Example: Add Touch
Grandmother Workman lurched over and grabbed the pale skin of Randal's thin forearm with her leathery hand. The folds and creases beneath her skin coiled themselves out like electrical wiring, like the bloated, roughly-textured relief map of the world that his mother just posted above his bedside table. Randal looked ahead toward the winding spiral staircase, fidgeted with a small hole in his baseball jersey, and bit his lip. His mouth filled with the sweet, coppery taste of blood as she leaned in closely toward him, breathing her hot breath on the damp hair at the base of his neck. She smelled of wet cigarettes and bacon. As they slowly climbed the long, steep staircase, the only sound was his grandmothers' labored breathing and the mournful creak of the wooden stairs.
Comment: The sense of touch encourages us to investigate the world around us by feeling it and learning the texture, shape, and size of things. Tactile images can be powerful sensory triggers. They allow a reader not only to visualize a scene, but to experience it. Inclusion of the sense of touch prevents the reader from remaining distanced or detached from the writing.
In the sample text, the sense of touch has been engaged through allowing the reader to recreate a primary sensation: the feel of a person's breath on the back of his or her neck. This is a sensory experience that most people have encountered. Therefore, through recalling familiar tactile sensations the writer encourages the readers to put themselves in the place of the characters.
