The (Spatial) Memory Game: Testing the Relationship Between Spatial Language, Object Knowledge, and Spatial Cognition
Published on: February 19, 2018
Summary
Agrammatism in aphasia may stem from linguistic structure deficits or processing limitations. This study suggests processing limitations better explain difficulties with restrictive relative clauses in agrammatic aphasics.
Area of Science:
- Psycholinguistics
- Neurolinguistics
- Developmental Psychology
Background:
- Agrammatism, a symptom of aphasia, presents a complex challenge in understanding language deficits.
- Two primary models explain agrammatism: a linguistic structure deficit model and a language processing limitation model.
Purpose of the Study:
- To compare the linguistic structure deficit model and the language processing limitation model of agrammatism.
- To investigate the comprehension of restrictive relative clauses in individuals with agrammatism.
Main Methods:
- Literature review on language development, dyslexia, and adult sentence processing.
- Experimental investigations focusing on the processing of restrictive relative clauses across various subject populations.
Main Results:
- Parallel patterns of linguistic behavior were observed across different subject groups when processing restrictive relative clauses.
- Findings indicated that agrammatic aphasics exhibit specific difficulties with comprehending sentences containing restrictive relative clauses.
Conclusions:
- The results support the processing limitation account over the linguistic structure deficit model for agrammatism.
- This suggests that limitations in language processing underlie the difficulties experienced by agrammatic individuals with complex sentence structures.

02:45Functional Groups
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...
00:49Complementation Tests
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

01:16Language
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.

01:24Components of Language
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. “eh”). Phonemes combine to...
01:19Conjugation
Conjugation is a form of horizontal gene transfer that primarily occurs in bacteria and some archaea, promoting genetic diversity and adaptation. Bacteria can acquire resistance genes through conjugative plasmids, allowing them to survive antibiotic treatments that would otherwise be lethal. This process involves direct contact between cells through specialized structures such as the sex pilus and is mediated by conjugative plasmids, including the F (fertility) factor.Conjugation requires...
