Abstract The present study examined the influence of enhancing performance expectancies through

16

comparative feedback on the learning of a sport motor skill, the basketball free throw, in

17

children. Two groups of participants, a positive comparative feedback group (PF) and a

18

control group, practiced 40 basketball free throws. All children received feedback regarding

19

their punctuation scores after each block of practice. Participants in the PF group also

20

received positive social-comparative feedback suggesting that their own punctuation score

21

was better than that of a peer group’s on the block. Learning effects were observed through

22

a transfer test performed one day after practice. Participants in the PF group demonstrated

23

higher learning of the task, showing greater punctuation scores on the transfer test than

24

participants in the control group. Questionnaire results also showed higher levels of

25

perceived competence, importance of doing well, and persistence related to the task among

26

the PF group relative to the control participants. These findings provide the first evidence

27

that enhancing performance expectancies through positive comparative feedback enhances

28

the learning of sport motor skills in children. They also demonstrate the important

29

motivational role of feedback on children’s learning of motor skills.

In recent years, a growing number of studies have been conducted to verify the effects of motivational factors on the learning of motor skills. For instance, studies have

36

provided evidence that the provision of autonomy (Carter, Carlsen, & Ste-Marie, 2014;

37

Chiviacowsky & Wulf, 2002; Fairbrother, Laughlin, & Nguyen, 2012; Lewthwaite,

38

Chiviacowsky, Drews, & Wulf, 2015; Wu & Magill, 2011; Wulf & Toole, 1999),

39

relatedness (Gonzalez & Chiviacowsky, 2016), and competence (Chiviacowsky & Wulf,

40

2007; Clark & Ste-Marie, 2007; Trempe, Sabourin, & Proteau, 2012; Lewthwaite & Wulf,

41

2010) support for learners during practice has a direct and positive impact on motor

42

learning. Autonomy, relatedness, and competence are considered basic psychological needs

43

and important sources of human motivation (Deci & Ryan, 2000, 2008). In the present

44

study, we examined whether enhancing children’s perceived competence or expectancies

45

for successful performance, through positive comparative feedback, would facilitate the

46

learning of a sport motor skill.

Competence implies the need to feel oneself as confident, rather than feeling

48

incapable, of skillfully mastering challenges in one’s environment (Ryan, 1995). It has long

49

been argued that individual’s performance, choice, effort, and persistence can be explained

50

by their efficacy expectancies or beliefs about how well they will do on a determined task

51

or activity (Bandura, 1982; Deci & Ryan, 2000, 2008; Wigfield & Eccles, 1992). In the

52

OPTIMAL theory of motor learning (Wulf & Lewthwaite, 2016), enhancing learners’

53

expectancies for future performance is also considered an important motivational factor.

Augmented feedback is considered as information provided by an agent (e.g.,

55

teacher, coach) related to aspects of one’s understanding or performance (Hattie &

56

Timperley, 2007) and one of the most powerful factors affecting motor learning (Schmidt,

ACCEPTED MANUSCRIPT 4 & Lee, 2011). Several studies have demonstrated a strong relationship between augmented

58

feedback, competence, and motor learning. For example, learners usually prefer to receive

59

feedback after good rather than poor trials (Chiviacowsky & Wulf, 2002, 2005; Fairbrother

60

et al., 2012; Grand et al., 2015; Patterson & Carter, 2010; Patterson, Carter & Sanli, 2011).

61

Feedback deliberately provided after good trials (Badami, Vaezmousavi, Wulf, &

62

Namazizadeh, 2012; Chiviacowsky & Wulf, 2007; Clark & Ste-Marie, 2007; Ste-Marie,

63

Vertes, Rymal, & Martini, 2011) or indicating successful performance through the

64

establishment of relatively easy criteria of good performance (Chiviacowsky & Harter,

65

2015; Chiviacowsky, Wulf & Lewthwaite, 2012; Palmer, Chiviacowsky & Wulf, 2016;

66

Trempe, Sabourin, & Proteau, 2012) has been demonstrated to enhance motor learning.

67

Likewise, feedback statements designating performance a result of malleable rather than

68

fixed capacities positively affects performance and learning of motor skills (Chiviacowsky

69

& Drews, 2014).

A related line of research supporting this “feedback/competence/learning”

71

relationship involves individuals’ competence evaluation amid social or temporal

72

comparison. For instance, participants who received general feedback informing them that

73

their performance had gradually improved across blocks of practice showed higher learning

74

and motivation relative to participants who were informed that their performance had

75

slightly degraded over time (Chiviacowsky & Drews, 2016). Similar effects on motor

76

learning were found in individuals receiving social-comparative feedback during practice,

77

where their outcomes were compared with those of others (Lewthwaite & Wulf, 2010;

78

Navaee et al., 2016; Pascua, Wulf, & Lewthwaite, 2015; Wulf, Chiviacowsky, & Cardozo,

79

2014; Wulf, Chiviacowsky, & Lewthwaite, 2010, 2012).

To date, however, only one experiment has observed the effects of enhancing learners’ expectancies through positive comparative feedback on motor learning in typical

82

children (Ávila, Chiviacowsky, Wulf, & Lewthwaite, 2012). Motivation after practice was

83

higher and the retention of a simple beanbag-throwing task was facilitated in 10-year-old

84

participants receiving positive social-comparative feedback relative to a control group.

85

Nevertheless, it is still largely unknown if this factor would facilitate the learning of more

86

complex motor skills, such as most of the sport skills. The objective of the present

87

experiment was, therefore, to observe the influence of positive social-comparative feedback

88

on the learning of a sport motor skill. Considering that there is a dearth of research on sport

89

skills learning in children, and the acquisition of new skills is considered to be significantly

90

more effective up until early adolescence than later in life (Janacsek, Fiser, & Nemeth,

91

2012), the potential benefits of positive comparative feedback on the acquisition of sport

92

skills in children were therefore deemed an important driver of this research.

Two groups of 10-year-old children were asked to practice the free-throw basketball task. Similar to the study of Ávila et al. (2012), the positive feedback (PF) group received

95

socio-comparative information after each given block of trials in addition to veridical

96

feedback suggesting that their average performance was better than that of a peer group’s

97

on that block. Participants in the control group received veridical feedback but were not

98

provided with social-comparative feedback. The learning of sport skills usually involves

99

task transfer (Schmidt & Lee, 2011) from simple or easy conditions of practice to more

EP

94

100

difficult or complex environments, normally involving well-established rules of

101

competition. Thus, in order to examine skill-learning effects as a function of positive

102

feedback, a transfer test was performed one day later. A customized questionnaire to assess

ACCEPTED MANUSCRIPT 6 the potential influence on participants’ level of perceived competence, enjoyment,

104

importance of doing well, and persistence related to the task as a function of practice

105

condition was applied at the end of practice. We hypothesized that the positive comparative

106

feedback group would demonstrate higher learning of the task than the control group. We

107

also expected that these participants would report higher levels of enjoyment, satisfaction

108

with performance, importance of doing well, and perhaps greater persistence related to the

109

task after practice, relative to participants in the control group.

The task involved the basketball free throw. A private gymnasium with a basketball

123

court was used for data collection. The free throw line for practice was located at a distance

124

of 3 m from the backboard, which was at a height of 2.60 m from the floor, and an official

125

youth ball (number 5) was used. Scores were established in relation to shot accuracy:

ACCEPTED MANUSCRIPT 7 specifically, 4 points for a converted ball, 3 points for balls that touched both the backboard

127

and the hoop; 2 points for balls that touched only the hoop; 1 point for balls that touched

128

only the backboard; and 0 points for missed shots.

RI PT

126

After completing the consent form, all participants were randomly assigned to the PF group and control group, with an equal number of males and females (9 boys and 4

132

girls) in each group, and introduced to the task. Data were collected individually and one of

133

the researchers for the present study was responsible for instructing all children.

134

Participants were informed about the goal of the task and observed two demonstrations of

135

how to perform it. They were instructed to throw the basketball overhand with both hands,

136

keeping their feet behind a line on the floor. The participants were also informed about the

137

punctuation score system and that they would receive feedback after each block of 10 trials

138

in relation to the sum of points in the specific block. Participants in the PF group were

139

informed that they would also receive comparative feedback on their performance in

140

relation to the performance of another group of children of the same age. More specifically,

141

these participants were informed about (false) peer’s average scores in the block, which

142

were always calculated as 20% less than the participants’ own scores. Thus, participants in

143

the PF group received veridical feedback and (false) positive social-comparative feedback

144

after each block of practice, while the control group received only veridical feedback after

145

each block.

The practice phase consisted of 40 trials, and one day later a transfer test was

performed, consisting of 10 trials without any augmented feedback. In this transfer test, the

148

free throw line was located at a distance of 4 m from the backboard, according to Mini

ACCEPTED MANUSCRIPT 8 Basketball official rules. In order to assess the subjective experience related to the task,

150

after the practice phase, all children filled out a customized questionnaire. For each of the

151

four statements (enjoyment, competence, importance and persistence-related), there were

152

four possible responses, ranging for example from “not competent/not important” to “very

Discussion

The present experiment was designed to examine whether enhancing performance

191

expectancies through positive social-comparative feedback, suggesting that participants’

192

performance was generally higher than the performance of peers, would enhance the

193

learning of the basketball free throw in children. The findings confirm our hypothesis,

194

showing that the group receiving positive comparative feedback demonstrated higher

ACCEPTED MANUSCRIPT 10 learning of the basketball free throw, measured in the transfer test, than the control

196

participants. Thus, in line with previous studies that manipulated participants’ competence

197

evaluation through social (e.g., Ávila et al., 2012; Lewthwaite & Wulf, 2010; Navaee et al.,

198

2016; Wulf et al., 2010, 2012;) or temporal-comparative feedback (Chiviacowsky &

199

Drews, 2016), providing children with general positive feedback, implying that their

200

performance was slightly higher than the performance of peers, led to more effective

201

learning of a sport skill than not giving them such information. The PF group also reported

202

higher perceived competence, importance of doing well, and persistence in practicing the

203

task at the end of practice compared with participants in the control group.

195

How can the observed effects be explained? The feeling of improving and

205

demonstrating one’s abilities or competence is considered fundamentally satisfying and

206

motivating (Deci & Ryan, 2000; White, 1959). Confidence can affect performance

207

expectancies, preparing individuals for further positive experiences, and impacting

208

cognitive, emotional and motor preparatory activity (Schmidt, Braun, Wager, & Shohamy,

209

2014; Schunk, 1991; Wigfield & Eccles, 1992; Wulf et al., 2012). According to the

210

OPTIMAL theory of motor learning (Wulf & Lewthwaite, 2016), enhanced expectancies

211

for performance are considered to strengthen the coupling of goals to actions, readying the

212

motor system for task execution and helping to consolidate memories. Performance

213

expectancies can also influence effort tolerance (Hutchinson, Sherman, Martinovic, &

214

Tenenbaum, 2008), positive affect (Stoate, Wulf, & Lewthwaite, 2012), importance of

215

doing well, and persistence in practicing the task (present study).

216 217

AC C

EP

TE D

204

Furthermore, enhanced expectancies may help learners to set higher performance goals (Bandura, 1997; Bandura & Locke, 2003; Locke & Latham, 2006), potentially

ACCEPTED MANUSCRIPT 11 affecting effort and attention paid during performance and resulting in performance gains

219

(Bandura & Jourden, 1991; West, Dark-Freudeman, & Bagwell, 2009; West & Thorn,

220

2001; West, Welch, & Thorn, 2001). In fact, greater self-efficacy has indeed been directly

221

associated with increased task-relevant attentional control during practice (Themanson &

222

Rosen, 2015), and observed to be a predictor of motor performance (for a review, see

223

Moritz, Feltz, Fahrbach, & Mack, 2000) as well as learning (Chiviacowsky, 2014;

224

Chiviacowsky et al., 2012; Stevens et al., 2012; Wulf et al., 2014). Less confident learners,

225

however, tend to occupy themselves with counterproductive self-evaluative concerns,

226

decreasing effort and attention or explicit monitoring activity to important aspects of the

227

task, whereby degrading performance (Bandura, 1982; Bandura & Wood, 1989; Sarason,

228

1984; Wine, 1971) and motor learning (Cardozo & Chiviacowsky, 2015; Heidrich &

229

Chiviacowsky, 2015; McKay, Wulf, Lewthwaite, & Nordin, 2015).

218

In conclusion, the findings provide the first evidence that enhancing learners’

231

performance expectancies through positive comparative feedback facilitates the learning of

232

sport motor skills in children. They also emphasize the important motivational role of

233

augmented feedback in motor learning. Future studies may reveal further comparative

234

feedback effects on the learning of different kinds of sport skills in various populations.

235

Considering practical applications, it is suggested that professionals involved with

236

teaching-learning processes take advantage of enhancing expectancies strategies, for

237

example highlighting positive aspects of performance, or facilitating success experience, in

238

order to benefit sport skills learning.
