Motivation, Emotion, and Personality - AP Psychology

Type A personalities are characterized as being very competitive, goal-driven, and impatient. Additionally, Type A personalities are most likely to exhibit high levels of anger, hostility, and cynicism. While all humans will, at some point, experience lethargy, sadness, happiness, and depression these are, specifically, not characteristic of a Type A personality.

The Cannon-Bard theory states that the brain cannot rely on bodily responses to know which emotions it is experiencing. This is supported by the observation that a racing heart can indicate excitement, fear, or anger.

Edward Thorndike was a prominent American psychologist who proposed the law of effect, which posits that responses that are followed with a positive consequence are more likely to be repeated, as opposed to responses that are not reinforced. B.F. Skinner's theory of operant conditioning is primarily based on the law of effect.

Those with a fantasy-prone personality spend much time daydreaming, thus utilizing their vivid imagination. They are often able to recall their fantasies with near perfect accuracy.

Alfred Alder focused greatly on the biology behind psychology in his early career. As a child, Alder was frequently physically weak and ill. He eventually recovered and went on to become a successful psychologist. The theory that a person’s psyche can become weak due to their organs being weak was influenced by Alder’s childhood experiences.

Catharsis, when being used in the context of psychoanalysis, most often refers to a release of pent up, repressed, or strong emotions. These are often negative in nature, such as sadness or anger. In Western societies, it is most often aggression, due to the fact that aggression is a socially unacceptable emotion to display in public.

Positive psychology is a growing field of psychological research that seeks to grow the empirical data on optimal human functioning and positive emotions (e.g., longitudinal happiness)

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.
