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.

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.

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.

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;  = 12.

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.

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.

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.

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.

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.

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.

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 ( 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 , , and 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.

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.

Review on Haploidentical Hematopoietic Cell Transplantation in Patients with Hematologic Malignancies.

Allogenic hematopoietic cell transplantation (HSCT) is typically the preferred curative therapy for adult patients with acute myeloid leukemia, but its use has been reduced as a consequence of limited donor availability in the form of either matched-related donors (MRD) or matched-unrelated donors (MUD). Alternative options such as unrelated umbilical cord blood (UCB) transplantation and haploidentical HSCT have been increasingly studied in the past few decades to overcome these obstacles. A human leukocyte antigen- (HLA-) haploidentical donor is a recipient's relative who shares an exact haplotype with the recipient but is mismatched for HLA genes on the unshared haplotype.

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 ( = 12.5, 52.

Attributions of Fathering Behaviors Among Adolescents: The Role of Gender, Ethnicity, Family Structure, and Depressive Symptoms.

Little attention has been paid to how early adolescents make attributions for their fathers' behavior. Guided by symbolic interaction theory, we examined how adolescent gender, ethnicity, family structure, and depressive symptoms explained attributions for residential father behavior. 382 adolescents, grouped by ethnicity (European American, Mexican American) and family structure (intact, stepfamilies), reported attributions for their fathers' positive and negative behaviors.

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.

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 group mentioned emotional quality and involvement; an group mentioned emotional quality, involvement, discipline and role modeling; and an group mentioned emotional quality and role modeling.

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.

Fathering and Adolescent Adjustment: Variations by Family Structure and Ethnic Background.

The current study investigated how fathering behaviors (acceptance, rejection, monitoring, consistent discipline, and involvement) are related to preadolescent adjustment in Mexican American and European American stepfamilies and intact families. Cross-sectional data from 393 7 graders, their schoolteachers, and parents were used to examine links between different dimensions of fathering and adolescent outcomes. Following an ecological multivariate model, family SES, marital satisfaction, and mothers' parenting were included as controls.

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.

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.

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.

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.

Reality check: using newspapers, police reports, and court records to assess defensive gun use.

Objective: To identify legitimate defensive gun uses (DGUs), and provide a reality check on previous estimates of the rate of DGUs by using a novel approach based on newspaper reports and police and court records. Previous estimates have relied on self report, differ by a factor of 10 or more, and are viewed as highly controversial.
