Fear Conditioning to Subliminal Fear Relevant and Non Fear Relevant Stimuli
A growing body of evidence suggests that conscious visual awareness is not a prerequisite for human fear learning. For instance, humans can learn to be fearful of subliminal fear relevant images--images depicting stimuli thought to have been fear relevant in our evolutionary context, such as snakes, spiders, and angry human faces. Such stimuli could have a privileged status in relation to manip...
متن کاملAre fear memories erasable?–reconsolidation of learned fear with fear-relevant and fear-irrelevant stimuli
Recent advances in the field of fear learning have demonstrated that a single reminder exposure prior to extinction training can prevent the return of extinguished fear by disrupting the process of reconsolidation. These findings have however proven hard to replicate in humans. Given the significant implications of preventing the return of fear, the purpose of the present study was to further s...
متن کاملInfants’ fear-relevant learning 1 Running Header: INFANTS’ FEAR-RELEVANT LEARNING The origins of snake and spider fear: How infants learn to associate evolutionary fear-relevant stimuli and paired stimuli
Previous research has demonstrated that female infants are capable of learning paired associations between predatory and emotional stimuli that male infants do not learn (Rakison, in review). These findings come in conjunction with evidence pointing towards inherent evolutionary psychological learning mechanisms that allow for the rapid detection of, attending to, and learning about predatory a...
متن کاملThe renewal of extinguished conditioned fear with fear-relevant and fear-irrelevant stimuli by a context change after extinction.
The acquisition, extinction, and subsequent recovery of conditioned fear can be influenced by the nature of the conditional stimulus (CS) and the context in which the CS is presented. The combined effects of these factors were examined in a differential fear-conditioning procedure with humans. Fear-relevant or fear-irrelevant CSs were followed by a shock unconditional stimulus (US) during acqui...
متن کاملThe Origins of Snake and Spider Fear: How Infants Learn to Associate Evolutionary Fear-Relevant Stimuli and Paired Stimuli
Previous research has demonstrated that female infants are capable of learning paired associations between predatory and emotional stimuli that male infants do not learn (Rakison, in review). These findings come in conjunction with evidence pointing towards inherent evolutionary psychological learning mechanisms that allow for the rapid detection of, attending to, and learning about predatory a...
