While social learning has been demonstrated in species across many taxa, the role it plays in everyday foraging decisions is not well understood. Investigating social learning during foraging could shed light on the emergence of cultural variation in different groups. We used an open diffusion experiment to examine the spread of a novel foraging technique in captive Amazon parrots. Three groups were tested using a two-action foraging box, including experimental groups exposed to demonstrators using different techniques and control birds. We also examined the influence of agonistic and pilfering behaviour on task acquisition. We found evidence of social learning: more experimental birds than control birds interacted with and opened the box. The birds were, however, no more likely to use the demonstrated technique than the non-demonstrated one, making local or stimulus enhancement the most likely mechanism. Exhibiting aggression was positively correlated with box opening, whilst receiving aggression did not reduce motivation to engage with the box, indicating that willingness to defend access to the box was important in task acquisition. Pilfering food and success in opening the box were also positively correlated; however, having food pilfered did not affect victims’ motivation to interact with the box. In a group context, pilfering may promote learning of new foraging opportunities. Although previous studies have demonstrated that psittacines are capable of imitation, in this naturalistic set-up there was no evidence that parrots copied the demonstrated opening technique. Foraging behaviour in wild populations of Amazons could therefore be facilitated by low-fidelity social learning mechanisms.  相似文献

We conducted an exploratory, qualitative study investigating experiences of women who had developed breast cancer under the age of 40 and who were identified as BRCA1 or BRCA2 mutation carriers. These germline mutation carriers face an increased lifetime risk of a second primary breast cancer and an increased risk for a primary ovarian cancer. Thirteen women who fit this criteria participated in three focus groups conducted at a major cancer center in the UK during Spring 2003. We asked broad, open-ended questions that allowed for a wide range of responses about their cancer and genetic testing experiences, physical and psycho-social concerns, family and partner reactions and their need for social support. The women expressed feelings of devastation, loneliness, feeling different and isolation, ambivalence about having to support family members, worries about partner’s anxiety and depression, and anxiety about talking to family members, especially children. These feelings were stronger after the cancer diagnosis and compounded by the genetic test results that occurred at a later time. We also found that, at least temporarily, the women experienced what we call “social separation”—emotional distance from, or dissonance with groups they interact with or are part of, e.g., family and friends, frequently leading to a reduction in communication or a change in previously unstated, but accepted normal interaction. We concentrate on a few characteristics of social separation—feelings of aloneness, isolation and separation, use of silence and verbal discretion, the relationship between estrangement and kinship interaction and norm disruption, and are looking at social patterns of interpersonal relationships that may occur when risk and illness statuses are new and framing and feeling rules have not as yet been clearly developed due to a cultural lag.  相似文献

Absorbing the immigrants from the Middle East and North Africa in Israel was one of the Israeli education system’s important tasks. This article deals with the way the National Religious schools treated these new immigrants and their descendants, known as Oriental Jews, Mizrahi Jews, or “Mizrahim.” The differences between Mizrahi Jews and Ashkenazi Jews (those of European ancestry) were related to differences in religious traditions, academic level, and religious observance. Educators imposed the Ashkenazi tradition on Mizrahi pupils. This created social tension and alienated Mizrahi pupils from the system. On the other side, Ashkenazi pupils who had difficulties with the heterogeneous educational environment left the public system and enrolled in more religious schools, which had a much smaller percentage of Mizrahi pupils. This segregation was even more common at the high school level. Ashkenazim attended yeshiva high schools, while Mizrahi pupils went to regular high schools. Small changes were evident by the 1990s. By that time, more Mizrahi pupils were attending the elite yeshivot, and the public system adopted a more multicultural attitude and included the Mizrahi tradition as well.  相似文献

Prenatal mental illness is a significant public health issue with intergenerational consequences. Caring for Body and Mind in Pregnancy (CBMP) is an Australian, 8-week mindful parenting program. The primary aim of this study was to investigate the effectiveness of CBMP in reducing pregnant women’s levels of depression, anxiety, perinatal depression, perinatal anxiety and stress. The sample consisted of 109 pregnant women at-risk for perinatal depression and anxiety. The mean age of the sample was 33.52 years (SD?=?4.90), ranging from 21 to 45 years. A within group, pre-post research design was used to examine whether CBMP improves participants’ scores on outcome measures. Wilcoxon Signed Rank test results indicated that CBMP significantly reduced depression, anxiety, perinatal depression, perinatal anxiety and general stress scores, while significantly increasing self-compassion and mindfulness with moderate to strong effect sizes. The double mediation hypothesis was supported with self-compassion t (71)?=??2.23, p?<?03, b2?=??1.96, SE?=?88, 95% CI?=??3.71, ?.20, having a stronger influence in reducing perinatal depression than mindfulness t (71)?=??2.68, p?<?.01, b3?=??.07, SE?=?.03, 95% CI?=??.13, ?.02. Further research, using a randomized controlled design with appropriate control conditions, is needed to establish the effectiveness of CBMP in reducing psychological distress amongst pregnant women at risk of developing depression, anxiety or stress.  相似文献

From an anecdotal rumination, the authors make the case for consideration of past reflections, in what they call 'composting', to inspire and enrich new, different and currently ongoing reflective activity and initiatives.  相似文献

This study investigates the relationship of women's current role choices, role satisfaction, and self-esteem to their perceptions of the earlier relationship with their mothers and to their perceptions of their mothers' role choices and role satisfaction. Sixty-seven married women with preschool children were interviewed and completed self-report inventories. Results indicated that the women's primary role decisions of career, non-career work, or homemaking did not parallel those of their mothers but was related to their mothers' messages to them. In addition, career women and women at home reported having more choice in their decisions than did non-career working women. Women's self-esteem and role satisfaction were significantly enhanced ( p <.05) when the relationship with the mother was perceived as loving and accepting, with low hostility and low psychological control. In contrast, women's self-esteem and role satisfaction were generally unrelated to the retrospective reports of the mothers' roles and role satisfaction.  相似文献

The relation of well-being to involvement in multiple roles was examined in a study of 134 Caucasian women. All subjects were married and mothers of at least one preschool child; 50 were also paid workers. Two indices of well-being were used: (a) self-esteem; and (b) satisfaction with one's current role pattern. No differences in level of well-being were found between the employed and nonemployed groups. Findings were discussed in relation to theoretical perspectives on multiple role involvement.  相似文献
