We examined the factor structure and internal consistency reliability of the Spanish version of the Vividness of Visual Imagery Questionnaire which was applied to a sample of 850 secondary school students. Factor structure investigated by principal components analysis, followed by varimax orthogonal rotation, indicated that a single factor explained 37% of the variance. The internal consistency of the questionnaire was good (Cronbach alpha=.88). We conclude that the Spanish version of the questionnaire, like the English version, has a single factor and high internal consistency reliability.
This research is focused on mnemonic keyword method to enhance vocabulary mastery to the university students. Mnemonic refers to instructional or learning strategies designed specifically to enhance memory. One of the most powerful mnemonic strategies is the key word method. The keyword method is a useful mnemonic aid which can help broaden students' vocabulary by means of speech and ultimately with reading and writing. Then keyword method effective way to provide a meaningful visual image upon which to base memory for a new word's meaning. This research involves twenty students at the first grade. The research instruments of this study are consisted of tests, observation checklist, and a questionnaire. This study was class action research. From the cycle 1 reflection result, some procedures and activities were revised. Different from the cycle 2, the researcher used mnemonic keyword method and there is no reflection. The enhancement of students' vocabulary mastery shows with individual test and got mean score 67.75 in the cycle 1 and 79.75 in the cycle 2.In addition the enhancement of students' vocabulary mastery in group test and got mean score 72.00 in the cycle 1 and increased to be 81.00 in the cycle 2. In this result, it shows there enhancement for vocabulary mastery through mnemonic keyword method in the first grade students at STKIP PGRI Blitar. Introduction Vocabulary is an essential lesson for students to master in English. As a

In ¡he present study we aimed ¡o investigate whether immediate or delayed recail are affected by keywcrd generation method (experimenter or peer generation).

The subjects' imaging capacity was evaluated by means of (he Vividness of Visual lmagery Questionnaire (VVIQ) and the Spatial Test of Primary Mental Abiliries (ST-PMA). The results were analysed by multivariate analysis of variance (MANOVA) with three factors (ST-PMA imaging capacity, 2 levels; VVIQ imaging capacity, 2 levels; and mnemotechnic meihod, 4 levels) aud dependent variables immediate recail and delayed recall. AII three factors influenced recalí. Subsequent univariate analyses of variance indicated that subjects with high ST-PMA seore and subjects with high VVIQ score showed better immediate aud delayed tecalI ¡han subjects with low ST-PMA seore and subjects with low VVIQ score.

Los dos métodos tienen ventajas e inconvenientes. Recientemente se ha propuesto una alternativa que consiste en que sean compañeros de los sujetos los que elaboren las palabras clave, alternativa que parece eficaz. En esta investigación se deseaba saber si existía diferencia en el recuerdo inmediato y en el demorado cuando la palabra clave, reforzada con dibujos normales y raros, es elaborada por los experimentadores o cuando es elaborada por compañeros de los sujelos que participan en la investigación. También se deseaba saber si afectaba al recuerdo la capacidad de los sujetos de formar imágenes mentales cuando ésta se evalúa a través de cuestionarios y de pruebas espaciales. Se seleccionó una muestra de 377 estudiantes de ES...
The effectiveness of the mnemonic-keyword method was investigated in 4 experiments in which participants were required to learn the 1st-language (L1, Spanish) equivalents of a list of 30 2nd-language words (L2, Latin). Experiments 1 (adolescents) and 2 (adults) were designed to assess whether the keyword method was more effective than the rote method; the researcher supplied the keyword, and the participants were allowed to pace themselves through the list. Experiments 3 (adolescents) and 4 (adults) were similar to Experiments 1 and 2 except that the participants were also supplied with a drawing that illustrated the relationship between the keyword and the L1 target word. All the experiments were performed with groups of participants in their classrooms (i.e., not in a laboratory context). In all experiments, the rote method was significantly more effective than was the keyword method.
Aerobic fitness and related indices were evaluated in 254 soldiers at the beginning and near the end of initial army recruit training. Aerobic fitness in terms of maximal aerobic power was preidcted from the Astrand-Ryhming submaximal heart rate bicycle test. Estimated VO2 max increased by 8%, 42.0--45.3 ml/kg . min. Accompanying this increase in aerobic capacity was a decline in body fat content without a change in body weight. It is concluded that army recruit training at the time of this study was effective in terms of increasing aerobic work capacity and reducing excess body fat.
