图标形象度影响早期识别进程: 来自ERP的证据

人们主观上认为形象图标容易识别,然而以反应时为指标的行为实验发现,随着熟悉度增加,形 象优势逐渐消失。本研究采用事件相关电位(ERPs)技术,记录分析了 17 名熟练用户在识别图标时的识别电 位(RP)。结果显示:图标形象度对 RP 在潜伏期无显著差异,但形象图标反应时比抽象图标短,且形象图标 的RP波幅显著小于抽象图标。这一结果说明识别形象图标在类别分拣进程中处理的特征信息量较抽象图标少。     

A Brief Argument For Consciousness Without Access

This paper proposes a new argument in favour of the claim that phenomenal consciousness overflows – that is, has a far higher capacity than – cognitive access. It shows that opponents of overflow implicate a necessary role for visual imagery in the change detection paradigm. However, empirical evidence suggests that there is no correlation between visual imagery abilities and performance in this paradigm. Since the use of imagery is not implicated in the performance strategy of subjects, we find a new argument for consciousness without access.     

Expressing the Nature and Meaning of DNA: Six Books for Teachers and Students

DNA is an important agent not only in chemistry and biology but also in technology and modern culture. A number of books approach the double helix from different angles. These perspectives include (1) the science of DNA and genetics; (2) genetic engineering; (3) the ethics of manipulating genetic material; and (4) DNA in culture and religion. Various views of DNAprovide insights into human nature beyond its molecular composition.     

时间压力下图标语义距离对雷达界面信息工作记忆的影响

本研究分别在无时间压力和有时间压力的条件下,通过两个实验探究了图标语义距离?目标数量以及目标类型对雷达界面信息工作记忆的影响?结果发现无时间压力下图标语义距离在工作记忆的编码提取上没有差异,而有时间压力下,强语义图标相较于弱语义图标在工作记忆的提取上具有优势;且无论是在无时间压力下还是有时间压力下,工作记忆容量最佳为3个目标项;对敌机的提取时长于友机长于不明飞行物?结果表明仅在有时间压力下强语义图标在信息提取上具有优势,验证了工作记忆容量的限制,为雷达界面的设计提供了参考意见?     

Decay in Visuomotor Representations During Manual Aiming

The time course of the decay of spatial representations used for planning and controlling manual aiming has not been established. The authors' purpose in the present investigation was to generate a psychometric function for memory-guided reaching movements. Eight university-aged students performed a reciprocal tapping task for 10 s. Participants could see the targets for 5 s; then, vision of the targets was occluded. The present findings provide mixed support for 2 prominent theories concerning memory representations. Variability increased concurrently with the removal of vision of the targets, supporting the real-time hypothesis. However, a brief plateau in the curve was apparent for approximately 2 s after vision was removed, consistent with the use of a highly accurate representation for action.     

The incarnated icon of Ṣaydnāyā: light and shade

The shrine of the Virgin Mary in the Syrian town of ?aydnāyā is an important Levantine Christian centre and one of the principal Christian pilgrimage sites in the Middle East, second only to the holy city of Jerusalem during the Middle Ages. This study's intent is to examine in detail, and to provide a key for interpreting, the major incongruity emerging through a comparison of the two main textual traditions regarding the shrine: the Christian-Arabic and the Latin-Western. The dissimilarity is constituted by the significant divergences concerning the representation of the miracle of the incarnation traditionally ascribed to the icon of the Virgin venerated in ?aydnāyā, which is essentially omitted in the Christian-Arabic sources. I argue that a key to the understanding of this reticence can be provided by an analysis of the heretical character ascribed to this particular miracle in Islamic theological thought and of the consequent threat it posed to the survival of the shrine itself. That being the primary focus of the investigation, the article also explores some aspects of the cultural and historical vicissitudes and crises of the cult of the shrine in the West from the fourteenth century onwards which, despite the great number of academic works dedicated to this subject, have remained unclear to this day. More specifically, I argue that apparently aporematic elements on the textual level can be interpreted logically by examining the central role played by the Knights Templar in the cult's material and cultural diffusion and by taking into account the connection of the shrine's decay with the order's downfall. The present analysis focuses almost exclusively on the medieval period as being the most significant for the formation and development of the cult of the shrine.     

形象度对图标内隐记忆和外显记忆的影响

记忆心理学领域大量研究证实了内隐记忆和外显记忆的ERP分离,且内隐记忆相比外显记忆在记忆容量、保持时间及稳定性上均有优势。实验记录了15名被试在内隐记忆任务与外显记忆任务中形象图标和抽象图标的行为及ERP数据。结果表明:内隐记忆中,形象图标的行为和300～500ms顶区差异波的启动量均显著高于抽象图标。外显记忆中,形象图标的外显记忆正确率显著高于抽象图标,而反应时无显著差异; 300～500ms额区的差异波,形象图标显著负向于抽象图标,而500～800ms顶区的晚成分差异波两者无显著差异。研究结果表明,形象图标在浅加工下进行无意识记忆具有明显的优势。形象图标与抽象图标在图形化界面语言的使用中一直存在争论,通过实验在行为指标与脑电生理指标上提供了量化证据。     

Identity motives and cultural priming: Cultural (dis)identification in assimilative and contrastive responses

The present article explores whether effects of cultural primes are influenced by identity motives as well as by construct accessibility. The authors hypothesized that assimilative responses (shifting one’s judgments toward the norm of the primed culture) are driven by identification motives, whereas contrastive responses (shifting away from this norm) are driven by disidentification motives. Evidence for this claim was attained in reanalyzes of past data sets and a new study of Chinese American biculturals, using improved measures of identification and disidentification motives. Consistent with the identity-motive hypotheses, assimilative responses to American-culture primes occurred for high (but not low) identifiers with American culture, and contrastive responses to Chinese-culture primes occurred for high (but not low) disidentifiers with Chinese culture. Results disconfirmed an alternative account predicting that contrast effects hinge on trait self-consciousness. Consistent with an accessibility saturation account, judgment patterns already heightened in accessibility by the task structure were not made more likely by priming.
