Preflexes and internal models in biomimetic robot systems

The next generation of neuroprostheses, which are aimed at the restoration of natural movement of paralysed body parts or at the natural interaction with external devices, will be quite similar to biomimetic robot systems which attempt to duplicate the organization of the biological motor control system. In the paper, we review some of the organizing principles that have emerged in the last few years and might provide useful guidelines for a biomimetic design.     

The developmental roots of fairness: infants' reactions to equal and unequal distributions of resources

The problem of how to distribute available resources among members of a group is a central aspect of social life. Adults react negatively to inequitable distributions and several studies have reported negative reactions to inequity also in non-human primates and dogs. We report two experiments on infants' reactions to equal and unequal distributions. In two experiments, infants' looking times and manual choices provide, for the first time, converging evidence suggesting that infants aged 12 to 18 months (mean age 16 months) attend to the outcomes of distributive actions to evaluate agents' actions and to reason about agents' dispositions. The results provide support for recent theoretical proposals on the developmental roots of social evaluation skills and a sense of fairness.     

Differentiation of Self and Dyadic Adjustment in Couple Relationships: A Dyadic Analysis Using the Actor‐Partner Interdependence Model

Bowen's multigenerational theory provides an account of how the internalization of experiences within the family of origin promotes development of the ability to maintain a distinct self whilst also making intimate connections with others. Differentiated people can maintain their I‐position in intimate relationships. They can remain calm in conflictual relationships, resolve relational problems effectively, and reach compromises. Fusion with others, emotional cut‐off, and emotional reactivity instead are common reactions to relational stress in undifferentiated people. Emotional reactivity is the tendency to react to stressors with irrational and intense emotional arousal. Fusion with others is an excessive emotional involvement in significant relationships, whilst emotional cut‐off is the tendency to manage relationship anxiety through physical and emotional distance. This study is based on Bowen's theory, starting from the assumption that dyadic adjustment can be affected both by a member's differentiation of self (actor effect) and by his or her partner's differentiation of self (partner effect). We used the Actor‐Partner Interdependence Model to study the relationship between differentiation of self and dyadic adjustment in a convenience sample of 137 heterosexual Italian couples (nonindependent, dyadic data). The couples completed the Differentiation of Self Inventory and the Dyadic Adjustment Scale. Men's dyadic adjustment depended only on their personal I‐position, whereas women's dyadic adjustment was affected by their personal I‐position and emotional cut‐off as well as by their partner's I‐position and emotional cut‐off. The empirical and clinical implications of the results are discussed.     

Laboratory Ritual: Experimentation and the Advancement of Science

Technical achievement in laboratories requires millennia–old ritual formulations; the methodological expectations and presuppositions of scientists stem not only from investigations of the last three centuries but also from the ritual knowledge making that has governed human religion. Laboratory research is a form of human ritual open to interpretation in the manner of religious ritual. The experiments of the laboratory are fact–gathering ventures, but the integration of that knowledge into our general understanding of a universe of information networks is the process of knowledge making, and it is the highest achievement of all rituals, be they religious or scientific. Ritual theory offers insight into the nature of scientific experimentation.     

Molyneux' question redux

After more than three centuries, Molyneux's question continues to challenge our understanding of cognition and perceptual systems. Locke, the original recipient of the question, approached it as a theoretical exercise relevant to long-standing philosophical issues, such as nativism, the possibility of common sensibles, and the empiricism-rationalism debate. However, philosophers were quick to adopt the experimentalist's stance as soon as they became aware of recoveries from congenital blindness through ophtalmic surgery. Such recoveries were widely reported to support empiricist positions, suggesting that the question had found its empirical answer. Contrary to this common view, we argue that studies of patients recovering from early blindness through surgery cannot provide an answer. In fact, because of the very nature of such ophtalmological interventions it is impossible to test the question in the empirical conditions outlined by Molyneux. Thus we propose that Molyneux's question be treated as an early thought experiment of a specific kind. Although thought experiments of this kind cannot be turned into actual experimental conditions, they provide a conceptual restructuring of theories. Such restructuring in turn leads to new predictions that can then be tested by normal experiments. In accord with this interpretation, we show that Molyneux's question can be analyzed into a hierarchy of specific questions about vision in its phenomenal and sensory-motor components. Some of these questions do lead to actual experimental conditions that could be studied empirically.
