The call developmental process of Psittacula agapornis consists of five instinct phases according to its call character. In the first phase (congenital cal1 phase, CCP, 0~12 day of age), the juveniles only produce single syllable with short syllable length. The second phase(blank-model-forming phase,BMFP, 13~30 day of age) is important for formation of vocal learning pathways. During this phase, the calls characterized by more and longer syllables. In the third phase (call-model-forming phase,CMFP, 31~45 day of age), the call development is guided by a model system for vocal learning, vocal learning is engendered so that some calls with multi-syllables with UP1 are produced, principal frequency has increased about by 920 cent, the number of note is double that of second phase. The short-term memories are transformed into long-term memories in the forth phase (call-feedback-learning phase,CFLP, 46~90 day of age). The call of juveniles is a close match to tutor call which accompanied by double various sounds with BS and UP1, and more resonance components were formed. Second principal frequency has increased about by 970 cent, the number of note increases by 2.6~3.0 times. During the fifth phase (excellent call phase,ECP, after 91 d), vocal motor pathway is developed and the calls are accompanied with most stable, harmonious vari-tone and complex repertoire.
牡丹鹦鹉的鸣声发育分为5个时期。0~12 d为先天性鸣声期,鸣声特征为以基本音为主音的单音节单音调声,声长短。13~30 d为空白模板形成期,鸣声特征为以基本音为主音的多音节单音调声,声长和音量显著性增加,表明发声学习通路开始形成。31~45 d为鸣声模板形成期,鸣声特征为以第1陪音(UP1)为主音的多音节单变调声,声长和音量显著性增加,主音频提升约920音分,涵盖的律音数增加1倍,表明发声学习模板逐渐形成,发声学习开始。46~90 d为鸣声反馈学习期,鸣声特征为以BS和UP1为主音的双变调声,声长和音量显著性增加,主音频涵盖的律音数增加2.6~3.0倍,第2主音频提升约970音分,表明稳定模板逐渐形成,短期记忆逐渐向长期记忆转化。91 d后为完美鸣声期,鸣声特征为以UP1为主音的复合变音调声,声长、音量、主音频的提升和涵盖的律音数都趋于平稳,鸣声稳定而和谐,表明发声运动通路基本形成。

Results In early stage group, 5 of 60 cases appeared enophthalmos in first week(8.33%), 48(80%)cases appeared in second week, 53(88.33%)cases appeared in third week. No significant difference was found in second week and third week(χ2=1.563, P<0.001. There were significant difference between the first week and second week(χ2=62.484,P<0.001 ,the first week and third week(χ2=76.885,P<0.001). There was significant linear correlation between expansion of the orbital volume behind the axis of the globe and the degree of enophthalmos(r=0.994,P<0.001,with each 1.0ml expansion in the orbital volume behind the axis of the globe causing approximately 1.0mm enophthalmos.
结果:早期组60例患者中,5(8.33%)例患者在1周内出现眼球内陷,48(80%)例在2周内出现内陷, 3周时有53(88.33%)例呈现出内陷;2周时出现眼球内陷的例数与1周时有显著性差异(χ2=62.484, P<0.001),2周时出现眼球内陷例数与3周时无差异(χ2=1.563, P>0.05),1周时出现眼球内陷例数与3周时有显著差异(χ2=76.885,P<0.001),后部眶容积增大与眼球内陷的比值约为1.0,两者之间呈正相关(r=0.994,P<0.001),即后部眶容积每增加1ml,产生1.0mm的眼球内陷。

The experiments showed that deception is a developing skill in the preschool years and includes three stages: the first is the behaviorism stage of deception,the second is the mentalistic stage of deception based on the first-order belief,and the third is the mentalistic stage of deception based on the second-order belief.3-year-old children are at the first stage,4-and 5-year-old children are at the second stage,and 6-year-old children begin to enter the third stage.
但那时的研究者都是站在行为问题或道德问题的角度对人类的欺骗行为进行研究。20世纪80年代,儿童心理知识发展的第三个研究浪潮———&心理理论&出现以后,发展学家们开始从心理理论的视角探讨儿童欺骗的发生发展,并从信念的层面对欺骗进行了科学的界定,认为欺骗就是指意图培养他人的错误信念,以使他人产生错误或进入这一误区的行为[1,2]。近几十年来西方研究者对儿童欺骗的研究主要集中于探讨儿童欺骗的发生发展特点[3]。
