大学生心目中理想教师的因素分析

以160名大学生为被试,采用自制的词表,运用因素分析的方法研究大学生心目中理想教师形象,并比较不同年级、不同性别以及不同学科（文、理）的学生对理想教师形象的要求有何差异。结果发现：（1）当代大学生心目中的理想教师形象应具备四项主要特征：公正平等,师德高尚;讲课生动,见解独到;大方得体,成熟稳重;专业过硬,科研水平高;（2）在“讲课生动,见解独到”这个因素上女生比男生对教师的要求更高一些;（3）在“大方得体,成熟稳重”这个因素上,二、三、四年级间无明显差异,均高于大一学生对教师的要求;（4）在“专业过硬,科研水平高”这个因素上,理科生比文科生对教师的要求更高一些;（5）在“公正平等,师德高尚”这个因素上,性别与年级的交互作用显著。     

测谎中反馈加工的认知神经机制：一项ERP研究

在一个模拟“杀人——侦探”游戏情境中,被试先完成模拟杀人任务,在随后的测谎阶段使用有反馈的ERP测谎范式,以反馈的形式告知被试测谎结果（“+0.5”或“-2”,分别代表“撒谎逃过检测”或“撒谎被发现”）时的脑内时程动态变化。结果发现,在反馈出现后的200～300ms时间段,表示“撒谎被抓住”比“撒谎逃过检测”的反馈信息诱发了一个更正性的ERP成分（P200-300）,在300～400ms时间段,两种反馈诱发的ERP成分（P300）没有差异,而在450～500ms时间段, “撒谎逃过检测”比“撒谎被抓住”的反馈信息诱发了一个更负性的ERP成分（N500）,负性反馈没有诱发FRN。这些结果表明：P200-300、P300和N500都是与加工测谎结果信息有关的ERP成分。P200-300可能对测谎结果的效价（正性或负性）敏感;P300可能反映被试对测谎结果主观意义大小的评价;而N500可能反映测谎结果所导致的大脑皮层兴奋程度。     

Positive emotion modulates cognitive control: An event‐related potentials study

There is substantial evidence to indicate that negative emotion can modulate cognitive control processing. However, only a few studies have investigated this effect with positive emotion. Therefore, the present study explored the electrophysiological correlates of the impact of positive emotional stimuli on cognitive control, using event‐related potentials (ERPs). Sixteen healthy young adults completed a modified Simon task (Simon, 1969). Behavioral data indicated that reaction times were faster for positive emotional stimuli than for neutral emotional stimuli in the incongruent condition, but not in the congruent condition, which suggested that positive emotion expedited conflict resolution. The ERP data showed that two negative ERP components (N300–400 and N450–550) were associated with the positive emotional stimuli in the incongruent minus congruent condition. It is suggested that these components may respectively be related to the conflict monitoring (N300–400) and response selection (N450–550) stages of cognitive control processing. Overall, our results indicated that positive emotion could facilitate cognitive control processing. These results are in line with the neuropsychological theory, according to which, positive emotion could modulate cognitive control mediated by increased dopamine levels in frontal brain areas.     

Asian Couples in Negotiation: A Mixed‐Method Observational Study of Cultural Variations Across Five Asian Regions

The purpose of this study was to explore variations in how contemporary couples from five different Asian regions negotiate disagreements. Video recordings of 50 couples (10 each from Japan, Korea, Mainland China, Taiwan, and Hong Kong) discussing unresolved disagreements provided raw data for quantitative and qualitative analyses. First, teams of coders from each region used a common protocol to make quantitative ratings of content themes and interaction patterns for couples from their own region. An interregional panel of investigators then performed in‐depth qualitative reviews for half of these cases, noting cultural differences not only in observed patterns of couple behavior but also in their own perceptions of these patterns. Both quantitative and qualitative analyses revealed clear regional differences on dimensions such as overt negativity, demand‐withdraw interaction, and collaboration. The qualitative results also provided a richer, more nuanced view of other (e.g., gender‐linked) conflict management patterns that the quantitative analyses did not capture. Inconsistencies between qualitative and quantitative data and between the qualitative observations of investigators from different regions were most pronounced for couples from Korea and Japan, whose conflict styles were subtler and less direct than those of couples from the other regions.     

Male vocal competition is dynamic and strongly affected by social contexts in music frogs

Male–male vocal competition in anuran species is critical for mating success; however, it is also highly time-consuming, energetically demanding and likely to increase predation risks. Thus, we hypothesized that changes in the social context would cause male vocal competition to change in real time in order to minimize the costs and maximize the benefits of competition. To test this hypothesis, we assessed the effect of repeating playbacks of either white noise (WN) or male advertisement calls on male call production in the Emei music frog (Babina daunchina), a species in which males build mud-retuse burrows and call from within these nests. Previous studies have shown that calls produced from inside burrows are highly sexually attractive (HSA) to females while those produced outside nests are of low sexual attractiveness (LSA). Results showed that most subjects called responsively after the end of WN playbacks but before the onset of conspecific call stimuli although call numbers were similar, indicating that while males adjusted competitive patterns according to the biological significance of signals, their competitive motivation did not change. Furthermore, these data indicate that the frogs had evolved the ability of interval timing. Moreover, when the inter-stimulus interval (ISI) between playbacks was varied, the subjects preferentially competed with HSA calls when the ISI was short (<4 s) but responded equally to HSA and LSA calls if the ISI was long (≥4 s), suggesting that males allocate competitive efforts depending on both the perceived sexual attractiveness of rivals and the time available for calling. Notably, approximately two-thirds of male calls occurred in response to HSA calls, a preference rate comparable to that previously found for females in phonotaxis experiments and consistent with the idea that the mechanisms underlying both the male’s competitive responses to rivals and the female’s preferences toward potential mates coevolved under the same selective pressure.     

Dynamics of the relationships among work and family resource gain and loss,enrichment, and conflict over time

Dynamics of the relationships among work and family resource gain and loss, work-to-family enrichment (WFE), and work-to-family conflict (WFC) over time were examined using the data collected from 382 employees of Chinese firms at two points of time one year apart. Work resource gain at time 1 weakened the positive relationship between WFC at times 1 and 2, and work resource loss at time 1 weakened the positive relationship between WFE at times 1 and 2. However, WFC at time 1 strengthened the positive relationship between work resource gain at time 1 and family resource gain at time 2. Overall, these results suggest the existence of complementary forces that maintain the status quo of individuals' work–family experiences, such that high losses diminish the transfer of gains and high gains diminish the transfer of losses, but also that unexpected gains may result from individuals having to deal with painful situations. Implications of these dynamics for theory, research, and practice are discussed.

Odor preference learning and memory modify GluA1 phosphorylation and GluA1 distribution in the neonate rat olfactory bulb: testing the AMPA receptor hypothesis in an appetitive learning model

An increase in synaptic AMPA receptors is hypothesized to mediate learning and memory. AMPA receptor increases have been reported in aversive learning models, although it is not clear if they are seen with memory maintenance. Here we examine AMPA receptor changes in a cAMP/PKA/CREB-dependent appetitive learning model: odor preference learning in the neonate rat. Rat pups were given a single pairing of peppermint and 2 mg/kg isoproterenol, which produces a 24-h, but not a 48-h, peppermint preference in the 7-d-old rat pup. GluA1 PKA-dependent phosphorylation peaked 10 min after the 10-min training trial and returned to baseline within 90 min. At 24 h, GluA1 subunits did not change overall but were significantly increased in synaptoneurosomes, consistent with increased membrane insertion. Immunohistochemistry revealed a significant increase in GluA1 subunits in olfactory bulb glomeruli, the targets of olfactory nerve axons. Glomerular increases were seen at 3 and 24 h after odor exposure in trained pups, but not in control pups. GluA1 increases were not seen as early as 10 min after training and were no longer observed 48 h after training when odor preference is no longer expressed behaviorally. Thus, the pattern of increased GluA1 membrane expression closely follows the memory timeline. Further, blocking GluA1 insertion using an interference peptide derived from the carboxyl tail of the GluA1 subunit inhibited 24 h odor preference memory providing causative support for our hypothesis. PKA-mediated GluA1 phosphorylation and later GluA1 insertion could, conjointly, provide increased AMPA function to support both short-term and long-term appetitive memory.
