Indices of marital discord and mother-child affective processes were used to predict levels of negativity children displayed with unfamiliar peers. Thirty-nine mothers and their 5-year-olds were observed with 5–7 other mother-child dyads during a 30-minute free play session. Mother and child negativity were coded and two types of marital discord were assessed via mother self-report: affiliative...
Mismatch negativity is generated automatically, and is an early monitoring indicator of neuronal integrity impairment and functional abnormality in patients with brain injury, leading to decline of cognitive function. Antipsychotic medication cannot affect mismatch negativity. The present study aimed to explore the relationships of mismatch negativity with neurocognition, daily life and social ...
New perspectives in cognitive1,2 and clinical3,4 neuroscience have been opened up with the recent discovery of mismatch negativity (MMN),5 an auditory event-related brain potential (ERP) elicited by infrequent deviant sounds occurring in a sequence of repeated tones.1 The MMN appears as a negative displacement on the ERP to deviant sounds relative to that to standard sounds, with a peak latency...
We explore entanglement negativity, a measure of the distillable entanglement contained in a quantum state, in relativistic field theories in various dimensions. We first give a general overview of negativity and its properties and then explain a well known result relating (logarithmic) negativity of pure quantum states to the Rényi entropy (at index 1/2), by exploiting the simple features of e...
To study the contribution of the Stimulus-Preceding Negativity (SPN) to the late wave of the Contingent Negative Variation (CNV), negativity was recorded preceding an instruction stimulus (S1), an instruction stimulus to which a motor response was required (S2) and a stimulus that transmitted Knowledge of Results (KR). All recorded negativities showed a centro-parietal maximum. The pre-instruct...
