While these previous studies focused on how emotion affects memory for emotionally arousing stimuli, in their arousal-biased competition theory, Mather and Sutherland (2011) [23] argue that how arousal influences memory for non-emotional stimuli depends on the priority of those stimuli at the time of the arousal. Arousal enhances perception and ...
In regard to memory enhancement, participants that were shown a stressful picture, often remembered them a day later, which is in accordance with the theory that negative incidents have lasting effects on our memory. [29] Acute stress can also affect a person's neural correlates which interfere with the memory formation. During a stressful time ...
Loss and gain in anticipated emotions people will experience the outcomes differently depending on the situation. Immediate emotions are considered true emotions which integrates cognition with somatic or bodily components of the autonomic nervous system to express the emotion externally.
This model uses cognitive appraisal as a way to explain responses to stressful events. [5]According to this theory, two distinct forms of cognitive appraisal must occur in order for an individual to feel stress in response to an event; Lazarus called these stages "primary appraisal" and "secondary appraisal".

Emotions, as defined by Damasio, are changes in both body and brain states in response to stimuli. [1] Physiological changes (such as muscle tone , heart rate , endocrine activity , posture , facial expression , and so forth) occur in the body and are relayed to the brain where they are transformed into an emotion that tells the individual ...
Norepinephrine is a huge player in fear memory formation. Recent studies have demonstrated that the blockade of norepinephrine β-adrenergic receptors (β-ARs) in the lateral nucleus of the amygdala interferes with the acquisition of fear learning when given pretraining stimuli but has no effect when applied posttraining or before memory retrieval.
The neural correlates of consciousness (NCC) are the minimal set of neuronal events and mechanisms sufficient for the occurrence of the mental states to which they are related. [2] Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate ...
For example, in an extensive study of a subject with ventromedial frontal lobe damage described in the book Descartes' Error, Damasio demonstrated how loss of physiological capacity for emotion resulted in the subject's lost capacity to make decisions despite having robust faculties for rationally assessing options.
