Irrelevant Stimuli and Action Control: Analyzing the Influence of Ignored Stimuli via the Distractor-Response Binding Paradigm
Published on: May 14, 2014
[Influence of interfering stimuli on contingent negative variation]
Summary
Interfering stimuli prolonged the contingent negative variation (C.N.V.) in subjects. This prolonged C.N.V. response may serve as a stress threshold indicator.
Area of Science:
- Neuroscience
- Psychophysiology
Context:
- Investigates the impact of interfering stimuli on electrophysiological responses.
- Utilizes labyrinthine stimulation and arithmetic tasks as experimental stressors.
Purpose:
- To examine how interfering stimuli influence contingent negative variation (C.N.V.).
- To explore the potential of C.N.V. prolongation as a stress indicator.
Summary:
- A statistically significant prolongation of C.N.V. was observed after the S2 response when interfering stimuli (labyrinthine stimulation and arithmetic task) were introduced.
- The study demonstrates a measurable psychophysiological change in response to cognitive and sensory interference.
Impact:
- Suggests that C.N.V. prolongation can be a criterion for determining an individual's stress threshold.
- Provides insights into the neurophysiological correlates of stress and cognitive load.

Feedback Inhibition
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!
Frequency-dependent Selection
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...
Operant Conditioning
Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

Avoidance Learning and Learned Helplessness
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Instinctive Drift
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...
Negative and Cognitive Symptoms of Schizophrenia
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
