为了在语篇的层面上从浅层的语词加工和深层的情境加工两个角度考察时间参照加工的特点,采用单因素4水平重复测量实验设计,使用EyelinkⅡ型眼动仪比较了时间参照与时间转换的眼动指标。结果显示,时间词区:远参照与短时转换的眼动指标接近,近参照与长时转换的指标接近;关键事件区:远参照与长时转换的指标接近,近参照与短时转换的指标接近。结果表明时间参照表现出类似时间转换的特点,其特点与能否维系语篇的因果连贯性相关。 相似文献

The Influence of Time Estimation and Time‐Saving Preferences on Learning to Make Temporally Dependent Decisions from Experience

In this paper, we merge research related to experiential learning, temporal perception, and the value of time and money by examining decisions where the timing of action (response) determines the outcome received. We predicted that time‐saving preferences and impatience would decrease maximization (i.e., taking action when it returned the largest reward), and that the constraints of temporal perception would compound their effects. Across three studies, participants undershot on average (i.e., responded earlier than the period of time during which a response would return the maximal reward) showed a preference for shorter‐delay options and often did not find the maximal reward. In addition, participants' reliance on temporal perception increased undershooting, increased preferences for shorter‐delay options, and reduced maximization. Nevertheless, participants who found the maximal reward continued to maximize at a high rate rather than opting for shorter delays and smaller rewards. Thus, while most participants appeared to have a preference for saving time, most behaved as reward maximizers rather than temporal discounters. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

Reminiscence functions over time: consistency of self functions and variation of prosocial functions
The current study examines the temporal stability of the tripartite model of reminiscence functions in which eight separate reminiscence functions map onto three second-order factors which contribute significantly to measurement of an overarching reminiscence latent construct. We collected online responses from 411 adults 50+ years of age. Confirmatory factor analytic models were computed at three points of data collection over 16 months. Invariance analyses were next undertaken to simultaneously compare the measurement properties to assess within-person stability of reminiscence functions over time. The tripartite structure of reminiscence functions was replicated at each point of data collection. As hypothesised, self-positive and self-negative functions are consistent across points of data collection, whereas prosocial functions vary over time. The temporal stability of the self functions may be attributed to enduring characteristics of the individual such as personality traits and life attitudes, as well as their solitary nature. Previous research indicates that consistency of self-positive reminiscence functions has ensuing benefits for physical health and psychological well-being; the opposite is true for self-negative functions. The temporal variation of prosocial functions may be due to the varying availability of others to share memories and their responsiveness to the emotional context. 相似文献

In the context of forensic psychiatry, it is crucial that diagnoses of deviant sexual interests are resistant to manipulation. In a first attempt to promote the development of such tools, the current fMRI study focusses on the examination of hemodynamic responses to preferred, in contrast to non-preferred, sexual stimuli with and without explicit sexual features in 24 healthy heterosexual subjects. The subliminal stimulus presentation of sexual stimuli could be a new approach to reduce vulnerability to manipulation. Meaningful images and scrambled images were applied as masks. Recognition performance was low, but interestingly, sexual preference and explicitness modulated stimulus visibility, suggesting interactions between networks of sexual arousal and consciousness. With scrambled masks, higher activations for sexually preferred images and for explicit images were found in areas associated with sexual arousal (Stoleru, Fonteille, Cornelis, Joyal, & Moulier, 2012). We conclude that masked sexual stimuli can evoke activations in areas associated with supraliminal induced sexual arousal. 相似文献

According to the global neuronal workspace model of consciousness, consciousness results from the global broadcast of information throughout the brain. The global neuronal workspace is mainly constituted by a fronto-parietal network. The anterior insular cortex is part of this global neuronal workspace, but the function of this region has not yet been defined within the global neuronal workspace model of consciousness. In this review, I hypothesize that the anterior insular cortex implements a cross-modal priority map, the function of which is to determine priorities for the processing of information and subsequent entrance in the global neuronal workspace. 相似文献

使用《运动想象问卷−修订版》筛选出的30名被试(男女各半), 采用功能性近红外光谱成像技术(fNIRS)监测被试在执行实际举哑铃(男生, 4磅和8磅; 女生, 2磅和4磅)任务和想象举同等重量哑铃任务时, 其大脑皮层氧合血红蛋白浓度的变化。结果发现:男女被试在运动执行与运动想象任务下都激活了主运动皮层; 且运动执行的大脑激活水平高于运动想象。在执行实际运动任务时, 运动强度显著影响大脑皮层血氧浓度的变化, 表现出左半球偏侧化优势; 在执行想象运动任务时, 运动强度没有影响大脑皮层血氧浓度的变化, 且无偏侧化现象。 相似文献

ABSTRACT— Studying the brains of blind individuals provides a unique opportunity to investigate how the brain changes and adapts in response to afferent (input) and efferent (output) demands. We discuss evidence suggesting that regions of the brain normally associated with the processing of visual information undergo remarkable dynamic change in response to blindness. These neuroplastic changes implicate not only processing carried out by the remaining senses but also higher cognitive functions such as language and memory. A strong emphasis is placed on evidence obtained from advanced neuroimaging techniques that allow researchers to identify areas of human brain activity, as well as from lesion approaches (both reversible and irreversible) to address the functional relevance and role of these activated areas. A possible mechanism and conceptual framework for these physiological and behavioral changes is proposed. 相似文献
