Smartphones has become a more integral part of everyday life, holding more capabilities of enhancing critical cognitive processes, if not entirely replacing them. With the ability to act as a telephone directory, appointment scheduler, tip calculator, navigator, and gaming device, smartphones appear capable of doing an unlimited number of cognitive activities and satisfying a significant number of our affective demands on our behalf.Cognitive failures are frequently characterized by attentional gaps and are thought to be common in daily living. These attentional deficits may be caused by endogenous processes like ruminations or daydreaming or exogenous factors like distracting stimuli. 

Smartphones have a tendency to immediately capture the attention of those engaged in an activity that is unrelated to the smartphone. A three-second distraction such as reaching for a cell phone is sufficient to divert attention away from a cognitive task, and it has been demonstrated that the mere possession of a smartphone has a detrimental effect on working memory capacity, fluid intelligence, and attentional processes.Excessive use of smartphones has been associated with several negative consequences for individuals, such as limitations in decision-making skills, problem-solving, attention, memory, executive controls, and reaction time.

Therefore, there is a need to find the impact of smartphone use on cognition in young adults, to understand how smartphones impact us to take the required precautions to avoid harmful outcomes.
