Assignment: Reflection Journal

Overview

image of 10 skills

Since you started PSY101, Smarter Decisions through Psychology, you have had the opportunity to learn about fascinating topics, including the brain and nervous system, emotions, motivation, and stress management. As you learned the psychological concepts and principles covered in this course, you’ve gained insight into what influences decision making and how you can apply what you’ve learned to make better decisions in your own life and career. Through your study of psychology, you’ve also started honing two essential employability skills:

Problem solving to identify and frame problems, explore ideas, and create effective, ethical, and evidence-based solutions based on psychological concepts and principles.

Self and social awareness to monitor one’s own and others’ emotions, to discriminate among them, and to use the information to receive feedback, reflect, and guide one’s thinking.

Questions

In this journal, you will share your reflections on your time in PSY101 by answering the questions below. For each of the questions, write a paragraph-length response (5-7 sentences).

1. As a result of this class, how will you immediately apply your problem solving skill at home or work?

2. As a result of this class, how have you grown in terms of your own self & social awareness skill?

3. Of all of the Strayer videos, which one was most relevant for you? Why?

Explain how creative decision-making can improve our ability to make better decisions, considering the numerous obstacles to do so.

/in /by
  • Decision-Making
  • Based on our content this week, discuss the importance of rationale decision-making in an organization, using necessary citations. Include how bounded reality, cognitive biases, and conjunction fallacy might affect decision-making.
  • Attribution Theory
    • Explain attribution theory using necessary citations. Include a discussion about the effects of consistency, consensus, distinctiveness, and fundamental attribution error. Consider inclusion about the effects of perception, primacy and recency effects, selective perceptions, contrast effect, stereotyping to further support your discussion.
  • Personal Experience: Inaccurate Judgement
    • Based on our content this week, consider your own experiences with others. Have your actions ever been judged inaccurately by a person such as a boss, a peer, or a family member? How could this experience support your thesis about whether or not attribution theory and bias affect human behaviors with organization?
    • Can self-serving, or other, bias affect one’s perception of a behavior?
  • Creative Decision Making
    • Explain how creative decision-making can improve our ability to make better decisions, considering the numerous obstacles to do so. Include an analysis about how good decision making can potentially affect productivity and job satisfaction.

Writing considerations:

  1. The introduction paragraph should introduce your topic and clearly explain what the paper will address.
  2. Headings can be used to organize your information. See templatePreview the documentView in a new window. (Each heading should include at least two paragraphs – minimum.)
  3. Each paragraph should make a point which can be linked back to your introduction paragraph. Design the topic sentence to embody what the paragraph will entail.
  4. The most important consideration in the body paragraphs is the argument that you want to develop (is or is not perceptions, attribution theory and bias applicable?) in response to the topic (applicability of perception, attribution theory and bias). This argument is developed by making and linking points in and between paragraphs.
  5. The conclusion paragraph should restate your thesis (your suggestion that perceptions, attribution theory and bias does or does not apply to human behaviors in organizations.)

Your assignment should be a minimum of five to six double-spaced pages, and should adequately discuss the topic, demonstrate maturating self-awareness, and include at least one peer-reviewed source, in addition to your text. Use the rubric to check for thoroughness. Include frequent citation to resources.

The Ashford Library should be used as your primary resource for this assignment, but other credible sources will also be accepted. Your sources should be cited according to APA format as outlined in the Ashford Writing Center (Links to an external site.)Links to an external site..

4MAT Review Instructions

The 4MAT Review is a way of responding to readings that requires the learner to interact with new ideas on several levels. Please use the following format in preparing your 4MAT Review:

1.      Summary: Summarize what you have read as if you were the author boiling down the book into 250 tight words. Prove that you comprehend the readings by writing a no-nonsense summary (picture a summary similar to reading the back cover of a book to decide if you want to read it).  **You may not use the course text book for this assignment. Any reviews submitted on the Dunbar text will receive an immediate grade of 0. The book must be written specifically regarding the subject of life coaching.

2.      Concrete responses: Get vulnerable! In 250 words, relate a personal life experience that this book connected with in your own life. Relate your story in first person, describing action, quoting sentences you remember hearing or saying. In the teaching style of Jesus, this is a do-it-yourself parable, case study, confession. You will remember almost nothing you have read unless you make this critical, personal connection. What video memory began to roll? This is your chance to tell your story and make new ideas found in the book your own.

3.      Reflection: What new questions pop up for you in response to what you have read? Keep a rough note sheet at hand as you read. Begin with questions like, “What would I like further information on?”, “Where do I not agree/strongly agree with the author?”, or “What bothers me/excites me about this content?” This section should be at least 250 words.

4.      Application: How does information book influence how you are going to continue your own personal growth process? What actions or changes are you going to make in your life as a result of your learning? Your response here is a matter of obedience first, questions later. Be precise in summarizing your action steps (limit these comments to about 250 words).

 

 

Please note: Your grade for the 4MAT Reviews depends on the quality and thoroughness of your response to each of these four headings. Please include each heading in the body of your paper.
