Q

What are the four stages of Piaget stages of cognitive development

A

Sensorimotor (birth-2): Key milestone and sensorimotor stage of the development of object permanence

Preoperational (2-7) Characterized by symbolic thinking egocentrism and centration

Concrete operational (7-11) Children understand conservation, consider the perspective of others are able to think logically as long as they are working with concrete objects or information have not yet developed the ability to think abstractly

Formal operational (11+) Marked by the ability to think logically about abstract ideas

A

Melatonin from the pineal gland.

The retina is connected to the hypothalamus which controls the pineal gland thus decreasing light can cause the release of melatonin

38
Q

What role does cortisol play in the sleep wake cycle?

A

Cortisol is a steroid hormone produced in the adrenal cortex. Cortisol level slowly increase during the early morning due to a series of events triggered by light that eventually stimulates cortisol release.

39

Quieting the mind for some purpose whether spiritual religious or for counseling or psychotherapy because it produces a sense of relaxation and relief from anxiety and worry

Resemble stage one sleep with data and slow alpha waves

50
Q

What EEG waves are associated with being awake

A

Beta and alpha

51
Q

Depressant

A

Reduce nervous system activity resulting in a sense of relaxation and reduced anxiety. Alcohol is the most common.

52
Q

Alcohol

A

A type of depressant. Increases dopamine levels which caused mild sense of euphoria.

53
Q

Barbiturates and Benzodiazepines

A

Anxiety reducing and sleep medication

Increase GABA of relaxation.

Benzodiazepines are less prone to overdose.

54
Q

Stimulants

A

Cause an increase in arousal in the nervous system.

Examples include amphetamines and cocaine and ecstasy

55
Q

Amphetamines

A

Cause increased arousal by increasing release of dopamine norepinephrine and serotonin at the synapse and decreasing their reuptake

56
Q

Cocaine

A

Decreases reuptake of dopamine norepinephrine and serotonin.

Has anesthetic and vasoconstrictive properties.

57
Q

Ecstasy

A

Acts as a hallucinogen as well as an amphetamine.

Causes increased heart rate, increased blood pressure, blurry vision, sweating nausea and hypothermia.

Causes feelings of euphoria increased alertness and an overwhelming sense of well-being and connectedness

58
Q

Opiates/Opiods

A

Bind to opioid receptors in the peripheral and central nervous system causing a decrease reaction to pain in a sense of euphoria

A number of drugs derived from opiates include morphine, codeine, oxycodone, hydrocodone, and heroin

59
Q

Heroin

A

Also known as diacetylmorphine originally created as a substitute for morphine. Once injected the body metabolizes heroin into morphine.

60
Q

Hallucinogens

Examples?

How does it exert its effects?

A

Include drugs such as LSD, ketamine, mescaline, ecstasy, psilocybin.

Exert their effects through a complex interaction between various neurotransmitters especially serotonin.

Distort Reality and fantasy enhancement of sensory experiences.



61
Q

Marijuana

Inhibits what? Increases what?

Active chemical?

Has what physiological effect?

A

The active chemical in marijuana THC inhibits GABA activity and indirectly increases dopamine activity causing pleasure.

Physiological effects include redness, dry mouth, fatigue, impairment of short-term memory, increased heart rate, increased appetite, lower blood pressure psychologically it falls into the category of stimulant depressant hallucinogen.

62
Q

Selective attention

A

Focusing on one part of the sensorium about ignoring other stimuli

63
Q

Controlled vs Automatic Processing

A

Newer complex tasks that require undivided attention versus familiar routine tasks

64
Q

What are the five basic components of language

A 
phonology 
morphology 
semantics 
syntax
pragmatics
65
Q

Phonology

A

The actual sound of language

66
Q

Morphology

A

Structure of words

Building blocks of words

re- design- -ed

67
Q

Semantics

A

The association of meaning with a word

68
Q

Syntax

A

Putting words together to form sentences

69
Q

Pragmatics

A

Dependence of language and context on pre-existing knowledge

How you word things may be determined by how well you know someone.

70
Q

Prosody

A

The rhythm cadence and inflection of our voices

71
Q

Timeline of language acquisition

A 
9-12 months- Babbling 
12-18 months- one word per month 
18-20 months- explosion of language and combining words 
2 to 3 years- longer sentences 3+ words 
5 years- language rules largely mastered
72
Q

Nativist (Biological) Theory

A

The existence of some innate capacity for language

73
Q

Language acquisition

A

Innate ability, a theoretical pathway in the brain that allows infants to process and absorb language rules

74
Q

Critical Period

A

Necessary age range for optimal language development. Thought to be between two years of age of puberty. If no language exposure occurs at the same litter training is largely ineffective

75
Q

Learning (Behaviorist) Theory

A

Explains language acquisition by operate conditioning.

Parents and take a picture pee and reinforce sounds that sounds like language spoken by the parents overtime and fat perceive certain sounds a little value and they’re not reinforced what other sounds of value in a reliable reinforced by parents and caregivers

76
Q

Social Interactionist Theory

A

Focuses on the interplay between biological and social processes. Language acquisition is driven by the child desire to communicate and behave in a social manner. 

77
Q

Linguistic Relativity Hypothesis

A

The way that we think about the world is determined by the content of language. Language affects the way we think rather than the other way around.

78
Q

Brocas vs Wernicke’s area

A

Both located in the dominant hemisphere (usually the left hemisphere)

Brocas:
Located in the inferior frontal gyrus of the frontal lobe controls the motor function of speech

Wernickes:
Located in the superior temporal gyrus of the temporal lobe responsible for language comprehension

79
Q

What structure connects the Wernickes and Broca’s areas?

A

Arcurate Fasiculus

80
Q

Aphasia

A

Deficit of language production or comprehension

81
Q

Brocas aphasia

A

Absent ability to produce spoken language

Aka expressive aphasia

82
Q

Wernickes aphasia

A

Motor production and fluency is retained but comprehension of speech is lost. These patients speak nonsensical sounds an inappropriate word combinations devoid of meaning.

83
Q

Conduction Aphasia

A

When the connection between the Brocas and wernickes area of the brain is impaired speech production and comprehension are intact but the patient is unable to repeat something that has been said.
