Representationalism and the perspectival character of perceptual experience

Perceptual experiences inform us about objective properties of things in our environment. But they also have perspectival character in the sense that they differ phenomenally when objects are viewed from different points of view. Contemporary representationalists hold, at a minimum, that phenomenal character supervenes on representational content. Thus, in order to account for perspectival character, they need to indentify a type of representational content that changes in appropriate ways with the perceiver’s point of view. Many representationlists, including Shoemaker and Lycan, argue that such contents are best construed in terms of mind-dependent properties. Other representationalists, including Tye and Dretske, hold that these contents involve only mind-independent properties. Susanna Schellenberg has recently developed an account of perceptual experience that would serve these latter representationalists extremely well. She suggests that we can do justice to the perspectival character of perceptual experience by appeal to representations of a certain type of relational properties, so-called ‘situation-dependent properties.’ In this paper, I critically engage with Schellenberg’s proposal in order to show how mind-independent representationalists can explain perspectival character. I argue that appeal to situation-dependent properties is problematic. I then show that mind-independent representationalists can account for perspectical character by means of scenario contents in Christopher Peacocke’s sense.     

The effect of study time distribution on learning and retention: a Goldilocks principle for presentation rate

In 2 experiments, we investigated the effect of presentation rate on both immediate (5 min) and delayed (2 days) cued recall of paired associates. Word pairs were presented for a total of 16 s per pair, with presentation duration of individual presentations varying from 1 to 16 s. In Experiment 1, participants studied word pairs with presentation rates of 16 × 1 s, 8 × 2 s, 4 × 4 s, 2 × 8 s, or 1 × 16 s. A nonmonotonic relationship was found between presentation rate and cued recall performance. Both short (e.g., 1 s) and long (e.g., 16 s) presentation durations resulted in poor immediate and delayed recall, compared with intermediate presentation durations. In Experiment 2, we replicated these general findings. Moreover, we showed that the 4 s condition resulted in less proportional forgetting than the 1 s and the 16 s conditions.

Decomposing the interaction between retention interval and study/test practice: the role of retrievability

Even without feedback, test practice enhances delayed performance compared to study practice, but the size of the effect is variable across studies. We investigated the benefit of testing, separating initially retrievable items from initially nonretrievable items. In two experiments, an initial test determined item retrievability. Retrievable or nonretrievable items were subsequently presented for repeated study or test practice. Collapsing across items, in Experiment 1, we obtained the typical cross-over interaction between retention interval and practice type. For retrievable items, however, the cross-over interaction was quantitatively different, with a small study benefit for an immediate test and a larger testing benefit after a delay. For nonretrievable items, there was a large study benefit for an immediate test, but one week later there was no difference between the study and test practice conditions. In Experiment 2, initially nonretrievable items were given additional study followed by either an immediate test or even more additional study, and one week later performance did not differ between the two conditions. These results indicate that the effect size of study/test practice is due to the relative contribution of retrievable and nonretrievable items.     

自闭症儿童的中心信息整合及其与心理理论的关系

研究用积木测验和镶嵌图形测验测量中心信息整合,用5个信念任务测量心理理论能力,比较了12名自闭症儿童和同等言语能力的28名正常儿童的表现,并分析了心理理论和中心信息整合的相关。结果表明:(1)中心信息整合的测量指标积木测验和镶嵌图形测验成绩保持中高度相关;(2)自闭症儿童中心信息整合显著弱于正常儿童;(3)心理理论和中心信息整合成绩相互独立。     

繁殖笼内川金丝猴社群结构的研究

记录了繁殖笼内川金猴(Rhinopithecus roxellanae)成员之间发生的攻击和屈服行为的指向和次数,采用计算优势指数的方法,对数据进行统计和分析。通过优势指数的排列,以及与之有关事件的分析,结果表明繁殖笼内川金丝猴成员之间存在优势等级关系,但不是简单的线性排列;成员之间存在着有弹性的,有回旋余地的,复杂的社会网。     

恒河猴在繁殖笼内的等级结构

有关非人灵长类社群结构的问题,国外已多有研究。许多学者认为无论在野外,或是在捕后(笼养)条件下进行观察都发现只要有几只动物在一起,形成一个群,那末群内的个体之间必然形成等级关系,而这种等级关系是线性排列的。换句话说,如果一群有A、B、C、D、E五只动物的话,它们的等级关系就是这样排列的:A>B>C>D>E。     

Experimental validation of two MIQ scales

Two Minnesota Importance Questionnaire (MIQ) scales, Creativity and Independence were validated by experiment. Subjects were exposed to four task conditions representing joint combinations of high or low levels of Creativity and Independence. As a behavioral criterion of preference, subjects were then required to work for 12 sessions, each session under any (of the four) task condition of their choice. The behavioral results were consistent with the subjects' MIQ score levels on the two scales, thereby validating the scales.     

论罗马天主教关于世界与人的新神学

梵二会议以天主爱他的受造物为出发点,抛弃了仅仅推崇天国而一味否定和贬低世俗世界、人和人的努力的传统立场,肯定了世界上的好的价值以及人的主观努力并赞美世界的进步和人的智慧的积极成果,指出真理的源头在天主,随着真理的发展,世界与天国互相渗透,最终合而为一。同时,梵二会议认为世界和人有或好或坏两种前途,因而必须求得教会的帮助归向天主。
