PSYCH 645 Assignment 5 Personality Development

Personality Development

The development of personality is a broadly debated conceptualization. Various speculations address what factors influence the development of personality characteristics. The Five Factor Model talks about personality as far as traits that remain relatively stable over the lifespan. The biological model zeros in much on hereditary influences, while different models center around the impact of environmental factors. The following will address hereditary, environmental, and cultural influences on personality, as well as adaptations of therapies for the biological model, the Five-Factor trait hypothesis, and the temperament model of personality.

The Quality Climate Interaction and Influence on Personality Researchers have concentrated on behavioral hereditary qualities in the course of particular breeding of animals. Ethical considerations forestall studying individuals in this manner, yet the investigation of animals can give insight into the typical behavior of individual animals that have explicit hereditary parts. 

According to Cervone and Pervin (2013), unique types of canines can be presented to similar environmental upgrades to determine contrasts in reactions based on hereditary contrasts. These examinations can assist with determining predetermined biological factors that influence various results in the existence of genetically contrasting individuals.

Research’s Clark and Watson distinguished three factors, According to Cervone and Pervin (2013), three sorts of nature versus sustain factors are clear. To start with, parenting styles may have a significantly unique impact depending upon the reaction level of the kid. Second, parenting styles may vary depending upon the responsivity of the youngster. Finally, individuals with various hereditary parts may gravitate toward or create a climate that is suitable for their hereditary inclination. So, biological and environmental factors have a significant influence on personality, however, it is hard to determine how much each component contributes.

Culture as a Factor in the Development of Personality

Culture has a significant impact on the formation of personality characteristics. Components like language, financial status, and interpersonal interactions can contribute significantly to an individual’s development of personality. One limitation of the Five-Factor Model is that a few characteristics don’t translate well between certain languages and cultures. 

This idea presents the inquiry: do all cultures display certain personality traits? Cultural contrasts significantly impact personality in several ways. Western culture emphasizes individual achievements, while Eastern cultures emphasize family gatherings and local areas (Berk, 2014). This can cause contrasts in how individuals view themselves as well as other people. 

According to Kitayama (2011), individuals from various cultures attribute behavior to various factors. Eastern cultures consider social circumstances while assessing the reactions of others, while individuals from Western cultures make decisions based on personal characteristics. Fundamentally, culture exists in all conditions.

Twin Examinations and Inheritability of Personality

The argument of nature versus support has existed for quite a long time. According to Cervone and Pervin (2013), twin examinations give proof that personality traits are largely inherited. Twin examinations are typically led by examining the development of monozygotic (identical) or dizygotic (fraternal) twins in the same climate. Occasionally, conditions exist where twins are raised in vastly various backgrounds. Regardless of the distinctions in parenting styles and living circumstances, studies have shown that twin maintains relatively similar personality characteristics (Cervone and Pervin, 2013). Adoption studies, concentrate on that examine the personality characteristics of an adopted kid concerning their adoptive family’s home versus traits of the biological family, and also indicate similarities that help the idea of inheritability of personality traits.

Stability of Temperament Characteristics Over the long haul That Adds to Adult Personality. An individual’s temperament is defined by how they experience feelings and answer them. Proof proposes that attitude largely remains reliable over the lifespan (Cervone and Pervin, 2013). Science determines an individual’s temperament in infancy however is later impacted by cultural and environmental influences.

Jerome Kagan recognized two distinct temperamental styles of kids through direct observation in the laboratory setting and parental reports of their youngsters’ reactions to improvements (Cervone and Pervin, 2013). From his research, Kagan was able to foster inhibited and uninhibited behavioral profiles. Youngsters that displayed characteristics of the inhibited pattern typically answered negatively to adverse situations. 

When stood up to a renewed individual or situation, inhibited kids were emotionally reactive and would in general withdraw, seeking support from the parent or familiar individual. Uninhibited youngsters were bound to be more than happy and responsive in the same situations. Kagan also finished longitudinal examinations on many of his subjects and noted textures between temperament in early adolescence and reactions all through later youth. Although these characteristics showed consistency as the age of the kids advanced, there was also proof to help that a portion of these characteristics may change over the long haul depending on environmental factors (Cervone and Pervin, 2013). Kagan also addressed the job of youngster-rearing practices.

He determined that highly reactive youngsters had the potential to turn out to be less reactive depending upon external encouragement from the mother. Although Kagan surrendered that change is conceivable, he continued to stand by the idea that hereditary inclination was challenging to defeat totally (Cervone and Pervin, 2013). According to Lombard-Vance (2011), temperament stabilizes over the long haul through the lifespan with age and various stages of development.

Adaptation of Personality Models for Variation in Personal, Societal, and Cultural Factors. The biological model bases variations of personality on science. This model emphasizes the impact of brain science on personality rather than environmental factors. The five-factor model takes a comprehensive perspective on personality (Cervone and Pervin, 2013). Individual distinguished traits combine to frame an overall image of one’s personality. The temperament model defines three distinct temperaments that an individual can have. These are defined as easy, slow to warm up, and troublesome (Cervone and Pervin, 2013).

Although each of these speculations gives portrayals of personality types and their development, none of these hypotheses completely explains the origin and advancement of individual personality all alone. Each approach adds to the field, yet more than one strategy is expected to examine an individual’s personality carefully. PSYCH 645 Assignment 5 Personality Development


Personality can be defined and analyzed in many ways. Clinicians have estimated the development of personality for a really long time. Although many of these hypotheses give insight into personality development, none has fostered a far-reaching model that completely explains each aspect of the nature of personality development. What defines an individual’s impression of reality and their considerations, feelings, and reactions are determined by many factors. Analysts will continue to endeavor to foster the ultimate personality hypothesis, yet none have had the option to squeeze all aspects of the human experience into one neatly arranged approach. The uniqueness of the human experience forestalls such complete analysis. Regardless of how far-reaching a hypothesis becomes, not all individuals will fit the form. Such is the nature of human individuality.
