"Bayesian anchoring" and the fourfold pattern of risk attitudes
Experiments on decision making under uncertainty are known to display a classical pattern of risk aversion and risk seeking referred to as "fourfold pattern" (or "reflection effect") , but recent experiments varying the speed and order of mental processing have brought to light a more nuanced phenomenology.
Multi-tasking via baseline control in recurrent neural networks
Changes in an animal's behavioral state, such as arousal and movements, induce {complex modulations of the baseline input currents to sensory areas, eliciting sensory modality-specific effects.
Mechanisms for spontaneous symmetry breaking in developing visual cortex
For the brain to recognize local orientations within images, neurons must spontaneously break the translation and rotation symmetry of their response functions -- an archetypal example of unsupervised learning.
A theory of interpretive clustering in free recall
A stochastic model of short-term verbal memory is proposed, in which the psychological state of the subject is encoded as the instantaneous position of a particle diffusing over a semantic graph with a probabilistic structure.
The Role of Word Length in Semantic Topology
A topological argument is presented concering the structure of semantic space, based on the negative correlation between polysemy and word length.
