Purpose:

This study is designed to find out what happens in the brain during pregnancy and how this relates to feelings toward the baby and feelings towards pregnancy related body changes. If you are pregnant, you will be forming our population-of-interest group. If you are not pregnant, you are forming our control group. 

What the study involves:

You will visit YNiC for one hour. We will first set up the MEG system. This involves wearing a special helmet that has sensors embedded in it. We use a camera-based system to record the sensor positions and will also place additional sensors on your abdomen. The study will involve independent tasks that will be conducted within the same session each lasting approximately 3 minutes. During two of the tasks, you will be presented with a series of images of infants, some of whom are distressed. You are asked to attend to these images without having to make any responses. In another task you will be presented with images of gratings (dark and light stripes on screen). Again, you will be asked to passively attend to these images. For the remaining tasks you will be asked to close your eyes and attend either to your own thoughts, your own heartbeats. We may repeat some of the tasks if you feel happy to do so. You might be asked to complete these experimental tasks in any order.

Take part in a low-effort, relaxed experiment on body sensations and body image! This study is made up of 2 parts in-person and 1-part online, scheduled for 3 different days. 

Email lucy.stafford@york to take part or sign up via SONA. 

Purpose:

Investigating the link between body sensations and body image. We think this will be informative regarding eating disorders, but first we want to test a non-clinical population- people who are both physically and psychologically healthy. 

What the study involves:

Session 1 (IN-PERSON): For session 1, you need to have eaten two hours before. During the session, you will complete a battery of tasks and questionnaires concerning your body image, body sensations, and eating behaviours . Your weight and height will be measured. An experimenter will measure your waist circumference and shoulder width using a piece of string. This session could take up to 30 minutes.

Session 2 (IN-PERSON): Session 2 will take place 1 day apart from session 1 after 12 hours of overnight fasting from food and any beverages that are NOT water. Please refrain from drinking water 2 hours before session 2 starts. Session 2 will take place in the morning. If you feel faint at any point of the fast, please eat and drink something. During the session, you will drink water from a water bottle to change how your stomach feels and complete a battery of tasks and questionnaires that ask about your body image, body sensations, and how well you think you performed in this experiment. An experimenter will measure your waist circumference using a piece of string. At the end of the session, you will also be asked for your age, ethnicity, gender identity, and highest educational level in a questionnaire on a laptop. This session could take up to 1 hour. 

Session 3 (ONLINE): You will be emailed an online survey to complete a questionnaire about how you feel about the gastric sensations you experience in relation to hunger, satiation, and fullness. This could take up to 10 minutes.

You have been invited to take part because you are 18 years or older and are NOT pregnant and do NOT:

-Have diabetes (type 1 or 2)

-Have a heart condition

-Have a food allergy

-Have a current or historic diagnosis of a gastric disorder or think you might have one.

This study has full ethical approval from the University of York Psychology Ethics Committee (ref: 202417). 

Purpose:

To refine a new scale that has been developed to assess how we feel about sensations that come from our stomach; gastric interoception.

This research has received support with recruitment from Crohn's Disease UK, Crohn's and Colitis UK, SWEDA, The Laurence Trust, Wednesday's Child, National Centre for Eating Disorders, and BodyWhys. The results of this study will be communicated to them once the analysis has been finalised. Many thanks to these organisations for their support! 

What the study involves:

Completing an online survey which asks you for some demographic information, and to fill in questionnaires that ask you about your disorder (if you have one), sensations that come from your body, and sensations that come from your stomach. You will also be asked if you would like to complete the new questionnaire AGAIN a week later.
