Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive functions, which are complex cognitive capabilities involving thought, planning, and problem-solving, primarily linked to the brain's prefrontal cortex.

On the other hand, automatic processes function with minimal conscious effort and do not typically disrupt other ongoing activities. For example, once a person becomes accustomed to using a smartphone, the act of texting can become automatic, allowing them to multitask effortlessly. This lower level of conscious engagement indicates that even automatic behaviors involve some level of awareness.

Between these two extremes lies daydreaming, a state characterized by low conscious effort and spontaneous emergence, often during activities that do not engage full attention. Mind wandering, a common form of daydreaming, occurs frequently during monotonous tasks, allowing people to escape into their private thoughts or fantasies. Although requiring minimal effort, mind wandering utilizes cognitive resources and is linked to the default mode network in the brain, a group of interconnected regions active during internally focused tasks.

Despite its potential drawbacks, such as reduced attention to tasks and poorer performance in educational or work settings, mind wandering offers benefits. It can provide mental breaks that aid in creative thinking or problem-solving by allowing the brain to explore and connect disparate ideas without focusing on the external environment. Understanding these different states of consciousness helps highlight the complexity of human cognition and its impact on everyday functioning and performance.
