Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.6K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Criticisms of the Evolutionary Perspective

375
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

The Behavioral Perspective on Personality01:19

The Behavioral Perspective on Personality

821
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

Social Cognitive Perspective on Personality

1.0K
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Changes in Skin Color: Clinical Perspectives

3.5K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Carl Rogers' Humanistic Perspective on Personality01:23

Carl Rogers' Humanistic Perspective on Personality

2.0K
Carl Rogers, a key figure in humanistic psychology, believed that individuals possess an innate potential for growth and fulfillment. According to his model of personality, three significant components define an individual: the organism, the self, and conditions of worth.
The organism refers to an individual's inherent blueprint, which Rogers saw as innately positive and directed toward helping others, unlike Freud's view of the id as driven by base impulses. The self is a person's...
