Big percentage missed the fight/failed to notice (even more w night)
34
Implications of Chabris Eyewitness Experiment
Intentional Blindness
35
Intentional blindness
Failure to notice fully-visible but unexpected object because attention was engaged elsewhere
36
Chabris Eyewitness Experiment - Results (3)
They noticed less when:
1. At night
2. 2 counts
3. 1 count
- Even with 0 counts some still missed it
37
Intentional blindness according to Eyewitness results (3)
Increasing the effort required by primary task, descreases noticing unexpected events
38
Considering the experiments of selective attention, how good is it?
- Powerful: when really focused you miss information
- Inattentional blindness: you miss other things depending how demanding primary task is
39
Dichotic listening task
Requires the participant to shadow the message in one ear while ignoring the message in the other
40
What type of attention does a dichotic listening task primarily test?
Selective attention
41
Colin Cherry study
Dichotic listening task

2. Meaning does not get through
43
Colin Cherry study shows that attention is powerful BUT some...
Unattended information gets through
44
What research lead to the development of the Early Filter Model (Broadbent)?
Colin Cherry and other similar experiments
- Dichotic listening task + shadowing
45
Early filter model (Boradbent)
Argues that you can focus on one message only and information from the other one is not taken in
46
Stages of Early filter model of attention
1. Sensory memory
2. Filter
3. Detector
4. Output
47
Bottleneck model (Broadbent's model):
- The filter restricts info flow like a bottle neck
- BUT it also keeps out a large portion of info
- Info gets through based on specific physical characteristics (ex. pitch)
48
Why is the Early filter model also called Early selection model?
Because filter eliminates unattended info at the beginning of the flow of information
49
Two stages of processing in the Early Filter Model
1. Sensory registration
2. Filter
50
The Early Filter Model explains Colin Cherry's results because...
It indicates why the participant was able to recognize pitch and gender of the person speaking but not the meaning (it was filtered)
51
The Early Filter Model does not explain...
The Cocktail Party effect by Moray - why does our name not get filtered?
52
Moray's cocktail party effect
We notice our name embedded in an ignored auditory channel
53

C2: city name
54
GSR experiment by Cherry (Results)
1. No recognition of city words
2. Physical reaction to city names (elevated GSR)
55

Meaning of the word is processed in unattended channel but still no memory of the message
56
Evidence against Early Filtering Model (research)
1. Moray (cocktail effect)
2. Cherry (city names)
3. Dear Jane experiment
57
Evidence against Early Filtering Model (ideas)
Some unconscious processing of unattended message

63
MacKay study
- Ppts listen to ambiguous sentences in unattended.
- Later on presented with pairs of sentences linked to ambiguous scenes (identify which was closest in meaning to what they had previously heard)
64

67
Stages of Late Filtering model
1. Detection
2. Recognition
3. Filter
68
Why was the Late selection model proposed?
Because of experiments showing that messages can be selected at a later stage of processing - based on their meaning
- MacKay
69
Late Selection model: most of the information is processed to the level of ... before being selected for extended analysis and inclusion in the decision making processes
meaning
70
Load Theory of attention (2 elements)
1. Processing capacity
2. Task load (primary task difficulty and distractor difficulty)
71
Load theory of Attention by Goldstein
The ability to ignore task-irrelevant stimuli is a function of not only the load of the task you are trying to do, but also how powerful the task-irrelevant stimulus is
72
Load theory of Attention by Goldstein (Implications)
a. Low-load tasks: few cognitive resources may leave resources available for processing unattended task-irrelevant stimuli, whereas;
b. High-load tasks: use all a person's cognitive resources don't leave any resources to process unattended task irrelevant stimuli
73
Foster and Lavie
- Load theory
Focus on a specific location or a particular stimulus, while simultaneously a distracting stimulus presented close to the attended location or field.
- Degree of distraction is measured by comparing reaction times between 2 or 3 different conditions
74
Foster and Lavie (Results)
Found that there is an interaction between task difficulty and distractor. Specifically, participants were more distracted by distractor in the easy task compared to the hard task
75
Overt shift of attention
When a person redirects their focus to something by physically moving their eyes
76
Covert shift of attention
Shift in their focus mentally without making any visible movements

How to increase interest?
Increase visibility of brand: if brand is powerful, simply have to ensure visibility. This will increase attention due to interest.
84
How to increase intrigue?
Develop a plot line: create suspense and mystery. Build a story that unfolds over time. Will increase interest and motivation.
85
How to increase competition?
Develop a competition: generate participation and create competition. Gamify the process and will increase interest and motivation
86
How to increase humor?
Make them laugh: we inherently want to be in a good mood. When advertisements generate positivity and humor, we will pay attention
87
What are 4 components that help engage customers when promoting an ad or brand?
1. Interest
2. Competition
3. Humor
4. Intrigue
88
Treisman's Feature-Integration Theory (2 processes)
1. Feature search
2. Conjunction search
89
Feature search
- Automatic
- Fast, pop-out
- Independent of number of distractors
90
Conjunction search
- Controlled
- Slow, effortful, needs "glue"
- Depends on number of distractors
91
Treisman's Feature-Integration Theory (broken down into 3)
1. Feature maps
2. Automatic processing
3. Master map and attention
92
Feature maps
Your brain first breaks down objects into basic features like color, shape, and motion using feature maps
93
Automatic processing
Recognizing the features and breaking them down happens automatically and in parallel
94
Master map and attention
Attention acts as "glue" that binds these features together, allowing you to recognize the object as a whole.
95
Treisman and Schmidt experiment of illusory conjunctions
4 objects and 2 black numbers showed briefly. Participants then told to report what they had seen.
96
Treisman and Schmidt experiment of illusory conjunctions (Results)
Participants reported seeing objects that were made up of a combination of features from two different stimuli
97
Illusory conjunctions
Combinations of features from different stimuli
98
According to Treisman, illusory conjunctions occur because...
in the pre-attentive stage, features exist independently from others. As such, they can be incorrectly combined if there is more than one object and they have limited time to see it.
99
Treisman and Schmidt experiment of illusory conjunctions: preattentive and focused stage
1. Preattentive: features of objects are processed automatically and in parallel across the visual field
2. Focus: attention plays a crucial role in "gluing" these features together to form a coherent perception of an object. Require focus attention
100
(Left) Hemispatial neglect
A neuropsychological deficit of attention
- Damage to right parietal lobe (typically)
- Impairments in attention to the left visual field (typically)
101
Left neglect
Difficulty disengaging attention from right side of space
102
Examples of neglect
- Visual search
- Spontaneous writing
- Reading
- Line-bisection task
103
Right Hemispatial Neglect
- Unawareness of the left side
- More severe and slower recovery
- Longer lasting
104
Left Hemisphere Neglect
- Affects attention to the right
- Less severe and faster recovery
- Shorter lasting
105
Left Hemispatial neglect - Hypothesis 1
Right parietal lobe manages spatial awareness on both sides, whereas left parietal specialized for language
106
Left Hemispatial neglect - Hypothesis 2
Related to sleep and suppressing regions involved in hemispatial neglect
107
Divided attention
The distribution of attention among 2+ tasks
108

1. silence
2. white noise
3. auditory distraction
114
Wais coffee shop/music experiment (Results)
Silence is the most efficient
115
Multitasking
Switching attention between tasks. You have to do this when the tasks are not automatic, or specifically in higher load situations
116
How does multitasking affect learning?
1. Assignment takes longer
2. Mental fatigues leads to more mistakes
3. Remember encoding info less
4. Harder to apply knowledge to other things
117

123
Relevant emotions for orienting attention
- Surprise/startle
- Negative/positive emotions
124
Orienting attention definition
An automatic shift in attention: unconscious, uncontrollable, immediate, powerful
125
How does orienting attention work?
- Something makes you shift your attention
- You process new info and shift back
- Very brief process
126
Central vision
The area you are looking at
127
Peripheral vision
Everything off to the side
128
Preattentive processing
The continuous processing of the environment outside the focus of your attention (in the periphery)
129
Teisman's feature-integration theory
The theory focuses on how we combine different features like color, shape, size, and orientation into a unified perception of an object.
130
Preattentive processing limitations
Limited informational capture
131
Is controlled attention endogenous or exogenous?
endogenous
132
Is automatic attention endogenous or exogenous?
Exogenous
133
Bottleneck theory
People have limited cognitive resources. Thus, information and stimuli are filtered or 'selected' for resulting in only a subset of information being processed at any one time
134
Biased competition theory
When one unattended object falls into a neuron's receptive field it increases the neuronal firing. However, adding one or more unattended objects has the opposite effect, it reduces neuronal firing.
135
We have an attentional bias towards...
emotional stimuli
136
The imapact of emotion on attention depends on...
1. type: arousal and valence
2. time-course: early processing versus later processing
137
Cueing paradigm/dot probe task
Pairs of neutral-emotional stimuli presented first and are followed by a neutral target. Speed of target identification
138
Cueing paradigm/dot probe task (Results)
When emotional material is threatening and/or biologically relevant and delivered quickly there is a speeded processing for targets presented in this location
139
Attentional blink study
Participants see rapid picture stream with some target pictures. Participants typically missed targets that followed a previous target
140
Visual search paradigm
Pictures (distractors) + picture of deviant (snake).
Easier to find fear picture with distractors
141
Visual search paradigm
Faster detecting angry face in serious faces
142
Experiment about negative and positive images
- Attention is first captured by negative pictures only but then it remains captured by negative and positive
143
Two different types of effects of emotion on attention according to Barbara Fredrickson
1. Positive: Broaden and build
2. Negative: narrow and reduce
144
Positive emotion broaden (characteristics)
- Better memory for details
- See more possibilities
- More creative
- More trust
145
Negative emotion narrows characteristics
- Narrows attention
- Negative interpretations
- Favors habitual routines
- Leads to rumination
146
Emotional stroop paradigm
Slowing of reaction times to name the colors of negative emotional words in contrast to naming the color of neutral words
147
Debate: Nature of emotions
Categorical vs dimensional
148
Debate: What is emotion
Universal vs constructed
149
Universal view of emotions
There is a set of universal emotions. These emotions and their physical expressions are biologically innate and evolutionary adaptive. EKMAN
150
Basic emotions theory by Ekman
1. Facial expressions are a window to emotions
2. Expression of certain emotions is universal
151
Basic Emotions theory: Evidence in support
- Darwin
- Tomkins and McCarter
- Universality studies
152
Constructivist approach
Emotions do emerge from biological processes but they also emerge from information processing, social interaction, and cultural contexts.
