The influence of test-trial delay of CS onset in obtaining response summation of an excitatory CS and an independently conditioned context was investigated. Water-deprived rats were given tone-shock and click-shock pairings in the training context and unsignaled footshocks in the test context. Durations of lick suppression in response to the tone (Test 1) and the click (Test 2) were then assessed in the test context. Licking was more suppressed when CS onset occurred early in the test session (e.g., 0 sec) than when it occurred later in the test session (e.g., 300 sec). The results from control groups that had received shock in an irrelevant context rather than the test context indicated that this effect was due to fear of the test context rather than diffuse, nonassociative fear. With onset of the clicks early in the test session on the second test day, response summation of the test context with the clicks was observed. This suggests that appreciable spontaneous recovery had occurred from any test-context extinction that took place on the first test day. We conclude that early onset of the CS on the test trial favors response summation of CSs and test context. 相似文献

In the present experiment, we compared directly pigeons’ short-term memory of temporal and visual stimuli in a delayed matching-to-sample task. The sample stimuli consisted of red and green lights presented for 5 and 30 sec, followed by a retention interval and blue and yellow comparisons. For subjects in the visual group, duration was irrelevant and the color of the sample was the conditional cue. For animals in the temporal group, color was irrelevant and duration of the sample was the conditional stimulus. The results showed that acquisition of the matching task was faster and accuracy was higher in the visual than in the temporal group. More importantly, memory of either sample generally declined at a similar rate when the duration of the retention interval was increased and when the intertrial interval was reduced. Taken together, the results indicate that with 1–8-sec retention intervals, short-term memory for temporal stimuli is similar to that found with color-visual samples. The findings are discussed in terms of retrospective and prospective processing. 相似文献

Stimulated by special educational needs co-ordinators' (SENCos) reactions to a published image, the researchers used photovoice methodology to explore SENCos' images of themselves in relation to the perceptions of three groups of their colleagues: senior management team, teachers and teaching assistants. The analysis of the images involved the application of Activity Theory, which has the capacity to illuminate and explore the social context.
The results demonstrate the complexity of the role of the SENCo and the need to negotiate different perceptions. The authors argue the case for policies and procedure to fully take into account these differences. The adoption of this methodology helped to provide a deeper understanding of these issues. 相似文献
