A Pilot Laboratory Study Investigating How Physical Tasks and Hunger Affect Taste Perception

Study Overview
=================
Brief Summary
-----------------
This one time pilot laboratory study focuses on examining the relationship between different types of physical tasks and taste perception of high and low-calorie foods among hungry individuals.

Official Title
-----------------
A Pilot Laboratory Study Investigating How Physical Tasks and Hunger Affect Taste Perception

Conditions
-----------------
Food Consumption, Perseverance

Intervention / Treatment
-----------------
* Behavioral: Simple physical task
* Behavioral: Complex physical task
* Other: Cookies
* Other: Vegetables
* Behavioral: No physical task


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Willing to travel to laboratory around lunchtime for the study Willing to abstain from eating and drinking caloric beverages for at least 4 hours prior to completing the study Typically eats lunch Exclusion Criteria: Diabetes, eating disorder, or any other condition that makes it unadvisable for participant to refrain from eating or drinking caloric beverages for 4 hours. Food allergies that would prevent participants from eating chocolate chip cookies or vegetables Pregnant or lactating Typically goes for longer than 5 hours (not counting sleep time) between meals and snacks Physical disabilities that would make it difficult for the participant to walk or to use their hands to grasp objects

Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: No physical task + Taste cookies<br>Participants in this arm do not engage in a physical activity task. They are asked to taste test chocolate chip cookies. | Other: Cookies<br>* Participants are asked to taste test chocolate chip cookies<br>Behavioral: No physical task<br>* As a control, for 2 of the arms, participants are not asked to engage in a physical task<br>|
| Active Comparator: No physical task + Taste vegetable<br>Participant does not complete a physical activity. Asked to taste test raw celery or radishes. | Other: Vegetables<br>* Participants are asked to taste test raw celery or radishes<br>Behavioral: No physical task<br>* As a control, for 2 of the arms, participants are not asked to engage in a physical task<br>|
| Active Comparator: Simple physical task + Taste vegetables<br>Participants are asked to complete a simple physical task and are asked to taste test raw celery or radishes. | Behavioral: Simple physical task<br>* Participants are asked to complete a 1-time simple physical task that is not challenging nor novel (moving small objects across a room).<br>Other: Vegetables<br>* Participants are asked to taste test raw celery or radishes<br>|
| Active Comparator: Complex physical task + Taste vegetables<br>Participants complete a more complex physical task that is novel and challenging. They are asked to taste test raw celery or radishes. | Behavioral: Complex physical task<br>* Participants are asked to complete a 1-time physical task that is low intensity but somewhat complex (involves a novel request to move objects in a way that is challenging and requires some coordination).<br>Other: Vegetables<br>* Participants are asked to taste test raw celery or radishes<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| physical perseverance | as measured via maintained grip using a hand dynamometer on the dominant hand and set to 70% of participant's maximum grip strength | 1 hour | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| food preference | Food preference measured via participant's reported ratings after tasting different food. | 1 hour | 
| Amount of food eaten | Amount of food that participants eat will be measured via a food scale at the end of the study. | 1 hour | 
| Mood | Participant's subjective mood will be measured using a mood questionnaire (PANAS). | 1 hour |
