Active vs passive media multitasking and memory for lecture materials.

Access to digital technology in the 21st century has led to the emergence of media multitasking (MMT), which involves attempting to engage with multiple streams of media at the same time. This behaviour, which is frequently considered to be a form of inattention, has become increasingly prevalent in educational settings, such as undergraduate lectures. The aim of the present study was to examine volitional media-multitasking (MMT) during an asynchronous online lecture by giving participants the opportunity to engage with a secondary, non-required media stream (i.e., the game of snake). Participants (n = 222) were randomly assigned to either an Active condition, in which they could play the snake game using the arrow keys; or a Passive condition, in which they could watch the snake game, but could not play it. In both conditions, participants could toggle the snake game on and off, using a keypress. MMT was indexed behaviourally by measuring the percentage of time participants had the secondary stream toggled on (i.e., snake time percentage), a method pioneered by Ralph et al. (2020), and subjectively by asking participants to what extent they engaged with other media while the lecture was playing. Following the lecture, participants completed a multiple-choice quiz and self-reported their level of MMT. Our behavioural measure (i.e., snake time percentage) indicated that participants spent significantly more time MMT in the Active condition than the Passive condition. However, there were no significant differences in self-reported MMT or quiz performance across conditions. Furthermore, correlations between both measures of MMT and quiz performance were non-significant. Thus, the present study found no performance decrement as a result of, or in association with, increased volitional MMT.

Examining the relation between oral contraceptive use and attentional engagement in everyday life.

Oral contraceptives (OCs) used by women worldwide include artificial estradiol and progesterone, which can attach to receptors in the brain and potentially influence cognition. In the present studies, we examined the relation between OC use and self-reported everyday attention. We collected trait-level measures of mind wandering, attention-related errors, and attention lapses in undergraduate women using OCs (Study 1: OC group N = 471, Study 2: OC group N = 246) and naturally cycling women not using any form of hormonal contraceptives (Study 1: Non-OC group N = 1,330, Study 2: Non-OC group N = 929). In Study 1, we found that women using OCs reported significantly less spontaneous and deliberate mind wandering than naturally cycling women and no differences between groups on attention-related errors and attention lapses. In Study 2, our findings indicated no significant differences between groups on any of our attention measures. Regression analyses controlling for depression symptoms and semester of data collection found that OC use did predict unique additional variance on some attention measures, but these effects were small and unreliable across the two studies. Taken together, our data suggests there is little evidence that OC use is related to differences in attentional engagement in everyday life.

Sustained attention and the experience of flow.

The state of flow-often referred to as being "in the zone"-is characterized by the experience of deep, effortless concentration on the activity one is engaged in. While much of the flow literature seems to imply a tight link between flow and attention processes, relatively little work has assessed this question empirically. In the present study, we explored how the experience of flow relates to behavioural performance on the Sustained Attention to Response Task (SART). Flow was indexed at the state level using thought-probes and at the trait level via questionnaires. The main finding was that those who experienced more state-level flow during the SART made fewer commission errors during the task, indicating that flow is linked to better sustained attention. Interestingly, the correlation between flow and sustained attention performance was found to increase in the second half of the task. While trait flow was not related to SART performance, it was found to be predictive of state flow during the task, such that those who tended to experience higher levels of flow in their everyday lives also experienced more flow during the experiment.

Loading loading The influence of download time on information search.

When browsing online, there is considerable variation in the amount of time that one has to wait for content to appear once the link to that content has been activated (i.e., clicked). In two experiments we examined how 'download time'-a potential barrier to information access-influences search behaviour. In both experiments, participants completed a video-watching task in which they were presented with a screen containing six clickable icons, each of which represented a unique video. When participants clicked an icon, a video would begin to load and then play. The participants' task was to gain as much information from the videos as possible for a later memory test. Critically, however, the 'download time' (i.e., the time between the click on the icon and the video beginning to play) of the available videos in a given search session varied. In Experiment 1, these download times were 0 (instant), 2, or 30 seconds, and in Experiment 2, they were 5, 15, or 30 seconds. In general, we found that participants terminated and avoided videos with longer download times than videos with shorter download times. Interestingly, this effect was attenuated when the experienced download times were more similar to each other (Experiment 2) than when they were more different from each other (Experiment 1).

Deep, effortless concentration: re-examining the flow concept and exploring relations with inattention, absorption, and personality.

Conceptualizing the construct of flow in terms of 'deep and effortless concentration', we developed two measurement scales designed to index individual differences in flow during 'internal' tasks, such as thinking (deep effortless concentration: internal-DECI) and during 'external' tasks, such as while playing a sport (deep effortless concentration: external-DECE). These scales were highly correlated, indicating that individuals prone to experiencing flow in external contexts are also prone to experience flow in internal contexts. Nonetheless, a measurement model construing internal and external flow as related, but separate, constructs was found to fit the data significantly better than a model where they were construed as a single construct. We then explored associations between flow and various forms of everyday inattention. In addition, we explored the relation between flow and the Tellegen Absorption Scale (TAS), an index of absorption, as well as the Big Five personality traits. Amongst other things, we found that flow was negatively related to inattention, indicating that people who experience flow more frequently may experience relatively less inattention in everyday contexts.

Boredom: Under-aroused and restless.

Boredom is a common experience associated with a range of negative outcomes. Debate remains as to whether boredom should be considered a high or low arousal state. We employed passages of text to induce either boredom or interest and probed self-reported levels of boredom, arousal, and restlessness. Results replicated known associations between mind-wandering and state boredom (i.e., mind-wandering was highest for the boredom mood induction). Reports of sleepiness (a proxy for arousal level) were highest for the boring induction. While restlessness was not different for the boring and interesting inductions when they were performed first, restlessness was significantly higher for the boredom induction when it was experienced last. We discuss these results within the context of the debate regarding boredom and arousal.

Advantages of sentence-level fMRI language tasks in presurgical language mapping for temporal lobe epilepsy.

fMRI language mapping has become increasingly utilized for determining language dominance before surgical intervention for temporal lobe epilepsy (TLE). This study aimed to examine the differences between two classes of fMRI word generation tasks used in our clinic: tasks using a single word cue, referred to as simple generative tasks (SGTs), and tasks also involving sentence-level processing, referred to as sentence-level language tasks (SLTs). Specifically, we aimed to investigate the extent and laterality of activation and frontal-temporal connectivity during these language tasks and their relationship to clinical language measures. Thirty-one patients with TLE (18 patients with left TLE and 13 patients with right TLE) performed four language tasks during an fMRI scan, two SGTs and two SLTs. We found significantly greater activity for SLTs over SGTs in bilateral inferior frontal and middle temporal gyri and the left temporal pole. Sentence-level language tasks also showed greater lateralization compared with SGTs. Finally, we found that while activation extent did not correlate with clinical language tests, the degree of left frontal-temporal connectivity was significantly correlated with naming and semantic fluency performance. These correlations also were more robust for SLTs than for SGTs. Taken together, these results provide a compelling argument for including some form of SLTs in fMRI language lateralization protocols for TLE as they allow for better characterization of language networks, particularly in the temporal lobes which are at risk in surgery.
