- Continuous
- age related
- sequential
relitively permanebt gains in motor skill capability associated with practice or experience
the neural , physical, and behavioral aspects of movement
Quatitive increase in size or body mass
qualitive advance in biological makeup; cell, organ, or system advancement in biochemical composition
process occurring with passage of time leading to loss of adaptability or full function and eventually to death
- individual constaints; stucturale and functional
- enviromental constraints
- task constraints
- discorage or limit certain movements
- encourage or permit other movemnts
- shape movement- channel away from some movements while toward others
related to body's structure: height, muscle mass
related to behavioral function: attention, motivation
properties of the enviroment:

we can plot the change in behavior or overtime or age: time age horizontal axis, behavior on vertical axis
individual or group is observed over time
- study canrequire lengthy observation
individual or groups of differents ages are obseved
- change is inferred not actually observed
aka mixed longitudinal
- mini longitudinal studies with overlapping ages
