Preliminary Results on the Development of the Perception of Spanish /e/ and /ei/ by Heritage Learners vs. L2 Learners of Spanish in the Classroom

This exploratory study gives a first glance at the development of the perception of the Spanish /e/-/ei/ contrast by heritage learners in comparison to that of L2 learners in the classroom. To this end, two types of semester-long, explicit phonetic instruction training are compared: High Phonetic Variability Training (HPVT) with exposure to multiple sources of speech, and regular standalone phonetics courses with low variability of speech input (LPVT). Data from two identical pre-test and post-test ABX perceptual discrimination tasks were obtained from 27 students, as well as 7 control speakers whose primary language is Spanish. Results show that heritage learners perceive the contrast better than L2 learners, and that HPVT significantly improves the perception of the /e/-/ei/ contrast. Although heritage learners perform close to a native ceiling and do not significantly differ from native controls, the improvement from pre-test to post-test is larger in heritage learners enrolled in HPVT than LPVT training. These results suggest that, although the discrimination accuracy of Spanish /e/ and /ei/ is already high for heritage learners at the pre-test stage, High Phonetic Variability Training can be beneficial in the perceptual development of their heritage language, even matching their accuracy to that of native speakers.

Using Game-Based Learning to Improve Boys' Literacy

This chapter foregrounds an online gamified visual intelligence innovation (eyebraingym) developed to enhance visual processing skills, improve memory and vocabulary, and increase reading fluency. The explicit aim of the innovation is to improve comprehension towards visual intelligence. Ninety-eight Grade 8 learners at a South African Boy's School completed their online development during the 2021 academic year. These learners were part of a group of students participating in a whole school reading and literacy intervention program. The innovation is an integral part of this ongoing project. Their interaction with the innovation consists of 15 sessions completed once or twice a week for 20 – 40 minutes over five months. The results of the project are positive. It shows that most participating students improved their perceptual development and reading speed (VPF) and cognitive development and comprehension skills (CDF). In addition, these outcomes transferred to improved relative efficiency when working with information (AIUF).

The Development of Categorical Perception of Segments and Suprasegments in Mandarin-Speaking Preschoolers

This study investigated the developmental trajectories of categorical perception (CP) of segments (i.e., stops) and suprasegments (i.e., lexical tones) in an attempt to examine the perceptual development of phonological categories and whether CP of suprasegments develops in parallel with that of segments. Forty-seven Mandarin-speaking monolingual preschoolers aged four to six years old, and fourteen adults completed both identification and discrimination tasks of the Tone 1-2 continuum and the /pa/-/pha/ continuum. Results revealed that children could perceive both lexical tones and aspiration of stops in a categorical manner by age four. The boundary position did not depend on age, with children having similar positions to adults regardless of speech continuum types. The boundary width, on the other hand, reached the adult-like level at age six for lexical tones, but not for stops. In addition, the within-category discrimination score did not differ significantly between children and adults for both continua. The between-category discrimination score improved with age and achieved the adult-like level at age five for lexical tones, but still not for stops even at age six. It suggests that the fine-grained perception of phonological categories is a protracted process, and the improvement and varying timeline of the development of segments and suprasegments are discussed in relation to statistical learning of the regularities of speech sounds in ambient language, ongoing maturation of perceptual systems, the memory mechanism underlying perceptual learning, and the intrinsic nature of speech elements.

Odor-driven face-like categorization in the human infant brain

Understanding how the young infant brain starts to categorize the flurry of ambiguous sensory inputs coming in from its complex environment is of primary scientific interest. Here, we test the hypothesis that senses other than vision play a key role in initiating complex visual categorizations in 20 4-mo-old infants exposed either to a baseline odor or to their mother’s odor while their electroencephalogram (EEG) is recorded. Various natural images of objects are presented at a 6-Hz rate (six images/second), with face-like object configurations of the same object categories (i.e., eliciting face pareidolia in adults) interleaved every sixth stimulus (i.e., 1 Hz). In the baseline odor context, a weak neural categorization response to face-like stimuli appears at 1 Hz in the EEG frequency spectrum over bilateral occipitotemporal regions. Critically, this face-like–selective response is magnified and becomes right lateralized in the presence of maternal body odor. This reveals that nonvisual cues systematically associated with human faces in the infant’s experience shape the interpretation of face-like configurations as faces in the right hemisphere, dominant for face categorization. At the individual level, this intersensory influence is particularly effective when there is no trace of face-like categorization in the baseline odor context. These observations provide evidence for the early tuning of face-(like)–selective activity from multisensory inputs in the developing brain, suggesting that perceptual development integrates information across the senses for efficient category acquisition, with early maturing systems such as olfaction driving the acquisition of categories in later-developing systems such as vision.

Occupational for elementary students to raise safety and health awareness at schools and homes

Elementary school children are in a very important development in their life, which includes physical, mental and perceptual development. Therefore, environmental conditions in schools and homes must be able to support this development. One of them needs to build awareness in elementary students about the dangers and risks of Occupational Safety and Health. This educational activity can reduce the risk of elementary students experiencing health and safety problems. Community service methods were carried out through lectures, discussions, and mentoring. In the discussion, many were discussed about ergonomics, sitting position, use of bags, and the presence of gas cylinders in their homes. Furthermore, after this education, elementary students' understanding of K3 also increased.

How our hands shape our minds: Six developmental pathways

In the current, empirically grounded paper, we first explore the ways in which manual actions, that is actions performed with hands and arms such as reaching, grasping, and manipulating objects, shape the mind. Based on recent empirical research, we suggest six embodied developmental pathways which solve unique challenges faced by infants and children during development. I) Co-opted motor simulation allows action anticipation, II) interactive specialisation allows executive control to emerge from reaching and grasping. III) Active exploration and IV) error based-learning facilitate cognition and perception. Action based social interactions facilitate V) language development and VI) gesture comprehension. These pathways exemplify how manual actions and the underlying neural processes controlling actions are used by the infant to structure the world and develop cognitive capacities and learn from interactions with the physical and social world. Through an individual difference, correlational approach, we note that these abilities and processes measured in infancy have long-term associations with cognitive and perceptual development into childhood and beyond.

Cross-Linguistic Interactions in Third Language Acquisition: Evidence from Multi-Feature Analysis of Speech Perception

Research on third language (L3) phonological acquisition has shown that Cross-Linguistic Influence (CLI) plays a role not only in forming the newly acquired language but also in reshaping the previously established ones. Only a few studies to date have examined cross-linguistic effects in the speech perception of multilingual learners. The aim of this study is to explore the development of speech perception in young multilinguals’ non-native languages (L2 and L3) and to trace the patterns of CLI between their phonological subsystems over time. The participants were 13 L1 Polish speakers (aged 12–13), learning English as L2 and German as L3. They performed a forced-choice goodness task in L2 and L3 to test their perception of rhotics and final obstruent (de)voicing. Response accuracy and reaction times were recorded for analyses at two testing times. The results indicate that CLI in perceptual development is feature-dependent with relative stability evidenced for L2 rhotics, reverse trends for L3 rhotics, and no significant development for L2/L3 (de)voicing. We also found that the source of CLI differed across the speakers’ languages: the perception accuracy of rhotics differed significantly with respect to stimulus properties, that is, whether they were L1-, L2-, or L3-accented.
