Abstract

Smartphones and other mobile-related technologies are commonly viewed as indispensable tools for enhancing human cognition; prolonged use of these devices may have a detrimental and long-term effect on users’ abilities to think, recall, and pay attention. The purpose of this study is to determine the effect of phone usage on people’s cognitive capacities. Excessive smartphone use may have a detrimental effect on an individual’s mental health. It has the ability to affect an individual’s memory, capacity for effective thought, and cognitive and learning capacities. The purpose of this study is to determine the effect of smartphone use on people’s cognitive abilities. Excessive smartphone use and cognitive failures were measured using the Smartphone Addiction Scale (Kwon et al., 2013) and the Cognitive Failures Questionnaire (Broadbent et al., 1982; revised by Wallace et al., 2002), which were used to collect data from 200 young adults using a purposive sampling strategy. Pearson’s product-moment correlation was used to measure the strength of the relationship between the variables, and regression analysis was used to measure the function relating to the variables. The results of the study conclude that excessive smartphone use is related to forgetfulness, distractibility, and false triggering. Hence, it can be concluded that excessive use of smartphones may be prone to cognitive failures such as forgetfulness, distractibility, and false triggering. Excessive smartphone use has been linked to a higher risk of cognitive impairment.

Introduction

The phone has grown from a device used solely for communication–calls–to a computer-replacement device capable of online surfing, gaming, instant communication via social media platforms, and work-related productivity applications. Within the last decade, the Western world has witnessed a remarkable expansion in the use of mobile technologies. While smartphones have become a more integrated part of everyday life, they have also become more capable of enhancing, if not entirely replacing, critical cognitive processes. 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.¹ While smartphones clearly keep us connected, many people have developed an unhealthy obsession with them.

Smartphones have a tendency to immediately capture the attention of those engaged in an activity that is unrelated to the smartphone.^2-4 A three-second distraction such as reaching for a cell phone is sufficient to divert attention away from a cognitive task^5, 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.^4-6 Additionally, compulsive use of these devices can cause disruptions in the workplace, school, and personal relationships when individuals spend more time on social media or gaming than on actual human interaction. Also, a recent study reveals that psychological dependence on a mobile phone diminishes the effect of smartphone presence on cognitive function.⁴

Cognitive failures are considered a normal occurrence in everyday life and typically manifest as lapses in attention. Exogenous variables, such as distracting stimuli, or endogenous processes, such as ruminations or daydreaming, may contribute to these attentional deficiencies.⁷ This distraction is detrimental to following cognitive tasks, resulting in increased errors as the distraction interval lengthens, which is especially noticeable in the classroom where students who use their phones in class take less notes⁸ and perform poorly academically.^9-10 Students at college are likely to suffer unfavorable repercussions as a result of these exogenous disruptions.^11-14 Indeed, recent research indicates that smartphone use during class and study time is distracting and reduces information retention.

Similarly, the sound of a notification from the smartphone or even the mere existence of a smartphone can impair a college student’s ability to concentrate on a lecture, and both the ringing of a cell phone during class and the mere presence of a smartphone, negatively affect college students’ performance.^10-12,15 While smartphones and other mobile technologies have the potential to alter a wide variety of cognitive areas, empirical research on the cognitive effects of smartphone technology is currently fairly limited. This is acceptable, given that technology is still continually evolving. As a result, it is critical to understand how smartphones impact us in order to take the required precautions to avoid harmful outcomes.¹ The aim of the present study is to investigate the correlation between smartphone use and different dimensions of cognitive failure in daily life among young adults.

Materials and methods

Hypotheses: Based on the review of the literature, the following alternative research hypotheses were formed:

H₁  There will be a significant relationship between smartphone use and forgetfulness.

H₂ There will be a significant relationship between smartphone use and distractibility.

H₃ There will be a significant relationship between smartphone use and false triggering.

Sample Description

An ex-post facto survey research design was used, where the researchers examined the operation of variables without manipulating them to assess the relationship between smartphone use and cognitive failure variables in young adults. A total of 200 young adult students from Chennai, India, were included in the study out of which 99 are male and 101 are female. The average was 22.54± 2.75 years. A purposive sampling technique was used in the study where participants between the ages of 18 and 35 were included, and participants above age 35 were excluded. Similarly, participants diagnosed with severe cognitive impairment and other psychiatric disorders were excluded.

Tools Used

The Smartphone Addiction Scale by Kwon et al., 2013 is a 33-item self-report measure of problematic smartphone use habits.¹⁷ The measure has a six-point Likert scale response format, with a maximum total score of 198. Responses range from “1” (strongly disagree) to “6” (strongly agree). In the initial validation research, the measure revealed a relatively good level of internal consistency (Cronbach’s alpha = 0.967). A high score implies increased smartphone use and is associated with a greater risk of smartphone addiction.

The Cognitive Failures Questionnaire by Broadbent et al., 1982,¹⁷ focuses on cognitive failures in daily life and was developed to examine cognitive failures in three critical areas: perception, memory, and motor performance. Later, researchers recognized that the CFQ has multiple additional elements, with Wallace and his colleagues presenting a four-factor solution.¹⁸ They discovered four factors: Memory, Distractibility, Blunders, and: Names. Later, Rast and his colleagues did a study and found that CFQ has three factors: Forgetfulness, Distractibility, and False Triggering.¹⁹ Subscale scores representing these aspects are obtained by adding the scores from all relevant items. The simplest way to score the scale is to add up the ratings of the 25 separate items, providing a score between 0 and 100.

Procedure

Online and offline versions of the Smartphone Addiction Scale and Cognitive Failure Questionnaire were accessible to the participants, and the participants chose whether to fill out the questionnaire online or not based on their comfort and desires. Before the questionnaire was distributed, participants signed an informed consent form, and only after consent was obtained the Smartphone Addiction Scale and Cognitive Failure Questionnaire were distributed for data collection. The participants were informed that “There is no correct or incorrect response. Kindly circle/click the values between 1 and 7 that most accurately reflects your memory assessment. Consider your options carefully and strive to be truthful. Your responses will be kept private. Kindly respond to all questions.”

Additionally, participants were informed of their choice to withdraw and guaranteed that the information gathered would be kept confidential and utilized for research purposes only. 140 individuals completed the Smartphone Addiction Scale and Cognitive Failure Questionnaire, and 60 completed the data via the Smartphone Addiction Scale and Cognitive Failure Questionnaire’s online form.

Data Analysis

Following data collection, it was analyzed using SPSS 20.0 (Statistical Package for the Social Sciences). Descriptive statistics and Pearson’s product-moment correlation were utilized to determine the strength of the association between the variables. Also, regression analysis was used to measure the function relating to the variables.

Results and discussions

Table 1: Demographic details of the participants

Table 2: Smartphone usage levels among young adults (n=200)

Smartphone usage levels are observed among young adults as the increased amount of smartphone use is associated with a greater risk of smartphone addiction. From the results, we can see that 55% of young adults’ smartphone usage is at a normal level, and about 45% of young adults’ smartphone usage is at a high level.

Table 3: Characteristics of Cognitive Failure among young adults (n=200).

Several dimensions of cognitive failure, such as forgetfulness, distractibility, and false triggering, are observed in young adults. The mean and standard deviation of forgetfulness is 14.60 ± 3.49, distractibility is 17.92 ± 3.13, and false triggering is 15.04 ± 3.27, as shown in Table 3.

Table 4: Cognitive Failure dimension scores based on Smartphone Usage levels (n=200).

According to Table 4, the most frequent cognitive failure at a high level of smartphone usage was distractibility (18.13 ± 3.10), followed by false triggering (15.07 ± 3.32) and forgetfulness (14.82 ± 3.71). Similarly, it was discovered that the most frequent cognitive failure at a normal level of smartphone usage was distractibility (17.68 ± 3.10), followed by false triggering (15.01 ± 3.23) and forgetfulness (14.35 ± 3.22).

**. Correlation is significant at the 0.01 level (2-tailed).

*. Correlation is significant at the 0.05 level (2-tailed).

Preliminary results revealed that there is a significant moderate relationship between smartphone usage and dimensions of cognitive failure (forgetfulness, distractibility, and false triggering). This indicates that forgetfulness, distractibility, and false triggering increase as smartphone usage increases. Similarly, there is a significant relationship between dimensions of cognitive failure as well. There is a significant weak relationship between false triggering and forgetfulness. In other words, when false triggering occurs, the individual tends to forget what they were remembering or were trying to recall. Similarly, there is a significantly moderate negative relationship between false triggering and distractibility. This indicates that when false triggering occurs, distractibility is reduced among individuals (Table 5). Hence, we can conclude that H₁ (There will be a significant relationship between smartphone usage and forgetfulness), H₂ (There will be a significant relationship between smartphone usage and distractibility), and H₃ (There will be a significant relationship between smartphone usage and false triggering) are accepted.

While previous studies show that cell phone addiction is related to negative emotional effects, very intermittent study has looked into the relationships between mobile phone use and cognitive outcomes related to daily cognitive functioning. The prevalence of smartphones nowadays is a topic of discussion for healthcare practitioners, mental health professionals, educators, parents, and anyone who regularly uses a smartphone. A recent study reveals that smartphone use has an effect on the brain, while the long-term ramifications are unknown.²⁰ Many people check their phones when they wake up, use them on the way to work, and keep an eye on them at all times while at work. Many people’s last sight before falling asleep is a phone screen. These habits have become so engrained in people’s lives that they rarely take a step back to assess the effects on their bodies and brains.²¹

Interaction with technology typically requires mental shifts from one context to another. Phones make individuals always available for contact and information from various aspects of life. Work-related emails, personal instant chats, social media posts, news, and entertainment are all mingled and intertwined in a never-ending stream of beeps, pings, and flashing notification symbols.²² People have evolved in various ways during the last decade to deal with this onslaught of information. The most noticeable feature is media multitasking, which involves continually juggling media and non-media tasks while often utilizing numerous digital devices linked to various internet sites.²³

Diffusion MRI was employed in a recent study to examine white matter structural connectivity, and it revealed a link between activity in the right amygdala and excessive smartphone use in adolescents.²⁴ Several reviews have been published in recent years that have evaluated the impact of whether excessive smartphone use may be considered a kind of behavioral addiction.²⁵ Studies have also investigated whether there are any distinctions between excessive smartphone use and Internet use disorder and additional research is underway.²⁶ A number of recent research have found that excessive smartphone use is related to mental health concerns and a reduction in psychological well-being. There is persistent evidence of a link between excessive smartphone use and other mental diseases, such as depression, anxiety, OCD, and ADHD, in a manner similar to the link between Internet addiction and other psychiatric disorders.²⁷

Our study was supported by previous studies indicating the possible influence of smartphone use which might have a high risk of causing cognitive failures. Though the overall correlation between smartphone use and cognitive failure domains has a significant relationship, the linear regression also predicted that smartphone use might cause cognitive failures. This study will have its uniqueness in the research area on cognitive psychology, digital well-being, and additive behaviors towards technology.

The study’s findings can serve as a guide and source of evidence for developing and implementing pertinent intervention strategies aimed at reducing cognitive failure issues and excessive smartphone use, which have a detrimental effect on mental health and cognitive performance, thereby alleviating the burden on family caregivers, the healthcare system, and society as a whole. However, the number of participants analyzed in this study was adequate for the problem we investigated, considering this as pilot work. However, future studies should focus on larger participants with various geographical locations, ages, gender, and working style that might influence the predictors and relationships between the variables.

Conclusion

This study establishes a link between excessive smartphone use and forgetfulness, distractibility, and false triggering. According to this study, need-based smartphone use may be causing cognitive failure in young individuals, including forgetfulness, distractibility, and false triggering. Excessive smartphone use has been linked to a higher risk of cognitive impairment.
