The visual information relevant to perform a task or motor skill is detected before the last phase of the shot [14; 15]. [PERSON] [4] defined that relevant visual information as the QE, that is, the part of the final fixation that begins during the preparation phase and is offset when the QE falls off a location for more than 100 ms. The QE can, therefore, carry through arm flexion and extension phases. The fixation has to be at least 100 ms long and it should not move more than 3\({}^{\circ}\), representing the minimum amount of time needed for a concrete action of motor control. According to this definition, QE is regarded as an important perceptive characteristic [16], as it may be considered a perception-action variable, with its start depending on the beginning of a motor action [17]. Therefore, QE is the period that starts during the preparation phase and ends when the fixation falls off of that location for more than 100 ms. The QE can therefore carry through arm flexion and extension phases. The fact that QE precedes the beginning of the movement indicates that this last fixation is used to process and define the action parameters [18]. The QE process is implicit to the performance of experts in a vast range of shot actions [19]. Longer QE periods are associated with better performance levels, and also with faster skill acquisition [20; 21], as they provide the time needed for the brain to organize the neural structures that underly action planning and control [22]. Therefore, QE may be considered as an integral part of specialized motor activities [23; 24]. The QE of experienced players is significantly longer than that of novice players [8]. Experienced players are able to fixate on objects in advance and for longer periods than less experienced ones, regardless task conditions [8; 16]. This fixation duration is even longer for converted shots than for failed ones [25]. During the QE period, the brain has time to process the visual information enabling the experienced player to have more time to program the motor skill, allowing a better performance or better decision-making [26; 27]. However, [PERSON] et al. [28] highlighted that despite longer fixations being associated with better motor programming, they only occur in conditions where both player and target are stationary. This is refuted by [PERSON] et al. [29], when claiming that the QE concept also expands to the motor performance in dynamic game situations. Broadly, a recent review of studies underlined the importance of isolating which QE period contributes more to performance in the three-point shot [21]. High-level motor task success is dependent on a long fixation of a specific location before a specific phase of the movement. This location, however, is not consensual across the literature [21]. In basketball, the shot is the most important technical element of the game. The jump shot is a specialized dynamic motor skill that is the result of a combination of balance, strength, technique [30] and visual information [2]. This type of shot involves a motor pattern that is different from the set shot [31], presenting some advantages such as: (i) greater execution speed, (ii) better ball protection and (iii) greater precision at different distances [30]. Hence, changes in the players' visual field may also interfere with how the player gathers relevant information during task performance [7]. This assumption partially supports this research. It is important to consider that the neural efficiency hypothesis states that the brains of experienced players are faster and more efficient in the execution of the task [8; 32; 33]. In this perspective, the visual patterns of experts will be more efficient and research that fits in the expert vs. non-expert paradigm may be useful. In terms of visual tracking during the basketball jump shot, some studies use this approach [4; 11; 29].
