A researcher investigated whether individuals diagnosed with Generalized Anxiety Disorder (GAD) demonstrate a stronger attentional bias towards threatening stimuli than individuals without GAD. A matched pairs design was used, involving 15 participants diagnosed with GAD and 15 participants without GAD. The researcher measured the response times (in milliseconds) of each participant when responding to threatening words presented on a computer screen. It was found that participants with GAD were significantly faster at identifying the location of threatening words compared to those without GAD.
