Observer age and the social transmission of attractiveness in humans: Younger women are more influenced by the choices of popular others than older women

Being paired with an attractive partner increases perceptual judgements of attractiveness in humans. We tested experimentally for prestige bias, whereby individuals follow the choices of prestigious others. Women rated the attractiveness of photographs of target males which were paired with either popular or less popular model female partners. We found that pairing a photo of a man with a woman presented as his partner positively influenced the attractiveness of the man when the woman was presented as more popular (Experiment 1). Further, this effect was stronger in younger participants compared to older participants (Experiment 1). Reversing the target and model such that women were asked to rate women paired with popular and less popular men revealed no effect of model popularity and this effect was unrelated to participant age (Experiment 2). An additional experiment confirmed that participant age and not stimulus age primarily influenced the tendency to follow others' preferences in Experiment 1 (Experiment 3). We also confirmed that our manipulations of popularity lead to variation in rated prestige (Experiment 4). These results suggest a sophisticated model‐based bias in social learning whereby individuals are most influenced by the choices of those who have high popularity/prestige. Furthermore, older individuals moderate their use of such social information and so this form of social learning appears strongest in younger women.     

Maternal Trauma and Children’s Functioning: The Role of Kinship Social Support

Although research has documented the detrimental effects of maternal trauma on child behavior (Lambert, Holzer, & Hasbun, 2014), the role of extended family support in potentially mitigating the effects of intergenerational transmission of trauma is not clearly understood. With a diverse community sample of 52 trauma-exposed mothers and their children between the ages of 7 and 12, we investigated relationships between kinship social support, maternal trauma exposure severity, maternal posttraumatic stress disorder (PTSD) symptom severity, and child behavioral problems. Results showed that kinship social support was negatively related to maternal trauma exposure severity, maternal PTSD symptom severity, child internalizing behaviors, and child externalizing behaviors. Additionally, kinship social support moderated the relationship between maternal trauma exposure severity and child internalizing behaviors. These results have implications in the implementation of interventions aimed at supporting diverse families facing trauma that incorporate extended family networks.     

Family Therapy with Families of Holocaust Survivors

This is a clinical review of 7 families of Holocaust survivors who presented for treatment because of problems with an adolescent of the third generation. In 3 cases the problem was anorexia, and the remaining 4 had various clinical presentations, mostly related to separation-individuation issues. A common thread in the narratives that unfolded was that the trauma of the grandparent/survivors had been transmitted across subsequent generations to exercise significant influence on the children and grandchildren. Often, a more recent death or separation crisis had been the catalyst for these difficulties or a trigger that activated the Holocaust trauma. An outline of the therapeutic intervention is presented; it was based on a combination of systemic, structural, strategic, and psychodynamic approaches. It is suggested that open acknowledgment of the transgenerational issues played a critical role in moving families toward a more differentiated outcome.     

Experiences of Families Transmitting Values in a Rapidly Changing Society: Implications for Family Therapists

Intergenerational value transmission affects parent–child relationships and necessitates constant negotiation in families. Families with adolescents from rapidly changing societies face unique challenges in balancing the traditional collectivistic family values that promote harmony with emerging values that promote autonomy. Using modern Turkey as an example of such a culture, the authors examine the transmission process in families that hold more traditional and collectivistic values than their adolescent children. Special consideration is given to generational and cultural differences in the autonomy and relatedness dimensions.     

网络突发事件中的负性偏向：产生与表现

在网络突发事件的产生和传播中, 人们往往更关注负面信息的加工和传递, 存在负性偏向。本研究依据事件酝酿、爆发、蔓延阶段的特征, 构建心理机制模型, 通过3项研究分别检验了信息内容、信息加工和信息传递中负性偏向的产生和发展。结果表明, 负性偏向不仅产生于网络突发事件的源头语篇中, 还产生于个体信息加工和人际信息传递过程, 表现为个体对负性词汇更好的记忆效果及更高的辨别力, 以及网民间对负性信息的选择性传递和对模糊信息的负性解读。研究有利于认识网络突发事件信息传播规律, 科学应对舆情危机, 创新网络治理。     

双元孝道代际传递:亲子性别和子女年龄的调节作用

配对调查了591户家庭的亲子被试,考察了亲子女性别、子女年龄对双元孝道代际传递的影响。结果显示：（1）权威性孝道和互惠性孝道分别在父亲、母子与子女之间具有相似传递模式,但母亲互惠性孝道还能够预测子女权威性孝道;（2）子女性别能显著调节整个模型,母亲互惠性孝道能预测男性子女权威性孝道,但不能预测女性子女的权威性孝道,且母子之间互惠性孝道传递效应显著高于母女,并显著高于父子之间的同一路径系数;（3）子女年龄对模型的部分路径系数具有显著调节作用,母亲互惠性孝道仅能预测成年子女权威性孝道,母亲对成年子女的互惠性孝道代际传递效应显著高于父亲对成年子女,而父亲对青少年子女的互惠性孝道代际传递效应显著高于其对成年子女。据此研究结果,亲子性别和子女年龄是影响双元孝道代际传递的重要“传递带”。     

Effects of temperature and electron energy on the electron-irradiation-induced decomposition of sapphire

The effects of temperature and electron energy on the electron-irradiation-induced decomposition of sapphire have been investigated by in situ transmission electron microscopy (TEM). It was found that the decomposition rate of α-Al₂O₃ increased with increasing irradiation temperature and decreased with increasing acceleration voltage. The core-hole Auger decay process (K–F model), rather than knock-on displacement, is responsible for the decomposition of α-Al₂O₃ under electron irradiation.     

Structure of Al–Co–Ni pentagonal quasicrystal studied by HAADF-STEM and ab initio calculations

Using a combination of atomic-resolution high-angle annular dark-field (HAADF) Z-contrast imaging and ab initio calculations, atomic models of clusters 2 nm in diameter and 0.8 nm in height are proposed for the Al–Co–Ni pentagonal quasicrystal. This quasicrystal has 5-fold symmetry (the so-called 5f state) without superstructures, and is one of numerous modifications of the Al–Co–Ni decagonal quasicrystal. HAADF results reveal that the two-dimensional quasi-periodic lattice contains mainly Penrose pentagonal tiling. The centres within the decorated pentagonal tiles, i.e. the so-called pentagonal super-clusters, show structural characteristics having both a satellite-orbit shape and a pentagon-symmetry shape. The proposed atomic models, based directly on the HAADF images, are subjected to ab initio total energy calculations. After relaxation, the calculations demonstrate that the models with 5-fold symmetry are energetically more favourable than those with 10-fold symmetry.     

Precipitate characteristics and selected area diffraction patterns of the β′ and Q′ precipitates in Al–Mg–Si–Cu alloys

In this study, the precipitate characteristics and selected area diffraction patterns (SADP) of the β?′ and Q?′ precipitates formed at the over-aged state of Al–Mg–Si–Cu alloys are systematically investigated by means of high-resolution transmission electron microscopy and transition matrix. The β?′ precipitates have two cross-sections, rectangle-shaped and round-shaped aligned with [0?0?1]_Al direction, but only rectangle-shaped cross-section exists for Q?′ precipitates. And, both of them have 12 variants and orientations with Al matrix. However, there are only three different zone axes, [0?0?0?1]_β?′, [1?4?5?0]_β?′, and [5?4?1?0]_β?′ for β?′ precipitates, and [0?0?0?1]_Q?′, [1?4?5?0]_Q?′, and [3?2 1?0]_Q?′ for Q?′ precipitates, parallel to the [0?0?1]_Al direction when they are precipitated from the Al matrix, respectively. Then, a new [0?0?1]_Al SADP model, which superposes diffraction patterns of the β?′ and Q?′ precipitates, is established. Furthermore, some “cross-shaped” diffraction streaks appeared at over-aged state can be explained reasonably by this model, which is good in agreement with the experimental data.
