Study Notes
Attention Overview
- Attention is the process of actively filtering a limited amount of information from a larger pool of sensory input, stored memories, and cognitive processes.
- Detecting target stimuli results in four outcomes: Hits, False Alarms, Misses, and Correct Rejections.
Four Main Functions of Attention
- Signal Detection and Vigilance: The ability to detect specific stimuli within a range of distractions.
- Search: An active effort to find a particular stimulus in the environment, often complicated by distractors.
- Selective Attention: The choice to focus on certain stimuli while ignoring others; exemplified by the Cocktail Party Effect, where individuals concentrate on a single conversation amidst a backdrop of noise.
- Divided Attention: The ability to perform multiple tasks simultaneously by allocating attention wisely among them.
Theories of Selective Attention
- Signal-detection Theory: A framework explaining how important stimuli are identified in the presence of distractions.
- Broadbent's Model: Proposes a filter at the sensory level, allowing only one channel of sensory information to be processed while blocking out others.
- Attenuation Model (Anne Treisman): Suggests that instead of completely blocking irrelevant stimuli, attention weakens their influence.
- Late-Filter Model (Deutsch and Deutsch): Filters stimuli after their physical and semantic processing.
Factors Influencing Attention
- Anxiety: Heightened anxiety can impair attention and focus.
- Arousal: The level of alertness can greatly affect attention capacity.
- Task Difficulty: Challenging tasks may demand more focused attention.
- Skill Level: Proficiency in a task can enhance attentional efficiency.
Spatial Neglect
- A condition where individuals ignore one half of their visual field, typically due to right hemisphere brain damage, affecting awareness and attention.
Attention-Deficit/Hyperactivity Disorder (ADHD)
- Linked to maternal behaviors (smoking, drinking), lead exposure, brain injuries, and differences in brain circuitry involving dopamine.
- Characterized by distractibility, carelessness, difficulty following instructions, and a tendency to forget essential materials.
Automatic vs. Controlled Processes
- Automatic Processes: Routine actions performed without conscious thought, relying on pre-set rules or algorithms.
- Controlled Processes: Intentional cognitive activities requiring conscious awareness and effort.
Change Blindness
- A phenomenon where individuals fail to notice significant changes occurring in their visual field, highlighting limitations in attentional focus.
