, & Pellegrini, 2003 ). Physical self-perception is another important correlate of PA behavior ( Raudsepp, Liblik, & Hannus, 2002 ). Physical self-perception plays an important role in motivation and participation in PA ( Bryant, James, Birch, & Duncan, 2014 ; Jaakkola, Sami, Anthony, & Jarmo, 2016 ), and is

We introduce a two-perception probabilistic concept of adaptation (TPPCA), which accounts for fast and slow adaptation processes. The outcome of both processes depends on the perceptual difference (termed herein a quantum) of how an individual perceives his or her abilities, skills, and capacities (βv) to interact, cope, and perform a given task (δi). Thus, the adaptation process is determined by (βv – δi). Fast adaptation processes target aspects that require immediate responses while slow adaptation processes involve ongoing adaptation to long-term demands. We introduce the TPPCA in several domains of inquiry, which rely on fast adaptation processes (perceptual–cognitive–action coupling, performance routines, psychological crisis, reversal states), slow adaptation processes (i.e., career aspirations, burnout), and processes that can be either fast or slow (i.e., flow, affect and mood changes, emotion regulation).

Objectives:

To examine gender and ethnicity differences in adolescents’ physical activity (PA) behavior and perceptions.

Methods:

Surveys designed to measure PA behavior and perception were completed by 175 adolescents. Gender and ethnicity differences in PA behavior were examined using chi-square tests. A two-way between groups MANOVA was used to examine perception.

Results:

No significant differences were found between gender groups for PA. Caucasian students were more likely to be active and to perceive that PA makes their health better. Hispanics were more likely to perceive that PA requires more time than Caucasians.

Conclusions:

Findings suggest greater consideration be given to the ethnic orientation of PA behavior antecedents when promoting PA to adolescents.

One study determined the relationship between coaches’ perceptions of exertion and measures taken by heart rate monitors and accelerometers during the training of 31 elite junior soccer players ( Brink, Kersten, & Frencken, 2017 ). Coaches based their perceptions

Successful decision-making when blocking requires exceptional levels of two performance elements, perception–action coupling and

Considerable research about self-perception has been conducted to understand its nature and associations with other health-related variables such as the practice of physical activity or fitness level ( Welk & Eklund, 2005 ). Despite its universal application in scientific literature dealing with

According to the Perception-Action-Model (PAM), the human visual cortex consists of the ventral vision-for-perception and the dorsal vision-for-action streams. Performance decrements with increasing variation of nominally task-irrelevant stimulus features (Garner-Interference) was suggested as an empirical tool for identifying contributions of these streams: vision-for-perception, but not visionfor-action, should suffer from Garner-Interference, but inconsistencies in this argument were revealed by several studies. We here used a new manipulation to induce Garner-Interference in a dorsal task: The stimulus objects did not differ in their lengths but in the side to which they were weighted. In Experiment 1, Garner-Interference was found in a ventral perceptual judgment task. Notably, we did also find Garner-Interference in skilled right-handed grasping in Experiment 2. These findings suggest that the presence or absence of Garner-Interference does not consistently index the contribution of different processing streams for perception and action, but the coprocessing of nominally task-irrelevant stimulus features in general, be it for perception of action.

In association football, the flash-lag effect appears to be a viable explanation for erroneous offside decision making. Due to this spatiotemporal illusion, assistant referees (ARs) perceive the player who receives the ball ahead of his real position. In this experiment, a laboratory decision-making task was used to demonstrate that international top-class ARs, compared with amateur soccer players, do not have superior perceptual sensitivity. They clearly modify their decision criterion according to the contextual needs and, therefore, show a higher response bias toward not responding to the stimulus, in particular in the most difficult situations. Thus, international ARs show evidence for response-level compensation, resulting in a specific cost (i.e., more misses), which clearly reflects the use of particular (cognitive) strategies. In summary, it appears that experts in offside decision making can be distinguished from novices more on the cognitive or decision-making level than on the perceptual level.
