Q

defn: the four key components of the information processing model

A
  1. thinking requires sensation, encoding, and storage of stimuli
  2. stimuli must be analyzed by the brain (not responded to automatically) to be useful in decision making
  3. decisions make in one situation can be extrapolated and adjusted to help solve new problems (situational modification)
  4. problem solving is dependent not only on the person’s cognitive level, but also on the context and complexity of the problem

primary circular reactions: repetitions of body movements that orig. occurred by change

secondary circular reactions: manipulation is focused on something outside the body

object permanence: objects continue to exist even when out of view

marks the beginning of representational thought: create mental representations of external objects and events

  1. dreaming
  2. memory consolidation
56
Q

A

reduce nervous system activity = relaxation, reduced anxiety

alcohol
downers/sedatives (calm and induce sleep)

71
Q

effects of alcohol on the brain + outward behavior

A
  1. increases activity of the GABA receptor (causes hyperpolarization of the membrane –> causes generalized brain inhibition at the physiological level –> diminished arousal at moderate doses)
  2. lack of self-control (disinhibition) –> bc the centers of the brain that prevent inappropriate behavior are also depressed
  3. increases dopamine levels –> mild euphoria
  4. affects logical reasoning, motor skills, fatigue
  5. alcohol myopia (the inability to recognize consequences of actions)
72

74
Q

defn + func + ex: sedatives

A

depress CNS activity = calm, relaxed, drowsy

barbiturates (anxiety-reducing and sleep, archaic)

benzodiazepines (modern, less prone to overdose)

increase GABA activity –> relaxation

highly addictive

75
Q

defn + func + ex: stimulants

A

cause an increase in nervous system arousal

each drug increases the frequency of action potentials, but by different mechanisms

amphetamines, cocaine, ecstasy/MDMA

76
Q

func + effects: amphetamines

A

caused increased arousal by increasing release of dopamine, norepinephrine, and serotonin at the synapse and decreasing their reuptake –> increases arousal, reduces appetite, decreases need for sleep

increased HR, BP

euphoria, hypervigilance (on edge), anxiety, delusions of grandeur, paranoia

prolonged use: stroke, brain damage

withdrawal: depression, fatigue, irritability

77
Q

func + effects: cocaine

A

decreases reuptake of doapmine, norephinephrine, and serotonin

similar effects to amphetamines

also has anesthetic and vasoconstrictive properties

highly addictive

crack is the smokeable form

78
Q

func + effects + aka: opiates and opioids

A

types of narcotics

aka painkillers

OPIATES = naturally occurring forms (morphine, codeine)

OPIOIDS = semisynthetic derivatives (oxycodone, hydrocodone, heroin)

bind to opioid receptors in the PNS and CNS

act as endorphin agonists, cause decreased reaction to pain and a sense of euphoria

overdose: respiratory suppression

79
Q

func + effects + class: heroin

A

an opioid

originally created as a substitute for morphine

is rapidly metabolized to morphine

80
Q

func + effects + ex: hallucinogens

A

cause introspection, distortions of reality and fantasy, and enhancement of sensory experiences

increased HR, BP, pupil dilation, sweating, increased body temp

LSD, peyote, mescaline, ketamine, psilocybin mushrooms

complex interaction between various neurotransmitters, especially serotonin

81
Q

effects + func: marijuana

A

active chemical = tetrahydrocannabinol (THC)

acts on cannabinoid receptors, glycine receptors, and opioid receptors which interact to create a high

inhibits GABA activity, indireclty increases dopamine activity (causing pleasure)

eye redness, dry mouth, fatigue, increased appetite, low BP

pscyhological effects fall into stimulant, depressant, and hallucinogen categories

82
Q

defn: mesolimbic reward pathway

A

highly related to drug addiction

one of four dopaminergic pathways in the brain

includes the nucleus accumbens (NAc), the ventral tegmental area (VTA), and the connection between them (the medial forebrain bundle MFB)

normally involved in motivation and emotional response

its activation accounts for the positive reinforcement of substance use

activated by all substances that produce pscyhological dependence, also by gambling and falling in love

83
Q

defn: attention

A

concentrating on one aspect of the sensory environment ( sensorium)

84
Q

defn: selective attention

A

focusing on one part of the sensorium while ignoring other stimuli

acts as a filter between sensory stimuli and our processing systems

if a stimulus is attended to: it is passed through a filter and analyzed further

if the stimulus is not attended to: it is lost

NOT all-or-nothing

85
Q

defn: cocktail party phenomenon

A

selective attention is a filter that allows us to focus on one thing while allowing other stimuli to be processed in the background

only if the stimuli are particularly important, do we shift our attention to them

you are at a party talking to a friend, and you hear your name across the room

86
Q

defn: dichotic listening tests

A

designed to test selective attention

listen to headphones with distinct auditory stimuli going to each ear

participants are then asked to pay attention to either or both stimuli, then asked to repeat out loud what they heard in the attended ear (shadowing)

participants must filter out information from the unattended ear

87
Q

defn: divided attention

A

the ability to perform multiple tasks at the same time

88
Q

defn: controlled (effortful) vs. automatic processing

A

most new or complex tasks require undivided attention (utilize CONTROLLED processing)

familiar or routine actions can be performed with AUTOMATIC processing (permits the brain to focus on other tasks with divided attention) –> does not allow for innovation or rapid response to change
