Document Summary
Independent groups factorial designs: or between-subjects factorial, both ivs are manipulated as independent groups. Within-groups factorial designs: or repeated-measures factorial, both ivs are manipulated as within groups. Mixed factorial designs: one iv is manipulated as independent groups and one iv is manipulated as within groups. Researchers were interested in better understanding how children with autism see and understand the world. Participants included children diagnosed with autism and typically developing children, who were all approximately the same age. All children were presented with several different stimuli on a large (cid:272)o(cid:373)puter s(cid:272)ree(cid:374) for up to o(cid:374)e (cid:373)i(cid:374)ute. The sti(cid:373)uli were (cid:271)oth so(cid:272)ial (cid:894)i. e. , people"s fa(cid:272)es(cid:895) a(cid:374)d (cid:374)o(cid:374)so(cid:272)ial (inanimate objects). The percentage of time children spent looking at the two types of stimuli were recorded (ranging from 0 to 100). If so, describe it: make a graph to represent the data. Any iv can have more than 2 levels: e. g. , 3 (cell phone: hands-free, handheld, no phone) x 2 (age: younger, older)
