The visual indexing theory proposed by Zenon Pylyshyn predicts that visual attention mechanisms are employed when projecting mental images onto a visual scene. Recent eye-tracking have supported this hypothesis by showing that people tend to look at empty places, where requested information has been previously presented. However it remained unclear what(More)
Numerous behavioral and neuro-imaging studies have demonstrated that the motor system is activated when people are presented with manipulable objects. However it remains a matter of debate whether these results should be interpreted as evidence that certain conceptual processes employ motor programs. In order to address this issue, we conducted two(More)
A key insight from 50 years of neurophysiology is that some neurons in cortex respond to information in a highly selective manner. Why is this? We argue that selective representations support the coactivation of multiple "things" (e.g., words, objects, faces) in short-term memory, whereas nonselective codes are often unsuitable for this purpose. That is,(More)
Program slicing is a well known technique for program analysis with a variety of useful applications. This thesis investigates a new method for program slicing based on relational representation of program facts and algorithms. A core slicing algorithm is presented and it is shown that it can be applied to a broad range of problems. A number of generalized(More)
The representation-building and the ana-logical mapping processes run in parallel in the AMBR model and thus they can influence each other. This paper describes how the AMBR model could explain the re-representation of the target when the analogi-cal mapping forces it. The mechanisms are presented and a simulation is described which shows that depending on(More)
This paper describes an attempt to ground the meaning of relational concepts in the sensory motor dynamics resulting from our active interaction with the world. It is suggested that relations are encoded by executing or mentally simulating actions which are constrained by the environment and the specifics of our physical bodies. The virtues of the approach(More)

Decades of research have shown that emotions are an essential component of human intelligence. However there are few attempts to model the interplay of emotions and other cognitive processes. In this article, we investigate the integration of emotion in a hybrid cognitive architecture on analogy-making. Two computer simulations are conducted to explore the(More)
This paper presents a series of simulations performed with the AMBR model that demonstrate how deduction, induction, and analogy can emerge from the interaction of several simple mechanisms. First, a case of deductive reasoning is demonstrated when a problem is solved based on general knowledge. The system represents the target in different ways depending(More)
