文摘

Fast specific fear learning occurs when a single conditioning experience produces situation-specific fear. Fast specific fear learning emerged in verbal ratings, skin conductance, and fear-potentiated startle. Fast specific fear learning correlated marginally significantly with trait and state anxiety. Fast specific fear learning is more consistent with configural compared to elemental models of associative learning. Failures in fast specific fear learning may result in overgeneralization.
