The effects of spatial configuration on preschoolers' attention strategies,selective attention,and incidental learning

This study investigated the effects of spatial arrangement on preschool children's selective attention and incidental learning. Three‐ and four‐year old children were shown a multi‐coloured box designated as a ‘special place’ containing miniature chairs and models of animals. One category of objects were designated as relevant and one as irrelevant. Relevant items were placed in each of the apparatus' corners, in the middle of its walls, or in two corners and in the middle of two walls. Findings revealed that children shown relevant items in corners demonstrated the greatest number of correct relocations for relevant items while those shown relevant items in the middle of the walls showed the greatest number of correct relocations for irrelevant items. Findings also suggest that for both age groups, the ability to recall relevant items may have been independent of their ability to demonstrate a selective attention strategy.

The relationship between preschoolers’ selective attention and memory for location strategies

Late and early preschoolers’ attention and spatial strategies were examined in response to instructions to recall relevant objects [Blumberg, F. C. & Torenberg, M. (2003). The impact of spatial cues on preschoolers’ selective attention. Journal of Genetic Psychology, 164, 42–53] and irrelevant objects [Blumberg, F. C. & Torenberg, M. (in press). The effects of spatial configuration on preschoolers’ selective attention and incidental learning. Infant & Child Development], and to spatial placement of objects within a multi-colored box. Sets of toy chairs or animals were designated as relevant or irrelevant and placed in each of the box's corners (corners condition), in the middle of its walls (walls condition), or in two corners and in the middle of two walls (control condition). Selective attention and spatial strategies were assessed via the removal sequence of items. Recall was assessed via correct relocations of relevant items. Older children and corners condition children showed significantly better recall than children in other conditions. Overall, most children used selective strategies, indicating that relevance of items, rather than their spatial categorization as corners or walls influenced strategy choice.     

The impact of spatial cues on preschoolers' selective attention

The effects of spatial arrangement on preschool children's ability to selectively attend were investigated. Three- and 4-year old children were shown a multicolor dollhouse room intended to serve as a special place containing miniature chairs and models of animals. One category of objects was designated as relevant and 1 as irrelevant. Relevant items were placed in each of the apparatus's corners or in the middle of its walls. Children in the corners condition correctly relocated more relevant items than children in the wall or control conditions. The findings suggest that for both age groups, the ability to recall relevant items may be independent of their ability to demonstrate a selective attention strategy.     

Children's memory of recurring events: is the first event always the best remembered?

Three experiments were conducted to examine the effect of age (4–5 and 6–8 years) and retention interval on children's ability to remember separate occurrences of a repeated event that varied in terms of content (items, dialog, etc.) Experiment 1 explored children's ability to recall the first versus last occurrence of a series of six events, at either one week or six weeks delay. Experiments 2 and 3 explored children's ability to identify the position of items in terms of their order of presentation within the series across two retention intervals. Overall, the results revealed clear age differences in children's performance. In general, the 6‐ to 8‐year‐old children performed better on all tasks than the 4‐ to 5‐year‐old children. Further, the older children showed relatively good memory of the first and last items compared to the middle items, although the last items were more likely to be forgotten or misplaced in the sequencing tasks over time than the first items. For the younger children, the patterns of results were sometimes but not always consistent with that of the older children. The relevance and generalisability of these findings to the legal setting are discussed as well as directions for future research. Copyright © 2002 John Wiley & Sons, Ltd.     

Tell Me Everything You Discussed: Children's Memory for Dyadic Conversations after a 1-Week or a 3-Week Delay

In child abuse investigations, children are often asked to recount previous conversations related to the allegations (i.e., “conversational testimony”). To explore children's ability to provide conversational testimony, we staged a semi-structured novel dyadic conversation between an adult researcher and 8-year-old children (n = 90). Children's gist recall and recognition memory for their own statements, their conversational partner's statements, and question–answer pairs were tested after either a 1-week or a 3-week delay. The results revealed that children recounted a minority of the conversation, although children recalled more after a short delay (7%) than after a long delay (4%). A majority of children's free recall statements were accurate (68%); however, approximately one-third of their free recall statements were incorrect. Children almost exclusively recounted their own statements, and rarely recalled any of the adult's statements or the question–answer pairs during free recall. Reports of the adult's statements and question–answer pairs increased with cued recall questioning, but remained minimal. During recognition testing, children were able to distinguish between true and false recognition items for their own statements and the adult's statements, but performed at chance level on recognition items concerning question–answer pairs. Forensic implications of the results are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Validity of the Children's Picture-Frustration Study: A Social-Cognitive Perspective

We used three studies to examine the validity of hostility scores from the Children's Form of the Picture-Frustration (P-F) Study in the context of Dodge's (1986) social information-processing model of aggression. Dodge's theory states that frustration results in retaliatory aggression only if the frustrated individual attributes hostile intent to the frustrator. Further, differences between aggressive and nonaggressive children in retaliatory aggression are more likely when the frustrator's intent is ambiguous than when the frustrator's intent is dear. In Study 1, items on the Children's P-F Study were rated by 237 children according to how mean they believed the frustrator in each item was. Results showed that items varied significantly in the amount of hostility portrayed. On the basis of these ratings, items were divided into those in which the intent was hostile, nonhostile, or ambiguous. In Studies 2 and 3, we tested Dodge's theory that differences between aggressive and nonaggressive children would be revealed on those items in which the frustrator's intention is ambiguous. In both studies, teachers' ratings of children's retaliatory aggression correlated significantly with the scale comprised of the ambiguous items but not with the scales comprised of the hostile or nonhostile items. The results provide further support to Dodge's theory of aggression and to the use of the Children's P-F Study within a social-cognitive perspective.     

Children's patterns of reasoning about reading and addition concepts

Children's reasoning was examined within two educational contexts (word reading and addition) so as to understand the factors that contribute to relational reasoning in the two domains. Sixty‐seven 5‐ to 7‐year‐olds were given a series of related words to read or single‐digit addition items to solve (interspersed with unrelated items). The frequency, accuracy, and response times of children's self‐reports on the conceptually related items provided a measure of relational reasoning, while performance on the unrelated addition and reading items provided a measure of procedural skill. The results indicated that the children's ability to use conceptual relations to solve both reading and addition problems enhanced speed and accuracy levels, increased with age, and was related to procedural skill. However, regression analyses revealed that domain‐specific competencies can best explain the use of conceptual relations in both reading and addition. Moreover, a cluster analysis revealed that children differ according to the academic domain in which they first apply conceptual relations and these differences are related to individual variation in their procedural skills within these particular domains. These results highlight the developmental significance of relational reasoning in the context of reading and addition and underscore the importance of concept‐procedure links in explaining children's literacy and arithmetical development.     

THE EFFECTS OF PARENT‐IMPLEMENTED PECS TRAINING ON IMPROVISATION OF MANDS BY CHILDREN WITH AUTISM

The present study examined the extent to which mothers were able to train their children, 2 boys with autism, to exchange novel pictures to request items using the picture exchange communication system (PECS). Generalization probes assessing each child's ability to mand for untrained items were conducted throughout conditions. Using a multiple baseline design, results demonstrated that both children improvised by using alternative symbols when the corresponding symbol was unavailable across all symbol categories (colors, shapes, and functions) and that parents can teach their children to use novel pictorial response forms.     

Children's dietary recalls from three validation studies: types of intrusion vary with retention interval

Using previously collected data of fourth‐grade children observed eating school meals and then interviewed, we categorized intrusions (food items reported but not observed eaten) as stretches (on the child's tray) or confabulations (not on the child's tray). We investigated intrusions, confabulations, and stretches and the role of liking, at different retention intervals (morning interviews about the previous day's intake; evening interviews about that day's intake) and under different reporting‐ order prompts (forward; reverse). As retention interval between consumption and report increased, the likelihood (1) increased that reported items were intrusions, that reported items were confabulations and that intrusions were confabulations; and (2) was constant that reported items were stretches. Results concerning reporting‐order prompts were inconclusive. Liking ratings were higher for matches (reports of items observed eaten) than stretches, for confabulations than stretches, and for matches than omissions (unreported items observed eaten), but did not vary by retention interval or reporting‐order prompts.

Effects of Motivation on Young Children's Object Recall and Strategy Use

The study was designed to examine the effects of motivation on young children's recall for object names and early-emerging mnemonic activities. Seventy-two 4-year-old children were randomly assigned to 1 of 3 instructional conditions: incidental, intentional, or motivational. Each child was shown 10 small toy objects and provided a 90 s study period prior to recall. The children's mnemonic behaviors were videotaped for subsequent coding. The children in the incidental condition were instructed to simply look at the toys while children in the intentional and motivational condition were given explicit instructions to remember. The motivational group was also told that they could keep whichever toys they remembered. A recognition memory task was employed to examine the extent to which the stimuli were encoded during the study period. The children's recall memory did not vary as a function of instructional condition. Children's use of singular versus multiple strategies was calculated, along with a weighted summary score giving most weight to the participant's use of mature mnemonic strategies. Significant differences in strategy use were found, favoring the motivational condition. Significant positive correlations were found between the weighted summary scores and object recall, and the teacher ratings of mastery motivation and object recall. Mastery motivation was found to be unrelated to the strategic summary scores, failing to mediate strategic behaviors. The results suggest that when providing incentives to remember, children apparently engaged in more effortful mnemonic processing in order to remember the items, even though a greater number of items were not recalled.     

A Scale for Measuring Persistence in Children

Persistence and its assessment have been studied since the 1920s. One common approach in measuring persistence has been through testing the subject's ability to solve difficult or monotonous problems. Another approach has been through questionnaires. Although persistence is very important in academic achievement and in the general development of personality, no questionnaires have been developed for measuring persistence in children. The present research concerns the development of such a scale. It includes 40 items and was tested on 322 Israeli children aged 7-13. The internal reliability of the scale (Cronbach alpha) was .66, and the test-retest reliability after 6 months was .77. The scale differentiated active gymnasts from nongymnasts as well as persistent gymnasts from dropout gymnasts. In addition, significant correlations were found between the scale and the need-persistence measure of the Rosenzweig Picture Frustration Study, Locus of Control, and other measures. We discuss these findings along with the significance of persistence in everyday life.     

Using Toys and Models in Interviews with Young Children

The present study examined the conditions under which toys and model items facilitate children's accounts of personally experienced events. In three experiments, 109 five- to six-year-old children were interviewed about an event in which they had participated. Experiment 1 varied the similarity of the props to the items from the event while Experiments 2 and 3 varied the number of model items and the method of their presentation. Results showed that increasing the physical similarity of the props to items from the event, adding spatial layout cues, or increasing the number of props provided enhanced the facilitative effects of props on children's accounts. The implications of these results for interviewing children in clinical and legal contexts are discussed. © 1997 by John Wiley & Sons, Ltd.     

Two-and-a-Half-Year-Olds’ Memory for Sources of Actions: Contextual Support Facilitates Recall

This research examines the early emergence of source-monitoring abilities. Previous research has consistently demonstrated that children as young as 3 to 4 years of age do well on simple versions of action-based source-monitoring tasks. Research on even younger children, however, remains lacking. In this study we examined whether 2½-year-olds could accurately recall source on a simplified task. For the procedure, we used an action-based task in which children collaborate with an experimenter to build a model farm. During construction, the child and the experimenter took turns placing items on the farm. After construction, children were administered a source memory test in which they were asked to recall who had placed each item. To more closely examine factors that influence source accuracy in this young population, we included two conditions that varied in terms of contextual support. In the no-context-cues condition, in line with typical source-monitoring tasks, children were asked the source test question while items were presented individually and the farm was not in view. In the context-cues condition, the original spatial array of farm items was left intact to provide additional cues for children's source decisions. The main finding was that children in both conditions showed high levels of source accuracy at test indicating a surprisingly early age of emergence for this ability. Also, as predicted, children in the context-cues condition were the most accurate in attributing source.     

The adaptive nature of children's overestimation in a strategic memory task

Kindergarten, first-, and third-grade children were given a multitrial sort-recall task with different items on each trial. Children were asked to predict how many items they would recall prior to each trial. We classified children into high- and low-overestimation groups based on their prediction accuracy on the first two trials and assessed changes in recall and strategy use over trials (trials 4/5 minus trials 1/2). Following predictions, at all grades, children in the high-overestimation group showed greater gains (or fewer losses) in recall than children in the low-overestimation group. Differences in strategy use over trials were generally nonsignificant. The results were interpreted as reflecting the adaptive nature of children's overestimation of their cognitive abilities.     

Verbal fluency in children with ADHD: Strategy using and temporal properties

Verbal fluency tasks are commonly used in cognitive and developmental neuropsychology in assessing executive functions, language skills as well as divergent thinking. Twenty-two typically developing children and 22 children with ADHD between the ages of 8 and12 years were examined using verbal fluency tasks, prepotent response inhibition, and working memory tests. The clinical group showed impaired inhibitory and spatial working memory processes. We used different qualitative analyses of verbal fluency tasks to explore the lexical and executive strategies (word clustering and switching), and the temporal properties of the responses. Children with ADHD had a leeway in applying relevant lexical or executive strategies related to difficulties in strategy using. The reduced efficiency of children with ADHD in semantic fluency task is based on suboptimal shifting between word clusters and is related to the lack of ability of producing new clusters of items. The group difference appeared at the level of accessing and/or activating common words; however, the executive process of searching the lexicon extensively is intact.

Selective processing in encoding and memory: an analysis of resource allocation by kindergarten children.

This study investigated the extent to which kindergarten children (mean age 5.8 years) allocate their processing resources selectively to the relevant components of a visual array. On each trial the child was presented with an array containing either one, two, or four items, and a verbal cue designating either one, two, or four of these items as relevant. For different groups of children the cue occurred either before or after the stimulus array, in order to investigate the stages of processing at which kindergarteners are able to initiate selection. The results indicated that kindergarteners are able to exert considerable control over the allocation of resources during the initial perceptual processing of a visual stimulus, but they have only limited ability to initiate such selective allocation in memory, after initial encoding has taken place.     

First Principles Organize Attention to and Learning About Relevant Data: Number and the Animate-Inanimate Distinction as Examples

Early cognitive development benefits from nonlinguistic representations of skeletal sets of domain-specific principles and complementary domain-relevant data abstraction processes. The principles outline the domain, identify relevant inputs, and structure coherently what is learned. Knowledge acquisition within the domain is a joint function of such domain-specific principles and domain-general learning mechanisms. Two examples of early learning illustrate this. Skeletal preverbal counting principles help children sort different linguistic strings into those that function as the conventional count-word as opposed to labels for objects in the child's linguistic community. Skeletal causal principles, working with complementary perceptual processes that abstract information about biological and nonbiological conditions and patterns of movement, lead to the rapid acquisition of knowledge about the animate-inanimate distinction. By 3 years of age children con soy whether photographs of unfamiliar nonmammalian animals, mammals, statues, and wheeled objects portray objects capable or incapable of self-generated motion. They also generate answers to questions about the insides of animate items more readily than ones about the insides of inanimate items. Although these children already ore articulate about matters relevant to a theory of action, their limited knowledge of growth illustrates that early skeletal principles do not rule out the need to acquire new principles, in this case ones that underlie a biological account of animacy (Carey, 1985).     

Enhanced discrimination in autism

Children with autism are superior to typically developing children at visual search tasks (O'Riordan, Plaisted, Driver, & Baron-Cohen, in press; Plaisted, O'Riordan, & Baron-Cohen, l998b). This study investigates the reasons for this phenomenon. The performance of children with autism and of typically developing children was compared on a series of visual search tasks to investigate two related problems. The first issue was whether the critical determinant of search rate in children is the discriminability of the display items, as it is in normal adults. The second question investigated was whether the superior performance of individuals with autism on visual search tasks is due to an enhanced ability to discriminate between display items. The results demonstrated that discriminability is the rate-determining factor for children with and without autism, replicating earlier findings with normal adults, and that children with autism have an enhanced ability to discriminate between display items. Thus, it seems that an enhanced ability to discriminate between display items underlies superior visual search in autism.
