Q

What develops during the sensorimotor stage of Piaget’s stages

A

Sensorimotor stage is stage 1: it occurs from 0-2

Q

What develops during the preoperational stage of Piaget’s stages

A

The preoperational stage is stage 2: it occurs from 2-7
Children can play pretend and start to use symbols to represent things
This stage is associated with an inability to understand the perspective of others (egocentric stage)

Q

What develops during the concrete operational stage of Piaget’s stages

A

The concrete operational stage is stage 3: it occurs from 7-11
Children begin to learn empathy and math skills
This stage is associated with understanding concrete events logically and the concepts of conservation and reversibility

Q

What develops during the formal operational stage of Piaget’s stages

A

The formal operational stage is stage 4: It occurs in kids 12 and up
Children are reasoning more like adults and it continues to develop with time
In this stage a child will be able to think about hypothetical situations and engage in logical through about abstract ideas and problem solving

Q

Theory of primary mental abilities

A
  • L.L. Thurnstone
  • there are 7 factors of intelligence: word fluency, verbal comprehension, spatial reasoning, perceptual speed, numerical ability, inductive reasoning, and memory

Q

Theory of multiple intelligence

A

Howard Gardner
There are 9 aspects of intelligence that are independent of one another: logical-mathematical intelligence, verbal-linguistic, spatial-visual, bodily-kinesthetic, interpersonal, intrapersonal, musical, then naturalist, and existential intelligence

25
Triarchic theory of intelligence
Robert Sternberg | 3 independent intelligences based on real world success: analytical, creative, and practical intelligence
26
Theory of general intelligence
Charles Spearman There is one general intelligence: g factor can predict our intelligence in multiple academic areas This theory is supported by research
27
Cognitiva abilities that decline as you age
- Recall - Episodic memory - Process speed - Divided attention
28
Cognitive abilities that stabilize with age
- Implicit memory (like riding a bike) - Recognition memory
29
Cognitive abilities that improve with age
- Semantic memory [verbal skills] (improves until 60) - Crystallized intelligence - Emotional reasoning
30
Where are the language centers in the brain?
Language is in the left hemisphere The Broca's area controls speaking/language expression located in the frontal lobe The Wernicke's area is where sound processing and language understanding occurs in the temporal lobe
31
Limbic System
A set of structures in the brain (Hypothalamus, Amygdala, Thalamus, and Hippocampus) This system is responsible for the storage/retrieval of memories, especially ones tied to emotions
32
Thalamus
The thalamus is the sensory relay station: all senses except smell pass through the thalamus which directs the impulse to the appropriate cortex
33
Amygdala
Amygdala is the aggression center - it produces anger/violence and fear/anxiety - if there is damage to this area it can result in drunken behaviors
34
Hippocampus
Hippocampus plays a key role in forming new memories - converts short term memory to long term memory - if there is damage to the area new memories cannot be made
35
Hypothalamus
The hypothalamus regulates the autonomic nervous system - controlling endocrine system and triggering the release of hormones
36
Which side of the brain shows more activity with positive emotions and what side shows more activity with negative emotions
Positive emotions evoke more activity on the left side and negative emotions evoke more activity on the right side
37
Two branches of the autonomic nervous system?
Sympathetic (fight or flight) and parasympathetic (rest and digest)
38
What happens to the body when the sympathetic branch of the nervous system is activated?
- Pupils dilate - decrease in salivation - increase in respiration and heart rate (more O2) - increase in glucose release (glucagon) - increase in adrenaline and norepinephrine - decrease in digestion
39
What happens to the body when the parasympathetic branch of the nervous system is activated?
- Pupils constrict - increase salivation - normal respiratory and heart rate - increase glucose storage (insulin) - increase digestion
40
6 universal emotions according to Paul Ekman
Happiness, sadness, fear, disgust, anger and surprise
41
James - Lange theory of emotion
Event causes a physiological response -> the interpretation of the physiological response leads to the emotion
42
Cannon-Bard theory of emotion
The event causes a physiological response and emotion at the same time
43
Schachter-Singer theory of emotion
"Schachter two factor" Event causes a physiological response and a cognitive interpretation of the response simultaneously which then causes an emotion
44
Lazarus theory of emotion
The cognitive labeling of the event that occurred leads to an emotional response and a physiological response based on the label of the event
45
Parts of the frontal lobe
- Motor cortex (body movements) - Broca's area (speech production)
46
Components of the Parietal lobe
Somatosensory cortex (touch/ pressure/ pain) - spatial manipulation
47
Occipital lobe function
Vision
48
Temporal cortex function
Sound (Wernicke's area located here)
49
Maslow's Hierarchy of needs
1) Physiological [food, water, sleep] 2) Safety [needs are associated with stability, security, and protection] 3) Love [need to belong and be accepted, intimacy] 4) Self-esteem [confidence and recognition for skill] 5) Self- actualization [maximum potential]
50
Three components of attitude?
ABC MODEL - Affective (emotional - how we feel about things) - Behavioural (how we act or behave towards things) - Cognitive
51
What are the names of Freud's psychosexual development stages
``` Old Age Parrots Love Grapes Oral stage (0-1) Anal stage (1-3) Phallic stage (3-6) Latent period(6-12) Genital stage (12+) ```
52
Development that occurs in Freud's oral stage
Stage 1: 0-1 Focus is the mouth, baby develops a sense of trust and comfort Fixation here causes issues of dependency and aggression [smoking or biting finger nails and overeating seen in adults]
53
Development that occurs in Freud's Anal stage
Stage 2: 1-3 Focus on the anus (toilet training); leads to control and independence in the child, encourages child to feel positive outcomes Fixation here causes problems with orderliness and messiness
54
Development that occurs in Freud's Phallic stage
Stage 3: 3-6 Discover the difference between males and females (Oedipus [want to posses mother and replace father for males] and Electra [see mother as competition for father in females] complex Fixation at this stage causes homosexuality and exhibitionism
55
Development that occurs in Freud's latent period
Stage 4: 6-12 | Period of exploration - intellectual pursuits and social interactions and communication skills are developed
56
Development that occurs in Freud's genital stage
Stage 5: 12+ Focus on strong sexual interests and on the needs of others The goal is to establish balance between various life areas
57
What are the names of Erikson's Psychosocial development stages
1) Trust vs Mistrust (0-1) 2) Autonomy vs Shame/doubt (1-3) 3) Initiative vs Guilt (3-6) 4) Industry vs Inferiority (6-12) 5) Identity vs Role Confusion (12-20) 6) Intimacy vs Isolation (20-40) 7) Generativity vs Stagnation (40-65) 8) Integrity vs Despair (65+)
58
Stages of Kohlberg Moral Development
``` 1) Pre-Coventional (7-10) 1A) Obedience vs punishment 1B) Self interest 2) Conventional (10-16) 2A) Conformity and interpersonal accord 2B) Authority and social order 3) Postconventional stage (only achieved by 15% of people) 3A) Social contract 3B) Universal principles ```
