In this paper, 1 describe psychological guidelines for simplifying medical information — methods to aid the perception and recognition of abnormalities in medical test reports. These techniques resemble natural human editing strategies outlined in prospect theory. The methods pre-edit data as humans do but to reduce human effort. I review empirical studies assessing these techniques and discuss needs for further research. 相似文献

An infrared system for the detection of a pigeon''s pecks at alphanumeric characters on a TV screen: the dependency of letter detection on the predictability of one letter by another. 下载免费PDF全文

Three pigeons pecked at letters of the alphabet and at the symbol "?" displayed on a computer-driven cathode ray screen. A 4 by 4 matrix of infrared emitting and detecting diodes and associated circuitry identified the location of a pigeon''s responses to the screen. Responses at the target letter T were probabilistically reinforced with food whenever T appeared in a string of three letters in the middle of the screen. Responses at the symbol "?" appearing below this string were probabilistically reinforced whenever T did not appear. The letter F anywhere in the three-character string either strongly predicted the occurrence of the target letter T, in two conditions, or predicted its nonoccurrence, in a third. This manipulation of the frequency with which the familiar letter F predicted T was shown to change the function relating probability of a correct peck at the symbol "?" to the number of Fs in the string. This effect may be interpreted as an instance of the phenomenon where an organism''s acquired knowledge changes what it sees. 相似文献

Assertive behaviours like showing-off have an important role for a child in getting attention from other children in a class without being aggressive. This study presented the showing-off behaviour in an English nursery school, and later it was discussed in comparison with that in the German kindergartens reported by Hold-Cavell. As a result, the English children performed showing-off behaviours at only one-half the frequency of German children. No sex difference was seen in either showing-off or physical aggression in the nursery class. The frequency of showing-off did not correlate with that of physical aggression; this result is discussed in terms of Hinde's motivational postulate. Showing-off behaviour is deserving of the further studies cross-culturally and onto-genetically. 相似文献

Driver distraction is a major cause of road crashes and has a great influence on road safety. In vehicles, one of the common distracting sources is navigation systems (NSs). The navigation system (NS) can distract the driver due to following directions and reading the provided information through its display. These tasks take the driver’s attention from the primary task of driving and may cause poor driving performance, increasing the risk of crashes. In this paper, the effect of the environment (i.e., urban areas and rural areas), the navigation system display (NSD) size, environmental illumination, and gender on young drivers between the ages of 18 and 29 years mental workload was investigated using a simulated driving experiment. To evaluate each driving condition, the NASA-TLX (NASA Task Load Index) workload assessment tool, and a distraction evaluation element, were introduced and used to assess the overall workload, the workload subscales and the distraction by the NSD. The assessment showed a higher perceived overall workload for urban areas and night driving as compared to a rural areas and daytime driving. Moreover, the results showed a greater perceived distraction by the NSD in urban areas compared to driving in rural areas. The subjects also felt distracted when using the small NS compared to using the large NS. The study concluded that urban areas driving, and night driving creates higher perceived workload than rural areas and daytime driving. Furthermore, small NSD leads to more perceived distraction than large NSD while driving. The NSD designers may utilize this research findings to optimize NSD designs to improve driving safety, performance and comfort. Moreover, this study contributes to our understanding of the effect of the NSD size on driving workload and distraction. 相似文献

The paper provides a uniform Gentzen-style proof-theoretic framework for various subsystems of classical predicate logic. In particular, predicate logics obtained by adopting van Behthem's modal perspective on first-order logic are considered. The Gentzen systems for these logics augment Belnap's display logic by introduction rules for the existential and the universal quantifier. These rules for x and x are analogous to the display introduction rules for the modal operators and and do not themselves allow the Barcan formula or its converse to be derived. En route from the minimal modal predicate logic to full first-order logic, axiomatic extensions are captured by purely structural sequent rules. 相似文献

Understanding positive emotions' shared and differentiating features can yield valuable insight into the structure of positive emotion space and identify emotion states, or aspects of emotion states, that are most relevant for particular psychological processes and outcomes. We report two studies that examined core relational themes (Study 1) and expressive displays (Study 2) for eight positive emotion constructs—amusement, awe, contentment, gratitude, interest, joy, love, and pride. Across studies, all eight emotions shared one quality: high positive valence. Distinctive core relational theme and expressive display patterns were found for four emotions—amusement, awe, interest, and pride. Gratitude was associated with a distinct core relational theme but not an expressive display. Joy and love were each associated with a distinct expressive display but their core relational themes also characterised pride and gratitude, respectively. Contentment was associated with a distinct expressive display but not a core relational theme. The implications of this work for the study of positive emotion are discussed. 相似文献
