Unit 8 Elaina & Unit 9 & 10 Rachel- Test 3 Flashcards
Define Developmental Psychology:
how we grow, develop, and change throughout the lifespan.
Describe Chromosome:
Rod-shaped structures, found in the nuclei of body cells, that contain all the genes and carry all the hereditary information.
- 23 pairs
- 22 pairs are called autosomes
- 23rd pair is called sex chromosomes
Define DNA:
Genes are segments of this located on each of the chromosomes
Define gene:
Within the chromosomes, the segments of DNA that are the basic units for the transmission of hereditary traits
Describe dominant trait:
A gene that is expressed in the individual
Describe recessive trait:
A gene that will not be expressed if paired with a dominant gene, but will be expressed if paired with another recessive gene
Describe sex chromosome:
- It carries the genes that determine one’s sex and primary and secondary sex characteristics
- Sperm cells and the mature egg cells each have 23 single chromosomes.
- At conception, the sperm adds its 23 single chromosome to the 23 of the egg. This union forms a single cell called a zygote , which has the full 46 chromosomes (23 pairs), which in turn contains about 30,000 genes-the genetic material needed to make a human being.
What are the three stages of prenatal development?
- Period of the zygote
- Period of the embryo
- Period of the fetus
Describe Stage 1- Period of the zygote
Time after Conception: 1 to 2 weeks
Major Activities of the Stage: zygote attaches to the uterine lining; at 2 weeks, zygote is the size of the period at the end of this sentence.
Describe Stage 2- Period of the embryo
Time after Conception: 3 to 8 weeks
Major Activities of the Stage: Major systems, organs, and structures of the body develop; Period ends when first bone cells appear. At 8 weeks, embryo is about 2.5 cm long and weighs about 4g.
Describe Stage 3- Period of the fetus
Time after Conception: 9 weeks to birth (38 weeks)
Major Activities of the Stage: Rapid growth and further development of the body structures, organs, and systems.
What are the environmental influences on an unborn child?
TERATOGENS: Harmful agents in the prenatal environment that can have a negative impact on prenatal development and even cause birth defects.
CRITICAL PERIOD: A period that is so important to development that a harmful environmental influence can keep a bodily structure or behaviour from developing normally.
What are the four adaptive reflexes of a neonate?
- sucking
- swallowing
- coughing
- blinking
What are the physical changes that occur during infancy?
sitting, standing, and walking; physical and motor development proceeds from the head downward to the trunk and legs, so babies lift their heads before they sit, and sit before they walk, etc.
What are the physical changes that occur during puberty?
ejaculation, menarche. Adolescence begins with the onset of puberty–biological changes characterized by a period of rapid physical growth and change that culminates in sexual maturity.
What are the physical changes that occur during middle age?
Menopause–cessation of menstruation; men experience a gradual decline in their testosterone levels.
Piaget’s stages of cognitive development- What is the concept of assimilation and accommodation?
ASSIMILATION: The process by which new objects, events, experiences, or pieces of information are incorporated into existing schemas
ACCOMMODATION: The process by which existing schemas are modified and new schemas are created to incorporate new objects, events, experiences, or information
Define socialization:
- The process of learning socially acceptable behaviours, attitudes, and values
- Every one of us is born into a society
- To function effectively and comfortably within that society, we must come to know the patterns of behaviour that it considers desirable and appropriate.
What are the 8 psychosocial stages of development proposed by Erikson?
- Trust vs. mistrust
- Autonomy vs. shame and doubt
- Initiative vs. guilt
- Industry vs. inferiority
- Identity vs. role confusion
- Intimacy vs. isolation
- Generativity vs. stagnation
- Ego integrity vs. despair
What is the concept of separation anxiety?
- fear and distress when the parent leaves them with another caretaker
- infants show separation anxiety once the attachment has formed
What are the 4 types of attachment identified by Mary Ainsworth?
- secure
- resistant
- avoidant
- disorganized/disoriented
What are the 3 parenting styles outlined by Diane Baumrind?
- Authoritarian Parents - expect unquestioned obedience
- Authoritative Parents - set high standards, give rationale for rules.
- Permissive Parents - set few rules or limits
What are the 3 levels (6 stages) of moral development?
- Conventional - to gain approval or to follow the law.
- Postconventional - to ensure that human rights are protected.
- Preconventional - to avoid punishment or gain a reward.
Why is middle age often considered the prime of life?
Life satisfaction in older adults appears to be most strongly related to good health, as well as to a feeling of control over one’s life.
What are the five stages of coming to terms with death as proposed by Dr. Elisabeth Kubler-Ross?
- Denial and isolation
- Anger
- Bargaining
- Depression
- Acceptance
Define motivation.
The process that initiates, directs, and sustains behaviour to satisfy physiological or psychological needs.
Distinguish between intrinsic and extrinsic motivation.
Intrinsic Motivation: The desire to perform an act because it is satisfying or pleasurable in and of itself.
Extrinsic Motivation: The desire to perform an act in order to gain a reward or to avoid an undesirable consequence.
Explain how instinct can affect motivation.
Instinct theory: the notion that we are motivated by certain innate, unlearned tendencies that are part of the genetic makeup of all individuals.
EX. Two people fight because of their aggressive instinct.
Describe how instinct theory is related to human motivation.
Instinct we were born with may motivate us to behave a certain way. Clark Hull suggests all living organisms have certain biological needs that must be met if they are to survive.
Although, common experience alone suggests that human behaviour is too richly diverse, and too unpredictable, to be considered fixed and invariant across our species. Most psychologists reject the instinct theory as an explanation of human motivation.
Describe a motivational sequence using the drive-reduction theory.
A need creates an unpleasant state of arousal or tension called a drive. This drive impels the organism to engage in behaviour that will satisfy the need and reduce the tension.
EX. A person eats to reduce hunger
Define Homeostasis.
The tendency of the body to maintain a balanced internal state with regard to body temperature, blood sugar, water, oxygen level, and so forth to ensure physical survival.
Describe the arousal theory of motivation.
A theory suggesting that the aim of motivation is to maintain an optimal level of arousal.
If arousal is less than the optimal level, we do something to stimulate it.
If arousal exceeds the optimal level, we seek to reduce it.
EX. A person climbs a mountain for excitement; a person listens to classical music for relaxation
Relate arousal to the Yerkes-Dodson law.
The principle that performance on tasks is best when arousal level is appropriate to the difficulty of the task - higher arousal for simpler tasks, moderate arousal for tasks of moderate difficulty, and lower arousal for complex tasks.
List, in order, the needs found in Maslow’s hierarchy of needs.
- (Bottom of pyramid). Physiological Needs
EX. food, water, oxygen, sleep, elimination - Safety Needs
EX. Need for safety and seurity - Belonging and Love Needs
EX. Need to love andbe loved; need to affiliate with others and be accepted
4.Esteem Needs
EX. Needs to achieve, to gain competence, to gain respect and recognition from others. - Need for Self-Actualization
EX. Need to realize ones full potential.
Differentiate extracellular and intacellular thirst.
Extracellular thirst: Fluid is lost from body tissues. Ex. exercising, hot weather makes you perspire and loose body fluid as well as bleeding, vomiting, and diarrhea.
Intracellular thirst: Loss of water from inside the body cells.
Ex. Eating a lot of salty food.
Describe the relationship of blood sugar to hunger.
Blood levels of sugar called glucose are monitored by nutrient detectors in the liver, and send this information to the brain. Hunger is stimulated when the brain receives the message that the blood sugar is low. When glucose is high, insulin is released to convert the glucose into energy. Elevated insulin levels can cause an increase in hunger, food intake, and desire for sweets.
Describe the relationship of the hypothalamus to hunger.
Two areas of the hypothalamus are important in regulating eating behaviour and the hunger drive.
The lateral Hypothalamus (LH) acts as a feeding center signalling animals to eat. When the LH is destroyed the animal initially refuses to eat.
The Ventromedial Hypothalamus (VMH) acts as a satiety center. Stops eating. When this area is destroyed is causes overeating which leads to obesity.
List biological factors that stimulate eating.
- Activity in lateral hypothalamus
- Low blood sugar levels of glucose
- Increase in insulin
- Stomach contractions
- Empty stomach
List environmental factors that stimulate eating.
- Aroma of food
- Sight of appetizing food
- Taste of appetizing food
- Acquired food preferences
- Being around others who are eating
- Foods high in fat and sugar
- Learned eating habits
- Reaction to boredom, stress, unpleasant emotional state
Define the need for achievement.
The need to accomplish something difficult and to perform at a high standard of excellence.
Describe three components of emotions.
Physical Component - Physiological arousal (internal body state accompanying emotion).
Cognitive Component - The way we interpret a stimulus or situation.
Behavioural Component - Outward expression of the emotion (facial expressions, gestures, body posture, tone of voice).
Briefly describe the James-Lange theory of emotion.
The theory that emotional feelings result when we become aware of our physiological response to an emotion-provoking stimulus) . Ex. we are afraid because we tremble.
Briefly describe the Cannon-Bard theory of emotion.
The theory that physiological arousal and the feeling of emotion occur simultaneously after an emotion-provoking stimulus is relayed to the hypothalamus and the cerebral cortex.
Briefly describe Schachter’s cognitive theory.
A two-stage theory stating that for an emotion to occur,there must be (1) physiological arousal and (2) an interpretation or explanation of the arousal.
Briefly describe the Lazarus cognitive-appraisal theory of emotion.
The theory that an emotion-provoking stimulus triggers a cognitive appraisal, which is followed by the emotion and physiological trigger.
List the six primary emotions.
- Fear
- Anger
- Disgust
- Surprise
- Joy or Happiness
- Sadness or Distress
Discuss the role of emotion as a form of communication.
- Enables us to communicate our feelings, intentions, and needs more effectively.
- Make it more likely that others respond to us.
- we motivate others to act.
Define social psychology.
The study in which the way the actual, imagined, or implied presence of others influences the thoughts, feelings, and behaviour of individuals.
Describe the primacy effect.
The likelihood that an overall impression or judgement of another will be influenced more by the first information received about that person than by information that comes later.
Explain the difference between a situational attribution and a dispositional attribution.
Situational attribution: Attribution of a behaviour to some external cause or factor operating in the situation; an external attribution.
Dispositional Attribution: Attribution of one’s own or another’s behaviour to some internal cause such as a personal trait, motive, or attitude; an internal attribution.
Define fundamental attribution error.
The tendency to overemphasize internal factors and underemphasize situational ones when explaining other people’s behaviour.
Define self-serving bias.
Our tendency to attribute our successes to dispositional causes, and our failures to situational causes.
Identify four factors that influence attraction.
Proximity - close to you
Reciprocal Liking - Liking those who like us
Attractiveness - good looks attract
Similarity
Distinguish between conformity and compliance.
Conformity: changing or adopting a behaviour or an attitude to be consistent with the norms of a group or the expectations of others.
Compliance: Acting in accordance with the wishes, the suggestions, or the direct requests of another person.
Describe the results of the Milgram Study.
He showed that a large majority of his participants would obey authority even if obedience caused great pain or was life-threatening to another person.
Define social facilitation.
Any positive or negative effect on performance due to the presence of others; either an audience effect or a co-action effect.
Define social loafing.
The tendency to put forth less effort when working with others on a common task than when working alone.
Define group polarization.
The tendency of members of a group, after group discussion, to shift toward a more extreme position in whatever direction they were leaning initially.
Define roles.
The behaviours considered to be appropriate for individuals occupying certain positions within a group.
Define groupthink.
The tendency of members of a very cohesive group to feel such pressure to maintain group solidarity and to reach agreement on an issue that they fail to adequately weigh available evidence or to consider objections and alternatives.
Explain how groupthink may contribute to poor decision making.
- Group is more concerned with preserving group solidarity and uniformity than with objectively evaluating all possible alternatives in decision making, individual members may hesitate to voice any dissent.
- Group may discredit opposing views from outsiders.
Define attitude.
A relatively stable evaluation of a person, object, situation, or issue.
Describe the belief components of attitude.
The Cognitive component - thoughts and beliefs about attitudinal object.
Describe the emotional component of attitude.
The emotional component - feelings toward attitudinal object.
Describe the action component of an attitude.
The Behavioural component - predisposition to act toward attitudinal object.
Explain cognitive dissonance.
The unpleasant state that can occur when people become aware of inconsistencies between their attitudes or between their attitudes and behaviour.
Describe methods of reducing cognitive dissonance.
- Changing our behaviour
- Changing our attitude
- Somehow explaining away the inconsistency
- Reducing its importance.
EX. Smoking. Easiest way to reduce cognitive dissonance - change the behaviour (Quit smoking). Or Change in attitude (convincing themselves it is not as dangerous as research suggests).
