(A) The latency to criterion is significantly longer in SRS + KA + normothermia group compared with the SA group by the second trial. The latency to criterion is significantly shorter in SRS + KA + hypothermia group compared with SRS + KA + normothermia group by fifth trial, but still longer compared with SA group by fourth trial. (B) More reference errors were found in the SRS + KA + normothermia group compared with the SA group by the third trial. More reference errors were found in the SRS + KA + hypothermia group compared with the SA group by the fourth trial. Fewer reference errors were found in the SRS + KA + hypothermia group compared with the SRS + KA + normothermia group by the fourth trial. (C) More working memory errors were found in the SRS + KA + normothermia group compared with the SA group at all trials. No significant difference in working memory errors was found between the SRS + KA + hypothermia group and the SA group. But fewer working memory errors were found in the SRS + KA + hypothermia group compared with the SRS + KA + normothermia group by the fourth trial. (D) More total entries were found in the SRS + KA + normothermia group compared with the SA group by the fourth trial. More total entries were found in the SRS + KA + hypothermia group compared with the SA group by the fifth trial. But fewer total entries were found in the SRS + KA + hypothermia group compared with the SRS + KA + normothermia group by the fourth trial, different than SA group, **P < 0.01, *P < 0.05; different than SRS + KA + normothermia groups, ∧
