Humanistic theories
Humanistic psychology emphasizes that people have free will and that this plays an active role in determining how they behave. Accordingly, humanistic psychology focuses on subjective experiences of persons as opposed to forced, definitive factors that determine behavior. Abraham Maslow and Carl Rogers were proponents of this view, which is based on the "phenomenal field" theory of Combs and Snygg (1949).[42] |Rogers and Maslow were among a group of psychologists that worked together for a decade to produce the Journal of Humanistic Psychology. This journal was primarily focused on viewing individuals as a whole, rather than focusing solely on separate traits and processes within the individual.Robert W. White wrote the book The Abnormal Personality that became a standard text on abnormal psychology. He also investigated the human need to strive for positive goals like competence and influence, to counterbalance the emphasis of Freud on the pathological elements of personality development.[43]
Maslow spent much of his time studying what he called "self-actualizing persons", those who are "fulfilling themselves and doing the best they are capable of doing". Maslow believes all who are interested in growth move towards self-actualizing (growth, happiness, satisfaction) views. Many of these people demonstrate a trend in dimensions of their personalities. Characteristics of self-actualizers according to Maslow include the four key dimensions:[44]
- Awareness - maintaining constant enjoyment and awe of life. These individuals often experienced a "peak experience". He defined a peak experience as an "intensification of any experience to the degree there is a loss or transcendence of self". A peak experience is one in which an individual perceives an expansion of his or herself, and detects a unity and meaningfulness in life. Intense concentration on an activity one is involved in, such as running a marathon, may invoke a peak experience.
- Reality and problem centered - having a tendency to be concerned with "problems" in surroundings.
- Acceptance/Spontaneity - accepting surroundings and what cannot be changed.
- Unhostile sense of humor/democratic - do not take kindly to joking about others, which can be viewed as offensive. They have friends of all backgrounds and religions and hold very close friendships.
Biopsychological theories
Biology plays a very important role in the development of personality. The study of the biological level in personality psychology focuses primarily on identifying the role of genetic determinants and how they mold individual personalities.[45] Some of the earliest thinking about possible biological bases of personality grew out of the case of Phineas Gage. In an 1848 accident, a large iron rod was driven through Gage's head, and his personality apparently changed as a result, although descriptions[46] of these psychological changes are usually exaggerated.[47][48]Genetic bases of personality
Ever since the Human Genome Project allowed for a much more in depth understanidng of genetics, there has been an ongoing controversy involving heritability, personality traits, and environmental vs. genetic influence on personality. The human genome is known to play a role in the development of personality.Previously, genetic personality studies focused on specific genes correlating to specific personality traits. Today's view of the gene-personality relationship focuses primarily on the activation and expression of genes related to personality. Genes provide numerous options for varying cells to be expressed, however, the environment determines which of these are activated. Many studies have noted this relationship in varying ways in which our bodies can develop, but the interaction between genes and the shaping of our minds and personality is also relevant to this biological relationship.[50]
DNA-environment interactions are important in the development of personality because this relationship determines what part of the DNA code is actually made into proteins that will become part of an individual. It has been noted that while different choices are made available by the genome, in the end, the environment is the ultimate determinant of what becomes activated. Small changes in DNA in individuals are what lead to the uniqueness of every person as well as differences in looks, abilities, brain functioning, and all the factors that culminate to develop a cohesive personality.[51]
Cattell and Eysenck have proposed that genetics have a strong influence on personality. A large part of the evidence collected linking genetics and the environment to personality have come from twin studies. This "twin method" compares levels of similarity in personality using genetically identical twins. One of the first of these twin studies measured 800 pairs of twins, studied numerous personality traits, and determined that identical twins are most similar in their general abilities. Personality similarities were found to be less related for self-concepts, goals, and interests.[52]
Twin studies have also been important in the creation of the five factor personality model : neuroticism, extraversion, openness, agreeableness and conscientiousness. Neuroticism and extraversion are the two most widely studied traits. A person that may fall into the extrovert category can display characteristics such as impulsiveness, sociability, and activeness. A person falling into the neuroticism catergory may be more likely to be moody, anxious, or irritable. Identical twins however, have higher correlations in personality traits than fraternal twins. One studied measuring genetic influence on twins in five different countries found that the correlations for identical twins were .50, while for fraternal they were about .20.[52] It is suggested that heredity and environment interact to determine one's personality.[53]
Evolutionary theory
Charles Darwin is the founder of the theory of the evolution of the species. The evolutionary approach to personality psychology is based on this theory.[54] This theory examines how individual personality differences are based on natural selection. Through natural selection organisms change over time through adaptation and selection. Traits are developed and certain genes come into expression based on an organism's environment and how these traits aid in an organism's survival and reproduction.The theory of evolution has wide ranging implications on personality psychology. Personality viewed through the lens of evolutionary psychology places a great deal of emphasis on specific traits that are most likely to aid in survival and reproduction, such as conscientiousness, sociability, emotional stability, and dominance.[55] The social aspects of personality can be seen through an evolutionary perspective. Specific character traits develop and are selected for because they play an important and complex role in the social hierarchy of organisms. Such characteristics of this social hierarchy include the sharing of important resources, family and mating interactions, and the harm or help organisms can bestow upon one another.[54]
Mate competition within humans is theorized to play a very important role in the development of personality through evolution. Characteristics that are typically selected for through evolution are usually related to fertility and sexuality, as these traits will help ensure the continuation of the species. Some examples of this are traits that females seek in males related to features that will be helpful in a partner such as dominance, powerful status, and access to resources.[54] Another such trait that can be explained by an evolutionary standpoint is sexual jealousy. Males are in competition to reproduce with the most fertile females and in order to prevent other weaker and less adept males from mating with their potential partners over time males evolved a predisposition to rage, aggression, and jealousy. It has also been speculated that violence and killing is much more common in young males because they need to eliminate their competition in order for successful mating and reproduction to occur. Consequently, the age in which killing occurs the most frequently in males is also the age in which mating is the highest.[56]
One of the reasons in which men pursue romantic relationships can be explained by evolutionary theory. Sexual and romantic relationships increase the likelihood that an individual will be able to pass on his genetic material so men are predisposed to pursuing many women. Women have a different set of priorities because once they are pregnant they cannot reproduce during this time period and when they are rearing children they need to use the time they have available to nurture and protect them. Studies have supported this idea and found that in the area of romantic relationships and sexual behavior men had felt much more regret looking back on the sexual experiences they did not have then did women.[57]
Personality tests
There are two major types of personality tests, projective and objective.Projective tests assume personality is primarily unconscious and assess individuals by how they respond to an ambiguous stimulus, such as an ink blot. Projective tests have been in use for about 60 years and continue to be used today. Examples of such tests include the Rorschach test and the Thematic Apperception Test.
The Rorschach Test involves showing an individual a series of note cards with ambiguous ink blots on them. The individual being tested is asked to provide interpretations of the blots on the cards by stating everything that the ink blot may resemble based on their personal interpretation. The therapist then analyzes their responses. Rules for scoring the test have been covered in manuals that cover a wide variety of characteristics such as content, originality of response, location of "perceived images" and several other factors. Using these specific scoring methods, the therapist will then attempt to relate test responses to attributes of the individual's personality and their unique characteristics.[58] The idea is that unconscious needs will come out in the person's response, e.g. an aggressive person may see images of destruction.
The Thematic Apperception Test (also known as the TAT) involves presenting individuals with vague pictures/scenes and asking them to tell a story based on what they see. Common examples of these "scenes" include images that may suggest family relationships or specific situations, such as a father and son or a man and a woman in a bedroom.[59] Responses are analyzed for common themes. Responses unique to an individual are theoretically meant to indicate underlying thoughts, processes, and potentially conflicts present within the individual. Responses are believed to be directly linked to unconscious motives. There is very little empirical evidence available to support these methods.[60]
Objective tests assume personality is consciously accessible and that it can be measured by self-report questionnaires. Research on psychological assessment has generally found objective tests to be more valid and reliable than projective tests. Critics have pointed to the Forer effect to suggest some of these appear to be more accurate and discriminating than they really are. Issues with these tests include false reporting because there is no way to tell if an individual is answering a question honestly or accurately.
Inner Experience
Psychology has traditionally defined personality through its behavioral patterns, and more recently with neuroscientific studies of the brain. In recent years, some psychologists have turned to the study of inner experiences for insight into personality as well as individuality. Inner experiences are the thoughts and feelings to an immediate phenomenon. Another term used to define inner experiences is qualia. Being able to understand inner experiences assists in understanding how humans behave, act, and respond. Defining personality using inner experiences has been expanding due to the fact that solely relying on behavioral principles to explain ones character may seem incomplete. Behavioral methods allow the subject to be observed by an observer, whereas with inner experiences the subject is its own observer.[61][62]Methods measuring inner experience
Descriptive experience sampling (DES), developed by psychologist Russel Hurlburt. This is an idiographic method that is used to help examine inner experiences. This method relies on an introspective technique that allows an individual's inner experiences and characteristics to be described and measured. A beep notifies the subject to record their experience at that exact moment and 24 hours later an interview is given based on all the experiences recorded. DES has been used in subjects that have been diagnosed with schizophrenia and depression. It has also been crucial to studying the inner experiences of those who have been diagnosed with common psychiatric diseases.[62][63][64]Articulated thoughts in stimulated situations (ATSS): ATSS is a paradigm which was created as an alternative to the TA (think aloud) method. This method assumes that people have continuous internal dialogues that can be naturally attended to. ATSS also assesses a person’s inner thoughts as they verbalize their cognitions. In this procedure, subjects listen to a scenario via a video or audio player and are asked to imagine that they are in that specific situation. Later, they are asked to articulate their thoughts as they occur in reaction to the playing scenario. This method is useful in studying emotional experience given that the scenarios used can influence specific emotions. Most importantly, the method has contributed to the study of personality. In a study conducted by Rayburn and Davison (2002), subjects’ thoughts and empathy toward anti-gay hate crimes were evaluated. The researchers found that participants showed more aggressive intentions towards the offender in scenarios which mimicked hate crimes.[62]
Experimental method: This method is an experimental paradigm used to study human experiences involved in the studies of sensation and perception, learning and memory, motivation, and biological psychology. The experimental psychologist usually deals with intact organisms although studies are often conducted with organisms modified by surgery, radiation, drug treatment, or long-standing deprivations of various kinds or with organisms that naturally present organic abnormalities or emotional disorders. Economists and psychologists have developed a variety of experimental methodologies to elicit and asses individual attitudes where each emotion differs for each individual. The results are then gathered and quantified to conclude if specific experiences have any common factors. This method is used to seek clarity of the experience and remove any biases to help understand the meaning behind the experience to see if it can be generalized.[61]
