The system of second person singular forms of address (2PS) in Medellín, Colombia is tripartite consisting of "tú, vos," and "usted," while also including the existence of a dual "usted." The current study compares usage of the intimate "usted" versus the distant "usted" with data from an oral…

The widespread adoption of mobile technologies has exacerbated their utilization in educational environments. Multitasking in the classroom is a common practice and deserves further investigation to understand its antecedents. Yet, rare studies have addressed this issue based on the theory of planned behavior framework. To this end, the current…

Prospective memory (PM) is vital for children to live independently. Theoretical and empirical evidence has shown that executive function (EF) plays an important role in children's PM. However, there is no EF training for the PM of school-age children. Therefore, a 4-week EF training programme was conducted in this study to investigate the…

Research has established that reading and writing skills are closely linked for most individuals, which can be explained by the shared knowledge and functional relations theoretical perspectives. The current study used quantile regression to explore differences between and within Grades 3-5 in the United States in the associations between a…

This study delves into the syntactic parsing abilities of children and infants exposed to Catalan as their first language. Focusing first on ages 3 to 6, we conducted two sentence-picture matching tasks. In experiment 1, 3 to 4-year-old children failed in identifying singular third-person subjects within null-subject sentences, although they…

The ability to shield against distraction while focusing on a task requires the operation of executive functions and is essential for successful learning. We investigated the short-term dynamics of distraction control in a data set of 269 children aged 4-10 years and 51 adults pooled from three studies using multilevel models. Participants…

We tested 6- and 8-month-old White and non-White infants (N = 53 total, 28 girls) from Northern California in a visual search task to determine whether a unique item in an otherwise homogeneous display (a singleton) attracts attention because it is a unique singleton and "pops out" in a categorical manner, or whether attention instead…

This study investigated the development of rapid visual object categorization. N = 20 adults (Experiment 1), N = 21 five to six-year-old children (Experiment 2), and N = 140 four-, seven-, and eleven-month-old infants (Experiment 3; all predominantly White, 81 females, data collected in 2013-2020) participated in a fast periodic visual stimulation…

Cross-situational word learning, the ability to decipher word-referent links over multiple ambiguous learning events, has been documented across development and proposed to be key to vocabulary acquisition. However, this work has largely focused on learning from one-to-one structure, where each referent is consistently linked with a single label.…

For children, Object Relative (OR) clauses can be late acquired across a number of languages (e.g., this is the goat that the cows are pushing), and production of non-standard ORs that include resumption is often attested (e.g., Italian; French; English). In addition, starting at age 6, children start adopting passive subject relatives (SRs)…

Healthy aging often entails a decline in cognitive and motor functions, affecting independence and quality of life in older adults. Brain stimulation shows potential to enhance these functions, but studies show variable effects. Previous studies have tried to identify responders and non-responders through correlations between behavioral change and…

This study examines the impact of manipulation on the performance of 3.5- and 4-year-old children in the Give-N task with concrete representations (sets of bottle caps and pictures of dots) and spoken number words. In this task, children were asked to give a certain number of items (cookies) using the three representational formats. Children were…

Individual differences in cognitive performance depend on age, skill, and type of task. Nonetheless, whether performance is measured with accuracy (ACC) or with the trade-off between responding speed and accuracy (SAT) could render subtle different relationships. Age and skill might associate more strongly with SAT performance in reasoning tasks,…

The present study used a novel, well-controlled paradigm to investigate the development of cool, hot-positive, and hot-negative inhibitory control in a sample of children (6- to 11-year-old; N = 38, 21 females), adolescents (12- to 18-year-old; N = 38, 24 females), and adults (19- to 38-year-old; N = 38, 28 females; sample location: United…

The widely utilized Global Positioning System (GPS) plays a crucial role in everyday navigation. The literature has predominantly focused on GPS use for reaching destinations rather than exploring its various strategic applications and relations with individual factors. The current paper is intended to develop a GPS Uses Scale assessing a variety…
