The purposes of this study were to clarify how social problem-solving processes develop and to identify developmentally-sensitive intervention components for children's aggression. Elementary and junior-high school Japanese students (N = 1100) from urban public schools participated in the present investigation. Their alternative thinking skills,…

Major psychological theories of morality and motivation make the assumption that an inverse relationship exists between guilt and satisfaction. To the extent that feelings of guilt are linked to a particular motivational or moral stance, it is assumed that feelings of satisfaction are unlikely also be linked to that stance. Empirical findings in…

California has one of the latest kindergarten entry cutoff dates in the nation, December 2, which effectively allows children as young as four years, nine months to enter kindergarten. Proponents of moving the cutoff date to earlier in the year contend that children who enter kindergarten before age five are not developmentally mature enough yet…

Previous studies have suggested that typically developing 6-month-old infants are able to discriminate between small and large numerosities. However, discrimination between small numerosities in young infants is only possible when variables continuous with number (e.g. area or circumference) are confounded. In contrast, large number discrimination…

Object recognition research is typically conducted using 2D stimuli in lieu of 3D objects. This study investigated the amount and complexity of knowledge gained from 2D stimuli in adult chimpanzees ("Pan troglodytes") and young children (aged 3 and 4 years) using a titrated series of cross-dimensional search tasks. Results indicate that 3-year-old…

The present study examined the developmental origin of "blue lies", a pervasive form of lying in the adult world that is told purportedly to benefit a collective. Seven, 9-, and 11-year-old Chinese children were surreptitiously placed in a real-life situation where they decided whether to lie to conceal their group's cheating behavior. Children…

The McGurk effect paradigm was used to examine the developmental onset of inter-language differences between Japanese and English in auditory-visual speech perception. Participants were asked to identify syllables in audiovisual (with congruent or discrepant auditory and visual components), audio-only, and video-only presentations at various…

Three-, 5-, and 7-year-olds and adults (N = 64) listened to stories depicting 2 protagonists of different ages (infant and child or child and grownup) that encounter an entity that looks like a real (e.g., a snake) or an imaginary (e.g., a ghost) fear-inducing creature. Participants predicted and explained each protagonist's intensity of fear.…

Parental questionnaires are inexpensive alternatives to standardized testing for outcome measurement. The Parent Report of Children's Abilities has previously been revised (PARCA-R) and validated for use with very-preterm infants at 2 years of age. This study revalidated the PARCA-R for assessing cognition in a larger and more inclusive sample of…

The connection between pubertal stage and the development and depressive symptoms among females is investigated. Findings reveal that advancing pubertal stage presents greater risks for the beginning and persistence of depressive symptoms among females. The impacts of social adversity on the persistence of symptoms for female depression.

The revised Temperament and Character Inventory (TCI-R) is the third stage of development of a widely used multiscale personality inventory that began with the Tridimensional Personality Questionnaire (TPQ) and then the Temperament and Character Inventory (TCI). The author describes the third stage of the psychobiological theory of temperament and…

Teleo-functional explanations account for objects in terms of purpose, helping us understand objects such as pencils (for writing) and body parts such as ears (for hearing). Western-educated adults restrict teleo-functional attributions to artifact, biological, and behavioral phenomena, considering such explanations less appropriate for nonliving…

Background: Few family-based healthy lifestyle programs for Latinos have been conducted, especially family programs targeting mother-daughter dyads. Purpose: To assess the acceptability and feasibility of the Behavior Opportunities Uniting Nutrition Counseling and Exercise (BOUNCE) program designed for Latino mother-daughter pairs. Methods: 92…

Gifted kids often share a list of common traits, but ultimately, they are individuals. They have their own strengths, their own weaknesses, and their own needs. One trait that many gifted children "do" share is asynchrony. In other words, gifted children may not follow a typical age appropriate time line. They may be markedly advanced, average, or…

At the initiative of the Government of the People's Republic of China, a letter of intent concerning a joint undertaking for studying children with intellectual disability in China was formulated together with the Swedish Government's Ministry of Social Affairs in the early 1990s. The Swedish Board of Health and Welfare invited Uppsala University…
