BACKGROUND Media depictions of violence, although often claimed to induce viewer aggression, have not been shown to affect the cortical networks that regulate behavior. METHODOLOGY/PRINCIPAL FINDINGS Using functional magnetic resonance imaging (fMRI), we found that repeated exposure to violent media, but not to other equally arousing media, led to both diminished response in right lateral orb...

Multiagent schema-based reactive robotic systems are complemented with the addition of a new behavior controlled by a human operator. This enables the whole society to be aaected as a group rather than forcing the operator to control each agent individually. The operator is viewed by the reactive control system as another behavior exerting his/her innuence on the society as a whole. The operato...

Behavior may be controlled by reactive systems. In a reactive system the motor output is exclusively driven by actual sensory input. An alternative solution to control behavior is given by “cognitive” systems capable of planning ahead. To this end the system has to be equipped with some kind of internal world model. A sensible basis of an internal world model might be a model of the system’s ow...

This study employs uses and gratifications (U&G) theory to examine the motives and face-to-face bullying experiences of cyberbullies and how those motives and experiences influence their Internet bullying. An online survey and multiple regressions were employed to test the hypotheses. The results revealed that a cyberbully with more victim experience in faceto-face bullying will be more likely ...

This paper presents a method for fuzzy logic-based 'perception-action' behavior control of a mobile robot in uncertain environments. A key problem in 'perception-action' behavior control is to coordinate and integrate more reactive behaviors when the mobile robot executes tasks in complex environments. The main idea of the paper is to formulate 'perception-action' behaviors and to coordinate th...

Mammals bootstrap their cognitive structures through embodied interaction with the world. This raises the question: how the reactive control of initial behavior is recurrently coupled to the high-level symbolic representations they give rise to? We investigate this question in the framework of the "Distributed Adaptive Control" (DAC) cognitive architecture, where we study top-down and bottomup ...

AI in computer games has been highlighted in recent, but manual designing costs a great deal. An evolutionary algorithm has developed strategies to play games without using features that would commonly require the knowledge of developers. Since the real-time reactive selection of behaviors for NPCs is required for better playing, a reactive behavior system consisting neural networks is presente...

The purpose of this study was to extend the current literature on forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of participants’ cognitions and beliefs about aggressive behavior. Participants included an ethnically diverse group of emerging adults (N = 165; M = 19.05 years; SD = 1.55) and completed a battery of selfreport instruments. Gender differences for ...

We discuss six labs that present two contrasting approaches to AI robotics. The first four labs present the traditional, representation-based approach to designing behavior control algorithms for autonomous robots. Robots use an internal representation of the world plus a planning algorithm to guide behavior. The second two labs present a behaviorbased or reactive approach to managing robot beh...
