Perception (from the Latin perceptio, percipio) is the organization, identification, and interpretation of sensory information in order to represent and understand the environment. All perception involves signals in the nervous system, which in turn result from physical or chemical stimulation of the sense organs. For example, vision involves light striking the retina of the eye, smell is mediated by odor molecules, and hearing involves pressure waves. Perception is not the passive receipt of these signals, but is shaped by learning, memory, expectation, and attention.
Perception can be split into two processes Firstly processing sensory input which transforms these low-level information to higher-level information (e.g., extracts shapes for object recognition). Secondly processing which is connected with person's concept and expectations (knowledge), and selective mechanisms (attention) that influence perception.
Perception depends on complex functions of the nervous system, but subjectively seems mostly effortless because this processing happens outside conscious awareness.
ALL ABOUT PERCEPTIONS! This video tell you all about perception, with excellent examples.

Science is a story written by installments over time, and since so much information gets updated these days. I one day found myself wondering... What is "reality"? Watch Brian Greene explain some further intriguing info at: The GOD Particle https://www.youtube.com/watch?v=d4RSbSLt24I The Elegant universe: https://www.youtube.com/watch?v=UV_X2B5OK1I Is matter all that is 'real'? ... and what are Dreams and memories? - why do they feel so real at times? One thing is for sure - change. "What is reality" might seem like a silly question given how we use our senses to interact with 'reality' everyday, but I have since arrived at ideas which I am comfortable with regarding these questions (although Im still curious). ** So heres some questions to play with - play nicely :-) ** • If...
Dan Simons explores why we see the world as it ISN'T. Daniel Simons is head of the Visual Cognition Laboratory at the University of Illinois. His research explores the ways in which our beliefs and intuitions about the workings of our own minds are often mistaken and why that matters. He is best known for his experiments revealing striking failures of perception and the limits of visual awareness. His research is exhibited in science museums worldwide and his writing has been published in many newspapers and magazines, including The New York Times, The Los Angeles Times, and The Chicago Tribune. He recently co-authored the book, "The Invisible Gorilla, and Other Ways Our Intuitions Deceive Us" (Crown, 2010). http://www.dansimons.com This talk was recorded at TEDxUIUC 2011 (02/19/11)...

Our brain constructs and shapes our reality. The importance of previous experiences and context related to how perceptions may be represented. Nikos received a PhD in Cognitive Neuroscience at University College London. He currently spends countless hours in the lab designing and running behavioral experiments combined with neuroimaging techniques (e.g. Functional Magnetic Resonance Imaging). He is seeking to understand how different types of working memory (for example visual vs. verbal) interact with attention (e.g. our ability to ignore irrelevant distracting information) to give rise to our subjective experience of the world, using healthy populations and patients (e.g. social anxiety/phobia, traumatic brain injury, Alzheimer’s). He also teaches courses related to his research in...
