Theories of Personality

This article reviews some of the major theories about personality, as well as its characteristics, predictions, and treatment. The key to designing a successful research project is to consider the needs and time constraints of your participants, as well as the limitations of the omnibus personality inventory. We will then examine the most commonly used methods of personality measurement, and provide a clear description of the characteristics of the traits most relevant to the study’s objectives. Here are some tips to help you choose the best one:

Theories of personality

There are a variety of theories of personality. These theories are based on the various factors that make people unique, such as their personalities. A classic example is the psychological theory by Carl Jung, which categorizes people into four basic types based on their primary psychological function. The thinking type is driven by a set of reasons, while the feeling type is guided by feelings, and the intuition type is influenced by undefinable internal stimuli.

Several other theories of personality have also been proposed, including Eysenck’s. His theory takes into account nature and nurture, arguing that personality is a combination of biological predispositions and environmental triggers. Eysenck’s theory links well with the diathesis-stress model of behavior, which argues that our behavior is a combination of environmental influences and biological predispositions. However, Cattell’s theory differs from Eysenck’s.


Among the many factors affecting a person’s behavior are their genetics, environment, and upbringing. Many of these factors are highly variable, however, so a person’s unique personality will probably differ from another’s. In addition, the physical traits of the individual, such as the sex, weight, and beauty of the individual, can have a significant impact on their personality. So, it is important to consider the cultural context in which an individual has a tendency to exhibit certain characteristics.

The five-factor model of personality includes two models. The first one assumes that each person possesses a set of core personality traits, called Big Five. The second model assumes that each person has a unique combination of these traits. The Big Five are: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to new experiences. These models assume high levels of inter-individual differences.


The study of smartphones can help scientists predict three major aspects of the Big Five personality dimensions. Specifically, smartphone usage can predict levels of agreeableness and emotional stability. The study is just one of many using smartphones to predict personality. Read on to learn more. Here are some of the most common ways to predict your personality traits. Weigh your options before making a decision. Don’t be afraid to experiment with new technology. It’s a great way to get a general sense of your own personality.

Social projection studies vary in their accuracy. Although they are highly effective for predicting behavior, they do not always give the most accurate predictions. For example, the majority of people based their personality traits on their own gender. Other personality traits that are often predicted by Facebook likes include religion (81%) and political party membership (85%). IQ was also predicted by liking curly fries. Those results are promising, but there are many more variables that need to be accounted for.


There are many factors that affect treatment for personality disorders. Patients with personality disorders tend to require longer sessions, more expensive treatment, higher attrition rates, and poorer treatment outcomes. However, the treatments for these patients are largely derived from the treatment for other emotional disorders rather than those specifically designed for personality disorder. In other words, it is not helpful to give an aspirin to a patient with personality disorder because it only addresses one symptom but not the core issue.

Until recently, many practitioners regarded personality disorder as incurable. They were often difficult to engage with, attended therapy intermittently, and engaged in self-destructive and violent behaviors. Some patients showed no improvement and enraged therapists. Others believed therapy only exacerbated the problem. But with the advances in our understanding of personality disorders, we are seeing more effective treatment options available to our patients. In today’s society, more people are seeking therapy to address their challenges.
