The relationship between attention and deferred imitation in 12-month-old infants

Imitation is a frequent behavior in the first years of life, and serves both a social function (e.g., to interact with others) and a cognitive function (e.g., to learn a new skill). Infants differ in their temperament, and temperament might be related to the dominance of one function of imitation. In this study, we investigated whether temperament and deferred imitation are related in 12-month-old infants. Temperament was measured via the Infant Behavior Questionnaire Revised (IBQ-R) and parts of the Laboratory Temperament Assessment Battery (Lab-TAB). Deferred imitation was measured via the Frankfurt Imitation Test for 12-month-olds (FIT-12). Regression analyses revealed that the duration of orienting (IBQ-R) and the latency of the first look away in the Task Orientation task (Lab-TAB) predicted the infants’ imitation score. These results suggest that attention-related processes may play a major role when infants start to imitate.     

Memory by association: Integrating memories prolongs retention by two-year-olds

Recalling one memory often leads to the recollection of other memories that share overlapping features. This phenomenon, spreading activation, was originally documented in studies conducted with verbal adults, and more recently, it has been demonstrated with preverbal infants. Here, we examine the effect of spreading activation on long-term retention by 2-year-olds. Participants were tested in the Visual Recognition Memory (VRM) paradigm and the deferred imitation paradigm. Typically, infants of this age exhibit retention in the VRM paradigm for 24 h, while they exhibit retention in the deferred imitation paradigm for at least 8 weeks. In the present experiment, we paired these tasks together during original encoding and tested infants after an 8-week delay. Two-year-olds exhibited retention in both tasks. That is, when these two tasks initially occurred together – one task that is extremely memorable and one that is not – retrieving the memory of the more memorable task cued retrieval of the less memorable task, extending its longevity.     

唱音障碍的认知神经机制

唱音障碍是“五音不全”的一种表现形式。对唱音障碍的判定依赖于具体的评估方式、测试任务及测量指标。目前来看, 采用多任务、多指标以及相对标准是较为合理的办法。发生于歌唱过程(知觉、感觉运动转换、发声运动控制、记忆)中任一加工阶段的功能缺陷都可能导致唱音障碍, 但感觉运动转换缺陷被认为是唱音障碍的主要成因。最新的MMIA模型在内部模型的基础上描述了感觉运动转换缺陷的具体机制。未来研究一方面应进一步检验并完善当前的MMIA模型, 厘清唱音障碍的认知神经机制, 另一方面应利用现有成果为个体改善和提高自身的音准提供实质性的帮助。     

Dynamics of psychoanalytic supervision: a heuristic model

This paper presents a heuristic model for the dynamics of psychoanalytic supervision. It is not a manual for how to perform supervision, but a model for how to identify and think about the complex elements and forces influencing the supervisory process. The point of departure is that psychoanalysis is a composite craft in which seemingly contrary elements like strict rules and creative intuitions have their place and interact. Several aspects of supervision are discussed: aims, learning processes, teaching methods, relationship, emotional atmosphere and evaluation. Competence is given a pivotal place in the model. The main feature of the model is that these aspects of supervision are all seen as suspended in a field of dynamic tensions between phenomena in real or apparent opposition. One example of this is the tension in the supervisory relationship between supervisor as instructor acting as an authority for the candidate whilst being a mentor fostering autonomy in the candidate. It is argued that related kinds of dynamics characterize several aspects of psychoanalytic supervision and that these tensions are inherent in analytic work. In conclusion a key word picture of the model is presented.     

Sensory empathy and enactment1

The authors propose the concept of sensory empathy which emerges through contact between analyst and patient as they get in touch with an area concerning the primary bond. This area is not so much based on thoughts and fantasies as it is on physical sensations. Sensory empathy has to do with that instrument described by Freud as pertaining to the unconscious of any human, which enables one person to interpret unconscious communications of another person. The authors link this concept to that of enactment precisely because the latter concerns unconscious, early elements that fi nd in the act a fi rst meaningful expression. It involves both analyst and patient. In other words, the authors wish to emphasize the importance of the analytical process maintaining contact with that immense fi eld of human interaction that can be defi ned as primary sensory area and which becomes intertwined with the evolution of affects. Clinical examples are provided to clarify these hypotheses.

Mechanisms of change: exploring not only when and what,but also how declarative memory develops

Age‐related changes in representational flexibility are a characteristic feature of declarative memory development. The authors suggest that a qualitative shift in the nature of infants' memory representations accounts for increasing memory flexibility with age. We will argue that a comprehensive theory of declarative memory development must (1) account for the effect of experience on flexibility, (2) be empirically separable from more parsimonious explanations, and (3) propose a mechanism by which the transition takes place. We will argue that a converging‐methods approach is necessary to understand not only when and what develops in declarative memory, but also how developmental change occurs.

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.     

Reaction time indices of automatic imitation measure imitative response tendencies

In his review, Ramsey (2018) argues that it is currently unclear what reaction time indices of automatic imitation measure due to lacking research on their validity and domain-specificity. In our commentary, we argue that this conclusion is based on two misconceptions, namely that automatic imitation was designed as a laboratory measure of motor mimicry and that psychometric approaches to validity can readily be applied to experimental settings. We then show that reaction time indices of automatic imitation measure covert imitative response tendencies. Furthermore, while irrelevant for their validity, we argue that these indices are associated with some, but not necessarily all, types of overt imitation. Finally, we argue that mapping out the brain networks does not suffice to understand the brain processes underlying imitative control.
