Visual perception of the physical stability of asymmetric three-dimensional objects.

Perception of the physical stability of asymmetrical three-dimensional objects

Visual estimation of object stability is an ecologically important judgment that allows observers to predict the physical behavior of objects. A natural method that has been used in previous work to measure perceived object stability is the estimation of perceived “critical angle” – the angle at which an object appears equally likely to fall over versus return to its upright stable position. Fo...

The Effect of Motor Dependent/Independent Visual Perception Training on Visual-Motor Integration and Fine Motor Skills of 7-8-year-old Children: The Retest of Movement Hypothesis

The purpose of this study was to examine the effect of motor dependent/independent visual perception training on visual-motor integration and fine motor skills of 7-8 year old children .For this purpose, 107,  1st grade  primary school students in Sabzevar were selected through purposive sampling (with equal economical and cultural status , optimum mental and physical health and full sight with...

Comparison of Functional Stability of Shoulder Girdle between Individuals with Symmetric and Asymmetric Scapula

Background and Aim: Changes in the position of the scapula due to its multiple roles, including acting as a muscle binding site and stabilization in this area can reduce the physiological and biomechanical efficiency of the shoulder, which ultimately increases shoulder injury. Therefore, the purpose of this study was to compare the functional stability of shoulder girdle between asymmetric and ...

Visual search for type of motion is based on simple motion primitives.

Can we search for items based on their type of motion? We consider here visual search based on three types of motion: (i) ballistic motion, in which objects move in a straight line until they encounter a display boundary; (ii) random-walk motion, in which objects change direction randomly; (iii) composite motion, in which objects move with random fluctuations around a generally ballistic trajec...
