Chapter 17 - Biopsychology of Emotion, Stress & Health Flashcards
James-Lange theory
the theory that emotion-inducing sensory stimuli are received and interpreted by the cortex, which triggers changes in the visceral organs via the autonomic nervous system and in the skeletal muscles via the somatic nervous system. Then the autonomic and somatic responses trigger the experience of emotion in the brain
Cannon-Bard theory
the theory that emotional experience and emotional expression are parallel processes that have no direct causal relation
sham rage
poorly directed aggressive responses of decorticate animals
limbic system
a collection of interconnected nuclei and tracts that ring the thalamus
Klüver-Bucy syndrome
anterior temporal lobes had been re- moved;
> following behaviors: the con- sumption of almost anything that is edible, increased sexual activity often directed at inappropriate objects, a tendency to repeat- edly investigate familiar objects, a tendency to investigate objects with the mouth, and a lack of fear
Polygraphy
method of interrogation that employs ANS indexes of emotion to infer the truth- fulness of a person’s responses
control-question technique
the physiological response to the target question (e.g., “Did you steal that purse?”) is compared with the physiological responses to control questions whose answers are known
guilty-knowledge technique
a lie-detection method in which the polygraphed records autonomic nervous system responses to a list of control and crime-related information known only to the guilty person and the examiner; also known as the concealed information test
facial feedback hypothesis
our facial expressions influence our emotional experience
Duchenne smile
genuine smile
Fear
emotional reaction to threat; it is the motivating force for defensive behaviors
Defensive behaviors
behaviors whose pri- mary function is to protect the organism from threat or harm
aggressive behaviors
behaviors whose primary function is to threaten or harm
target-site concept
the idea that the aggressive and defensive behaviors of an ani- mal are often designed to attack specific sites on the body of another animal while protecting specific sites on its own
Fear conditioning
the establishment of fear in response to a previously neutral stimulus (the conditional stimulus) by presenting it, usually several times, before the delivery of an aversive stimulus (the unconditional stimulus)
