CBM training program variant 1
Attention training towards positive cues using words as stimuli
Cognitive bias modification training program variant 1
Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 1. Participant is exposed to two words -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (\< or \>) in the previous position of ONE of these words and is then asked to press the corresponding arrow button on a keyboard. A total of 192 word pairs are shown during a session, of one third is the neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe always follows the more positive word.
CBM training program variant 2
Attention training towards positive cues using words and faces as stimuli
Cognitive bias modification training program variant 2
Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 2. Participant is exposed to a pair of words or a pair of faces -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (\< or \>) in the previous position of ONE of these words or faces and is then asked to press the corresponding arrow button on a keyboard. A total of 96 word pairs and 96 face pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe always follows the more positive word or face.
CBM training program variant 3
Attention training towards negative using words as stimuli
CBM training program variant 3
Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 3. Participant is exposed to two words -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (\< or \>) in the previous position of ONE of these words and is then asked to press the corresponding arrow button on a keyboard. A total of 192 word pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe always follows the more negative word.
CBM training program variant 4
Attention training towards negative using words and faces
CBM training program variant 4
Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 4. Participant is exposed to a pair of words or a pair of faces -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (\< or \>) in the previous position of ONE of these words or faces and is then asked to press the corresponding arrow button on a keyboard. A total of 96 word pairs and 96 face pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe always follows the more negative word or face.
Control training variant 1
Control training condition using words as stimuli
Control training variant 1
Computerized, internet-based training program for implicit modification of cognitive bias of attention, variant 1. Participant is exposed to a pair of words -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (\< or \>) in the previous position of ONE of these words and is then asked to press the corresponding arrow button on a keyboard. A total of 192 word pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe follows the more positive word and the more negative word with equal frequency..
Control training variant 2
Control training condition using words and faces as stimuli
Control training variant 2
Computerized, internet-based control training program, variant 2. Participant is exposed to a pair of words or a pair of faces -- either neutral-negative, neutral-positive, or negative-positive -- for 500ms-1000ms, followed by a probe (\< or \>) in the previous position of ONE of these words or faces and is then asked to press the corresponding arrow button on a keyboard. A total of 96 word pairs and 96 face pairs are shown during a session. One third is neutral-negative, one third is neutral-positive, and one third is negative-positive. The probe follows the more positive stimulus and the more negative stimulus with equal frequency.
