In Experiment 1, rats were trained in a symbolic delayed matching-to-sample task to discriminate sample stimuli that consisted of sequences of magazine light flashes. The intertrial interval was illuminated by the houselight for Group Light, and it was dark for Group Dark. Retention functions exhibited a choose-many response bias when the delay interval was illuminated by the houselight in both groups, and no consistent response bias when the delay interval was dark. In Experiment 2, rats were trained to discriminate sample stimuli that consisted of sequences of tone bursts. During delay testing, a different tone (i.e., different frequency and location than the sample tone) was present or absent during the delay interval. The retention functions exhibited a significant choose-many bias when tone was present during the delay and a choose-few bias when tone was absent. Asymmetrical retention functions for tone burst and light flash sequences are due to the similarity between the stimulus conditions of the delay interval and the modality of the sequential event being discriminated. These results are consistent with an instructional ambiguity explanation of response biases in memory for number. 相似文献

The relationship between the subjective well-being of parents and their own 12–16-year-old children was explored in a Spanish
sample of N = 266 families. A positive relationship was expected due to both a shared environment and the possibility of the genetic
transmission of subjective well-being ‘set-points’. A positive significant relationship was found for the summated scale of
satisfaction domains forming the Personal Well-being Index, and for the specific domains of health and security for the future.
However, no relationship was found for the other five domains that make up this Index or for satisfaction with life as a whole.
We conclude while these results provide some evidence for the expected influence of a shared environment, they have failed
to provide evidence for high heritability of set-points for subjective well-being. 相似文献

In this paper we study the definability and decidability of binary predicates for time granularity in monadic languages interpreted over finitely and infinitely layered structures. We focus our attention on the equi-level (respectively equi-column) predicate constraining two time points to belong to the same layer (respectively column) and on the horizontal (respectively vertical) successor predicate relating a time point to its successor within a given layer (respectively column). We give a number of positive and negative results by reduction to/from a wide spectrum of decidable/undecidable problems. 相似文献

Many cells use calcium signaling to carry information from the extracellular side of the plasma membrane to targets in their
interior. Since virtually all cells employ a network of biochemical reactions for Ca2+ signaling, much effort has been devoted to understand the functional role of Ca2+ responses and to decipher how their complex dynamics is regulated by the biochemical network of Ca2+-related signal transduction pathways. Experimental observations show that Ca2+ signals in response to external stimuli encode information via frequency modulation (FM) or alternatively via amplitude modulation
(AM). Although minimal models can capture separately both types of dynamics, they fail to exhibit different and more advanced
encoding modes. By arguments of bifurcation theory, we propose instead that under some biophysical conditions more complex
modes of information encoding can also be manifested by minimal models. We consider the minimal model of Li and Rinzel and
show that information encoding can occur by AM of Ca2+ oscillations, by FM or by both modes (AFM). Our work is motivated by calcium signaling in astrocytes, the predominant type
of cortical glial cells that is nowadays recognized to play a crucial role in the regulation of neuronal activity and information
processing of the brain. We explain that our results can be crucial for a better understanding of synaptic information transfer.
Furthermore, our results might also be important for better insight on other examples of physiological processes regulated
by Ca2+ signaling. 相似文献

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. 相似文献

Expanding on Jung’s use of the role of the superior and inferior functions, Angelo Spoto advances a new typological model based on ‘whole type’ that utilizes a typological perspective on the archetypal Self. In this new model four cognitive modes taking superior positions are developed in the first half of life and four cognitive modes taking inferior positions are encountered in the second half of life. This model indicates that type development and type dynamics take place through the holding of the tension of opposites between superior and inferior functions, helped by the transcendent function operating differently in the first and second halves of life. Specifically, in the first half of life, the transcendent function produces a tertium that moves typological development along to consolidate an ego-pattern. In the second half of life, the transcendent function takes the individual into encounters having to do with an appreciation of sacrifice, transformation, and symbol-making, as the personality advances towards a greater awareness of wholeness, by way of the inferiors. 相似文献
