Study Notes

Kahneman's Central Capacity Theory (1973)

Proposed a resource model of attention, viewing attention as a limited pool of resources. These resources are allocated across different tasks.
Explains divided attention (performing multiple tasks simultaneously) and performance decline as task demands exceed available resources.

Key Components

Central Processor (Capacity): A single, flexible pool of resources shared across all tasks. These resources are finite.
Arousal Level: Influences the total attention resources available. Higher arousal (excitement, urgency) increases capacity to a point; excessive arousal (stress) reduces efficiency.
Enduring Dispositions: Automatic, involuntary factors capturing attention (e.g., a loud sound).
Momentary Intentions: Voluntary, goal-directed factors allocating attention based on current priorities (e.g., studying).
Allocation Policy: Determines how resources are divided between tasks, depending on task demands, priority, and automatic vs. controlled processes (automatic processes require fewer resources).
Evaluation of Demands: The brain constantly assesses if available resources can meet ongoing task demands. If demands are high, performance declines (errors, slower responses).

Key Concepts of Divided Attention

Multiple Tasks and Filtering: Tasks compete for attention. Low-demand tasks can often be done simultaneously. High-demand tasks together decrease performance.
Shift from Bottleneck to Resources: From a bottleneck model (strict sequential processing), Kahneman's theory proposes that attention resources are divided among multiple tasks. Success in multitasking depends on resource demands in total.

Strengths of the Model

Flexibility: Explains simultaneous task performance better than earlier models which just focused on sequential processing.
Task Priority: Explains prioritizing tasks in situations where resource availability is insufficient.
Dynamic Resource Allocation: Acknowledges that attention varies based on arousal and task difficulty.

Problems/Limitations

Independent Measure of Resources: Quantifying attention resources is challenging.
Task-Specific Models: Some tasks (e.g., visual vs. auditory) might involve distinct resource pools.
Oversimplification: The model doesn't fully account for specialized cognitive processing systems.

Applications

Multitasking: The model explains why multitasking often reduces performance, such as driving and texting.
Workload Management: Important in domains like aviation to design less demanding workflows/interfaces.
Cognitive Load: Fundamental to understanding how cognitive load impacts instructional design and learning, emphasizing minimizing unnecessary task demands.
