Evans双重加工理论的发展过程简要述评

英国心理学家Evans在对他所提出的有关人类思维的"双重加工理论"进行30多年的研究过程中,其理论的名称和内涵等方面都有个不断发展的过程。就该理论的名称而言,通常称为双重加工理论,同时他还提出了双因素理论。主要与"双重加工理论"这一名称相联系的几组概念包括:类型1—类型2,启发式—分析式,不可明言加工—外显思维加工,系统1—系统2;主要与"双因素理论"这一名称相关联的两组概念是:理性1—理性2,逻辑加工—非逻辑加工。最近,他又以"两种心灵假设"为名概括他的理论内容。该文对双重加工理论在名称及相应的内涵的历史发展过程作了较为详尽的评述。     

Hold the future,let the past go: Attention prefers the features of future targets

Previous studies have shown that attention can be captured by task-irrelevant distractors under the guidance of attentional control settings. However, it is unknown whether people can establish an attentional control setting (ACS) for a sequence of distinct events. The present study tested that question by asking observers to expect a sequence of two colored targets in a specific order. The results show that irrelevant distractors that matched either the color of the first expected target or that of the second target captured attention. Thus observers are unable to temporarily suppress the color of the future target in their ACS. However, the temporal order of targets is still useful for guiding attention: Observers were able to abandon the color of the first target and maintain an ACS for the second one as long as there was a sufficient time interval between the two targets.     

SHALL WE DANCE? MUSIC AS A PORT OF ENTRANCE TO MATERNAL–INFANT INTERSUBJECTIVITY IN A CONTEXT OF POSTNATAL DEPRESSION

The present study introduces the concept of a mother–infant group therapy that makes use of music, singing, and moving to establish maternal–infant intersubjectivity. It was conducted in a residential mother–baby unit for mothers with postnatal depression and their infants over a 5‐week period. Maternal–infant intersubjectivity of four dyads in relation to the group dynamics were microanalyzed for Sessions 1 and 5. We made within‐session (i.e., beginning–middle–end) and between‐session (Session 1 vs. Session 5) comparisons for the number of intersubjectivity moments (ISMs), total time of intersubjectivity (IST), and the mean duration of ISMs on a dyadic (i.e., own mother/infant involved) and a nondyadic level (i.e., own mother/infant not involved). In addition, three ISM levels (degree of group contribution) were distinguished. The results indicated a significant increase of ISMs/IST from Session 1 to Session 5. Within‐session analyses showed that ISMs/IST significantly decreased through Session 1 and remained stable throughout Session 5. Intersubjectivity occurred mainly on ISM Level 1 during Session 1 and on ISM Level 3 during Session 5, suggesting increased dyadic autonomy and self‐efficacy. The results are discussed in relation to the musical characteristics of mother–infant dyads, music improvisation techniques, group processes, and intersubjective development.     

On Pretabular Logics in NExtK4 (Part I)

This paper partly answers the question “what a frame may be exactly like when it characterizes a pretabular logic in NExtK4”. We prove the pretabularity crieria for the logics of finite depth in NExtK4. In order to find out the criteria, we create two useful concepts—“pointwise reduction” and “invariance under pointwise reductions”, which will remain important in dealing with the case of infinite depth.     

Intrinsic motivation a key enabler of African managers’ cultural intelligence

This study sought to determine manager's intrinsic motivation to engage multiculturally in the workplace as the managers varied by demographic background. Participants were a convenience sample of managers on supervisory level, middle level and senior level (n=550; Male 54.9%; Black ethnicity 64.4%). They completed the Motivational Scale of the Managerial Cultural Intelligence Measure. The data were analysed by means analysis of variance procedures to determine workforce diversity ability by managerial level and other demographics. The results showed a managerial level effect in that senior managers were significantly more motivated to get information about other cultures in the work group compared to middle managers and supervisors. Supervisors were significantly more willing to change their views of other cultures with learning as compared to senior managers and middle managers. Generally, managers with a shorter employment history are more motivated to engage with multi-cultural groups compared to those with a longer service history. Managers’ motivation to engage multi-culturally would enhance their competence in working with a diverse workforce and thereby embracing true democracy in the workplace.     

论基础公理与反基础公理

"循环并不可恶"。本文在此基础上讨论基础公理和反基础公理。首先指出基础公理原本就是一条有争议的公理;第二,说明基础公理的局限性;第三,详细论述反基础公理家族中的三个成员,并给出它们两两不相容的一个证明;第四,分析反基础公理导致集合论域在V=WF上不断扩张的方法,并指出这种扩张的方法与数系扩张的方法相同;最后结论:良基集合理论(ZFC)与非良基集合理论(ZFC~-+AFA(或者ZFC和ZFC~-+FAFA或者ZFC和ZFC~-+SAFA))之间的关系类似于欧几里得几何学与非欧几何学之间的关系。     

Effect of electron concentration on the Laves phase stability of NbCr2–Ni produced by powder metallurgy

The powder metallurgy technology of mechanical alloying followed by hot-pressing consolidation has been used to obtain NbCr₂–Ni Laves phases. High-purity Nb, Cr, and Ni crystalline powders were milled for periods up to 35 h. These powders were vacuum sintered at 1250°C for 0.5 h under 45 MPa. The phase transformations of NbCr₂–Ni Laves phases have been investigated by X-ray diffraction. The grain size decreases and the microstrain increases with increased Ni content. Different phase transformations were observed from NbCr₂–Ni intermetallics. It is found that the electron concentration and phase stability correlation is obeyed in the Nb–Cr–Ni systems. However, the electron concentration corresponding to the C15/C14 phase transition is found to move to a higher value (i.e. 6.103) than the predicted one (i.e. 5.88) in the literature.     

Culture,social class,and independence–interdependence: The case of Chinese adolescents

Social class demarcates sociocultural environments differing in the relative abundance and scarcity of resources, which in turn differentially afford independent and interdependent psychological processes. The relationships between social class and psychological processes are well documented in Western populations but less so elsewhere. Examining such a relationship is particularly important in China, with its unique historical and sociocultural issues surrounding social class. This research examined the relationship between social class and independence–interdependence among Chinese adolescents (N = 1184). Findings were consistent across a diverse array of psychological processes implicated by independence–interdependence: Participants with well‐educated parents experienced more socially disengaging emotions and a higher level of self‐esteem, and were more inclined toward dispositional attribution and focused attention, compared to participants with less well‐educated parents. These findings highlight the cross‐cultural commonality in the relationship between social class and independence–interdependence.     

Visual field asymmetry in attentional capture

The present study examined the spatial distribution of involuntary attentional capture over the two visual hemi-fields. A new experiment, and an analysis of three previous experiments showed that distractors in the left visual field that matched a sought-for target in color produced a much larger capture effect than identical distractors in the right visual field, revealing a visual field asymmetry in color-based contingent capture. On the other hand, abrupt onsets in the two hemi-fields did not differ in the magnitude of their capture effect, indicating a symmetric distribution of onset capture. The different spatial patterns for contingent capture and onset capture reveal differences between the two types of attentional capture, possibly indicating differences in the underlying brain mechanisms.
