Young Children's Awareness of Their Mental Activity: The Case of Mental Rotation

From Piaget's early work to current theory of mind research, young children have been characterized as having little or no awareness of their mental activity. This conclusion was reexamined by assessing children's conscious access to visual imagery. Four-year-olds, 6-year-olds, and adults were given a mental rotation task in the form of a computer game, but with no instructions to use mental rotation and no other references to mental activity. During the task, participants were asked to explain how they made their judgments. Reaction time patterns and verbal reports revealed that 6-year-olds were comparable to adults both in their spontaneous use and subjective awareness of mental rotation. Four-year-olds who referred to mental activity to explain their performance had reaction time and error patterns consistent with mental rotation; 4-year-olds who did not refer to mental activity responded randomly. A second study with 5-year-olds produced similar results. This research demonstrates that conscious access to at least 1 type of thinking is present earlier than previously recognized. It also helps to clarify the conditions under which young children will and will not notice and report their mental activity. These findings have implications for competing accounts of children's developing understanding of the mind and for the "imagery debate."     

Epistemological resources for thought experimentation in science learning

Thought Experiments (TEs) are reasoning processes that are based on 'results' of an experiment carried out in thought. What is the validity of an experiment- that has not been actually executed- for knowledge about the physical world? What are the features that make it distinctive and how do we integrate it into learning environments to support such thought processes? This study suggests that a thought experiment draws on three epistemological resources: conceptual-logical inferences, visual imagery and bodily-motor experience. We start by stating how students' TEs are related to recent research on learning science and then proceed to describe the nature of TEs. The central part of the paper deals with cognitive theories and empirical examples of visual imagery and bodily imagery. It also deals with how these enable implicit knowledge about the world to be retrieved. Students may have, but are not aware of, such knowledge for it is hidden when learning is only based on formal representations. We show that imagination is structured, goal-oriented, based on prior experiential imagery and internally coherent. Students can, for example, mentally rotate objects at constant velocity. Students can 'zoom in and out' to inspect imaginary situations, transfer objects, predict paths of imaginary moving objects and imagine the impact of forces on mechanical systems. We show that the TEs are powerful because of these capabilities. We further claim that these are not exploited by school learning environments and offer a first step towards understanding imagery in science learning.

Verbal and visual learning styles

Three studies are reported concerning the development of a questionnaire to assess verbal and visual learning styles. The test instrument is based upon Richardson's Verbalizer-Visualizer Questionnaire (VVQ). In the first study, it is shown that the VVQ requires more than a single bipolar dimension, and that when two dimensions are extracted, the hypothesized visual dimension is defined mainly by dream vividness and is not related to self-reported mental imagery. In the second study, an expanded questionnaire is constructed to assess the verbal and dream dimensions located in the first study, as well as a visual dimension more related to mental imagery. Both the verbal and visual scales are designed to be more relevant to preferences in learning. The three scales are shown to possess adequate reliability and construct validity. In the third study, the correlations of the three scales with various mental abilities are explored: as hypothesized, the verbal learning style is most strongly correlated with verbal ability and the visual learning style with spatial visualization. Possible directions for future research are discussed: further validation of the three scales, investigation of the development of learning styles, and the use of the style scales in studies of learning.

出仕与归隐--陶渊明诗歌的飞鸟意象及其审美内蕴

鸟是具有一定象征意义的对象物,它的象征内涵是经过长期积淀的.先民视野中的鸟开启了后代诗文中鸟的“原型意象“,归纳起来,大概分为两类:一是追求宏大的境界,是经过拼搏后的自由;一是选择退守,是疏离群体的个体自由.这两种“原型意象“陶渊明诗中兼而有之,可以看作是其人生转换的前后标志.而陶渊明思想转变可以从飞鸟意象中得到证实.     

Mental Preparation Strategies of Olympic Archers During Competition: an exploratory investigation

Extensive interviews were conducted with all eight members of the 1996 Italian Olympic archery team regarding psychological factors associated with excellence and mental preparation strategies adopted during competition. Hierarchical inductive analysis revealed that positive expectations, concentration, facilitating emotions, body awareness and technical preparation were the mental aspects described by archers necessary for effective performance. Furthermore, the archers outlined a variety of mental preparation strategies including (a) autonomic control (emotion control, somatic control, internal dialogue, and focus on shooting), (b) imagery (visualization, self‐talk), (c) task‐focused concentration (body and action control, thought control) and (d) reaction to mistake (focus on correct execution, mistake disregard, shooting analysis). The idiosyncratic nature of the athlete's competition strategies highlights the need of gaining information about the particular demands of the sport and the mental procedures spontaneously developed by the performer, to provide suitable counselling or psychological intervention.     

Performance on Middle School Geometry Problems With Geometry Clues Matched to Three Different Cognitive Styles

ABSTRACT— This study investigated the relationship between 3 ability‐based cognitive styles (verbal deductive, spatial imagery, and object imagery) and performance on geometry problems that provided different types of clues. The purpose was to determine whether students with a specific cognitive style outperformed other students, when the geometry problems provided clues compatible with their cognitive style. Students were identified as having a particular cognitive style when they scored equal to or above the median on the measure assessing this ability. A geometry test was developed in which each problem could be solved on the basis of verbal reasoning clues (matching verbal deductive cognitive style), mental rotation clues (matching spatial imagery cognitive style), or shape memory clues (matching object imagery cognitive style). Straightforward cognitive style–clue‐compatibility relationships were not supported. Instead, for the geometry problems with either mental rotation or shape memory clues, students with a combination of both verbal and spatial cognitive styles tended to do the best. For the problems with verbal reasoning clues, students with either a verbal or a spatial cognitive style did well, with each cognitive style contributing separately to success. Thus, both spatial imagery and verbal deductive cognitive styles were important for solving geometry problems, whereas object imagery was not. For girls, a spatial imagery cognitive style was advantageous for geometry problem solving, regardless of type of clues provided.     

Individual Differences in Thinking: cognitive and neurophysiological perspectives

This paper explores the neglected area of categories of individual difference in human cerebral function. During thinking and decision making, it is hypothesised that different people process the same information in different ways, using different areas of the brain. Recent work suggests that individuals can be categorised into a small number of consistent groups of thinking, or cognitive, style. The different ways of processing reflect two basic dimensions of cognitive style. A simple computer‐presented method of determining cognitive style has been developed.

It is probable that these styles have an underlying cerebral basis. The styles are likely to be related to cerebral orientation. The specialisation of one cerebral hemisphere for verbal function and the other for visuo‐spatial has been long established. Hemispheric specialisation has been associated with the right hemisphere being the location of the visuo‐spatial and the left the verbal function, although evidence for this has been sometimes conflicting. This is not surprising when attention has not been paid to individual differences in cognitive style, as subjects of different styles will use different processes when doing the same cognitive task. Individual differences in orientation have not been clearly linked to differences in cognitive style.

It is proposed that studies could usefully explore the cerebral basis of individual differences in cognitive style, by measuring EEG asymmetries of individuals of specific cognitive styles, during the performance of a range of cognitive tasks. It is proposed that this would identify the location of certain brain functions associated with the different processing underlying the styles. A subsidiary intention is to assess the effectiveness of digital EEG monitoring as a research tool in this context.     

The Context of Thought Experiments in Physics Learning

This paper takes a cognitive perspective in an attempt to analyze mental mechanisms involved in contextual learning. In the following, it is suggested that contextualized environments evoke mental mechanisms that support reasoning about what if, imaginary situations – utilizing a powerful mental mechanism known from the history of physics as thought experiments (TEs). Thought experiments are associated with visualization of data and imagery that originate in implicit knowledge. This paper suggests that thought experiments rely on sensory memories constructed by the learner during past experience. Such sensory memories are activated by the context. The first part of the paper deals with the definition, nature, incidents, and experimental data related to implicit knowledge and TEs. Empirical results are then analyzed in order to explore the role of sensory memories and underlying schemata in TEs, thereby suggesting a set of embodied schemata that act as implicit assumptions and provide context-dependent epistemological primitives that underlie imaginary events in a manner that will statistically match the outer world.     

Making and Mistaking Reality: What is Emotional Education?

A central thesis of this paper is that the mind and its thought evolve out of the experience of the whole person in their unique surroundings. It attempts to articulate the meaning and value of Emotional Education, especially in its relation to thought processes. It shows the value of learning from the particular, and from awareness of feeling states. It shows how making emotional enquiry can change the nature of the thinking, reducing the need of the thinker, and involves experiencing while not-knowing as well as more usual rational approaches.Recent affirmations from neuroscience of the psychoanalytic picture of conscious awareness arising from unconscious emotional processes are noted. Systemic and emotional thought processes are described and illustrated.While the nature of unconscious choice is recognised as part of all thought process, the “use of self” is explored as a conscious means of influencing the nature of thinking, and the attributes of both person and context necessary to flourishing thought are contrasted with the human needs which produce mistaken thought. Some questions which have been asked by students in Emotional Education classes, about free will, abuse, and ethics are raised. I hope the gratitude to people who have shared their feelings in order to think and be thought about in “emotional thinking” is evident; it is very real to me.

CREATIVE PROCESSES IN SCIENTIFIC DISCOVERY

At present, computational models of scientific discovery and theory formation play a prominent role in illuminating transformations of rational conceptual systems. A new abstraction paradigm aimed at unifying the different perspectives and providing insight for future ones is proposed here. The aim is to emphasize the significance of “abduction” in order to propose a unified epistemological model of scientific discovery. This model first describes four meanings of the word abduction (creative, selective, visual, inference to the best explanation) in order to clarify their significance in epistemology and “Artificial Intelligence” (AI). Among the different abductive roles played by various kinds of conceptual transformations in developing scientific creative reasoning–such as radical ontological change, conceptual combination, analogical and visual thinking, anomaly resolution, thought experiment — visual mental imagery in thinking may be relevant to “scientific” hypothesis generation.

The impact of stereoscopic imagery and motion on anatomical structure recognition and visual attention performance

Gross anatomy is located in a three‐dimensional space. Visualizing aspects of structures in gross anatomy education should aim to provide information that best resembles their original spatial proportions. Stereoscopic three‐dimensional imagery might offer possibilities to implement this aim, though some research has revealed potential impairments that may result from observing stereoscopic visualizations, such as discomfort. However, possible impairments of working memory such as decreased visual attention performance due to applying this technology in gross anatomy education have not yet been investigated. Similarly, in gross anatomy education the impact of stereoscopic imagery on learners’ recognition of anatomical‐spatial relationships and the impact of different presentation formats have only been investigated in a small number of studies. In this study, the performance of 171 teacher trainees working on the anatomy of hearing was examined, either with non‐stereoscopic or stereoscopic imagery. Static and dynamic picture presentations were applied. Overall, benefits for stereoscopic imagery on estimating anatomical‐spatial relations were found. The performance on a visual attention test indicates that the impact of stereoscopic visualizations on the human cognitive system varies more from person to person compared to non‐stereoscopic visualizations. In addition, combinations of temporarily moving pictures and stereoscopic imagery lead to decreased visual attention performance compared to combinations of moving pictures and non‐stereoscopic imagery.

From down house Landlord to Brazilian high school students: What has happened to evolutionary knowledge on the way?

Evolution is considered an essential topic that brings to school a broader perspective of natural phenomena and of the nature of science. Most if not all research has shown that the result of the teaching of evolutionary theories is not positive in different parts of the world. Some have attributed the poor understanding shown by students to teaching style or to students' cognitive abilities. This article reports results of interviews and tests carried out with students after they had been taught the topic of evolution. By adopting a sociocultural perspective, before terming students' views “misconceptions,” attention was given to several different ways Charles Darwin's theories have been re-interpreted by well-known scholars and offered to the public. I have analyzed the approaches taken by Emanuel Radl (1873-1942), John C. Greene, Robert Maxwell Young, and Ernst Mayr to assess the diverse ways Darwinism has been conceived. Attention was also given to the presentation of this controversial knowledge to the public in two major popular books written by respected scientists, Huxley and Kettlewell's Darwin and His World (1975) and Richard Dawkins' more recent The Blind Watchmaker (1989). These analyses revealed remarkable differences between what was written in Downe (Kent) a hundred years ago and what was heard at Sao Paulo (Brazil) nowadays. Students show very poor understanding of evolutionary theories. Their conceptions reveal evolution has been primarily related to the human species. Its meaning is understood as similar to progress, growth, multiplication, and improvement. Biological and cultural evolution are not clearly distinguished. Competition is misunderstood as pure violence, sometimes inevitable, and adaptation is considered an individual process that occurs during the organism's life span. Educational change may not depend just on teaching style and students' cognitive abilities. Modification of factual knowledge and epistemological gaps may be the result of a process of social reconceptualization of knowledge offered to students.     

The Contribution of Analogical Problem Solving and Phonemic Awareness to Children's Ability to Make Orthographic Analogies when Reading

ABSTRACT A review of current literature into children's use of orthographic analogies during reading results in an apparent contradiction: that normal readers’ ability to draw such analogies is not predicted by their prior phonological awareness (Muteret al., 1994), rather by their reading experience and proficiency (Bowey and Underwood, 1996), but that dyslexic children are less able to draw these analogies because of theirlack of phonological awareness (Hanleyet al., 1997). It is suggested that in the absence of extensive reading experience, a combination of analogous problem‐solving ability and phonological awareness may be necessary for the successful use of orthographic analogies during reading. To assess this possibility, 70 children of limited reading experience and ability were assessed on phonemic awareness, their ability to make visual analogies and use orthographic analogies when reading. Phonemic awareness was able to account for 14% of the variance in reading ability. Phonemic awareness also accounted for 40% of the variance in children's orthographic analogy scores, and the ability to make visual analogies accounted for another 5%. It was also found that the ability to make orthographic analogies does not account for variance in reading ability scores once phonemic awareness has been taken into account.     

Understandingg in terms of information processing

Psychometric g, the general factor in individual differences in all types of tests and performances involving any mental ability, has much wider importance and implications than are encompassed by the field of psychometrics. It is argued that the nature of g must be understood in terms of information processes rather than in terms of the specific knowledge and skills that are seen in the content of conventional mental tests. The wide range of individual differences in g and disparities in the distribution of g in different subpopulations have important implications for understanding some of the major problems confronting public education.     

Early adolescents' and their parents' mental imagery in relation to perceived reading competence

This cross‐sectional survey study examined the relation between mental imagery (i.e., seeing images of a story ‘in the mind's eye’) and perceived self‐competence in reading. The study was conducted with a group of seventh‐grade to ninth‐grade students in the prevocational educational track of secondary schools in the Netherlands and their parents. Results showed a moderate relation between mental imagery and self‐competence beliefs, also after controlling for the quality of students' home literacy environment. Examination of gender differences revealed that girls outperformed boys in self‐competence beliefs. Furthermore, boys perceived themselves as better readers when their parents had higher mental imagery skills. No direct relation was found between parents' and adolescents' mental imagery skills. These findings imply that parents and teachers may need to be made aware of the importance of mental imagery strategies as it may enhance the reading experiences of boys as well as girls.     

Age Differences in Imagery Abilities

Age differences were examined in 4 aspects of visual mental imagery, namely, image generation, maintenance, scanning, and rotation. The results suggested that one or more distinct processes are used to carry out each aspect of imagery, and that this is true for 5-year-olds, 8-year-olds, 14-year-olds, and adults. There was no evidence that younger children have fewer processing components, which become differentiated into more specialized subsystems over age. In addition, the results suggested that younger children are relatively poor at scanning, rotating, and generating objects in images, but are relatively good at maintaining images.
