Are Letter Detection and Proofreading Tasks Equivalent?

When readers search for misspellings in a proofreading task or for a letter in a letter detection task, they are more likely to omit function words than content words. However, with misspelled words, previous findings for the letter detection task were mixed. In two experiments, the authors tested the functional equivalence of both tasks. Results reveal similar patterns of omissions for both search tasks when misspellings were produced by substituting one letter for another: There were more omissions for function words than for content words. However, when two letters were transposed, differences between the two tasks emerged. It is possible to conclude that letter detection and proofreading are based on common cognitive processes but the nature of the target can modulate the effects. Results are interpreted in light of the attentional disengagement model and the guidance organization model of the missing-letter effect.     

What do freshmen really know about research? Assess before you teach

The paper describes an effort to assess the information literacy skills of first year college students. An instrument was developed and information was gathered on students' experience and comfort in conducting library research as well as their perceived competence with specific information literacy skills. In addition, students completed a skills test to assess specific knowledge and skills relating to information literacy. Entering freshmen generally self-reported their skills to be less than “excellent.” This finding was supported by the results of the skills test. Strengths and weaknesses in information literacy skills are reported as well as implications for librarians who assess and teach these skills to students.     

Obesity: Analysis of Attitudes and Knowledge of Weight Control in Girls

Abstract

A questionnaire involving attitudes toward obesity, food, and physical exercise, and knowledge about weight control, was administered to 225 obese female adolescents and 213 controls. Results indicated an obsession on the part of the obese with their weight, to such an extent that nonrelated areas became involved in the issue. Despite the greater knowledge of the obese concerning weight control, and their more positive attitudes toward exercise, these factors seemed to have little effect in helping them deal with their obesity.     

Using Online Tutorials to Reduce Uncertainty in Information Seeking Behavior

ABSTRACT

Uncertainty is defined as affective symptoms of stress, anxiety, and frustration when faced with an information need. Traditional face-to-face instruction allows sender and receiver to fulfill information needs using multiple sources, which can be visual, auditory, tactile, or verbal. Distance learners may experience high levels of uncertainty when most or all of the communication and interaction takes place in an electronic environment that does not allow for these multiple information sources. Research on face-to-face communication and uncertainty suggests that people attempt to reduce uncertainty by acquiring more information and also by using structured or familiar information resources. This paper suggests that many of our behavioral motivations in face-to-face activities would also apply in the online environment. By creating online tutorials that combine structured hierarchical instructions with familiar modes of communication, we may be able to reduce symptoms of uncertainty in the library search process.
