Activities and Exercises

Lost on the Moon Task - Marianne Miserandino shares her version of the Lost on the Moon task. The first link is to her handout describing how she runs the activity in her class. Here is the actual moon problem to be solved by a group. Here are the answers to the moon problem. [added 2/19/14]

The Cave Rescue Mission - group decision making task provided by Valerie Pruegger [added 2/19/14]

Hidden Profile Task - Dana Wallace offers these PowerPoint slides he uses for a group decision making task. Dana states "I’ve tried to get a hidden profile task to work in the classroom before, but the students were so excited to talk to each other that they disclosed all information! Now I use powerpoint of Jack and Jill to show the same points of how different decisions can be made based on information available." If you would like more information on this task, you can reach Dana at dwallace@jc.edu. [added 2/19/14]

Group polarization - This activity mirrors closely some of the original work when we were referring to it as "risky shift." [added 2/19/14]

Social Loafing - To introduce the topic of social loafing I sometimes divide my class in half. I have one side of the room individually make a list of as many uses they can think of for an automobile tire. I tell them that anything is acceptable. The other half of the room works as a group (or two groups if too large) on the same task. Not surprisingly, the individual side generates far more uses per person than does the group side. Of course, there are a lot of reasons for that, which we discuss. But one of the reasons is social loafing. [added 2/19/14]

Social Loafing - At the end of our discussion of social loafing, I divide the class into small groups to work on the following problem: Use the conditions research has identified that increase or decrease the likelihood of loafing in a group to identify strategies for managing workers at a fast food restaurant. [added 2/19/14]

Social Facilitation - To introduce the topic of social facilitation I ask for two volunteers who are willing to do a little math. (Not many takers for that one!) I have one volunteer stay at his/her desk and have the other volunteer come to the blackboard. I give them both the same multiplication problem (e.g., 8,347 x 348) to solve as quickly as they can. The student at the desk usually gets the wrong answer. The person at the board almost always gets the wrong answer. It provides a good example of all the different theories of social facilitation such as evaluation apprehension and distraction conflict. [added 2/19/14]

The "O" train: Teaching the power of ostracism - Lisa Zadro and Kipling Williams use this in-class activity to "show students the powerful consequences of ostracism firsthand using an engaging, validated teaching tool: the "O" train." This activity was awarded an honorable mention in the Social Psychology Network's inaugural Action Teaching Award program. [added 4/6/06]

Are more heads better than one? - Dave Myers passed along this good in-class demonstration. He refers to James Surowiecki's book, The Wisdom of Crowds, in which the author makes the point that groups can make better decisions than the average individual under certain conditions (e.g., "given freely contributed inputs from varied perspectives" -- Myers). This point can be illustrated in class using the "jelly bean challenge." As Dave suggests, "The idea would be to

* have individual class members estimate the number of beans.
* average those estimates.
* ask for a show of hands from people who were closer to the correct answer--2845 beans--than the class answer.

The anticipated result would be few hands raised, thus illustrating that, as the text will say, 'all of us together can become smarter than almost any of us alone.'" Other related questions could be explored by such variations as dividing half the class into small groups to reach a group decision about the number of jelly beans and leaving the other half to make individual judgments. [added 1/13/06]

Class Assignments

Projects

Group Dynamics course - Here is a unique approach to teaching a group dynamics course with some experiential assignments. Here is a link to an observation assignment in which students analyze the group dynamics of a classroom. This link takes you to an assignment in which a small group observes the dynamics of another group anywhere they find one. [added 9/25/10]

Group project: Investigate an organization - In his Social Psychology of Organization course, Richard Hackman requires his students to participate in a semester-long project which involves "the collection of data about one or more actual groups that operate in organizational settings." [added 11/11/03]

Group presentations: Jonahue! - While knocking around in Don Forsyth's site, I couldn't help remembering the times I taught Group Dynamics many years ago (using Don's excellent text). So, bear with me as I reminisce and share a rather odd class assignment. I was looking for some way for my students to learn about group dynamics while working in groups, and at the same time I wanted to develop their oral speaking skills. But I didn't want them to give the usual oral presentations in which they delivered a prepared speech. They got enough of that (or at least some of that) in their other courses. I wanted them to learn to speak extemporaneously and knowledgeably about a topic. So, I asked myself, where do we find experts speaking publicly extemporaneously? One venue I thought of was the talk show. Sometimes experts are invited to come on a talk show, not to give a speech, but to answer questions. At the time, one of the talk shows doing this was hosted by Phil Donahue. My first name is Jon, and, voila... "Jonahue" was born! Each week I turned my Group Dynamics classroom into a talk show. I, Jonahue, was the host. A group of three students was "invited" to be the guests on the show because they were experts (if they prepared well) on a particular group dynamics topic. More specifically, the group was there to use its expertise on the topic to apply it to a specific topic-related problem. The other members of the class were the audience and were required to ask questions. As host, I also asked questions. And, I recorded my wife asking questions I prepared for her that I played during class as if she were a live caller to the show. Each group of three students went through this ordeal three times during the term. It was fun! And, more importantly, I think it worked. [added 3/6/02]

Deindividuation

Deindividuation - This link suggested by Steve Jones includes lots of good examples of deindividuation. More examples here. [added 2/19/14]

In class we discussed that being in a group leads to deindividuation. I recently watched the movie "To Kill A Mockingbird." In it, there is a scene where a mob has gathered at the jail. They want to lynch a black man who they believe has raped a white woman. The men in the mob are acting together in a ugly unison of threats and violence until the little daughter of the man trying to stop the mob speaks up. She calls out to one of the men in the mob by name, reminding him who she is, reminding him of his visits to their house, reminding him that she plays with his son, etc. The man finds these statements embarrassing. They increase his self-awareness and strip away the mob mentality that he was a part of. He can no longer hide behind the mob as the blame for the violence. He now can see the responsibility on his shoulders not just diffused on others. All of this causes him to announce in a loud voice that he's leaving and thinks the other mob members should do the same, which they do.

A couple weeks ago I chaperoned a trip to Bloomington for the ISU high school marching band competition. My son's last words as we got to the high school were, "Dad, please don't embarrass me by yelling at everyone on the bus." Much to his delight I was assigned to another bus. I'm sure that each of these band members individually are fine young persons. But nowhere has deindividuation been more obvious than on that bus. Screaming, yelling, climbing over seats, and general mayhem seemed to be the order of the day. Keeping in mind what my son had said, I tried a little informational influence to get them to conform to the rules. I tried to explain how they might get hurt climbing over the seats, and how they needed to rest and conserve energy to be at their best for the competition. That didn't work very good. I didn't think normative influence would work because the group norm seemed to be acting wild and crazy. I concluded that authority influence was the only way. Several loud "SIT DOWN AND SHUT UP's" did the trick.

Social Loafing

I used to do a lot of singing. I sang in choirs, quartets, trios and did solo performances as well. Mostly in church settings, but I also did solo work when I sang in the work choir. Since I was the soprano with the highest range, the other members depended on me to carry the high notes. If I didn't hit them, nobody did. I found that after several performances, my voice would begin to show the strain and it became necessary for me to conserve it. Therefore, when we were singing in an average range, I would only mouth the words. I could do this because I knew that the others would continue to sing. However, as we approached the bars that I was to sing, I found that the crescendo of all of our voices together helped me to do a better job. That was not the case when I sang in smaller groups. When I was the "only" soprano, social loafing was not allowed. If I hadn't sung every note, the harmony would have been badly distorted. Not wanting to experience their disapproval or our mutual humiliation, I had a greater incentive to do my part.

In my Industrial Labor Relations class, we are currently doing a group project. The class is divided into two sides, 8 people on the management side, and 12 people on the union side (I'm on management). What we are trying to do is to renegotiate the labor contract between a union and a slaughter house (that is in financial trouble). This class has brought to light many examples for me to write about. The first one that comes to mind deals with social loafing. In both groups, it is present. But, after a talk with a friend on the union team, I found out that it is more prevalent on their team. This is probably due to their larger number. What also encourages this is that we are graded as teams, and the teacher never even looks up unless someone makes reference to a chart. Unless the teacher remembers the voices of the people who spoke, those who didn't will remain anonymous. A third factor that encourages the social loafing is that on both sides, there are people who really want to get good grades (me among them). The other side has two people in particular that I know desperately want an A so much that they seem to be doing the whole project. On our side, pretty much everyone wants an A, and only 1 person could be accused of social loafing (missed two important classes and does as little as possible).

Tomorrow's election affords the perfect opportunity for social loafing, and unfortunately, many people take advantage of it. The group goal is to elect qualified leaders of our choice. People tend to have less accountability and less identifiability. Next year if our leaders are doing a poor job, we can say, "I never voted for that jerk!" or "Yes, I voted for that jerk, but so did a million other people!" This allows us to diffuse our individual responsibility. Or I could tell myself that my one little vote isn't going to make any difference in the election, so why should I bother to vote at all?

It has been proven that under certain situations we are more likely to loaf. Boy, it sure is easy to loaf when you're at work. One way I noticed that my manager has tried to reduce loafing at work is by goal setting. Since I work in retail - the more we sell, the more we make! Commission is very important to all of us at work -- and it seems most of us always try to sell as good as we can -- so our reward is very nice at the end of the month. Not only does this goal setting make a profit for the employees who show the effort -- but it is also profitable for the company. I think accountability and identifiability is very important. I want to be noticed at work when I sell a three thousand dollar ring -- and when I stay after hours to help clean up -- and I want the people who choose to "loaf" to be noticed too -- and believe me -- they are!

Debriefing after a task improves team effectiveness

Alcohol and group formation - "Sayette and his colleagues assembled various small groups using 720 male and female participants, a larger sample than in previous alcohol studies. Researchers assessed individual and group interactions using the Facial Action Coding System (FACS) and the Grouptalk model for speech behavior. They concluded that alcohol stimulates social bonding, increases the amount of time people spend talking to one another, and reduces displays of negative emotions. According to Sayette, the paper introduces into the alcohol literature new measures of facial _expression_ and speech behavior that offer a sensitive and comprehensive assessment of social bonding." [added 12/24/12]

Going with the social flow - "The key finding is that the participants in the high interdependent condition were rated as more joyful than participants in the low interdependence condition, based on self-report and on scores given by trained observers who watched their facial expressions and body language."

Ostracism

"Children's and teenagers' reasons for excluding others" - "Eighty-four children were interviewed: 28 7-year-olds, 28 11-year-olds and 28 17-year-olds. A clear difference emerged with age. The younger children rarely described themselves as having any choice when they'd excluded others. They mostly mentioned practical reasons - 'We were playing piggy-back wars ... another kid wanted to play ... we didn't have any more people for him,' or peer pressure - 'We were playing jump roping and somebody else wanted to play with us, but then my friend said no.' Their pleas of innocence contradict behavioural observations showing that young children often leave other kids out deliberately. The 17-year-olds, by contrast, were more up front, most often giving the reason that they disliked the excluded person - 'We didn't invite this one girl because she's not open-minded ... ,' was a typical comment." [added 12/24/12]

Acetomeniphen reduces pain of social rejection - Yep, soon there will be a pill for everything. Apparently, "social rejection and physical pain really do share some of the same brain circuits." The first link is to the journal article; the second link is to a blog entry about it. [added 7/21/10]

"Does social exclusion literally feel cold?" - "In another experiment, instead of relying on volunteers' memories, the researchers triggered feelings of exclusion by having the volunteers play a computer-simulated ball tossing game. The game was designed so that some of the volunteers had the ball tossed to them many times, but others were left out. Afterwards, all the volunteers rated the desirability of certain foods and beverages: hot coffee, crackers, an ice-cold Coke, an apple, and hot soup. The findings were striking. As reported in the September issue of Psychological Science, a journal of the Association for Psychological Science, the "unpopular" volunteers who had been ostracized during the computer game were much more likely than the others to want either hot soup or hot coffee. Their preference for warm food and drinks presumably resulted from physically feeling cold as a result of being excluded." [added 4/25/09]

Cyberball! - Kipling Williams offers downloads of Cyberball, "a virtual ball-toss game that can be used for research on ostracism, social exclusion, or rejection." Could also possibly be used for lab activities. [added 1/8/06]
