Agnosticism gone awry: Why developmental robotics must commit to an understanding of embodiment and shared intentionality

We argue that developmental robotics, in its integration of developmental psychology and robotics, has the potential to encounter unexpected and unexamined conceptual difficulties. In particular, the various uses of embodiment and shared intentionality single out certain robots and behaviors as more or less relevant for the modeling of social cognition. As these terms have relatively orthogonal histories, there is no account for how their use will interact to shape methodology. We provide a brief discussion of how they may do so. Moreover, theorists often avoid explicit endorsement of some use or another. Although this agnosticism is understandable, we use the model of Dominey and Warneken (2011) as an illustrative example of why it is potentially dangerous. While Dominey and Warneken have succeeded in encouraging theorists to adopt clearer formulations of shared intentionality, their model suffers from important difficulties in interpretation, which, we argue, are a consequence of their uses of embodiment and shared intentionality respectively.

Individual and Group Meaning: Exploring the Reciprocal Relation

Abstract

Group construct systems were defined through application of a group construct grid that elicited types of groups in which an individual had participated or closely observed. The Group Grid was administered at the beginning and the end of a 4-month graduate class. The meanings of groups to participants were interpreted by examining changes in Group Grids over time and in relation to high and low levels of group performance. The meaning of individuals to the group was assessed by peer evaluations given at the end of the project. High and low levels of peer evaluation were then predicted by an individual's Group Grid measures. The most consistent findings were that greater variation in application regarding types of groups and characteristics about groups showed strong associations with both high levels of group performance and high levels of peer evaluation. Suggestions are given for future research     

Remarks on counterpossibles

Since the publication of David Lewis’ Counterfactuals, the standard line on subjunctive conditionals with impossible antecedents (or counterpossibles) has been that they are vacuously true. That is, a conditional of the form ‘If p were the case, q would be the case’ is trivially true whenever the antecedent, p, is impossible. The primary justification is that Lewis’ semantics best approximates the English subjunctive conditional, and that a vacuous treatment of counterpossibles is a consequence of that very elegant theory. Another justification derives from the classical lore than if an impossibility were true, then anything goes. In this paper we defend non-vacuism, the view that counterpossibles are sometimes non-vacuously true and sometimes non-vacuously false. We do so while retaining a Lewisian semantics, which is to say, the approach we favor does not require us to abandon classical logic or a similarity semantics. It does however require us to countenance impossible worlds. An impossible worlds treatment of counterpossibles is suggested (but not defended) by Lewis (Counterfactuals. Blackwell, Oxford, 1973), and developed by Nolan (Notre Dame J Formal Logic 38:325–527, 1997), Kment (Mind 115:261–310, 2006a: Philos Perspect 20:237–302, 2006b), and Vander Laan (In: Jackson F, Priest G (eds) Lewisian themes. Oxford University Press, Oxford, 2004). We follow this tradition, and develop an account of comparative similarity for impossible worlds.     

Negotiating religion in everyday life: A critical exploration of the relationship between religion,choices and behaviour

One of the characteristics most often associated with religion is that it is a discrete source of value that shapes people's attitudes and behaviour. In some cases, these values may be negative such as submission or violence; in other cases, religion is seen to promote positive values such as charity and social justice. In recent years, the international development community has reawakened an interest in religion, and has directly embraced the assumption that religion is foundational of people's values, seeking how best to tap into the potential positive values while mitigating against the more negative values. This paper critically explores the assumptions behind this approach. It argues that there is no straightforward relationship between belonging to a religion and the values which inform one's actions and decisions. Drawing on fieldwork research from India, the paper shows that it is impossible to disentangle religion from its interaction with the social, economic and political contexts in which it is lived. The paper concludes by deriving some implications of this for the way the international development community engages with religion.     

A Seat at the Table: Using Social Media as a Platform to Resolve Microaggressions Against Transgender Persons

Transgender, gender variant, and/or gender nonconforming persons are marginalized and pathologized in society and communities. The advent and widespread use of social media introduce an entirely new avenue of expression where cyber bullying and verbal assaults are common. Yet, social media also has the capacity to reach more people in more places, thus presenting a potentially powerful platform for advocacy. Grounded in digital critical participatory action research, the authors present a multimedia advocacy project that highlights advocacy strategies in which counselors can utilize social media to raise awareness, promote inclusion, and resolve microaggressions toward transgender persons.     

Conditioned taste aversions: From poisons to pain to drugs of abuse

Learning what to eat and what not to eat is fundamental to our well-being, quality of life, and survival. In particular, the acquisition of conditioned taste aversions (CTAs) protects all animals (including humans) against ingesting foods that contain poisons or toxins. Counterintuitively, CTAs can also develop in situations in which we know with absolute certainty that the food did not cause the subsequent aversive systemic effect. Recent nonhuman animal research, analyzing palatability shifts, has indicated that a wider range of stimuli than has been traditionally acknowledged can induce CTAs. This article integrates these new findings with a reappraisal of some known characteristics of CTA and presents a novel conceptual analysis that is broader and more comprehensive than previous accounts of CTA learning.     

Phonological Concept Learning

Linguistic and non‐linguistic pattern learning have been studied separately, but we argue for a comparative approach. Analogous inductive problems arise in phonological and visual pattern learning. Evidence from three experiments shows that human learners can solve them in analogous ways, and that human performance in both cases can be captured by the same models. We test GMECCS (Gradual Maximum Entropy with a Conjunctive Constraint Schema), an implementation of the Configural Cue Model (Gluck & Bower, 1988a ) in a Maximum Entropy phonotactic‐learning framework (Goldwater & Johnson, 2003 ; Hayes & Wilson, 2008 ) with a single free parameter, against the alternative hypothesis that learners seek featurally simple algebraic rules (“rule‐seeking”). We study the full typology of patterns introduced by Shepard, Hovland, and Jenkins ( 1961 ) (“SHJ”), instantiated as both phonotactic patterns and visual analogs, using unsupervised training. Unlike SHJ, Experiments 1 and 2 found that both phonotactic and visual patterns that depended on fewer features could be more difficult than those that depended on more features, as predicted by GMECCS but not by rule‐seeking. GMECCS also correctly predicted performance differences between stimulus subclasses within each pattern. A third experiment tried supervised training (which can facilitate rule‐seeking in visual learning) to elicit simple rule‐seeking phonotactic learning, but cue‐based behavior persisted. We conclude that similar cue‐based cognitive processes are available for phonological and visual concept learning, and hence that studying either kind of learning can lead to significant insights about the other.     

Just how controversial is evidential holism?

This paper is an examination of evidential holism, a prominent position in epistemology and the philosophy of science which claims that experiments only ever confirm or refute entire theories. The position is historically associated with W.V. Quine, and it is at once both popular and notorious, as well as being largely under-described. But even though there’s no univocal statement of what holism is or what it does, philosophers have nevertheless made substantial assumptions about its content and its truth. Moreover they have drawn controversial and important conclusions from these assumptions. In this paper I distinguish three types of evidential holism and argue that the most oft-cited and controversial thesis is entirely unmotivated. The other two theses are much overlooked, but are well-motivated and free from controversial implications.     

Vigilance and Avoidance of Threat in the Eye Movements of Children with Separation Anxiety Disorder

The vigilance-avoidance attention pattern is found in anxious adults, who initially gaze more at threatening pictures than nonanxious adults (vigilance), but subsequently gaze less at them than nonanxious adults (avoidance). The present research, using eye tracking methodology, tested whether anxious children show the same pattern. Children with separation anxiety disorder or no mental disorder viewed pairs of pictures, while the direction of their gaze was tracked. Each picture pair showed one picture of a woman separating from a child, the other picture of a woman reuniting with a child. The results supported the vigilance-avoidance model in children. Although the two groups’ gaze direction did not differ during the first second of viewing, anxious children gazed significantly more at separating (threatening) pictures than nonanxious children after a period of 1 s. But after 3 s the pattern reversed: anxious children gazed significantly less at the separating pictures than nonanxious children.
