Summary
Individuals at risk for eating disorders process fat-related words faster than unrelated words. This finding offers insights into information processing in eating disorder development.
Area of Science:
- Cognitive Psychology
- Clinical Psychology
- Neuroscience
Background:
- Eating disorders are complex mental health conditions.
- Information processing biases are implicated in the development and maintenance of eating disorders.
- Lexical processing of threat-related stimuli is a key area of research.
Purpose of the Study:
- To investigate the effect of eating disorder risk on lexical processing of fat-related words.
- To compare word processing speeds between individuals at risk for eating disorders and healthy controls.
- To explore the role of cognitive biases in eating disorder pathology.
Main Methods:
- A lexical decision task was employed.
- Participants included individuals at risk for eating disorders (n=17) and controls (n=31).
- Stimuli included fat-related words, unrelated words, neutral words, and pseudowords.
Main Results:
- A significant Group x Stimuli interaction was found for reaction times.
- Individuals at risk for eating disorders demonstrated faster processing of fat-related words compared to unrelated words.
- This effect was not observed in the control group.
Conclusions:
- Individuals at risk for eating disorders exhibit enhanced lexical processing of fat-related stimuli.
- Cognitive models of information processing may help understand eating disorder development.
- These findings highlight the importance of attentional biases in eating disorder research.
