Summary
This study reveals early sign language acquisition involves modifications, with handshape changes being most common in young signers. Understanding these phonological changes is key to grasping early signing complexity.
Area of Science:
- Linguistics
- Developmental Psychology
- Sign Language Studies
Background:
- Sign language phonology analysis has focused on features since the 1980s.
- Previous acquisition studies primarily examined handshape, location, and movement.
- The Kata Kolok (KK) sign language in Bali has a vibrant signing community.
Purpose of the Study:
- To analyze the acquisition of phonology in Kata Kolok sign language.
- To apply feature-level analysis to both adult and child signers.
- To investigate modifications in early sign language development.
Main Methods:
- Analysis of longitudinal data from four deaf children in the Kata Kolok Child Signing Corpus.
- Comparison of child sign productions with adult target forms.
- Feature analysis of sign language phonology.
Main Results:
- Handshape modifications were the most frequent, aligning with cross-linguistic patterns.
- Modification rates for other phonological features varied from prior research, potentially due to methodology or KK phonology.
- Observed co-occurrence of modifications within signs suggests interdependencies between features.
Conclusions:
- Early sign language acquisition involves complex modifications beyond just handshape.
- Nuanced approaches are essential for understanding the intricacies of child sign development.
- Findings contribute to the feature-based analysis of sign language phonology in acquisition.

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:24Components of Language
339
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Korotkoff sounds are the specific sounds heard while measuring blood pressure using a sphygmomanometer, typically with a stethoscope or a Doppler device. They are named after Russian physician Nikolai Korotkov, who first described them in 1905. These sounds correspond to turbulent blood flow in the artery as the blood pressure cuff is gradually released after inflation.

01:30Sign Convention
2.3K
When analyzing a beam subjected to various loads, it is crucial to understand the internal forces and moments generated within the structure. These internal forces can be broadly classified into normal forces, shear forces, and bending moments. To determine these forces and moments, we use the method of sections and apply a specific sign convention based on their direction and the side of the section being analyzed.
The normal force acts perpendicular to the beam's cross-section and can...

01:10Introduction to the Sign Test
930
The sign test is an important tool in nonparametric statistics, offering a straightforward yet effective method for analyzing matched pairs, nominal data, or hypotheses concerning the median of a population. It transforms data points into positive or negative signs, avoiding the need for assumptions about data distribution and instead focusing on the direction of change. It is particularly valuable when data does not conform to the normal distribution requirements of many parametric tests. For...

01:12Sign Test for Nominal Data
134
The sign test is a nonparametric method used to evaluate hypotheses about the median of a single sample or to compare the medians of two related samples. The sign test is particularly useful when dealing with nominal data, which includes distinct categories without an inherent order, such as names, labels, and preferences. Nominal data restricts statistical analysis to evaluating population proportions rather than mean or median values that require continuous data.
For example, consider a...
