When we aren’t paying attention to something, we won’t process it Late filter: Even if you aren’t paying conscious attention to something, it can still affect you o Stroop task Dual Tasks and Limits of Attention o Shared pool (capacity model) o If the tasks share processing resources (structural limits) o Central processing (1 thing at a time) o Divided attention

Task switching (incurs a switching cost) Subliminal Perception o Backwards masking o Priming- direct vs. indirect measures o Dissociation paradigm Objective vs. subjective threshold o Implicit perception o Déjà vu Attention Selections o Space vs. objects o How do we pay attention? Covert/overt (sequential attentional hypothesis) o How do we orient? Volitional (paying attention on purpose) Reflexive (overrides volitional, such as a loud noise or a flash of light). Eye Movement o Saccade (jerk, fast) o Smooth Pursuit (following a moving target object). o Fixation (on fovea, stationary object) o Physiological Nystagmus (tiny saccades the eye makes so that the image on the retina doesn’t fade). o Regression (when reading, “jumping back” to an already read section) o Moving window technique (a method that allows the study of eye movement). Chronometrics: Response times (RTs) and Accuracy Levels o Attended stimuli have smaller RTs than unattended. o Attended stimuli have higher accuracy levels than unattended. Model Tasks o Two types o 1) Non-informative cue (i.e. reflexive) Short SOA: Valid response time faster than invalid RT Long SOA: Valid RT slower than invalid RT o 2) Informative cue Short SOA: no different in RTs for valid/invalid Long SOA: Valid RTs are faster. Visual Search o Individual features o Conjunctions o RSVP: time course of visual processing Attentional blink: decreased ability to name the second target when the 2 targets are within 200-500 milliseconds of one another. When Attention is broken…

o Hemispatial neglect: damage to the (right) parietal lobe, causes neglect of the contralateral hemisphere of the body. o Balint’s syndrome: bilateral damage causes space to disappear Only 1 object can be processed at a time. Chapter 5: Memory Traces and Schemas Ebbinghaus and Memory o Nonsense words, the Ebbinghaus forgetting curve. Showed that people’s memory for nonsense words dropped drastically in the time immediately after they learned it, but then remained relatively stable over time. o Effectiveness of various learning techniques, especially distributed vs. mass practice (lesson learned here- cramming is terrible for your memory). Now-Print theory & Flashbulb memories o Criteria for flashbulb memories Surprising (we pay attention to them) Importance (we rehearse them, talk about them with family and friends, see it in the media, etc.) o The now-print theory implies that we photocopy the memory in our minds and have a copy available to draw forth into consciousness.
