The purpose of this study is to evaluate the effect of lifetime self-report physical activity behavior on current cognitive and mental health status in populations of different ages through the lifespan. We will use a digital survey to obtain physical activity behavior reports, including intensity, duration, and physical activity type during several periods of each participant's life, and utilize online cognitive tests and mental health questionnaires to obtain current mental health and cognitive capacity.

Participants will complete an anonymous online survey that asks about their physical activity trends across their lifetime and their current mental health status. The survey will also direct the participants to several brief online cognitive tests. The survey will take approximately 20 minutes to complete. Participants who complete the survey will have the opportunity to fill out a separate form to be entered (via email address) into a drawing to win a $100 prize.

Endometriosis is a common condition that can sometimes affect the nerves and may also impact heart and blood‑vessel health. In this study, we will use routine medical tests that show how the nervous system and cardiovascular system work together. Women with and without endometriosis will go through standard tilt testing - laying still on a table while the head of the table is tilted upward. Blood pressure and heart rate are measured. Participants then wear a blood pressure monitor for 24 hours.

Participants will go through standard tilt testing (laying down on a table that is tilted head up) and 24-hour blood pressure monitoring (wearing a portable blood pressure monitor while going about their day for one day).

This study will assess how healthy adults use vision and light touch at their fingertips (for example, as you might lightly touch a handrail) to help them maintain balance while they walk.

If you agree to participate, we will ask you to come to the lab in Rec Hall on Penn State's campus. First, we will ask you to complete a health history questionnaire, visual assessments, and physical assessments. We will also make measurements of your height, weight, and blood pressure. These assessments will help us determine if you are eligible to continue in the remainder of the study. After screening, if you meet the eligibility criteria, we will ask you to walk on various paths on a virtual reality treadmill under various conditions. Your task will be to walk normally and look forward in each condition. Treadmill walking will take less than an hour and breaks will be given as needed.

Current concussion testing tracks physical symptoms like headaches but often misses psychological factors that can slow down healing. This study asks patients to respond to prompts regarding their injury in three timepoints: acute, sub-acute, and post-acute phases of injury. We will use artificial intelligence to look for specific patterns in their language that might predict a longer recovery. The goal is to create a simple screening tool that helps doctors identify patients who need extra support earlier."

There will be three surveys over the course of one month. Each survey will take around 10-15 minutes.
