The role of IQ, expertise, and motivation in the recall of familiar information

High- and low-IQ children in the first, third, and fifth grades performed two free-recall tasks: a sort-recall task with sets of categorically related pictures, and a class-recall task, with children recalling the current members of their school class. All children were deemed to be experts concerning the composition of their school class, but, unlike experts in other domains, had no special motivation associated with their expertise. Recall and clustering on both tasks were high. The high-IQ children performed better than low-IQ children only on the sort-recall task. IQ was significantly correlated with measures of performance on the sort-recall task but not on the class-recall task. The results reflect the fact that the memory benefits associated with being an expert (here, elimination of IQ effects) are related to the greater knowledge the expert possesses and not to factors of motivation.     

Components of reading comprehension and scholastic achievement

The aim of this study was to understand whether the reading comprehension process is better explained by a single or by multiple factors. 184 students (9 to 13 years old) were presented with a recently devised battery of tests, that measure ten aspects of reading comprehension. Structural equation modelling showed that a two factors model better accounts for the data compared to a one or a three factors model. Results confirmed the hypothesis which distinguishes between ‘basic’ and ‘complex’ aspects of reading comprehension. The second goal of the study was to analyze the relationship between the two-components model and scholastic achievement. Our results highlighted that the more ‘complex’ aspects of reading comprehension, reflecting some metacognitive knowledge and control processes, are the better predictors of scholastic achievement.     

Fostering the Development of Reading Skill through Supplemental Instruction: Results for Hispanic and Non-Hispanic Students

This paper reports the effects of a two-year supplemental reading program for kindergarten through third grade students that focused on the development of decoding skills and reading fluency. Two hundred ninety-nine students were identified for participation and were randomly assigned to the supplemental instruction or to a no-treatment control group. Participants' reading ability was assessed in the fall, before the first year of the intervention, and again in the spring of years 1, 2, 3, and 4. At the end of the two-year intervention, students who received the supplemental instruction performed significantly better than their matched controls on measures of entry level reading skills (i.e., letter-word identification and word attack), oral reading fluency, vocabulary, and comprehension. The benefits of the instruction were still clear two years after instruction had ended with students in the supplemental-instruction condition still showing significantly greater growth on the measure of oral reading fluency. Hispanic students benefited from the supplemental reading instruction in English as much as or more than non-Hispanic students. Results support the value of supplemental instruction focused on the development of word recognition skills for helping students at risk for reading failure.     

Speech perception and speech production as indicators of reading difficulty

In order to investigate the relation between reading accuracy and speech processing, 20 children from grades 2 and 3 who were skilled in reading were compared with 20 less skilled readers on a speech perception and production task. The two groups of readers were indistinguishable in their production of the two-syllable words dippy, deepy, tippy, and teepy and in their perception of the stop consonants /d/ versus /t/. Less skilled readers were significantly less accurate than the skilled readers in a vowel identification task involving the lax and tense high vowels /i/ and /i/. The error pattern for vowel identification was similar across groups, with both groups making fewer errors when short and longer segments were alternated. The results imply that vowel phonemes are less securely represented in the perceptual system of less skilled readers than are consonant phonemes. In addition, the results raise the possibility that a selective perceptual impairment underlies at least some of the phonemic awareness problems that have been associated with poor reading.     

Adaptation and Pilot Testing of a Sexual Health Intervention for Female Survivors of Violence

Experiences of violence and behaviors that increase the risk of acquiring a sexually transmitted infection are high among women in the United States, and they often intersect (Meyer, Springer, &; Altice, 2011 Meyer, J. P., Springer, S. A., &; Altice, F. L. (2011). Substance abuse, violence, and HIV in women: A literature review of the syndemic. Journal of Women's Health (2002), 20(7), 991–1006. doi:10.1089/jwh.2010.2328[Crossref] , [Google Scholar]; Montgomery et al., 2015 Montgomery, B., Rompalo, A., Hughes, J., Wang, J., Haley, D., Soto-Torres, L., &; Hodder, S. (2015). Violence against women in selected areas of the united states.e1-e11. Am J Public Health, 105(10), 2156–2166 [Google Scholar]; World Health Organization (WHO), 2010 World Health Organization (WHO). (2010). Addressing violence against women and HIV/AIDS: What works?. Geneva, Switzerland: World Health Organization. [Google Scholar]). However, there are few evidence-based HIV-prevention interventions that address the special needs and challenges faced by female survivors of violence (Centers for Disease Control and Prevention, (CDC), 2017a Centers for Disease Control and Prevention. (2017a). Compendium of evidence-based interventions and best practices for HIV prevention. Atlanta, GA: Division of HIV/AIDS Prevention, National Center for HIV/AIDS, Viral Hepatitis, Sexual Transmitted Diseases and Tuberculosis Prevention. Retrieved from https://www.cdc.gov/hiv/research/interventionresearch/compendium/rr/index.html [Google Scholar]). To address this gap, we adapted and pilot-tested an existing evidence-based women-focused sexual risk-reduction intervention (The Future Is Ours) with 23 self-identified female survivors of violence. The intervention comprised eight-weekly, two-hour cognitive behavioral group sessions focusing on reducing sexual-risk and improving trauma-based coping skills. Using mixed-methods analyses, the adapted intervention was determined feasible and acceptable to participants, and preliminary results suggest that participation could reduce risk factors for sexually transmitted infections. Therefore, testing on a larger scale is warranted.     

Effects of a First-Semester Learning Community on Nontraditional Technical Students

The study consisted of 25 full-time Electronic Technician Certificate students with 16 randomly assigned to an experimental group registered in a team-taught learning community and with nine randomly assigned to a control group registered for individually taught unlinked classes. We hypothesized that the experimental group would have significantly better academic and social integration and more positive perceptions of their experiences than the control class as well as higher course grades and grade point averages, more contact with classmates and instructors, and greater commitment to college and second semester persistence. Both student self-reported surveys and institutional data were analyzed. Results indicated that the team-taught learning community did make a difference to its students and yielded quantitative and qualitative support for hypotheses dealing with student perceptions of academic and social integration. Findings failed to support hypotheses dealing with behavioral outcomes except for strong support for commitment to college.     

Prolog programming techniques

In this paper we introduce the concept of a Prolog programming technique. This concept is then distinguished both from that of an algorithm and that of a programming cliché. We give examples and show how a knowledge of them can be useful in both programming environments and in teaching programming skills. The extraction of the various techniques is outlined. Finally, we discuss the problem of representing techniques where we conclude that the most promising approach is the development of a suitable meta-language.
