A factorial study of fluency was undertaken to test an hypothesis that at least two fluency abilities would be measured by a battery composed both of word fluency tests used by Thurstone and tests of fluency described by several British investigators.

Twenty-eight tests, including ten reference tests for five primary mental abilities, were administered to high-school by:   The present study focuses on the results of the verbal fluency tasks. Procedure Phonemic task. Subjects were required to generate as many words as possible beginning with the letter P, V or R (Cardebat et al., ) and 2 min were allotted for Cited by: A group of researchers from Japan has applied a novel and affordable neuroimaging modality, optical topography to develop a diagnostic paradigm based on the verbal fluency test (Takizawa et al., ).Optical topography measures the hemodynamic response to cerebral activation, with the additional ability to distinguish the changes in oxy- and deoxy-hemoglobin during a cognitive task.

The results from the present study provide norms for two verbal fluency tests that The teacher ’s word book of 30, carried out by the methods of factor analysis described by Thurstone.

Developmental changes in children's verbal fluency A factor-analysis study of verbal fluency book confrontation naming were explored in this study.

One hundred and sixty children (ages 5 years and 11 months to 11 years and 4 months) completed two verbal fluency tasks (phonemic Cited by: The primary aim of this study was to investigate the cognitive strategies used in semantic fluency (clustering, switching, and access to subcategories) in amnestic mild cognitive impairment (aMCI).

Tests of Verbal Fluency, Czech Normative Study for Older Adults. May ; Ceska a Slovenska Neurologie a Neurochirurgie 78/ (3)–; DOI: /amcsnn Fifty-three tests designed to measure aspects of creative thinking were administered to air cadets and student officers.

The scores were intercorrelated and 16 factors were extracted. Orthogonal rotations resulted in 14 identifiable factors, a doublet, and a residual. Nine previously identified factors were:verbal comprehension, numerical facility, perceptual speed, visualization, general. Instrument: In this study, we applied two subtes ts of TTCT-Verbal Form: subtest 4 (improve a product), and subt est 5 (Unusual Uses); and two subtests of TTCT -Figurative-Form: subt est 2.

A study by Hostetter and Alibali found that the use of “beat gestures” is correlated with higher verbal fluency. “Beat gestures” are small, rhythmic movements that emphasize certain words or phrases without conveying specific information about the meaning of those words or phrases.

Verbal fluency is a cognitive function that facilitates information retrieval from memory. Successful retrieval requires executive control over cognitive processes such as selective attention, selective inhibition, mental set shifting, internal response generation, and self-monitoring.

A young child learning to read uses decoding, or word-breaking, skills in conjunction with fluency, reading texts smoothly and accurately at a good pace with appropriate expression, to best.

Confirmatory factor analysis was performed on the WAIS-III, WRAT-3 Reading, Boston Naming Test, Controlled Oral Word Association Test, Category Fluency, Rey-Osterreith Complex Figure, Visual Form.

The F-A-S Test, a subtest of the Neurosensory Center Comprehensive Examination for Aphasia (NCCEA; Spreen & Benton, ), is a measure of phonemic word fluency, which is a type of verbal assesses phonemic fluency by requesting an individual to orally produce as many words as possible that begin with the letters F, A, and S within a prescribed time frame, usually 1 min (see.

Phonemic and semantic fluency output was scored for word clustering and switching between clusters. Convergent validity analyses using other tests presumed to tap into strategy use (California Verbal Learning Test, Ruff Figural Fluency Test) support scoring of phonemic and semantic clusters on both fluency tasks.

Task-discrepant clustering (e.g. Fluency with Skinner’s Verbal Behavior Terms Fawna Stockwell & John Eshleman The Chicago School of Professional Psychology Chicago, IL Using a deck of 60 Say All Fast a Minute Every Day Shuffled (SAFMEDS) cards, a learner established a fluent verbal repertoire related to the key terms of Skinner’s () analysis of verbal behavior.

This. The aim of the present study was to (a) determine time-dependent patterns of verbal fluency responses, switches, and clusters for single- and multidomain aMCI and naMCI compared with neurologically normal older adults; and (b) investigate relationships between components of verbal fluency ability and neuropsychological factors thought to be.

Verbal fluency describes the rate at which a person can produce words. In a verbal fluency test, someone is given a prompt and a short period of time in which to respond. For example, a patient might be asked to generate a list of animals or a list of words starting with “P” in 60 seconds.

Verbal fluency tests, and in particular initial letter fluency, are widely used as tests of executive dysfunction. Initial letter fluency, also referred to as the Controlled Oral Word Association Test (COWAT), requires the generation of words from initial letters (normally F, A and S) under time constraints, normally 60 seconds per letter.

Executive function is a complex cognitive construct incorporating a number of processes associated with higher-level thought and behaviour which develop across the lifespan (e.g. Diamond and Goldman-Rakic ).Thought to be essential to goal oriented behaviour, executive functions are closely related to other cognitive processes such as memory and attention and are also important in affective.

Verbal fluency tests are a kind of psychological test in which participants have to produce as many words as possible from a category in a given time (usually 60 seconds). This category can be semantic, including objects such as animals or fruits, or phonemic, including words beginning with a specified letter, such as p, for example.

The semantic fluency test is sometimes described as the. For the confirmatory factor analysis, 23 variables of interest were included and are described below.

However, the correlation matrix in the current study indicates that verbal fluency was most highly correlated with language and memory, which has also been shown in other studies (Siedlecki et.

Verbal fluency is an aspect of verbal ability and is the facility to use words quickly and accurately both when speaking and when writing.

Contents. 1 Assessment; Generally, the later in life a learner approaches the study of a foreign language, the harder it is. Inwe published an article on our research expanding on the use of fMRI for cognitive assessment using the Verbal Fluency Test.

This study explains: Creating normative data to standardize fMRI (now fNCI) and the Verbal Fluency Test (f-VFT) for patient evaluation. Of individuals with MCI at baseline identified from consecutive referrals to a memory clinic and compared at with age‐, sex‐, and education‐matched controls (n=), completed 2 years of follow‐up or progressed to AD during the study period.

Measurements. Verbal fluency discrepancy (semantic–phonemic fluency) scores at. Since we've helped behavior analysts become Board certified. We’ve achieved this by applying the scientific principles and methods of applied behavior analysis to the development of instructional content and software.

More specifically, we use goals and specific measurable objectives to teach the discriminations necessary to ensure that those objectives are learned. The aim of this study is to evaluate the effectiveness of a remedial reading program in improving reading fluency and comprehension for elementary school students.

The age groups for the study (fourth through sixth grade) were chosen based on the following two reasons: 1) the importance of fluency and comprehension at this.Verb fluency test provide a useful gradation of impairment from normal aging to MCI and mild AD as reported in previous studies with verbal fluency tests [6, 7, 26, 32, 33, 61].

Consistent with a previous study in healthy Spanish subjects [ 62 ], higher levels of schooling were found related to better verb fluency performances.the verbal fluency test, in which an individual is required to recall items.

Variations of this test include the phonemic verbal fluency (PVF), free fluency, fluency of certain classes of words, alternated fluency, and semantic verbal fluency (SVF) of different semantic categories such as animals, food, fruits and supermarket items.
