Music in dreams and the emergence of the self

Abstract :  This paper deals with the presence and possible 'meaning' of music in dreams. The author explores a possible meaning of music as the most fundamental human symbolic experience, which directly points to the emergence of the Self from the primal union mystique with the Great Mother. The relationships between acoustic and visual experiences are taken into account as two basic human forms of coming into existence, although wholly different from each other. The role of music in dreams seems to be that of the most direct representation of the emerging Self in its pure, pre-representational form. Therefore, when music appears in dreams, providing there is the activation of an emotional tone, all other elements—visual and verbal—should be considered as the expression of the sense to which the music is pointing. A clinical example is described in order to better express the author's opinions.     

Temporal information coding properties of a network of inhibitory interneurons

Inhibitory interneurons are coupled by electrical and inhibitory synapses and exert a powerful control of the discharges of principal cells. In this paper, the transmission properties of excitatory synaptic inputs by a network of interneurons, are studied by using a computational approach. It is shown that both the rise and decay time constants, describing the time course of the excitatory synaptic inputs, have a strong effect on the output jitter of the fired spikes. Similar results were found by changing the values of the other parameters describing the network. Lastly, it is shown that the presence of the electrical coupling between interneurons confers to the network the capability of transmitting, with less temporal spread, the timing information contained in its inputs.     

从词频和新旧效应探讨再认测验中的定向遗忘

本文采用字表方式,从高低词频和新旧效应角度,探讨内隐和外显测验中定向遗忘效应的存在性及其机制问题。结果发现:(1)低频词在两种测验中都存在定向遗忘效应,而高频词仅存在于外显测验中。(2)两种测验中都存在指示记住的新旧效应,而外显测验中不存在指示忘记的新旧效应。由此推断,测验间在没有"意识和无意识"相互污染的理想情况下,只有外显测验可获得定向遗忘效应;定向遗忘的机制可能是选择性编码机制。     

Visual search is postponed during the attentional blink until the system is suitably reconfigured

J. S. Joseph, M. M. Chun, and K. Nakayama (1997) found that pop-out visual search was impaired as a function of intertarget lag in an attentional blink (AB) paradigm in which the 1st target was a letter and the 2nd target was a search display. In 4 experiments, the present authors tested the implication that search efficiency should be similarly impaired (steeper search slopes at shorter lags). A conventional AB deficit was found, but, contrary to expectations, search slopes were invariant with lag. These results suggest that no search can be carried out during the period of the AB. Instead, the search is postponed until after the 1st target has been processed. The authors conclude that efficient visual search cannot be carried out unless the visual system is configured appropriately for the search task. If the initial configuration is inappropriate, processing of the 2nd target is held in abeyance until the system has been suitably reconfigured.     

爬行经验与婴儿空间认知能力的发展

本研究采用“A非B”时间延搁测验对34名9-12个月缨儿的爬行经验与其空间认知能力发展的关系进行了研究。协方差分析表明,婴儿的爬行经验对其在“A非B”延搁任务中表现出来的空间认知能力有显著的主效应,而年龄的效应不明显;进一步分析显示,爬行经验7周以内的婴儿与爬行经验10周以上的婴儿空间认知能力发展水平差异显著。本研究说明,爬行经验与婴儿在“A非B”延搁任务上表现出来的空间认知能力发展有密切的关系。
