Early processing of orthographic language membership information in bilingual visual word recognition: Evidence from ERPs
Publication date: Available online 22 July 2017 Source:Neuropsychologia Author(s): Liv J. Hoversten, Trevor Brothers, Tamara Y. Swaab, Matthew J. Traxler For successful language comprehension, bilinguals often must exert top-down control to access and select lexical representations within a single language. These control processes may critically depend on identification of the language to which a word belongs, but it is currently unclear when different sources of such language membership information become available during word recognition. In the present study, we used event-related potentials to investigate the time cou...

No effect of hippocampal lesions on stimulus-response bindings
Publication date: Available online 21 July 2017 Source:Neuropsychologia Author(s): Richard N. Henson, Aidan J. Horner, Andrea Greve, Elisa Cooper, Mariella Gregori, Jon S. Simons, Sharon Erzinçlioğlu, Georgina Browne, Narinder Kapur The hippocampus is believed to be important for rapid learning of arbitrary stimulus-response contingencies, or S-R bindings. In support of this, Schnyer et al., 2006 (Experiment 2) measured priming of reaction times (RTs) to categorise visual objects, and found that patients with medial temporal lobe damage, unlike healthy controls, failed to show evidence of reduced priming when resp...

Neural stability: A reflection of automaticity in reading
Publication date: Available online 21 July 2017 Source:Neuropsychologia Author(s): Silvia Siu-Yin Lam, Travis White-Schwoch, Steven G. Zecker, Jane Hornickel, Nina Kraus Automaticity, the ability to perform a task rapidly with minimal effort, plays a key role in reading fluency and is indexed by rapid automatized naming (RAN) and processing speed. Yet little is known about automaticity's neurophysiologic underpinnings. The more efficiently sound is encoded, the more automatic sound processing can be. In turn, this automaticity could free up cognitive resources such as attention and working memory to help build an integrat...

Toddlers show sensorimotor activity during auditory verb processing
Publication date: Available online 19 July 2017 Source:Neuropsychologia Author(s): Katharina Antognini, Moritz M.

Social cognition impairments after aneurysmal subarachnoid haemorrhage: associations with deficits in interpersonal behaviour, apathy, and impaired self-awareness
In conclusion, emotion recognition, ToM and empathy were clearly impaired in aSAH patients and these deficits were related to apathy and deficits in interpersonal behaviour as reported by proxies and to impaired self-awareness. This association strengthens the assumption of impaired social cognition as an underlying construct of behavioural problems after aSAH. Consequently, social cognition tests and proxy-ratings should be used in clinical practice, irrespective of lesion location on MRI or aneurysm circulation, to improve the detection and treatment of apathy and deficits in interpersonal behaviour after aSAH.

Predictability of action sub-steps modulates motor system activation during the observation of goal-directed actions
This study used EEG and eye-tracking to investigate whether and how predictability of an observed action modulates motor system activation as well as behavioral predictions in the form of anticipatory eye-movements. Participants were presented with object-directed actions (e.g., making a cup of tea) consisting of three action steps which increased in their predictability. While the goal of the first step was ambiguous (e.g., when making tea, one can first grab the teabag or the cup), the goals of the following steps became predictable over the course of the action. Motor system activation was assessed by measuring attenuat...

Abnormal Semantic Knowledge in a Case of Developmental Amnesia
Publication date: Available online 16 June 2017 Source:Neuropsychologia Author(s): Anna Blumenthal, Devin Duke, Ben Bowles, Asaf Gilboa, R. Shayna Rosenbaum, Stefan Köhler, Ken McRae An important theory holds that semantic knowledge can develop independently of episodic memory. One strong source of evidence supporting this independence comes from the observation that individuals with early hippocampal damage leading to developmental amnesia generally perform normally on standard tests of semantic memory, despite their profound impairment in episodic memory. However, one aspect of semantic memory that has not been exp...

Speech-in-noise perception in unilateral hearing loss: relation to pure-tone thresholds and brainstem plasticity
Publication date: Available online 13 June 2017 Source:Neuropsychologia Author(s): Nicolas Vannson, Chris J. James, Bernard Fraysse, Boris Lescure, Kuzma Strelnikov, Olivier Deguine, Pascal Barone, Mathieu Marx We investigated speech recognition in noise in subjects with mild to profound levels of unilateral hearing loss. Thirty-five adults were evaluated using an adaptive signal-to-noise ratio (SNR50) sentence recognition threshold test in three spatial configurations. The results revealed a significant correlation between pure-tone average audiometric thresholds in the poorer ear and SNR thresholds in the two conditions...

Acting, seeing, and conscious awareness
Publication date: Available online 13 June 2017 Source:Neuropsychologia Author(s): R.E. Passingham, H.C. Lau We argue that there is a relation between the judgements that ‘I did it’ and ‘I saw it’. Both are statements are about the individual, not just the world. We show that the dorsal prefrontal cortex is activated both when human subjects judge that they are the agents of their actions and when they judge that they are confident that they have seen a masked visual stimulus. Macaque monkeys have also been taught to report whether they have or have not seen visual stimuli and cells can be found in...
