Below is the data to use for answering the questions (which are below the data).

Block One (simple reaction time) --> RT = 288 ms, MT = 0, #correct = 9.6

Block Two (added movement complexity) --> RT = 313 ms, MT = 486 ms, #correct = 9.5

Block Three (more complexity) --> RT = 358 ms, MT = 641 ms; #correct = 8.4

Results from the Henry & Rogers (1960) study

Block One (simple reaction time) --> RT = 150 ms

Block Two (added movement complexity) --> RT = 195 ms (about a 20% change from simple RT)

Block Three (more complexity) --> RT = 208 ms (about a 6% change from Block Two)

1) While I provided you the MT results (and # correct) for our class data, why are we most interested in RT for this experiment?

2) Why does RT increase with each Block?
