  2. Inner Speech Deficits in People with Aphasia.Peter Langland-Hassan, Frank R. Faries, Michael J. Richardson & Aimee Dietz - 2015 - Frontiers in Psychology 6:1-10.
    Despite the ubiquity of inner speech in our mental lives, methods for objectively assessing inner speech capacities remain underdeveloped. The most common means of assessing inner speech is to present participants with tasks requiring them to silently judge whether two words rhyme. We developed a version of this task to assess the inner speech of a population of patients with aphasia and corresponding language production deficits. As expected, patients’ performance on the silent rhyming task was severely impaired relative to controls. (...)

  3. Metacognitive Deficits in Categorization Tasks in a Population with Impaired Inner Speech.Peter Langland-Hassan, Christopher Gauker, Michael J. Richardson, Aimee Deitz & Frank F. Faries - 2017 - Acta Psychologica 181:62-74.
    This study examines the relation of language use to a person’s ability to perform categorization tasks and to assess their own abilities in those categorization tasks. A silent rhyming task was used to confirm that a group of people with post-stroke aphasia (PWA) had corresponding covert language production (or “inner speech”) impairments. The performance of the PWA was then compared to that of age- and education-matched healthy controls on three kinds of categorization tasks and on metacognitive self-assessments of their performance (...)

  4. Assessing Abstract Thought and its Relation to Language with a New Nonverbal Paradigm: Evidence From Aphasia.Peter Langland-Hassan, Frank R. Faries, Maxwell Gatyas, Aimee Dietz & Michael J. Richardson - 2021 - Cognition 211:104622.
    In recent years, language has been shown to play a number of important cognitive roles over and above the communication of thoughts. One hypothesis gaining support is that language facilitates thought about abstract categories, such as democracy or prediction. To test this proposal, a novel set of semantic memory task trials, designed for assessing abstract thought non-linguistically, were normed for levels of abstractness. The trials were rated as more or less abstract to the degree that answering them required the participant (...)
