Prelinguistic Infants, but Not Chimpanzees, Communicate About Absent Entities

ABSTRACT— One of the defining features of human language is displacement , the ability to make reference to absent entities. Here we show that prelinguistic, 12-month-old infants already can use a nonverbal pointing gesture to make reference to absent entities. We also show that chimpanzees—who can point for things they want humans to give them—do not point to refer to absent entities in the same way. These results demonstrate that the ability to communicate about absent but mutually known entities depends not on language, but rather on deeper social-cognitive skills that make acts of linguistic reference possible in the first place. These nonlinguistic skills for displaced reference emerged apparently only after humans' divergence from great apes some 6 million years ago.     

Adult brains don't fully overcome biases that lead to incorrect performance during cognitive development: an fMRI study in young adults completing a Piaget‐like task

A current issue in developmental science is that greater continuity in cognition between children and adults may exist than is usually appreciated in Piaget‐like (stages or ‘staircase’) models. This phenomenon has been demonstrated at the behavioural level, but never at the brain level. Here we show with functional magnetic resonance imaging (fMRI), for the first time, that adult brains do not fully overcome the biases of childhood. More specifically, the aim of this fMRI study was to evaluate whether the perceptual bias that leads to incorrect performance during cognitive development in a Piaget‐like task is still a bias in the adult brain and hence requires an executive network to overcome it. Here, we compared two numerical‐judgment tasks, one being a Piaget‐like task with number–length interference (called ‘INT’) and the other being a control task with number–length covariation (‘COV’). We also used a colour‐detection task to control for stimuli numerosity, spatial distribution, and frequency. Our behavioural results confirmed that INT remains a difficult task for young adults. Indeed, response times were significantly higher in INT than in COV. Moreover, we observed that only in INT did response times increase linearly as a function of the number of items. The fMRI results indicate that the brain network common to INT and COV shows a large rightward functional asymmetry, emphasizing the visuospatial nature of these two tasks. When INT was compared with COV, activations were found within a right frontal network, including the pre‐supplementary motor area, the anterior cingulate cortex, and the middle frontal gyrus, which probably reflect detection of the number/length conflict and inhibition of the ‘length‐equals‐number’ response strategy. Finally, activations related to visuospatial and quantitative processing, enhanced or specifically recruited in the Piaget‐like task, were found in bilateral posterior areas.     

Changes in cry acoustics and distress ratings while the infant is crying

Acoustics and distress ratings were examined during four minutes of naturally occurring crying from 20 healthy, 1‐month‐old infants. Two listeners made continuous judgements of infant distress during every 10‐s segment of each cry sample. Dysphonation, number of wails, and pause duration were related to distress ratings across the 4 min of crying. Means and variances of ratings and acoustics, and the predictive value of each acoustic variable to ratings, differed in the first and second halves of the samples. Differences in the pattern of results occurred for individual infants. The results highlight the importance of studying the cry as a dynamic acoustic signal that may provide unique information about an individual infant's level of distress.

Aplasic phantoms and the mirror neuron system: An enactive, developmental perspective

Phantom limb experiences demonstrate an unexpected degree of fragility inherent in our self-perceptions. This is perhaps most extreme when congenitally absent limbs are experienced as phantoms. Aplasic phantoms highlight fundamental questions about the physiological bases of self-experience and the ontogeny of a physical, embodied sense of the self. Some of the most intriguing of these questions concern the role of mirror neurons in supporting the development of self–other mappings and hence the emergence of phantom experiences of congenitally absent limbs. In this paper, we will examine the hypothesis that aplasic phantom limb experience is the result of an ontogenetic interplay between body schemas and mirror neuron activity and that this interplay is founded on embedding in a social context. Phantom limb experience has been associated with the persistence of subjective experience of a part of the body after deafferentation through surgical or traumatic removal. We maintain that limited association is inconsistent with the extent to which phantom limb experience is reported by aplasic individuals.

SPECIAL SERIES: Intensive Cognitive-Behavioral Treatments for Child and Adolescent Anxiety Disorders

Cognitive-behavioral treatments are efficacious intervention choices for anxious youth, yet the lack of access to and usage of evidence-based treatments outside of a research context continues to challenge efforts to disseminate and implement such interventions. One potential avenue for reconciling effective care and that most readily accessed by children and their families may be to offer treatment in an intensive format, typically consisting of a more concentrated dose of cognitive-behavioral treatment components. This special series in Cognitive and Behavioral Practice aims to explore the evolution of intensive cognitive-behavioral treatments currently under investigation across a variety of child and adolescent anxiety disorder populations, including specific phobias, obsessive-compulsive disorder, separation anxiety disorder, school refusal, and panic disorder. In addition to delineating the research support to date for intensive cognitive-behavioral treatment among children and adolescents with anxiety disorders, the articles included in this series provide detail on the application of each intensive intervention, highlight innovative treatment elements, and explore clinical and systematic issues unique to an abbreviated treatment format.     

An evaluation of parent preference for prompting procedures

Parent participation in intervention can enhance intervention efficacy and promote generalization of skills across settings. Thus, parents should be trained to implement behavioral interventions. The purpose of the current investigation was to evaluate parent preference for and acceptability of 3 commonly used prompting procedures. We trained parents of children with disabilities to use 3 empirically validated prompting strategies (i.e., least-to-most, most-to-least, and a progressive-prompt delay). Once the parent reached the mastery criteria with each prompting procedure, we evaluated his/her preference for each of the procedures using a concurrent-chains arrangement. We also measured treatment acceptability of all procedures throughout the study. All participants met the mastery criteria for each of the prompting procedures and showed a preference for least-to-most prompting. Results suggest parents' acceptability of procedures prior to training were different than posttraining/post-child practice. In addition, acceptability rating scores obtained at the end of the investigation corresponded to preference of intervention during the concurrent-chains arrangement. The results demonstrate the benefits of objective measures for studying preference for behavioral, skill-acquisition procedures.     

Diversity in practitioners' perspectives on the implementation of the evidence‐based Triple P—Positive Parenting Program

Evidence‐based programs (EBPs) have the potential to improve the well‐being of families and children, but do not necessarily produce the expected outcomes when implemented in real‐world settings. It thus appears essential to consider the factors that can impact the implementation process, especially those related to the practitioners who deliver these programs. This study aimed to identify and describe common patterns in practitioners' experience of the implementation of an EBP. To this end, six focus groups were conducted with 38 practitioners from the health, social and education sectors, 1 year after they had received training in the evidence‐based Triple P—Positive Parenting Program. An in‐depth analysis of the content of these interviews revealed a diversity in the practitioners' experience of the implementation of Triple P. Three distinct types of discourse regarding the implementation process, labelled ‘conviction’, ‘mastering’ and ‘estrangement’ discourse, were identified. Motivational theories were used to understand the interaction between the factors that appeared to be key elements differentiating the discourses in this typology (i.e., practitioners' attitudes, perceived organisational support, self‐efficacy and level of program use). This study highlights the dynamic nature of the implementation process, and shows that a negative initial position towards a new EBP can change over time, given the appropriate organisational conditions.
