How insomnia affects recognizing facial emotions and emotional regulation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with chronic insomnia and matched control participants will complete two facial emotion recognition tasks: one explicit test with unlimited viewing time and one implicit test using eye-tracking to measure attentional biases and fixation patterns. Results from the insomnia and control groups will be compared to identify differences in emotion recognition accuracy and gaze behavior. Participants will also complete the Cognitive Emotion Regulation Questionnaire (CERQ) to relate recognition performance to emotional regulation profiles. Data are collected in person at the hospital and entered into an anonymized database for analysis.
