The Development of Verb Concepts: Children''s Use of Verbs to Label Familiar and Novel Events 总被引：1，自引：0，他引：1
Douglas A. Behrend 《Child development》1990,61(3):681-696
The importance of actions, results, and instruments in verb concepts was examined in four studies. Study 1 investigated how children label familiar events for which instrument, action, and result verbs were appropriate labels. In Study 2, subjects were taught novel verbs and were asked to use these verbs to label events in which the instrument, action, or result had been changed. Study 1 showed that 3-year-olds used action verbs more frequently than older children and adults, and that they preferred to use an action verb over a result verb when both verbs were appropriate labels. Instrument verbs were used most frequently as first responses to the events, and were most frequently used by older children and adults. In Study 2, subjects were least likely to use the novel verbs to label events in which the result had changed. This effect increased with age. Action changes had a moderate effect for all age groups, while instrument changes had the weakest effect. Studies 3 and 4 ruled out stimulus salience and a familiar word strategy as interpretations of these findings. The studies are discussed in terms of current theory and research on conceptual development, word-learning strategies, and the semantic organization of nouns and verbs. 相似文献

The effect of personal relevance was examined as a motivational alternative to capacity-based explanations of young children's failure to describe others in terms of psychological characteristics. In Study 1, children at 2 age levels (5-6 and 9-10 years) were asked to describe actors exhibiting different behaviors and to select partners for different games. As predicted, children who expected to interact with the actors were much more likely to describe them in psychological terms. Older children selected partners based on instrumental goals, maximizing their own outcomes, whereas younger children selected partners based on liking. The findings were replicated in Study 2, and expecting interaction was also found to affect behavior (toy allocation). The results suggest that the verbal inferencing skills of young children have been underestimated in the past, and that younger children may be more oriented than older children toward affective relative to instrumental goals in anticipating interaction with a peer. 相似文献

Fledgling Theories of Mind: Deception as a Marker of Three-Year-Olds' Understanding of False Belief 总被引：3，自引：1，他引：3
3 studies involving more than 70 3- and 4-year-olds were carried out in an effort to better secure an earlier but controversial set of findings interpreted as demonstrating that children younger than 4 already have a grasp of the possibility of false belief, and consequently deserve to be credited with some authentic if fledgling theory of mind. These studies, which relied on a measure of deceptive hiding rather than more familiar "unexpected change" procedures for indexing false belief understanding, all demonstrated that even the youngest of these subjects: (a) accurately anticipated the likely impact of their deceptive strategies on both the behaviors (Study 1) and beliefs (Study 3) of their opponents, and (b) were able to selectively employ these same methods of information management as a means of helping as well as hindering the efforts of others (Study 2). 相似文献

4-5-year-old, 6-7-year-old, and 8-9-year-old children were given picture-recognition tasks in which recognition stimuli were systematically varied with respect to familiarization stimuli. Subjects were required either to verbalize or remain silent during familiarization and to identify either central figure only or whole picture recognition. Results suggested that (a) young children base recognition primarily on central figure whereas older children are more likely to utilize the entire stimulus array, and (b) younger children are more likely than older children to use spoken labels as a basis for recognition when they verbalize during familiarization. 相似文献

The ability to recall is something that most intact adults take for granted. For much of the last century, this feature of mental life was not considered to extend to very young children. There now is evidence that 1- to 2-year-olds are able to recall specific events after delays of several months. Over the short term, 1- to 2-year-olds' recall is affected by the same factors that affect older children's recall; it is not clear whether similar effects are apparent over the long term. Moreover, although age-related increases in long-term recall are assumed, there have been few empirical tests of the question. We examined recall by 14- to 32-month-olds for events experienced at 13 to 20 months. Using elicited imitation of novel multistep event sequences we examined effects of (a) delay length, (b) age at the time of experience, (c) temporal structure of events, (d) mode of experience of events, and (e) availability of verbal reminders, on long-term recall. Participants were 360 children enrolled at 13 (n = 90), 16 (n = 180), and 20 (n = 90) months. All of the 13-month-olds and half of the 16-month-olds were tested on 3-step event sequences; all of the 20-month-olds and half of the 16-month-olds were tested on 4-step event sequences. Within each age and step-length group, equal numbers of children were tested after intervals of 1, 3, 6, 9, and 12 months (n = 18 per cell). Children were tested on a variety of sequence types. For half of the events, imitation was permitted prior to the delay; for the other half, children were not permitted imitation. At delayed testing, children experienced a recall period during which they were cued by the event-related props alone, followed by a period in which recall was cued both by the event-related props and by verbal labels for the event sequences. Within step-length groups, the length of time for which older and younger children showed evidence of memory did not differ. Nevertheless, when the children were prompted by the event-related props alone, there were age-related differences in the robustness of children's memories (as indexed by higher levels of recall for older children relative to younger children). When the children were prompted by the props and by verbal labels for the event sequences, at the longer retention intervals, there were age-related differences in the robustness of children's memories and in the reliability with which recall was evidenced (as indexed by the larger numbers of older children evincing recall). Age-related effects were particularly apparent on children's ordered recall. Across the entire age range, the children were similarly affected by the variables of sequence type, opportunity for imitation, and verbal reminding. 相似文献

Essentialism is the belief that certain characteristics (of individuals or categories) may be relatively stable, unchanging, likely to be present at birth, and biologically based. The current studies examined how different essentialist beliefs interrelate. For example, does thinking that a property is innate imply that the property cannot be changed? Four studies were conducted, examining how children (N=195, grades 1-7; ages 7-13) and adults (N=187) reason about familiar and novel social characteristics. By 3rd grade (9 years), children showed some coherence of essentialist beliefs. In contrast, younger children expected less interrelatedness among dimensions than older children or adults. These findings suggest that essentialist attributions at first consist of separate strands that children eventually link together into a more coherent understanding. 相似文献

Previous research on adults' and children's memory for the time of past events has generally overlooked the fundamental distinction between knowledge of temporal distance in the past and knowledge of temporal locations. This study applied the distinction to the development of time memory. Children of 4, 6, and 8 years of age experienced 2 target events, one 7 weeks and the other 1 week before testing. They were asked to judge the relative recency of the 2 events and to localize the older event by time of day, day of the week, month, and season. Even the 4-year-olds were successful in judging the relative recency of the 2 events and localizing the older event by time of day. However, on the 3 longer time scales, only the 6- and 8-year-olds could localize the older event, reason about possible times that it could have occurred, or tell the present time. The great accuracy of the time-of-day judgments at all 3 ages is almost certainly not due to distance-type information. The results show the separate development of distance and location judgments. 相似文献

This experiment assessed the effect of the amount of physical detail in pictures on picture recognition memory for 7-year-olds, 9-year-olds, young adults, and older adults over 68. Subjects were presented simple and complex line drawings, factorially combined in a "same-different" recognition test with simple or complex forms of each. For each age group, recognition accuracy was significantly higher for pictures presented in the simple than in the complex form. This effect was due to differences between simple and complex pictures in the correct rejection rate but not the hit rate; subjects were less accurate detecting deletions from changed complex pictures than additions to changed simple pictures. The older adults were no better than chance at correctly rejecting changed complex pictures. Although increasing the presentation duration from 5 sec to 15 sec increased overall accuracy, it did not increase subjects' ability to correctly reject changed complex pictures. Results are interpreted in terms of schematic encoding and storage of pictures. Accordingly, visual information that communicates the central schema of each picture is more likely to be encoded and retained in memory than information that does not communicate this schema. 相似文献

A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a particular spatial location rather than to an object. Results show that 10-month-olds can learn new labels and do so by relying on the perceptual salience of an object instead of social cues provided by a speaker. This is in direct contrast to the way in which older children (12-, 18-, and 24-month-olds) learn and extend new object names. 相似文献

Prior research has demonstrated individual differences in children's beliefs about the stability of traits, but this focus on individuals may have masked important developmental differences. In a series of four studies, younger children (5-6 years old, Ns = 53, 32, 16, and 16, respectively) were more optimistic in their beliefs about traits than were older children (7-10 years old, Ns = 60, 32, 16, and 16, respectively) and adults (Ns = 130, 100, 48, and 48, respectively). Younger children were more likely to believe that negative traits would change in an extreme positive direction over time (Study 1) and that they could control the expression of a trait (Study 3). This was true not only for psychological traits, but also for biological traits such as missing a finger and having poor eyesight. Young children also optimistically believed that extreme positive traits would be retained over development (Study 2). Study 4 extended these findings to groups, and showed that young children believed that a majority of people can have above average future outcomes. All age groups made clear distinctions between the malleability of biological and psychological traits, believing negative biological traits to be less malleable than negative psychological traits and less subject to a person's control. Hybrid traits (such as intelligence and body weight) fell midway between these two with respect to malleability. The sources of young children's optimism and implications of this optimism for age differences in the incidence of depression are discussed. 相似文献

This study investigated the ability of children from three age groups (4, 8, and 11 years of age; N = 72) to categorize three different types of intentionally false and true statements as lies and truths, and also measured their evaluation of such statements. Results revealed that the older children were more likely to categorize false statements as lies and true statements as truths than were the 4-year-olds. All children evaluated telling lies as worse than telling truths. Antisocial lies were rated as the most serious lie type and "white lies" as the least serious. Anticipated regulatory control was more advanced for the 8- and 11-year-olds, who expected both self-approval for truth-telling and self-disapproval for lying for two of the three truth and lie types; the younger children did not anticipate greater self-approval for truth-telling and self-disapproval for lying for any of the truth and lie types. 相似文献

OBJECTIVE: It is widely presumed that when children are hit by peers or siblings, it is not as serious as similar acts between adults or older youth, which would be termed, "assaults" and "violent crimes". The goal of this study was to compare the violent peer and sibling episodes of younger children to those of older youth in terms of their seriousness and association with symptoms that might indicate traumatic effects. METHOD: The study collected reports of past year's violent victimizations and childhood symptoms in a national probability telephone sample of 2030 children and youth ages 2-17. The experiences of 10-17-year olds were obtained via self-reports and those of the 2-9-year olds from caregivers. RESULTS: The younger children's peer and sibling victimizations were not less serious than the older youth on the dimensions of injury, being hit with an object that could cause injury or being victimized on multiple occasions. Younger children and older youth also had similar trauma symptom levels associated with both peer and sibling victimization. CONCLUSION: There was no basis in this study for presuming peer and sibling victimizations to be more benign when they involve younger children. The findings provide justification for being concerned about such peer and sibling violence in schools and families and for counting such victimizations in victimization inventories and clinical assessments. 相似文献

2 studies of 8- and 11- year-old children explored factors related to willingness $$. Study I assessed baseline gender prefernces and gender-reiatd cognitive flexibility. While older children were found to have greater congnitive flexibility, and older boys had more stereotyped preferences, such questionnaire measures were not highly predictive of gender-atraditional behavior. Study 2 explored the parameters of vicarious social reinforcement in the symbolic modeling of gender-atraditional behavior. Peer reinforcers were more effective with younger children and on child-oriented tasks, whereas adult reinforcers were more effective with older children and on adult-oriented gender tasks. Both studies found that considerably more atraditional behavior was elicited with male examiners, suggesting more attention needs to be paid to this variable. Possible mechanisms underlying this effect are discussed. 相似文献

Research on memory for time has been limited by the difficulty of disentangling several of the fundamentally different processes that contribute to a chronological sense of the past. This study used a developmental approach to isolate one of these processes, impressions of distances in the past. Large samples of children between 3 and 12 years were asked to judge which was longer ago, their birthday or Christmas (and, in one study, Halloween and Thanksgiving). Even children under 6 years of age were able to discriminate the recency of their birthday and Christmas with great accuracy when the events were widely separated and one was within the past several months. The ability to discriminate recency on these scales appears to be a basic property of human memory that changes little with development. Other information about the locations of the events and their relative times of occurrence could only be interpreted correctly by children older than 9 years. 相似文献

A “digital revolution” has introduced new privacy violations concerning access to information stored on electronic devices. The present two studies assessed how U.S. children ages 5–17 and adults (N = 416; 55% female; 67% white) evaluated those accessing digital information belonging to someone else, either location data (Study 1) or digital photos (Study 2). The trustworthiness of the tracker (Studies 1 and 2) and the privacy of the information (Study 2) were manipulated. At all ages, evaluations were more negative when the tracker was less trustworthy, and when information was private. However, younger children were substantially more positive overall about digital tracking than older participants. These results, yielding primarily medium-to-large effect sizes, suggest that with age, children increasingly appreciate digital privacy considerations. 相似文献

Abstract reasoning is critical for science and mathematics, but is very difficult. In 3 studies, the hypothesis that alternatives generation required for conditional reasoning with false premises facilitates abstract reasoning is examined. Study 1 (n = 372) found that reasoning with false premises improved abstract reasoning in 12- to 15-year-olds. Study 2 (n = 366) found a positive effect of simply generating alternatives, but only in 19-year-olds. Study 3 (n = 92) found that 9- to 11-year-olds were able to respond logically with false premises, whereas no such ability was observed in 6- to 7-year-olds. Reasoning with false premises was found to improve reasoning with semiabstract premises in the older children. These results support the idea that alternatives generation with false premises facilitates abstract reasoning. 相似文献

The present study examined whether younger observers (kindergartners, second graders, and fourth graders) could extract relative weight information from collisions and also lifting events, and if they could judge whether collisions were natural (i.e., momentum conserving) or anomalous (non-momentum conserving). 20 children at each age and 20 adults viewed videotapes of 8 collisions (4 natural, 4 anomalous) and 6 sequences of lifting events. Observers also viewed sequences of static images taken from these events. Observers at all grade levels were able to reliably judge relative weight in both collisions and lifting events, and could differentiate between natural and anomalous collisions. Performance was much poorer when static sequences of the events were viewed, especially for the young children. A consistent age trend was noted across tasks: adults performed better than second and fourth graders who, in turn, performed better than kindergartners. In addition, there was evidence that younger children were differentially aided when the kinematics of the event made the kinetics more pronounced. 相似文献

Although infantile amnesia has been investigated for many years in adults, only recently has it been investigated in children. This study was a 2-year follow-up and extension of an earlier study. Children (4-13 years old) were asked initially and 2 years later for their earliest 3 memories. At follow-up, their age at the time of these memories shifted to several months later, with younger children unlikely to provide the same memories. Moreover, when given cues about memories recalled 2 years previously, many were still not recalled. In contrast, older children were more likely to recall the same memories, and cues to former memories were successful. Thus, older children were becoming consistent in terms of recalling very early memories. 相似文献

The effects of salience on 4- and 6-year-old children's ability to classify multiplicatively was investigated. A rank-ordered salience hierachy consisting of 3 dimensions was first assessed for each S. Several weeks later half the Ss of each age group were presented with a series of 9 3 times 3 matrix problems consisting of values from 2 dimensions ranked high in salience. The remaining half received identically structured matrices consisting of values from 1 highly salient dimension and of others from a dimension ranked low in salience. The goal in each problem was to select that compound stimulus from a set of alternatives that appropriately filled an empty cell in the matrix. Prior to the matrix problems, half the Ss in each matrix condition received sensitization training designed to increase the salience of the relevant dimensions in the matrix problems. The results showed that the pre-assessed salience of the relevant dimensions affected matrix solution in that more accurate performance was associated with those problems with both relevant dimensions relatively high in salience than those with one high and one low. Although the older Ss solved more problems, the evidence for coordination in the younger Ss was clear. No effects of sensitization training were found. 相似文献
