1. perceptual

   Perception (from Latin perceptio 'gathering, receiving') is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system. Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves. Perception is not only the passive receipt of these signals, but it is also shaped by the recipient's learning, memory, expectation, and attention. Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). The process that follows connects a person's concepts and expectations (or knowledge), restorative and selective mechanisms (such as 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. Since the rise of experimental psychology in the 19th century, psychology's understanding of perception has progressed by combining a variety of techniques. Psychophysics quantitatively describes the relationships between the physical qualities of the sensory input and perception. Sensory neuroscience studies the neural mechanisms underlying perception. Perceptual systems can also be studied computationally, in terms of the information they process. Perceptual issues in philosophy include the extent to which sensory qualities such as sound, smell or color exist in objective reality rather than in the mind of the perceiver.Although people traditionally viewed the senses as passive receptors, the study of illusions and ambiguous images has demonstrated that the brain's perceptual systems actively and pre-consciously attempt to make sense of their input. There is still active debate about the extent to which perception is an active process of hypothesis testing, analogous to science, or whether realistic sensory information is rich enough to make this process unnecessary.The perceptual systems of the brain enable individuals to see the world around them as stable, even though the sensory information is typically incomplete and rapidly varying. Human and other animal brains are structured in a modular way, with different areas processing different kinds of sensory information. Some of these modules take the form of sensory maps, mapping some aspect of the world across part of the brain's surface. These different modules are interconnected and influence each other. For instance, taste is strongly influenced by smell.

1. perceptual

   Perceptual refers to the ability or process of understanding and interpreting sensory information or stimuli received from the environment through senses such as sight, hearing, smell, touch, and taste. This process involves the brain interpreting and making sense of this sensory data, allowing us to perceive the world around us. It's associated with cognition, awareness, understanding, interpretation, recognition, and judgement.

Examples of Perceptual in a Sentence

1. Debasish Mridha, M.D.:

   Happiness is a perceptual reality, not an absolute certainty.

2. Jeff Goldblum:

   At the beginning of the day, I remind myself: free association, stream of consciousness, perceptual readiness and then openness, this whole business of acting and music seems to be, if nothing else, an invitation toward opening up. Opening yourself up in both directions. Not only to what’s around you in reception but then in your giving back, reacting and offering something.

3. John Gilmore:

   Truth: the most deadly weapon ever discovered by humanity. Capable of destroying entire perceptual sets, cultures, and realities. Outlawed by all governments everywhere. Possession is normally punishable by death.

4. Jerald Podair:

   There is some sort of huge perceptual chasm between the police and the policed in most American cities, when you get that kind of perceptual gulf -- when you're looking at the same incident and you're interpreting it in different ways -- that's a recipe for total division and complete disunity in our society.

5. Ichiro Kobayashi:

   We aim to understand how the brain represents information about the real world, toward such a goal, we demonstrated that our algorithm can model and read out perceptual contents in the form of sentences from human brain activity. To do this, we modified an existing network model that could generate sentences from images using a deep neural network, a model of visual system, followed by an RNN (recurrent neural network), a model that can generate sentences. Specifically, using our dataset of movies and movie-evoked brain activity, we trained a new model that could infer activation patterns of DNN from brain activity.
