Positive evidence for neonatal imitation: A general response,adaptive engagement

The study employed four gestural models using frame‐by‐frame microanalytic methods, and followed how the behaviours unfolded over time. Forty‐two human newborns (0–3 days) were examined for their imitation of tongue protrusion, ‘head tilt with looking up’, three‐finger and two‐finger gestures. The results showed that all three gesture groups were imitated. Results of the temporal analyses revealed an early and a later, second stage of responses. Later responses were characterized by a suppression of similar, but non‐matching movements. Perinatal imitation is not a phenomenon served by a single underlying mechanism; it has at least two different stages. An early phase is followed by voluntary matching behaviour by the neonatal infant.     

Using imitation with congenitally deafblind adults: establishing meaningful communication partnerships

All congenitally deafblind people are potential communication partners. The key question for practitioners is how to help them achieve that potential. Imitation offers a particularly powerful means of doing so because it allows both partners to occupy a joint dyadic space, where the process of repairing the damaged communication partnerships that many deafblind people have been forced to function within throughout their lives can begin. I will first outline a brief history of deafblind education over the last 150 years in order to provide a general account of changes in practice and theory and corresponding impacts on interventions. I will then describe some of the difficulties that congenitally deafblind people face in making contact with and being understood by other people before drawing on both practical examples and theoretical accounts on neonatal imitation to examine four key functions that imitation plays in facilitating communicative exchanges between deafblind individuals and their partners: it attracts attention, it stimulates turn‐taking, it allows partners to recognize each other and it reveals the other as ‘just like me’. I will conclude that imitation is simply the starting place for a journey towards a ‘natural’ language for congenitally deafblind people, a language where meanings are jointly negotiated from the actions, gestures and vocalizations that develop between deafblind people and their communication partners. This starting place is the same for congenitally deafblind people as it is for all infants: a companion space where imitation acts a powerful and immediate source of feedback about your value as a fellow human being.

从动作模仿到社会认知：自我-他人控制的作用

在社会互动中, 人们具有自动模仿他人动作的倾向。尽管这种自动模仿有利于个体理解他人动作的感受, 但有时也会与自身的动作意图产生冲突。因此我们需要将自身动作意图与他人动作进行区分并调控二者之间的冲突。这种能力被称为自我-他人控制(self-other control, SOC)。与动作模仿控制相同, 心理理论、观点采择和共情等更高级的社会认知同样涉及对自我和他人信息的加工。很多证据表明, SOC可能是一种领域普遍的(domain-general)加工机制, 即在动作模仿控制和其他社会认知中, 大脑对自我和他人双方信息的区分和冲突调控共用同一套SOC系统。最近一些研究发现, 相比于抑制自身优势反应的抑制控制(inhibitory control), SOC是社会认知中一个更为关键的影响因素, 抑制控制对社会认知的作用受到SOC的调节。此外, SOC的领域普遍性提示我们, 未来可以通过简单的动作模仿控制训练, 来为社会认知受损个体(如孤独症和述情障碍者)进行康复训练。     

Spontaneous imitation in the social interactions of young people with developmental delay and their adult carers

This paper examines the presence of spontaneous imitation within the social interactions of young people with developmental delay and their adult carers. There have been only a handful of observational studies examining imitation in this population, despite the relevance of such work to contemporary theoretical debates about imitation and the potential that imitation holds as an intervention for promoting communicative skills. The play of eight young people and 13 adult carers over 10 sessions at an after‐school club was videotaped and analysed for the presence and impact of spontaneous imitative bouts. Results showed that, in the majority of cases, it was adults who initiated imitative bouts and that the young people generally did not reciprocate such acts. However, even such brief instances of adult imitation were sufficient to increase the children's subsequent smiles and speech vocalizations, as well as the adults' own use of smiling, eye contact, and speech vocalizations. These findings confirm that these young people are sensitive to imitation. The implications for designing interventions that promote communicative exchanges in young people with developmental delay are discussed. Copyright © 2006 John Wiley & Sons, Ltd.

镜像神经元系统的发现使得研究者从一个较为统一的神经机制层面了解人类多个层次的社会认知活动。在猕猴大脑F5区发现的镜像神经元可以在抽象的层面上帮助猕猴理解他人行为的意图。利用脑成像技术,研究发现人类的镜像神经元系统能够匹配外界的知觉表征和内在的动作表征从而通过“居身模仿”这一过程来进行模仿、语言理解、理解他人的意图及情绪这些重要的社会认知活动。另外,镜像神经元系统在社会交往中也起着重要作用,最后,就镜像神经元系统在心理理论中的作用、了解自我-他人问题和镜像神经元系统的关系、动机、经验等因素对镜像神经元系统活动的调控等问题对未来的研究方向进行了展望     

From intersubjectivity to subjectivity: the transformative roles of emotional intimacy and imitation

How is the transition between intersubjectivity and subjectivity accomplished? While many developmental theorists have argued that social interaction gives rise to individualistic capacities (e.g. representation, language, consciousness), relatively few theorists have attempted to identify the precise mechanisms that might be responsible for this transformation. The present paper addresses this gap by drawing attention to the central role played by emotional intimacy. It is argued that subjectivity arises out of intimate engagement with others, and particular attention is given to the role of imitation in fostering such intimacy. While the primary focus is on infant development, links are made to work with atypical populations because they offer valuable insights into the developmental processes under consideration here. The ultimate aim of the paper is to demonstrate that by recognizing the emotional intimacy inherent within adult–infant interactions, new solutions are offered to theoretical problems that developmental psychology continues to face in accounting for the origins of subjectivity.

Generalization of deferred imitation during the first year of life

Infants first generalize across contexts and cues at 3 months of age in operant tasks but not until 12 months of age in imitation tasks. Three experiments using an imitation task examined whether infants younger than 12 months of age might generalize imitation if conditions were more like those in operant studies. Infants sat on a distinctive mat in a room in their home (the context) while an adult modeled actions on a hand puppet (the cue). When they were tested 24 h later, 6-month-olds generalized imitation when either the mat or the room (but not both) differed, whereas 9-month-olds generalized when both the mat and the room differed. In addition, 9-month-olds who imitated immediately also generalized to a novel test cue, whereas 6-month-olds did not. These results parallel results from operant studies and reveal that the similarity between the conditions of encoding and retrieval-not the type of task-determines whether infants generalize. The findings offer further evidence that memory development during infancy is a continuous function.     

Fronto-parietal mirror neuron system modeling: Visuospatial transformations support imitation learning independently of imitator perspective

Although the human mirror neuron system (MNS) is critical for action observation and imitation, most MNS investigations overlook the visuospatial transformation processes that allow individuals to interpret and imitate actions observed from differing perspectives. This problem is not trivial since accurately reaching for and grasping an object requires a visuospatial transformation mechanism capable of precisely remapping fine motor skills where the observer’s and imitator’s arms and hands may have quite different orientations and sizes. Accordingly, here we describe a novel neural model to investigate the dynamics between the fronto-parietal MNS and visuospatial processes during observation and imitation of a reaching and grasping action. Our model encompasses i) the inferior frontal gyrus (IFG) and inferior parietal lobule (IPL), regions that are postulated to produce neural drive and sensory predictions, respectively; ii) the middle temporal (MT) and middle superior temporal (MST) regions that are postulated to process visual motion of a particular action; and iii) the superior parietal lobule (SPL) and intra-parietal sulcus (IPS) that are hypothesized to encode the visuospatial transformations enabling action observation/imitation based on different visuospatial viewpoints. The results reveal that when a demonstrator executes an action, an imitator can reproduce it with similar kinematics, independently of differences in anthropometry, distance, and viewpoint. As with prior empirical findings, similar model synaptic activity was observed during both action observation and execution along with the existence of both view-independent and view-dependent neural populations in the frontal MNS. Importantly, this work generates testable behavioral and neurophysiological predictions. Namely, the model predicts that i) during observation/imitation the response time increases linearly as the rotation angle of the observed action increases but remain similar when performing both clockwise and counterclockwise rotation and ii) IPL embeds essentially view-independent neurons while SPL/IPS includes both view-independent and view-dependent neurons. Overall, this work suggests that MT/MST visuomotion processes combined with the SPL/IPS allow the MNS to observe and imitate actions independently of demonstrator-imitator spatial relationships.

Mother versus stranger: a triadic situation of imitation at the end of the first year of life

This study presents two experiments investigating 8‐ and 12‐month‐old infants' imitative behaviour. Seventy‐two 8‐month‐olds and seventy‐two 12‐month‐olds were observed in a triadic situation which included their mother and a stranger. Depending on the condition, either the mother or the stranger acted as the demonstrator and either stayed close or withdrew after the demonstration, during the response period. In addition to imitative acts, visual exploration and smiles addressed, respectively, to each partner were computed. Results showed that at both ages, neither the familiarity nor the position of the partner has an effect on the number of target gestures that are imitated. At 12 months, infants looked and smiled more at the stranger when he demonstrated target actions but no difference was found when the mother acted as demonstrator. Moreover, 12‐month‐old infants looked more at the demonstrating partner immediately after their first imitation. At 8 months, infants paid more attention to the stranger in all conditions except when the mother performed the target actions and moved away, a pattern that suggests a referencing to the mother. Results from the gaze and smile variables suggest that with age different motivations (social contact, exploration of objects) induce imitation. Copyright © 2003 John Wiley & Sons, Ltd.     

The history of imitation in learning theory: the language acquisition process

The concept of imitation has undergone different analyses in the hands of different learning theorists throughout the history of psychology. From Thorndike's connectionism to Pavlov's classical conditioning, Hull's monistic theory, Mowrer's two-factor theory, and Skinner's operant theory, there have been several divergent accounts of the conditions that produce imitation and the conditions under which imitation itself may facilitate language acquisition. In tracing the roots of the concept of imitation in the history of learning theory, the authors conclude that generalized imitation, as defined and analyzed by operant learning theorists, is a sufficiently robust formulation of learned imitation to facilitate a behavior-analytic account of first-language acquisition.     

Speaking the other's language: imitation as a gateway to relationship

Imitation offers a gateway to relationship. This paper seeks to explore that capacity by describing the therapeutic approach of ‘Intensive Interaction’. The research literature on imitation contains relatively little about imitation used in an intervention capacity, concentrating instead on the emergence of imitative abilities during infant and child development. The paper therefore describes the case of a young man with severe autism, for whom Intensive Interaction was successful in bringing him into interpersonal engagement with others. The author provides an account as to why imitation should be so effective in this regard. Overall, the paper aims to stimulate questions about how imitation can best be conceived and studied.

Behavioral treatment of children with phonological disorder: the efficacy of vocal imitation and sufficient-response-exemplar training

This study examined whether sufficient-response-exemplar training of vocal imitation would result in improved articulation in children with phonological disorder, and whether improved articulation established in the context of vocal imitation would transfer to other verbal classes such as object naming and conversational speech. Participant 1 was 6 years old and attended first grade in a regular public school. Participant 2 was 5 years 4 months old and attended a public kindergarten. Both participants had normal hearing and no additional handicaps. A multiple baseline design across behaviors (target sounds or blends) was employed to examine whether the vocal imitation training resulted in improved articulation. Results showed that both participants improved articulation once training was implemented, and that the improved articulation transferred from vocal imitation to more natural speech such as object naming and conversational speech. Improvement established during training was maintained posttraining and at a 6-month follow-up.
