Phase Transitions in Binary Categorization: Evidence for Dual-System Decision Making.

  author={I. A. Lubashevsky and Ian Wilson and Rio Suzuki and Yuki Kato},
  journal={arXiv: Medical Physics},
We report experiment results on binary categorization of (i) gray color, (ii) speech sounds, and (iii) number discrimination. Data analysis is based on constructing psychometric functions and focusing on asymptotics. We discuss the transitions between two types of subjects' response to stimuli presented for two-category classification, e.g., visualized shade of gray into "light-gray" or "dark-gray." Response types are (i) the conscious choice of non-dominant category, described by the deep…

Interaction of Human Temporality and External World

This chapter finalizes the qualitative description of the complex present and the proposed multi-component time formalism of human actions contains two constituent components: human temporality with complex temporal structure and physical environment.



Gray Color Multi-Categorical Perception: Asymptotics of Psychometric Function

The results of conducted experiments on categorical perception with respect to gray color categorization into three classes are reported. Namely, the subjects were instructed to categorize shades of

Statistical Properties of Gray Color Categorization: Asymptotics of Psychometric Function

Conclusions about plausible mechanisms governing categorical perception, at least for the analyzed system, are drawn.

Activation in the neural network responsible for categorization and recognition reflects parameter changes

Little evidence is found that categorization and recognition recruit separate memory systems, and systematic effects of changes in parameters on patterns of brain activity are observed, which are interpretable in terms of differing forms of evidence accumulation that resulted from the changed parameter settings.

Memory, reasoning, and categorization: parallels and common mechanisms

It is argued that there is broad scope for crossover between the methods and theories developed for each task, and progress in all three of these fields will be expedited by further investigation of the many commonalities between these tasks.

The speed-accuracy tradeoff: history, physiology, methodology, and behavior

A “users guide” of SAT methodology is presented, including a critical review of common experimental manipulations and analysis techniques and a treatment of the typical behavioral patterns that emerge when SAT is manipulated directly.

Dual-processing accounts of reasoning, judgment, and social cognition.

This article reviews a diverse set of proposals for dual processing in higher cognition within largely disconnected literatures in cognitive and social psychology and suggests that while some dual-process theories are concerned with parallel competing processes involving explicit and implicit knowledge systems, others are concerns with the influence of preconscious processes that contextualize and shape deliberative reasoning and decision-making.

The contention that generalized magnitude processing is a more accurate conceptual description of how the brain deals with information about time, space, number and other dimensions is discussed.

The basic elements and potential building blocks for such theories, using sources in large measure from classical decision theory and game theory, are reviewed.

Fast guesses in choice reaction time

A model which describes the effect fast guesses must have on observable choice latencies and probabilities is developed, strengthened, and tested with encouraging results. With the model, it is
