An experimental approach to the design of cartographic symbols

Graphic designers and an experimental psychologist worked together to improve the design of two map symbols which are frequently confused: the symbols for cuttings and embankments on topographic maps. The problem was analysed in terms of the function of the symbols and their likely cognitive representations. Tests were developed to evaluate alternative designs, including an intervisibility task which requirred users to visualize the landform from the symbols viewed in the context of a map. Tests were given to schoolchildren and to experienced map users in order to compare the standard symbols with five alternative designs. Children's performance was strongly affected by the symbols they used, but experienced users were much less affected. After some refinement of the symbols a further experiment demonstrated the superiority of a number of alternative designs over the existing symbols on a range of test: scores were almost double on the intervisibility task. The paper makes recommendations to cartographers and argues for greater consideration of the inexperienced map user in the design process.     

Are Cognitive,Affective, and Eudaimonic Dimensions of Subjective Well-Being Differently Related to Consumption? Evidence from Japan

In this study, we investigate the relationship between consumption and subjective well-being (SWB). There is clear evidence in the literature that the income–SWB relationship depends on the SWB measure, but the reasons are not fully clear yet; however, the main reason may be related to consumption because most income is used for that. This study is the first to examine directly whether the consumption–SWB relationship differs between affective, cognitive, and eudaimonic SWB measures. We adopt the following four SWB indices: life satisfaction, the Cantril ladder, affect balance, and eudaimonia. In addition, on the consumption side, we consider both material and relational consumption. Nonparametric analysis of our uniquely collected survey results in Japan suggests that total consumption contributes to cognitive measures of SWB and eudaimonia, while there is a certain threshold for affective measures. However, once material versus relational consumption is considered in total consumption, we find that relational consumption contributes to any SWB measure without clear upper bounds, while material consumption contributes to all SWB measures only to certain thresholds. Our results also show that the marginal effects of total consumption, material consumption, and relational consumption on cognitive measures of SWB and eudaimonia are greater than on affective measures. In addition, our results show that the marginal effects of relational consumption tend to be greater than those of material consumption for all SWB indices. Based on the findings, we expect relational consumption to be key for improving well-being.

Theorizing the Temporal Aspect of Ikigai or Life Worth Living among Japanese University Students: a Mixed-Methods Approach

Although cross-cultural and non-Western studies have advanced our knowledge on well-being, many studies have adopted English words including ‘happiness’ as their guiding concepts, which may have limited and biased their insight. The current study is part of a larger mixed-methods project that theorizes how Japanese university students pursue ikigai or a life worth living. The first qualitative study, based on 27 photo-elicitation interviews, generated a grounded theory of houkousei, or life directionality. Our qualitative findings suggested that when students formed explicit associations among the past, present, and future, they gained strong ikigai feelings. These associations were developed either cognitively by mentally associating existing present experiences with the past or future, or behaviourally by strategically choosing current experiences more pertinent to the past or future than alternatives. These actions resulted in two subjective states: life legacy and life momentum. Life legacy was the perception that one’s past had meaningfully contributed to his or her present experiences, life, and self. Life momentum meant the belief that one’s present experiences were helping him or her achieve the desired future. Lastly, having defining past experiences and setting clear goals both facilitated the associative actions. To further validate this theory, we collected online survey data from a national sample of 672 Japanese students. Our quantitative results, based on partial least squares structural equation modelling (PLS-SEM), largely supported our theoretical model. Our findings are discussed in light of the ikigai and eudaimonic well-being literatures.

     

The translation and validation of the Mini‐K scale in Japanese

The purpose of this study was to validate the 20‐item Mini‐K scale, which is the short form of the Arizona Life History Battery, as translated into Japanese. Two samples of Japanese adults (N = 2000; 50.0% men; Mage = 40.9 for the first survey; N = 400; 50.0% men; Mage = 42.2 for the second survey) completed a web‐based questionnaire, including the Japanese translation of the Mini‐K. The results showed that the psychometric properties of the Japanese Mini‐K scale were comparable to those of the original English version. The scale had good reliability based on Cronbach's α and McDonald's ω. Convergent validity was demonstrated by the correlation between the Mini‐K scores and life history indicators. In addition, the Mini‐K score was related to both personality and psychosomatic health. The translated scale provides a valid and reliable instrument in Japanese that measures human life‐history strategy.     

Social Affordances and the Possibility of Ecological Linguistics

This paper includes an effort to extend the notion of affordance from a philosophical point of view the importance of ecological approach for social psychology, ethics, and linguistics. Affordances are not always merely physical but also interpersonal and social. I will conceptualize affordance in general and social affordance in particular, and will elucidate the relation between intentional action and affordances, and that between affordances and free will. I will also focus on the relation between social institution and affordance. An extended theory of affordances can provide a way to analyze in concrete ways how social institution works as an implicit background of interpersonal interactions. Ecological approach considers social institution as the producer and maintainer of affordances. Social institutions construct the niches for human beings. Finally, I will argue the possibility of the ecological linguistics. Language is a social institution. The system of signs is the way to articulate and differentiate interpersonal affordances. Language acquires its meaning, i.e. communicative power in the interpersonal interactions, and interpersonal interactions, in turn, develop and are elaborated through the usage of signs. Communication is seen as never aimed to transmit inner ideas to others, but to guide and adjust the behaviors of others thorough articulating the affordance of responsible-ness.     

Prospective cohort study of stress, life satisfaction, self-rated health, insomnia, and suicide death in Japan

The association between many psychosocial factors and risk of suicide was examined. A cohort was conducted over 14 years of follow up among the general population (15,597 people) in Japan. A baseline survey of psychosocial characteristics was conducted by self-administrated questionnaire. The relative risks of occasional emotional stress, difficulty maintaining sleep, and reporting unhealthy as their self-rated health are 3.2 (95% CI: 1.3, 7.6), 2.4 (95% CI: 1.3, 4.3) and 2.6 (95% CI: 1.1, 6.2), respectively. The importance of these observations lie in its potential for improving physician and public awareness of psychosocial factors as an early indication of mental health morbidity.     

Mapping of interneurons that contribute to food aversive conditioning in the slug brain

To determine the distribution of neurons that contribute to memory formation induced by odor-taste associative conditioning in the slug's brain, we examined neuronal activity of the central nervous system of the slug Limax marginatus using a fluorescent activity marker [Lucifer yellow (LY)]. When LY was injected into the body cavity just after the conditioning, many of the procerebral (PC) interneurons were labeled. The PC lobe was considered to play important roles in the olfaction of the slug, because the olfactory afferent fibers from both the inferior and the superior tentacular noses innervate it. Such strong dye-uptake activity of PC interneurons was not observed when LY was injected just after unpaired control treatment. Thus, it was suggested that enhancement of dye-uptake activity upon conditioning was caused by the association of a conditioning stimulus (CS) with an unconditioned stimulus (UCS). The distribution patterns of PC interneurons that were labeled by LY after conditioning showed a characteristic feature: They usually formed a belt-shaped cluster parallel to the dorsoventral axis. This feature of the distribution was maintained when different odors were used as a CS. Furthermore, the number of the clusters reflected the number of CS odors but not the number of conditioning sessions. From these observations, we considered that enhancement of the neural activity involving dye uptake in each belt-shaped cluster contributed to formation of each odor memory.
