A systematic literature review of math interventions across educational settings from early childhood education to high school
Early math skills lay the foundation for children’s long-term academic success. An increasing number of randomized controlled math interventions have been carried out across educational settings. The aim of the present systematic review was to identify the distribution of the randomized controlled math interventions conducted between 2001 and 2021 in educational settings across Early Childhood Education (ECE) up to high school among various sampl…
On the importance of contextual cues for spontaneous recall in 35- and 46-month-old children
Recent evidence shows that returning to the same distinct lab setting after 1 week triggers spontaneous memories in 35- and 46-month-old children. However, it remains unclarified which specific cues are triggering spontaneous recall. We report two experiments in which distinct contextual cues were altered between encoding and test. In Experiment 1 (N = 76), the color of the box containing the event props was changed. Despite this change, the chil…
To ask or not to ask
Children's ability to intentionally recall events lessens with temporal distance to the occurrence. However, little is known about the effects of retention time on memories that emerge spontaneously. We examined spontaneous and strategic retrieval in eighty-one 46-month-olds' memory of a lab event after 1 week (the 1-week Condition) versus 43 weeks (the 43-week Condition) in a between-subjects design, using well-established procedures (Krøjgaard …
Gender differences in emotional reminiscing in a Scandinavian sample
Emotional reminiscing is a context where children learn culture‐specific ways of understanding past emotional experiences through parentally scaffolded conversations, and learn how to connect these disparate experiences into their developing autobiographical memory. The goal of the present investigation was to explore possible gender differences in emotional reminiscing in an egalitarian cultural context (Denmark). Mothers and fathers from famili…
Distinct environmental cues trigger spontaneous recall of past events in 3- and 4-year-old children even after long delays
Verbally reported long-term memory for past events typically improves with age. However, such findings are based exclusively on studies, where children are directly asked to recall. The present study showed that when 3- (n = 113, 59 girls) and 4-year-olds (n = 113, 62 girls), predominantly White, were brought back to a distinct laboratory-setting after either 1-, 4.5-, or 13-weeks, children—regardless of age and delay—spontaneously recalled the d…
Spontaneous verbal recall
Noting a difference
An experimental paradigm has shown that it is possible to activate spontaneous memories in children by having them re-visit the setting in which they were introduced to a memorable event. Nevertheless, the most important cues for spontaneous recall remain undetermined. In response, we investigated the importance of the experimenter by introducing 35-month-olds (n = 62) and 46-month-olds (n = 62) to the same or a new person after one week. We expe…
Gender and parental involvement in parent‐child reminiscing in a Scandinavian sample
Despite the extensive bulk of literature on maternal reminiscing style, only a handful of reminiscing studies have investigated gender differences in parental reminiscing style, with none of these studies having explored the possible relationship between parental involvement level and parental reminiscing style. The current study investigated gender differences in parental reminiscing style across positive and negative event types in an egalitari…
Towards a detailed understanding of preschool children’s memory-related functioning and emotion regulation
This study examined the role of parents' reminiscing style in preschoolers' memory-related functioning and general emotion regulation. In 87 families, each parent rated their child's ( M age = 4.07 years, SD = 0.80) emotion regulation and discussed a positive and a negative memory with their child (resulting in 275 conversations). Multilevel analyses showed that children's rated engagement during the conversation was higher when parents were obse…
Eight-year-olds, but not six-year-olds, perform just as well as adults when playing Concentration
Anecdotal reports suggest that children often outperform adults when playing Concentration. This is surprising as cognitive processes tend to develop progressively throughout childhood. To date, very few studies have examined this apparent paradox, and with mixed results. In the present study, the ability of 6-year-olds (n = 34), 8-year-olds (n = 48), and adults (n = 38) to play Concentration was examined in a controlled computer-based setup invo…
By-passing strategic retrieval
On the Theorem of Correspondence
In a recent paper, Mammen (Integrative Psychological and Behavioral Science, 50, 196-233, 2016a) brought novel arguments into the discussion concerning the importance of being able to single out and track objects through space and time. Mammen offered a formal account of two basic, yet distinct, ways in which we as human beings encounter objects in the real world, that is, sense and choice categories. In this paper I discuss aspects of his theory…
Occlusions at event boundaries during encoding have a negative effect on infant memory
Empty Looks or Paying Attention? Exploring Infants' Visual Behavior during Encoding of an Elicited Imitation Task
Recently, there has been an increased interest in the relationship between looking time during encoding and subsequent memory performance in imitation tasks. Hitherto, the results have been inconclusive: one line of research supporting the link between looking time and performance and another line finding no relation. The existing studies may, however, have been restricted by using small samples, limited looking time measures, and short retention…
Keeping Track of Individuals
According to Mammen and Mironenko (2015) our sensitivity to objects' history (i.e., objects' whereabouts across space and time) has been neglected in much of contemporary psychology. In this paper I present evidence from a developmental psychological perspective indicating that although the terminology is different, some research concerning these important issues has actually been conducted. First, research primarily under the heading 'essentiali…
Adults’ earliest memories of songs and melodies based on a large stratified sample
Most parents sing to their children. Yet, little is known regarding how early musical experiences are retained later in life. This study is a first attempt to fill this gap in the literature. Based on the stratified sample, we asked 973 adults about their first memories of a song or melody. The results revealed that adults’ earliest memories of a song or melody generally were predated by memories for other events; thus, the music memories were no…
The magic shrinking machine revisited
In a seminal study Simcock and Hayne (2002) showed that 3-year-olds were unable to use newly acquired words to describe a "magic" event experienced 6 or 12 months earlier. In the reference study the children's verbal recall was tested without props being present. Inspired by recent evidence, the original design was replicated, testing 33-and 39-month-olds (n = 180), but with props present at recall while controlling for potential online reasoning…
Three-year-olds’ memory for a person met only once at the age of 12months
This study examined three-year-olds' verbal and non-verbal memory for a person met only once after a 28 month interval. Children in the Test group (N=50) had participated in an earlier experiment at our lab at the age of 12 months where they met one of two possible experimenters. At this past event half of the children were tested by one, the other half by the other experimenter. At the follow-up, run by a naïve experimenter, the children were sh…
“That one makes things small”
We introduce a new method for examining spontaneous (unprompted) autobiographical memories in 3.5-year-old children, by inducing them in a laboratory setting. Thirty-eight 3.5-year-olds, who had previously participated in a study in our lab involving highly unique props, were brought back after a one-month delay to the same lab arranged as in the original study and with the same Experimenter present. While waiting for the Experimenter in front of…
