9. Speech patterns

10. Syntax

11. General mood

18. Agent’s gender

20. agreement (agent’s persuasion)

23. Congruent-mimic (reverse-mirrored)

25. warmth

26. information

29. Distance (How much does X leave you with cold feelings?)

31. Aid – obstacle : differenceOn average participants feel more using intention with an aiding agent that was facially similar. higher involvement with an aiding agent. less distant with an aiding agent.

32. To sum up, Mimicked behaviour more social presence / better impression But, If the users notice the mimicry, it does not work And, The users feel positive when just the agents are helpful.

33. Thank you EunJoung Cho
