The impact of meaning and dimensionality on the accuracy of children's copying

Studies of intellectual realism have shown that children aged 7 to 9 copy a line drawing of a cube less accurately than a non‐object pattern composed of the same lines ( Phillips, Hobbs, & Pratt, 1978 ). However, it remains unclear whether performance is worse on the cube because it is a three‐dimensional representation, or because it is a meaningful object, or both. The accuracy with which twenty 7‐year‐old and twenty 9‐year‐old children reproduced 16 line drawings of two‐dimensional and three‐dimensional objects and non‐objects was assessed. Older children copied all types of drawing more accurately than younger participants, and children of all ages copied two‐dimensional drawings more accurately than three‐dimensional. Meaningfulness interacted with dimensionality for ratings of drawing accuracy, assisting the copying of two‐dimensional drawings, but having no impact on the copying of three‐dimensional drawings. For an objective measure based on position, length, and orientation of line, meaningfulness interacted with age group, being beneficial for 7‐ but not 9‐year‐olds. Overall, the results imply that, contrary to previous suggestions, meaningfulness can actually be beneficial to copying.     

Personality traits,gender differences and symptoms of anhedonia: What does the Hospital Anxiety and Depression Scale (HADS) measure in nonclinical settings?

In healthy populations men report more depressive symptoms than women when depression is measured by the Hospital Anxiety and Depression Scale (HADS). This study aims to investigate the role of neuroticism and extroversion in symptom reporting by men and women and whether anhedonia can explain these reversed gender differences in depression observed when using HADS. HADS, Positive and Negative Affect Schedule (PANAS) and NEO Five Factor Inventory (NEO FFI) were administered twice to a sample of university students. Number of subjects at T1 was 372 and 160 at T2, measured two months apart. Men had a higher average score on depressive symptoms measured by HADS‐D compared to women (p = 0.029). Women scored higher than men on HADS‐A (p = 0.012), neuroticism (p < 0.001) and PANAS‐negative affect (p < 0.029). No significant gender differences were observed in extroversion and positive affect. Test‐retest stabilities on HADS‐A and HADS‐D were high. Neuroticism predicted HADS‐A at Time 2. Gender, extroversion, and neuroticism predicted HADS‐D at Time 2. The anhedonic content in HADS may be a plausible explanation of reversed gender differences in the HADS depression scale. HADS‐D represents a specific anhedonic subtype of depression where symptom reporting reflects dispositional tendencies related specifically to extroversion.     

A PET meta‐analysis of object and spatial mental imagery

Neuroimaging studies have described the functional neuroanatomy of mental imagery. Taken separately, specific studies vary in the nature of the task used and are limited by statistical power and sensitivity. We took advantage of a multistudy PET database of 54 subjects acquired in our laboratory to reveal the neural bases of spatial versus object mental imagery tasks. Our first goal was to evaluate to what extent the activated foci elicited by both object and spatial studies overlap. A second aim was to compare activations elicited by spatial imagery tasks to those elicited by object imagery tasks. We also explored applying regression analyses to the relationships between the scores on the Mental Rotations Test (MRT) and changes in regional cerebral blood flow (rCBF) during spatial and object imagery tasks. This meta‐analysis yielded the following observations: (1) both spatial and object imagery tasks shared a common neural network composed of occipitotemporal (ventral pathway) and occipitoparietal (dorsal pathway) regions and also by a set of frontal regions (related to memory); (2) the superior parietal cortex was more strongly implicated during spatial imagery; (3) object imagery specifically engaged the anterior part of the ventral pathway, including the fusiform, parahippocampal, and hippocampal gyrus; (4) object imagery activated the early visual cortex, whereas spatial imagery induced a deactivation of the early visual cortex; (5) blood flow values in some of the regions noted above were positively correlated with scores on the MRT: the higher the subjects performed on the MRT, the more pronounced the rCBF was in these regions. These results may reconcile some of the apparent discrepancies among previous studies concerning the activation of early visual cortex in mental imagery. They also contribute to a better knowledge of the neural bases of object and spatial mental imagery.     

The Facts of Observation in Psychoanalysis

The regression of five achievement criteria on the six Metropolitan Readiness Test (MRT) subtests was determined for a sample of 100 Ss. The MRT was administered at the end of kindergarten, and the Gates-MacGinitie Reading Test and the arithmetic subtests of the Stanford Achievement Test were administered at the end of first grade. Results indicated that the MRT predicts first grade arithmetic better than it does reading and that Alphabet and Numbers are by far the best predictors among the six subtests of the MRT. A sex difference was present in that girls tended to earn higher scores than boys on the two reading criteria.

How Children Determine the Size of 3D Structures: Investigating Factors Influencing Strategy Choice

This study explores changes in students’ strategies as they solve different types of volume problems. Fifth graders were presented with pictures showing 3D objects and a unit cube; they determined how many cubes made up the object and explained their responses. We examined whether children transferred strategies across problem types, varying in terms of (a) availability of grids that divided objects into individual unit cubes, (b) order of items, (c) object shape, and (d) availability of the unit cube. Children's strategy choices varied systematically with object and task characteristics. They were more likely to use conceptually appropriate strategies when presented with grids. With non-gridded objects, they were more likely to treat a 3D object as a collection of 2D faces. Presenting gridded items first increased the use of conceptually appropriate strategies on the non-gridded items. We discuss findings in the context of Siegler's theory of strategy choice and address educational implications.     

The Role of Cognitive Flexibility in the Spatial Representation of Children's Drawings

Representing the spatial appearance of objects and scenes in drawings is a difficult task for young children in particular. In the present study, the relationship between spatial drawing and cognitive flexibility was investigated. Seven- to 11-year-olds (N = 60) were asked to copy a three-dimensional model in a drawing. The use of depth cues as an indicator of spatial drawing was examined. Furthermore, cognitive flexibility was assessed by three measures: the Wisconsin Card-Sorting Test 64 (reactive flexibility), the Five-Point Test (spontaneous flexibility), and omission/inclusion (representational flexibility). The results revealed significant relationships between all measures of flexibility and the depth cues in children's drawings. However, only spontaneous and representational flexibility turned out to be significant predictors of the spatial drawing score. The results are discussed in light of the specific requirements of spatial representations in drawings.     

The developmental trajectories of spatial skills in middle childhood

The multidimensional structure of spatial ability remains a debated issue. However, the developmental trajectories of spatial skills have yet to be investigated as a source of evidence within this debate. We tested the intrinsic versus extrinsic and static versus dynamic dimensions of the Uttal et al. (2013, Psychol. Bull., 139, 352) typology in relation to spatial development. Participants (N = 184) aged 6–11 completed spatial tasks chosen to measure these spatial dimensions. The results indicated that the developmental trajectories of intrinsic versus extrinsic skills differed significantly. Intrinsic skills improved more between 6 and 8 years, and 7 and 8 years, than extrinsic skills. Extrinsic skills increased more between 8 and 10 years than intrinsic skills. The trajectories of static versus dynamic skills did not differ significantly. The findings support the intrinsic versus extrinsic, but not the static versus dynamic dimension, of the Uttal et al. (2013, Psychol. Bull., 139, 352) typology.     

The developmental relations between spatial cognition and mathematics in primary school children

Spatial thinking is an important predictor of mathematics. However, existing data do not determine whether all spatial sub‐domains are equally important for mathematics outcomes nor whether mathematics–spatial associations vary through development. This study addresses these questions by exploring the developmental relations between mathematics and spatial skills in children aged 6–10 years (N = 155). We extend previous findings by assessing and comparing performance across Uttal et al.'s (2013), four spatial sub‐domains. Overall spatial skills explained 5%–14% of the variation across three mathematics performance measures (standardized mathematics skills, approximate number sense and number line estimation skills), beyond other known predictors of mathematics including vocabulary and gender. Spatial scaling (extrinsic‐static sub‐domain) was a significant predictor of all mathematics outcomes, across all ages, highlighting its importance for mathematics in middle childhood. Other spatial sub‐domains were differentially associated with mathematics in a task‐ and age‐dependent manner. Mental rotation (intrinsic‐dynamic skills) was a significant predictor of mathematics at 6 and 7 years only which suggests that at approximately 8 years of age there is a transition period regarding the spatial skills that are important for mathematics. Taken together, the results support the investigation of spatial training, particularly targeting spatial scaling, as a means of improving both spatial and mathematical thinking.     

Blind man draws using diminution in three dimensions

Can the principle of convergence in three spatial dimensions be reflected in drawings by the congenitally blind? A man who had been totally blind since birth was asked to draw scenes such as a tabletop with three cubes receding to the observer’s left side. He used converging lines to show the tops of the cubes receding in depth. He drew the cubes to the left smaller than the cube in front of the observer. He drew faces of cubes to the left with tilted lines, pointing to below the front face of the cube in front. The result approximates three-point perspective. We note that the directions of objects from a vantage point in touch converge much as they do in vision.     

Gender differences in patterns of spatial ability, environmental cognition, and math and English achievement in late adolescence

Relationships were explored among three measures of spatial ability--the Embedded Figures Test (EFT), the Mental Rotations Test (MRT), and the Differential Aptitude Spatial Relations subtest (DAT)--an environmental cognition task (MAP), American College Testing (ACT) math and English achievement, and gender in a sample of 282 undergraduates. Variance attributable to gender among the spatial tasks ranged from 0.5% in the EFT to 12% in the MRT. Gender accounted for only 1% of the variance in the MAP task. Gender differences were noted in regression analyses; women's math and English achievement scores were both predictive of spatial ability, while for men, only math achievement was predictive of spatial ability. The results were interpreted as substantiating sex role socialization theory of cognitive abilities.     

On the relationship between children's perspective taking in complex scenes and their spatial drawing ability

Depicting space and volume in drawings is challenging for young children in particular. It has been assumed that several cognitive skills may contribute to children's drawing. In the present study, we investigated the relationship between perspective‐taking skills in complex scenes and the spatial characteristics in drawings of 5‐ to 9‐year‐olds (N= 121). Perspective taking was assessed by two tasks: (a) a visual task similar to the three‐mountains task, in which the children had to select a three‐dimensional model that showed the view on a scene from particular perspective and (b) a spatial construction task, in which children had to plastically reconstruct a three‐dimensional scene as it would appear from a new point of view. In the drawing task, the children were asked to depict a three‐dimensional scene exactly as it looked like from their own point of view. Several spatial features in the drawings were coded. The results suggested that children's spatial drawing and their perspective‐taking skills were related. The axes system and the spatial relations between objects in the drawings in particular were predicted, beyond age, by certain measures of the two perspective‐taking tasks. The results are discussed in the light of particular demands that might underlay both perspective taking and spatial drawing.     

What Does Children's Spatial Language Reveal About Spatial Concepts? Evidence From the Use of Containment Expressions

Children's overextensions of spatial language are often taken to reveal spatial biases. However, it is unclear whether extension patterns should be attributed to children's overly general spatial concepts or to a narrower notion of conceptual similarity allowing metaphor‐like extensions. We describe a previously unnoticed extension of spatial expressions and use a novel method to determine its origins. English‐ and Greek‐speaking 4‐ and 5‐year‐olds used containment expressions (e.g., English into, Greek mesa) for events where an object moved into another object but extended such expressions to events where the object moved behind or under another object. The pattern emerged in adult speakers of both languages and also in speakers of 10 additional languages. We conclude that learners do not have an overly general concept of Containment. Nevertheless, children (and adults) perceive similarities across Containment and other types of spatial scenes, even when these similarities are obscured by the conventional forms of the language.     

Limits on efficient human mindreading: Convergence across Chinese adults and Semai children

We tested Apperly and Butterfill's (2009, Psychological Review, 116, 753) theory that humans have two mindreading systems whereby the efficient‐system guiding anticipatory glances displays signature limits that do not apply to the flexible system guiding verbal predictions. Experiments 1 and 2 tested urban Mainland‐Chinese adults (n = 64) and Experiment 3 tested Semai children living in the rainforests of Peninsular Malaysia (3‐ to 4‐year‐olds, n = 60). Participants – across different ages, groups and methods – anticipated others’ false‐beliefs about object‐location but not object‐identity. Convergence in signature limits signalled that the early‐developing efficient system involved minimal theory‐of‐mind. Chinese adults and older Semai children showed flexibility in their direct predictions. The flexible mindreading system in ascribing others’ beliefs as such was task‐sensitive and implicated maturational and cultural contributions.     

Investigation of Psychometric Properties of the Test for Creative Thinking—Drawing Production: Evidence from Study in Latvia

The Test for Creative Thinking—Drawing Production (TCT‐DP) is designed as an effective drawing‐based instrument for measuring creative potential. Many studies report adaptation efforts in other cultures pointing out good psychometric properties of the instrument nonetheless revealing also some trouble spots. The present study includes adaptation of TCT‐DP in Latvia and investigation of psychometric properties of the instrument such as measurement invariance between forms, sequence effect, gender differences, and factor structure of criteria employing methodology of structural equation modeling. Two samples were involved in the study—9th‐grade students (n = 300) and 15‐year‐old 9th‐grade students (n = 200). Results indicate that trained judges are able to achieve high reliability in evaluation of TCT‐DP total score and all criteria if some criteria are divided into subcategories. It was also found that TCT‐DP has measurement invariance between both forms but has small effect sizes regarding gender differences and method sequence. Observed differences of TCT‐DP total scores between the Latvian sample and relevant samples from Germany and Hong Kong could be considered as trivial. The study also revealed that, following original instructions, some test criteria had strong interdependence and therefore strategies in the evaluation process reducing interdependencies between criteria should be considered in future studies on the structure of TCT‐DP.     

‘It's not that we hate you’: Understanding children's gender attitudes and expectancies about peer relationships

Widespread gender segregation, evident throughout elementary school, seems to imply that girls and boys have negative feelings and thoughts about one another, and classic theories of inter‐group processes support this idea. However, research has generally overlooked children's feelings and perceptions about gender‐related interpersonal interactions. This paper investigates the nature of children's attitudes about same‐ and other‐gender peers, and explores how those attitudes relate to the expectancies and beliefs children hold about same‐ and other‐gender peer interactions. Children (N= 98 fifth graders) completed questionnaires assessing their global liking of own‐ and other‐gender peers ( Yee & Brown, 1994 ), positive and negative attitudes about own‐ and other‐gender peers, and outcome expectancies related to interacting with own‐ and other‐gender peers. Results indicated that rather than being characterized by out‐group negativity, children's inter‐group gender attitudes are best characterized by an in‐group positivity bias. Children's positive and negative affective attitudes were also significantly associated with outcome expectancies. In contrast, global liking of own‐ and other‐gender peers was less predictive of outcome expectancies. Thus, the greater specificity of the affective attitude measures appeared to be a more predictive and potentially fruitful gauge of children's feelings about own‐ and other‐gender peers. Results are discussed in terms of the need for finer grained and more extensive studies of children's gender‐related feelings and cognitions about own‐ and other‐gender peers.     

Gender differences in egalitarian behavior and attitudes in early childhood

It is axiomatic that human females are more egalitarian than males. However, surprisingly little empirical research exists that empirically assesses this stereotype. We created two studies designed to objectively examine egalitarian behavior in 3‐ to 5‐year‐old children. In Study 1 we compared the egalitarian behavior and attitudes of American girls versus boys by tabulating the extent to which each gender awarded the same number of stickers to, and liked to the same degree, two puppets. One puppet followed the child's instructions or actions while the other did not during a drawing task in which the child played the roles of leader and peer. In the peer role, girls exhibited more egalitarian behavior than boys. In Study 2, French‐Canadian children were shown two drawings by unknown peers—one messily and one neatly colored—, then asked to distribute stickers to each peer's drawing. Again, girls exhibited more egalitarian behavior than boys. Results suggest the origins of gender differences in egalitarian behavior occur early in life and merit further investigation.     

Developmental profiles for multiple object tracking and spatial memory: typically developing preschoolers and people with Williams syndrome

The ability to track moving objects, a crucial skill for mature performance on everyday spatial tasks, has been hypothesized to require a specialized mechanism that may be available in infancy (i.e. indexes). Consistent with the idea of specialization, our previous work showed that object tracking was more impaired than a matched spatial memory task in individuals with Williams syndrome (WS), a genetic disorder characterized by severe visuo‐spatial impairment. We now ask whether this unusual pattern of performance is a reflection of general immaturity or of true abnormality, possibly reflecting the atypical brain development in WS. To examine these two possibilities, we tested typically developing 3‐ and 4‐year‐olds and people with WS on multiple object tracking (MOT) and memory for static spatial location. The maximum number of objects that could be correctly tracked or remembered (estimated from the k‐statistic) showed similar developmental profiles in typically developing 3‐ and 4‐year‐old children, but the WS profile differed from either age group. People with WS could track more objects than 3‐year‐olds, and the same number as 4‐year‐olds, but they could remember the locations of more static objects than both 3‐ and 4‐year‐olds. Combining these data with those from our previous studies, we found that typically developing children show increases in the number of objects they can track or remember between the ages of 3 and 6, and these increases grow in parallel across the two tasks. In contrast, object tracking in older children and adults with WS remains at the level of 4‐year‐olds, whereas the ability to remember multiple locations of static objects develops further. As a whole, the evidence suggests that MOT and memory for static location develop in tandem typically, but not in WS. Atypical development of the parietal lobe in people with WS could play a causal role in the abnormal, uneven pattern of performance in WS. This interpretation is consistent with the idea that multiple object tracking engages different mechanisms from those involved in memory for static object location, and that the former can be particularly disrupted by atypical development.     

Associations of physical activity and gross motor skills with executive function in preschool children from low‐income South African settings

Executive function is foundational for cognitive development. Previous research has shown both gross motor skills and physical activity to be related to executive function. However, evidence for these relationships in the preschool years, as well as in low‐ and middle‐income countries is lacking. Therefore, this study aimed to investigate the relationships between components of executive function (inhibition, shifting and working memory) and gross motor skills (locomotor skills and object control skills) in a sample of preschool children from urban and rural low‐income settings in South Africa. Results revealed that inhibition and working memory, but not shifting, were associated with gross motor skills. More specifically: inhibition was associated with both locomotor [β = 0.20, p = 0.047] and object control skills [β = 0.24, p = 0.024], whereas working memory was only associated with locomotor skills [β = 0.21, p = 0.039]. Physical activity was not associated with inhibition and shifting but was negatively associated with working memory. These results elaborate a growing evidence base linking executive function and gross motor skills in the early years, and it is the first to look at specific associations of locomotor and object control skills with executive function in the South African context (a low‐ and middle‐income country).     

The relation between spatial and mathematical abilities: Potential factors underlying suppression

Two experiments examined possible factors underlying the finding that grades in mathematics act as a suppressor variable in the relation between spatial abilities and gender. Specifically, the role of reading abilities was investigated in Experiment 1 by using English grades as a measure of these abilities. Experiment 2 was based on the notion that time pressures are involved at some level in both spatial performance and mathematics grades. The influence of this factor was examined by administering a spatial task with or without time limit and examining the suppression effect in both conditions. In both experiments, participants completed the Mental Rotations Test (MRT) as a measure of spatial ability. In Experiment 1, all participants were tested with limited time to complete the MRT and they were required to report their high school course grades in mathematics and English. Results revealed that both grades in high school mathematics and English produced significant suppression. However, the amount of suppression produced by each measure was similar. Therefore, the prediction that suppression would be greater with English than with mathematics grades was not supported. Experiment 2 involved testing in groups or individually with or without time limits on the MRT, whereas the Water Level Test was administered untimed, and only grades in mathematics were obtained from participants. Results supported the prediction that the suppression effect is greater when time limits are applied than when they are not. Implications of the results for an explanation of the observed suppression are discussed. Emphasis is placed on the difficulties inherent to the identification of factors underlying suppression.
