Fast mapping semantic features: performance of adults with normal language, history of disorders of spoken and written language, and attention deficit hyperactivity disorder on a word-learning task

Mental health education on college students' english vocabulary memorization from the perspective of STEAM education

The formation and research of Constructivism theory is another understanding in developing educational psychology. Many problems exist in English vocabulary teaching and learning, which are too common to be noticed, negatively and implicitly impacting Students' English Vocabulary Memorization (EVM). In order to solve these problems, this work studies college Students' EVM from the perspective of Constructivism. Firstly, the literature review and observation method understand the Students' EVM performance and teaching behavior. Secondly, it analyzes the current situation, problems, and reasons for Students' poor EVM abilities. Finally, combined with relevant theories, a college Students' EVM-oriented teaching model is proposed, whose effectiveness is verified by teaching experiments. The experiment recruits100 freshmen, including 60 boys and 40 girls, and lasts half a semester. The average score of the final exam in the experimental group is more than 90, which is better than that in the control group. Then, the SPSS21.0 is used in the independent-samples t-test, finding no significant difference (P < 0.05). Thus, the experimental group's comprehensive English Proficiency Level (EPL) has not been negatively affected. The proposed teaching model can improve Students' EVM efficiency and consolidate their memory. The proposal has important guiding significance for stimulating Students' interest in English vocabulary learning and the quality of vocabulary teaching.

The word learning profile of adults with developmental language disorder

BACKGROUND AND AIMS

Previous investigations of word learning problems among people with developmental language disorder suggest that encoding, not retention, is the primary deficit. We aimed to replicate this finding; test the prediction that word form, not the linking of form to referent, is particularly problematic; and determine whether women with developmental language disorder are better word learners than men with developmental language disorder.

METHODS

Twenty adults with developmental language disorder and 19 age-, sex-, and education-matched peers with typical language development attempted to learn 15 words by retrieval practice. Their retention was measured one day-, one week-, and one month after training.

RESULTS

The participants with developmental language disorder required more exposures to the word-referent pairs than the participants with typical language development to reach mastery. While training to mastery, they made more errors in word form production, alone or in combination with errors in linking forms to the correct referents, but the number of no attempts and pure link errors did not differ by group. Women demonstrated stronger retention of the words than men at all intervals. The developmental language disorder and typical language development groups did not differ at the one-day- and one-month retention intervals but the developmental language disorder group was weaker at the one-week interval. Review via retrieval practice at the one-day and one-week interval enhanced retention at the one-month interval; the review at one week was more beneficial than the review at one day. Women benefitted more from the review opportunities than men but the developmental language disorder and typical language development groups did not differ.

CONCLUSIONS

Adults with developmental language disorder present with weaknesses in the encoding of new words but retention is a relative strength. Encoding word forms is especially challenging but encoding word-to-referent links is not. We interpret this profile, and the evidence of a female advantage, as consistent with the Procedural Circuit Deficit Hypothesis.

IMPLICATIONS

When treating a client with developmental language disorder whose goal is to increase vocabulary knowledge, the interventionist should anticipate the need for multiple exposures to new words within activities that highlight the forms of the words and support their memory and production. Periodic review should serve to support long-term retention.

The evaluation of word-learning abilities in people with developmental language disorder: a scoping review

BACKGROUND

The ability to learn new words is critical in the development of oral and written language, and significantly impacts engagement in social, academic and vocational situations. Many studies have evaluated the word-learning process in people with developmental language disorder (DLD). However, methodologies for assessment are heterogeneous, creating difficulties in synthesizing findings and identifying gaps in the knowledge base.

AIMS

To scope systematically the literature and identify key methodological parameters considered in evaluations of word learning in people with DLD; and to identify gaps in the literature to guide further research in this area.

METHODS & PROCEDURES

Twelve databases were searched and a total of 70 studies that met eligibility criteria were identified. The studies were evaluated according to key parameters that researchers varied in their word-learning methodologies.

MAIN CONTRIBUTION

Most research has focused on word learning in the oral modality, and specifically in children with DLD. Fewer studies have explored word learning in adults and adolescents with DLD, and in the written modality. Depending on the research question and theoretical perspective driving the investigation, methodologies for assessing word learning considered a range of parameters, including words being learned, learning context and cues to support learning in the tasks.

CONCLUSIONS & IMPLICATIONS

This review aggregates a variety of methods used previously to assess word learning. Findings highlight the need for further research to explore areas such as: the learning of varied word types (e.g., adjectives and adverbs); learning in the written modality; and word learning (both oral and written) in adolescents and adults with DLD.

Using ratings to gain insight into conceptual development

PURPOSE

The authors explored a novel technique with potential for assessing conceptual development. Participants rated how "normal" to "really weird" an image was in order to determine whether (a) participants would rate images by amount of variation (slight/significant) from the standard image, (b) participants would treat variation related to different concepts equally, or (c) there would be developmental differences in these ratings. Then, authors asked whether children with specific language impairment (SLI) would demonstrate weaker conceptual skills based on their ratings.

METHOD

Adults and school-age children (with and without SLI) used a 9-point equal-appearing interval scale to rate photographic images of animals. These included standard images and images that altered the animals' shape, pattern, color, and facial morphometry.

RESULTS

Significant differences in ratings were obtained for adults compared with typically developing children and children with SLI compared with their age-matched peers. This is in line with the expectation that adults have stronger representations than children, as do typical children compared with those with SLI. Participants differentially rated images that varied from the standard image (slight/significant) for all parameters except shape.

CONCLUSION

Probing conceptual representations without the need for verbal response has the potential for exploring conceptual deficits in SLI.

MEG correlates of learning novel objects properties in children

Learning the functional properties of objects is a core mechanism in the development of conceptual, cognitive and linguistic knowledge in children. The cerebral processes underlying these learning mechanisms remain unclear in adults and unexplored in children. Here, we investigated the neurophysiological patterns underpinning the learning of functions for novel objects in 10-year-old healthy children. Event-related fields (ERFs) were recorded using magnetoencephalography (MEG) during a picture-definition task. Two MEG sessions were administered, separated by a behavioral verbal learning session during which children learned short definitions about the “magical” function of 50 unknown non-objects. Additionally, 50 familiar real objects and 50 other unknown non-objects for which no functions were taught were presented at both MEG sessions. Children learned at least 75% of the 50 proposed definitions in less than one hour, illustrating children's powerful ability to rapidly map new functional meanings to novel objects. Pre- and post-learning ERFs differences were analyzed first in sensor then in source space. Results in sensor space disclosed a learning-dependent modulation of ERFs for newly learned non-objects, developing 500–800 msec after stimulus onset. Analyses in the source space windowed over this late temporal component of interest disclosed underlying activity in right parietal, bilateral orbito-frontal and right temporal regions. Altogether, our results suggest that learning-related evolution in late ERF components over those regions may support the challenging task of rapidly creating new semantic representations supporting the processing of the meaning and functions of novel objects in children.
