Title: Psychology and Technology
1Psychology and Technology
- Development
- Vs.
- Evaluation
2Web-based InstructionSocial Dynamics of On-line
groups
3Conformity On-line
- Smilowitz, Compton Flint (1988)
- Repeated Aschs line experiments
- 69 vs. Aschs 29 ignored other group members
and gave a correct answer
4Group Polarization On-line
- Spears, Russell Lee (1990)
- Tendency toward Group polarization
- We are more susceptible to group polarization
on-line than off-line
5Biased Discussion in Work groups
- Hightower Sayeed (1995)
- Review of candidates resumes
- Synchronous chat and on-line voting
- Much more than F2F, on-line groups did not share
positive information about the losers, nor
negative information about the winner
6Minority Opinions in On-line Workgroups
- McLeod, Baron, Marti Yoon (1997)
- Choose company for best investment
- F2F vs. synchronous chat
- Only one member given complete information package
7Minority Opinions in On-line Workgroups
- Minority member did present opinion more strongly
than F2F minority member but was ignored by group
members - Group members perceive anonymity as the reason
the minority member speaks out

8Gender Effects
- Davis, Zaner, Farnum, Marcjun, McCarthy (2002)
- GDSS
- Discussion to generate names for videogames
Under anonymous condition- Equal contribution of
ideas for females and males
- Under identified condition-
- Females contributed less
-
- Percentage of their ideas voted for dropped
9Electronic Brainstorming
- Connolly (1997)
- When the group is large , electronic
brainstorming produces better results than F2F - On-line workgroups not susceptible to Production
blocking - Promotes disinhibition
10Trust in Virtual Teams
- Jarvenpaa, Knoll Leidner (1998)
- swift trust
- Frequent interaction
- Positive tone
- Volunteering
- Extra effort to meet commitments
11Your On-Line PersonaImpression Formation Theory
12Impression Formation Theory
- Goffman (1959)
- Sign activity of two kinds
- the expression given (verbal)
- the expression given off (non-verbal)
13Nonverbal Signs
- includes facial expression, tone of voice,
gestures, eye contact, spatial arrangements,
patterns of touch, expressive movement, cultural
differences, and other "nonverbal" acts.
14- The continuum of verbal and non-verbal behavior
(Knapp, 1997)
Intrinsic coding
Iconic Coding
Arbitrary Coding
The proximity of the code to its referent
15Types of non-verbal behaviour
- 1. Proxemics space
- 2. Kinesics movement
- 3. Haptics touch
- 4. Oculesics eye movement
- 5. Vocalics non verbal communicative aspects of
the voice - 6. Chronemics time
16Innate?
- Cross-cultural similarities in identifying facial
expression - Newborns ability to mimic facial expression
- Facial expression not different in blind children
- Babies spend more time gazing at faces that
maintain eye contact
17Non-verbal Codes
- Are frequently given more credence and are more
trusted that verbal codes - Perhaps because it is our first means of
communication
18Non-verbal codes
- Are continuous and natural
- Are immediate
- Gestural form often resembles the message content
whereas words have arbitrary meanings - (e.g., come here)
19Non-verbal codes
- Appear in clusters
- Several channels operate simultaneously and in
concert with each other - Are summative
20The social information processing (SIP) theory of
CMC
- (Walther,1992)
- communicators deploy whatever communication cue
systems they have at their disposal - When nonverbal cues are unavailable users adapt
their language, style, and other cues to such
purposes.
21On-Line impression formation
- cues that shape impressions are
- participants' screen names and descriptions
- "linguistic style" (language intensity, verbal
immediacy, and lexical diversity) - paralinguistic cues include "typographical marks
and other textual features," including the use of
capital and lowercase letters, exclamation marks,
typing errors, and emoticons
22Screen Namesand Social Categorization
- timberwolf is a broad shouldered man who wears
cotton flannel shirts with the sleeves rolled up
and likes to spend a lot of time outdoors. He
wears gold wire-frame glasses and his somewhat
unruly brown hair is starting to go gray. He's
from the Pacific Northwest so that explains the
flannel shirt, pseudo-lumberjack outdoorsman
part. The graying hair goes with his being a
professor, as do the glasses, although the fact
that they are gold wire-rim has more to do with
his name and the fact that he doesn't capitalize
it, a sort of understated elegance.
Jacobson, 1999
23Emoticons
24Acronyms
25Opportunities for misinterpretation
- In offline interaction, the meaning of "silence"
may be interpreted with reference to non-verbal
cues (e.g., facial expressions, posture,
gestures, proximity), - "response latency" (Lea Spears, 1995, p. 218)
in computer-mediated communication may give rise
to ambiguity and alarm. - Silence may be construed as agreement,
disagreement, or indifference it may also be
taken as a sign of technical trouble
26Discrepancies between on-line and off-line
impressions
- Buford says, "Cardinal surprised me he is softer
and gentler than I expected." - R says, "What had led you to expect otherwise?"
- Buford says, "He is terse online. Since I was
asking mostly dumb questions about how to do
things in the virtual community, I felt I
annoyed him or he made me feel as if I were
annoying him, when it was just his online
directness. He always answered, but sometimes
quite briefly... like 'try help'
Jacobson, 1999
27More opportunities for misinterpretation
- It takes about 4 to 5 times longer to exchange
messages in computer-mediated communication than
in face-to-face communication (Walther, 1996), - people attempt to sustain the flow of interaction
by typing briefly and quickly taking turns in
communicating. - people are "multitasking" and manage diverse
demands on their time and attention by responding
briefly and at irregular intervals.
