturbations during speech. We applied two types of perturbations. In one condition, the vowel /ɛ/ was perturbed toward the vowel /æ/ by simultaneously shifting both the first formant (F1) and the second formant (F2) at 3 different levels (.5=small, 1=medium, and 1.5=large shifts). In another condition, the vowel /ɛ/ was perturbed by shifting F1 at 3 different levels (small, medium, and large shifts). Our results showed that there was a significant perturbation-type effect, with participants compensating more in response to perturbation that shifted /ɛ/ toward /æ/. In addition, we found that there was a significant level effect, with the compensatory responses to level .5 being significantly smaller than the compensatory responses to levels 1 and 1.5, regardless of the perturbation pathway. We also found that responses to shift level 1 and shift level 1.5 did not differ. Overall, our results highlighted the importance of the auditory feedback loop during speech production and how the brain is more sensitive to auditory errors that change a vowel category (e.g., /ɛ/ to /æ/).

Due to the COVID-19 pandemic, declared in March of 2020, there have been many lifestyle changes which have likely influenced tobacco smoking behavior. Such lifestyle changes include lockdowns, stay at home orders, reduction in social cues related to smoking, increased stress, and boredom among other things. This study utilized a cross-sectional survey which looked into these behaviors, primarily perceived risk to COVID-19, and determined if there is an association between perceived risk and education level/race. Education level is a proxy for income and material resources, therefore making it more likely that people with lower levels of education have fewer resources and higher perceived risk to negative effects of COVID-19. Additionally, people of color are often marginalized in the medical community along with being the target of heavy advertising by tobacco companies which have likely impacted risk to COVID-19 as well.

The purpose of this longitudinal study was to predict /r/ acquisition using acoustic signal processing. 19 children, aged 5-7 with inaccurate /r/, were followed until they turned 8 or acquired /r/, whichever came first. Acoustic and descriptive data from 14 participants were analyzed. The remaining 5 children continued to be followed. The study analyzed differences in spectral energy at the baseline acoustic signals of participants who eventually acquired /r/ compared to that of those who did not acquire /r/. Results indicated significant differences between groups in the baseline signals for vocalic and postvocalic /r/, suggesting that the acquisition of certain allophones may be predictable. Participants’ articulatory changes made during the progression of acquisition were also analyzed spectrally. A retrospective analysis described the pattern in which /r/ allophones were acquired, proposing that vocalic /r/ and the postvocalic variant of consonantal /r/ may be acquired prior to prevocalic /r/, and /r/ followed by low vowels may be acquired before /r/ followed by high vowels, although individual variations exist.

Ecological modeling can be used to analyze health risk behaviors and their relationship to ecological factors, which is useful in determining how social environmental factors influence an individual’s decisions. Environmental interactions shape the way that humans behave throughout the day, either through observation, action, or consequences. Specifically, health risk behaviors can be analyzed in relation to ecological factors. Alcohol drinking among college students has been a long concern and there are many risks associated with these behaviors in this population. Consistent engagement in health risk behaviors as a college student, such as drinking and smoking, can pose a much larger issues later in life and can lead to many different health problems. A research study was conducted in the form of a 27 question survey to determine and evaluate the impact of ecological factors on drinking and smoking behaviors among Arizona State University students. Ecological factors such as demographics, living conditions, contexts of social interactions, and places where students spend most of their time were used to evaluate the relationship between drinking and smoking behaviors and the ecological factors, both on- and off- campus.

The Ryan House Family Survey is used to assess family satisfaction of the respite services used. Over the last two years, the number of responses has been less than desired. This project used stakeholder interviews and peer reviewed literature to create a recommendation of how to effectively gather the most relevant information. The survey is currently ten questions and averages three minutes to take. It asks families to rate their satisfaction with different aspects of their stay. Some of these are scheduling, coordination of medical orders, and the intake process. The results of this evaluation will allow the staff at Ryan House to be assured in the care that they are providing, make improvements where needed, and give the organization data to use on a public platform.

Purpose: The purpose of this study was to determine the effectiveness of parent training in Enhanced Milieu Teaching with Phonological Emphasis (EMT+PE) using telepractice on the speech and language outcomes of children with cleft lip and/or palate (CL/P).

Method: Three parent-child dyads participated in the study. All child participants had nonsyndromic CL/P and ranged in age from 21 to 27months. Participants received three weekly telepractice intervention sessions, along with a total of three in-person parent training sessions. Intervention and training were conducted by an SLP and trained graduate student.

Results: All speech measures indicated a gain in essential speech skills for all three children when comparing pre-intervention to post-intervention assessment results. Positive improvement was seen across multiple language measures for all participants.

Conclusion: A parent implemented EMT+PE intervention program using telepractice is an effective way to increase child speech and language outcomes for children with CL/P. Speech and language targets should be combined and delivered simultaneously in intervention.

The purpose of this study was to compare the speech and motor functions a group of individuals with Childhood Apraxia of Speech (CAS) and a case study of an individual who has suffered a right cerebellar stroke. The participants consisted of one case study adult and three families made up of three to five members each, all with a history of CAS. All of the participants in the study performed below average on speech and motor function tests. There are some comparable similarities between the CAS group and the case study individual suggesting that there is cerebellar involvement in the fine motor skills needed to perform speech movements.

College students are constantly stressed while balancing their coursework, personal life, relationships, jobs, and more. Whether they are in their last year trying to apply for jobs or post graduate programs or first-year students trying to acclimate to a new environment and a heavier course load, college students are under significant pressure. Stress can lead to deteriorating health habits including oral hygiene. To understand the relation between stress and oral hygiene among college students, this study explores selected students in Arizona and how their oral health has changed since starting college. In a survey of current Arizona State University students, the findings suggest there is a lack of oral health habits within the population and a misunderstanding of what constitutes proper oral hygiene. The study investigated health habits such as diet, exercise, and oral hygiene and how they correlated with the conceptions people had about what is considered correct oral care. Although oral care is extremely important, the conclusions indicate that educated populations, like college students, have not prioritized correct hygiene practices. The lack of oral health in college students can lead to further health problems highlighting the importance to promote proper oral hygiene practices.
