Generating anagrams from multiple core strings employing user-defined vocabularies and orthographic parameters.

Anagrams are used widely in psychological research. However, generating a range of strings with the same letter content is an inherently difficult and time-consuming task for humans, and current computer-based anagram generators do not provide the controls necessary for psychological research. In this article, we present a computational algorithm that overcomes these problems. Specifically, the algorithm processes automatically each word in a user-defined source vocabulary and outputs, for each word, all possible anagrams that exist as words (or as nonwords, if required) as defined by the same source vocabulary. Moreover, we show how the output of the algorithm can be filtered to produce anagrams within specific user-defined orthographic parameters. For example, the anagrams produced can be filtered to produce words that share, with each other or with other words in the source vocabulary, letters in only certain positions. Finally, we provide free access to the complete Windows-based program and source code containing these facilities for anagram generation.

In search of perceptual influences of sentence context on word recognition.

A major issue in the study of word perception concerns the nature (perceptual or nonperceptual) of sentence context effects. The authors compared effects of legal, word replacement, nonword replacement, and transposed contexts on target word performance using the Reicher-Wheeler task to suppress nonperceptual influences of contextual and lexical constraint. Experiment 1 showed superior target word performance for legal (e.g., "it began to flap/flop") over all other contexts and for transposed over word replacement and nonword replacement contexts. Experiment 2 replicated these findings with higher constraint contexts (e.g., "the cellar is dark/dank") and Experiment 3 showed that strong constraint contexts improved performance for congruent (e.g., "born to be wild") but not incongruent (e.g., mild) target words. These findings support the view that the very perception of words can be enhanced when words are presented in legal sentence contexts.

Herbal and nonherbal alternative medicine use in Northwest Ohio.

OBJECTIVE: To determine the prevalence and characteristics of herbal and nonherbal alternative medicine use among adults living in northwest Ohio. DESIGN: Cross-sectional survey. SETTING: Three grocery store intercepts in northwest Ohio. SUBJECTS: A consecutive sample of 326 English-speaking persons > or =18 years old. METHODS: A 26-item survey self-administered to participants over a 6-month period. OUTCOME MEASURES: Prevalence of herbal remedy use. RESULTS: Forty percent of respondents have used an herbal remedy during the last 12 months. The average number of herbs used was 2.3 per person. Herbal remedy use was not associated with specific sociodemographic variables. Desire to improve general health was the most common reason for use of an herbal remedy (16%). Herbal users cited "herbals are natural" as the most common benefit. Magazines (17%), health food stores (16%), and friends (14%) were the most common sources of herbal remedy information. Only 50% of the population informed their physician of such use. Forty-one percent used an herbal remedy sometimes to always to self-treat before seeking medical care from a physician. Fifteen percent of adults treated their children with herbs. Nearly all (86%) respondents believed the herb was helpful or very helpful. CONCLUSIONS: A significant number of the adults surveyed in the Toledo metropolitan area commonly used complementary and alternative medicine (CAM). There were no independent factors associated with herbal remedy use. It is important for healthcare providers to acknowledge this growing trend of CAM therapy use and begin to incorporate open discussion about CAM into the patient-provider relationship.

Effectiveness of the Responsible Social Values Program for 6th grade students in one rural school district.

The present study reports the effectiveness of an abstinence-based program (the Responsible Social Values Program) designed for 6th grade students in a rural school district. To assess whether this 6-hr. abstinence-based program changed students' knowledge of their sexual development during adolescence, attitudes toward early sexual involvement, intentions regarding sexual involvement, views related to expected consequences of being sexually involved, and views related to expected outcomes of being sexually involved, a pre-experimental one-group, pretest-posttest design was employed. Analysis indicated that the curriculum was effective in terms of improving scores for each of the constructs measured. Immediately after the 6-hr. program, more students stated that they planned to avoid having sex until marriage (70%) than prior to the program (50%). Replication with a control group and longer term follow-up testing is necessary.

Determining the influence of Gaussian blurring on inversion effects with talking faces.

Perception of visual speech and the influence of visual speech on auditory speech perception is affected by the orientation of a talker's face, but the nature of the visual information underlying this effect has yet to be established. Here, we examine the contributions of visually coarse (configural) and fine (featural) facial movement information to inversion effects in the perception of visual and audiovisual speech. We describe two experiments in which we disrupted perception of fine facial detail by decreasing spatial frequency (blurring) and disrupted perception of coarse configural information by facial inversion. For normal, unblurred talking faces, facial inversion had no influence on visual speech identification or on the effects of congruent or incongruent visual speech movements on perception of auditory speech. However, for blurred faces, facial inversion reduced identification of unimodal visual speech and effects of visual speech on perception of congruent and incongruent auditory speech. These effects were more pronounced for words whose appearance may be defined by fine featural detail. Implications for the nature of inversion effects in visual and audiovisual speech are discussed.

Perceptions and use of smoking cessation in nurse-midwives' practice.

The objective of this study was to examine Ohio nurse-midwives' perceptions and use of a smoking cessation protocol in assisting pregnant smokers. The total population of licensed Ohio nurse-midwives (n = 300) was surveyed by using a cross-sectional survey design. Only 4 of 10 items that assessed a nationally recommended method of promoting smoking cessation were done by 50% or more of respondents. Few nurse-midwives identified barriers to counseling pregnant patients who smoked, but the most common were lack of time (14%) and not knowing where to send pregnant smokers for treatment (14%). Most respondents believed that nicotine replacement therapy (NRT) would be most likely to reduce the number of pregnant smokers (74%), yet few (26%) were confident in their ability to prescribe/recommend nicotine replacement therapy. Respondents more likely to use 5 A's can be characterized as the following: had higher efficacy expectations in their ability to communicate issues about the 5 A's and had higher outcome expectations regarding the effects of using the 5 A's. Nurse-midwife training programs and continuing education needs to include current research in nicotine replacement therapy use in pregnant patients and 5 A's techniques to assist pregnant smokers in quitting.

Development of a social will for tobacco control index.

OBJECTIVE: To design a valid and reliable questionnaire to assess community support for controlling tobacco. METHODS: Four samples were obtained to test the psychometric properties of the Social Will for Tobacco Control Instrument. RESULTS: Principal components analysis found 2 factors accounted for 42.8% (personal support) and 9.7% (agency support) of the variance, respectively. Sensitivity was 93.7%, specificity was 90.6%, and validity was 92.3%. The instrument predicted, within 1%, the actual vote regarding a local clean indoor air ordinance. Stability reliability was .84 and .77 respectively for the 2 factors. CONCLUSION: The SWTCI can help policy makers predict whether communities are supportive of clean indoor air ordinances.

Pediatricians' practices regarding smoking cessation among parents of their patients.

OBJECTIVE: To assess pediatricians' use of the 5A's for smoking cessation among the parents of their patients. METHODS: A random sample of Ohio pediatricians (n=153) completed a mail survey on smoking cessation activities. RESULTS: Most pediatricians (80%) regularly asked their patients' parents about their smoking status. The majority "always" or "usually" implemented 2 of the 5 steps of the 5A's. Respondents perceived using the 5A's would result in fewer parents smoking but were less confident they could implement all of the 5A's. CONCLUSIONS: Pediatricians need more training to better prepare them to assist parents in quitting smoking.
