Modeling Imageless Thought: The Relative Judgment Theory of Numerical Comparisons
نویسنده
چکیده
The mental process of comparing numbers is shown to follow the principles of Relative Judgment Theory. Martingale predictions of the theory are confirmed in an extensive study of numerical comparisons using the Method of Symmetric Differences. The theory is then used as a tool to reveal the Psychonumeric Function relating psychological difference to numerical difference. This function transforms a difference between numbers into a sextal valued (0, 1,2, 3,4, 5) number with zero as a unit psychonumeric value. The Psychonumeric Function combined with the theory’s prediction of response times gives a close account of the numerical comparison Chronometric Function.

متن کاملMODELING RISK OF LOSING A CUSTOMER IN A TWO-ECHELON SUPPLY CHAIN FACING AN INTEGRATED COMPETITOR: A GAME THEORY APPROACH
In a competitive market, customer decision is made to maximize his utility. It can be assumed that risk of losing a supply chain’s customer can be defined based on products utility from customer point of view. This paper takes account of product price and service level as competition criteria. The proposed model is based on non-cooperative game theory, for one-manufacturer and one-retailer supp...
