sensory selection (filtering, focusing, automatic switching)
response selection (response intention, initiation and inhibition, active switching, and executive supervisory control)
attentional capacity (structural and energetic capacity, arousal, effort)
sustained performance (fatigability, vigilance)
working memory is concieved of as a limited-capacity store for retaining information over short term (seconds to 1-2 minutes) and for performing mental operations on the content of this store.
the contents of working memory may originate from sensory inputs but also may be retrieved from long term memory.
working memory allows information to guide behaviour in the absence of external cues and ensures that information will be available until it can be effectively encoded into long term memory.
explicit (conscious or declarative) memory-refers to intentional or conscious recollection of previous experiences.
implicit (unconcious or nondeclarartive or procedural) memory-refers to a heterogeneous collection of abilities (e.g. priming, skill learning or procedural memory, habit formation) that are manifested across a wide range of situations.
the identification of objects abbreviated as "what" ( visual )
spatial processing of objects abbreviated as "where" ( spatial )
receptive language vocabulary
lexical retrieval ability
Right-Left orientation-discrimination of right from left
tactile form recognition, memory for shapes and spatial location
activities of daily living typically known as ADLs, which focus on primarily on overlearned self care activities such as feeding, bathing, toileting and basic mobility.
instrumental activities of daily living, commonly known as IADLs, which are viewed as involving fairly complex cognitive abilities and include activities such as managing medication, finances and household duties.
the IADLs are of primary interests in test assessment.
