Relationship between Self-Esteem and Self-Consciousness in Adolescents: An Eye-Tracking Study
Article information
Abstract
Objective
Self-esteem and self-consciousness are important determinants of behaviors. This study aimed to explore the relationship between self-esteem and self-consciousness in adolescents using the eye-tracking measurement.
Methods
Fifty-five adolescents with high self-esteem and 58 adolescents with low self-esteem participated in self-consciousness-related eye-tracking experiments of selecting happy, disgusted, and angry facial emotions while recognizing one’s own usual expressions and the others’ usual expressions toward oneself.
Results
When recognizing one’s own, adolescents with high self-esteem showed significantly more selection counts and longer fixation time for ‘happy’ than adolescents with low self-esteem. When recognizing the others’, adolescents with low self-esteem showed significantly more selection counts and longer fixation time for ‘disgusted’ and ‘angry’ than adolescents with high self-esteem.
Conclusion
These suggest higher self-esteem is connected to more positive identification of one’s usual expressions and others’ usual expressions toward oneself. There is a close relationship among low self-esteem, suppressing positive emotions, decreased psychological adjustment, and increased negative emotions.
INTRODUCTION
Adolescence is a transition period accompanied by physical, psychological, and social changes that cause emotional awakening, and thus it is a time when emotion regulation is the most challenging [1,2]. Emotional experience in this period is stronger than in any time in life. Emotional control at this time is related to social and emotional development, academic achievement, attention-concentration, prosocial behavior, problem-solving ability, interpersonal quality, and physical health [3], and its problem is linked to maladaptive behaviors and maladjustment [4].
Emotion is one of determinants of self-esteem. In particular, the specificity of adolescents’ attachment to parents and peers plays an important role in forming teenagers’ self-esteem [5]. Adolescents with high self-esteem have positive feelings about their lives such as cheerfulness, vigor, sense of security, confidence in the future, and realistic expectation of self, whereas those with low self-esteem often feel emotionally depressed [6]. Self-esteem is crucial to individuals’ psychological well-being, and the level of self-esteem can affect individuals’ sense of happiness in their lives [7].
It has been considered that self-esteem has a consistent influence on the identity styles [8]. Ideal self-esteem can be achieved through personal and subjective experiences, not by success in an external domain in which the eye of others is conscious [9]. In terms of social identity theory, an individual’s healthy self-concept derives from the harmonious perception of independent personal self and interdependent self [10]. Self-esteem is closely related to human relationships, and varies depending on how likely it is that one is rejected by another [11]. People with high self-esteem tend to make interpersonal relationships more pleasant by making cognitive beneficial interpretations even under negative circumstances, whereas those with low self-esteem are more likely to misinterpret events and to negatively affect the formation of interpersonal relationships [12].
Given that emotion provides crucial information about the significance of social situations [13], being aware of one’s own and others’ emotions is essential for adapting to a social environment. Emotion awareness is the ability to recognize and appreciate the importance of emotions in oneself and others [14], and involves a willingness to face one’s own and others’ emotions [15]. The ability to interpret and regulate one’s own emotions is an important factor in social adaptive behaviors [16]. The ability to accurately perceive and respond to others’ emotions including facial expressions is also crucial for social adaptation and interpersonal relationships [17,18]. Individuals with a clear perception of emotion tend to be more active in seeking social support and more satisfied with universal life [19,20]. On the contrary, those who lack emotion awareness show more internalization problems such as depression and somatization [21].
The relationship between emotion and self-esteem has been an interesting subject in the studies of the interpersonal relationships. For example, self-face evaluation and self-esteem show a closely interrelated relationship, which was mediated by the posterior cingulate cortex and ventral tegmental area [22]. In a previous study that examined eye movement to identify the effects of self-esteem on face recognition, individuals with high self-esteem paid more attention to self-face, whereas those with low self-esteem paid more attention to others [23]. In addition, it has been shown that emotion dysregulation mediates the association of low self-esteem level with physical aggression, anger, and hostility [24]. While most of these previous studies have focused on emotional recognition or regulation, the effects of self-esteem on self-consciousness have not been sufficiently studied yet.
Self-consciousness refers to the extent to which people direct attention inward or outward and is an important behavioral determinant of social interaction [25]. Previous studies have shown that negatively valenced appearance is related to increased self-consciousness [26,27]. The level of self-consciousness is closely related to satisfaction of the interpersonal relationship [28] and the relationship between perceived norms and addictive behavior [29]. Self-consciousness has been considered to have three prominent facets: private/public aspects, adaptive/maladaptive applied characteristics, and present/past experiences [30]. In particular, private self-consciousness is a tendency to introspect and examine one’s inner self and feelings, whereas public self-consciousness is an awareness of the self as it is viewed by others [25]. Facial expressions provide the most prominent clues about the emotional state of others, and people use facial expressions to adjust their behavior and determine their attitudes toward others [31]. Therefore, facial expressions can be a useful tool for the exploration of private and public selfconsciousness.
A purpose of this study was to investigate the relationship between self-esteem and self-consciousness in adolescents. Specifically, we examined a difference of eye-tracking movements in recognizing one’s own facial expressions and recognizing the others’ facial expressions toward oneself between the high and low self-esteem adolescent groups. In this study, our hypothesis was that the high self-esteem group would more positively identify their usual facial expressions and also more positively evaluate others’ facial expressions, compared to the low self-esteem group.
METHODS
Participants
The Korean version [32] of the Rosenberg self-esteem scale [33] was administered to 573 second-year students (16 years old; 209 males and 364 females) in two high schools in South Korea to screen out a total of 60 male and 60 female adolescents in the upper and lower percentiles of the self-esteem scores. The scores ranged from 35 to 40 points (referred to as “High SE group”) and from 17 to 28 points (referred to as “Low SE group”), respectively, and corresponded to the upper and lower 13th percentiles in male adolescents and 8th percentiles in female adolescents. They were subjected to a behavioral experiment and the assessment of additional questionnaires. After excluding those with eyesight problems and with missing responses, a total of 55 male adolescents (27 in High SE group, 28 in Low SE group) and 58 female adolescents (28 in High SE group, 30 in Low SE group) were included in the analysis. This study has been approved by the local Institutional Review Board Committee (3-2014-0257), and all participants signed a written informed consent.
Psychological assessments
The Beck Depression Inventory (BDI) [34], the Satisfaction with Life Scale (SWLS) [35], and Basic Psychological Needs Scale (BPNS) [36] were assessed to examine the level of depression, life satisfaction, and self-determination (autonomy, competence, and relatedness), respectively. The NEO Personality Inventory (NEO-PI-R) [37] was applied to evaluate five personality traits (extroversion, agreeableness, openness, neuroticism, Conscientiousness). Meanwhile, to confirm that there is no group difference in the level of intelligence, the Raven’s Progressive Matrices (RPM) [38] was assessed.
Behavioral tasks
We developed a self-consciousness task for eye-movement tracking, in which an experimental stimulus of each trial was comprised of 6 strangers’ faces (Figure 1). The faces were those of happy male, disgusted male, angry male, happy female, disgusted female, and angry female, which were placed in a hexagonal position. They were presented for 5 seconds, and then replaced with boxes in the same position. The boxes were presented for 2 seconds for participants to respond using a corresponding button in the keyboard following the instruction. A fixation cross was followed for the stimulus interval of 0.5 seconds. There are two experiments according to the instructions, which were “Choose which picture resembles the most closely your usual facial expression” in the experiment 1 and “Choose which picture resembles the most closely others’ usual facial expression toward you” in the experiment 2. Participants’ task was to select one of the faces by pressing the corresponding button. An experiment consisted of twenty trials of 7.5 seconds, taking a total of 150 seconds. The position of the faces was randomly arranged in the series of trials. The face stimuli used in the task were selected from the Korean Facial Expressions of Emotion [39].
Behavioral task procedure.
Eye movement recording
While participants performed the tasks, eye movements were recorded using the SensoMotoric Instrument (SMI, Boston, USA) eye movement monitoring system. Participants’ eye position was maintained at a distance of approximately 50 cm from the monitor. Before the experiment, participants were instructed to fix their gaze at several dots to calibrate their eye movements. The sampling rate of eye gaze during the measurement was 120 Hz. The gaze data were analyzed with SMI BeGaze. A fixation was counted when participants gazed at the monitor within an area of 100 pixels for more than 80 ms. The area of interest (AOI) was defined as a box drawn around the stimulus face. The rate of fixation in the AOI was calculated for each subject and stimulus. Among 6 AOIs, data from the male and female faces with the same emotion were averaged, and thus the fixation time was counted for AOIs with 3 emotions, such as ‘happy’, ‘disgusted’, and ‘angry’.
Statistical analysis
Demographic data and scale scores were compared between the two groups using independent-sample t-tests, except for sex, which was analyzed using chi-square test. The selection count and fixation time in each experiment were analyzed with a linear mixed model to identify the main effects and interactions of group and facial emotion. Associations of the fixation time with the selection counts and scale scores in each group were examined with Pearson correlation analysis. Considering that there were three facial emotions in all analyses, a significance threshold was defined at p<0.017 (0.05/3).
RESULTS
Psychological assessments
As shown in Table 1, the RSES scores were 38.02±1.78 in the high SE group and 23.84±2.71 in the low SE group, and were significantly different between the two groups (p<0.001). All participants have the same age, and the two groups showed no difference in gender distribution and cognitive ability measured by the RPM. The BDI scores were significantly lower in the high SE group than in the low SE group (p<0.001). The high SE group showed significantly higher scores in satisfaction with life, autonomy, competence, and relatedness than the low SE group (all: p<0.001). In the NEO-PI-R, the high SE group showed significantly higher scores in extroversion (p<0.001), agreeableness (p=0.001), conscientiousness (p<0.001), and openness (p<0.001), but significantly lower in neuroticism (p<0.001) than the low SE group.
Characteristics of participants
Task performance
The results of selection counts are shown in Table 2. The results were very similar between Experiment 1 and 2. In both experiments, most of the high SE group seldom chose ‘disgusted’ or ‘angry’, whereas a sizable number of the low SE group chose ‘disgusted’ and ‘angry’. The selection counts showed the main effect of emotion (Experiment 1: F2,11=528.18, p<0.0001; Experiment 2: F2,11=590.96, p<0.0001), but there was no main effect of group. Post-hoc test showed that the selection counts were significantly higher for ‘happy’ than for ‘disgusted’ and ‘angry’ (all: p<0.0001), but there was no difference between ‘disgusted’ and ‘angry’. The interaction effect of group x emotion was significant (Experiment 1: F2,111=15.46, p<0.0001; Experiment 2: F2,111=12.42, p<0.0001). Post-hoc test showed that the selection counts of ‘happy’ were significantly higher in the high SE group than in the low SE group, whereas those of ‘disgusted’ and ‘angry’ were significantly higher in the low SE group than in the high SE group (all: p<0.0001).

Eye-tracking data
Experiment 1 (Figure 2A): when selecting the face that the most closely resembled one’s own usual facial expressions, the fixation time showed the main effect of facial emotion (F2,11=126.94, p<0.0001), but no main effect of group. In the post-hoc test, the fixation time was significantly shorter for ‘disgusted’ (p<0.0001) and ‘angry’ (p<0.0001) than ‘happy’. The interaction effect of group x facial emotion was significant (F2,111=10.77, p<0.0001). The fixation time for ‘happy’ was not significantly different between the two groups, but those for ‘disgusted’ and ‘angry’ were significantly longer in the low SE group than in the high SE group (p=0.019 and 0.004, respectively).

Experiment 2 (Figure 2B): when selecting the face that the most closely resembled others’ facial expressions toward oneself, the fixation time showed the main effect of facial emotion (F2,11=151.47, p<0.0001), but no main effect of group. In the post-hoc test, the fixation time was significantly shorter for ‘disgusted’ (p<0.0001) and ‘angry’ (p<0.0001) than ‘happy’. The interaction effect of group x facial emotion was significant (F2,111=15.52, p<0.0001). The fixation time for ‘happy’ was significantly shorter in the low SE group than in the high SE group (p<0.0001), but those of ‘disgusted’ and ‘angry’ were not significantly different between the two groups.
Correlations between the selection count and fixation time (Table 3)
Correlations of the fixation time with the behavioral responses and scale scores
Experiment 1: the fixation time and selection count showed no correlation for all facial emotions in the high SE group, but they showed a positive correlation for ‘happy’ (r=0.54, p<0.001) and ‘disgusted’ (r=0.38, p<0.01) in the low SE group.
Experiment 2: in the high SE group, the fixation time and selection count showed a positive correlation for ‘angry’ (r=0.33, p=0.014), but no correlation for ‘happy’ and ‘disgusted’. In the low SE group, they showed a positive correlation for ‘happy’ (r=0.39, p<0.01), but no correlation for ‘disgusted’ and ‘angry’.
Correlations between the psychological scale score and fixation time (Table 3)
Experiment 1: in the high SE group, the significant results were the negative correlations between the autonomy scores and fixation time for ‘disgusted’ (r=-0.39, p<0.01) and ‘angry’ (r=-0.38, p<0.01), and between the relationship scores and fixation time for ‘disgusted’ (r=-0.37, p<0.01) and ‘angry’ (r=-0.39, p<0.01). In the low SE group, the only significant result was the negative correlation between the BDI scores and fixation time for ‘happy’ (r=-0.40, p<0.01).
Experiment 2: in the high SE group, the positive correlation was found only between the openness score and fixation time for ‘happy’ (r=0.33, r=0.015), whereas the negative correlations were found between the competence score and fixation time for ‘disgusted’ (r=-0.48, p<0.001) and ‘angry’ (r=-0.51, p<0.001). In the low SE group, there was no significant correlation between the scale score and fixation time.
DISCUSSION
In this study the relationship between self-esteem and selfconsciousness was investigated in adolescents using the two separate experiments of recognizing one’s own facial expressions and the others’ facial expressions toward oneself. The selection counts in both experiments were very similar. Although a difference of the fixation time between the high and low SE groups was significant only for ‘disgusted’ and ‘angry’ when recognizing one’s own facial expressions and only for ‘happy’ when recognizing the others’ facial expressions toward oneself, the overall patterns of the fixation time in both experiments were also similar. Therefore, it seems that the effects of self-esteem on self-consciousness have a similarity between the private and public ones.
In the selection counts, most of the high SE group chose ‘happy’, suggesting that adolescents who have high self-esteem tend to pay attention to positive emotions much more than negative emotions. This feature was confirmed in the fixation time, which was far longer for ‘happy’ than for ‘disgusted’ and ‘angry’, suggesting that an adolescent with high self-esteem may look at himself or herself desirable. These results are consistent with previous findings that individuals with high selfesteem had more stability as well as positive emotions and lower emotional changes than those with low self-esteem [40]. Selfesteem theory has predicted that the higher an individual’s self-evaluation, the less reciprocation of evaluations from others [41]. In particular, this group showed that the fixation time for ‘disgusted’ and ‘angry’ were negatively correlated with the autonomy and relatedness scores in Experiment 1 and the competence scores in Experiment 2, suggesting that the more self-determination of an individual may be linked to the less negative view of himself or herself. These correlations may be consistent with the argument that a person who is satisfied with autonomy, competence, and relatedness grows pro-social tendency [42]. Meanwhile, the selection count and fixation time for ‘happy’ were significantly correlated in the low SE group, but not in the high SE group. This group difference may be attributed to the ceiling effect of these responses to happy emotion in the high SE group.
In the selection counts, a sizable number of the low SE group chose ‘disgusted’ and ‘angry’ rather than ‘happy’. These features were confirmed in the eye-tracking measurement, which showed that the fixation times for ‘disgusted’ and ‘angry’ were significantly longer in the low SE group than in the high SE group. These results suggest that adolescents with low self-esteem tend to negatively recognize their own facial expressions and the others’ facial expressions toward themselves. It has been demonstrated that lower self-esteem is correlated with more negative emotions and higher public self-consciousness [43]. Relationships between suppression of positive emotions and selfesteem adjustment are mediated by a negative affect [44]. The underlying discrepant state of self-consciousness may contribute to their increased negative affect in the low SE group. It should be considered, for example, that self-awareness tasks increased negative affect among participants with low explicit and high implicit self-esteem [45].
Furthermore, in the low SE group, the fixation time for ‘happy’ was inversely correlated with the depression score. Low self-esteem in adolescence has been considered to be a predictor of the development of depression in early adulthood [46]. Recent longitudinal studies have also demonstrated that sustained or worsening disordered behaviors and low self-esteem in adolescents are precursors of depressive symptoms [47,48]. It should be noted that depression in adolescence has been associated with negative attributional style, limited interpersonal relationships, increased likelihood of social isolation, and overall maladjustment as well as low self-esteem [49-51]. In addition, lower self-esteem and negative emotions in adolescents sequentially mediate the relationship between body dissatisfaction and disordered eating [52]. Taken together, there is a close relationship among low self-esteem, suppressing positive emotions, decreased psychological adjustment, and increased negative emotions. Given this relationship, it is important to identify adolescents at risk for depression. Our self-conscious task may be useful to screen them in need of early interventions.
The low SE group showed significant differences in all basic psychological needs components and personality domains compared with the high SE group. However, basic psychological needs components were inversely correlated with the fixation time for negative emotions in the high SE group, whereas there were no correlations between the personality types and fixation time in both groups. These results suggest that selfconscious behaviors are related to basic psychological needs rather than personality types. According to the self-determination theory, positive emotion is merely a by-product of need satisfaction and all forms of mental health are ultimately supported by psychological need satisfaction [53]. The satisfaction of typical basic psychological needs is also crucial for experiencing wellbeing and esteem for one’s community [54].
This study had a few limitations despite the meaningful results above. First, academic achievement is an important factor for investigating self-esteem in high school students [55]. Because all participants were school students, they may have been gravely impacted by academic achievement; however, this parameter was not included in the analysis. Second, although the levels of self-esteem can differ between male and female adolescents [56], this difference was not analyzed because it was not a focus in this study. Third, all participants were second-year students in Korean high schools. An age variation in adolescence and a cultural difference in cognitive self-evaluations [57] could not be analyzed in this study.
In summary, we studied the relationship between self-esteem and self-consciousness in adolescents using eye-tracking measures for one’s own facial expressions and the others’ facial expressions toward oneself, and found that higher self-esteem was connected to more positive identification of their usual facial expressions and others’ facial expressions. Furthermore, the fixation time for ‘happy’ was inversely correlated with the depression score in adolescents with low self-esteem, suggesting that low self-esteem is associated with depressive behaviors in adolescence. Given that low self-esteem in adolescence are precursors of depressive symptoms, our self-conscious task may be used to identify adolescents at risk for depression and in need of appropriate interventions. Forwards, many types of research are needed to be done on emotional identification on self to know how to promote and maintain selfesteem in adolescents, which is the ultimate aim.
