A Comparative Study of the “Ideal Observer” in Meta-ethics and the “Divine Command” Theory
The two theories of “ideal observer” and “divine command” are theories on constructionism and voluntarism. According to the ideal theory, ethical realities are defined based on the attitudes of the assumed ideal observers and the foundation of these theories is formed on negation of the independent ethical realities. Therefore, existence of independent and evident ethical realities based on whi...
متن کاملQuantifying Stimulus Discriminability: A Comparison of Information Theory and Ideal Observer Analysis
Performance in sensory discrimination tasks is commonly quantified using either information theory or ideal observer analysis. These two quantitative frameworks are often assumed to be equivalent. For example, higher mutual information is said to correspond to improved performance of an ideal observer in a stimulus estimation task. To the contrary, drawing on and extending previous results, we ...
متن کاملUsing Ideal Observers in Higher-order Human Category Learning
Ideal observer models have proven useful in investigating assumptions about human information processing in a variety of perceptual tasks. However, these models have not been applied in the area of higher-order category learning. We describe a simple Bayesian ideal observer and apply it to empirical data on category learning. We describe an experiment in which we found that acquisition of famil...
متن کاملAn ideal observer analysis of visual working memory.
Limits in visual working memory (VWM) strongly constrain human performance across many tasks. However, the nature of these limits is not well understood. In this article we develop an ideal observer analysis of human VWM by deriving the expected behavior of an optimally performing but limited-capacity memory system. This analysis is framed around rate-distortion theory, a branch of information ...
متن کاملHuman and Ideal Observers for Detecting Image Curves
This paper compares the ability of human observers to detect target image curves with that of an ideal observer. The target curves are sampled from a generative model which specifies (probabilistically) the geometry and local intensity properties of the curve. The ideal observer performs Bayesian inference on the generative model using MAP estimation. Varying the probability model for the curve...
