Observing conspecifics scratching induces a contagion of scratching in Japanese monkeys (Macaca fuscata)

Although a large number of studies have examined self-directed behaviors (SDBs) such as scratching and self-grooming as nonverbal leakage of negative emotional arousal in humans, few studies have investigated the informative function of SDBs in nonhuman primates. The present study investigated whether viewing another monkey scratching itself elicited negative arousal from conspecific observers in Japanese monkeys (Macaca fuscata). An experimental situation was created in which the target monkey watched a stranger through a small peephole and the observer monkey(s) watched the target in turn. Scratching spread when conspecific observers watched the target scratching itself while performing monitoring behavior. The author proposes that the possible contagion of scratching by monkeys observing another's scratching may involve transmission of a psychological state, a primitive style of empathy.     

Collaborative Discovery in a Scientific Domain

This study compares Pairs of subjects with Single subjects in a task of discovering scientific laws with the aid of experiments. Subjects solved a molecular genetics task in a computer micro-world (Dunbar, 1993). Pairs were more successful in discovery than Singles and participated more actively in explanatory activities (i.e., entertaining hypotheses and considering alternative ideas and justifications). Explanatory activities were effective for discovery only when the subjects also conducted crucial experiments. Explanatory activities were facilitated when paired subjects made requests of each other for explanation and focused on them. The study extends from individual to collaborative discovery activities the importance to the discovery process of setting goals to find hypotheses and evidence (Dunbar, 1993) and to construct explanations of phenomena and processes encountered in examples (Chi, Bassok, Lewis, & Glaser, 1989).     

Inclusion of additional studies yields different conclusions: Comment on Sedikides, Gaertner, & Vevea (2005), Journal of Personality and Social Psychology

In a Journal of Personality and Social Psychology article, Sedikides, Gaertner and Vevea (2005) presented two meta-analyses that included eight papers to investigate the question of whether people from Eastern cultures self-enhance more for traits that they view to be important compared to those that they view as unimportant. The results supported their hypothesis: Self-enhancement appears to be pancultural. However, this conclusion is severely compromised by six relevant papers that are not included in their meta-analyses. Importantly, all of these six studies contradicted their hypothesis. When complete meta-analyses are conducted which include all of the relevant papers, a very different pattern of results emerges. Eastern and Western cultures do not differ from each other in the pattern of their self-enhancement of independent and interdependent traits. Furthermore, whereas Westerners self-enhanced significantly more for traits that they viewed to be especially important, East Asians did not. Contrary to the Sedikides et al. (2005) suggestion, the existing evidence suggests substantial cross-cultural variation in self-enhancement, with Westerners being far more self-enhancing than Easterners. Reasons for the conflicting pattern of findings across methods and meta-analyses are discussed.     

The Growth of Multidisciplinarity in the Cognitive Science Society

In a case study of the growth of cognitive science, we analyzed the activities of the Cognitive Science Society with a particular emphasis on the multidisciplinary nature of the field. Analyses of departmental affiliations, training back-grounds, research methodology, and paper citations suggest that the journal Cognitive Science and the Annual Meeting of the Cognitive Science Society are dominated by cognitive psychology and computer science, rather than being an equal division among the constituent disciplines of cognitive science. However, at many levels, a growing percentage of work was found to involve a conjunction of multiple disciplines, such that approximately 30–50% of recent work in the Cognitive Science Society is multidisciplinary. In a questionnaire study of cognitive scientists involved in collaborative research, multidisciplinarity was found to shape the research process and affect the factors associated with successful research.     

Threading dislocation with b=c+2a in 4H-SiC as determined by LACBED

The Burgers vectors of the so-called threading screw dislocations (a total of 28 dislocations) in 4H-SiC were determined by large-angle convergent-beam electron diffraction. A new type of TSD, that is, b = c + 2a dislocation, was identified. Thus, all of the four types of TSD predicted by Onda et al. [Phil. Mag. Lett. 93 (2013) p.591] were identified.     

A cultural psychological analysis of cultural change

Life experience appears to be transforming in contemporary societies, with changes taking place in Asia being particularly substantial. There is strong public interest in understanding how these changes affect individual psyches. Scientific understanding of this issue, however, has not kept pace with change. Research findings from Western societies, the USA in particular, provide a model for understanding and predicting patterns of cultural change in Asia. However, the applicability of the model in this region requires critical examination. This article presents an overview of the available evidence in this research field, reviewing available psychological research that examines cultural change in the USA, China, Japan, and Australia. This paper's aim is to stimulate interest in this research area within the community of Asian social psychologists as our Asia‐based insights have much to contribute to the fundamental research question at stake, and the nature of the interplay between a changing social ecology, cultural environment, and participating psyches.     

Origins of a theory of mind

Twenty-two pairs of typically developing toddlers (M = 24.32 months) and their mothers were observed in a play-room solving puzzles during 30 min. The target of the observations was hand-taking gesture. Researchers have thought that this gesture is rare among typically developing children and is more frequent among autistic children. Ten in 22 children showed this gesture in only 30 min. They should know “I can not do it by myself, but my mother can do it.” When we can assume that children know others’ mental mechanism, it might be the origins of a theory of mind.     

Is the Web as good as the lab? Comparable performance from Web and lab in cognitive/perceptual experiments

With the increasing sophistication and ubiquity of the Internet, behavioral research is on the cusp of a revolution that will do for population sampling what the computer did for stimulus control and measurement. It remains a common assumption, however, that data from self-selected Web samples must involve a trade-off between participant numbers and data quality. Concerns about data quality are heightened for performance-based cognitive and perceptual measures, particularly those that are timed or that involve complex stimuli. In experiments run with uncompensated, anonymous participants whose motivation for participation is unknown, reduced conscientiousness or lack of focus could produce results that would be difficult to interpret due to decreased overall performance, increased variability of performance, or increased measurement noise. Here, we addressed the question of data quality across a range of cognitive and perceptual tests. For three key performance metrics??mean performance, performance variance, and internal reliability??the results from self-selected Web samples did not differ systematically from those obtained from traditionally recruited and/or lab-tested samples. These findings demonstrate that collecting data from uncompensated, anonymous, unsupervised, self-selected participants need not reduce data quality, even for demanding cognitive and perceptual experiments.     

Cohort Effects in the Lateral Preference of Japanese People

Handedness data of the Japanese were collected twice with an interval of 20 years, using an identical handedness inventory. In the second cohort, non-right-handers among male and female students numbered 11.5% and 5.9%, respectively. The results showed that the incidence of non-right-handedness among Japanese females has increased from 20 years ago.
