INTRODUCTION Even though people with congenital prosopagnosia (CP) never develop a normal ability to "overtly" recognize faces, some individuals show indices of "covert" (or implicit) face recognition. The aim of this study was to demonstrate covert face recognition in CP when participants could not overtly recognize the faces. METHODS Eleven people with CP completed three tasks assessing the...

Research on neural mechanisms of attention has generally instructed subjects to direct attention covertly while maintaining a fixed gaze. This study combined simultaneous eye tracking and electroencephalogram (EEG) to measure neural attention responses during exogenous cueing in overt attention shifts (with saccadic eye movements to a target) and compared these with covert attention shifts (res...

In this paper we argue for the existence of covert pied-piping in wh-questions through a previously unnoticed pattern of intervention effects in superiorityobeying English multiple wh-questions. We show that the preference of covert pied-piping is for movement of larger constituents, unlike overt pied-piping. We argue that this discrepancy stems from conflicting requirements of PF and LF: overt...

This paper argues that "covert" operations like Quantifier Raising (QR) can precede "overt" operations. Specifically we argue that there are overt operations that must take the output of QR as their input. If this argument is successful there are two interesting consequences for the theory of grammar. First, there cannot be a "covert" (i.e. post-spellout) component of the grammar. That is, what...

Although there is consensus that the left hemisphere plays a critical role in language processing, some questions remain. Here we examine the influence of overt versus covert speech production on lateralization, the relationship between lateralization and behavioural measures of language performance and the strength of lateralization across the subcomponents of language. The present study used ...

A distributed network of cortical and subcortical brain areas controls our oculomotor behavior. This network includes the superior colliculus (SC), which coordinates an ancient visual grasp reflex via outputs that ramify widely within the brainstem and spinal cord, accessing saccadic and other premotor and autonomic circuits. In this Review, we discuss recent results correlating subliminal SC a...

conclusions acupressure is recommended as a complementary therapy to reduce anxiety in patients with cancer because of its low cost, safety, and simplicity. results according to the findings, the mean level of anxiety before the intervention between groups were matched (p > 0.05). acupressure had a significant influence on the anxiety in the experimental group at 5 (45.30 ± 7.14) and 10 days (4...
