TLDR
Performance of Alzheimer patients on tests of various aspects of semantic memory, including word finding, knowledge of the semantic attributes, and associates of concepts, as well as their category membership is reviewed.Abstract:
Patients with Alzheimer's disease have been suggested to have a semantic memory impairment not present in the normal old. This article reviews the performance of Alzheimer patients on tests of various aspects of semantic memory, including word finding, knowledge of the semantic attributes, and associates of concepts, as well as their category membership. The effect that semantic context has on cognitive processes such as lexical and semantic priming and memory encoding is also reviewed. Finally, the ability of theoretical constructs such as implicit memory and automaticity to explain intertask variability in Alzheimer patients' semantic performance is discussed.read more

Semantic dementia. Progressive fluent aphasia with temporal lobe atrophy.
TL;DR: The authors report five patients with a stereotyped clinical syndrome characterized by fluent dysphasia with severe anomia, reduced vocabulary and prominent impairment of single-word comprehension, progressing to a stage of virtually complete dissolution of the semantic components of language.

A neural dissociation within language: Evidence that the mental dictionary is part of declarative memory, and that grammatical rules are processed by the procedural system
Michael T. Ullman,Suzanne Corkin,Marie Coppola,Gregory Hickok,John H. Growdon,Walter J. Koroshetz,Steven Pinker +6 more
TL;DR: Evidence is presented that the lexicon is part of a temporal-parietalhnedial-temporal declarative memory system and that granlmatical rules are processed by a frontamasal-ganglia procedural system.

Verbal fluency performance in dementia of the Alzheimer's type: a meta-analysis.
TL;DR: The semantic memory deficit in DAT qualifies as a differential deficit, but executive dysfunction as indexed by phonemic fluency does not constitute an additional isolated feature of the disorder.

Learning and inference in the brain
TL;DR: Hierarchy generative models enable the learning of empirical priors and eschew prior assumptions about the causes of sensory input that are inherent in non-hierarchical models, but are not necessary in a hierarchical context.

Semantic memory impairment in Alzheimer's disease: failure of access or degraded knowledge?
TL;DR: Analysis of the errors made by each patient across the different tests, revealed a significant correspondence between the individual items, offering compelling evidence that the semantic breakdown in DAT is caused by storage degradation.

A spreading-activation theory of semantic processing
TL;DR: The present paper shows how the extended theory can account for results of several production experiments by Loftus, Juola and Atkinson's multiple-category experiment, Conrad's sentence-verification experiments, and several categorization experiments on the effect of semantic relatedness and typicality by Holyoak and Glass, Rips, Shoben, and Smith, and Rosch.

Elements of episodic memory
TL;DR: In this paper, the authors present an EPISODIC/SEMANTIC DISTINCTION and a general overview of the ECPHORY system in a general framework.

Controlled and Automatic Human Information Processing: 1. Detection, Search, and Attention.
TL;DR: A series of studies using both reaction time and accuracy measures is presented, which traces these concepts in the form of automatic detection and controlled, search through the areas of detection, search, and attention and resolves a number of apparent conflicts in the literature.
