Exploring the Context-Sensitivity of Collective Action Motivations and the Mobilizing Role of Social Media: A Comparative Interview Study With Activists in Germany and Turkey

Western scholarship has underlined the relevance of social identity, perceived efficacy, emotions, and cost–benefit assessments as central catalysts of collective action. Little has been done to understand the context-sensitivity of these catalysts by means of cross-culturally comparative designs. The current study explores their context-sensitivity. It aims to find out whether existing opportunity structures in a democratic, nonrepressive country like Germany produce catalysts of collective action different from those produced in an autocratic, repressive country like Turkey. It also aims to understand the role of social media in mobilizing people in these two contexts. Semistandardized interviews with activists were carried out in both countries (n = 18 in Germany and n = 15 in Turkey) and analyzed by means of a cross-culturally comparative inductive coding procedure including initial and focused coding. Results show that collective action is related to different configurations of collective-action catalysts in the two countries. Solidarity concerns at the face of existential risks are more pronounced in Turkey, whereas political-change concerns are more important in Germany. The role of social media accordingly differs, adhering to the different activist goals. Theoretical implications for the role of context in studying collective action are discussed.     

Moving window generator for reading experiments

An inexpensive PC-based moving window generator with an eye movement recording system is described. The moving window technique, activated by current eye movements, has an advantage over the fixed window technique in measuring the effective visual field size during reading. A variable rectangular window, through which the subject observes the text, is generated on a PC-controlled CRT screen. The system includes a frame buffer memory, an analog-to-digital conversion unit, and an eye movement recording system. The system works well for measuring approximate field size during reading.     

The Concept of Yuko-Datotsu in Kendo: Interpreted from the Aesthetics of Zanshin

As kendo continues to gain in international popularity, there are hopes for its adoption in the Olympic Games as an international competitive event, even while moves to further this aim have not necessarily occurred in Japan or elsewhere. One reason for the efforts to achieve a form of globalization of kendo different from Judo is the attempt to adhere to and preserve the unique concepts kendo, the sport embodies by remaining true to the forms of traditional Japanese culture. This is epitomized by the importance given to zanshin (the combination of posture and fighting spirit after striking), one of the key concepts that constitute yuko-datotsu in kendo. Our purpose in this study is to discuss the intersubjective nature of the decisions regarding the conditions for point-scoring in competitive sports. In particular, we will focus on the aesthetics required for zanshin in kendo, focusing on the theory behind yuko-datotsu (point score), which will also considerably influence its international dissemination. Kendo is characterized from the perspective of western rationalism as an appreciation of form and rules of behavior referred to as formalism and, in this respect, it has unique characteristics differing from those of modern sports that are disseminated internationally. In martial arts, besides refinement and proficiency in the rules of behavior by rigidly adhering to form and rules of behavior and repetition, the aim is to transcend said form and the rules of behavior and embody the spiritual nature dwelling in the background. Kendo should remain traditional path and keep zanshin in the value of point (yuko-datotsu) for its virtue. Kendo has not yet developed into an international competitive sport, but it is in the process of traversing that Geido path as a Do for the purpose of character building through it. Throughout life, one should try to devote oneself to kendo with thought for the value of transcending form and the rules of behaviour, and embodying the spiritual nature of the sport that inheres in its background. That is why one may perceive an evident hesitation or indeed negativity regarding the possible internationalization or development as an Olympic event.     

Examination of the Japanese version of the Fear of COVID-19 Scale among Adults Using Classical Test Theory and Item Response Theory1, 2

Globally, the COVID-19 pandemic has impaired every aspect of life, especially causing much psychological damage—for instance, increasing the risk of suicide. Intense fear and anxiety are considered to play a central role in mental health problems. This study examined the psychological properties of the Japanese version of the Fear of COVID-19 Scale (FCV-19S) using classical test theory (CTT) and item response theory (IRT). Five hundred fifty participants aged 18–69 years and from across Japan completed questionnaires, including the Japanese FCV-19S, the Japanese Depression Anxiety Stress Scales-15 (DASS-15), and the Japanese version of the Kessler 6 (K6). CTT showed that each item of the Japanese FCV-19S had no ceiling and floor effect and was close to the normal distribution, and IRT revealed that each item had an appropriate parameter of discrimination and difficulty. Finally, the Japanese FCV-19S was shown to have an acceptable reliability and moderate good concurrent validity. Consequently, the Japanese FCV-19S has robust psychometric properties and can be useful for early detection of adults impacted by the COVID-19 pandemic.     

“To eat or not to be eaten?” Collective risk-monitoring in groups

The importance of risk-monitoring has been increasing in many key aspects of our modern lives. This paper examines how individuals monitor such risks collectively by extending a behavioral ecological model of animal foraging to human groups. Just as animals must forage for food under predatory risk, humans must divide valuable material and psychological resources between foraging activity and risk-monitoring activity. We predicted that game-theoretic aspects of the group situation complicate such a trade-off decision in resource allocation, eventually yielding a mixed equilibrium in a group. When the equilibrium is reached, only a subset of members engage in the risk-monitoring activity while others free-ride, concentrating mainly on their own foraging activity. Laboratory groups engaging in foraging under moderate risk provided a support to this prediction. When the risk-level was set higher, however, “herding behavior” (conforming to the dominant behavior) interfered with the emergence of equilibrium. Implications for risk management are discussed.     

Is g an entity? A Japanese twin study using syllogisms and intelligence tests

Using a behavioral genetic approach, we examined the validity of the hypothesis concerning the singularity of human general intelligence, the g theory, by analyzing data from two tests: the first consisted of 100 syllogism problems and the second a full-scale intelligence test. The participants were 448 Japanese young adult twins (167 pairs of identical and 53 pairs of fraternal twins). Data were analyzed for their fit to two kinds of multivariate genetic models: a common pathway model, in which a higher-order latent variable, g, was postulated as an entity; and an independent pathway model, in which the higher-order latent variable was not posited. These analyses revealed that the common pathway model which included additive genetic and nonshared environmental factors best accounted for the three distinct mental abilities: syllogistic logical deductive reasoning, verbal, and spatial. Both the substantial g-loading for syllogism-solving, historically recognized as the symbol of human intelligence, and the emergence of g as an entity at an etiological level, that is, at the genetic and environmental factor level, provide further support for the g theory.     

Differences in adrenocortical secretory and gene expression responses to stimulation in vitro by ACTH or prolactin between high- and low-avoidance Hatano rats

Rats of the Hatano high-avoidance (HAA) and low-avoidance (LAA) strains have been genetically selected on the basis of their two-way active avoidance behavior, and have different endocrine responses to stress. The present study focused on the adrenal steroid hormone responses of the Hatano strains and identifies differences in regulation of the adrenal cortex in vitro of HAA and LAA rats. Although incubation with prolactin (PRL) and/or adrenocorticotrophic hormone (ACTH) resulted in a dose-dependent increase of corticosterone and progesterone release by adrenal cells from both HAA and LAA male rats, the responses were markedly increased for adrenal cells from LAA rats as compared with HAA rats. This finding suggested that adrenal glands of HAA rats are less sensitive to PRL and/or ACTH than adrenals from LAA rats. Several possible intra-adrenal regulators were investigated. The basal level of expression of steroidogenic acute regulatory protein (StAR) and the long form of the PRL receptor (PRLR-L) mRNAs was higher in adrenals of LAA rats. ACTH treatment of adrenal cells from HAA rats resulted in statistically significant increases in melanocortin receptor 2 (MC2R) mRNA expression, while neither ACTH nor PRL altered MC2R mRNA expression in adrenal cells of LAA rats. Conversely, the increase in PRLR-L mRNA expression induced by PRL was observed only in adrenal cells from LAA rats. Treatment of adrenal cells with PRL and/or ACTH increased the expression of StAR and CYP11A1 mRNAs for both Hatano strains. However, the induction of StAR mRNA expression was higher in LAA rats, but the CYP11A1 response was lower. These findings indicate that adrenal cells of the LAA strain have higher sensitivity to secretagogues than those of the HAA strain. These results suggest that PRL may also be important in stimulating secretion of adrenal steroid hormones.     

Conditioned taste aversion with sucrose and tactile stimuli in the pond snail Lymnaea stagnalis

A new form of taste aversion conditioning was established in the pond snail Lymnaea stagnalis. An associative memory, lasting 24h, was produced in the pond snail with 20 pairings of 100 mM sucrose as the conditioned stimulus (CS) and mechanical stimulation to the head as the unconditioned stimulus (UCS). Animals exposed to reverse pairings of the CS and UCS failed to learn the association. The learning was characterized by a shift in the response to the UCS from a whole-body withdrawal response to the cessation of feeding behavior.     

An ERP study of sensory mismatch expressions in Japanese

Combinations of different sensory words produce mismatch expressions like smooth color and red touch in contrast to normal expressions like red color and smooth touch. Concerning these sensory mismatch expressions, results of three experiments are reported. Experiment 1 revealed that (i) mismatch expressions were less comprehensible than normal expressions, and that (ii) there were two patterns among mismatch expressions: the high-comprehensible mismatch expression (HighCME, e.g., smooth color) and the low-comprehensible mismatch expression (LowCME, e.g., red touch). Experiment 2 revealed that the mismatch expressions produced a significantly greater N400 amplitude than the normal expressions. Experiment 3 implied that the difference between High/LowCME was reflected in a later latency band or in a topographical difference of N400, although the statistical significance was marginal. It is argued that the processes to integrate linguistic elements (e.g., combining adjectives and nouns) are not homogeneous.
