The Effect of Differential Attentional Focus Strategies on the Performance of Military Elite Shooters

Table 1

The parameters used to indicate shooting performance and aim-point fluctuation.

Nomenclature
Parameter	Definition
Performance (SCATT)
Record/score	Out of a possible 10.9; high record equals performance improvement
Accumulation	Horizontal distance (mm) of shot from target center and vertical distance (mm) of shot from target center; higher accumulation means better performance
Aim-point fluctuation (SCATT)
Average fluctuations	% time, the aim point spends in the 10-scoring zone, used to indicate the accuracy of aiming; lower average fluctuations mean better performance
Stability at the target center	% time, the aiming point spends in an area of the size of the 10-scoring zone (maximum), used to indicate the steadiness of aiming; higher stability at the target center means better performance
Horizontal fluctuations	Total distance (mm), the aim-point trace moves in the (horizontal) axis; lower horizontal fluctuations mean better performance
Vertical fluctuations	Total distance (mm), the aim-point trace moves in the (vertical) axis; lower vertical fluctuations mean better performance
