WebbThe delay function at 5 months of age appears much sharper than is observed in adults, Together with the findings of A. H. Little et al (1984), the present study suggests a downward shift in the optimal delay interval for associative eyeblink conditioning between 1 and 6 months of age. WebbThe defining difference between delay and trace classical conditioning is simple: in delay conditioning, the unconditioned stimulus (US) immediately follows or coterminates with the conditioned stimulus (CS), whereas in trace conditioning, the CS and US are separated in time by a “trace” interval.

Webbbecome associated).In eyeblink conditioning in animals, a typi-cal trace interval is 500 msec.The trace CR is more difficult to learn than the standard “delay” procedure where the CS and US overlap in time. Simply comparing standard delay conditioning with trace conditioning can confound CS–US onset interval: In the delay WebbAWARENESS AND FEAR CONDITIONING 159.05]. During delay conditioning, CS presentations were perceived at a lower threshold than during the trace proce-dure [t(12) 2.39, p .05].
