1
Q

Attention

A

It is the mechanism that we use to select for further in-depth neural processing items that are of most interest to us.

Q

Attention

A

Does not only select external sensory items of interest to receive further processing, but also internal thoughts and memories.

Q

Attention Bias

A

A tendency to preferentially focus on certain types of stimuli.

Humans have a natural bias towards faces, especially emotional ones. This bias can be exaggerated in individuals with mental health conditions like anxiety and depression.

Q

Negative Attentional Bias

A

The tendency to preferentially focus on negative information or stimuli while overlooking or downplaying positive or neutral information.

Cognitive bias that directs attention toward threats, errors, or negative outcomes.

Q

What Grabs Our Attention?

A

1) Salient Stimuli (loud, bright, sudden) - helps us identify potential danger/threats
2) Novelty (new or unexpected) - we’re always curious and seeking new info
3) Motion (moving or changing objects)

Q

Exogenous Attention (bottom-up/automatic)

A

The automatic allocation of your attention based on the
properties of the stimuli themselves.

Q

Endogenous Attention (top-down/intentional)

A

Not automatic, but instead is the allocation of
attention to items that you’ve chosen to pay attention to.

Q

Preattentive Processing

A

It’s the initial stage of perception where our brains rapidly take in sensory data and extract basic features like color, shape, orientation, and motion.

Q

Pop Out Search (Feature Search)

A

The target differs from distractors by one fundamental dimension (i.e., colour, shape, size).

A search based on a single distinctive feature of the target

Q

Conjunction Search (Serial Search)

A

The target shares features with distractors, requiring a more detailed search.

16
Q

What happens to items we don’t pay attention to?

A

They are filtered out

17
Q

Inattentional Blindness (Mack & Rock)

A

When we don’t pay attention, can be effectively blind even to salient visual stimuli.

18
Q

Inattentional Blindness

A

The failure to notice a clearly visible object because attention is focused elsewhere.

19
Q

Sustained Attention

A

Paying attention to the same item for a sustained period of time.

20
Q

Tactile

A

Sense of touch

21
Q

Right Parietal Cortex

A

Has a crucial role in sustaining attention across time.

Involved in spatial processing, alertness, distraction inhibition, and sensory integration.

22
Q

Visual Spatial Neglect

A

The syndrome that results from right parietal damage.

Patients suffering from such neglect one whole side of the world and they act as if it no longer exists.

23
Q

Attention and Awareness

A

If you lose the ability to pay attention you lose the ability to be aware of those things too.

24
Q

Contralesional

A

Opposite side of the brain lesion

25
Q

Ipsilesional

A

Same side of the brain lesion

26
Q

Bisection Task

A

Patients are presented with horizontal lines and asked to bisect the line - that is mark the middle of the line.

27
Q

Cancellation Task

A

Patients are asked to cancel out all of one type of stimuli.

28
Q

Representational Neglect

A

The inability to attend to mental images on the neglected side of space, despite intact memory for those details.

29
Q

Implicit Processing

A

Refers to the unconscious or unintentional influence of information on thought and behavior.

It occurs without conscious awareness or deliberate effort.

30
Q

Implicit Detection of Thread

A

When emotionally threatening stimuli are presented on the neglected side there is some residual processing.

31
Q

Extinction

A

A milder form of neglect where patients can detect stimuli on the neglected side when presented alone but fail to detect them when presented simultaneously with stimuli on the attended side.

32
Q

Threatening Stimuli

A

Can bypass conscious awareness and be implicitly processed in neglect patients.

33
Q

Emotional Salience

A

A measure of how much an event or piece of information captures our attention and evokes an emotional response.

34
Q

Attention

A

A cognitive process that allows us to selectively focus on specific information while filtering out irrelevant stimuli.

35
Q

Selection

A

The process of focusing on specific information from the environment or internal thoughts and memories.

It involves choosing what to attend to and what to ignore.

36
Q

Awareness

A

The state of being conscious or having knowledge of something.

It encompasses a wide range of mental states, from being fully alert and attentive to a vague sense of something.

37
Q

Conscious Awareness

A

A state of being fully alert and aware of one’s surroundings and internal thoughts.

It involves active processing and understanding of information.

38
Q

Residual Processing

A

The continued processing of information, often below the level of conscious awareness.

It refers to the idea that some information may be processed even when we are not consciously attending to it.
