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 such as population size. Although of utmost importance, environmental effects on aggregation performance have not been studied systematically. In this paper, we study the effects of different environmental factors: size, texture and number of cues in a static setting, and moving cues in a dynamic setting using real robots. We used the aggregation time and size of the aggregate as the two metrics with which to measure aggregation performance. We performed real robot experiments with different population sizes and evaluated the performance of aggregation using the defined metrics. We also proposed a probabilistic aggregation model and predicted the aggregation performance accurately in most of the settings. The results of the experiments show that environmental conditions affect the aggregation performance considerably and have to be studied in depth.

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...
Power-Law Distribution of Long-Term Experimental Data in Swarm Robotics
Arvin, Farshad; Attar, Abdolrahman; Turgut, Ali Emre; Yue, Shigang (2015-06-02)
Bio-inspired aggregation is one of the most fundamental behaviours that has been studied in swarm robotic for more than two decades. Biology revealed that the environmental characteristics are very important factors in aggregation of social insects and other animals. In this paper, we study the effects of different environmental factors such as size and texture of aggregation cues using real robots. In addition, we propose a mathematical model to predict the behaviour of the aggregation during an experiment.
Implicit knowledge versus psychoacoustic similarity in priming of chords
Tekman, HG; Bharucha, JJ (American Psychological Association (APA), 1998-02-01)
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 ...
Bio-inspired artificial pheromone system for swarm robotics applications
Na, Seongin; Qiu, Yiping; Turgut, Ali Emre; Ulrich, Jiri; Krajnik, Tomas; Yue, Shigang; Lennox, Barry; Arvin, Farshad (SAGE Publications, 2020-06-03)
Pheromones are chemical substances released into the environment by an individual animal, which elicit stereotyped behaviours widely found across the animal kingdom. Inspired by the effective use of pheromones in social insects, pheromonal communication has been adopted to swarm robotics domain using diverse approaches such as alcohol, RFID tags and light. COS phi is one of the light-based artificial pheromone systems which can emulate realistic pheromones and environment properties through the system. This...
Efficacy of a problem-solving therapy for depression and suicide potential in adolescents and young adults
ESKİN, MEHMET; Ertekin, Kamil; Demir, Hadiye (Springer Science and Business Media LLC, 2008-04-01)
Short-term and structured cognitive behavioral problem-solving therapy (PST) is a developmentally relevant mode of action for the treatment of emotional problems in young people. This study aimed at testing the efficacy of a problem-solving therapy in treating depression and suicide potential in adolescents and young adults. A total of 46 self-referred high school and university students who were randomly assigned to a problem-solving therapy (n = 27) and a waiting list control (n = 19) conditions completed...
