Research on goal-predictive gaze shifts in infancy so far has mostly focused on the effect of infants’ experience with observed actions or the effect of agency cues that the observed agent displays. However, the perspective from which an action is presented to the infants (egocentric vs. allocentric) has received only little attention from researchers despite the fact that the natural observation of own actions is always linked to an egocentric perspective, whereas the observation of others’ actions is often linked to an allocentric perspective. The current study investigated the timing of 6-, 9-, and 12-month-olds’ goal-predictive gaze behavior, as well as that of adults, during the observation of simple human grasping actions that were presented from either an egocentric or allocentric perspective (within-participants design). The results showed that at 6 and 9 months of age, the infants predicted the action goal only when observing the action from the egocentric perspective. The 12-month-olds and adults, in contrast, predicted the action in both perspectives. The results therefore are in line with accounts proposing an advantage of egocentric versus allocentric processing of social stimuli, at least early in development. This study is among the first to show this egocentric bias already during the first year of life.

Motivated by theories of music-to-language transfer, we investigated whether and how musicianship benefits phonological and lexical prosodic awareness in first language (L1) Cantonese and second language (L2) English. We assessed 86 Cantonese–English bilingual children on rhythmic sensitivity, pitch sensitivity, nonverbal intelligence, inhibitory control, working memory, Cantonese phonological awareness, Cantonese tone awareness, English phonological awareness, and English stress awareness. Based on their prior music learning experience, we classified the children as musicians and non-musicians. The musicians performed better than the non-musicians on Cantonese phonological awareness, Cantonese tone awareness, and English phonological awareness. In addition, the musicians had superior pitch sensitivity, nonverbal intelligence, inhibitory control, and working memory than the non-musicians. For Cantonese and English phonological awareness, neither cognitive abilities nor pitch and rhythmic sensitivities turned out to be a unique predictor. However, working memory uniquely predicted Cantonese tone awareness, with age, rhythmic sensitivity, and pitch sensitivity controlled. From a theoretical perspective, our findings on Cantonese tone awareness favors the cognitive perspective of music-to-language transfer, in which working memory enhancement could explain the musicians’ superior performance in Cantonese tone awareness. However, our findings on phonological awareness do not favor the cognitive perspective, nor do they favor the perceptual perspective, in which enhanced rhythmic and pitch sensitivities could explain musicians’ advantage.

Expectations about how others’ actions unfold in the future are crucial for our everyday social interactions. The current study examined the development of the use of kinematic cues for action anticipation and prediction in 3-year-olds, 4-year-olds, 10-year-olds, and adults in two experiments. Participants observed a hand repeatedly reaching for either a close or far object. The motor kinematics of the hand varied depending on whether the hand reached for the close or far object. We assessed whether participants would use kinematic cues to visually anticipate (Experiment 1; N=98) and verbally predict (Experiment 2; N=80) which object the hand was going to grasp. We found that only adults, but not 3- to 10-year-olds, based their visual anticipations on kinematic cues (Experiment 1). This speaks against claims that action anticipations are based on simulating others’ motor processes and instead provides evidence that anticipations are based on perceptual mechanisms. Interestingly, 10-year-olds used kinematic cues to correctly verbally predict the target object, and 4-year-olds learned to do so over the trials (Experiment 2). Thus, kinematic cues are used earlier in life for explicit action predictions than for visual action anticipations. This adds to a recent debate on whether or not an implicit understanding of others’ actions precedes their ability to verbally reason about the same actions.

What behaviors make people happy? In the current studies, we investigated 4- to 7-year-old children’s (N = 148) emotion attributions for people who follow or violate a conventional norm when doing so aligns or conflicts with other psychological motivations. In Study 1, we tested whether children believe people are happier when they desire (vs. do not desire) adhering to (vs. violating) a norm. In Study 2, we tested whether children believe people are happier when freely choosing (vs. being told) to adhere to (vs. violate) a norm. In both studies, children predicted the highest happiness levels for people who followed norms even when doing so conflicted with other psychological motivators (e.g., wanting or freely choosing to do something). Children also explained their emotion attributions by making reference to norms more often than to desires or personal choices. Results are discussed in terms of implications for children’s own norm adherence and early socialization practices in Western cultures.

Individuals revise their beliefs based on the evidential strength of others’ claims. Unlike English, in languages such as Turkish evidential marking is obligatory; speakers must express whether their claims are based on direct observation or not. We investigated whether Turkish- and English-speaking 3- and 5-year-olds (N = 146; 72 girls; based in Turkey and Canada) differed in their belief revision after hearing claims based on direct observation, indirect observation, or inference. We found the same pattern in both linguistic groups; the 3-year-olds revised their beliefs more often when they heard claims based on direct observation and inference than on indirect observation, whereas the 5-year-olds showed no difference across different claims. By age 3, Turkish- and English-speaking children are sensitive to the strength of claims when revising their beliefs.

It has been established that young children who use their fingers to solve arithmetic problems outperform those who do not. However, it remains unclear whether finger counting itself enhances arithmetic performance or if children with already advanced numerical abilities are more inclined to use this strategy. In the current study, to shed light on this matter, we observed the behavior of 189 4- and 5-year-old children in an addition task and a task assessing their knowledge of the three “how-to-count” principles (i.e., stable order, one-to-one correspondence, and cardinality principles). Of these children, 169 were reassessed 1 year later (the second testing point). At the first testing point, our results revealed that finger users better know the counting principles than non-finger users. Nevertheless, some children use their fingers without knowing the principles, but in this case they present low performance in the addition task. Moreover, we found that knowing the counting principles does not naturally prompt finger use. Finally, we did not find evidence supporting the idea that finger use has a specific role in the development of counting principles, which questions the idea that finger counting has a functional role in the construction of the number concept. All in all, our results tend to show that children need to know the counting principles to be efficient finger users. Therefore, finger counting seems to be a useful tool when used by children who already possess advanced numerical knowledge.

Collaboration requires individuals to find partners who are adept at problem-solving and act fairly when sharing the spoils of joint labor. Given that individuals might vary along both dimensions, it can create a dilemma with the challenging decision of whether to prioritize a potential partner’s capacity to perform a task or the partner’s level of fairness in sharing obtained resources. Here we tested whether young children can solve this dilemma when two potential partners have opposing qualities: One partner is high in the capacity to solve a problem but less likely to share fairly, whereas the other partner is lower in capacity but fair. In two studies with a total of N = 188 children aged 4 to 6 years, we found that children adjust their decisions based on the social context and the perceived difficulty of the collaborative task: Children show an overall preference for fair partners when collaborating in an easy task, but they choose partners high in problem-solving capacity and low in fairness when collaborating in a more difficult task. These results show that already young children can evaluate others along two dimensions and make trade-offs between capacity and fairness when deciding what is more relevant for a given situation.

Sensitivity to linguistic cues, in theory, can change the interpretation of social and game theoretical behavior. We tested this in a pair of experiments with children aged 4 and 5 years. Children were asked to give some, keep some, or put some stickers for themselves or for another player (a puppet) after collaborative activities. We found that the direction of the verb did influence how selfish the younger children were. We also had children tidy up the toys after each activity to determine their interpretation of some. Children could derive the pragmatic scalar implicature linked to some (i.e., interpreting it as meaning not all), and they did so particularly when it affected them personally. These findings have important implications for the stability of other-regarding preferences and the importance of instructions in games.

Learning in the everyday environment often requires the flexible integration of relevant multisensory information. Previous research has demonstrated preverbal infants’ capacity to extract an abstract rule from audiovisual temporal sequences matched in temporal synchrony. Interestingly, this capacity was recently reported to be modulated by crossmodal correspondence beyond spatiotemporal matching (e.g., consistent facial emotional expressions or articulatory mouth movements matched with sound). To investigate whether such modulatory influence applies to non-social and non-communicative stimuli, we conducted a critical test using audiovisual stimuli free of social information: visually upward (and downward) moving objects paired with a congruent tone of ascending or incongruent (descending) pitch. East Asian infants (8–10 months old) from a metropolitan area in Asia demonstrated successful abstract rule learning in the congruent audiovisual condition and demonstrated weaker learning in the incongruent condition. This implies that preverbal infants use crossmodal dynamic pitch–height correspondence to integrate multisensory information before rule extraction. This result confirms that preverbal infants are ready to use non-social non-communicative information in serving cognitive functions such as rule extraction in a multisensory context.

Research on mathematical cognition, learning, and instruction (MCLI) often takes cognition as its point of departure and considers instruction at a later point in the research cycle. In this article, we call for psychologists who study MCLI to reflect on the “status quo” of their research practices and to consider making instruction an earlier and more central aspect of their work. We encourage scholars of MCLI (a) to consider the needs of educators and schools when selecting research questions and developing interventions; (b) to compose research teams that are diverse in the personal, disciplinary, and occupational backgrounds of team members; (c) to make efforts to broaden participation in research and to conduct research in authentic settings; and (d) to communicate research in ways that are accessible to practitioners and to the general public. We argue that a more central consideration of instruction will lead to shifts that make research on MCLI more theoretically valuable, more actionable for educators, and more relevant to pressing societal challenges.
