Internal consistency and construct validity of two versions of the Revised Vividness of Visual Imagery Questionnaire

The Vividness of Visual Imagery Questionnaire (VVIQ; Marks, 1973) is the questionnaire most extensively used to measure imagery vividness, but two newer versions have been developed. In this study, the reliability and construct validity of these two measures were assessed: the Vividness of Visual Imagery Questionnaire-2 (VVIQ-2) and the Vividness of Visual Imagery Questionnaire-Revised Version (VVIQ-RV). A total of 206 undergraduate psychology students completed both questionnaires, and to assess construct validity, they also completed the Object-Spatial Imagery and Verbal Questionnaire (OSIVQ), Betts' Questionnaire Upon Mental Imagery (Betts' QMI), and the Measure of Ability to Form Spatial Mental Imagery (MASMI). Internal consistency reliability for both was high, with the VVIQ-RV having a Cronbach's alpha of .96, and the VVIQ-2 an alpha of .91. The construct validity of the VVIQ-RV and the VVIQ-2 was supported by the high correlations they had with the other three measures of imagery, which were all close to .50, and the very small correlations (.06-.07) they had with the Verbal scale of the OSIVQ, indicating that they validly measured the imagery construct. Thus, the findings support the two versions as equally valid psychometric instruments for measuring image vividness.     

The Spanish version of Betts' Questionnaire Upon Mental Imagery

Sheehan's shortened form of Betts' Questionnaire Upon Mental Imagery is one of the most widely used inventories for measuring imaging. Participants were 562 undergraduate students (414 women and 148 men), with a mean age of 20.2 yr. In a principal components analysis followed by varimax orthogonal rotation for the Spanish version, eight factors were identified, six of which coincide with those of the original English version. Internal consistency was .92 (Cronbach alpha). Scores on the Betts Questionnaire Upon Mental Imagery correlated -.34 with those on the Gordon Test of Visual Imagery Control, .58 with those on the Vividness of Visual Imagery Questionnaire, and .02 with the Verbalizer-Visualizer Questionnaire.     

Some psychometric properties of the Spanish version of the Clarity of Auditory Imagery Scale

Few tests have been designed to measure auditory imagery. This study assessed the factor structure and internal consistency of the Spanish version of the Clarity of Auditory Imagery Scale (CAIS). Participants were 234 undergraduate students (M age = 19.6 yr.). Internal consistency reliability estimated by Cronbach's alpha was .82. In a principal components analysis followed by varimax orthogonal rotation, five factors were identified. Scores correlated moderately and positively with ratings on the Vividness of Visual Imagery Questionnaire-2 and negatively on the auditory scale of Betts' Questionnaire Upon Mental Imagery, but weakly and negatively with scores on the Measure of the Ability to Form Spatial Mental Imagery.     

The Spanish version of the Vividness of Visual Imagery Questionnaire: factor structure and internal consistency reliability

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.

An inquiry into the construct validity of the Vividness of Visual Imagery Questionnaire

The construct validity of the Vividness of Visual Imagery Questionnaire (VVIQ) was investigated using a series of visual memory tasks. Subjects were shown a picture after completing the questionnaire. Their ability to recall that picture was probed through a free-recall procedure, drawing, two spatial-recall tasks, and a multiple-choice questionnaire. Scores on the VVIQ were statistically unrelated to performance on any of the memory tasks demonstrating a lack of support for construct validity as a measure of visual memory imagery.     

Apparent equivalence between perception and imagery in the production of various visual illusions

The ability of high and low imagers (as assessed by the Vividness of Visual Imagery Questionnaire) to utilize imagery in the production of a visual illusion was examined in three experiments. In Experiment 1, subjects were to imagine noninducing elements oi the Ponzo figure. In Experiment 2, subjects were asked to imagine the inducing angle of the Ponzo figure. Subjects were requested to imagine the inducing diagonals of the Hering and Wundt figures in Experiment 3. Regardless of which figure was presented, high imagers consistently reported an illusion whether it was produced by real or imagined lines. Also, the imagery-produced illusion was equivalent in magnitude to the actual illusion (when all lines are physically present). Low imagers reported an illusion only when lines were physically present. These results were interpreted in terms of Finke’s (1980) equivalence theory.     

A questionable questionnaire: a rejoinder to Marks

In a recent article Marks argues that two previous articles in this journal in 1986 and 1988, questioning the construct validity of the Vividness of Visual Imagery Questionnaire, should be dismissed due to methodological flaws and overwhelming evidence to the contrary. In this response to Marks, the methodologies of the two studies in question are clarified and defended. Research and other evidence supporting the two Chara studies are presented. It is concluded that the construct validity of the imagery questionnaire has not been established and that further investigations of the questionnaire, and particularly its rating scale, are warranted.     

Individual differences in reported visual imagery and cognitive performance

Selected on the basis of their scores on the Vividness of Visual Imagery Questionnaire, 16 High Visualizers and 14 Low Visualizers (equally divided by sex) completed various cognitive tasks thought to involve visual (Space Relations, Watch Rotation) and non-visual (Verbal Reasoning, Abstract Reasoning, Numerical Ability) processes. Although Low Visualizers (particularly males) were superior to High Visualizers in Numerical Ability, both groups performed equally well on the other tests. Since correlational analyses indicated that scores on the vividness questionnaire and the Gordon Controllability of Imagery Questionnaire were not independent, particularly for females, it was suggested that questionnaires ought to be developed better to differentiate the abilities to generate and control visual images.     

Psychometric properties of the Spanish version of the Flow State Scale

The purpose of this research was to examine the psychometric properties of a Spanish translation of the Flow State Scale (FSS; Jackson & Marsh, 1996). This instrument is used to assess the Flow State in participants of physical activity, although it can be adapted to other contexts (such as work, educational contexts, etc.). This construct can be considered the optimal psychological state to carry out an activity, being closely related to motivation and personal enjoyment (Csikszentmihalyi, 1997). A sample of 2036 athletes was recruited from diverse sports activities. The results revealed satisfactory validity and internal consistency of the instrument, obtaining a factor model made up of a main factor and nine subscales. The correlations between motivational orientations and the flow state are highlighted. The Spanish translation of this instrument is found to be acceptable, with similar psychometric properties as the original scale, although future research in other contexts is needed to support these outcomes.     

The Role of Vividness of Visual Mental Imagery on Different Dimensions of Creativity

Although research demonstrated that people can mentally manipulate and synthesize visual elements into a creative object, the role that vividness of visual imagery plays on creative imagery is still unclear. This study explored the relationships between vividness of visual imagery and 3 dimensions of creative imagery: originality, practicality, and mental spatial transformations of visual elements. Fifty-three participants performed the creative mental synthesis task and completed the Vividness of Visual Imagery Questionnaire (VVIQ). Results revealed a positive relationship between vividness and the practicality dimension of objects. No relationship was found either between vividness and originality or between vividness and transformational complexity. The association vividness–practicality seems to reflect the ability to use pictorial information of imagery when people generate functional objects that belong to specific categories. Future research directions are discussed.     

Individual differences in reported visual imagery and memory performance.

Seventy high school students completed the Vividness of Visual Imagery Questionnaire (VVIQ). Two months later, the 16 highest scores (low visualizers) and the 16 lowest scores (high visualizers) took part in a memory experiment involving abstract words, concrete words and pictures. Analyses of variance showed that high visualizers were superior to low visualizers on all three kinds of item in short-term recall, whereas they were only superior on the concrete words and pictures in long-term recall. Finally, both groups performed equally well on a subsequent recognition test. The results were interpreted as providing support for the validity of the VVIQ.     

Construct validity of the Vividness of Visual Imagery Questionnaire

Chara (1989) recently questioned the construct validity of the Vividness of Visual Imagery Questionnaire (VVIQ) on empirical grounds. Unfortunately, Chara in that paper has erroneously construed construct validity as independent of criterion-related validity. This error is compounded by Chara and Verplanck's 1986 assumption that the VVIQ assesses purely memory imagery. Further problems arise from Chara's 1989 selective reporting of the relevant literature. Comprehensive review of the VVIQ literature in its totality is necessary before conclusions are possible concerning the questionnaire's construct validity.     

Effects of instructions and format on reported visual imagery

156 subjects (students and working adults) completed Marks' Vividness of Visual Imagery Questionnaire in one of two formats reflecting item order (blocked, random) under one of three instructional conditions (easy, neutral, difficult) reflecting ease of image formation. Although the effect of instructions (but not format) was significant, scores were lower, i.e., more vivid imagery was reported, in the easy than in the neutral or difficult conditions, which did not differ. These results suggest that the validity of Marks' questionnaire is not seriously weakened by response leniency.     

Parental imagery vividness: gender differences and relationships to emotional closeness

This research was an investigation of the vividness with which individuals see their parents in different situations. In 3 studies, the Vividness of Visual Imagery for Parents Questionnaire (VVIPQ; S. J. McKelvie, 1998a) was completed by university undergraduates (201 women, 167 men). Visual imagery of mothers was reported to be more vivid than that of fathers, but only by the female students. For intact families, the female students also reported more imagery of mothers than of fathers, whereas the male students reported more vivid imagery of fathers than of mothers. However, for divorced or separated families in which individuals spent more time with their mothers, both men and women rated their mothers more vividly than their fathers. More vivid imagery was positively related to reported emotional closeness to parents and to more vivid imagery for general scenes. VVIPQ scores were associated with social desirability but were not related to measures of response leniency or general intelligence. Split-half reliability of the VVIPQ was very good, and both test-retest and alternate-format reliability were acceptable. The correlational evidence supports the construct validity of the VVIPQ, which is a promising tool for studying parental imagery.     

Influence of Training in Artistic Skills on Mental Imaging Capacity

ABSTRACT

Artistic creation often involves the use of mental images. This investigation examined the influence of training in artistic skills on mental imaging capacity in a sample of 126 subjects aged between 18 and 23 years. First- and 5th-year fine arts students were compared with regard to their performance in 2 imaging capacity tests (the Visual Elaboration Scale and the Vividness of Visual Imagery Test) and 3 tests of drawing involving spatial representation, transformation of spatial relations, and memory. The students who had undergone a longer period of artistic training performed significantly better on all 5 tests, and all drawing tasks scores correlated with each other. These results indicate that artistic training may enhance imaging capacity.     

The Relationship between Imagery Ability and Imagery Use among Athletes

The present study aimed to provide a better understanding of the relationship between imagery ability and imagery use. Athletes completed the Movement Imagery Questionnaire—Revised Second Version, the Motivational Imagery Ability Measure for Sport, and the Sport Imagery Questionnaire. Hierarchical regression analyses revealed that imagery ability explained 20 to 41% of the variance in the use of the functions of imagery. Visual and kinesthetic imagery ability predicted cognitive specific imagery use; motivational general-mastery and motivational general-arousal imagery ability predicted the use of the motivational general functions of imagery. To assess imagery ability multiple methods of assessment must be used.     

Preliminary validation of a Spanish language version of the Adoption Communication Scale in adopted adolescents / Validación preliminar de una versión en español de la escala Adoption Communication Scale para adolescentes adoptados

Abstract

The Adoption Communication Scale (ACS) is a 28-item child-report instrument used to assess adoptees’ perception of communication openness in the family. The aim was to develop a Spanish language version of the scale (ACS-S) and to assess the instrument’s psychometric properties in a sample of 55 adopted adolescents. The ACS-S was found to have high internal consistency (α = .93) and moderately high test-retest stability (.68). An exploratory factorial analysis yielded two factors, the first loaded on satisfaction with emotional communication items and the second encompassing satisfaction with the completeness of the information offered by the parents. These factors are coherent with the theory underlying the scale. The total ACS-S score was significantly positively correlated with adolescent Global Satisfaction with Openness as measured by a Visual Analogue Scale. The ACS-S scale appears to be a valid tool in assessing communication openness in Spanish adopted adolescents.     

Self-rated imagery and encoding strategies in visual memory.

The value of self-rated vividness of imagery in predicting performance was investigated, taking into account the mnemonic strategies utilized among subjects performing a visual-memory task. Subjects classified as 'good' or 'poor' imagers, according to their scores in the Vividness of Visual Imagery Questionnaire (VVIQ; Marks, 1972), were to detect as rapidly as possible differences between pairs of similar pictures presented consecutively. No coding instructions were given and the mnemonic strategies used were analysed by studying subjective reports and objective performance measurements. The results indicated that the subjects utilized two main strategies--a detail or an image strategy. The detail strategy was the more efficient. In accordance with a previous study (Berger & Gaunitz, 1977), it was found that the VVIQ did not discriminate between performance by 'good' and 'poor' imagers. However, among subjects who used the image strategy, 'good' imagers performed more rapidly than 'poor' imagers. Self-rated imagery may then have some value in predicting performance among individuals shown to have utilized an image strategy.
