Gratitude Affects Inter-Subjective Synchronicity for Cognitive Performance and Autonomic Responsiveness

Figures

  Figure 1. Experimental procedure. Two different procedures were performed: order 1 composed by block 1 (a control condition), gift exchange, and blocks 2 and 3; and order 2 composed by block 1, block 2, gift exchange, and block 3. Blocks 1, 2, and 3 involve a cooperative task which consisted of a game of selective attention.

  Figure 2. (A) Increase in accuracy for order 1 in blocks 2 and 3 more than block 1 and in block 3 more than block 2. For order 2, instead, the figure shows an increase of accuracy in block 3 more than blocks 1 and 2. (B) Increase of inter-subjective accuracy (r values) for order 1 more than order 2 in block 2 and block 3. Moreover, for order 1, the figure shows an increase of inter-subjective accuracy (r values) in block 3 more than block 1. In addition, higher synchronicity was observed in order 1 for block 3 more than block 2.

  Figure 3. (A) Increase in individuals’ skin conductance level (SCL) for order 1 in block 2 and block 3 more than order 2. Moreover, the figure shows for order 1 an increase of SCL in blocks 2 and 3 more than block 1; while, for order 2, an increase of SCL in block 3 more than block 1. (B) For heart rate (HR), the figure shows an increase of HR for order 1 more than order 2 in block 2 and block 3. Specifically, for order 1, the figure shows an increase of HR in blocks 2 and 3 more than block 1.

  Figure 4. Increased HR subjects’ synchrony (r values) for order 1 more than order 2 in block 2 and block 3. Moreover, for order 1, the figure shows an increase in HR synchrony in blocks 2 and 3 more than block 1 and in order 2, an increase of HR subjects’ synchrony was found block 3 more than block 1.
