Statistical learning of multiple speech streams: A challenge for monolingual infants

Language acquisition depends on the ability to detect and track the distributional properties of speech. Successful acquisition also necessitates detecting changes in those properties, which can occur when the learner encounters different speakers, topics, dialects, or languages. When encountering multiple speech streams with different underlying statistics but overlapping features, how do infants keep track of the properties of each speech stream separately? In four experiments, we tested whether 8‐month‐old monolingual infants (N = 144) can track the underlying statistics of two artificial speech streams that share a portion of their syllables. We first presented each stream individually. We then presented the two speech streams in sequence, without contextual cues signaling the different speech streams, and subsequently added pitch and accent cues to help learners track each stream separately. The results reveal that monolingual infants experience difficulty tracking the statistical regularities in two speech streams presented sequentially, even when provided with contextual cues intended to facilitate separation of the speech streams. We discuss the implications of our findings for understanding how infants learn and separate the input when confronted with multiple statistical structures.     

Stroop interference is a composite phenomenon: Evidence from distinct developmental trajectories of its components

Only one previous developmental study of Stroop task performance (Schiller, 1966) has controlled for differences in processing speed that exist both within and between age groups. Therefore, the question of whether the early developmental change in the magnitude of Stroop interference actually persists after controlling for processing speed needs further investigation; work that is further motivated by the possibility that any remaining differences would be caused by process(es) other than processing speed. Analysis of data from two experiments revealed that, even after controlling for processing speed using z‐transformed reaction times, early developmental change persists such that the magnitude of overall Stroop interference is larger in 3rd‐ and 5th graders as compared to 1st graders. This pattern indicates that the magnitude of overall Stroop interference peaks after 2 or 3 years of reading practice (Schadler & Thissen, 1981). Furthermore, this peak is shown to be due to distinct components of Stroop interference (resulting from specific conflicts) progressively falling into place. Experiment 2 revealed that the change in the magnitude of Stroop interference specifically results from joint contributions of task, semantic and response conflicts in 3rd‐ and 5th graders as compared to a sole contribution of task conflict in 1st graders. The specific developmental trajectories of different conflicts presented in the present work provide unique evidence for multiple loci of Stroop interference in the processing stream (respectively task, semantic and response conflict) as opposed to a single (i.e. response) locus predicted by historically – favored response competition accounts.     

Complementary teaching practices: Ignatian pedagogy and Buddhist‐inspired compassion meditation

While scholarly discussions on Jesuit education are plentiful, inquiries related to Ignatian pedagogy are rare. This article examines the applications of Ignatian pedagogy by juxtaposing it with the analysis of a Buddhist‐inspired and interdisciplinary contemplation program, Cognitively‐Based Compassion Training® (CBCT®). Drawing from the author's experience in teaching CBCT® at a Jesuit University, this article explores how CBCT® aligns with the Ignatian Pedagogical Paradigm's five elements: context, experience, reflection, action, and evaluation. This study uses psychometrical measurements, such as the Compassionate Love for Humanity Scale, to document how my interdisciplinary approach may enhance participants' emotional well‐being and widen their ethical concerns. As these outcomes are inherently cross‐disciplinary and include intellectual and affective dimensions, they cannot be achieved through a single field. Building a bridge between the Ignatian Pedagogical Paradigm and CBCT® provides a successful strategy for the educational objectives of developing the whole person and forming a compassionate character.     

Examining the narrative roles in suicide notes

The present study examines suicide notes, using a sample of suicide notes from published corpora (N = 50), combined with a sample of recent suicide notes from a suicide website (N = 50). The present study proposes a model of differentiation in completed suicides. The characteristics of the suicide notes were analysed using a content dictionary developed by Giles in 2007, and the data subjected to smallest space analysis. Four themes of suicide completer were discovered: Egoistic Victim, Anomic Hero, Altruistic Professional and Fatalistic Revenger. The implications of these findings and the potential use in therapy work with suicide survivors and those with suicidal ideation are discussed, as well as suggestions for the direction of future research.     

Toward a social psychophysiology of vagally mediated heart rate variability: Concepts and methods in self‐regulation,emotion, and interpersonal processes

Theory and research on self‐regulation, emotional adjustment, and interpersonal processes focus increasingly on parasympathetic functioning, using measures of vagally mediated heart rate variability (vmHRV) or respiratory sinus arrhythmia (RSA). This review describes models of vmHRV in these areas, and issues in measurement and analysis. We propose a framework organizing theory and research as examining (a) vmHRV as an individual difference or a situational response, and (b) resting, reactive, or recovery levels. Evidence supports interpretation of individual differences in resting vmHRV as a broad biomarker for adaptive functioning, but its specificity and underlying mechanisms require elaboration. Individual differences in vagal reactivity (i.e., trait‐like differences in vmHRV decreases during challenge or stress) are less commonly studied in adults and results are mixed. Many stressors and challenges evoke temporary decreases in vmHRV, and in some research self‐regulatory effort evokes increases. In a smaller literature, positive interpersonal experiences and some restorative processes increase resting vmHRV, whereas depletion of self‐regulatory capacity through related effort decreases it. Greater attention to conceptual distinctions regarding vmHRV constructs and several methodological issues will strengthen future research. Importantly, researchers should exercise caution in equating vmHRV with specific psychosocial constructs, especially in the absence of converging assessments and precise experimental manipulations.     

Exemplarist Environmental Ethics

This article argues that environmental ethics can deemphasize environmental problem‐solving in preference for a more exemplarist mode. This mode will renarrate what we admire in those we have long admired, in order to make them resonate with contemporary ethical needs. First, I outline a method problem that arose for me in ethnographic fieldwork, a problem that I call, far too reductively, “solution thinking.” Second, I relate that method problem to movements against “quandary ethics” in ethical theory more broadly. Third, I discuss some interpretive work I am engaged in about Henry David Thoreau and how it bears on the methodological issues my fieldwork raised. I argue that some of the most important icons of right relation to environment, especially Francis of Assisi and Thoreau, should be envisioned as far more politically invested than they usually are. They demonstrate to scholars of religious ethics that an exemplarist ethic focused on character need not neglect politics.     

Exploring New and Renewed Eco‐Spiritualities

This essay discusses five recent books, written in French, that contribute to refection in environmental ethics. Francophone literature on the topic is marked by resonant and divergent concerns, and rooted in a geography, politics, and history different from North America and marked by distinctive lines of intellectual influence. Jean‐Claude Eslin proposes recovering ecological resources from the Christian tradition and also suggests imagining new images of God: notably, God as pilote rather than artisan. Dominique Bourg takes a multi‐disciplinary approach that emphasizes the spiritual conditions for relating to the world ecologically and economically; he argues for sobriété (austerity) as a spiritual disposition and an economic model. Baptiste Morizot develops diplomacy as an ethical, political, and spiritual model for cohabiting with wolves, whose return to the French countryside has been highly controversial. Nastassja Martin offers an anthropological study of the indigenous Gwich’in community of Fort Yukon, Alaska that accentuates the mix of Protestant missional influences and Gwich’in spiritual affirmations and practices at play in their relationship to the nonhuman world. Attending to this literature may helpfully decenter anglophone debates and enrich their conceptual vocabulary.
