Effects of Pleasant or Unpleasant Feedback Messages on the Learning of Timing
Abstract: We investigated the effects of pleasurable and unpleasurable messages on the learning of timing using a ten-key pressing task. The messages affected the participants’ emotions and provided them with knowledge of the results (KR). A total of 42 university students participated in this experiment. They were divided into three groups: the pleasurable message group (PMG), the unpleasurable message group (UMG), and the control group (CG). Participants were required to 1) press “2”, “4”, “8”, and “6” in order on the ten-key pad, 2) finish within 1100 ms of pressing “2”, and 3) press with relative time intervals of 22.2%, 44.4%, and 33.3%. All groups were provided with the following KR after every practice trial: total time and relative time intervals. Participants in the PMG and UMG groups were provided with pleasurable or unpleasurable messages, respectively, if their total times were within ±5% of the range, or when any of their time intervals fell outside of ±10% of the range. Three pretest trials, 30 practice trials, and three posttest trials were performed on Day 1. Three retention trials and 3 transfer trials were performed on Day 2. The transfer trials total time was 1800 ms, and that of the relative time interval was the same as on Day 1. The results indicate that although all groups learned the timing task, the UMG had higher variable and root mean square errors on the transfer test compared to the PMG and CG. These results suggest that unpleasurable messages are disadvantageous for learning stable timing during the ten-key pressing task because unpleasurable emotions may negatively affect cognitive processing.

1. Introduction

The pleasurable or unpleasurable messages provided by teachers and coaches likely affect students’ or players’ emotions, motivation to complete activities, learning strategies, and memory for learned skills during physical education classes and sports activities. For example, it has been reported that emotion influences the type of information processing used in decision-making, expectations of the results, and past memories (Schwarz, 2000) . In addition, emotion and cognition are correlated with decision-making and motivation to complete activities of daily life (Izard, 2011) .

It is generally known that pleasurable emotions promote decision-making and problem-solving, as long as there is social activity and a thinking process, and the subject is interesting and important (Isen, 1999) . It has been reported that humiliation, insults, blame, and threats from elementary schoolteachers lead to unpleasurable emotions in children, while eulogies, praise, and encouragement lead to pleasurable emotions (Aliyev, Karakus, & Ulus, 2013) . Ithas also been reported that the supportive actions of junior high school teachers, such as those supporting a student’s strategies and encouraging social constructs that support students, improved the students’ motivational and management abilities (Wallace, Sung, & Williams, 2014) .

Sugawara, Tanaka, Okazaki, Watanabe, and Sasato (2012) examined the effects of praise on motor learning using a serial finger-tapping task. The results indicated that the group that was praised for their performance had significantly better performance than did either the group that watched other participants receive praise or the group that was not praised when the participants suddenly performed the learned serial finger-tapping movement. However, there were no significant differences among the three groups when the participants performed the task using a new serial random-order movement. They thus concluded that motor skill improvements due to praise are observed when praise is provided while the task is not being performed (off-line monitoring) rather than during the task (on-line monitoring).

Kris and Shalini (2012) reported that creativity-contingent rewards are effective if the participants are provided with pleasurable feedback accidentally while they are learning, and that this feedback leads to performance that is more creative. On the other hand, performance-contingent or completion-contingent rewards have slightly negative effects on creative performance. Hooyman, Wulf, and Lewhwaite (2014) examined the effects of three types of instruction using the cricket bowling action task: instruction supporting the participant’s independence during the learned behavior, instruction controlling the learned behavior, and in-between instruction. The results indicated that the selection rate is highest for instruction that supports the participant’s independence during the learned behavior, and that this type of instruction improved confidence, reduced the necessity of dealing with unpleasurable emotions, and had positive effects on kinesthetic memory in comparison to instruction controlling the learned behavior. These reports indicate that the pleasurable words of others, remuneration, and supportive social constructs positively affect the participant’s attitude, motivation, and efficacy during the task and greatly improve performance.

Unpleasurable emotions reportedly narrow the range of attention during cognitive tasks and decrease the thought-action repertoire (Frederickson & Branigan, 2005) . Ogawa, Masaki, Yamazaki, and Sommer (2001) have reported that participants who were verbally admonished had smaller decreases in their error- related negativity potentials and reduced performance monitoring compared to a control group. In other words, unpleasurable emotions are likely disadvantageous in terms of motor skill learning in comparison to pleasurable emotions. Based on these reports, we may assume that pleasurable emotions during motor learning facilitate learning compared to unpleasurable emotions. We thus examined the effects of pleasurable or unpleasurable messages on motor skill learning using a timing movement task.

2. Methods

2.1. Participants

The participants were 42 university students (25 men and 17 women) with a mean age of 20.1 years (standard deviation [SD] = 1.3 years). Each participant’s dominant hand was determined using the Chapman’s dominant hand test (Chapman & Chapman, 1987) . All participants were right-handed, and none had previously experienced the task.

This experiment was conducted after approval was obtained from the Doshisha University Ethics Committee for Scientific Research Involving Human Subjects.

2.2. Task and Apparatus

The task is illustrated in Figure 1. The participant was seated in front of a 19-in.

Figure 1. Timing movement task. All participants were required to press the keys as follows: 1) press 2, 4, 8, and 6 in order using the right index finger; 2) press the “6” key on the ten-key keyboard within 1,100 ms after initiating the sequence by pressing the “2” key; and 3) press the keys with relative time intervals of 22.2%, 44.4%, and 33.3% between the “2” key and the “4” key, the “4” key and the “8” key, and the “8” key and the “6” key, respectively.

monitor (Mitsubishi RDT195LM) that had been positioned on a desk. Each participant was required to press a ten-key pad on a computer keyboard using their right hand in the following order: 2, 4, 8, and 6. The goal was to complete these four sub-movements in 1100 ms, and to maintain relative time intervals of 22.2%, 44.4%, and 33.3% between the pressing of 2 and 4, 4 and 8, and 8 and 6, respectively.

2.3. Procedures

The participants provided written, informed consent and received\1000 cash as compensation for their cooperation. The experiment was conducted with each participant individually.

Figure 2 shows the experimental procedure. After the task and the procedure were explained, each participant performed a pretest consisting of three trials with no knowledge of results (KR).

The participants then performed a practice phase consisting of 30 trials. Each participant was assigned, by sex, to one of three groups: the pleasurable message group (PMG), the unpleasurable message group (UMG), and the control group (CG). Performance time was measured from the moment the “2” key was pressed to the moment the “6” key was pressed, and a relative time interval was calculated. All participants were provided with KR on the monitor after every trial, which consisted of their performance time and a related time interval. The PMG and UMG were provided with a pleasurable or unpleasurable message, respectively, if the participant’s total time was ±5% (from 1045 ms to 1155 ms) outside the range, or if one of the time intervals was outside ±10% of the range (“2” key - “4” key: from 12.2% to 32.2%, “4” key - “8” key: from 34.4% to 54.4%, “8” key - “6” key: from 23.3% to 43.3%).

Figure 2. Experimental procedure.

Table 1 shows the pleasurable and unpleasurable messages used in this experiment (Ishikura & Fujimoto, 2014) . These messages were provided by replaying audio files with voices from male and female university students who were actors in the university’s drama program.

A posttest consisting of three trials with no KR was conducted 15 seconds after the practice phase. A retention test consisting of three trials and a transfer test consisting of three trials were performed with no KR on the next day. During the transfer tests, although the participants were asked to press the same keys in the same order with the same relative time intervals as in the original task,

they were also asked to press the “6” key 1800 ms after pressing the “2” key. When a participant pressed the wrong key, it was considered to be an error. The participant then resumed the task by pressing the “2” key.

E-Prime 2.0 Professional (Psychology Software Tools Inc.) psychological experimental software was used to control the experimental protocol and to measure the movement times.

2.4. Dependent Variables

The time interval in ms between pressing the “2” key and pressing the “6” key was recorded. Data from the pretest, the posttest, the retention test, and the transfer test are summarized for the three trial blocks. Absolute error (AE) and variable error (VE)were used to evaluate performance in terms of total time, and root mean square error (RMSE) was used to evaluate performance in terms of relative time intervals. These measures of error were the dependent variables. To estimate the number of times the participants in the PMG and the UMG received messages regarding timing errors, the number of deviations from the time range during the practice phase was recorded.

2.5. Analysis

One-way analyses of variance (ANOVAs) were used to assess differences in the three variables (AE, VE, and RMSE) on the pretest and the numbers of messages received by participants in the PMG and the UMG during the practice phase. A three-way (3 [group: PMG, UMG, CG] × 2 [sex: male, female] × 3 [test: pretest, posttest, retention test]) repeated measures ANOVA was used to evaluate performance acquisition. A two-way (3 [group] × 2 [sex]) ANOVA was used to evaluate learning during the transfer test. All significant effects are reported using p < 0.05 as the significance level. Effect sizes are reported as η2, and statistical power is reported as ϕ. Post hoc comparisons of the means were performed using the Bonferroni technique. IBM SPSS Statistics Version 24 (IBM, Inc.) statistical software was used for all statistical analyses.

3. Results

Table 2 shows the means and standard deviations of AE, VE, and RMSE for each test. There were no significant differences among the three groups for AE, VE, and RMSE, as determined by a one-way ANOVA for pretest performance (see Table 2).

3.1. Acquisition

AE, VE, and RMSE for the three groups were computed. A significant effect of Test was observed for AE (F2,72 = 13.80, p = 0.01, η2 = 0.28, ϕ = 1.00), VE (F2,72 = 8.55, p = 0.01, η2 = 0.19, ϕ = 0.96), and RMSE (F2,72 = 15.49, p = 0.01, η2 = 0.30, ϕ = 1.00). Post hoc comparisons of AE, VE, and RMSE indicated that the pretest values were higher than the posttest and retention test values, and that there were no differences in the posttest and the retention test. There were no main

effects of group or sex, and there were no significant interactions between the variables.

3.2. Transfer Tests

AE, VE, and RMSE for the three groups were computed for the transfer test (see Table 2). There was a main effect of Group for VE (F2,36 = 4.65, p = 0.02, η2 = 0.21, ϕ = 0.75) and RMSE (F2,36 = 3.23, p = 0.05, η2 = 0.15, ϕ = 0.58). Post hoc comparisons of VE and RMSE indicated that the pretest values were higher than those of the posttest and the retention test, and that there were no differences in the posttest and the retention test. There was no significant main effect of sex, and there were no significant interactions for VE and RMSE. There were no significant effects of Group or Sex, nor any significant interactions for AE.

3.3. Numbers of Messages

There were no significant differences in the numbers of messages provided during the practice phase among the three groups. The mean of the number of messages provided was 28.7 (SD = 1.8).

4. Discussion

The values for the posttest and the retention test, which took place on the day after the original task was practiced, decreased less than those of the pretest. We thus observed learning of the timing movement. However, on the transfer test, which took place on Day 2, the UMG had larger VE and RMSE than the PMG and the CG. We may thus conclude that listening to unpleasurable messages may lead to unstable task performance retention.

Frederickson and Branigan (2005) reported that unpleasurable emotions lead to a narrowing of the scope of attention during cognitive tasks and decrease the thought-action repertoire. It has been reported that participants receiving verbal admonitions have decreased error-related negativity potentials and reduced per- formance compared to control group participants (Ogawa, Masaki, Yamazaki, & Sommer, 2011) . In the central nervous system, the striatum, which is a basal nucleus in the brain that may include the amygdala, participates in the formation of memories of kinetic system sequences. Since the basal nuclei of the brain accelerate purposeful movements and control unnecessary movements, movement control may be affected if the amygdala is stimulated.

Since we did not observe differences between the groups for the original task, we may conclude that the messages had no influence on learning. However, we clearly show that participants who heard unpleasurable messages during the transfer task were more unstable than those in other groups. Therefore, our results may indicate that listening to unpleasurable messages leads to unstable performance in the transfer task in comparison to listening to pleasurable messages or to not listening to a message at all. This may be because the selection of memory information, performance monitoring, and amygdala stimulation in the central nervous system influences cognitive processing, which is needed to appropriately transfer the kinesthetic memory of the learned original task.

Future studies would require examinations of the effects of emotion-evoking messages on the central nervous system using functional magnetic resonance imaging. In addition, since the timing movement task was used as a learning task in this study, future studies should focus on other movement-constituting elements. These include the role of space during the performance of movements (e.g., throwing darts) or the need to adjust the force of a movement. It would thus be necessary to consider the influence of pleasurable or unpleasurable messages on the learning of movement.
