Aggressive behavior and extinction-induced response-rate increase

Carbachol-induced agonistic behavior in cats: aggressive or defensive response.

The effects of intrahypothalamic carbachol microinjections were investigated in unprovoked cats. The carbachol evoked mydriasis, attention, vocalization, and piloerection, i.e. features of a typical defense were usually concomitant in evoked response, while the clear-cut aggressive or escape patterns appeared only once. No basic differences were observed in the set of manifestations induced by ...

Of Behavior Extinction - Induced Aggression

Pigeons were conditioned to peck a response key under a procedure that alternated periods of food reinforcement with periods of extinction. The pigeons attacked a nearby pigeon at the onset of extinction. Some also attacked a stuffed model of a pigeon. The duration of attack was an inverse function of the time since the last food reinforcement and a direct function of the number of reinforcemen...

Ataractic suppression of isolation-induced aggressive behavior.

Resurgence of behavior during extinction depends on previous rate of response.

In two experiments, food-deprived rat subjects leverpressed for food in three successive training phases. In the first phase of both experiments, rats were exposed to a multiple schedule, one component of which produced a high rate of response, and the other of which produced a lower rate of response (multiple random ratio [RR], random interval [RI] in Experiment 1, and multiple differential re...

Sleep Problems and Aggressive Behavior in Children with ADHD

Objective: Aggression is a disruptive behavior that limits children’s ability for a better adjustment. As commonly reported, sleep problems is associated with the presentation of aggression in ADHD children. In this study, we aimed to investigate the association between sleep problems and aggressive behavior in children with ADHD.  Methods: The study method is correlational and cross-section...
