Making sense of multitasking: The role of Facebook

Media multitasking and Facebook use are commonplace among college and university-aged students. While the two are often linked and each has been independently associated with reductions in academic performance, their relationship to each other is not particularly well understood.This relationship was examined by analysing comprehensive time-based logs of students' computer-based tasks, including Facebook, during unsupervised, self-directed learning sessions. A total of 3372 sessions contributed by 1249 students were analysed. Multitasking was extremely common – around 99% of sessions involved some multitasking (at least three instances of a particular task within a 20 min period). Facebook was the second most common task overall (University was first), accounting for 9.2% of all task instances and being present in 44% of sessions. Sessions containing Facebook typically contained more, shorter duration tasks and were significantly more likely to include multitasking behaviour. The introduction of Facebook within a session was associated with an increase in multitasking and a reduction in focused (no more than two tasks in a 20 min period) behaviour. Facebook users (students who contributed at least five sessions and used Facebook in at least one of these sessions) were also more likely to multitask and less likely to engage in focused behaviour. These results confirm that Facebook use is a key contributor to students' task switching and multitasking behaviours.     

The Effects of Hover Interface on Users’ Behavioral Multitasking Intention

As the number of features with smartphones is increasing, user interfaces have been advanced considerably with innovative ways for providing useful, multitasking interfaces. In particular, the z-axis of the user interface has been considered to help multitaskers control their smartphone more easily. However, relatively little research has been conducted on the significance of the z-axis on task switching. The main research goal of this study is to explain how a z-axis can affect the experience of multitasking on a mobile device. In particular, the authors focused on a hover interface because of its high functional relevance to multitasking as a form of task switching. Theoretically, the authors provide a conceptual model based on the concept of spatial presence. Systemically, they suggest the important system factors for implementing z-axis interface technology: controllability and naturalness. With regards to users, the authors assume that if the experience with the z-axis interface is increased, users’ intention to multitask is also increased, even when the task complexity is high. The influence of controllability on perceived spatial presence by the hover interface was negatively validated, and the influence of naturalness was positively validated. In addition, the influence of perceived spatial presence on users’ behavioral multitasking intention was positively validated. Finally, the influence from perceived spatial presence to users’ behavioral multitasking intention in the high level of task complexity was significantly stronger than in the low level. Implications and limitations of the study results are discussed in the final section of the article.     

Making sense of multitasking: Key behaviours

Traditionally viewed as a positive characteristic, there is mounting evidence that multitasking using digital devices can have a range of negative impacts on task performance and learning. While the cognitive processes that cause these impacts are starting to be understood and the evidence that they occur in real learning contexts is mounting, the mechanics and extent of students' task switching and multitasking during learning activities is neither well documented or understood. This study seeks to redress this gap by defining and describing key task switching and multitasking behaviours adopted by students. It employs computer-based task switching and self-directed learning as the technology and learning frameworks within which these behaviours are explored.A custom monitoring system was used to capture and analyse 3372 computer session logs of students undertaking self-directed study within an open-access computer laboratory. Each session was broken down into a sequence of tasks within a series of time segments. Segments and sessions were then analysed and classified as conforming to one of three core behaviours – little or no task switching (focused), task switching without multitasking (sequential) and multitasking. Multitasking was much more common than focused or sequential behaviours. Multitasking was present in more than 70%, was most frequent in over 50% and occurred exclusively in around 35% of all sessions. By comparison, less than 10% of sessions were exclusively focused and only 7% were exclusively sequential. Once initiated, focused and multitasking behaviours appear to be quite stable. Students were much more likely to continue with them than to switch to an alternate behaviour. Sequential behaviour is far less stable and appears to represent a transitional state between multitasking and focused behaviours.The importance of personal, social and learning contexts in setting and influencing multitasking behaviours are discussed, as are some of the potential effects of these behaviours on learning practises and outcomes.     

Perceived academic effects of instant messaging use

College students use information and communication technologies at much higher levels and in different ways than prior generations. They are also more likely to multitask while using information and communication technologies. However, few studies have examined the impacts of multitasking on educational outcomes among students. This study fills a gap in this area by utilizing a large-sample web-based survey of college student technology usage to examine how instant messaging and multitasking affect perceived educational outcomes. Since multitasking can impede the learning process through a form of information overload, we explore possible predictors of academic impairment due to multitasking. Results of this study suggest that college students use instant messaging at high levels, they multitask while using instant messaging, and over half report that instant messaging has had a detrimental effect on their schoolwork. Higher levels of instant messaging and specific types of multitasking activities are associated with students reporting not getting schoolwork done due to instant messaging. We discuss implications of these findings for researchers studying the social impacts of technology and those in higher education administration.     

In-class multitasking and academic performance

The omnipresence of student-owned information and communication technologies (ICTs) in today’s college classrooms presents educational opportunities but can also create learning problems. Specifically, multitasking with these technologies can interfere with the learning process. Indeed, research in cognitive science shows that there are clear performance decrements when trying to attend to two tasks at the same time. This study examines the frequency with which students multitask during class using a large sample (N = 1,839) and examines the relationship between multitasking and academic performance as measured by actual overall semester grade point average (GPA). Students reported frequently text messaging during class but reported multitasking with other ICTs to a lesser extent. Furthermore, only social technologies (Facebook and text messaging) were negatively related to GPA.     

Juggling on a high wire: Multitasking effects on performance

In this study, we develop a theoretical model that predicts an inverted-U relationship between multitasking and performance. The model is tested with a controlled experiment using a custom-developed application. Participants were randomly assigned to either a control condition, where they had to perform tasks in sequence, or an experimental condition, where they could discretionarily switch tasks by clicking on tabs. Our results show an inverted-U pattern for performance efficiency (productivity) and a decreasing line for performance effectiveness (accuracy). The results of this study indicate that the nature of the relation between multitasking and performance depends upon the metric used. If performance is measured with productivity, different multitasking levels are associated with an inverted-U curve where medium multitaskers perform significantly better than both high and low multitaskers. However, if performance is measured with accuracy of results, the relation is a downward slopping line, in which increased levels of multitasking lead to a significant loss in accuracy. Metaphorically speaking, juggling multiple tasks is much more difficult while balancing on a high wire, where performance mishaps can have serious consequences.     

If I choose when to switch: Heavy multitaskers remember online content better than light multitaskers when they have the freedom to multitask

The present study explored the effects of switching between reading an online article and checking Facebook on recognition memory, moderated by polychronicity, or preference for multitasking. The results of the study indicated that participants recognized online information less efficiently when they were required to check Facebook (forced multitasking) and when they could choose to check Facebook if and when they wanted (voluntary multitasking) compared with the control, non-multitasking, condition. I.e., the opportunity to multitask interfered with the efficiency of online information processing as much as actual multitasking. Polychronicity was a significant moderator of the multitasking effects. Low polychronics were negatively affected by multitasking to a greater extent than high polychronics. Their article recognition levels were lower than those of high polychronics. Two recognition measures derived from the signal detection theory: recognition sensitivity and criterion bias, were used. The study indicated that forced and voluntary multitasking affected high and low polychronics differently. Low polychronics showed greater cognitive effort than high polychronics when they engaged in voluntary media multitasking, while the amount of cognitive resources allocated to processing increased in high polychronics in the non-multitasking (control) condition. When high polychronics did not have control over switching to Facebook (forced multitasking), their recognition of the online article content decreased. Theoretical, methodological, and managerial implications of the study are discussed.     

Multitasking across generations: Multitasking choices and difficulty ratings in three generations of Americans

This study investigated whether changes in the technological/social environment in the United States over time have resulted in concomitant changes in the multitasking skills of younger generations. One thousand, three hundred and nineteen Americans from three generations were queried to determine their at-home multitasking behaviors. An anonymous online questionnaire asked respondents to indicate which everyday and technology-based tasks they choose to combine for multitasking and to indicate how difficult it is to multitask when combining the tasks. Combining tasks occurred frequently, especially while listening to music or eating. Members of the “Net Generation” reported more multitasking than members of “Generation X,” who reported more multitasking than members of the “Baby Boomer” generation. The choices of which tasks to combine for multitasking were highly correlated across generations, as were difficulty ratings of specific multitasking combinations. The results are consistent with a greater amount of general multitasking resources in younger generations, but similar mental limitations in the types of tasks that can be multitasked.     

Media multitasking and psychological wellbeing in Chinese adolescents: Time management as a moderator

The present study examined the relationships among media multitasking, time management, and psychological wellbeing in Chinese adolescents. A total of 320 adolescents aged 11 to 18 years old were recruited and asked to complete the Media Use Questionnaire, Chinese Adolescent Mental Health Inventory, and Adolescent Time Management Disposition scale. A structural equation model was used to assess possible relationships among media multitasking, time management, and psychological wellbeing. The results showed that the media multitasking index of the sample was 2.5, indicating that adolescents also had access to other 2.5 media tasks when performing the primary media task. Media multitasking was significantly negatively correlated with psychological wellbeing. Time management disposition was negatively correlated with Media multitasking and positively correlated with psychological wellbeing. Our findings indicate that time management disposition can moderate the relationship between Media multitasking and psychological wellbeing. The theoretical and practical implications of adolescent media use are discussed.     

No A 4 U: The relationship between multitasking and academic performance

The proliferation and ease of access to information and communication technologies (ICTs) such as Facebook, text messaging, and instant messaging has resulted in ICT users being presented with more real-time streaming data than ever before. Unfortunately, this has also resulted in individuals increasingly engaging in multitasking as an information management strategy. The purpose of this study was to examine how college students multitask with ICTs and to determine the impacts of this multitasking on their college grade point average (GPA). Using web survey data from a large sample of college students at one university (N = 1839), we found that students reported spending a large amount of time using ICTs on a daily basis. Students reported frequently searching for content not related to courses, using Facebook, emailing, talking on their cell phones, and texting while doing schoolwork. Hierarchical (blocked) linear regression analyses revealed that using Facebook and texting while doing schoolwork were negatively associated with overall college GPA. Engaging in Facebook use or texting while trying to complete schoolwork may tax students' capacity for cognitive processing and preclude deeper learning. Our research indicates that the type and purpose of ICT use matters in terms of the educational impacts of multitasking.     

Laptop multitasking hinders classroom learning for both users and nearby peers

Laptops are commonplace in university classrooms. In light of cognitive psychology theory on costs associated with multitasking, we examined the effects of in-class laptop use on student learning in a simulated classroom. We found that participants who multitasked on a laptop during a lecture scored lower on a test compared to those who did not multitask, and participants who were in direct view of a multitasking peer scored lower on a test compared to those who were not. The results demonstrate that multitasking on a laptop poses a significant distraction to both users and fellow students and can be detrimental to comprehension of lecture content.     

Media multitasking predicts video-recorded lecture learning performance through mind wandering tendencies

Media multitasking behaviors are on the rise globally. This phenomenon extends to academic settings, and has implications for education that is predicated on computer-assisted technology, which may be a source of distractibility for, especially, heavy media multitaskers. We hypothesized that habitual media multitasking correlates negatively with video-recorded lecture learning performance, with mind wandering mediating this association. Eighty-one participants from the National University of Singapore first completed a media multitasking survey (Loh & Kanai, 2014; Ophir et al., 2009). They then studied Coursera video-recorded lectures, during which their mind wandering tendencies were assessed using direct probes. Finally, participants attempted a test relating to what they have studied. Four regression models were built to analyse the data, and revealed evidence that supported the present hypothesis, even after we controlled for phenomenological variables relating to learning (i.e., anxiety, mental fatigue, and prior subject knowledge). Implications and future directions are discussed.     

An exploration of social networking site use,multitasking, and academic performance among United States and European university students

Studies have shown that multitasking with technology, specifically using Social Networking Sites (SNSs), decreases both efficiency and productivity in an academic setting. This study investigates multitasking’s impact on the relationship between SNS use and Grade Point Average (GPA) in United States (US; n = 451) and European (n = 406) university students using quantitative and qualitative data analysis. Moderated Multiple Regression analysis results showed that the negative relationship between SNS use and GPA was moderated by multitasking only in the US sample. This may be due to European students being less prone to “disruptive” multitasking. The results provide valuable cautionary information about the impact of multitasking and using SNSs in a learning environment on university students’ GPAs.     

Attention,polychronicity, and expertise in prospective memory performance: Programmers' vulnerability to habit intrusion error in multitasking

The paper examines prospective memory (ProM) in programmer multitasking and reports administration of a naturalistic atypical action. The study emphasizes on how attention, time orientation, and expertise affect ProM performance in multitasking among a group of computer science and engineering students (N=108). The results suggest that attention play a crucial role in multitasking and ProM performance with respect to whether or not a word display requires more attention to be devoted in monitoring and identifying it for an appropriate action. Polychrons exhibit lesser degree of ProM performance failure than monochrons whereas expertise does not have an effect. Finally, results show that out of overall ProM performance failure, habit intrusion errors comprise of 16.22% occurring 1.75 times in every 10 valid click responses of ProM task. Moreover, experts demonstrate a superior performance over novices in programming.     

Exploring relationships between students’ interaction and learning with a haptic virtual biomolecular model

This study explores tertiary students’ interaction with a haptic virtual model representing the specific binding of two biomolecules, a core concept in molecular life science education. Twenty students assigned to a haptics (experimental) or no-haptics (control) condition performed a “docking” task where users sought the most favourable position between a ligand and protein molecule, while students’ interactions with the model were logged. Improvement in students’ understanding of biomolecular binding was previously measured by comparing written responses to a target conceptual question before and after interaction with the model. A log-profiling tool visualized students’ movement of the ligand molecule during the docking task. Multivariate parallel coordinate analyses explored any relationships in the entire student data set. The haptics group produced a tighter constellation of collected final docked ligand positions in comparison with no-haptics students, coupled to docking profiles that depicted a more fine-tuned ligand traversal. Students in the no-haptics condition employed double the amount of interactive behaviours concerned with switching between different visual chemical representations offered by the model. In the no-haptics group, this visually intense processing was synonymous with erroneously ‘fitting’ the ligand closer distances to the protein surface. Students who showed higher learning gains tended to engage fewer visual representational switches, and were from the haptics group, while students with a higher spatial ability also engaged fewer visual representational switches, irrespective of assigned condition. From an information-processing standpoint, visual and haptic coordination may offload the visual pathway by placing less strain on visual working memory. From an embodied cognition perspective, visual and tactile sensorimotor interactions in the macroworld may provide access to constructing knowledge about submicroscopic phenomena. The results have cognitive and practical implications for the use of multimodal virtual reality technologies in educational contexts.     

Gender and cultural differences in Internet use: A study of China and the UK

This study investigates differences in use of, and attitudes toward the Internet and computers generally for Chinese and British students, and gender differences in this cross-cultural context. Two hundred and twenty Chinese and 245 British students’ responses to a self-report survey questionnaire are discussed. Significant differences were found in Internet experience, attitudes, usage, and self-confidence between Chinese and British students. British students were more likely to use computers for study purposes than Chinese students, but Chinese students were more self-confident about their advanced computer skills. Significant gender differences were also found in both national groups. Men in both countries were more likely than women to use email or ‘chat’ rooms. Men played more computer games than women; Chinese men being the most active games players. Men in both countries were more self-confident about their computer skills than women, and were more likely to express the opinion that using computers was a male activity and skill than were women. Gender differences were higher in the British group than the Chinese group. The present study illustrates the continued significance of gender in students’ attitudes towards, and use of computers, within different cultural contexts.     

Can students really multitask? An experimental study of instant messaging while reading

Students often “multitask” with electronic media while doing schoolwork. We examined the effects of one form of media often used in such multitasking, instant messaging (IM). We predicted that students who engaged in IMing while reading a typical academic psychology passage online would take longer to read the passage and would perform more poorly on a test of comprehension of the passage. Participants were randomly assigned to one of three conditions (IM before reading, IM during reading, or no IM). We found that students took significantly longer to read the passage when they IMed during reading (not including time taken to IM) than in other conditions. However, test performance did not differ by condition. Students who are managing busy lives may think they are accomplishing more by multitasking, but our findings suggest they will actually need more time to achieve the same level of performance on an academic task.     

What else do college students “do” while studying? An investigation of multitasking

We investigated the frequency and duration of distractions and media multitasking among college students engaged in a 3-h solitary study/homework session. Participant distractions were assessed with three different kinds of apparatus with increasing levels of potential intrusiveness: remote surveillance cameras, a head-mounted point-of-view video camera, and a mobile eyetracker. No evidence was obtained to indicate that method of assessment impacted multitasking behaviors. On average, students spent 73 min of the session listening to music while studying. In addition, students engaged with an average of 35 distractions of 6 s or longer over the course of 3 h, with an aggregated mean duration of 25 min. Higher homework task motivation and self-efficacy to concentrate on homework were associated with less frequent and shorter duration multitasking behaviors, while greater negative affect was linked to longer duration multitasking behaviors during the session. We discuss the implications of these data for assessment and for understanding the nature of distractions and media multitasking during solitary studying.

Media multitasking during political news consumption: A relationship with factual and subjective political knowledge

Growth of digital, social, and mobile media has enabled engagement with multiple media activities during news consumption in a more efficient and synchronous fashion than before. This study investigates whether media multitasking activities while consuming political news affects individuals' levels of subjective and factual political knowledge. Results from a Web survey of online panel members show that on the whole, pairwise and bundled forms of media multitasking are negatively related to factual political knowledge. Also, those who engage in media multitasking are more likely to report that they are politically knowledgeable but they do not know about politics as much as they think they do. Implications are discussed for media multitasking and an informed citizenry.
