In Seligman's hypothesis, the dogs do not try to escape because they expect that nothing they do will stop the shock. To change this expectation, experimenters physically picked up the dogs and moved their legs, replicating the actions the dogs would need to take in order to escape from the electrified grid.
Seligman and colleagues accidentally discovered that the experimental conditioning protocol they used with dogs led to behaviors which were unexpected, in that under the experimental conditions, the recently conditioned dogs did not respond to opportunities to learn to escape from an unpleasant situation ('electric shocks of moderate intensity ...
According to Martin Seligman, this is a result of our evolutionary history. The theory states that organisms which learned to fear environmental threats faster had a survival and reproductive advantage. Consequently, the innate predisposition to fear these threats became an adaptive human trait. [3]
Dogs are perhaps best known for being loving and loyal, but they also have a bevy of lesser-known (and quite fascinating) traits. Here are 10 incredible scientific discoveries about them: Number ...
The first two dogs quickly recovered from the experience, but the third dog suffered chronic symptoms of clinical depression as a result of this perceived helplessness. A further series of experiments showed that, similar to humans, under conditions of long-term intense psychological stress, around one third of dogs do not develop learned ...
Conditioned taste aversion occurs when an animal acquires an aversion to the taste of a food that was paired with aversive stimuli. The effect explains that the aversion develops more strongly for stimuli that cause nausea than other stimuli.
A drawing by Konrad Lorenz showing facial expressions of a dog - a communication behavior. X-axis is aggression, y-axis is fear. Dog behavior is the internally coordinated responses of individuals or groups of domestic dogs to internal and external stimuli. [1] It has been shaped by millennia of contact with humans and their lifestyles.
[31]: 282–5 Martin Seligman and his colleagues discovered that they could condition in dogs a state of "learned helplessness", which was not predicted by the behaviorist approach to psychology. [ 109 ] [ 110 ] Edward C. Tolman advanced a hybrid "cognitive behavioral" model, most notably with his 1948 publication discussing the cognitive maps ...
