风险对两类跨期选择的影响：一项ERP研究

该研究利用ERP技术,采用伴随风险的跨期选择任务比较了两类跨期选择（立即vs.延迟、延迟vs.延迟）,并探究了风险（零风险、低风险、高风险）对两者跨期选择影响的神经动力学机制。ERP结果显示,对于立即vs.延迟和延迟vs.延迟,在N2和N400上前者大于后者,在LPC上后者大于前者;风险对两者在时程上的影响趋于一致。因此,其加工可能是先对奖赏在风险维度上进行折扣,再与延迟时间进行整合形成奖赏预期,而后做出选择。

The counselor perspective on the use of directives in counseling in China: Are directives different in China as in the United States?

Eight Chinese counselors were interviewed about their use of directives in counseling. They typically believed that directives can be beneficial in counseling Chinese clients. They used directives to extend the influence of counseling beyond sessions, meet client needs and expectations, and fit their own personality and orientation. In terms of conditions that need to be met for directives to be helpful, they identified client factors such as readiness, communication styles, past experience, and insight; the counselor factor of ability to communicate directives; and the therapeutic relationship. They emphasized the importance of clients acquiring a new perspective as a result of directives. Cultural factors in using directives are discussed.     

词汇飞跃的本质:命名洞察力的实证研究

通过个案跟踪和控制实验探讨了词汇飞跃的本质。研究结果表明命名洞察力具有现实性,且词汇飞跃与命名洞察力的出现紧密相关,这在一定程度上解释了儿童词汇量快速增长的原因。命名洞察力的获得促进了词汇的快速增长,标志着儿童建立起词汇与指称之间的匹配关系。词汇飞跃之后,儿童很快建立起词语间的符号关系,并最终促进了儿童语法的发展。基于此实证结果,本研究还建构了诠释词汇飞跃本质的理论模型。     

Comparing Latent Means Without Mean Structure Models: A Projection-Based Approach

The conventional setup for multi-group structural equation modeling requires a stringent condition of cross-group equality of intercepts before mean comparison with latent variables can be conducted. This article proposes a new setup that allows mean comparison without the need to estimate any mean structural model. By projecting the observed sample means onto the space of the common scores and the space orthogonal to that of the common scores, the new setup allows identifying and estimating the means of the common and specific factors, although, without replicate measures, variances of specific factors cannot be distinguished from those of measurement errors. Under the new setup, testing cross-group mean differences of the common scores is done independently from that of the specific factors. Such independent testing eliminates the requirement for cross-group equality of intercepts by the conventional setup in order to test cross-group equality of means of latent variables using chi-square-difference statistics. The most appealing piece of the new setup is a validity index for mean differences, defined as the percentage of the sum of the squared observed mean differences that is due to that of the mean differences of the common scores. By analyzing real data with two groups, the new setup is shown to offer more information than what is obtained under the conventional setup.     

The differential outcomes procedure can overcome self-bias in perceptual matching

There are biases in perceptual matching between shapes and labels referring to familiar others, compared with when the labels refer to unfamiliar people. We assessed whether these biases could be affected by differential feedback (using the differential outcomes procedure [DOP]) compared with when feedback is provided using a nondifferential outcomes procedure (NOP). Participants formed associations between simple geometric shapes and labels referring to people the participant did or did not know (self, best friend, other). Subsequently, the task was to match a label to one of two shapes shown on a trial. When feedback for correct responses was given following the NOP condition, matches were faster to known people (self and friend) compared with those to an unknown person (stranger). However, this advantage for known personal relations was eliminated when participants were given feedback for correct responses following the DOP condition. The data are consistent with prior work showing that the DOP can facilitate the learning of taxing associations (for the stranger stimuli relative to the familiar self and friend stimuli). In addition, the results suggest that the facilitated perceptual matching for stimuli associated to individuals known personally may reflect better individuation of the association between the shape stimulus and the label, a process enhanced by using a DOP for associations with unfamiliar people.     

The relationship between impulsivity and suicide among rural youths aged 15–35 years: a case–control psychological autopsy study

In China, the gender ratio of suicide rates did not match the Western patterns, which was higher for females than males. However, the rural men were at relatively high risk of suicide in Liaoning province. Impulsivity was an important factor of suicide behaviors, but there was a lack of studies in China. This research aimed to study the relationship between impulsive personality traits and suicidal behavior among Chinese rural youths. Suicides were consecutively sampled from six randomly selected counties in Liaoning Province in China. Between 2005 and 2007, a total of 162 suicide victims were enrolled in the study along with 162 community controls matched for age, gender, and location. The psychological autopsy method was used to collect data from informants knowledgeable about the selected suicide victims and controls. The results showed the suicide victims in the study were more likely to demonstrate dysfunctional impulsivity and less likely to demonstrate functional impulsivity compared with the controls. Mental disorders, acute negative life events, and dysfunctional impulsivity contributed to the risk of suicide; educational and functional impulsivity were protective factors. Suicide prevention efforts in rural China may address impulsivity.     

Career success criteria and locus of control as indicators of adaptive readiness in the career adaptation model

The present research had two goals. The first goal was to identify additional individual characteristics that may contribute to adaptive readiness. The second goal was to test if these characteristics fit the career adaptation model of readiness to resources to responses. We examined whether career success criteria (measured at Time 1) and career locus of control (measured at Time 1) would contribute to adaptivity and predict university students’ career decision-making self-efficacy (measured at Time 2) through the mediation of career adaptability (measured at Time 1). Results based on a two-wave survey among a sample of 437 Chinese university students showed that the criteria of intrinsic fulfillment and work-life balance, as well as internal career locus of control positively predicted Chinese university students' career adaptability, which in turn predicted career decision-making self-efficacy. These findings support the career adaption model and carry implications for career construction theory and university students' career development.     

影响再次侵犯的实验研究:报复、惩罚、沉默、还是宽恕?

本研究从侵犯者角度出发,探讨受害者不同应对策略是否会影响侵犯者的再次侵犯。研究1采用囚徒困境范式,考察62名大学生应对策略和报复机会对再次侵犯的影响。研究2采用故事情境法,考察227名被试应对策略、年龄对悔改动机和再次侵犯的影响。结果发现,应对策略、年龄的主效应显著,二者交互作用显著,被试年龄越大对报复者侵犯的可能性越低。启示我国目前仍应以报应性司法模式为主,可在青少年群体尝试恢复性司法。。
