Patterns of imitation in mentally retarded children

Abstract.— In this report, the interchange theory of imitation was extended to mentally retarded children. Retardates were expected to observe and copy adults, using external cues and internal controls as aids. In Experiment I external cues were studied. Twenty-four speaking and 24 non-speaking retardates were paired with adults who gave half the children instructions to copy and the other half additional verbal and gestural cues. Non-speaking retardates receiving frequent cues attended and copied better than those getting initial instructions, gestural cues being equally or more effective than verbal ones. Speaking retardates getting repeated cues finished copying sooner than those getting only instructions, verbal and gestural cues being equally effective. In Experiment II internal controls over appropriate imitation were studied. Twenty-two retardates were trained to sit, observe and copy their teachers in a two-month program. Training was evaluated in situations where copying or playing was signalled. Overall, children attended and copied more in the appropriate situation. However, sitting, attention, and copying increased non-specifically in both situations, and initial situational differences in copying were not observed after treatment. The interchange theory was revised, and implications for attention-deficit and verbal self-control theories were discussed. Notions of "generalized imitation" were criticized.     

The effect of incongruent instructions and consequences on imitation in retarded children

Three retarded boys served as subjects in a 13-phase experiment. In eight of these phases, the instructions administered by the experimenter before demonstrating a behavior and the consequences for imitative behavior were incongruent (the consequences were not those indicated by the instructions). Consequences rather than instructions controlled imitative behavior when (a) subjects were instructed not to imitate but received reinforcers if they imitated; (b) subjects were instructed to imitate but were differentially reinforced for other behavior; (c) subjects were instructed to imitate but were verbally reprimanded for imitation. Although subjects were highly imitative at the beginning of the study, when there was no reinforcement for imitation subjects gradually stopped imitating when instructed not to imitate. Instructions seemed to control imitative behavior when there was no reinforcement for imitation and subjects were instructed to imitate. These results indicated a need for further investigation of antecedent and consequent variables in imitation experiments and pointed out that certain techniques may be more efficient than others in eliminating well-established responses.     

Preschool children favor copying a successful individual over an unsuccessful group

The human aptitude for imitation and social learning underpins our advanced cultural practices. While social learning is a valuable evolutionary survival strategy, blind copying does not necessarily facilitate survival. Copying from the majority allows individuals to make rapid judgments on the value of a trait, based on its frequency. This is known as the majority bias: an individual's tendency to copy the behavior elicited by the largest number of individuals in a population. An alternative approach is to follow those who are the most proficient. While there is evidence that children do show both processes, no study has directly pitted them against each other. To do this, in the current experiment 36 children aged between 4 and 5 years watched live actors demonstrate, as a group or individually, how to open novel puzzle boxes. Children exhibited a bias to the majority when group and individual methods were successful, but favored the individual if the group method was unsuccessful. Affiliating children with the unsuccessful majority group did not impact on this pattern.     

Same-sex imitation of and reported agreement with parents and unfamiliar adults

Children aged 7, 10, and 14 were shown sets of photographs of human figures for each of which they made judgments of age or attractiveness. Randomly determined responses appeared under each set of photographs. Half the children were told the responses represented choices of parents and the other half that they represented choices of unfamiliar adults. After the opportunity to imitate, children were asked whom they thought they agreed with the most. Findings indicated only a small, borderline-significant effect for same-sex imitation, but a large, highly significant effect for reported agreement, particularly in the unfamiliar adult condition (p < .001). Discussion centered on two issues: (1) Same-sex effects appear strongest when the act of choosing between adults and the adults' gender are accentuated; and (2) differences between present and previous findings regarding same-sex effects for parents vs unfamiliar adults may relate to the ages of the children investigated.     

The role of comprehension in children's observational learning of a syntactic rule

This experiment tested the hypothesis that there is a relationship between children's comprehension of a syntactic form and the effectiveness of modeling in promoting imitation of that form. Nursery and kindergarten children received pretests for both comprehension and production of reversible passive sentences. Children who produced no passive sentences were classified either as high, intermediate, or low comprehenders on the basis of their comprehension test performance. Within each of these three groups, children were randomly assigned either to a modeling or to a no-modeling control condition. Children in the treatment condition heard a model use passive sentences to describe a series of pictures. As predicted, the imitation post-test scores of these children were significantly related to their comprehension pretest scores. No significant relationship between the post-test scores and the comprehension scores of control subjects was detected. Children exposed to the model in all three comprehension groups received significantly higher post-test scores than did their respective counterparts in the no-modeling condition. These results are discussed in terms of the hypothesis that language learning proceeds from comprehension to imitation to production.     

Preschoolers' understanding of stable and changeable characteristics

Most adults can easily distinguish between stable characteristics, which affect personal identity, and changeable ones, which are free to vary within an individual. The purpose of this study was to investigate preschoolers' developing knowledge of stable (identity, gender, and race), changeable (mood, weight, and health), and changeable-but-irreversible (age and height) characteristics using pictorial and question tasks. In the first two experiments, 3-, 4-, and 5-year-old children and adults were asked to judge whether two pictures could represent the same person. Children in these experiments understood stable properties more clearly than changeable or irreversible ones. Children who made mistakes tended to treat changes in variable characteristics as if they altered personal identity. In Experiment 3, subjects answered questions about the stability or variability of the same characteristics. Children tested with questions in Experiment 3 showed a better understanding of stable and variable characteristics than did children tested with pictures in Experiments 1 and 2. Most of the children who erred in Experiment 3 understood stable attributes but treated changeable ones as if they were constant; however, a minority of children understood changeable properties but treated stable ones as if they were variable. These findings provide new information about how children understand and misunderstand the status of personal attributes.     

Effects of directiveness of instructions and surveillance on the production and persistence of children's donations

All subjects earned tokens for correct size judgments and observed a model who had previously earned tokens at the same task donate some of her earnings. Children were subsequently given an opportunity to donate some of their tokens to children at another school. The opportunity to give occurred in presence (surveillance) or absence of the experimenter and after being presented with either directive (you must give) or permissive (you can give if you want to) instructions. Directive instructions and surveillance both produced greater initial giving for all children. In a second session with no modeling, no surveillance, and no further instructions, earlier directive instructions also produced greater persistence of giving for all children. Permissive instructions produced greater reductions in giving over time for boys than for girls. The present findings suggest that directive instructions produce greater initial giving and that donating persists better under these more explicit conditions.     

Motor imagery during action observation enhances imitation of everyday rhythmical actions in children with and without developmental coordination disorder

Children with developmental coordination disorder (DCD) exhibit deficits both in imitation and motor imagery (MI) compared to typically developing children. Combined action observation and motor imagery (AO + MI) instructions can however enhance automatic imitation in both groups. In the present study we investigated the effects of AO + MI instructions on intentional imitation in children both with (n = 13) and without DCD (n = 12). On each trial participants observed and/or imagined before executing a familiar rhythmical pantomime action. These target actions were either habitually fast (tooth brushing or window wiping) or habitually slow (paint brushing or face washing), in the vertical or horizontal plane. Within each habitual speed, the target action speed was subtly manipulated across trials (fast vs. slow). Instruction condition was manipulated across three blocks of 16 trials: (1) observe before imitating the target action; (2) observe then imagine the action before imitating; (3) observe while imagining the same action before imitating (AO + MI). Kinematic analyses revealed typically developing children imitated the observed cycle times significantly better than children with DCD. A main effect of instruction showed imitation improved for AO + MI compared to the other two instructions. Within-group analyses found a significant advantage in DCD for AO + MI compared to observe then imagine. In typically developing children, imitation was significantly enhanced for AO + MI compared to observe then imitate. Combined AO + MI instructions therefore represent a promising new approach to refining performance of everyday rhythmical actions in children both with and without DCD, with implications for movement therapy and sports training.     

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.     

Teacher and peer reactions to boys' and girls' play styles

Seventy children (35 boys and 35 girls) aged 24 to 30 months were observed in play groups consisting of 12–15 2- and 3-year-old children and two teachers. The social interaction was coded using an observation schedule which allowed for coding the children's behaviors and reactions to that behavior by others in the environment. The behavior scores were factor analyzed, using the complete sample of 180 children with six factors (play styles) resulting. Children who were high and low on each factor were examined to see if play style influenced the type of social reaction received. Children who preferred to work at tasks quietly received positive teacher feedback, but there was no change in peer interaction; children who engaged in active motor play received positive peer feedback, but negative teacher reactions. Children who were passive received less peer reaction and played alone significantly more than other children. Sex differences in reactions did not appear except when the child was engaged in male- and female-typical behaviors when examining scores on one factor only. When combinations of factors are examined (e.g., activity level and task performance), then different patterns of responses start to appear for boys and girls. The implications for differing patterns of social reactions to different play styles are discussed.Data analyses were supported by BRSG Grant RR07980 awarded by the Biomedical Research Support Grant Program, Division of Research Resources, National Institutes of Health.

From children's hands to adults' ears: gesture's role in the learning process

Children can express thoughts in gesture that they do not express in speech--they produce gesture-speech mismatches. Moreover, children who produce mismatches on a given task are particularly ready to learn that task. Gesture, then, is a tool that researchers can use to predict who will profit from instruction. But is gesture also useful to adults who must decide how to instruct a particular child? We asked 8 adults to instruct 38 third- and fourth-grade children individually in a math problem. We found that the adults offered more variable instruction to children who produced mismatches than to children who produced no mismatches--more different types of instructional strategies and more instructions that contained two different strategies, one in speech and the other in gesture. The children thus appeared to be shaping their own learning environments just by moving their hands. Gesture not only reflects a child's understanding but can play a role in eliciting input that could shape that understanding. As such, it may be part of the mechanism of cognitive change.     

Children's responses to entry failure: attention deployment patterns and self-regulation skills

In this study the authors investigated associations among children's observed responses to failure in an analogue entry situation, their attention deployment patterns, and skills and processes associated with self-regulation. Participants were 54 kindergarten and first-grade students who were either aggressive-rejected or low aggressive-popular based on peer nominations. Inhibitory control predicted the tendency to respond to entry failure by stopping and watching the group's activity. Baseline vagal tone and other-directed attention predicted children's tendency to change entry strategies after failure. Parent-rated attention skills moderated the relation between children's attention deployment patterns during the entry task and their responses to entry failure. Children who engaged in more other-directed attention were less likely to turn to solitary play after entry failure but only if they had high or moderate levels of attentional control. Other-directed attention was related to repeating previous entry bids without modification after entry failure but only when children had high levels of attention problems.     

"Just stop thinking about it": effects of emotional disengagement on children's memory for educational material

Children regulate negative emotions in a variety of ways. Emotion education programs typically discourage emotional disengagement and encourage emotional engagement or "working through" negative emotions. The authors examined the effects of emotional disengagement and engagement on children's memory for educational material. Children averaging 7 or 10 years of age (N=200) watched either a sad or an emotionally neutral film and were then instructed to emotionally disengage, instructed to engage in problem solving concerning their emotion, or received no emotion regulation instructions. All children then watched and were asked to recall the details of an emotionally neutral educational film. Children instructed to disengage remembered the educational film better than children instructed to work through their feelings or children who received no emotion regulation instructions. Although past research has indicated that specific forms of emotional disengagement can impair memory for emotionally relevant events, the current findings suggest that disengagement is a useful short-term strategy for regulating mild negative emotion in educational settings.     

Event frequency and children's suggestibility: a study of cued recall responses

Research examining the effect of repeated experience on children's suggestibility for particular kinds of information has produced differing results. In one study, responses to recognition questions revealed heightened suggestibility for variable details in children who repeatedly experienced an event compared to children who experienced an event once. In other studies, no such effect was found with cued recall. In this study, 4–5‐year old children engaged in one or four play sessions. Children were later given a biasing interview wherein half of the details were incorrectly represented. Children were then given a final memory test using free and cued recall prompts that was preceded by one of three instruction types: no special instructions, moderate instructions, or opposition instructions. Children in the repeated‐event condition were more suggestible than those in the single‐event condition, regardless of instructions. No significant differences in suggestibility were found across instructions conditions. Copyright © 2004 John Wiley & Sons, Ltd.     

Children's capacity to agree to psychological research: knowledge of risks and benefits and voluntariness

A series of studies investigated the capacity of children between the ages of 7 and 12 to give free and informed consent to participation in psychological research. Children were reasonably accurate in describing the purpose of studies, but many did not understand the possible benefits or especially the possible risks of participating. In several studies children's consent was not affected by the knowledge that their parents had given their permission or by the parents saying that they would not be upset if the children refused. In contrast, other studies found that children were much more likely to stop their participation if the experimenter said explicitly that she would not be upset if they stopped. We suggest that experimenters should pay more attention to describing the possible risks and benefits of participation in research, and that they should also make it clearer to children that they are free to stop once they have begun.

Divergent effects of instructed and reported emotion regulation strategies on children’s memory for emotional information

ABSTRACT

Distraction can reduce adults’ memory for emotion-eliciting information, whereas reappraisal can preserve or enhance it. Yet, when given instructions to use specific emotion regulation (ER) strategies, adults report using other strategies too. The consequences of non-instructed strategy use within instructed ER paradigms are rarely examined. We investigated how both instructed and non-instructed but reported strategies related to memory for emotional information in childhood. Older (N?=?69; 8- to 10-year-olds; 24 girls) and younger (N?=?65; 5- to 7-year-olds; 35 girls) children received instructions to use cognitive distraction, reappraisal, or do nothing (control) before and after viewing a negative emotional film clip. Children were later interviewed about what they remembered about the film, and reported the ER strategies they used during it. Memory did not vary across instructed ER strategy conditions, and reported strategies did not relate to memory differently for older and younger children. Consistent with adult work, reported cognitive distraction related to poorer memory. Different reappraisal types were reported, but only situation-focused reappraisal was linked to better memory. In sum, children’s reported cognitive distraction and reappraisal strategies related to memory for emotional information differently. Thus, ER strategies divergently relate to what children remember about their emotional experiences.     

Adult credibility assessments of misinformed,deceptive and truthful children

This study compared how adults assess the credibility of children who either: (1) experienced a misleading suggestive interview, (2) were coached to lie or (3) experienced a non‐misleading interview. Preschool children (N = 24) were interviewed about a game they had played. One third of them spontaneously reported the truth, one third lied in response to coaching and one third spontaneously reported misinformation from a prior misleading suggestive interview. One hundred and twenty‐nine college students watched videotaped interviews of these children describing their alleged play activities and assessed their credibility. Children who had experienced misleading suggestive questioning were rated as less credible than those who were telling the truth and those who were lying. Adults could accurately detect truth‐telling children above chance, whereas accuracy was below chance detecting both lying children and children who had been misinformed. Adults were most confident of their ratings of truth‐telling children. Copyright © 2009 John Wiley & Sons, Ltd.     

Own and Others' Prior Experiences Influence Children's Imitation of Causal Acts

Young children learn from others' examples, and they do so selectively. We examine whether the efficacy of prior experiences influences children's imitation. Thirty-six-month-olds had initial experience on a causal learning task either by performing the task themselves or by watching an adult perform it. The nature of the experience was manipulated such that the actor had either an easy or a difficult experience completing the task. Next, a second adult demonstrated an innovative technique for completing it. Children who had a difficult first-person experience, and those who had witnessed another person having difficulty, were significantly more likely to adopt and imitate the adult's innovation than those who had or witnessed an easy experience. Children who observed another were also more likely to imitate than were those who had the initial experience themselves. Imitation is influenced by prior experience, both when it is obtained through one's own hands-on motor manipulation and when it derives from observing the acts of others.     

The effect of Russian versus Hebrew instructions on the reaction to social pressure of Russian-born Israeli children

An experiment on the role of the language of instruction in mediating responses to social pressure was conducted with a sample of 41 Russian-born adolescents who had recently immigrated to Israel. The subjects were asked to respond to a series of conflict situations in which they were told that either the experimenters, their own parents, or their peers would see their answers. Instructions were given once in Russian and once in Hebrew. Contrary to the principal hypothesis, when subjected to pressure from adults the children gave more conventional moral responses under Hebrew than under Russian instructions. The result was interpreted as reflecting the tendency to respond more moralistically to the language of authority, which, for the emigréchildren, shifted from Russian to Hebrew. Regardless of the language of administration, the scores for the emigréchildren fell between those for Soviet and Israeli youngsters, but they were closer to the latter. Within the sample, the longer a child lived in one or the other society, the more his response to social pressure resembled the modal reaction of children in that society. Children from families who had or had not spoken Yiddish in the home showed marked differences in response, with the former resembling the Israeli and the latter the typical Soviet reaction. The results were interpreted as reflecting the capacity of children to adapt to conflicting socialization settings both within and across cultures.
