Abstract(s) :

(Anglais) Current cognitive models postulate that attention can be distinguished into separate networks that execute discrete attentional functions. The ‘alerting’ network elicits a vigilant state, the ‘orienting’ network selects relevant information from the environment, and the ‘conflict monitoring’ network resolves competition between alternative responses. Children anxiety has been characterised by attention biases, meaning a preferential allocation of attention resources towards threatening information and we postulate that these biases may involve a specific pattern of attention network impairments. To evaluate this hypothesis, we submitted fifteen children with primary diagnosis of anxiety disorders and fifteen healthy control children matched on age, gender and education level to an adapted version of the Attention Network Test in which they are asked to indicate the gaze direction of a fish or a human face that alternatively displays a neutral, angry or happy expression. These targets may be preceded by cues indicating where the stimuli to detect will appear, and may be flanked by other stimuli looking into the same or the other direction. We measured reaction times and response accuracy. Results showed no influence of anxiety on the three networks when targets were non-emotional. However, anxious children showed faster RT in response to angry faces without warning cues, and did not use the spatial cue to orient their attention towards these stimuli faster. These results suggest that anxious children demonstrated functional impairments in the alerting and orienting attention networks when processing emotional stimuli, without influence of anxiety on the conflict monitoring process.
