We describe a new method for mapping spatial attention that reveals a pooling of attention in the hemifield opposite a peripheral flash. Our method exploits the fact that a brief full-field blank can interfere with the detection of changes in a scene that occur during the blank. Attending to the location of a change, however, can overcome this change blindness, so that changes are detected. The likelihood of detecting a new element in a scene therefore provides a measure of the occurrence of attention at that element's location. Using this measure, we mapped how attention changes in response to a task-irrelevant peripheral cue. Under conditions of visual fixation, change detection was above chance across the entire visual area tested. In addition, a “hot spot” of attention (corresponding to near-perfect change detection) elongated along the cue-fixation axis, such that performance improved not only at the cued location but also in the opposite hemifield.

Abrupt Change Detection

Abstract. Based on Detrended Fluctuation Analysis (DFA), we propose a new method – Moving Detrended Fluctuation Analysis (MDFA) – to detect abrupt change in dynamic structures. Application of this technique shows that this method may be of use in detecting time-instants of abrupt change in dynamic structures and we even find that the MDFA results almost do not depend on length of subseries, and are less affected by noise.

The Empirical Analysis

AbstractThis article brings together researchers from Stylistics and Psychology to study whether text fragmentation, which appears often to be used by writers as a foregrounding device (Mukařovský 1964), is able to capture the attention of readers of narratives. We examine two types of text fragmentation: sentence fragments and mini-paragraphs. Firstly, we study the stylistic functions of fragmentation, including its cumulative use at plot crucial moments and its use for local rhetorical purposes. We then turn to psychological research on depth of processing (e.g. Sanford and Sturt 2002) and introduce a new method of testing, the text change detection method (Sturt at al. 2004). We report an experiment using this method to examine whether text fragments and very short sentences can increase the amount of detail that readers notice in a text, and then discuss the results in relation to potential applications. The work provides both a case study of the empirical analysis of foregrounding devices, and also, more generally, a case study of inter-disciplinary research across the Humanities and Social Sciences.

The three principal stresses of unit body correspond to the three circles of stress. Each circle of stress corresponds to one of the biggest shear stresses. Each of the biggest shear stresses corresponds to a shear stress’s specific energy. Therefore, specific energy of unit body is solved. It is compared with specific energy of shear stress, staying a dimensional state of stresses with materials flow destruction. And people can get a common formula about specific energy theory of the shape change during the engineering design. The new method’s proving process is very simple, and the nature of failure mechanism is clearer.
