1. Evaluate James Gibson’s central claims on visual perception and state at least two different applications of these ideas to real-world tasks.
James Gibson argues that perception cannot be subjected to hypothesis testing as it is direct. According to Gibson, there is an adequate amount of information in the environment to make sense of the world around us. His theory, also known as ecological theory, provides a comprehensive analysis of how perception can be explained and its relation to the environment. Gibson's central theory implies that perception involves natural methods influenced by growth with no learning necessary and that perception can be described exclusively so much as the weather. Gibson assessed the sensory system and concluded that it develops conscious visual discernment without any psychological influences or managing.
Applications to real-world tasks
Structure Constancy- This is the capability to understand that a structure would retain the same
compositional structures across various geometrical changes. A structure,
shape, or construction would remain the same even if subjected to different
geometrical changes such as pivots. An important factor to consider is
structure constancy is viewer-centered and depends on the viewer's perceptions
in relation to the environment.
Visual discrimination- the ability to perceive details in visual elements. There are
various activities that a person can engage in to help them develop visual
discrimination skills. For instance, students are encouraged to match photos,
letters, and words with other objects and materials. In most cases, students
will match the words with the objects they have perceived in their environment.
