Q

Conduction aphasia (Leitungsaphasie)

A

They hear their own errors but are unable to repair them, they also have problems producing spontaneous speech and repeating speech and sometimes use words incorrectly

May occur when the arcuate fasciculus is damaged

A

Separates frontal and temporal lobes

17
Q

What general area of the brain is associated with language processing?

A

Left-hemisphere regions surrounding the Sylvian fissure

18
Q

Dysarthria

A

A loss of control over articulatory muscles

19
Q

Broca's aphasia

A

Problems fully comprehending grammatically complex sentences, absence of SEVERE comprehension issues

Issues with speaking

20
Q

Broca's area

A

Language production

21
Q

Wernicke's area

A

Language comprehension

22
Q

Wernicke's aphasia

A

Difficulty understanding spoken or written language, sometimes at all

23
Q

Human language is called a _______ language because it arises from the abilities of the brain.

A

natural

24
Q

Phonological

A

Sound-based

25
Q

Orthographic

A

Vision-based

26
Q

The question of how we differentiate auditory sounds into separate words is known as the _______ problem.

A

segmentation

27
Q

Pandemonium model

A

4-stage model for visual stimuli processing where each stage had specific components that represented discrete substages of information processing and that, taken together, would allow a mechanical or biological visual system to recognize patterns.

“Demons” in the biological model correspond to specific neurons or neuronal circuits.

28
Q

3 classes of models that attempt to explain word comprehension:

A

Modular, interactive, hybrid

29
Q

Modular models

A

Claim that normal language comprehension is executed within separate and independent modules

30
Q

Interactive models

A

All types of information can participate in word recognition. In these models, context can have its influence even before the sensory information is available, by changing the activational status of the word-form representations in the mental lexicon

31
Q

Hybrid models

A

Based on the notion that lexical access is autonomous and not influenced by higher-level information, but that lexical selection can be influenced by sensory and higher-level contextual information.

32
Q

Syntactic parsing

A

Assigning syntactic structure to words in sentences

33
Q

N400 response

A

Semantic violation response

34
Q

P600

A

Grammatic violation response

35
Q

Memory unification control model

A

Memory refers to the linguistic knowledge that, following acquisition, is encoded and consolidated in neocortical memory structures.

Unification refers to the integration of lexically retrieved phonological, semantic, and syntactic information into an overall representation of the whole utterance.

Control relates language to social interactions and joint action

36
Q

Lemmas

A

Specify a word's syntactic properties

37
Q

Hierarchical state feedback control (HSFC) model

A

Hickok’s model of speech production involves parallel processing and two levels of hierarchical control.

Input to the HSFC model begins with the activation of a conceptual representation that in turn excites a corresponding word (lemma) representation, just as in linguistic models.

Unlike the situation in some psycholinguistic models, the phonological level is split into a motor and a sensory phonological system.

The word level projects in parallel to sensory (right) and motor (left) sides of two hierarchical levels of feedback control, each with its own internal and external sensory feedback loops.
