Representational constraints on children's suggestibility

ABSTRACT— In a multistage experiment, twelve 4- and 9-year-old children participated in a triad rating task. Their ratings were mapped with multidimensional scaling, from which euclidean distances were computed to operationalize semantic distance between items in target pairs. These children and age-mates then participated in an experiment that employed these target pairs in a story, which was followed by a misinformation manipulation. Analyses linked individual and developmental differences in suggestibility to children's representations of the target items. Semantic proximity was a strong predictor of differences in suggestibility: The closer a suggested distractor was to the original item's representation, the greater was the distractor's suggestive influence. The triad participants' semantic proximity subsequently served as the basis for correctly predicting memory performance in the larger group. Semantic proximity enabled a priori counterintuitive predictions of reverse age-related trends to be confirmed whenever the distance between representations of items in a target pair was greater for younger than for older children.     

Spatio-temporal constraints on upright children's coordination when hitting a moving target

To determine if the spatial and/or temporal context affected the coordination patterns of children under five in upright interceptive tasks, 3-year-olds hit a ball dropped from a ramp from five heights (1.5, 2, 2.5, 3, and 3.5 m) to control drop time. We studied the initiation time of hitting a ball with a cinematic analysis of the different joint movements (foot, knee, hip, shoulder, and hand). Two patterns of joint coordination were observed according to the rolling height of the ball: a de-synchronized pattern for heights of 2 m or above where the foot was the first to move and the hand the last, and a “synchronized” pattern, for the lowest height (1.5 m) where all joints started moving at the same time due to a strong temporal pressure. These two coordination patterns highlight a functional adaptation of body joints according to the spatio-temporal constraints among children from the age of three.     

Being a therapist in eating disorder treatment trials: constraints and creativity

This paper gives a brief overview of the sequence and content of the eating disorder treatment trials at the Maudsley Hospital in London, and describes the experience of the author working as a research therapist on these trials. It considers the different ways research constraints affected the therapist, how she learnt to make creative use of what appeared to be therapeutic restrictions, and how having her clinical freedom curtailed taught her to be more flexible and showed her new ways of understanding her patients.     

The effect of self-observation on children's problem solving

The effects of self-observation on children's problem solving were investigated. Children (N = 124) aged 6-8 years attempted to solve the 3-disc Tower of Hanoi problem. After pretesting, children were grouped into those who (a) practiced solving the(c) observed problem independently, (b) received instruction on the most efficient solution, a videotape recording of their previous attempt, and (d) served as a control. Subsequently, children were immediately tested on the 3-disc problem and a more difficult 4-disc problem. They were tested again 1 week later. Performance was most improved for children inwere maintained the practice and video conditions on the 4-disc problem. Improvements over the 1-week interval. Unique characteristics of video self-observation are discussed.     

Variability, constraints, and creativity. Shedding light on Claude Monet

Recent experimental research suggests 2 things. The first is that along with learning how to do something, people also learn how variably or differently to continue doing it. The second is that high variability is maintained by constraining, precluding a currently successful, often repetitive solution to a problem. In this view, Claude Monet's habitually high level of variability in painting was acquired during his childhood and early apprenticeship and was maintained throughout his adult career by a continuous series of task constraints imposed by the artist on his own work. For Monet, variability was rewarded and rewarding.     

Evidence of a detrimental effect of extrinsic incentives on breaking a mental set

College students were either rewarded ($1.50) or not for solving a series of 10 water-jar problems. The first 9 of these were designed to establish a set for a relatively complicated, three-jar solution (B ? A ? 2C). The 10th problem was a set breaker which required that subjects discover a simple (A-C) solution. The mental activities needed to produce a solution to the two types of problems (Problems 1 to 9 and Problem 10) were, therefore, different and one interest was in seeing whether reward would be detrimental for performance on both types of problems. It was not. Poorer reward group performance was obtained only on Problem 10. This result was not due to between-group differences in mathematical ability, and explanations in terms of differences in time taken to check answers or concern over quality of performance were considered and discounted. Measures of intrinsic interest (subject evaluations of the task and a measure of willingness to volunteer for future research) failed to support the belief that interest differences account for performance differences.     

The effect of perceived locomotor constraints on distance estimation

Two experiments were conducted to examine the ways in which the visual estimation of distance to a target is affected by constraints perceived to be placed on the subsequent locomotion to the target without vision. We hypothesized that an appraisal of impending effort would play a role in ascertaining the distance to be walked. In Experiment 1, the amount of resistance to walking was variable and unpredictable. One group of subjects performed against relatively low resistance, whereas another group performed against substantially greater resistance. In the low-resistance condition, no significant differences in CE, VE, time to target, or number of steps to target were found between any of the eight combinations of predictable or unpredictable resistances during walking. In the high-resistance condition, however, significant differences were found for CE and number of strides to target when resistance varied unpredictably during walking. Experiment 2 was similar in design but required subjects to walk with combinations of normal or short steps after they had viewed the target knowing only the gait type that would be used to begin locomotion. No differences in CE, VE, or time to target were found between four different combinations of gait type and predictability, under subjectively controlled conditions. When the step constraints were externally imposed, however, differences were found for CE. None of the results from either experiment, in which the number of strides needed to reach the target or the predictability of gait did not change from normal, supported the hypothesis that motor output requirements are necessary in forming a mental representation of the target position that can be used to walk to the target with eyes closed. Whichever locomotor technique was used to walk the estimated distance in these cases, the representation was able to be used independently. When walking mechanics were altered by externally imposed constraints, however, the success at reaching the estimated target position was reduced. These latter results are consistent with those obtained using up, down, and level walking and support the premise that mental representations used in blind walking are linked to the locomotor mechanics afforded by environmental conditions.     

Evidence of perspective-taking constraints in children's on-line reference resolution

Young children's communication has often been characterized as egocentric. Some researchers claim that the processing of language involves an initial stage that relies on egocentric heuristics, even in adults. Such an account, combined with general developmental difficulties with late-stage processes, could provide an explanation for much of children's egocentric communication. However, the experimental data reported in this article do not support such an account: In an elicited-production task, 5- to 6-year-old children were found to be sensitive to their partner's perspective. Moreover, in an on-line comprehension task, they showed sensitivity to common-ground information from the initial stages of language processing. We propose that mutual knowledge is not distinct from other knowledge relevant for language processing, and exerts early effects on processing in proportion to its salience and reliability.     

Setting limits on children's behavior: The differential effects of controlling vs. informational styles on intrinsic motivation and creativity

The imposition of external constraints on an activity has frequently been shown to undermine intrinsic motivation. Given that limits must often be set upon peoples' activities, especially in parenting and education, the present study addressed the question of whether limits can be set without undermining intrinsic motivation for the activity being limited. Using cognitive evaluation theory, contrasting limit setting styles of either a controlling or informational nature, or no limits, were placed upon forty-four first- and second-grade children engaged in a painting activity. The intrinsic motivation, enjoyment, creativity, and quality of artistic production were expected to be decreased by controlling limits relative to informational and no-limits, which were not expected to differ from each other. The results provided substantial support for these predictions, suggesting that limits can be set without undermining intrinsic motivation if they are informational in nature. Support was also found for the consensual assessment of creativity method recently developed by Amabile (1982a). Results of the study are discussed along with the general relation between creativity and intrinsic motivation.     

The level-style of creativity distinction: comments on a recent comparison of two measures of creativity style

A recent article published in this journal made a contribution to our understanding of the relationships between two measures of creativity style. The authors interpreted their results and made a few statements that made a subtle, yet substantial link between the styles measured by the assessments and creative abilities. The purpose of this commentary is to point out a more general concern relating to keeping these constructs distinct and then using clear measures to help increase our understanding and appreciation of diverse styles of creativity and how they contribute to improving creative abilities. Even those researchers who attempt to clarify the differences can slip into using language that conflates style with level.     

The effect of gaze on gaze direction while looking at art

In highly controlled cuing experiments, conspecific gaze direction has powerful effects on an observer’s attention. We explored the generality of this effect by using paintings in which the gaze direction of a key character had been carefully manipulated. Our observers looked at these paintings in one of three instructional states (neutral, social, or spatial) while we monitored their eye movements. Overt orienting was much less influenced by the critical gaze direction than what the cuing literature might suggest: An analysis of the direction of saccades following the first fixation of the critical gaze showed that observers were weakly biased to orient in the direction of the gaze. Over longer periods of viewing, however, this effect disappeared for all but the social condition. This restriction of gaze as an attentional cue to a social context is consistent with the idea that the evolution of gaze direction detection is rooted in social communication.

The effect of affective characterizations on the size of children's drawings

Previous research has yielded conflicting findings about the existence and the direction of the size changes which occur in children's drawings when they are asked to draw topics which have been given an affective characterization. The present study was designed to investigate whether children scale up the size of drawings of topics which have been given a positive characterization, and scale down the size of drawings of topics which have been given a negative characterization. The participants were 258 children aged between 4 and 11 years who completed three drawings of either a man, a dog or a tree. Each child drew a baseline drawing of a neutrally characterized figure, and two further drawings of a positively and a negatively characterized version of the same figure. It was found that the children drew the positively characterized topics larger than the neutrally characterized topics, and reduced the size of the negatively characterized topics relative to the baseline drawings. These patterns occurred at all ages and with all three drawing topics. Two possible explanations of the findings are discussed: the operation of an appetitive‐defensive mechanism in children, and the acquisition of pictorial conventions.     

The impact of eye movements on a verbal creativity task

Bilateral eye movements (EMs) have been shown to induce cognitive enhancements for episodic memory, attention, and divergent thinking. Increased interhemispheric interaction has been suggested as a possible mechanism behind the EM effect, but other theories, including an increase in attentional control following EMs have also been proposed. The present research explored whether the bilateral EM effect could be extended to a creativity task that draws heavily on convergent thinking. Participants were randomly assigned to one of four EM conditions (bilateral, centre control, right-centre, or left-centre) and were presented with compound remote associate problems. After 7 s, participants were asked to make a solution/non-solution judgement to a target word presented in the left or right visual field. Bilateral and right-centre EM conditions exhibited enhanced performance on the task, with the bilateral condition demonstrating the best performance for solution targets and the right-centre condition presenting the best performance for non-solution targets. The implications of these findings are discussed in light of the neural components of creativity and theories surrounding the effects of EMs on cognition.     

The effect of pictorial detail and elaboration on children's retention.

In a visual memory task, two degrees of stimulus detail were compared to test Reese's hypothesis that stimulus detail would facilitate retention of paired associates for young children. Stimuli were presented in an elaborated or nonelaborated fashion so that the effect of detail on retention of both types of materials could be investigated. Four and 5 year-old children were included to assess a reported developmental trend that elaboration facilitates retention for older children but fails to do so for younger children. Both age groups performed equally well, and detail had no effect. Elaboration aided retention significantly. A second study, in which difficulty of the task was increased, yielded equivalent results. The constraints on performance by recall and recognition tasks were discussed.     

The effect of transgressor's and victim's sex on children's punish-help judgments

The present investigation, expanding upon a study by Miller and McCann, sought to determine whether children's reactions to the perpetrators and victims of antisocial behavior are influenced by the sex of the individuals involved. Third- and fifth-grade children were asked their opinions of a series of stories in which one child (boy or girl) was described as having intentionally harmed another child (boy or girl). The results indicate that the relative importance that children attribute to punishing transgressors and helping victims is mediated by the sex composition of the transgressor-victim dyad.     

Temporal constraints on the McGurk effect

Three experiments are reported on the influence of different timing relations on the McGurk effect. In the first experiment, it is shown that strict temporal synchrony between auditory and visual speech stimuli is not required for the McGurk effect. Subjects were strongly influenced by the visual stimuli when the auditory stimuli lagged the visual stimuli by as much as 180 msec. In addition, a stronger McGurk effect was found when the visual and auditory vowels matched. In the second experiment, we paired auditory and visual speech stimuli produced under different speaking conditions (fast, normal, clear). The results showed that the manipulations in both the visual and auditory speaking conditions independently influenced perception. In addition, there was a small but reliable tendency for the better matched stimuli to elicit more McGurk responses than unmatched conditions. In the third experiment, we combined auditory and visual stimuli produced under different speaking conditions (fast, clear) and delayed the acoustics with respect to the visual stimuli. The subjects showed the same pattern of results as in the second experiment. Finally, the delay did not cause different patterns of results for the different audiovisual speaking style combinations. The results suggest that perceivers may be sensitive to the concordance of the time-varying aspects of speech but they do not require temporal coincidence of that information.     

The roots of creativity

The various factors which seem to be important in the creative child with extraordinary potential include: A good biologic endowment, often with high intelligence and a correlation between special sensory sensitivities and other physical requirements to implement the special interest. There is also sometimes the capacity to utilize or else compensate for deficit. The fostering of interests by a parent or interested adult. Specific kinds of ongoing encouragement. Sometimes there is self-selection of interest by the child. The child must feel valued and loved. The family background and relationship of parents centers on the child. The time, place, and institutions foster the development of interest and value of the work and the child's belief in its value. The child is allowed freedom of development, without undue inhibition or restriction. Creative people have shown uneven development--the child is not "age-specific" generally. Gifted children have been observed to tolerate isolation and even loneliness well--these are often necessary conditions for developing skills. For some creative people, early object losses seem to be frequent. The creative child is curious and a keen observer. The creative child has an uncanny ability to make connections--to perceive similarities in the apparently dissimilar. The creative child is not hampered by conventional thought. The creative child has a capacity for love and devotion--or at least a positive orientation; a spiritness or passion; and a spirituality or unworldliness. It has been said that the poetic truths in a work of art are only half understood by its creator. Generally conveyed subliminally, these truths are revealed in different ways to different audiences at different times. Such is the view of William Livingstone (1987), and considering the childhood antecedents of creative work helps to understand why this is so.

Learning in context: linguistic and attentional constraints on children's color term learning

Three experiments investigated whether linguistic and/or attentional constraints might account for preschoolers' difficulties when learning color terms. Task structure and demands were equated across experiments, and both speed and degree of learning were compared. In Experiment 1, 3-year-olds who were matched on vocabulary score were taught new secondary color terms by corrective, semantic, or referential linguistic contrast. Corrective contrast produced more rapid and more extensive learning than did either semantic or referential contrast, supporting the hypothesis that targeted linguistic feedback facilitates learning. Experiment 2 replicated and extended the first experiment with Italian children and found cross-cultural differences in the amount learned about colors named differently in the two languages. In Experiment 3, some of the children were introduced to the new terms within a context of enhanced perceptual salience. These children learned as fast and performed as accurately as those given corrective linguistic feedback in Experiment 1.
