Prior studies reported that long-term memory (LTM) was basically unimpaired in individuals with autism. However, people with autism have been found to perform worse than ability-matched controls when verbal materials to be remembered are semantically related. In normal subjects, semantic processing of verbal materials facilitates LTM better than 'shallow' (phonological or perceptual) processing, which is known as the levels-of-processing effect. In this study, the relationship between LTM and… Expand
Impaired Social Processing in Autism and its Reflections in Memory: A Deeper View of Encoding and Retrieval Processes
TLDR
The results suggest that social memory deficits in ASC arise from difficulties both in orienting towards and encoding social content, as well as retaining and retrieving it. Expand
Long-Term Memory in High-Functioning Autism: Controversy on Episodic Memory in Autism Reconsidered
  • M. Toichi, Y. Kamio
  • Psychology, Medicine

TLDR
There was an unusual correlation between LTM performance and a nonverbal measure in the autistic group and the results were discussed in terms of the relation between episodic memory and semantic memory. Expand
Memory in autistic spectrum disorder.
TLDR
It is provisionally concluded that memory profiles in HFA and M-LFA (relative to ability-matched controls) are similar but that declarative memory impairments are more extensive in M- LFA than in H FA, and the urgent need for research on memory in lower functioning individuals is highlighted.

Verbal fluency as a function of time in autism spectrum disorder: An impairment of initiation processes?
TLDR
Supporting the idea that the discrepancy found between an impairment in global word productivity combined with normal clustering and switching strategies is due to an activation and initiation deficit, an abnormal performance for the ASD group in the first time period only is observed. Expand
A specific impairment in cognitive control in individuals with high-functioning autism.
TLDR
Investigation of the hierarchical architecture of control modules in autism using an experimental paradigm based upon a multistage model of executive functions finds that performances in episodic control were associated to the autism spectrum quotient in both groups, suggesting that this episodi control impairment might be at the core of ASDs.

Verbal memory deficits in relation to organization strategy in high- and low-functioning autistic children
Abstract The present study examined the verbal memory profile and its relation to organizational strategies in high-functioning (Hi-AUT) and low-functioning (Lo-AUT) children with autism. Twenty-twoExpand

Neuroenhancement of Memory for Children with Autism by a Mind–Body Exercise
TLDR
The present findings suggest that the mind–body exercise program may have the potential effect on modulating neural functional connectivity underlying memory processing and hence enhance memory functions in individuals with autism. Expand
Memory in autism spectrum disorder: A meta-analysis of experimental studies.
TLDR
Analysis of 64 studies comparing individuals with ASD and typical development showed greater difficulties in ASD compared with TD individuals in STM and episodic long-term memory, and the potential benefit of using verbal materials at encoding and broader forms of memory support at retrieval to enhance performance was acknowledged.

Intact and impaired memory functions in autism.
TLDR
The group with autism performed significantly worse than comparison subjects on measures of temporal order memory, source memory, supraspan free recall, working memory, and EF, but not on short- and long-term recognition, cued recall, or new learning ability, consistent with the predictions of the EF theory.

Semantic processing in the free recall of autistic children: Further evidence for a cognitive deficit
Two memory experiments were conducted with groups of autistic, mentally retarded and normal children, matched on verbal mental age and digit span. In the first experiment free recall of semanticallyExpand

TLDR
Findings on paired-associate learning differ in autistic and amnesic subjects, but findings on recall, recognition and cued recall are comparable. Expand
Neuroanatomical correlates of encoding in episodic memory: levels of processing effect.
TLDR
It is proposed that memory processes are subserved by a wide neurocognitive network and that encoding processes involve preferential activation of the structures in the left inferior prefrontal cortex. Expand
The nature and specificity of the language coding deficit in autistic children.
TLDR
While autistics differed from matched normal children, they did not differ from matched retarded children, and it is suggested that sequences with artificial syntactic and semantic structures should be used to resolve the question of whether autistics have a deficit in processing semantic information. Expand
Increased discrimination of "false memories" in autism spectrum disorder.
TLDR
It is found that individuals with ASD are able to discriminate false memory items from true items significantly better than are control subjects, and this results suggest that semantic representations comprise a less distributed network in high-functioning adults with ASD. Expand
Implicit and Explicit Memory in Autism: Is Autism an Amnesic Disorder?
TLDR
The results do not support the theory that high-functioning autism is a type of medial temporal lobe amnesia, but they suggest that persons with autism use different organizational strategies during encoding or retrieval of items from memory. Expand

TLDR
The results of the word and ideational fluency tasks are suggested to support the hypothesis that individuals with autism are impaired in the generation of novel responses and behaviour, and the results ofThe design fluency task are equally consistent with an impairment in the regulation of behaviour through inhibition and/or monitoring.

TLDR
Only in the autistic group was a significant correlation found between performance for the related items and two nonverbal cognitive measures, which suggests a possibility that semantic processing in individuals with autism might be qualitatively different from that in controls. Expand
