Study Notes
Different Types of Attention
- Attention refers to the allocation of neural processing resources and can be divided into different types based on functional policies.
- Attention can be divided into two categories based on the pathways of neural processing: bottom-up and top-down.
- Bottom-up attention is the spontaneous and involuntary allocation of attention to salient physical features of environmental stimuli that activate sensory parts of the brain.
- In bottom-up attention, stimulus processing starts from bottom neural regions and results are sent to the neural regions at the top brain areas.
- Bottom-up attention is also known as "stimulus-driven" or "exogenous attention" and is more sensitive to certain physical features such as red color, flashing light, and roughness.
- Some computational models have been proposed to explain the characteristics of bottom-up attention.
- The dynamic of the bottom-up attention system is fast and is activated at the initial moments of receiving sensory inputs.
- The sensitivity of the bottom-up attention system can be affected by repetitive presentation of stimuli, drowsiness, and other factors.
- The influence of top-down processors has been shown during the early stages of bottom-up attention processing.
- The bottom-up attention system does not use memory content, but the sensitivities of the system can change based on culture, society, and environment.
- People usually extract the statistics of their environment, and when they enter a new environment that does not match their prior statistics, it can trigger learning procedures to reinstate new statistics.
- Retrieving the prior statistics and stabilizing the new ones require memory access, which is when bottom-up attention interacts with specific kinds of memory.
