Children’s Eyewitness Memory for Multiple Real‐Life Events

The present research examined the influence of prior knowledge on children’s free recall, cued recall, recognition memory, and source memory judgments for a series of similar real‐life events. Forty children (5–12 years old) attended 4 thematic birthday parties and were later interviewed about the events that transpired during the parties using the National Institute of Child Health and Human Development protocol. Of the events, half were generic in that they could have occurred at any birthday party, and half were specific to the theme of the party. Older children demonstrated more evidence of using gist‐based information to guide their memory performance than did younger children. However, younger children were able to use global gist to inform their source memory judgments, qualifying past word‐learning research.     

The Development of Children's Memory for the Time of Past Events

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.     

The development of temporal metamemory

In two studies of knowledge about the properties and processes of memory for the times of past events, 178 children from 5 through 13 years of age and 40 adults answered questions about how they would remember times on different scales, how temporal memory is affected by retention interval, and the usefulness of different methods. The adults showed quite accurate knowledge about the main properties of memory for time and the processes that underlie it. Different properties and processes were first understood at ages ranging from 8 years to 12 years or later. Knowledge of the roles of reconstruction and impressions of temporal distances appear well after children use them to remember the times of events.     

Maternal Reminiscing Style During Early Childhood Predicts the Age of Adolescents' Earliest Memories

Individual differences in parental reminiscing style are hypothesized to have long-lasting effects on children's autobiographical memory development, including the age of their earliest memories. This study represents the first prospective test of this hypothesis. Conversations about past events between 17 mother–child dyads were recorded on multiple occasions between the children's 2nd and 4th birthdays. When these children were aged 12–13 years, they were interviewed about their early memories. Adolescents whose mothers used a greater ratio of elaborations to repetitions during the early childhood conversations had earlier memories than adolescents whose mothers used a smaller ratio of elaborations to repetitions. This finding is consistent with the hypothesis that past-event conversations during early childhood have long-lasting effects on autobiographical memory.     

"If it happened, I would remember it": strategic use of event memorability in the rejection of false autobiographical events

The present research investigated the link between perceived event memorability and false-event rejection. In 2 studies, event salience, plausibility, and recency were manipulated. Study 1 showed that high-salience events elicited higher memorability ratings than low-salience events for 5-, 7-, 9-year-olds and adults. Plausibility and recency affected only 9-year-olds' and adults' judgments. Study 2 demonstrated that younger versus older children and adults were less likely to reject false events, and that older children and adults were more likely to reject false events based on salience than were younger children. High-recency false events were more likely to be rejected than low-recency false events. Consistent with prediction, recency moderated the effect of salience. The development of metamemorial awareness and rejection strategies is discussed.     

The development of recognition memory for the left-right orientation of pictures

3 studies examined the development of recognition memory for the left-right orientation of pictures of common objects. In study 1, 5-year-olds, 9-year-olds, and college students were shown 20 pictures of objects. Subsequently, they were tested on their ability to discriminate between 10 of these pictures and their left-right mirror images and between the other 10 pictures and completely new ones. There were large developmental differences in memory for orientation, although all age groups could discriminate accurately between familiar pictures and completely new ones. In studies 2a and 2b, training concerning the relevance of orientation improved second and fourth graders' long-term memory for this characteristic, but training effects were minimal for kindergartners. However, even kindergarten children showed accurate short-term memory for orientation on the task used for training. In contrast to study 2, study 3 produced accurate long-term memory for orientation in kindergarten children by using a verbal training procedure. Results are discussed in terms of the range of memory factors involved in children's mirror-image confusions and in terms of general implications for the development of recognition memory.     

Looking Back to the Future: Māori and Pakeha Mother–Child Birth Stories

Māori adults have earlier first memories than adults in any culture studied to date. To test the role of early memory socialization in this advantage, Māori ( n = 15) and New Zealand European (or Pakeha, n = 17) mothers told birth stories and stories of shared past events to their children (3–4 or 7–8 years). Compared to Pakeha mothers, Māori mothers elaborated more in the birth stories, relative to their elaborations in stories about shared past events, and included more references to relational time and internal states in their birth stories. These data provide the first empirical evidence that Māori children experience a richer narrative environment than Pakeha children for significant events in their past.

Order of information presentation and children's moral judgments.

It was hypothesized that age differences in use of intent information in children's moral judgments might be due to a recency effect in the judgments of younger children. A study was conducted to examine the effect of order of stimulus presentation on children's moral judgments. The information was presented to children, ages 4-5 and 8-9 years old, through stories with either normal information order, intent-consequence, or reversed order, consequence-intent. It was found that order has a significant impact on children's moral judgments. In addition, memory data were gathered which indicated that the pattern of forgetting was parallel to the pattern of information preference for the younger subjects. The findings suggested that younger subjects' relative neglect of intent in the normal order of information was based, in part, on their failure to remember the material correctly rather than on differential weighting of the 2 cues.

Executive functions as predictors of math learning disabilities

In the past years, an increasing number of studies have investigated executive functions as predictors of individual differences in mathematical abilities. The present longitudinal study was designed to investigate whether the executive functions shifting, inhibition, and working memory differ between low achieving and typically achieving children and whether these executive functions can be seen as precursors to math learning disabilities in children. Furthermore, the predictive value of working memory ability compared to preparatory mathematical abilities was examined. Two classifications were made based on (persistent) mathematical ability in first and second grade. Repeated measures analyses and discriminant analyses were used to investigate which functions predicted group membership best. Group differences in performance were found on one inhibition and three working memory tasks. The working memory tasks predicted math learning disabilities, even over and above the predictive value of preparatory mathematical abilities.     

The role of experimenter-odor cues in the performance of object-memory tasks by rats

Two experiments assessed whether odors left on stimulus objects by experimenters who handle them might confound the interpretation of ostensibly visually guided object-memory tasks for rats. In Experiment 1, rats were able to discriminate the relative recency with which an experimenter touched two otherwise identical objects (intertouch interval = 4 sec), presumably on the basis of an odorintensity discrimination. However, after the rats mastered the odor discrimination with no delay between when the second of the two stimulus objects was last touched by the experimenter and when the rats were permitted to attempt the discrimination, their performance dropped to chance levels when this delay was increased to 15 sec. In Experiment 2, rats were trained in two slightly different ways to perform a delayed-nonmatching-to-sample (DNMS) task, one that involved systematic differences in the temporal order in which the experimenter handled the sample and novel stimulus objects and one that did not. There were no significant differences in the rate at which rats mastered the DNMS task with these two procedures, and the performance of rats that were trained according to the former procedure was unaffected when they were switched to the latter procedure. Moreover, rats required considerably fewer trials to master the DNMS task than the rats in Experiment 1 required to master the odor discrimination. These findings demonstrate that, under certain circumstances, rats can discriminate the relative recency with which two objects are handled by an experimenter, but that this ability contributes little to their performance of conventional object-based DNMS tasks.     

The development of children's knowledge of the times of future events

Four studies with 261 children were conducted to describe 4- through 10-year-olds' ability to differentiate the future distances of events. Distances ranged from later the same day through nearly a year in the future. Judgment methods included pointing to parts of a spatial scale representing future distances and answering open-ended questions. Although 4-year-olds failed to differentiate future distances, 5-year-olds were able to distinguish events that would occur in the coming weeks and months from those that would not occur for many months. However, like young children in earlier studies of memory for time, they confused the near future with the recent past. Children 6 through 8 years of age made more differentiated judgments but collapsed the distances of events more than a few months in the future. By 8 to 10 years of age, children accurately judged distances by using mental representations of the times of events in the annual cycle.

Astronomical Concepts and Events Awareness for Young Children

In the present study, we test the effectiveness of a teaching intervention aiming at acquainting children aged four to six years with the concept of the sphericity of the earth and the causes of the phenomenon of day and night. The treatment comprised three units of activities that were developed collaboratively by a researcher and early years teachers employing action research processes. In the present study, student knowledge is considered context specific. The selected approach to learning can be characterized as socially constructed. In the activities, children were presented with appropriate information along with conceptual tools, such as a globe and an instructional video. The activities were implemented in a sample of 104 children of the above age group. Children’s learning outcomes were assessed two weeks after the activities. Assessment tasks comprised children’s construction and handling of concrete 3‐D material models, children’s use of pictures and the globe, and children’s verbal explanations. Results revealed awareness of the concepts and events that the activities dealt with in high percentages of children and children’s storage of new knowledge in the long‐term memory and easy retrieval from it. The outcomes suggest that the approach adopted in the present study is fruitful and promising for helping very young children develop their understanding of fundamental astronomical concepts and events considered difficult for their age and for raising their motivation for astronomy. The approach used in the present study could also find application in other areas of science.

The Effect of Bilingualism on the Measured Intelligence of Elementary School Children of Italian Parentage

The recency of the community college movement has prevented large scale organization and dissemination of knowledge concerning the processes and steps required to establish a community college. There is, therefore, a need for means to incorporate contemporary evidence into the curriculum of prospective administrators of higher education. The purpose of this study was to compare Higher Education Administration students’ peceptions of a logical sequence of events for establishing a community college with a sequence of events for establishing a community college as determined by practice. The Edwards’ matched-pair technique was used to rank the perceptions of the students. A sequence of twenty-nine events was selected from the literature. Each event was matched with every other, thus providing 406 decision situations. From these decisions an ordering was obtained. Using the Spearman rho correlation technique, a coefficient of 0.82 was found between the sequence of events taken from the literature and rank ordering of these events as determined by the Edwards’ matched-pair technique.     

Auditory perceptual processing in reading disabled children

One hundred and three children attending Learning Assistance Centres due to reading difficulties and one hundred and three matched, average readers were administered a battery of auditory perceptual processing tasks. The battery was composed of auditory analysis and synthesis, auditory sequential memory, auditory discrimination, and phonemic segmentation tasks. A principal components analysis yielded four factors. These were determined to be advanced phonological awareness, sequential memory, discrimination, and simple phonological awareness. Discriminant analyses, using the factor scores, indicated that three of the four factors were able to discriminate between the able and disabled readers. Most notable among these was advanced phonological awareness. Auditory discrimination could not discriminate between the groups. The results suggest that there may not be one underlying phonological ability implicated in successful reading acquisition. Furthermore, it is clear that two levels of phonological awareness exist and that screening and diagnostic instruments should address both in order to have predictive validity.     

Taking working memory training from the laboratory into schools

Working memory skills have been shown to be enhanced by adaptive training in several randomised controlled trials. Here, two field trials were conducted in which teachers administered working memory training to their own pupils in school. Twenty-two children aged 8–9?years participated in Trial 1. In Trial 2, 50 children aged 9–11?years with the lowest academic performance completed training. They were matched with a group of 50 children who were not trained. Following training, children in Trial 1 improved significantly in both trained and untrained working memory tasks, with effect sizes comparable to those reported in research studies. Improvements on the trained tasks in Trial 2 were comparable, and training was associated with significantly greater progress at school across the academic year in maths and English. These findings indicate that teacher-administered training leads to generalised and robust gains in working memory and educationally significant gains in academic performance.
