Three experiments that investigated alternative accounts of repetition priming are reported. All 3 experiments used semantic comparison tasks and included trials in which each of the 2 words being compared had previously occurred on separate trials. In the re-pair match condition, the response required matched that on the 2 previous trials in which the words had occured. In there-pair mismatch condition, the response required was opposite to that on the previous trials containing the words forming the critical pair. In all 3 experiments, responses were faster and more accurate in the re-pair match condition than in the re-pair mismatch condition. Possible accounts of this effect within the frameworks of instance theory and of transfer appropriate processing are considered. 相似文献

This study inspected the deterministic structure of unipolar depression. Two women self-monitored sadness hourly 10 times a day for 6 months. One woman had a recurrent history of unipolar depression, and the other did not. Data were analyzed by visual inspection, examination of the Fourier transforms of the time plots, and the correlation dimension. Results suggested that in addition to a strong periodic component that existed only within the depressed subject's mood time series, a low-dimensional chaotic process might have been operating. In the nondepressed control subject, no such periodicity or process could be identified. The findings support maladaptive deterministic theories of mood disorders and have implications for the assessment of unipolar depression. 相似文献

The word length effect is the finding that short items are remembered better than long items on immediate serial recall tests. The time-based word length effect refers to this finding when the lists comprise items that vary only in pronunciation time. Three experiments compared recall of three different sets of disyllabic words that differed systematically only in spoken duration. One set showed a word length effect, one set showed no effect of word length, and the third showed a reverse word length effect, with long words recalled better than short. A new fourth set of words was created, and it also failed to yield a time-based word length effect. Because all four experiments used the same methodology and varied only the stimulus sets, it is argued that the time-based word length effect is not robust and as such poses problems for models based on the phonological loop. 相似文献

The application of functional neuroimaging to the study of human emotion has yielded valuable data; however, the conclusions
that may be drawn from any one study are limited. We applied novel statistical techniques to the meta-analysis of 106 PET
and fMRI studies of human emotion and tested predictions made by key neuroscientific models. The results demonstrated partial
support for asymmetry accounts. Greater left-sided activity was observed for approach emotions, whereas neural activity associated
with negative/withdrawal emotions was symmetrical. Support was also found for affect program emotion accounts. The activation distributions associated with fear, disgust, and anger differed significantly. These emotions
were most consistently associated in activity in regions associated with selective processing deficits when damaged: the amygdala,
the insula and globus pallidus, and the lateral orbitofrontal cortex, respectively. In contrast, the distributions for happiness
and sadness did not differ. These findings are considered in the context of conceptualizations of the neural correlates of
human emotion. 相似文献

There are no systemic accounts of Intensive Care Units (ICUs) nor is there much to guide the systemic therapist working within these units. This paper attempts to develop an analysis of ICUs and proposes two working models describing the various levels at which the therapist can intervene. 相似文献

I develop a multilevel, holistic view of persons, emphasizing embodiment, emotions, consciousness, and the social self. In successive sections I draw from six sources: 1. Theology . The biblical understanding of the unitary, embodied, social self gave way in classical Christianity to a body-soul dualism, but it has been recovered by many recent theologians. 2. Neuroscience . Research has shown the localization of mental functions in regions of the brain, the interaction of cognition and emotion, and the importance of social interaction in evolutionary history and child development. 3. Artificial intelligence . Some forms of robotics use embodied systems that learn by interacting with their environment, but the possibilities for emotion, socialization, and consciousness in robots remain problematic. 4. Relations between levels . Concepts that can help us relate studies of neurons and persons include the hierarchy of levels, the communication of information, thebehavior of dynamic systems, and epistemological and ontological emergence. 5. Philosophy of mind . Two-aspect theories of the mind-brain relation offer an alternative between the extremes of eliminative materialism and the thesis that consciousness is irreducible. 6. Process philosophy . I suggest that process thought provides a coherent philosophical framework in which these themes can be brought together. It combines dipolar monism with organizational pluralism, and it emphasizes embodiment, emotions, a hierarchy oflevels, and the social character of selfhood. 相似文献

The feature model (Nairne, 1990) is extended to include order information by incorporating aspects of Estes' (1972, 1997) perturbation theory. Order information is encoded with other cues in primary memory and precision is gradually lost due to drift along the appropriate dimension. Recall begins with the cue whose positional uncertainty gradient indicates it was in the first position with the highest probability. Order errors occur primarily because cues can “perturb” to adjacent positions: Although the appropriate secondary memory target is sampled, it is sampled out of order. However, cues that have not perturbed can also sample an incorrect secondary memory item, which is then recalled out of order. Thus, both order errors and item errors can give rise to recalling an item from the list in an incorrect position. A simulation shows that with the addition of the perturbation mechanism, the feature model can produce the appropriate order error gradients for short and long words recalled in quiet, accompanied by irrelevant speech, or accompanied by articulatory suppression. 相似文献

Active lifestyles might protect cognitive abilities; however, studies rarely consider the reverse causal direction. Activity-cognition associations might reflect stable intelligence differences rather than a protective effect of activity. The Lothian Birth Cohort 1936 (n = 1091) completed cognitive tests aged 70, having taken an intelligence test aged 11. Activity (assessed by participation in 15 activities that produced a socio-intellectual activity factor, and by physical activity) was positively associated with cognition (r = .08 to .32, p ≤ .05). When age-11 IQ and adult social class were controlled, only physical activity remained significantly associated with general cognitive ability and processing speed. 相似文献

Intelligence differences might contribute to true differences in personality traits. It is also possible that intelligence might contribute to differences in understanding and interpreting personality items. Previous studies have not distinguished clearly between these possibilities. Before it can be accepted that scale score differences actually reflect personality differences, personality items should show measurement invariance. The authors used item response theory to test measurement invariance in the five-factor model scales of the International Personality Item Pool (IPIP) and NEO-Five-Factor Inventory (NEO-FFI) across two groups of participants from the Lothian Birth Cohort 1936 with relatively low and high cognitive abilities. Each group consisted of 320 individuals, with equal numbers of men and women. The mean IQ difference of the groups was 21 points. It was found that the IPIP and NEO-FFI items were measurement invariant across all five scales, making it possible to conclude that any differences in IPIP and NEO-FFI scores between people with low and high cognitive abilities reflected personality trait differences. 相似文献
