Win Stay, Lose Shift as well as imitation strategies for iterated games rely on an aspiration level. With both learning rules a move is repeated unless the pay-o fell short of the aspiration level. I investigate social adaptation mechanisms for the aspiration level and their impact on the eÆciency of learning in a large population of agents that repeatedly play one round of a symmetric 2 2 game...

Background. A soccer ball is the principal piece of sports equipment for soccer and original brands compete with each other for a big pie of the market. Objectives. The aim of this study’s interpretive structural model (ISM) was to ascertain the factors that affect the intent to purchase original brand soccer balls. Methods.

A class of binary decision-making tasks called the two-alternative forced-choice task has been used extensively in psychology and behavioral economics experiments to investigate human decision making. The human subject makes a choice between two options at regular time intervals and receives a reward after each choice; for a variety of reward structures, these experiments showconvergence of the...

Lewis-Skyrms signaling games (Lewis 1969; Skyrms 2010) have been studied under a variety of low-rationality learning dynamics (Barrett 2006; Barrett and Zollman 2009; Huttegger, Skyrms, Smead, and Zollman 2010; Huttegger, Skyrms, Tarrès, and Wagner 2014; Huttegger, Skyrms, and Zollman 2014). Reinforcement dynamics are stable but slow and prone to evolving suboptimal signaling conventions. A low...
