The extent of the present

One of the principal objections to a tensed or dynamic theory of time is the ancient puzzle about the extent of the present. Three alternative conceptions of the extent of the present are considered: an instantaneous present, an atomic present, and a non-metrical present. The first conception is difficult to reconcile with the objectivity of temporal becoming posited by a dynamic theory of time. The second conception solves that problem, but only at the expense of making change discontinuous. The third conception is the most plausible: that "the present" is a non-metrical notion which must be completed by the mention of some event or interval in order to have a measure, in which case what is present varies with one's context.     

On the nature of interactions between the past and the present.

We conceptualize the past and the present as dimensions of experience and ask whether past processing must affect decisions about the present and whether present processing must affect decisions about the past. The paradigm is speeded classification: Ss classified a stimulus's past spatial position and tried to ignore information about present position (Experiments 1-4), or classified present position, while attempting to ignore past position (Experiments 5-6). We found that in classifying the past, Ss were unable to ignore present position, unless it was processed apart from the retrieval cue. In classifying the present, subjects could ignore past position completely. We conclude that a processing asymmetry exists, reflecting perhaps a logical asymmetry in the information required to make past or present decisions.     

四种注意情境下幼儿自我延迟满足的实验研究

将120名中等自控能力的3～5岁幼儿随机分配到四种注意情境下:两种奖励物同时呈现、只呈现即时奖励物、只呈现延迟奖励物、两种奖励物都不呈现,以探索幼儿自我延迟满足的注意机制及发展特点。结果发现:(1)幼儿自我延迟满足在两种奖励物都不呈现情境下平均延迟时间最长,在呈现奖励物的三种情境下平均延迟时间较短,表现出跨年龄稳定性;(2)3～5岁幼儿自我延迟满足发展存在显著年龄差异,表现出随年龄增长而提高的趋势。     

Witnessing across time: accessing the present from the past and the past from the present

We are used to the idea that trauma in the past interrupts our capacity to grasp the present. But present or recent trauma can have a similar dissociative effect on our capacity to experience the more distant past. Contemporary trauma can rob the past of its goodness, leaving one feeling as if the past is gone, dead, separated from the present. The vitalization of the present by the past or the past by the present requires that experiences be linked across time. These links are created, in both directions, via categories of experience characterized by shared affect (Modell 1990, 2006). Such categories are created, in turn, by metaphor; and the construction of these metaphors across time requires that one be able to occupy self-states in both the past and the present that can then bear witness to one another. Trauma can result in the dissociation of these self-states from one another, leading to a disconnection of present and past.     

Visualized representation of visual search patterns for a visuospatial attention test

Cancellation tests have been widely used in clinical practice and in research to evaluate visuospatial attention, visual scanning patterns, and neglect problems. The aim of the present work is to present a visualized interface for the visuospatial attentional assessment system that can be employed to monitor and analyze attention performance and the search strategies used during visuospatial processing of target cancellation. We introduce a pattern identification mechanism for visual search patterns and report our findings from examining the visual search performance and patterns. We also present a comparison of results across various cancellation tests and age groups. The present study demonstrates that our system can obtain more processing data about spatiotemporal features of visual search than can conventional tests.     

中国大学生幸福评价的时间轨迹

幸福评价的时间轨迹是指人们对自己的过去、现在和将来的幸福评价的轨迹。从过去、现在和将来角度来研究幸福, 对于全面理解幸福本质具有重要的意义。本研究用两项研究探索了中国大学生的幸福评价的时间轨迹。研究1让130名大学生完成时间维度生活满意度量表, 结果发现, 中国大学生认为过去与现在的幸福没有显著区别, 将来比过去和现在都幸福, 即过去幸福=现在幸福 < 将来幸福, 这与西方的研究结果过去幸福 < 现在幸福 < 将来幸福的轨迹不同。研究2采用实验法, 让45名大学生对描述幸福和不幸福的形容词进行评定, 再次支持了中国大学生的这一幸福评价的时间轨迹。不幸福评价的时间轨迹呈现出过去不幸福=现在不幸福 > 将来不幸福的趋势。     

Happiness and Suffering in the Life Story: An Inquiry into Conflicting Expectations Concerning the Association of Perceived Past with Present Subjective Well-Being in Old Age

The study examined whether positive or negative aspects of the life story were predominantly associated with present subjective well-being (SWB). Two samples (N?=?815 and 213; mean ages 75 and 73) rated past emotions (happiness and suffering) in positive and negative anchor periods (e.g., ??the happiest period,?? ??the most miserable period??) of their life stories. The indices of present SWB were present happiness, present suffering, and life satisfaction. Results indicated that when the past emotions were net of each other, past happiness was related to the positive indices, but not to the negative index, of present SWB whereas past suffering was related to the negative index, and only partially to the positive indices, of present SWB. Congruent emotions (happiness in positive periods, suffering in negative periods) were stronger than incongruent emotions (happiness in negative periods, suffering in positive periods), yet each had unique associations with present SWB. Finally, past happiness weakened the inverse relationship between past suffering and present SWB, yet it strengthened this relationship when past emotions were both incongruent (i.e., when happiness in negative periods was analyzed in conjunction with suffering in positive periods). In conclusion, rather than presenting predominance over each other, positive and negative ingredients in the life story maintain complementary and interactive associations with present SWB. In this context, the study points to the SWB-related implications of the interplay between paramount life experiences in the individual??s anchor periods and the emotions that the individual attributes to these periods.     

Effects of experimenter and mother presence on the attentional performance and activity of hyperactive boys

The attentional performance, activity, and off-task behavior of hyperactive boys with and without conduct problems and normal boys were compared on a cancellation task under three conditions: when performing the task alone, with mother present, and with experimenter present. Results indicated that both the hyperactive groups achieved poorer attentional scores than normal subjects in the alone and mother present conditions, but improved in the experimenter present condition. The performance of the hyperactive boys with conduct problems was particularly affected by this condition. The activity and off-task behavior scores of both the hyperactive groups were higher than controls in all conditions, although the hyperactive boys with conduct problems decreased in off-task behavior when the experimenter was present. Attention and behavior scores were not significantly correlated. The implications of these findings for assessment of hyperactivity, and the role of noncompliance in the attentional behavior of hyperactive children, are discussed.This study is based in part on the first author's Ph.D. thesis in the Department of Psychology, University of Melbourne.     

The Others Will Help: The Presence of Multiple Video Game Characters Reduces Helping After the Game Is Over

The bystander effect refers to the phenomenon that individuals are less likely to help if there are potential other helpers present. For instance, past research revealed that participants were less likely to help computer-controlled characters if there were other computer-controlled characters present. Research has also shown that the bystander effect occurs if the presence of others is merely imagined. The present research examined the idea that the presence of multiple characters within a video game reduces the player's helping behavior even after the video game is over. In fact, participants who played a video game with multiple characters present were less likely to devote time to assisting in a future study than participants who had played the same video game with only a single character present.     

A factor analytic and reliability study of the Devereux Child Behavior Rating Scale

The factor structure of the Devereux Child Behavior (DCB) Rating Scale was found to be different in the present study from those reported by the authors of the scale. Five of the 17 DCB factors were too unreliable to include in the present factor analysis. The findings of the present study were strikingly similar with other factor analytic studies of behavior rating scales in that only three main factors were found: Conduct Disorder, Personality Disorder, and Inadequacy-Immaturity.     

Baby X revisited

The present study is a replication of a study reported by Seavy, Katz, and Zalk (1975) in which subjects interacted with a 3-month-old female infant who was either introduced as a boy, a girl, or without any specific gender information. In the present study infants of both genders were used as stimuli, and 60 college undergraduates served as subjects. The results of the present study are similar to the findings of the original investigators. The gender labels provided to the subject resulted in highly sex-stereotyped behavior concerning toy choice.     

6～12岁儿童Flanker任务下的冲突适应效应

为了探讨6～12岁儿童冲突适应能力的发展,本研究使用经典的Flanker任务,考察了181名一至六年级小学生在冲突任务中的成绩。结果发现,冲突效应在各个年龄段都显著,但是冲突效应大小在不同年龄段之间没有显著差异;对于冲突适应效应,在反应时和准确率上都发现了冲突适应的证据,表现为不一致试次后的冲突效应减小和错误率降低,并且,冲突适应效应的大小在各个年龄段也没有差异。以上结果表明,对于6～12岁左右的小学生,冲突适应效应已经稳定存在,并且,不存在年龄差异。     

计算机有内隐记忆吗？——人与计算机的初步比较研究

本实验参照国内内隐记忆研究方面的一个经典实验(杨治良,1991),以无意义音节为材料,运用信号检测论的方法,对计算机是否存在内隐记忆的问题进行了初步的探讨。结果表明,在本实验条件下计算机只有单纯的100％正确的回忆效应,不具备内隐记忆。本研究为探明计算机的记忆特点作了初步尝试,同时也从一个新角度再次证明了内隐记忆是独立于外显记忆的客观存在。     

The A-theory of time and induction

The A-theory of time says that it is an objective, non-perspectival fact about the world that some events are present, while others were present or will be present. I shall argue that the A-theory has some implausible consequences for inductive reasoning. In particular, the presentist version of the A-theory, which holds that the difference between the present and the non-present consists in the present events being the only ones that exist, is very much in trouble.     

The psychological present

The present paper compares behavior-analytic and cognitive treatments of the concept of psychological history with regard to its role in current action. Both treatments take the position that the past bears some responsibility for the present, and are thereby obligated to find a means of actualizing the past in the present. Both do so by arguing that the past is brought to bear in the present via the organism. Although the arguments of the two positions differ on this issue, neither provides a complete account. An unconventional treatment of psychological history is proposed, the logic of which is exemplified in anthropological, biological, and psychological perspectives. The unconventional treatment in psychological perspective holds that (a) the organism's interaction with its environment, not the organism itself, changes with experience; and (b) the past interactions of an organism exist as, and only as, the present interactions of that organism. This solution to the problem of psychological history provides obligations and opportunities for analysis that are not available when the more conventional positions of cognitivism and behavior analysis are adopted.     

An experimental synthesis of the associations and gestalt accounts of the perception of size: Part I

The Associationists state that our everyday impressions of size are a product of past experience. The Gestalt psychologists state that they are immediately or directly given in present experience. The experiment described here suggests that both past and present experience are simultaneously involved, and that a synthesis of the two accounts is required.     

The use of the past and the present in the clinical setting Pasts and presents

The author provides a brief summary of Latin American literature concerning temporality. She shows that a common theme throughout all these papers is that the analytical relationship is considered to be bipersonal and symmetrical, thus demonstrating a concern for establishing the basis by which social subjectivity can be reconsidered. This literature displaces the idea of linear time from its central position and introduces other measures of time. The analytical relationship takes place not only in the past but also in a newly created present. This is the ongoing present, of what is happening now, instantaneous and without a prior history attached to it. This leads the author to suggest that there is a present to one's history and a history to one's present. She then analyses the consequences of this proposition by examining some clinical material where she attempts to pinpoint those instances in which the analyst may have reacted defensively, tending to position himself in the analysand's past instead of being able to take action in the present. Clinical material from the IJP is used.     

The Rights of Future People

ABSTRACT  It has been argued by some that the present non-existence of future persons entails that whatever obligations we have towards them are not based on rights which they have or might come to have. This view is refuted. It is argued that the present non-existence of future persons is no impediment to the attribution of rights to them. It is also argued that, even if the present non-existence of future persons were an impediment to the attribution of rights to them, the rights they will have when they come into existence constitute a constraint on present actions. Both arguments build on a suggestion of Joel Feinberg's. Next, three arguments are considered which, while they do not highlight the non-existence issue, are related to it. The view that the causal dependence, of (some) future people on present policies, erodes or weakens the claim that rights considerations should constrain our present actions concerning them, is considered and rejected. The view that future people can only have rights to what is available at the time at which these people come into existence is considered and rejected. So too is the view that the attribution of rights to future people involves, in virtue of resource scarcity, an unacceptable arbitrariness.     

Flow and structure of time experience – concept,empirical validation and implications for psychopathology

We present a conceptual framework on the experience of time and provide a coherent basis on which to base further inquiries into qualitative approaches concerning time experience. We propose two Time-Layers (Macro-Layer and Micro-Layer) and two Time-Formats (Flow and Structure) forming four Time-Domains. Micro-Flow and Micro-Structure represent the implicit phenomenal basis, from which the explicit experiences of Macro-Flow and Macro-Structure emerge. Complementary to this theoretical proposal, we present empirical results from qualitative content analysis obtained from 25 healthy participants. The data essentially corroborate the theoretical proposal. With respect to Flow, the phenomenally accessible time experience appeared as a continuous passage reaching from the past through the present into the future. With respect to Structure, the individual present was embedded in the individual biography, emerging from past experiences and comprising individual plans and goals. New or changing plans and goals were being integrated into the existing present, thus forming a new present. The future appeared as changeable within the present, by means from the past, and therefore as a space of potential opportunities. Exemplarily, we discuss these results in relation to previous empirical findings on deviant experiences of time in Autism Spectrum Disorder (ASD) that is presumably characterized by a breakdown of Flow and concomitant compensatory repetition resulting in an overly structured time. Finally, we speculate about possible implications of these findings both for psychopathological and neuroscientific research.
