ABSTRACTRecent studies using intentional memory tasks showed that images differ consistently in memorability. Here, we used a surprise recognition memory test. We asked how incidental encoding would affect the consistency and ranking of the memorability scores. If memorability is truly an intrinsic property of the image, one should not expect large differences between incidental and intentional conditions. On the other hand, participants might process images differently when not anticipating a memory test, yielding different results. The study list of our incidental memory task was identical to our previous, intentional study. Participants were to watch the images of this list carefully as they appeared on the screen one by one (free viewing); supposedly for a study about eye movements. Afterwards, a surprise recognition memory test was administered. Despite the free viewing instructions during the study phase, the resulting incidental image memorability scores still showed high levels of consistency across participants. In addition, the overlap between the incidental and intentional memorability ranking was large. These results provide further support for the idea of memorability as an intrinsic image property and add to its ecological validity, as people rarely memorise images intentionally. 相似文献

Although appearances may deceive them, agents are capable of achieving their ends; this success is frequently explained by the fact that the agents may, for example, see a stick in water as bent without believing that it is actually bent. Although the notion of ‘seeing as’ is supposed to both bridge the gap between experience and action and explain our reaction to illusions, such accounts break down because of their exclusive focus on visual episodes and their tendency to interpret the metaphysics of agency in a psychologistic fashion. This paper shows that ‘seeing as’ needs to be understood as a species of the genus ‘taking as.’ The genus admits a wider array of expression, in terms of the kinds of attitudes, actions, and epistemological statuses involved. Such an analysis allows us to avoid the problems of ‘seeing as’ accounts and deepens our understanding of the relationship between practical and theoretical reason. 相似文献

采用启动范式, 以汉语听者为被试, 考察了非言语声音是否影响言语声音的知觉。实验1考察了纯音对辅音范畴连续体知觉的影响, 结果发现纯音影响到辅音范畴连续体的知觉, 表现出频谱对比效应。实验2考察了纯音和复合音对元音知觉的影响, 结果发现与元音共振峰频率一致的纯音或复合音加快了元音的识别, 表现出启动效应。两个实验一致发现非言语声音能够影响言语声音的知觉, 表明言语声音知觉也需要一个前言语的频谱特征分析阶段, 这与言语知觉听觉理论的观点一致。 相似文献

研究使用外显面孔再认实验(实验一)和内隐面孔感知实验(实验二)检验自我参照框架是否是自我面孔加工优势出现的决定性因素这一假设。具有不同朝向(左或右)的被试自己面孔和朋友面孔呈现在视野中央, 实验一中, 被试的任务为参照自我框架(观察者角度)或他人框架(被观察的像的角度)判断自我面孔的朝向(忽视朋友面孔), 或者判断朋友面孔的朝向(忽视自我面孔); 实验二中, 被试的任务为参照自我框架或他人框架判断所有面孔的朝向。结果表明:自我参照框架促进自我面孔加工优势的出现, 而他人参照框架消减自我面孔优势, 这种效应稳定地存在于外显和内隐两项任务中。并且, 自我参照框架对自我优势效应的促进作用不依赖于面孔刺激背景。 相似文献

利用反诱导消除McCollough效应 总被引:1,自引:0,他引:1
McCollough效应在完全黑暗和自然视觉条件下的消退过程很缓慢,而利用同频补色条栅来进行反诱导,能在十几分钟内消除显色效应。消除所用时间与反诱导条栅的亮度、颜色和栅条间距(空间频率)有关。进一步说明导致McCollough效应恢复平衡的主要因素跟网膜刺激方式有关。 相似文献

Under a psychophysical trials procedure, pigeons were presented with a red light of one duration followed by a green light of a second duration. Eight geometrically spaced base durations were paired with one of four shorter and four longer durations as the alternate member of a duration pair, with different pairs randomly intermixed. One choice was reinforced if red had lasted longer than green, and a second choice was reinforced if green had lasted longer. Performance was compared when all the base durations and their pair members were included (entire-range condition) or when only the four longest base durations and their comparison durations (restricted-range condition) were used. Discrimination sensitivity decreased for longer duration pairs under both conditions, supporting a memory-based account. Sensitivity was lower under the restricted-range condition. Under both conditions, a bias to report "green as longer" increased as the second green duration increased. Bias changed as a matching function of the green-duration predictiveness of the correct choice. The results are related to a quantitative model of timing and remembering proposed by Staddon. 相似文献

Based on a sample of non-clinical subjects (N=74) the study examines the Defence Mechanism Test (DMT) by focusing on when perceptual distortions, called ‘signs of defence’ in DMT terminology, occur (distribution in exposure duration), which part of the picture is involved (distribution in localisation), and which ‘signs’ go together (using correlation and factor analyses). The results disclosed that the occurrence of perceptual distortions (‘signs of defence’) was related to exposure duration (some ‘defences’ are more frequent at brief exposures, some others at longer exposure durations), and to localisation on the picture. The location of misperceptions to the central person (hero) or the peripheral person (pp) of the picture was the major explanatory principle for the distribution of ‘signs’ on factors. Rather than capturing psychodynamic defence mechanisms, which is the theoretical basis of the test, the analyses imply that the DMT seems to measure misperceptions which are a function of the localisation of persons on the stimulus picture and of exposure durations. 相似文献
