A physical body as a whole is assumed to have such quantitative properties as mass, momentum, electric charge, other conserved quantities, and possibly other quantities. An object with known composition and described in an adequate physical theory is an example of physical system.
It is something, usually a physical object, which takes the place of the mother-child bond. Common examples include dolls, teddy bears or blankets. Donald Woods Winnicott introduced the concepts of transitional objects and transitional experience in reference to a particular developmental sequence. With "transition" Winnicott means an ...
There are two definitions of object. The first definition holds that an object is an entity that fails to experience and that is not conscious. The second definition holds that an object is an entity experienced. The second definition differs from the first one in that the second definition allows for a subject to be an object at the same time. [3]
The process of perception begins with an object in the real world, known as the distal stimulus or distal object. [3] By means of light, sound, or another physical process, the object stimulates the body's sensory organs. These sensory organs transform the input energy into neural activity—a process called transduction.
In metaphysics, phenomenalism is the view that physical objects cannot justifiably be said to exist in themselves, but only as perceptual phenomena or sensory stimuli (e.g. redness, hardness, softness, sweetness, etc.) situated in time and in space.
Object permanence is the understanding that whether an object can be sensed has no effect on whether it continues to exist. This is a fundamental concept studied in the field of developmental psychology , the subfield of psychology that addresses the development of young children's social and mental capacities.
An object at some distance from an observer will reflect light in all directions, some of which will fall upon the corneae of the eyes, where it will be focussed upon each retina, forming an image. The disparity between the electrical output of these two slightly different images is resolved either at the level of the lateral geniculate nucleus ...
Psychology is the scientific study of mind and behavior. [1] [2] Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social ...
