The geometry vs. the algebra of meaning

In this paper Gärdenfors’s geometric approach to meaning in natural language is compared to Jackendoff's algebraic one, and this is done against the backdrop of formal semantics. Ultimately, the paper tries to show that Jackendoff's framework is to be preferred to all others. The paper proceeds as follows. In Section 2, the common theoretical commitments of Gärdenfors and Jackendoff are outlined, and it is attempted to argue briefly that they are on the right track. In Section 3, the basics of the two frameworks to be compared are laid out, and it is assessed how they deal with some central issues in semantic theory, namely reference and truth, lexical decomposition, and compositionality. In Section 4, we get into the nitty-gritty of how Gärdenfors and Jackendoff actually proceed in semantic analysis, using an example of a noun and a verb (embedded in a sentence). In Section 5, the merits of Gärdenfors's empiricism when it comes to word learning and concept acquisition are assessed and compared to the moderate nativism of Jackendoff, and it is argued that Jackendoff's nativism is to be preferred. In the sixth section, the semantic internalism common to both frameworks is commented on.

Bootstrapping of integer concepts: the stronger deviant-interpretation challenge (and how to solve it)

Beck (Cognition 158:110–121, 2017) presents an outline of the procedure of bootstrapping of integer concepts, with the purpose of explicating the account of Carey (The Origin of Concepts, 2009). According to that theory, integer concepts are acquired through a process of inductive and analogous reasoning based on the object tracking system (OTS), which allows individuating objects in a parallel fashion. Discussing the bootstrapping theory, Beck dismisses what he calls the "deviant-interpretation challenge"—the possibility that the bootstrapped integer sequence does not follow a linear progression after some point—as being general to any account of inductive learning. While the account of Carey and Beck focuses on the OTS, in this paper I want to reconsider the importance of another empirically well-established cognitive core system for treating numerosities, namely the approximate number system (ANS). Since the ANS-based account offers a potential alternative for integer concept acquisition, I show that it provides a good reason to revisit the deviant-interpretation challenge. Finally, I will present a hybrid OTS-ANS model as the foundation of integer concept acquisition and the framework of enculturation as a solution to the challenge.

Not rational, but not brutely causal either: A reply to Fodor on concept acquisition

Jerry Fodor has argued that concept acquisition cannot be a psychological or “rational-causal” process, but can only be a “brute-causal” process of acquisition. This position generates the “doorknob --> DOORKNOB” problem: why are concepts typically acquired on the basis of experience with items in their extensions? I argue that Fodor’s taxonomy of causal processes needs supplementation, and characterize a third type: what I call “intelligible-causal processes.” Armed with this new category I present what I regard as a better response than Fodor’s to the doorknob --> DOORKNOB problem.

Comment: A role of Language in Infant Emotion Concept Acquisition

Ruba and Repacholi (2020) review an important debate in the emotion development literature: whether infants can perceive and understand facial configurations as instances of discrete emotion categories. Consistent with a psychological constructionist account (Lindquist & Gendron, 2013; Shablack & Lindquist, 2019), they conclude that infants can perceive valence on faces, but argue the evidence is far from clear that infants perceive and understand discrete emotions. Ruba and Repacholi outline a novel developmental trajectory of emotion perception and understanding in which early emotion concept learning may be language-independent. In this comment, we argue that language may play a role in emotion concept acquisition even prior to children’s ability to produce emotion labels. We look forward to future research addressing this hypothesis.

From Commonplaces to Consciousness

In many ways, the transformative character of developing critical consciousness reflects the dynamics of acquiring threshold concepts. Drawing from research into threshold concept acquisition, the author argues that critical first-year composition instruction can more effectively scaffold students into critical perspectives by linking critical pedagogy more closely with efforts to develop students’ rhetorical meta-awareness of writing.
