Executive functioning and prospective memory in young children

The current study examined the role of executive functioning (EF) in children's prospective memory (PM) by assessing the effect of delay and number of intentions to-be-remembered on PM, as well as relations between PM and EF. Ninety-six 4-, 5-, and 6-year-olds completed a PM task and two executive function tasks. The PM task required children to interrupt an ongoing card game to perform one action (single intention) or two actions (dual intention) with target cards after a short delay (1 min) or a long delay (5 min). There was no main effect of number of intentions or delay on the PM task. However, performance improved with age, and age and delay interacted such that 4-year-olds’ performance remained the same after a long delay whereas 5-year-olds’ performance improved after a long delay. We suggest that the age by delay interaction is a product of age differences in cognitive monitoring. Working memory but not inhibitory control predicted PM with age controlled. We argue that an executive function framework permits an integrative understanding of many processes involved in young children's prospective memory.     

Individual differences in young children's suggestibility: Relations to event memory,language abilities,working memory,and executive functioning

In this paper, two empirical studies are presented in which an attempt was made to explain individual differences in two different aspects of 4-year-olds’ suggestibility, that is, their ability to resist false suggestions and memory impairments due to prior misinformation. As sources of individual differences cognitive skills along the information processing pathways were chosen: executive functioning (Study 1) and working memory (Study 2). Additionally, memory for the observed event and language proficiency were included in the studies. The results revealed that overall individual differences in language skills made a significant and consistent contribution to individual differences in the included measures of children's susceptibility to suggestions. Executive function and working memory skills were not directly related to children's tendency to yield false suggestions and their memory impairments in a recognition test after being misled. However, both executive function and working memory were related to children's language proficiency pointing to a possible indirect effect and underlining the importance of language competencies in early childhood.     

Reconsidering Advertising Literacy as a Defense Against Advertising Effects

It is widely assumed that advertising literacy makes children less susceptible to advertising effects. However, empirical research does not provide convincing evidence for this view. In this article, we explain why advertising literacy as it is currently defined (i.e., conceptual knowledge of advertising) is not effective in reducing children's advertising susceptibility. Specifically, based on recent insights on children's advertising processing, we argue that due to the affect-based nature of contemporary advertising, children primarily process advertising under conditions of low elaboration and, consequently, are unlikely to use their advertising knowledge as a critical defense. Moreover, literature on cognitive development suggests that children's ability to use advertising knowledge as a defense will be further limited by their immature executive functioning and emotion regulation abilities. Therefore, we argue that the current conceptualization of advertising literacy needs to be extended with two dimensions: advertising literacy performance, which takes into account the actual use of conceptual advertising knowledge, and attitudinal advertising literacy, which includes low-effort, attitudinal mechanisms that can function as a defense under conditions of low elaboration. We conclude our article with specific directions for future research and implications for the ongoing societal and political debate about children and advertising.     

Involvement of Executive Functions in Children's Metamemory

This experiment examined how knowledge of memory strategies and of memory functioning improves during childhood and what variables are involved in this development. Three main aspects of metamemory were assessed based on the performance of a group of 100 children (aged 4, 6, 9 and 11 years) on a battery of executive tasks. At the same time, the influence of variables such as intelligence, vocabulary and parental education level was also investigated. Results of mediation analyses reveal that the relation between children's age and internal strategy knowledge was partially mediated by working memory skills but that executive functions did not mediate the impact of chronological age on children's knowledge of external strategies or of memory functioning. Additionally, verbal fluency predicted internal and external strategy knowledge. Implications for general learning theories in childhood are discussed.Copyright © 2015 John Wiley & Sons, Ltd.     

Exposure to intimate partner violence and children's psychological adjustment,cognitive functioning,and social competence: A review

Research over the past 30 years has established that exposure to intimate partner violence poses significant risks to children's adjustment and functioning. It is also clear, however, that there is considerable variability in children's outcomes, and research in the past decade has increasingly focused on understanding this variability. This paper provides a review of recent research that examines relations between children's exposure to intimate partner violence and their psychological adjustment, cognitive functioning, and social competence. Emphasis is placed on studies that examine risk and protective factors for children's functioning in the context of exposure to intimate partner violence. In addition to highlighting strengths of recent studies, limitations of existing research and future directions are considered.     

Long-Term Executive Function Deficits in Children With Traumatic Brain Injuries: Assessment Using the Behavior Rating Inventory of Executive Function (BRIEF)

Long-term deficits in executive functions following childhood traumatic brain injuries (TBI) were examined using the Behavior Rating Inventory of Executive Function (BRIEF). Parents completed the BRIEF approximately 5 years postinjury as part of a prospective study of children injured between the ages of 6 and 12. The children were between 10 and 19 years of age at the time of the assessment, and included 33 with severe TBI, 31 with moderate TBI, and 34 with orthopedic injuries. Parents also rated children's adaptive functioning and completed several other measures of parent and family functioning. Children were administered a neuropsychological test battery that included several measures of executive functions. The groups displayed a significant linear trend in BRIEF scores, with the largest deficits in executive functions reported in children with severe TBI. BRIEF scores were related consistently across groups to a test of working memory, but not to other neuropsychological measures. BRIEF scores also predicted children's adaptive functioning and behavioral adjustment, as well as parent psychological distress, perceived family burden, and general family functioning. The findings indicate that TBI results in long-term deficits in executive functions that are related to children's psychosocial outcomes, as well as to parent and family functioning.     

A bilingual advantage for episodic memory in older adults

The ability to remember events—referred to as episodic memory—is typically subject to decline in older adulthood. Episodic memory decline has been attributed in part to less successful executive functioning, which may hinder an older adult's ability to implement controlled encoding and retrieval processes. Since bilingual older adults often show more successful executive functioning than monolinguals, they may be better able to maintain episodic memory. To examine this hypothesis, we compared bilingual and monolingual older adults on a picture scene recall task (assessing episodic memory) and a Simon task (assessing executive functioning). Bilinguals exhibited better episodic memory than their monolingual peers, recalling significantly more items overall. Within the bilingual group, earlier second language acquisition and more years speaking two languages were associated with better recall. Bilinguals also demonstrated higher executive functioning, and there was evidence that level of executive functioning was related to memory performance. Results indicate that extensive practice controlling two languages may benefit episodic memory in older adults.     

The Contribution of Executive Function to Source Memory Development in Early Childhood

Age-related differences in episodic memory judgments assessing recall of fact information and the source of this information were examined. The role of executive function (EF) in supporting early episodic memory ability was also explored. Four- and 6-year-old children were taught 10 novel facts from two different sources (experimenter or puppet), and memory for both fact and source information was later tested. Measures of working memory, inhibitory control, and set shifting were obtained to produce an indicator of children's EF. Six-year-olds recalled more fact and source information than did 4-year-olds. Regression analyses revealed that age, language ability, and EF accounted for unique variance in children's fact recall and source recall performance. These findings suggest a link between episodic memory and EF, and we propose that developmental investigations should further explore this association.     

From terrible twos to sassy sixes: The development of vocabulary and executive functioning across early childhood

Across the early childhood period of development, young children exhibit considerable growth in their executive functioning (EF) and vocabulary abilities. Understanding the developmental trajectory of these seemingly interrelated processes is important as both early vocabulary and EF have been shown to predict critical academic and socio-emotional outcomes later in childhood. Although previous research suggests that EF and vocabulary are correlated in early childhood, much of the existing longitudinal research has focused on unidirectional relations among preschool child samples. The current large-scale study, therefore, sought to examine whether children's vocabulary and EF abilities are bidirectionally related over time across four measurement waves in early childhood (i.e., at ages 2, 3, 4, and 6). At each timepoint, children's vocabulary skills were positively correlated with their concurrent EF abilities. After controlling for child sex and maternal education status, the best-fitting, cross-lagged panel model was a unidirectional model whereby children's early vocabulary scores predicted their later EF performance at each timepoint. Although age 2 EF significantly predicted age 3 vocabulary size, this association was no longer significant after accounting for maternal education status. Our results illustrate that vocabulary size plays an important role in predicting children's later EF performance across various timepoints in early childhood, even after controlling for children's initial EF scores. These findings have important implications for intervention research as fostering early vocabulary acquisition may serve as a possible avenue for improving EF outcomes in young children.

Research Highlights

• Children's vocabulary size is positively correlated with their concurrent executive functioning skill at ages 2, 3, 4, and 6
• Young children's early vocabulary scores predict their later EF performance across measurement waves, even after controlling for initial EF skill
• There is stability in children's relative vocabulary size and executive functioning performance over time in early childhood

     

Young children's self‐benefiting lies and their relation to executive functioning and theory of mind

It is well established that children lie in different social contexts for various purposes from the age of 2 years. Surprisingly, little is known about whether very young children will spontaneously lie for personal gain, how self‐benefiting lies emerge, and what cognitive factors affect the emergence of self‐benefiting lies. To bridge this gap in the literature, we situated children between 2 and 4 years of age in a zero‐sum game where children must lie to their opponent if they wanted to win a desirable reward. We found that the majority of young children did not lie even when they experienced personal losses repeatedly. However, some children spontaneously lied during the game; as the game progressed, more children lied. Further, we found that children's theory of mind understanding and executive functioning in terms of a combination of inhibitory control and cognitive flexibility had significant positive and unique correlations with how frequently children lied for personal gain. The present results taken together with the existing findings regarding children's lies for self‐protection and politeness purposes suggest that the act of lying begins early in life. Further, its emergence and development are influenced by children's specific cognitive abilities in the domains of theory of mind understanding and executive functioning.

Highlights

• The study investigated whether very young children will spontaneously lie for personal gain.
• This study used a zero‐sum game to elicit children's self‐benefiting lies. Results showed the majority of young children did not lie, and it is related to children's theory of mind understanding and executive functioning.
• The act of lying begins early in life, and its emergence and development are influenced by children's specific cognitive abilities in the domains of theory of mind understanding and executive functioning.

     

The contribution of logical reasoning to the learning of mathematics in primary school

It has often been claimed that children's mathematical understanding is based on their ability to reason logically, but there is no good evidence for this causal link. We tested the causal hypothesis about logic and mathematical development in two related studies. In a longitudinal study, we showed that (a) 6‐year‐old children's logical abilities and their working memory predict mathematical achievement 16 months later; and (b) logical scores continued to predict mathematical levels after controls for working memory, whereas working memory scores failed to predict the same measure after controls for differences in logical ability. In our second study, we trained a group of children in logical reasoning and found that they made more progress in mathematics than a control group who were not given this training. These studies establish a causal link between logical reasoning and mathematical learning. Much of children's mathematical knowledge is based on their understanding of its underlying logic.     

Holding in Mind Conflicting Information: Pretending,Working Memory,and Executive Control

Preschoolers' recall of the true and pretend identities of an object in pretense was examined along with a battery of executive functioning and working memory tasks. We expected that children would retain separate identities, as well as a link between them, after observing episodes of pretense, and that memory for pretense would be related to executive functioning and working memory. Children (aged 37–59 months) recalled the true identity of an object better than its pretend identity. Children's recall of at least one identity was correlated with executive functioning and “dual” working memory tasks, independent of age and verbal ability. Memory for both identities was only correlated with executive functioning. The findings are generally supportive of the claim that children form separate representations of the true and pretend identities of objects. The results extend findings of well-established relations between false belief tasks and executive functioning and working memory.     

When Children's Knowledge of Memory Improves Children's Performance in Memory

One of the strongest hypotheses in the field of metacognition research involves the positive effect of metamemory on memory performance. However, owing to the lack of appropriate instruments to appraise knowledge of memory, few studies have examined this effect among children. This study was conducted to create and validate an instrument to assess children's metamemory knowledge and link this knowledge with their memory performance and strategy use. A sample of 166 children was given a new three‐factor metamemory interview, and its psychometric properties were investigated. Regression analyses were carried out to investigate the link between metamemory and memory performance in a subgroup of 128 children from the validation study. Results confirmed the scale's good psychometric properties and revealed its ability to predict children's memory performance. However, none of the scale's factors could predict children's use of memory strategies. Implications for the study of children's metamemory development are discussed.

Intervention response among preschoolers with ADHD: The role of emotion understanding

Emotion recognition/understanding (ERU), which is the ability to correctly identify emotional states in others as well as one's self, plays a key role in children's social-emotional development and is often targeted in early intervention programs. Yet the extent to which young children's ERU predicts their intervention response remains unclear. The current study examined the extent to which initial levels of ERU and changes in ERU predicted intervention response to a multimodal early intervention program (Summer Treatment Program for Pre-Kindergarteners; STP-PreK). Participants included 230 young children (M_age = 4.90, 80.0% male) with attention-deficit/hyperactivity disorder (ADHD) who participated in the 8-week STP-PreK. Children's ERU was measured via a standardized behavioral task. Similarly, standardized measures of academic achievement (Woodcock-Johnson-IV), executive functioning (Head-Toes-Knees-Shoulders-Task), and social-emotional functioning (Challenging Situation Task) were obtained pre- and post-intervention. Parents and teachers also reported on children's behavioral functioning pre- and post-intervention. Children with better initial ERU made greater improvements in academic, executive functioning (EF), and social-emotional domains, along with decreases in inattention symptom severity. However, pre-intervention levels of ERU were not associated with improvements in parent/teacher report of hyperactivity, oppositional defiant disorder, and overall behavioral impairment. Lastly, changes in ERU only predicted improvement in EF, but not any other school readiness outcomes. We provide preliminary evidence that initial levels of ERU predict intervention response across school readiness domains in a sample of preschoolers with ADHD.     

Relationship of cognitive strategy use to prospective memory performance in a diverse sample of nondemented older adults with varying degrees of cognitive complaints and impairment

Although older adults typically have better performance on prospective memory (PM) tasks carried out in naturalistic settings, a paucity of research directly assesses older adults’ use of compensatory strategies on such tasks. The current study investigates external memory strategy use during performance of a clinical PM test that features both short-term (in laboratory) and long-term (out of laboratory) subtasks (i.e., the Royal Prince Alfred Prospective Memory Test – RPA-ProMem. Nondemented, community-dwelling older adults (n = 214; mean age = 80.5; 68.2% female; 39.7% non-white) with mild cognitive impairment, subjective cognitive decline, and healthy controls completed the RPA-ProMem while external strategy use was permitted and recorded. Overall, participants utilized external strategies 41% of the time on the RPA-ProMem. Increased utilization of external memory strategies was significantly associated with better PM performance. Additionally, better performance on executive functioning tasks was associated with increased use of external memory strategies. Results are discussed in relation to how memory strategy use can be enhanced to improve everyday memory ability in older adults at risk for dementia.     

Relation of infant motor development with nonverbal intelligence,language comprehension and neuropsychological functioning in childhood: a population‐based study

Within a population‐based study of 3356 children, we investigated whether infant neuromotor development was associated with cognition in early childhood. Neuromotor development was examined with an adapted version of Touwen's Neurodevelopmental Examination between 9 and 20 weeks. Parents rated their children's executive functioning at 4 years. At age 6 years, children performed intelligence and language comprehension tests, using Dutch test batteries. At age 6–9 years, neuropsychological functioning was assessed in 486 children using the validated NEPSY‐II–NL test battery. We showed that less optimal neurodevelopment in infancy may predict poor mental rotation, immediate memory, shifting, and planning; but not nonverbal intelligence or language comprehension.     

How knowing and doing inform an autobiography: relations among preschoolers' theory of mind,narrative, and event memory skills

Research on the development of autobiographical memory in children has revealed the importance of two seemingly separate but related factors: Theory of mind, or the ability to know what another can and cannot know, and narrative skill, or the ability to tell a coherently structured story. The present research study with 22 preschoolers examined the extent to which each factor predicts two separate components of autobiographical memory ability: (1) the content of memory and (2) the structure of the memory narrative. As hypothesized, we found that theory of mind skills predicted the ‘how’ or structure of the children's fictional story narratives, whereas narrative skills predicted the ‘how much’ or content of the children's memory. Implications for the development of autobiographical memory are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Prospective Memory Impairment in Mild Cognitive Impairment: An Analytical Review

Mild cognitive impairment (MCI) is a heterogeneous condition characterized by the presence in an otherwise healthy elderly individual of cognitive deficits involving specific domains in the absence of significant functional impairments. Reports indicate that prospective memory (PM), that is, the ability to remember to execute delayed intentions, is impaired in individuals with MCI. The present review discusses the current debate in the literature on PM functioning in MCI by focusing on the relationship between prospective retrieval and retrospective memory functioning. Analysis of the reported evidence revealed that both the prospective component and the retrospective component of PM can be impaired in MCI. Declarative memory dysfunction may account for the retrospective memory impairment, while either reduced executive abilities or a deficit of reflexive mechanisms could explain the prospective component impairment.     

Correspondence in parents' and children's concepts of god: Investigating the role of parental values,religious practices and executive functioning

This study examined the extent to which children's concepts of God correspond with their parents' concepts of God. It also examined how parent-context factors and children's executive functioning relate to parent–child conceptual similarity. Parent–child dyads from varied religious and racial backgrounds participated. Dyads had the greatest conceptual similarity concerning God's mind-dependent functions. Though correspondence between parents and children was lowest concerning God's body-dependent functions, dyads were more similar about those functions when parents engaged in more frequent religious practices with their child and thought God was important. Children's concepts of God were unrelated to religious practices, and parent–child conceptual similarity was unrelated to children's age and executive functioning. Simply put, variation among parents' anthropomorphic concepts of God drove variation in parent–child conceptual similarity. Overall, these findings suggest that embodied concepts of God may be most sensitive to cultural input and that socialization practices provide greater insight into parents' anthropomorphic concepts.     

Neuropsychological Functioning in Children with Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) has been associated with deficits in the areas of verbal memory and learning, executive functioning, working memory, and attention in adults. Findings have been less consistent in the few studies examining neuropsychological functioning in childhood PTSD, which are often limited by comparing children with PTSD to children without trauma histories, making it unclear whether observed neuropsychological deficits are related to trauma exposure or to PTSD symptomatology. In an ethnically diverse sample of 62 children who witnessed intimate partner violence (n = 27 PTSD+ and 35 PTSD?), children with PTSD exhibited slower and less effective learning, heightened sensitivity to interference, and impaired effect of rehearsal on memory acquisition on the California Verbal Learning Test – Children's Version, a word list learning task. Both groups performed in the below average range on measures of executive functioning, attention, and intellectual ability.
