Learning is defined as a “process of change that occurs as a result of an individual’s experience” (Mazure, 2006). Researchers assume that the process of learning follows certain general principles, which were developed, into the general process learning theories. These include operant conditioning and classical conditioning which has been put forward by leading psychologists like Pavlov, B.F.Skinner and Thorndike. However, in learning, operant and classical conditoning are opposed by biological constraints that state that there are limitations to the theories. Some of these biological constraints on learning will be discussed below.
Learning through operant conditioning allows a conditioned behaviour to increase or decrease in the presence of reinforcement or punishment. However, this process can be affected by instinctive behaviours that would disrupt the conditioned behaviour. According to a study conducted by Breland and Breland (1961) they tried to condition a raccoon to pick up coins and drop them into a container. The raccoon however spent time rubbing the coins together and rubbing the coin on the inside of the container before finally dropping it in and receiving its food reinforcement. Even after conditioning, the raccoon’s need to rub the coins together became worse as he spent more and more time just rubbing the coins. This is known as instinctive drift where the raccoon’s instinctive behaviours limited its ability to perform the conditioned response. Therefore the raccoon failed to learn due to its innate tendencies that acted as a biological constraint and operant conditioning failed in teaching the raccoon through reinforcement.
In the same study by Breland and Breland (1961) a pig was conditioned to pick up wo...

But studies by Domjan and Galef (1983) on the constraints of learning suggest that there is no basis as such on which general process learning theories are unsustainable. According to them this is because the study of both operant and classical conditioning now include many of the phenomena that was initially not incorporated into the theories. Domjan and Galef (1983) state that although biological constraints have not prevailed as such, many of the investigations into constraint theory have drawn key empirical findings to the understanding of the general process learning theories.
Therefore, according to the above a general process learning theory is sustainable even in the presence of biological constraints as behaviour can be reinforced and manipulated in most cases to acquire a desired behaviour.

Learning Theory Essay

- Learning is defined as a, "relatively permanent change in an organism's behavior due to experience" (Myers, 2010). The purpose of this paper is to present a critical analysis of the different theoretical approaches and explanations for learning through an examination of the theories of behaviorism, social learning and cognitive. I will investigate the principles and postulates of each theory, their strengths and their weaknesses. It is my belief that because each theory is best applicable to varying types of learning, it is best that a combination of each is used to provide the most complete learning experience....   [tags: behaviorism, social learning, cognitive learning]

The Constraints on Adolescent Learning Essay

- Personalities, social skills and intellectual development are only some of the key factors that effect how pupils learn and achieve differently to one another. Every child responds individually to their specific needs and environment, and the extent of that achievement can be often be linked with external factors as pupils are naturally influenced by a variety of different constraints. These factors that are not concrete and will change and alter throughout an adolescent’s development, as Piaget (Piaget 1970) believed the mind changes and works in different ways at different stages so do the conditions that enhance and limit progress....   [tags: Education Teaching]

Two sides on the same coin: Relationship between constraints and creativity

- Two sides on the same coin: Relationship between constraints and creativity Constraints can influence on creativity both negatively and positively. Constraints generally undermine creativity by inhibiting uniqueness and intrinsic motivation to a large extent. In a sense, the best way to improve and develop creativity is to identify and eliminate all constraints. Yet this is not always the case in most of creativity works. That is to say, constraints also have a positive impact on creativity under certain circumstances....   [tags: relationship constrains and creativity]

Essay on Internal and External Constraints on Free Will

- Internal and External Constraints on Free Will The concept of free will in and of itself is a complex issue with many factors weighing heavily upon it. To say that one is absolutely free in making decisions is shortsighted and naive. For example, environmental, social, biological, and even evolutionary factors greatly effect the way in which we go about choosing a viable option. To be able to make a completely free decision, one would have to live in a vacuum devoid of all external influences. However, one would still have to consider the internal constraints acting upon our will to choose....   [tags: Papers]
