Researchers have ample reasons to take their experimental studies out of the lab and into online wilderness. For some, it is necessity, due an unforeseen laboratory closure or difficulties in recruiting on-site participants. Others want benefit from large diverse population. However, transition in-lab data acquisition not trivial might seem overwhelming at first. To facilitate this transition, we present overview actively maintained solutions for critical components successful acquisition:...

It was shown previously that observers can learn to exploit an uneven spatial distribution of singleton distractors better shield visual search from in the frequent versus rare region (i.e., distractor location probability cueing; Sauter, Liesefeld, Zehetleitner, & Müller, 2018). However, with defined same dimension as target, this comes at cost impaired detection targets region. In 3 experiments, present study investigated learning and unlearning cueing carry-over effects same-...

Video gaming has become massively adopted over the last years and Internet disorder (IGD) been noted as an increasing mental health problem. In this context, earlier studies focused on raw playtime (number of hours). Later also incorporated motives while social contexts were not considered directly. Because inclusion is one most powerful predictors general health, in study, we context which games are played. The sample consisted 13,464 participants from 109 different countries, who played...

Abstract Conducting behavioral experiments online has become more prevalent recently. Still, there is reluctance to embrace the possibilities this technology offer. So far, only simple tasks have been replicated in an setting. In order investigate whether collecting also leads high quality data demanding tasks, we directly compared collected lab with from a dual-task paradigm and psychological refractory period paradigm. Experiment 1, recruited local pools, offline; 2, our pool remote...

Abstract This study explores multi-tasking by examining the effects of transitioning from dual-task to triple-task scenarios. Our research extends beyond conventional paradigms investigate impact performance on two participant groups: those unprepared in single, dual, or triple tasks ( N = 14) and previously prepared single dual 13). The consisted a preparation phase with nine sessions an assessment eight sessions. In phase, both groups performed varying complexity (simple, medium, complex)....

Abstract This study investigated how varying difficulty levels modulate haptic foraging performance and search behavior. Thirty-three blindfolded participants had to locate remove 20 target objects within three conditions – easy feature, conjunction, hard feature defined by target-distractor similarity. Response times target-type switching were measured, errors recorded but remained very low across all conditions. Results revealed that higher task was associated with longer response times....

This perspective reflects on the significant influence that Journal of Experimental Psychology: Human Perception and Performance (JEP) has had my research into involuntary capture attention. From foundational debates automatic versus goal-driven attentional control to incorporating concept selection history, JEP consistently provided key theoretical insights robust methodological frameworks. I describe how specific contributions from journal have shaped approach studying distractor...

An overwhelming majority of studies on visual search and selective attention were conducted using computer screens. There are arguably shortcomings in transferring knowledge from computer-based to real-world behavior as findings based viewing static pictures This does not go well with the dynamic interactive nature vision real world. It is crucial take research world order study everyday processes. The aim present was develop an paradigm that can serve a “bridge” between classical...

Abstract Traditional visual attention research predominantly employs a search paradigm focused on identifying single target within scene. This approach, however, may not fully encapsulate the complexities of natural environmental interactions, which often involve multiple decisions and actions. Addressing this gap, recent advancements have introduced touch-screen-based foraging tasks, where participants are required to identify cancel targets through tactile interaction. Despite its...

In online lectures, showing an on-screen instructor gained popularity amidst the Covid-19 pandemic. However, evidence in favor of this is mixed: they draw attention and may distract from content. contrast, using signaling (e.g., with a digital pointer) provides known benefits for learners. But effects were only researched absence instructor. present explorative study, we investigated on division learners´ attention; specifically, following pointer signal their gaze. The presence led to...

The effective delivery of e-learning depends on the continuous monitoring and management student attention. While instructors in traditional classroom settings can easily assess crowd attention through gaze cues, these cues are largely unavailable online learning environments. To address this challenge highlight significance our study, we collected eye movement data from twenty students developed four visualization methods: (a) a heat map, (b) an ellipse (c) two moving bars, (d) vertical...

Interacting with a group of people requires to direct the attention whole group, thus feedback about crowd's attention. In face-to-face interactions, head and eye movements serve as indicator for crowd However, when interacting online, such indicators are not available. To substitute this information, gaze visualizations were adapted scenario. We developed, implemented, evaluated four types in an online study 72 participants using lecture videos enriched audience's gazes. All reported...

Our eyes convey information about a person. The pupils may provide regarding our emotional states when presented along with different expressions. We examined the effects of pupil size and vergence on inferring other people's characteristics in neutral expression eyes. Pupil sizes were manipulated by overlaying black disks onto original eye images. disk area was then changed to create small, medium, large pupils. Vergence simulated shifting medium-sized nasally one eye. exaggerated for...

Webcam-based eye-tracking promises easy and quick data collection without the need for specific or additional hardware. This makes it especially attractive educational research, in particular modern formats, such as MOOCs. However, order to fulfill its promises, webcam-based eye tracking has overcome several challenges, most importantly, varying spatial temporal resolutions. Another challenge that domain faces especially, is typically individual students are of interest contrast average...

<title>Abstract</title> The watching eyes effect influences people to behave more prosocially or less antisocially. It is currently unknown how the themselves induce this effect. To fill gap, we varied emotional expressions (angry, fear, happy, neutral), age (old, young), and sex (male, female) of investigate which characteristics influence antisocial behavior. Participants rated extent they would utter 36 stereotypical statements about race, gender, religion topics. Each statement was...

Abstract Multitasking research in the laboratory is dominated by extremely simplistic dual-task paradigms. Although dual-tasks allow for some variations, they do not compare well to more complex everyday task settings. This study expands a classical paradigm adding third task. The and triple-task always consisted of same three single tasks. aim was investigate effects combinations single-tasks which manner response times costs increased. Stimulus-response pairings were varied either once...

People can learn to ignore salient distractors that occur frequently at particular locations, making them interfere less with task performance. This effect has been attributed learnt suppression of the likely distractor locations a pre-selective stage attentional-priority computation. However, rather than frequent (vs. rare) being just capture attention, attention may possibly also be disengaged faster from such – post-selective contribution their reduced interference. Eye-movement studies...

Giving effective lectures requires managing all students' attention. In lecture rooms, such crowd attention is typically intuitively assessed by judging gaze cues. However, in online teaching, cues are often missing. a series of studies, we aimed at facilitating teaching visualizing eye movement synchronicity and predicting learning success: (1) We recorded students‘ gazes (fixation positions) on PowerPoint slides visualized the aggregated to lecturers as heat map, an ellipse two moving...

Abstract The watching eyes effect has been shown to influence prosocial and antisocial behaviors. However, the eye characteristics which induce this remain unclear. This study explored how emotional expressions (anger, fear, happy, neutral), age (old, young), sex (male, female) of images affect behavior, measured by stereotype endorsement. Participants rated their endorsement 36 statements about race, gender, religion topics, each paired with an image. Our findings indicated that did not...
