Sense of community improves community participation in Chinese residential communities: The mediating role of sense of community responsibility and prosocial tendencies

Community participation is essential for community development and enhancing quality of life. Several studies have focused on the relationship between sense of community (SOC) and community participation in organizational settings. Guided by the community experiences framework, this study aims to examine how a SOC improves community participation in Chinese residential communities. Moreover, the study aims to assess the mediating role of SOC responsibility (SOC-R) and prosocial tendencies in that relationship. A sample of 433 residents completed questionnaires regarding their SOC, sense of community responsibility, prosocial tendencies, and community participation. Using a linear regression model, we found that a SOC can positively predict the level of community participation. Mediation effect analysis revealed that a SOC-R mediated the relationship between SOC and community participation. In addition, prosocial tendencies mediated the association between the SOC and community participation. Using multiple mediation analysis, we found that SOC-R and prosocial tendencies mediated the link between a SOC and community participation in a sequential manner. The findings of this study complement existing research by uncovering the mechanism underlying the relationship between a SOC and community participation.

Reasoning about Sensing Actions in Domains with Multi-Valued Fluents

In this paper, we discuss the weakness of current action languages for sensing actions with respect to modeling domains with multi-valued fluents. To address this problem, we propose a language with sensing actions and multi-valued fluents, called AM_K, provide a transition function based semantics for the language, and demonstrate its use through several examples from the literature. We then define the entailment relationship between action theories and queries in AM_K, denoted by ⊧AM_K, and discuss some properties about AM_K.     

Brief maternal interaction increases number, amplitude, and bout size of isolation-induced ultrasonic vocalizations in infant rats (Rattus norvegicus)

The number, amplitude, duration, and bout structure of isolation-induced ultrasonic vocalization (USV) of infant rats (Rattus norvegicus) were measured on postnatal Day 10. Measurements were made before and after a brief, 1-min, active interaction with their mother or before and after a "pick-up" control procedure. Consistent with prior studies, the number of USVs emitted was significantly increased in the period following the maternal reunion but not after the control procedure. The average amplitude of USVs was also greater following maternal reunion. Finally, analyses characterizing the bout structure of USV production indicated that the average bout size (i.e. number of USVs/bout) was increased severalfold following the reunion with the mother, accounting for the greater rate of USV production during the second isolation period.     

The impact of associative strength on performance in goal pursuit

The present research explored the hypothesis that strengthened attainment means–goal association leads to enhanced performance in goal pursuit. We hypothesize that because of the instrumental nature of means–goal association, strengthened associative strength leads to greater instrumentality expectancy of the means, which elicits greater motivation in the pursuit and hence better actual performance. We demonstrated in four studies that when the means is believed to facilitate goal attainment, a strong (vs. weak) means–goal association leads to greater performance in goal pursuit. Conversely, when the means is perceived to undermine goal attainment, a strong (vs. weak) association results in worse performance in goal pursuit.

Beware of friends: The cultural psychology of relational mobility and cautious intimacy

Previous research has contrasted patterns of cautious or prevention‐oriented relationality in various West African settings with patterns of growth or promotion‐oriented relationality in many North American settings. The present research draws upon the concept of relational mobility to test the hypothesis that different patterns of relationality have their source in respective affordances for embedded interdependence or abstracted independence. Study 1 investigated the relationship between cautious intimacy and perception of relational mobility among a sample of Hong Kong students. Study 2 compared students in Hong Kong and North American settings to test whether differences in perception of relational mobility mediated the hypothesized differences in caution about friends. Study 3 used an experimental manipulation among a sample of Hong Kong students to test the hypothesis that increased perception of relational mobility reduces caution about friends. Results reveal broad support for the hypotheses. Whether as a measured variable or as an experimental treatment, the perception of relational mobility was negatively related to caution about friends. Moreover, this relationship mediated hypothesized cross‐national differences in caution about friendship. A discussion of the results considers intersections of cultural and ecological approaches to psychology and implications for theoretical conceptions of interdependence.     

Comparison of brain mechanisms underlying the processing of Chinese characters and pseudo-characters: an event-related potential study

Most Chinese characters are composed of a semantic radical on the left and a phonetic radical on the right. The semantic radical provides the semantic information; the phonetic radical provides information concerning the pronunciation of the whole character. The pseudo‐characters in the study consisted of different sub‐lexical parts of real Chinese characters and consequently they also had the semantic radical and the phonetic radical. But they were not readable and had no actual meaning. In order to investigate the spatiotemporal cortical activation patterns underlying the orthographic, phonological and semantic processing of Chinese characters, we used event‐related brain potentials (ERPs) to explore the processing of Chinese characters and pseudo‐characters when 14 healthy Chinese college students viewed the characters passively. Results showed that both Chinese characters and pseudo‐characters elicited an evident negative potential peaking around 120 ms (N120), which appeared to reflect initial orthographic distinction and evaluation. Then, Chinese pseudo‐characters elicited a more positive ERP deflection (P220) than did Chinese characters 200–250 ms after onset of the stimuli. It was similar to the recognition potential (RP) and might reflect the integration processes of phonological and semantic processing on the basis of early orthographic information. Dipole source analysis of the difference wave (pseudo‐characters minus characters) indicated that a generator localized in the left temporal‐occipital junction contributed to this effect, which was possibly related to phonological and perceptual–semantic information integration. Between 350–450 ms, a greater negativity (N360) in pseudo‐characters as compared to characters was found over midline fronto‐central scalp regions. Dipole analysis localized the generator of N360 in the right parahippocampal cortex. Therefore, the N360 might be an N400 component and reflect the higher‐level semantic activation on the basis of orthographic, phonological and perceptual–semantic processing.
