The meaning of biological signals.
2020
We introduce the virtual special issue on content in signalling systems. The issue explores the uses and limits of ideas from evolutionary game theory and information theory for explaining the content of biological signals. We explain the basic idea of the Lewis-Skyrms sender-receiver framework, and we highlight three key themes of the issue: (i) the challenge of accounting for deception, misinformation and false content, (ii) the relevance of partial or total common interest to the evolution of meaningful signals, and (iii) how the sender-receiver framework relates to teleosemantics.
Modeling Developmental Processes in Psychology
2013
In the present article I suggest first that modeling in psychology can be described as an interactive process between a phenomenon under study (reality) and different levels of theoretical conceptualizations that vary in respect to how directly they can be related to empirical observations and at what level of generalization they operate. Then, I give three examples of my own work concerning building theories and testing models. Next, I discuss some caveats scientists face when building theories and models on the basis of their observations. Finally, I make a few conclusions on the basis of the article. peerReviewed
Receptive Reason: Alexander of Aphrodisias on Material Intellect
2010
AbstractAccording to Alexander of Aphrodisias, our potential intellect is a purely receptive capacity. Alexander also claims that, in order for us to actualise our intellectual potentiality, the intellect needs to abstract what is intelligible from enmattered perceptible objects. Now a problem emerges: How is it possible for a purely receptive capacity to perform such an abstraction? It will be argued that even though Alexander’s reaction to this question causes some tension in his theory, the philosophical motivation for it is a sound one. Rather than a calculation of actualities and potentialities, the doctrine of receptivity is supposed to explain how human beings come to grasp universal…
Spring School on Language, Music, and Cognition: Organizing Events in Time
2018
The interdisciplinary spring school “Language, music, and cognition: Organizing events in time” was held from February 26 to March 2, 2018 at the Institute of Musicology of the University of Cologne. Language, speech, and music as events in time were explored from different perspectives including evolutionary biology, social cognition, developmental psychology, cognitive neuroscience of speech, language, and communication, as well as computational and biological approaches to language and music. There were 10 lectures, 4 workshops, and 1 student poster session.Overall, the spring school investigated language and music as neurocognitive systems and focused on a mechanistic approach exploring…
Shallow Reductionism and the Problem of Complexity in Psychology
2008
In his recent book The Mind Doesn't Work That Way, Fodor argues that computational modeling of global cognitive processes, such as abductive everyday reasoning, has not been successful. In this article the problem is analyzed in the framework of algorithmic information theory. It is argued that the failed approaches are characterized by shallow reductionism, which is rejected in favor of deep reductionism and nonreductionism.
Expertise in folk music alters the brain processing of Western harmony
2012
In various paradigms of modern neurosciences of music, experts of Western classical music have displayed superior brain architecture when compared with individuals without explicit training in music. In this paper, we show that chord violations embedded in musical cadences were neurally processed in a facilitated manner also by musicians trained in Finnish folk music. This result, obtained by using early right anterior negativity (ERAN) as an index of harmony processing, suggests that tonal processing is advanced in folk musicians by their long-term exposure to both Western and non-Western music.
Practiced musical style shapes auditory skills
2012
Musicians' processing of sounds depends highly on instrument, performance practice, and level of expertise. Here, we measured the mismatch negativity (MMN), a preattentive brain response, to six types of musical feature change in musicians playing three distinct styles of music (classical, jazz, and rock/pop) and in nonmusicians using a novel, fast, and musical sounding multifeature MMN paradigm. We found MMN to all six deviants, showing that MMN paradigms can be adapted to resemble a musical context. Furthermore, we found that jazz musicians had larger MMN amplitude than all other experimental groups across all sound features, indicating greater overall sensitivity to auditory outliers. Fu…
Dades massives i estadística: La perspectiva d'un estadístic
2014
Les dades massives (big data) representen un recurs sense precedents per a afrontar reptes científics, econòmics i socials, però també incrementen la possibilitat de traure conclusions enganyoses. Per exemple, l’ús d’enfocaments basats exclusivament en dades i que es despreocupen de comprendre el fenomen en estudi, que s’orienten a un objectiu esmunyedís i canviant, que no tenen en compte problemes determinants en la recopilació de dades, que resumeixen o «cuinen» inadequadament les dades i que confonen el soroll amb el senyal. Repassarem alguns casos reeixits i il·lustrarem com poden ajudar els principis de l’estadística a obtenir una informació més fiable de les dades. També abordarem els…
Consumption patterns, development and growth: Adam Smith, David Ricardo and Thomas Robert Malthus
2003
In this paper we combine the classical analysis of luxury consumption with the classical theories of development and growth. We also focus on the role played, within classical economics, by institutional factors such as the structure of property rights and contractual arrangements in determining consumption patterns and investment in agriculture. In particular, we show that Ricardo's and Malthus' different views on the role of consumption expenditure in promoting growth depend on Ricardo's acceptance (Malthus' refusal) of Say's law of markets and on Ricardo's exclusion (Malthus' inclusion) of a non-commodity option such as leisure from (in) the range of available consumption alternatives.
Positional goods and social welfare: a note on George Pendleton Watkins’ neglected contribution
2018
Watkins's analysis of adventitious utility contains many aspects that are connected to the contemporary debate on positional goods. First, Watkins adventitious utility emerges from a process of social exclusion and can create negative externalities, in the sense that positive consumption of one individual implies negative consumption by another individual. Not only it creates negative externalities on other individuals, but it can initiate a race-to-the-bottom, where individuals waste an increasing amount of money on goods which do not possess any real utility.
