Spatial Abilities Training in Anatomy Education: A Systematic Review

Spatial abilities have been correlated to anatomy knowledge assessment and spatial training has been found to improve spatial abilities in previous systematic reviews. The objective of this systematic review was to evaluate spatial abilities training in anatomy education. A literature search was done from inception to 3 August 2017 in Scopus^® and several databases on the EBSCOhost platform. Citations were reviewed and those involving anatomy education, an intervention, and a spatial abilities test were retained and the corresponding full-text articles were reviewed for inclusion. Before and after training studies, as well as comparative training programs, relating a spatial training intervention to spatial abilities were eligible. Of the 2,405 citations obtained, 52 articles were identified and reviewed, yielding eight eligible articles. Instruction in anatomy and mental rotations training were found to improve spatial abilities. For the seven studies retained for the meta-analysis that included the effect of interventions on spatial abilities test scores, the pooled treatment effect difference was 0.49 (95% CI [0.17; 0.82]; n = 11) improvement. For the two studies that included the practice effect on spatial abilities test scores in a control group, the pooled treatment effect difference was 0.47 (95% CI [−0.03; 0.97]; n = 2) improvement. In these two studies, the impact of the intervention on spatial abilities test scores was found despite the practice effect. Evidence was found for improvement of spatial abilities in anatomy education using instruction in anatomy and mental rotations training.     

Further evidence for a multifaceted model of mental speed: Factor structure and validity of computerized measures

The purpose of this study was to replicate the structure of mental speed and relations evidenced with fluid intelligence (Gf) found in a number of recent studies. Specifically, a battery of computerized tasks examined whether results with paper-and-pencil assessments held across different test media. Participants (N = 186) completed the battery, which incorporated 20 elementary cognitive tasks, 4 broad speediness (Gs) measures, and 5 Gf markers. Competing measurement models were tested. A higher-order model, with a general mental speed factor and 7 task-class specific factors fit the data well. Gs could not be distinguished from general mental speed. Besides the general mental speed factor, two task-class specific factors were moderately related to Gf. These findings strengthen the evidence for a multifacted structure of mental speed, and highlight the importance of specific speed task-classes in accounting for meaningful outcomes.     

Towards identifying dyslexia in Standard Indonesian: the development of a reading assessment battery

With its transparent orthography, Standard Indonesian is spoken by over 160 million inhabitants and is the primary language of instruction in education and the government in Indonesia. An assessment battery of reading and reading-related skills was developed as a starting point for the diagnosis of dyslexia in beginner learners. Founded on the International Dyslexia Association’s definition of dyslexia, the test battery comprises nine empirically motivated reading and reading-related tasks assessing word reading, pseudoword reading, arithmetic, rapid automatized naming, phoneme deletion, forward and backward digit span, verbal fluency, orthographic choice (spelling), and writing. The test was validated by computing the relationships between the outcomes on the reading-skills and reading-related measures by means of correlation and factor analyses. External variables, i.e., school grades and teacher ratings of the reading and learning abilities of individual students, were also utilized to provide evidence of its construct validity. Four variables were found to be significantly related with reading-skill measures: phonological awareness, rapid naming, spelling, and digit span. The current study on reading development in Standard Indonesian confirms findings from other languages with transparent orthographies and suggests a test battery including preliminary norm scores for screening and assessment of elementary school children learning to read Standard Indonesian.     

The Effect of Executive Function on Biological Reasoning in Young Children: An Individual Differences Study

There is substantial variance in the age at which children construct and deploy their first explicit theory of biology. This study tests the hypothesis that this variance is due, at least in part, to individual differences in their executive function (EF) abilities. A group of 79 boys and girls aged 5–7 years (with a mean age of 6½ years) were presented with two test batteries: (a) a biology battery that probed their understanding of life, death, and body functions and (b) an EF battery that tested working memory, inhibition, and set‐shifting skills. Individuals' EF scores significantly predict their biology scores, even after controlling for age and verbal IQ.     

The Influence of 16‐year‐old Students’ Gender,Mental Abilities,and Motivation on their Reading and Drawing Submicrorepresentations Achievements

Submicrorepresentations (SMRs) are a powerful tool for identifying misconceptions of chemical concepts and for generating proper mental models of chemical phenomena in students’ long‐term memory during chemical education. The main purpose of the study was to determine which independent variables (gender, formal reasoning abilities, visualization abilities, and intrinsic motivation for learning chemistry) have the maximum influence on students’ reading and drawing SMRs. A total of 386 secondary school students (aged 16.3 years) participated in the study. The instruments used in the study were: test of Chemical Knowledge, Test of Logical Thinking, two tests of visualization abilities Patterns and Rotations, and questionnaire on Intrinsic Motivation for Learning Science. The results show moderate, but statistically significant correlations between students’ intrinsic motivation, formal reasoning abilities and chemical knowledge at submicroscopic level based on reading and drawing SMRs. Visualization abilities are not statistically significantly correlated with students’ success on items that comprise reading or drawing SMRs. It can be also concluded that there is a statistically significant difference between male and female students in solving problems that include reading or drawing SMRs. Based on these statistical results and content analysis of the sample problems, several educational strategies can be implemented for students to develop adequate mental models of chemical concepts on all three levels of representations.     

Individual differences in speed of mental processing and human cognitive abilities: Toward a taxonomic model

Extensive research within the field of learning and individual differences focuses upon the relationship between general intelligence and process measures derived from elementary cognitive tasks (ECTs). This emphasis has ignored data indicating that cognitive abilities are best described by three levels (or strata). It has also been suggested that mental speed is a unitary construct, although it is more likely to have a complex structure. To address shortcomings evident in this literature, a multivariate investigation (N = 179) was conducted. Factor analysis of 25 psychometric indices gave seven factors postulated under the theory of fluid (G_f) and crystallized (G_c) intelligence. Correlations between cognitive abilities and parameters derived from 11 ECTs indicated that G_f (alone) was related to processing speed. This relationship is seemingly dependent upon experimental manipulations of task complexity. Regarding the factorial structure of mental speed, the results were unequivocal: Broad second-order factors may be derived from both ECTs and psychometric tests. These constructs are independent from abilities defined by accuracy scores and collectively define a general cognitive speed factor. Implications of these findings are discussed. It would appear that mental speed is more intricate than proposed, and that cognitive complexity (reflected in stimulus-response compatibility effects) plays a crucial role in its ontogenesis. In addition, several explanatory models linking intelligence to processing speed are untenable. It is likely that the search for a basic process of intelligence by means of mental speed frameworks (alone) is misguided.Recently, within the field of individual differences, there has been “an explosion of experimental studies into the speed of mental processes” (H.J. Eysenck 1995, p. 225). Various tasks, ranging from those paradigms assessing simple, psychomotor movements and on up through to measures of complex problem solving and psychometric test performance, have been employed (Stankov & Roberts 1997). The present study was designed to explore speed of processing constructs within a structural model of human cognitive abilities. Utilizing the evidence presented in Carroll's (1993) extensive reanalysis of the main data sets collected within the psychometric discipline this century, the structural model of cognitive abilities adopted is that known as the theory of fluid and crystallized intelligence (see Horn & Noll 1994; Stankov et al. 1995). In contrast, the mental speed measures selected for investigation in this study were chosen on the basis of both experimental and psychometric findings that rely on disparate accounts (e.g., information theory). Notably, mental speed constructs are not presently encapsulated within a single unifying model. Another major aim of the present study was to redress this imbalance by establishing a rapprochement between conceptual models of mental speed and human cognitive abilities.     

The influence of some parental characteristics on children's primary abilities and field independence: a study of adopted children.

The Children's Embedded Figures Test and measures of V, P, N and S abilities were administered to 5-7-year-old Belgian children (33 boys and 36 girls) adopted early in life. These child variables were correlated with the main factorial dimensions of the adoptive parents' answers on the Parental Attitude Research Instrument and on Buehler's Life Goals Inventory and with the adoptive mother's child-rearing practices, determined through an interview. The PARI dimensions were unrelated to children's test performances. Reinforcement of competition and independence, an interview variable, was significantly related to several ability measures and to the CEFT, especially in girls. The significant correlations of some LGI dimensions with boys' and/or girls' primary abilities were interpreted by referring to the influence on the development of children's abilities of a future-oriented attitude toward learning and memory and of a warm parent-child interaction.     

Empowering visuo-spatial ability in primary school: results from a follow-up study

The current study was primarily aimed at verifying the effect of a combined computer-assisted and pencil-and-paper training that was developed to empower visuo-spatial abilities in primary school pupils. One hundred and twenty third grade (mean average: eight years old) and fourth grade (mean age: nine years old) students attending several Italian primary schools were presented with several tests of the Primary Mental Abilities (PMA) battery by Thurstone and Thurstone. Of these, 64 children underwent the training “Recovery in visuo-spatial abilities” developed by Fastame and Antonini for 15 weekly sessions. The remaining students were assigned to the control group. Post-test scores and a follow-up assessment after six months by the end of the training highlight the positive impact of the intervention in enhancing visuo-spatial abilities.     

The factor structure and criterion validity of a test for assessment of cognitive abilities. Comparing students in special and regular education

As a consequence of a recent reform of junior secondary education in the Netherlands, instruments for the assessment of cognitive abilities of students who are eligible for special educational support must be designed. In constructing a new test battery contemporary theory on crystallized and fluid intelligence (Gf-Gc theory) was considered. Complete coverage of the factors in Gf-Gc theory was not striven for, because the status of some of these factors in relation to referral to education with special educational support is not entirely clear. The sample in the study consisted of students from regular and special primary as well as secondary education, aged between 11 and 15 years. Approximately two-thirds of the sample was of Dutch origin, whereas the remaining third was of a different ethnic origin. Results show that the factors verbal-crystallized ability, fluid-reasoning ability, spatial-visualization ability and memory capacity can explain the positive correlations between the tests in the battery for the greater part. Students from regular and special education can be distinguished on the basis of their cognitive profiles reasonably accurate, thus supporting the criterion validity of the test battery. Students requiring special educational support are characterized by a significant discrepancy between short-term recall and long-term retention and retrieval.     

Factor analysis of the metropolitan readiness test on first-grade children

The factor composition of the Metropolitan Readiness Test was investigated, using 1st-grade subjects in a suburban school district. In this analysis, a total battery score was supported, as well as a second factor believed to represent a language dimension of the test. None of the MRT's other content areas (auditory, visual, or quantitative abilities) or a distinct prereading measure were identified for this sample.     

The development of orthographic and phonological strategies for the decoding of words in children

This study examined the use of orthographic and phonological deletion strategies by children in the 6–16‐year age range. Children from Grades 1 to 10 (n=191) were presented either visually or orally isolated words and were asked to pronounce these words using either an orthographic (spelling) strategy following mental deletion of one letter, or a phonological (sounding) strategy following mental deletion of one sound. All children performed additional reading and spelling tasks in which they read and spelt all the words and derivatives from the deletion tasks. Analysis of variance revealed that younger readers were more accurate when using phonological strategies than when using orthographic strategies, whereas older readers showed superior orthographic and phonological processing abilities. Generally the results supported the suggestion that phonological and orthographic processing ability increase with age, and that the increase in these abilities with age is not solely dependent on reading and spelling ability.     

Family size,birth order,and intelligence in a large South American sample

The confluence theory, which hypothesizes a relationship between intellectual development birth order, and family size, was examined in a colombian study of more than 36,000 college applicants. The results of the study did not support the confluence theory. The confluence theory states that the intellectual development of a child is related to average mental age of the members of his family at the time of his birth. The mental age of the parents is always assigned a value of 30 and siblings are given scores equivalent to their chronological age at the birth of the subject. Therefore, the average mental age of family members for a 1st born child is 30, or 60 divided by 2. If a subject is born into a family consisting of 2 parents and a 6-year old sibling, the average mental age of family members tends, therefore, to decrease with each birth order. The hypothesis derived from the confluence theory states that there is a positive relationship between average mental age of a subject's family and the subject's performance on intelligence tests. In the Colombian study, data on family size, birth order and socioeconomic status was derived from college application forms. Intelligence test scores for each subject was obtained from college entrance exams. The mental age of each applicant's family at the time of the applicant's birth was calculated. Multiple correlation analysis and path analysis were used to assess the relationship. Results were 1) the test scores of subjects from families with 2,3,4, and 5 children were higher than test scores of the 1st born subjects; 2) the rank order of intelligence by family size was 3,4,5,2,6,1 instead of the hypothesized 1,2,3,4,5,6; and 3) only 1% of the variability in test scores was explained by the variables of birth order and family size. Further analysis indicated that socioeconomic status was a far more powerful explanatory variable than family size.     

Do you see what I mean? Shared reference in non-native, early signing deaf children

A group of non-native, early signing deaf children between the ages of 7 and 11 years were tested on a referential communication task. A group of hearing children matched for sex and mental and chronological age were also included in the study. The aim was to study the deaf children's ability to take another persons perspective in a task that resembled a real-life communicative situation to a higher extent than the standard theory of mind (ToM) tasks. A further aim was to investigate the possible importance of a number of background variables such as mental and chronological age, working memory, and false-belief attribution. Results show that the hearing children outperformed the deaf children on the referential communication task and that results were highly correlated with both chronological and mental age, as well as with working memory. There was a positive, but not significant, correlation between false belief and success on the referential communication task. This is an indication that the two tasks tap different abilities and that false belief might be necessary, but not sufficient in order to be skilled in the art of referential communication. The possible role of working memory in the referential communication task is also discussed. The results support the hypothesis of the importance of early talk about mental states for the later development of ToM abilities.     

The development of mental rotation abilities through robotics-based instruction: An experience mediated by gender

The research literature on the topic of “spatial ability” reveals that it has a major influence on achievement in the fields of science, technology, engineering and mathematics. Additionally, previous studies indicate the existence of a gender gap in spatial ability in favour of males. Mental rotation, one subskill of spatial ability, is an area in which gender differences are greater. At the same time, educational robotics is seen as one of the more promising technologies in educational contexts for the future. We conducted a quasi-experimental study with 142 seven- and eight-year-old students aimed at analysing whether robotics-based instruction may produce greater learning gains on mental rotation abilities compared to traditional instruction. The intervention was developed in the context of map-reading tasks, which are part of the curricular content in Mathematics and Social Sciences at this age. The results showed that for males, the robotics-based instruction promoted a significantly greater improvement in students’ mental rotation abilities compared to the control group. By contrast, no significant differences were observed for females. Although this study provides empirical evidence of the potential of robotics-based instruction, future studies need to deeply analyse the existence of gender differences in the learning gains obtained through educational robotics.     

Responsiveness-to-Intervention and School-Wide Positive Behavior Supports: Integration of Multi-Tiered System Approaches

Scientific reasoning of elementary age students with mild mental retardation was investigated using structured interviews during tasks involving properties of air and electricity. Discourse analysis was employed to describe preconceptions students with mild mental retardation reported about the natural world and how those preconceptions might be influenced by empirical evidence. Students in this investi- gation expressed prior understandings of air and electricity, but these understand- ings were incomplete and often at variance with generally accepted scientific fact. When faced with empirical evidence, students provided some responses that appeared to be more accommodating of this evidence. Characteristics such as outerdirectedness may have interacted with student responding. Implications for further research and practice are discussed.     

Longitudinal and Concurrent Relations among Temperament, Ability Estimation, and Injury Proneness

This study examined longitudinal and concurrent relations between temperament, ability estimation, and injury proneness. Longitudinal assessments of Inhibitory Control were collected through a behavioral battery at toddler (33 months) and preschool ages (46 months). Parent-reported measures of Inhibitory Control and Extraversion also were obtained at those ages. At school age (76 months), children participated in a set of tasks to assess overestimation and underestimation of physical abilities. Parents provided reports of children's temperament and injury history at school age. Results showed that children who were high on Extraversion and low on Inhibitory Control as toddlers and preschoolers tended to overestimate their physical abilities and to have more unintentional injuries at age 6. Children low on Extraversion and high on Inhibitory Control tended to underestimate their physical abilities. Implications for injury prevention are discussed.     

Longitudinal Prediction of Specific Cognitive Abilities from Infant Novelty Preference

A test of visual novelty preference, the Fagan Test of Infant Intelligence, was administered to a group of 113 full-term infants from the Colorado Adoption Project at 5 and 7 months of age. The infants were followed longitudinally and the Bayley scales were administered at 12 and 24 months, the Sequenced Inventory of Communication Development at 24 and 36 months, and the Stanford-Binet and the Colorado Specific Cognitive Abilities Test at 36 months. 1 novelty preference score was obtained for each infant by averaging across the 2 test ages. Novelty preference correlated significantly with 36-month Binet IQ, the first unrotated principle component from the cognitive battery, and the 24-month Bayley MDI score. Novelty preference was also compared to specific abilities at all 3 follow-up ages; all of the specific abilities were significantly related to novelty preference, with the exceptions of 12- and 24-month Imitation and 36-month Perceptual Speed. Partial correlations suggest that novelty preference predicts language and memory independent of IQ. Overall, the results indicate that novelty preference during the first year of life not only predicts later IQ but may also reflect specific cognitive processes.     

Language and literacy in nonvocal children with cerebral palsy

Metalinguistic and literacy abilities were studied in twenty-seven nonvocal cerebral palsied school children. The participants of the study were presented four tests of phonological awareness: rhyme recognition, sound identification, phoneme synthesis and word length analysis. Their verbal comprehension was measured using a semantic and a syntactic task. Two tests of nonverbal memory: the visual sequential task from ITPA and Corsi blocks and the Digit Span task from WISC, were also included. These measures were related to their reading and spelling ability. The nonvocal children performed on a lower level on the reading and spelling tasks than did the children of two comparison groups, one matched for mental age and one for mental and chronological age. There were no differences in phonological awareness or in verbal memory. The disabled children performed worse on the verbal comprehension task than the children in the comparison groups. Although the reading and spelling results were low in the nonvocal group there were children showing some literacy skills. A within-group analysis performed in the nonvocal group showed that the reading children performed better on all memory tests, and on the sound identification and the word length analysis tasks than the nonreading ones. They also showed better results on verbal comprehension, the semantic task and used more symbols in their communication. Synthetic speech was more often used in reading and spelling education in the reading subgroup than in the nonreading. Metalinguistic abilities and possibility of acoustic rehearsal are discussed as important factors in reading and spelling acquisition in the nonvocal population.

Psychological Assessment of High Ability: worldwide‐used Wechsler's intelligence scales and their psychometric shortcomings

Because the psychological assessment of high ability usually concentrates on intelligence testing, it is pertinent to discuss the validity of intelligence test batteries. The well‐known Wechsler's scales are analyzed and evaluated. Based on psychometric models, especially the Rasch model, analyses are made of some German editions, which show that hardly a single subtest scores fairly. That is, the true extent of testees’ abilities will not be correctly represented by the scores obtained under current scoring rules. Since many of the items of the analyzed editions correspond to items of the American edition (WISC‐R), the same shortcomings must also be suspect for that test battery. In this light, the administration of these tests is no longer acceptable. However, it is shown that Wechsler's basic concept is worthwhile when accompanied by (modern) psychometric tools: a new (German) test battery, AID, is introduced which, in particular, conforms to economic requirements if high ability is to be assessed.
