Biological Foundations (graded) |
An ongoing debate continues on the influence of nature and nurture on human behavior. If you had to argue that either genetics (nature) or environment (nurture) has the greater impact on human development, which would you pick and why?

Learning (graded) |
After you have read about the theories of learning, reflect on how you learned as a child. What methods did your parents use to teach you how to act? Was it through classical conditioning? What about operant conditioning and social learning theory? Which theory had the biggest impact? Why? Give an example and state how it has impacted the person you are today.

We all seem to want a good memory (What are my coworkers names? Where did I leave my computer? What day was I supposed to submit that proposal to my boss?). These might be typical memory issues.

Motivation and Emotion (graded)
From your reading, you have seen that there are several theories of motivation. You may also sense that some of the theories may not specifically apply to you. Given that introduction, which theory of motivation is the best fit for describing your behavior?
Theories of Personality (graded)
Theories of personality are based on observations of how humans develop behavior patterns. Psychological testing assumes there are certain fixed aspects of human personality and those aspects can be identified through standardized measurements. As part of your application for a position, you may be administered one of these tests to determine if you are a good fit for the company. The Big Five personality trait assessment is in your Webliography. Take this assessment and comment on (1) its accuracy for you and (2) which of those traits may change over time.

Physical, Cognitive and Social Development (graded)
Human development is a process in which there are various cognitive, physical, social, and emotional milestones from conception to death, all of which require mastery.

Please provide an explanation to support your answer.
Sexuality and Gender (graded)
Understanding sexuality varies from culture to culture, yet there are basic biological, cognitive, and emotional components in sexuality and sexual development.
