The gift-exchange game is a form of sequential prisoner’s dilemma, developed by Fehr, Kirchsteiger, and Riedl (1993), and popularized in a series of papers by Ernst Fehr and co-authors. While the European studies typically feature a high degree of gift exchange, the few U.S. studies provide some conflicting results. We find that the degree of gift exchange is surprisingly sensitive to an appare...

The Generalized Intelligent Framework for Tutoring (GIFT) is an open-source, modular, service-oriented framework which provides tools, methods and services designed to augment third-party training applications for the purpose of creating intelligent and adaptive tutoring systems. In this paper we provide a high-level overview of GIFT from the technical perspective, and describe the key tasks re...

In this study, self-regulation was investigated in 7to 10-year-old children using three different measures: (1) parent and child report questionnaires measuring temperamental effortful control, (2) a conflict task assessing efficiency of executive attention, and (3) the mistaken gift paradigm assessing social smiling in response to an undesirable gift. Both efficiency in executive attention and...

The main idea of generalized intelligent tutoring system (ITS) development tools like Generalized Intelligent Framework for Tutoring (GIFT) is to provide authors with high-level standards and a readily reusable structure within different domains. Hence, adapting such a tool could be the best way to boost an underdeveloped tutor. In this paper we propose the design for a new GIFTbased tutor for ...

We consider a new type of asymmetric rendezvous search problem in which Agent II needs to give Agent I a ‘gift’ which can be in the form of information or material. The gift can either be transfered upon meeting, as in traditional rendezvous, or it can be dropped off by II at a location he passes, in the hope it will be found by I. The gift might be a water bottle for a traveller lost in the de...

We study the Lagos and Wright (2005) model of monetary exchange in the laboratory. With a finite population of sufficiently patient agents, this model has a unique monetary equilibrium and a continuum of non-monetary gift exchange equilibria, some of which Pareto dominate the monetary equilibrium. We find that subjects avoid the gift-exchange equilibria in favor of the monetary equilibrium. We ...

Choosing an appropriate gift is difficult because the purpose of gift giving is to arouse affection in the receiver, not the giver, and too many variables that influence the results. Utilizing 600 samples and a hybrid method combining the decision tree and K-nearest neighbor approaches, this study builds a DTKNN two–stepped recommendation system which achieves a precision rate higher than 80%. ...
