Development of representational theory of mind: Concepts of mental states, awareness of thinking, and self-permanence.

In a recent monograph, my students, colleagues, and I reported on a comprehensive set of tests of the theory of Perceptual Access Reasoning (PAR), a new theory of the development of representational theory of mind (ToM). The central tenet of the theory is that young children acquire a hitherto undetected non-representational ToM (i.e., PAR), the use of which allows them to pass standard false belief tasks without understanding false beliefs. Thus, PAR theory capitalizes on an unrecognized flaw in all standard false belief tasks. In what follows, I present an overview of PAR theory, the tests that we have conducted of the theory, and logical arguments for how PAR explains the classic findings in the ToM literature. Next, I evaluate two recent alternate accounts that have been offered by critics, and I discuss some of the issues raised by three invited commentaries on the monograph. Finally, I consider the question, "What is the development of representational ToM the development of?" Insights from philosophy of mind point to the primacy of children's understanding of mental states in themselves, leading to a new concept of self-permanence that can provide the basis for a unified theory of the development of children's understanding of the mental and physical worlds. As a final thought, I consider how PAR was able to hide in plain sight for so long.

Perceptual Access Reasoning (PAR) in Developing a Representational Theory of Mind.

An important part of children's social and cognitive development is their understanding that people are psychological beings with internal, mental states including desire, intention, perception, and belief. A full understanding of people as psychological beings requires a representational theory of mind (ToM), which is an understanding that mental states can faithfully represent reality, or misrepresent reality. For the last 35 years, researchers have relied on false-belief tasks as the gold standard to test children's understanding that beliefs can misrepresent reality. In false-belief tasks, children are asked to reason about the behavior of agents who have false beliefs about situations. Although a large body of evidence indicates that most children pass false-belief tasks by the end of the preschool years, the evidence we present in this monograph suggests that most children do not understand false beliefs or, surprisingly, even true beliefs until middle childhood. We argue that young children pass false-belief tasks without understanding false beliefs by using perceptual access reasoning (PAR). With PAR, children understand that seeing leads to knowing in the moment, but not that knowing also arises from thinking or persists as memory and belief after the situation changes. By the same token, PAR leads children to fail true-belief tasks. PAR theory can account for performance on other traditional tests of representational ToM and related tasks, and can account for the factors that have been found to correlate with or affect both true- and false-belief performance. The theory provides a new laboratory measure which we label the belief understanding scale (BUS). This scale can distinguish between a child who is operating with PAR versus a child who is understanding beliefs. This scale provides a method needed to allow the study of the development of representational ToM. In this monograph, we report the outcome of the tests that we have conducted of predictions generated by PAR theory. The findings demonstrated signature PAR limitations in reasoning about the mind during the ages when children are hypothesized to be using PAR. In Chapter II, secondary analyses of the published true-belief literature revealed that children failed several types of true-belief tasks. Chapters III through IX describe new empirical data collected across multiple studies between 2003 and 2014 from 580 children aged 4-7 years, as well as from a small sample of 14 adults. Participants were recruited from the Phoenix, Arizona metropolitan area. All participants were native English-speakers. Children were recruited from university-sponsored and community preschools and daycare centers, and from hospital maternity wards. Adults were university students who participated to partially fulfill course requirements for research participation. Sociometric data were collected only in Chapter IX, and are fully reported there. In Chapter III, minor alterations in task procedures produced wide variations in children's performance in 3-option false-belief tasks. In Chapter IV, we report findings which show that the developmental lag between children's understanding ignorance and understanding false belief is longer than the lag reported in previous studies. In Chapter V, children did not distinguish between agents who have false beliefs versus agents who have no beliefs. In Chapter VI, findings showed that children found it no easier to reason about true beliefs than to reason about false beliefs. In Chapter VII, when children were asked to justify their correct answers in false-belief tasks, they did not reference agents' false beliefs. Similarly, in Chapter VIII, when children were asked to explain agents' actions in false-belief tasks, they did not reference agents' false beliefs. In Chapter IX, children who were identified as using PAR differed from children who understood beliefs along three dimensions-in levels of social development, inhibitory control, and kindergarten adjustment. Although the findings need replication and additional studies of alternative interpretations, the collection of results reported in this monograph challenges the prevailing view that representational ToM is in place by the end of the preschool years. Furthermore, the pattern of findings is consistent with the proposal that PAR is the developmental precursor of representational ToM. The current findings also raise questions about claims that infants and toddlers demonstrate ToM-related abilities, and that representational ToM is innate.

Reciprocal Relations between Emerging Adults' Representations of Relationships with Mothers, Fathers, and Romantic Partners.

This study employed a fully cross-lagged, longitudinal model to examine reciprocal relations between representations of relationships with parents and romantic partners at ages 20 and 22. Representations were assessed with continuous measures of dismissing/avoidant and preoccupied relationship styles across the attachment and affiliation systems for parents, and across the attachment, affiliation, and caregiving systems for romantic partners. Earlier relationships with both mothers and fathers independently predicted changes in later views of romantic relationships, and earlier romantic relationships predicted changes in later views of relationships with both mothers and fathers. This evidence of a developmental system of interconnected representations across relationships has theoretical implications about the nature of working models, and practical implications alerting parents to the onset of dating as a potentially fertile context for changes in their relationships with children.

Este estudio utilizó un modelo longitudinal de referencias plenamente cruzadas para examinar relaciones recíprocas entre representaciones de relaciones con padres y parejas románticas en las edades de 20 y 22. Se evaluaron las representaciones con medidas continuas de estilos de relaciones tipo desdeñoso-evasivo y tipo preocupado a través de los sistemas de apego y afiliación para padres, y a través de los sistemas de apego, afiliación y cuidado para parejas románticas. Las relaciones anteriores tanto con las madres como con los padres predijeron independientemente cambios en las opiniones ulteriores de relaciones románticas, mientras que las relaciones románticas anteriores predijeron cambios en las opiniones ulteriores tanto de las madres como de los padres. Esta evidencia de un sistema de desarrollo de representaciones interconectadas a través de relaciones tiene implicaciones teóricas acerca de la naturaleza de los modelos de trabajo e implicaciones prácticas que advierten a los padres que el inicio del periodo de salir en citas es potencialmente un contexto fértil para cambios en sus relaciones con los niños.

The unique effects of maternal and paternal depressive symptoms on youth's symptomatology: Moderation by family ethnicity, family structure, and child gender.

Drawing on five waves of longitudinal data from 392 families (52% female; mean age of wave 1 [Mage_W1] = 12.89, standard deviation [SD] = .48; Mage_W5 = 21.95, SD = .77; 199 European American and 193 Mexican American families; 217 intact and 175 stepfather families), this study documented transactional relations of mothers' and fathers' depressive symptoms with youth's symptomatology from early adolescence to young adulthood. Trait and time-varying cross-lagged models revealed that both mothers' and fathers' between- and within-person differences in depressive symptoms were associated with youth's internalizing and externalizing symptoms. Whereas each parent's depressive symptoms uniquely contributed to youth's internalizing symptoms, however, only mothers' depressive symptoms influenced youth's externalizing symptoms. Although reciprocal effects of youth's internalizing symptoms on parents' depressive symptoms were not significant, youth's externalizing symptoms predicted changes in mothers' depressive symptoms over time. Moderation analyses revealed distinct transactional patterns by family ethnicity and child gender, but not by family structure. This study revealed dynamic transactions among family members' symptomatology that point to opportune times and targets for intervention efforts aimed at mitigating the negative impact of parents' depressive symptoms on youth's adjustment.

Data Harmonization: Establishing Measurement Invariance across Different Assessments of the Same Construct across Adolescence.

Longitudinal measurement invariance is a major concern for developmental scholars who seek to evaluate the same underlying construct across time. Unfortunately, discontinuities in the expression of various psychological constructs, as well as essential changes in measurement that are necessitated by shifting developmental capacities and practice effects over time, make the task of establishing longitudinal invariance extremely difficult. Drawing on 5 waves of longitudinal data from 392 families (52% female; Mage_W1 = 12.89, SD = .48; Mage_W5 = 21.95, SD = .77; 199 European American and 193 Mexican American families), the current investigation sought to establish measurement invariance across developmentally appropriate changes in measures of depressive symptomatology from early adolescence through early adulthood. Using a combination of item parceling and the common and unique items from 2 assessment instruments for depressive symptoms, the data supported strong factorial invariance in youth's depressive symptoms across 5 waves of measurement. Findings suggest that traditional invariance approaches can be adapted to determine whether the same construct underlies different measurement instruments across time. This analytic strategy can allow researchers and clinicians to use more sophisticated techniques to understand changes in symptomatology regardless of changes in measurement or developmental capacity. Applying this approach to model patterns of depressive symptomatology from early adolescence to early adulthood has important clinical implications for elucidating periods when youth experience elevations in depressive symptoms and heightened needs for intervention services.

Associations between Parental Relocation Following Separation in Childhood and Maladjustment in Adolescence and Young Adulthood.

Petitions by custodial parents to relocate children away from non-custodial parents present difficult choices for family courts. In the current study, the sample (N = 81) was randomly recruited through the children's schools according to the following criteria: Children were 12 years old and at the time resided primarily with their mothers; mothers had been living with a male partner "acting in a father role" for at least the previous year. Thirty-eight children had been separated by more than an hour's drive from their biological fathers due to either their mothers or fathers relocating. The data were collected from two reporters (children and mothers) at five time points (child ages 12.5, 14, 15.5, 19.5, and 22) by trained interviewers using standardized measures with adequate reliability and validity. Long-distance separation from biological fathers prior to age 12 was linked in adolescence and young adulthood to serious behavior problems, anxiety and depression symptoms, and disturbed relationships with all three parental figures (i.e., biological fathers, mothers, and step-fathers). These associations held after controlling for mother-stepfather conflict and domestic violence, mothers' family income, and mother-biological father relationship quality. These longitudinal findings over time replicated the cross-sectional findings of Braver, Ellman, and Fabricius (2003) and Fabricius and Braver (2006). Policy implications for parental long-distance relocation following separation are discussed.

Introspection Plays an Early Role in Children's Explicit Theory of Mind Development.

This study assessed children's (N = 236) ability to introspect the mental states of seeing and knowing relative to their ability to attribute each state to others. Children could introspect seeing 10 months before they could introspect knowing. Two- and 3-year-olds correctly reported their own seeing states, whereas 3- and 4-year-olds correctly reported their own knowing states. For each mental state, there was a 7-month difference before children could correctly attribute that state to another. These findings indicate that knowing is more difficult to introspect than seeing and that the ability to introspect each mental state emerges prior to the ability to correctly attribute them to others. Theoretical implications for self-other differences in theory-of-mind development are considered.

Parenting and later substance use among Mexican-origin youth: Moderation by preference for a common language.

The primary goal of the current study was to test whether parent and adolescent preference for a common language moderates the association between parenting and rank-order change over time in offspring substance use. A sample of Mexican-origin 7th-grade adolescents (Mage = 12.5 years, N = 194, 52% female) was measured longitudinally on use of tobacco, alcohol, and marijuana. Mothers, fathers, and adolescents all reported on consistent discipline and monitoring of adolescents. Both consistent discipline and monitoring predicted relative decreases in substance use into early adulthood but only among parent-offspring dyads who expressed preference for the same language (either English or Spanish). This moderation held after controlling for parent substance use, family structure, having completed schooling in Mexico, years lived in the United States, family income, and cultural values. An unintended consequence of the immigration process may be the loss of parenting effectiveness that is normally present when parents and adolescents prefer to communicate in a common language.

Father-adolescent engagement in shared activities: Effects on cortisol stress response in young adulthood.

Parent-child relationships can critically affect youth physiological development. Most studies have focused on the influence of maternal behaviors, with little attention to paternal influences. The current study investigated father engagement with their adolescents in household (shopping, cooking) and discretionary leisure activities as a predictor of youth cortisol response to a challenging interpersonal task in young adulthood. The sample (N = 213) was roughly divided between Mexican American (MA; n = 101) and European American (EA; n = 112) families, and included resident biological-father (n = 131) and resident stepfather families (n = 82). Salivary cortisol was collected before, immediately after, and at 20 and 40 min after an interpersonal challenge task; area under the curve (AUCg) was calculated to capture total cortisol output. Results suggested that more frequent father engagement in shared activities with adolescents (ages 11-16), but not mother engagement, predicted lower AUCg cortisol response in young adulthood (ages 19-22). The relation remained significant after adjusting for current mother and father engagement and current mental health. Further, the relation did not differ given family ethnicity, father type (step or biological), or adolescent sex. Future research should consider unique influences of fathers when investigating the effects of parent-child relationships on youth physiological development and health. (PsycINFO Database Record

Development of constructivist theory of mind from middle childhood to early adulthood and its relation to social cognition and behavior.

Two studies examined the development of constructivist theory of mind (ToM) during late childhood and early adolescence. In Study 1, a new measure was developed to assess participants' understanding of the interpretive and constructive processes embedded in memory, comprehension, attention, comparison, planning, and inference. Using this measure, Study 2 tested a mediational model in which prosocial reasoning about conflict mediated the relation between constructivist ToM and behavior problems in high school. Results showed that the onset of constructivist ToM occurs between late childhood and early adolescence and that adolescents who have more advanced constructivist ToM have more prosocial reasoning about conflict, which in turn mediated the relation with fewer serious behavior problems in high school, after controlling for academic performance and sex. In both studies, girls showed more advanced constructivist ToM than boys in high school.

Effects of the interparental relationship on adolescents' emotional security and adjustment: The important role of fathers.

We examined the mediational roles of multiple types of adolescents' emotional security in relations between multiple aspects of the interparental relationship and adolescents' mental health from ages 13 to 16 (N = 392). General marital quality, nonviolent parent conflict, and physical intimate partner violence independently predicted mental health. Security in the father-adolescent relationship, over and above security with the mother and security in regard to parent conflict, mediated the link from general marital quality to adolescents' mental health. With 2 exceptions, paths were stable for boys and girls, biological- and stepfathers, and Anglo- and Mexican Americans. The findings reveal the need to expand the traditional foci on parent conflict and relationships with mothers to include general marital quality and relationships with fathers.

Reconsidering the "acculturation gap" narrative through an analysis of parent-adolescent acculturation differences in Mexican American families.

Using a sample of 193 Mexican American adolescents (M age at Wave 1 = 14) and three waves of data over two years, this study longitudinally examined the effects of parent-youth acculturation differences, relative to no differences, on parent-adolescent relationship quality and youth problem behavior. We examined parent-youth differences in overall acculturation, Mexican acculturation, and American acculturation. We differentiated between cases in which the adolescent was more acculturated than the parent and cases in which the parent was more acculturated than the adolescent. Adolescents were more commonly similar to their parents than different. Where differences existed, adolescents were not uniformly more American than their parents, no type of difference was associated with parent-adolescent relationship quality, and no type of difference in overall acculturation was associated with youth problem behavior. One type of difference by dimension (adolescent had less Mexican acculturation than mother) was associated with less risk of problem behavior.

He Said What? Guided Cognitive Reframing About the Co-resident Father/Stepfather-adolescent Relationship.

We studied young adolescents' seeking out support to understand conflict with their co-resident fathers/stepfathers and the cognitive and affective implications of such support-seeking, phenomena we call guided cognitive reframing. Our sample included 392 adolescents (Mage = 12.5, 52.3% female) who were either of Mexican or European ancestry and lived with their biological mothers and either a stepfather or a biological father. More frequent reframing was associated with more adaptive cognitive explanations for father/stepfather behavior. Cognitions explained the link between seeking out and feelings about the father/stepfather and self. Feelings about the self were more strongly linked to depressive symptoms than cognitions. We discuss the implications for future research on social support, coping, guided cognitive reframing, and father-child relationships.

Marital problems, maternal gatekeeping attitudes, and father-child relationships in adolescence.

We evaluated maternal gatekeeping attitudes as a mediator of the relation between marital problems and father-child relationships in 3 waves when children were in Grades 7-10. We assessed each parent's contribution to the marital problems experienced by the couple. Findings from mediational and cross-lagged structural equation models revealed that increased marital problem behaviors on the part of mothers at Wave 1 predicted increased maternal gatekeeping attitudes at Wave 2, which in turn predicted decreased amounts of father-adolescent interaction at Wave 3. Decreased amounts of interaction with either parent were associated within each wave with adolescents' perceptions that they mattered less to that parent. Amount of interaction with fathers at Wave 2 positively predicted changes in boys' perceptions of how much they mattered to their fathers at Wave 3, and amount of interaction with mothers at Wave 2 positively predicted changes in girls' perceptions of how much they mattered to their mothers at Wave 3. The findings did not differ for European American versus Mexican American families or for biological fathers versus step-fathers.

Guided cognitive reframing of adolescent-father conflict: who Mexican American and European American adolescents seek and why.

Adolescents may seek to understand family conflict by seeking out confidants. However, little is known about whom adolescents seek, whether and how such support helps youth, and the factors that predict which sources are sought. This chapter offers a conceptual model of guided cognitive reframing that emphasizes the behavioral, cognitive, and affective implications of confidant support as well as individual, family, and cultural factors linked to support seeking. The authors present empirical data from 392 families of seventh graders of Mexican and European ancestry to predict whether adolescents seek mothers, coresident fathers, and other sources and provide directions for subsequent research.

Patterns of Father Self Evaluations among Mexican and European American Men and Links to Adolescent Adjustment.

A mixed-method study identified profiles of fathers who mentioned key dimensions of their parenting and linked profile membership to adolescents' adjustment using data from 337 European American, Mexican American and Mexican immigrant fathers and their early adolescent children. Father narratives about what fathers do well as parents were thematically coded for the presence of five fathering dimensions: emotional quality (how well father and child get along), involvement (amount of time spent together), provisioning (the amount of resources provided), discipline (the amount and success in parental control), and role modeling (teaching life lessons through example). Next, latent class analysis was used to identify three patterns of the likelihood of mentioning certain fathering dimensions: an emotionally-involved group mentioned emotional quality and involvement; an affective-control group mentioned emotional quality, involvement, discipline and role modeling; and an affective-model group mentioned emotional quality and role modeling. Profiles were significantly associated with subsequent adolescents' reports of adjustment such that adolescents of affective-control fathers reported significantly more externalizing behaviors than adolescents of emotionally-involved fathers.

Emotion understanding, theory of mind, and prosocial orientation: Relations over time in early childhood.

Data were collected when children were 42, 54, and 72 months of age (Ns=210, 191, and 172 for T1, T2, and T3, respectively). Children's emotion understanding (EU) and theory of mind (ToM) were examined as predictors of children's prosocial orientation within and across time. EU positively related to children's sympathy across 2.5 years, and T1 EU positively related to parent-reported prosocial orientation concurrently and across 1 year (T2). T2 ToM positively related to parents' reports of sympathy and prosocial orientation concurrently and 18 months later (T3); in contrast, T3 ToM did not relate to sympathy or prosocial orientation. T2 ToM accounted for marginally significant variance (p<0.058) in T3 mother-reported prosocial orientation over and above that accounted for by T2 prosocial orientation. Fostering the development of EU and ToM may contribute to children's prosocial orientation.

True or false: do 5-year-olds understand belief?

In 3 studies (N = 188) we tested the hypothesis that children use a perceptual access approach to reason about mental states before they understand beliefs. The perceptual access hypothesis predicts a U-shaped developmental pattern of performance in true belief tasks, in which 3-year-olds who reason about reality should succeed, 4- to 5-year-olds who use perceptual access reasoning should fail, and older children who use belief reasoning should succeed. The results of Study 1 revealed the predicted pattern in 2 different true belief tasks. The results of Study 2 disconfirmed several alternate explanations based on possible pragmatic and inhibitory demands of the true belief tasks. In Study 3, we compared 2 methods of classifying individuals according to which 1 of the 3 reasoning strategies (reality reasoning, perceptual access reasoning, belief reasoning) they used. The 2 methods gave converging results. Both methods indicated that the majority of children used the same approach across tasks and that it was not until after 6 years of age that most children reasoned about beliefs. We conclude that because most prior studies have failed to detect young children's use of perceptual access reasoning, they have overestimated their understanding of false beliefs. We outline several theoretical implications that follow from the perceptual access hypothesis.

Relations between Mattering to Step- and Non-Residential Fathers and Adolescent Mental Health.

This study examined the relations between perceptions of 133 early adolescents in stepfamilies concerning how much they mattered to their stepfathers and nonresidential biological fathers and adolescents' mental health problems. Mattering to nonresidential biological fathers significantly negatively predicted mother-, teacher-, and youth-reported internalizing problems. Mattering to stepfathers significantly negatively predicted youth-reported internalizing and stepfather- and youth- reported externalizing problems. For teacher-reported externalizing problems, mattering to stepfathers and nonresidential biological fathers significantly interacted. Mattering to either father predicted low externalizing problems; perceptions of mattering to the second father did not predict a further reduction in problems. Results suggest that mattering is an important aspect of father-adolescent relationships, and highlight the importance of considering adolescents' relationships with both nonresidential fathers and stepfathers.

Postdivorce living arrangements, parent conflict, and long-term physical health correlates for children of divorce.

The authors tested a biopsychosocial model in which young adults' long-term relationships with fathers and ongoing distress surrounding their parents' divorces mediated the relationship between disrupted parenting (i.e., exposure to parent conflict before the divorce and up to 5 years after, and amount of time with father postdivorce) and indicators of their physical health. University students whose parents divorced before they were 16 (n = 266) participated. Findings supported the model. The more time children lived with their fathers after divorce, the better their current relationships were with their fathers, independent of parent conflict. The more parent conflict they experienced, the worse their relationships were with their fathers and the more distress they currently felt about their parents' divorce, independent of time with father. Poor father-child relationships and more distress in turn predicted poorer health status. There was no interaction between exposure to parent conflict and time with father; thus, more time with father was beneficial in both high- and low-conflict families, and more exposure to parent conflict was detrimental at both high and low levels of time with father.
