SUMMARIES
CHAPTER 13: Conscious and Unconscious Thought
- Cognitive processes happen BTS
oConscious only of products that result from mental processes – processes
themselves are unconscious
- Cognitive unconscious allows enormous efficiency – at cost of flexibility or control
oTrade-offs point the way toward function of consciousness
- Neural workspace – most processing is carried out by separate, specialized modules
oLinkage between various modules and workspace neurons – amplifies and
sustains the processing within individual modules
- Consciousness may give sense that you have adequate justification for taking an action
- Theorists argued that we distinguish types of conscious experience
oAccess consciousness how information is accessed and used within the mind
oFluency provides an intriguing hint at how we are guided by qualia and how we
can research upon it
CHAPTER 1
- Concerned with how people remember, pay attention and think
- Emerged as a discipline in 1950s
- Behaviourist movement rejected introspection as a method – that psychology speaks
only of mechanisms and processes that objective and can be open to observe
oBehaviorists perception and understanding are exactly the sorts of mental
processes that were regarded as subjective
- Psychologists focused on observable events that ask what invisible events take place to
make visible effects possible
- Working memory using evidence
oConsists of central executive and a small number of low-level assistants who
don’t really have any place other than to hold information no processing
CHAPTER 2
- Forebrain is important for cognition
oBrain damange enables us to examine what sorts of symptoms result from
lesions in specific locations
oLocalization of function
- Most of the forebrain cortex has been referred to as the association cortex – but the
area itself is divided into specialized regions
oLesions in occipital lobe lead to visual agnosia
oTemporal – aphasia
oEtc.
- Functions depends on neurons and glia
oGlia – main flow of information is carried by neurons
CHAPER 3
- Visual system – main input is from rods and cones on the retina

Document Summary
Cognitive processes happen bts: conscious only of products that result from mental processes processes themselves are unconscious. Cognitive unconscious allows enormous efficiency at cost of flexibility or control: trade-offs point the way toward function of consciousness. Neural workspace most processing is carried out by separate, specialized modules: linkage between various modules and workspace neurons amplifies and sustains the processing within individual modules. Consciousness may give sense that you have adequate justification for taking an action. Concerned with how people remember, pay attention and think. Psychologists focused on observable events that ask what invisible events take place to make visible effects possible. Working memory using evidence: consists of central executive and a small number of low-level assistants who don"t really have any place other than to hold information no processing. Forebrain is important for cognition: brain damange enables us to examine what sorts of symptoms result from lesions in specific locations, localization of function.
