Myearly fascination with geometry and physics and, later, with perception and imagination inspired a hope that fundamental phenomena of psychology, like those of physics, might approximate universal laws. Ensuing research led me to the following candidates, formulated in terms of distances along shortest paths in abstract representational spaces: Generalization probability decreases exponentially and discrimination time reciprocally with distance. Time to determine the identity of shapes and… 

Computational (Principles of) Psychology

This short intensive course states, motivates, and offers detailed support to the observation that cognition is fundamentally a computational process [26]. Students are introduced to a number of

If Mathematical Psychology Did Not Exist We Might Need to Invent It: A Comment on Theory Building in Psychology

It is argued that psychological theory building is not a statistical problem, mathematical formalism is beneficial to theory, measurement and theory have a complex relationship, rewriting old theory can yield new insights, and theory growth can drive empirical work.

If mathematical psychology did not exist we would need to invent it: A case study in cumulative theoretical development

It is commonplace, when discussing the subject of psychological theory, to write articles from the assumption that psychology differs from physical sciences in that we have no psychological theories

The Step to Rationality: The Efficacy of Thought Experiments in Science, Ethics, and Free Will

The evolutionary emergence in humans of deeply internalized implicit knowledge of abstract principles of transformation and symmetry may have been crucial for humankind's step to rationality-including the discovery of universal principles of mathematics, physics, ethics, and an account of free will that is compatible with determinism.

The physics of now

The origin of this division in terms of simple models of information gathering and utilizing systems (IGUSs) is discussed, where past, present, and future are not properties of four-dimensional spacetime but notions describing how individual IGUSs process information.

Extending Fitts’ law to more than one dimension has been recognized as having important implications for HCI. In spite of the progress made over the years, however, it is still far from a resolved

Using multidimensional scaling to quantify similarity in visual search and beyond

A method whereby MDS can be repurposed to successfully quantify the similarity of experimental stimuli is proposed, thereby opening up theoretical questions in visual search and attention that cannot currently be addressed.

Multidimensional scaling.

Key aspects of performing MDS are discussed, such as methods that can be used to collect similarity estimates, analytic techniques for treating proximity data, and various concerns regarding interpretation of the MDS output.

From Physical Time to a Dualistic Model of Human Time

A dualistic model of human time is proposed in which each component has both an illusory and non-illusory (‘real’) aspect and provides experimental evidence for various spacetime cosmological assertions regarding human time.



Perceptual-cognitive universals as reflections of the world.

The universality, invariance, and elegance of principles governing the universe may be reflected in principles of the minds that have evolved in that universe--provided that the mental principles are

Symmetry, Causality, Mind

Time, our lost dimension: toward a new theory of perception, attention, and memory.

A theory of perception and attention that emphasizes the relational nature of perceptual invariants is developed within the context of auditory pattern research, and offers a general framework for understanding diverse phenomena thai range from speech perception and aphasia to sleep, growth, and time eslimation.

Generalization, similarity, and Bayesian inference.

Here Shepard's theory is recast in a more general Bayesian framework and it is shown how this naturally extends his approach to the more realistic situation of generalizing from multiple consequential stimuli with arbitrary representational structure.

Toward a universal law of generalization for psychological science.

A psychological space is established for any set of stimuli by determining metric distances between the stimuli such that the probability that a response learned to any stimulus will generalize to

Ecological constraints on internal representation: resonant kinematics of perceiving, imagining, thinking, and dreaming.

Chasles's theorem constrains the motion of each semirigid part of a body, during each moment of time, to a simple, six-degrees-of-freedom twisting motion, including the limiting cases of pure rotations or translations.

Connectionist Implementation of a Theory of Generalization

A natural connectionist implementation of the generalization theory is described, and how implications of the theory for generalization, discrimination, and classification learning can be explored by connectionist simulation is illustrated.

The magical number seven plus or minus two: some limits on our capacity for processing information.

The theory provides us with a yardstick for calibrating the authors' stimulus materials and for measuring the performance of their subjects, and the concepts and measures provided by the theory provide a quantitative way of getting at some of these questions.
