Implicit learning is a process of acquiring knowledge that occurs without conscious awareness of learning, whereas explicit learning involves the use of overt strategies. To date, research related to implicit learning following stroke has been largely restricted to the motor domain and has rarely addressed implications for language. The present study investigated implicit and explicit learning of an auditory word sequence in 10 individuals with stroke-induced agrammatic aphasia and 18 healthy… 
Implicit learning and implicit treatment outcomes in individuals with aphasia
TLDR
This study suggests that individuals with agrammatic aphasia demonstrate implicit learning ability; however, this ability does not necessarily promote successful outcomes in treatment that is based solely on implicit training methods.
Statistical learning and its consolidation in persons with aphasia
TLDR
The present study aimed to investigate statistical learning abilities and its consolidation in Persons with Aphasia (PWA) with a focus on implicit learning.
Sequential learning in individuals with agrammatic aphasia: evidence from artificial grammar learning
TLDR
The results suggest that individuals with agrammatic aphasia show sequential learning, but the underlying processes involved in this learning may be different than for healthy adults.
Language recovery in aphasia following implicit structural priming training: a case study
ABSTRACT Background: Individuals with aphasia show difficulty producing sentences as a result of impaired syntactic production. Studies of structural priming in healthy speakers show that long-term
Investigating Attentional Allocation With Eye Tracking During Category Learning in People With Aphasia
Studies have identified deficits in attention in individuals with aphasia in language and nonlanguage tasks. Attention may play a role in the construction and use of language, as well as in learning
Elucidating an implicit learning network in healthy adults during artificial grammar tasks
Implicit learning is the unconscious extraction of rules governing complex stimuli, measured through experiments such as artificial grammar tasks, and is directly related to natural language
Implicit learning of artificial grammatical structures after inferior frontal cortex lesions
TLDR
These findings suggest that the LIFG does not play an exclusive role in the implicit learning of artificial pitch grammars, and the use of non-verbal material and an implicit task reveals cognitive capacities that remain intact despite lesions to the LifG.
Statistical Learning in Aphasia: Preliminary Results from an Artificial Grammar Learning Task
Statistical learning, i.e., the discovery of structure based on statistical properties of stimuli, is considered an implicit process that plays an important role in nonlinguistic and linguistic

Explicit Information Interferes with Implicit Motor Learning of Both Continuous and Discrete Movement Tasks After Stroke
TLDR
The data suggest that certain forms of explicit information delivered before task practice may not be as useful for learning as discovering the solution to the motor task with practice alone, and this is regardless of the type of task being learned.

TLDR
Findings show that implicit learning is intact in dyslexia and should be taken into account when designing training programs for developmental dyslexic readers.

Implicit sequence learning without motor sequencing in young and old adults
TLDR
Results indicate that young and old adults are able to learn purely perceptual auditory sequences, but that explicit knowledge contributes to learning of repeating sequences by young adults.
Providing explicit information disrupts implicit motor learning after basal ganglia stroke.
TLDR
It appears that after basal ganglia stroke explicit information is less helpful in the development of the motor plan than is discovering a motor solution using the implicit system alone, due to the increased demand placed on working memory by explicit information.

Background: Researchers have found that many individuals with aphasia (IWA) present with cognitive deficits that may impact their communication, and perhaps underlie their language-processing
Evidence for implicit sequence learning in dyslexia.
TLDR
The present study examines automatic skill learning in a single task paradigm and extends previous studies by independently examining the contribution of stimulus-based and response-based learning.
Do children with developmental dyslexia have an implicit learning deficit?
TLDR
The children with DD were impaired on both implicit learning tasks, suggesting that the learning deficit observed in dyslexia does not depend on the material to be learned but on the implicit nature of the learning that characterises the tasks.
