Yes Classic studies of visual working memory using simple shapes or colored squares have demonstrated that the average person can maintain approximately four items in working memory [3]. Yes A 1 year old can: ü Name some common objects ü Follow simple one-step directions Conceptualization, Participants performed a change detection task that manipulated image familiarity and morph status in a within-subjects design. This chapter focuses on an aspect of semantic knowledge that has not been well studied, its organization into domains. Semantic fluency is believed to be more automatic, as it relies on common rules of categorization, whereas phonemic tasks rely on higher-order cognitive functions. In the verbal domain, this leads to loss of word comprehension and naming, and increasingly degraded and empty speech, though the latter remains fluent and grammatical in output. The few studies that have analyzed the association between these anatomical changes and cognitive performance during adolescence have found better performance associated with white matter diffusion properties [53, 54]. It has been well established that newborns respond to auditory stimuli in the range of language frequencies and show an overt preference for verbal sounds [8, 9], suggesting a biological predisposition to detect and process human language signals. Oral language knowledge may be particularly important for the latter as it functions to supplement partial decoding. The stimuli consisted of the standard images used in Experiment 1. This is a particularly important finding because it suggests an inborn brain asymmetry for language. Children learn a language without effort and completely voluntarily. [43] conducted a study with 160 participants divided into 5 groups according to the school grade they were attending: from 1st to 5th. Mean and (standard deviations) for different verbal fluency tests by age group. Visual working memory is a system that enables us to maintain and manipulate visual information in our minds [1]. Language evolution in adults and changes during senescence are analyzed next. No, Is the Subject Area "Infants" applicable to this article? The issue of language lateralization towards the left hemisphere from birth, however, is not universally supported, as some authors (e.g., Dick et al. Therefore, we tested both younger (aged 4–5 years) and older (aged 6–9 years) children with the standard images to investigate whether the familiarity advantage documented in adults might only emerge in our older group of children, after children have acquired many years of experience with the objects. Thus, Dehaene-Lambertz et al. Two activation patterns distinguish older adults from younger ones, as those authors show (1) bilateral activation of the prefrontal lobes in cognitive tasks that in younger adults is lateralized to one hemisphere and (2) a reduction in occipital-temporal activation with increased activation of the frontal areas. The simultaneous use of two different languages has been seen to be associated with functional brain changes and different connectivity patterns. Semantic development= acquisition of words, their meanings and the links between them ; Process of semantic dev: "strategies formed for learning word meanings and relating them to each other change as their internal representation of language constantly changes and becomes reorganized" The relations between words and their referents The idea that prior knowledge can exert an influence on working memory by providing a way to hierarchically organize the contents of memory has long been noted [2, 19]. Our results suggest that interpreting differences in visual working memory across development requires that the type of stimuli used in the task be taken into account. Analyses of the lateralization of different functions have shown that one of the cognitive functions with the highest lateralization indexes in the left hemisphere is language. [. Kent and Luszcz [89] analyzed 22 cross-sectional studies and one longitudinal study [93] published between 1980 and 2001 on the effects of age, education, and/or gender on BNT performance in younger and older adults. Consistent with this prior work, the present study provides additional evidence that working and long-term memory are not fully independent. Chunking has a robust effect on working memory capacity in adults (see [2] for review), and even infants are able to use their knowledge of familiar categories to improve their visual working memory capacity by chunking arrays of toys [20]. fMRI activation of the left superior temporal lobe (Wernicke’s area) during a receptive language task (discriminating antonyms from synonyms) in a right handed 13-year-old boy. Semantic knowledge, or word and world knowledge is a key area of vocabulary growth. ... Word knowledge is essential in any aspect of second language acquisition (e.g., Nation, 2001). Courtesy Dr. Byron Bernal, Miami Children’s Hospital, Radiology Department, Miami, FL, USA. However, children gain increasing experience with these objects over the years. fMRI recording was performed simultaneously. However, 16-to-17-year-old subjects name fewer items spontaneously and require more functional cues to arrive at the correct answer than do adults aged 18 to 29 years, suggesting not only that the vocabulary required to successfully complete the naming test has been acquired by age 16 to 17 but also that maturation of strategic retrieval functions may still be lacking. [119] found a greater age-related decline in gray matter and a corresponding increase in white matter in boys compared to girls. Also, significant increases in the left frontal lateralization for verb generation with advancing age beginning at age 5 have been reported using magnetoencephalography [42]. Furthermore, gender differences in the maturation rate of both gray and white matter have been reported, with boys showing a faster rate of change than girls [62]. It is noteworthy that, when studying language in general and naming ability in particular, most researchers have focused primarily on children and the elderly, frequently leaving a gap that spans adolescence and early adulthood. Szaflarski et al. See Table 4 for a summary of these studies. In the present study, we found a mnemonic benefit for familiar objects across all age groups. Control conditions ruled out alternative explanations, namely the possibility that the familiar objects could be more easily labeled or that there were differences in low-level visual features between the two types of objects. This review has attempted to elucidate the typical development of language in relation to typical brain development and to reach some conclusions drawn by integrating research from the fields of neuropsychology and neuroimaging. Szaflarski et al. Within each block there were an equal number of same and different trials. From the age of 6 years to puberty (around 12), strategies for generating and integrating information emerge, as does the use of unusual sentences (sophistication of language grammar). This increase, and the related increase in fluency in older children might thus be related to the development of cognitive flexibility. Previous work has provided mixed support for the proposal that semantic knowledge or item familiarity influence working memory. Though this rapid increase in the volume of WM takes place in both hemispheres, a more significant increase in the left language-associated regions (frontotemporal) has been reported in children and adolescents using computational analysis of structural MRI [47].
