Attentional Bias

Dot Probe

In this task, a pair of faces, one threat-related and one either neutral or happy, are shown briefly side-by-side. A small probe replaces one of the faces immediately following offset. Participants are then required to respond as quickly as possible by pressing keys on a keyboard to indicate which face was replaced by a dot without compromising accuracy. The face stimuli are usually photographs of 16 different individuals (8 male, 8 female) taken from the NimStim set.

Note: The Dot Probe is administered to children and adults ages 6-85 years old.
