Retarded disengagement from pain cues: the effects of pain catastrophizing and pain expectancy.

摘要: This paper reports an experimental investigation of engagement with and disengagement from a threatening cue pain. As most paradigms in pain research only provide overall index attentional deployment by pain-related information, new paradigm was developed that allowed independent cues. Forty pain-free volunteers performed cueing task which they had to detect targets tone as quickly accurately possible. The target stimuli were preceded cues (the word 'pain'), 'tone'), or neutral (a series the character 'X') at stimulus onset asynchrony (SOA: interval between onset) levels 100, 500, 900 ms. There no contingency type target. Catastrophic thinking about predictive value assessed self-reports. Results can be summarized follows: When correctly primed target, attention optimally engaged identification irrespective context However, when cued did not occur, there retardation cue. more pronounced extended across time those high catastrophic On examination it appeared may operate protection belief for is valid one, despite experience contrary.
