Unit 7: Motivation, Emotion, and Personality Flashcards
Motivation
a need or desire that influences and directs behavior
Nature vs. Nurture in motivation
the “bodily push” (nature) combined with our personal experience (nurture) creates motivation
Instinct
a complex behavior that is rigidly patterned throughout a species and is unlearned
- humans are not primarily motivated by instinct; we have basic ones but more of our motivations are driven by psysiological needs and psychological wants
Instinct theory
theory that our instincts act as a source of motivation; inborn impulses are our motivation to action
Imprinting
the process by which certain animals form strong attachments during early life
Drive reduction theory
the idea that a physiological need creates an aroused state (a drive) that motivates an organism to satisfy the need
- drive reduction is the way our bodies strive for homeostasis, a tendency to maintain a balanced or constant internal state
homeostasis –> need –> drive –> drive reduction
incentives
a positive or negative environmental stimulus that motivates behavior
arousal theory
some motivated behaviors increase arousal (**think adrenaline junkies)
sometimes uncertainty brings excitement, amplifying motivation
Yerkes-Dodson Law
the principle that performance increases with arousal only up to a point, beyond which performance decreases (this point is different for different people)
- simpler tasks are performed best when arousal levels are relatively moderate/high whereas complex tasks are best performed when arousal levels are low
Maslow’s hierarchy of needs
Beginning at the base with physiological needs that must first be satisfied before higher-level safety needs and then psychological needs become active
How do glucose levels affect hunger?
If your blood glucose level drops, you won’t consciously feel the lower blood sugar. Your brain, which is automatically monitoring your blood chemistry and your body’s internal state, will trigger hunger.
Role of the Hypothalamus in hunger
Blood vessels supply the hypothalamus, enabling it to respond to our current blood chemistry/incoming neural info about the body’s state
Ghrelin
Hormone secreted by an empty stomach; sends “i’m hungry” signals to the brain
“set point” (in terms of weight)
The point at which your “weight thermostat” may be set. When your body falls below this weight, increased hunger and lowered metabolic rate may combine to restore lost weight.
- does not really exist; sustained changes in our body weight can alter one’s set point and psychological factors sometimes also drive our feelings of hunger
Testosterone
The most important male sex hormone. both males and females have it, but the additional testosterone in males stimulates the growth of the make sex organs during the fetal period and the development of the male sex characteristics during puberty
Oestrogen
sex hormones that contribute to female sex characteristics and are secreted in greater amounts by females than in males - oestrogen peaks during ovulation
Testosterone
The most important male sex hormone. Both males and females have it, but the additional testosterone in males stimulates the growth of the male sex organs during the fetal period and the development of the male sex characteristics during puberty
Affiliation need
the need to build relationships and be part of a group
Ostracism
deliberate social exclusion of groups or individuals
Narcissism
excessive self-love and self-absorbtion
Achievement motivation
a desire for significant accomplishment, mastery of skills or ideas, control, and for attaining a high standard
- those with high achievement motivation tend to achieve more with their persistence and eagerness for challenge
Emotion vs the autonomic nervous system
in a crisis the sympathetic division of your ANS mobilizes your body for action by directing your adrenal glands to release the stress hormone epinephrine and norepinephrine to prepare you for survival. When crisis has passed, the parasympathetic division works to gradually calm you down as stress hormones slowly leave the bloodstream
Common sense theory (theories of emotion)
Stimulus > Emotion > Arousal
- some sort of external stimulus will elicit an emotion response causing arousal
James-Lange theory (theories of emotion)
Stimulus > Arousal > Emotion
- an external stimulus causes an arousal, leaving you emotional
Cannon-Bard theory (theories of emotion)
Stimulus = Emotion + Arousal
- an external stimulus causes fear and a physical response at the same time
Schachter Singer “2 factor” theory (theories of emotion)
Stimulus > Arousal + cognitive label > Emotion
- an external stimulus elicits a psychological response and at the same time an internal analysis (or cognitive label), before emotion
Lazarus theory (theories of emotion)
Stimulus > Cognitive label > Emotion + arousal
- your brain analyses a situation and as a result produces an emotional and physical response
Zajonc and LeDoux theory (theories of emotion)
Stimulus > Thalamus > Amygdala > Fear
- instant emotional response; cognition is not always immediately involved
** think jumpscare
How do we communicate nonverbally?
Expressive behavior - body language and facial expressions
Difference between real and fake emotion
Hard-to-control face muscles are often signifiers of real emotion from fake
** activated under-eye muscles when expressing happiness
Most people cannot detect the minute differences between liars and truth tellars
Ekman’s research on emotional detection accuracy
Suggests that humans can detect falsity in feigned emotion; basic emotions are innate and shared by everyone, enough that we can accurately decipher them
Darwin’s ideas on historical expression of emotion
in prehistoric times, as means of survival our ancestors communicated in facial expression before verbal communication, and still we have retained some of those tendencies
