Perceptual alteration refers to any change in how an individual perceives the world around them. This can encompass modifications to sensory input, cognitive processing, or the subjective experience of reality. Such alterations can be temporary or persistent and can arise from a variety of sources, including physiological changes, psychological states, or external influences.

Physiological causes for perceptual alteration include drug use, brain injury, or neurological conditions like epilepsy. Certain substances, commonly known as hallucinogens or psychedelics, are well-documented for their ability to induce profound changes in perception, often leading to altered sensory experiences such as intensified colors, distorted shapes, or the perception of things that are not present. Neurological disorders can also disrupt the brain's ability to process sensory information correctly, resulting in hallucinations, illusions, or a distorted sense of self and environment.

Psychological factors can also significantly influence perception. Intense emotions like fear or stress can heighten sensory awareness or lead to misinterpretations of stimuli. Conditions such as schizophrenia are characterized by significant perceptual disturbances, including hallucinations and delusions. Furthermore, attentional biases, expectations, and prior experiences all play a role in shaping how individuals interpret sensory data, meaning that perception is not a passive reception of information but an active construction.

External influences, such as sensory deprivation or overload, can also induce perceptual changes. Prolonged exposure to monotonous environments can lead to a fading of perceptions, while overwhelming sensory input can cause confusion and disorientation. Techniques like meditation and mindfulness aim to alter perception by fostering a different awareness of sensory experiences and internal states, often with the goal of reducing stress or increasing self-understanding. Understanding perceptual alteration is crucial in fields ranging from neuroscience and psychology to art and philosophy.
