          1. Repeating previous action even though now out of context
            1. Egocenticism- toy found because of action not thought
    2. Bower et al - 2 mth appeared to expect train to emerge
      1. Gaze pattern Suggests they knew it still existed whilst out of sight
        1. Study did not need physical capabilities
          1. Further study show baby continue to track train after stopped
            1. Suggests baby can't stop tracking once started
      2. Baillargeon et al
        1. 5 mth, rotation of drawbridge, impossible event & novel event
          1. Baby showed more interest when block did not obstruct when it should have- impossible
            1. Novel event, rotation stopped by block
              1. Suggests they believe block exists & understood it should be obstacle
                1. Replicated at 6-8 mth
                  1. More attention paid to habituated but impossible event
                    1. Car emerging in a road block condition, knew car should not get through

            2. Hood & Willats
              1. 5 mth, more likely to reach in direction of interesting object seen before lights out
              2. Harris, delay in searching A not B task
                1. Memory for new hiding place fragile & short delay disrupts
                2. Butterworth
                  1. Error still made with transparent cloth
                    1. 2 ways to code position, when objects moved
                      1. Egocentric code- position in relation to self
                        1. Allo centric code- position in relation to another object
                          1. If toy moved but not cloth, only one code has changed
                  2. Diamond
                    1. Vary length of delay
                      1. Better able to cope with age as short term memory improves
                        1. Suggests when info from temp memory fades, habitual response takes over
