Promoting Honesty: The Influence of Stories on Children's Lie‐Telling Behaviours and Moral Understanding

Moral stories are a means of communicating the consequences of our actions and emphasizing virtuous behaviour, such as honesty. However, the effect of these stories on children's lie‐telling has yet to be thoroughly explored. The current study investigated the influence of moral stories on children's willingness to lie for another individual. Children were read one of three stories prior to being questioned about an accidental wrongdoing: (1) a positive story, which emphasized the benefits of being honest; (2) a negative story, which outlined the potential costs of lying; and (3) a neutral story, which was unrelated to truth‐telling or lie‐telling. Initially, most children withheld information about the event. Older children were better able to maintain their lies throughout the interview. However, when asked direct questions, children in the positive story condition were more likely to tell the truth than those in the negative and neutral conditions. No significant differences were found between the negative and neutral story conditions. The present study also investigated the relationship between children's conceptual understanding and behaviour. The findings revealed that children's knowledge of truths and lies increased with age. Children who lied had significantly higher conceptual scores than those who did not lie. Furthermore, the type of story children were read had a significant impact on their evaluations of true and false statements. Copyright © 2015 John Wiley & Sons, Ltd.     

Learning through observing: Effects of modeling truth‐ and lie‐telling on children’s honesty

The current study examined the influence of observing another's lie‐ or truth‐telling – and its consequences – on children's own honesty about a transgression. Children (N = 224, 5–8 years of age) observed an experimenter (E) tell the truth or lie about a minor transgression in one of five conditions: (a) Truth‐Positive Outcome – E told the truth with a positive outcome; (b) Truth‐Negative Outcome – E told the truth with a negative outcome; (c) Lie‐Positive Outcome – E lied with a positive outcome; (d) Lie‐Negative Outcome – E lied with a negative outcome; (e) Control – E did not tell a lie or tell the truth. Later, to examine children's truth‐ or lie‐telling behavior, children participated in a temptation resistance paradigm where they were told not to peek at a trivia question answer. They either peeked or not, and subsequently lied or told the truth about that behavior. Additionally, children were asked to give moral evaluations of different truth‐ and lie‐telling vignettes. Overall, 85% of children lied. Children were less likely to lie about their own transgression in the TRP when they had previously witnessed the experimenter tell the truth with a positive outcome or tell a lie with a negative outcome.     

Theory of Mind and Executive Functions in Young Bilingual Children

Few studies have explored the relationship between theory of mind (ToM), executive function (EF), and bilingualism at the same time. In this study 14 young bilingual children were compared with monolingual children on a test battery composed of 5 ToM tests, 5 EF tests, and 1 test of general language ability. The result showed that despite significantly lower verbal ability, the bilingual children outperformed the monolingual ones on tests of EF. There were no differences in ToM performance. The authors argue that there is a strong relationship between bilingualism and EF, but, contrary to results from earlier studies, they could not find any relationship between bilingualism and ToM. EF did not predict ToM performance. Lack of a significant relationship could be due to the children's young age and consequently their low scores on the ToM tasks.     

The Relationship of Suicidal Ideation to Objective and Subjective Executive Functioning

Prior research on executive ability and suicidal ideation (SI) has frequently failed to account for either symptom or performance validity. Similarly, studies have not adequately examined both objective performance on executive tests and subjective report of executive deficits in relationship to SI. The purpose of this study was to address these gaps in research by accounting for performance validity, symptom validity, and considering self-reported executive complaints with objective performance. We hypothesized that (a) increases in self-reported SI on the Personality Assessment Inventory (PAI; Morey, 1991 Morey, L. C. (1991). Personality Assessment Inventory: Professional manual. Tampa, FL: Psychological Assessment Resources. [Google Scholar]) Suicidal Ideation subscale would be related to poorer performance on objective and subjective tests of executive function and (b) level of self-reported depressive symptoms would moderate the relationship between SI and measures of executive function, such that individuals with higher levels of both depressive symptoms and executive dysfunction would be more likely to experience higher levels of SI. No measure of executive function was related to SI when accounting for demographic variables and depressive symptoms. Wisconsin Card Sort Test categories completed was the only measure of executive function to interact significantly with depressive symptoms to predict SI (β = .43). Of particular note, self-reported executive dysfunction was highly correlated with Beck Depression Inventory?II ( Beck, Steer, &; Brown, 1996 Beck, A. T., Steer, R. A., &; Brown, G. K. (1996). Beck Depression Inventory (2nd ed.). San Antonio, TX: The Psychological Corporation. [Google Scholar]) scores (r = .78). Clinical implications and future directions for research are discussed.     

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.

Aging, Executive Functioning, and Social Control

ABSTRACT— Aging is associated with atrophy of the frontal lobes of the brain, which are the seat of executive functions. Because successful social functioning often requires executive control, aging can lead to unintended social changes via deficits in executive control. In this article I review evidence that, due to losses in executive control, aging leads to increased prejudice and social inappropriateness and, under certain circumstances, increased depression and problem gambling. I then discuss theory and research suggesting possible interventions that might ameliorate unwanted social changes brought about by executive decline.     

The Effect of Maltreatment Type on Adolescent Executive Functioning and Inner Speech

There are indications that different types of maltreatment can lead to different cognitive and behavioural outcomes. This study investigated whether maltreatment type was related to executive functioning (EF) abilities and the use of inner speech. Forty maltreated adolescents and a comparison group of 40 non‐maltreated typically developing adolescents completed a battery of tasks designed to assess both their EF abilities and their vulnerability to disruptions to inner speech. They also completed an IQ test. Multivariate analysis of covariance (MANCOVA) and ANCOVA analyses were carried out to examine potential effects of maltreatment type (abuse alone; neglect alone; abuse/neglect combined and no maltreatment) on EF and use of inner speech. Maltreatment type was related to EF abilities. In particular, abuse only and abuse/neglect combined had a greater negative impact on EF than neglect only. However, the neglect alone group was more vulnerable to disruptions to inner speech than the other two maltreatment groups, suggesting that they may be more reliant on the use of inner speech. These findings provide new insights into the differential impact of maltreatment type on EF and the use of inner speech in adolescence and could be used to improve the educational outcomes of these vulnerable young people.

Executive and Attention Functioning Among Children in the PANDAS Subgroup

Evidence from past studies indicates that adults and children with Obsessive-Compulsive Disorder (OCD) and Tourette syndrome (TS) experience subtle neuropsychological deficits. Less is known about neuropsychological functioning of children and adolescents with a symptom course consistent with the PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection) subgroup of OCD and tics. To provide such information, we administered three tests of attention control and two of executive function to 67 children and adolescents (ages 5–16) diagnosed with OCD and/or tics and a symptom course consistent with the PANDAS subgroup and 98 healthy volunteers (HV) matched by age, sex, and IQ. In a paired comparison of the two groups, the PANDAS subjects were less accurate than HV in a test of response suppression. Further, in a two-step linear regression analysis of the PANDAS group in which clinical variables were added stepwise into the model and in the second step matching variables (age, sex, and IQ) were added, IQ emerged as a predictor of performance on this task. In the same analysis, ADHD diagnosis and age emerged as predictors of response time in a continuous performance task. Subdividing the PANDAS group by primary psychiatric diagnosis revealed that subjects with TS or OCD with tics exhibited a longer response time compared to controls than subjects with OCD only, replicating previous findings within TS and OCD. This study demonstrates that children with PANDAS exhibit neuropsychological profiles similar to those of their primary psychiatric diagnosis.     

The Mediating Role of Executive Functioning in the Relation Between Difficult Temperament and Physical Aggression

The present investigation tested the hypothesis that executive functioning (EF) would mediate the relation between difficult temperament (DT) and aggressive behavior. This model was tested in 310 adult men and women. DT was measured using the Dimensions of Temperament Scale—Revised, EF was measured using 7 well-established neuropsychological tests, and aggression was assessed using the Buss–Perry Aggression Questionnaire. EF successfully mediated the DT–aggression relation for men, however, the model did not hold for women. Results are discussed with regard to how they influence current models of aggressive behavior as well as their implications for future violence prevention efforts.

Executive Functioning in Children and Adolescents with Major Depressive Disorder

The present investigation examined neurocognitive functioning, focusing on executive functioning (EF), in 39 children and adolescents with Major Depressive Disorder (MDD) and 24 healthy control subjects all ages 8 to 17 years. The Wechsler Intelligence Scale for Children-Third Edition along with several measures of executive functioning including the Wisconsin Card Sorting Task, Trail Making Test, Controlled Oral Word Association Test, and the Stroop Color Word Test were administered. The neurocognitive profiles for the group of depressed children and adolescents were grossly intact as most scores on intellectual and EF measures fell within the average range and did not differ from the comparison group. Mental processing speed was decreased in the MDD versus normal control group and 27% of the depressed group performed below average on the Trail Making Test. This investigation provided a good base from which to compare future literature on EF in outpatients with early-onset MDD.

Sustained Attention and Executive Functioning Performance in Attention-Deficit/Hyperactivity Disorder

The aim of this study was to further refine the cognitive phenotype of attention-deficit/hyperactivity disorder (ADHD), with respect to the ability to sustain attention and executive functioning. Participants were 34 boys with ADHD (combined type) and 28 normal controls. The groups were closely matched for age and IQ. All participants were 12 years of age. Both groups performed a computerized sustained attention task and a response interference task. Measures related to speed, accuracy, and time on task were collected. We found that children with ADHD performed slower, less accurately, more impulsively, and with less stability than controls. Both groups produced more errors with increasing time on task, reflecting reduced vigilance. Importantly, no interaction with time on task was found. The overall pattern of results suggests that measures related to accuracy are more informative than measures related to speed of responding in refining the cognitive phenotype of ADHD.

Executive Function in Young Children and Chimpanzees (Pan troglodytes): Evidence From a Nonverbal Dimensional Change Card Sort Task

In this article the authors compared chimpanzees’ executive function with that of children. They developed a nonverbal dimensional change card sorting task, which indexed the development of executive function. Three pairs of mother and offspring chimpanzees and 30 typically developed 5-year-old children were presented with 2 target stimuli and a test stimulus comprising 2 dimensions (size and shape) on a display; they were required to sort the test stimulus according to 1 dimension (e.g., shape). After 5 consecutive correct trials, the participants had to sort the test stimulus according to the other dimension (e.g., size). The results showed that the chimpanzees often failed to sort the test stimuli according to the first and reversed dimensions. On the other hand, the children were correctly able to use both dimensions. These results indicate that chimpanzees may have less developed executive skills than children.     

Word Mapping and Executive Functioning in Young Monolingual and Bilingual Children

The effect of bilingualism on the cognitive skills of young children was investigated by comparing performance of 162 children who belonged to one of two age groups (approximately 3- and 4.5-year-olds) and one of three language groups on a series of tasks examining executive control and word mapping. The children were monolingual English speakers, monolingual French speakers, or bilinguals who spoke English and one of a large number of other languages. Monolinguals obtained higher scores than bilinguals on a receptive vocabulary test and were more likely to demonstrate the mutual exclusivity constraint, especially at the younger ages. However, bilinguals obtained higher scores than both groups of monolinguals on three tests of executive functioning: Luria's tapping task measuring response inhibition, the opposite worlds task requiring children to assign incongruent labels to a sequence of animal pictures, and reverse categorization in which children needed to reclassify a set of objects into incongruent categories after an initial classification. There were no differences between the groups in the attentional networks flanker task requiring executive control to ignore a misleading cue. This evidence for a bilingual advantage in aspects of executive functioning at an earlier age than previously reported is discussed in terms of the possibility that bilingual language production may not be the only source of these developmental effects.
