The mere exposure effect without recognition can depend on the way you look! (2009)

Willems, Sylvie, Dedonder, Jonathan, Van Der Linden, Martial

In line with [Whittlesea, B. W. A., & Price, J. R. (2001). Implicit/Explicit memory versus analytic/nonanalytic processing: Rethinking the mere exposure effect. Memory and Cognition, 26, 547-565], we...

Does implicit memory during anaesthesia persist in children? (2009)

Lopez, Ursula, Habre, W, Laurencon, M, Willems, Sylvie, Schmidt, Christina, Van Der Linden, Martial, ...

Background. Recent studies suggest that implicit memory (especially perceptual implicit memory) persists during adequate general anaesthesia in adults. Studies in children, however, have failed to...

Experimental dissociations between memory measures: Influence of retrieval strategies. (2008)

Willems, Sylvie, Van Der Linden, Martial

The objective of this study was to explore the participants' processing strategies on the mere exposure effect, object decision priming and explicit recognition. In Experiments 1, we observed that...

Implicit/explicit memory dissociation in Alzheimer's disease: the consequence of inappropriate processing? (2008)

Willems, Sylvie, Salmon, Eric, Van Der Linden, Martial

Dual-process theories of recognition posit that perceptual fluency contributes to both familiarity-based explicit recognition and perceptual priming. However, the priming-without-recognition...

Cerebral asymmetries in sleep-dependent processes of memory consolidation (2007)

Peigneux, Philippe, Schmitz, Remy, Willems, Sylvie

Preference for previously seen, unfamiliar objects reflects a memory bias on affective judgment, known as the "mere exposure effect" (MEE). Here, we investigated the effect of time, post-exposure...

The contribution of processing fluency to preference : a comparison with familiarity-based recognition (2007)

Willems, Sylvie, Van Der Linden, Martial, Bastin, Christine

There is a great deal of evidence supporting the idea that, when a stimulus is processed fluently, it is more likely to be judged as pleasant. However, this influence of fluency on preference...

Mere exposure effect : a consequence of direct and indirect fluency-preference links (2006)

Willems, Sylvie, Van Der Linden, Martial

In three experiments, picture quality between test items was manipulated to examine whether subjects' expectations about the fluency normally associated with these different stimuli might influence...

A French adaptation of the UPPS Impulsive Behavior Scale: Confirmatory factor analysis in a sample of undergraduate students (2006)

Van Der Linden, Martial, D'Acremont, Mathieu, Zermatten, Ariane, Jermann, Françoise, Laroi, Frank, Willems, Sylvie, ...

Impulsivity is an important and multifaceted psychological construct. Recently, Whiteside and Lynam (2001) have developed the UPPS Impulsive Behavior Scale that distinguishes four dimensions of...

Investigation of automatic memory during general anesthesia for elective surgery using the process dissociation procedure (2005)

Willems, Sylvie, Iselin-Chaves, Irène A., Jermann, Françoise J., Forster, Alain, Adam, Stéphane, Van Der Linden, Martial

Background: This prospective study evaluated memory function during general anesthesia for elective surgery and its relation to depth of hypnotic state. The authors also compared memory function in...

Shoulder isokinetic profile after Latarjet's technique (2005)

Forthomme, Bénédicte, Willems, Sylvie, Hurlet, Sandrine, Berger, JP, Houben, Ghislain, Croisier, Jean-Louis

The following procedures were performed on 23 patients (15 of them males): a shoulder strength isokinetic evaluation of the internal (IR) and external (ER) rotators (with the shoulder 45 degrees and...

Sensation-seeking and impulsivity in young and older adults' decision making (2003)

Willems, Sylvie, Van Der Linden, Martial, Marczewski, Philippe

The somatic marker hypothesis asserts that decision-making processes involve emotion. Using a gambling task that models real-life decisions, studies showed that old adults perform less efficiently...

Normal mere exposure effect with impaired recognition in Alzheimer's disease (2002)

Willems, Sylvie, Adam, Stéphane, Van Der Linden, Martial

We investigated the mere exposure effect and the explicit memory in Alzheimer's disease (AD) patients and elderly control subjects, using unfamiliar faces. During the exposure phase, the subjects...

Neural and cognitive bases of upper limb apraxia in corticobasal degeneration (2001)

Peigneux, Philippe, Salmon, Eric, Garraux, Gaëtan, Laureys, Steven, Willems, Sylvie, Dujardin, Kathy, ...

OBJECTIVE: To investigate the neural and cognitive bases of upper limb apraxia in corticobasal degeneration (CBD). METHODS: Eighteen patients with CBD underwent a cognitive neuropsychological...

Cerebral asymmetries in sleep-dependent processes of memory consolidation

Peigneux, Philippe, Schmitz, Remy, Willems, Sylvie

Preference for previously seen, unfamiliar objects reflects a memory bias on affective judgment, known as the “mere exposure effect” (MEE). Here, we investigated the effect of time, post-exposure...
