To talk about changes in personality, we have to think about transforming traits or cognitive styles that comprise

Wondering about the possibility of changes in the personality is doing on the transformation of the traits or cognitive styles within it. Traits are theoretical structures that can not be observed directly and, we presume from the behavior of individuals. In personality psychology handled this concept to refer to both biological substrate or genotype, how its social manifestation or phenotype. A genotype level, the features are defined as a set of genetically determined characteristics that contribute significantly to a stable feature of behavior. From the phenotype level is considered to result from the interaction of genotype with all influences, educational, cultural and socioeconomic, received by an individual throughout his life.

Phenotype traits

The traits considered at the phenotype level, are more likely to change their genetic or biological substrate. Then it is easier to change social behavior genes. Among the genes and social behavior are several intermediate levels relating to the personality. The genetic structure becomes the basis on which the whole structure is built over our lives. Genes are the source of all behavior, and determine the structural characteristics, the anatomical part of our brain.


The brain is organized into neuronal pathways and neurotransmitters dependent enzymes. The functionality of nerve pathways other hand, leads to physiological systems that encourage information processing experience and emotions. Thus these systems allow us the possibility of learning, which in turn leads to the development of trends or rules of conduct in society, and as a result, the overall behavior. Eventually the environment may change the probability that they manifest.

Personality Disorders

The features that are at the phenotype level, one can modify the extent that changes occur in one or more of those mentioned levels. Therefore, the administration of agents can create stable alterations in some of them. However, personality changes may also result from structural changes in the brain but, we must remember that the genetic structure can only be changed through genetic engineering. Only in the event of a change in that level, one could speak of personality disorders at the genotype level.

Not all features, which would manifest along lifetime. Some that have been observed at early ages (children), they may go away in adulthood. There is however the possibility that other emerging during this period. Indeed, various environmental influences during childhood and adolescence, it may encourage different behavioral manifestations in people with similar genotype characteristics. personality in adults is more stable than in children or adolescents. In such consistency is relatively high, considering time not very long.

Although decreases significantly, if we compare the personality characteristics of childhood with adolescence, or it with adulthood. Phenotype traits are not modified by interventions only biological, environmental changes incidental, or evolutionary development. psychological intervention techniques , psychotherapy, aimed at establishing stable changes in the way they behave, the interpretation of the experiences or expression of ideas.

Psycho therapeutic techniques

Psycho therapeutic techniques are used, among other things, to teach people to be less shy, more assertive, optimistic, more flexible. Therefore, some of these interventions may also cause changes in personality at the phenotype level. Keep in mind that, not all individuals are equally likely to experience such changes. It would end, to illustrate the degree of consistency of some personality characteristics, we find, at the clinical level, in so-called personality disorders. Psychological and psychiatric interventions in these disorders are long and complicated, and not always get the desired success. Consistency in the way people react, feel and behave is one of the essential ideas in most of the definitions of personality. But, despite that, and the empirical evidence of a degree of stability in the conduct, traits can have many different causes modifications and in different degrees.


Still, Can one speak of personality transformation, by the fact itself, that change some aspects? The answer to this question depends on the importance that possess the traits to the individual’s functioning. Indeed we know that human individuality is complicated and is influenced by a large number of variables that make it difficult to conclude a change global, unless it involves a significant number of its components.
