Cross‐sectional and longitudinal relations between mother‐child talk about conflict and children's social understanding

We examined the relations between the ways 48 mothers and their 3‐ to 5‐year‐olds talked about a conflict depicted in a picture book and their children's current and subsequent level of social understanding. We distinguished explanatory talk, which directed attention to the actions that generated the conflict, from non‐explanatory talk, which discussed the conflict in terms of, for example, making up or saying sorry. Controlling for child age and overall talk by mother, explanatory talk was positively associated with contemporaneous social understanding. Social understanding at time one was also positively associated with social understanding 30 months later. These data suggest that dialogue about conflict may be helpful for 3‐ to 5‐year old children's understanding of the mental world, to the extent that it facilitates their understanding of particular social situations.     

A non‐human primate’s understanding of solidity: dissociations between seeing and acting

Studies often reveal a dissociation between what infants know as revealed by action and what they know as revealed by perception. We explored whether non‐human primates exhibit a similar dissociation, focusing on what rhesus macaques know about solidity. In a series of search experiments, Hauser (2001) found that rhesus do not possess a complete understanding of solidity, searching below a solid shelf for an invisibly displaced object. In the present experiments, we explored how rhesus would perform in expectancy violation versions of the same tasks. Subjects looked longer when an apple appeared to fall through a solid shelf and when it appeared to roll through a solid barrier. These results suggest that macaques have some understanding of solidity when tested using looking paradigms even though they do not appear to use this knowledge when searching for food. We speculate that this dissociation is similar to that demonstrated in human development.     

The roles of context and everyday experience in understanding work‐non‐work relationships: A qualitative diary study of white‐ and blue‐collar workers

The purpose of the study was to address several of the limitations of work‐non‐work research by adopting a qualitative diary methodology which explored insiders' accounts of both the positive and negative aspects of work‐non‐work relationships and examined the role of context in shaping such relationships. Daily diary data on work‐non‐work events and post‐diary interview data were collected from participants in two contrasting organizational contexts: Flexorg (N=20), a progressive local government organization and The Factory (N=18), a traditional manufacturing organization. Work‐non‐work relationships were found to be simultaneously enriching and depleting in both organizations. For Flexorg workers, work‐non‐work relationships were characterized by facilitation and time‐based conflicts. At The Factory, high spillover from work to non‐work and vice versa challenged the assumption that blue‐collar work is typified by segmentation ( Nippert‐Eng, 1995 ). The experience of work‐non‐work events was shaped by the nature of the work, the work‐non‐work culture and working patterns in both organizations. The study also identified negative spillover as a qualitatively more important problem than work‐non‐work conflict in this study, and identified a social dimension of work‐non‐work conflict which was found across organizational contexts.     

The relations between maternal behaviors and urban preschool children's internal working models of attachment security

Interviewed 93 African-American, low-income women who had become pregnant as teenagers and their preschool-aged children in their homes. Mothers answered questions regarding their everyday stresses and feelings of depression. Children were assessed for receptive vocabulary ability, then video-taped completing five stories thematically related to attachment experiences with mother and rated on their security of attachment. Mothers and children were also videotaped playing together, and mothers were assessed on their sensitivity to their children's cues. After controlling for children's age and receptive vocabulary ability, mothers' sensitivity significantly predicted children's level of attachment security. The positive association between maternal sensitivity and children's security of attachment, and the strengths and weaknesses of administering the Attachment Story-Completion Task in the home with this population, are discussed. Implications for assessing attachment in the home are considered.     

Young children's understanding of the context‐relativity of normative rules in conventional games

We investigated young children's awareness of the context‐relative rule structure of simple games. Two contexts were established in the form of spatial locations. Familiar objects were used in their conventional way at location 1, but acquired specific functions in a rule game at location 2. A third party then performed the conventional act at either of the two locations, constituting a mistake at location 2 (experimental condition), but appropriate at location 1 (control condition). Three‐year‐olds (but not 2‐year‐olds) systematically distinguished the two conditions, spontaneously intervening with normative protest against the third party act in the experimental, but not in the control condition. Young children thus understand context‐specific rules even when the context marking is non‐linguistic. These results are discussed in the broader context of the development of social cognition and cultural learning.     

Pre‐school children's understanding of the emotional consequences for failures to act prosocially

This study compares 4‐ and 5‐year‐old children's assessment of the emotional consequences of failures to act prosocially with their assessment of the emotional consequences for prosocial and victimization situations. After listening to stories illustrating each of the socio‐moral situations, children rated the emotional consequences for an actor, recipient and observing teacher and justified their ratings. Findings show that pre‐school children's emotion ratings for failures to act prosocially differed from their emotion ratings for prosocial and victimization behaviours. Preschool children's ratings of an actor's emotions depended on the presence or absence of an observing teacher in prosocial and victimization situations, but not in failures to act prosocially. This study illustrates the complexity of young children's reasoning about failures to act prosocially and highlights the importance of contextual influences on children's understanding of socio‐moral emotions.     

Self‐knowledge in childhood: Relations with children's imaginary companions and understanding of mind

Relations between interior self‐knowledge and (a) imaginary companion (IC) status and (b) theory of mind (ToM) abilities were investigated in a sample (N= 80) of 4‐ to 7‐year‐olds. Interior self‐knowledge was assessed in terms of the extent to which children acknowledged that they (rather than an adult) were the authority on unobservable aspects of themselves (e.g., dreaming, thinking, hunger). Compared with children without an IC, those who possessed a parentally corroborated IC ascribed less interior self‐knowledge to an adult, with a trend for them to assign more interior self‐knowledge to themselves. Children's interior self‐knowledge judgments were not associated with their ToM performance. IC status was also unrelated to ToM performance. We consider how having an IC may provide children with opportunities to distinguish between knowledge that is inaccessible to an external observer and that which an external observer may glean without being told.     

Children's understanding of their own and others' mental states. Part A. Self‐understanding precedes understanding of others in pretence

We examined 3‐ to 6‐year‐old children's attributions of pretence when their own or another's behaviours were characterized as similar (usually unintentionally) to that of a real or nonexistent animal. In some pretence tasks, we asked children if they were trying to look like or looked like the animal they were characterized as looking like; in others, if and how they could (or why they could not) pretend to be a real or nonexistent animal. Children at 4–6 years of age understood their own pretences better than another's pretences, but even by 6 years of age children continued to fail to understand pretence by another. Across ages children tended to be consistent in their claims about whether or not they looked liked (or were trying to look like) the animal, and whether or not they were pretending to be it. Children appear to take someone's merely looking like an animal as evidence that the person (whether self or other) is pretending to be that animal. Their success on self‐pretence tasks probably results from their unwillingness to believe that their own actions look like those of the animal because they had not intended to look like it.     

Self‐transcendence as a psychological parenthood motive: When mortality salience increases the desire for non‐biological children

Reminders of existential threat increase people's desire for offspring. In line with terror management theory, we explain these effects by the motivation to transcend the self via offspring that complements biological accounts of reproduction motivation under threat. Accordingly, Study 1 shows that mortality salience increases self‐transcendence motivation but not other parenthood motivations. Furthermore, mortality salience increased willingness to adopt children (Study 2) or a 14‐year‐old child (Study 3) only for those participants who were told that the personality of children is the product of nurture (and thus determined by their parent's self). In addition, mortality salience increased general willingness to adopt, irrespective of whether nurture or genetic influence was made salient in Study 3, where participants imagined being unable to have biological offspring. We discuss how these findings contribute to explaining increased reproduction intentions under existential threat and processes of terror management.     

Cogency,Warrant Transmission‐Increase and non‐Ideal Thinkers

Contemporary debates concerning warrant transmission take for granted this thesis: when warrant transmission fails the argument fails. I challenge this thesis. An argument with conclusion C, addressed to subject S, can be cogent in the sense that recognition that the premises entail (or make highly likely) C can rationally foster in S the belief in C, without the warrant for C necessarily being gained (or reinforced) by such recognition. A key idea is to accept that some arguments should be understood in a way that involves the abandonment of two characteristic idealizations imposed on rational thinkers by Bayesian modelling.     

Epistemic and non‐Epistemic Theories of Remembering

Contemporary memory sciences describe processes that are dynamic and constructive. This has led some philosophers to weaken the relationship between memory and epistemology; though remembering can give rise to epistemic success, it is not itself an epistemic success state. I argue that non‐epistemic (causal) theories will not do; they provide neither necessary nor sufficient conditions for remembering that p. I also argue that the shortcomings of the causal theory are epistemic in nature. Consequently, a theory of remembering must account for both its fundamentally epistemic nature and for its constructive and dynamic processes.     

Testing and modelling non‐normality within the one‐factor model

Maximum likelihood estimation in the one‐factor model is based on the assumption of multivariate normality for the observed data. This general distributional assumption implies three specific assumptions for the parameters in the one‐factor model: the common factor has a normal distribution; the residuals are homoscedastic; and the factor loadings do not vary across the common factor scale. When any of these assumptions is violated, non‐normality arises in the observed data. In this paper, a model is presented based on marginal maximum likelihood to enable explicit tests of these assumptions. In addition, the model is suitable to incorporate the detected violations, to enable statistical modelling of these effects. Two simulation studies are reported in which the viability of the model is investigated. Finally, the model is applied to IQ data to demonstrate its practical utility as a means to investigate ability differentiation.     

Effects of maternal negativity and of early and recent recurrent depressive disorder on children's false belief understanding

Research has shown that children of depressed mothers are at risk for problems in a variety of developmental domains; however, little is known about the effects of maternal depression on children's emerging understanding of false beliefs. In this study, 3 false belief tasks were administered to 5-year-old children whose mothers had either met criteria for major depressive disorder within the first 20 months of the child's life (n = 91) or had never been depressed (n = 50). Significant difficulties in performance were found among the children of depressed mothers, especially those whose mothers had experienced early and recent recurrent depressive disorder. Regardless of diagnostic status, children whose mothers exhibited negativity during problem-solving tasks administered at an earlier developmental period also were less likely to demonstrate false belief understanding. These effects remained even after child verbal ability was controlled.     

Two‐year‐olds’ understanding of self‐symbols

This study investigated 48 2.5‐year‐olds’ ability to map from their own body to a two‐dimensional self‐representation and also examined relations between parents’ talk about body representations and their children's understanding of self‐symbols. Children participated in two dual‐representation tasks in which they were asked to match body parts between a symbol and its referent. In one task, they used a self‐symbol and in the other they used a symbol for a doll. Participants were also read a book about body parts by a parent. As a group, children found the self‐symbol task more difficult than the doll‐task; however, those whose parents explicitly pointed out the relation between their children's bodies and the symbols in the book performed better on the self‐symbol task. The findings demonstrate that 2‐year‐old children have difficulty comprehending a self‐symbol, even when it is two‐dimensional and approximately the same size as them, and suggest that parents’ talk about self‐symbols may facilitate their understanding.     

Remote control and children's understanding of robots

Children use goal-directed motion to classify agents as living things from early in infancy. In the current study, we asked whether preschoolers are flexible in their application of this criterion by introducing them to robots that engaged in goal-directed motion. In one case the robot appeared to move fully autonomously, and in the other case it was controlled by a remote. We found that 4- and 5-year-olds attributed fewer living thing properties to the robot after seeing it controlled by a remote, suggesting that they are flexible in their application of the goal-directed motion criterion in the face of conflicting evidence of living thing status. Children can flexibly incorporate internal causes for an agent’s behavior to enrich their understanding of novel agents.     

Internet versus paper‐and‐pencil survey methods in psychological experiments: Equivalence testing of participant responses to health‐related messages

Despite experiments being increasingly conducted over the Internet, few studies have tested whether such experiments yield data equivalent to traditional methods' data. In the current study, data obtained via a traditional sampling method of undergraduate psychology students completing a paper‐and‐pencil survey (N = 107) were compared with data obtained from an Internet‐administered survey to a sample of self‐selected Internet‐users (N = 94). The data examined were from a previous study that had examined the persuasiveness of health‐related messages. To the extent that Internet data would be based on a sample at least as representative as data derived from a traditional student sample, it was expected that the two methodologies would yield equivalent data. Using formal tests of equivalence on persuasion outcomes, hypotheses of equivalence were generally supported. Additionally, the Internet sample was more diverse demographically than the student sample, identifying Internet samples as a valid alternative for future experimental research.     

Young children's understanding of desire formation

Two studies examined preschoolers' appreciation of how mental states arise. In Study 1, children aged 3 to 5 (24 at each age) better understood perception-generated beliefs (e.g., that looking in a certain location generates a belief about the location's content) and attitude-generated desires (e.g., that positive experiences with an activity generate a desire to partake of the activity again) than physiology-generated desires (e.g., that not eating for a long time generates a desire for food). In Study 2, 4- and 5-year-olds (48 at each age) better understood the effects of quantity of experience (e.g., eating a lot vs. a little) than of time of experience (eating just now vs. a long time ago) on physiological states and desires. The findings suggest that whether children reason in more advanced fashion about desires or beliefs depends on which aspects of these mental states are considered.     

Preschool children's understanding of causal connections

Preschool-aged children's understanding of causal mechanism was assessed by showing them a simple event sequence in which two objects moved in tandem. The central question was whether children would infer the presence of a mechanism linking the two objects whose movement covaried. This was tested by assessing five responses: actions when asked to move one object, explanations for how the object moved, predictions as to whether both objects would still move without a connection, inferences about the nature and location of the connection, and surprise when the objects moved without any apparent connection. The results from 3-, 4- and 5-year-olds indicated that an understanding of mechanism is firmly established by 5 years but fragile at 3 years and only revealed by some response modes. The implications of the results concerning how to characterize and test for early competence are discussed.     

Children's moral judgments of commission and omission based on their understanding of second‐order mental states1

Abstract: Children's moral judgments about acts of commission and omission with negative outcomes were studied based on their understanding of mental states. Children (N = 142) in the first, third, and fifth grades made judgments about four tasks composed of two levels of mental states (first‐order or second‐order) and two types of acts (commission or omission). The results showed that the 7‐year‐olds responded considering only first‐order mental states, but the 9‐ and 11‐year‐olds also used second‐order mental states in their judgments. Whether the acts were commission or omission did not make a difference. These results indicate that children can make moral judgments regarding acts of commission and omission based on an understanding of second‐order mental states by approximately the age of 9 years.
