This study looks at the relationship between motor control via. arm movement and visual stimuli. After participating in brief calibration protocol for the eye tracking system, participants will be moving a robotic handle to interact with visual stimuli during various tasks. Participants will spend approximately 2 hours in the lab.

There will be one approximately 2-hour visit. They will then be asked to complete 20-25 blocks of hand movements while looking at a moving virtual stimulus with a large visual background. Participants will receive regular breaks during the experiment.

The purpose of this study is to define how eye movements contribute to eye-hand coordination in individuals of the age group 18-50 (young adults) and 65-80 (older adults). Specifically, the aim of the study is to understand how slow eye movements affect arm and hand movements. All procedures to be used in our study will be non-invasive. The task during the study will be performed with a robotic handle that participants will grasp with their right hand. They will interact with visual stimuli by moving the robotic handle. The robotic environment will attempt to simulate real-world mechanical interactions, such as those experienced during catching a ball.

During this study, we will ask you to come to our laboratory located in 23 Recreation Building, Pennsylvania State University, on two days separated by a maximum of 48 hours. Both sessions will last approximately 90-120 minutes. During the first session, we will review the procedures with you and if you agree to participate, you will sign this form and then proceed to perform the study. You will perform about 20-25 blocks of hand movements. Each block will consist of 24-30 trials and each trial will last between 3-5 seconds.The second day will be identical to the first day but the order of trials within a block will be changed.

In this project, participants will perform experiments where they will be asked to look at salient virtual targets and make reaching movements to those targets, while ignoring other visual stimuli presented to them.

During this study, we will ask you to come to our laboratory located in 23 Recreation Building, Penn State University, on a single day.We will ask you to perform an eye-hand coordination task using a robot. You will sit in a modified chair and grasp a handle that permits you to move your hand leftward, rightward, towards and away from your body. A display system will project visual targets into the same plane as your hands, which will allow you to interact virtually with the visual targets. These targets will be either bright or dark and you will be instructed to look at some of these targets (while ignoring others) and make reaching movements to some of these targets.

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.

Participants will complete simple online tasks, for example judging differences in auditory pitch; processing visual and auditory stimuli in congruent and incongruent pairings; rating the sound-symbolic properties of either real words, pseudowords, or both; or discriminating between two stimuli on the basis of their structural properties over a change in their surface properties, and vice versa.

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.

Participants will perform simple behavioral tasks either stand-alone or while being scanned; they may also complete questionnaires or rating scales.

This study is about investigating how certain elements of urban configuration affects people's subjective perception of noise in urban environments. This section of the study assesses participants' subjective reactions to noise intensity when the tree density changes in various spaces.

This study looks at how people use their eyes and body to interact with moving objects while standing up. Participants will stand at a robotic device and try to stop virtual objects moving at different speeds on a screen, similar to catching or blocking a ball. The research will help us understand how the brain coordinates sensory information to maintain balance.

Participants will be required to stand and interact with virtual objects by grasping a robotic manipulandum. A session will last approximately 120 minutes.

Using small focus groups, this work aims to understand the experiences, challenges, perceptions, and opportunities for the use of conversational agents (e.g Amazon Alexa and Siri) for users with visual or hearing impairments, with the goal of developing more accessible and inclusive systems.

How does the brain decide to reach one way or the other? This study will examine how movement decisions are coordinated by neural mechanisms in the brain during manual interception and reaching actions.

Participants will be required to complete a simple virtual interception task with a handle. Participants will be screened and sign informed consent upon entry of the lab. They will then be fitted with EMG sensors and an eye-tracking reference sticker. They will be seated for this task. The task requires a participant to hold their hand steady at the epicenter of a circle, and reach as quickly and accurately as possible to one of 2 moving targets that will appear.

This study explores how the brain, eyes, and muscles work together when people use their hands to track or catch moving objects. Participants will sit and use their right hand on a tablet to follow a moving virtual ball while wearing non-invasive sensors that record brain waves (EEG), muscle activity (EMG), and eye movements. The goal is to understand how the body prepares for and responds to motion using vision and movement control. The findings may help scientists improve therapies and technologies for people with movement difficulties, such as after a stroke or brain injury.

Participants will attend one in-person session lasting approximately 2 hours. During the session, they will wear an EEG cap, EMG sensors, and an eye tracker while completing a hand-tracking task using their right hand on a tablet.

The study aims to quantify the effects of blue-enriched white light on cognitive performance.

There will be only one visit where participants will complete cognitive tasks and subjective evaluations of the indoor experimental space.

The purpose of this study is to explore outdoor lighting and its environmental impact, focusing on human perception of these factors. Participants will undergo various tests to evaluate their subjective and objective responses to different light levels and chromaticities.

Participants will complete a demographic survey, will undergo screening tests to assess their visual acuity. If eligible, they will evaluate various lighting environments through a questionnaire and complete an object detection test before and after a brief training session. The total duration of the experiment will be approximately 1 hours.
