What motivates early lies? Deception in 2½- to 5-year-olds

What motivates young children to produce early lies? A total of 217 2½- to 5-year-old children (Mage = 44.5 months, SD = 8.45; 54% girls; 61.7% White) from the southeastern United States were tested using a modified third-party transgression paradigm to examine the motivation behind their deception. Children were assigned to one of three conditions-baseline, self-motivated, or other-motivated condition-and their propensity to lie was captured through both verbal and nonverbal measures. Results show that children's early lies are primarily driven by a self-serving motivation. However, the motivation to lie diversifies by 4 years of age, when children begin to lie for both self-serving and other-serving motivations.

Testing Causal Effects of Empathy on Children's Prosociality in Politeness Dilemmas - An Intervention Study

Empathy is commonly considered a driver of prosociality in child ontogeny, but causal assumptions regarding this effect mostly rely on correlational research designs. Here, 96 urban German children (5-8 years; 48 girls; predominantly White; from mid-to-high socioeconomic backgrounds) participated in an empathy intervention or a control condition before prosocial behaviors (polite lie-telling: rating the drawing as good; prosocial encouragement: utterances interpreted as cheering up the artist) were assessed in an art-rating task. Contrasting children's empathy at baseline with their empathy after the intervention indicated promoted empathy compared to the control group. Despite the intervention's effect on children's empathy, there were no simultaneous changes in prosocial behaviors. At the same time, children's empathy at baseline was associated with their prosocial encouragement. These results indicate conceptual associations between children's empathy and prosociality. However, they do not support strict causal claims regarding this association in middle childhood. Further applications of the novel short-time intervention to address causal effects of empathy on prosociality and other developmental outcomes are discussed.

Exploring the development of high-level contributions to body representation using the rubber hand illusion and the monkey hand illusion

During development our body undergoes significant changes, yet we are able to maintain a coherent experience of our body and sense of self. Bodily experience is thought to comprise integration of multisensory signals (vision, touch, and proprioception) constrained by top-down knowledge of body appearance. Evidence from developmental studies suggests that low-level multisensory integration develops throughout childhood, reaching adult levels by 10 years of age. However, how high-level cognitive knowledge changes during childhood to constrain our multisensory body experience is unknown. This study describes four experiments examining high-level contributions to the bodily experience in children compared with adults using the rubber hand illusion and a monkey hand illusion. We found that children (5-17 years of age) exhibited more flexible body representations, showing stronger illusions for small and fantastical (monkey) fake hands compared with adults. Conversely, using a task indirectly capturing changes in hand size, we found that children and adults demonstrated statistically equivalent increases and decreases in hand size following illusions over large and small hands, respectively. Interestingly, at baseline children showed a bias in reporting larger hand size judgments that decreased with age. Finally, we did not find a relationship between individual differences in fantasy proneness and illusion strength for a fantastical (monkey) hand for children or adults, suggesting that developmental changes of top-down constraints are not purely driven by more diffuse boundaries between imagination and reality. These data suggest that high-level constraints acting on our multisensory body experience change during development, allowing children a more flexible bodily experience compared with adults.
