• Abstract summary: We take the first step by predicting human performance in the semantic fluency task (SFT), a well-studied task in cognitive science. We report preliminary evidence suggesting that, despite obvious implementational differences, TLMs can be used to identify individual differences in human fluency task behaviors. We discuss the implications of this work for cognitive modeling of knowledge representations.

• Abstract: Can deep language models be explanatory models of human cognition? If so, what are their limits? In order to explore this question, we propose an approach called hyperparameter hypothesization that uses predictive hyperparameter tuning in order to find individuating descriptors of cognitive-behavioral profiles. We take the first step in this approach by predicting human performance in the semantic fluency task (SFT), a well-studied task in cognitive science that has never before been modeled using transformer-based language models (TLMs). In our task setup, we compare several approaches to predicting which word an individual performing SFT will utter next. We report preliminary evidence suggesting that, despite obvious implementational differences in how people and TLMs learn and use language, TLMs can be used to identify individual differences in human fluency task behaviors better than existing computational models, and may offer insights into human memory retrieval strategies -- cognitive process not typically considered to be the kinds of things TLMs can model. Finally, we discuss the implications of this work for cognitive modeling of knowledge representations.

  We study the ability to skip steps in reasoning. Unlike humans, who may skip steps to enhance efficiency or to reduce cognitive load, models do not possess such motivations. Our work presents the first exploration into human-like step-skipping ability.

  We introduce a novel alignment technique in which we fine-tune a language model to implicitly optimize the parameters of a linear regressor. Using words as a test case, we evaluate our technique across multiple model sizes and datasets. We find an inverse relationship between psychometric power and a model's performance on downstream NLP tasks as well as its perplexity on held-out test data.

  Pretrained language models (PLMs) have made significant strides in various natural language processing tasks. The lack of interpretability due to their black-box'' nature poses challenges for responsible implementation. We propose a novel approach to interpreting PLMs by employing high-level, meaningful concepts that are easily understandable for humans.

  Non-human-like behaviour of contemporary pre-trained language models (PLMs) is a leading cause undermining their trustworthiness. A striking phenomenon is the generation of inconsistent predictions, which produces contradictory results. We propose a practical approach that alleviates the inconsistent behaviour issue by improving PLM awareness.

  We investigate the notion of model parameter identifiability through a case study focused on parameter estimation from motion sensor data. We employ a deep neural network to estimate subject-wise parameters, including mass, stiffness, and equilibrium leg length. The results show that while certain parameters can be identified from the observation data, others remain unidentifiable.

  We show that large language models can be turned into cognitive models. These models offer accurate representations of human behavior, even outperforming traditional cognitive models in two decision-making domains. Taken together, these results suggest that large, pre-trained models can be adapted to become generalist cognitive models.
