in the dog, ears back, back down, hair down, and tail down signals what
submission
in rats, boxing is
- a defensive mechanism and directed at attacking conspecifics - defensive
according to the cannon-bard theory, emotional experience and emotional expression
- are parallel processing - have no direct casual relation - are independently triggered by the same emotional stimuli
darwin believed that
- expressions of emotion evolve from behaviors that indicate what an animal is likely to do next. - expressions of emotion evolve in ways that enhance their communicative function and that their original function may be lost - opposite messages are often signaled by opposite movements and postures
overall, research has found the effects of testosterone on the aggressive behavior of humans to be inconsistent - the text suggests that this inconsistency may be attributable to the fact that
- hormones may have less effect on human aggression than they do on aggression in other species - the tests hat have been used to study testosterone and aggression in humans are markedly different from those used in other species - testosterone can be synthesized and act locally in particular brain structures but studies of testosterone and human aggression have been based on the general blood levels of testosterone
the dominant male rat of a colony
- is the alpha - usually moves sideways toward another male intruder - directs lateral attacks at male intruders - durects bites at the back of a male intruder
gastric ulcers
- lesions to the lining of the stomach and duodenum - more common in people living in stressful situations - have been produced in experimental animals by exposure to stress
the fact that social aggression in many mammalian species occurs more frequently between males than females is often attributed to
- organizational effects of testosterone - activational effects of testosterone
the first major book on the biopsychology of emotions
- published in 1872 - was the expression of emotions in man and animals - introduced darwin's theory of the evolution of emotional expression
adrenocorticotropic hormone
- released by the anterior pituitary - activates the adrenal cortex - increases circulating levels of glucocorticoids
on the basis of existing evidence, the following conclusion about ANS emotional specificity is warranted:
- the ANS does not respond in the same way to all emotional stimuli - there is not enough. evidence to conclude that there is a different pattern of ANS activity associated with each emotional state
the defensive and aggressive behaviors of rats has been assigned to various categories on the basis of
- their topography - situations in which they occur - their apparent function
which of the following is a major finding of cognitive neuroscience research on emotion
- there is usually activity in sensory and motor cortex when a person experiences emotion - similar patterns of brain activity occur when a person experience an emotion or empathizes with someone experiencing the same emotion
the emotional experiences of patients with broken necks
-indicate the somatic and autonomic feedback from the body is not necessary for the experience of emotion - are inconsistent with the james-lange theory

different
the true smile, which involves the orbicularis oculi, has been termed the
duchenne smile

experience of emotion is produced by the brain's perception of th ebody's reactions to emotional stimuli
the belief that putting on a happy face makes one feel happier is an example of the
facial feedback hypothesis
the theory that facial expressions can influence emotional experience is called the
facial feedback hypothesis
the most commonly employed physiological measure of stress in the level of circulating
glucocorticoids
because even innocent people undergoing a lie-detector test are likely to be aroused by questions about their guilt or innocence, the
guilty-knowledge technique should be employed when possible
lymphocytes are
- specialized white blood cells - produced in the bone marrow - stored in the lymphatic system
in order to employ the guilty-knowledge technique, the polygrapher needs to
have a piece of information about the crime that is known by the guilty party but not by any of the other suspects
how many primary facial expressions are there
6
lesions to which structure specifically block the conditioning of fear to a contex
hippocampus
Papez believed that emotional states were expressed through the action of the other limbic structures on the
hypothalamus
bard's 1929 research on sham rage led him to conclude that the
hypothalamus plays a critical role in the expression of aggression
the amygdala is thought to activate the appropriate sympathetic and behavioral responses to threat via the __________ and the appropriate behavioral responses to threat via the
hypothalamus, PAG

increase the ability to deal effectively with the stressor
the duchenne smile
involves the orbicularis oculi
the first major physiological theory of emotions was independently proposed in 1884 by james and
lange
evidence suggests that only one part of the amygdala plays a major role in fear conditioning --
lateral nucleus
polygraphy is commonly referred to as
lie detection
papez attributed emotion to activity in what became known as the
limbic system
what is not a primary emotional expression
lust
in most mammalian species social aggression usually occurs between
male conspecifics
most patients with gastric ulcers display signs of H. pylori infection, however, to put this observation in perspective, it is important to understand that

modern neuropsychological and cognitive neuroscientific research has emphasized the roles of two brain structures in emotion: the
medial prefrontal cortex and amygdala
the true expressions that momentarily break through false expressions are called
microexpression
because it is usually difficult to determine for certain whether a person who has been accused of breaking the law is innocent or guilty, many studies of lie detection us the
mock-crime procedure
