Physiological Barrier

Physiological Barriers to Effective Communication

Physiological barriers—one of numerous barriers within the subclass of intra-personal barriersOpens in new window—are caused by the individual’s own personal discomfort such as sensory dysfunctions.

This may occur on the part of the receiver or the sender.

Physiological barriers often result from performance characteristics and limitations such as low memory, poor concentration, mental dullness and dysfunction of the sensory organs like eyes, ears, nose, etc.

For a person who is not able to speak, hear or see, certain alternative communication options and methods should be adopted to make communication possible.

For instance, in a classroom, the same message (say, a PowerPoint presentation) delivered by the same professor may be differently received by a student with poor eyesight and another with good eyesight.

However, this barrier can be overcome by providing suitable visual aids—spectacles or contact lenses for example—to that student, or allowing them to sit closer to the speaker.

Physiological barriers may result from any of the following conditions—vision impairment, hearing impairment; speech disorders such as stammering, apraxia and dysarthriaOpens in new window; dyslexiaOpens in new window (a range of learning difficulties related to the written word); or aphasia (a disorder that results from damage to portions of the brain that are responsible for language).
