Sentence examples for stimulus expectancy from inspiring English sources

Fear potentiated startle responses, skin conductance responses and unconditioned stimulus expectancy scores were measured throughout the experiment.

We extended the study of Raes, De Houwer, Verschuere, and De Raedt (2011) by controlling for context conditioning and recording unconditioned stimulus expectancy online in a within-subject design.

Functional magnetic resonance imaging scans obtained during an emotion face matching task (EFMT) and an affective stimulus expectancy task (STIMEX) were performed at baseline, one hour after initial drug administration and 28 days later.

Arousal response intensity increases if the stimulus expectancy has high affective value or if the response outcome expectancy is inadequate.

The results of the current PPI connectivity analysis suggest that the close coupling between the dopaminergic midbrain and the hippocampus is modulated by stimulus expectancy and is especially responsive to contextual novelty.

Also, our theta phase-coherence results revealed a coupling between the right TPJ and the left vmPFC, 2 areas that have been strongly associated with the mentalizing network and their direct functional coupling is harder to reconcile with a stimulus expectancy account than with a mentalizing account (see also Mars et al. 2012).

However, these signals may be also top-down modulated, at least to some extent, based on observers' stimulus expectancies [1], [8], [10].

The theoretical basis of CATS is the cognitive reformulations of learning theory [ 24, 26], where classical conditioning is regarded as acquisition of expectancies of the outcomes of stimuli (stimulus expectancies), and instrumental or operant conditioning as the acquisition of expectancies of the results of available responses (response outcome expectancies).

All of these models are brought together within the Cognitive Activation Theory of Stress (CATS) [ 5], which assumes that acquired response and stimulus expectancies determine the physiological and psychological responses, which in turn influence subjective health complaints such as pain through neurobiological sensitization [ 4, 5].

Here, we also describe in details the respective neural responses elicited by violations of local and global auditory regularities, and we report two additional ERP effects related to stimuli expectancy and to task learning, and we discuss their relations to consciousness.

Outcomes included indices of pain-related conditioning such as unconditioned stimulus (US) expectancy and contingency awareness, self-report and physiological measures of pain-related fear, evaluative judgements of conditioned stimulus pleasantness, and muscular and cortical responses.
