The present study investigated context effects of incidental odors in free recall after a short retention interval (5 min). With a short retention interval, the results are not confounded by extraneous odors or encounters with the experimental odor and possible rehearsal during a long retention interval. A short study time condition (4 s per item), predicted not to be affected by adaptation to the odor, and a long study time condition (8 s per item) were used. Additionally, we introduced a new method for recovery from adaptation, where a dissimilar odor was briefly presented at the beginning of the retention interval, and we demonstrated the effectiveness of this technique. An incidental learning paradigm was used to prevent overshadowing from confounding the results. In three experiments, undergraduates (N = 200) incidentally studied words presented one-by-one and received a free recall test. Two pairs of odors and a third odor having different semantic-differential characteristics were selected from 14 familiar odors. One of the odors was presented during encoding, and during the test, the same odor (same-context condition) or the other odor within the pair (different-context condition) was presented. Without using a recovery-from-adaptation method, a significant odor-context effect appeared in the 4-s/item condition, but not in the 8-s/item condition. Using the recovery-from-adaptation method, context effects were found for both the 8- and the 4-s/item conditions. The size of the recovered odor-context effect did not change with study time. There were no serial position effects. Implications of the present findings are discussed. 相似文献

We investigated whether postpartum anxiety (PPA) and breastfeeding self-efficacy and bonding at the early postpartum period can be used to predict postpartum depression and the breastfeeding method, and we sought to identify factors related to postpartum depression. Of the 510 eligible women, 185 (36%) returned the questionnaire on all three occasions (1 day, 3 days, and 1 month after childbirth). The mothers' progress on the State-Trait Anxiety Inventory (STAI), Breastfeeding Self-Efficacy Scale Short Form (BFSES-SF), and Postnatal Bonding Questionnaire (PBQ) was observed over three periods. A repeated-measures ANOVA revealed that the mothers at high risk of developing postpartum depression (PPD) were those who did not show an increase in BFSES-SF score at early postpartum, and mothers whose bonding disorders have deteriorated rapidly. The results of the logistic regression analysis revealed a significant difference in employment as a factor related to postpartum depression. Compared to Regular, Part-time status was 4.4 times more likely and Unemployed status was 2.3 times more likely to cause postpartum depression. For the early detection of PPD, it is necessary to identify (1) mothers who do not show an increase in the BFSES-SF score, (2) mothers whose bonding disorders have deteriorated rapidly, and (3) part-time or unemployed mothers as characteristic of postpartum depression. 相似文献

This study aimed to examine the characteristics of families’ behavioral repertoires in hikikomori (prolonged social withdrawal) cases. We asked 243 parents of individuals with hikikomori (hikikomori group) to complete the Family Behavioral Repertoire Scale for Coping With Hikikomori (FBS-H), the Negative Evaluation of Hikikomori Scale, and a self-efficacy measure of coping with problem behaviors of hikikomori in order to develop the FBS-H and to examine its reliability and validity. Additionally, we examined the characteristics of hikikomori cases regarding the families’ behavioral repertoires using data from the hikikomori group and from 458 parents of individuals with no experience of hikikomori (control group). The results of the analysis indicated the acceptable reliability and validity of the FBS-H. The hikikomori group did not have lower FBS-H scores than the control group. This result indicates the possibility that a family's behavioral repertoire does not strongly influence the “expression” of hikikomori. Further research is needed to clarify the influence of families’ behavioral repertoires to refine family support. 相似文献
