RESUMO
Verbs are one of the basic building blocks of grammar, yet few studies have examined the grammatical, morphological, and phonological factors contributing to lexical access and production of Spanish verb inflection. This report describes an online data set that incorporates psycholinguistic dimensions for 50 of the most common early-acquired Spanish verbs. Using this data set, predictors of response time (RT) from stimulus onset and mean differences at offset are examined. Native Spanish speakers, randomly assigned to one of two tasks, listened to prerecorded verbs and either repeated the verb (single word shadowing) or produced its corresponding pronoun. Factors such as stimulus duration, number of syllables, syllable stress position, and specific levels of initial phoneme facilitated both shadowing of a verb and production of its pronoun. Higher frequency verbs facilitated faster verb repetition, whereas verbs with alternative pronouns increased RT to pronoun production. Mean differences at offset (stimulus duration is removed) indicated that listeners begin speaking earlier when the verb is longer and multisyllabic compared to shorter, monosyllabic words. These results highlight the association between psycholinguistic factors and RT measures of verb processing, in particular, features unique to languages like Spanish, such as alternative pronoun and tense.
RESUMO
BACKGROUND: Mammography self-report is used to monitor screening and evaluate intervention trends; however, few studies have examined reliability. METHODS: Reliability of self-reported lifetime number of mammograms, most recent mammogram date, and predictors of reliability were assessed using data from Project H.O.M.E. The study population was 2,494 women 52 years and over, listed in the U.S. National Registry of Women Veterans, with no history of breast cancer, who completed both baseline (2000-2002) and year 1 (2002-2003) surveys. RESULTS: Reliability of lifetime number of mammograms was 60.9% for exact consistency and 79.9% for consistency within one mammogram. Thirty-five percent was exactly consistent in reporting mammogram date; 55.6% was consistent within 3 months. Completing both surveys by mail and reporting fewer lifetime mammograms at baseline were positively associated with consistency of reporting lifetime number. White race/ethnicity, having a Bachelor's degree, reporting a health care provider's recommendation for a mammogram, having a screening mammogram, completing both surveys by mail, and being in the maintenance or action stages of change were associated with consistency in reporting date. CONCLUSIONS: Reliability varies with the measure of self-reported mammography. Likewise, predictors show different patterns of association with different definitions. Our findings call attention to the need for explicit definitions and measures of mammography use.
