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.     

From criticism to approval: A reconsideration of Ji’s Yogācāra position on Madhyamaka

Madhyamaka and Yogācāra are two Mahāyāna schools which have distinct systems. In the seventh century East Asia, the doctrinal distinction between the two schools was received as doctrinal contrast in the polemic circumstance of Emptiness-Existence (C. kongyou 空有) controversy. In this context, Ji 基 (632–682), the putative founder of East Asian Yogācāra school, has been normally considered by scholars to have advocated ‘Existence’ (viz., Yogācāra) in opposition to ‘Emptiness’ (viz., Madhyamaka). It is problematic, however, to brand Ji’s Yogācāra position simply as anti-Madhyamaka. Although Ji evidently expresses evident criticism on such a Madhyamaka exegete as Bhāvaviveka (ca. 500–570) in some of his works, he also describes Bhāvaviveka in an amicable or even respective way in other works. By analyzing Ji’s extant works, this article argues that Ji’s scholastic attitude toward Madhyamaka changed from criticism to approval.     

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.     

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.     

Pets as safe havens and secure bases: The moderating role of pet attachment orientations

We examined the extent to which a pet functions as an attachment figure. In Study 1, 165 pet owners performed a goal exploration task, assessing the number of life goals generated and confidence in goal attainment. In Study 2, 120 pet owners performed a distress-eliciting task while assessing blood pressure. In both studies, participants were divided into three conditions: pet physical presence, pet cognitive presence, and no pet presence. As compared to no pet presence, physical or cognitive pet presence increased the number of life goals generated and self-confidence in goal attainment and reduced blood pressure during the distress-eliciting task. The findings confirm the ability of a pet to provide a safe-haven and a secure-base and the moderating role of attachment insecurities.     

Dielectric and spectrometric investigations of binary mixtures of tetrahydrofuran with propionic acid

The static permittivity (ε_m ) and the permittivity at the high-frequency limit (ε_∞m ) of a binary mixture of propionic acid with tetrahydrofuran (THF) have been determined for different concentrations at temperatures of 303, 308, 313, and 318 K. The data have been used to compute the Kirkwood correlation factor, the excess permittivity, and the excess free-energy of the mixtures. The Kirkwood correlation factor is found to increase with increasing THF concentration. The mixture exhibited positive values of the excess permittivity and negative values of the excess free-energy of mixing, respectively. UV-Vis and FT-IR spectral measurements have also been carried out. The observed bathochromism and hypochromism in the UV-Vis spectra have been explained in terms of complex formation and ordering of dipoles of the complex. The FT-IR spectrum of the mixture shows considerable shifts in the positions of some of the absorption bands, indicating extensive hydrogen bonding between solute and solvent molecules.
