1、.The Journal of Genetic Psychology. 2005, 160(4), 436-442The Effects of Locus of Control and Task Difficulty on ProcrastinationTRACY JANSSEN Department of Psychology Beloit College JOHN S. CARTON Department of Psychology Oglethorpe UniversityABSTRACT. The authors investigated the effects of locus of

2、 control expectancies and task difficulty on procrastination. Forty-two college students were administered an academic locus of control scale and a task that was similar to a typical college homework assignment.The students were randomly assigned to 1 of 2 task difficulty levels. Although none of th

3、e results involving task difficulty was significant, several results involving locus of control were significant. Specifically, analyses revealed that students with internal locus of control expectancies tended to begin working on the assignment sooner than students with external locus of control ex

4、pectancies. In addition, students with internal locus of control completed and returned the assignment sooner than students with external locus of control. The results are discussed within the context of J. B. Rotters (1966, 1975, 1982) social leaming theory. PROCRASTINATION refers to the act of nee

5、dlessly delaying a task until the point of some discomforta behavior problem that many adults experience on a regular basis (Ferrari, Johnson,&McCown, 1995). Most research on procrastination has focused on college students; researchers have estimated that anywhere from 46% (Solomon&Rothblum, 1984) t

6、o 95% (Ellis&Knaus, 1977) of college students regularly procrastinate on academic assignments. Research findings suggest that, the longer students are in college, the more they tend to procrastinate (Semb, Glick,&Spencer, 1979), although most students perceive such behavior as a problem that they wo

7、uld like to eliminate (Solomon&Rothblum,1984). In addition, procrastination has been associated with a variety of difficulties, including test anxiety, missed deadlines for assignments, poor semester grades, depressed affect, low self-esteem, and social anxiety (e.g., Beswick,Rothbun,&Mann,1988;Ferr

8、ari,1991;Ferrari et al.,1995;Lay,1986,1987;Lay&Burns,1991;Solomon&Rothblum,1984) TO better understand Procrastination,researchers have sought to identify personality variables associated with it(for a review,see Ferrari et al.,1995)One variable that has been studied is locus of control of reinforcem

9、ent. locus of control refers to a generalized expectancy reflecting the degree to which individuals perceive consequences as contingent on their own behavior and abilities(internal control)rather than on some external force such as luck,chance,fate,or powerful others(external control;Rotter,1990).Be

10、cause individuals with internalcontrol expectancies perceive a contingent relation between their behavior and consequences,one might expect them to procrastinate less than individuals with external control expectancies. Previous research on the relation between locus of control and academic procrast

11、ination has produced mixed results.Several researchers have found no relation between the two variables (e.g.Briordy,1980; Ferrari,Parker,&Ware,1992).However, Trice and Milton(1987)found that procrastinators had grater external locus of control than nonprocrastinators. In addition,Rothblum,Solomon,a

12、nd Murakami found that procrastinators were more likely than nonprocrastinators to attribute success on exams to external factors.One reason for the inconsistent findings may be that most researchers have used generalized expectancy scales instead of specific academic expectancy scales to predict ac

13、ademic procrastination(Trice,1985). According to Rotters(1966,1975,1982)social learning theory,domainspecific expectancy scales should provide better predictions of specific behaviors than genera1ized scales do. In the present study,we sought to extend previous research on the relation between locus

14、 of control and academic procrastination in several ways.First,we used a specific expectancy scale for academic performance in order to measure studentslocus of control.Second,to measure procrastination and improve the external validity of the findings,we used a behavioral measure of procrastination

15、 that was similar to a typical course assignment,whereas many previous studies have used self-report scales.Third,to better understand the process of procrastination,we operationally defined procrastination in several ways:time taken to initiate an assigned task,time taken to complete the assigned t

16、ask,and time takento return the assigned task.Previous researchers have assessed only the date at which an assignment was returned,a procedure that makes it impossible to determine whether there were differences between individuals with internal and external control expectancies with respect to when

17、 they started and completed the task.Fourth,to investigate the effects of task difficulty on Procrastination,we assigned two different tasks.The hypotheses for the study were as follows: Hypothesis 1: Students with internal control expectancies will procrastinate less than those external control exp

18、ectancies. Hypothesis 2: Students who receive the difficult assignment will procrastinate more than those who receive the easy assignment. Hypothesis 3: There will be an interaction between locus of control and task difficulty, such that students with external locus of control expectancies who recei

19、ve the difficult assignment will procrastinate the most.MethodParticipants The participants for the study were 42 undergraduate students(10 men and 32 women). Their mean age was 19.7 years (SD=0.65). The students were enrolled in two psychology courses at a relatively small, midwestern U.S. college.

20、College students were selected so that we could replicate previous studies and because of the relatively high rates of procrastination observed in this population.The students were predominantly Caucasian (90%) and middle class. They received credit toward their course grade for their participation.

21、Measures Locus of control. Students completed the Academic Locus of Control Scale(ALC; Trice, 1985). The ALC is a 28-item, true-false scale designed to assess locus of control with respect to academic outcomes, with higher scores indicating greater externality. Trice (1985) reported a Kuder-Richards

22、on 20 internal consistency coefficient of 0.70 and a 5-week test-retest reliability coefficient of 0.92 for the ALC with college students. In addition, scores on the ALC have been shown to be correlated in predicted directions with academic achievement, class participation, homework completion, and

23、scores on the Rotter Internal-External Control Scale (Trice, Ogden, Stevens,&Booth, 1987). Procrastination. We measured the students procrastination by recording the amount of time that passed between the date the task was assigned and the dates the students began, completed, and returned the task t

24、o the teaching assistant.Specifically, the students were asked to take home a psychology article, read it,provide written answers to two questions about the article, and return their answers to the professors teaching assistant. The questions about the article were presented on a work sheet that als

25、o included places for the students to record the times and dates they started, completed, and returned the assignment to the teaching assistant (the return date was verified by the teaching assistant, who checked the return box daily). Task difficulty. We manipulated task difficulty by using two art

26、icles of equal length and similar topic but of presumably different difficulty levels. The easy article was an article on human memory, written for the general public, in the magazine Psychology Today (Neimark, 1995). The difficult article was a research article on human memory taken from the journa

27、l Psychological Science(Robinson&Roediger,1997). To check the difficulty manipulation, we asked the students to rate on a 5-point scale how difficult they perceived the article they were assigned(1=very easy, 5=very difficult).Procedure The students were randomly assigned to receive either the easy

28、or the difficult article. At the beginning of the semester, the students were administered a consent form and the ALC. After the forms were completed, the professor (a 32-year-old, male, Caucasian, assistant professor) assigned the articles and work sheets. The students were instructed to return the

29、 work sheets to the professors teaching assistant (a 21-year-old, female, Caucasian, senior college student) for grading as soon as they were done. Thus, no specific due date was provided (in order to enhance variability in procrastination), although the students had beentold that the assignment had

30、 to be completed by the end of the semester. After all of the work sheets were returned, the students were debriefed on the purpose of the study.Results Scores on the ALC were analyzed to determine each students locus of controt. Scores ranged from 3 to 18, with an overall mean of 9.64 (SD=3.81). Se

31、parate analyses for men and women resulted in the following means: men, 10.10(SD=2.85); women, 9.50 (SD=4.09). The mean scores for each gender were not significantly different, and they were comparable to means reported by Trice(1985) for college students. Students were separated at the median (9) i

32、nto internal (n=22) and external (n=20) control groups. A 2 x 2 x 2 analysis of variance was used to analyze the data. The independent variables were students gender (male, female), locus of control (internal,external), and task difficulty (easy, difficult). The dependent variables were the number o

33、f days between the date the article was assigned and the dates the students reported beginning, completing, and returning the assignment. To check the task difficulty manipulation, we first analyzed the students ratings of the difficulty levels of the two articles. As expected, there was a significa

34、nt main effect of task difficulty, F(1,41)=11.91,P0.01,indicating that the students rated the research article (M=3.90) as more difficult to complete than the magazine article (M=2.62). With respect to the first hypothesis, there was a marginally significant main effect of locus of control when proc

35、rastination was defined as the number of days that passed before students began the assignment, F(1, 41)=3.04, p0.09. Thus, there was a tendency for students with internal control expectancies (M=5.55 days) to begin the assignment earlier than students with external control expectancies (M=8.25 days

36、). When procrastination was defined as the number of days that elapsed before students reported completing the assignment, there was a significant main effect of locus of control, F(l, 41)=6.54, p0.01. As predicted, students with internal locus of control (M=6.05 days) took fewer days to complete th

37、e assignment than students with external locus of control (M=9.95 days). Finally, analysis of the number of days it took students to return the assignment revealed a significant main effect of locus of control, F(l, 41)=6.23, p0.05. As predicted, students with internal locus of control (M=7.64 days)

38、 took fewer days to return the assignment than students with external locus of control(M=12.15 days). Although several mean differences involving the task difficulty variable were in the predicted direction, none were statistically significant. In addition,there were no significant two- or three-way

39、 interactions on any dependent variable. Thus, the second and third hypotheses received no support. Moreover,there were no gender differences found on any measure, and an analysis of covariance holding age constant indicated that age differences did not account for the current results.Discussion Res

40、earch has indicated that procrastination involves more than poor time-management skills. Rather, it involves a combination of affective, behavioral, and cognitive factors (Ferrari et al,1995; Solomon & Rothblurm, 1984). The results of the present study suggest that one cognitive factor is locus of c

41、ontrol of reinforcement. Specifically, in this study, the students with internal control expectancies for academic outcomes took less time to complete and return the academic assignment than did the students with external control expectancies. There also was a trend for the students with internal lo

42、cus of control to let fewer days passbefore beginning to work on the assignment than did the students with external locus of control. The effect of locus of control on students procrastination did not depend on the difficulty level of the assignment, as indicated by the nonsignificant interaction be

43、tween locus of control and task difficulty. However, additional research with other tasks seems warranted before one can conclude that task difficulty does not have an effect on procrastination. Although the students perceived the research article as more difficult than the magazine article, it is p

44、ossible that there was not a large enough difference in the difficulty levels of the two articles to produce significant results in the present study. The relatively small sample size in the present study also may have contributed to the lack of significant findings regarding the task difficulty var

45、iable. As noted in the introduction, previous research examining the relation between locus of control and procrastination has produced mixed results. On the basis of the present results, we believe that there is a relation between the two variables and that the inconsistency in earlier findings may

46、 be attributable to two factors: (a) Researchers often have administered generalized expectancy scales instead of specific academic expectancy scales to predict academic behavior; and (b) researchers have used different self-report scales to measure procrastination,and it is not currently known how

47、well the different measures are correlated with one another. The present results are consistent with predictions based on Rotters social learning theory for behavioral differences between individuals with internal or external locus of control expectancies. The individuals who perceived a contingent

48、relation between their behavior and environmental consequences procrastinated less than the individuals who perceived consequences as contingent on external factors such as luck, chance, or fate. Given that locus of control expectancies can be measured reliably by the time children are of preschool

49、age (e.g., Mischel, Zeiss,&Zeiss, 1974; Skinner, 1986; Stephens&Delys, 1974)and probably before procrastination habits developone can conclude that locus of control precedes and contributes to procrastination. However,because the present study was cross-sectional and correlational in design, it is i

50、mpossible to conclusively determine the direction of causality. Thus, it is possible that procrastination contributes to locus of control or that the relation between the two variables is bidirectional. Future longitudinal research may help to determine the direction of causality. Another limitation

51、 of the present study is that the findings cannot be generalized beyond primarily Caucasian students attending college in the United States. Although it is important to study this population in order to compare the present results with the results of previous research, studies are needed with partic

52、ipants of different ages, ethnicities, and occupations to determine the robustness of the findings.REFERENCESBeswick, G,Rothbun, E. D,&Mann, L. (1988).
