Final Answer:
This type of line, where there is an impression of a continuous mark despite its absence, is referred to as an "implied" or "psychological" line.
Step-by-step explanation:
In the context of line drawings, an implied or psychological line is a fascinating artistic technique where the artist creates the perception of a continuous mark without actually drawing a continuous line. This is achieved through the strategic placement of discrete elements that guide the viewer's eye along a perceived path. For instance, in a line drawing, a series of dots, dashes, or short strokes strategically arranged can give the illusion of a continuous line when observed collectively.
The use of implied lines is rooted in the principles of visual perception and gestalt psychology. Our brains have a remarkable ability to fill in gaps and make connections between fragmented visual elements, allowing us to perceive a cohesive line where none physically exists. Artists leverage this cognitive phenomenon to create aesthetically pleasing and engaging compositions. Through careful manipulation of spacing, direction, and density of marks, artists can prompt viewers to mentally connect the dots, figuratively speaking, resulting in the impression of a continuous line in the absence of an actual unbroken stroke.
In conclusion, the concept of an implied or psychological line in art relies on the viewer's perceptual tendencies and the strategic arrangement of discrete marks to create the illusion of a continuous line. This technique not only showcases the artist's understanding of visual psychology but also adds depth and intrigue to the overall visual experience.
