Using a basic visual search task, we studied the effects of increased task difficulty on subject performance and their corresponding eye measures. Results show a decrease in performance as the number of objects on the screen increase. What results could be expected if differences in individual ...
For the tablet task, we only recorded hit rates, which were analysed with a 3 × 3 repeated measures permutation ANOVA with within factors Modality (visual, haptic, multisensory) and Slider (vertical, horizontal, circular). The Greenhouse–Geisser correction for non-sphericity was used when...
As a dependent variable, 2 measures of search performance are calculated: search time and search efficiency. Search time is measured by overall reaction time (RT), whereas search efficiency is calculated as processing time per search item. Search efficiency is derived from the slope of RTs as a...
3 Results The accuracy of the visual search task and the memory test were 99.55% and 92.95% respectively. A repeated measures ANOVA with experiment type and cue type as within factors revealed that, memory accuracy was higher in the working memory condition (94.14%) than in the mental imagery...
or because attention is divided among all stimuli and thus less resources are attributed to each stimulus (here, we do not aim to disentangle these two options). It follows that given a fixed search duration, the more complex the search task, the higher the frequency of the neural oscillation...
and the intuitiveness of that device are. Moreover, efficiency measures correspond to reaction times in the visual search paradigm, as they are also a temporal measure per correct response. Hence, reaction time measures are comparable to “total task time”—or “time on task”—measures that...
Finding an unfamiliar person in a crowd of others is an integral task for police officers, CCTV-operators, and security staff who may be looking for a suspect or missing person; however, research suggests that it is difficult and accuracy in such tasks is low. In two real-world visual-sea...

It lets users anticipate anomalous conditions and apply appropriate mitigative measures, without going through the pain of trial and error. In the .NET Framework, exception documentation is also the standard means of conveying acceptable values for method arguments. To encourage documenting exceptions, ...
one is implicit, driving contextual cueing in the visual-search task; and the other is explicit, facilitating conscious retrieval of context cues in the explicit-memory task. Accordingly, there should be no systematic correlation between measures of contextual facilitation obtained in the search and ...
