The relations among children's theory of mind (ToM), their understanding of the intentionality of teaching, and their own peer teaching strategies were tested. Seventy-five 3-, 4-, and 5-year-olds completed 11 ToM and understanding of teaching tasks. Subsequently, 30 of the children were randomly chosen to teach a peer a board game in which the tea...

Abstract HIV-infected patients frequently experience depression, drug use, and unstable housing but are often unable to access supportive services to manage these challenges. Data on barriers to needed supportive services are critical to improving patient access. Data from the Medical Monitoring Project (MMP), a national supplemental surveillance s...

Latina women represent nearly half of all females diagnosed with AIDS in Los Angeles County, yet little is known about their risk behaviors compared to women of other race/ethnicities. Compared to white and African American women with AIDS, Latinas with AIDS had fewer lifetime male sexual partners (P<.0001); reported fewer sexually transmitted dise...

Latinos are more likely to test late for HIV infection compared to other racial/ethnic groups in the United States. A population-based interview study was used to examine factors associated with late HIV testing for Latinos diagnosed with AIDS in Los Angeles County (LAC) to develop more effective HIV testing outreach strategies. Latinos testing for...

Demographic and behavioral factors associated with methamphetamine use are presented for 455 men who have sex with men (MSM) and 228 non-MSM diagnosed with AIDS in Los Angeles County (LAC) from 2000 to 2004, as there are limited population-based data for these subgroups. Lifetime methamphetamine use was 35% for MSM, 14% for non-MSM, 50% for white M...

Two studies examined the role of intention in preschoolers' understanding of teaching. Three- to 5-year-olds judged stories in which there was an intention to teach or not (teaching vs. imitation) for 4 different learning outcomes (successful, partial, failed, and unknown). They also judged 2 stories with embedded instructional intent (e.g., guided...

This study examined HIV-associated mortality in infants and in women of childbearing age (15-44 years) in the United States from 1990-2001. HIV-associated deaths were identified from national vital records using multiple cause-of-death data. HIV-associated mortality was higher in black and Hispanic women than in white women (rate ratio(black) = 13....

Despite a decreasing incidence of listeriosis in the United States, molecular subtyping has increased the number of recognized outbreaks. In September 2000, the New York City Department of Health identified a cluster of infections caused by Listeria monocytogenes isolates with identical molecular subtypes by pulsed-field gel electrophoresis (PFGE)...

The relation between preschoolers’ concept of teaching and theory of mind was explored to determine if there is a developmental change in understanding how teaching depends on knowledge and belief. The study tested whether 3- to 6-year-olds thought the awareness of a knowledge difference is necessary for teaching. The 3- and 4-year-olds understood...

Summarizes the 9 experiments presented in the Monograph The development of executive function in early childhood (see records 2003-10549-001; 2003-10549-002; 2003-10549-003; 2003-10549-004; 2003-10549-005 and 2003-10549-007). The following topics are discussed: (1) implications for alternative accounts of the development of executive functio...

According to the Cognitive Complexity and Control (CCC) theory, the development of executive function can be understood in terms of age-related increases in the maximum complexity of the rules children can formulate and use when solving problems. This Monograph describes four studies (9 experiments) designed to test hypotheses derived from the CCC...

Belief and desire are commonly assumed to be the core mental states needed to understand others' behavior. Few studies, however, have investigated both. The current studies assessed whether young children's difficulty with false belief can be explained by desire's dominance over belief, as J. A. Fodor's (1992) nativist theory and the theory theory...

In June 2001, the Los Angeles County Department of Health Services/Public Health conducted a cohort study of an outbreak of acute febrile gastroenteritis among 16 of 44 healthy attendees of a catered party. The median age of the attendees who became ill was 15.5 years. Symptoms included body aches (in 88% of attendees), fever (81%), headache (81%),...

Cognitive complexity and control (CCC) theory, which is a theory of executive function and its development, provides a metric for comparing task demands across domains. This metric allowed us to examine the relation between theory of mind (ToM) and one aspect of executive function, rule use, in 22 individuals with autism-spectrum disorders, includi...

Limitations of Dienes & Perner's (D&P's) theory are traced to the assumption that the higher-order thought (HOT) theory of consciousness is true. D&P claim that 18-month-old children are capable of explicitly representing factuality, from which it follows (on D&P's theory) that they are capable of explicitly representing content, attitude, and...

Relational complexity provides a metric for measuring task demands, and in this respect has much in common with the cognitive complexity and control theory. However, relational complexity does not account for the relative difficulty of different relational types, and appears to underestimate the importance of changes in children's ability to a...

Executive function (EF) accounts have now been offered for several disorders with childhood onset (e.g., attention-deficit/hyperactivity disorder, autism, early-treated phenylketonuria), and EF has been linked to the development of numerous abilities (e.g., attention, rule use, theory of mind). However, efforts to explain behavior in terms of EF ha...

The relationship between Theory of Mind (ToM) and rule use was explored in adults with Down's Syndrome (DS) and in non-handicapped pre-schoolers. Twelve low-functioning individuals with DS (mean mental age = 5.1 years, mean chronological age = 22.7) performed worse than 12 MA-matched non-handicapped children (mean MA = 5.1 years) on several standar...

Triploid Sydney rock oysters, Saccostrea commercialis (produced using cytochalasin B to treat newly fertilised eggs), were sampled from 22–34 months of age to encompass a full reproductive season. A comparative assessment of the extent of gametogenesis was made for both diploid and triploid Sydney rock oysters. It was necessary to develop separate...

Four experiments examined children's ability to use their knowledge to guide their behavior in a dimensional change (color-shape) card sort. In Experiment 1, 3- and 4-year-olds were told to sort cards first by one dimension (e.g., color: “Yellow ones go here; green ones go there”) and then by the other. The majority of 3-year-olds continued to use...

The hypothesis is tested that during the preschool period a particular form of reasoning is applied to theory of mind and a set of problems that do not require the understanding of mental states. Three experiments each provided a different piece of support for this hypothesis. Experiment 1 found similar age-related changes between three standard th...
