Perceptions

Our limited human perceptions accumulates visual , audio ,smell and touch informations . That will build our memory and the unconscious It will .create the thoughts , eventually be release in form of dreams and behaviors Perceptions is the root of our references and choices.erception is the process of attaining awareness or understanding of sensory information. It is a task far more complex than was imagined in the 1950s and 1960s, when it was predicted that building perceiving machines would take about a decade, a goal which is still very far from fruition. The word comes from the Latin words perceptio, percipio, and means "receiving, collecting, action of taking possession, apprehension with the mind or senses."

Perception is one of the oldest fields in psychology. The oldest quantitative law in psychology is the Weber-Fechner law, which quantifies the relationship between the intensity of physical stimuli and their perceptual effects. The study of perception gave rise to the Gestalt school of psychology, with its emphasis on holistic approach.

What one perceives is a result of interplays between past experiences, including one’s culture, and the interpretation of the perceived. If the percept does not have support in any of these perceptual bases it is unlikely to rise above perceptual threshold.

Types

Two types of consciousness are considerable regarding perception: phenomenal (any occurrence that is observable and physical) and psychological. The difference everybody can demonstrate to him- or herself is by the simple opening and closing of his or her eyes: phenomenal consciousness is thought, on average, to be predominately absent without sight. Through the full or rich sensations present in sight, nothing by comparison is present while the eyes are closed. Using this precept, it is understood that, in the vast majority of cases, logical solutions are reached through simple human sensation.

The analogy of Plato's Cave was coined to express these ideas.

Passive perception (conceived by René Descartes) can be surmised as the following sequence of events:surrounding → input (senses) → processing (brain) → output (re-action). Although still supported by mainstream philosophers, psychologists and neurologists, this theory is nowadays losing momentum. The theory of active perception has emerged from extensive research of sensory illusions, most notably the works of Richard L. Gregory. This theory, which is increasingly gaining experimental support, can be surmised as dynamic relationship between "description" (in the brain) ↔ senses ↔ surrounding, all of which holds true to the linear concept of experience.

Basic physical truths such as cause and effect and vagrant patterns imposed upon the perceived laws of creation similarly support this dualistic appreciation of reality-perception.

Additional types include:

• Amodal perception
• Color perception
• Depth perception
• Visual perception
• Form perception
• Haptic perception
• Speech perception
• Perception as Interpretation
• Numeric Value of Perception
• Pitch perception
• Harmonic perception
• Rhythmic perception

This week, is my personal study of 'perception:

Visual perception

In the case of visual perception, some people can actually see the percept shift in their mind's eye^[2]. Others, who are not picture thinkers, may not necessarily perceive the 'shape-shifting' as their world changes. The 'esemplastic' nature has been shown by experiment: an ambiguous image has multiple interpretations on the perceptual level. The question, "Is the glass half empty or half full?" serves to demonstrate the way an object can be perceived in different ways

Learning the name of a color changes the part of the brain that handles color perception.

Infants perceive color in the right hemisphere of the brain, researchers report, while adults do the job in the brain's left hemisphere.

Testing toddlers showed that the change occurred when the youngsters learned the names to attach to particular colors, scientists report in Tuesday's edition of Proceedings of the National Academy of Sciences.

"It appears, as far as we can tell, that somehow the brain, when it has categories such as color, it actually consults those categories.

Amodal perception is the term used to describe the full perception of a physical structure when it is only partially perceived. For example, a table will be perceived as a complete volumetric structure even if only part of it is visible; the internal volumes and hidden rear surfaces are perceived despite the fact that only the near surfaces are exposed to view, and the world around us is perceived as a surrounding void, even though only part of it is in view at any time.
