Toward a reconceptualization of the reciprocal imitation phenomenon: Two experiments

This paper reports two experiments which consider the increased imitation exhibited by models who have been imitated. Experiment 1 was concerned with whether the reciprocal imitation effect is really reciprocal or if the subsequent imitation will generalize to someone else. It was found that adult subjects who were previously imitated at the 75% rate on a perceptual judgments task subsequently imitated their partner more, rated their partner more attractive, and felt more confidence when imitated than did subjects imitated at the 25% rate. These results were obtained regardless of which confederate the subjects imitated, thus indicating that reciprocal imitation is not necessarily reciprocal, but is generalizable. Experiment 2 assessed whether the subsequent imitation is the product of the effects of being imitated or is the result of the subject observing the imitator's imitation. The results indicated that after having observed imitation at a 75% rate, adult onlookers are more likely to subsequently imitate and be attracted to the imitator, the imitated person, and a person new to the situation than are onlookers who observed a 25% imitation rate. A theoretical modification is advanced which holds that subsequent imitation effects, whether from observing others imitate or from being the target of the imitation, result from a process of imitation of imitativeness. The results of these two experiments have implications for theory in imitation and social learning.     

Effects of relative nurturance and social power on observational learning and imitation

Preschool children observed two models, one of whom (controller of resources) controlled rewards dispensed to the child and to the other model (rival consumer of resources). The nurturance of the controller was varied in terms of his relative generosity towards the subject and rival consumer. Controllers were imitated to a greater extent than consumers only when the controller had been more nurturant to the child than to the rival consumer. Imitation of the controller and consumer were affected differently by the various conditions of nurturance, but children's learning of each model's behaviors were affected similarly by the conditions. The learning and imitative performance of each model's behaviors were uncorrelated, and imitation of one model did not correlate with imitation of the other. However, the learning of the two models' behaviors was highly correlated.     

Reciprocal Imitation Following Adult Imitation by Children with Autism

This study examined the effects of adult imitation and adult playfulness on the imitation, social attention and initiation of new behaviours by non‐verbal preschoolers with autism. Videotapes taken from a previous study were recoded for the adult's imitation and playful behaviour and the children's imitation, social attention (looking at the adult's actions) and initiation of new behaviours. In the original study, twenty non‐verbal, 4‐ to 6‐year‐old children with autism were randomly assigned to an imitation or a contingent responsivity group. Both groups of children engaged in an intervention phase (during which the adult imitated the children or contingently responded to them) and a subsequent spontaneous play phase (during which the adult interacted spontaneously with the children). ANOVA for the current study revealed that the imitation group children versus the contingent responsivity group children spent a greater percent time showing social attention and initiating new behaviours during the intervention phase and showing social attention and imitating the adult's behaviours during the subsequent spontaneous play phase. A correlation analysis yielded significant correlations between the percent time the adult imitated the child during the intervention phase and the percent time the child showed social attention during the same intervention phase and imitating the adult during the subsequent spontaneous play phase. Adult imitation and playfulness during the spontaneous play phase were also correlated with the children's social attention during that phase. Copyright © 2013 John Wiley & Sons, Ltd.     

“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.     

Imitation of Self-Stimulation:

Three autistic children participated in single subject, reversal designs to compare the impact of over correction and adult imitation on self-stimulation. In addition to continuous 10-second observations of frequency of self-stimulation during 10 minute sessions, experimenter and observer also rated the child's mood, attention to the experimenter and quality of attention paid. The order of interventions was randomized fro each subject with baseline preceding each intervention. Although each child's response pattern was unique, the data showed systematic changes in rates of self-stimulation across conditions for two of the children with mean levels of self-stimulation declining during the over correction procedure and increasing during imitation. There were parallel changes in mood and attention with all three children appearing “happiest” and most attentive when their self-stimulatory behavior was imitated by the adult. These results raise interesting possibilities for using adult imitation as a vehicle for establishing a reinforcing relationship with the autistic child.     

Behavioral similarity as a reinforcer for preschool children

Three experiments evaluated whether behavioral similarity provided by an adult could serve as a reinforcer for the modelling behavior of four preschoolers. In each experiment, sessions consisted of two kinds of trials: (1) experimenter-modelled trials, when the child's imitation of modelled motor responses was reinforced with praise and tokens, and (2) child-modelled trials when experimenter imitation of child-modelled responses was contingent upon the child's modelling one of three alternative responses: operation of a ball, horn, or clicker. Experiment I showed that the children consistently modelled whichever responses the experimenter imitated. Experiment II determined whether that performance was due to differences in the amount of experimenter behavior following imitated versus nonimitated child models or to experimenter imitation. Neither reducing nor increasing the amount of experimenter behavior following the children's nonimitated models altered their modelling of imitated responses. Experiment III evaluated whether experimenter imitation of child models was a reinforcer because the child's imitative responses were reinforced on experimenter-modelled trials. In Experiment III, the children's nonimitation of experimenter-models was reinforced with praise and tokens on a schedule of differential reinforcement of other behavior, yet they continued to model experimenter-imitated responses on child-modelled trials. These results indicate behavioral similarity was reinforcing, though no conditioning history through which it acquired that function was demonstrated.     

Imitation in language development: If,when, and why

In order to explore the function of imitation for first language learning, imitative and spontaneous utterances were compared in the naturalistic speech of six children in the course of their development from single-word utterances (when mean length of utterance was essentially 1.0) to the emergence of grammar (when mean length of utterance approached 2.0). The relative extent of imitation, and lexical and grammatical variation in imitative and spontaneous speech were determined. There were inter-subject differences in the extent of imitation, but each child was consistent in the tendency to imitate or not to imitate across time. For those children who imitated, there were both lexical and grammatical differences in imitative and spontaneous speech, and a developmental shift from imitative to spontaneous use of particular words and semantic-syntactic relations between words. The results are discussed as evidence of an active processing of model utterances relative to the contexts in which they occur for information for language learning.     

On being imitated: Effects on reward and reward value of the imitator

The effects of being imitated on the model's reward of imitating and nonimitating confederates and on the confederates' reward value were assessed. Forty-eight first graders served as subjects. It was found that more children showed a bias in giving reward to the imitating confederate than to the nonimitating confederate. This effect was particularly strong for children classified as having an internal locus of control. Second, no difference in confederates' reward value was obtained as measured by operantly conditioned responding on a marble-drop task.     

Response uncertainty and imitation: The interactive effects of age and task options

It was reasoned that younger children would be more susceptible to situational uncertainty and thereby imitate more than older children or peers of the same age tested under more structured conditions. Children 6- through 8- and 12- through 14-years-old observed a model toss a bean bag at a target and were tested for target relevant and incidental imitation under conditions of two task options (high structure) or 10 task options (low structure). On both measures of imitation, preadolescents in the low structure condition imitated significantly more than adolescents. Preadolescents also imitated more incidental behavior in the low than in the high structure condition. Additionally, it was found that personality variables predicted imitative behavior of younger subjects in the low structure condition only.     

Fourteen‐Month‐Olds' Imitation of Differently Aged Models

Studies comparing adult and peer imitation are rare and have to date provided mixed results. The aim of the present study was to investigate 14‐month‐olds' imitation of different actions (novel versus familiar) performed by televised models of different age groups (peers, older children or adults). In two experiments, we investigated infants' imitative performance when observing a novel action (Experiment 1) and familiar actions (Experiment 2). The results showed that the likelihood of imitating a novel action increased as the age of the model increased. The opposite was true for familiar actions where infants imitated the peer more frequently than either the older child or the adult model. These findings are discussed in relation to infants' ability to take into account a model's characteristics such as age when imitating actions. Copyright © 2011 John Wiley & Sons, Ltd.     

Reactions of third-graders to recognition allocation after being peer-imitated

Being imitated has generally been regarded as a positive experience conducive to reciprocal imitation of and increased attraction to one’s imitator. An experiment on 3rd-graders, in an adaptation of a Thelen-Kirkland paradigm, investigates whether the receipt of public recognition for a good product would simply amplify those positive effects, or would tend to reverse them, and explores whether gender would moderate models, reactions under such conditions. Recognition allocation was manipulated by having an “authority” award a symbolic star solely to the model, to the confederate imitator alone, to the confederate nonimitator alone, or to no one. The results suggested that the boys rather than girls showed amplification effects of receiving sole recognition: they reciprocally imitated more, and expressed greater attraction to, their same-sex imitator than did the girls. Overall, models expressed relatively less attraction to the imitator than to the nonimitator. When interviewed, the models were equally divided as to which of the two deserved the recognition when they themselves or their imitator received it, but they stated unequivocally that the nonimitator who received the recognition deserved it. They also clearly stated a preference for those tasks on which they themselves had been imitated—given that they themselves or their imitator had received recognition credit, compared to models in the nonimitator-recognition and control conditions. It is clear that recognition allocation is an important construct that should be considered in investigating models, reactions to being imitated, particularly in the light of its significance in the adult world, at least of this culture. Several directions are proposed for pursuing this construct further.

Children over-imitate adults and peers more than puppets

Researchers commonly use puppets in development science. Amongst other things, puppets are employed to reduce social hierarchies between child participants and adult experimenters akin to peer interactions. However, it remains controversial whether children treat puppets like real-world social partners in these settings. This study investigated children's imitation of causally irrelevant actions (i.e., over-imitation) performed by puppet, adult, or child models. Seventy-two German children (Age_Range = 4.6–6.5 years; 36 girls) from urban, socioeconomically diverse backgrounds observed a model retrieving stickers from reward containers. The model performed causally irrelevant actions either in contact with the reward container or not. Children were more likely to over-imitate adults’ and peers’ actions as compared to puppets’ actions. Across models, they copied contact actions more than no-contact actions. While children imitate causally irrelevant actions from puppet models to some extent, their social learning from puppets does not necessarily match their social learning from real-world social agents, such as children or adults.

Research Highlights

• We examined children's over-imitation from adult, child, and puppet models to validate puppetry as an approach to simulate non-hierarchical interactions.
• Children imitated adults and child models at slightly higher rates than puppets.
• This effect was present regardless of whether the irrelevant actions involved physical contact to the reward container or not.
• In our study children's social learning from puppets does not match their social learning from human models.

     

Facilitating accuracy of imitative articulation through reception training

Accuracy of imitation of nonsense words was examined in first- and second-grade children (65–99 months of age) as a function of prior reception training. Two experiments were conducted, involving within-subject comparisons. In the first, one group of words was trained as labels for nonsense objects, a second received noncontingent feedback yoked to the labeling words, a third was presented an equal number of times to control for exposure, and a fourth group was not included in the training phase. Testing involved accuracy of imitation of all four groups of words. Both the feedback and exposure words were imitated less accurately than the labeling words, but more accurately than the nonexposure controls. The second experiment examined the length of the label-object association, using an overtraining procedure. Words which came under the discriminative control of objects for greater numbers of trials were imitated more accurately than those meeting only a minimum discrimination criterion.     

Over‐imitation in children with autism and Down syndrome

Typically developing children have been shown to imitate the specific means used by an adult to achieve an object‐directed outcome, even if a more efficient method is available. It has been argued that this behaviour can be attributed to social and communicative motivations. The purpose of this study was to investigate whether children with autism spectrum disorders (ASD), relative to children with Down syndrome (DS), show a reduced tendency to copy the exact means used by an adult to produce a novel outcome. To achieve this a sample of 34 children (22 with ASD and 12 with DS) were given a test of object‐directed imitation. Contrary to expectation, children in both groups imitated the specific method of the model to the same high extent. This finding is in line with suggestions that object‐directed imitation is relatively spared in children with autism but is surprising given arguments linking such imitation to socially based motivations. Nevertheless, children's ability to successfully copy the model was associated with their communicative ability, providing some support for the link between imitation and communication.     

Imitation and locus of control

This study dealt with the relationship between Locus of Control and imitation. Based on a review of the social influence literature, it was hypothesized that external individuals would imitate equally under a condition of model-reward and a condition of no model-reward. It was further hypothesized that internal subjects would demonstrate more imitation under a condition of model-reward than under the condition of no model-reward. Male college students were classified as internal or external on the basis of their scores on the Locus of Control Scale. Internals imitated a rewarded model significantly more than a nonrewarded model. Externals imitated both models equally and at a rate comparable to internals who observed a rewarded model. Subject ratings of model competence were also positively related to imitation among internals but not among externals. The results are interpreted as offering support for the general notion of the effect of observer characteristics on imitation.     

The value of being imitated

Theories and research on the topics of attraction, conformity, and imitation support the view that the relational stimulus arising from being imitated serves a reinforcing function. To examine this possibility, 48 preschool children performed a task in which some neutral stimuli were repeatedly associated with an adult's matching the behavior of the subject, and other neutral stimuli were associated with the same adult's mismatching the behavior of the subject. Preference for the stimuli associated with being matched was greater at the end of training than earlier, and the overall preference for the matched stimuli exceeded chance. The results are considered in terms of the thesis that similarity arising from being imitated served a reinforcing function and the thesis that response strategies were adopted by the children.     

Imitation in toddlers as a function of motor and verbal aspects of modeling

This study investigated the effects of the motor and verbal aspects of modeling on imitation. The subjects were 2- and 3-year-old children (N = 96). The child's imitation responses were recorded during the play period that followed each modeled act. Each child observed the model in one of four modeling conditions. In Condition 1, the model "flew" a telephone while saying that he or she was flying an airplane. Imitation was recorded as motor if the child flew the telephone but was recorded as verbal and realistic if the child flew an airplane. In Condition 2, the model flew an airplane while saying that he or she was flying a telephone. Imitation was recorded as verbal if the child flew the telephone. In Condition 3, the model flew an airplane and said that he or she was flying an airplane. If the child flew an airplane, imitation was scored as motor, verbal, and realistic. In Condition 4, the model flew a telephone and said that he or she was flying a telephone. Imitation was scored as motor and verbal if the child flew the telephone but was scored as realistic if the child flew the airplane. In Condition 1, 2-year-olds displayed more motor imitation than 3-year-olds, and 3-year-olds displayed more verbal-reality imitation than 2-year-olds. Boys displayed more motor imitation than girls. There were no age or sex differences in Condition 2. In Condition 3, 2-year-olds imitated more than 3-year-olds, with 3-year-old girls imitating the least. In Condition 4, reality imitation was largely due to 2-year-old boys' imitation of masculine-type acts.     

Prior experiences and perceived efficacy influence 3-year-olds' imitation

Children are selective and flexible imitators. They combine their own prior experiences and the perceived causal efficacy of the model to determine whether and what to imitate. In Experiment 1, children were randomly assigned to have either a difficult or an easy experience achieving a goal. They then saw an adult use novel means to achieve the goal. Children with a difficult prior experience were more likely to imitate the adult's precise means. Experiment 2 showed further selectivity--children preferentially imitated causally efficacious versus nonefficacious acts. In Experiment 3, even after an easy prior experience led children to think their own means would be effective, they still encoded the novel means performed by the model. When a subsequent manipulation rendered the children's means ineffective, children recalled and imitated the model's means. The research shows that children integrate information from their own prior interventions and their observations of others to guide their imitation.     

The social control of generalized imitation

Instructions, discrimination procedures, and sources of reinforcement were manipulated in order to determine the bases for the maintained "non-reinforced" imitations observed in generalized imitation research. Six girls received imitation training from two experimenters. One experimenter modelled only reinforced responses; the other modelled only non-reinforced responses. The children imitated all responses when no reinforced alternative was available, even though results of choice procedures and special instructions clearly demonstrated that they discriminated reinforced from non-reinforced responses. Instructions not to perform non-reinforced imitations immediately eliminated these behaviors. It is suggested that social setting events may be largely responsible for generalized imitation.
