Your final grade in this class will depend on your performance in the following areas:

Class exams: 40 points (4 × 10 pts each)

There will be 4 class exams on the dates specified in the schedule. Each exam will consist of short-answer questions about the course content covered since the previous exam.

You must arrive on time for exams. Students who arrive more than 10 minutes late for an exam will not be allowed to sit the exam.

Final exam: 15 points

A cumulative final exam will be held during finals week. As well as contributing 15% to your overall grade, your score (%-correct) on the final exam will automatically replace any and all class exam scores that it beats.

You must arrive on time for the final exam. Students who arrive more than 10 minutes late for the exam will not be allowed to sit the exam.

Homework assignments: 15 points (5 × 3 pts each)

There will be 5 short written homework assignments during the semester (the due dates are shown on the class schedule — assignments will be posted at least one week before the deadline). The deadline for homework assignment is 11:59pm on the due date.

Reading assignments: 10 points

You are required to read the assigned textbook chapter before we cover that topic in class.

For each reading assignment, first read the chapter and then answer the on-line quiz on that chapter. The quizzes consist of multiple-choice questions and are administered via the web site for this course — http://faculty.plattsburgh.edu/steve.mansfield/205F12reading.asp.

You are allowed to refer to the book when you answer the quiz. In order to receive credit for the assignment you are required to score at least 50% on the quiz. You may retake the quiz as many times as you like, so long as you score at least 50% correct before the deadline.

APA lab report: 15 points (draft: 3 pts; final version: 12 pts)

The class will perform a study during through the semester. You will each write a complete lab report (in APA style) for this study.

A draft of your paper is due by 11:59pm on Friday November 9th. Once I have received your draft you must arrange to meet with me so that I can give you feedback. I will have a sign-up sheet on my office door where you can choose a meeting time (these meetings will be scheduled starting on Monday November 12th).

The final version of your APA paper is due by 11:59pm on Monday December 10th.

Final project: 5 points

Towards the end of the semester you will split into small groups to develop and run a new and exciting research project of your own. Each group will give a 10-minute presentation to the rest of the class describing the research question, rationale, findings, and conclusions from its final project.

Extra credit

Extra credit can be earned in the following ways:

Personal Reactions (0.25% each. Maximum 6)
Write a 1-page report (approximately 300 words) that describes how the material presented in a specific class was personally relevant to you. For example: What did you learn from a class? Did the material conform to your understanding of the world, or did it challenge your beliefs or opinions ... etc.?
To submit a personal reaction for extra credit follow the REACTION link once you have logged into the course web site. Your reaction must be sent within one week of the day the class was given, and you must have been present in class on that day.
Error spotting (0.1% each. No limit)
I hold you all to a high standard for accurate spelling and correct grammar. It is only fair that I should be held to the same standard. So, if you find a spelling error or a grammar error in any class materials that I distribute to you, or post on class web pages, or in a course textbook, and you are one of the first students to report it to me, I will reward you with extra credit.
To report an error for extra credit follow the ERROR REPORT link once you have logged into the course web site. Your error report must be sent within one week of the day the material was distributed (or referred to) in class, and you must have been present in class on that day. Additionally, your error report must itself be free of errors in order to receive extra credit.
Participation in research
Psychology department faculty often invite students to participate in their research projects. I will announce to the class when any such opportunities become available. I will post instructions in the extra credit portion of the course web site. The amount of extra credit that will be awarded for participating in a study is commensurate with the anticipated effort you will be required to make (extra credit is typically awarded at a rate of 1% per hour). If you only complete part of a study, your extra credit will be pro-rated according to the extent of your participation. For example, if a study involved four 15-minute sessions, but you only attended two of them, you would only receive half of the announced extra credit — probably 0.5% in this case.
For each research participation opportunity, I will also offer an alternative assignment, comparable to the research experience in time and effort, to students who are ineligible, unable, or unwilling to participate in the research project. Students will have the option of gaining the extra credit by participating in the research OR by completing the alternative assignment. Details of the alternative assignment will be posted in the extra credit portion of the course web site.
These policies are in accordance with the Psychology Department's guidelines for awarding extra credit to student research participants.


Your letter grade will be determined according to the following table.

≥ 93A
≥ 90 and < 93A−
≥ 87 and < 90B+
≥ 84 and < 87B
≥ 81 and < 84B−
≥ 78 and < 81C+
≥ 75 and < 78C
≥ 72 and < 75C−
≥ 69 and < 72D+
≥ 63 and < 66D
< 63 E

The final application of these guidelines is subject to the discretion of the instructor.

Note: Except for the extra-credit opportunities stated in this syllabus, students will not be allowed to do any additional "extra work" to make up for poor performance in class.


Your attendance is required and will be recorded at every class. If you are absent from class you will miss important course content and class activities (which will make it hard for you to complete the homework assignments.)


Course web site

I make extensive use of my class web site for this course.

You can login in to the class website using the "student login" on my homepage: http://faculty.plattsburgh.edu/steve.mansfield. Enter your last name in the "last name" box, and your password into the "password" box. Your password will be initially set to your Banner ID number (you should change your password once you have logged in.)

You will need to use the class web site to access all the course materials, to submit homework, to send in extra credit assignments, and to review your grades.

You must check your grade page at least once a week.

If you are unable to access the class web site you should contact me.

Academic honesty

It is expected that all students enrolled in this class support the letter and the spirit of the Academic Honesty Policy as stated in the college catalog.

All cases of suspected academic dishonesty will be reported to the college judicial board in accordance with the college's procedures for addressing suspected academic dishonesty.

Penalties for dishonest conduct will be determined on a case-by-case basis.
