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.     

Cross-serial dependencies in dutch: Testing the influence of NP type on processing load

We tested the cross-linguistic generalizability of three models of sentence processing complexity--Lewis (1996), Gibson (1998, 2000), and Gordon (Gordon, Hendrick, & Johnson, 2001; Gordon, Hendrick, & Levine, 2002)--by investigating the on-line processing of cross-serial dependencies in Dutch. The number of subject-verb relations in a clause was manipulated, as well as type of noun phrase (indexical pronouns vs. proper names or full definite NPs). Several of our findings diverged from Gibson's model: Processing difficulty at the verbs was not affected by the use of proper names versus first- and second-person pronouns; an increase at the first verb was seen for full NPs versus pronouns in 3-verb constructions, which was predicted by the Gibson model, but is in contrast to Lewis's model. These findings are best explained within the framework of similarity-based inference models (Gordon et al., 2001; Gordon et al., 2002), according to which the number of similar NPs affects processing difficulty at the point of retrieval, and not specifically their discourse status or syntactic function.     

Masculinity and femininity in middle childhood: Developmental and factor analyses

Developmental differences in children's self-perceptions of masculinity and femininity during the middle childhood period were investigated in English-speaking children from Grades 2–7 (N=517). The majority of participants were Caucasian and from middle socioeconomic families. The multidimensionality of masculinity and femininity was also examined. The Children's Personal Attributes Questionnaire (CPAQ), a standardized self-report instrument, was used to assess masculinity (instrumentality) and femininity (socioemotional expressiveness). Developmental differences were found within a cross-sectional design, with a decrease in feminine responding and an increase in masculine responding. At the item level, however, both boys and girls were relatively selective and limited in the items that had a grade effect. Interestingly, greater symmetry was observed between boys' masculine and feminine scores than between girls' scores. Furthermore, fewer boys had predominantly masculine responding than girls had predominantly feminine responding. Factor analysis provided initial support for the presence of three factors—interpersonal orientation, leadership, and emotionality—which appear to have greater specificity and reflect more distinct subtraits than the original scales of the CPAQ. The results of the present study suggest that meaningful developmental changes occur during the middle childhood period, and that a single summary score for masculinity or femininity ignores variations in gender-typed subtraits and thus raises both scoring and interpretation concerns.     

Development of Japanese version of the long‐term mating orientation scale (LTMO‐J)

The purpose of this study was to validate the 7‐item long‐term mating orientation scale (LTMO) as translated into Japanese. Two samples of Japanese adults (N = 2000; 50.0% male; Mage = 40.9 for the first survey; N = 300; 54.7% male; Mage = 42.4 for the second survey) completed a web‐based questionnaire, including the Japanese translation of the LTMO. The results showed that the psychometric properties of the Japanese LTMO scale were comparable to those of the original English version. The scale had adequate reliability based on Cronbach's α and McDonald's ω. Convergent validity was demonstrated by the correlation between the LTMO scores and related variables: human life history strategies, short‐term sociosexual orientation, attitude to infidelity, romantic attachment style, and so on. The translated scale provides a valid and reliable instrument in Japanese that measures human mating strategy.     

Personality Change from Life Experiences: Moderation Effect of Attachment Security

This study focused on effects of life experiences on change in personality and moderation effects of attachment security on the life experience influences. With a sample of Japanese university students (N = 1,000; 679 female; M = 19.72; SD = 1.26; age range, 18–25 years), the Big Five personality traits were assessed twice. The assessment interval was 20 weeks. Hierarchical linear modeling (HLM) analyses revealed that there were large between‐individual differences in change and stability of the Big Five personality traits, which were accounted for by the amount of daily positive and negative life experiences during the interval period. Moreover, multi‐group HLM analyses indicated that the life experience effects were moderated by participants' attachment security at Time 1. These findings suggest that the accumulation of small daily experiences may work for the personality development of university students and that environmental influences may vary by individual susceptibility to experiences, like attachment security.     

Asymmetrical neural adaptation in lower leg muscles as a consequence of stereotypical motor training

Despite well-authorized facts regarding asymmetrical architectural changes between different limbs after persistent participation in particular motor training, no studies have addressed the neural aspects to the present. The authors undertook the study to elucidate the possibility of neural adaptation on a limb-by-limb basis after repetitive engagement in a particular motor training routine. We investigated lower leg muscles in endurance-trained track runners who have been trained by routinely running on a track in counterclockwise direction on curved paths. Stretch reflex responses in the plantarflexor muscles (soleus [SOL], medial [MG], and lateral head of the gastrocnemius muscle) were evaluated bilaterally with participants sitting at rest. Comparisons were made between homonymous muscles of the right (corresponding to outside leg for track running) and left leg (inside leg, likewise) and with a group of nontrained controls. The result clearly demonstrated that the responses were prominently different between the legs (thus, asymmetrical) in the MG muscles and partially in the SOL muscles in the trained group. In contrast, no such differences were obtained in the nontrained control group. The result demonstrated that neural adaptation took place asymmetrically and that could be attributable to their repetitive engagement in the stereotypical motor task.     

Personality assessment and behavioral prediction at first impression

Research has demonstrated high levels of consensus and self-other agreement for extraversion and conscientiousness. However, the mechanisms whereby these assessments contribute to accuracy in behavioral predictions remain unclear. In this study, two judges rated targets on Big Five personality factors, and predicted their compliance to offer help in response to a fabricated emergency. Whereas one judge interacted directly with the target, the other judge only observed the interaction. There was consensus and self-other agreement on conscientiousness for both judges. Critically, self-reported conscientiousness fully mediated the effect of judged conscientiousness on compliance to offer help, regardless of the nature of the judge-target interaction. These results demonstrate a mechanism whereby judged personality can predict a specific behavioral outcome in initially unacquainted persons.
