Cognitive interference in computer anxiety

This study investigated the sources of cognitive interference in high vs. low computer anxious university students. A total of 149 psychology undergraduates were administered measures of computer anxiety, trait anxiety, computer experience and positive and negative thoughts associated with computers and computer use. It was hypothesized that individuals high in computer anxiety would report a greater number of debilitative thoughts than individuals low in computer anxiety. However, individuals high in computer anxiety were expected to report more on-task thoughts than individuals low in computer anxiety. In support of the hypotheses, a multivariate analysis of variance revealed that the high computer anxious group reported experiencing significantly more negative evaluations, off-task thoughts and negative computer cognitions than the low computer anxious group. In addition, the high computer anxious group reported fewer computer enjoyment cognitions than the low computer anxious group. Contrary to previous research findings, computer anxiety was not related to on-task thoughts when statistically controlling for off-task thoughts. The results are discussed in light of cognitive models of anxiety and prior research.     

Assessing the computer attitudes of students: An Asian perspective

Research has found that computer attitudes play a key role in influencing the extent to which students accept the computer as a learning tool and in determining the likelihood that computer will be used in the future for learning and study. A sample of 183 students reported their computer attitudes using a Likert-type questionnaire with three subscales, computer importance, computer enjoyment, and computer anxiety. One-way MANOVA revealed no significant differences in computer attitudes by gender although male students reported more positive towards the computer than female students. There were significant differences between students who own computers at home and those who do not and students who own a computer at home also reported a lower level of computer anxiety compared to those who do not.     

Computer anxiety and perception of task complexity in learning programming-related skills

The purpose of the study was to investigate how computer anxiety is associated with computer task complexity in teaching and learning computer programming and related skills. The study also examined the effects of computer confidence and computer liking on user perception of task complexity. The study referred to the literature concerning whether enhancing computer experience may be the remedy of computer anxiety. Based on the data regarding different computer task levels, the study identified and tested the regression models using path analysis.The result of the study indicates that computer confidence had significant effects on user perception of task complexity while the effects of computer liking were minimal. At various task levels, increasing computer experience may help reduce computer anxiety. The individuals at a lower task level had less adequate estimation of task complexity than those at higher task levels, and thus were more likely to be subject to occurrence of computer anxiety. The study recommends that in teaching and learning computer programming and related skills, enhancing the knowledge and understanding of task complexity is necessary. It can help computer learners and users, especially at lower skill levels, in dealing with computer anxiety.

A contingency model of computer and Internet self-efficacy

Information system researchers have recently devoted considerable attention to the concept of computer self-efficacy in order to understand computer user behavior and system use. This article reports on the development and examination of a contingency model of computer and Internet self-efficacy. User attitude and computer anxiety were assumed to influence the development of computer and Internet self-efficacy. Measures of user attitude, computer anxiety, computer self-efficacy, and Internet self-efficacy were used in a university environment to collect 347 responses at both the beginning and end of an introductory computer course. Results suggested that training significantly improved computer and Internet self-efficacy. Respondents with ‘favorable’ attitudes toward computers improved their self-efficacy significantly more than respondents with ‘unfavorable’ attitudes. Respondents with ‘low’ computer anxiety improved their self-efficacy significantly more than respondents with ‘high’ computer anxiety. The interaction effect between attitude and anxiety was significant for computer self-efficacy scores but not for Internet self-efficacy scores. The implications of these findings are discussed.

Development and validation of a computer expertise questionnaire for older adults

Prior computer expertise represents one of the most important predictors of performance when interacting with ICT (Information and Communication Technologies) and acquiring computer skills. Due to demographic changes, the older adult will become increasingly important as a potential user. However, there is a lack of instruments for the assessment of computer expertise in older adults, especially for novice users with restricted prior computer knowledge. A computer expertise (CE) questionnaire for older adults was developed, analysed (Study I) and validated (Study II). Item-analysis showed that the CE-questionnaire is particularly appropriate for the computer knowledge level of older adults and measures computer expertise sufficiently. Furthermore, it was found that computer experience (in terms of frequency of computer usage) is a poor predictor of actual computer performance, which has important implications for the theoretical conceptualization of computer expertise and its assessment.

Modeling computer interest in older adults: the role of age, education, computer knowledge, and computer anxiety

We proposed a mediation model to examine the effects of age, education, computer knowledge, and computer anxiety on computer interest in older adults. We hypothesized that computer knowledge and computer anxiety would fully mediate the effects of age and education on computer interest. A sample of 330 older adults from local senior-citizen apartment buildings completed a survey that included an assessment of the constructs included in the model. Using structural equation modeling, we found that the results supported the hypothesized mediation model. In particular, the effect of computer knowledge operated on computer interest through computer anxiety. The effect of age was not fully mitigated by the other model variables, indicating the need for future research that identifies and models other correlates of age and computer interest. The most immediate application of this research is the finding that a simple 3-item instrument can be used to assess computer interest in older populations. This will help professionals plan and implement computer services in public-access settings for older adults. An additional application of this research is the information it provides for training program designers.

Computer anxiety in individuals with serious mental illness

This study was designed to compare computer anxiety in individuals with severe mental illness to a normative college sample and to examine whether computer training would be effective in reducing computer anxiety in individuals with severe mental illnesses. The Computer Anxiety Rating Scale (CARS) was used to assess the self-reported computer anxiety of 30 individuals with severe psychiatric disorders enrolled in computer training at a mental health facility's employment training center. The CARS was administered prior to training, after 1 month of training, and after 3 months. Anxiety levels before computer training began were compared to the computer anxiety levels of 35 community college students enrolled in a course providing similar computer training. The individuals with severe mental illness were found to have significantly higher initial computer anxiety scores than the comparison group. Computer anxiety was not significantly reduced by the computer training in either group.     

新型联动报警系统

提出对传统报警系统改进的办法:用PC机作为主机,用AT89S52单片机作为从机,采用RS485总线型网络系统。该系统的特点:(1)不仅主机可以呼叫从机,从机在必要时可以主动呼叫主机,避免了从机只能等待主机轮询访问的弊端,从而提高了系统实时性和可靠性;(2)由于报警的时间毕竟很少,因此没有必要让主机无休止地轮询访问各个从机。而且轮询的方式效率很低,主机未必能从多台从机中立刻定位到报警的那台从机。     

Effects of computer use during coursework on computer aversion

To test the impact of computer experience on computer aversion, 1542 students, enrolled in 32 sections of an Introductory Psychology course utilizing a computerized tutorial program were surveyed. The 32 sections were also randomly assigned to three teaching formats that involved differing levels of computer tutorial usage. Measures of computer aversion, computer attitudes, and computer anxiety were administered three times during the course and analyzed to reveal differential change patterns stemming from courseware use which were based upon gender and preexisting computer anxiety levels. These observed changes are discussed in relation to students' reinforcement, efficacy, and outcome expectations from computer use.
