Summary
This study provides the first chronometric evidence on Tongan language production. Findings suggest the phoneme, not the mora, is the initially selected unit during Tongan phonological encoding.
Area of Science:
- Psycholinguistics
- Phonology
- Language Production
Background:
- The role of the mora in Tongan phonological encoding has been debated.
- Previous research in other languages used the picture-word naming paradigm to investigate the initially selected unit during phonological encoding (IPU).
Purpose of the Study:
- To provide the first chronometric evidence on Tongan language production.
- To investigate whether the mora or the phoneme serves as the IPU in Tongan.
Main Methods:
- Utilized a picture-word naming paradigm with Tongan native speakers.
- Presented participants with pictures and superimposed non-word distractors.
- Measured naming latencies to assess the IPU.
Main Results:
- Both onset and mora overlapping distractors led to faster naming latencies compared to control distractors.
- Alternative explanations such as English proficiency were considered.
Conclusions:
- Tongan phonological encoding likely uses the phoneme as the IPU.
- The mora does not appear to be the primary unit selected during initial phonological encoding in Tongan.

235
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

01:24Components of Language
357
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.

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

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...

01:10Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

203
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...
