Talker adaptation in speech perception: adjusting the signal or the representations?

Past research has established that listeners can accommodate a wide range of talkers in understanding language. How this adjustment operates, however, is a matter of debate. Here, listeners were exposed to spoken words from a speaker of an American English dialect in which the vowel /ae/ is raised before /g/, but not before /k/. Results from two experiments showed that listeners' identification of /k/-final words like back (which are unaffected by the dialect) was facilitated by prior exposure to their dialect-affected /g/-final counterparts, e.g., bag. This facilitation occurred because the competition between interpretations, e.g., bag or back, while hearing the initial portion of the input [bae], was mitigated by the reduced probability for the input to correspond to bag as produced by this talker. Thus, adaptation to an accent is not just a matter of adjusting the speech signal as it is being heard; adaptation involves dynamic adjustment of the representations stored in the lexicon, according to the characteristics of the speaker or the context.     

Working memory and inhibitory control across the life span: Intrusion errors in the Reading Span Test

The aim of this study was to examine to what extent inhibitory control and working memory capacity are related across the life span. Intrusion errors committed by children and younger and older adults were investigated in two versions of the Reading Span Test. In Experiment 1, a mixed Reading Span Test with items of various list lengths was administered. Older adults and children recalled fewer correct words and produced more intrusions than did young adults. Also, age-related differences were found in the type of intrusions committed. In Experiment 2, an adaptive Reading Span Test was administered, in which the list length of items was adapted to each individual’s working memory capacity. Age groups differed neither on correct recall nor on the rate of intrusions, but they differed on the type of intrusions. Altogether, these findings indicate that the availability of attentional resources influences the efficiency of inhibition across the life span.     

Are young children's drawings canonically biased?

In a between-subjects design, 4- to 6-year-olds were asked to draw from three-dimensional (3D) models, two-and-a-half-dimensional (212D) models with or without depth cues, or two-dimensional (2D) models of a familiar object (a saucepan) in noncanonical orientations (handle at the back or at the front). Results showed that canonical errors were produced mainly by the youngest children in the 3D models copying condition. A large proportion of errors did not, however, reflect biases toward the participants' "own" view of the object; rather, these errors reflected biases toward their "best" view of the object. Drawing from models having fewer than three dimensions resulted in a significant increase in view-specific productions in all children for the back orientation. When a more complex front orientation of the object was proposed, sensitivity to model type developed gradually with age. Results are discussed in terms of the flexibility of the mental model that mediates between children's perception of a model object and the depiction decisions.     

Amplification of attentional blink by distress‐related facial expressions: Relationships with alexithymia and affectivity

The present studies aimed to analyse the modulatory effect of distressing facial expressions on attention processing. The attentional blink (AB) paradigm is one of the most widely used paradigms for studying temporal attention, and is increasingly applied to study the temporal dynamics of emotion processing. The aims of this study were to investigate how identifying fear and pain facial expressions (Study 1) and fear and anger facial expressions (Study 2) would influence the detection of subsequent stimuli presented within short time intervals, and to assess the moderating influence of alexithymia and affectivity on this effect. It has been suggested that high alexithymia scorers need more attentional resources to process distressing facial expressions and that negative affectivity increases the AB. We showed that fear, anger and pain produced an AB and that alexithymia moderated it such that difficulty in describing feelings (Study 1) and externally oriented thinking (Study 2) were associated with higher interference after the processing of fear and anger at short time presentations. These studies provide evidence that distressing facial expressions modulate the attentional processing at short time intervals and that alexithymia influences the early attentional processing of fear and anger expressions. Controlling for state affect did not change these conclusions.     

Initial Implementation of the ARC Framework in Juvenile Justice Settings

Virtually all youth in detention have been exposed at least one traumatic event in their family system or in the community, and a vast majority have experienced cumulative traumatic events that led to major dysregulated states. Building on several seminal works on trauma-informed juvenile justice programs and on implementation research, this theoretical research-based paper aims to describe the preparation stage for implementation of the Attachment, Self-Regulation, and Competency framework (ARC) to a population of youth in detention. The ARC framework is well-suited to meet the complex needs of young offenders by focusing on building blocks that promote resiliency, including caregiver affect management and attunement, affect identification and modulation, and executive functions and self-identity. Based on this extensive preparation stage and a case illustration, recommendations and best practice protocols for making a shift towards a trauma-informed youth justice system are highlighted.     

The case of the drunken sailor: On the generalisable wrongness of harmful transgressions

There is a widespread conviction that people distinguish two kinds of acts: on the one hand, acts that are generalisably wrong because they go against universal principles of harm, justice, or rights; on the other hand, acts that are variably right or wrong depending on the social context. In this paper we criticise existing methods that measure generalisability. We report new findings indicating that a modification of generalisability measures is in order. We discuss our findings in light of recent criticisms of moral/conventional research.     

Effects of motor action on affective preferences in autism spectrum disorders: different influences of embodiment

In the embodied cognition framework, sensory, motor and emotional experiences are encoded along with sensorimotor cues from the context in which information was acquired. As such, representations retain an initial imprint of the manner in which information was acquired. The current study reports results indicating a lack of embodiment effects in ASD and, further, an association between embodiment differences and ASD symptomatology. The current results are consistent with an embodied account of ASD that goes beyond social experiences and could be driven by subtle deficits in sensorimotor coordination.     

Analyzing the convergent and discriminant validity of states and traits: development and applications of multimethod latent state-trait models

The analysis of convergent and discriminant validity is an integral part of the construct validation process. Models for analyzing the convergent and discriminant validity have typically been developed for cross-sectional data. There exist, however, only a few approaches for longitudinal data that can be applied for analyzing the construct validity of fluctuating states. In this article, the authors show how models of latent state-trait theory can be combined with models of multitrait-multimethod analysis to develop a model that allows for analyzing convergent and discriminant validity in time: the multimethod latent state-trait model. The model allows for identifying different sources of variance (trait consistency, trait-method specificity, occasion-specific consistency, occasion-specific method specificity, and unreliability). It is applied to the repeated measurement of depression and anxiety in children, which was assessed by self and teacher reports (N = 375). The application shows that the proposed models fit the data well and allow a deeper understanding of method effects in clinical assessment.     

Influence of obstetrical events on satisfaction and anxiety during childbirth: a prospective longitudinal study

The aim of this study was to investigate the feelings of anxiety and satisfaction among 79 primiparas who had uncomplicated pregnancies, at the time of hospital admission and after birth, considering the mode of delivery, analgesia, and pain levels. Questionnaires were completed at admission to the hospital and two months after delivery, using the State-Trait Anxiety Inventory (STAI) state scale and the Labour Agentry Scale. The mean (SD) STAI state score was higher at admission (36.7 (10.7)) than 4 months after childbirth (32.1 (9.7)) (paired Student’s t-test, t = 2.93; df = 78; p = .004). However, the postnatal anxiety was not associated with the mode of delivery, epidural or pain. Regarding the satisfaction with the expectations of control during childbirth, the mean (SD) score was higher before childbirth (166.0 (21.8)) than after (157.5 (33.5)) (paired Student’s t-test, t = ?2.28; df = 77; p = .03). The satisfaction with the childbirth experience was significantly associated with the expectations of childbirth and the mode of delivery, but not with analgesia or pain. The postnatal anxiety was associated with physical health, pain and the Edinburgh Postnatal Depression Scale score during the postpartum period. It is important to consider the temporality of perinatal anxiety in order to understand its causes. Our results indicate that the experience of childbirth was predicted in this sample by the antenatal expectations and delivery outcomes.
