The organization of spatio-temporal information in an auditory memory task was studied in two experiments. Stimuli consisted of four different configurations of eight sequentially presented beeps. In two configurations, the stimuli were space-time congruent, with (constant or variable) inter-stimulus distances corresponding to (constant or variable) inter-stimulus time intervals. In the other two configurations, the stimuli were space-time incongruent, with (constant or variable) inter-stimulus distances not corresponding to (variable or constant) inter-stimulus time intervals. After a learning phase consisting of 20 presentations of the target configuration, participants reproduced the spatial (Experiment 1) or temporal (Experiment 2) characteristics of the target 60 times in succession without re-examining the target configuration. Accuracy (with respect to the target) and variability (between responses) were found to evolve independently. In the incongruent space-time conditions, effects of variable inter-stimulus time intervals or distances on the reproduction of, respectively, constant distances (Tau effect) or constant time intervals (Kappa effect) were observed, while the reverse was not the case. Thus, dimensional interference occurred when the dimension to be ignored was variable. The results are discussed in the light of the distinction between properties of the stabilized mental image and the process of stabilization.  相似文献

What distinguishes a whole from an arbitrary sum of elements? I suggest a temporal and causal oriented approach. I defend two connected claims. The former is that existence is, by every means, coextensive with being the cause of a causal process. The latter is that a whole is the cause of a causal process with a joint effect. Thus, a whole is something that takes place in time. The approach endorses an unambiguous version of Restricted Composition that suits most commonsensical intuitions about wholes.  相似文献

A task like “moving a meeting forward” reveals the ambiguity inherent in temporal references. That speakers of U.S. English do not agree on how to solve it is well established: Roughly one half moves the meeting futurewards, the other half pastwards. But the extent to which individual speakers, rather than groups of speakers, consider such phrases as ambiguous has not been scrutinized. Does the split in readings result from a lack of intraindividual consistency or from a lack of interindividual consensus? And how specific is U.S. English in this regard when compared to other closely related Germanic languages? Based on a taxonomy of spatiotemporal frames of reference (FoRs), we conducted two experiments with speakers of Swedish, U.S. English, and German to assess individual preferences for temporal FoRs, intra- and cross-linguistic variability, consistency and long-term stability of these preferences, and possible effects of priming a spatial FoR. The data reveal cross-linguistic differences, both in terms of which temporal FoRs speakers prefer (the absolute FoR in Sweden, the intrinsic FoR in German, and both of these in the US) and in terms of the extent to which these preferences are shared and stable (high consensus and consistency in Sweden and Germany, and low consensus and partial consistency in the US). Overall, no effect of spatial priming was observed; only speakers of U.S. English with a baseline preference for the absolute temporal FoR seemed to be susceptible to spatial priming. Thus, the assumption that temporal references are affected by spatial references is only weakly supported.  相似文献

The standpoint that three fundamentally inequivalent classes of system behavior exist, which deserve separate tools for their characterization, is developed. These classes are: determinism, pattern generation, and information. A simple explanation for the origin of these classes is given. The three classes are shown to correspond to the different possible ways in which the properties of the components of a system unfold in the course of the system's processes. Determinism will be defined as a form of causation in which the properties causing the behavior are factually the same as the ones which for the observer specify the current conditions of the system. As a consequence, deterministic systems can be characterized by state equations that describe how the observable properties change. Pattern generation is characterized here as a form of causation in which the observable properties and the behavior‐generating properties correspond to each other as one to the many. Consequently, we experience in terms of the observable properties a branching behavior which is characterized by a pattern of selections at the branching points, a pattern that stands in close correspondence with the visually perceivable patterns and forms, generated by the system's dynamics. Information will be understood as a name for a process and an instance of causation where properties that cause behavior differ from those which we directly observe. The behavior of the system appears to be a consequence of the content of information hidden in the components. This information is, in turn, epistemologically equivalent to the very causal process in which it is unfolded.  相似文献

Does a visual percept emerge to consciousness in a graded manner (i.e. evolving through increasing degrees of clarity), or according to a dichotomous, “all-or-none” pattern (i.e. abruptly transitioning from unawareness to awareness)? The level of processing hypothesis (LoP; B. Windey and A. Cleeremans, 2015) recently proposed a theoretical framework where the transition from unaware to aware visual experience is graded for low-level stimulus representations (i.e. stimulus “energy” or “feature” levels) whereas it is dichotomous for high-level (i.e. the perception of “letters”, “words” or “meaning”) stimulus perception. Here, we will critically review current behavioral and brain-based evidence on the LoP hypothesis and discuss potential challenges (such as differences in LoP conceptualizations, awareness scale related issues, attentional confounds and divergences on experimental factors or statistical analyses) which might be of use for future research within the field. Overall, the LoP hypothesis is a recent and promising proposal that attempts to integrate divergent evidence on the graded vs. dichotomous emergence of awareness debate. Whereas current evidence validates some of the assumptions proposed by the LoP account, there is still much work to do on both methodological and experimental levels. Future neuroimaging studies might help to disentangle the current complex pattern of results found in LoP studies and, importantly, shed some light on the ongoing debate about the search for the Neural Correlates of Consciousness (NCC).  相似文献

Cultural disparity – the variation across cultural traits such as knowledge, skill, and belief – is a complex phenomenon, studied by a number of researchers with an expanding empirical toolkit. While there is a growing consensus as to the processes that generate cultural variation and change, general explanatory frameworks require additional tools for identifying, organizing, and relating the complex causes that underpin the production of cultural disparity. Here I develop a case study in the cognitive science of religion and demonstrate how concepts and distinctions drawn from work on contrastive explanation and manipulationist accounts of causation provide such tools for distinguishing explanatory levels, organizing causal narratives, and accounting for cross-cultural patterns.  相似文献

Observing others’ pain may induce a reaction called personal distress that may be influenced by top-down (imagine self or other in pain, i.e., self- vs other-oriented stance) and bottom-up (physical perspective of those who suffer, i.e., first vs third person perspective- 1PP vs 3PP) processes. The different contributions of these processes have not been teased apart. By capitalizing on the power of Immersive Virtual Reality, we explored how behavioural (subjective ratings) and physiological reactivity (skin conductance reactivity, SCR) to pain and pleasure delivered to an avatar was influenced by Cognitive stance and Physical perspective. Taking an Other-Oriented stance leads to attributing higher congruent valence (i.e. pain rated as unpleasant and pleasure as pleasant) and intensity to the stimuli and induces reduced SCR. Ownership over the virtual limb was maximal in 1PP where physiological reactivity to the stimuli was comparable. Our results highlight different components underpinning reactivity to pain and pleasure.  相似文献

Although borderline patients are suitable for it, they often undergo repeated testing of phantasies against objective reality without success. A reason for these partial failures is that subjects have not been able to build a solid sense of reality and have found many diffi culties for processing reality demands and possibilities. The author puts forward some thoughts on this question, such as the importance of working through the depressive position and the Oedipus complex in the process of building up a solid sense of reality. A sense of reality also favours continuous reality processing. When reality processing becomes as continuous as life itself, the repetition of individual reality tests becomes less frequent and necessary, and more satisfying. The author also presents some recommendations for the psychoanalytic treatment of such patients, stressing the importance and the diffi culties of the introduction of the borderline patient into the triangular situation because primitive defences‐such as disavowal and denial‐are mobilized.  相似文献

Following a naturalist-realist point of view, this paper attempts to contribute to the metaphysical question of whether or not reality includes aesthetics. During evolution, cognitive agents have constructed (goal-directed) regulatory abilities forming anticipatory contents in the form of feelings regarding opportunities for interaction. These feelings are considered to be the fundamental part of an evaluative or (what in this paper considered as aesthetic) behavior through which agents show a preference to aspects of their external world. Thus, ‘aesthetic’ denotes an agential behavior based on an organization of processes integrated in a form that identifies, evaluates, and compares sources of interaction-success or error in specific aspects of external reality. While agents approach the same aspects of reality as they all interact with the same world, our claim is that aesthetic normativity cannot be an objective feature of this reality. This model overcomes problems of correspondence in the sense that an agent's actions and thoughts ought to react to any pre-given (aesthetic) quality or norm, while at the same time it emphasizes the self-directedness of aesthetic behavior that enables the development of creative forms of cognition.  相似文献

The aim of this paper is to defend the causal efficacy of consciousness against two specters of epiphenomenalism. We argue that these challenges are best met, on the one hand, by rejecting all forms of consciousness-body dualism, and on the other, by adopting a dynamical systems approach to understanding the causal efficacy of conscious experience. We argue that this non-reductive identity theory provides the theoretical resources for reconciling the reality and efficacy of consciousness with the neurophysiology of the brain and body.

According to the levels-of-processing hypothesis, transitions from unconscious to conscious perception may depend on stimulus processing level, with more gradual changes for low-level stimuli and more dichotomous changes for high-level stimuli. In an event-related fMRI study we explored this hypothesis using a visual backward masking procedure. Task requirements manipulated level of processing. Participants reported the magnitude of the target digit in the high-level task, its color in the low-level task, and rated subjective visibility of stimuli using the Perceptual Awareness Scale. Intermediate stimulus visibility was reported more frequently in the low-level task, confirming prior behavioral results. Visible targets recruited insulo-fronto-parietal regions in both tasks. Task effects were observed in visual areas, with higher activity in the low-level task across all visibility levels. Thus, the influence of level of processing on conscious perception may be mediated by attentional modulation of activity in regions representing features of consciously experienced stimuli.  相似文献

It has been suggested that measures of auditory processing (AP) are sensitive measures of attention resulting in the high comorbidity of auditory processing disorder (APD) and attention deficit/hyperactivity disorder (ADHD). Others have found that selected AP measures share significant variance with memory tasks. The current study investigated the relation between AP measures and various neuropsychological measures presumed to measure attention and memory in 36 children with a mean age of 7.78 years (SD = 1.61) referred to an outpatient facility. Results indicate that AP measures significantly correlated with each other as well as with some measures of attention, memory, and behavior ratings. Results suggest that although AP measures include elements of both attention and memory, these measures also appear to assess processes not tapped by other measures of attention and memory. The correlation of AP measures with parent-and teacher-rated withdrawal, parent-rated somatization, conduct, and depression, as well as teacher-rated attention, anxiety, learning problems, social skills, and leadership suggest that auditory processing problems may manifest in myriad behaviors across settings. Implications for practice and future research are presented.  相似文献

ABSTRACT

Modern research on the efficacy of levels of processing (LoP) tasks on memory has focused on less than 1-day retention delays, while assuming that the observed benefits of deep tasks will continue across remote delays. However, direct tests of the continued benefits of deep processes for accuracy and organisation in remote memory are rare. The current set of experiments, using auditorily-presented lists of scrambled word pairs, tested whether deep LoP tasks produced better free recall and organisation over one week (Experiment 1) and four weeks (Experiments 2 and 3). All experiments revealed significant LoP effects on free recall and organisation at immediate and delayed test, with no effect of intention to remember. However, Experiments 2 and 3 revealed poor recall and organisation at the delayed tests among all of the LoP groups, suggesting that deep processing may not produce highly accessible memories over very long delays.  相似文献

In this paper we examine how English and Mandarin speakers think about time, and we test how the patterns of thinking in the two groups relate to patterns in linguistic and cultural experience. In Mandarin, vertical spatial metaphors are used more frequently to talk about time than they are in English; English relies primarily on horizontal terms. We present results from two tasks comparing English and Mandarin speakers' temporal reasoning. The tasks measure how people spatialize time in three-dimensional space, including the sagittal (front/back), transverse (left/right), and vertical (up/down) axes. Results of Experiment 1 show that people automatically create spatial representations in the course of temporal reasoning, and these implicit spatializations differ in accordance with patterns in language, even in a non-linguistic task. Both groups showed evidence of a left-to-right representation of time, in accordance with writing direction, but only Mandarin speakers showed a vertical top-to-bottom pattern for time (congruent with vertical spatiotemporal metaphors in Mandarin). Results of Experiment 2 confirm and extend these findings, showing that bilinguals' representations of time depend on both long-term and proximal aspects of language experience. Participants who were more proficient in Mandarin were more likely to arrange time vertically (an effect of previous language experience). Further, bilinguals were more likely to arrange time vertically when they were tested in Mandarin than when they were tested in English (an effect of immediate linguistic context).  相似文献

The discussion of the relation of levels of reality to categories is important because categories have often been interpreted as constituting levels of reality. This article explores whether this view is correct, and argues it is not. Categories as such should not be understood to constitute levels of reality, although particular categories may. The article begins with a discussion of levels of reality and then turns to specific questions about categories and how they are related to these levels.  相似文献

Memory is better when repeated learning events are spaced than when they are massed (spacing effect), as well as when material is processed semantically than when it is processed graphemically (levels-of-processing effect). Examination of the relationship between levels of processing and spacing for both deeply and shallowly encoded items has shown a spacing effect for items processed deeply, but not shallowly. A semantic priming account of spacing was proposed to explain the interaction between levels of processing and spacing on memory. The current study manipulated levels of processing and the amount of spacing (lag) that occurred between repetitions of items that were incidentally encoded. Results from Experiments 1A and 1B revealed lag effects in test performance when items were deeply and shallowly encoded. Although these findings are inconsistent with a semantic priming account, they can be interpreted within a reminding account, which is explored in Experiment 2. Results from the second experiment indicate that bringing reminding under conscious control benefited items that were presented at a long lag but not at a shorter lag. Together, this study provides evidence that is difficult to accommodate with a semantic priming account of spacing and instead provides additional support for a reminding account suggesting that automatic and controlled processes may both underlie the reminding process.  相似文献

Dennett’s recent defense in this journal of the heterophenomenological method and its supposed advantages over Husserlian phenomenology is premised on his problematic account of the epistemological and ontological status of phenomenological states. By employing Husserl’s philosophy of science to clarify the relationship between phenomenology and evidence and the implications of this relationship for the empirical identification of ‘real’ conscious states, I argue that the naturalistic account of consciousness Dennett hopes for could be authoritative as a science only by virtue of the very phenomenological evidences Dennett’s method consigns to the realm of fiction. Thus heterophenomenology, qua scientific method, is incoherent.

Historiography of education is not only a question of construction but also of selection. In 19th century history of education was typically a genre of great educators, mostly male and only marginally female. This construct is influential up to now, at least in popular contexts of educational reasoning. The article discusses in the introductory section problems of selection of names and meanings within history of education, and then three types of historiographical writing that are not only concerned with great educators but have larger Philosophical impact. The first type is Herman Nohls history of German progressive education, the second one is Emile Durkheims history of Higher Education in France, and the third one is George Herbert Meads Movements of Thought in 19th Century. The article compares them and discusses their implications for further development of historical writing in education.  相似文献
