Study Notes
Attention
- Mechanism for actively processing limited information from vast sensory input and cognitive processes.
- Outcomes when detecting target stimuli: hits, false alarms, misses, correct rejections.
Four Main Functions of Attention
- Signal Detection and Vigilance: Focus on identifying specific stimuli amidst distractions.
- Search: Engaging actively in looking for particular stimuli.
- Selective Attention: Choosing specific stimuli to focus on while ignoring others.
- Divided Attention: Managing multiple tasks simultaneously by allocating attentional resources efficiently.
Signal Detection Theory
- Framework explaining how people identify important stimuli from distractions.
Selective Attention
- Cocktail Party Effect: Focusing on one conversation amid several others.
- Shadowing: Listening to and processing two different messages simultaneously via dichotic presentation.
Theories of Selective Attention
- Attenuation Model (Anne Treisman): Suggests weak filtering of non-target stimuli rather than complete blockage, allowing some unattended information analysis.
- Broadbent's Model: Early filtering at sensory input level based on physical properties (e.g., loudness, pitch) before reaching perception.
- Late-Filter Model (Deutsch and Deutsch): Filters stimuli after analysis of both physical properties and meaning, allowing additional processing before selection.
Factors Influencing Attention
- Anxiety: Can decrease attention span and focus.
- Arousal: Levels of alertness affect attentional capacity.
- Task Difficulty: More complex tasks demand greater focus and resources.
- Skill: Higher proficiency can improve attention management.
Spatial Neglect
- Attentional dysfunction resulting in ignoring half of the visual field opposite the brain hemisphere with damage (common in right hemisphere lesions).
Attention-Deficit/Hyperactivity Disorder (ADHD)
- Factors contributing to ADHD: maternal substance use during pregnancy, lead exposure, brain injury, food additives, dopamine regulation disparities.
- Symptoms in inattentive ADHD type: easily distracted, careless mistakes, incomplete task completion, and tendency to misplace necessary items.
Automatic and Controlled Processes
- Automatic Processing: Task performance without conscious involvement, using predefined rules or algorithms.
- Controlled Processing: Conscious and intentional cognitive activities requiring focused attention.
Change Blindness
- Inability to notice changes in objects or scenes being observed, highlighting limitations in visual attention.
