Abstract
The attentional model of time estimation assumes that specific chronometric mechanisms are involved in the processing of temporal information. The two experiments reported here provide evidence in favour of this model. The first study, which uses the method of attentional sharing in a dual-task paradigm (discrimination of the intensity and die duration of a visual stimulus), shows that controlled attention can be applied to the processing of temporal information and that subjective duration shortens when the attention paid to time decreases. The second one, by comparing brain activities recorded during a temporal and a nontemporal tasks, suggests that certain prefrontal areas are involved in temporal processing.
