Study driver situation awareness and behavior in connected and autonomous vehicles with a driving simulator

This is a behavioral study that will examine the effect of different message designs and driver characteristics on driver situation awareness and driving behavior in connected and autonomous vehicles. The driving simulator will be used to simulate various traffic events in connected and autonomous vehicle environments. All you need to do is driving on a driving simulator or watch driving scenarios online and complete questionnaires. The online pilot study will take about 1.5 hours. The in-person simulator study in lab will take 5 minutes for a pre-screening survey and 2 hours for the experiment.

Development of Lighting Application Efficacy Measurement Framework

This study seeks to analyze how subjects perceive brightness in a space. For this purpose, two separate studies will be conducted in a real setting in the Lighting Lab. In one experiment, subjects will be asked to judge the brightness of a task surface under different lighting conditions, which will be generated automatically, by assigning a value to the brightness level. In the other experiment, subjects will be asked to compare various automatically generated lighting conditions in side-by-side bays and adjust the lighting using a dial knob in one of the bays to match the light level in the other one in each condition.

Evaluating the consequences of mistimed light-emitting device use on cardiac activity and sleep health

The study is being done to find out whether wearing blue light-blocking glasses in the evening improves subsequent sleep. This is a 21-day study where participants will be asked to wear a sleep-monitoring “actiwatch” and an activity monitor, as well as to provide screenshots of their smartphone’s screen time app for three weeks. Participants will also be asked to wear a heart tracker on their wrist and a blood pressure cuff on their arm for three days during the second and third week, for a total of six days.

The role of middle temporal and frontoparietal areas in limb motor control

The goal of this research is to understand the role of motion-processing areas on limb motor control. We will be using behavioral studies and combining that with functional brain imaging, EEG, and non-invasive brain stimulation using transcranial magnetic stimulation (TMS). TMS has been used in thousands of studies and is a very safe method to understand brain function for eye hand coordination.

Investigating Face Processing Behavior and Neural Circuitry

The ability to recognize faces differs across people. We are studying this variability in behavior and in brain responses in young adults (ages 18-25 years) in the Lab of Developmental Neuroscience at Penn State. If eligible, you will do face recognition tasks on the computer and answer survey questions. You may also be asked to participate in another session in which we take pictures of your brain using MRI. Volunteers are paid $10/hr for time in the lab. Interested participants can start the screening processing by clicking on this confidential screening link here: https://pennstate.qualtrics.com/jfe/form/SV_9NPJ20bQAPd0VKZ

A SINGLE-CENTER, DOUBLE-ARM, PROSPECTIVE CLINICAL TRIAL TO COMPARE VISUAL PERFORMANCE OF NON-DIFFRACTIVE EXTENDED DEPTH OF FOCUS AND NEUTRAL ASPHERIC MONOFOCAL INTRAOCULAR LENSES

Compare the vision of subjects that receive one of two FDA approved intraocular lenses (IOLs) in both eyes, the Alcon Vivity or Bausch & Lomb enVista. You will be followed by research, 1 and 3 months after your second cataract surgery is performed.

Defining the role of slow eye movements on limb motor control

The purpose of the study is to examine how slow eye movements called smooth-pursuit eye movements, contribute to hand-eye coordination. Participants will grasp a robotic manipulandum and using the manipulandum interact with virtual visual stimuli in an augmented-reality environment.

Functional magnetic resonance imaging (fMRI) and psychophysical studies of sensory perception and cognition

The purpose of this study is (1) to understand how the brain processes sensory information and (2) how this is affected by factors like blindness or synesthesia. In addition to behavioral testing, the study will use functional magnetic resonance imaging (fMRI) which enables us to take pictures of the brain while you are doing a task, using an instrument called an MRI scanner.

Characterizing the Visual Pathway in Epilepsy

This research is being done to determine whether the way your brain processes vision is involved in the epilepsy disease process. There has been recent evidence suggesting that epilepsy patients, compared to healthy controls, have thinner retinas, specifically a layer called the retinal nerve fiber layer, the inner most layer of the retina. This study will expand on that finding by investigating any differences in all of the retinal layers, as well as visual function, between epilepsy patients and healthy controls.
