Unformatted text preview: ndom practice; increased (implicit) problem solving during practice Distribution (spacing) of practice Massed Rest between trials and/or sessions are very short vs. how do i spac emy practice????? Distributed Rest between trials and/or sessions are relatively long data shows that varying interval times increases practice and retention. as compared to constant interval times between sessions. Which leads to better learning? If total work periods are the same and we are referring to the spacing of practice sessions, distributed leads to better performance in practice and retention 7 7/4/12 read on own Distribution (spacing) of practice Massed vs. Rest between trials and/or sessions are very short Distributed Rest between trials and/or sessions are relatively long If total work periods are the same and we are referring to the spacing of practice sessions, distributed leads to better performance in practice and retention •  Increased fatigue in massed practice •  Decreased cognitive processing/effort in massed •  Decreased opportunities for memory consolidation in massed Distribution (spacing) of practice Massed vs. Rest between trials and/or sessions are very short Distributed Rest between trials and/or sessions are relatively long Which leads to better learning? If we are referring to rest between trials (inter-trial interval), results differ depending on type of task For discrete skills – massed may be better in retention For continuous skills distributed is better breaking the skills apaart is called fractionizing!!!!! Decomposition of a skill How do you break the skill into parts ? Segmentation Fractionizing Practice parts separately Put together when each part is learned e.g., guitar Practice part A, then B, then AB, then C, then ABC = Progressive part or chaining e.g., breaststroke Simplification A variation on whole practice, this simply reduces difficulty of the entire skill segmentation---- learn a then b then c simplification---make the skill itself easier KNOW THE DIFFERNCE BETWEEN THESE DUDE!!!!! e.g., juggling scarves 8 7/4/12 Quantity of practice Overlearning is practice which goes beyond the amount required to achieve task goals/criterion performance Overlearning assists retention (although there are limits and other performance variables have an impact): Melnick (1971) Schendel & Hagman (1982) Dynamic balance (stabilometer) Machine gun assembly and disassembly in US army Theories: Strengthens the general motor program (cognitive) Stabilizes the movement pattern (dynamic) Deliberate Practice The road to expertise? What is deliberate practice? (Training) if youa re doing something full time you are working 2000 hrs a year. •  not leisure!" •  tailored to the individual" •  best with tutor/coach" to get to be an expert you haev t opractice 10000 hrs… fucking crazy 5 yrs. •  often lots of repetition" •  requires high motivation" •  Erricsson – 10,000 hours of deliberate practice to reach expert status, regardless of genetics" 9 7/4/12 UNIT 1.4: Effects of Practice Objectives 1.  Explain the effects of the following practice variables on the learning and performance of different motor skills: a.  Variability b.  Schedule c.  Distribution d.  Amount e.  Skill decomposition 10...
