Q

Define consolidation

A

the process by which short-term memory is converted to long-term memory

48
Q

What is long-term potentiation?

A

After brief periods of stimulation, an increase in the synaptic strength between two neurons leads to stronger electrochemical responses to a given stimuli. The neurons involved in the circuit develop increased sensitivity, which results in an increased potential for neural firing after a connection has been stimulated.

49
Q

If a person gets a concussion, which memories will not be wiped out?

A

those that have long-term potentiatied

50
Q

In observational learning, what is modeling?

A

Q

What are mirror neurons?

A

They are neurons that fire both when an individual performs a task and when they observe another individual performing the task.

52
Q

What emotions might mirror neurons be involved with?

A

vicarious emotions: empathy

53
Q

What is the elaboration likelihood model?

A

It explains whether people will be influenced by the content of a speech or by other, more superficial characteristics (like the appearance of the orator). If a person is interested in the topic and not distracted, they will pay attention to the content. If they are distracted, they will pay attention to superficial aspects.

54
Q

What 3 elements may have an impact on persuasiveness?

A
  • Message characteristics: features of the message itself
  • Source characteristics: the person/venue delivering the message
  • Target characteristics: the person receiving the message
55
Q

In persuasion, what is the central route?

A

A cognitive route in which people are persuaded by the content of the argument

56
Q

In persuasion, what is the peripheral route?

A

A cognitive route in which people are persuaded by superficial or secondary characteristics of a speech/orator

57
Q

Which type of processing route has a longer-lasting effect on persuasion: central or peripheral route?

A

central route

58
Q

What is social cognitive theory?

A

It is a theory of behavior change that emphasized the interactions between people and their environment.

59
Q

What is reciprocal determinism?

A

It is the interaction between a person’s behaviors, personal factors, and environment. People both shape and are shaped by their environments.

60
Q

What is behavioral genetics?

A

Researching how the genotype and evironment affect the phenotype of an individual

61
Q

What are twin studies?

A

To study the effect of genetics and environment on phenyotype, researcheers compare traits in monozygotic (identical) and dizygotic (fraternal) twins

62
Q

Are monozygotic female twins or male twins more identical and why?

A

Monozygotic male twins are more identical because X inactivation in female somatic cells is not identical between the female twins.

63
Q

What are adoption studies?

A

To study the effect of genetics and environment on phenotype, researchers study adopted inviduals’ traits in comparison to their genetic relatives’ and environmental revlatives’ traits.

64
Q

Define heritability

A

It is a statistic used to estimate how much of the genetic variation of a phenotypic trait in a population is due to genetic differences in that population (ex: studying height, focus on how genetics factors play a role in the differences in height between people).

65
Q

What are transgenic mice?

A

66
Q

What are knockout mice?

A

A gene of interest has been inactivated.

67
Q

What are reflexive movements?

A

They are primitive, involuntary movements that serve to “prime” the neuromuscular system and form the basis for more sophisticated movement to come. These occur during a child’s first year.

68
Q

What are rudimentary movements?

A

They are the first voluntary movements performed by a child up until age 2. These include rolling, sitting, crawling, standing, and walking.

69
Q

What are fundamental movements?

A

From age 2-7, children learn to manipulate their body through actions such as running, jumping, throwing, etc.

70
Q

What is specialized movement?

A

From ages 7-14, children learn to combine fundamental movements and apply them to specific tasks.

  • transitional substage: combination of movements
  • application substage: conscious decisions to apply these skills to specific types of activity
71
Q

What is the lifelong application stage of movement?

A

From ages 14-on, people continually refine and apply movements to many types of activities.

72
Q

At birth, what does an infant’s neuronal makeup look like?

A

It has the highest number of neurons than at any other point in its life, but does not have many neural networks (codified routes for information processing).

73
Q

What is infantile amnesia?

A

Humans are unable to recall memories until around age 3.5, but are still capable of learning and memory.

74
Q

What did Harry and Margaret Harlow determine from their experiments with monkey development?

A

Infant monkeys grew attached to comfortable contact (blanket, cloth-mother), rather than the bottle-mother. Without a real mother, they grew up demostrating social deficits with other monkeys.

75
Q

In Mary Ainsworth’s strange situation experiments, how did the securely attached infants respond?

A

They played and explored in the presence of their mothers but felt distress when she left. When she returned, they sought contact and were easily consoled.

76
Q

In Mary Ainsworth’s strange situation experiments, how did the insecurely attached infants respond?

A

They did not explore their surroundings or play even in the presence of their mother. When she left, they would cry or display indifference.

77
Q

Describe the authoritarian parenting style

A

attempting to control children with strict rules that are expected to be followed unconditionally

78
Q

Describe the permissive parenting style

A

allowing children to lead, rarely disciplining them, and are very lenient

79
Q

Describe the authoritative parenting style

A

listen to children, encourage independence, place limits, and consistently follow through with consequences

80
Q

During adolescence, what three major changes occur in the brain?

A
  • cell proliferation
  • synaptic pruning
  • myelination
81
Q

Define encoding

A

process of transferring sensory information into our memory system

82
Q

What are the primacy and recency effects in the serial position effect?

A

primacy: first items are more easily recalled because they have had the most time to be encoded
recency: last items are more easily recalled because they may still be in the phonological loop

83
Q

What is chunking?

A

Information to be remembered is organized into discrete groups of data (ex: telephone digits separated into chunks)

84
Q

What are heirarchies in terms of memorization?

A

They are groups of information (ex: types of birds vs. types of cats at the zoo)

85
Q

What is depth of processing in terms of memorization?

A

Information that is thought about at a deeper level is better remembered.

86
Q

What is the dual coding hypothesis?

A

It is easier to remember words with associated images than either words or images alone.

87
Q

What is the method of loci?

A

using a memory palace

88
Q

What is the self-reference effect?

A

It is easier to remember things that are personally relevant because it interacts with our own views or it can be linked to existing memories.

89
Q

What is sensory memory?

A

the initial recording of sensory information in the memory system

90
Q

What are the two types of sensory memory?

A
  • iconic memory: brief photographic memory for visual information (less than a second)
  • echoic memory: brief memory for sound (3-4 seconds)
91

99
Q

What are the nodes in our long-term memory network?

A

individual ideas (like cities on a map)

100
Q

What are the associations in our long-term memory network? How does these impact our ability to retrieve information?

A

They connect nodes (like roads between cities on a map). We can retrieve information more quickly if we have stronger associations (more frequent/deep connections). We can also add connections by processing material in dffierent ways.

101
Q

What is prospective memory?

A

remembering to do things in the future

102
Q

What is the response threshold in our long-term memory network?

A

A node must receive enough input signals (summation) from its neighbors to become activated.

103
Q

What is spreading activation in our long-term memory network?

A

When trying to retrieve information, we start the search from one node. We do not “choose” where to go nest, but rather the activated node spreads its activation to other nodes around it to an extent related to the strength of association between that node and each other.

104
Q

What is mood-dependent memory?

A

What we learn in one state is most easily recalled when we are once again in that emotional state.

105
Q

What is the difference between cued recall and recognition?

A

Cued recall involves retrieving information when provided with a cue (given countries, name all the capitals of the world). Recognition involves identifying specific information from a set of information that is presented (multiple choice).

106
Q

What is the misinformation effect?

A

A tendency to misremember after a person is exposed to subtle misinformation.

107
Q

What is anterograde amnesia?

A

inability to encode new memories

108
Q

What is retrograde amnesia?

A

ability to recall information that was previously encoded

109
Q

What is proactive interference?

A

Information previously learned interferes with the ability to recall information learned later.

110
Q

What is retroactive interference?

A

New learned information interferes with the recall of information learned previously.

111
Q

What is positive transfer?

A

Old information facilitates the learning of new information.

112
Q

How are false memories formed?

A

They may result from the implanting of ideas (ex: if you repeatedly imagine getting lost as a child in a mall, this imagined occurence would begin to feel familiar and take on some sort of real memory).

113
Q

What is an error source monitoring?

A

Being able to recognize someone, but not knowing where you’ve seen them before or attributing an action to a person when in reality it was a dream.

114
Q

What is neural plasticity?

the maleability of the brain’s pathways and synapses based on behavior, the environment, and neural processes

115
Q

Where has neurogenesis occured?

A

hippocampus and cerebellum

116
Q

What is the best explanation for the physical basis of memory?

A

Learning and memory over a lifetime involves increased interconnectivity of the brain through increasing synapses between existing neurons, forming a neural net.
