Affordances can invite behavior: Reconsidering the relationship between affordances and agency

The concept of agency has been central to ecological approaches to psychology. Gibson, one of the founders of this movement, made room for this concept by arguing against the mechanistic conceptions in psychology. In his view, the environment is not a collection of causes that pushes the animal around, but consist of action possibilities, which he coined affordances. In making their way in the world, animals regulate their behavior with respect to these possibilities. Reed later developed this ecological conception of agency, following Gibson in conceiving of affordances as action possibilities. However, drawing upon industrial design, architecture, and phenomenology, we argue that affordances are not mere action possibilities but that they can also invite behavior. We suggest a mutualist perspective on invitations, suggesting that they depend on the animal-environment relationship in multiple dimensions. The implications of this new conception of affordances for the ecological account of agency are explored.     

An Intuitionistic Reformulation of Mally’s Deontic Logic

In 1926, Ernst Mally proposed a number of deontic postulates. He added them as axioms to classical propositional logic. The resulting system was unsatisfactory because it had the consequence that A is the case if and only if it is obligatory that A. We present an intuitionistic reformulation of Mally’s deontic logic. We show that this system does not provide the just-mentioned objectionable theorem while most of the theorems that Mally considered acceptable are still derivable. The resulting system is unacceptable as a deontic logic, but it does make sense as a lax logic in the modern sense of the word.     

Does habit strength moderate the intention–behaviour relationship in the Theory of Planned Behaviour? The case of fruit consumption

The present study examined if habit strength moderated the influence of intention on fruit consumption in a Dutch adult sample (N?=?521, 46.3% males, mean age?=?34.50, SD?=?10.87), using the theoretical relations of the Theory of Planned Behaviour (TPB). TPB variables and habit strength were assessed at baseline. Fruit consumption was assessed with a validated questionnaire five weeks later. Three groups were created: low habit strength (n?=?180), medium habit strength (n?=?185) and high habit strength (n?=?156). Confirmatory factor analyses and multi-group path analyses were performed using AMOS 4.0. A good fit was obtained for the overall measurement model and the structural models. Multi-group path analyses showed that intention was a significant predictor of fruit consumption in the low habit (β?=?0.36, p?<?0.001) and medium habit group (β?=?0.30, p?<?0.001), but a non-significant predictor in the high habit group (β?=?0.05, p?=?0.596). Implications for information-based and motivation-based interventions are discussed.     

Creative cities: Breeding places in the knowledge economy

This paper explores the function of cities in the knowledge economy. The knowledge economy asks for “creative cities,” i.e. competitive urban areas that combine concentration, diversity, instability and a positive reputation. For a review of the concept of creative cities from a historical and theoretical perspective, we draw the conclusion that knowledge, creativity and innovation cannot be planned from scratch by local governments. However, creative cities par excellence such as Austin, the Øresund and Barcelona demonstrate that local policymakers in fact can play a part in preparing cities for the requirements of the knowledge economy. We conclude that local governments can increase the chance that urban creativity emerges by providing the appropriate underlying framework conditions.     

Engineering and the Problem of Moral Overload

When thinking about ethics, technology is often only mentioned as the source of our problems, not as a potential solution to our moral dilemmas. When thinking about technology, ethics is often only mentioned as a constraint on developments, not as a source and spring of innovation. In this paper, we argue that ethics can be the source of technological development rather than just a constraint and technological progress can create moral progress rather than just moral problems. We show this by an analysis of how technology can contribute to the solution of so-called moral overload or moral dilemmas. Such dilemmas typically create a moral residue that is the basis of a second-order principle that tells us to reshape the world so that we can meet all our moral obligations. We can do so, among other things, through guided technological innovation.     

Neuroticism,conscientiousness and fruit consumption: Exploring mediator and moderator effects in the theory of planned behaviour

Integrating the theory of planned behaviour (TPB) with the five-factor model (FFM) of personality may provide insight into the cognitive and motivational mechanisms linking personality with health behaviour, but this issue has received very little attention regarding fruit consumption. Mediator effects of TPB concepts in the personality–fruit consumption link, as well as moderator effects of personality in the intention–fruit consumption link, were therefore investigated in the present study. Data on fruit consumption, TPB concepts and FFM dimensions were gathered among 405 respondents in face-to-face interviews using questionnaires. Structural equation modelling was used to investigate the mediator and moderator effects. The direct effect of conscientiousness on fruit consumption was mediated by attitude and perceived behavioural control, while no direct effect of neuroticism on fruit consumption was found. Neuroticism moderated the intention–fruit consumption relationship with the weakest relationship for those scoring high on neuroticism. Conscientiousness did not moderate the intention–fruit consumption relationship. TPB variables are mediators in the conscientiousness–fruit consumption link. Whether fruit consumption is intentional may be dependent upon the personality dimension neuroticism. Personality dimensions may be a useful addition to the TPB and should be considered in health behaviour change interventions.     

The Letter and the Witness: Agamben,Heidegger, and Derrida

In Remnants of Auschwitz, Agamben introduces a particular conception of bearing witness to overcome the problems contained in an account of language that depends on the voice or the letter. From his earlier work, it is clear that his critique of the voice and the letter is not only directed to ancient and medieval metaphysics, but also concerns Heidegger's account of the voice and Derrida's account of the letter and writing. Yet, if Agamben is correct in claiming that bearing witness offers an alternative to Heidegger's voice and Derrida's letter, it is remarkable – a fact unnoticed in the available literature – that Agamben does not discuss how these conceptions of the voice and the letter are intrinsically connected to the problem of testimony for Heidegger as well as Derrida. To show how this lack of attention to bearing witness in Heidegger and Derrida affects Agamben's critique, this article proceeds as follows. First, we interpret Agamben's critique of Heidegger's conception of the voice and Derrida's conception of writing in terms of the presuppositional constitution of metaphysics. Second, we describe Agamben's concept of the witness and indicate how it offers an alternative to this presuppositional constitution of metaphysics. Finally, we show which role bearing witness plays in Heidegger's voice and Derrida's letter, and how our analysis presents a more precise version of Agamben's critique.
