Passion for Driving and Aggressive Driving Behavior: A Look at Their Relationship

The purpose of the present research was to investigate the relationship between passion for driving and aggressive driving behavior in 3 studies. Study 1 examined the association between passion and aggressive driving behavior in a sample of undergraduate students. Results showed that an obsessive passion for driving was associated with aggressive driving behavior, while harmonious passion was not. Study 2 replicated these results with an ecologically valid sample of community‐dwelling drivers. Finally, Study 3 replicated the results obtained in Studies 1 and 2 in a laboratory setting using a driving simulator under controlled frustrating driving situations with judges' assessment of aggressive driving behavior. Study 3 also showed that the emotion of anger mediated the obsessive‐passion/aggressive‐driving‐behavior relationship.     

一种对动物学习记忆能力突变筛查的新途

本文详细描述了一种全自动化的行为检测方案。在自然饲养环境/检测环境(24/7)中, 我们测量了小鼠针对两个给食器中获得食物的比例与它们在相应给食器停留时长的比例进行匹配的精确性与准确性。该方案是对传统条件性习得 (trials-to-acquisition) 行为测验设备的改进, 可以检测动物时间间隔能力的精确性与准确性, 对定时目标选择的相关概率的效果, 以及记忆一天中从不同给食器中获得食物次数的精确性与准确性。该压缩系统避免了在整个实验过程中对小鼠的持握操作, 可忽略实验者/技术员的实验操作时间, 而且可以递送小鼠置入实验环境后, 7~9个实验日中全部3组实验流程产生的大量结果。其中, 第一个实验流程为单个24小时周期内完成的时间匹配能力的筛查, 它对动物的时间、空间估计能力的记忆机制进行精确检测。因此, 该系统允许在有限的实验空间、较短的实验周期内, 对大量的实验小鼠进行有可能存在的学习记忆能力缺陷进行大规模筛查。此外, 该系统运行所依赖的软件可以在公共开放平台获得。     

Integrating cross-cultural psychology research methods into ethnic minority psychology

Multicultural psychology has 2 related but often disconnected streams, namely cross-cultural psychology and racial and ethnic minority psychology (Hall & Maramba, 2001). We propose that advances in both fields will be facilitated if there is greater cross-fertilization, especially in methodological approaches given that proponents in both fields are interested in studying and understanding the role and impact of culture on human behavior. To facilitate this cross-fertilization, we present 3 methodological approaches that would be of value in racial and ethnic minority psychology. First, we present an overview of the importance of and the approaches to evaluating and establishing measurement equivalence. Second, we discuss recent advances in the understanding of conceptual equivalence in light of indigenous approaches, cultural manipulation, and multilevel analysis. Third, we present a combined etic-emic approach to cross-cultural personality research as illustrated by the Cross-Cultural Personality Assessment Inventory developed by Fanny Cheung and her colleagues.     

Reflecting on Participatory,Action‐Oriented Research Methods in Community Psychology: Progress,Problems, and Paths Forward

This paper provides a critical reflection on participatory action research (PAR) methods as they pertain to community psychology. Following a brief review of the fundamental aspects of PAR, key developments in the field are examined. These developments include the redefinition of the research enterprise among groups such as Indigenous and consumer/survivor communities, challenges that attend the “project” framing of PAR, academic and practice context challenges, and important domains in which PAR methods need to become more engaged (e.g., social media and disenfranchised youth). Three illustrative case studies of programs of work in the areas of youth homelessness, consumer/survivor engagement, and Indigenous research are provided to illustrate these contemporary challenges and opportunities in the field. The authors make the argument that without an effort to reconsider and redefine PAR, moving away from the stereotypical PAR “project” frame, these methods will continue to be poorly represented and underutilized in community psychology.     

Information Consistency and Perceptual Set: Overcoming the Mental Retardation “Schema”1

Two factors that were thought to promote or inhibit schema-based or stereotypic responding in impression formation were examined in two experiments. Subjects were asked to provide evaluations of artwork supposedly painted by either mentally retarded or nonretarded children. Based on previous research, it was assumed that subjects would expect relatively poor quality artwork from retarded children, which would he consistent with a negative schema that they maintain for this group. It was also predicted that this negative schema would result in cursory examinations and unfavorable evaluations of the retarded artists' artwork, but only when the evaluative conditions were conducive to schematic responding. Specifically, the schema effect was predicted to occur when the artwork was of poor quality and subjects were instructed to provide an overall evaluation of the painting rather than an assessment of its specific characteristics. No derogation was expected when these factors were not present. Results supported these hypotheses. Additional analyses indicated that subjects were conducting a cursory search of the target stimuli when conditions favored schema-based responding.     

New polytypes of long-period stacking ordered structures in a near-equilibrium Mg97Zn1Y2 alloy

By atomic-scale high-angle annular dark-field scanning transmission electron microscopy, the long-period stacking ordered (LPSO) structures in a near-equilibrium Mg₉₇Zn₁Y₂ (at.%) alloy have been characterised. In addition to 18R and 14H, new polytypes of LPSO structures are analysed and determined as 60R, 78R, 26H, 96R, 38H, 40H, 108H and 246R. All of these LPSO structures feature AB′C′A building blocks with two Mg layers and three Mg layers sandwiched between them. The Bravais lattices and space groups of new polytypes of LPSO structures were easily determined via the newly introduced method. A structural relationship between the LPSOs is proposed.     

Resurgence is greater following a return to the training context than remaining in the extinction context

The present study examined whether resurgence of a previously reinforced target response upon removing alternative reinforcement would be greater when (1) returning to the original training context (ABA context changes) versus (2) remaining in the analogue treatment context in which the alternative response was differentially reinforced (ABB context changes). Experiment 1 arranged reinforcement of button pressing with points exchangeable for money in university students. Experiment 2 arranged reinforcement of lever pressing with food for rats. Experiment 3 arranged reinforcement of responses to a touchscreen with small bites of food with children diagnosed with ASD. Overall, resurgence of target responding tended to be greater when returning to the original training context (A) than when remaining in the analogue treatment context (B). These findings suggest context changes with differential reinforcement treatments could exacerbate the recurrence of problem behavior resulting from reductions in treatment integrity through failure to reinforce appropriate behavior.     

Effect of pressure on the mechanical and dynamical stability of NaAlSi

The effects of pressure on the mechanical and dynamical stability of NaAlSi have been fully investigated by first-principles calculations within the generalised gradient approximation (GGA). The obtained results show that the optimised lattice constants, atomic positions and elastic constants at ambient pressure are in good agreement with the available experimental and theoretical data. The lattice constants decrease monotonically with increasing pressure. The elastic constant C₁₁, C₁₂, C₁₃, C₃₃ and C₆₆ increase while C₄₄ decreases with increasing pressure. It is found that NaAlSi is mechanically unstable when the pressure is above 25.97?GPa. The phonon-dispersion curves along several high symmetry lines are obtained. The phonon frequencies at the Z point decrease with increasing pressure and completely soften to zero at 27.52?GPa, further confirming the structural instability of NaAlSi.     

Telling Others to Do What You Believe Is Morally Wrong: The Case of Confucius and Zai Wo

Can it ever be morally justifiable to tell others to do what we ourselves believe is morally wrong to do? The common sense answer is no. It seems that we should never tell others to do something if we think it is morally wrong to do that act. My first goal is to argue that in Analects 17.21, Confucius tells his disciple not to observe a ritual even though Confucius himself believes that it is morally wrong that one does not observe the ritual. My second goal is to argue against the common sense answer and explain how Confucius can be justified in telling his disciple to do what Confucius thought was wrong. The first justification has to do with telling someone to do what is second best when the person cannot do what is morally best. The second justification has to do with the role of a moral advisor.     

EEG microstates during different phases of Transcendental Meditation practice

Two phases of Transcendental Meditation (TM)—transcending and undirected mentation—were compared to each other and to task-free resting using multichannel EEG recorded from 20 TM practitioners. An EEG microstate analysis identified four classes of microstates which were labeled A, B, C and D, based on their similarity to previously published classes. For each class of microstates, mean duration, coverage and occurrence were computed. Resting and transcending differed from undirected mentation with decreased prominence of Class A and increased prominence of Class D microstates. In addition, transcending showed decreased prominence of Class C microstates compared to undirected mentation. Based on previous findings on the functional significance of the microstate classes, the results indicate an increased reference to reality and decreased visualization during resting and transcending compared to undirected mentation. Also, our results indicate decreased saliency of internally generated mentations during transcending compared to undirected mentation reflecting a more detached and less evaluative processing. It is proposed that the continuous cycling through these two phases of meditation during a TM session might facilitate and train the flexible modulation of the parameters of these microstates of these particular classes which are known to be altered in psychiatric disorders. This might promote beneficial stabilizing effects for the practitioner of TM.
