Behaviorism stresses the importance of having a particular form of behavior reinforced by someone, other than the student, to shape or control what is learned. In aviation training, the instructor provides the reinforcement. Frequent, positive reinforcement and rewards accelerate learning. This theory provides the instructor with ways to manipulate students with stimuli, induce the desired behavior or response, and reinforce the behavior with appropriate rewards. In general, the behaviorist theory emphasizes positive reinforcement rather than no reinforcement or punishment. Other features of behaviorism are considerably more complex than this simple explanation. Instructors who need more details should refer to psychology texts for a better understanding of behaviorism. As an instructor, it is important to keep in mind that behaviorism is still widely used today, because controlling learning experiences helps direct students toward specific learning outcomes.

Cognative Theory

Much of the recent psychological thinking and experimentation in education includes some facets of the cognitive theory. This is true in basic as well as more advanced training programs. Unlike behaviorism, the cognitive theory focuses on what is going on inside the student's mind. Learning is not just a change in behavior; it is a change in the way a student thinks, understands, or feels.
There are several branches of cognitive theory. Two of the major theories may broadly be classified as the information processing model and the social interaction model. The first says that the student's brain has internal structures which select and process incoming material, store and retrieve it, use it to produce behavior, and receive and process feedback on the results.
This involves a number of cognitive processes, including executive functions of recognizing expectancies, planning and monitoring performance, encoding and chunking information, and producing internal and external responses.
The social interaction theories gained prominence in the 1980s. They stress that learning and subsequent changes in behavior take place as a result of interaction between the student and the environment. Behavior is modeled either by people or symbolically. Cultural influences, peer pressure, group dynamics, and film and television are some of the significant factors. Thus, the social environment to which the student is exposed demonstrates or models behaviors, and the student cognitively processes the observed behaviors and consequences. The cognitive processes include attention, retention, motor responses, and motivation. Techniques for learning include direct modeling and verbal instruction. Behavior, personal factors, and environmental events all work together to produce learning.
Both models of the cognitive theory have common principles. For example, they both acknowledge the importance of reinforcing behavior and measuring changes. Positive reinforcement is important, particularly with cognitive concepts such as knowledge and understanding. The need to evaluate and measure behavior remains because it is the only way to get a clue about what the student understands. Evaluation is often limited to the kinds of knowledge or behavior that can be measured by a paper-and-pencil exam or a performance test. Although psychologists agree that there often are errors in evaluation, some means of measuring student knowledge, performance, and behavior is necessary.
