The Role of Speech-Gesture Synchrony in Clipping Words From the Speech Stream: Evidence From Infant Pupil Responses

How do young infants discover that a segment of the sound stream refers to a particular aspect of the visual world around them? Speakers do not enunciate each word separately, even to infants; rather, whattheysayrunstogether. To relate an object (say, an apple) to its referent, infants must notice the interactant's target of attention (the apple) and at the same time single out the word that refers to it as the other person speaks (Lookattheapple!). We contend that caregivers through their actions assist by directing and educating an infant's attention, particularly through the use of a show gesture. The onset/offset, rhythm, tempo, and duration of these show gestures are synchronous with the saying of the words referring to the target objects. Our prior research using eye tracking found that show gestures lead an infant to look at the object presented as the word for it is uttered and that show gestures facilitate word learning. In this research we tested the hypothesis that show gestures also lead to enhanced attentional processing as measured through pupil dilation. Comparing pupil diameters while words were introduced with a show, static, or asynchronous dynamic gesture, we found that pupil dilation occurred for the show gesture condition and was positively correlated with word learning.     

Using Vignette Methodology as a Tool for Exploring Cultural Identity Positions of Language Brokers

This article examines how vignette methodology can aid understanding of cultural identity. This is demonstrated through a study of child language brokers, wherein a child is engaged in the cultural contexts of both the host culture and the home culture and must therefore negotiate new cultural identities. Participants were young people aged 15 to 18 years; some of them were brokers, others were not. Drawing on notions of adequacy and inadequacy, visibility and invisibility, theoretical ideas around cultural identity theory and dialogical self-theory can provide an understanding of how the young people moved through different (often conflicting) identity positions.     

Prior Publication and Redundancy in Contemporary Science: Are Authors and Editors at the Crossroads?

We discuss prior publication and redundancy in contemporary science in the context of changing perceptions of originality in the communication of research results. These perceptions have been changing in the publication realm, particularly in the last 15 years. Presenting a brief overview of the literature, we address some of the conflicts that are likely to arise between authors and editors. We illustrate our approach with conference presentations that are later published as journal articles and focus on a recent retraction of an article that had been previously published as a conference proceedings. Although we do not make definitive pronouncements on the matter—as many concepts are evolving—we do argue that conference papers that contain sufficient details for others to attempt a replication and are indexed in scientific databases such as PubMed, challenge some currently held assumptions of prior publication and originality in the sciences. Our view is that these important issues are in need of further clarification and harmonization within the science publishing community. This need is more evident when we consider current notions of research integrity when it comes to communication to peers. Revisiting long-standing views about what constitutes prior publication and developing a clearer set of guidelines for authors and editors to follow should reduce conflicts in the research environment, which already exerts considerable pressure, especially on newcomers in academia. However, while clearer guidelines are timely, developing them is only part of the challenge. The present times seem to call for deeper changes in the research and publication systems.     

What's up? Emotion-specific activation of vertical space during language processing

The relationship between language processing and vertical space has been shown for various groups of words including valence words, implicit location words, and words referring to religious concepts. However, it remains unclear whether these are single phenomena or whether there is an underlying common mechanism. Here, we show that the evaluation of word valence interacts with motor responses in the vertical dimension, with positive (negative) evaluations facilitating upward (downward) responses. When valence evaluation was not required, implicit location words (e.g., bird, shoe) influenced motor responses whereas valence words (e.g., kiss, hate) did not. Importantly, a subset of specific emotional valence words that are commonly associated with particular bodily postures (e.g., proud → upright; sad → slouched) did automatically influence motor responses. Together, this suggests that while the vertical spatial dimension is not directly activated by word valence, it is activated when processing words referring to emotional states with stereotypical bodily-postures. These results provide strong evidence that the activation of spatial associations during language processing is experience-specific in nature and cannot be explained with reference to a general mapping between all valence words and space (i.e., all positive and negative words generally relate to spatial processing). These findings support the experiential view of language comprehension, suggesting that the automatic reactivation of bodily experiences is limited to word groups referring to emotions or entities directly associated with spatial experiences (e.g., posture or location in the world).     

Pain and Bodily Care: Whose Body Matters?

Pain is unpleasant. It is something that one avoids as much as possible. One might then claim that one wants to avoid pain because one cares about one's body. On this view, individuals who do not experience pain as unpleasant and to be avoided, like patients with pain asymbolia, do not care about their body. This conception of pain has been recently defended by Bain [2014 Bain, D. 2014. Pains That Don't Hurt, Australasian Journal of Philosophy 92/2: 305–20.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]] and Klein [forthcoming Klein, C. forthcoming. What Pain Asymbolia Really Shows, Mind. [Google Scholar]]. In their view, one needs to care about one's body for pain to have motivational force. But does one need to care about one's body qua one's own? Or does one merely need to care about the body that happens to be one's own? In this paper, I will consider various interpretations of the notion of bodily care, in light of a series of pathological cases in which patients report pain in a body part that they do not experience as their own. These cases are problematic if one adopts a first-personal interpretation of bodily care, according to which pain requires one to care about what is represented as one's own body. The objection can run as follows. If the patients experience the body part as alien, then they should not care about it. Therefore, they should be similar to patients with pain asymbolia. But they are not. Hence, bodily care is not necessary to pain. To resist this conclusion, one can try to revise the interpretation of the notion of bodily care and to offer alternative interpretations that are not first-personal. However, I will show that that those alternatives also fail to account for these borderline cases of pain.     

Couple and Family Treatments: Study Quality and Level of Evidence

This paper examines the application of the guidelines for evidence‐based treatments in family therapy developed by Sexton and collaborators to a set of treatment models. These guidelines classify the models using criteria that take into account the distinctive features of couple and family treatments. A two‐step approach was taken: (1) The quality of each of the studies supporting the treatment models was assessed according to a list of ad hoc core criteria; (2) the level of evidence of each treatment model was determined using the guidelines. To reflect the stages of empirical validation present in the literature, nine models were selected: three models each with high, moderate, and low levels of empirical validation, determined by the number of randomized clinical trials (RCTs). The quality ratings highlighted the strengths and limitations of each of the studies that provided evidence backing the treatment models. The classification by level of evidence indicated that four of the models were level III, “evidence‐based” treatments; one was a level II, “evidence‐informed treatment with promising preliminary evidence‐based results”; and four were level I, “evidence‐informed” treatments. Using the guidelines helped identify treatments that are solid in terms of not only the number of RCTs but also the quality of the evidence supporting the efficacy of a given treatment. From a research perspective, this analysis highlighted areas to be addressed before some models can move up to a higher level of evidence. From a clinical perspective, the guidelines can help identify the models whose studies have produced clinically relevant results.     

The DAPP–SF as a Screener for Personality Disorder in a Forensic Setting

Studies on the Dimensional Assessment of Personality Pathology–Short Form (DAPP–SF) have shown its ability to identify treatment-seeking patients with personality disorders. This study focuses on its screening potential for personality disorder in 89 criminal suspects (77 men, 12 women; M age = 37.0 years) undergoing residential pretrial psychological assessments in a high-security setting. It was expected that Structured Interview for DSM–IV Personality (SIDP–IV) criteria met for personality disorder(s) would be associated with higher DAPP–SF scores. A floor effect was found in DAPP–SF scores: The forensic population reported less personality pathology than the general population. Only moderate associations between DAPP–SF and SIDP–IV outcome were found. Receiver operating characteristic analysis showed that some DAPP–SF subscales did not exceed chance level in their ability to screen for personality disorders. It is concluded that the DAPP–SF has limited usefulness as a screener for personality disorders in a forensic pretrial setting. Alternative forensic screening instruments are presented.
