Inspired by the Scottish Enlightenment philosopher Adam Ferguson, we explore how cultural and social organization arises from human action, but not human design: from myopic, moment-by-moment modifications to the rules by which we live—modifications intelligently chosen to solve current problems

Ross D. Kristensen-McLachlan, Pablo Contreras Kallens and I suggest that the introduction of Reinforcement Learning with Human Feedback provides much need socially informed feedback and that this makes their linguistic behavior more human-like (including human errors) 2/2

We propose a top-down, memory-based perspective on structural priming in which multiple contextual (including non-syntactic) constraints shape the representation of a sentence. This proposal resolves the anomalous empirical findings and accounts for structural priming in LLMs.

We review recent empirical work from within the structural priming literature itself and from research on LLMs that questions the standard view of what structural priming says about the mental representation of language. Instead we offer an alternative account rooted in basic memory processes.

I'm excited about this TICS Opinion with @yngwienielsen.bsky.social, challenging the view that structural priming—the tendency to reuse a recent syntactic structure—provides evidence for the psychological reality of grammar-based constituent structure.

And a final bonus meme: Laura Bridgman was the first person with no sight and hearing who learned how to communicate via finger spelling. She later taught Anne Sullivan who introduced Helen Keller to finger spelling. Yet, sadly, most are unaware of Laura Bridgman's pioneering role today.

The second third-place meme was about Harry Harlow's Pitt of Despair, which was used to illustrate one of the many reasons for why "the forbidden experiment" (involving bringing up children in isolation to see if they develop language) can never be done.

Two memes ended up in third place. The first one is about the McGurk effect in which an auditory /ba/ combined with the lip movements for "Ga" leads to the perception of a "Da".

The runner up was about a second topic that elicited several memes: The rapid turn-taking in everyday conversations

Every year at the end of the semester, I ask the students in my Psych of Language class to create memes about what they've learned. They then vote for their favorites.
Here's the winner about how the idea of a universal grammar is no longer as compelling as it once seemed.

We argue that the environment is constantly in flux and thus that SL therefore cannot be the end goal but rather provides a baseline against which novelty can be detected from random noise. We discuss the implications of this perspective for #CognitiveScience 2/2

What is human #StatisticalLearning for? The standard assumption is that the goal of SL is to learn the regularities in the environment to guide behavior. In our new Psych Review paper, we argue that SL instead is provides the basis for novelty detection within an information foraging system
