A recently developed fast MR imaging system is utilized for a study of emotional speech production. Speech utterances and corresponding mid-sagittal vocal tract images are simultaneously acquired by the MRI system. Neutral, angry, sad and happy emotions are simulated by a male American English speaker. The MRI system and analysis results are described in this report. In general articulation is ...

Although trait anxiety has been associated with risk decision making, whether it is related to risk per se or to the feeling of the risk, as well as the underlying neurocognitive mechanisms, remains unclear. Using a decision-making task with a manipulation of frame (i.e., written description of options as a potential gain or loss) and functional magnetic resonance imaging, we investigated the n...

The P1vital® Oxford Emotional Test Battery (ETB) comprises five computerized tasks designed to assess cognition and emotional processing in human participants. It has been used in between-subjects experimental designs; however, it is unclear whether the battery can be used in crossover designs. This is of particular importance given the increasing use of ETB tasks for repeated assessment of dep...

Research indicates that emotion can affect the ability to monitor and replace content in working memory, an executive function that is usually referred to as updating. However, it is less clear if the effects of emotion on updating vary with its relevance for the task and with age. Here, 25 younger (20-34 years of age) and 25 older adults (63-80 years of age) performed a 1-back and a 2-back tas...

BACKGROUND It is clearly established that emotional events tend to be remembered particularly vividly. The neurobiological substrates of this phenomenon are poorly understood. Recently, the noradrenergic system has been implicated in that beta blockade has been shown to reduce significantly the delayed recall of emotional material with matched neutral material being unaffected. METHODS In the...

Cannabis has long been known to produce cognitive and emotional effects. Research has shown that cannabinoid drugs produce these effects by driving the brain's endogenous cannabinoid system and that this system plays a modulatory role in many cognitive and emotional processes. This review focuses on the effects of endocannabinoid system modulation in animal models of cognition (learning and mem...

Background: The Big Five are seen as stable personality traits. This study hypothesized that their measurement via self-ratings is differentially biased by participants’ emotions. The relationship between habitual emotions and personality should be mirrored in a patterned influence of emotional states upon personality scores. Methods: We experimentally induced emotional states and compared base...

Traditional models of cognitive control have explained performance monitoring as a "cold" cognitive process, devoid of emotion. In contrast to this dominant view, a growing body of clinical and experimental research indicates that cognitive control and its neural substrates, in particular the error-related negativity (ERN), are moderated by affective and motivational factors, reflecting the ave...

Emotion can modulate pain and spinal nociception, and correlational data suggest that cognitive-emotional processes can facilitate wind-up-like phenomena (ie, temporal summation of pain). However, there have been no experimental studies that manipulated emotion to determine whether within-subject changes in emotion influence temporal summation of pain (TS-pain) and the nociceptive flexion refle...
