The number line estimation task is frequently used to measure children's numerical magnitude understanding. It is unclear whether the resulting straight, horizontal, left-to-right-oriented estimate patterns indicate task constraints or children's intuitive number--space mapping. Three- to six-year-old children (N = 72, M[subscript age] = 4.89, 56%…

The public debate on the use of the German nonbinary gender asterisk ("Lehrer*in" 'teacher') is emotionally charged. While it has been adopted by political and educational institutions, opponents argue that it is inappropriate for making persons identifying themselves beyond the male-female-dichotomy more visible. We investigated this…

Previous research shows that children evaluate the competence of others based on how effectively someone accomplished a goal, that is, based on the observed outcome of an action (e.g., number of attempts needed). Here, we investigate whether 5- to 10-year-old children and adults infer competence from how efficiently someone solves a task by…

Several studies have demonstrated that individual differences in processing speed fully mediate the association between age and intelligence, whereas the association between processing speed and intelligence cannot be explained by age differences. Because measures of processing speed reflect a plethora of cognitive and motivational processes, it…

The current study aimed to investigate the cultural differences in the developmental origins of children's intent-based moral judgment and moral behavior in the context of indirect reciprocity. To this end, we compared how German and Chinese children interpret and react to antisocial and prosocial interactions between puppets. An actor puppet…

This research examined an important applied question: whether viewing ambient green (relative to red) on the wall of a workspace would facilitate creativity. A methodologically sound experiment revealed no influence of green on creativity. Care must be taken when interpreting a null result, but these data do not provide support for the presence of…

This study examined whether age differences in risky decision making are dependent on known probability and value of outcomes (i.e., the expected value [EV]), the valence of anticipated outcomes (gains or losses), and individual differences in working memory and impulsivity. We used a task that varied risk independently from EV so that taking…

The goal of the present study is to explore bilinguals' intercultural style of requesting in a workplace setting and thereby contribute to the understanding of bilingual pragmatic competence. The relatively unexplored intercultural style hypothesis suggests that bilinguals show a unique pragmatic pattern related to but distinct from the contact…

We investigated the ability to detect a face among other visual objects in a complex visual array in 3-, 4-, and 5-year-old children, as well as in adults. To this end, we used a visual search paradigm implemented on a touch-tablet device. Subjects (N = 100) saw up to eighty 3 × 3 visual search arrays and had to find and tap upon a target--a face…

The acquisition of voice in Greek remains understudied, especially in heritage populations. Voice in Greek poses a challenging acquisition task for children due to its syncretism, marking various verb classes as well as passives. The present study explores the acquisition of anticausatives, reflexives, and passives in 6-to-8-year-old monolingual…

Performance in elementary cognitive tasks is moderately correlated with fluid intelligence and working memory capacity. These correlations are higher for more complex tasks, presumably due to increased demands on working memory capacity. In accordance with the binding hypothesis, which states that working memory capacity reflects the limit of a…

First-order theory of mind (ToM) development has shown to conform to a Guttman scale, with desire reasoning developing before belief reasoning. There have been attempts to test for internal consistency and scalability in advanced ToM, but not over a broad age range and only with a limited set of tasks. This 2-year longitudinal study (N = 155;…

It has been argued that people construct situation models during text reception and that these are analogous, multimodal representations of text grounded in perception and action. On the one hand, abundant evidence has been generated that recipients perceptually simulate features of the situation described in the text. On the other hand, findings…

This study examined preschoolers' social inclusion--the active involvement of new partners into social interactions--in different intergroup contexts. Using an interactive paradigm, 3- to 5-year-old German children played a ball-tossing game with 2 puppets in which 1 puppet initiated the game with the child and another approached the game. In…

Previous work suggests that adolescents are still refining acoustic-phonetic cue use in clear-speech perception. This study shows adolescents' immature perception of reduced speech, in which speech sounds are naturally deleted and merged within and across words. German adults and 16-year-olds listened to either German reduced or unreduced (few or…
