Some older adults experience a deterioration in both proprioceptive sensitivity and proprioceptive acuity.

A long contralateral step facilitates trunk rotation.

Very young children’s throws tend to consist of primarily what type of action?

Assuming the sequential movements are well timed, lag in the upper arm and forearm allows momentum to be transferred from proximal body parts to successively more distal body parts, increasing the speed of movement in the more distal body parts.

New walkers need a year of walking experience before they can use the strategy of taking a step or two to regain balance when threatened to avoid falling.

Deficiencies of hormones rather than excesses of hormones disturb the normal process of growth and development.

The sound patterns to which we are exposed in infancy might be the basis for cultural preferences for certain types of music.
