Aesthetic negativity and choreographic practice
… lens of Theodor Adorno’s theory of the inherent negativity of modernist artworks. Such an approach places Adorno’s ideas at the very centre of the analytical view presented here, albeit via the semiotic (re)articulation of these same ideas in recent work by Christoph Menke. This, in turn, draws …

Effects of Motion on Infants' Negativity Bias in Emotion Perception
The negativity bias is a phenomenon that is characterized by infants being more influenced by, attending more to, and responding to more negative emotion information from the environment than positive emotion information. This study used a Tobii© T60 eye-tracking system to examine differences in 8- …

Applied Error Related Negativity: Single Electrode Electroencephalography in Complex Visual Stimuli
Error related negativity (ERN) is a pronounced negative evoked response potential (ERP) that follows a known error. This neural pattern has the potential to communicate user awareness of incorrect actions within milliseconds. While the implications for human-machine interface and augmented …

Mismatch Negativity as a Marker of Auditory Pattern Separation Integrity in Aging
… in aging? This study examined how the mismatch negativity (MMN), an electrophysiological marker of change detection and encoding, relates to age differences in mnemonic discrimination. The MMN was recorded from 33 young (18–32 years, 18 females) and 30 older (55–86 years, 14 females) adults in a …

Sources of Sexual Knowledge, Sex Negativity, and Sexual Shame: Honors Capstone Thesis
<p>This study examined relations between (a) the sources of people’s knowledge about sex, (b) their trust in information obtained from each source, (c) sex-negative attitudes and misinformation about sex (SNAM), and (d) sexual shame. Using an online questionnaire, 354 participants from a large, …

Generation of mismatch negativity in a sample of treatment-resistant schizophrenia patients
Mismatch negativity (MMN) was recorded in thirteen treatment-resistant schizophrenic patients and age- and gender-matched fourteen healthy controls. The MMN was obtained by subtracting the standard from the deviant event-related potential (ERP) brain wave. Subjects responded to infrequent visual …

Reinforcement Learning and the Error -Related Negativity: A Computational and Neurophysiological Investigation
… has been inferred from the ""Error-Related Negativity,"" a component of the event-related brain potential elicited when human subjects commit errors in reaction-time tasks. It is proposed that the Error-Related Negativity is generated when a negative reinforcement learning signal is conveyed …

The Error-Related Negativity: Evidence for a Neural Mechanism for Error-Related Processing
… a negative-going deflection (the error-related negativity, or ERN) in the event-related brain potential began around the time of error onset and peaked about 100 msec later. It ranged in amplitude from 3 to 10 microvolts, was bilaterally symmetrical, and had a scalp distribution maximal at …

Performance Monitoring: Error Detection and the Error-Related Negativity in Choice-Related Time Tasks
… event-related brain potential, the error-related negativity (ERN), appears to be a manifestation of a process that monitors the accuracy of performance. Current evidence suggests that the component is generated in the anterior cingulate cortex. In choice reaction time tasks, the monitoring process …

Negativity and Positivity Biases in Product Evaluations: The Impact of Consumer Goals and Prior Attitudes
… but inconsistent with extant theories of the negativity and positivity effects is provided, and four experiments are conducted to systematically test this explanation against the extant theories of negativity and positivity effects. Results indicate that selective hypothesis testing is a …

Positivity Beyond Absence of Negativity: Social Competence Mediates the Association Between Positive Parenting and Adolescent Friendship Quality
Parenting is important for adolescent friendship development. However, previous research has focused on the adverse effect of negative parenting on adolescents' behavioral problems that undermines their friendships (e.g., Cook et al., 2012). Positive parenting, beyond the absence of negative …

Depressive Feedback Utilization: The Feedback-Related Negativity as an Index of the`Catastrophic Response to Perceived Failure'
… The current study examined the Feedback-Related Negativity (FRN), an event-related potential (ERP) component observed following errors and in response to error feedback, as a possible index of this depressive response to feedback. Thirty undergraduate volunteer participants with extreme scores on …

Buddhist Śūnyatā and Christian Apophaticism : A Typology of Negativity with Special Reference to Derridean Khôra and Différance
… that a typology, specifically a typology of negativity, allows for a nuanced analysis into the comparative possibilities in Buddhism and Christianity. Within the larger scope of a typology <br/>of negativity, the teaching of emptiness, or śūnyatā, is examined in various traditions to have a …

Top-down and Bottom-up influences on ACC activation: Evaluation of a proposed model of the feedback-related negativity
The Feedback-Related Negativity (FRN) is thought to reflect the dopaminergic prediction error signal from the subcortical areas to the ACC (i.e., a bottom-up signal). Two studies were conducted in order to test a new model of FRN generation, which includes direct modulating influences of medial PFC …

The Feedback-Related Negativity is a Time-Dependent Brain Mechanism that Facilitates Aversive Learning: Implications for the Reinforcement Learning FRN Hypothesis
… of feedback-locked EEG. The feedback-related negativity (FRN), a mediofrontal ERP component thought to convey a PE signal, showed robust changes in activation over time but did not respond to trial-by-trial magnitude of prediction errors. This time-dependent change was evident only for reward …

Design of elastic metamaterials
… on the design and fabrication of a double negativity and three broadband single negativity elastic metamaterials using a 3D printer. We investigated dispersion curves and dynamic material properties of the metamaterials. Negative phase velocity in the double negativity metamaterial was also …

Employment and Welfare-to-Work Training Initiatives: The Effects of Pre-Training Attitudes on Job-Search Behavior, Employment Status, and Job-Search Intended Effort
… employment commitment, and unemployment negativity. The study then examined the relationship between these variables and post-training job-search behavior, employment status, and job-search intended effort of unemployed trainees. The behavioral plasticity hypothesis was also explored in …

Clinical Impact of A Highly Sensitive Next-Generation Sequencing Measurable Residual Disease Assay In Patients With Acute Lymphoblastic Leukemia

The Unconscious Influence of Mortality Salience on Younger and Older Adults
… as compared to those who were primed with negativity, regardless of age. Socioemotional selectivity theory, however, predicts that these defenses may also emerge when older adults are primed with negativity due to the increased tendency for older adults, relative to younger adults, to …
