Changing concepts of working memory
Working memory is widely considered to be limited in capacity, holding a fixed, small
number of items, such as Miller's' magical number'seven or Cowan's four. It has recently …

Representation and computation in visual working memory
The ability to sustain internal representations of the sensory environment beyond immediate
perception is a fundamental requirement of cognitive processing. In recent years, debates …

Factorial comparison of working memory models.
Three questions have been prominent in the study of visual working memory limitations:(a)
What is the nature of mnemonic precision (eg, quantized or continuous)?(b) How many …

[HTML][HTML] Rate–distortion theory and human perception
CR Sims - Cognition, 2016 - Elsevier
The fundamental goal of perception is to aid in the achievement of behavioral objectives.
This requires extracting and communicating useful information from noisy and uncertain …

Efficient data compression in perception and perceptual memory.
Efficient data compression is essential for capacity-limited systems, such as biological
perception and perceptual memory. We hypothesize that the need for efficient compression …

Interactions between visual working memory representations
We investigated whether the representations of different objects are maintained
independently in working memory or interact with each other. Observers were shown two …

Compositional inductive biases in function learning
How do people recognize and learn about complex functional structure? Taking inspiration
from other areas of cognitive science, we propose that this is achieved by harnessing …

Chunking as a rational strategy for lossy data compression in visual working memory.
The nature of capacity limits for visual working memory has been the subject of an intense
debate that has relied on models that assume items are encoded independently. Here we …

Noisy and hierarchical visual memory across timescales
Both in everyday life and in memory research, people tend to think that items are 'held'in
mind, in the same way that a real-world object can be held in one's hand. Inspired by this …

Adaptive allocation of human visual working memory capacity during statistical and categorical learning
Human brains are finite, and thus have bounded capacity. An efficient strategy for a capacity-
limited agent is to continuously adapt by dynamically reallocating capacity in a task …
