Temporal context cues in human fear conditioning: Unreinforced conditional stimuli can segment learning into distinct temporal contexts and drive fear responding
MetadataShow full item record
In associative learning, if stimulus A is presented in the same temporal context as the conditional stimulus (CS) - outcome association (but not in a way that allows an A–CS association to form) it becomes a temporal context cue, acquiring the ability to activate this context and retrieve the CS-outcome association. We examined whether a CS- presented during acquisition or extinction that predicted the absence of the unconditional stimulus (US) could act as a temporal context cue, reducing or enhancing responding, in differential fear conditioning. Two groups received acquisition (CSx–US, CSa–noUS) in phase 1 and extinction (CSx–noUS; CSe–noUS) in phase 2 (AE groups), and two groups received extinction in phase 1 and acquisition in phase 2 (EA groups). After a delay, participants were presented with either CSa (AEa and EAa groups) or CSe (AEe and EAe groups). Responding to CSx was enhanced after presentation of CSa but reduced after presentation of CSe, suggesting that training was segmented into two learning episodes and that the unreinforced CS present during an episode retrieved the CSx–US or CSx–noUS association. These findings suggest that temporal context cues may enhance or reduce fear responding, providing an exciting new avenue for relapse prevention research.

Extinction during reconsolidation eliminates recovery of fear conditioned to fear-irrelevant and fear-relevant stimuliThompson, A.; Lipp, Ottmar (2017)© 2017 Elsevier LtdExtant literature suggests that extinction training delivered during the memory reconsolidation period is superior to traditional extinction training in the reduction of fear recovery, as it targets the ...
“Prepared” fear or socio-cultural learning? Fear conditioned to guns, snakes, and spiders is eliminated by instructed extinction in a within-participant differential fear conditioning paradigmLuck, Camilla ; Patterson, Rachel R.; Lipp, Ottmar (2020)Across three experiments, we investigated whether electrodermal responses conditioned to ontogenetic fear-relevant (pointed guns) and phylogenetic fear-relevant stimuli (snakes and spiders) would resist instructed extinction ...
Moral choice in an agency framework and related motivational typologies as impacted by personal and contextual factors for financial institutions in China.Woodbine, Gordon F. (2002)In this study an empirical investigation is conducted of the factors affecting moral choice, a necessary antecedent to moral behaviour (or action). The theoretical framework has drawn upon Rest's (1983, 1986) model of ...
