Mothers' Impact on Daughters' Cardiovascular Reactivity in a High‐Threat Context: An Immersive Virtual Environment Study

Applying Attachment Theory, research on confirmation, the Entropy Model of Uncertainty, and the Biopsychosocial Model of Challenge and Threat, this investigation examined the role of mothers' communication on adolescents' cardiovascular response to threat. An experimental design allowed for the manipulation of maternal response to daughters experiencing a rapidly approaching wildfire in an immersive virtual environment. Results revealed complexities in the relative benefits of maternal vocalic presence during high‐threat situation, with the mother's history of confirming feedback playing an important role in daughters' cardiovascular response. Implications for knowledge are addressed and methodological possibilities of using immersive virtual environments are noted.     

Do people reason rationally about causally related events? Markov violations,weak inferences,and failures of explaining away

Making judgments by relying on beliefs about the causal relationships between events is a fundamental capacity of everyday cognition. In the last decade, Causal Bayesian Networks have been proposed as a framework for modeling causal reasoning. Two experiments were conducted to provide comprehensive data sets with which to evaluate a variety of different types of judgments in comparison to the standard Bayesian networks calculations. Participants were introduced to a fictional system of three events and observed a set of learning trials that instantiated the multivariate distribution relating the three variables. We tested inferences on chains X₁ → Y → X₂, common cause structures X₁ ← Y → X₂, and common effect structures X₁ → Y ← X₂, on binary and numerical variables, and with high and intermediate causal strengths. We tested transitive inferences, inferences when one variable is irrelevant because it is blocked by an intervening variable (Markov Assumption), inferences from two variables to a middle variable, and inferences about the presence of one cause when the alternative cause was known to have occurred (the normative “explaining away” pattern). Compared to the normative account, in general, when the judgments should change, they change in the normative direction. However, we also discuss a few persistent violations of the standard normative model. In addition, we evaluate the relative success of 12 theoretical explanations for these deviations.     

Roost-mate communication in adult Indian false vampire bats (Megaderma lyra): an indication of individuality in temporal and spectral pattern

The remarkable cognitive abilities of bats indicate that they may recognise particular conspecifics. Because of their highly developed auditory system, it is obvious that vocalisations of bats may give information about the individual emitting them. In a field study of the social behaviour in the Indian false vampire bat (Megaderma lyra), two different types of vocalisation were recorded and analysed. The bats emitted these vocalisations only while aggregating with conspecifics inside the day roost. The “landing strophe” consisted of a number of brief multiharmonic downward frequency-modulated (FM_down) sounds which levelled off as a constant frequency (CF), and the “clatter strophe” was composed of a number of multiharmonic FM_down sounds which became shallow at the end as a short CF. The sounds of the landing strophe and the ¶clatter strophe differed in repetition rate, duration, harmonic components and frequency. Time pattern and peak frequency of the two sound types differed highly significantly between single, unidentified bats. The sounds were inter-individually distinct when the three parameters were combined as an acoustical space. Therefore, these vocalisations might be used for individual recognition in adult bats.     

Depressive Symptoms,Criticism, and Counter‐Criticism in Marital Interactions

Although people with depressive symptoms face criticism, hostility, and rejection in their close relationships, we do not know how they respond. Following interpersonal theories of depression, it might be expected that depressive symptoms would be associated with a tendency to receive and also to express criticism toward one's spouse, and that at least some of this criticism would be a contingent response to criticism received (i.e., “counter‐criticism”). However, other research has determined that depressive symptoms/behaviors suppress partner criticism, suggesting that depressed people might respond to partner criticism similarly, by subsequently expressing less criticism. In a sample of 112 married couples, partial correlations, regressions, and Actor‐Partner Interdependence Modeling indicated that lower criticism and counter‐criticism expression during a laboratory marital interaction task was associated with higher depressive symptoms, especially when such individuals were clinically depressed. Furthermore, during a separate and private Five‐Minute Speech Sample, lower criticism by partners was associated with higher depressive symptoms, especially when those who chose the interaction topic were also clinically depressed. All analyses controlled for relationship adjustment. These results suggest that spouses with higher depressive symptoms and clinical depression diagnoses may be suppressing otherwise ordinary criticism expression toward their nondepressed partners; furthermore, nondepressed partners of depressed people are especially likely to display less criticism toward their spouse in a private task.     

Marital commitment,communication and marital satisfaction: An analysis based on actor–partner interdependence model

Marital commitment and satisfaction are known to be closely related, but only limited research has examined the asymmetric interaction patterns between spouses. In this paper, the authors study 400 Chinese couples and find that communication mediates the relationship between marital commitment and marital satisfaction. Using the actor–partner interdependence model, they find that wives and husbands show asymmetric associations for marital commitment, communication and satisfaction. Specifically, compared with husbands, wives are more attuned to the path from marital commitment to marital satisfaction via communication. Implications and limitations are discussed.     

多维项目反应理论补偿性模型参数估计:基于广义回归神经网络集合

运用广义回归神经网络(GRNN)方法对小样本多维项目反应理论(MIRT)补偿性模型的项目参数进行估计,尝试解决传统参数估计方法样本数量要求较大的问题。MIRT双参数Logistic补偿模型被设置为二级计分的二维模型。首先,模拟二维能力参数、项目参数值与考生作答矩阵。其次,把通过主成分分析得到的前两个因子在每个题目上的载荷作为区分度的初始值以及题目通过率作为难度的初始值,这两个指标的初始值作为神经网络的输入。集成100个神经网络,其输出值的均值作为MIRT的项目参数估计值。最后,设置2×2种(能力相关水平:0.3和0.7; 两种估计方法:GRNN和MCMC方法)实验处理,对GRNN和MCMC估计方法的返真性进行比较。结果表明,小样本的情况下,基于GRNN集成方法的参数估计结果优于MCMC方法。     

L’animation des collectifs visant la prévention des RPS : étude d’un processus d’intervention en milieu hospitalier

This article presents an intervention process aiming at the prevention of PSRs: diagnosis followed by the development of an action plan produced during three collective meetings. Each meeting is based on a particular type of animation (with reminders focused on causes, with reminders on the solutions and enriched with the psychologist's expertise animations). The stake is to characterise each of these animation methods and to study their impact on the collective activity. The study proceeds in analysis of linguistic production produced. The intervention proceeded in a hospital setting. The development of the action plan implied a collective of 8 to 10 agents who met three times. The results show in particular that (1) style of speech is argumentative whatever either in the form of animation, (2) nature reminders and the issue of the meeting have an impact on the functional structure of the meetings and (3) reminders on the solutions lead the evocation of factual causes so that reminders focused on causes lead to identify more general causes.     

Marital Expectations in Strong African American Marriages

The current exploratory study utilized a family strengths framework to identify marital expectations in 39 strong African American heterosexual marriages. Couples reflected on their marital expectations over their 10 or more years of marriage. Three themes emerged through qualitative analysis and the participants' own words were used in the presentation of the themes. African Americans indicated that there was growth in marital expectations over time, with marital expectations often beginning with unrealistic expectations that grew into more realistic expectations as their marriages progressed. Participants also indicated that core expectations in strong African American marriages included open communication, congruent values, and positive treatment of spouse. Finally, participants explained there is an “I” in marriage as they discussed the importance of autonomy within their marital relationships. Results are discussed in association with existing research and theory.     

Selling Innovations Like Soap: The Interactive Systems Framework and Social Marketing

Despite the popularity and noted utility of Wandersman and colleagues' (2008) Interactive Systems Framework, the literature currently provides a primary focus on delivery organizations’ and supportive stakeholders’ capacities and strategies to implement innovations, presenting a critical gap in understanding. Unfortunately, reflective of a larger void in community dissemination and implementation efforts, there is a more limited focus on the dissemination of innovations. This paper presents the social marketing literature as a supplement to the Prevention Synthesis and Translation System (PSTS), the system responsible for dissemination. The study and practice of innovation synthesis and translation is examined in the literature; and based on the conclusions drawn, social marketing theory is used to provide a systematic approach to improving dissemination within the Interactive Systems Framework. Specifically, three gaps related to the PSTS are identified in the literature that align with and can be filled using social marketing. Social marketing is defined and presented as a supplement by providing theory and practices, within a systems context, for effectively communicating and influencing change. By blending social marketing with the Interactive Systems Framework, the aim is to improve the understanding of strategic communication and its role in the effective dissemination, and subsequent implementation, of innovations.     

Les aspects pragmatiques de la communication chez les primates

Pragmatics is about how individuals use their inventory of semiotic devices, the strategic choices they make, in particular acts of communication. An interesting question is the degree to which other animal species, especially our nearest primate relatives, employ pragmatic strategies in their vocal and gestural communication. Based on a review of the evidence, it is concluded in this essay that primate communication displays almost none of the pragmatic dimensions that characterize human linguistic communication. The most fundamental reason is that nonhuman animal communication does not really take place on the mental or intersubjective plane at all. It is directed at the behavior and emotional states of others, not at their attentional or mental states.
