Much research on cognitive development focuses either on early-emerging domain-specific knowledge or domain-general learning mechanisms. However, little research examines how these sources of knowledge interact. Previous research suggests that young infants can make inferences from samples to populations (Xu & Garcia, 2008) and 11- to 12.5-month-old infants can integrate psychological and physical knowledge in probabilistic reasoning (Teglas, Girotto, Gonzalez, & Bonatti, 2007; Xu & Denison, 2009). Here, we ask whether infants can integrate a physical constraint of immobility into a statistical (...) inference mechanism. Results from three experiments suggest that, first, infants were able to use domain-specific knowledge to override statistical information, reasoning that sometimes a physical constraint is more informative than probabilistic information. Second, we provide the first evidence that infants are capable of applying domain-specific knowledge in probabilistic reasoning by using a physical constraint to exclude one set of objects while computing probabilities over the remaining sets.

Yarkoni highlights patterns of overgeneralization in psychology research. In this comment, we note that such challenges also pertain to applied psychological and organizational research and practice. We use two examples – cross-cultural generalizability and implicit bias training – to illustrate common practices of overgeneralization from narrow research samples to broader operational populations. We conclude with recommendations for research and practice.

Community informatics and Information and Communications Technology for Development research projects frequently focus on the appropriation of ICTs and the design of information systems to meet the needs of communities. Such projects typically involve a range of participants reflecting different cultures and depend for their success on the ability of the project to bridge differences. Using PROTIC, a 5-year collaborative project between Monash University, Oxfam Australia and Oxfam in Bangladesh as a case study, this paper reflects on the use of (...) a “mainstream” form of participatory action research as a tool capable of engaging in more sustainable projects by helping to identify and to take into account localised or context-specific social and cultural issues in the design of the information system itself, consequently improving the effectiveness and sustainability of the systems developed. The idea of emic understandings of culture have also been used to interpret the project and PAR as an intercultural exchange around developing a community-focussed sociotechnical project. (shrink)

Obtaining prospective written consent from women to participate in trials when they are experiencing an obstetric emergency is challenging. Alternative consent pathways, such as gaining verbal consent at enrolment followed, later, by obtaining written consent, have been advocated by some clinicians and bioethicists but have received little empirical attention. We explored women’s and staff views about the consent procedures used during the internal pilot of a trial, where the protocol permitted staff to gain verbal consent at recruitment. Interviews with staff (...) and participating women. Data were analysed thematically and interviews were cross-compared to identify differences and similarities in participants’ views about the consent procedures used. Women and some staff highlighted benefits to obtaining verbal consent at trial enrolment, including expediting recruitment and reducing the burden on those left exhausted by their births. However, most staff with direct responsibility for taking consent expressed extreme reluctance to proceed with enrolment until they had obtained written consent, despite being comfortable using verbal procedures in their clinical practice. To account for this resistance, staff drew a strong distinction between research and clinical care and suggested that a higher level of consent was needed when recruiting into trials. In doing so, staff emphasised the need to engage women in reflexive decision-making and highlighted the role that completing the consent form could play in enabling and evidencing this process. While most staff cited their ethical responsibilities to women, they also voiced concerns that the absence of a signed consent form at recruitment could expose them to greater risk of litigation were an individual to experience a complication during the trial. Inexperience of recruiting into peripartum trials and limited availability of staff trained to take consent also reinforced preferences for obtaining written consent at recruitment. While alternative consent pathways have an important role to play in advancing emergency medicine research, and may be appreciated by potential recruits, they may give rise to unintended ethical and logistical challenges for staff. Staff would benefit from training and support to increase their confidence and willingness to recruit into trials using alternative consent pathways. This qualitative research was undertaken as part of the GOT-IT Trial. Date of registration 26/03/2014. (shrink)

This book brings together classic and recent papers in the philosophical and linguistic analysis of fuzzy grammar, gradience in meaning, word classes, and syntax. Issues such as how many grains make a heap, when a puddle becomes a pond, and so forth, have occupied thinkers since Aristotle and over the last two decades been the subject of increasing interest among linguists as well as in fields such as artificial intelligence and computational linguistics. The work is designed to be of use (...) to students in all these fields. It has a substantial introduction, is divided into thematic parts, contains annotated sections of further reading, and is fully indexed. (shrink)

The current investigation examines children’s learning about a novel machine in a local history museum. Parent–child dyads were audio-recorded as they navigated an exhibit that contained a novel artifact: a coffee grinder from the turn of the 20th century. Prior to entering the exhibit, children were randomly assigned to receive an experimental “component” prompt that focused their attention on the machine’s internal mechanisms or a control “history” prompt. First, we audio-recorded children and their caregivers while they freely explored the exhibit, (...) and then, we measured children’s learning by asking them two questions in a test phase. Children of all ages, regardless of the prompt given, discussed most aspects of the machine, including the whole machine, its parts, and, to a lesser extent, its mechanisms. In the test phase, older children recalled more information than younger children about all aspects of the machine and appeared more knowledgeable to adult coders. Overall, this suggests that children of all ages were motivated to discuss all aspects of a machine, but some scaffolding may be necessary to help the youngest children take full advantage of these learning opportunities. While the prompts did not significantly influence the number of children who discussed the machine’s mechanisms, children who received the component prompt were rated as more knowledgeable about the machine in the test phase, suggesting that this prompt influenced what they learned. Implications for visitor experience and exhibit design are discussed. (shrink)

While concerned with how man achieves his status as a moral being, Friedrich Schiller develops a concept of play that serves as a bridge between our sensuous existence to the rational, realizing moral freedom. In what ways might we extend this concept to the non-human animal? Current research by play theorists and ethologists has shown that play behaviour in animals is both complex and crucial in determining social patterns, and Schiller’s account may have anticipated these observations. I argue that through (...) Schiller’s theory of play and our current research on animal play, it is possible to undermine the systematic removal of the animal from the moral realm that happens in modern philosophy. Through play theory, there is a possible way to undermine the assumption that animals are incapable of achieving the status of moral agents, providing an alternate route to the standard view of animals as moral patients.
