视觉和听觉通道下减法与乘法心算加工的ERP特征

研究加工通道的差异以及减法和乘法心算的编码特征,选择100道心算算式,在视觉和听觉两种输入通道下记录并分析了14例正常人的脑事件相关电位(ERP)。结果发现,视觉和听觉通道引发了趋势相反的早中期成分,在额区和中央区产生了显著分离。在慢波阶段,听觉通道下更多激活了颞区,而视觉通道下更多激活了顶-枕区,且慢电位的ERP特征也表现出通道差异。减法和乘法运算以左半球激活为主,但听觉通道下的顶区和颞区出现了显著的右半球优势。减法在视觉通道下优势较大,说明其主要依赖视空间表征;而乘法在听觉通道下更具优势,则主要是由于其以听觉的言语表征方式为主。     

Effects of Guided Notes on Enhancing College Students’ Lecture Note-Taking Quality and Learning Performance

This study investigates the intervention effects of guided notes on college students’ quality of lecture note-taking and learning performance under the provision of outline notes. It adopted a quasi-experimental pretest–posttest–delayed-posttest design. Sixty-five undergraduates from two psychology classes in a university were recruited as participants. One class was assigned to the experimental group and the other to the control group. Students in the experimental group were provided with outline note plus guided note handouts and asked to complete the guided notes in class, whereas students in the control group received outline note handouts only. The results showed that (1) in the delayed posttest, the experimental group performed better than the control group on the quality of note-taking; (2) in the posttest and delayed posttest, the experimental group performed better than the control group on learning performance; (3) the experimental group had a positive attitude towards the guided notes.     

Patient Perspectives on Intimate Partner Violence Discussion during Genetic Counseling Sessions

Intimate partner violence (IPV) is a major health concern in the United States (ACOG 2013). The World Health Organization (WHO) describes IPV as any physical, sexual, psychological harm by a current or former intimate partner (WHO 2016). Due to the psychosocial depth and nature of discussions within genetic counseling sessions, patients may disclose and/or discuss IPV as it relates to sexual well-being, reproductive and overall health. This study aims to assess the role for IPV screening, counseling and intervention in genetic counseling practice by investigating the incidence, experiences and attitudes about IPV among genetic counseling patients. Patients receiving genetic counseling at an urban metropolitan hospital were anonymously surveyed about experiences and perspectives on IPV as a topic of discussion during genetic counseling sessions. Among 60 eligible patients, 50 completed the survey (49 females, 1 male, of which, 5 identified as LGBT) ages 20 to 66. The incidence of IPV in this group was 16.0 % (n = 8). Majority of participants had never been asked about IPV by a healthcare provider (n = 32; 64.0%), would have felt comfortable answering questions about IPV by their healthcare provider (n = 34; 68.0%), and would have felt comfortable answering questions about IPV by their genetic counselor (n = 39; 78.0%). Perspectives from all participants, notably those with IPV history, provided insights to the role of genetic counselors in areas for IPV screening and counseling training.     

Optimal Items for Assessing Parental Involvement across Different Groups During Middle Childhood

Various definitions and different approaches for assessing the complex construct of parental involvement (PI) have led to inconsistent findings regarding the impact of PI on child development. To date, limited information is available regarding the measurement invariance of PI measures across time and groups (e.g., children’s gender, ethnicity, and socio-economic status), leaving a concern that group differences in PI might reflect item bias instead of true differences in PI. The present study aimed to obtain a set of optimal items for measuring PI from kindergarten through the elementary school years and investigate whether they could be used for parents from different groups. A Rasch measurement model was implemented to investigate item difficulty, step calibrations, and measurement invariance (differential item functioning; DIF, here). The results from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 data set showed that 20 items can be used to measure three dimensions of PI—namely school/home involvement, family educational investment, and family routines—across four time points. Administrative time, children’s gender, ethnicity, and social economic status showed different levels of effect on item difficulty for half of these items. Practitioners and researchers should be cautious when using these items and are suggested to freely estimate the item parameters of DIF items as well as add more items to the PI scale to improve reliability.     

Gender,Sexuality, and Social Change in Contemporary China

Drawing upon Raymond Williams’ notion of culture and in-depth interviews with 40 women, this article examines forces that have shaped the landscape of sexuality in China. It argues that the process of changing sexuality contains multiple and overlapping forms of sexual culture, in which the party-state’s ideology, emergent sexual cultures and traditional Chinese beliefs intertwine and struggle. In addition to age-based differences in attitudes towards sexual practices within studies of youth culture, this study incorporates a class-based variable into the account.     

A survival analysis of the impact of boundary crossings on managerial career advancement up to midcareer

Although managers and professionals still compete in a career tournament for advancement and pay, the career boundaries that they cross in order to compete have changed. Traditionally, such individuals came up through the ranks within the same company by specializing in one functional area and changing, as needed, the geographic location of work in order to advance their careers. However, in the current era of less constrained, boundary-crossing careers, they are more apt to cross several boundaries, including functional, organizational, geographic, and family, as they pursue career opportunities. Using survival analysis with data from the career histories of 760 managers and professionals who collectively made 3917 moves up to midcareer, we examined the impact of the rate of crossing each boundary on the subsequent likelihood of advancement. In addition, over this span of career, we examined the extent to which more rapid advancement contributed to the rate of growth in annual salary. Our findings suggest that crossing functional, organizational, and geographic boundaries more often significantly increased the likelihood of advancement, whereas the duration of family boundary crossings had a negative impact. Moreover, as expected, advancement had a long-term impact on salary growth.     

Preschoolers search for hidden objects

The issue of whether young children use spatio-temporal information (e.g., movement of objects through time and space) and/or contact-mechanical information (e.g., interaction between objects) to search for a hidden object was investigated. To determine whether one cue can have priority over the other, a dynamic event that put these cues into conflict was created, with only spatio-temporal information being valid. The 3-year-olds used in the study were found to use the valid spatio-temporal cue exclusively and seemed to ignore the contact-mechanical cue. Both search behavior and eye tracking during the event support the view of a sophisticated sensitivity to the validity of a cue in indicating a target’s hidden location.     

An analysis of an optimal selection process for characteristics and technical performance of baseball pitchers

Selection of a qualified pitcher has relied previously on qualitative indices; here, both quantitative and qualitative indices including pitching statistics, defense, mental skills, experience, and managers' recognition were collected, and an analytic hierarchy process was used to rank baseball pitchers. The participants were 8 experts who ranked characteristics and statistics of 15 baseball pitchers who comprised the first round of potential representatives for the Chinese Taipei National Baseball team. The results indicated a selection rate that was 91% consistent with the official national team roster, as 11 pitchers with the highest scores who were recommended as optimal choices to be official members of the Chinese Tai-pei National Baseball team actually participated in the 2009 Baseball World Cup. An analytic hierarchy can aid in selection of qualified pitchers, depending on situational and practical needs; the method could be extended to other sports and team-selection situations.     

Repetition benefit in mental rotation is independent of stimulus repetition

In this study, we investigated whether there is a repetition benefit in mental rotation that is independent of stimulus repetition (i.e., due to increased efficiency in postencoding processing). Three experiments were conducted, in which different conditions of stimulus repetition (different letters on consecutive trials in Experiment 1, letters of different orientations on consecutive trials in Experiment 2, and priming of rotation direction in Experiment 3) were used, and the extent of repetition of rotation direction between two consecutive trials was manipulated. The results of all three experiments showed clear evidence of a repetition benefit without repeating the stimulus, suggesting that this effect is independent of stimulus repetition and lending support to the notion of increased efficiency in mental rotation as a result of repeated rotation direction per se.     

Two types of behavioral inhibition: Relations to effortful control and attention in school children

This study aimed to examine the relationship of two types of behavioral inhibition, social inhibition and nonsocial inhibition, to effortful control and attention in 7–9-year olds. Social and nonsocial inhibition and effortful control were assessed by questionnaires. The child version of the Attention Network Task was used to measure attention including alerting, orienting and executive attention. Results indicated that in girls, social inhibition was negatively related to effortful control and alerting, while nonsocial inhibition was positively related to orienting; there was an interaction between social and nonsocial inhibition in predicting executive attention in boys. Thus, it is of great significance to differentiate social and nonsocial inhibition when examining the association between behavioral inhibition and effortful control and attention in school-age children.
