Indicate your subject in the "School Subject" box, so those with expertise in the area will respond to the question.

Please proofread your question before posting it. Your frequent typos make you question hard to understand. I'm not quite sure what you are asking.

Try looking up each of these terms on Google paired with the term "history" and possibly the year intervals as your key words.

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

To help you better understand the major concepts or events in the history periods you mentioned, let's break it down by each period:

1930-1950:
1. Freudian Psychoanalytic Theory: One major concept in this time period is Sigmund Freud's psychoanalytic theory, which emphasized the role of unconscious processes and early childhood experiences in shaping personality.
2. Humanistic Theory: Another significant concept is the emergence of humanistic psychology, which focused on the study of human potential, self-actualization, and personal growth.
3. Cognitive Theories: The cognitive revolution during this time introduced new ways of studying the mind and behavior, emphasizing mental processes such as perception, memory, and problem-solving.
4. Learning Theories: Behaviorism, influenced by theorists like B.F. Skinner, was a dominant force during this period, emphasizing the importance of observable behavior and reinforcement in learning.
5. Cognitive/Cognitive Learning: This concept refers to the combination of cognitive processes and learning theory, leading to the development of cognitive-behavioral approaches that integrated cognitive and behavioral principles.

1950-1970:
1. Three-Factor Model: In this period, Eysenck proposed a personality model with three basic dimensions: extraversion-introversion, neuroticism-emotional stability, and psychoticism versus self-control.
2. Measuring Validity: There was an increased focus on assessing the validity of psychological tests and measurement tools during this time, improving the accuracy and reliability of psychological assessments.
3. Trait-based vs. Situation-based Approaches: The debate between trait-based and situation-based approaches to understanding personality became more pronounced during this period, with researchers exploring the influence of both stable personality traits and situational factors on behavior.

1970-Present:
1. Personality Traits Definition: During this period, there was a continued development of comprehensive trait theories and an ongoing effort to define and measure personality traits more precisely.
2. Observational Learning Development: In the field of learning and social cognition, observational learning (also known as social learning or modeling) became further developed. Researchers examined the effects of observing and imitating others' behaviors on learning and behavior change.
3. (Additional Concepts): Beyond the scope of your inquiry, other important concepts in this period include the emergence of positive psychology, the study of emotions, advancements in neuroscience and genetics, and the integration of different theoretical perspectives in personality psychology.

I hope this breakdown helps you better understand the major concepts and events in the specified history periods. Remember, it's always a good idea to consult your course materials, textbooks, or reputable online sources for more information and to ensure accuracy in your academic work.
