Correlations Between Iq Scores And Academic Performance Psychology Essay

Anastasi noted declining correlations between IQ scores and academic performance with increasing levels of educational attainment. Specifically, the correlations between the two constructs declined from r = .70 in elementary school to r = .50 in secondary school and to r = .40 in college (Chamorro-Premuzic & Furnham, 2005). Within postsecondary education itself, there is a declining correlation between ability tests and other measures of intelligence with increasing years at school. This pattern repeats itself at the post-graduation level – abilities have the highest predictive validity at the commencement of a students’ university or postgraduate experience, and then subsequently decline in magnitude (Humphreys, 1968; Humphreys & Taber, 1973).

These results indicate that individual differences in academic performance due to cognitive ability disappear with increasing years of education, even after clearing successive hurdles to admission. Hence, it appears that non-ability factors (i.e., personality, self-efficacy, and motivational variables) become more important in distinguishing between better and worse students when the students are pre-selected by past academic performance or intellectual ability (Chamorro-Premuzic & Furnham, 2006a).

Recent studies provide evidence in support of the measures of personality dimensions as possible predictors of academic achievement (e.g., Duckworth & Seligman, 2005). Martin et al. (2006) found that personality characteristics have a major impact on performance at the undergraduate level across all 4 years of coursework. This impact was observed over and above the effects resulting from high school academic performance and intellectual ability (i.e., achievement test scores). Chamorro-Premuzic and Furnham (2003) studied the linkages between personality traits and academic performance using two longitudinal samples of British university students. They found that personality scores measured during the first week of the academic year were significantly related to final exam results and programme work that were assessed three years later. Further, the predictive power of personality traits accounted for another 10-17% variance in academic performance when it was related to both academic behaviours (like attendance and class involvement) and teacher’s predictions. In another study, Furnham et al. (2003) found that personality traits accounted for about one-fifth of variance in exam marks and one-third of variance in essay grades over a 2-year period.

McLaughlin, Moutray & Muldoon (2007) examined the impact of personality in predicting academic performance among nursing students. They administered the Eysenck’s personality questionnaire (EPQ-R) on 384 nursing students in their first year of study. The results of the EPQ-R were then analysed along with the final marks obtained at the end of the program. They found that students with high scores on psychoticism were more likely to withdraw from the program. Extraversion was also seen to negatively impact academic performance – those scoring high on extraversion were more likely to achieve lower marks. In another study, Bisping & Patron (2008) also found personality type as a significant determinant in academic success. They used the MBTI to study the impact of personality type in an introductory general business course designed to incorporate knowledge from various business disciplines.

Caspi, Roberts, and Shiner (2005) argued for a causal relationship between personality traits and academic performance. They postulated that personality traits and academic performance might be causally related if achievement criteria and personality dimensions overlap. In other words, the causal relationship will arise when a certain behaviour indexing a certain personality trait is also a part of successful performance. For instance, exerting effort as a behaviour (relevant to conscientiousness) is likely to be important for securing high grades in school (Rothstein, Paunonen, Rush, & King, 1994), thereby indicating the existence of a causal relationship.

Given the wide variety of personality measures available and the subsequent difficulty of making generalisations across studies, there is considerable debate regarding which personality traits are associated with superior academic performance. Nevertheless, the majority of research examining the importance of personality in academic performance has used the Big Five Model of Personality (Costa & McCrae, 1992). For example, Tok and Morali (2009) examined the predictive ability of the Big Five personality factors on academic success for a total of 295 physical education (PE) teacher candidates. They found that academic success as GPA was positively related to Openness to Experience and Conscientiousness and negatively associated with Neuroticism. In a meta-anlysis by O’ Connor and Paunonen (2007), conscientiousness (r = .24), extraversion (r = -.05) and openness (r = .06) were identified as the most consistent predictors of academic achievement. In another study, Mervielde (1994) and Mervielde, Buyst, and De Fruyt (1995) examined teacher ratings of different age groups (from 4-12 years). They found that both Openness and Conscientiousness showed significant association with academic performance. Barbaranelli, Caprara, Rabasca, and Pastorelli (2003) also found these two traits as the most important personality correlates of academic success across different informants (self, teacher, and parent).

Each of the five factors – Conscientiousness, Openness to Experience, Agreeableness, Extraversion, and Neuroticism – have been discussed below with regards to their impact on academic performance.

Conscientiousness

Conscientiousness is associated with the will to achieve, self-control, determination, purposefulness, and dependability. Chamorro-Premuzic & Furnham (2004), and Moutafi, Furnham, & Crump (2003) report a negative relationship between IQ and conscientiousness. Nevertheless, it appears that conscientiousness, as a personality construct, most strongly correlates with academic achievement in both undergraduate and graduate settings (Busato, Prins, Elshout, & Hamaker, 2000; Chamorro- Premuzic & Furnham, 2003a, 2003b; Noftle & Robins, 2007).

Noftle and Robins (2007) used multiple personality inventories across four independent samples of more than 10,000 participants. They found conscientiousness to be the strongest predictor of both high school and college GPA. Chamorro-Premuzic, Furnham, and Ackerman (2006) found conscientiousness to be a good predictor of academic success (r = .19 to .31) on multiple measures including exams, continuous assessment (presentations), and written essays over a three year period. Lievens, Coetsier, De Fruyt and De Maeseneer (2002) found conscientiousness to be a significant predictor of academic performance among medical students in each of their three preclinical years. Further, successful students differed from the unsuccessful ones on the subconstructs of dutifulness, achievement orientation, and self-discipline.

Conscientiousness is associated with sustained efforts and goal setting activities (Barrick, Mount, & Strauss, 1993), both of which are said to contribute to scholastic achievement (Steel, 2007). It is also related to compliance and attention to home assignments (Trautwein, Ludtke, Schnyder, & Niggli, 2006), to time management and to regulation of effort in learning activities (Bidjerano &Dai, 2007). This attests the relationship of conscientiousness to academic performance, class attendance, and final grades (Conard, 2006). MacCann, Duckworth, & Roberts (2009) found that each facet of conscientiousness (e.g., diligence, dependability, self-discipline, prudence, competence, dutifulness, order, and achievement striving) contributed to higher performance in academic settings, attainment of scholastic success, and lower disciplinary infractions. The facets also independently predicted Grade Point Average (Chamorro-Premuzic &Furnham, 2003; Furnham et al., 2003; Martin et al., 2006), motivation (Komarraju & Karau, 2005), effective learning styles (Duff et al., 2004), and academic aspirations (Rottinghaus, Lindley, Green, & Borgen, 2002). Finally, Chamorro-Premuzic and Furnham (2004, 2006a) argue that in competitive settings, conscientiousness may play a compensatory role for lower cognitive ability and consequently promote higher academic achievement.

Thus, the conscientious person who works hard, completes tasks, and strives to succeed is more likely to be motivated to perform well. This would help him in achieving higher academic success (Furnham & Monsen, 2009).

Openness to Experience

Openness to Experience is characterised by receptiveness to new ideas, preference for varied sensations, attentiveness to inner feelings, and intellectual curiosity. Evidence supporting the relationship between Openness to Experience and scholastic success is mixed. Some studies report a positive relationship between Openness and academic performance (e.g., DeFruyt & Mervielde, 1996; Farsides & Woodfield, 2003; Hirschberg & Itkin, 1978; Lievens et al., 2002; Philips, Abraham, & Bond, 2003), effective learning style, and higher academic aspirations (Rottinghaus et al., 2002). However, other studies do not support such a relationship (e.g., Busato et al., 2000; Chamorro-Premuzic & Furnham, 2003b).

Openness has been positively related to final school grades and to strategies involving critical thinking (Bidjerano & Dai, 2007; Komarraju & Karau, 2005), and motivation to learn (Tempelaar, Gijselaers, Schim Van Der Loeff, & Nijhuis, 2007). Chamorro-Premuzic and Furnham (2003) found openness to be positively related to intelligence and intellectual curiosity.

Chamorro-Premuzic and Furnham’s (2008) confirm a positive relationship between the openness and academic achievement. They argue that open individuals are more likely to engage in activities that stimulate the acquisition of knowledge and learning experiences. Caprara et al. (2010) found that openness along with academic self-ef¬cacy contributed to junior high-school grades, after controlling for socio-economic status (SES). Graziano et al. (1997) assessed the Big Five self-reports of 5th to 8th graders. They found Openness positively related with both, self-reports and teacher ratings of academic adjustment. However, O’Connor and Paunonen (2007) reported in a review a very low correlation (r = .06) between openness and academic achievement. They rejected the idea of an overall interaction between the two variables.

Neuroticism

Neuroticism is the degree to which a person experiences negative emotions that are associated with irrational beliefs (Ellis, 1994), weak impulse control, and difficulty coping with stress. A number of studies report a negative correlation between neuroticism and academic performance (Chamorro-Premuzic & Furnham, 2003a, 2003b; Ridgell & Lounsbury, 2004), thereby indicating that academic performance tends to be higher in the case of emotionally stable students than neurotic students, who may experience higher levels of anxiety during stressful situations (O’Connor & Paunonen, 2007). However, results of meta-analyses examining the relationship between neuroticism and academic achievement remain inconclusive (O’Connor & Paunonen, 2007; Trapmann et al., 2007). Such studies suggest that neuroticism may not be a strong predictor of individual differences in academic achievement in general.

Agreeableness

Agreeableness may be defined as the disposition of a person toward nurturance, altruism, trust, and a willingness to help others. Studies examining the relationship between agreeableness and academic achievement have produced differing results. Gray and Watson (2002) and Farsides and Woodfield (2003) found agreeableness to be positively associated to GPA (r = .15 and r = .14 respectively). Deary et al. (2003), using the Big Five Inventory found that those who failed to complete the program scored lower on agreeableness. However, in other studies (Conard, 2006; Duff, Boyle, Dunleavy, & Ferguson 2004) researchers failed to find such a significant association between the two variables. Thus, agreeableness may not be that important a determinant of academic performance.

Extraversion

Extraversion is the degree to which individuals are sociable, preferring large groups and gatherings. Extroverts demonstrate a tendency to be cheerful, assertive and active. Although a positive relationship exists between IQ and Extraversion, Extraversion has been found in several studies (Busato, Prins, Elshout, & Hamaker, 2000; Furnham & Chamorro-Premuzic, 2004; Furnham, Chamorro-Premuzic, & McDougall, 2002) to be negatively associated with academic success. Early studies, in particular, indicated that introverts performed better than extroverts, suggesting that the former were better at revision and possessed a higher ability to learn (Entwistle & Entwistle 1970). More recently, Sanchez-Marin et al. (2001) found that extraverts failed their programs more frequently than introverts, again suggesting that this was to do with their distractibility, sociability, and impulsiveness. However, Furnham et al. (1998b) found that extroverts performed significantly better than introverts on a measure of logical reasoning. Chamorro-Premuzic and Furnham (2003) state that it is difficult to find a consistent relationship between intelligence and extraversion.

Overall, extraversion supports academic achievement in some studies and hinders it in others. It must be noted that several variables like age, educational level, gender and assessment method may moderate the relationship between the two variables.

In light of the preceding research, today it is more important than ever to determine the personality factors influencing academic success among college students, given the increasing levels of early withdrawal from college and their declining levels of academic performance (Tok & Morali, 2009). While a considerable amount of research has been undertaken to establish the relationship between personality factors and academic achievement, there is a virtual gap in study in this area in India. Thus, the present study is extends the earlier literature on personality-academic achievement relationship by studying the linkage between the two variables among B-school students in India. Based on the results of the previous research, we postulate that Conscientiousness as a personality variable would have the strongest impact on academic achievement.

Method

Participants

Data was collected from 158 respondents studying in the postgraduate program at XLRI. Convenience sampling technique was used to identify the respondents. The sample size comprised of a mix of participants belonging to the first year and second year HR and Business Management programs offered by the Institute.

Measures

Personality Measure: The Big Five Inventory (BFI) developed by John & Benet-Martinez (1998) was used to measure the five personality dimensions of Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The participants were asked to respond to 44 items on a 5 point Likert Scale with a score of 1 indicating “strongly disagree” and a score of 5 indicating “strongly agree.” Out of the 44 statements, eight items each measure Extraversion and Neuroticism; nine items each measure Agreeableness and Conscientiousness and ten items measure Openness to Experience. Sixteen items in all are reverse scored. John & Srivastava (1999) report the reliability coefficient of the BFI to be 0.83. The convergent validity for the instrument ranged from 0.73 to 0.81. Confirmatory factor analysis yielded a validity coefficient of 0.92 for the instrument.

Academic Achievement: The participants Cumulative Quality Points Index (CQPI) at XLRI at the time of the research study was used as a measure of academic achievement. The maximum CQPI that can be obtained by a student is 8.00. The CQPI, as a measure, was coupled with the percentage of marks obtained in the XII standard in school. Information on both these measures was obtained from the participants self-reports.

See appendix for specimen copy of the questionnaire used in the survey.

Data Analysis

Responses obtained from the participants were first recoded to take into account the negatively worded items. Thereafter, the scores on the five dimensions of the BFI were computed for each participant by summating the responses of the assigned items. In order to explore the relationship between personality factors and academic success, the Pearson’s Product Moment Correlation Coefficient was calculated between the Big Five Dimensions and the two measures of academic achievement, namely XLRI CQPI and XII standard percentage scored.

Results

The results indicate that Conscientiousness was significantly and positively associated with XII Standard percentage scores (r = 0.124, p < 0.05) and XLRI CQPI (r = 0.248, p < 0.01). Neuroticism was also found to be significantly and positively related to CQPI at XLRI (r = 0.164, p < 0.01), but not to XII standard scores.

No significant correlation was found between other personality factors and the measures of academic achievement.
