Nothing grinds my gears like finding a scale development paper and realizing that the items are NOT PUBLISHED IN THE PAPER.

A figure with two panels
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

Well it's been about a month

I've tracked the number of times Outlook requires me to log in to my email every morning since January 21

Each attempt represents a correct password entered (incorrect entries did not count)

Today holds the record with 38 attempts @microsoft.com

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.

Placebo effect? Potentially…

But side by side glasses from the same bottle of wine, unmistakable difference in taste

My only real explanation is like, high levels of radiation from the plastic or something - but I have no clue, and I don’t have a Geiger counter on me

I need answers

Dear scientific community,

I need answers on the Boće coasters…

Coasters that “encode rainwater frequencies” with “quantum encoded vibrational tunneling” to enhance the flavor of the beverage on the coaster…

Bullshit? Undoubtedly…

Did I taste a difference?… against my will, yes…

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

I'm very excited to announce that our poster won 2nd place at the Fall Voice Conference this past week! Thank you to Jeffrey Girard, Joel Sprunger, and everyone else on the team for this exciting project! #research #voice #ptsd

I’m so grateful for my time here at KU’s Department of Psychology!

I’ve been so lucky to meet some amazing colleagues and friends. I’m looking forward to the next chapter and for the inevitable future collaborations ^_^

The trait theory of voice disorders (TTVD) provided a unified framework to understand these relationships. This study re-examines the TTVD by adopting current theories and methods from personality science.

NEW: Trump lawyers have repeatedly said that the administration is complying with a federal court order stopping it from cutting transgender research funding.

New whistleblower records contradict those claims.

This administration has fired crisis counselors for our veterans and now for kids. This bullshit doesn’t make us great.

Any one of these calls could be life or death for a child. This senseless act of cruelty will kill people and they know it.

NIH bans all future grants to universities with DEI programs or Israel boycotts NIH prohibited the awarding of new grants to institutions that have DEI programs or boycott Israeli companies

So, either universities put their big girl pants on and stand up to Trump

OR

The entire enterprise of biomedical research in the US collapses.
