Group work: integral to organizations
• Increasingly, organizations are relying more and more on group work
• Broad technology choices in organizations

The role of proximity in collaboration
• Proximity leads to collaboration because it fosters informal communication (Hagstrom, 1965)
• Allen (1977): if you’re farther away than 30 meters from a colleague, you might as well be several miles away
• Dormitory residents most likely to form friendships when they live in close proximity
![Page 5: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/5.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Study to test questions about proximity
• 70 semi-structured, hour long interviews with scientists in 3 fields
• Survey of 66 psychologists• Archival study of 93 members of a large organization• Data collected:
– Whether each possible pair of 93 researchers (4278) published a research report
– Proximity in terms of the org chart– Physical proximity– Research similarity

Informatics 153 – Fall 2008 – Gillian Hayes
Role of similar interests?
Perhaps researchers with similar interests have offices near each other?
But this doesn’t explain it fully
Proximity provides opportunity for informal interaction
![Page 7: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/7.jpg)

What does informal communication do?
• Proximity leads to frequency of communication– As distance between people increases, phone
communication does as well (Mayer, 1976)
– Same relationship with electronic messages (Eveland & Bikson, ‘87)
• Perhaps people close to each other like each other more (Zajonc, 1968)

Physical proximity related to frequency of communication in planning and writing stage of research
![Page 9: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/9.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Quality of communication
• Proximity leads to communication that involves more than one sensory channel
• “Richer” communication can enable researchers to develop ideas, find common interests
• Which stage of research do you think has the most frequent communication?
![Page 10: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/10.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Cost of communication
• Proximity enables – “low-cost” communication– quick interactions
• Time savings– For information workers, time is the scarcest
resource
![Page 11: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/11.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Communication technology requirements
Communication tools for planned and unplanned interactions in same and different times
• Coordination and management tools
• Task-oriented tools to integrate products
Typically most tools support only a single type of process
![Page 12: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/12.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Tools can facilitate unplanned interactions at a low-cost
• As with proximity, tools need to provide frequent communication
• Maintaining and building shared knowledge
• Provide backchannel and feedback mechanisms
![Page 13: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/13.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Technology and feedback
• What is backchannel response?• What does it do?• What happens without feedback?
– Multi-channel communication can lead to a lack of feedback, not knowing who might be talking
Emoticons can be used for spontaneous feedback, but are limited :-), LOL, IMHO
![Page 14: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/14.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Communication technologies enable different feedback• Webcams, video-conferencing
• Teleconferencing

Attributes of Group Behavior
• Cohesiveness• Egocentrism• Extremitization• Groupthink (Janis, 1972)
Name some consequences of bad group decisions
![Page 20: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/20.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Face to face and Electronic Groups
• Face-to-face groups often have predictable behavior
• Electronic group behavior is less predictable
![Page 21: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/21.jpg)
Laboratory studies vs. naturalistic observation
![Page 22: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/22.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
E-groups: more equal participation
• In 3-person electronic groups, each member tended to talk 1/3 of time
• Status cues missing in e-groups
![Page 23: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/23.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Flaming
• Groups tend to make more extreme (risky) decisions than individuals
• Electronic discussion-more likely to result in flaming behavior– Expt.: 102 flaming remarks vs. 12 in f2f (24 meetings)
• Electronic groups reduce conformity
![Page 24: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/24.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Decision quality• Impacts of high status people
• Who is risk seeking and who is risk averse?
• E-groups– will consult more people– ignore faulty reasoning of those with good social skills or high
status– May experience more conflict– Make riskier choices
![Page 25: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/25.jpg)
Informatics 153 – Fall 2008 – Gillian Hayes
Time to decisions
• Takes four times as long for e-groups as f2f (3-person groups)
• Decisions by e-groups that were rushed were more extreme
• Faster decisions not necessarily better
![Page 26: Group Dynamics](https://reader035.vdocuments.net/reader035/viewer/2022081603/568137f4550346895d9fb5d0/html5/thumbnails/26.jpg)

Electronic group dynamics
• Technology can change the dynamics of a group
• Moreover, particular kind of computer media can affect group communication
• Organizational/management policies can be used to guide dynamics
