unattended stimuli Deaf people with hearing aids § ○ Divided attention: Participants attend to all stimuli. This informs us about processing limitations and attentional capacity ○ • Objects in the real world have multiple features • Attention is the glue required for conjunctive search • Multi-tasking is divided attention • Object tracking reveals limits of divided attention •

Object tracking reveals limits of divided attention • The costs of not paying attention (bus driver, train operator, airport security scanners) What conditions lead to reduced alertness, improper selected focus, and lac vigilance in a work setting? Situations where things become automatic - too comfortable (bus driver wit the same route everyday) 1. What guidelines can reduce errors an accidents? Add variety (giving bus driver different routes) 2. • Tutorial Controlled Automatic Characteristics Slow and effortful Fast and unconscious Example Multiple choice question Someone talking in a blow horn Congruent Word reading is automatic ○ • Incongruent Colour identification requires controlled processing ○ • You would preform better on 25% congruent and 75% incongruent because you a using controlled processing to say the colour of the word With 75% congruent and 25% incongruent you would realize the colours are same at the word and you would begin rely on your automatic processing an get stooped up on the 25% of incongruent words ○ • Dual (dichotic) listening Listening to two things at once and only attending to one ○ Information → early physical filter → late semantic filter → further processi ○ Dual filter weighs information on physical cues and evaluates for meaning ○ • Single filter model Information → physical filter → further processing ○ Filtering in only the information you are attending to ○ •

Filtering in only the information you are attending to ○ Spotlight and filter models work differently: • Spotlight Filter ↑ processes of relevant information ↓ processing of irrelevant information Primarily visual cues Primarily auditory cues Ex. Shining a spotlight on computer to see it Ex. Turn off lights in the room to see computer Single and dual filter models works differently: • Single filter Dual filer ↓ processing of all unattended information ↓ processing irrelevant information Cocktail party effect Cocktail party effect and breakthrough Ex. Cocktail party Ex. Someone shouting name
