Recently, swimming-style colour synaesthesia was introduced as a new form of synaesthesia. A synaesthetic Stroop test was used to establish its genuineness. Since Stroop interference can occur for any type of overlearned association, in the present study we used a modified Stroop test and psychophysiological synaesthetic conditioning to further establish the genuineness of this form of synaesthesia. We compared the performance of a swimming-style colour synaesthete and a control who was trained on swimming-style colour associations. Our results showed that behavioural (...) aspects of swimming-style colour synaesthesia can be mimicked in a trained control. Importantly, however, our results showed a psychophysiological conditioning effect for the synaesthete only. We discuss the theoretical relevance of swimming-style colour synaesthesia according to different models of synaesthesia. We conclude that swimming-style colour synaesthesia is a genuine form of synaesthesia, can be mimicked behaviourally in non-synaesthetes, and is best explained by a re-entrant feedback model.

Many accounts in environmental ethics converge on relationality as the catalyst of humans' responsibility towards other-than-human beings. But what exactly is relationality and how can the amorphous notion be specified? In search of a conceptual basis for human-animal relations, I show how questions about the nature of intersubjectivity are entwined with questions about the nature of reality. In my approach to answering these questions, I connect empirical results, insights from Edmund Husserl's phenomenology and from Jakob von Uexküll's theory of _Umwelten_. (...) Based on this synthesis, I explain how beings endowed with radically different subjective experiences–what I call organisms' respective realities–are nevertheless capable of meaningfully relating to one another and have their minds "merge" in intersubjective encounters. I conclude that relationality is a "real" possibility for mediating ethical action. (shrink)
