Across three experiments, we examined 9‐ and 11‐month‐olds' mappings of novel sound properties to novel animal categories. Infants were familiarized with novel animal–novel sound pairings (e.g., Animal A [red]–Sound 1) and then tested on: (1) their acquisition of the original pairing and (2) their generalization of the sound property to a new member of a familiarized category (e.g., Animal A [blue]–Sound 1). When familiarized with a single exemplar of a category, 11‐month‐olds showed no evidence of acquiring or generalizing the animal–sound pairings. In contrast, 11‐month‐olds learnt the original animal–sound mappings and generalized the sound property to a novel member of that category when familiarized with multiple exemplars of a category. Finally, when familiarized with multiple exemplars, 9‐month‐old infants learnt the original animal–sound pairing, but did not extend the novel sound property. The results of these experiments provide evidence for developmental differences in the facilitative role of multiple exemplars in promoting the learning and generalization of information. 相似文献
Objectives: The current study evaluated women's salivary testosterone and estradiol levels before and after exposure to sexual stimuli in a U.S. sex club. Methods: Behavioral data and salivary samples were collected from 19 women during semistructured interviews. Results: Findings demonstrate substantial individual differences in the magnitude and direction of women's hormonal changes following sexual activity. Conclusions: In an age of individualized medicine, these findings highlight the need to better understand factors shaping variation in physiological responses to sexual activity. Findings contribute to a relatively small and contradictory literature on women's hormonal responses to sexual stimuli. 相似文献
An increasing challenge for teaching methods courses in the social sciences is the ‘critical turn’, which has encouraged some students to adopt an anti-empirical orientation. We present a case study of a compulsory undergraduate methods course in a political science department strongly influenced by post-structuralist philosophies. The first author redesigned the course to implement four constructivist pedagogical principles: (1) develop a full understanding of students’ pre-existing perceptions of political science research methods; (2) encourage students to see methodology as an inevitably contested field; (3) provide space for students to choose a methodological approach that best aligns with their personal stance on knowledge; and (4) encourage students to view research as an ongoing ‘conversation’. We critically reflect on the implementation of these constructivist pedagogical strategies and argue they improve students’ critical engagement with course material, increase linkages between methods teaching and other disciplinary subject matter, and accommodate diverse student perspectives and needs. 相似文献
Sustainable landscaping programs are voluntary initiatives that recommend a set of practices to improve the environmental quality of urban ecosystems by providing landscaping materials, guidelines, and educational resources. Our goal was to examine the recommendations and outcomes of these programs in the United States and their value for encouraging conservation practices in residential ecosystems. We conducted a comprehensive web search and identified 193 sustainable landscaping programs in the United States. Programs aim to increase native species richness, affordably manage stormwater runoff, and offer residents meaningful experiences with nature. Sustainable landscaping programs present many opportunities to engage people with local ecological knowledge and conservation practices, provide accessible spaces for environmental education, cultivate interdisciplinary research collaborations, and advance inclusion in conservation. However, assessments of their ecological value are rare, leaving many questions surrounding the benefits to biodiversity and water quality afforded by participation. Many programs also require investments in landscaping materials and certification fees that might limit participation by some households. Future work should examine how recommended practices influence urban biodiversity, identify and address barriers to participation, and generate social-ecological knowledge that can inform future programs.
Infants in laboratory settings look longer at events that violate their expectations, learn better about objects that behave unexpectedly, and match utterances to the objects that likely elicited them. The paradigms revealing these behaviors have become cornerstones of research on preverbal cognition. However, little is known about whether these canonical behaviors are observed outside laboratory settings. Here, we describe a series of online protocols that replicate classic laboratory findings, detailing our methods throughout. In Experiment 1a, 15-month-old infants (N = 24) looked longer at an online support event culminating in an Unexpected outcome (i.e., appearing to defy gravity) than an Expected outcome. Infants did not, however, show the same success with an online solidity event. In Experiment 1b, 15-month-old infants (N = 24) showed surprise-induced learning following online events—they were better able to learn a novel object's label when the object had behaved unexpectedly compared to when it behaved expectedly. Finally, in Experiment 2, 16-month-old infants (N = 20) who heard a valenced utterance (“Yum!”) showed preferential looking to the object most likely to have generated that utterance. Together, these results suggest that, with some adjustments, online testing is a feasible and promising approach for infant cognition research. 相似文献
Recognizing the intent of Affirmative Action to include historically marginalized citizens into institutions of higher learning, we stretch the limits of Affirmative Action to consider the role of higher education in prison. We present empirical findings of a 4-year, qualitative and quantitative participatory action research study of the impact of college in prison. Evidence is drawn from participant observations; individual and focus group interviews with participants of the college program, former inmates, prison administrators, corrections officers, and children of inmates; faculty surveys; and a quantitative analysis of recidivism rates. We address the psychological, academic, and crime-related impacts of higher education on women in prison, and document the benefits of broad-based access for inmates, prison environments, children of prisoners, and society-at-large. 相似文献
It is popularly believed that justifying an affirmative action plan (AAP) through emphasizing the advantages that diverse students can bring to a college campus will increase nonbeneficiary support for the program. However, there has been little empirical support for this proposition, perhaps because previous research has not directly articulated to participants the value of a diverse student body. As such, the current study sought to determine how the explicit framing of an AAP influences subsequent reactions. Both quantitative and qualitative data from 216 White undergraduate participants revealed that the utilitarianism justification that highlighted the benefits of the AAP to both minority and majority students, was the most effective means of increasing support for the plan. 相似文献
The formal rules, structure and practice of most sports in contemporary society prohibit men and women from competing on a ??level playing field?? and diminish women??s ability to launch a legitimate challenge to the masculine superiority embedded in sports competition. This study examines a relatively unique case??No Limit Texas Hold Em poker games in which men and women compete directly against one another under the same rules??to explore how the conditions under which men and women compete enable or impede the development of more gender egalitarian interactions and ideological frameworks. Drawing on ethnographic data, this examination reveals that, even in a more gender-neutral context, men and women learn to use heterogender frames to conceptualize poker. In doing so, they develop competitive strategies and interactions that predominately fit into, rather than subvert, gender hierarchy. 相似文献
The following article provides a snapshot of the current self‐direction movement within the disability sector across the industrialised world, with particular emphasis on the Australian context. As a global movement, self‐direction has been in progress for several decades through a variety of implemented responses. Despite implementation variation, all self‐direction models aim to facilitate individual control and decision making in care and support services. We describe self‐direction, its various models and programs, and explore its benefits and challenges. We conclude by making broad recommendations for decision makers involved in self‐direction. In particular, we offer a hierarchical decision tree that can be used to inform policy decisions at a systems – government policy – and organisational level. 相似文献
AbstractObjective: The purpose of this study was to determine the utility and unique benefits of employing the College Health Questionnaire (CHQ) in a college health care setting. The CHQ is a newly designed measure to assess psychosocial issues commonly problematic among college students. Participants: One hundred nine patients participated in the study during their medical appointments. Methods: Participants completed the study questionnaires (CHQ and Patient Health Questionnaire) in the waiting room. Their provider had the opportunity to use the responses in treatment decision making. Results: A majority (66.1%) endorsed at least one CHQ item. Patients who indicated traditional mental health problems were more likely to be prescribed psychotropic medications, whereas patients who endorsed psychosocial issues commonly problematic among college students were more likely to be referred for behavioral treatment. Conclusions: Screening for behavioral problems in college primary care settings without the use of college-related questions would result in missing numerous important psychosocial problems. 相似文献
