“Being‐Imitated” Strategy at Home‐Based Intervention for Young Children with Autism

Previous studies have consistently shown that simply imitating children with autism will help to promote amount of gaze and to decrease distance to others. However, whether the “being‐imitated” strategy also affects the development of social cognition has not been clarified. We conducted a 2‐month researcher‐guided and home‐based intervention. Mothers were randomly assigned to two groups: One group was coached to engage the child using imitation, and the other was coached simply to respond contingently to bids. Before and after the 2‐month intervention, imitation skills, understanding the intentions of others’ acts, and gaze toward mothers were measured. Two months of being‐imitated enables the children to raise the general amount of their gaze interaction. The imitation skills also were promoted. On the other hand, the development of understanding others’ intentions was not observed, irrespective of condition. The increase of attention to others, which is facilitated by the accumulation of the being‐imitated experiences, can be generalized to the nonimitating person and results in the imitation of others by the child. Alternatively, the developmental linkages between the being‐imitated strategy and understanding of others’ intentions should be an important research task. The present study also indicates that caretakers can play a significant role in the intervention for a child with autism.     

Preverbal children with autism understand the intentions of others

There is a ‘theory of mind’ theory of autism. Meltzoff has recently developed a procedure that gives a nonverbal assessment of ‘theory of mind’. A group of children with autism and a matched control group of normally developing infants were given three of Meltzoff’s tasks and three conventional, gestural imitation tasks. The children with autism showed the expected deficits on gestural imitation, but were significantly better than the normally developing infants on the Meltzoff tasks. The implications of these results for a number of theoretical issues are discussed.     

Examining the role of lexical frequency in the acquisition and processing of sentential complements

We present empirical data showing that the relative frequency with which a verb normally appears in a syntactic construction predicts young children's ability to remember and repeat sentences instantiating that construction. Children aged 2;10–5;8 years were asked to repeat grammatical and ungrammatical sentential complement sentences (e.g., ‘I think + S’). The sentences contained complement-taking verbs (CTVs) used with differing frequencies in children's natural speech. All children repeated sentences containing high frequency CTVs (e.g., think) more accurately than those containing low frequency CTVs (e.g., hear), and made more sophisticated corrections to ungrammatical sentences containing high frequency CTVs. The data suggest that, like adults, children are sensitive to lexico-constructional collocations. The implications for language acquisition are discussed.     

Musical metaphors: Evidence for a spatial grounding of non-literal sentences describing auditory events

This study investigated whether the spatial terms high and low, when used in sentence contexts implying a non-literal interpretation, trigger similar spatial associations as would have been expected from the literal meaning of the words. In three experiments, participants read sentences describing either a high or a low auditory event (e.g., The soprano sings a high aria vs. The pianist plays a low note). In all Experiments, participants were asked to judge (yes/no) whether the sentences were meaningful by means of up/down (Experiments 1 and 2) or left/right (Experiment 3) key press responses. Contrary to previous studies reporting that metaphorical language understanding differs from literal language understanding with regard to simulation effects, the results show compatibility effects between sentence implied pitch height and response location. The results are in line with grounded models of language comprehension proposing that sensory motor experiences are being elicited when processing literal as well as non-literal sentences.     

What preschool children do and do not do with ungrammatical word orders

Akhtar [J. Child Lang. 26 (1999) 339.] found that when 4-year-old English-speaking children hear novel verbs in transitive utterances with ungrammatical word orders (e.g., Elmo the tree meeked), they correct them to canonical SVO order almost all of the time. However, when 3-year-olds and older 2-year-olds hear these same utterances, they waver between correcting and using the ungrammatical ordering. In the current study, we adapted this task for children at 2;4, using an intransitive construction. The major finding was that children corrected the noncanonical word order less than half as often as Akhtar's 2-year-old subjects who were approximately 4 months older. At the same time, however, children showed in several ways that they had some implicit understanding of canonical SV order; for example, they used the novel verb which they heard used in grammatical word order more often than the novel verb which they heard in ungrammatical word order, and they consistently used pronouns and the progressive –s auxiliary in appropriate ways. The current findings thus contribute to a growing body of theory and research suggesting that the ontogenetic emergence of linguistic categories and schemas is a gradual process, as is the emergence of categories in other domains of cognitive development.     

Individual differences in neonatal “imitation” fail to predict early social cognitive behaviour

The influential hypothesis that humans imitate from birth – and that this capacity is foundational to social cognition – is currently being challenged from several angles. Most prominently, the largest and most comprehensive longitudinal study of neonatal imitation to date failed to find evidence that neonates copied any of nine actions at any of four time points (Oostenbroek et al., [2016] Current Biology, 26, 1334–1338). The authors of an alternative and statistically liberal post‐hoc analysis of these same data (Meltzoff et al., [2017] Developmental Science, 21, e12609), however, concluded that the infants actually did imitate one of the nine actions: tongue protrusion. In line with the original intentions of this longitudinal study, we here report on whether individual differences in neonatal “imitation” predict later‐developing social cognitive behaviours. We measured a variety of social cognitive behaviours in a subset of the original sample of infants (N = 71) during the first 18 months: object‐directed imitation, joint attention, synchronous imitation and mirror self‐recognition. Results show that, even using the liberal operationalization, individual scores for neonatal “imitation” of tongue protrusion failed to predict any of the later‐developing social cognitive behaviours. The average Spearman correlation was close to zero, mean r_s = 0.027, 95% CI [?0.020, 0.075], with all Bonferroni adjusted p values > .999. These results run counter to Meltzoff et al.'s rebuttal, and to the existence of a “like me” mechanism in neonates that is foundational to human social cognition.     

Preschoolers’ behavioural reenactment of “failed attempts”: The roles of intention-reading,emulation and mimicry

To clarify the nature of the social cognitive skills involved in preschoolers’ reenactment of actions on objects, we studied 31- and 41-month-old children's reenactment of intended acts (“failed attempts”) in Meltzoff's (Meltzoff, A. N. (1995). Understanding the intentions of others: Reenactment of intended acts by 18-month-old children. Developmental Psychology, 31, 838–850) behavioural reenactment paradigm. Measuring children's first action, performance of target acts was similar in a novel Emulation Learning condition to that seen in the Failed Attempt condition. In the Emulation Learning condition, children did not see the adult's manipulation and their response was likely to have been based on the end state specifying the object's key affordances. Both 31- and 41-month-old children also copied the control acts they had observed in the Adult Manipulation condition. However, 41-month-old but not 31-month-old children reproduced the failed attempt actions in the Failed Attempt condition. This pattern of findings suggests that, whilst 2- to 3-year-olds mimic adults’ actions when these actions do not trigger alternative object affordances, only in the third year of life will children mimic adults’ actions when these actions simultaneously trigger such affordances. Reenactment of actions on objects involves a number of social cognitive processes and exceptional care in the design of experiments is required to determine the roles played by intention-reading, emulation, and mimicry.     

Copying results and copying actions in the process of social learning: chimpanzees (Pan troglodytes) and human children (Homo sapiens)

There is currently much debate about the nature of social learning in chimpanzees. The main question is whether they can copy others' actions, as opposed to reproducing the environmental effects of these actions using their own preexisting behavioral strategies. In the current study, chimpanzees (Pan troglodytes) and human children (Homo sapiens) were shown different demonstrations of how to open a tube-in both cases by a conspecific. In different experimental conditions, demonstrations consisted of (1) action only (the actions necessary to open the tube without actually opening it); (2) end state only (the open tube, without showing any actions); (3) both of these components (in a full demonstration); or (4) neither of these components (in a baseline condition). In the first three conditions subjects saw one of two different ways that the tube could open (break in middle; caps off ends). Subjects' behavior in each condition was assessed for how often they opened the tube, how often they opened it in the same location as the demonstrator, and how often they copied the demonstrator's actions or style of opening the tube. Whereas chimpanzees reproduced mainly the environmental results of the demonstrations (emulation), human children often reproduced the demonstrator's actions (imitation). Because the procedure used was similar in many ways to the procedure that Meltzoff (Dev Psych 31:1, 1995) used to study the understanding of others' unfulfilled intentions, the implications of these findings with regard to chimpanzees' understanding of others' intentions are also discussed.     

Change in children's understanding of others' intentional actions

The study investigated children's intention understanding using a longitudinal design. Thirty-two Italian children were tested on the 'Demonstration of Intention' in the Re-enactment paradigm devised by Meltzoff (1995a), at two ages. Mean age was 12 months at the first session and 15 months at the second session. Previous research by Meltzoff showed that 18-month-olds are able to re-enact what the adult intended to do, when an adult tried but failed to perform certain target acts. Bellagamba and Tomasello (1999) found that, compared to 18-month-olds, 12-month-olds are less able to imitate unsuccessful goal-directed actions. The current study had two main goals. The first was to replicate earlier findings on intention understanding in 12- and 15-month-olds longitudinally assessed. The second goal was to analyse which actions children perform when not producing the target act. A coding scheme was devised to evaluate these non-target actions. Results confirmed previous findings, i.e. children's tendency to produce the target act was higher at an older age. At a younger age the most frequent response was 'undifferentiated manipulation' of target objects, followed by 'approximation to the target action'. Since children differed in their intention understanding performance at the first session, we decided to check whether these individual differences remained stable at the second session. Individual children with high intention understanding performance at 12 months tended to remain high at 15 months of age.     

婴儿如何认识他心：“似我”假说述评

Meltzoff的“似我”假说认为,婴儿借助“我他对等”认识解读他人行为和心理状态,通过他人间的互动信息推断和调整自身行为。“似我”认识以动作表征为基础,借助第一人称体验建立双向映射,对“似我”之人进行因果推理,由此构成发展路径引导婴儿认识他心。注视追随与模仿两种初级社会学习机制进一步丰富了婴儿对社交关系的理解,使人类学习的渠道突破了自我体验的局限而变得更加多元。     

Elicited imitation in lexical development: Evidence from a study of temporal reference

This study examined the use of elicited imitation in investigating lexical development within a semantic domain. For this purpose the acquisition of reference to sequence and simultaneity by 3–5 year old children was examined. Three factors were proposed to account for the order in which lexical items within a semantic field are acquired: restrictedness of a lexical item, congruence with perceptual strategies, and conceptual simplicity. A significantly greater number of correct responses was found in sentences describing sequential events than in simultaneous events. Furthermore, imitations of sentences referring to simultaneity were more degraded than imitations of sentences referring to sequence. The children seemed to begin acquiring reference to temporally related events by learning about words describing serially ordered events. A three stage developmental model is proposed to account for the results.Some of the data reported here are drawn from the author's doctoral dissertation from the Department of Linguistics, State University of New York, Buffalo, 1974.     

Are “late-signing” deaf children “mindblind”? Understanding goal directedness in imitation

Recent studies with “late-signing” deaf children (deaf children born into families in which no-one uses a sign language) have indicated that they have difficulty performing tasks that require them to reason about other people's false beliefs. However, virtually no research has so far investigated how far late signers’ difficulties with mental state understanding extend. This paper reports one study that uses an imitation paradigm to examine whether late signers may also have difficulty in interpreting other people's actions in terms of their goals. Both late-signing (N = 15) and second generation “native-signing” deaf children (N = 19) produced a pattern of responses to this task that indicates that they can and readily do view the actions of others as goal-directed. We conclude that this form of mental state understanding (generally seen as a precursor to understanding false beliefs) is intact in late-signing deaf children.     

Children's comprehension of comparative forms

Children aged from 3.5 to 5.5 years were tested on their comprehension of the terms taller, shorter, more, and less in five types of sentences: truncated, explicit standard, expanded explicit standard, two-dimensional second-clause subject noun, and two-dimensional second-clause subject pronoun. Many childen performed poorly on less and shorter in truncated sentences; the presence of explicit comparative cues did not improve these children's performance. Children who performed perfectly on truncated sentences still had difficulty understanding two-dimensional comparisons, especially those with a second-clause subject pronoun. These children interpreted only the first clause of the second-clause subject pronoun sentences. The results suggest that many children are capable of understanding two-dimensional comparisons, but perform poorly on the second-clause subject pronoun sentences because of uncertainty about the referent of the pronoun.     

The effect of amplitude modulation on intelligibility of time-varying sinusoidal speech in children and adults

Although researchers are currently studying auditory object formation in adults, little is known about the development of this phenomenon in children. Amplitude modulation has been suggested as one of the characteristics of the speech signal that allows auditory grouping. In this experiment, we evaluated children (4 to 13 years of age) and adults to examine whether children's ability to use amplitude modulation (AM) in perception of time-varying sinusoidal (TVS) sentences is different from that of adults, and whether there are developmental changes. We evaluated performance on recognition of TVS sentences (unmodulated, amplitude-comodulated at 25, 50, 100, and 200 Hz, and amplitude-modulated using conflicting frequencies). Overall, the youngest children performed more poorly than did older children and adults. However, difference scores, defined as the percentage of phonemes correct in a given modulation condition minus the percentage correct for the unmodulated condition, showed no significant effects of age. Unlike the findings of previous studies (Carrell & Opie, 1992), these results support the ability of modulation with conflicting frequencies to improve intelligibility. The present study provides evidence that children and adults receive the same benefits (or decrements) from amplitude modulation.     

Children's understanding of communicative intentions in the middle of the second year of life

Two tasks were administered to 40 children aged from 16 to 20 months (mean age = 18;1), to evaluate children's understanding of declarative and informative intention [Behne, T., Carpenter, M., & Tomasello, M. (2005). One-year-olds comprehend the communicative intentions behind gestures in a hiding game. Developmental Science, 8, 492–499; Camaioni, L., Perucchini, P., Bellagamba, F., & Colonnesi, C. (2004). The role of declarative pointing in developing a theory of mind. Infancy, 5, 291–308]. In the first task, children had to respond to the experimenter who pointed at a distal object; in the second task, children had to find a toy in a hiding game after the experimenter indicated the correct location either by pointing or by gazing. In the first task, most children responded to the declarative gesture by “commenting” on the pointed object instead of just looking; however, looking responses were more frequent than commenting responses. In the second task, children chose the correct location of the object significantly more frequently when the informative gesture was the point than when it was the gaze; moreover, there were significantly more correct choices than incorrect choices in the point but not in the gaze condition. Finally, no significant relation was found between tasks. Taken together, the findings support the view that infants’ developing understanding of communicative intention is a complex process in which general cognitive abilities and contextual factors are equally important.     

The effect of grammatical complexity upon disfluency behavior of nonstuttering preschool children

The effect of grammatical complexity on the disfluency behavior of nonstuttering 3- and 4-yr-old children was examined. Thirty normal children repeated after the examiner 30 sentences which represented six different grammatical constructions. These grammatical constructions represented a range of grammatical complexity.The total number of disfluencies that occurred in each sentence type was compared. The occurrence of specific disfluency categories in each sentence type was also examined. Subjects produced significantly more disfluencies on passive sentences than on any other sentence type. The passive elicited significantly more interjections, word repetitions, and revisions than the other sentence types.The effect of sentence type on imitation performance was also examined. The auxiliary Have and negative sentence types elicited significantly more imitation errors than other sentence types. Initiation and fluency performance for individual subjects were also examined.The results of the present investigation suggest that when grammatical complexity is controlled, the relationship between disfluencies and grammatical complexity is complicated. When grammatical constructions were relatively difficult for children, complexity affected the occurrence of disfluencies. However, factors other than grammatical complexity affect the occurrence of disfluencies in pre-school children.     

Semantic representations as procedures for verification

Doubly quantified sentences can be ambiguous (Every man knows some woman) or unambiguous (Every man knows every woman). For active and passive sentences of these types, we elicited from subjects three types of judgments designed to reflect which quantifier they assigned wide scope in interpreting the sentence. There was a strong tendency for the three measures to agree, and for these agreements to fall on the surface structure subject of the sentence, independent of sentence type. The data are interpreted as showing a tendency for the first quantifier to include the second within its scope; thus for both ambiguous and unambiguous sentence types active sentences tend to be interpreted differently from their passive transforms. A semantic theory adequate to capture this phenomenon must assign sentences semantic representations specifying not only truth-conditions but also procedures for verification.     

The Role of Personality, Psychopathy, and Previous Experience with Assessment in Intentions to Fake in Psychological Testing

Much research has addressed the possible antecedents of faking behaviour, however these approaches tend to be theoretical rather than empirical in nature. This study empirically examined for the first time the role of personality and previous experience with psychological testing in intentions to fake on psychological assessment. Participants (N?=?232 community members, n?=?175 females, n?=?58 males) completed the HEXACO-60 measure of personality, a measure of primary and secondary psychopathy, provided information on whether they had experience in psychological assessment, and rated their intentions to fake in future psychological testing. Analysis via hierarchical multiple regression indicated lower levels of conscientiousness, higher levels of psychopathy, and previous experience with psychological testing significantly predicted intentions to engage in faking in future assessment. In addition, lower levels of secondary psychopathy were also associated with intentions, however inspection of zero-order correlations suggested this influence was via a suppressor effect. These results provide insight into the mechanisms predicting intentions to fake in psychological testing, which may subsequently inform recruiting or diagnostic practices.     

Children infer affiliative and status relations from watching others imitate

We investigated whether young children are able to infer affiliative relations and relative status from observing others' imitative interactions. Children watched videos showing one individual imitating another and were asked about the relationship between those individuals. Experiment 1 showed that 5‐year‐olds assume that individuals imitate people they like. Experiment 2 showed that children of the same age assume that an individual who imitates is relatively lower in status. Thus, although there are many advantages to imitating others, there may also be reputational costs. Younger children, 4‐year‐olds, did not reliably make either inference. Taken together, these experiments demonstrate that imitation conveys valuable information about third party relationships and that, at least by the age of 5, children are able to use this information in order to infer who is allied with whom and who is dominant over whom. In doing so, they add a new dimension to our understanding of the role of imitation in human social life.
