Comprehending 3D diagrams is critical for success in scientific practice and research demonstrates that understanding of 3D geology diagrams can be improved by making predictive sketches. In mathematics, explaining erroneous examples can support learning. This study combined these approaches to better understand how to effectively support 3D geologic diagram understanding. Participants generated sketches, explained erroneous example sketches, or copied and explained correct sketches. It was hypothesized that generating sketches or explaining erroneous cases would improve understanding, but an open question was whether these conditions would differ from each other. Explaining erroneous examples and sketching improved understanding whereas explaining correct sketches did not. Further, explaining erroneous examples was a more efficient strategy than sketching. These results indicate that erroneous examples can be effective for supporting 3D diagram comprehension and may be a practical substitute for some traditional sketching activities in the context of real classrooms where class time is limited. 相似文献

One of the most compelling questions still unanswered in neuroscience is how consciousness arises. In this article, we examine visual processing, the parietal lobe, and contralateral neglect syndrome as a window into consciousness and how the brain functions as the mind and we introduce a mechanism for the processing of visual information and its role in consciousness. We propose that consciousness arises from integration of information from throughout the body and brain by the thalamus and that the thalamus reimages visual and other sensory information from throughout the cortex in a default three-dimensional space in the mind. We further suggest that the thalamus generates a dynamic default three-dimensional space by integrating processed information from corticothalamic feedback loops, creating an infrastructure that may form the basis of our consciousness. Further experimental evidence is needed to examine and support this hypothesis, the role of the thalamus, and to further elucidate the mechanism of consciousness. 相似文献

The visual world appears stable despite frequent retinal image movements caused by saccades. Many theories of visual stability assume that extraretinal eye position information is used to spatially adjust perceived locations across saccades, whereas others have proposed that visual stability depends upon coding of the relative positions of objects. McConkie and Currie (1996) proposed a refined combination of these views (called the Saccade Target Object Theory) in which the perception of stability across saccades relies on a local evaluation process centred on the saccade target object rather than on a remapping of the entire scene, with some contribution from memory for the relative positions of objects as well. Three experiments investigated the saccade target object theory, along with an alternative hypothesis that proposes that multiple objects are updated across saccades, but with variable resolution, with the saccade target object (by virtue of being the focus of attention before the saccade and residing near the fovea after the saccade) having priority in the perception of displacement. Although support was found for the saccade target object theory in Experiment 1, the results of Experiments 2 and 3 found that multiple objects are updated across saccades and that their positions are evaluated to determine perceived stability. There is an advantage for detecting displacements of the saccade target, most likely because of visual acuity or attentional focus being better near the fovea, but it is not the saccade target alone that determines the perception of stability and of displacements across saccades. Rather, multiple sources of information appear to contribute. 相似文献

We conducted a series of experiments to explore how the spatial configuration of
objects influences the selection and the processing of these objects in a visual
short-term memory task. We designed a new experiment in which participants had
to memorize 4 targets presented among 4 distractors. Targets were cued during
the presentation of distractor objects. Their locations varied according to 4
spatial configurations. From the first to the last configuration, the distance
between targets’ locations was progressively increased. The results revealed a
high capacity to select and memorize targets embedded among distractors even
when targets were extremely distant from each other. This capacity is discussed
in relation to the unitary conception of attention, models of split attention,
and the competitive interaction model. Finally, we propose that the spatial
dispersion of objects has different effects on attentional allocation and
processing stages. Thus, when targets are extremely distant from each other,
attentional allocation becomes more difficult while processing becomes easier.
This finding implicates that these 2 aspects of attention need to be more
clearly distinguished in future research. 相似文献

An animal's behavior is affected by its cognitive abilities, which are, in turn, a consequence of the environment in which an animal has evolved and developed. Although behavioral ecologists have been studying animals in their natural environment for several decades, over much the same period animal cognition has been studied almost exclusively in the laboratory. Traditionally, the study of animal cognition has been based on well‐established paradigms used to investigate well‐defined cognitive processes. This allows identification of what animals can do, but may not, however, always reflect what animals actually do in the wild. As both ecologists and some psychologists increasingly try to explain behaviors observable only in wild animals, we review the different motivations and methodologies used to study cognition in the wild and identify some of the challenges that accompany the combination of a naturalistic approach together with typical psychological testing paradigms. We think that studying animal cognition in the wild is likely to be most productive when the questions addressed correspond to the species’ ecology and when laboratory cognitive tests are appropriately adapted for use in the field. Furthermore, recent methodological and technological advances will likely allow significant expansion of the species and questions that can be addressed in the wild. 相似文献

This paper investigates how it is that a child has become an abuser, and by what means that process may be deconstructed. We know that abusers generally have a childhood history of abuse, though not necessarily sexual. Since not all children who have been traumatised repeat those patterns, and inflict abuse on others, then something must have happened for these particular children in response to their abuse. The author elaborates the view that there is no such thing, to paraphrase Winnicott, as ‘an abused child’ – no such child, that is, separate from the world of the relationships that formed him. He draws on the conceptualisation by Bentovim of an interlocking set of roles described as a ‘trauma organised system’; this notion reflects the fact that the child is a product not just of his specifically traumatic experiences but of a milieu in which power and control is exerted by someone who has typically succeeded in neutralising any caring function in a family in order to bring about the exploitation of a child. Clinical material is presented from the intensive psychotherapy of a nine-year-old boy, who happened also to be a refugee, for whom abusive family dynamics dominated his internal world. He was found to have identified with the abuser, his own father, in order to escape the pain of his victim self and was threatening to act this out in the treatment, making the therapist into a victim. Management of the treatment setting by the inclusion of a benign parental figure enabled the acting out to be contained. Symbolisation of the child’s inner conflicts became possible through play. As the abuser self was contained so the child’s victim experiences could be processed. The conclusion is drawn that engaging therapeutically with the residues of trauma from the beginning of treatment is essential in working with young people who have abused. 相似文献

Visual modules can be viewed as expressions of a marked analytic attitude in the study of vision. In vision psychology, this attitude is accompanied by hypotheses that characterize how visual modules are thought to operate in perceptual processes. Our thesis here is that there are what we call “intrinsic reasons” for the presence of such hypotheses in a vision theory, that is, reasons of a deductive kind, which are imposed by the partiality of the basic terms (input and output) in the definition of a module, and by peculiar characteristics of those terms. Specifically, we discuss three hypotheses of functional attributes: successive stages in the action of modules, residual indeterminacy of their effects, and the role of prior constraints. For each of the three, we indicate its occurrence in perceptual psychology, explain corresponding intrinsic reasons, and illustrate such reasons with examples. 相似文献

Modern technological means allow for meaningful interaction across arbitrary distances, while human morality evolved in environments in which individuals needed to be spatially close in order to interact. We investigate how people integrate knowledge about modern technology with their ancestral moral dispositions to help relieve nearby suffering. Our first study establishes that spatial proximity between an agent's means of helping and the victims increases people's judgement of helping obligations, even if the agent is constantly far personally. We then report and meta-analyse 20 experiments elucidating the cognitive mechanisms behind this effect, which include inferences of increased efficaciousness and personal involvement. Implications of our findings for the scientific understanding of ancestral moral dispositions in modern environments are discussed, as well as suggestions for how these insights might be exploited to increase charitable giving. Our meta-analysis provides a practical example for how aggregating across all available data, including failed replication attempts, allows conclusions that could not be supported in single experiments. 相似文献
