A property of control processes in the modal model of memory is that they: Group of answer choices Do not require attention. May differ from one task to another. Are performed without conscious awareness. Are difficult to modify.

may differ from one task to another      

Explanation:

Modal model of memory: In psychology, the term "modal model of memory" was proposed by Richard Shiffrin and Richard Atkinson, and is described as a structural model that states three different storage systems that are being connected linearly and are associated with information processing in which information can be identified by different senses of an individual and enters his or her sensory memory and then to other stages.
