[1] The concept emerged in the context of sports training and sports psychology, as one of a set of attributes that allow a person to become a better athlete and able to cope with difficult training and difficult competitive situations and ...
Impact tests on natural materials (can be considered as low-strength), such as wood, are used to study the material toughness and are subjected to a number of issues that include the interaction between the pendulum and a specimen as well as higher modes of vibration and multiple contacts between pendulum tup and the specimen.

Izod impact tester in Blists Hill Victorian Town. The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the ...
Examples of order effects include performance improvement or decline in performance, which may be due to learning effects, boredom or fatigue. The impact of order effects may be smaller in long-term longitudinal studies or by counterbalancing using a crossover design.

Charpy test sample with a notch In mechanical engineering and materials science , a notch refers to a V-shaped, U-shaped, or semi-circular defect deliberately introduced into a planar material. In structural components, a notch causes a stress concentration which can result in the initiation and growth of fatigue cracks.
1.1 White-noise stimuli Stevens' power law is an empirical relationship in psychophysics between an increased intensity or strength in a physical stimulus and the perceived magnitude increase in the sensation created by the stimulus.
Figure 1 from The Block-Design tests by Kohs (1920) showing, in grayscale, an example of his block test. [1] The Kohs Block test, also known as the Kohs Block Design Test, [2] is a performance test designed to be an IQ test. The test taker must, using 16 colored cubes, replicate the patterns displayed on a series of test cards.
