Evolutionary, Behavior Psychology of Human

Human evolutionary psychology is the study of the processes of human development. The changes that have occurred during the life time of the man is studied based on two perspective 1) phylogenetic and 2) ontogenetic.

Phylogenetic Study: It involves the evolutionary history of various species during the humanization process.

Octogenetic Study: It studies the formation and development of adult behavior.

The adaptability of man is a cultural phenomenon because it is the product of learning. Human evolutionary psychology is a continuous, flexible and global human development where the psychological changes occur throughout the life. A human is born with limited behavior but has the power of adaptability and learning and because of which one differentiates every individual from other.

Several trends have contributed their findings to evolutionary human psychology, psychoanalysis and Piaget’s genetic psychology, socio-cultural model of Vygotsky, learning theories, the model of information processing in recent times and also the ecological model the ethological. Series of tasks involved in human development, characteristic of different stages. These tasks are largely imposed by society and culture, socialization processes, and integrate the individual.

Object of study of developmental psychology:

The main objectives are to describe the behavior of individuals, and how they evolve, to identify the causes and processes leading to these changes from one stage to another. Other authors relate these changes with life stage, circumstances and environment, and experiences of each individual.

The stage theory of Piaget:

Piaget proposed the study of human knowledge in an evolutionary and diachronic, of genetic epistemology, trying to explain the evolution of human knowledge, both as individual species. Studies the evolution of childhood intelligence and it proposes three stages: the sensorimotor period, the concrete operational and formal operations. Where newborn reflexes are related to sensory-motor intelligence. Specific operations are with the emergence of language and scientific thinking to formal operations.

However, there are intermediate stages linked to qualitative changes. The structure and mechanisms of change are rooted in biology: adaptation and self-regulation or balance. Adaptive exchange between the organism and the environment is similar to that between subject and object of knowledge, a psychological level. The mind seeks balance and the individual's actions arise when the imbalance appears, looking back on.

Assimilation and accommodation allow the subject to incorporate new objects to their cognitive structure and accommodation transforms its previous structure adapting to new knowledge.

Patterns of knowledge are changing continuously depending on the circumstances and roles to play. Applying these to the new object of knowledge given by the process of assimilation and accommodation. Human intelligence is the result of exchanges between the subject and the environment. However, heredity is important in development because there are factors of a structural nature associated with the formation and maturation of the nervous system.
