An increased fear response may be due to enhanced fear memory or enhanced anxiety-like behavior, a decreased fear response may be due to impaired fear memory or less anxiety, while a minor change or non-change in fear response, such as in 36 trials-triggered fear response in current study, may be due to a mixture of impaired fear memory and enhanced anxiety-like behavior.
Some revealed a general increase of fear reactions, both to the fear (CS+) and the safety stimulus (CS−), whereas other studies discovered a differential return of fear with enhanced fear responses to the CS+ only.
We found matching results for the static S1 faces: fearfulness of static S1 faces (28%, 45%, or 63%) strongly enhanced fear perception of S2 faces, reflected by a significant main effect of static S1 fearfulness, F2,40 = 13.93, MSE = 0.09, P < 0.0001.
Or did the crisis actually reduce immigrant work injury and fatality rates relative to those experienced by natives due to a greater reduction in immigrant employment and/or an enhanced fear of misreporting?
A high HA individual is characterized by an enhanced fear of uncertainty, by pessimism, extensive worries, shyness and proneness to fatigue.
The enhanced fear response of HAB mice was attenuated by treatment with either the α2,3,5-subunit selective benzodiazepine partial agonist L-838,417, corticosterone or the selective neurokinin-1 receptor antagonist L-822,429.
To our knowledge, this is the first study demonstrating a reduction of enhanced conditioned fear responses in a psychopathological mouse model of trait anxiety through use of this drug.
An important aim currently in the fear and anxiety field is the identification of the HDAC isoform(s) contributing to or mediating enhanced fear extinction.
Neutralization of FGF2 revealed that astrocyte-secreted FGF2 mediated stress-hormone-induced NPC proliferation. 2 weeks, but not 2 days, after acute stress, rats also showed enhanced fear extinction memory coincident with enhanced activation of newborn neurons.
This, along with the widely accepted myth of the sex-crazed black male, enhanced fears that white ladies seeing them might be, well, impressed.
