Perspective role-taking in young children

Children between the ages of 4 and 7 years were asked to select a photograph depicting the visual perspective of a puppet which was placed at various locations around a dollhouse in a modified version of Piaget and Inhelder's three-mountain task. A shielded condition was used for half of the children. Three types of errors were examined in relation to the shield condition, age, and type of vantage point (views from the corners and from the sides). Shielding of the stimulus array reduced egocentric errors among 4-year-olds, producing a pattern of responses more typical of that observed among older children. Increasing specificity in perspective role-taking with age was indicated by changes in error patterns. Finally, the task was more difficult on trials with corner views, particularly when the child's own view included some of the cues present in the puppet's perspective.     

The development of young children's awareness of logical inconsistencies

Research by Markman (1979) suggests that children up to 12 years of age do not spontaneously detect logical inconsistencies. The present study was directed to factors which may limit children's ability to recognize their failures to understand. A task was devised which involved materials that were clearly based on children's experiences, and which involved premises and conclusions which were presented contiguously, rather than being interspersed among other sentences. Ninety-six 5-, 6-, and 7-year-old children were asked to judge the acceptability of eight three-sentence “stories” told by a puppet, and were asked to justify their responses. The stories differed in whether they were consistent or inconsistent, and in whether the principle upon which a story's consistency depended was implicitly or explicitly stated. The results showed developmental differences. By Age 7 years, most children were quite capable of evaluating sentences for their logical consistency. Five-year-olds, however, did not perform as well on the task, especially when the information upon which the logical cohesiveness of the stories rested was implicitly, rather than explicitly, stated. An examination of the justifications provided by these children revealed that they tended to question the empirical validity of individual sentences, rather than integrate the story as a whole and examine its overall logical structure.     

Aphasics' selective deficits in appreciating grammatical agreements

This study attempted to dissociate in aphasic patients different aspects of grammatical capacity. Subjects were asked to evaluate sentences containing violations of agreements between pronouns and verbs. Agreements which are considered primarily structural in nature were violated (e.g., a surface object case like “them” placed in a surface subject sentential slot) while other violated agreements seemed to involve both structural and semantic information (e.g., lack of agreement between a pronoun and a verb in terms of the number of people performing the act). These violations were couched in one of three types of sentential frames which varied in terms of syntactic complexity (e.g., active declarative vs. passive syntactic voices). The results revealed that Broca's aphasics found agreement violations difficult to detect in complex syntactic frames. They were quite successful at detecting even violations of the largely structural “case” type of agreement, however, when couched in simpler syntactic frames. Fluent aphasics encountered more difficulty detecting violations of agreements involving both semantic and structural information than agreements which were primarily structural in nature, that is, regardless of the syntactic frame. These unique performance profiles suggest that Broca's aphasics may be agrammatic only with respect to certain aspects of a sentence's structure, and that fluent aphasics may also experience some selective—but different—grammatical deficits.     

The development of metalinguistic awareness and its relation to reading achievement

The relation between certain aspects of metalinguistic ability and reading, e.g., morpho-phonological ability and reading, has been well documented in the literature. What has not been fully discussed is the relation between structural-relational (semantic-syntactic) linguistic knowledge and reading development. This study examined two types of questions about this relation: (a) which aspects of structural-relational metalinguistic awareness in what forms and during which age periods are significantly related to reading achievement? and (b) what is the relation between metalinguistic awareness in oral language processing and written language processing? Sixty-four subjects, from fourth graders to adults, participated in the study. Each subject was asked to judge and produce corrections of nongrammatical, anomalous, and ambiguous stimulus items in sentences and passages. These items were presented in both oral and written modes. Results indicated that reading achievement and age were positively related to metalinguistic ability. Subjects were better able to judge than produce correct forms. While ambiguity was the most difficult task, nongrammaticality was the most discriminating task. Good readers' performance on oral tasks equalled their performance on written tasks by adulthood.     

Creativity Through a Lens of Social Responsibility: Implicit Theories of Creativity with Korean Samples

Implicit theories of creativity have been the subject of increased research interest in recent years. These investigations are motivated by the observation that an individual's creative activities are guided by personal definitions rather than professional theories, which may be very different. Cross-cultural studies of implicit creativity theories are rare, yet they can add significantly to our knowledge of how creativity is viewed across cultures. The nature of 428 Koreans' implicit creativity theories were identified in a prestudy, and the structure of 478 Koreans' ratings of the indicated behaviors was analyzed in Experiment 1. In Experiment 2, 211 participants evaluated the creativity of 44 hypothetical profiles based on the results of the first experiment. Results provide evidence that Korean conceptions of creativity are similar to Western conceptions, although Koreans may emphasize negative behaviors and personality characteristics (e.g., deviance) to a greater degree. When asked to use their implicit theories to evaluate the creativity of hypothetical profiles, Korean adults strongly emphasized specific cognitive, personality, and motivational aspects of creativity over noncognitive aspects (e.g., perseverance, independence).     

A cross-linguistic study of the processing of causative sentences

The comprehension of sentences expressing instigative causation (e.g., The horse makes the camel run) was investigated in children between the ages of 2;0 and 4;4, speaking English, Italian, Serbo-Croatian and Turkish. Cross-linguistic differences in development reveal the roles of morphological (causative particle, case inflection) and syntactic devices (periphrasis, word order) in guiding children's processing of such constructions. It is suggested that local cues (inflectional suffixes, particles, specialized causative verb forms) contribute to the more rapid development of sentence processing strategies in Serbo-Croatian and Turkish. The word order systems of English and Italian, which require that the listener hold the entire sentence pattern in mind in order to determine underlying semantic relations, contribute to slower development on this task.     

Learning a novel grapheme: effects of positional and phonemic context on children's spelling

Two experiments explored how children who encounter a new spelling for a phoneme generalize it to novel items. Children ages 5 1/2 to 9 (N = 123) were taught a CVC (consonant-vowel-consonant) nonword containing a new vowel spelling in the middle position (e.g., /gaik/ is spelled as giik). They were then asked to spell other nonwords containing the vowel or to judge spellings that had supposedly been produced by younger children. Children were sensitive to position in the spelling production task, being more likely to use the novel grapheme when the vowel appeared in the middle of a CVC target than when it appeared in word-initial or word-final position. Children were not significantly more likely to use the novel grapheme when the target shared the vowel and final consonant (rime) of the training stimulus than when it shared the initial consonant and vowel. Implications for views of spelling development are discussed.     

Classes,collections, and distinctive features: Alternative strategies for solving inclusion problems

This study analyzed the strategies that children ages 5 through 8 years used on two modified versions of Inhelder and Piaget's (The early growth of logic in the child. New York: Norton, 1964) class inclusion task. In two experiments, children were tested on Wilkinson's (Cognitive Psychology, 1976, 8, 64–85) “percept” inclusion task in which distinctive features marked both supraordinate and subclasses. It was hypothesized that children who fail standard Piagetian inclusion tasks succeed on the “percept” task by counting and comparing mutually exclusive features rather than using features as markers for classes and subclasses. The hypothesis was supported by children's performances on “percept” tasks in which solutions based on feature counting conflicted with solutions based on consideration of class inclusion relations. In two other experiments, children answered part-whole and part-part comparison questions in which both terms were described as classes and/or subclasses, or in which one of the two terms was described as a collection (e.g., a bunch of grapes). These experiments contrasted Markman and Seibert's (Cognitive Psychology, 1976, 8, 561–577) “organization” hypothesis that the greater psychological integrity of collections facilitates reasoning on part-whole comparison problems with the hypothesis that the faciltative effect results from the “large number” connotation of collective nouns. Results on collection problems in which parts were described as collections supported the “large number” hypothesis. Results were discussed in terms of their implications for Piaget's theory.     

Who is good at this game? Linking an activity to a social category undermines children's achievement

Children's achievement-related theories have a profound impact on their academic success. Children who adopt entity theories believe that their ability to perform a task is dictated by the amount of natural talent they possess for that task--a belief that has well-documented adverse consequences for their achievement (e.g., lowered persistence, impaired performance). It is thus important to understand what leads children to adopt entity theories. In the experiments reported here, we hypothesized that the mere act of linking success at an unfamiliar, challenging activity to a social group gives rise to entity beliefs that are so powerful as to interfere with children's ability to perform the activity. Two experiments showed that, as predicted, the performance of 4- to 7-year-olds (N = 192) was impaired by exposure to information that associated success in the task at hand with membership in a certain social group (e.g., "boys are good at this game"), regardless of whether the children themselves belonged to that group.     

Understanding quantified categorical expressions

A model of categorical inference (Revlis, 1975b) claims that a conversion operation participates in the encoding of quantified, categorical expressions. As a consequence, a reasoner is said to interpret such sentences as “All A are B” in a way that permits it to also be the case that “All B are A.” The present study examines this conception of encoding using a sentence-picture verification task. In two experiments, students were asked to judge whether one of five possible Euler diagrams was true or false of a categorical expression (e.g., All A are B, No A are B, Some A are B, Some A are not B). Verification errors support a three-stage verification model whose major component is access to a “meaning stack” representing the progressive analysis of categorical relations; at the top of that stack is a converted reading of the input sentence. These findings have implications for current conceptions of categorical inference and semantic retrieval.     

Developmental inter-relationships among concrete operational tasks: An investigation of Piaget's stage concept

One hundred and one primary school children were tested on eight concrete operational tasks. Each child's performance on each task was classified as either preoperational, transitional, or fully operational. Cross-classification tables were constructed showing the joint classification of children's performance on all possible pairs of the eight tasks. Two models of intertask relations, Wohlwill's (The study of behavioral development. New York: Academic Press, 1973) divergent-decalage and reciprocal-interaction patterns, were evaluated for their fit to the cross-classification data using χ² goodness-of-fit procedures. Instances of both these patterns were identified in the data. The findings give some support to Flavell and Wohlwill's modification of Piaget's stage concept, in which individual groupings (e.g., seriation) are the structural basis of the interrelationships among concrete operational tasks. Tasks based on the same rule showed a degree of developmental interdependence (reciprocal-interaction patterns), while tasks based on different rules appeared to develop independently (divergent-decalage patterns). However, only one-half of the cross-classification tables were adequately described by either the divergent-decalage or the reciprocal-interaction patterns.     

An examination of vicarious reinforcement processes in children

The primary purpose of the present investigation was to examine vicarious reinforcement processes in children. More specifically, the effects on one child of observing another same-sex child receive direct reinforcement were explored across three different age levels. Subjects were 216 children, randomly assigned to experimental or control conditions. For the control condition, neither child in the same-sex, same-age dyad received reinforcement for performance on the experimental task. For the experimental condition, one child in each dyad received direct social reinforcement for performance, while the other child received no social reinforcement for similar performance. Although children who observed other children receive direct social reinforcement initially increased performance (as predicted by vicarious reinforcement hypotheses), their performance soon decreased and was characterized by verbal and nonverbal responses which appeared to interfere with task performance (e.g., “Hey, I can do them too”, “Look at mine”, “There's no use in trying”). It appeared as if these observing children were being punished for their performance. Such effects were more pronounced for older than younger children; however, they were observed equally in boys and girls. Results were discussed in terms of vicarious reinforcement and “implicit punishment” hypotheses. Implications for applied settings were also addressed.     

Children's strategies in producing three-dimensional relationships on a two-dimensional surface

It is a common task to give children a picture containing implicit depth cues and to require them to extract depth information from it. The cues are always selected from the adult repertoire; little is known about children's production of their own cues. In this experiment, 5- to 10-year-old children were required to draw one object behind another in a situation in which adults invariably produce the further object partially occluded by the nearer. The results were an age-related decline in the tendency to segregate the objects and an increase in the tendency to group the objects using partial occlusion, with a cross-over at 8 years. At all ages some children drew one object inside the boundary of the other. It is argued that the results are composed of two tendencies, a gradual mastery of discrete scaling phenomena (e.g., “up” on the page means “further”) within a given style, and a set of decisions to be made between incompatible styles.     

Dual-task interference as a function of cognitive processing load

Sixteen subjects from the Naval Submarine Medical Research Laboratory participated in a dual-task study designed to measure processing requirements of a choice reaction time (RT) task. Two levels of choice RT stimulus-response (S-R)compatibility were tested with each of two tracking tasks to provide different levels of dual-task loading. In one tracking task, the target's temporal-spatial pattern was fixed; in the other, the target's path was a function of the subject's performance. In the choice RT task, compatibility was treated as a between-subjects factor, while the number of alternatives (set size) within a sequence was a within-subjects variable. Choice RT results indicated that compatibility and set size interacted; the increase in response latency as a function of set size was much greater when compatibility was low. An increase in choice RT response latency occurred when the secondary tracking task was added. Within a given compatibility level, this dual-task decrement was constant for all levels of set size; however, the magnitude of the dual-task decrement varied as a function of S-R compatibility, being greater when compatibility was low than when it was high. For these data, a model like Sternberg's (1969) stages model is seen to have more explanatory value than a pooled processing capacity model (e.g., Norman and Bobrow 1975).     

The Sum and Substance of It: The Appreciation of Mass and Count Quantifiers in Parkinson′s Disease

We performed three experiments in order to determine whether patients with Parkinson′s disease (PD) have a sentence comprehension impairment. In the first experiment, we found that nondemented PD patients were impaired at matching a short sentence containing a mass or count quantifier (e.g., "Point to the jar with many") with one of four pictures. Patients erred by pointing to the incorrect mass or count type of substance, but pointed correctly to the large or small amount of a substance in the picture. In the second experiment, we asked the same PD patients to judge short sentences containing mass or count nouns modified by mass or count adjectives (e.g., *"The glass contains many milk"). PD patients were significantly impaired at detecting errors in the agreement between a noun and a quantifying adjective and errors in the appropriate use of the plural associated with a noun. A sentence completion task was performed in order to determine whether patients impaired on both sentence-picture matching and sentence judgment tasks are also compromised in their expression of quantifiers. Some patients impaired on both tasks also had difficulty expressing quantifiers, and it is these patients who may have difficulty performing grammatical computations. Other patients were selectively impaired in their sentence-picture matching or their sentence judgments, suggesting a performance deficit concerned with a particular task. We conclude that sentence comprehension impairments in PD are multifactorial in nature.     

Are bilingual children better at ignoring perceptually misleading information? A novel test

Does speaking more than one language help a child perform better on certain types of cognitive tasks? One possibility is that bilingualism confers either specific or general cognitive advantages on tasks that require selective attention to one dimension over another (e.g. Bialystok, 2001 ; Hilchey & Klein, 2011 ). Other studies have looked for such an advantage but found none (e.g. Morton & Harper, 2007 ; Paap & Greenberg, 2013 ). The present study compared monolingual and bilingual children's performance on a numerical discrimination task, which required children to ignore area and attend to number. Ninety‐two children, ages 3 to 6 years, were asked which of two arrays of dots had ‘more dots’. Half of the trials were congruent, where the numerically greater array was also larger in total area, and half were incongruent, where the numerically greater array was smaller in total area. All children performed better on congruent than on incongruent trials. Older children were more successful than younger children at ignoring area in favor of number. Bilingual children did not perform differently from monolingual children either in number discrimination itself (i.e. identifying which array had more dots) or at selectively attending to number. The present study thus finds no evidence of a bilingual advantage on this task for children of this age.     

Assessing inference production in 5 to 7-year-olds: Benefits of using a pictorial task

IntroductionThis study focuses on the methodology used to assess children's inferential skills in a narrative comprehension context with children aged between 5 to 7 years.ObjectiveThe aim of this study is to test the validity of a pictorial task based on children's literature to probe children's ability to make inferences at different times during the listening of fictional stories.MethodThe task involves selecting one of three vignettes which best illustrates what is currently happening in the story (i.e., inferential vs. literal vs. off-topic). The choices expressed here are compared to those made during a preference task performed by the same students, which consists of selecting the vignette they like the most among each series presented in the comprehension task.ResultsFirst, based on the analysis of the data collected in the comprehension task, children most often select inferential vignettes. Second, the choices expressed in the comprehension task differ from those expressed in the preference task.ConclusionThese results confirm the relevance of using children's literature associated with a pictorial task to test children's inferential skills, even with preschoolers.     

儿童心理状态推理中的观点偏差

采用知识状态推理和冲突愿望推理任务考察儿童对知识状态和愿望状态推理的偏差。被试为108名3~5岁的儿童,结果表明在知识状态推理任务中,儿童对别人知识状态的推理会受到自己知识状态的影响,表现出自我中心的特点;而在冲突愿望推理任务中,与自己喜欢的情况相比,较小年龄的儿童在自己不喜欢的条件下更容易正确推理别人的愿望,表现出不对称性。因此儿童在对心理状态进行推理时具体表现出什么样的特点具有情境依赖性     

Can one written word mean many things? Prereaders' assumptions about the stability of written words' meanings

Results of three experiments confirmed previous findings that in a moving word task, prereaders 3 to 5 years of age judge as if the meaning of a written word changes when it moves from a matching to a nonmatching toy (e.g., when the word "dog" moves from a dog to a boat). We explore under what circumstances children make such errors, we identify new conditions under which children were more likely correctly to treat written words' meanings as stable: when the word was placed alongside a nonmatching toy without having been alongside a matching toy previously, when two words were moved from a matching toy to a nonmatching toy, and when children were asked to change what the print said. Under these conditions, children more frequently assumed that physical forms had stable meanings as they do with other forms of external representation.
