Influence of social conditions in song sharing in the adult canary

In songbirds, experience of social and environmental cues during a discrete period after birth may dramatically influence song learning. In the canary, the ability to learn new songs is assumed to persist throughout life. The aim of the present study was to investigate whether social context could guide changes in adult song. Three groups of canaries were kept in different social and temporal conditions. Results showed that the multiple hierarchical levels of the canary song structure were affected by social environment: songs of males housed together for 2 years were more similar than those of males that spent the same time in individual cages in regard to acoustic parameters, syllable repertoire and repertoire of sequences of two-syllable types. However, social housing did not result in the emergence of a group-specific vocal signature within songs. In conclusion, these results suggested that under the influence of social factors, a copying process could allow adult canaries to adjust, at least in part, their songs to those of other individuals.     

Memory for words location in writing

In two experiments, we investigated memory for words location after writing a text. Experiment 1 demonstrated the existence of a memory for words location in writing by showing that participants who first composed a text and were then asked to locate words extracted from their text performed above a chance level established using a computer simulation, and better than participants who did not compose a text but were told the subject of the text. Experiment 2 showed that memory for words location in writing is mainly supported by a visuospatial representation of the text, as indicated by the lower recall of words location by participants who performed a visuospatial concurrent task at the time of the composition, compared with participants who performed a verbal concurrent task. The findings highlight the role of a spatial representation of the physical layout of the text and the role of such a memory in the writing process.

Is Liang Shuming 梁漱溟 Ultimately a Confucian or Buddhist?

Liang Shuming has been proclaimed the forerunner of Contemporary Neo-Confucianism. However, assessing Liang’s identity appears a much more complicated task. Taking a closer look at his copious writings on religion, this paper shows how Liang conceived the role of religion at the different steps of humanity’s quest. Applying this frame of understanding to twentieth century China, Liang saw a discrepancy between the task required in our present time and what the future was holding. Therefore, while he engaged the world in a certain way, he was still holding privately another belief. This “secret” of Liang reshuffles traditional boundaries between the secular and transcendence.     

Valued Relations Aggregation with the Borda Method

The Borda method is a well-known method used to aggregate a profile of crisp binary relations into one weak order. We present a generalization of the Borda method, allowing it to aggregate a profile of valued relations. We give a characterization of the Borda method in this context and we show some links with the PROMETHEE method.     

Models for a paraconsistent set theory

In this paper the existence of natural models for a paraconsistent version of naive set theory is discussed. These stand apart from the previous attempts due to the presence of some non-monotonic ingredients in the comprehension scheme they fulfill. Particularly, it is proved here that allowing the equality relation in formulae defining sets, within an extensional universe, compels the use of non-monotonic operators. By reviewing the preceding attempts, we show how our models can naturally be obtained as fixed points of some functor acting on a suitable category (stressing the use of fixed-point arguments in obtaining such alternative semantics).     

Before and after the vocabulary spurt: two modes of word acquisition?

This paper focuses on early lexical development, and especially the period around 18 months known as the vocabulary spurt. We first propose that this period corresponds to a shift from an associationist to a referential lexical acquisition mechanism following the developmental coupling of specific pre‐linguistic and cognitive abilities. This latter mechanism would allow the acquisition of genuine words, i.e. links between phonetically specified sound patterns and object categories. We then review the literature on early lexical acquisition by typically developing infants and infants with Down and Williams syndrome, and report some data that were recently collected on this issue. We conclude that the data so far are congruent with our proposal, but because they remain insufficient, we propose some future research that focuses on the relation between pre‐linguistic and cognitive developments.     

Variability in behavior frequencies and consistency in transactions across seasons in captive Japanese macaques (Macaca fuscata)

Consistent interspecific differences are found in macaque species, ranging from highly hierarchical and nepotistic societies to more tolerant and open social organizations. It still remains to be demonstrated whether intraspecific variation is narrower than interspecific variation. Herein, we quantified social behavior in a captive group of Japanese macaques (Macaca fuscata) to estimate the range of intraspecific variation for a full array of measurements in three different seasons. Despite an increased frequency of aggression found on the part of males during the mating season, the form of the behaviors performed remained relatively unchanged. Transactions during conflicts, approaches, or grooming did not undergo significant variations in relation to season. Frequencies and durations seemed more sensitive to demographic and environmental variations. The values measured in the study group are representative of the Japanese macaque. The results validate the use of transaction measurements in interspecific comparisons, providing that additional factors such as age and sex are taken into account. Aggr.

Self‐affirmation,political value congruence,and support for refugees

This research tested the potential for self‐affirmation on left‐ and right‐wing political values to increase behavioral intentions to provide help and assistance to refugees. We present a pilot study defining left‐ and right‐wing values, and a main study in which participants completed either a self‐affirmation task, a group‐affirmation task, or participated in a control condition on values that were either congruent or incongruent with their own political views. Results show that left‐wing oriented participants showed more supportive intentions in the self‐affirmation condition compared to the group‐affirmation and control conditions, independent of values congruency. In contrast, right‐wing participants showed more supportive intentions in the self‐affirmation condition, but only when they affirmed on values that were congruent with their own political views.
