    Abstract
    The habituation to intense acoustic stimuli and the acquisition of differentially conditioned fear were assessed in 53 clinically anxious and 30 non-anxious control children and young adolescents. Anxious children tended to show larger electrodermal responses during habituation, but did not differ in blink startle latency or magnitude. After acquisition training, non-anxious children rated the CS+ as more fear provoking and arousing than the CS- whereas the ratings of anxious children did not differ. However, anxious children rated the CS+ as more fear provoking after extinction, a difference that was absent in non-anxious ...

    The habituation to intense acoustic stimuli and the acquisition of differentially conditioned fear were assessed in 53 clinically anxious and 30 non-anxious control children and young adolescents. Anxious children tended to show larger electrodermal responses during habituation, but did not differ in blink startle latency or magnitude. After acquisition training, non-anxious children rated the CS+ as more fear provoking and arousing than the CS- whereas the ratings of anxious children did not differ. However, anxious children rated the CS+ as more fear provoking after extinction, a difference that was absent in non-anxious children. During extinction training, anxious children displayed larger blink magnitude facilitation during CS+ and a trend towards larger electrodermal responses, a tendency not seen in non-anxious children. These data suggest that extinction of fear learning is retarded in anxious children.
