时序表征的空间特性

时间是个高度抽象的概念,必须依靠具体的、易感知的事物进行表征。时间表征本质上是隐喻性的,而时间的空间隐喻是时间隐喻表征的原型。受到数字空间表征研究的启示,发现时序表征同样具有空间特性。时序表征具有空间特性具有一定的普遍性,但是在具体的水平或垂直空间维度、“左-右”或“右-左”空间方向上存在一定的灵活性;此外时序能够导致空间注意的转移。     

情境模型中时间和空间维度更新的相互影响

运用移动窗口技术考察情境模型中时间和空间维度同时或序列转变时二者间的相互关系。结果发现：(1)时间和空间同时转变时, 二者存在易化关系, 但时间对空间的易化作用更大; (2)当二者序列转变时, 以中文为材料的结果只发现时间对空间的易化关系, 而以英语为材料的结果则发现存在双向易化关系, 但时间对空间的易化作用更大。据此, 情境模型中的时间和空间维度更新的捆绑－预期假设得到证明。     

时序信息和空间信息在工作记忆中的分离存储

采用相对新近性判断范式（judgments of relative recency）,通过三个实验探讨了工作记忆中时序信息和空间信息的存储方式及其关系。实验一比较了有无空间线索两种条件下时序信息的记忆绩效,结果发现,有无空间线索并不影响对时序信．E-的记忆。实验二和实验三通过控制刺激呈现的视野范围和减少呈现位置的不确定性来利化空间线索,结果表明,时序信息的记忆绩效也不受空间线索的影响。由此推论,工作记忆中的时序信息和空间信息是分离编码存储的,加入空间线索并不能提高时序信息的记忆绩效。     

The Impact of Spatial Cues on Preschoolers' Selective Attention

The effects of spatial arrangement on preschool children's ability to selectively attend were investigated. Three- and 4-year old children were shown a multicolored dollhouse room intended to serve as a special place containing miniature chairs and models of animals. One category of objects was designated as relevant and 1 as irrelevant. Relevant items were placed in each of the apparatus's corners or in the middle of its walls. Children in the corners condition correctly relocated more relevant items than children in the wall or control conditions. The findings suggest that for both age groups, the ability to recall relevant items may be independent of their ability to demonstrate a selective attention strategy.     

The Face of Time: Temporal Cues in Facial Expressions of Emotion

Results of studies reported here indicate that humans are attuned to temporal cues in facial expressions of emotion. The experimental task required subjects to reproduce the actual progression of a target person"s spontaneous expression (i.e., onset to offset) from a scrambled set of photographs. Each photograph depicted a segment of the expression that corresponded to approximately 67 ms in real time. Results of two experiments indicated that (a) individuals could detect extremely subtle dynamic cues in a facial expression and could utilize these cues to reproduce the proper temporal progression of the display at above-chance levels of accuracy; (b) women performed significantly better than men on the task designed to assess this ability; (c) individuals were most sensitive to the temporal characteristics of the early stages of an expression; and (d) accuracy was inversely related to the amount of time allotted for the task. The latter finding may reflect the relative involvement of (error-prone) cognitively mediated or strategic processes in what is normally a relatively automatic, nonconscious process.     

非语言情境中时间加工与空间距离加工的关系

时间加工与空间距离加工的关系主要有两种, 一种是在空距离–空时距以及动物的研究中, 时间加工影响空间距离加工, 空间距离加工影响时间加工, 两者相互影响, 存在对称的干扰, 这种关系与注意和记忆有关。另一种是在实距离–实时距中, 空间距离加工影响时间加工, 而时间加工不受空间距离加工的影响, 时间加工和空间距离加工之间具有不对称的干扰。时空关系的不对称与隐喻理论、人们的感知运动经验和时空信息的显著性有关。神经机制上, 右顶叶皮质、侧顶内区、左顶叶皮质、小脑、前额等参与时间加工和空间距离加工, 但两种加工涉及到的神经机制也有部分差异。未来可以从时间加工的分段性、不同条件下时间加工和空间距离加工的心理机制以及脑机制进行研究。     

The Role of Visual Cues in Movement Control and Motor Memory

3 groups of 12 Ss performed an index finger letter-writing task with visual information but without kinesthetic cues (+V?K), followed immediately by repeating the same letters without vision (?V?K). All groups performed 6 test trials of + V?K, then ?V?K writing. Group 1 had no experience with the task prior to the test trials, Group 2 practiced the letters without vision with kinesthetic cues (?V+K), while Group 3 had visual and kinesthetic practice (+V+K). Visual cues efficiently guided performance in the absence of kinesthesis, and visual memory traces had a marked reinforcing effect. Further, learned reliance on kinesthetic cues was present even in +V?K performance, but reliance on visual cues did not develop.     

系列项目时间和空间信息学习的分组效应研究

运用顺序回忆方法考察分组对系列项目时间和空间信息学习的影响。包括两个实验,实验一考察简化时间上的分组,或事先告知被试分组规则的情况下,分组是否会有助于时间顺序信息的学习。结果发现,这两个操作对时间顺序信息学习的促进作用不显著。实验二考察了垂直维度上不同形式的分组对空间位置信息学习的影响。结果发现,不同的分组方式对空间位置信息学习所起的作用不同。本研究支持了时间和空间两类顺序信息学习的内在过程不同,不应该用同一理论机制进行解释。     

繁衍线索对风险信息加工的影响

进化理论认为风险行为与求偶有关。研究通过比较求偶信息(异性照片或描述异性的词语)、养育后代(孕妇照片)及奖赏信息(金牌照片等)试图进一步探讨繁衍线索对两性知觉和判断风险信息的影响。研究1中, 被试描述理想约会对象后求偶动机得到激发, 相对于描述晴朗天气的控制组, 求偶动机让两性更慢地从高风险信息(如滑雪、冲浪等)转移注意力, 且两性对风险信息的注意转移与社群性向无关。研究2显示, 相对于养育后代和奖赏信息, 求偶信息更为迅速地促使男性对高风险信息做出判断, 但求偶信息让女性比男性更慢地对高风险信息做出判断。研究结果进一步证实了自然选择理论及性选择理论对两性加工风险信息的认知机制具有预测作用。     

Temporal Induction of Missing Birdsong Segments in European Starlings

Four European starlings (Sturnus vulgaris) discriminated a 300-ms segment of starling song from a 300-ms segment of budgerigar song in three contexts in a two-choice key-peck operant discrimination task. In the starling-song context, on each trial, one of the song segments was presented in the context of starling song; in the budgerigar-song context, the segments were presented in the context of budgerigar song. In the no-song context, the song segments were presented outside of a song context. On occasional unreinforced probe trials, the song segments were replaced by either white noise or silence. On noise trials in the two song contexts, but not on silent trials in the song contexts or noise trials in the no-song context, the starlings were significantly more likely to respond to the key associated with the starling song segment than to the key associated with the budgerigar song segment. This effect was especially pronounced in the starling-song context. The results indicate that noise induces perceptual restoration of missing birdsong segments in songbirds.     

The Role of Auditory Cues in the Detection of State Anxiety 1

Detecting anxiety is essential in both help-giving settings and in everyday social relationships. The studies reported here represent a follow-up to an earlier set of studies in which observers (raters) accurately identified others' (expressers') state anxiety using either video-only cues or audio-video cues. The earlier studies had included expressers who were repressors and nonrepressors, while the present studies included only nonrepressors. Observers viewedheard selected segments of previously videotaped expressers' self-reported high and low state anxiety experiences. Surprisingly, unlike the earlier studies, state anxiety was significantly inaccurately evaluated when video-only cues were used, but when audio cues were available, state anxiety was correctly identified. Information in video-only cues seemed to mislead observers since low compared with high state anxiety was rated as more anxious. These studies, and the significant comparison between studies with audio cues present and with audio cues absent, indicate the impact of auditory cues in detecting state anxiety in others.     

视角在时间语言理解中的影响

语言学家在英语的时间语言表达中发现了隐含其中的两种不同运动视角：一种是从过去指向将来的自我运动（自我运动视角moving-ego）;另一种是从将来指向过去的时间运动（时间运动视角moving-time）。心理学家McGlone＆Harding报告了在英语中视角对时问语言理解的作用,并提出人们存在MT视角的偏向。本文报告了两个实验,实验1直接运用和修改McGlone＆Harding的范式在汉语文本探讨视角对时间语言理解的影响。实验2运用信号检测理论来验证了人们存在MT视角偏向。     

The Effects of Spatial Frequency and Temporal Waveform on Three Measures of Temporal Processing

The effects of spatial frequency and temporal transition of sine-wave grating onset and offset were assessed using measures of reaction time, visual persistence, and temporal order judgments. The stimuli were lateralized fields, separated by 1° of visual angle. Slow temporal transition resulted in significantly poorer performance than did abrupt onset and offset, but spatial frequency had a minimal effect. Thus, the latency, temporal resolution, and temporal ordering of events are mediated by a mechanism that is sensitive to abrupt temporal transients. The stimulus conditions employed did not result in a shift in the point of subjective simultaneity.

空间参照系建立的时间特征*

通过2个实验来探讨空间记忆参照系建立的时间特征。被试学习一个由7个物体组成的场景,场景中的物体以随机的方式序列呈现。一个能够标明物体位置且具有对称结构的场景分别在被试进行物体位置学习之前或之后呈现。研究结果发现:当被试在学习物体位置之前短暂呈现场景结构,场景结构能够决定空间参照系的建立;但被试学习物体位置之后再短暂呈现场景结构,场景结构不能决定空间参照系的建立。以上结果表明:空间参照系是在学习物体位置之前建立,并且建立之后不能被改变。     

语言线索对空间关系表征的影响及其机制

语言的获得会对空间认知产生深刻的影响。关于语言与空间认知,近些年来,不仅有大量的相关研究发现语言能力跟空间认知能力之间存在着密切的关联,还出现了实验研究,来试图直接揭示语言对空间关系表征的影响。研究发现,在一系列涉及不同空间关系的任务中,相较于非语言线索,语言线索提示的效果明显更好。在此基础上,从语言编码的特点和加工过程等方面进一步分析语言的作用机制,发现在空间表征中语言主要起到了选择和整合的作用,语言的作用过程是即时性的。建议未来研究在空间任务和语言表述形式上有更多的变式,从而更全面地来揭示语言的作用。     

On the Role of Vertical Texture Cues in Height Perception

When people judge height from the top looking down they tend to overestimate vertical distance. Initial findings suggest that this perceptual bias may be in part due to the experienced fear of falling. However, previous studies did not control for potentially relevant optical invariants, especially vertical texture gradient cues, that may inform such perceptual judgments. In this study, we examined to what degree texture gradient cues may account for the perceptual bias in height perception. To this end, in 2 different conditions in which vertical texture gradient cues were either present or absent, participants provided distance and size judgments from an elevated position (5.68 m) and from the ground. Results revealed a systematic overestimation of vertical extent and object size when judged from a height. Yet, the absence or presence of texture gradient cues did not differentially influence these judgments. Finally, although fear levels were reported to be larger at the elevated position than on the ground, fear levels did not correlate with the perceptual bias, thereby demanding further research into the mechanisms underlying the perceptual bias in height perception.
