Defines the combined set of features that are sought in a visual search task. Population responses Snapshots of the spiking activity of a collection of individual neurons in response to a single trial in one experimental condition. Trial variability Variability in the responses of an individual neuro...
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 ...
if we can quantify the amount of ~ information for a given number of symbols ~ 3 in the control condition and a given l:; 2 proportion of target symbols in the set ..( condition, then we should predict that if the two information measures are identical, , , , ,1 the search times ...
Participants performed a visual search task with varying parameters while electroencephalography (EEG) was simultaneously recorded (Fig.1). In Experiment 1, the effect of discriminability between target and distractors was tested with three conditions (high, medium, and low discriminability; blocked). ...
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...
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, ...
We are assessing a variety of visual and attentional abilities, including several measures of visual search. For example, in one task we employed a simplified visual search experiment to directly compare novice searchers (Duke University undergraduates) to expert searchers (TSA officers). Participants ...
Overly selective set of measures (KPIs) blindly applied to a process results in distorted effect. People tend to optimize locally by "gaming" the system in order to satisfy particular metrics instead of paying attention to holistic outcome of their actions. Real-world examples: Assert-free tests...
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 ...
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...
