In the Abrupt contrast onset/offset task objects appeared at a constant contrast between foreground and background for four computer-refresh frames (50 ms).
Figure 2 illustrates that the Good MC group demonstrated a lower mean contrast threshold than the Poor MC group on the Abrupt contrast onset/offset task.
However, since pressure exists to make even stationary robots operate in dynamic environments with increasingly more encounters with demands for flexible operations, abrupt changes in tasks, and perturbations, it appears a similar change in approach to robotics as a whole needs to be considered.
In stepping aside, Mr. Lay left to Mr. Skilling -- whose manner was seen by many as far more abrasive and abrupt -- the delicate task of explaining Enron to its critics.
This was achieved by manipulating the degree to which line-drawings of objects appeared suddenly or not by including abrupt and ramped onset tasks, and comparing two subgroups presumed to differ only in their performance on motion coherence ability - a task considered to be representative of dorsal stream functioning.
Finally, we compared the two subgroups of Motion Coherence abilities on the Abrupt and Ramped Object Recognition tasks.
Presence of explicit knowledge (insight) after sleep was determined from NRT task performance by an abrupt reaction time (RT) decrease and a short-cut in sequential responding (Fig. 1A) and was confirmed by answers in the post-experimental questionnaire.
Although both groups only differed in motion coherence performance (a dorsal stream measure), the good motion coherence group showed superior contrast sensitivity for object recognition on the abrupt, but not the ramped presentation tasks.
Besides the fact that this type of phase-locked activity coincided with early ERP components, the phase-locked activity also coincided with an abrupt decline in the onset frequency of task-relevant synchronized intervals (Fig. 12).
Given the nonlinear relationship between Motion Coherence and Abrupt Object recognition, participant thresholds for the Motion Coherence task were ranked, and the top and bottom thirds were categorized as the Good and Poor Motion Coherence (MC) groups, respectively.
