重复线索化和靶子注意定向对返回抑制的影响

在返回抑制范式下 ,利用线索—靶子模式进行了两个实验 ,以大学生为被试 ,以重复线索化次数来操纵线索化阶段的注意 ,以靶子的注意定向来操纵靶子加工阶段的注意 ,探讨注意对返回抑制的影响。实验一采用连续线索化方式 ,发现当靶子为自主性注意定向时 ,线索化次数对返回抑制有显著影响 ,线索化 3次时返回抑制值大于线索化 1次和 2次 ;当靶子为反射性注意定向时 ,线索化次数对返回抑制无影响。实验二采用交叉线索化方式 ,发现线索化次数对返回抑制的影响正好与实验一相反。两个实验一致表明 ,无论是线索化阶段的注意 ,还是靶子加工阶段的注意 ,均对返回抑制有显著影响 ;并且 ,在对返回抑制的影响上 ,二者存在显著交互作用。从而支持注意影响返回抑制的观点。该结果对返回抑制的机制研究有一定意义。     

Plural Logic and Sensitivity to Order

Sentences that exhibit sensitivity to order (e.g. John and Mary arrived at school in that order and Mary and John arrived at school in that order) present a challenge for the standard formulation of plural logic. In response, some authors have advocated new versions of plural logic based on fine-grained notions of plural reference, such as serial reference [Hewitt 2012] and articulated reference [Ben-Yami 2013]. The aim of this article is to show that sensitivity to order should be accounted for without altering the standard formulation of plural logic. In particular, sensitivity to order does not call for a fine-grained notion of plural reference. We point out that the phenomenon in question is quite broad and that current proposals are not equipped to deal with the full range of cases in which order plays a role. Then we develop an alternative and unified account, which locates the phenomenon not in the way in which plural terms can refer, but in the meaning of special expressions such as in that order and respectively.     

Repetition effect in visual recognition of letters

This study examined the influence of the repetitive presentation of a letter on the recognition of two letters. In two experiments(4), two letters, which were either identical or not, were presented successively for a short duration at different spatial locations, and the subjects were required to identify them. In Experiment 1, the presentation time of the first letter was varied, whereas that of the second letter was constant. The results revealed that a reduced performance in identifying a second letter was observed in the case that the first letter, which was identical to the second letter, could be identified correctly. Experiment 2 examined whether or not this reduction was due to the identity of the visual shape of two letters. The first letter was presented either in the usual vertical orientation or rotated orientation by 180 degrees and the second letter was constantly presented in the usual orientation. The results revealed that a reduced performance in identifying a repeated letter was observed, regardless of the orientation of the first letter. The findings from the two experiments suggested that the identity of the information in memory was a main cause of the interference effect by repetition.     

Virtual reality and the psyche. Some psychoanalytic approaches to media addiction

This paper explores the ramifications of excessive use of media on personality development, the development of symbolic and thinking functions and on psychic reality. In doing so, the questions of whether there are specific media objects possessing an intrinsic symbolic quality, and which attachments in the inner world of a child/adolescent can be mobilized or destroyed are discussed. By selecting specific material, computer gamers use their game to activate the field of a personal psychic reality. Hereby, they attempt some kind of self‐healing. However, after leaving the game, conflicts and traumata re‐enacted but unresolved in the game disappear from their temporary representation without generating any resonance in the gamer's psychic experience. Consequently, although states of mind and affects are activated in the computer game, their processing and integration fail; the game results in a compulsive repetition. The construction and consolidation of retrievable maturation and structural development, the representation of the unrepresentable, succeed in the context of the triangulating analytic relationship, initially through a jointly performed symbolic and narrative re‐experience or the recreation of the game. Theoretical considerations are illustrated by means of clinical vignettes.     

预警、重复学习和反馈对错误记忆的影响——错误记忆的信号检测论分析

本研究用信号检测论分析预警、重复学习和反馈三种变量对错误记忆的影响.实验1考察预警指导语的影响.实验2考察重复学习和反馈的影响.结果表明:预警对被试辨别力和反应偏向的影响不明显,对错误记忆影响也不显著;重复学习不能明显影响被试的反应标准,但可提高辨别力减弱错误记忆;反馈明显使被试倾向于使用更为宽松的反应标准,难以降低错误记忆.再认双加工模型和激活/监测理论能对实验结果做出合理的解释.     

Effects of repetition on age differences in associative recognition

The study reported here examined the effect of repetition on age differences in associative recognition using a paradigm designed to encourage recollection at test. Young and older adults studied lists of unrelated word pairs presented one, two, four, or eight times. Test lists contained old (intact) pairs, pairs consisting of old words that had been studied with other partners (rearranged lures), and pairs consisting of two unstudied words (new lures). Participants gave old/new responses and then indicated whether their responses were based on details that they could recollect or on familiarity. Older adults exhibited an ironic effect of repetition—an increase in false alarms on rearranged lures with more study opportunities—whereas young adults did not. Older adults also claimed to recall details of the study episode for rearranged lures whose constituent words were presented more frequently, but this was not true for young adults. Although both young and older adults said that they based correct rejections of rearranged lures on memory for details of the study episode, this effect was stronger for young adults. The observed age differences are consistent with older adults having reduced use of recollection in associative recognition tasks.
