Motivation and Emotion - AP Psychology

While primary drives are directly related to basic survival and reproduction, secondary drives are related to social factors. Money is not directly related to basic survival, but it can aid in quelling primary drives (for example, using money to buy food to reduce hunger).

The id operates on the pleasure principle and seeks immediate gratification. The id satisfies drives, developed from physiological needs such as hunger, thirst, sexual drives, and more. The id, unlike the ego or superego, contains no morality or judgment of value. Rather, it seeks immediate pleasure or avoidance of pain, and disregards long-term consequences and benefits.

Proposed by Abraham Maslow, the hierarchy of needs theory states that the most important physiological needs must be met before other, less urgent needs are met. These essential needs consist of oxygen, food, water, and shelter. After physiological needs are met, one will seek to fulfill the need for safety and security (personal, physical, and financial), belongingness and love (friendship, intimacy, and family), then self esteem (earned respect), self actualization (reaching one’s highest potential), and then self transcendence (finding a greater, spiritual purpose in life). According to Maslow, very few people reach a level of self transcendence.

The amygdala is a key brain structure in the limbic system. Those who experience brain damage in this area have difficulty developing conditioned fear responses.

Drive reduction theory is based on the idea that human behavior is motivated by various drives. This behavior is undertaken in hopes of reducing the state of tension these drives create. The most basic of examples would be that when people are hungry they experience the distress of hunger and are motivated to look for food. A more nuanced example might be humans' drives to connect with romantic partners. If humans seek connection and don't find it with one partner, they may look for it in another person.

Extrinsic motivation is a pervasive force behind many of our daily behaviors. Most people don't go to work because it's intrinsically pleasurable, but because they need something. In essence, extrinsic is when someone does something for something else. We go to school to avoid punishment and get approval from our teachers, parents, and peers. We work to get money to pay the bills to avoid being broke and to make our families happy and comfortable.

The reverse is doing something for its intrinsic pleasure, known as intrinsic motivation. For instance we may enjoy knowing more about the world for the pleasure it gives us, not what we have to gain from it.

Emotions are a product of evolution designed to signal when humans need or want something or when a certain need or want has been met. Emotions are universal, as they can be observed cross-culturally, though the degree of expression of emotion may vary in different cultures.

Gherlin is secreted by an empty stomach and tells the brain to switch hunger on. Leptin is secreted by fat cells and tells the brain to switch hunger off. Serotonin is a neurotransmitter associated with feelings of well-being.

Primary drives refer to things a person needs to survive, like thirst and hunger. Secondary drives are determined by social factors, money, pride, and fame are all great examples of secondary, not primary, drives.

The Yerkes-Dodson law is a curve known for its bell shape, relating its independent variable (i.e. arousal) to its dependent variable (i.e. performance). This graph shows that performance peaks at moderate levels of arousal, as high levels of arousal result in stress while low levels of arousal result in boredom.

Mood-congruent memory is the tendency to recall experiences that are consistent with one's good or bad mood. Thus, if the subject is upset, he is more likely to recall negative memories during which he experienced a similar emotional state.

There are seven "basic" emotions that have been observed in nearly every culture on earth, and are recognizable between cultures even if those cultures have never interacted previously. These fundamental emotions are: joy, sadness, anger, fear, surpise, contempt, and disgust. Confusion is not one of the universal expressions.

The limbic system deals with emotion and memory. The corpus callosum connects the left and right hemispheres of the brain.

Richard Lazarus's theory of appraisal, which departs from a physiological explanation for emotion, posits that emotions are a result of people's subjective experience of an event. This theory is exemplified by the old tale of many different people looking at an elephant: each of these people will focus on different aspects of this elephant, like its ears, trunk, feet, etc. Likewise, someone's emotional experience of a busy road depends on his or her interpretation. Many might fear the busy road. Others accept it and feel content. Others focus on the sun outside and feel joy.

Emotions play a major role in signaling whether or not needs are being met. For instance, if we feel sad, this could be a signal that emotional, or even physical, needs are not being met. If we feel happy, this is a sign we've done something right that has fulfilled one need or another. There are other emotions, however, that are more complex. Things like surprise can be purely reactionary and unrelated to our needs, where our body is preparing itself to ascertain more information about the event (I.E. widening of the eyes to see more, opening the mouth for more respiration).

The statement used in the example is an example of a statement that, while discussing a psychological topic, is too general in nature to accurately reflect a valid psychological principle. Also, the statement offers no proof of its assertion, and does not mention any research in support of its assertion. Even if a statement seems intuitively accurate, in order for it to be a valid statement it must be specific, and supported by evidence.

The facial-feedback hypothesis is the idea that using the muscles involved in a certain emotion will make you feel that emotion. By expressing emotions with one's face, that emotion is intensified by the feedback loop created by this process.

Paul Ekman was primarily responsible for identifying many of the possible emotions of the human species and how these emotions were expressed facially. He argued that emotions were universal, though culture produced varying factors on to what extent they could be expressed and what situations/ideas would evoke which emotions. He came to this conclusion by studying emotions across cultures.

A primary drive is a drive that is completely unlearned, something that any human will inherit regardless of their socialization, upbringing, or background. Primary drives are concerned with survival and reproduction. These drives for humans are hunger, sex, thirst, sleep, and bathroom needs. All of these ensure the health, maintenance, and reproduction of the human species.
