Development of knowledge about the appearance-reality distinction

7 studies of the acquisition of knowledge about the appearance-reality distinction suggest the following course of development. Many 3-year-olds seem to possess little or no understanding of the distinction. They fail the simplest Appearance-Reality (AR) tasks and are unresponsive to efforts to teach them the distinction. Skill in solving simple AR tasks is highly correlated with skill in solving simple perceptual Perspective-taking (PT) tasks; this suggests the hypothesis that the ability to represent the selfsame stimulus in two different, seemingly incompatible ways may underlie both skills. Children of 6-7 years have acquired both skills but nevertheless find it very difficult to reflect on and talk about such appearance-reality concepts as "looks like," "really and truly," and "looks different from the way it really and truly is." In contrast, children of 11-12 years, and to an even greater degree college students, possess a substantial body of rich, readily accessible, and explicit knowledge in this area.     

Junin Quechua Children's Understanding of Mind

2 tasks that examine the child's understanding of false belief, representational change, and the appearance-reality distinction were conducted among 34 4- to 8-year-old Junin Quechua children in Peru. A majority of children demonstrated an understanding of the appearance-reality distinction, though there was a clear improvement with age. Both younger and older children, however, performed poorly on questions that tested their understanding of representational change and false belief. These results raise questions as to whether or not thinking about thought and its relation to action develops in a similar manner in all cultures. If the Junin Quechua children's understanding of the appearance-reality distinction is grounded in the same representational ability that is necessary to understand one's own and another's misrepresentation of reality, then we must look for other factors that prevent them from performing correctly on tasks that test their understanding of false belief and representational change.     

Children's understanding of the distinction between real and apparent emotion

2 experiments examined children's understanding of the distinction between real and apparent emotion. In Experiment 1, 6- and 10-year-old children listened to stories in which it would be appropriate for the story protagonist to feel either a positive or negative emotion but to hide that emotion. Subjects were asked to say both how the protagonist would look and how the protagonist would really feel, and to justify their claims. The results indicated that 6- and 10-year-olds alike could distinguish quite accurately between real and apparent emotion, although 10-year-olds were somewhat better at justifying this distinction. In Experiment 2, a slightly modified procedure was used to test 4- and 6-year-olds. Again, 6-year-olds demonstrated their grasp of the difference between real and apparent emotion, and even 4-year-olds showed a limited grasp of the distinction. The findings are discussed in relation to recent research concerning children's concept of mind, their grasp of the appearance-reality distinction, their ability to produce complex, embedded justifications, and their ideas about emotion.     

Children's understanding of representational change and its relation to the understanding of false belief and the appearance-reality distinction

This research concerns the development of children's understanding of representational change and its relation to other cognitive developments. Children were shown deceptive objects, and the true nature of the objects was then revealed. Children were then asked what they thought the object was when they first saw it, testing their understanding of representational change; what another child would think the object was, testing their understanding of false belief; and what the object looked like and really was, testing their understanding of the appearance-reality distinction. Most 3-year-olds answered the representational change question incorrectly. Most 5-year-olds did not make this error. Children's performance on the representational change question was poorer than their performance on the false-belief question. There were correlations between performance on all 3 tasks. Apparently children begin to be able to consider alternative representations of the same object at about age 4.     

Children''s Understanding of the Modal Expression of Speaker Certainty and Uncertainty and Its Relation to the Development of a Representational Theory of Mind

2 experiments examined children's understanding of the expression of speaker certainty and uncertainty and its relation to their developing theory of mind. In the first experiment, 80 children between 3 and 6 years of age were presented with a task in which they had to guess the location of an object hidden in 1 of 2 boxes. As clues to location, the children were presented with contrasting pairs of statements by 2 puppets. Different trials contained all of the possible pairwise combinations of either the modal verbs must, might, and could or the modal adjuncts probably, possibly, and maybe. Results showed that while 3-year-olds did not differentiate between any of the modal contrasts presented, 4-year-olds and older children were able to find the hidden object on the basis of what they heard. Performance was best for contrasts involving a highly certain term (either must or probably) paired with a less certain term (might, could, possibly, and maybe). Experiment 2 was designed to determine whether competence with modal terms was related to competence with mental terms in the same task, and whether performance on the certainty task was related to other aspects of the child's understanding of the nature of beliefs. 26 4-year-olds were presented with the certainty task, involving both modal and mental terms, and with tasks assessing their understanding of false beliefs, representational change, and the appearance-reality distinction. Results showed that all of these tasks were intercorrelated, implying that what may develop at 4 years of age may be a general understanding of the representational nature of belief.     

Seeing and believing: children's understanding of the distinction between appearance and reality

When young children are asked questions about objects with misleading appearances, they make two kinds of errors: (1) phenomenism--they report appearance when asked to report reality; and (2) intellectual realism--they report reality when asked to report appearance. Two studies with 3-year-old children tested the hypothesis that phenomenism errors predominate when children are asked about objects' real and apparent properties, whereas intellectual realism errors predominate when children are asked about objects' real and apparent identities. The results of these studies provided some support for the property-identity hypothesis; children's appearance-reality judgments about properties tended to differ from those about identities. More phenomenism errors were elicited when the stimuli were described to the children in terms of their properties than when the very same stimulus objects were described in terms of their identities. Identity tasks were not found to elicit predominantly intellectual realism errors, although the data showed trends in this direction. The implications of these results for theories about young children's tendency to accept things in terms of their perceptual characteristics were briefly discussed.     

More than relations between self,others and nature: outdoor education and aesthetic experience

Self, others and nature (environment) have been suggested over numerous decades and in various places as a way of understanding experience in outdoor education. These three elements and the relations between them appear to cover it all. But is this really the final word on understanding experience? In this paper I explore two emphases within experience expressed by Peirce that offer differing ways of understanding experience: in one emphasis self, others and nature are submerged and not discerned; in the other they appear as the three familiar and related elements. The first emphasis is phenomenological and focused on a simple whole; the other is pragmatic and concerned with a total whole (elements in a totality). The key distinction here is that between something simple (one-fold) and something total (manifold). For Heidegger the difference between these is the ontological difference, where the two differing emphases are be-ing (verb) and beings (noun); or, expressed in another way, phenomenological thinking and calculative thinking. For Dewey these two emphases are revealed as aesthetic and reflective experience, both connected via inquiry. Awareness of this difference and connection suggests that issues involving self, others and nature as elements emerge from and return to the aesthetic ways of being (or occupations) that we build through our programme design and conduct. Relations between self, others and nature are submerged within these ways of being, highlighting how our programme design and conduct does not merely concern activities (including reflective activities), but involves building ways of being.     

Executive processes in appearance-reality tasks: the role of inhibition of attention and symbolic representation

Two studies addressed the role of representation ability and control of attention on solutions to an appearance-reality task based on two types of objects, real and representational. In Study 1, 67 preschool children (3-, 4-, and 5-year-olds) solved appearance-reality problems and executive processing tasks. There was an interaction between object type (real vs. representational) and question type (appearance vs. reality) on problem difficulty. In addition, representational ability predicted performance on appearance questions and inhibitory control predicted performance on reality questions. In Study 2, 95 children (4- and 5-year-olds) who were monolingual or bilingual solved similar problems. On appearance questions, groups performed equivalently but on reality questions, bilinguals performed better (once language proficiency had been controlled). The difference is attributed to the advanced inhibitory control that comes with bilingualism.     

Young Children''s Understanding of the Role That Sensory Experiences Play in Knowledge Acquisition

3 studies investigated whether young children understand that the acquisition of certain types of knowledge depends on the modality of the sensory experience involved. 3-, 4-, and 5-year-old children were exposed to pairs of objects that either looked the same but felt different, or that felt the same but looked different. In Study 1, 36 children were asked to state, when one of these objects was hidden inside a toy tunnel, whether they would need to see the object or feel it in order to determine its identity. In Study 2, 48 children were asked to state which of 2 puppets knew that an object hidden inside a tunnel possessed a given visual or tactile property, when one puppet was looking at the object and the other was feeling it. In Study 3, 72 children were asked, in a scenario similar to Study 2, to state for each puppet whether he could tell, just by looking or by feeling, that the hidden object possessed a certain visual or tactile property. Children were also asked what was the best way to find out whether a given object possessed a certain visual or tactile property. Results of all 3 studies suggest that an appreciation of the different types of knowledge our senses can provide (i.e., modality-specific knowledge) develops between the ages of 3 and 5. The results are discussed in relation to young children's developing understanding of the role that informational access plays in knowledge acquisition.     

Theory of mind and relational complexity

Cognitive complexity and control theory and relational complexity theory attribute developmental changes in theory of mind (TOM) to complexity. In 3 studies, 3-, 4-, and 5-year-olds performed TOM tasks (false belief, appearance-reality), less complex connections (Level 1 perspective-taking) tasks, and transformations tasks (understanding the effects of location changes and colored filters) with content similar to TOM. There were also predictor tasks at binary-relational and ternary-relational complexity levels, with different content. Consistent with complexity theories: (a) connections and transformations were easier and mastered earlier than TOM; (b) predictor tasks accounted for more than 80% of age-related variance in TOM; and (c) ternary-relational items accounted for TOM variance, before and after controlling for age and binary-relational items. Prediction did not require hierarchically structured predictor tasks.

The Internalization of Jewish Values by Children Attending Orthodox Jewish Schools,and its Relationship to Autonomy-Supportive Parenting and Adjustment

The present study examined the way in which children attending Orthodox Jewish schools internalize the value of both their Jewish studies and secular studies, as well as the value of Jewish cultural practices. A distinction was made between identified internalization, where children perceive Jewish studies and Jewish culture to be an important part of their sense of self, and introjected internalization, where children participate in Jewish studies and Jewish culture because they feel like they “ought to” or because of external pressures. Primary identified reasons for their Jewish studies and Jewish cultural practices were significantly associated with positive self and teacher ratings of adjustment; internalization of secular studies was unrelated to adjustment. The study also found that parental support of autonomy, which involves allowing children some latitude in making decisions for themselves regarding religious issues, was associated with greater identification. Together, these results highlight the importance of autonomy-supportive parenting in promoting identification of adolescents' Jewish identity.

Learning radiological appearances of diseases: Does comparison help?

Comparison learning is a promising approach for learning complex real-life visual tasks. When medical students study radiological appearances of diseases, comparison of images showing diseases with images showing no abnormalities could help them learn to discriminate relevant, disease-related information. Medical students studied 12 diseases on chest x-ray images. They were randomly assigned to a group (n = 31) that compared radiographs of diseases with normal images and a group (n = 30) that only studied radiographs of diseases. On a visual diagnosis test, students who compared with normal images during study were better able to diagnose focal diseases (i.e., lesions at one location) than students who could not compare, but for the diagnosis of diffuse diseases (i.e., involving both lungs) there was no significant difference between groups. Results show that comparison with normal images made it easier to discriminate relevant information for focal diseases.     

Visualizing Without Vision at the Microscale: Students With Visual Impairments Explore Cells With Touch

Science instruction is typically highly dependent on visual representations of scientific concepts that are communicated through textbooks, teacher presentations, and computer-based multimedia materials. Little is known about how students with visual impairments access and interpret these types of visually-dependent instructional materials. This study explored the efficacy of new haptic (simulated tactile feedback and kinesthetics) instructional technology for teaching cell morphology and function to middle and high school students with visual impairments. The study examined students’ prior experiences learning about the cell and cell functions in classroom instruction, as well as how haptic feedback technology impacted students’ awareness of the 3-D nature of an animal cell, the morphology and function of cell organelles, and students’ interest in the haptic technology as an instructional tool. Twenty-one students with visual impairment participated in the study. Students explored a tactile model of the cell with a haptic point probe that allowed them to feel the cell and its organelles. Results showed that students made significant gains in their ability to identify cell organelles and found the technology to be highly interesting as an instructional tool. The need for additional adaptive technology for students with visual impairments is discussed.This material is based upon work supported by the National Science Foundation under Grant Numbers 0354578 and 0411656     

How Does It Look? Level 2 Perspective‐Taking at 36 Months of Age

Previous research has found that children engage in Level 2 visual perspective-taking, that is, the understanding that others may see things in a different way, between 4 and 5 years of age (e.g., J. H. Flavell, B. A. Everett, K. Croft, & E. R. Flavell, 1981). This ability was reexamined in 36-month-olds using color filters. In Experiment 1 (N = 24), children had to recognize how an object looked to an adult when she saw it through a color filter. In Experiment 2 (N = 24), a novel production test was applied. Results of both studies show that 36-month-olds know how an object looks to another person. The discussion focuses on the psychological requirements of visual perspective-taking and its relation to other "theory of mind" abilities, such as the distinction between appearance and reality and understanding false belief.     

Effects of tactile training on visual speechreading: performance changes related to individual differences in cognitive skills

We report on a follow-up study of the R?nnberg, Andersson, Lyxell, & Spens (1998) speech tracking training study. The purpose was to examine, initially and after training, the effects of different tactile aids on tasks of visual speechreading. We also examined cognitive prerequisites for initial baseline speechreading and posttraining speechreading performance. Compared with speechreading alone, tactile aids impaired sentence-based speechreading at first, although performance improved with training. No effects of vibrotactile aids or training were obtained for visual word-decoding. Initial baseline speechreading performance and posttraining performance correlated with cognitive skills, but the size of the correlations changed. The size of the correlations also varied with the different tactually mediated speechreading conditions.     

The Developing Bodily Self: How Posture Constrains Body Representation in Childhood

Adults’ body representation is constrained by multisensory information and knowledge of the body such as its possible postures. This study (N = 180) tested for similar constraints in children. Using the rubber hand illusion with adults and 6- to 7-year olds, we measured proprioceptive drift (an index of hand localization) and ratings of felt hand ownership. The fake hand was either congruent or incongruent with the participant’s own. Across ages, congruency of posture and visual–tactile congruency yielded greater drift toward the fake hand. Ownership ratings were higher with congruent visual–tactile information, but unaffected by posture. Posture constrains body representation similarly in children and adults, suggesting that children have sensitive, robust mechanisms for maintaining a sense of bodily self.
