In the context of psychology, a chamber often refers to a controlled environment used for experiments or observations. These chambers are designed to study behavior under regulated conditions and are common in behavioral and cognitive psychology.

General Description

Psychological chambers are specifically designed spaces that allow researchers to control and manipulate environmental variables to observe their effects on test subjects, usually animals like rats or pigeons. The most famous example is the Skinner Box, named after B.F. Skinner, a pioneer in the study of behaviorism. This chamber is used to study operant conditioning by controlling rewards and punishments.

Chambers can vary in complexity from simple enclosures that isolate the subject from external stimuli to highly sophisticated environments that can simulate a wide range of conditions. They are instrumental in experiments involving learning, memory, and psychological conditioning.

Application Areas

  • Behavioral Psychology: Chambers are used to conduct experiments on conditioning, learning processes, and decision-making behaviors.
  • Cognitive Psychology: Used to study how sensory inputs are processed and how this processing leads to specific behavioral outputs.
  • Developmental Psychology: Sometimes used to observe how different environmental factors affect developmental stages in children under controlled conditions.

Treatment and Risks

In therapeutic or clinical settings, the concept of a psychological chamber isn't typically used for treatment but remains a valuable tool for empirical research that can inform therapeutic practices. For example, understanding the mechanisms of learning and conditioning in a Skinner Box can help in developing behavioral modification therapies.

However, ethical considerations are paramount when using chambers for psychological experiments, especially regarding the welfare of animal subjects. There is a constant need to balance scientific inquiry with humane treatment principles.

Similar Terms

  • Isolation Chamber: Used to study effects of sensory deprivation on the human psyche.



In psychology, a chamber is a controlled environment designed for conducting experiments that investigate behavioral and cognitive functions. These chambers are crucial for isolating variables and precisely measuring the effects of environmental changes on psychological responses.
