This study delves into the influence of satiety on cognitive control (our thoughts and actions) and its implications for food-related behaviors. While previous research predominantly talked about the cognitive ramifications of hunger, in this study, we are reforming the spotlight on how we react when we are comfortably full. According to Cohen's small-size effect, the sample will be 216 volunteers. We will measure each participant's reaction time on the stop signal task, showing neutral valence words and pictures (food pictures-modal, food words-amodal, neutral pictures-modal, neutral words-amodal).
Expected outcomes include predictions that satiated individuals have lower inhibitory control (longer SSRT), no matter what the words or pictures are about. Furthermore, we hypothesize that there is no significant difference when individuals are satiated on inhibitory control regardless of visual and verbal stimuli (content-wise). Additionally, we are interested in examining whether the impact of satiety on inhibitory control is consistent across different types of neutral stimuli regardless of their format.
The statistical analysis will involve repeated measure ANOVA to examine the main effects and interactions of stimulus type and content on stop signal reaction times. Post hoc analysis will be used to determine the significant findings in detail.
Our study objective is to focus on how feeling satiety influences our brain control process and helps provide us with a better understanding of our eating behaviors and develop strategies to help people with eating disorders.
