Chapter VII - SensesChapter VII - Senses
Psychology of Alcoholism, The by George Barton Cutten (1874 - 1962)
This chapter presents a detailed, scientific account of how alcohol damages the senses, especially sight, and how these changes can lead to hallucinations and distorted perception. It draws on medical cases and experiments to show the central and peripheral nerve effects behind vision loss, strange sounds, altered taste and smell, and abnormal skin sensations.

How Alcohol Warps Your Senses: Sight, Sound and Sanity
Episode Overview
- Chronic alcohol use impairs every major sense, with sight being the most severely affected through optic nerve damage and retinal changes.
- Alcoholic amblyopia and related colour vision problems, especially with red and green, pose serious safety risks in jobs that rely on signal recognition.
- Hearing is less damaged at the ear itself but frequently disturbed at the brain level, leading to buzzing, phantom sounds and later hallucinations.
- Distorted smell, taste and touch can trigger fears of poisoning, crawling sensations on the skin, and other experiences that feed delusions.
- Experiments with small doses of alcohol show an initial brief increase in sensitivity followed by a clear drop in accuracy across several senses.
“All perception is interpretation.”
How do different strategies aid in addiction recovery? This chapter heads straight into the science, looking at how alcohol steadily interferes with every sense and, in turn, with sanity and daily functioning. Rather than stories or chatty conversation, you’ll hear a structured, almost forensic walk-through of what long-term drinking does to the body and brain.
The focus lands first on sight, described as the sense that “suffers the most.” You’ll hear about optic nerve damage, colour vision loss, central blind spots and why railway companies became so strict about alcohol use once they realised how common red–green signal problems were in drinkers. The episode breaks down medical case reports and experiments, from early eye tests with tiny doses of alcohol to tragic examples of blindness caused by stronger alcohols like methylated spirits.
Hearing, smell, taste and touch are then examined one by one. Alcohol’s role in strange noises in the ears, buzzing, phantom bells and voices is laid out, along with how these can grow into hallucinations and persecutory ideas. Smell and taste distortions are linked to food paranoia and fears of poisoning, while skin sensations such as burning, pins and needles, or the feeling of insects crawling are shown as common starting points for frightening beliefs.
Throughout, the style is formal, clinical and heavily referenced, aimed at people who want clear medical and psychological detail about alcohol’s impact rather than personal stories. A core idea runs through it all: “All perception is interpretation,” so once alcohol harms the nerves and brain, no sense can be trusted fully. For anyone curious about the hard science behind how alcohol can twist reality itself, this chapter offers plenty to think about.
How might understanding these physical effects change the way you look at alcohol use and its risks?
