Stick to the script: The effect of witnessing multiple actors on children’s imitation

What kinds of cues increase imitative fidelity in early childhood? The effects of multiple models and verbal framing were examined in preschool children (N = 259, 3–6-year-olds). Each participant was presented with one of eight possible combinations of type of modeling and verbal frame. The type of modeling involved: (i) a single model offering two demonstrations, (ii) two successive models each offering a single demonstration, (iii) two synchronous models each offering two demonstrations, or (iv) two synchronous models each offering a single demonstration. The verbal frame preceding the demonstrations emphasized either the instrumental outcome of the actions or their conventionality. Imitative fidelity was highest for the synchronous models (types iii and iv) and lowest for the single model (type i). Imitative fidelity was also higher for the convention-oriented than the outcome-oriented frame and higher for older than younger children. Children also provided more conventional explanations for their actions after viewing the synchronous models and after the convention-oriented framing. The results indicate that children’s imitative fidelity depends on the number of actors and the way the actions are framed.     

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.     

"Don't try this at home": toddlers' imitation of new skills from people on video

Imitation of people on educational television is a potential way for very young children to learn new skills. Although toddlers in previous studies exhibited a “video deficit” in learning, 24-month-olds in Study 1 successfully reproduced behaviors modeled by a person who was on video as well as they did those modeled by a person who was present in the room (even after a 24-h delay). Neither displaced filming context nor cuts between actions affected toddlers’ imitation from video. Shortening the demonstration in Study 2 affected imitation in the video condition but not in the live condition. In Study 3, 24-month-olds who viewed the original longer videos on their family TV screens (with which they had a viewing history) imitated significantly less than those who viewed the videos on the laboratory monitor. Imitation of a live modeler was the same across settings (home or lab). Implications for toddlers’ judgments of reliable information sources and for the design of educational television programs are discussed.     

Evolutionary perspectives on imitation: is a comparative psychology of social learning possible?

Studies of imitation in animals have become numerous in recent times, but do they contribute to a comparative psychology of social learning? We review this burgeoning field to identify the problems and prospects for such a goal. Difficulties of two main kinds are identified. First, researchers have tackled questions about social learning from at least three very different theoretical perspectives, the "phylogenetic", "animal model", and "adaptational". We examine the conflicts between them and consider the scope for integration. A second difficulty arises in the methodological approaches used in the discipline. In relation to one of these - survey reviews of published studies - we tabulate and compare the contrasting conclusions of nine articles that together review 36 studies. The basis for authors' disagreements, including the matters of perceptual opacity, novelty, sequential structure, and goal representation, are examined. In relation to the other key method, comparative experimentation, we identify 12 studies that have explicitly compared species' imitative ability on similar tasks. We examine the principal problems of comparing like with like in these studies and consider solutions, the most powerful of which we propose to be the use of a systematic range of task designs, rather than any single "gold standard" task.     

Anti-equality: Social comparison in young children

Young children dislike getting less than others, which might suggest a general preference for equal outcomes. However, young children are typically not averse to others receiving less than themselves. These results are consistent with two alternatives: young children might not have any preferences about others receiving less than themselves, or they might have preferences for others receiving less than themselves. We test these alternatives with 5- to 10-year-old children. We replicate previous findings that children will take a cost to avoid being at a relative disadvantage, but also find that 5- and 6-year-olds will spitefully take a cost to ensure that another’s welfare falls below their own. This result suggests that the development of fairness includes overcoming an initial social comparison preference for others to get less relative to oneself.     

A Dollar Is a Dollar Is a Dollar,or Is It? Insights From Children's Reasoning About “Dirty Money”

Money can take many forms—a coin or a bill, a payment for an automobile or a prize for an award, a piece from the 1989 series or the 2019 series, and so on—but despite this, money is designed to represent an amount and only that. Thus, a dollar is a dollar, in the sense that money is fungible. But when adults ordinarily think about money, they think about it in terms of its source, and in particular, its moral source (e.g., dirty money). Here we investigate the development of the belief that money carries traces of its moral history. We study children ages 5–6 and 8–9, who are sensitive to both object history and morality, and thus possess the component pieces needed to think that a dollar may not be like any other. Across three principal studies (and three additional studies in Appendix S1 ; N = 327; 219 five- and six-year-olds; 108 eight- and nine-year-olds), we find that children are less likely to want money with negative moral history, a pattern that was stronger and more consistent among 8- and 9-year-olds than 5- and 6-year-olds. These findings highlight pressing directions for future research that could help shed light on the mechanisms that contribute to the belief that money carries traces of its moral history.     

A case of hand waving: Action synchrony and person perception

While previous research has demonstrated that people’s movements can become coordinated during social interaction, little is known about the cognitive consequences of behavioral synchrony. Given intimate links between the systems that regulate perception and action, we hypothesized that the synchronization of movements during a dyadic interaction may prompt increased attention to be directed to an interaction partner, hence facilitate the information that participants glean during a social exchange. Our results supported this prediction. Incidental memories for core aspects of a brief interaction were facilitated following in-phase behavioral synchrony. Specifically, participants demonstrated enhanced memory for an interaction partner’s utterances and facial appearance. These findings underscore the importance of action perception to social cognition.     

Verbal imitation is based on intention understanding

Using an elicited imitation paradigm, we investigated whether young children imitate the communicative intentions behind speech. Previous research using elicited imitation has shown that children tend to correct ungrammatical sentences. This finding is usually interpreted as evidence that children, like adults, remember and reproduce the gist of linguistic information. In three studies, we tested whether this tendency is also a product of their intention understanding. Replicating and extending previous research by Meltzoff [Meltzoff A. N. (1995). Understanding the intentions of others: Re-enactment of intended acts by 18-month-old children. Developmental Psychology, 31, 838–850], our first two experiments showed that children tend to correct ungrammatical sentences. A critical third experiment showed that children correct ungrammatical sentences only when they believe the model to be an intentional agent. These results complement previous findings from the action domain and strongly support the claim that imitation is based on understanding the intentions of others.     

Looking good versus doing good: which factors take precedence when children learn about new tools?

We present two experiments exploring whether individuals would be persuaded to imitate the intentional action of an adult model whose actions suggest that the correct way to complete a task is with an inefficient tool. In Experiment 1, children ages 5–10 years and a group of adults watched an adult model reject an efficient tool in favor of one that was inefficient, but claim it was “made for” the task. Results indicated low rates of imitation of the model’s intentional choice until 9 and 10 years of age. In Experiment 2, children ages 3–11 years again watched a model reject a functional tool in favor of a nonfunctional one. This time, the demonstration took place on video. For half of the participants, the model from the video was present to offer a choice between the two tools (high-pressure condition), and for the other half, she was absent (low-pressure condition). Children also completed a social desirability questionnaire to explore relationships between imitation choices and personality. Results indicated that rates of imitation were associated with higher scores on the social desirability scale among children ages 3–7 years. Among 8- to 11-year-olds – and especially among 9- and 10-year-olds – the decision to copy the model’s intentional choice was more likely when the model was present than when she was absent. The findings reveal the contributions of age, personality, and social pressure to differences in imitation.     

The development of a trait measure of ruminative thought

A 9-item questionnaire was designed to measure rumination. This questionnaire measures three distinct facets of rumination: emotionality, motivation, and distraction. Together, these factors measure the extent to which people engage in thoughts regarding their progress toward their goals. In Study 1, an exploratory factor analysis of an initial 28 items was used to reveal the underlying structure of the rumination construct. In Study 2, a confirmatory factor analysis revealed support for the hypothesized factor structure proposed by Study 1. Following the suggestions of PROC CALIS (SAS) for model modification, an acceptable model was found that retained 9 items (3 on each factor). Studies 3 and 4 demonstrate the predictive validity of the rumination inventory. Study 3 provides evidence of a correlation between distraction by ruminative thoughts and low scores on a statistics examination. Study 4 shows a negative correlation between distraction by ruminative thoughts and time taken to learn to solve a geometric puzzle.     

Making tools isn't child's play

Tool making evidences intelligent, flexible thinking. In Experiment 1, we confirmed that 4- to 7-year-olds chose a hook tool to retrieve a bucket from a tube. In Experiment 2, 3- to 5-year-olds consistently failed to innovate a simple hook tool. Eight-year-olds performed at mature levels. In contrast, making a tool following demonstration was easy for even the youngest children. In Experiment 3, children’s performance did not improve given the opportunity to manipulate the objects in a warm-up phase. Children’s tool innovation lags substantially behind their ability to learn how to make tools by observing others.     

从表征和认知过程上看表象与知觉、记忆的关系

表象、知觉和记忆是一个整合的认知系统。由于知觉和记忆提供了表象生成的材料,因而三者共享相似的表征,并激活广泛而相似的脑区。然而在认知加工过程上三者存在一定的差异。与知觉相比,表象的编码方式更抽象、更依赖过去经验的参与且处理细节能力更弱;与记忆相比,表象更容易受无关信息的干扰。未来对三者关系的研究应关注不同来源和不同类型的表象与知觉、记忆之间的关系,以及工作记忆在三者关系中所起的作用。     

Can bad weather improve your memory? An unobtrusive field study of natural mood effects on real-life memory

Can good or bad mood induced by the weather influence people’s ability to correctly remember everyday scenes? In this unobtrusive field study, we predicted and found that weather-induced negative mood improved memory accuracy. Randomly selected shoppers on bright, sunny days (good mood) or on cloudy, rainy days (bad mood) saw 10 unusual objects in the check-out area of a suburban shop, and their recall and recognition memory for these objects was later tested. Shoppers in a negative mood showed better memory and higher discrimination ability. The cognitive mechanisms responsible for everyday mood effects on memory performance are discussed, and the implications of these findings for current affect/cognition theories and applied areas are considered.     

The influence of electronic sound effects on learning from televised and live models

Infants rapidly accrue information via imitation from multiple sources, including television and electronic toys. In two experiments, we examined whether adding sound effects to video or live demonstrations would influence imitation by 6-, 12-, and 18-month-olds. In Experiment 1, we added matching and mismatching sound effects to target actions presented by a televised model. We found that 6-month-olds reproduced the target actions regardless of whether the sound effects were matched or mismatched, whereas 12- and 18-month-olds reproduced the actions only when the sound effects were matched. In Experiment 2, we added matching sound effects to target actions presented by a live model. The addition of sound effects disrupted imitation performance by 6-, 12-, and 18-month-olds. Overall, imitation provides a clear behavioral measure of rapid changes in learning from television and electronic toys during infancy. These findings have practical implications for producers and parents regarding learning in the digital age and theoretical implications regarding the development of integrated action-perception representational systems.     

Memory and interpretation of visual representations of threat in socially anxious and nonanxious individuals

The present study was designed to replicate and extend results reported by Brendle and Wenzel (Behav. Res. Ther. 42 (2004) 155), who found that socially anxious individuals accurately recalled threat-relevant information but subsequently imposed a biased interpretation upon that same material, using more ecologically valid stimuli. Socially anxious (n=37) and nonanxious (n=47) individuals viewed two positive, two negative, and two neutral video vignettes and completed two cognitive tasks assessing memory and interpretation of factual details immediately and after 48 h. Similar to the results reported by Brendle and Wenzel (2004), socially anxious and nonanxious individuals did not differ in their memory for details that had been presented in the vignettes. However, socially anxious individuals made more negative interpretations of details included in the vignettes than nonanxious individuals, although unlike Brendle and Wenzel (2004), they did not demonstrate the tendency to make less positive interpretations. It is concluded that socially anxious individuals are characterized by interpretation biases when presented with threat-relevant information, and there is no evidence to suggest that they are characterized by memory biases for threat-relevant information.
