The role of robotic modelling in cognitive science

From the perspective of cognitive robotics, this paper presents a modern interpretation of Newell’s (1973) reasoning and suggestions for why and how cognitive psychologists should develop models of cognitive phenomena. We argue that the shortcomings of current cognitive modelling approaches are due in significant part to a lack of exactly the kind of integration required for the development of embodied autonomous robotics. Moreover we suggest that considerations of embodiment, situatedness, and autonomy, intrinsic to cognitive robotics, provide an appropriate basis for the integration and theoretic cumulation that Newell argued was necessary for psychology to mature. From this perspective we analyse the role of embodiment and modes of situatedness in terms of integration, cognition, emotion, and autonomy. Four complementary perspectives on embodied and situated cognitive science are considered in terms of their potential to contribute to cognitive robotics, cognitive science, and psychological theorizing: minimal cognition and organization, enactive perception and sensorimotor contingency, homeostasis and emotion, and social embedding. In combination these perspectives provide a framework for cognitive robotics, not only wholly compatible with the original aims of cognitive modelling, but as a more appropriate methodology than those currently in common use within psychology.     

OPTIMAL practice conditions enhance the benefits of gradually increasing error opportunities on retention of a stepping sequence task

IntroductionPhysical therapists should implement practice conditions that promote motor skill learning after neurological injury. Errorful and errorless practice conditions are effective for different populations and tasks. Errorful learning provides opportunities for learners to make task-relevant choices. Enhancing learner autonomy through choice opportunities is a key component of the Optimizing Performance through Intrinsic Motivation and Attention for Learning (OPTIMAL) theory of motor learning. The objective of this study was to evaluate the interaction between error opportunity frequency and OPTIMAL (autonomy-supportive) practice conditions during stepping sequence acquisition in a virtual environment.MethodsForty healthy young adults were randomized to autonomy-supportive or autonomy-controlling practice conditions, which differed in instructional language, focus of attention (external vs internal) and positive versus negative nature of verbal and visual feedback. All participants practiced 40 trials of 4, six-step stepping sequences in a random order. Each of the 4 sequences offered different amounts of choice opportunities about the next step via visual cue presentation (4 choices; 1 choice; gradually increasing [1-2-3-4] choices, and gradually decreasing [4-3-2-1] choices). Motivation and engagement were measured by the Intrinsic Motivation Inventory (IMI) and the User Engagement Scale (UES). Participants returned 1–3 days later for retention tests, where learning was measured by time to complete each sequence. No choice cues were offered on retention.ResultsParticipants in the autonomy-supportive group outperformed the autonomy-controlling group at retention on all sequences (mean difference 2.88s, p < .005, t[6835] = 3.42). Participants in both groups had the most difficulty acquiring the decreasing choice (4-3-2-1) sequence (p < .001, t[6835] = −4.26) and performed most poorly on the errorful (4 choice) sequence (p < .034, t[6835] = 2.65) at retention. Participants in the autonomy-supportive group performed best at retention on the increasing choice (1-2-3-4) sequence (p < .033, t[6835] = −2.7). Participants in both groups who reported greater attention to the task on the UES Average Focused Attention subscale during acquisition had poorer retention performance, particularly for the decreasing choice (4-3-2-1) sequence (p < .005, t(6835) = 3.39). Participants in the autonomy-supportive group reported significantly higher overall motivation (p = .007, t(38) = 0.728, d = 0.248) on the IMI as compared to the autonomy-controlling group.ConclusionIndividual benefits of errorless learning and autonomy-supportive practice conditions, with an interaction effect for practice that begins errorless but adds increasing error opportunities over time, suggest that participants relied on implicit learning strategies for this full body task and that feedback about successes minimized errors and reduced their potential information-processing benefits. Subsequent work will continue to examine how assigning a positive versus a negative quality to error provision influences the benefits of errorful learning in a variety of tasks.

The Headscarf Controversy: A Response to Jill Marshall

This paper argues that Article 8 of the ECHR, as applied to the protection of a person’s right to wear a headscarf, is an inappropriate locus for thrashing out arguments about the right to protection of religious freedom, and that Article 9 allows for a broader legal and political analysis of the multiple meanings and impacts of religion in our lives. However, the law should not prohibit women from wearing the headscarf. Legal regulation of the headscarf should be replaced with robust political debate about the many diverse and intersecting ways in which it is possible to experience womanhood, sexuality, culture, religion, race, nationality and economic security in the twenty-first century.

Reply to Wilkinson

In his review of my book Whose Body is It Anyway, Wilkinson criticises the view (which I defend) that confiscating live body parts for the sake of the needy is (under some circumstances) a requirement of justice. Wilkinson makes the following three points: (a) the confiscation thesis is problematic on its own terms; (b) there is a way to justify coercive resource transfers without being committed to it; (c) the thesis rests on a highly questionable approach to the status of the body. Wilkinson’s paper is challenging, and some of his points are well taken. On the whole, however, it does not constitute an insurmountable challenge for my thesis.

Biobank research and the right to privacy

What is privacy? What does privacy mean in relation to biobanking, in what way do the participants have an interest in privacy, (why) is there a right to privacy, and how should the privacy issue be regulated when it comes to biobank research? A relational view of privacy is argued for in this article, which takes as its basis a general discussion of several concepts of privacy and attempts at grounding privacy rights. In promoting and protecting the rights that participants in biobank research might have to privacy, it is argued that their interests should be related to the specific context of the provision and reception of health care that participation in biobank research is connected with. Rather than just granting participants an exclusive right to or ownership of their health information, which must be waived in order to make biobank research possible, the privacy aspect of health information should be viewed in light of the moral rights and duties that accompany any involvement in a research based system of health services.     

Moral Feedback and Motivation: Revisiting the Undermining Effect

Social psychologists have evidence that evaluative feedback on others’ choices sometimes has unwelcome negative effects on hearers’ motivation. Holroyd’s article (Holroyd J. Ethical Theory Moral Pract 10:267–278, 2007) draws attention to one such result, the undermining effect, that should help to challenge moral philosophers’ complacency about blame and praise. The cause for concern is actually greater than she indicates, both because there are multiple kinds of negative effect on hearer motivation, and because these are not, as she hopes, reliably counteracted by implicit features of praise and blame. The communicative ideal that she articulates does point us in the right direction, but it requires further elaboration. Once it is spelled out, we find that realizing this ideal, in light of the empirical research, requires rethinking the role of verdict-like judgments within moral feedback.

Life, death and (inter)subjectivity: realism and recognition in continental feminism

I begin with the assumption that a philosophically significant tension exists today in feminist philosophy of religion between those subjects who seek to become divine and those who seek their identity in mutual recognition. My critical engagement with the ambiguous assertions of Luce Irigaray seeks to demonstrate, on the one hand, that a woman needs to recognize her own identity but, on the other hand, that each subject whether male or female must struggle in relation to the other in order to maintain realism about life and death. No one can avoid the recognition that we are each given life but each of us also dies. In addition, I raise a more general, philosophical problem for analytic philosophers who attempt to read Continental philosophy of religion: how should philosophers interpret deliberately ambiguous assertions? For example, what does Irigaray mean in asserting, ‘Divinity is what we need to become free, autonomous, sovereign’? To find an answer, I turn to the distinctively French readings of the Hegelian struggle for recognition which have preoccupied Continental philosophers especially since the first half of the last century. I explore the struggle for mutual recognition between women and men who must face the reality of life and death in order to avoid the projection of their fear of mortality onto the other sex. This includes a critical look at Irigaray’s account of subjectivity and divinity. I turn to the French philosopher Michèle Le Doeuff in order to shift the focus from divinity to intersubjectivity. I conclude that taking seriously the struggle for mutual recognition between subjects forces contemporary philosophers of religion to be realist in their living and dying. With this in mind, the lesson from the Continent for philosophy of religion is that we must not stop yearning for recognition. Indeed, we must even risk our autonomy/divinity in seeking to recognize intersubjectivity.     

Student perceptions and motivation in the classroom: exploring relatedness and value

According to Self-Determination Theory, feelings of relatedness and value of a behavior are critical factors that affect internalization and integration. The purpose of the current study was to identify factors that influence relatedness and value in an academic setting. Specifically, the study investigated the effects of autonomy, mastery goals, performance-approach goals, and performance-avoidance goals, on two dependent variables: relatedness to the professor and value of the course. Participants were 222 undergraduate students (90 males) enrolled in introductory psychology classes. Linear regression analyses showed a statistically significant effect of mastery goals and autonomy on relatedness such that higher scores were associated with greater relatedness. A similar pattern emerged for value. Neither performance-approach nor performance-avoidance goals were significantly associated with relatedness or value. Theoretical and practical contributions are discussed.
