Main Effects

A sample of 111 first-grade children was partitioned into 4 categories, where the categorization was determined by an ability to make quantitative comparisons and IQ. 6 problems of each of 8 problem types were presented to each child in a randomized sequence. Approximately one-half of the children in each category were randomly assigned to 1 of 2 levels of Problem Conditions. A multivariate analysis of variance indicated that IQ was not significant. Problem Conditions was significant (p<.01p<.01). Univariate analysis indicated a significant interaction (p<.05p<.05) due to Quantitative Comparisons and Problem Conditions for 1 problem type; significant main effects (p<.01p<.01) due to Problem Conditions for the remaining 7 problem types; and a significant (p<.05p<.05) main effect due to Quantitative Comparisons for 1 of the remaining 7 problem types.

The performance of Black grandparents was examined to determine the most suitable content for an educational program intended to assist them in their role. A sample of 626 non-consanguineous subjects included 204 grandparents, 128 parents, and 294 grandchildren. Each generation group completed a separate version of the Grandparent Strengths and Needs Inventory to identify the favorable qualities of grandparents and aspects of their relationships in which further growth was necessary. A combination of multivariate analysis of variance procedures, univariate analysis of variance tests, and t-tests were used to analyze scores, confirm results, and assist with interpretation of data. All groups described aspects of grandparents success and made known specific realms of learning that grandparents should acquire in order to become more effective. Analysis of the responses revealed significant main effects for generation, gender of grandchild, age of grandchild, and amount of time that grandparent and grandchild spent together. Considerations were identified for improving grandparent influence and guiding the development of grandparent education programs.

The purpose of this study was to compare the coping strategies between homeless women with dependent children and homeless women without dependent children. Of the 192 homeless women in this study, 64 were mothers whose dependent children lived with them, and 132 were women who did not have dependent children living with them. The women were recruited from homeless shelters in Georgia, in the Metro Atlanta area and surrounding counties. Multivariate analysis of variance (MANOVA) was used to test the differences between both groups using their scores on the Coping Strategies Inventory scales survey instrument (problem-solving skills, problem reframing, and ability to access social networks). Univariate analysis was used to look at each dependent variable. There was no statistical difference in coping strategies between both groups. The conclusions from this study suggest continued research regarding the benefit of coping strategies among homeless populations.

Anxiety Levels

Interactions of attention and verbalization were investigated for effects of self-reported arousal and state-anxiety. Levels of verbalization from silence through talking-without-a-listener to disclosure were compared while self-directed attention was manipulated for sensation versus general thoughts and feelings. Following a stimulus, disclosure of sensations was expected to reduce state anxiety and increase energetic arousal significantly more than disclosure of thoughts. Based on a randomly assigned sample of 120 men, a 3 × 2 × 2 multivariate analysis of variance indicated a significant interaction in the predicted directions. A significant interaction was also found for the 3 × 2 interaction for energetic arousal. For state anxiety means were in the predicted direction. Results indicate that verbalization of sensations is more energizing and calming than silence, while for general thought, silence is more energizing and calming than verbalization. The results suggest efficacy in reframing self-talk to quiet awareness and in communicating sensed distinctions as they emerge.

320 Croatian female students ( M = 20.4 yr.) were recruited to examine the validity and reliability of figural scales using different numbers of stimuli (3, 5, 7, and 9) and different serial presentation (serial and nonserial order). A two-way analysis of variance (4 numbers × 2 orders of stimuli) was performed on ratings of current self-size and ideal size as dependent variables. Analysis indicated a significant main effect of number of stimuli. This, together with post hoc tests indicated that ratings were significantly different for a scale of three figures from scales of more figures, which in turn did not differ among themselves. Main effects of order of stimuli, as well as the interaction, were not significant. The results support the hypothesis that the optimal number of figures on a scale is seven plus (or minus) two.

Repeated Measures Designs

Violation of the sphericity assumption in repeated-measures analysis of variance can lead to positively biased tests, i.e., the likelihood of a Type I error exceeds the alpha level set by the user. Two widely applicable solutions exist, the use of an epsilon-corrected univariate analysis of variance or the use of a multivariate analysis of variance. It is argued that the latter method offers advantages over the former.

The aim of this study is to compare the motor skills status of girls with different nutritional status. The research sample consisted of 180 girls aged 10 and was divided into 4 subsamples: malnourished, normally nourished, pre-obese and obese girls. The assessment of the motor space was carried out with a battery of eighteen motor tests. The identification of the differences between the groups was carried out by the Univariate Analysis of Variance (ANOVA) method. The significance of the differences between the groups was tested by the Multivariate Analysis of Variance (MANOVA) method. The results of the study suggest that obese girls had problems in variables which assessed the explosive power of the lower extremities, running speed and repetitive strength. No significant differences were found for variables which evaluate segmental speed, flexibility, precision, balance, cranial body muscle explosion, and coordination.

Diagnostic Traits

In the Turkish flora, the genus Matricaria is present with four taxa, namely M. aurea, M. chamomilla var. chamomilla, M. chamomilla var. recutita and M. matricarioides. This study presents an evaluation of selected diagnostic characters and anatomical traits of the achene (cypsela) of Matricaria in Turkey using univariate analysis (one-way analysis of variance) and multivariate analysis (cluster analysis, principal component analysis) to obtain new information. Three groups are found within the genus Matricaria based on morphoanatomical characteristics. The colour of disc florets, that of ribs on the achenes, the presence or absence of a slime envelope and pericarp thickness are useful for delimitation of Matricaria taxa, and a key to taxa based on these characters together with other diagnostic traits is provided.

Background: High-speed drumming requires precise control over the timing, velocity, and magnitude of striking movements. Aim: To examine effects of tempo and expertise on unaccented repetitive drumming performance using 3D motion capture. Methods: Expert and amateur drummers performed unimanual, unaccented, repetitive drum strikes, using their dominant right hand, at five different tempi. Performance was examined with regard to timing variability, striking velocity variability, the ability to match the prescribed tempo, and additional variables. Results: Permutated multivariate analysis of variance (PERMANOVA) revealed significant main effects of tempo (p < .001) and expertise (p <.001) on timing variability and striking velocity variability; low timing variability and low striking velocity variability were associated with low/medium tempo as well as with increased expertise. Individually, improved precision appeared across an optimum tempo range. Precision was poorest at maximum tempo (400 hits per minute) for precision variables. Conclusions: Expert drummers demonstrated greater precision and consistency than amateurs. Findings indicate an optimum tempo range that extends with increased expertise.
