Acquired equivalence and generalized suppression in a virtual reality environment.
Acquired equivalence was investigated using a virtual reality conditioned suppression task administered in a first-person-shooter game. Two visual cues, A1 and B1, were followed by a tone (O1), and another two cues, A2 and B2, were followed by another tone (O2). During differential Pavlovian conditioning, A1 was paired with an instructed unconditioned stimulus (US) consisting of a flashing whit...
متن کاملFrozen with fear: Conditioned suppression in a virtual reality model of human anxiety.
Freezing-like topographies of behavior are elicited in conditioned suppression tasks whereby appetitive behavior is reduced by presentations of an aversively conditioned threat cue relative to a safety cue. Conditioned suppression of operant behavior by a Pavlovian threat cue is an established laboratory model of quantifying the response impairment seen in anxiety disorders. Little is known how...

متن کاملUsing virtual menus in a virtual environment
Virtual environment interfaces to computer programs in several diverse application areas are currently being developed. The users of virtual environments will require many different methods to interact with the environments and the objects in them. This paper reports on our use of virtual menus as a method of interacting with virtual environments. Several aspects of virtual environments make me...
متن کاملA confounding of conditioned suppression in passive avoidance: ECS effects
In the one-trial passive avoidance paradigm punishment of a highly probable response results in decreased rates and increased latencies of response. Presumably, Sa have learned to avoid the noxious stimulation by not responding. However, decreased response rates may be produced by an alternative procedure-conditioned suppression-where a freezing response conditioned to the situational cues comp...
