Consistent and variable practice conditions: effects on relative and absolute timing

The authors conducted the present experiments to resolve the discrepancy between studies in which relative-timing learning has been found to be enhanced by consistent practice conditions and contextual interference experiments in which relative-timing learning has been found to be enhanced more by random practice than by blocked practice. There were 40 participants in Experiment 1 and 48 in Experiment 2. The results of Experiment 1 extended previous findings: The learning of the relative-timing pattern was systematically enhanced by the degree to which the practice conditions promoted movement consistency (constant > blocked > serial > random). Experiment 2 provided evidence that the discrepancy between the relative-timing effects in the 2 groups of studies was a product of the way in which relative-timing goals and feedback were presented. When the feedback was presented as segment times, random practice resulted in generally more stable relative-timing patterns during acquisition than blocked practice did. Thus, in both experiments, the learning of the relative-timing pattern was enhanced by more stable relative-timing conditions during acquisition. Absolute-timing learning, as indexed by the transfer tests, was enhanced by serial or random practice as compared with constant or blocked practice, and was relatively unaffected by feedback conditions directed at the relative-timing pattern. In terms of motor programming theory, those findings are taken as additional evidence for the disassociation of memories supporting generalized motor program (GMP) performance, as indexed by relative timing, and parameter performance, as indexed by absolute timing.

The Significance of Family Structure in Internalizing (Anxious/Depressed) and Externalizing (Aggressive/Delinquent) Problems among Chinese Adolescents

The present pioneering study investigated the differences across various types of family structure among Chinese adolescents with proactive and reactive aggression. It aimed at providing frontline social workers and family therapists with inspirations for designing suitable interventions for adolescents with specific subtypes of aggressive behavior from different family structure backgrounds. After completing an online survey including the Reactive and Proactive Aggression Questionnaire (RPQ) and the subscales of the Child Behavior Checklist – Youth Self-report (CBCL-YSR) on aggressive behavior, delinquent behavior, and anxious/depressed symptom, 520 out of 13,338 Chinese adolescents aged 11 to 18 were randomly selected and stratified based on the types of family structure (intact family, single father family, single mother family, stepfather family, and stepmother family). Expectedly, boys elicited more proactive aggression, delinquent behaviors, and aggressive behaviors than girls. Besides, significant cross-structural differences were found between children from stepmother family, who showed more proactive aggression, anxious/depressed symptoms, aggressive behaviors, and delinquent behaviors, and those from intact family regardless of gender. The interaction effects between gender and family structure were significant for reactive aggression, anxious/depressed behavior, and aggressive behavior. An interaction effect showed boys from stepmother families were more reactively aggressive than those from intact families. In addition, more anxious/depressed symptoms were found in boys from stepmother family than those from intact and single mother families. In conclusion, the impacts of family structure on proactive aggression and delinquent behavior are not gender specific, but the impacts on reactive aggression and anxious/depressed behavior are only specific to boys.

     

Trajectories of Happiness 5 Years Following Medical Discharge for Traumatic Disability: Differences Between Insider and Outsider Perspectives

We studied the predictive impact of proxy “outsider” reports, injury type, and functional independence on trajectories of happiness over the first 5 years following medical treatment for a traumatic spinal cord injury, brain injury, severe burns or inter-articular fractures (total N = 1,271). It was anticipated that lower functional independence and outsider status would predict lower happiness trajectories, with injury type having little effect over time. A measure of functional impairment and the life satisfaction index containing the items that assessed happiness were administered 12, 24, 48, and 60 months post-discharge. Trajectory modeling revealed that lower functional independence significantly predicted lower happiness, regardless of injury type. Outsider reports predicted significantly higher happiness scores than the insiders reported themselves. These differences persisted across time and injury type. Additional analyses found that insider/outsider status accounted for one percent of the variance in happiness scores and functional independence accounted for twenty percent of the variance. Moreover, for all injury groups, there was no evidence for changes in happiness trajectories over time. Outsider accounts differ significantly from insider estimations of variables of positive adjustment accounts but explain little variation in the reports of happiness overall and still have practical and clinical value as secondary sources of information about positive emotional experiences, particularly when reports from the “insider” are not possible.     

The Problem with Having Two Watches: Assessment of Fit When RMSEA and CFI Disagree

The root mean square error of approximation (RMSEA) and the comparative fit index (CFI) are two widely applied indices to assess fit of structural equation models. Because these two indices are viewed positively by researchers, one might presume that their values would yield comparable qualitative assessments of model fit for any data set. When RMSEA and CFI offer different evaluations of model fit, we argue that researchers are likely to be confused and potentially make incorrect research conclusions. We derive the necessary as well as the sufficient conditions for inconsistent interpretations of these indices. We also study inconsistency in results for RMSEA and CFI at the sample level. Rather than indicating that the model is misspecified in a particular manner or that there are any flaws in the data, the two indices can disagree because (a) they evaluate, by design, the magnitude of the model's fit function value from different perspectives; (b) the cutoff values for these indices are arbitrary; and (c) the meaning of “good” fit and its relationship with fit indices are not well understood. In the context of inconsistent judgments of fit using RMSEA and CFI, we discuss the implications of using cutoff values to evaluate model fit in practice and to design SEM studies.     

The embodiment of beauty: Evidence from viewing Chinese concrete words and pictographs

How is beauty embodied? According to the viewpoint of embodied cognition, the aesthetic processing of words or pictographs has roots in their referential archetypes. Four experiments tested whether the beauty of referential archetypes was routinely activated during the explicit and implicit aesthetic evaluations of the font structures of concrete Chinese words and pictographs in congruent or incongruent font colour. Results showed font structures of simplified Chinese words and pictographs were judged to be more beautiful when they referred to beautiful archetypes; and this pattern was reversed when they referred to ugly archetypes. Moreover, judgement was facilitated when font colour was congruent for Chinese words and pictographs referred to beautiful archetypes. For those referred to ugly archetypes, judgement was inhibited in congruent font colour but facilitated in incongruent font colour, suggesting aesthetic perceptions of the font structures of Chinese words and pictographs were derived from their referential natural objects. The spontaneous generation hypothesis of beauty is proposed to account for these findings.     

Communication and crying in newborns

Few studies have analysed newborns’ crying behaviour in relation to the communicative context. In the present study, duration, latency and dysphony of newborns’ cry were analysed in three different communicative conditions: absent, continuous and discontinuous tactile communication. Thirty newborns were randomly assigned to three tactile communicative procedures. Subsequently they were presented with two visual stimuli, face (social-stimulus) and square (non-social-stimulus). The study showed that newborns cried only during visual stimuli presentation both in absent and continuous communication conditions. Newborns with absent communication cried more, with shorter latency and more dysphony than newborns with continuous communication. No significant differences were found in duration, latency and dysphony of newborns’ cry between the two stimuli. Newborns in the discontinuous communicative condition did not cry either during tactile communication or during visual stimuli presentation. Different communicative contexts affected the newborns’ crying behaviour during stimuli presentation. Different interpretations are discussed here in order to explain the results.     

圣贤之后的人生追寻:冯友兰《新世训》的伦理学意义

Feng Youlan’s Xin Shixun 新世训 (New Treatise on the Way of Life) written in the late 1930s differed from traditional moral teachings because it focused on nonmoral life lessons and how to “virtuously” pursue success. It advanced an interpretation of traditional virtues as life lessons for young people, so that these virtues could transform an individual life in modern society. Thereby the morals of ancient sages could transfer to the modern, individual, and morality. The problem is just how the ideals of traditional Chinese culture have adjusted themselves to modern society. Following the phrase “after-virtue”, this effort can be called a pursuit of “after-sage”.

News Blogging in Cross-Cultural Contexts: A Report on the Struggle for Voice

To assess some of the ways that blogs appear to be affecting news reporting and consumption as well as some giving a sense as to their implications for social stability, this paper presents a preliminary analysis of views and comments by bloggers in Asian countries. Data on this topic was gathered by e-mail interviews of Asian bloggers as well as by collecting writings and data from relevant websites. Analysis suggests that, in many societies in Asia and elsewhere, bloggers have become an important source of news outside of but also alongside of traditional mainstream media. A trend is observed that information and communication technologies are reconfiguring the traditional balance between the creators and consumers of news and the journalistic reporting profession. Internet blogs and mobile phones, among other technologies, have made new information and perspectives available concerning local events; they have also added important and often oppositional interpretations of the significance and meaning of those events. Thus, on both professional and economic grounds, the New Media are reducing the relative prominence of traditional news outlets as well as stature of professional journalists.
