Children's recognition of time in the causes and cures of physical and emotional reactions to illnesses and injuries

The present set of studies examined children's and college students' recognition of the role of time in the manifestation of causes and cures for illnesses and injuries. In Study 1, participants ranging from 4‐year‐olds through college students were presented with biological, moral, psychological, and irrelevant causes for illness symptoms and were asked how much time elapsed between the cause and the symptom. They were also asked if medicine would make the person feel better and if so how much time elapsed between taking the medicine and feeling better. Study 2 replicated Study 1 with 4‐ and 5‐year‐olds. Study 3 examined whether 4‐ and 5‐year‐olds and college students could differentiate between physical and emotional reactions to illnesses and injuries, with regard to time course. Overall, young children underestimate how long it takes for illness symptoms to emerge (expecting them to result right away following exposure to contamination). Nonetheless, children generated longer timelines for biological cures than biological causes. Moreover, 4‐ and 5‐year‐olds expect physical and emotional reactions to follow different time courses. These results suggest that young children have a nascent expectation that biological events are distinct from non‐biological events, in how they unfold over time.     

Preschoolers' understanding of germs as invisible mechanisms

Recent studies have presented conflicting claims regarding whether young children's reasoning about biological content involves a unique set of causal mechanisms and theoretical entities. Three studies examined preschoolers' understanding of nonobservable causal mechanisms in causes of illness. According to traditional accounts, these children know that certain behaviors lead to illness but have no idea why or how. Many of the behaviors children cite as causes are actually mediated by the action of germs (e.g., contamination and contagion). Do children recognize that germs (nonobvious, invisible particles) are the mechanisms involved in some cases of illness causation? Study 1 demonstrates that 4- and 5-year-olds' predictions of who will get sick in cases of contamination and contagion are based on the presence or absence of germs. Study 2 serves as a control and further tests how children generalize this mechanism: Which causes do children think are mediated by germs? Data suggest that preschoolers understand but undergeneralize the role of germs. A final study indicates that younger preschoolers (3-year-olds) recognize that appearances may be deceiving when it comes to judging causes of illness. This understanding would seem to be a precursor to beliefs about specific mechanisms. Results are discussed in terms of commonsense theories and early conceptions of biology.     

Children's understanding of physical illnesses and psychological states

Abstract

The present study set out to compare 5.7, and 9-year-old children's understanding of a physical illness (chicken pox) with their understanding of a psychological state (depression). In addition, information about personal experience of the illnesses and external sources of information was elicited, in order to assess the effects of both age and experience. Children at all ages showed a basic intact knowledge of both chicken pox and depression, although older children had a more sophisticated understanding of depression, and had acquired this knowledge from a greater number of sources. The clinical implications of the findings, and their relationship to both neo-Piagetian and more recent theories of conceptual development in childhood are discussed.     

Normative Social Role Concepts in Early Childhood

The current studies (N = 255, children ages 4–5 and adults) explore patterns of age‐related continuity and change in conceptual representations of social role categories (e.g., “scientist”). In Study 1, young children's judgments of category membership were shaped by both category labels and category‐normative traits, and the two were dissociable, indicating that even young children's conceptual representations for some social categories have a “dual character.” In Study 2, when labels and traits were contrasted, adults and children based their category‐based induction decisions on category‐normative traits rather than labels. Study 3 confirmed that children reason based on category‐normative traits because they view them as an obligatory part of category membership. In contrast, adults in this study viewed the category‐normative traits as informative on their own (not only as a cue to obligations). Implications for continuity and change in representations of social role categories will be discussed.     

Theory of mind and mental state discourse during book reading and story‐telling tasks

This article presents three studies conducted in Canada and Australia that relate theory of mind (ToM) development to mental state discourse. In Study 1, mental state discourse was examined while parents and their 5–7‐year‐old children jointly read a storybook which had a surprise ending about the identity of the main character. Comments specific to the mental states of the story characters and discourse after the book had ended were positively related to children's ToM, and this was due to parent elaborations. Studies 2 and 3 examined children's mental state discourse during story‐telling tasks, and in both, mental state discourse of children during narrative was concurrently related to ToM performance. While research has shown that mental state discourse of parents is related to children's ToM acquisition, the current research indicates that children's spontaneous use of mental state language examined outside of the interactional context is also a strong correlate.     

Domain‐Specificity of Creativity in Young Children: How Quantitative and Qualitative Data Support It

One of the most controversial issues in contemporary research of creativity, whether a person's creativity is domain‐specific or domain‐general, was investigated in the present study. This study is composed of two parts, Study 1 and Study 2. In study 1, the relationships among 109 children's creative performances in three domains, and the relationships between those children's general creative thinking skills and their creative performances in three domains have been examined. Study 2 examines how the domain‐specificity and ‐generality issue is addressed in individual children via case studies of three highly creative children, hoping to provide enriching and qualitative specification to the quantitative data of the present study. In both studies, children's performances in language, art, and math domains were respectively judged by three experts who rated children's creativity on story‐telling, collage making, and math word‐problem creating tasks. Children's general creative thinking skills were assessed by a battery of two divergent thinking tests, including the Wallach‐Kogan Creativity Test (Wallach & Kogan, 1965) and the Real World Divergent Thinking Test adapted from Okuda, Runco, and Berger (1991). The findings of this study support the position that creative ability in young children is rather (but not absolutely) domain‐specific.     

‘You Could Call It Magic’: What Parents and Siblings Tell Preschoolers About Unobservable Entities

How can we explain children's understanding of the unseen world? Young children are generally able to distinguish between real unobservable entities and fantastical ones, but they attribute different characteristics to and show less confidence in their decisions about fantastical entities generally endorsed by adults, such as Santa Claus. One explanation for these conceptual differences is that the testimony children hear from others about unobservable entities varies in meaningful ways. Although this theory has some experimental support, its viability in actual conversation has yet to be investigated. Study 1 sought to examine this question in parent–child conversation and showed that parents provide similar types of content information when talking to children about both real entities and entities that they generally endorse. However, parents use different pragmatic cues when they communicate about endorsed entities than they do when talking about real ones. Study 2 showed that older siblings used discourse strategies similar to those used by parents when talking to young children about unobservable entities. These studies indicate that the types of cues children use to form their conceptions of unobservable entities are present in naturalistic conversations with others, supporting a role for testimony in children's early beliefs.     

Children's conceptions of physical events: Explicit and tacit understanding of horizontal motion

The conceptual understanding that children display when predicting physical events has been shown to be inferior to the understanding they display when recognizing whether events proceed naturally. This has often been attributed to differences between the explicit engagement with conceptual knowledge required for prediction and the tacit engagement that suffices for recognition, and contrasting theories have been formulated to characterize the differences. Focusing on a theory that emphasizes omission at the explicit level of conceptual elements that are tacitly understood, the paper reports two studies that attempt clarification. The studies are concerned with 6‐ to 10‐year‐old children's understanding of, respectively, the direction (141 children) and speed (132 children) of motion in a horizontal direction. Using computer‐presented billiards scenarios, the children predicted how balls would move (prediction task) and judged whether or not simulated motion was correct (recognition task). Results indicate that the conceptions underpinning prediction are sometimes interpretable as partial versions of the conceptions underpinning recognition, as the omission hypothesis would imply. However, there are also qualitative differences, which suggest partial dissociation between explicit and tacit understanding. It is suggested that a theoretical perspective that acknowledges this dissociation would provide the optimal framework for future research.     

“They Danced Around in My Head and I Learned Them”: Children's Developing Conceptions of Learning

Two studies examined how 3–6-year-olds understand the process of learning. In study 1 examined how children spontaneously talk about learning via a CHILDES language analysis. Talk about the learning process increased between the ages of 3–5. Talk specifically about learning in terms of desire decreased during this period. This suggests the possibility that desire is important to children's initial understanding of learning, and children develop an understanding that various mental states including desire, attention, and intention, play a role in the learning process. In Study 2, we presented 4- and 6-year-olds with a set of stories designed to test their understanding of the role of these mental states. In both their judgments about whether someone learns and their justifications of their responses, younger children relied more on the character's desires whereas older children were more likely to integrate desire, attention, and intention together. These data suggest that children's understanding of the process of learning is developing during the early elementary school years.     

Understanding the glue of narrative structure: Children's on- and off-line inferences about characters’ goals

Because characters’ goals play a key role in the structure of narratives, the ability to make inferences about goals is essential to narrative comprehension. Despite their importance, no previous studies have examined the process by which children make these goal inferences. In the current study, we examined 6- and 8-year-old children's goal inference making processes through think-aloud protocols. We also examined the product of comprehension, the mental representation of text, through free recall and comprehension questions. The results revealed that children of both ages regularly made appropriate goal inferences while listening to narratives. In addition, the number of goal inferences predicted children's recall of the stories. Thus, children as young as 6 years old are sensitive to the vital role of characters’ goals in narrative structure, and they can engage in sophisticated cognitive processing while they listen to narratives to form coherent mental representations of them.     

The development of scientific knowledge of the Earth

Investigation of children's knowledge of the Earth can reveal much about the origins, content and structure of scientific knowledge, and the processes of conceptual change and development. Vosniadou and Brewer (1992 , claim that children construct coherent mental models of a flat, flattened, or hollow Earth based on a framework theory and intuitive constraints of flatness and support. To examine this account, 62 children, aged 5–10 years, and 31 adults ranked 16 pictures according to how well they were thought to represent the Earth. Even young children showed scientific knowledge of the shape of the Earth. There was little or no evidence of naïve mental models, indicating that any intuitions or constraints must be very weak. Instead, before they acquire the scientific view, children's knowledge of the Earth appears to be incoherent and fragmented.     

What do children learn about biology from factual information? A comparison of interventions to improve understanding of contagious illnesses

Background . Children have been shown to hold misconceptions about illness, and previous work has indicated that their knowledge can be improved through the use of interventions. Aims . This study aims to evaluate interventions based on the provision of factual information for improving understanding of contagious illness. Sample . The participants were 96 children from two age groups: 7 and 11 years. Methods . During the pre‐test, the children were asked about three contagious illnesses and one novel illness. There were three intervention conditions, differing in the level of factual information provided: explanations provided, no explanations provided and scientific factual style. The interventions were focused on contagious illnesses (cold, chickenpox). A post‐test was conducted 6 weeks later. Results . Results from the pre‐test show that the older children have more sophisticated understanding of illness than the younger children. Mean pre‐ to post‐test change was calculated and analyses revealed that there is greater pre‐ to post‐test change in the explanation and scientific fact conditions when compared with that in the no‐explanation condition. The improvements in knowledge generalized to other contagious illnesses, and the older children showed more improvements than the younger children. Conclusions . These findings add to the literature on children's understanding of contagious illnesses and contribute towards discussions on the best approach to health education.     

Explanatory models of illness: a study of within-culture variation

The current studies explore causal models of heart attack and depression generated from American healers whom use distinct explanatory frameworks. Causal chains leading to two illnesses, heart attack and depression, were elicited from participant groups: registered nurses (RNs), energy healers, RN energy healers, and undergraduates. The domain-specificity hypothesis predicted that psycho-social and physical causes would not interact in illness models. Across illnesses, RNs and undergraduates rarely cited interactions between mental and physical causes, consistent with the domain specificity hypothesis. In contrast, energy healers frequently mentioned interactions. Study 2 showed that these differences were not due to salience. These results suggest that domain-specificity theory is supported for groups with extensive exposure to western medicine but does not explain energy models of illness. Implications for other cultural models of illness are discussed.     

Children's Conceptions of Characteristic Features of Category Members

Abstract

The authors investigated children's conceptions of the characteristic features of category members and found that their conceptions underwent qualitative developmental changes. They hypothesized that (a) children initially tend to perceive category members in terms of individual characteristics (i.e., internal dispositions and behavioral patterns) and (b) only later do they conceive of category members in terms of their shared beliefs and values. They explored these hypotheses in 2 studies: In Study 1, they investigated how Protestant and Catholic children in Northern Ireland understood the religious intergroup context in their own country; in Study 2, children in Italy were presented with a fictional scenario of intergroup conflict and asked to explain the causes of the conflict. The results of both studies confirmed the 2 hypotheses.     

When the happy victimizer says sorry: Children's understanding of apology and emotion

Previous research suggests that children gradually understand the mitigating effects of apology on damage to a transgressor's reputation. However, little is known about young children's insights into the central emotional implications of apology. In two studies, children ages 4–9 heard stories about moral transgressions in which the wrongdoers either did or did not apologize. In Study 1, children in the no‐apology condition showed the classic pattern of ‘happy victimizer’ attributions by expecting the wrongdoer to feel good about gains won via transgression. By contrast, in the apology condition, children attributed negative feelings to the transgressor and improved feelings to the victim. In Study 2, these effects were found even when the explicit emotion marker ‘sorry’ was removed from the apology exchange. Thus, young children understand some important emotional functions of apology.     

Individual differences in children's understanding of inversion and arithmetical skill

Background and aims. In order to develop arithmetic expertise, children must understand arithmetic principles, such as the inverse relationship between addition and subtraction, in addition to learning calculation skills. We report two experiments that investigate children's understanding of the principle of inversion and the relationship between their conceptual understanding and arithmetical skills. Sample. A group of 127 children from primary schools took part in the study. The children were from 2 age groups (6–7 and 8–9 years). Methods. Children's accuracy on inverse and control problems in a variety of presentation formats and in canonical and non‐canonical forms was measured. Tests of general arithmetic ability were also administered. Results. Children consistently performed better on inverse than control problems, which indicates that they could make use of the inverse principle. Presentation format affected performance: picture presentation allowed children to apply their conceptual understanding flexibly regardless of the problem type, while word problems restricted their ability to use their conceptual knowledge. Cluster analyses revealed three subgroups with different profiles of conceptual understanding and arithmetical skill. Children in the ‘high ability’ and ‘low ability’ groups showed conceptual understanding that was in‐line with their arithmetical skill, whilst a 3rd group of children had more advanced conceptual understanding than arithmetical skill. Conclusions. The three subgroups may represent different points along a single developmental path or distinct developmental paths. The discovery of the existence of the three groups has important consequences for education. It demonstrates the importance of considering the pattern of individual children's conceptual understanding and problem‐solving skills.     

Children's representations of the earth: A methodological comparison

Investigation of children's understanding of the earth can reveal much about the origins and development of scientific knowledge. Vosniadou and Brewer (1992) claim that children construct coherent, theory‐like mental models of the earth. However, more recent research has indicated that children's knowledge of the earth is fragmented and incoherent. By testing the influence of question type (open vs. forced‐choice questions) and medium (drawings vs. 3‐D models) on the responses of 6‐year‐olds (N=59), this study investigated whether, and how, methodological differences account for the discrepant findings of previous research. Both the use of drawings and of open questions (Vosniadou and Brewer's methods) were found to increase the apparent incidence of naïve mental models. Moreover, the combination of 3‐D models and forced‐choice questions elicited more scientifically correct responses and higher proportions of scientific and inconsistent mental models than the combination of drawings and open questions. It is argued that children know more about the earth than the mental model theorists claim, and that naïve mental models of the earth are largely artifactual.     

Promoting Honesty: The Influence of Stories on Children's Lie‐Telling Behaviours and Moral Understanding

Moral stories are a means of communicating the consequences of our actions and emphasizing virtuous behaviour, such as honesty. However, the effect of these stories on children's lie‐telling has yet to be thoroughly explored. The current study investigated the influence of moral stories on children's willingness to lie for another individual. Children were read one of three stories prior to being questioned about an accidental wrongdoing: (1) a positive story, which emphasized the benefits of being honest; (2) a negative story, which outlined the potential costs of lying; and (3) a neutral story, which was unrelated to truth‐telling or lie‐telling. Initially, most children withheld information about the event. Older children were better able to maintain their lies throughout the interview. However, when asked direct questions, children in the positive story condition were more likely to tell the truth than those in the negative and neutral conditions. No significant differences were found between the negative and neutral story conditions. The present study also investigated the relationship between children's conceptual understanding and behaviour. The findings revealed that children's knowledge of truths and lies increased with age. Children who lied had significantly higher conceptual scores than those who did not lie. Furthermore, the type of story children were read had a significant impact on their evaluations of true and false statements. Copyright © 2015 John Wiley & Sons, Ltd.     

The Practices of Apostolic Faith Healers in Mental Health Care in Zimbabwe

This study aimed to understand and interpret faith healers' explanations of the aetiology and treatment of diseases and to canvass their views regarding collaboration between Western trained health care professionals and faith healers. Fifteen female and six male faith healers from Apostolic churches in Marondera (Zimbabwe) were selected and interviewed (mean age = 42.38 years; age range = 20–69 years). All the faith healers interviewed had been practising from two to fifty years. Content analysis of the data indicated that faith healers use a variety of procedures like prayer, holy water, counselling and sacred stones during their healing sessions. Common ailments brought to the faith healers included mental disorders, infertility, substance abuse, sleep disorders, childhood problems and physical problems. Witchcraft and avenging spirits were cited as the most common causes for illness. Closer cooperation between Western trained health practitioners and traditional (faith) healers is needed in the treatment of both physical and mental illnesses.     

Preschool‐aged children's understanding of gratitude: Relations with emotion and mental state knowledge

Developmental precursors to children's early understanding of gratitude were examined. A diverse group of 263 children was tested for emotion and mental state knowledge at ages 3 and 4, and their understanding of gratitude was measured at age 5. Children varied widely in their understanding of gratitude, but most understood some aspects of gratitude‐eliciting situations. A model‐building path analysis approach was used to examine longitudinal relations among early emotion and mental state knowledge and later understanding of gratitude. Children with a better early understanding of emotions and mental states understand more about gratitude. Mental state knowledge at age 4 mediated the relation between emotion knowledge at age 3 and gratitude understanding at age 5. The current study contributes to the scant literature on the early emergence of children's understanding of gratitude.
