Relative sensitivity of the mutual exclusivity and novel-name-nameless category assumptions

The mutual exclusivity (ME) assumption states that children affix a novel label to only one unfamiliar object, while the novel-name-nameless category (N3C) assumption states that children affix a novel label to multiple unfamiliar objects. To compare the relative sensitivity of the two assumptions, two types of tasks, with two trials in each, were given to 5-year-olds. In the first trial of each task, all children selected only the unfamiliar object for a novel label, which was consistent with the ME assumption. For the task which did not have the same unfamiliar object in the two trials, 94% of the children selected the object with the same shape but black-white reversed image in the second trial, which was consistent with the N3C assumption. For the task which had the same unfamiliar object in the two trials, 43% of the children selected the same object in the second trial, which was consistent with the ME assumption, and 48% of them selected the object with the same shape but reversed image, which was consistent with the N3C assumption. The findings suggest that the ME and N3C assumptions can be flexibly applied to children's word learning.     

Spread of Risk Information Through Microblogs: Twitter Users with More Mutual Connections Relay News That is More Dreadful1

In elucidating the spread of risk information through microblogging, it is important to understand the behaviors of numerous average users, in addition to the activities of authorities. We followed the transmission pathways of 10 actual widely spread tweets concerning several risk information topics, including natural disasters, nuclear disasters, and infectious diseases, and we identified the types of risk that affected retweeting by classifying each tweet based on Slovic's risk-perception model. Furthermore, we examined the types of users who did and did not retweet the information. Users with few connections in the form of followers (i.e., people who are following a user) or followees (people a user is following), or with a low ratio of mutual followers within their connections, had a tendency to retweet a large amount of risk information, regardless of the type of risk involved. On the other hand, users with a high ratio of mutual followers exhibited a greater tendency to retweet risk information when it was perceived as dreadful, though they did not retweet risk information much on the whole. These results suggest that there are two mechanisms by which risk information is spread within the Twitter network: information exchange and social sharing of personal reactions.     

Environmental coupling modulates the attractors of rhythmic coordination

A simple instance of coupling behavior to the environment is oscillating the hands in pace with metronome beats. This environmental coupling can be weaker (1 beat per cycle) or stronger (2 beats per cycle). The authors examined whether strength of environmental coupling enhanced the stability of in-phase bimanual coordination. Detuning by manipulanda that produced different left and right eigenfrequencies shifted the relative phase angle from 0 degrees, with the size of the shift larger for higher movement frequencies. Stronger environmental coupling was found to decrease this relative-phase shift, with accompanying increase and reduction, respectively, in recurrence quantification measures related to coordination stability and coordination noise. Stronger environmental coupling also increased oscillation amplitude. Results are considered from the perspective of parametric stabilization.     

Experimental study on co-evolution of categorical perception and communication systems in humans

In this paper, we present an experiment that integrates a semiotic investigation with a dynamical perspective on embodied social interactions. The primary objective is to study the emergence of a communication system between two interacting individuals, where no dedicated communication modalities are predefined and the only possible interaction is very simple, non-directional, and embodied. Throughout the experiment, we observe the following three phenomena: (1) the spontaneous emergence of turn-taking behaviour that allows communication in non-directional environments; (2) the development of an association between behaviours and perceptive categories; (3) the acquisition of novel meaning by exploiting the notion of complementary set theory.     

Beyond the logic of Lemma: the oneness of life and its environment,the oneness of within and without

In this paper the ‘analyst as a citizen in the world’ is understood as the analyst interconnecting and harmonising with his or her environment, including not only society, but also nature and the universe. In this sense, Buddhism teaches the Oneness of Life and its Environment, and links are made between Mahayana Buddhism and Jung's understanding of the Self and individuation. The Logic of Lemma in the Flower Ornament Sutra indicates that all phenomena in the world can merge with each other without losing individuality; ten stages are described from the Lotus Sutra and links are made with the development in respect to the ego; Kenji Miyazawa and his work are given as examples to illustrate this. Causality and synchronicity are explored in terms of the interaction between the individual and the environment, and three examples are given where sometimes individual, egoic, causality is more of a feature and sometimes synchronicity has a greater prominence. The paper ends with an examination of tree drawings, made over a period of 50 years by junior high school students, which indicates the way that these individuals have portrayed themselves and their relation to their environment.     

General Need for Autonomy and Subjective Well-Being: A Meta-Analysis of Studies in the US and East Asia

Self-determination theory proposes that human beings have universal basic psychological needs for autonomy, competence, and relatedness, which when satisfied lead to well-being. The current meta-analysis synthesized the correlations between the need for autonomy and subjective well-being. More specifically, because some researchers have questioned the role of autonomy in well-being in non-Western cultures, our meta-analysis focused on the results reported from studies conducted in the United States (US, a typical individualist culture) and East Asian countries (typical collectivist cultures). Random-effects analyses using 36 independent samples (22 from the US and 14 from East Asian samples including China and Japan) totaling 12,906 participants showed a moderate correlation (r = .46, p < .001) between autonomy and subjective well-being. The difference between correlations for studies conducted in the East and West was not significant (Δr = .05, p > .05). Overall, this study lends support to self-determination theory’s proposition that autonomy is a universal psychological need and provides suggestions for cultural practices and policies.

Incidental memory in dogs (Canis familiaris): adaptive behavioral solution at an unexpected memory test

Memory processing in nonhuman animals has been typically tested in situations where the animals are repeatedly trained to retrieve their memory trace, such as delayed matching to sample, serial probe recognition, etc. In contrast, how they utilize incidentally formed memory traces is not well investigated except in rodents. We examined whether domestic dogs could solve an unexpected test based on a single past experience. In Experiment 1, leashed dogs were led to 4 open, baited containers and allowed to eat from 2 of them (Exposure phase). After a walk outside for more than 10?min, during which time the containers were replaced with new identical ones, the dogs were unexpectedly returned to the site and unleashed for free exploration (test phase). Eleven out of 12 dogs first visited one of the containers from which they had not eaten. In Experiment 2, two containers had food in them, one had a nonedible object, and the last one was empty. Dogs visited all 4 containers and were allowed to eat one of the food rewards in the Exposure phase. In the test phase, unleashed dogs first visited the previously baited container from which they had not eaten significantly more often than chance. These results demonstrate that in an unexpected, test dogs may retrieve “what” and “where” information about seen (now invisible) items from incidental memory formed during a single past experience.     

Behavioral orientations and peer-contact patterns of relationally aggressive girls

The present study was designed to assess the behavioral orientations and peer-contact patterns of relationally aggressive girls. Based on teachers' assessments of relational aggression, 16 preschool girls were assigned to either a relationally aggressive group or a nonaggressive group and then observed in a free play setting. Several aspects of their interactive behaviors, e.g., cooperative play and social conversation, and noninteractive behaviors, e.g., solitary play and transition, were observed. Analysis indicated the relationally aggressive group spent more time engaged in social conversation and transition and less time in cooperative play than did the nonaggressive group. Further, findings indicated that the relationally aggressive group spent more time with one particular peer than did the nonaggressive group.
