PSYC212 Lecture Notes - Lecture 4: Mental Models, Affordance, Peer Group
Document Summary
Cognitive ergonomics: the study of the mental processes involved in the interaction between humans and technology. Affordance: (cid:449)hat a(cid:374) o(cid:271)je(cid:272)t (cid:272)a(cid:374) do i. e. it(cid:859)s properties. Mapping: refers to the relationship between different parts of a system or between controls a(cid:374)d the (cid:396)esults. (cid:862)natu(cid:396)al mappi(cid:374)gs(cid:863) = good spatial relationship between the layout of the controls and the things being controlled. Population stereotypes = the common expectations about the effects of an action. These e(cid:454)pe(cid:272)tatio(cid:374)s a(cid:396)e (cid:374)ot (cid:862)ha(cid:396)d(cid:449)i(cid:396)ed(cid:863) (cid:271)ut a(cid:396)e i(cid:374) fa(cid:272)t a(cid:272)(cid:395)uired through experience and are often (cid:272)ultu(cid:396)e spe(cid:272)ifi(cid:272). E. g. (cid:272)lo(cid:272)k(cid:449)ise fo(cid:396) o(cid:374); do(cid:449)(cid:374) to s(cid:449)it(cid:272)h (cid:858)o(cid:374)(cid:859) a(cid:374)d up fo(cid:396) (cid:858)off(cid:859). Under stress people tend to revert to stereotypes. The relationship between controls and displays varies in terms of compatibility. We find it easier to operate devices when the controls are compatible with our expectations of how the thing should operate.
