Relationships between regulatory temperament dimensions and self-regulatory behaviors at 4 and 6 months of age

The present study focused on relationships between temperament and behavior in early regulation development. Unlike most studies on the topic, we observed infant behavior in a naturalistic playful situation rather than in experimental stressful procedure, and employed temperament measures uniquely reflecting regulatory dispositions rather than a global measure of reactivity. The infant's self-regulatory behaviors were observed at 4 and 6 months during face-to-face interactions and regulatory dimensions were assessed at 4 months. We found that low intensity pleasure and soothability dimensions, related to the infant physical and social experience, respectively, significantly affected regulatory behavior and their influence showed to depend on the infant's age, with the former dimension being influential at the earlier age and the latter being influential when the behavior was observed at the later age. Results are interpreted on the light of a dynamic view of regulation development.     

Is This Relevant? Physician Perceptions,Clinical Relevance,and Religious Content in Clinical Interactions

Despite wide support among physicians for practicing patient‐centered care, clinical interactions are primarily driven by physicians’ perception of relevance. While some will perceive a connection between religion and patient health, this relevance will be less apparent for others. I argue that physician responses when religious/spiritual topics come up during clinical interactions will depend on their own religious/spiritual background. The more central religion is for the physician, the greater his or her perception of religion's impact on health outcomes and his or her inclusion of religion/spirituality within clinical interactions. Using a nationally representative sample of physicians in the United States and mediated path models, I estimate models for five different physician actions to evaluate these relationships. I find that a physician's religious background is strongly associated with whether or not he or she thinks religion impacts health outcomes, which is strongly predictive of inclusion. I also find that not all of the association between inclusion and physicians’ religious background is mediated by thinking religion impacts health outcomes. Issues of religion's relevance for medicine are important to the degree that religious beliefs are an important dimension of patients’ lives.     

Learning blossoms: Caregiver-infant interactions in an outdoor garden setting

Plants provide unique opportunities for learning by engaging all human senses. Recent laboratory studies have shown that infants use a combination of behavioural avoidance and social learning strategies to safely learn about plant properties from adults. Here we investigate how infants and their caregivers interact with plants in an outdoor garden as a first step towards examining the operation of these social learning processes in naturalistic settings. We focus on two specific aspects of spontaneous infant-caregiver interactions with plants: olfactory and touch behaviours. Additionally, we look at whether infants' and caregivers’ prior knowledge of the plants in our study influences infants’ behaviour. Our results showed a multifaceted connection between infants’ and caregivers' previous experience with the plants and their olfactory and touch behaviours. First, infants tended to touch and smell the plants after their caregivers did, and this appeared to be independent of whether infants had seen the plant before. Second, infants systematically engaged in some of the same types of olfactory and touch behaviours their caregiver displayed towards plants. Finally, infants whose caregivers were given more information about the plants in the study showed fewer touch behaviours, but no difference in olfactory behaviours. These findings bolster the previous laboratory studies of plant learning early in life, highlighting the importance of olfactory behaviours, and underscoring the benefits of using ecological observations to explore unique aspects of human development.     

Do common elements predict class merger: A test of Sidman's theory of equivalence

The study presented here investigated the effect of common and uncommon elements on class merger as predicted by Sidman in his reconceptualization of stimulus equivalence suggesting that common elements among contingencies can facilitate emergent performances (1994, 1997, 2000). Eight adult participants were exposed to a procedure that arranged for stimulus–reinforcer correlations in Phase 1 and response–reinforcer correlations in Phase 2 of a 3-phase study. In the common element group, the visual images serving as reinforcers were the same in Phase 1 and Phase 2. In the uncommon elements group, the images serving as reinforcers were different in Phases 1 and 2. In Phase 3, participants were given an opportunity to respond but no feedback was programmed. The results showed that participants' responding was well differentiated in the common element group and undifferentiated in the uncommon elements group. These results are predicted by Sidman's revised formulation of the provenance and scope of equivalence relations. Specifically, these data support Sidman's (1994, 1997, 2000) suggestion that elements of a contingency enter into an equivalence class and common elements among contingencies are sufficient to produce class mergers. The findings highlight an emergent simple discrimination and raise some interesting considerations about the definition of equivalence under the new formulation.     

高中生的亲子沟通质量对情绪性刺激注意偏向的影响

为了探讨高中生亲子沟通质量对情绪性刺激注意偏向的影响,实验一采用亲子沟通量表,筛选出亲子沟通高分组和低分组,两组被试参加点探测任务,要求被试迅速判断情绪性图片出现后呈现的圆点的位置。实验为2（组别：高亲子沟通组、低亲子沟通组）×2（情绪类型：负性和正性）×2（探测点位置一致性：一致、不一致）的混合实验设计。结果发现,负性和正性刺激的不一致条件反应时均显著短于一致条件的反应时。实验二采用事件相关电位（ERP）记录了情绪性图片诱发的信号反应。结果发现,亲子沟通高分组对负性刺激所诱发的注意指向和集中（P2成分）及选择和巩固（P3成分）显著高于低分组。以上结果表明,亲子沟通较好,在注意早期定向和选择中会对负性情绪刺激产生注意偏向。亲子沟通较差,则对情绪性的刺激没有明显的偏向性,类似于“漠不关心”的状态。     

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”。

Subjective power and emotions in everyday interpersonal interactions: Counterparts' constrictive posture as moderator

Power is one of the vital components embedded within interpersonal interactions, but few studies have studied it in everyday life context. This experience sampling study examined the associations of subjective power with emotional well-being and investigated the moderating effects of counterpart' postures in the associations. Our results demonstrated that individuals reported higher positive emotions and lower negative emotions when they perceived higher subjective power. Their positive emotions were positively correlated with counterparts' expansive postures while negative emotions were positively correlated with counterparts' constrictive postures. The subjective power-negative emotion associations were stronger when counterparts displayed higher level of constrictive posture. Our findings provide an evidence base for a comprehensive understanding on the role of subjective power and perception of counterparts' power-related posture in dyadic communications in emotional well-being.     

Does texting interrupt imitation learning in 19-month-old infants?

Observed disruptions to parent-child interactions during parental media use, such as texting, have been termed technoference. For example, when a language learning interaction was disrupted by a phone call, toddlers were less likely to acquire the word. Other studies demonstrated that parents often exhibit a still face while silently reading information on their cell phones. In the present study, the effect of a text interruption on infant imitation learning was examined. Parents demonstrated three target actions to their infants and then infants were given the opportunity to repeat those interactions. The actions were demonstrated four times. Text interruptions occurred before or between demonstrations. Performance of these groups was compared to a baseline control group where the infant did not see a demonstration of the target actions and a no-interruption group where the parents demonstrated the target actions four times without interruption. Parents were randomly assigned to three conditions, interruption-first condition, one-interruption condition, or three-interruptions condition. Infant behavior was measured during the interruptions. Across text interruption groups parents exhibited high levels of still face during the interruptions (77 %). However, infants in all 3 interruption groups performed significantly above the baseline control indicating learning despite the interruptions. Higher reported maternal reliance on the smartphone was related to poorer imitation performance overall. In contrast, when parents reported that they found it easier to multi-task infant imitation rates were higher. These findings indicate that infants can learn under conditions of brief technoference and that individual differences in family media ecology are associated with learning.
