So pretty excited about Fall Voice this year‼️‼️ 1 podium accepted and *won an award* for being the best measurement / outcomes science abstract submitted 2 posters accepted And also now an invited speaker for the Advanced Track SLP course to discuss our work into laryngoresponders 😊😊

As a professor at the University of Houston who’s fascinated by sociolinguistics… I spend WAY too much energy paying attention to whether people say “U of H” or “U H” I know there’s not a “right” answer but I’m still trying to figure out why people choose one over the other

I never walked my PhD graduation, so I never got hooded Two years later, hopped onto a boat with my advisor, and got hooded where the Ohio, Allegheny, and Monongahela Rivers join in front of the iconic Pittsburgh skyline - much cooler experience than getting hooded on stage

Which leads to the main finding: Empirically derived phenotypes nested within each disorder outperformed the DSM-defined constructs. Constructs derived from patterns of symptom covariation grouped individuals with more similar symptoms, and may get us closer to underlying mechanisms.

Construct-focused heterogeneity (left) and person-focused heterogeneity (right) scores for each disorder and the empirically derived phenotypes nested within each disorder. Higher scores indicate greater heterogeneity, and empirically derived phenotypes consistently have lower heterogeneity than their parent DSM-defined disorder, with narrower phenotypes showing greater improvements.

Top panel: line plot over time with x-axis beginning on January 21 through February 20. The height of the dots correspond to the Number of Correct Password Entries (y-axis), and has an additional line representing a smoothing function over time

Bottom panel: A histogram with an overlaid density distribution line to represent the number of correct password entries required, with most of the histogram distribution being between 1-10, with several notable outliers above 15 and all the way to almost 40

I mean, to be fair to them, it truly would be a "new era of discovery in brain research" if it turns out we've been wrong all this time about which direction the brain is facing in the skull.

Scientific Poster: Acoustic Features of Post-Traumatic Stress Disorder in a Non-Voice-Disorder Sample

Heading: People with PTSD demonstrate increased vocal hyperfunction (lower H1-H2) and decreased pitch variability compared to people who have experienced a traumatic event but do not have PTSD

Background: Experiencing a traumatic event sometimes precedes the onset of primary muscle tension dysphonia
(MTD). However, our clinical understanding of voice-trauma relationship is largely informed by working with patients seeking treatment after they develop a problem with their voice. This study examines the acoustic features of people
diagnosed with (n = 52) and without (n = 40) post-traumatic stress disorder (PTSD), all of whom have experienced a
DSM-5 Criterion A traumatic event and are not seeking treatment for problems with their voice.

Plot 1) Dot and whisker plot - All participants exhibited lower CPPS
during the Impact Statement

Plot 2) Dot and whisker plot - People with PTSD demonstrated significantly lower H1-H2 scores compared to controls, especially during the Impact Statement

Plot 3) Dot and whisker plot - People with PTSD demonstrated significantly less pitch variability on both tasks compared to controls

Methods:
Two groups, all of whom experienced a DSM-5 Criterion A traumatic event; n=52 diagnosed with PTSD, n=40 not diagnosed with PTSD

Both groups provided two 10-min recording task - 1) trauma account, describing the event in detail; 2) Impact statement, describing how this event has since impacted their life (beliefs, relationships, etc)

Audio files were processed and extracted CPPS, H1-H2, & SD pitch

Discussion: Although all participants experienced a traumatic event, people with PTSD exhibited lower H1-H2, an acoustic correlate of increased vocal hyperfunction. These findings provide novel insight into a putative pathway from a traumatic event to developing MTD, by way of habituating phonatory behaviors associated with vocal hyperfunction
