Q

Define Localizationist theory and name one piece of evidence that supports it

A

Says that language processing components are localized in specific parts of the cortex.
Broca’s patient could understand language but not speak. Postmortem examination of Broca patients’ brain showed a lesion in the posterior region of the frontal lobe. Wernicke’s patient could speak but not understand language and the location of the lesion in Wernicke’s patient was different from Broca’s patient. It was in at the junction of the temporal, parietal and occipital lobes

Q

Compare and contrast classical conditioning with instrumental conditioning

A

Both of these are types of associative learning in which associations between events are formed. Classical conditioning uses a conditional stimulus to eventually elicit a response. In the beginning, the conditional stimulus will not elicit any sort of response, for example, the bell ringing in Pavlov’s experiment. When the conditioned stimulus is paired with an unconditioned stimulus (which will elicit a response without training), the subject learns to eventually pair the conditioned stimulus with the unconditioned stimulus (whether it is presented or not) and consequently produce the response. Instrumental conditioning relies on using motivation to train the subject to associate a response with a meaningful stimulus. An example of this would be a rat learning to press a lever to receive food. The motivation is the food reward at the end. This type of conditioning requires complex neural circuits

Q

Recall from your readings that Bartlett was the researcher who used foreign folk tales to study memory. He found that memory was imperfect and, in fact, the retelling of the tale often left out portions that were inconsistent with the teller’s culture and incorporated incorrect information that was consistent with the teller’s culture. He called this type of memory ___.

Q

Name and define two types of nondeclarative memory.

A

Procedural memory: involves the learning of a variety of motor skills and cognitive skills.
Perceptual representation system: the priming of structure and form of objects and words by prior exposure

26
Q

Compare and contrast Broca’s aphasia and Wernicke’s aphasia

A

Broca’s aphasia is a condition where one can understand language but not speak it due to damage to inferior frontal gyrus, insula and ganglia. Patients with brocas aphasia appear normal in comprehension, but their speech is slow, articulation is impaired, and intonation is lacking.
Wernicke’s aphasia is where one can speak but cannot understand language. Caused by damage to primarily brodmans area 22, parietal, and occipital lobes. In these patients, speech is fluent and effortless. But the content is often jumbled, the words sound unintelligible, they have semantic paraphasia. They also have a hard time understanding the speech of others

27
Q

Define Long Term Depression

A

The decreased response …reduction in how efficient neuronal synapses are after some sort of conditioning. This will last hours or longer following a long patterned stimulus

28
Q

Phonological short term memory deals with what type of information?

A

For learning new phonological information having to do with sound.

29
Q

Short term memory for language is stored in a different area than that for spatial memory. Where are those areas located?

A

inferolateral region for language

And parietal and occipital region for spatial

30
Q

What is the evidence for different types of short term memory?

A

?

31
Q

Define habituation

A

To get used to a repeated stimulus and show decrease response

32
Q

S.M. was a patient whose amygdale were damaged, showed no fear when exposed to a variety of fear-producing stimuli. Later in life, she experienced a panic attack in a experiment that mimicked the effects of suffocation. What do these data suggest?

A

That the brain process threats from the external and internal world differently. It suggest that the amygdala processes external threats but not internal threats like suffocation or hunger…

33
Q

What is the Papez Circuit?

A

It’s a circuit in the central neural of emotion that includes the thalamus, hypothalamus, hippocampus, and cingulate cortex, amygdala, and PFC.

34
Q

Define source memory and what broader category of memory does it belong to (remember the flow chart in the video)?

A

Memory for where or from whom something was learned. It’s a declarative long term memory

35
Q

How is it demonstrated that young vervet monkeys seem to learn the details of how to apply an innate categorical vocabulary?

A

This is shown by showing how as the monkeys age they make fewer and fewer mistakes…-50%

36
Q

What is an agonist? In other words, if I am using a GABA agonist in an experiment, what would I expect to happen at a cellular/molecular level.

A

Agonist is a chemical that triggers a response when it binds. A GABA agonist would activate or enhance GABA effect which would inhibit neuron

37
Q

What did Darwin show about emotions that have been reproduced by other scientists?

A

that they are consistent across cultures…

38
Q

Name one piece of evidence that heredity plays an important role in ADHD?

A

Children with parents with ADHD are more likely to develop it themselves.

39
Q

Define syntax

A

Syntax: rules that specify how words are combined into phrases and sentences so that there is a clear meaning

40
Q

In your own words, what is Hebb’s rule?

A

That neurons that are constantly activated together will strengthen their synapse.

41
Q

What brain structure plays a role in social hierarchy and how was that demonstrated?

A

Amygdala. In an experiment with monkeys, the amygdala of the dominant monkey was removed which caused the monkey to be placed at the bottom of the social hierarchy.

42
Q

Name and define the two types of declarative memory

A

Episodic memory: recalling events in our lives

Semantic memory: recalling facts

43
Q

Why do we need “attention”? In other words, why would “attention” be useful to us in information processing?

A

Attention is defined as “selectively processing simultaneous sources of information”. This is important, because without it we would be overloaded by sensory information. We need the ability to pay specific attention to a certain task, conversation, etc..

44
Q

What do we mean by cognitive control?

A

Essentially our ability to adapt by…Switching from one plan to another by monitoring our ongoing actions.

45
Q

What is global aphasia?

A

This type of aphasia is a combination of Broca, Wernicke, and Conduction aphasias. Its caused by damage to anterior language region, basal ganglia, insula, posterior language region, and superior temporal gyrus. These patients cannot comprehend, repeat or speak meaningfully.

46
Q

Who was H.M. and what did he teach us about learning and memory?

A

H.M. was a patient who had undergone a bilateral medial temporal lobe resection to control his epilepsy, yet it left him with severe memory impairment. H.M. forgot daily events almost immediately, although there was no intellectual loss or perceptual disorder. He also underestimated his own age, could not remember names of people he had been recently introduced to, and felt that each day was it’s own separate new day without a past. The medial temporal lobe memory system was focused on when studying his defecits. We learned about what brain structures play important roles in the retention of current experience: the hippocampal gyrus and the anterior hippocampus (either together or separately). He helped us understand how memory functions are organized in the brain.

47
Q

Compare and contrast the James-Lange and Cannon-Bard theories of emotions and an example that supports each

A

?

48
Q

Define working memory

A

Limited capacity store for retaining information over the short term and for performing mental operations on the contents of this store

49
Q

What is neurogenesis and how has it been demonstrated in birds?

A

Neurogenesis is when new neurons are born. In birds labeled thymidine was incorporated into dividing DNA and have shown neurogenesis in relationship to periods of increased song.

50
Q

Patients with prefrontal damage show impairment in what type of memory?

A

Working memory

51
Q

____ is the rhythm, intonation, and pattern of sounds in language.

A

prosody

52
Q

What is orthography and how does its acquisition differ from spoken and written language?

A

Orthography is written and reading of a language. It differs from spoken language in that it requires instruction to master.

53
Q

Elizabeth Loftus studied the misinformation effect. Describe this effect and give an example.

A

Its when people alter their memory of an event after being asked a misleading question. Like for example they asked people “what color was the yield sign.” Even though the sign was a stop sign they will recall a yield sign

54
Q

The lateral prefrontal cortex and frontal pole support what type of behavior?

A

?

55
Q

Define sensitization

A

Increase in response with repeated presentations of a stimulus.

56
Q

What are the 3 components to successfully execute and action plan (from Ch 13 in your text)?

A
  • one must identify the goal and develop subgoals.
  • choosing among goals, consequences must be anticipated,
  • must determine what is required to achieve the subgoals.
57
Q

What thalamic nucleus is believed to play a role in guiding attention?

A

pulvinar

58
Q

Having to do with attention, Wurtz et al. made an observation that neurons in the parietal cortex fired before the saccade to the target occurred. What is a saccade and why would the neuronal response occur before the saccade?

A

Saccade is the fast movement of a body part, in this case the eyes of the monkey. A neural response could occur before a saccade because the neurons could be firing to activate the saccades or it could mean that the attention of the monkey was diverted to the target before anything else

59
Q

Most nonrighthanded people are left-hemisphere dominant. True or False?

A

true

60
Q

What is unconscious emotion and how was it demonstrated?

A

Its emotion we are not conscious of; they do not give us feelings but can still influence our decisions. It is demonstrated by subliminally induced affective reactions that still influence peoples preference judgments and even the amount of beverage they consumed without feeling any emotions.

61
Q

What area of the brain is primarily involved in cognitive control?

A

prefrontal cortex
