西北农村地区母亲抑郁与幼儿社交退缩:母亲回应性的中介作用

以甘肃省陇南市成县6所幼儿园301名农村幼儿及其母亲为研究对象,采用流调中心抑郁量表（CES-D）、母亲教养方式量表和Achenbach儿童行为量表（CBCL）分别考察母亲抑郁、母亲回应性和幼儿社交退缩的现状及相互关系。主要结果如下：（1）西北农村地区母亲抑郁发生率较高,父亲外出打工和贫困家庭的母亲抑郁发生率更高;（2）母亲抑郁与幼儿社交退缩行为显著正相关,母亲抑郁水平越高,幼儿社交退缩得分越高;（3）母亲敏感性和反应性与幼儿社交退缩显著负相关,母亲敏感性和反应性得分越高,幼儿社交退缩得分越低;（4）母亲反应性在母亲抑郁和幼儿社交退缩之间起部分中介作用。     

儿童早期的母亲生活压力对其5岁行为问题的预测效应：链式中介分析

通过对107名幼儿及其母亲历时5年的5次追踪测量, 考察了儿童早期(9~38个月)母亲生活压力对5岁时儿童行为问题的预测效应及其作用机制。结果发现, 在儿童早期, 母亲生活压力具有相对的稳定性, 但引起母亲生活压力的主要生活事件排序有所变化; 儿童早期母亲生活压力对儿童行为问题的作用机制有两种方式：一方面表现为母亲生活压力对儿童5岁时的情绪症状和品行问题的直接效应; 另一方面表现为通过减少母亲积极养育行为进一步影响儿童情绪症状和同伴问题的间接效应; 此外, 儿童早期母亲生活压力还通过积极养育和儿童努力控制的链式中介作用对儿童过度活跃和亲社会行为产生影响。结论:母亲生活压力对儿童行为问题具有预测效应, 这种效应的机制包括母亲生活压力的直接效应以及通过积极养育、努力控制的间接效应。     

学步儿童的不顺从行为与亲子互动的关系

通过对138名学步儿童及其母亲的观察研究,分析儿童的不顺从行为与亲子互动之间的关系。结果表明:(1)在亲子互动中,母亲的言语策略多于身体策略。(2)母亲的模糊言语显著地正向预测儿童的反抗,母亲的远处身体指导显著地正向预测消极不顺从。(3)母亲的反应性与明晰言语、模糊言语、积极身体指导和远处身体指导正相关,与严厉言语和消极身体指导负相关。(4)儿童反应性负向预测消极不顺从和拒绝/协商行为。     

父母意识的影响因素分析

本研究运用父母意识调查表分析探讨父母意识可能的影响因素,主要得出如下结论:①父母的年龄对母性意识和父性意识有明显的影响,而父亲的文化水平、职业对其父性意识没有显著影响;②母亲的文化水平、职业对其母性意识有明显的影响,而父亲的文化水平、职业对其父性意识没有显著影响;③家庭中由不同的人来承担抚养孩子的职责,对父性意识和母性意识均有较大的影响,并且这种影响对父母有明显的不同;④孩子的年龄和性别对总体的母性意识没有显著影响,但影响母性意识的某些构成因子;孩子的年龄对总体的父性意识没有显著影响,但影响父性意识的某些构成因子;孩子的性别明显影响其父亲的父性意识;⑤居住地不同对父母意识没有明显影响。     

幼儿外倾性与攻击行为的关系:自我控制和母亲温暖教养的调节作用

本研究以上海市某幼儿园的237名3~6岁幼儿为被试,请母亲填写幼儿气质及教养方式问卷,幼儿园教师评定幼儿的攻击行为,探讨幼儿外倾性与攻击行为的关系,以及自我控制和母亲温暖教养方式在其中的保护作用。结果表明,自我控制和母亲温暖可以调节幼儿外倾性与攻击行为的关系。与较低的自我控制和母亲温暖的幼儿相比,幼儿较高的自我控制和母亲温暖,可以弱化外倾性与攻击行为的正向关联。结果揭示了自我控制和母亲温暖对幼儿外倾性具有保护作用,有助于减弱这些个体的攻击行为。     

Maternal aggression in mice: Protection of young is a by-product of attacks at the home site

Lactating female mice attacked male intruders in their home cages but showed little attack behavior either in novel cages or in cages with which they had been familiarized. Presence or absence of young did not determine the occurrence of maternal aggression, whereas attacks on the young by the intruder decreased maternal aggression and increased cannibalism of pups by the dams. Apparently, if the function of maternal aggression in mice is protection of the young, such protection occurs because the pups are in a place where attacks are likely to occur and not because the dam “defends” the young.     

Maternal aggression in mice: The non-specific nature of the exteroceptive maintenance by young

Five hours of pup removal during early lactation (Postpartum Day 6) reduced maternal aggression in mice, while placement of the dam's entire litter (six pups) or a single pup behind a double wire mesh partition in the homecage maintained aggression at a level identical to that of mothers in direct contact with their young. When placed behind the partition, unfamiliar 6, 13, and 20-day-old pups, but not 30-day-old mice, maintained the behavior as effectively as the dam's own young. The relationship of the findings to communal rearing conditions in the mouse is discussed.     

Kinship does not affect litter defence in pairs of communally nesting female house mice

Communal litter defence by sister and nonsister female mice can provide a valuable experimental paradigm to test whether females invest preferentially in kin. Since females within sister and nonsister pairs have different coefficients of relatedness with the young, the cumulative litter has more fitness value for related than for unrelated partners. Sister and nonsister paired females that gave birth simultaneously (n = 18), or at least within 7 days from each other (n = 12), were tested for maternal aggression on post partum day 7, or 10 days after the first delivery, respectively. Sister (n = 14) and nonsister pairs (n = 16) did not differ in cumulative values of post partum aggression or in the extent to which aggression was balanced within the pair. The aggressive behavior of each female was not correlated with her relative proportion of pups in the litter. Rather, the combined scores of aggression within the pairs were found to be positively correlated with the cumulative litter size. The analysis of mouse litter defence behavior shows that, under conditions of communal nesting, kinship does not seem to affect parental investment in the young significantly. Rather, the cumulative litter size could be used by paired females as a major indicator for parental investment allocation.
