Adults' prior exposure to print as a predictor of the legibility of text on paper and laptop computer

This study investigated the effects of variations in graphic elements that account for differences in speed and accuracy between reading text aloud from paper versus laptop computer. Variations in accurate reading-aloud performance are attributable to individual differences in the visual accessibility of information due to (1) the experimental manipulations of the independent variables, (2) the subjects' prior exposure to print within the culture, and (3) the educational attainment of the subject. A non-representative sample of 48 female survey interviewers (ages 38–72) were employed in the conduct of this study. Survey interviewers were selected because they gather information using laptop computers; the quality of the survey information collected may be directly associated with the legibility of computerized text on reader performance. Subjects completed a prior exposure to print questionnaire (Stanovich & West 1989) and a demographic data form (IDIQ). Repeated-measures analyses of variance were employed to examine individual differences in the speed and accuracy of reading-aloud performance for twenty-four conditions varying the levels of independent variables including: (1) Font (Times Roman, Helvetica, and Courier), (2) Justification (fully- justified versus left-justified), (3) Leading (single-spaced versus double-spaced), and (4) Mode of Presentation (paper versus laptop computer). Linear regression analyses found subjects' prior exposure to print significantly and positively related to predicting speed and miscue performance. The subjects' educational attainment significantly predicted miscue performance. Subjects' ages were not significantly related to performance. Results of this study inform computer programmers and designers who are responsible for developing standards and guidelines for legible computerized text for the effective access of accurate information.     

Developmentally Appropriate Practice and a National Literacy Strategy

This paper questions the introduction of national teaching strategy for all ages from five to eleven. It is proposed that the lack of developmentally appropriate practice in the early teaching of literacy is inappropriate and may be counter-productive to the long term goals of high literacy standards.     

Goal setting,responsibility training,and fixed ratio reinforcement: Ten-month application to students with emotional disturbance in a public school setting

Reviews of treatment strategies for students with emotional disturbance (ED) have noted that most studies (a) do not involve entire classes or groups of classes, (b) are not conducted in public schools, and (c) do not report data for an entire 10-month school year (September to June). This study applied goal setting (GS), responsibility training (RT), and fixed ratio reinforcement (FRR) to three classes of students with ED in a public elementary school from September to June. GS included daily, weekly, and monthly goals for behavior and work earnings (points). RT included a level system with different reinforcers and privileges for each level, and nonisolated time out with problem solving. FRR included reward contingencies for behavior and work earnings. Data for 10 months indicated that (a) goals were consistently earned at high levels, (b) the percentage of students attaining higher RT levels progressively increased, and (c) time-out levels progressively decreased, with year-end spikes below prior peak levels. Findings supported the use of GS, RT, and FRR for students with ED in public school to encourage appropriate behavior and work effort over 10 months. Method limitations and research implications are discussed.     

The Effect of In-Season Traditional and Explosive Resistance Training Programs on Strength,Jump Height,and Speed in Recreational Soccer Players

Purpose: Resistance training is often performed in a traditional training style using deliberate relatively longer repetition durations or in an explosive training style using maximal intended velocities and relatively shorter repetition durations. Both improve strength, “power” (impulsivity), and speed. This study compared explosive and traditional training over a 6-week intervention in 30 healthy young adult male recreational soccer players. Method: Full body supervised resistance training was performed 2 times a week using 3 sets of each exercise at 80% of one repetition maximum to momentary failure. Outcomes were Smith machine squat 1 repetition maximum, 10 meter sprint time, and countermovement jump. Results: Both groups significantly improved all outcomes based on 95% confidence intervals not crossing zero. There were no between-group differences for squat 1 RM (TRAD = 6.3[5.1 to 7.6] kg, EXP = 5.2[3.9 to 6.4] kg) or 10 meter sprint (TRAD = ?0.05[?0.07 to ?0.04] s, EXP = ?0.05[?0.06 to ?0.03] s). Explosive group had a significantly greater increase in countermovement jump compared to the traditional group (TRAD = 0.7[0.3 to 1.1] cm, EXP = 1.3[0.9 to 1.7] cm). Conclusion: Both the traditional training and explosive training performed to momentary failure produced significant improvements in strength, speed, and jump performance. Strength gains are similar independent of intended movement speed. However, speed and jump performance changes are marginal with resistance training.
