10 Questions
What do inflectional meanings in English indicate?
Plurality, possession, gender, and size
What is the primary difference between inflectional and derivational meanings in English?
Inflectional meanings do not change the grammatical category of the stem, while derivational meanings do
Which type of words have no limitations in the meanings that can be expressed?
Open-class words
What is a characteristic of close-class words in English?
They behave rather like grammatical morphemes
What does Latent Semantic Analysis (LSA) count to create a high-dimensional vectorial model?
The frequency with which a word appears in a given context
What is the main difference between online and offline measures in experimental psychology?
Online measures examine activity during active processing, while offline measures are based on information collected after processing is completed
What characterizes saccades in the context of rapid eye movements?
They stay on a specific spot for 200-300 milliseconds before moving to a different part of a scene
What is the typical timing of the P600 waveform in relation to the eliciting event?
400 milliseconds after the eliciting event
What does the N400 waveform typically indicate in the context of event-related potentials?
Semantic anomaly detection, altering the typical shape of N400
What is the primary capability of fMRI (functional magnetic resonance imaging) in neuroscience research?
Detecting the amount of blood oxygen consumption in specific brain areas
Study Notes
Inflectional Meanings
- Inflectional meanings in English indicate grammatical information, such as tense, case, number, and person.
Inflectional vs. Derivational Meanings
- Inflectional meanings modify a word's grammatical function, whereas derivational meanings change a word's lexical category or create new words.
Open- vs. Close-Class Words
- Open-class words (nouns, verbs, adjectives, adverbs) have no limitations in the meanings that can be expressed, as new words can be added to these categories.
- Close-class words (prepositions, conjunctions, pronouns) are limited in their meanings and have a fixed set of members.
Latent Semantic Analysis (LSA)
- LSA counts the frequency of words co-occurring in a large corpus of texts to create a high-dimensional vectorial model representing semantic relationships.
Online vs. Offline Measures
- Online measures in experimental psychology assess participant responses in real-time, while offline measures assess responses after the experiment.
Rapid Eye Movements (Saccades)
- Saccades are rapid eye movements between fixation points, allowing for efficient visual processing.
Event-Related Potentials (ERP)
- The P600 waveform typically occurs 500-800 milliseconds after the eliciting event, indicating syntactic processing.
- The N400 waveform typically indicates semantic processing difficulties or unexpected lexical meaning.
Neuroimaging Techniques
- Functional magnetic resonance imaging (fMRI) allows researchers to non-invasively localize brain activity associated with specific cognitive processes.
Test your knowledge of inflectional and derivational meanings in English with this quiz. Explore how these morphemes are attached to nouns and verbs, indicating plurality, possession, gender, and size. Understand how derivational meanings change the grammatical category and the range of associated meanings.
