Q

Between what ages does the sensorimotor stage occur? And what happens during this stage?

A

The first stage is the sensorimotor stage, starting at birth and lasting until about two years of age.

In this stage, a child learns to manipulate his or her environment in order to meet physical needs.

Q

What are secondary circular reactions?

A

Occurs when manipulation is focused on something outside the body, such as repeatedly throwing toys from a high chair. These behaviors are often repeated because the child gets a response from the environment (such as a parent picking up the dropped toy).

Q

What ages does the concrete operational stage occur? And what happens during this stage?

A

The concrete operational stage lasts from about 7 to 11 years of age.

In this stage, children can understand conservation and consider the perspectives of others. Additionally, they are able to engage in logical thought as long as they are working with concrete objects or information that is directly available.

They still CANNOT think abstractly.

Q

Role of Culture in Cognitive Development

A

One’s culture will determine what one is expected to learn. Some cultures will place a higher value on social learning, including cultural traditions and roles, while other cultures will value knowledge. In addition, one’s culture will also influence the rate of cognitive development as children are treated very differently from culture to culture.

Intuition

A

Can be defined as the ability to act on perceptions that may not be supported by available evidence. Utilizes “gut feeling”.

39
Q

Howard Gardner’s Theory of Multiple Intelligences

A

Has 7 different types of intelligence. Gardner argues that linguistic ability and logical-mathematical ability are the most valued in Western cultures. Hence, our IQ tests measures these.

40
Q

Beta Waves

A

Have a high frequency and occur when the person is alert or attending to a mental task that requires concentration. Beta waves occur when neurons are randomly firing.

41
Q

Alpha Waves

A

Occur when we are awake but relaxing with our eyes closed, and are somewhat slower than beta waves. Alpha waves are also more synchronized than beta waves.

42
Q

What is the sequential order of brain waves?

A

beta, alpha, theta, delta (BAT-D)

43
Q

What is the significance of REM sleep?

A

The mind appears close to awake on EEG, but the person is asleep.
Eye movements and body paralysis occur in this stage.
Dreaming in REM focuses on consolidating procedural memories.

44
Q

Melatonin

A

Causes sleepiness.

45
Q

Cortisol

A

Contributes to wakefulness.

46
Q

When does most dreaming occur?

A

During REM sleep.

47
Q

Dyssomnias

A

Disorders that make it difficult to fall asleep, stay asleep, or avoid sleep (ex: insomnia, narcolepsy, and sleep apnea).

48
Q

Parasomnias

A

Abnormal movements or behaviors during sleep (ex: night terrors & sleep walking).

49
Q

What stage of sleep does most sleep disorders occur?

A

NREM sleep

50
Q

Hypnosis

A

A state of consciousness in which individuals appear to be in control of their normal faculties but are in a highly suggestible state.

Hypnosis is often used for pain control, psychological therapy, memory enhancement, weight loss, and smoking cessation.

51
Q

Meditation

A

Involves a quieting of the mind and is often used for relief of anxiety. It has also played a role in many of the world’s religions.

52
Q

Depressants

A

Reduce nervous system activity, resulting in a sense of relaxation and reduced anxiety.

They increase or mimic GABA activity in the brain.

53
Q

What are some types of depressants?

A

Alcohol, barbiturates, and benzodiazepines.

54
Q

Stimulants

A

Causes an increase in arousal in the nervous system. They increase dopamine, norepinephrine, and serotonin concentration at the synaptic cleft.

It increases their release and decreases their reuptake.

55
Q

What are some examples of stimulants?

A

Amphetamines, cocaine, and ecstasy.

56
Q

Opiates and Opioids

A

Causes a decreased reaction to pain and feelings of euphoria. They can cause death by respiratory depression.

57
Q

What are some examples of opiates and opioids?

A

Heroin, morphine, opium, and prescription pain medications such as oxycodone and hydrocodone.

58
Q

Hallucinogens

A

Typically causes distortions of reality and fantasy, enhancement of sensory experiences, and introspection. Physiologic effects include increased heart rate and blood pressure, dilation of pupils, sweating, and increased body temperature.

59
Q

What are some examples of hallucinogens?

A

LSD, peyote, mescaline, ketamine, and psilocybin-containing mushrooms.

60
Q

Marijuana

A

Has depressant, stimulant, and hallucinogenic effects. Its active ingredient is tetrahydrocannabinol.

THC increases GABA and dopamine (causing pleasure) activity.

61
Q

What classification of drugs does not increase GABA activity?

A

Hallucinogens

62
Q

What pathway in the brain is drug addiction related to?

A

Mesolimbic reward pathway. Dopamine is the main neurotransmitter in this pathway/

63
Q

Selective attention

A

Allows one to pay attention to a particular stimulus while determining if additional stimuli in the background require attention.

64
Q

Cocktail Party Phenomenon

A

Allows us to determine if a background stimuli needs attention.

65
Q

Divided Attention

A

Uses automatic processing to pay attention to multiple activities at one time.

66
Q

Phonology

A

Refers to the actual sound of speech.

67
Q

Morphology

A

Refers to the building blocks of words, such as rules for pluralization (–s in English), past tense (–ed  ), and so forth.

68
Q

Semantics

A

Refers to the meaning of words. ex: Young children struggle with this. They categorize all women as mommy.

69
Q

Syntax

A

Refers to the rules dictating word order.

70
Q

Pragmatics

A

Refers to the changes in language delivery depending on context.

ex: Asking a friend vs. stranger if you could sit next to them.

71
Q

Nativist (biological) Theory

A

By Noam Chomsky. He explains language acquisition as being innate and controlled by the language acquisition device (LAD).

72
Q

Learning (behaviorist) Theory

A

By B.F. Skinner. Explains language acquisition as being controlled by operant conditioning and reinforcement by parents and caregivers.

73
Q

Social Interactionist Theory

A

Explains language acquisition as being caused by a motivation to communicate and interact with others.

74
Q

“Whorfian (linguistic relativity) Hypothesis

A

States that the way we view and interpret the world is determined by language.

75
Q

Where are speech areas in the brain normally found?

A

In the dominant hemisphere. Usually the left.

76
Q

Broca’s Area

A

The motor function of speech is controlled by Broca’s area. Damage results in Broca’s aphasia, a nonfluent aphasia in which generating each word requires great effort.

77
Q

Wernicke’s Area

A

Language comprehension is controlled by Wernicke’s area. Damage results in Wernicke’s aphasia, a fluent, nonsensical aphasia with lack of comprehension.

78
Q

What connects Broca’s area to Wernicke’s area?

A

The arcuate fasciculus connects Wernicke’s area and Broca’s area. Damage results in conduction aphasia, marked by the inability to repeat words that have just been spoken despite intact speech generation and comprehension.

79
Q

Base Rate Fallacy
