Neonatal Imitation: Theory, Experimental Design, and Significance for the Field of Social Cognition

Does Vocalization Increase the Positive Valence of Emotion?

PURPOSE

This study aims to determine if the act of voicing can have an effect on mood.

DESIGN

A within-participant reversal paradigm, where each participant served as their own control.

METHODS

Following a baseline condition, 40 participants (8 male, 32 female, none disclosed as other) underwent three experimental conditions: breathing, articulating, and voicing. After each condition, participants underwent a picture-viewing emotion-induction paradigm using the International Affective Picture System followed by rating their current mood and arousal.

RESULTS

Immediately following the articulating condition, aversive pictures were rated as less unpleasant compared with the other conditions. Additionally, arousal levels were rated lower immediately following the articulating and voicing conditions in response to the positive pictures.

CONCLUSIONS

The findings showed that the act of making speech sounds, not simply voicing by itself, may influence the way we process emotions.

Taking the mystery away from shared intentionality: The straightforward view and its empirical implications

Ordinary language in Western and non-Western cultures individuates shared mental states or experiences as unitary interpersonal events that belong to more than one individual. However, a default assumption in modern Western thought is that, in this regard, ordinary language is either illusory or merely metaphorical: a mental state or experience can belong to only one person. This assumption is called Cartesian eliminativism and is often taken to be foundational in psychology. It follows that any view that contradicts Cartesian eliminativism is a priori suspected of being "mysterious," i.e., of not meeting scientific standards. This paper suggests that the very opposite may be the case. The straightforward view explains how individuals assemble and experience a shared mental state as a unitary whole whose components are distributed among the participants. The naturalistic advantages of such a view are brought to light by focusing on developmental science. Since it explains early shared emotions, goals, and attention merely by relying on domain-general, associative processes, the straightforward view is more parsimonious than current psychological theories. Indeed, it abandons the cumbersome postulates of (i) multi-level recursive mindreading and (ii) a special, conceptually elusive phenomenal quality. I outline the distinctive developmental predictions of the view and discuss how it accounts for the functions of shared mental states. As a reductionist, non-eliminativist approach, the straightforward view promises to be viable also for cognitive scientists who have so far worked within the Cartesian framework due to a lack of a rigorous and sufficiently developed alternative.

A New Perspective on Assessing Cognition in Children through Estimating Shared Intentionality

This theoretical article aims to create a conceptual framework for future research on digital methods for assessing cognition in children through estimating shared intentionality, different from assessing through behavioral markers. It shows the new assessing paradigm based directly on the evaluation of parent-child interaction exchanges (protoconversation), allowing early monitoring of children’s developmental trajectories. This literature analysis attempts to understand how cognition is related to emotions in interpersonal dynamics and whether assessing these dynamics shows cognitive abilities in children. The first part discusses infants’ unexpected achievements, observing the literature about children’s development. The analysis supposes that due to the caregiver’s help under emotional arousal, newborns’ intentionality could appear even before it is possible for children’s intention to occur. The emotional bond evokes intentionality in neonates. Therefore, they can manifest unexpected achievements while performing them with caregivers. This outcome shows an appearance of protoconversation in adult-children dyads through shared intentionality. The article presents experimental data of other studies that extend our knowledge about human cognition by showing an increase of coordinated neuronal activities and the acquisition of new knowledge by subjects in the absence of sensory cues. This highlights the contribution of interpersonal interaction to gain cognition, discussed already by Vygotsky. The current theoretical study hypothesizes that if shared intentionality promotes cognition from the onset, this interaction modality can also facilitate cognition in older children. Therefore in the second step, the current article analyzes empirical data of recent studies that reported meaningful interaction in mother-infant dyads without sensory cues. It discusses whether an unbiased digital assessment of the interaction ability of children is possible before the age when the typical developmental trajectory implies verbal communication. The article develops knowledge for a digital assessment that can measure the extent of children’s ability to acquire knowledge through protoconversation. This specific assessment can signalize the lack of communication ability in children even when the typical trajectory of peers’ development does not imply verbal communication.

Does Neonatal Imitation Exist? Insights From a Meta-Analysis of 336 Effect Sizes

Neonatal imitation is a cornerstone in many theoretical accounts of human development and social behavior, yet its existence has been debated for the past 40 years. To examine possible explanations for the inconsistent findings in this body of research, we conducted a multilevel meta-analysis synthesizing 336 effect sizes from 33 independent samples of human newborns, reported in 26 articles. The meta-analysis found significant evidence for neonatal imitation (d = 0.68, 95% CI = [0.39, 0.96], p < .001) but substantial heterogeneity between study estimates. This heterogeneity was not explained by any of 13 methodological moderators identified by previous reviews, but it was associated with researcher affiliation, test of moderators (QM) (15) = 57.09, p < .001. There are at least two possible explanations for these results: (a) Neonatal imitation exists and its detection varies as a function of uncaptured methodological factors common to a limited set of studies, and (2) neonatal imitation does not exist and the overall positive result is an artifact of high researcher degrees of freedom.

The interplay between early social interaction, language and executive function development in deaf and hearing infants

In this article, we review the influence of early social interaction on the development of executive function and language in infants. We first define social interaction, executive function and language and show how they are related in infant development. Studies of children born deaf are used to illustrate this connection because they represent cases where there has been a disruption to early social interaction and the development of intersubjectivity. Unlike other groups, the disturbance to development is known to be largely environmental rather than neuro-biological. This enables us to more accurately tease apart those impacts on EF that are associated with social interaction and language, since the potential confounds of disordered cognitive development are largely controlled for. The review offers a unifying model for how social, cognitive and linguistic development work together in early human development.

Pregnant Agencies: Movement and Participation in Maternal-Fetal Interactions

Pregnancy presents some interesting challenges for the philosophy of embodied cognition. Mother and fetus are generally considered to be passive during pregnancy, both individually and in their relation. In this paper, we use the enactive operational concepts of autonomy, agency, individuation, and participation to examine the relation between mother and fetus in utero. Based on biological, physiological, and phenomenological research, we explore the emergence of agentive capacities in embryo and fetus, as well as how maternal agency changes as pregnancy advances. We show that qualitatively different kinds of agency have their beginnings already in utero, and to what extent fetal and maternal movement modulate affectivity and individuation in pregnancy. We thus propose that mother and fetus are both agents who participate in pregnancy. Pregnancy then emerges as a relational developmental organization that anchors and holds its developing participants. We end the paper with reflections on ethical implications of this proposal, and suggestions for future research.

The Comparative Psychology of Intelligence: Some Thirty Years Later

After re-reading Macphail's (1987) essay "The Comparative Psychology of Intelligence" with all the associated commentaries, I was struck by how contemporary many of the arguments and counter-arguments still appear. Of course, we now know much more about the abilities of many more species (including their neurobiology) and fewer researchers currently favor explanations of behavior based solely on associative processes; however, the role of contextual variables in comparative psychology still remains cloudy. I discuss these issues briefly. Given my research interests involving the cognitive and communicative abilities of Grey parrots, the one aspect of the original article upon which I feel I can comment in depth involves Macphail's claims about the importance of language-and specifically syntax-in problem-solving and thus in placing humans above all other creatures. Granted, no other species has (or in my opinion is likely ever to acquire) everything that goes into what is considered "human language." Nevertheless, several other species have acquired symbolic representation, and considerable information now exists upon which to base an argument that such acquisition by itself enables more complex and "human-like" cognitive processes. Such processes may form the basis of the kind of intelligence that is measured-not surprisingly-with human-based tasks, including the use of such representations as a means to directly query non-human subjects in ways not unlike those used with young children.

An unsettled debate: Key empirical and theoretical questions are still open

Debates about neonatal imitation remain more open than Keven & Akins (K&A) imply. K&A do not recognize the primacy of the question concerning differential imitation and the links between experimental designs and more or less plausible theoretical assumptions. Moreover, they do not acknowledge previous theorizing on spontaneous behavior, the explanatory power of entrainment, and subtle connections with social cognition.

Self-defense: Deflecting Deflationary and Eliminativist Critiques of the Sense of Ownership

I defend a phenomenological account of the sense of ownership as part of a minimal sense of self from those critics who propose either a deflationary or eliminativist critique. Specifically, I block the deflationary critique by showing that in fact the phenomenological account is itself a deflationary account insofar as it takes the sense of ownership to be implicit or intrinsic to experience and bodily action. I address the eliminativist view by considering empirical evidence that supports the concept of pre-reflective self-awareness, which underpins the sense of ownership. Finally, I respond to claims that phenomenology does not offer a positive account of the sense of ownership by showing the role it plays in an enactivist (action-oriented) view of embodied cognition.
