Humanistic perspective

• Often described as the “third force” in psychology, this outlook emphasizes the positive potential of human beings. It focuses on personal growth rather than the pessimism associated with the psychoanalytic model or the strict environmental determinism associated with behaviorism. Supporters argue that other perspectives can miss the richness of human experience and our capacity for self-directed change.
• In the hierarchy of needs model, basic physical and psychological needs must be met in sequence, culminating in self-actualization (the realization of one’s full potential). When needs aren’t met, emotional or behavioral problems may result. Another key idea is self-concept, which includes your thoughts and feelings about who you are (the real self) and who you would like to be (the ideal self).
• Congruence occurs when the real self and ideal self closely match, supporting healthy self-worth. Incongruence occurs when they don’t align, which can contribute to anxiety and maladjustment. Providing children with unconditional positive regard can help them develop closer alignment between the real self and ideal self.

Trait perspective

• In this framework, traits are consistent patterns of behavior that help define personality. Early theorists proposed very large lists of traits, and later work tried to narrow these down.
• Common categories include cardinal traits (dominant influences in a person’s life), central traits (core characteristics such as kindness or loyalty), and secondary traits (less consistent preferences that may depend on the situation).
• Another approach groups traits into a smaller set of basic dimensions. People are then scored along a continuum for each dimension, rather than labeling a trait as simply present or absent.

Biological perspective

• This approach argues that inherited predispositions and physiological processes help explain differences in personality. Evolutionary psychology examines universal personality features that may have offered survival advantages, along with individual variation. Behavioral genetics research (for example, studies of twins raised apart) often finds strong similarities in personality even in different environments, suggesting that some traits have a genetic component. Heritability refers to the proportion of variation in a trait within a population that can be attributed to genetic differences. Even so, traits typically don’t come from a single gene; they reflect the combined influence of many genes along with epigenetic factors.

Behaviorist perspective

• This perspective pushes back against biological determinism, arguing that personality is largely shaped by reinforcements and consequences in the environment. People learn stable behavior patterns because actions followed by positive outcomes tend to be repeated, while actions followed by negative outcomes tend to be avoided. Unlike the psychoanalytic view that early childhood largely fixes personality, the behaviorist view holds that behavior can keep changing across the lifespan.

Social cognitive perspective

• Combining learning principles with cognitive processes, this perspective highlights reciprocal determinism, observational learning, and self-efficacy as key influences on personality.
• Reciprocal determinism means that cognitive processes, behavior, and the environment influence one another in both directions. Self-efficacy - your belief in your ability to succeed - affects how you approach challenges and how persistently you pursue goals.

Situational approach to explaining behavior

• Findings that people don’t always behave consistently across contexts contributed to the person-situation debate (also called the trait vs. state controversy).
• Traits are stable, long-term characteristics that tend to show up across many settings. States are short-term patterns of behavior that are strongly shaped by the immediate situation. One position in the debate is that traits can help predict behavior, but situational factors may be just as important - or more important - in specific moments.
• A classic demonstration of self-regulation (also called will power, or the ability to delay gratification) comes from studies in which children could take one marshmallow immediately or wait to receive two rewards. Early self-regulation was linked to later academic and social outcomes, although later follow-up work suggests these results can depend on other factors (such as cognitive ability and family environment). This supports the idea that context matters when explaining behavior.
