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
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...
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...
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...
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...
16 (2), 253-258 Visual search in a forced-choice paradigm* JOHN E. HOLMGREN University of Maryland, College Park, Maryland 20742 The processing of visual information was investigated in the context of two visual search tasks. The first was a forced-choice task in which one of two ...
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...
Prather and Bacon (1986) showed that children can attend to either the parts or the whole of a spatial pattern, but their performance can be influenced by specific task and stimulus manipulations. Data from a large series of studies using different measures with children ranging in age from 3...
Openness 📖.- A value in [0,1] which measures how far the object has been opened. Position 📍, Rotation 🙃, and bounding box 📦- The 3D position, rotation, and bounding box of each object. Broken- A boolean indicating if the object has been broken (all goal object poses are ...
