In recent years, the growing scientific interest in design has led to great advances in our knowledge of authentic design processes. However, as these findings go counter to the existing theories in both design research and cognitive science, they pose a serious challenge for both disciplines: there is a wide gap between what the existing theories predict and what designers actually do. At the same time, there is a growing movement of research on authentic cognitive activities, which has among other (...) things documented the central roles of action and the physical environment in these activities, something that existing cognitive theories have overlooked and cannot properly account for. This creates an explanatory gap analogous to the one found in design. This book aims to fill both of these gaps with a cognitive theory of how designers work. It revolves around the roles of physical activities and working materials in design, and the theory explains at length how these have functions that are essential to cognition. The two threads of design and cognition run in parallel throughout the book: the cognitive theory is applied to design, but is also consistently related to cognition in general. The result is, in back cover text parlance, a 'provocative' account of cognition and human performance, which should be of interest to cognitive scientists as well as to design researchers. (shrink)

The aim of this article is to present an evolutionarily grounded explanation of why we speak in sentences. This question is seldomly addressed, neither in the Chomskian tradition nor in cognitive linguistics. I base my explanation on an analysis of different levels of communication. I identify four levels: praxis, instruction, coordination of common ground and coordination of meaning. The analysis will be focused on the evolutionary benefits of communicating about events as a way of coordinating actions. A cognitively grounded model (...) of events will be outlined. My central thesis is that the communicative role of sentences is to express events. (shrink)

The first hurdle to overcome in approaching the complex topic of the relation between language and consciousness is terminology. So let me begin, in good philosophical style, by explaining the senses in which I use the three lexical terms in the title. Luckily I need not explain those of the three grammatical words the, of, and on: there is probably a minor library of semantic literature devoted to that. I need not, since I both know their meanings pre-theoretically, and know (...) that my readers, as users of English, know them. The significance of this simple fact concerning the meaning of all everyday words, in everyday constructs, is something that I will return to, since it plays a central role in the argument in Section 2. However, with abstract, theoretically loaded nominalizations such as dependence, language, and most of all consciousness, we need to beware since we cannot assume common knowledge -- myriads of misunderstandings arise since we mean somewhat different 'things' by them. I start with the easiest, by which I mean specifically ' dependence of language on consciousness', explaining only afterward what I mean by the latter terms. I ask the reader to bear this circularity with me. (shrink)

In this paper, I argue that the notion of ‘context' that has to be used in the study of indexicals is far from univocal. A first distinction has to be made between the real context of speech and the context in which the speech act is supposed to take place — only the latter notion being relevant when it comes to determining the semantic values of indexicals. Second, we need to draw a distinction between the context of the locutionary act (...) and the context of the illocutionary act: contrary to a standard assumption of speech act theory, they can diverge, and their possible divergence explains a number of puzzling phenomena involving indexicals.

The effects of utterances such as cue phrases, keep-turn markers, and grounding signals cannot be characterized as changes to a shared record of the propositions under discussed: the simplest (and arguably most natural) way of characterizing the meaning of these utterances is in terms of a theory in which the conversational score is seen as a record of the discourse situation, or at least of the speech acts that have been performed. The problem then becomes to explain how discourse entities (...) are accessible. We consider three hypotheses about the dynamics of a speech act-based theory of the conversational score, and argue that they could be implemented with relatively minor modifications to the technical tools already introduced in theories such as Compositional DRT.

The neuropeptide oxytocin has been suggested to facilitate social cognition and behavior. Therefore, published literature mainly focuses on the study of OT in a social context or in relation to others. But how we think, act and feel in social situations might strongly depend on our own state of being – the self. Thus, the present three studies examine the effects of OT on self-related processing and cognition. The first study explores the idea that OT might decrease self-related information processing, (...) even when individuals are specifically exposed to being self-aware. We could show that public self-awareness was increased when participants were placed in front of a mirror. Moreover, in the placebo group, lower scores in self-esteem were associated with increased self-awareness. This was not the case in the OT group in which self-esteem was unrelated to self-awareness. The results suggest that OT might function as a buffer against the negative consequences of enhanced self-related processing. The second study of this dissertation explores OT’s effects on self-related processing in a more physiological approach. Participants were to conduct a heartbeat perception task in front of a mirror and we hypothesized OT to inhibit interoceptive awareness. Usually, people become more attuned to bodily responses in front of a mirror due to increased self-awareness. In line with the concept of de-individuation under OT, we could show that heartbeat accuracy, and thus interoceptive accuracy, was increased among participants under placebo who were placed in front of the mirror, but no such effect occurred after treatment with OT. The third study provides empirical evidence testing OT’s effect on situational self-awareness when attentional focus is shifted, either to external sensory perception or explicit self-related cognition, using a categorization vs. introspection task. The results suggest that situational self-awareness was reduced after OT treatment compared to placebo, when participants had previously been instructed to introspect about their feelings. In sum, all findings support the idea of OT being significantly involved in self-related processing and cognition by enhancing de-individuation. (shrink)
