Memory Traces: Are Transformers Tulving Machines?
Memory traces–changes in the memory system that result from the perception and encoding of an event–were measured in pioneering studies by Endel Tulving and Michael J. Watkins in 1975 (Tulving and Watkins, 1975). These and further experiments informed the maturation of Tulving’s memory model, from the GAPS (General Abstract Processing System) to the SPI (Serial-Parallel Independent) model (Tulving, 1983). Having current top of the line LLMs revisit the original Tulving-Watkins tests may help in assessing whether foundation models completely instantiate or not this class of psychological models.

The Brain of Prof. Le Cun
In a remarkable paper (Le Cun, 2022) Turing Award recipient Yann Le Cun proposes a new cognitive architecture for intelligent agents. The selection of questions this architecture seeks to address is drawn from cognitive psychology (animal and human learning abilities and world understanding). It also dramatizes a strong conviction in the universality of gradient-based learning. We argue from confronting it to well-known studies in experimental psychology and recent results in neuroscience that the new architecture is both misleading and truly inspiring.
