A chord-priming paradigm was used to test predictions of a neural net model (MUSACT). The model makes a nonintuitive prediction: Following a prime chord, expectations for the target chord are based on psychoacoustic similarity al short stimulus onset asynchronies (SOAs) but on implicit knowledge of conventional relationships at longer SOAs. In a critical rest, 2 targets were selected for each prime. One was more psychoacoustically similar to the prime, and the other was more closely related on the basis of convention. With an SOP, of 50 ms, priming favored the psychoacoustically similar target; with SOAs of 500 ms and longer, the effect reversed, and priming favored conventional relatedness. The results underscore the limitations of models or harmony based on psychoacoustic factors alone. These studies demonstrate how neural net learning models that are appropriately constrained can be subject to strong empirical verification.

Traversability: A Case Study for Learning and Perceiving Affordances in Robots
Ugur, Emre; Şahin, Erol (SAGE Publications, 2010-06-01)
The concept of affordances, introduced in psychology by J. J. Gibson, has recently attracted interest in the development of cognitive systems in autonomous robotics. In earlier work (Sahin, Cakmak, Dogar, Ugur, & Ucoluk), we reviewed the uses of this concept in different fields and proposed a formalism to use affordances at different levels of robot control. In this article, we first review studies in ecological psychology on the learning and perception of traversability in organisms and describe how the ex...
Generation of cyclic/toroidal chaos by Hopfield neural networks
Akhmet, Marat (Elsevier BV, 2014-12-05)
We discuss the appearance of cyclic and toroidal chaos in Hopfield neural networks. The theoretical results may strongly relate to investigations of brain activities performed by neurobiologists. As new phenomena, extension of chaos by entrainment of several limit cycles as well as the attraction of cyclic chaos by an equilibrium are discussed. Appropriate simulations that support the theoretical results are depicted. Stabilization of tori in a chaotic attractor is realized not only for neural networks, but...
Prospective duration judgments: The role of temporality and executive demands of concurrent tasks
Duzcu, Haul; Hohenberger, Annette Edeltraud (Elsevier BV, 2014-03-01)
It is known that concurrent non-temporal tasks shorten reproduced temporal durations in prospective duration judgments. Two experiments were carried out, one comparing a concurrent temporal task to a minimally demanding concurrent task (Experiment 1) and one comparing an executive concurrent (Simon) task with a less demanding non-executive concurrent task (Experiment 2). An effect of the concurrent task type on temporal reproductions was found. Furthermore, a duration length effect was found, where longer d...
Investigation of cue-based aggregation in static and dynamic environments with a mobile robot swarm
Arvin, Farshad; Turgut, Ali Emre; Krajnik, Tomas; Yue, Shigang (SAGE Publications, 2016-04-01)
Aggregation is one of the most fundamental behaviors and has been studied in swarm robotic researches for more than two decades. Studies in biology have revealed that the environment is a preeminent factor, especially in cue-based aggregation. This can be defined as aggregation at a particular location which is a heat or a light source acting as a cue indicating an optimal zone. In swarm robotics, studies on cue-based aggregation mainly focused on different methods of aggregation and different parameters su...
To afford or not to afford: A new formalization of affordances toward affordance-based robot control
Şahin, Erol; Dogar, Mehmet R.; UĞUR, Emre; Üçoluk, Göktürk (SAGE Publications, 2007-01-01)
The concept of affordances was introduced by J. J. Gibson to explain how inherent "values" and "meanings" of things in the environment can be directly perceived and how this information can be linked to the action possibilities offered to the organism by the environment. Although introduced in psychology, the concept influenced studies in other fields ranging from human-computer interaction to autonomous robotics. In this article, we first introduce the concept of affordances as conceived by J. J. Gibson an...
