Summary
Cognitive models of brain function benefit from capacity theories of selective attention. Understanding how limited processing capacity affects neural activity aids in predicting brain behavior.
Area of Science:
- Cognitive Neuroscience
- Neuroimaging
Background:
- Cortical function understanding requires predictive cognitive models.
- Capacity theories of selective attention offer a framework for interpreting neural activity.
Purpose of the Study:
- To apply capacity theory to the study of cortical function.
- To address recent issues in applying capacity theory to neural behavior.
Main Methods:
- Interpreting population-specific cortical activity.
- Utilizing capacity theories of selective attention.
- Formulating testable hypotheses based on process-specific load manipulations.
Main Results:
- Model founded on limited processing capacity.
- Different processes may draw on different capacities.
- Predicted patterns of activation covariation depend on shared processing capacity.
Conclusions:
- Capacity theory provides a valuable lens for understanding cortical function.
- Further research is needed to refine the application of capacity theory to neural behavior.

17.1K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.
