How the Apple Watch Shapes Psychology

Introduction

As technology advances and becomes deeply integrated into modern life, examining how these innovations impact human psychology is crucial. It is often assumed that humans choose to interact with technology and use the devices to fulfill a particular task or purpose. However, more reflection has been needed on the ways technological devices interact with humans for the purpose they were engineered to accomplish. At the intersection of this synergy, resides the product of wearable technology. Wearable technology bridges the gap between physical and digital worlds using real-time data collection and interactive feedback. Wearable technology has been around since the early 21st century, however, the rise of these innovations began around 2014 with the popularity of FitBits (Laricchia, 2014). In 2015, the Apple Watch was released establishing itself as the major competitor to Fitbit. It quickly overtook Fitbit with its advanced ability to measure physiological data and provide feedback, along with promoting mindfulness in a sleek and accessible design. A survey conducted on smartwatch and fitness tracker users between October 2022 and September 2023 found that 59% use an Apple Watch compared to 27% for FitBit (Richter, 2023). By 2023, Apple will become a leading market vendor for the smartwatch market in the world accounting for 22% of shipments in the second quarter of 2023 (Dayaram, 2023).

In light of the popularity and dominance of the Apple Watch technology, this paper is a literature review focusing on how it influences human behavior, cognition, and emotional well-being. Specifically, it explores why and how people adopt and use this technology, as well as the psychological impacts it has on its users. By reviewing research in health psychology, cognitive psychology, and social psychology, this review highlights the reciprocal relationship between humans and technology. By understanding these dynamics, psychologists, and engineers can address the challenges and opportunities presented by wearable technology.

Background Definitions

To generate a comprehensive understanding of how Apple Watch influences human behavior, it is critical to define what wearable technology exactly is. According to Shen et al., (2017), “Wearable technology comprises all products that can be worn on a user’s body to integrate computing with their daily tasks and activities.” Apple Watch technology includes optical heart monitors, calorimetry trackers, and fitness data, to provide instant feedback to their users (Using Apple Watch to Measure Heart Rate, Calorimetry, and Activity, 2024).

Additionally, research surrounding the Apple Watch builds on several psychological models and theories. One significant concept associated with wearable technology is self-determination theory. Self Determination Theory is used to describe the way humans are motivated by autonomy, competence, and relatedness (Nuss & Li, 2021). For instance, if a person feels like they have control over their behavior it will satisfy their need for autonomy. Competence is the desire to improve skills and master their behavior and relatedness is the need to feel socially connected to other people. When these needs are fulfilled, motivation can manifest in multiple forms: intrinsic motivation, amotivation, and extrinsic motivation. Intrinsic motivation is the most autonomous form of motivation, which is driven by enjoyment and inherent satisfaction in the activity itself (Nuss & Li, 2021). Amotivation refers to when a person is fully disinterested in an activity (Nuss & Li, 2021). Extrinsic motivation is driven by external factors, such as rewards (Nuss & Li, 2021). Similarly, the Expectation Confirmation Model focuses on the factors that drive users’ satisfaction and their decision to keep using a product (Siepmann & Kowalczuk, 2021). For example, if the device’s performance meets or even exceeds the expectations of the user and the user believes that the device is useful, then they are more satisfied, thus resulting in continuance engagement.

Specifically, when talking about wearable technology, Goal Pursuit Motivation is another important concept. Goal Pursuit Motivation refers to the drive a person has to achieve a desired end state, particularly with health and fitness (Siepmann & Kowalczuk, 2021). This influences both behavior and decision-making, especially when combined with active feedback and tracked progress provided by technology. Next, Self Quantification Behavior is the process by which an individual is provided with personal data and trends for them to reflect on to drive self-improvement (Siepmann & Kowalczuk, 2021). The Quantified Self is considered to be the product driving this behavior, which is the quantitative data that is logged through wearable technology (Pardamean et al., 2020). The last concept to highlight is the Activity Adequacy Mindset, which refers to how an individual perceives their activity level as adequate or inadequate. Regardless of the actual level of physical activity they are engaged with, the Activity Adequacy Mindset influences their psychology by tapping into not only their self-esteem but also their physiological health and lifestyle behaviors (Zahrt et al., 2023). For example, they may change their diet or exercise routines.

Integration of the Apple Watch

The Apple Watch was introduced as Apple’s “most personal device ever,” (Apple, 2014) gaining the attention of tech-savvy individuals and fashion-conscious consumers. The ability to customize the product with different watch faces, bands, and case materials allows buyers to personalize its aesthetic to match their taste. The health-focused features, such as activity monitoring and workout tracking catch the fitness enthusiasts and encourage the broader audience to live healthier lifestyles. As described in the Apple Watch’s first press release, this product was “designed to help motivate [individuals] to be more active throughout the day,” and highlights metrics such as heart rate, calories burned, brisk activity, and standing frequency (Apple, 2014). Goal-setting software is also integrated to help the user to set realistic goals and provides fitness rewards after completing each milestone to generate inspiration (Apple, 2014).

Adaption and Usage

Following the release of the new product in 2014 exhibits the first phase of the Technology Hype Cycle discussed in class. This product launch generates user interest and enthusiasm for Apple Watch technology. At this point in the Hype Cycle, people’s expectations are incredibly high, and it is up to their satisfaction with the product after using it. A study conducted by Siepmann and Kowalczuk (2021), uses the Expectation Confirmation Model to describe the factors that contribute to continuous usage of the device. In their study, a sample of 335 smartwatch users completed a questionnaire to measure their satisfaction with and continued use of their watch. Using established scales, the questionnaire inquired about satisfaction, confirmation, perceived usefulness, and enjoyment, which was adapted to the smartwatch context using a seven-point Likert scale. Their hypotheses relating to the Expectation-Confirmation Model were supported by their results: satisfaction positively affects continuance intention, confirmation positively affects satisfaction and perceives usefulness, perceived usefulness positively affects satisfaction, and perceived usefulness positively affects continuance intention. Their findings demonstrate how users are likely to adopt and use their Apple Watch. A component of satisfaction was also attributed to the design of the Apple Watch and its ability to use haptic notifications or “nudging” to engage users (Asimakopoulos et al., 2024). Their study used 2-week digital diaries of 10 participants, and surveys of 330 users to answer one of their research questions of if users feel motivated by the alerts provided by Apple Watch. They found that by being able to customize and control the nudges, users’ satisfaction is enhanced. This directly relates to the Self-Determination Theory of motivation since the customization allows people to practice autonomy, thus resulting in enhanced satisfaction and continuous usage of the Apple Watch.

Affordances

The device itself was intentionally designed to be a watch so that the technology that is integrated can accurately collect physiological data. The arteries in the wrist provide strong heartbeat signals, but are hard to reach, so Apple engineers needed to design specific motion technology that optimizes factors like LED distance, light wavelength, and band tightness (Using Apple Watch to Measure Heart Rate, Calorimetry, and Activity, 2024). The designs of the sensors, the back of the watch’s crystal shape, and material control for the light spread ensuring accurate readings (Using Apple Watch to Measure Heart Rate, Calorimetry, and Activity, 2024). With this technology, Apple integrates software that introduces fitness features which are valuable affordances for setting exercise goals, so that users are able to “close” their activity rings and even create streaks. Users are also able to connect with their friends so that their physical activity and goal achievements are public so that external influences can hold them accountable. Additionally, the Apple Watch uses a Taptic Engine and built-in speakers to deliver notifications which affords an interactive experience for the user to hear and feel alerts (Apple, 2014). This is unique to Apple, setting them apart from other smartwatch vendors that rely solely on sound or vibration.

Psychological Impacts of Apple Watch Use

Wearing an Apple Watch can have lasting effects on a user’s behavior, cognition, and social-emotional well-being. As previously mentioned, its advanced technology, such as health monitoring, cognitive engagement, and emotional connection affords both benefits and challenges with continued use. Numerous studies investigate specifically how the Apple Watch alters a person’s psychology and how the behavioral, cognitive, and social-emotional impacts are interdependent of one another.

Behavioral Impacts

A study conducted by (Zahrt et al., 2023) highlights the ways behavior changes in an Apple Watch user, by highlighting Activity Adequacy Mindsets as a significant driver for influencing dietary choices. Their experiment had participants wear an Apple Watch with a custom step-count app, “AccuSteps.” They then randomly assigned 162 participants into four conditions: “accurate step count feedback,” which is the control; “deflated step count feedback,” which is 40% lower than actual; “inflated step count feedback,” which is 40% higher than actual; and “meta-analysis intervention with accurate feedback,” where the participants received accurate step count with mindset training. Across the five-week process, they collected data on their behavior using self-report measures. The researchers found that accurate step count feedback improved their diet quality, but showed no change in their physical activity levels. Deflated step counts led to negative effects with increased unhealthy eating. Inflated step counts, however, did not significantly change behavioral outcomes. Activity Adequacy Mindsets were linked to dietary choices, suggesting they are a determinant for health outcomes. Despite physical activity was not significantly correlated in this study, the research of Nuss & Li, (2021) found that smartwatch users presented lower sedentary behaviors than users who formly wore a smartwatch. This can be attributed to behavioral nudges and notifications reminding users that it is time to stand or close their rings and achieve fitness goals. A quote from a user demonstrates this: “Yeah, on the fitness app, it’ll tell me you need to get up and move… So, it keeps me notified of what I need to do as far as getting my steps in every hour and throughout the day,” (Asimakopoulos et al., 2024). The nudges from the Apple Watch act as external triggers that align with operant conditioning, providing positive reinforcement for goal-oriented behavior.

Cognitive Impacts

Both studies from Siepmann and Kowalczuk (2021) and Pardamean et al. (2020) emphasize how the Quantified Self impacts a person’s self-perception, satisfaction, and motivation for their daily activities. Self Quantification features of the Apple Watch help users become more aware of how they behave, allowing them to set realistic health and fitness goals provoking them to change and lead a healthier lifestyle. By setting goals, motivation to achieve them increases, aligning with the Self-Determination Theory, and by reaching goals users can build self-efficacy. On the other hand, an over-reliance on device feedback can create feelings of guilt or failure if goals are not met. A former user describes their experience: “It was depressing to see streaks of not making the goals… and I felt even guiltier ignoring it, so I took it off,” (Nuss & Li, 2021).  Another negative concept produced by wearing an Apple Watch is the potential for experiencing cognitive overload. Although some users claim that having alerts and notifications are helpful reminders, excessive notifications could also distract users similar to other device notifications. For instance, when someone is trying to complete a task and they a notification provoking attention to a secondary task, they experience an interruption lag as they engage with the secondary task. When returning to the primary task there is an additional absorption lag as they return to the task they were interrupted (Trafton et al. 2003). This vicious cycle can result in cognitive overload, as fragmented attention impairs users’ productivity in daily tasks.

Social and Emotional Impacts

Several studies mention how the Apple Watch influences users’ social and emotional well-being by fostering connection and improving emotional regulation. Research shows that when people are aware of their physical activity and are engaging in educational videos with reflective exercises, they learn to adopt positive mindsets about their activity (Zahrt et al., 2023). This leads to improved Activity Adequacy Mindsets. Studies from both Zahrt et al., (2023) and Nuss & Li, (2021) show better mental health, well-being, and more positive affective states from regular physical activity. In addition to the exercise and fitness features of the Apple Watch, the sociability features of sharing data or competing in friendly exercise competitions with friends and family can boost a sense of connectedness as well as extrinsic motivation (Asimakopoulos et al., 2024). This acts as positive reinforcement from having shared goals and strengthens bonds, creating a supportive network that encourages continued engagement in healthy behaviors. On the contrary, a negative emotional experience can occur when people believe that their physical activity level is inadequate when they compare themselves to others. This mindset is associated with negative affective states increasing stress and anxiety (Zahrt et al., 2023). Although the sociability features may intend to be a positive concept, it leaves users susceptible to self-comparison.

Conclusion

A review of the literature reveals how the Apple Watch exerts both beneficial and challenging effects on human psychology. The behavioral, cognitive, and social-emotional impacts are deeply intertwined, forming a feedback loop that shapes the user experience. For instance, cognitive impacts feed into social-emotional experiences with the Apple Watch’s quantification of data which enhances self-perception and satisfaction. These emotional responses influence behavior, motivating users to either persist or disengage from their smartwatch. Social-emotional impacts feed into behavior and cognition through activity sharing and fitness competitions. Although these tools foster connection, social comparison from seeing others’ achievements can trigger feelings of inadequacy and diminish motivation. Together, these elements demonstrate a reciprocal relationship, and addressing the interdependent psychological effects indicates the need to design wearable technology that supports users holistically, minimizing psychological risks and maximizing its benefits.
