2 Hvorfor tror du at grupper er godt for kreativitet? 3 Ved implementering (Coch & French 1948) Gruppedeltagelse reducerer modstand Reducerer NIH attitude (not invented here) 4

3 Kognitiv stimulering i grupper er vigtig (Brown, Tumeo, Larey & Paulus 1998; Paulus 2000; Paulus, Larey & Dzindolet 2000) Paulus, P. B., Larey T. S., & Dzindolet, M. T. (2000).

Small Group Research, 29, MEN Grupper genererer væsentlig færre ideer end det sammen antal individer, der arbejder alene (Mullen, Johnson & Salas 1991; Diehl & Stroebe 1991) Grupper genererer dårligere ideer end individer, der arbejder alene (Brown & Paulus 1996) Diehl, M. & Stroebe, W.

4 Hvorfor tror du at grupper er skidt for kreativitet? 7 Reducerer standarden for hvad man kan snakke om (Parlof & Handlon 1964) Dårligere ideer på grund af social matching (Brown & Paulus 1996) 8 Brown, V; Paulus, P.

5 Individer overvurderer deres kreative bidrag i gruppearbejde (Paulus, Dzindolet, Poletes, & Gamacho 1993) For meget fokus på at anvende egen viden, fremfor at kombinere viden imellem gruppedeltagere (Stasser 1999) Konkurrence mellem at generere egne ideer og at lytte til andres ideer (Mulligan & Hartman 1996) 9 Mulligan, N. & Hartman, M.

Journal of Personality and Social Psychology, 65, Ofte domineret af en eller to i gruppen, og meningsløs argumentering kan ofte lede til fastlåste situationer (Nunamaker, Dennis, Valacich, Vogel & George 1991) Følger den hierarkiske, faglige eller sociale leder (Finkelstein 1992) 12 Finkelstein, S.

7 Større grupper mindsker kreativitet for prisen for at være anderledes (original) er højere Socialt press kan ende med at man acceptere andres ideer (Janis 1982) 13 Janis, I. L. (1982).

Kaufman & Robert J. Sternberg, The Cambridge Handbook of Creativity. Cambridge: Cambridge University Press Disse faktorer leder til en dårlig start på gruppearbejde Den langsomme start skaber en nedadgående social spiral som kan skabe en langsom kultur i gruppen (Camacho & Paulus 1995; Paulus & Dzindolet 1993) 14 Paulus P.

8 Brainstorming og lignende metoder ser ud til at have fejlet Paulus og Yang foreslår en ny model til gruppearbejde: A Brain-writing - Attention - Incubation model (Paulus & Yang 2000) 15 Paulus, P. B. & Yang, H. (2000). Idea generation in Groups: A basis for creativity in organisations, Organizational Behavior and Human Decision Processes, 82, Brain-writing - Attention - Incubation model 1. Individuel idegenerering (brain-writing) 2. Roter ideerne og alle læser hinanden ideer for inspiration (attention) 3. Individuel idegenerering uden rotation (incubation) 16

9 Vigtige lærestreger for gruppearbejde Erstat meget af den verbale interaktion med skriftligt arbejde (Nunamaker, Briggs & Mittleman 1995) Det meste af kreativ arbejde er udført individuelt Interaktion for at lave kognitiv stimulering - IKKE for idegenerering 17 Nunamaker, J. F., Jr. Brigs, R. O. & Mittleman, D. D. (1995). Electronic meeting systems: Ten years of lessons learned. In D. Coleman & R. Khanna (Eds.), Groupware: Technology and applications (pp ). Saddle River, NJ: Prentice Hall. Individuel brainstorming er bedre end gruppe brainstorming (Furnham & Yazdanpanahi 1995) Individuel idegenerering skal være efterfulgt af gruppebrainstorming - ikke den anden vej rundt (Finke & Ward 1992) 18 Furnham, A., & Yazdanpanahi, T.
