Probability effects on event-related potential correlates of recognition memory.

A common finding in event-related potential (ERP) studies of recognition memory is that recognised items elicit greater positivity at parietal electrode sites than new items (the left parietal old/new effect). Parietal positivity (the P300 or P3b) is ...

Interference with vision by TMS over the occipital pole: a fourth period.

We investigated the effect of single-pulse transcranial magnetic stimulation (TMS) over the occipital pole on a forced-choice visual letter-identification task. Magnetic stimuli were applied on the midline but with the initial current directed ...

Differential remoteness and emotional tone modulate the neural correlates of autobiographical memory.

Autobiographical memory relies on complex interactions between episodic memory contents, associated emotions and a sense of self-continuity along the time axis of ones life history. The neural correlates underlying autobiographical memory are known to ...

Inhibition of subliminally primed responses is mediated by the caudate and thalamus: evidence from functional MRI and Huntingtons disease.

Masked prime tasks have shown that sensory information that has not been consciously perceived can nevertheless trigger the preactivation of a motor response. Automatic inhibitory control processes prevent such response tendencies from interfering with ...

Intrasession and intersession reliability of the quadriceps Hoffmann reflex.

The Hoffmann reflex (H-reflex) is a resting electromyographic (EMG) measurement of motoneuron pool recruitment. While the soleus H-reflex has been studied extensively, the study of the quadriceps H-reflex has been limited for various reasons. To date no ...

Attentional orienting towards smoking-related stimuli.

According to incentive salience theory, conditioned stimuli (CS+) associated with drug reinforcement acquire the capacity to elicit a conditioned attentional orienting response, which controls drug-seeking and drug-taking behaviour. We sought evidence ...

Attentional enhancement opposite a peripheral flash revealed using change blindness.

We describe a new method for mapping spatial attention that reveals a pooling of attention in the hemifield opposite a peripheral flash. Our method exploits the fact that a brief full-field blank can interfere with the detection of changes in a scene ...

Verifying different-modality properties for concepts produces switching costs.

According to perceptual symbol systems, sensorimotor simulations underlie the representation of concepts. It follows that sensorimotor phenomena should arise in conceptual processing. Previous studies have shown that switching from one modality to ...

History matters: the preview benefit in search is not onset capture.

Visual search for a conjunction target is made easier when distractor items are temporally segregated over time to produce two separate old and new groups (the new group containing the target item). The benefit of presenting half the distractors first is ...

Physiological, metabolic, and performance implications of a prolonged hill walk: influence of energy intake.

We aimed to examine the effects of different energy intakes on a range of responses that are relevant to the safety of hill walkers. In a balanced design, 16 men completed a strenuous self-paced mountainous hill walk over 21 km, under either a low-energy ...
