Evaluating gene x psychological risk factor effects in the pathogenesis of anxiety: a new model approach

The present study evaluated the singular and interactive effects of a functional polymorphism (variation) in the serotonin transporter (5-HTT) gene and a psychological trait (anxiety sensitivity [AS], i.e., fear of arousal symptoms) in predicting subjective and physiological responses to a 35% carbon dioxide (CO2) challenge in a community sample (N = 72). Genotypes were divided into 2 groups in accord with prior research. Findings were partially supportive of the hypothesized risk model. These indicated that the Group L genotype (homozygous for the 1 allele), compared with the Group S genotype (homozygous for the s allele plus heterozygous individuals), predicted greater fearful response to the biological challenge. There was also an AS x Genotype interaction predicting heart rate variability (HRV) in response to the CO2, suggesting that high AS plus Group L status predicts decreased HRV.     

The role of inhibition in the regulation of sequential action

We investigated the regulation of sequential action using a new paradigm. Participants learned a sequence of seven stimulus categories and then monitored for them during successive displays. All displays were instances of these categories, presented in pseudorandom order. On each trial, participants monitored for an instance of Category 1, pressed a key on a computer keyboard, then monitored for an instance of Category 2, pressed a key on the keyboard, and so on for all seven categories. Thus, a perfect trial contained exactly seven responses. Intrusion errors were classified as a function of ordinal distance from the current serial position ( n ). Fewer intrusion errors were made at near serial positions than at far ones, suggesting a gradient of lateral inhibition. In addition, more intrusions were made on n + 1 categories than n − 1 categories, suggesting greater availability of intended than completed goals. In accord with current models of sequential action, the results indicate lateral and self-inhibition as important mechanisms in regulation of sequential action.     

科学主义的尴尬与中医学的多向度发展

近５０年的中医现代化研究暴露了科学主义试图消解其他向度存在的独尊倾向,而经络实质研究、证客观化研究等方面的失败,宣告了科学主义并不是解决中医学所有问题的灵丹妙药。科学主义所遇到的这种尴尬局面表明,中医学应该有多种向度的发展,除了现代化研究这一模式之外,至少还应当有两种向度的存在,即原有形态的传统中医学体系应继续存在下去,传统中医学在技术上与西医学的结合应当受到鼓励。     

The impact of justice climate and justice orientation on work outcomes: a cross-level multifoci framework

In this article, which takes a person-situation approach, the authors propose and test a cross-level multifoci model of workplace justice. They crossed 3 types of justice (procedural, informational, and interpersonal) with 2 foci (organization and supervisor) and aggregated to the group level to create 6 distinct justice climate variables. They then tested for the effects of these variables on either organization-directed or supervisor-directed commitment, satisfaction, and citizenship behavior. The authors also tested justice orientation as a moderator of these relationships. The results, based on 231 employees constituting 44 work groups representing multiple organizations and occupations, revealed that 4 forms of justice climate (organization-focused procedural and informational justice climate and supervisor-focused procedural and interpersonal justice climate) were significantly related to various work outcomes after controlling for corresponding individual-level justice perceptions. In addition, some moderation effects were found. Implications for organizations and future research are discussed.     

The lexical constituency model: some implications of research on Chinese for general theories of reading

The authors examine the implications of research on Chinese for theories of reading and propose the lexical constituency model as a general framework for word reading across writing systems. Word identities are defined by 3 interlinked constituents (orthographic, phonological, and semantic). The implemented model simulates the time course of graphic, phonological, and semantic priming effects, including immediate graphic facilitation followed by graphic inhibition with simultaneous phonological facilitation, a pattern unique to the Chinese writing system. Pseudocharacter primes produced only facilitation, supporting the model's assumption that lexical thresholds determine phonological and semantic, but not graphic, effects. More generally, both universal reading processes and writing system constraints exist. Although phonology is universal, its activation process depends on how the writing system structures graphic units.

青少年性发展的差异及其对人格发展的影响

研究青少年性发育现状及其对性心理与人格发展的影响。方法：采用统一编制的《中学生性现状调查问卷》及16PF人格问卷,采用分层抽样方法,对江西4所中学的1000名学生进行问卷调查。结果：(1)青少年手淫行为发生率、与异性交往愿望及性冲动等方面均存在性别差异和年级差异;(2)性成熟的青少年的多种人格特征与未成熟的存在显著性差异。结论：青少年性生理发育正常,但在性心理方面很不成熟,对手淫、性冲动和异性交往等方面问题较多,性发展影响青少年人格发展。

Prosody and lemma selection

In three picture-naming experiments, we examined the effect of prosodic context on the synonyms people use to name pictures in Mandarin Chinese. This was done without time pressure. The results showed that when monosyllabic and bisyllabic synonyms (e.g., hen/chicken) were embedded in a context of pictures with either bisyllabic or trisyllabic names, participants gave bisyllabic responses to the synonyms more often than they did in a condition without such a context. The difference was very similar in magnitude in both the bisyllabic and trisyllabic contextual conditions. These results suggest that people are biased toward using synonyms that have numbers of syllables equal or similar to those of the prosodic context. If it is assumed that prosodic effects originate at a stage of processing beyond the lemma level, then this suggests either that multiple phonological forms of synonyms can be activated or that there is feedback from prosodic processing that influences lemma selection.
