ABSTRACT

Abstract concepts differ from concrete concepts in several ways. Here, we focus on what we refer to as situational systematicity: The objects and relations that constitute an abstract concept (e.g., justice) are more dispersed through space and time than are those that typically constitute a concrete concept (e.g., chair); a larger set of objects and relations constitute an abstract concept than a concrete one; and exactly which objects and relations constitute a concept is more context-dependent for abstract concepts. We thus refer to abstract concepts as having low situational systematicity. We contend that situational systematicity, rather than abstractness per se, is a critical determinant of the cognitive, behavioural, and neural phenomena associated with concepts. Further, viewing concepts as schema provides insight into (i) the situation-based dynamics of concept learning and representation and (ii) the functional significance of the brain regions and their interactions that comprise the schema control network.

Notes

1 In fact, the greater activity in left IFG (and other left-lateralized frontal and temporal regions) often observed for abstract compared to concrete concepts in functional MRI studies has typically been interpreted in support of dual-coding theory and the role of language in representing abstract concepts (e.g., Binder et al., Citation2005; for meta-analyses, see Binder, Desai, Graves, & Conant, Citation2009; Wang et al., Citation2010), rather than as evidence of abstract concepts requiring greater top-down control (e.g., Hoffman et al., Citation2015).

2 Although down-regulated, these associations are central to enabling the system to generate individuated “tokens” of experience (distinguishing knowledge about the type of a thing, whether an object or an event, from knowledge about the token thing—the actual individuated object or event as grounded in a particular space and time; Altmann & Ekves, Citation2019).

3 We view as equivalent an approach in which a single concept such as sharing can refer to a range of situations and an approach in which sharing is a complex concept comprising several kinds of sharing (essentially corresponding to different, but overlapping, schemas); cf. polysemy.

4 Although most of the studies included in the meta-analysis conducted by Desai et al. (Citation2018) did not directly compare concrete and abstract concepts, the finding that we refer to here (depicted in Figure 3 of Desai et al.) compares results of an ALE meta-analysis collapsing across tasks that target several domains of abstract concepts with an ALE meta-analysis that attempts to include only tasks and contrasts targeting concrete concepts.

5 This was operationalized as the average abstractness in tweets containing at least four words from Brysbaert et al.’s (Citation2014) concreteness norms.
