“…5,6,8 Others take an opposite stance. Asperger syndrome and autism present with distinct verbal styles, [18][19][20] motor signs, 21 emotion perception 22 and pragmatic reasoning. 23 There are critical differences in processing strategies adopted by individuals with Asperger syndrome and those with autism.…”

“…However, there are exceptions to this positive description. Even as adults, people with ASD are slower than age- and IQ-matched peers at identifying atypical category members (Gastgeb, et al, 2006), and they generate fewer exemplars in semantic fluency tasks (e.g., name all the animals you can think of within 1 min) than unaffected adults with similar levels of language comprehension (Spek, Schatorjé, Scholte, & van Berckelaer-Onnes, 2009). …”

Purpose How do children with autism spectrum disorders (ASD) extend a noun to the category of objects it labels? Given their tendency to perceive locally, their extensions might be too narrow. Given their social-communicative deficits and a context in which the knowledge of a social-communicative partner promotes narrow extensions, their extensions might be too broad. Method We tested these predictions by comparing 25 high-functioning school-aged children with ASD to 29 age-matched peers with typical development (TD) in a task that required extraction of commonalities of object referents and use of social-communicative context to support the category inference. Results The children with ASD readily extended a given noun to multiple exemplars, thereby demonstrating tacit knowledge that words label categories and the ability to override local perceptual biases they might have. However, unlike their peers with TD, those who had concomitant weaknesses in semantic and syntactic language ability formed broad categories when their social partner’s behavior suggested narrow categories. Conclusions Some, but not all, people with ASD fail to use social context to support inferences about word extension. The direction of any causal relationship between failure to use social contextual cues and language deficits awaits determination.

“…We decided to use a single letter “F” in order to minimize the amount of testing time and based on reports in the literature that results obtained with letter “F” tend to be similar to those obtained with 3-letter combinations (Ruff et al, 1996; Tombaugh, Kozak, & Rees, 1999) and thus is frequently used in clinical settings as a bedside test (Lezak et al, 2004). While this pilot study was not designed to assess concurrent and predictive validity of SVF and PVF testing, these tests have been well established and widely used for assessment of cognitive function in populations affected by neurodegenerative disease, traumatic brain injury, developmental disorders, and drug toxicity (Burgess et al, 1998; Doesborgh et al, 2002; Henry & Crawford, 2004a, 2004b, 2004c, 2005; Henry et al, 2004, 2005; Marino et al, 2012; Spek et al, 2009; Witt et al, 2013). Future studies are needed to assess the concurrent and predictive validity of VF testing in the context of cognitive effects of smoking and nicotine withdrawal.…”

“…Word retrieval on both PVF and SVF tests relies on both frontal and temporal cognitive mechanisms; however, PVF relies more heavily on frontal function (working memory, inhibition of inappropriate responses and sustained attention) than SVF, and SVF relies more heavily on temporal function (semantic memory) than PVF. PVF and SVF tests have been widely used in neurological, psychiatric, mental health, and school settings and their construct and ecological validity have been extensively demonstrated (Burgess et al, 1998; Doesborgh et al, 2002; Henry & Crawford, 2004a, 2004b, 2004c, 2005; Henry, Crawford, & Phillips, 2004, 2005; Marino et al, 2012; Spek, Schatorje, Scholte, & van Berckelaer-Onnes, 2009; Witt, Elger, & Helmstaedter, 2013). …”

Mild-to-moderate impairment in frontally mediated functions such as sustained attention, working memory and inhibition have been found to occur during tobacco withdrawal and may present a barrier to successful cessation. These findings have led to studies evaluating cessation treatments that target nicotine withdrawal related cognitive impairment. The instruments currently used to assess cognitive function provide detailed and specific information but have limitations including being time consuming, cumbersome, anxiety provoking and having poor ecological validity. We examined the feasibility of using a mobile computer application to test verbal fluency (VF) as a quick, easy-to-administer and more ecologically valid method of measuring the effects of short-term smoking abstinence on frontally mediated cognitive functions. Thirty participants completed two assessments – one during ad lib smoking and one after overnight abstinence. At each assessment, semantic and phonemic VF tests were administered using a mobile application and nicotine craving and withdrawal symptom severity was assessed. In repeated assessments, performance on both semantic and phonemic VF tests is expected to improve due to practice effects; however, significant improvements were observed only in semantic (p=0.012) but not phonemic (p=0.154) VF. Additionally, the change between assessments in phonemic (but not semantic) score was significantly associated with withdrawal (p=0.006) and craving (p=0.037) severity measured post-abstinence. This study demonstrates that nicotine withdrawal has differential effects on semantic versus phonemic VF suggesting impairments of working memory, attention, and inhibition. These effects were measured using methods easily employed in large groups of participants, potentially with remote test administration and automated scoring.
