Both maternal sensitivity and atypical maternal behavior independently predict attachment security and disorganization in adolescent mother-infant relationships

Extant theory holds that variation in attachment security is largely determined by caregiver sensitivity whereas disorganization has its roots in atypical interactions that frighten the infant. These hypotheses were confirmed in the current study of a high-risk sample but, contrary to current theory, both atypical maternal behavior and maternal sensitivity were also significant independent predictors of attachment disorganization and security.     

Infant‐holding biases in mothers and affective symptoms during pregnancy and after delivery

Several authors have reported that participants have a leftward bias when holding a newborn or young infant. Our study of mothers met before and after their infant's birth sought to ascertain whether particular combinations of affective symptoms (depression, anxiety) and holding positions (horizontal versus vertical) were related to holding‐side biases. Our results showed that (a) mothers displayed a significant leftward (71%) holding bias, (b) mothers with affective symptoms held their newborn on the right side and more frequently in the vertical position, and (c) hemispheric specialization for perceiving visual emotions had no significant effect on the holding‐side biases of new mothers. These results suggest that maternal affective symptoms have a dominant effect on the determination of holding‐side preferences, when associated with a particular holding position.

Maternal territoriality as an offspring defense strategy in red swamp crayfish (Procambarus clarkii,Girard)

The offspring‐defense hypothesis of maternal territoriality in solitary and semisocial mammals [Wolff JO and Peterson JA. 1998. Ethol Ecol Evol 10:227–239] was evaluated in another taxon using maternal and nonmaternal female red swamp crayfish (Procambarus clarkii), a freshwater decapod crustacean that shows pronounced shelter‐related maternal aggression. The maternal females were of three different categories: (1) ovigerous, (2) carrying primarily stage 1 offspring, or (3) tending offspring that were primarily stage 2. Each female was in residence in an individual aquarium containing only a gravel substrate for 24 hr prior to serial intrusions by male conspecifics. Virtually all of the residents, maternal and nonmaternal, excavated a depression (shelter) in the substrate prior to the first intrusion. The results showed that residents in each of the maternal categories won a significantly higher proportion of their encounters than did the nonmaternal residents, which showed only negligible defense and lost every encounter. However, there were no significant differences in encounter outcomes between the maternal resident categories. There was clear defense of the shelter by maternal females, with virtually all fighting being in or around it, thus demonstrating stable, heightened territorial defense throughout these maternal phases of reproduction. This support of the offspring‐defense hypothesis of maternal territoriality is the first such evidence for a freshwater crustacean and is very similar to that recently reported in a related marine decapod, the American lobster (H. americanus).

父亲的角色态度对其教养投入的影响：母亲态度类型的调节作用

本研究采用双亲关于父亲角色的态度问卷及父亲教养投入问卷,对427个3~7岁儿童的父母进行调查,考察父亲关于自身角色的态度对其教养投入的影响以及母亲关于父亲角色的态度类型在其中的调节作用.结果表明:(1)父亲关于自身教养价值、教养动机、教养技能的态度均可正向预测其教养投入,而父亲关于自身教养天性的态度对其教养投入没有显著的预测作用;(2)母亲态度类型在父亲的教养动机与其教养投入之间具有调节作用,在父亲角色态度的其他维度与教养投入之间无显著的调节效应.当母亲为矛盾型和拒绝型时,父亲的教养动机可正向预测其教养投入;当母亲为接纳型时,父亲的教养动机对其教养投入不具有预测作用.     

从母亲的敏感性到学步儿的依恋安全性：内部工作模式的桥梁作用

采用视觉习惯化实验程序、陌生情境技术及母亲行为Q分类方法对41名14个月的学步儿及其母亲进行了学步儿内部工作模式、学步儿在陌生情境中的依恋类型以及母亲在母婴互动中的敏感性的评估。结果发现：(1)不安全型的学步儿预期看护者对他们痛苦的信号是无回应的。(2)以自身为中心的母亲的学步儿预期看护者是无回应的。(3)潜类别分析的结果发现母亲敏感性影响学步儿依恋行为的2种关系模式：类别1, 以孩子为中心的母亲的学步儿更容易形成看护者是有回应的预期, 持这种预期的学步儿在陌生情境程序中表现出安全依恋行为; 类别2, 以自身为中心的母亲养育出的学步儿更容易对看护者形成无回应的预期, 并在陌生情境中表现出不安全依恋行为。研究表明：内部工作模式在母亲的敏感性和学步儿的依恋安全性之间起着重要的内部机制作用—— 母亲的敏感性行为的累积促进了学步儿内部工作模式关于母亲的预期, 这种预期又进一步引导着学步儿的依恋行为。     

青少年心理行为问题与专业心理求助态度：父母知晓的中介作用

摘 要 对831名中学生施测青少年自评量表、父母知晓量表、专业心理求助态度问卷,考察青少年心理行为问题、父亲知晓、母亲知晓与专业心理求助态度的关系。结果发现：（1）青少年的专业心理求助态度与心理行为问题、父母知晓呈显著相关。（2）父亲知晓在青少年心理行为问题与专业心理求助态度的关系中起部分中介作用,母亲知晓的中介作用不显著。研究结果对青少年专业心理求助的干预有着重要意义。     

母亲抑郁和惩罚对儿童早期问题行为的影响及父亲的保护作用

儿童早期是母亲消极情绪和行为的易感期,母亲抑郁和消极的教养行为可能导致儿童早期多方面的发展问题,而父亲的积极教养则可能对孩子的健康发展起到保护作用。本研究以184名学前儿童的父亲和母亲为被试,考察母亲抑郁情绪和惩罚行为对儿童问题行为的影响及作用机制,以及父亲积极鼓励在其中的调节作用。结果发现:(1)母亲抑郁显著预测儿童的内向问题行为,母亲惩罚显著预测内向和外向问题行为;(2)母亲抑郁完全通过其惩罚行为影响儿童的外向问题行为,部分通过惩罚影响儿童的内向问题行为;(3)父亲积极鼓励显著调节母亲抑郁对外向问题行为的影响,边缘显著调节母亲抑郁对内向问题行为的影响;父亲积极鼓励对母亲惩罚与内、外向问题行为之间的关系的调节不显著,表明积极的父亲鼓励可以缓冲母亲抑郁对儿童问题行为的影响。
