Motivation
The process that initiates, guides, and maintains goal-oriented behaviors
Instinct Theory (Evolutionary Perspective)
Our behavior is motivated by our inborn automated/primal behaviors
Drive Reduction Theory
Our behavior is motivated by our biological need to reduce internal physiological drives and maintain homeostasis; pushed by primary (physiological) and secondary (interest) drives, pulled by incentives
Homeostasis
A tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry around a particular level
Optimal Arousal Theory
Our behavior is motivated by seeking an optimum level of arousal or stimulation (levels may vary)
Yerkes-Dodson Law
The psychological principle stating that performance is best under conditions of moderate arousal rather than either low or high arousal
Incentive Theory
Motivation results from a positive or negative environmental stimuli that pull the organism in certain directions, such as the pursuit of rewards or the avoidance of punishments
Cognitive Theory
Motivation is affected by attributions on behavior, or how we interpret and think about our own or others’ actions
Maslow’s Hierarchy of Needs
Our behavior is motivated by various levels of needs in a five-tier pyramid, beginning with lower-level physiological and safety needs that must first be satisfied, then goes to higher-level social, self-esteem, actualization, and meaning needs
Maslow’s Self Transcendence Needs (6)
Need to find meaning and identity beyond the self
Maslow’s Self Actualization Needs (5)
Need to live up to one’s fullest and unique potential; need to pursue meaningful goals and personal growth
Maslow’s Esteem Needs (4)
Need for self-esteem, achievement, competence, independence, recognition, and respect from others
Maslow’s Belongingness and Love Needs (3)
Need social connections and emotional bonds; to love and be loved; to belong and be accepted; to avoid loneliness and alienation
Maslow’s Safety Needs (2)
Need to feel that the world is organized and predictable; need to feel safe, secure, stable, protected, and assured
Maslow’s Physiological Needs (1)
Need to satisfy basic biological requirements, such as air, water, food, shelter, and sleep
Intrinsic Motivators
Internal rewards that drive behavior, such as enjoyment, satisfaction, fulfillment, interest
Extrinsic Motivators
External rewards that drive behavior, such as praise, grades, money, or other tangible rewards/consequences
Biological Basis of Hunger
Hunger does not come from our stomach, it comes from the hypothalamus
Lateral Hypothalamus
The sides of the hypothalamus, which brings on hunger (stimulation = hunger; lesion = never feel hungry again)
Ventromedial Hypothalamus
The lower-mid hypothalamus, which depresses hunger (stimulation = feel full; lesion = never feel full again)
Set Point Theory
The point at which an individual’s “weight thermostat” is supposedly set; the hypothalamus maintains a stable weight; body falls below weight = increase in hunger and lowered metabolic rate to restore lost weight
Achievement Motivation
A desire for significant accomplishment; for mastery of things, people, or ideas; for rapidly attaining a high standard (includes intrinsic and extrinsic motivation)
Body Mass Index (BMI)
A numerical value derived from an individual’s weight and height, but does not account for muscle mass and overall health
Basal Metabolic Rate (BMR)
The amount of energy an individual’s body needs to maintain basic physiological functions, which can determine how many calories should be consumed daily
Fat Cells
Cells that store energy in the form of fat; cells may shrink, but numbers will never decrease (obese = numerous & larger; lose weight = numerous & smaller)
Biofeedback
Technique of gaining greater awareness of many physiological functions of one’s body by using electronics or other instruments to help monitor health (heart rate, breathing, etc)
Taste Aversion (Garcia Effect)
A learned avoidance of a specific taste or flavor due to its association with a negative experience
Glucose
The form of sugar that circulates in the blood and provides the major source of energy for body tissues (low level = hungry)
Anorexia Nervosa
An eating disorder in which a person (usually an adolescent female) diets and starves themselves below 85% of their normal body weight; often have a distorted body image and a relentless pursuit of thinness
Bulimia Nervosa
An eating disorder characterized by recurrent episodes of binging (eating large amounts of food) followed by purging (getting rid of the food) in fear of gaining weight
Binging
The consumption of a large amount of food within a short period, often accompanied by a sense of loss of control
Purging
The compensation for the consumption of large amounts of food, often in them form of self-induced vomiting, excessive exercise, or the use of laxatives
Body Chemistry
The complex biochemical processes within the body that regulate physiological functions, including orexin, ghrelin, insulin, leptin, and PYY
Orexin
A neuropeptide produced in the hypothalamus that regulates alertness and increases hunger
Ghrelin
A hormone produced in the stomach that regulates appetite and increases hunger
Insulin
A hormone produced by the pancreas that lowers blood sugar levels and increases hunger
Leptin
A hormone produced by fat cells that regulate energy balance and decreases hunger
PYY (Peptide YY)
A hormone produced by in the digestive tract that regulates food intake and decreases hunger
Binge Eating Disorder (Obesity)
Significant binge-eating episodes (followed by distress, disgust, or guilt) without the compensatory purging in bulimia nervosa, which causes health issues
Pica
A disorder characterized by abnormal consumption of non-nutritive, non-food substances
Avoidant/Restrictive Food Intake Disorder (ARFID)
A feeding and eating disorder characterized by persistent avoidance or restriction of food intake, often associated with sensory sensitivity, or lack of interest in eating
Other Specified Feeding or Eating Disorder (OSFED)
A category within eating disorders that includes individuals who have disordered eating patterns but do not meet the specific criteria for most eating disorders
Orthorexia
An eating disorder characterized by an obsessive focus on consuming only healthy or “pure” foods
Night Eating Syndrome (NES)
An eating disorder characterized by a pattern of consuming a significant portion of daily food intake during the nighttime, often waking up to eat
Unit Bias
A cognitive tendency for individuals to consume a specific portion of food, often defined by social norms, without regard for their actual hunger or nutritional needs
Flow
A completely involved, focused state of consciousness, with diminished awareness of self and time, resulting from optimal engagement of one’s skills
Industrial-Organizational (I/O) Psychology
A branch of psychology that focuses on the application of psychological concepts and methods to optimizing human behavior in workplaces
