tähelepanus

Tähelepanus, also known as attention, is a cognitive process that involves focusing on a particular stimulus or task while ignoring others. It is a fundamental aspect of human consciousness and plays a crucial role in learning, problem-solving, and decision-making. Attention can be divided into two main types: selective attention and divided attention. Selective attention involves focusing on a single stimulus or task, while divided attention requires attending to multiple stimuli or tasks simultaneously.

Attention is regulated by various factors, including internal states such as motivation, emotions, and cognitive load, as well as external factors such as the environment and task demands. The brain's attention network, which includes structures like the prefrontal cortex, parietal cortex, and basal ganglia, plays a key role in regulating attention. Dysfunction in this network can lead to attention-related disorders, such as attention deficit hyperactivity disorder (ADHD) and attention deficit disorder (ADD).

Attention can be measured using various methods, including behavioral tasks, neuroimaging techniques, and subjective reports. These methods have provided valuable insights into the neural mechanisms underlying attention and have helped to develop interventions for attention-related disorders. Overall, attention is a complex and multifaceted process that is essential for human cognition and behavior.
