The effects of assessment type on verbal ratings of conditional stimulus valence and contingency judgments: implications for the extinction of evaluative learning.
Recent research on causal learning found (a) that causal judgments reflect either the current predictive value of a conditional stimulus (CS) or an integration across the experimental contingencies… Expand
Does Affective Learning Exist in the Absence of Contingency Awareness
Abstract The proposal that affective learning, the learning of likes and dislikes, can exist in the absence of contingency awareness, whereas signal learning, the learning of stimulus relationships,… Expand
No support for dual process accounts of human affective learning in simple Pavlovian conditioning
Dual process accounts of affective learning state that the learning of likes and dislikes reflects a learning mechanism that is distinct from the one reflected in expectancy learning, the learning of… Expand
The Origins of Specific Phobias: Influential Theories and Current Perspectives
Fears are quick and adaptive responses that permit powerful reply to imminent threats. Less adaptive, phobias are extreme manifestations of fear to objects or situations in the absence of a… Expand
Reaction time facilitation by acoustic task-irrelevant stimuli is not related to startle
Previous research has been interpreted to suggest that the startle reflex mediates the RT facilitation observed if intense, accessory acoustic stimuli are presented coinciding with the onset of a… Expand

BACKGROUND Differential diagnosis implies identifying shared and divergent characteristics between clinical states. Clinical work with older adults demands not only the knowledge of nosological… Expand
Stimulus competition in pre/post and online ratings in an evaluative learning design
Evaluative learning is said to differ from Pavlovian associative learning in that it reflects stimulus contiguity, not contingency. Thus, evaluative learning should not be subject to stimulus… Expand
When two paradigms meet: Does evaluative learning extinguish in differential fear conditioning?
Contemporary theories of Pavlovian conditioning propose a distinction between signal learning (SL), in which a conditioned stimulus (CS) becomes a predictor for a biologically significant… Expand
Automatic attention does not equal automatic fear: preferential attention without implicit valence.
Theories of nonassociative fear acquisition hold that humans have an innate predisposition for some fears, such as fear of snakes and spiders. This predisposition may be mediated by an evolved fear… Expand
Are snakes and spiders special? Acquisition of negative valence and modified attentional processing by non-fear-relevant animal stimuli
Previous research has demonstrated differences in processing between fear-relevant stimuli, such as snakes and spiders, and non-fear-relevant stimuli. The current research examined whether… Expand
