简要总结

Research has shown that mental imagery appears to carry emotion better than verbal communication. One way this can be noted is that emotional mental imagery trigger physiological arousal responses. These may be important for treatment techniques using mental imagery, such as imaginal exposure and imagery re-scripting. However, as the development of clinical applications increasingly considers the use of flashpoint imagery, i.e. mental imagery of short duration, it is of interest to examine whether also flashpoint imagery trigger arousal responses. This study examines the arousal response to flashpoint imagery of different valence (positive, negative, and neutral).

Moreover, emerging evidence suggest that depressed individuals find it more difficult to produce mental imagery of positive future events (less accessible and vivid) than healthy controls. In addition, individuals with clinical anxiety appear to be able to produce imagery of negative future events more easily than healthy controls. This study explores whether these results can be noted also in sub-clinical symptoms of depression and anxiety, and if so, if they are accompanied with corresponding changes in arousal responses.

详细描述

This study takes part in a single session. Participants will produce flashpoint imagery of future events while skin conductance responses, imagery vividness ratings, valence and arousal ratings are collected. Participants will also fill in questionnaires on depression and anxiety symptoms, as well as a questionnaire measuring general propensity for mental imagery.

结局指标

主要结局

Skin conductance response (SCR)

时间窗: Day 1

SCR is used to measure physiological arousal response to the mental imagery production. The study evaluates differences in SCR between valences of prospective imagery (neutral, negative, positive) and possible covariation with self-rated anxiety or depression symptoms.

Imagery vividness ratings

时间窗: Day 1

Scale: 1-5; no image at all - image as clear and vivd as real life

次要结局

  • Subjective Valence Ratings(Day 1)
  • The Vividness of Visual Imagery Questionnaire(Day 1)
  • Time in seconds it takes to construct a situation to visualize(Day 1)
  • Subjective Arousal Ratings(Day 1)
  • State-Trait Anxiety Inventory(Day 1)
  • Formulär för patienthälsa (PHQ-9)(Day 1)
