A study reveals that the brain areas that respond when fear is learned through personal experience are al-so triggered when we see someone else in distress. In the study, participants watched a short video of a person conditioned to fear a so-called neutral stimulus-something people normally ...
In operant conditioning, when a stimulus is added to the environment, it is: a. More likely to occur b. Negative c. Positive d. Less likely to occur Operant Conditioning: Operant conditioning is one of the two major behavioral f...
From an evolutionary perspective, it is understandable that there is the need for prompt recognition of us/them with respect to gender. We know that a fear emotional reaction is more likely to be conditioned by an angry male face than by a female face, and by an adult face than by a ch...
presented on the response key (LoLordo, 1971; Boakes et al., 1975), smaller when the stimuli are separated from the response key (Westbrook, 1973), and is absent in conditions in which key pecking is replaced by foot-pressing a treadle (Westbrook, 1973; Green and Holt, 2003; LoLordo ...
In classical conditioning, acquisition refers towhen the previously neutral stimulus becomes associated with the unconditioned stimulus and comes to evoke a response when presented. At this point, the unconditioned stimulus becomes known as the conditioned stimulus. ...
Negative reinforcement is: a. a pleasant stimulus that increases the likelihood of the response occurring again. b. an unpleasant stimulus that increases the likelihood of the response occurring again. c. an unpleasant stimulus that decreases the...
More limited easy-to-hard transfer of this kind has been found when the conditioned stimulus mo- dality was also changed as the ISI lengthened (Kehoe & Holt, 1984). Finally, conditioning an aversion to one taste using a short delay can facilitate subsequent acquisition of long-delay aversion...

One emphasizes the ...
Upon the detection of imminent peril, pea aphids (Acyrthosiphon pisum) often drop off their host plant. Dropping in response to insect enemies is intermittent in nature, but when a mammalian herbivore feeds on their host plant, a large mixed-age group of
