Q

Concepts required by Signal Detection Theory (SDT)

A
  1. attention—paying enough attention to perceive objects that are there
  2. perception—perceiving faint signals that may or may not be beyond your perceptual range
  3. memory—indicating whether you have/have not been exposed to a stimulus before

23
Q

The part of the brain that appears to be an important brain structure in the regulation of vigilance.

A

Amygdala

24
Q

Refers to a scan of the environment for particular features—actively looking for something when you are not sure where it will appear

A

Search

25
Q

These are non target stimuli that divert attention away from the target stimulus and make search more difficult.

A

Distracters

26
Q

Two types of search

A
  1. Feature Search
  2. Conjunctive Search
27
Q

A type of search where we simply scan the environment for that feature, and where distracters play little role in slowing our search.

A

Feature Search

28
Q

A type of search where we look for a particular
combination of features.

A

Conjunctive Search

29
Q

This theory offers a distinction between feature and conjunctive- searches. Feature search is defined by a single feature and no attention is required, while conjunctive search defined by two features: shape and color, thus, attention is required.

A

Treisman’s Feature Integration Theory (FIT)

30
Q

This theory argues that similarity between targets and distracters is what is important, not the number of features to be combined. Thus, the more shared features among items in display, the more difficult to detect a particular target.

A

Similarity Theory

31
Q

Two consecutive stages of Guided Search

A
  1. Parallel Stage
  2. Serial Stage
32
Q

A stage in Guided Search where the individual simultaneously activates a mental representation of all the potential targets.

A

Parallel Stage

33
Q

A stage in Guided Search where the individual sequentially evaluates each of the activated elements, according to the degree of activation.

A

Serial Stage

34
Q

Theories of Selective Attention

A
  1. Broadbent’s Model
  2. Treisman’s Attenuation Model
  3. Late-Filter Mode
35
Q

A theory of selective attention which suggests that stimuli is filtered at sensory level occurring after information goes through the sensory storage and that only one sensory channel is allowed to proceed to the working memory storage.

A

Broadbent’s Model

36
Q

A theory of selective attention which suggests that at least some information about unattended signals is being analyzed. She proposed a theory of selective attention that involves a later filtering mechanism.

A

Treisman’s Attenuation Model

37
Q

A theory of selective attention which suggests that the location of the filter is even later than Treisman’s Attenuation Model, and that stimuli are filtered out only after they have been analyzed for both their physical properties and their meaning. This later filtering would allow people to recognize information entering the unattended ear.

A

Late-Filter Model

38
Q

The two processes that govern attention according to Ulric Neisser

A
  1. Preattentive Process
  2. Attentive, Controlled Process
39
Q

A process governing attention where automatic processes are rapid and occur in parallel. They can be used to notice only physical sensory characteristics of the unattended message, but they do not discern meanings or relationships.

A

Preattentive Processes

40
Q

A process governing attention where processes occur later. They are executed serially and consume time and attentional resources, such as working memory.

A

Attentive, Controlled Process

41
Q

A type of simultaneous attention that allows us to process different information sources and successfully carry out multiple tasks at a time.

A

Divided Attention

42
Q

A theory of Divided Attention where either a single pool or a multiplicity of modality-specific pools may be involved.

A

Attentional-Resources Theory

43
Q

Four factors that influence ability to pay attention

A
  1. Anxiety (high anxiety = low attention)
  2. Arousal (tired or drowsy = low attention; excited or happy = high attention)
  3. Task Difficulty (influences performance during divided attention)
  4. Skills (more practiced or skilled = enhanced attention)
44
Q

A condition which symptoms are inattention, hyperactivity, and impulsivity.

A

Attention Deficit Hyperactivity Disorder (ADHD)

45
Q

A condition where there is an inability to detect changes in objects or scenes that are being viewed.

A

Change Blindness

46
Q

A phenomenon where people are not able to see things that are actually there, purely as a result of a lack of attention rather than any visual defects or deficits.

A

Inattentional Blindness

47
Q

A condition where there is lesion on one side of the brain, which causes a person to ignore half of their visual field that is contralateral to (on the opposite side of) the hemisphere of the brain that has a lesion. It is a result mainly of unilateral lesions in the parietal and frontal lobes, most often in the right hemisphere.

A

Spatial Neglect or Hemi-neglect

48
Q

The concept of attention carries two processes, namely Automatic Processes and Controlled Processes. Which process requires NO conscious control?

A

Automatic Process

49
Q

The concept of attention carries two processes, namely Automatic Processes and Controlled Processes. Which process requires conscious control?

A

Controlled Process

50
Q

Comprises only the narrower range of info that the individual is aware of manipulating.

A

Consciousness

51
Q

Which view of complex mental processes suggests that individuals have GOOD ACCESS to their complex mental processes (eg. chess, math computation problems)?

A

First View or Protocol Analysis

52
Q

Which view of complex mental processes suggests that individuals DO NOT HAVE A GOOD ACCESS to their complex mental processes (eg. deciding which model of a car to buy)?

A

Second View

53
Q

An example of preconscious processing where perception of targets stimuli is influenced or “primed” by previous stimuli.

A

Priming

54
Q

An example of preconscious processing where an individual tries to remember something that is stored in memory but cannot readily be retrieved.

A

Tip of the Tongue

55
Q

An example of preconscious processing where an individual cannot consciously see a certain portion of their visual field but still behave in some instances as if they can see it.

A

Blindsight
