Study Notes

Attention

Attention is the focusing of consciousness, taking possession of the mind with one object or thought.
Attention can be categorized as top-down (goal-directed) or bottom-up (stimulus-driven).
Goal-directed attention is controlled by the individual based on their goals and expectations.
Stimulus-driven attention is triggered by unexpected and important stimuli.

Attentional Systems in the Brain

A goal-directed system (top-down) is influenced by expectations, knowledge, and current goals.
A stimulus-driven system (bottom-up) is activated by sudden and potentially important stimuli.
The stimulus-driven system acts as a "circuit-breaker," redirecting attention.

Auditory Selective Attention

Studies using dichotic listening and shadowing demonstrated poor recall of information from the unattended ear.
Listeners use physical cues (e.g., gender, voice features) to maintain attention.
Theories of auditory selective attention:
- Early Selection Theory (Broadbent): Input is briefly held in a sensory buffer and quickly lost unless attended to.
- Attenuation Theory (Treisman): Processing begins with physical properties and extends to meaning, depending on available processing capacity.
- Late Selection Theory (Deutsch & Deutsch): All stimuli are fully analyzed, but the most relevant to the task is reported.
Factors influencing auditory attention:
- Bottom-up: Temporal coherence, location of auditory signal.
- Top-down: Familiarity with speaker, expectations about meaning, integration of visual information.

Posner (1980) Cueing Task

Participants were faster at responding to targets in cued locations than uncued locations.
This task demonstrates:
- Orienting attention: Time taken to move attention from a neutral to a task-relevant point.
- Disengaging attention: Time taken to disengage attention from an irrelevant location before moving to a relevant one.

Visual Selective Attention

Visual attention operates like a spotlight, focusing on a small area.
Visual attention is also like a zoom lens, which can be adjusted to increase or decrease the size of the attended region.
Visual attention can be split across multiple regions of space (e.g., attending to 5 different regions).
Evidence exists for object-based attention, in addition to spatial-based attention.

Multitasking: Real World Implications

Multitasking is defined as performing two or more tasks simultaneously, dividing attention among them.
Multitasking can have detrimental effects on performance, even if it feels efficient.
Examples of Multitasking:
- Distracted driving
- Texting while walking
- Working on other tasks while in class.
Multitasking leads to poorer performance due to divided attentional resources.

Visual Search : Real World Implications

Visual search is the process of finding a specific target among distractors.
Real-world examples: Airport security, medical imaging, finding friends, shopping.
Guided search model (Wolfe, 2021):
- Attention binds features together to create recognizable objects.
- Attention guides search to process information efficiently, creating a dynamic "priority map".
"Pop-out" effect: Salient single features (e.g., color) can be detected in parallel.
When multiple features are needed, attention is needed to bind them, which is resource-intensive and serial.

Distraction

Even unattended stimuli receive some processing.
We can be distracted by both external (salient stimuli) and internal (random thoughts) stimuli.
Distractibility is influenced by:
- Features of the stimuli
- Situational factors
- Individual differences.

Misdirection

Attention can be manipulated, as demonstrated by pickpockets and magicians.
Misdirection is used for various purposes:
- Selling products
- Spreading misinformation
- Creating suspense in movies.
