This paper presents an implemented computational model of word acquisition which learns directly from raw multimodal sensory input. Set in an information theoretic framework, the model acquires a lexicon by finding and statistically modeling consistent cross‐modal structure. The model has been implemented in a system using novel speech processing, computer vision, and machine learning algorithms. In evaluations the model successfully performed speech segmentation, word discovery and visual categorization from spontaneous infant‐directed speech paired with video images of single objects. These results (...) demonstrate the possibility of using state‐of‐the‐art techniques from sensory pattern recognition and machine learning to implement cognitive models which can process raw sensor data without the need for human transcription or labeling.

This paper examines how the new field of neuroethics is responding to the old problem of difference, particularly to those ideas of biological difference emerging from neuroimaging research that purports to further delineate our understanding of sex and/or gender differences in the brain. As the field develops, it is important to ask what is new about neuroethics compared to bioethics in this regard, and whether the concept of difference is being problematized within broader contexts of power and representation. As a (...) feminist science studies scholar trained in the neurosciences, it seems logical to me that, as a growing field, neuroethics should reach out to the rich bodies of scholarship on the history of medicine, feminist theory and feminist bioethics while attempting to approach discussions of sex, gender and sexuality differences in the brain. What is also clear to me is that feminist scholars need to learn how to engage with neuroimaging studies on sex, gender and sexuality not just to critique, but also to productively contribute to neuroscientific research. The field of neuroethics can potentially provide the appropriate forum for this interdisciplinary engagement and create opportunities for shared perplexity. I suggest three possible points of departure for creating this shared perplexity, namely (i) is difference being measured in the study for the purpose of understanding difference in and of itself, or for the purpose of division?; (ii) is there an appreciation for biological complexity?; and (iii) is it assumed that structural differences can be conveniently translated into functional differences?

Although a rich tradition of feminist critiques of science exists, it is often difficult for feminists who are scientists to bridge these critiques with practical transformations in scientific knowledge production. In this paper, I go beyond the general bases of feminist critiques of science by using feminist theory in science to illustrate how a practical transformation in methodology can change molecular biology based research in the reproductive sciences.

We introduce a computational theory of situated language understanding in which the meaning of words and utterances depends on the physical environment and the goals and plans of communication partners. According to the theory, concepts that ground linguistic meaning are neither internal nor external to language users, but instead span the objective‐subjective boundary. To model the possible interactions between subject and object, the theory relies on the notion of perceived affordances: structured units of interaction that can be used for prediction (...) at multiple levels of abstraction. Language understanding is treated as a process of filtering perceived affordances. The theory accounts for many aspects of the situated nature of human language use and provides a unified solution to a number of demands on any theory of language understanding including conceptual combination, prototypicality effects, and the generative nature of lexical items.To support the theory, we describe an implemented system that understands verbal commands situated in a virtual gaming environment. The implementation uses probabilistic hierarchical plan recognition to generate perceived affordances. The system has been evaluated on its ability to correctly interpret free‐form spontaneous verbal commands recorded from unrehearsed game play between human players. The system is able to “step into the shoes” of human players and correctly respond to a broad range of verbal commands in which linguistic meaning depends on social and physical context. We quantitatively compare the system's predictions in response to direct player commands with the actions taken by human players and show generalization to unseen data across a range of situations and verbal constructions.

In this paper, Roy attempts to develop a semiprescriptive analysis for the natural sciences by examining more closely a skill that many feminist scientists have been reported to possess. Feminist scientists have often been lauded for their ability to “ask different questions.” Drawing from standpoint theory, strong objectivity, situated knowledges, agential realism, and the methodology of the oppressed, the author suggests that this skill can be articulated further into the feminist practice of research agenda choice. Roy illustrates the usefulness of (...) developing such a practice by addressing her own dilemma of conducting in vitro research in a reproductive biology lab. (shrink)

Intellectual humility, which entails openness to other views and a willingness to listen and engage with them, is crucial for facilitating civil dialogue and progress in debate between opposing sides. In the present research, we tested whether intellectual humility can be reliably detected in discourse and experimentally increased by a prior self-affirmation task. Three-hundred and three participants took part in 116 audio and video-recorded group discussions. Blind to condition, linguists coded participants’ discourse to create an intellectual humility score. As expected, (...) the self-affirmation task increased the coded intellectual humility, as well as participants’ self-rated prosocial affect (e.g., empathy). Unexpectedly, the effect on prosocial affect did not mediate the link between experimental condition and intellectual humility in debate. Self-reported intellectual humility and other personality variables were uncorrelated with expert-coded intellectual humility. Implications of these findings for understanding the social psychological mechanisms underpinning intellectual humility are considered. (shrink)
