Summary
Morphemic units are crucial for beginning readers to recognize words. As reading skills improve, readers process word morphology more abstractly, moving beyond simple visual cues.
Area of Science:
- Cognitive Psychology
- Developmental Psychology
- Linguistics
Background:
- Beginning readers' word recognition processes are not fully understood.
- The role of sublexical units, specifically morphemes, in early reading is under investigation.
- Understanding morpheme use in French word processing is key to reading development.
Purpose of the Study:
- To examine the role of morphemic units in initial word recognition for beginning readers.
- To assess the extent to which morphemes are used in processing French words.
- To determine how morpheme use in word recognition varies with reading proficiency.
Main Methods:
- Two experiments utilized a variable-viewing-position technique to study word recognition.
- Participants included second graders, fourth graders, and adult readers to track developmental changes.
- Perceptual and morphological effects on word recognition were analyzed.
Main Results:
- Optimal word identification occurred near the word's center, with effects modulated by age and word properties.
- Lexical decisions were increasingly influenced by morphological structure with developing reading skill.
- Children relied on orthographic morpheme information (surface morphology), while proficient readers used abstract morphological processing.
Conclusions:
- Morphemic units are vital in the early stages of word identification for developing readers.
- Morphological representations become more independent of orthography as reading ability increases.
- Findings support the 'word and affix' model of reading development.

01:10Higher Mental Functions of the Brain: Language
729
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...

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

01:28Lateralization
303
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

01:27Language and Cognition
321
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
