The Relationship Between Creativity and Conformity Among Preschool Children

The current study investigated the relationship between creativity and conformity based on the work of Starkweather (1964). The subjects were 45 preschool children. Creativity was assessed using the Multidimensional Stimulus Fluency Measure (Moran, Sawyers, Fu, & Milgram, 1983), an original thinking task. Two forms of conformity were assessed: social conformity and impersonal conformity using the Starkweather Social Conformity Test and the Starkweather Form Boards Test respectively (Starkweather, 1964). Starkweather's hypothesis of a curvilinear relationship between conformity and creativity was found for the social conformity task (X² = 11.69, p < .01). The findings support the hypothesis that highly conforming and highly nonconforming children do not score as high on creativity measurements as their freedom of expression (i.e., not following a rigid pattern of conforming/nonconforming) counterparts. Chi‐square analyses revealed significantly more children in the high creativity and freedom of expression group as compared to the low creativity and conforming/nonconforming children. That is, significantly fewer children were found in the low conformity/low creativity cell and more in the low conformity/high creativity cell than were expected by chance. No differences were found for impersonal conformity, perhaps due to the insensitivity of the instrumentation to assess conformity. It is concluded that freedom of expression may be seen as an important personality trait in the identification and nurturance of creative potential and problem solving in young children.     

非母语语音短期学习的年龄效应

采用短期人工训练的范式,选取没有任何朝鲜语经验的二年级儿童、五年级儿童和大学生为被试,以一对朝鲜语语音为材料,探讨非母语语音学习的年龄效应。被试分别在学习前和每天学习后完成语音分辨测查。结果发现:(1)汉语被试辨别朝鲜语紧音/k^*/和松音/k/时存在困难;(2)在学习前,大学生的语音辨别正确率最高,五年级儿童次之,二年级儿童最低;(3)学习后,二年级儿童辨别成绩的提高量高于五年级儿童和大学生。该结果支持了学习非母语语音的年龄越小,学习效果越好、学习速度更快的假设。     

The KEY to the ROCK: Near-homophony in nonnative visual word recognition

To test the hypothesis that native language (L1) phonology can affect the lexical representations of nonnative words, a visual semantic-relatedness decision task in English was given to native speakers and nonnative speakers whose L1 was Japanese or Arabic. In the critical conditions, the word pair contained a homophone or near-homophone of a semantically associated word, where a near-homophone was defined as a phonological neighbor involving a contrast absent in the speaker’s L1 (e.g., ROCK-LOCK for native speakers of Japanese). In all participant groups, homophones elicited more false positive errors and slower processing than spelling controls. In the Japanese and Arabic groups, near-homophones also induced relatively more false positives and slower processing. The results show that, even when auditory perception is not involved, recognition of nonnative words and, by implication, their lexical representations are affected by the L1 phonology.     

Differences in brain information transmission between gifted and normal children during scientific hypothesis generation

The purpose of the present study was to investigate differences in neural information transmission between gifted and normal children involved in scientific hypothesis generation. To investigate changes in the amount of information transmission, the children’s averaged-cross mutual information (A-CMI) of EEGs was estimated during their generation of scientific hypotheses. We recorded EEG from 25 gifted and 25 age-matched normal children using 16 electrodes on each subject’s scalp. To generate hypotheses, the children were asked to observe 20 “quail eggs” that gave rise to questions. After observation, they were asked to generate a scientific hypothesis—a tentative causal explanation for the questions evoked. The results of this study revealed several distinguishing brain activities between gifted and normal children during hypothesis generation. In contrast to normal children, gifted children showed increased A-CMI values between the left temporal and central, between the left temporal and parietal, and between the left central and parietal locations while generating a hypothesis. These results suggested that gifted children more efficiently distribute the cognitive resources essential to cope with hypothesis generation.     

Context effects in the behavioral ratings of hyperactivity

It was proposed that parents of hyperactive children would observe more problems at home in some but not all home contexts. To test this hypothesis, parents of teacher-identified hyperactive and nonhyperactive children were asked to complete a context-specific behavioral rating scale (Werry, 1968). Hyperactive children were rated by their parents as changing activities, talking, interrupting, and exhibiting dependency more than nonhyperactive children. Furthermore, those differences between hyperactive and control children were observed primarily in the play and homework contexts.This research was supported by a National Institute of Mental Health Grant MH(32282).     

Socio-cognitive conflict and structure of individual and collective performances

A previous experiment (Doise, Mugny and Perret-Clermont, 1975) has shown that pairs of subjects perform better on a spatial representation task than subjects alone. As a conclusion the hypothesis was put forward that conflicts of cognitive centrations, embedded in a social situation, lead children to coordinate their centrations. The present research was planned to verify several predictions following from this general hypothesis. Results show that indeed more progress takes place when children with different cognitive strategies work together than when children with the same strategies do so, and that not only the less advanced but also the more advanced child progresses when they interact with each other.     

Identifying good opportunities to act: Implementation intentions and cue discrimination

Forming an implementation intention (‘If I encounter situation X, then I'll perform behaviour Y!’) is thought to increase the likelihood that the person will detect a good opportunity to act. Experiment 1 found support for this hypothesis in a novel context where detection of the specified cue was very difficult. Experiments 2 and 3 extended existing paradigms to test whether this improved cue detection has costs in terms of increased false positives and/or slower responses to ambiguous stimuli. This hypothesis was not supported. Forming an implementation intention led to more accurate (Experiment 2) and faster (Experiment 3) responses to the specified cue without compromising responses to non‐relevant, or ambiguous, stimuli. Overall, the findings suggest that forming an implementation intention is an effective self‐regulatory tool because the specified cues are discriminated swiftly and with precision.

Semantic and phonetic memory codes in beginning readers

In two experiments a group (N=15) of poor beginning readers and of good readers (N=15) were auditorily presented with continuous item lists. The children were asked to indicate whether each item had occurred previously in the list. In Experiment 1, using real words, later items were related either semantically or as rhymes to earlier ones. False positives to each item type were taken as indices of memory coding and showed that good readers encoded both semantic and surface aspects of items. In contrast, poor readers made a large number of meaning-based confusions (saying “old” tohouse whenhome had been presented earlier) but almost none based on rhyme (home/comb confusions). In a second experiment, with phonetically legal nonwords as items, poor readers made a significant number of phonetic false positives, although the good reader controls made more. The results are interpreted as confirming that poor readers are relatively insensitive to surface features of language but that this weakness is most marked when sound and meaning are both available as memory codes.     

Linguistic humor comprehension in children with articulation impairments

This study investigated the ability of children with articulation disorders to comprehend linguistic humor. It was hypothesized that children with articulation disorders would have more difficulty understanding humor based on phonological differences than humor based on lexical differences. A second hypothesis predicted that children with articulation disorders would have more difficulty understanding riddles in which the phoneme they misarticulated, either /s/ or /r/, was the source of ambiguity than riddles in which the source of ambiguity did not involve the phoneme they misarticulated. Results did not confirm the first hypothesis as there were no statistically significant differences between groups with regard to the children's ability to understand phonological vs lexical humor. The second hypothesis was supported. Children had significantly more difficulty understanding riddles in which the source of ambiguity related to the phoneme they misarticulated, either /s/ or /r/ than they did understanding phonological humor involving nonerror phonemes.

Waking ultradian rhythms of performance and motility in hyperkinetic and normal children

Waking ultradian rhythms in a visual performance task (detections and false positives) and in motility (global body movements and segmental limb movements during the task, and segmental limb movements during off-task periods) were examined in groups of nonmedicated hyperkinetic (HK) children (N = 11) and matched normal controls (N = 11). Testing was conducted for 5 minutes every 15 minutes (with 10-minute "rest periods") over a 6-hour period on 2 consecutive days. Increased limb movement (p less than .01) during off-task periods on both days. Increased limb movement in HK subjects during the task was marginally significant (p less than .06) on one day. False positives and global body movements failed to differentiate the groups. With regard to ultradian rhythmicity, some subjects in both groups showed evident ultradian peaks, which were present across a wide range of frequencies in one or more variables. There were no significant differences in the incidence of the period of evident ultradian peaks between the two groups.     

Discriminatory peer aggression among children as a function of minority status and group proportion in school context

This study investigates discriminatory peer aggression among primary school aged children as a function of minority status (based on nationality, ethnicity, religion) of the target and the relative proportions of minority and majority children in the school. Participants were 925 8‐ to 12‐year‐olds attending schools in Britain. Children of minority status were no more likely than children of majority background to experience peer aggression in general. However, minority children were more likely to experience being the victims of discriminatory aggression. Two contrasting predictions were tested: that discriminatory aggression would be more likely when the minority group was relatively small in number or, alternatively, that as the proportions of children of minority backgrounds increased across schools, discriminatory aggression would be greater. The latter hypothesis was supported. Findings also revealed that in schools with a lower minority presence, discriminatory aggression experienced by majority children was significantly lower than that reported by minority children. When the school minority rate exceeded 81%, discriminatory aggression was more commonly experienced among majority children than among minority children.

Graphomotor skills in children with developmental coordination disorder (DCD): Handwriting and learning a new letter

The aim of the present study was to analyze handwriting difficulties in children with developmental coordination disorder (DCD) and investigate the hypothesis that a deficit in procedural learning could help to explain them. The experimental set-up was designed to compare the performances of children with DCD with those of a non-DCD group on tasks that rely on motor learning in different ways, namely handwriting and learning a new letter. Ten children with DCD and 10 non-DCD children, aged 8–10 years, were asked to perform handwriting tasks (letter/word/sentence; normal/fast), and a learning task (new letter) on a graphic tablet. The BHK concise assessment scale for children’s handwriting was used to evaluate their handwriting quality. Results showed that both the handwriting and learning tasks differentiated between the groups. Furthermore, when speed or length constraints were added, handwriting was more impaired in children with DCD than in non-DCD children. Greater intra-individual variability was observed in the group of children with DCD, arguing in favor of a deficit in motor pattern stabilization. The results of this study could support both the hypothesis of a deficit in procedural learning and the hypothesis of neuromotor noise in DCD.     

Alternative-based thresholding with application to presurgical fMRI

Functional magnetic reasonance imaging (fMRI) plays an important role in pre-surgical planning for patients with resectable brain lesions such as tumors. With appropriately designed tasks, the results of fMRI studies can guide resection, thereby preserving vital brain tissue. The mass univariate approach to fMRI data analysis consists of performing a statistical test in each voxel, which is used to classify voxels as either active or inactive—that is, related, or not, to the task of interest. In cognitive neuroscience, the focus is on controlling the rate of false positives while accounting for the severe multiple testing problem of searching the brain for activations. However, stringent control of false positives is accompanied by a risk of false negatives, which can be detrimental, particularly in clinical settings where false negatives may lead to surgical resection of vital brain tissue. Consequently, for clinical applications, we argue for a testing procedure with a stronger focus on preventing false negatives. We present a thresholding procedure that incorporates information on false positives and false negatives. We combine two measures of significance for each voxel: a classical p-value, which reflects evidence against the null hypothesis of no activation, and an alternative p-value, which reflects evidence against activation of a prespecified size. This results in a layered statistical map for the brain. One layer marks voxels exhibiting strong evidence against the traditional null hypothesis, while a second layer marks voxels where activation cannot be confidently excluded. The third layer marks voxels where the presence of activation can be rejected.     

Birth order of past presidents and Schlesinger's history cycles: support for Stewart's leadership theory

Stewart's hypothesis (1992) that adults who were only-children and first-born children are most suited to lead communities in more turbulent times while adults who were later-born children are most suited to lead in more tranquil times was tested by relating the male birth order of elected presidents to Schlesinger's 1986 public purpose and private interest periods. Consistent with Stewart's hypothesis, candidates who were only-children and first-born children tended to win during public purpose phases, which are characterized by the turbulence of greater political commitment, idealism, and broad social change.     

Asymmetries Between Positives and Negatives

How people react to negatives (what they dislike) is not always symmetric to how they react to positives (what they like). We propose a theoretical framework that links three potentially general types of positive–negative asymmetries: asymmetry in prediction errors (people err more when predicting others' attitudes about positives than about negatives), asymmetry in consensus (people agree more among themselves about negatives than about positives), and asymmetry in base rates (there are more negatives than positives). Our theory further explores a moderator for these asymmetries – importance of the stimulus to the self: greater importance engenders greater positive–negative asymmetries. We provide empirical evidence for our theory and discuss the boundaries and implications of our propositions and findings.     

Gravity does rule for falling events

Hood (1995) reported a vertical invisible displacement task where the goal was to find a ball that was dropped down one of three chimneys connected to three hiding boxes below by opaque tubes. Preschool children exhibited perseverative search at the box directly below the chimney where the ball was dropped even though the tubes were always visible and the children were given numerous trials and feedback. This behavior was interpreted as a naive theory of gravity. The current study set out to test the naive gravity theory hypothesis by reversing the motion of the event on a television. On half of the trials the object appeared to fall up the tube into one of the boxes which were now on the top of the apparatus. There were significantly more errors for ‘down’ trials as compared to ‘up’ trials which supports the hypothesis that children are biased to infer that falling objects travel in a straight line whereas anti-gravity events do not conform to this naive theory.     

Sex Role and Attitudinal Correlates of Desired Family Size

A survey conducted in 1971 with college students as respondents tested the hypothesis that persons approving of a relatively equivalent pattern of sex roles desire to have smaller families than do persons approving of less equivalent sex roles. Though the hypothesis was confirmed for the number of children that Ss desired to procreate, approval of sex role equivalence appeared to be only one component of a more general pattern in which Ss who desired to procreate fewer children were nontraditional in their attitudes. Thus, to the extent that Ss approved of equivalent sex roles, favored Women's Liberation, opposed conservatism, favored liberalism, and considered themselves nonreligious, they tended to have smaller family size goals for biological parenthood. However, the role and attitudinal predictors related less strongly to the total number of children desired (i.e., the sum total of the number of children desired as a biological parent plus the number of adoptions desired).     

Fine motor deficiencies in children with developmental coordination disorder and learning disabilities: an underlying open-loop control deficit

Thirty-two children with Developmental Coordination Disorder (DCD) and learning disabilities (LD) and their age-matched controls attending normal primary schools were investigated using kinematic movement analysis of fine-motor performance. Three hypotheses about the nature of the motor deficits observed in children with LD were tested: general slowness hypothesis, limited information capacity hypothesis, and the motor control mode hypothesis. Measures of drawing movements were analyzed under different task conditions using a Fitts' paradigm. In a reciprocal aiming task, the children drew straight-line segments between two targets 2.5 cm apart. Three Target Sizes were used (0.22, 0.44, and 0.88 cm). Children used an electronic pen that left no trace on the writing tablet. To manipulate the degree of open-loop movement control, the aiming task was performed under two different control regimes: discrete aiming and cyclic aiming. The kinematic analysis of the writing movements of the 32 children with DCD/LD that took part in the experimental study confirmed that besides learning disabilities they have a motor learning problem as well. Overall, the two groups did not differ in response time, nor did they respond differently according to Fitts' Law. Both groups displayed a conventional trade-off between Target Size and average Movement Time. However, while movement errors for children with DCD/LD were minimal on the discrete task, they made significantly more errors on the cyclic task. This, together with faster endpoint velocities, suggests a reduced ability to use a control strategy that emphasizes the terminal control of accuracy. Taken together, the results suggest that children with DCD/LD rely more on feedback during movement execution and have difficulty switching to a feedforward or open-loop strategy.     

Social interaction and cognitive growth: An examination through the role‐taking skills of deaf and hearing children

Recent research using theory‐of‐mind tasks has rekindled interest in the possibility that social interaction makes a significant contribution to cognitive development. It is proposed here that this contribution may be most pronounced with phenomena that, like belief or affective states, are internal and abstract. A more modest contribution is envisaged with phenomena that are overt and perceptible. The proposal is explored via comparison of deaf and hearing children's ability to engage in affective and perceptual role‐taking, since the aspects of social interaction that have been implicated in cognitive development are known to be problematic for deaf children. Therefore, the proposal of more marked consequences for internal and abstract phenomena leads to the hypothesis that deaf children should lag behind hearing children on affective role‐taking, while showing little or no difference on perceptual role‐taking. The hypothesis was tested in two studies, one involving 10 deaf children and 10 hearing children aged 6.94– 8.93 years and the other involving 25 deaf children and 20 hearing children aged 5.08– 11.58 years. In both studies, affective role‐taking was examined using a task developed from Chandler (1973), while perceptual role‐taking was examined via an extension of Hughes and Donaldson's (1979) hiding task. The results provide consistent support for the hypothesis, and patterns of correlation between age, affective performance and perceptual performance give clues to the relevant developmental mechanisms.
