1 second

Question 26

T or F: According to the modal model, most of the info in sensory memory is attended but it is lost quickly

Answer 26

false - most is unattended (we can't attend to everything happening around us), so it is lost quickly if most sensory memory was attended, we'd be a helluva lot smarter, and wouldn't be prone to errors during eyewitness testimony, etc.

Answer 39

b. the persistence of vision retains multiple positions of lights as they move through space sensory memory's refresh rate can create this illusion

Question 40

Sperling (1960) provided subjects with up to 12 pieces of information (e.g., letters) and asked them to recall all that they saw. Subjects were typically able to recall nearly _% of the information

Answer 40

40%

Question 41

Sperling (1960) conducted a series of well-known experiments in which participants were presented stimuli consisting of three rows of letters. In the whole-report condition, participants were presented with a grid of letters for a duration of between 15 and 500 milliseconds and were asked to report as many of the letters from the grid as they could. What Sperling found was that participants typically reported the letters from one of the rows, suggesting that the row that was available to report was based on...

Answer 41

which one they were paying attention to / attending

Question 42

The ability to report the letters in Sperling's rows of letters experiment, a behavioural output, depends on those items making their way into ... using attention

Answer 42

into STM

Question 43

Sperling referred to a high-capacity/short-duration form of visual memory as _ memory

Answer 43

iconic memory based on the fact that the memory is something like a photographic image or icon; if you have photographic memory, it is likely to be of high capacity (high yield, etc.), but may not necessarily last very long

Question 44

Other experiments using sound to remember, rather than Sperling's letter grids, suggest that there is also an auditory form of sensory memory, called _ memory

Answer 44

echoic "Hello......hello....helllo...!"

Question 45

T or F: there are only two types of sensory memory

Answer 45

false - there may be more, but they are difficult to research experimentally there may be tactile memory, even taste, but it's hard to capture sensory vs short-term. But you can certainly remember tastes, textures, etc.

Question 46

What is the duration of iconic memory? a. 30 seconds b. 1 second c. 1 minute d. 5 - 6 seconds

Answer 46

b. 1 second Sperling's partial report method illustrated that subject performance quickly decayed if there was a delay between stimulus exposure and the cue-tone it is still a form of sensory memory, so it's likely just as long - 1 second

Question 47

According to the modal model of memory, ...'s function is to hold information in place until it can be used for some behavioral task (such as entering the name of a website you just heard about), transferring information into LTM, or maintaining the information through rehearsal.

Answer 47

STM

Question 48

In the auditory domain (e.g., remembering a list of numbers or names), it is generally agreed that STM can hold an average of _ items. In the visual domain it is agreed (not as unanimously) that it can hold around _ items. This suggests that the auditory domain is more stable than the visual domain.

Answer 48

seven; four auditory info seems to be more stable than visual

Question 49

Miller calls the capacity limit to remember items as "The magical number _ plus or minus _"

Answer 49

seven; two

Question 50

Research has found that a person’s capacity to remember quantities of info remains stable across multiple tests, and even over many years, and thus appears to be a fixed feature of a person’s brain. Those who can remember a lot are considered _-_, and those who cannot are considered of _-_

Answer 50

high-capacity (up to 9) low-capacity (down to 5)

Question 51

We can remember in STM meaningful information by way of _, whether letters, numbers or sounds that constitute a meaningful whole

Answer 51

chunks

Question 52

The capacity to chunk info into larger units depends on engaging _TM

Answer 52

LTM, where patterns of previously encountered items are stored that's why chess players have better memory when presented with items on a chessboard; they can utilize their LTM to remember where items are, as opposed to novices who may not be familiar with particular plays, etc.

Question 53

T or F: According to Miller, once a combo of items is matched to memory, it needs to be represented as separate items

Answer 53

false if it's already matched in chunks, why repeat work? it's already applied and encoded

Question 54

A capacity limit has been found for _ STM (_STM)

Answer 54

visual STM (VSTM) we can only remember so many details from someone walking down the street; it is only the attended ones that are remembered, of which there are still less that are usually remembered (3 to 5)

Question 55

VSTM (visual short-term memory) is typically measured using a _-detection task

Answer 55

change

Question 56

In Luck and Vogel's 1997 study, they had participants presented with a screen with several objects, such as colored squares. This screen disappears and a new one is shown, which may be identical to the original or have some property changed. When the number of items in the set is less than 4, performance is nearly perfect but after four items, it begins to decline rapidly with the number of items in the set. Using this kind of task, researchers have concluded that _ has a capacity of three to five items

Answer 56

VSTM

Question 57

Luck and Vogel (1997) established the visual short term memory (VSTM) as having a capacity of _ to _ items

Answer 57

3 to 5

Question 58

Luck and Vogel (1997) used a paradigm reminiscent of _ _ in order to test visual memory. Once the number of objects increased to greater than five, memory performance rapidly dropped off

Answer 58

change blindness

Question 59

In the case of visual stimuli, people can remember _ visual objects, even if each object has multiple features, such as a shape, a colour, and an orientation. In this case, remembering four objects would consist of remembering 12 features (Wheeler & Treisman, 2002)

Answer 59

4 visual objects; 12 features (3 features per object - 3 x 4 = 12)

Question 60

Inoue and Matsuzawa (2007) provided chimpanzees and human participants with five digits that appeared on a screen from 210 milliseconds up to 650 milliseconds. After that wait period, the digits disappeared and were replaced by blank squares. The subject (whether human or chimp) was tasked with... to reveal the digits in numerical order.

Answer 60

touching the squares

Question 61

Inoue and Matsuzawa (2007) provided chimpanzees and human participants with five digits that appeared on a screen from 210 milliseconds up to 650 milliseconds. After that wait period, the digits disappeared and were replaced by blank squares. The subject (whether human or chimp) was tasked with touching the squares to reveal the digits in numerical order. On average, most humans' memory performance for the five digits decreased when the presentation time dipped below 400 milliseconds. However, some chimpanzees were ...

Question 70

Without any distractions, people are able to engage in _ _, the repetition of information in STM which essentially reactivates the initial encoding

Answer 70

maintenance rehearsal

Question 71

Information can theoretically persist in STM for as long as you can keep _

Answer 71

rehearsing this is dependent on not having anything else to spend time on, but there are typically some things happening in the environment that would affect STM, let alone thoughts or emotions....etc

Question 72

Answer 72

counting backward by threes out loud.

Question 73

The Brown-Peterson task consisted of an STM task in which participants were told, on each experimental trial, to memorize 3 letters, after which were presented with a 2-digit number and had to begin counting backward by threes out loud, a task that was intended to prevent _ of the trigram. After a certain duration of counting backward, participants had to report their memory of the trigram.

Answer 73

rehearsal

Question 74

Answer 76

y-axis; x-axis Peterson and Peterson (1959) found that as the time interval increased, participants were less successful at recalling even small amounts of information.

Question 77

According to _ models, forgetting occurs simply because of the passage of time

Answer 77

decaying memory is thought of like a leaky bucket in which info trickles out

Question 78

One of the possible causes of forgetting is _, in which new info that comes into memory serves to displace older info

Answer 78

interference

Question 79

_ interference refers to cases in which learned info causes you to forget something that you learn in the future

Answer 79

proactive refers to the item in the future that is forgotten

Answer 81

proactive

Question 82

If studying for biology later on causes you to forget what you read here, you would experience _ interference

Answer 82

retroactive refers to the item in the past that is forgotten

Question 83

Peterson and Peterson's (1959) experiment showing fading memory of people doing a visual task with rehearsal suppression due to _, not interference, based on the fact that participants were not asked to remember anything else besides the letters on each trial

Answer 83

decay

Question 84

Although it is said to be due to decay, the reason for forgetting in the Brown-Peterson task may be due to interference from _TM to the _TM; specifically, as participants performed multiple trials over the course of the experiment, it is possible that some of the letters from previous trials could interfere (proactively) with the current trial

Answer 84

LTM to STM if it happened quite a few min ago, then it would be LTM, not STM or a different type of memory

Question 85

Keppel and Underwood (1962) redid the Brown-Peterson task and found that in the first few trials, participants remembered the trigram for up to 15 seconds with relatively high accuracy. Only on later trials, after participants had seen many previous trigrams...

Answer 85

did decay over time begin to appear, with items remembered at a reduced accuracy

Question 86

Lewandowsky et al. (2004) used the _ _ technique to prevent rehearsal without causing interference in STM with a new item to remember

Answer 86

articulatory suppression

Question 87

Lewandowsky et al. (2004) had participants report remembered sequences of letters by responding on a computer keyboard. They had participants type the sequence at varying speeds, so they could measure the effect of time on recall. Overall, they found that there was A/NO effect of the speed at which participants had to repeat the letters on their recall of the items. They concluded that the passage of time alone, without interference, does not cause decay in STM

Answer 87

NO

Question 88

Based on the evidence discussed in the two studies above, which of these is the most supported explanation for why forgetting occurs in short-term memory? a. interference b. decay c. a combo of interference and decay d. neither decay nor interference

Answer 88

c. a combo of interference and decay

Question 89

Stewart is a senior in high school and has had to change his school email account each year. As he is entering his new password, he keeps getting an error message because the password is wrong. It turns out that he keeps entering his freshman year password. His inability to remember his newest password in this example is due to ______. a. proactive interference b. retroactive interference c. a combo of retroactive and proactive interference d. none of the above (it depends on whether the new password has been rehearsed)

Answer 89

a. proactive interference Older information ("Material A") is interfering with newer information ("Material B"). Interference focuses on the information that is being disrupted

Question 90

Would the sensory memory (not short-term memory) of chess experts be better than that of non-experts for chess piece configurations, and why? a. no, bc they can only chunk info that is processed in STM, not sensory memory b. no, bc they can only rehearse info in STM, not sensory memory c. yes, bc they can chunk info by sending it to LTM d. yes, bc they can rehearse info in sensory memory

Answer 90

a. no, bc they can only chunk info that is processed in STM, not sensory memory Trick question!

Answer 92

three

Question 93

The visual component of WM is the _-_ _

Answer 93

visuo-spatial sketchpad

Question 94

The visuo-spatial sketchpad can be used to analyze and manipulate visual info such as mentally rotating a remembered object. This is/not similar to the original conception of VSTM

Answer 94

is not visual STM is based on the item a it appears, not any rotation, etc. of it

Question 95

The 3 components of WM are: visuo-spatial sketchpad phonological loop _ _

Answer 95

central executive

Question 96

THe _ _ is the auditory component of WM. It allows auditory info to be repeated so that it may be used or analyzed.

Answer 96

phonological loop

Question 97

THe phonological loop is the auditory component of WM. It allows auditory info to be repeated so that it may be used or analyzed. It is/not similar to the original conception of STM

Answer 97

IT IS SIMILAR

Question 98

A component that is completely novel to the WM model is _ _: a gatekeeper that determines what info makes it into working memory.

Answer 98

central executive

Question 99

The_ _ toggles between the visual and auditory memory stores, as a component of the Baddeley's WM, therefore it is placed in the middle of the diagram, coordinating with visual and auditory info by way of the visuo-spatial sketchpad and the phonological loop

Answer 99

central executive

Question 100

Replaying verbal information in your mind is considered to be distinct from visually imagining, or _, information

Answer 100

storing

Question 101

The properties of working memory are stored in terms of its distinct sensory codes (i.e., ...)

Answer 101

auditory working memory is remembered in terms of how it was remembered auditorially (e.g., pitch, tone, etc.)

Question 102

The critical aspect of WM is that it requires _ observation

Answer 102

introspective; what you remember has properties pertaining to the sense used: listening you remember pitch, intonation, etc.

Question 103

Brooks (1968) illustrated how subjects completed memory tasks primarily taxing either the phonological loop or visuo-spatial sketchpad and then used either an auditory or visual mode to respond. He found that people did better on the task when they had to respond in a _ modality than in the one initially used

Answer 103

different!

Question 104

Brooks (1968) illustrated how subjects completed memory tasks primarily taxing either the phonological loop or visuo-spatial sketchpad and then used either an auditory or visual mode to respond. He found that people did better on the task when they had to respond in a different modality than what they had to remember. These results suggest that visual and auditory memory are processed _, and they do/not interfere with one another

Answer 104

SEPARATELY; DO NOT INTERFERE remember, this is what this particular study had shown, rather than what later research has since found

Question 105

Conrad (1974) found that participants confused letters that ______ to each other when performing a free recall task. a. sound similar b. look similar c. sound different d. look different

Answer 105

a. sound similar This is an error due to auditory info free recall is an AUDITORY task, so it would make sense that it would be auditory info used, and when they sound similar they would do worse note that if they were using a different sense, then it would be visual, which should show more effective recall, particularly when they look different

Question 106

Vogel et al. (2005) compared the ability of individuals with high and low short-term memory capacity to be able to select relevant items for memory and filter out irrelevant distractors. The cue's direction indicated which side of the display (left or right) participants had to remember, then they were presented with a memory display, consisting of several coloured triangles, either 2 blue triangles (of blue and red) or 4 blue triangles. They were asked to see if a later test display looked similar to the initial image. They also had to use an EEG to measure event-related potential response known to be active during STM activation. What did the test show (re: EEG)?

Answer 106

a stronger ERP response was shown for FOUR blue rectangles represented than two blue rectangles represented (this effect would be across individuals - between-subjects, regardless of memory capacity group)

Question 107

Vogel et al. (2005) compared the ability of individuals with high and low short-term memory capacity to be able to select relevant items for memory and filter out irrelevant distractors. The cue's direction indicated which side of the display (left or right) participants had to remember, then they were presented with a memory display, consisting of several coloured triangles, either 2 blue triangles (of blue and red) or 4 blue triangles (8 total). They were asked to see if a later test display looked similar to the initial image. They also had to use an EEG to measure event-related potential response known to be active during STM activation. What did researchers find (re: EEG) when the participants were asked to ignore the red triangles and only pay attention to 2 blue triangles (4 total)?

Answer 107

low-STM individuals used much higher ERP response since they forgot that they should be looking for 2, not 4, than high-STM individuals who had a low ERP (remembered the new instructions; filtered out the distracters)

Question 108

Vogel et al. (2005) compared the ability of individuals with high and low short-term memory capacity to be able to select relevant items for memory and filter out irrelevant distractors. The cue's direction indicated which side of the display (left or right) participants had to remember, then they were presented with a memory display, consisting of several coloured triangles, either 2 blue triangles (of blue and red) or 4 blue triangles (8 total). They were asked to see if a later test display looked similar to the initial image. They also had to use an EEG to measure event-related potential response known to be active during STM activation. What did they determine would be the cause of low ERP response in high-STM individuals for the task asking to only pay attention to 2 blue (when presented with 4 triangles total)?

Answer 108

any distractions would be due to an issue with the central executive; high-STM individuals would have filtered that through. Likely an issue with central executive, perhaps not memory decline but an inability to work at such a high capacity

Question 109

Vogel, McCollough, and Machizawa (2005) demonstrated that individuals with high short-term memory capacity ______. a. are better at paying attention to irrelevant info but experience a trade-off in executive processing b. can better track multiple moving objects and therefore have a higher performing memory c. are negatively correlated with central executive processing abilities d. are better at focusing on relevant info and filtering irrelevant info

Answer 109

d. are better at focusing on relevant info and filtering irrelevant info Higher STM memory capacity helped improve subjects' performance

Question 110

Which of the following is one job of the central executive, according to the working memory model? a. attach meaning to incoming info b. activate relevant associations for new info to make it easier to remember c. replay verbal info in your mind to help you remember that auditory info d. coordinate between the visuo-spatial sketchpad and phonological loop

Answer 110

d. coordinate between the visuo-spatial sketchpad and phonological loop It is the central store, working as the "boss" answer "a. attach meaning to incoming info" is tricky bc although the central executive is filtering for relevant info, it isn't attaching meaning; it's filtering for relevant meaning, but not making any assumptions about it. Trick question!

Question 111

Baddeley's WM received criticism for not incorporating memory when it forms a compelling and ..., a phenomenon related to Miller's chunking.

Answer 111

coherent story; this explains why the memory palace is such an effective mechanism for memory

Answer 114

episodic buffer

Question 115

Based on criticism of Baddeley's initial WM model, he updated it with a new component called the episodic buffer: a separate, time-limited, memory store that can combine info from across different sources, including the phonological loop, the visuo-spatial sketchpad and _

Answer 115

long-term memory

Question 116
