Abstract： The studies for body recognition processing often focus on inverted body. And the body inversion effect refers to the fact that the reaction time to identify the inverted body is longer and the correct rate is lower than that to the upright body. Recently, researchers have used a variety of techniques to examine the effect and its configural processing mechanism, in which there are still controversy about the role of head information. In addition, now available body inversion effect mainly concentrated on the configural processing theory and the configural processing continuum theory, however there are still some discrepancies between the two theories in terms of the subcomponents involved in the configural processing. Further researches, with more special populations involved, can focus on the improvements of relevant theories and the specific role of head information, through using materials of high ecological validity.

Abstract： The human parental brain could be defined as is the network of regions that support caregiving behaviors to identify and react to infant related stimuli (infant vocals and facial expressions). First, we reviewed the neural circuits that were demonstrated to be involved in establishing and maintaining parent-infant relationships, which included circuits for motivation-reward, empathy, emotion regulation and executive function. And the important brain areas incorporate the orbitofrontal cortex, anterior cingulate cortex, anterior insula, amygdala, and supplementary motor area. Second, the current review summed that human parental brain is sensitive to multiple parenting determinants, including parenting abilities, parental hormones and psychopathology. The growth of parenting abilities and the improvement of oxytocin levels are beneficial to the processing for infant stimuli. Finally, several advices were proposed for future directions: 1) prospective and longitudinal studies across important transition periods for parenting; 2) describing the neural basis of male psychopathologies and exploring targeted interventions and treatments; 3) employing some advanced neuroscience technique (e.g., hyper scanning) to highlight the simultaneous neural activity between mother and father or parents and infants; and 4) conducting parental brain research in Chinese culture.

Abstract： The integration of various emotional information from different modalities (e.g., face and voice) plays an important role in our interpersonal communication. In order to understand its brain mechanism, more and more researchers found that the interaction between facial expression and vocal emotional information begins in the early stage of perception, and the integration of emotional information content occurs in the late decision-making stage. In the early stage, the primary sensory cortex is responsible for encoding information; while in the late stage, the amygdala, temporal lobe and other advanced brain regions are responsible for cognitive evaluation. In addition, the functional coupling of oscillation activities on multiple frequency bands facilitates the integration of emotional information cross channels. Future research needs to explore whether facial expression and vocal emotional information integration is associated with emotional conflict, and whether inconsistent emotional information has advantages. Lastly, we should find out how the neural oscillations of different frequency bands promotes the integration of facial expression and vocal emotional information, so as to further understand its dynamic basis.

Abstract： The body contains rich social information. Studying the body representation’s development in the early stage is significant for revealing body representation’s specific mechanism and further understanding the infants’ social development. Through looking at the theories about the body shape and the body movement, we summarize the representation patterns of the infant’s body structure information and movement information. At the same time, the article describes two theories on the infant's body representation development. Future researches should pay more attention to explain the specific development process and the controversial critical period of body representation in fancy. Moreover, the mechanism of biological motion preference on body representation should be explored through using the brain imaging technology.

Abstract：为探讨畦长对冬小麦耗水及产量和水分利用特性的影响, 本试验以冬小麦品种‘科农2011’为试验材料, 在2014—2015 年中国科学院栾城农业生态系统试验站小麦生长季, 畦宽为5 m 条件下, 设置4 m、5 m、10 m(农民习惯畦长)、50 m、100 m 共5 个畦田长度, 各处理均在拔节期和灌浆期用塑料软管从机井口引水到畦首灌水, 塑料软管出水口安装水表计量灌水量, 用秒表计量灌溉用时, 研究不同畦长处理对冬小麦水特性、灌溉定额及灌溉用时、畦田内不同部位土壤含水量差异、籽粒产量以及产量和灌溉水利用效率的影响。结果表明: 随着畦长增加, 灌水量和总耗水量逐渐增加, 灌水量占总耗水量的比例逐渐增加; 籽粒产量虽逐渐增加, 但未达到显著水平。土壤储水消耗量、产量水分利用效率和灌溉水利用效率随着畦长增加逐渐降低。与农民习惯的畦长10 m 相比, 4 m 畦长处理的灌水量减少34.50%, 多消耗深层土壤贮水58.92 mm, 总耗水量降低1.61%, 产量水分利用效率提高1.15%, 灌溉水利用效率提高51.96%, 次灌溉用时减少42.75%。100 m 畦长处理在产量没有显著提高的基础上, 总耗水量增加9.58%, 灌溉水增加38.08%, 产量水分利用效率降低9.88%, 灌溉水利用效率降低26.20%, 次灌溉用时增加65.61%。综合考虑籽粒产量、灌水量和水分利用效率, 4 m畦长是本试验条件下兼顾高产与节水的最优畦长处理。

Abstract：在旱作条件下, 探讨播期及播量对小麦新品系‘小偃60’群体性状、产量及水分利用的影响, 可为小麦适雨栽培提供技术依据。试验于2014—2015 年在中国科学院南皮生态农业试验站进行, 自10 月15 日至11 月14 日, 每6 d 设置一个播期, 共设6 个播期(T1~T6), 设播量不变(B1)和逐期增加播量(B2)两个处理: B1 为 300 kg·hm2, T1 到T6 播量相同; B2 为随播期推迟播量逐期增加, 每推迟1 d 增加7.5 kghm2, 各播期的播量分别为300 kg·hm2 (T1)、345 kg·hm2 (T2)、390 kg·hm2 (T3)、435 kg·hm2 (T4)、480 kg·hm2 (T5)和525 kg·hm2(T6), 研究了不同播期和播量下‘小偃60’群体性状、产量及水分利用的变化规律。试验结果表明: 1)随播期推迟, 出苗时间延长、生育期推迟, 全生育缩短; 播量对生育期无显著影响。2)随播期推迟, 出苗率和单株成穗数逐渐降低; 播量增加, 基本苗及穗数提高。3)随播期推迟, 株高和生物量降低; 播量增加, 生物量提高, 株高无显著变化。4)随播期推迟, 籽粒产量下降; 逐期增加播量后, 11 月2 日前籽粒产量可达6 600 kghm2 以上且无显著差异。5)若随播期推迟增加播量, 前4 个播期产量、水分利用效率无显著变化, 皆达29 kghm2mm1以上。研究结果表明, ‘小偃60’是一个播期宽泛的品种, 随播期推迟产量下降, 但在一定播期范围内通过增加播量, 提高群体(穗数), 可以获得与适时播种相近的产量, 播量与播期推迟天数的理论关系为y=0.368 2x2+1.193 9x+316.7 (R2=0.983 9)。
