Investigating representations of conceptual components from a frame-theoretic perspective


How are concepts represented in our minds? The concept of TOMATO, for instance, might contain information such as its typical shape, taste or colour. Is there an interaction between the structure of these representations in our memory and our ability to find the right word corresponding to a concept, that is, lexical access to the word "tomato"? As part of Project A04 of the SFB991, we investigate these questions from a frame-theoretic perspective on conceptual representation (Löbner, 2014; Barsalou, 1992). According to frame theory, knowledge is represented in the form of recursive attribute-value structures. The conceptual frame for TOMATO, for instance, might contain attribute-value pairs such as shape – round or colour – red. In my dissertation project, we are interested in the cognitive status of attributes in frames, and how conceptual frame representations are activated and interact with preceding and subsequent processing stages in language production.


In this talk, I will present a series of experiments using Event-Related Potentials (ERPs) in combination with a picture-naming task to study these research questions. Our experiments focus on whether it is possible to pre-activate conceptual components (such as colour) in a semantic-priming paradigm, and whether this activation has consequences for lexical access as indicated by the P2 component in the ERPs (e.g., Strijkers, Costa, & Thierry, 2010; Costa, Strijkers, Martin, & Thierry, 2009). I will present results from two studies suggesting that pre-activation of the colour attribute hinders lexical access, and discuss some of the theoretical consequences for conceptual representation.
