“…This observation of more freezing to tone than to light is consistent with other recent reports (Ayres et al, 1985;Sigmundi & Bolles, 1983), and it does not appear to be dependent upon some peculiarity of our tone and light CS. Modality differences in the ratio of freezing to "other" defensive behaviors could be partly responsible for the differences in judgments of conditioning to tone and light CSs, judgments based on the difference in lick suppression evoked by CS + versus CS -.…”

“…For the tone CS +, the suppression of nosing was well accounted for by large increases in freezing and smaller increases in "other" behavior; for the light CS +, the suppression of nosing was well accounted for in terms oflarge increases in "other" behavior and small increases in freezing. This pattern of results is entirely consistent with Sigmundi and Bolles's (1983) suggestion that rats engage in different defensive behaviors to stimuli in different modalities. Freezing appears to be the dominant defensive behavior evoked by auditory CS+s, and "other" appears to be the dominant defensive behavior evoked by visual CS+s.…”

“…Unfortunately, from Sigmundi and Bolles (1983), Ayres et al (1985), and the present experiment, we do not gain a clear picture of what the "other" defensive behaviors are. We can only say that, in contrast to the suggestion of Ayres et al (1985), they do not seem to include rearing.…”

“…The second aim of Experiment 4 was to see what the rats were actually doing during the tone and light ess. Sigmundi and Bolles (1983), using a time-sampling technique, directly observed the freezing behavior of rats in the presence and absence of CSs that had been repeatedly paired with shock. They found that rats froze much more to a white-noise es than to a light.…”

Rats received a single 4-sec I-rnA grid-shock US either preceded or followed by a 4-sec tone or light CS. Conditioning was later assessed by comparing the amount oflick suppression evoked by the forward-or backward-paired CS versus an explicitly unpaired CS. The backward-paired CS produced more suppression than the unpaired CS only when both were tone; the light evoked . strong suppression whether paired or not. In the forward procedure, tone produced more suppression when paired and less when unpaired than did light; conditioning thus appeared stronger with the tone. In one experiment, observations showed that rats froze during the forward-paired tone but not during the light. Increasing CS duration from 4 to 12 sec had no effect for the forwardpaired light but increased freezing to the forward-paired tone. Another experiment showed similar unconditioned suppression to tone and light but faster habituation to tone. Problems that these results create for interpreting evidence for excitatory backward conditioning in the conditioned suppression procedure are discussed.

“…Balsam and Gibbon employed an autoshaping procedure with pigeons, whereas Williams et al used rats as subjects, a shock as a US, and freezing, a species-specific defence reaction, as a measure of context conditioning (see also, e.g., Sigmundi & Bolles, 1983).…”

The Effect of a Discrete Signal on Context Conditioning: Assessment by Preference and Freezing Tests

Four experiments with rats assessed conditioning to contextual cues after the delivery of footshocks that were either signaled by a discrete stimulus or unsignaled. Two different tests were used. The first was a context preference test in which subjects were allowed to move freely in a brightly lit, unconditionally aversive context and the former shock context. The second test consisted of scoring freezing behavior while the animals were confined to the former conditioning context. During context preference tests, signaled-shock animals spent more time in the conditioning context and/or entered that context more frequently than did unsignaled-shock subjects. However, freezing tests largely failed to detect a difference between groups. These results were discussed in terms of possible interactions between the formation of contextshock, signal-shock, and context-signal associations and their effect on performance in each of the two types of tests. ᭧
