Evaluating and communicating about the healthiness of foods: Predictors of parents' judgments and parent-child conversations.

Parents are typically in charge of purchasing the food that their children eat, but little is known about how parents decide if particular foods are healthy for their children and how their beliefs about nutrition influence their children's beliefs. In two studies, we investigated how parents of children ages 4 to 12 (N = 826) make decisions about the healthiness of foods, when presented with different representations of the same nutritional information. Providing parents with nutritional information did not influence their ratings of how healthy food items are, compared to when they are shown only pictures of the foods. Parents reported talking with their children about nutrition, believed they are the best source of information for children about nutrition, and believed their nutrition beliefs influence their child's beliefs. Our findings highlight the role of prior knowledge in food cognition and how beliefs about foods are transmitted from parents to children.

Embracing Death: Mexican Parent and Child Perspectives on Death.

A mixed-method approach was used to explore parent and child perspectives on death in Mexico. Parents' and children's death-related experiences and understanding of death were examined. While all children in this sample displayed a biological understanding of death, older children were less likely to endorse that all living things die. Children also displayed coexistence of beliefs related to death that can be attributed to both their biological and spiritual understanding of death. We also found that older children were more likely to report that a child should feel sad following the death of a loved one. These findings highlight how cultural practices shape the development of cognitive and affective processes related to death.

Do you remember being told what happened to grandma? The role of early socialization on later coping with death.

Using a mixed-methods approach, we examined how participants' memories of socialization regarding death might influence their self-reported coping with losses in childhood and adulthood. We recruited 318 adults to complete an online survey. Path analyses indicated that participants who remembered their parents shielding them less from issues related to death reported better coping as children and adults. Qualitative responses suggested participants wanted to receive more information about death from their parents as they went through the grieving process. We highlight the potential benefits of socializing children about death, and how it may aid in their coping with death-related events.

Drawing across media: A cross-sectional experiment on preschoolers' drawings produced using traditional versus electronic mediums.

Young children's growing access to touchscreen technology represents one of many contextual factors that may influence development. The focus of the current study was the impact of traditional versus electronic drawing materials on the quality of children's drawings during the preschool years. Young children (2-5 years, N = 73) and a comparison group of adults (N = 24) copied shapes using three mediums: marker on paper, stylus on touchscreen tablet, finger on touchscreen tablet. Drawings were later deemed codable or uncodable (e.g., scribbles), and codable drawings were then scored for subjective quality on a 4-point scale. Girls and older children (vs. boys and younger children) produced more codable drawings; however, this gap closed when children drew with their finger on a tablet. Medium also affected the quality of adults' drawings, favoring marker on paper. Thus, drawing on a tablet helped younger children produce drawings but resulted in lower quality drawings among adults. These findings underscore the importance of considering environmental constraints on drawing production. Moreover, since clinical assessments often include measures of drawing quality, and sometimes use tablet computers for drawing, these findings have practical implications for education and clinical practice.

Action Errors: A Window Into the Early Development of Perception-Action System.

In this chapter, we explore an interesting class of behaviors, referred to as action errors, which, we argue, provide a window in to the early development of the perception-action system. As we examine these behaviors, we discuss how acquisition of motor and cognitive skills interact at particular periods of development to make children more likely to perform action errors. However, we also provide evidence that even adults perform action errors under certain task demands. We argue that it is fruitful to examine the developing perception-action system in terms of the dynamic interplay of constraints within the environment, the individual child, and the task that they are attempting to complete. This interaction of constraints is dynamic and multiply determined, which is why action errors do not occur whenever a child sees a photograph of an object, views a tiny chair, or interacts with grandparents over interactive media. We argue, however, that not all constraints are weighted equally in the emergence of a specific behavior. Rather, the child's goal or intention plays a key role in organizing factors that lead to a specific behavior.

COMMENTARY: WHAT HEALS AND WHY? CHILDREN'S UNDERSTANDING OF MEDICAL TREATMENTS.

Lockhart and Keil have written an interesting monograph focusing on the development of reasoning about medicine, a relatively underexplored area of research with potentially broad implications with respect to the design of more-effective medical interventions. In a set of 15 studies with well over 2,200 participants, they examine how children and adults combine aspects of biological and psychological reasoning to create working models of medicine. Lockhart and Keil explore developmental changes in reasoning about illness and its treatment using medicines in terms of dualism (e.g., psychological vs. physical), spatial proximity, differential timing of effects, potential side effects, and treatment tradeoffs. This commentary highlights the novel contributions of this monograph, examines issues that need additional considerations, and makes suggestions for future research.

Knowing How to Fold 'em: Paper Folding across Early Childhood.

Folding paper is a seemingly simple act that requires planning, bimanual coordination, and manual strength and control to produce specific forces. Although paper folding has been used as an assessment tool and as a way to promote spatial skills, this study represents the first attempt to document when paper folding emerges across early childhood. Seventy-seven children (ages 18 months to 7 years) and an adult reference group (24 college-aged adults) completed three pre-specified folds on a single piece of paper. Dependent variables included whether children attempted each fold and, if so, the accuracy of each fold. Grip strength, pinch strength, and developmental level were examined as potential correlates of paper folding. The results demonstrated that paper folding emerges as early as 27 months of age but becomes more accurate with age. At least 50% of children between 4 and 5 1/2 years of age completed folds. Additionally, children with more age-appropriate problem-solving skills attempted more folds, independent of age. These findings provide a descriptive framework for the ages at which paper folding emerges and suggest that paper-folding interventions could be implemented at even earlier ages than what previously has been examined.

Spatial factors influence arithmetic performance: the case of the minus sign.

Spatial features of mathematical equations may influence how people solve and interpret those equations. This study examined whether manipulations of spatial features affected how participants solved and interpreted equations involving the minus sign. Undergraduate participants (N = 91) solved multioperation arithmetic equations involving addition, subtraction, and multiplication (e.g., 25 - 3 + 2 × 5 = __). We varied the spacing of the final three operands and the position of the first operator relative to the adjacent operands. Participants also generated a story problem to correspond with a given equation. We evaluated the procedures that participants used in solving the equations by analysing both their solutions and their written work. Both close spacing of the final three operands and position of the first operation sign influenced the procedures that participants used. Both of the spatial manipulations also influenced participants' interpretations of the conceptual structure of the equations, as revealed in the story problems that they generated. These results have implications for understanding how people process mathematical symbols and for mathematics education.
