PAD Introduction
  1. why study PAD?
    1. ageing population
      1. advance in life exp
        1. implications for finance, healthcare, retirement, technology design
        2. processing speed

          Anotações:

          • Salthouse (1996)
          1. limited time mechanism
            1. early processing takes up disproportion amount of processing time
              1. insufficient time for later stages
              2. simultaniety mechanism
                1. products from earlier processing may be lost by the time later processing is complete
                2. global vs selective slowing
                3. inhibition

                  Anotações:

                  • Hasher & Zacks (1988)
                  1. working memory
                    1. difficulty focusing on target info and ignoring/inhibiting attention to irrelevant material
                      1. internal thoughts vs external distractions
                        1. preventing off task info entering WM
                          1. deleting or suppressing marginally relevant info in WM
                            1. restrains strong response emission before suppression is evaluated
                            2. sensory functions

                              Anotações:

                              • Lindenberger & Baltes (1994)
                              1. Berling Ageing Study
                                1. age related variance in cognitive ability mediated by....
                                  1. Visual and Auditory Acuity
                              2. frontal lobe theory

                                Anotações:

                                • West (1996)
                                1. age related neural changes in frontal cortex
                                  1. PFC reduction in volume, dendritic length and number
                                    1. cognitive functions relying on frontal cortex will decline with age
                                      1. support from episodic memory, STROOP task, WM
                                      2. neural noise

                                        Anotações:

                                        • Welford
                                        1. neural circuits in the brain become increasingly noisy
                                          1. signal to noise ratio decreases
                                            1. ability to stay focused and concentrate deteriorates = deficits in cognitive performance
                                              1. parallel with inhibitory mechanism but on a neural level
