Across two studies participants completed a learning phase comprised of two types of trials: context pairing trials in which two (valenced or non-valenced) words were identical or opposite to one another and evaluative conditioning (EC) trials in which a CS was paired with a US. Based on the idea that EC occurs because CS-US pairings function as a symbolic cue about the relation between the CS and the US, we hypothesised that the nature of context pairings (identical or opposite) might moderate EC effects. Results indicate that identity-based context pairs led to typical assimilative explicit and implicit effects whereas opposition-based pairs led to attenuated effects. Implications and different accounts of our findings are discussed. 相似文献

Vitamin E (α-tocopherol), a lipid-soluble anti-oxidant, prevents the uncontrolled propagation of lipid peroxidation by free radicals. Nevertheless, there is weak or no evidence of a protective effect of previous vitamin E intake on cognitive function in humans. In the present study, we explored the thermosensation model to investigate the possible effects of vitamin E administration on memory behaviors in Caenorhabditis elegans. Administration of 100 and 200 μg/mL of vitamin E had no significant effects on the memory for different time intervals, whereas relatively high concentration (400 μg/mL) of vitamin E exposure shortened the extinction period of the association paradigm (food at 20 °C). Following the UV-irradiation, post-treatment with 200 μg/mL of vitamin E not only retrieved the UV-irradiation-induced memory deficits, but also enhanced the memory functions in UV-irradiating animals. Post-treatment with trace vitamin E could also ameliorate the memory deficits in metal (Al or Pb) exposed worms. In addition, pre-treatment with 200 μg/mL of vitamin E could effectively prevent the occurrence of memory deficits induced by metal exposure and UV-irradiation. Therefore, the close association may exist between trace dietary vitamin E intake and memory behaviors, and a specific response mechanism may be activated after the administration of vitamin E in stress-exposed animals. Moreover, treatment with 200 μg/mL of vitamin E could restore the memory deficits formed in the ncs-1 mutant worms, suggesting that exogenous treatment with trace vitamin E can largely mimic the function of NCS-1 in regulating the memory for thermosensation. 相似文献
