“…Besides, similar results have been reported previously [38,40,41,42,43,44,45,46,47,48]. However, our results concerning AD are not concordant with those of certain other studies [31,33,34,35,36,37].…”

“…Additionally, in a recent meta-analysis study, Millet et al [48] proposed other methodological variations, such as encoding instructions, to explain the discrepancy of WSC priming results in AD. Taking into account the different encoding conditions, the results of that work suggested that completion priming is equivalent to that of the controls when the encoding conditions require semantic judgments or the generation of words.…”

“…Some investigators have reported a priming deficit in AD [30,31,32,33,34,35,36,37], whereas others have found no differences in priming effects between patients with AD and normal control participants [38,39,40,41,42,43,44,45,46,47,48]. Thus, Fleischman and Gabrieli [29] found that 65% of AD studies reported that priming was normal.…”

Lexical priming was examined in patients with Alzheimer's disease and in aphasic patients. Control participants were divided into young and elderly [cf. Arroyo-Anlló et al.: Eur J Cogn Psychol 2004;16:535-553]. For lexical priming, a word-stem completion task was used. Normal elderly participants had lexical priming scores that were significantly lower than those of young individuals. Analysis of covariance with age and educational level as covariates showed that the control participants, aphasic and Alzheimer patients did not differ significantly on the lexical priming task. Our results suggest that performance in the lexical priming task diminishes with physiological aging, but is not significantly affected by mild or moderate Alzheimer's disease or by fluent or non-fluent aphasia.

“…In striking contrast to preserved repetition priming in patients with circumscribed amnesia, patients with Alzheimer’s disease (AD) are impaired on word-stem completion priming tasks (for reviews, see Fleischman, 2007; Fleischman & Gabrieli, 1998; Meiran & Jelicic, 1995; Millet, Le Goff, Bouisson, Dartigues & Amieva, 2010). The neural mechanisms underlying impaired priming in patients with AD have yet to be identified.…”

Repetition priming and cortical arousal in healthy aging and Alzheimer's disease

et al. 2015

Repetition priming refers to a form of implicit memory in which prior exposure to a stimulus facilitates the subsequent processing of the same or a related stimulus. One frequently used repetition priming task is word-stem completion priming. In this task, participants complete a series of beginning word stems with the first word that comes to mind after having viewed, in an unrelated context, words that can complete some of the stems. Patients with Alzheimer’s disease (AD) exhibit a significant deficit in word-stem completion priming, but the neural mechanisms underlying this deficit have yet to be identified. The present study examined the possibility that the word-stem completion priming deficit in AD is due to disruption of ascending neuromodulatory systems that mediate cortical arousal by comparing word-stem completion priming and behavioral measures of spatial orienting and phasic alerting. Results showed that in healthy elderly controls higher levels of phasic alerting were associated with a sharpening of the temporal dynamics of priming across two delay intervals: those with higher levels of alerting showed more immediate priming but less delayed priming than those with lesser levels of alerting. In patients with AD, priming was impaired despite intact levels of phasic alerting and spatial orienting, and group status rather than individual levels of alerting or orienting predicted the magnitude of their stem-completion priming. Furthermore, the change in priming across delays they displayed was not related to level of alerting or orienting. These findings support the role of the noradrenergic projection system in modulating the level of steady-state cortical activation (or “cortical tonus”) underlying both phasic alerting and the temporal dynamics of repetition priming. However, impaired priming in patients with AD does not appear to be due to disruption of this neuromodulatory system.

“…Word completion tasks are widely used to study different aspects of implicit memory in clinical and non-clinical populations (Geraci & Hamilton, 2009;Marques, Spataro, Cestari, Sciarretta, & Rossi-Arnaud, 2016;Mitchell & Bruss, 2003;Millet, Le Goff, Bouisson, Dartigues, & Amieva, 2010;Pomarol-Clotet, Oh, Laws, & McKenna, 2008). In these studies implicit memory has been evaluated through repetition priming, usually defined as the benefit in the processing of a stimulus when it has been recently processed (Roediger & Blaxton, 1987).…”

Spanish norms for completion of restricted length word stems

et al. 2016

View full text Add to dashboard Cite

This study presents a normative database of Spanish restricted length word stems that provides useful information for the selection of stimuli in memory experiments with Word Stem Completion (WSC) tasks. The database includes indices relative to stems (total baseline completion, priming baseline completion, priming, number of completions, ratio between given and deleted letters, and syllabic structure), and indices relative to characteristics of the words used to obtain the stems (frequency, familiarity, number of meanings, length, number of syllables, arousal, and valence). A WSC task was performed by 515 participants to calculate priming and baseline indices. An Exploratory Factor Analysis showed that these indices are grouped in four factors: perceptual, lexical, emotional, and response competition. Stepwise regression analyses performed with these factors showed that the lexical, response competition, and perceptual factors predict priming baseline completion, while only the lexical factor predicts priming. The model that best explains the relationship between priming and priming baseline completion was a cubic model, and the optimum baseline values for achieving priming were between .31 and .36.
