Groupware. Old wine in new bottles. Or…You plus Me less Them = US. Agreement. Many real life tasks are “equivocal”, i.e. have no best or correct answer Unless the group “enacts” agreement, it cannot act So agreement is a critical group output Distinct from task performance.

Groupware Old wine in new bottles Or…You plus Me less Them = US
Agreement • Many real life tasks are “equivocal”, i.e. have no best or correct answer • Unless the group “enacts” agreement, it cannot act • So agreement is a critical group output • Distinct from task performance brianwhitworth.com
Why is agreement important? No Group Action The Group Acts! brianwhitworth.com
Computer Mediated vs FTF Groups • Task performance as good or better than FTF • Generally less agreement than FTF • Generally less decision confidence • Slower acting (take longer) • Lower process satisfaction brianwhitworth.com
Media Richness Theory • A physical approach, i.e. rich communication requires a high physical bandwidth for high information transfer • Ambiguous social situations require high information transfer to “disambiguate” them • CMI agreement is low because “rich” social influence cannot squeeze through the “lean” electronic channel brianwhitworth.com
Aims • Examine assumptions behind media richness approach • Propose an alternative “cognitive” or human process based perspective • Explore some implications brianwhitworth.com
Assumptions of MR I. Media richness defines communication richness II. Richness is a primary property of media III. Information exchange reduces ambiguity IV. Personal interactions give group cohesion brianwhitworth.com
Task Information Social Information I. Media richness defines communication richness • Computer channels are too “narrow” to transmit rich social influence Computer Channel brianwhitworth.com
Findings • Lean, text based e-mail is very friendly • -Email can be more friendly than face-to-face • Online groups behave like face-to-face groups (norms, jargon, roles, identity) • Some CM groups report more agreement than face-to-face • CM groups polarize brianwhitworth.com
A cognitive perspective • Meaning is a cognitive overlay on physical reality Cognitive Process Physical signal Meaning A lean message can have a rich meaning brianwhitworth.com
Contentanalysis He is not angry I AM NOT ANGRY! Context analysis He is angry Multi-Threading • Multiple cognitive processes can operate on one physical signal Messages carry content and context (sender) information brianwhitworth.com
II. Richness is a primary property of media • That media can be classified according to their richness or bandwidth • Often audio is the most efficient • E-mail is preferred to telephone for some tasks • Media cannot be arranged along a single dimension for all tasks brianwhitworth.com
Many properties of media • Number of channels • Channel bandwidth • Interactivity • Synchrony/asynchrony • Transmission cost • Linkage Comparing FTF & Computer interaction is to confound variables brianwhitworth.com
Incomparability of environments • Groupware is a communication environment • The FTF environment is the physical world • Cannot judge one environment by the criteria of another • Often cannot convert activities from one environment to another • We adapt to environments brianwhitworth.com
Underwater • Translate: Walking - slow • Adapt: Swimming - better • Invent: Flippers - best ... brianwhitworth.com
No “best” environment • No best groupware configuration • Different configurations favor different purposes (contingency theory) • Implies need for software flexibility, which people can adapt to their needs brianwhitworth.com
III. Information exchange reduces ambiguity? • “Equivocal” tasks are invariably those where personal relationships are important (e.g. getting to know someone, resolving a personal disagreement, negotiating, firing someone) brianwhitworth.com
Relating • Involves the cognitive entity “relationship” • Operates differently from task information analysis • Interactive - turn based, time sequential • Signed - not anonymous • Genuine and spontaneous • Ambiguity brianwhitworth.com
Relating and ambiguity I hate McDonalds In relating, ambiguity is a social lubricant Maybe Want to go out to McDonalds? Great! Or perhaps Luigi’s? brianwhitworth.com
An unexpected conclusion • Maintaining relationships may be as important as task analysis & completion • Face-to-face interaction may be preferred in situations where relationships are important because it allows more ambiguity, rather than less • Cannot just consider task purpose brianwhitworth.com
B A D C IV. Personal interaction creates cohesion Group cohesiveness involves interpersonal attraction, social presence, and hence rich cues (Hogg, 1992) brianwhitworth.com
Two processes - Bales IPA Socio-emotional • Interpersonal influence • Message contexte.g. voice tone Task resolution • Informational influence • Message content One communication can contain both (McGrath 1984) Group interaction has both task and social outputs brianwhitworth.com
Serious problems • Large groups are as cohesive as small ones • Cohesive group members may all dislike each other • Bales’ SE factor splits (social & emotional) • Distributed CM groups agree less when FTF • Anonymous CM groups polarize • Reducing social presence does not increase anti-normative behavior brianwhitworth.com
The influence of the group • Results can be resolved by extending Bale’s theory • Social identity theory reinvents “group” as a cognitive entity • Group influence is distinct from personal influence brianwhitworth.com
Social identity theory • Identity - the idea of “self” (a cognition) • Behavior conforms to identity • Groups form a group identity, which group members take into their own identity • Common identity gives common behavior We identify with the group, not the people in it brianwhitworth.com
Personal one-one discussion with a nutritionist for 25 minutes Directed discussion in a like group for 25 minutes Which has more effect? Radke & Klisurich, 1947 brianwhitworth.com
Normative Process • Herd behaviour? - we are group animals • Individuals adjust to group position • Mental not physical positions • Must know only: • own position • group position (majority) brianwhitworth.com
Multi-threaded communication Context: Sender state information Content: Task or factual information Position: Action or intention to act brianwhitworth.com
Example “Thanks for the great party, man!” Content: Party was great Context: Happy Position: About to leave brianwhitworth.com
Conclusions I. Meaning is a cognitive overlay II. Environments are multi-dimensional III. Relating is distinct from task information analysis IV. Group identification (which causes cohesion) is distinct from relating brianwhitworth.com
Bipolar models Task vs Socio-Emotional (Bales) Interpersonal vs Normative (Social Identity Theory) Informational vs Normative (Deutsch & Gerard,1965) Task vs Interpersonal vs Normative brianwhitworth.com
Cognitive three-process (C3P) model • Resolving the task: Informational influence • Relating to others: Personal influence • Representing the group: Normative influence All processes overlap in behavior brianwhitworth.com
Resolving the task • Individual level • One-way, one-to-many • Task information • Gives task output • Can be anonymous • Work setting brianwhitworth.com
Relating to Others • Dyadic level • Two-way, one-to-one • Sender information • Gives interpersonal output • Cannot be anonymous • Social setting brianwhitworth.com
Representing the Group • Group level • Two-way, many-to-many • Group position information exchanged • Gives a result valuable to the group • Can be anonymous • Where group action required brianwhitworth.com
Agreement conclusions • Media richness or bandwidth has little to do with generation of group agreement • Normative influence is the main generator of group agreement • Main requirement for normative influence is many-to-many linkage brianwhitworth.com
Many-to many linkage • e.g. A choir singing • Each contributes to the group sound • The communication environment merges all into one sound • Each individual hears and is influenced by the whole group Singing groups go off key together brianwhitworth.com
E-mail group discussion • Manager e-mails 20 people • Each replies to 20 people • After one interaction, could have 400 e-mails • After two rounds could have 800 • Information overload brianwhitworth.com
Electronic Voting • Computer can merge group positions by calculation • One vote can replace 400 emails for the purpose of generating agreement • As different from a “formal” vote as e-mail is from a letter • Computer makes voting easy brianwhitworth.com
An experimental test 2. Agreement requires: • No rich communication • No task information • No conflict resolution • No personal interaction 1. Agreement requires: • Rich communication • Task information • Conflict resolution • Signed interaction Enactment of agreement only requires the exchange of position information brianwhitworth.com
Treatments I. Blind II. Group aware - exchanged position information III. Group and confidence aware - exchanged position and confidence information Computer-mediated vs altered CM design brianwhitworth.com
Position information exchange AAABB Group Position: A • Three voted for A • Two voted for B • Anonymous voting brianwhitworth.com
Confidence Symbols Very Confident !! Confident ! Fairly Confident Not Very Confident ½ Not Confident at All ¼ brianwhitworth.com
Confidence information exchange A¼A¼A ¼B!!B!! Group Position: A • Three weak votes for A • Two strong votes for B brianwhitworth.com
Design Repeated measures design - every subject under every treatment brianwhitworth.com
Effect on Agreement 66% of votes unanimous 9% of votes unanimous brianwhitworth.com
“I think I agreed with most of what the group decided” Key 1 = Strongly Disagree 4 = In the Middle 7 = Strongly Agree brianwhitworth.com
Effect on Confidence Key 1 = Not confident at all 3 = Fairly confident 4 = Confident 5 = Very Confident Group position increased confidence brianwhitworth.com
Agreement was enacted without • Rich communication medium • Rich information exchange • Reasons or arguments • Personal context or social presence • Any development of trust • Any surfacing or resolution of conflict • Signed interaction (i.e. anonymously) All that was required was the exchange of position information brianwhitworth.com
Summary • C3P model suggests three purposes in group interaction: • To resolve task information • To maintain and develop interpersonal relationships • To maintain and develop group unity • The primary process generating group agreement is normative brianwhitworth.com
