Document Summary
Attention: notice or concentration, allocation of cognitive resources. Strong stimuli: bright colours, new teacher, construction sites, different artwork on the walls. Stimuli that is (cid:1684)novel in moderation(cid:1685) (only stuff they are able to understand) Procedure: children across age span shown a set of cards, told they will be tested for recall of animals only, later asked to recall household items too. Findings: across ages, recall of animals increases. From age 11, recall of household items decreases. Implications: older children better at selectively attending. Inattentional blindness: information not attended to does not reach conscious awareness and is discarded (see neisser, 1979; chabris & simons, 2010) Early selection model (broadbent, 1958), we have to select what we pay attention to. Attenuated processing model (triesman, 1969), perception is a filter to what we see. Full processing model (shiffrin et a;. , 1974), we attend to everything and decide whats relevant. Example of attenuated processing: the cocktail party effect.
