Character Cues Modulate the Affordance Effects during Danger Warning.

It has been demonstrated that perception of objects automatically evokes potential actions to interact with those objects; this is termed as affordance. The present study investigated how the corresponding affordance effect of graspable objects was modulated by the cue about risk levels of object. Participants were presented with pictures of dangerous graspable objects or neutral graspable objects. The participants were required to perform an upright/upside down discrimination task by pressing different keys. Results showed that both the affordance effects of dangerous object and neutral object in children were enhanced when a cue preceded the object, t(35) = 3.83, p < .01, Cohen's d = 1.29. These results indicate that the prompt of risk level can improve individual's appropriate manipulation to the object.
