Children's uncertainty about the interpretation of ambiguous messages

Three investigations were made into relationships between children's uncertainty about the correctness of their interpretation of an ambiguous message, and their judgment of the quality of that message. In the first two investigations, we compared one condition under which 5-to 6-year-olds made a single interpretation of an ambiguous message, with another condition under which they could make both possible interpretations. It was found that making both interpretations had no effect on children's confidence about the correctness of a particular one of the interpretations. Children who made both interpretations were often confident about the correctness of one of them. In the second investigation, we found that children who were uncertain about the correctness of one particular interpretation, did not necessarily realize that they could not tell which of the two possible interpretations was correct. They did not necessarily recognize the ambiguity in the message. In the third investigation, we identified children who correctly identified messages as ambiguous after they knew that they had made the wrong interpretation, but who were confident of the correctness of their interpretation of ambiguous messages before they knew the outcome. Hence awareness of uncertainty when making an interpretation may not be necessary for the development of understanding ambiguity. The results are discussed in terms of the significance of the child's awareness of uncertainty for development of understanding about message ambiguity.     

Knowing when you don't know enough: Children's judgements about ambiguous information

Two experiments were carried out to find out whether young children's failure to realise when messages are ambiguous is specific to verbally transmitted information about a person's intended meaning. In Experiment 1, children judged whether they had been told/shown enough to identify which one of a set of cards the experimenter had chosen. In one game the experimenter gave verbal messages about her chosen cards, and in a second game, she gave visual messages. With ambiguous visual messages, relevant parts of cards were physically covered. We expected that this would make it more obvious that the speaker's intended meaning was not being fully conveyed. No difference was found between verbal and visual conditions: correct judgements about message ambiguity occured with the same frequency in both.In Experiment 2, children judged in one game whether they had been told enough about the experimenter's chosen card, as in Experiment 1. In a second game, visual information about a card was not conveyed by the experimenter, Rather, the child operated a pointer, set in a disc with windows, beneath which lay cards. The child judged whether the window showed enough for him/her to tell which card the pointer indicated. Again, correct judgments about ambiguity occured with the same frequency in both games.The results implied that children's failure to realise when verbal messages are ambiguous is but one aspect of a more general failure to realise when one has insufficient information at one's disposal to guarantee a correct interpretation of what the world is like.     

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.     

The eyes have it: Young children's discrimination of age in masked and unmasked facial photographs

The ability of preschool children to discriminate age, and their use of information from different facial areas in this task, was investigated. Most 4-year-olds were able to rank sets of seven facial photographs into age order successfully. Subsequently, they were presented with facial stimuli in which different regions of the face were masked out. Masking of the eyes produced a marked performance decrement, and masking of the nose and cheeks a slight decrement, relative to masking of either the mouth and chin, or of the hair and neck. Possible explanations of the results are discussed, together with the verbal comments of the children on the cues they were aware of using.     

The influence of prosody on the recall of monaurally presented sentences.

Semantically anomolous sentences, which were spoken prosodically or in an even monotone, were presented monaurally and recalled after 5 sec of interpolated counting. Recall was superior in the Prosody condition, and performance in the Monotone condition showed no improvement when subjects were given prior knowledge of the syntactic structure. Also, a right ear advantage was found in the Prosody condition. The influence of prosody was attributed to its role in directing attention and providing continuity during memorization of the sentences, this being more effective when the information was received by the language hemisphere from the right ear.     

Young children's understanding of displaced aggression

According to previous research, young children do not understand displaced aggression. The present study examines the early phases of the understanding of the causes of moderately and extremely displaced aggression. Preschool and kindergarten children (3 to 5 years of age) viewed eight videotaped episodes of displaced aggression. Their comprehension of this aggression was assessed by means of open ended questions and forced choice picture selections. By age 5 most children had some understanding of displaced aggression, but this understanding was not complete. The early understanding revealed in the present study may be due to the use of short, simple realistic videotaped episodes appropriate for the limited processing abilities of young children. Extreme displacement was not more difficult to understand than moderate displacement.     

Kindergarten children's use of category membership

Kindergarten children (N = 70) learned to order 12 photographically presented objects. The objects were well known and either unrelated or categorizable into two, three, four, or six well-known categories. Free recall was assessed. Results indicated that the children used category membership both to learn and to recall the items. However, they processed the list composed of six pairs of items at least as efficiently as lists composed of fewer but larger groups of items (including a list indexed as easiest through previous adult performance).     

Effects of spacing repetitions on children's memory

Two experiments examined the effect of spacing repetitions within a word list on the free recall performance of elementary school children. In the first experiment, spacing repetitions facilitated recall, and the function relating recall of repeated items to the spacing between repetitions was the same throughout the age range investigated (first, third, and sixth graders). But, the function for these elementary school children reached asymptote at a much shorter spacing than the function typically reported for adults. The second experiment was designed to test an encoding variability explanation of spaced-repetition effects in elementary school children. Results for both third- and sixth-grade children were consistent with the hypothesis that differential encoding of repetitions facilitates performance and that spaced repetitions are remembered better because they are more likely to be differentially encoded. A theoretical framework was discussed that may be able to encompass both these results and another finding in the literature which indicates that differential encoding can sometimes impair rather than facilitate children's memory performance.     

Development of children's ability to judge relative numerosity

Three- to seven-year-old chilren were trained through reinforcement to select either the more or less numerous of two rows of squares. One group was shown rows in which number covaried with row length, one group saw rows in which number covaried with row density, and a third group saw rows in which number did not covary with other dimensions. The children's operational stage was assessed by a number conservation test. All children successfully judged relative numerosity when number covaried with length or with density, but only concrete operational children were successful when number did not covary with other dimensions. Preoperational children are thus not able to base judgments of relative numerosity solely on number.     

Infant search tasks reveal early concepts of containment and canonical usage of objects

It is difficult to gain unambiguous evidence on the use of concepts by infants. Many results can be accounted for in terms of action-based strategies. The evidence reported here fulfils the minimal criteria for the operation of working concepts in infants. Search tasks are used with a filled interval which forces memory-search, and the object is hidden in containers which fulfil their customary job or violate it. Infants treat an upright cup as a more reliable location marker than an inverted one. A series of experiments probes the phenomenon. The results indicate that the infants have a working concept of containment which can be triggered by the provision of containers in their canonical orientation. Even “object permanence tasks” lead infants to access their knowledge of the relationships into which things typically enter in the world outside the laboratory.     

Factors affecting the acquisition and elimination of children's donating behavior

Thirty-five 6- to 10-year-old children with initial low rates of donating to help a peer either simply received a fine for each failure to donate (n = 7) or also were informed of the contingency between the fine and failure to donate (n = 28). Explanation of the contingency was necessary to increase children's donation rates. Donations continued at high rates during a gradual, unannounced removal of the fine contingency, but decreased when children were informed that fines were no longer in effect, particularly for children who had failed to donate at least once during training and had actually been fined. Overall, addition of a distraction or an inequity procedure did not reduce donating below rate reductions due to the announced extinction procedure alone.     

Spatial depth relationships in young children's drawings

Previous research suggests that young children do not attempt to represent depth relationships between objects in their drawings. The present study, however, showed that when both objects are visible and the children's attention is drawn to the depth relationship between them, most 5-, 6-, and 7-year-olds do attempt to portray this relationship.     

Effects of hierarchical organization on children's judgments of distance and direction

The impact of the hierarchical organization of a space on judgments of direction and distance was assessed in two studies using two-dimensional models analogous to those used by A. Stevens and P. Coupe (1978, Cognitive Psychology, 10, 422–437). In each study the models contained two stars and were divided into two parts by a curved boundary line. In the Homogeneous condition the stars were located in the same subsection. In the Congruent condition the leftmost star was in the left subsection and the rightmost star was in the right subsection. In the Incongruent condition the rightmost star was in the left subsection and the leftmost star was in the right subsection. In Experiment 1 first graders, third graders, and college students were required to remember the location of the stars. Results indicated that the first and third graders tended to use the relationship between the subsections as a clue to the relationship between the sites within them, thus extending the results of Stevens and Coupe (1978) to children. In Experiment 2 preschoolers, first, and third graders were asked to judge with the materials directly in front of them, which of the two stars was closer to a site located in one of the subsections. Results indicated that the Incongruent condition led to errors among the preschoolers and first graders but not the third graders, thus indicating that these groups tended to judge as closer the site within the same subsection even though it was really farther away. The results of both studies are discussed as indicative of a tendency among young children to impose organization on information encoded in memory and in relation to increases in metric accuracy, decentration, and efficient scanning which enable them to more accurately evaluate when such organization is and is not appropriate. Implications for behavior in large-scale environments are also discussed, with particular reference to the effect of barriers on perceptions of distance and direction.     

The effects of review on young children's memory for prose

The present study investigated the effects of review on young children's memory for prose. Prose passages were parsed into three levels of thematic importance. Five groups (128-year-old children each) participated in three experimental sessions, with each session separated by 1 week. During the first session all subjects listened to two passages. One week later, subjects in four of the groups received differing review experiences. During the third session, delayed retention was assessed. The data are interpreted to indicate that the repetition of the original learning experience was the most effective review; however, immediate reproduction following initial exposure also significantly attenuated forgetting. All groups favored the central passage ideas in their delayed recalls, regardless of their review treatment. The potential benefits of an immediate test as a review exercise was suggested.     

Part-whole transfer and organization in children's and adults' multitrial free recall

The effect of age-related differnces in the use of recall organization on the amount of recall and the properties of recall-acquisition patterns obtained in a multitrial part-whole transfer task was investigated among subjects in grade levels 1, 4, 7, and college (ages 6.5, 9.6, 12.6, and 19.7 years, respectively). Half of the subjects receiving relevant and irrelevant part lists sorted stimuli before recall trials; other subjects studied the items as they were presented, one at a time. Relevant part list learning was equally facilitative for all age groups regardless of presentation condition, and despite the greater amounts of recall organization found among college subjects. All age groups showed trial-to-trial improvements in whole-list recall; however, only the college subjects showed corresponding improvements in clustering, and all age groups had high rates of fluctuation in the composition of their recall from trial to trial. It was concluded that while even the limited amounts of spontaneous recall organization found among children are sufficient to enhance recall, organization is not a necessary condition for recall improvement and not the primary means by which children throughout the preformal-operations period increase their recall of unrelated stimuli over trials in a free-recall task.     

A response set analysis of developmental differences in children's moral judgments

The study tested the hypotheses that 1) children may not adopt a moral response set when faced with moral dilemmas and 2) their knowledge of what constitutes a moral constellation of behaviors may differ from that of adults and may lead to developmental differences. To test these hypotheses, the study examined children's responses to a multiple choice moral dilemmas questionnaire under neutral instructions, instructions to answer as a good child or as a bad child. Subjects in fourth and seventh grade were asked whether a story hero would transgress and were required to justify their answers. In addition, questions regarding affective reactions to transgressions, confessions, and due punishment were asked. Fourth grade children answering in the good child instructions condition tended to give significantly different responses than under neutral instructions, while seventh grade subjects did not tend to differentiate between these two instruction conditions. While adult theories of morality would predict a differentiation between good and bad child instructions, on some of the measures no differences were found between good and bad child instructions. The implications of these results for cognitive-developmental theory were discussed and a general framework for interpreting the data was offered.     

The air gap phenomenon in children's landscape drawings

The “air gap” phenomenon was found to be very common in the free landscape drawings of middle and later childhood. Three experiments are reported in which the contextual cues for such drawings were systematically manipulated. When subjects were supplied with drawing sheets constructed to imply the absence of the air gap, the phenomenon was eliminated in most of their drawings. When supplied with sheets constructed to imply its presence, most subjects produced air gap drawings using contextually provided reference lines. There were no consistent transfer effects across different cuing orders. The susceptibility of the air gap phenomenon to modification by task manipulation suggests that it results from problems of production rather than from defects in the child's internal representation of the world.     

Assessment of children's social skills

Various methods of social skills assessment with children were reviewed. Based upon an extensive review of the literature, it was found that behavioral observations, sociometrics, and teacher ratings have been the most often used methods of assessing children's social skill deficits. Advantages and disadvantages of each assessment technique were discussed within a psychometric and social validation context. Conclusions were that school psychologists should utilized all three measures to secure a comprehensive picture of children's social behavior and to obtain some measure of social validation.
