Using a combination of reviewing the extensive relevant literature, the author's original scientific research, and exploring the boundaries of human experiences, this article develops a model for consciousness. As a consequence, consciousness is elevated in the scientific understanding of the structure of the Universe, possibly enabling easier interpretation of such concepts as the anthropic principle and quantum physics. The handling of information is a key, leading to a review of the Information Field theory, together with a preliminary attempt at striking the appropriate balance between mind and matter. 相似文献

In this article I develop a case for a theory of intelligence incorporating transpersonal dimensions, namely integrated intelligence. Some recent expanded theories of intelligence move into concepts like creativity, wisdom, and emotional intelligence. Yet they remain embedded within mainstream intelligence theory and its reductionist and materialist presuppositions. Although various theorists in consciousness theory have developed transpersonal models that are beginning to be discussed in some mainstream circles, mainstream intelligence theory is yet to address the broader implications of this. Recent changes in the global economy and the needs of populations have created a need for an expanded theory of intelligence, and more intuitive thinking. 相似文献

Three experiments examined aspects of the link between focus of attention, manipulated by use of video camera and monitor, and paranoid and depressive cognitions in a sample of college students. In Experiment 1 participants were exposed to either a failure or neutral task, under high (HSA) or low self-awareness (LSA) conditions. HSA triggered paranoid cognitions on neutral and failure tasks; failure alone triggered depressive cognitions. In Experiment 2 the camera switched focus thrice between participant and experimenter using only neutral tasks. Paranoia scores initially were higher in the HSA condition. Paranoia scores increased when participants moved from LSA to HSA. Paranoia scores never fell when moving from HSA to LSA conditions. Experiment 3 used only HSA and failure, and showed how a priming task that increased the accessibility of either positive or negative self-cognitions led to significantly different paranoia and depression scores. 相似文献

Associating crossmodal auditory and visual stimuli is an important component of perception, with the posterior superior temporal sulcus (pSTS) hypothesized to support this. However, recent evidence has argued that the pSTS serves to associate two stimuli irrespective of modality. To examine the contribution of pSTS to crossmodal recognition, participants (N = 13) learned 12 abstract, non-linguistic pairs of stimuli over 3 weeks. These paired associates comprised four types: auditory–visual (AV), auditory–auditory (AA), visual–auditory (VA), and visual–visual (VV). At week four, participants were scanned using magnetoencephalography (MEG) while performing a correct/incorrect judgment on pairs of items. Using an implementation of synthetic aperture magnetometry that computes real statistics across trials (SAMspm), we directly contrasted crossmodal (AV and VA) with unimodal (AA and VV) pairs from stimulus-onset to 2 s in theta (4–8 Hz), alpha (9–15 Hz), beta (16–30 Hz), and gamma (31–50 Hz) frequencies. We found pSTS showed greater desynchronization in the beta frequency for crossmodal compared with unimodal trials, suggesting greater activity during the crossmodal pairs, which was not influenced by congruency of the paired stimuli. Using a sliding window SAM analysis, we found the timing of this difference began in a window from 250 to 750 ms after stimulus-onset. Further, when we directly contrasted all sub-types of paired associates from stimulus-onset to 2 s, we found that pSTS seemed to respond to dynamic, auditory stimuli, rather than crossmodal stimuli per se. These findings support an early role for pSTS in the processing of dynamic, auditory stimuli, and do not support claims that pSTS is responsible for associating two stimuli irrespective of their modality. 相似文献

AbstractThe purpose of this study was to investigate the effect of a self-monitoring intervention on the independent completion of dishwashing for three boys with autism (ages 6, 7, and 8) in China. The self-monitoring intervention included visual task analysis, in vivo modeling, self-recording, video self-feedback, and reinforcement. A multiple probe across subjects design was used. Prior to the study, the children had limited or no dishwashing skills, nor did they receive any training on self-monitoring. All three children acquired dishwashing and performed the task independently without supervision one week after the intervention. Their parents were very satisfied with this intervention. 相似文献

ABSTRACTFalse memories created by the Deese/Roediger-McDermott (DRM) paradigm are often accompanied by contextual information. Yet, research investigating the effects of context on false memories is surprisingly scarce. We used the context-dependent memory (CDM) model to construct same versus different context conditions using odours as contexts and DRM lists as to-be-remembered stimuli. Experiment 1 showed that levels of correct recall were higher in the same-context condition than in the changed-context condition, but no effects of context were observed in false recall. Experiment 2 used different odours and a longer retention interval and showed that context-dependent memory effects were found for both true and false memory. For true memory, context reinstatement improved memory, whilst simultaneously reducing false memory. Theoretical and forensic implications of these findings are discussed. 相似文献

The metastable particles in an Al–Zn–Mg–Cu alloy have been examined at atomic-resolution using high-angle annular dark field (HAADF) imaging. In under-aged conditions, thin η′ plates were formed with a thickness of seven atomic planes parallel to the {111}Al planes. The five inner planes of the η′ phase appear to be alternatively enriched in Mg and Zn, with two outer planes forming distinct Zn-rich interfacial planes. Similar Zn-rich interfacial enrichment has also been identified for the η phase, which is a minimum 11-plane thick structure. In rare instances, particles less than seven planes were found indicating a very early preference for seven-layer particle formation. Throughout the aging, the plate thickness appears constant, while the plate radius increases and no particles between 7 and 11 planes were observed. Based on the HAADF contrast, our observations do not support the η′ models previously set forth by other authors. Clear structural similarities between η′ and η were observed, suggesting that drawing distinctions between η′ and η phases may not be necessary or useful. 相似文献

The present study investigates potential age differences in the self-reference effect. Young and older adults incidentally encoded adjectives by deciding whether the adjective described them, described another person (Experiments 1 & 2), was a trait they found desirable (Experiment 3), or was presented in upper case. Like young adults, older adults exhibited superior recognition for self-referenced items relative to the items encoded with the alternate orienting tasks, but self-referencing did not restore their memory to the level of young adults. Furthermore, the self-reference effect was more limited for older adults. Amount of cognitive resource influenced how much older adults benefit from self-referencing, and older adults appeared to extend the strategy less flexibly than young adults. Self-referencing improves older adults’ memory, but its benefits are circumscribed despite the social and personally relevant nature of the task. 相似文献

Upright standing is always environmentally embedded and typically co-occurs with another (suprapostural) activity. In the present study, the authors investigate how these facts affect postural dynamics in an experiment in which younger (M age = 20.23 years, SD = 2.02 years) and older (M age = 75.26 years, SD = 4.87 years) participants performed a task of detecting letters in text or maintaining gaze within a target while standing upright in a structured or nonstructured stationary environment. They extracted the coefficients of drift (indexing attractor strength) and diffusion (indexing noise strength) from the center of pressure (COP) time series in anteroposterior (AP) and mediolateral (ML) axes. COP standard deviation decreased with drift and increased with diffusion. The authors found that structure reduced AP diffusion for both groups and that letter detection reduced younger SD AP (primarily by diffusion decrease) and increased older SD ML (primarily by drift decrease). For older and younger participants, ML drift was lower during letter detection. Further, in older letter detection, larger visual contrast sensitivity was associated with larger ML drift and smaller SD ML, raising the hypotheses that ML sway helps information detection and reflects neurophysiological age. 相似文献
