 emotion | a subjective feeling that is mentally directed toward some object |
| common sense | In the ____________ __________ theory of emotion, a stimulus causes an emotion, which then leads to an arousal. |
| James | In _________'s theory of emotion, a stimulus leads to direct arousal, which is then interpreted as an emotion |
| Schachter, two-factor | According to ____________'s ________________ theory of emotion, in response to a stimulus, one must experience a physical arousal AND assign a cognitive label to the arousal in order to experience an emotion. |
| False | True or False: Cognitive labeling plays a role in determining emotions, but it is not very significant. |
| facial feedback hypothesis | According to this theory, facial expressions can cause, shape, and intensify emotions. This was demonstrated in Soussigan's "pencil study" in 2002. |
| microexpressions | facial expressions with a duration that is on the order of milliseconds. |
| physical arousal, cognitive label | According to Schacter's theory of emotion, there are two requirements for experiencing an emotion. What are these two requirements? 1) Experience ____________ ______________ in response to a stimulus. 2) Assign a ______________ _____________ to what was experienced. |
| True | True or False: Schacter provided experimental evidence for his theory of emotion by artificially providing physical arousal to his subjects (via epinephrine), and then manipulating the emotions they experienced by providing cues in the environment. |
| feeling, object | An emotion has two components. What are they? |
| affect | The feeling associated with emotion, independent of the object |
| mood | a free-floating emotional feeling, not directed at a specific object |
| amygdala | a cluster of nuclei in the temporal lobe under the cerebral cortex, that forms part of the limbic system; it is the brain's early warning system, and is essiential for unconscious emotional processes |
| subcortical, cortical | The amygdala receives sensory input via two routes: a very rapid ____________ route that analyzes incoming information even before it's processed by the cerebral cortex, and a somewhat slower _________ route that analyzes in more detail information that's processed by the cortex. |
| False | True or False: people with damage to the amygdala generally can still respond emotionally to stimuli . (Answer on pg 221) |
| prefrontal cortex | The foremost portion of the frontal lobe of the cerebral cortex; it is essential for the full conscious experience of emotions and the ability to act in deliberate, planned ways based on those feelings. |
| amygdala, somatosensory cortex | The prefrontal cortex receives input from the ____________ and from the _________________ ________. |
| right, left | The prefrontal cortex of the ______ hemisphere appears to be most involved in negative emotions, and that of the ______ hemisphere appears to be most involved in positive emotions. |
| motivation | the entire constellation of factors, some inside the organism and some outside, that cause an individual to behave in a particular way at a particular time |
| drive | an internal condition that orients an individual toward a specific category of goals and that can change over time in a reversible way; an aroused tension state |
| motivational state | another name for drive. |
| Drive Reduction Theory | According to this theory, a physiological need creates an aroused tension state (drive) that motivates an organism to carry out behaviors that satisfy the need, thereby reducing drives |

| Maslow | ___________'s theory of motivation argues that motivational needs are arranged hierarchically, from basic physiological needs to self-actualization |
| self-actualizing needs | The highest category of needs in Maslow's heirarchy; it involves the development of one's potential to its full extent. |
| educative | Drives that promote an organism to play, explore, or learn are called _______________ drives. |
| hypothalamus | The "appetite control center" of the brain |
| ventromedial, obese | The _______________ region of the hypothalamus is critical for appetite suppression. Damage to this area causes laboratory rats to become ___________. |
| lateral, lose | The _______________ region of the hypothalamus is critical for appetite stimulation. Damage to this area causes laboratory rats to _______ a lot of weight. |
| PYY | A hormone secreted by the cells in the large intestine. High levels of this hormone have been correlationally and experimentally associated with decreased appetite. |

| False | True or False: Additional leptin injections can benefit people who want to lose weight, regardless of whether they have the ability to produce leptin on their own. |
| True | True or False: If you have a friend whose weight has increased, your weight is more likely to increase as well. |
| acuate nucleus | the part of the hypothalamus that is the "master center" of appetite control and weight regulation; it is situated in the center of the lowest portion of the hypothalamus, very close to the pituitary gland. |

| BMI | a person's body weight in kilograms divided by the square of the person's height in meters. |
| overweight, obese | A BMI of 25 or more is considered _____________, and one of 30 or more is considered _____________. |
| True | True or False: Within Western cultures, the determination of who does or does not become obese depends very much on genes and relatively little on the specific home environment. (Answer on pg 193) |
| False | True or False: Within Western cultures, the determination of who does or does not become obese depends very much on genes and relatively little on the specific home environment, so body weight is little influenced by the environment. (Answer on pg 193) |
| True | True or False: The environmental conditions that promote obesity are fairly constant within Western cultures, so differences in weight have mostly to do with genetic differences in how individuals respond to those conditions. (Answer on pg 193). |

| dopamine | Drugs are addictive because they produce an immediate sense of euphoria, and they strongly activate the ___________-receiving neurons in the nucleus accumbens that are responsible for promoting reward-based learning. |
| central-state theory of drives | the theory that the most direct physiological bases for motivational states, or drives, lie in neural activity in the brain. According to this theory, different drives correspond to activity in different, localizable sets of neurons |
| central drive system | according to the central-state theory of drives, this is a set of neurons in the brain that, when active, most directly promotes a specific motivational state, or drive; this must 1)receive and integrate the various signals that can raise or lower the drive state, and 2)act on all the neural processes that would be involved in carrying out the motivated behavior |
