How much can children see and report about their experience of a brief glance at a natural scene?

Recent studies on brief scene perception have revealed that adults discriminate between what they see and do not see in a photograph with varying degrees of confidence. In this study, we attempt to extend previous studies by asking if these perceptual/cognitive abilities are already established in preschool and school-aged children. In Experiment 1 ( = 122) and 2 ( = 205, registered report), using an online experiment, we briefly presented a natural scene (267 ms in Experiment 1 and 133 ms in Experiment 2) to participants and, subsequently, asked them if a small patch was included in the original scene.

Self-directed music play to improve executive function in young children using NIRS.

Play is fundamental to child development, with evidence highlighting its crucial role in enhancing executive function (EF). However, the neural mechanisms underlying play-based cognitive improvements remain poorly understood. Here, we examine how music play influences behavioral performance and prefrontal cortex (PFC) activity in preschoolers using functional near-infrared spectroscopy (fNIRS).

Hostile Cognitions and Aggressive Responses Toward Excluders in Young Children.

Social exclusion heightens hostile cognition and aggressive responses toward excluders. However, its direct causal effects and relationship with self-construal are unclear in early childhood. This study experimentally investigated the effects of social exclusion on later hostile cognition and aggressive responses toward excluders (vs.

Comparing color qualia structures through a similarity task in young children versus adults.

Examination of the subjective qualitative aspects of an experience, or "qualia" in short, is a fundamental and core aspect of consciousness research. How can we characterize the particular quality of redness, i.e.

Hostile cognitions and emotions following social exclusion in Japanese adults and young children.

Social exclusion heightens negative emotions and hostile cognition toward others; however, its effects on non-Western adults and children remain unclear. These studies examined the effects on Japanese adults (N = 68; 34 female; M = 21.87 years) and 4- to 6-year-old children (N = 147; 78 female).

Psychology needs more diversity at the level of Editor-in-Chief.

There are racial, gender, and geographical disparities for editors-in-chief in psychology. This is a problem, and many counter arguments are not persuasive. It is time for the field – and in the power of individuals - to implement suitable measures to make change happen.

Balancing exploration and exploitation? The impact of cost and inhibitory control on information gathering in early childhood.

The information-seeking behaviour of adults focuses on optimizing the gathering and utilizing information to minimize search costs. In contrast, children tend to engage in information search during decision-making with less consideration for costs. This difference in behaviour is believed to be linked to the development of executive functions.

Development of emergent processes and threshold of consciousness with levels of processing.

Introduction: The transition of experience from unconscious to conscious, the emergent process, is a crucial topic in consciousness studies. Three frameworks exist to explain the process: (1) consciousness arises in an all-or-none manner; (2) consciousness arises gradually; (3) consciousness arises either all at once or gradually, depending on the level of stimulus processing (low- vs. high-level).

Gender stereotypes regarding power and niceness in Japanese children.

Belief in gendered social power imbalance (i.e. males are more powerful than females) leads to undesirable gender disparities, but little is known about the developmental origins of this belief, especially in Eastern cultures.

Large-scale data decipher children's scale errors: A meta-analytic approach using the zero-inflated Poisson models.

Scale errors are intriguing phenomena in which a child tries to perform an object-specific action on a tiny object. Several viewpoints explaining the developmental mechanisms underlying scale errors exist; however, there is no unified account of how different factors interact and affect scale errors, and the statistical approaches used in the previous research do not adequately capture the structure of the data. By conducting a secondary analysis of aggregated datasets across nine different studies (n = 528) and using more appropriate statistical methods, this study provides a more accurate description of the development of scale errors.

Young children's subjective and objective thresholds and emergent processes of visual consciousness using a backward masking task.

Visual consciousness studies in humans have primarily focused on adults. However, whether young children's visual consciousness is similar to or different from that of adults remains unknown. This study examined young children's and adults' subjective awareness and objective discrimination for thresholds and emergent processes of visual consciousness in two experiments.

The Relationship Between Hostile Intent Attribution and Aggression in Japanese Children.

Previous studies showed that hostile intent attribution (HIA) was significantly correlated with and contributed to the development of aggression in children. Studies that directly examined the factors that explained the relationship between HIA and aggression are lacking. Hence, this study investigated (a) the correlation between HIA and aggression and (b) the variables (hyperactivity, prosociality, and collaborative problem-solving) that mediated the relationship between HIA and aggression in Japanese children aged 4-9 years.

The effect of metacognitive executive function training on children's executive function, proactive control, and academic skills.

The current study investigated the effects of metacognitive and executive function (EF) training on childhood EF (inhibition, working memory [WM], cognitive flexibility, and proactive/reactive control) and academic skills (reading, reasoning, and math) among children from disadvantaged backgrounds. Children ( = 134, = 8.70 years) were assigned randomly to the three training groups: (a) metacognitive training of basic EF processes (meta-EF), (b) training of basic EF processes (basic-EF), and (c) active controls (active control).

Psychophysiological responses of shame in young children: A thermal imaging study.

Shame can be defined as the emotional response to one's violations of rules being exposed to others. However, it is difficult to objectively measure this concept. This study examined the psychophysiological indicators of shame in young children using behavioral methods and thermography, which measures facial temperatures that reflect blood flow changes related to emotions.

Children attribute higher social status to people who have extraordinary capabilities.

Throughout history, individuals believed to have extraordinary capabilities were generally highly ranked in their communities; this suggests a universal "extraordinary-dominant expectation" in human minds, which may play a key role in religious thought, even in modern societies. This study shows that 5-6-year-old children, who begin to understand real-world causalities regarding how the body and mind of human beings work, predict that individuals who exhibit extraordinary capabilities have higher social status in interactions with individuals who exhibit ordinary capabilities. In Experiment 1, we showed children two individuals achieving goals using either humanly possible or impossible methods, the latter involving simple forms of violation of intuitive psychology (knowing without seeing), physics (flying), or biology (fire breathing).

Viewing and playing fantastical events does not affect children's cognitive flexibility and prefrontal activation.

Media exposure, such as viewing fantastical content, can have negative, immediate, and long-term effects on children's executive function. A recent study showed that watching fantastical content on a tablet can impair children's inhibitory control and prefrontal activation during the performance of a task. However, the same effect was not observed when children played fantastical games on a tablet.

Exploring role of sleep aids in sleep problems in preschool children.

It is well known that children use sleep aids, such as blankets or soft toys, at bedtime. However, there is a lack of understanding regarding the factors associated with their use and role in addressing sleep problems. This study investigated 96 Japanese children aged 40 to 47 months to examine these associations.

Visual memory of a co-actor's target during joint search.

Studies on joint action show that when two actors turn-takingly attend to each other's target that appears one at a time, a partner's target is accumulated in memory. However, in the real world, actors may not be certain that they attend to the same object because multiple objects often appear simultaneously. In this study, we asked participant pairs to search for different targets in parallel from multiple objects and investigated the memory of a partner's target.

Evaluating the Distinction between Cool and Hot Executive Function during Childhood.

This article assesses the cool-hot executive function (EF) framework during childhood. First, conceptual analyses suggest that cool EF (cEF) is generally distinguished from hot EF (hEF). Second, both EFs can be loaded into different factors using confirmatory factor analyses.

Parental responsiveness and children's trait epistemic curiosity.

Curiosity, the desire to learn new information, has a powerful effect on children's learning. Parental interactions facilitate curiosity-driven behaviors in young children, such as self-exploration and question-asking, at a certain time. Furthermore, parenting quality predicts better academic outcomes.

The contextual cueing effect disappears during joint search in preschool children.

During preschool years, children's interacting with others increases. One of the involved developmental skills is task co-representation, through which children aged 5 years and older represent a partner's task in a similar way to their own task. In adults, task co-representation makes participants attend to and form memories of objects relevant to both their own task and their partner's task; however, it is unclear whether children can also form such memories.

Gender stereotypes about intellectual ability in Japanese children.

Japan has a large gender gap; thus, this study examined whether Japanese 4- to 7-year-old children exhibit a "brilliance = males" stereotype and whether parental attitudes toward gender roles were related to children's stereotypes. We also explored whether the children exhibited such stereotypes in response to various stimuli. We showed children photos (Study 1) and stick figures (Study 2) of men, women, boys, and girls, asking them to attribute traits (smart or nice) to each.

Visual image of God/gods during early childhood.

This study examined whether Japanese children have a different visual image of God/gods than children from Western countries, who have an image of an old White man. Study 1 comprised 183, 4-7-year-old Japanese children (93 girls), who had to choose a face that looked like God/gods from among pictures of faces that differed on age (e.g.

Object labeling activates young children's scale errors at an early stage of verb vocabulary growth.

Scale errors are intriguing developmental phenomena in which young children attempt to perform impossible object-specific actions toward miniature-sized objects. Of several related cognitive abilities, lexical development during toddlerhood enhances scale error production by making objects' semantic representations dominant over perceptual information. To directly address the effect of activated semantic representations on scale errors, we examined whether and when object labeling affected scale errors.

When "shoe" becomes free from "putting on": The link between early meanings of object words and object-specific actions.

Nouns referring to objects dominate children's early vocabulary over verbs referring to actions. However, some scholars have argued that early object-word meanings cannot be easily classified into specific object categories; rather, they have much undifferentiated meanings in which both objects and their specific actions are intertwined. We experimentally investigated this view using a two-alternative forced-choice task involving toddlers aged 18-23 months (n = 69).
