“Scatter Analysis” Techniques Applied to Anxiety Neurotics from a Restricted Culturo-Educational Environment

Hearing-impaired children were individually administered a task in which possession of accumulating candy rewards was made contingent upon the child's decision to stop any further accumulation of the candy. Hearing-impaired children, who under instruction periodically made American Sign Language (ASL) statements about the goodness of the reward, waited significantly longer before terminating the waiting period than did hearing-impaired children instructed to sign statements about the act of waiting and somewhat longer than did hearing-impaired children instructed to sign a neutral statement. Since the pattern of delay was unlike that reported in earlier investigations when nonhandicapped children verbalized similar statements and since variation in mode of communication did not influence delay in nonhandicapped children in the present investigation, the results were interpreted in terms of differences in cognitive controlling mechanisms between nonhandicapped and hearing-impaired children.     

Age and overt verbalization in delay-maintenance behavior in children

The influence of overt self-verbalization on the maintenance of self-imposed delay of gratification was investigated in a task in which the child's possession of accumulating candy rewards was made contingent upon the child stopping further accumulation. Preschool girls who verbalized about the goodness of waiting and preschool girls who uttered an irrelevant verbalization waited longer before terminating their delay than did preschool girls who verbalized about the delayed reward or were silent. Second- and third-grade girls who verbalized about the goodness of waiting or who were silent waited longer than girls of the same age who verbalized about the delayed reward.     

Evaluative verbalization and delay maintenance behavior in children

An experiment is presented which examined the influence of verbalizations on children's tendencies to postpone immediate gratification in terms of increased delayed reward. Children's verbalizations were varied in terms of their evaluative valence and whether they focused upon the reward itself or the delay task. During a delay task children in experimental groups periodically verbalized evaluative statements that were either positive (I like …) or negative (I don't like …) and which focused upon either the reward itself (… the tokens) or the delay behavior (… to wait). Children who focused on reward, under conditions of either positive or negative evaluation, postponed immediate gratification less than control subjects who made no verbalization. Children who evaluated delay behavior positively postponed immediate gratification longer than silent subjects, though children who negatively evaluated delay behavior did not differ from subjects who did not verbalize. The results are interpreted in terms of the influence of evaluative valence and focus as parameters of plans for delay behavior.     

How do generic statements impact performance? Evidence for entity beliefs

Generic statements about the abilities of children's social groups (e.g. ‘Girls/Boys are good at this game’) negatively impact children's performance – even if the statements are favorable towards children's own social groups. We explored the mechanism by which generic language impairs children's performance. Across three studies, our findings suggest that generic statements influence children's performance by creating an entity belief (i.e. a belief that a fixed ability determines performance). Children who were exposed to a generic statement about their social group's ability performed worse than children in control conditions. This effect hurt children's performance even when the person who made the generic statement was no longer present and a new person not privy to the statement replaced them. However, when children heard a generic statement paired with an effort explanation (i.e. ‘Girls/Boys are good at this game because they try really hard when they draw’) they performed better than children who heard the generic statement with no explanation (i.e. just ‘Girls/Boys are good at this game’) and children who heard the generic statement paired with a trait explanation (i.e. ‘Girls/Boys are good at this game because they are smart and really good at drawing’). This work uncovers when and how generic statements that refer to the ability of one's social group hinder performance, informing the development of practices to improve student motivation and learning.     

Fixed-interval performance and self-control in children.

Operant responses of 16 children (mean age 6 years and 1 month) were reinforced according to different fixed-interval schedules (with interreinforcer intervals of 20, 30, or 40 s) in which the reinforcers were either 20-s or 40-s presentations of a cartoon. In another procedure, they received training on a self-control paradigm in which both reinforcer delay (0.5 s or 40 s) and reinforcer duration (20 s or 40 s of cartoons) varied, and subjects were offered a choice between various combinations of delay and duration. Individual differences in behavior under the self-control procedure were precisely mirrored by individual differences under the fixed-interval schedule. Children who chose the smaller immediate reinforcer on the self-control procedure (impulsive) produced short postreinforcement pauses and high response rates in the fixed-interval conditions, and both measures changed little with changes in fixed-interval value. Conversely, children who chose the larger delayed reinforcer in the self-control condition (the self-controlled subjects) exhibited lower response rates and long postreinforcement pauses, which changed systematically with changes in the interval, in their fixed-interval performances.     

四种注意情境下幼儿自我延迟满足的实验研究

将120名中等自控能力的3～5岁幼儿随机分配到四种注意情境下:两种奖励物同时呈现、只呈现即时奖励物、只呈现延迟奖励物、两种奖励物都不呈现,以探索幼儿自我延迟满足的注意机制及发展特点。结果发现:(1)幼儿自我延迟满足在两种奖励物都不呈现情境下平均延迟时间最长,在呈现奖励物的三种情境下平均延迟时间较短,表现出跨年龄稳定性;(2)3～5岁幼儿自我延迟满足发展存在显著年龄差异,表现出随年龄增长而提高的趋势。     

A computerized test of self-control predicts classroom behavior

We assessed choices on a computerized test of self-control (CTSC) for a group of children with features of attention deficit hyperactivity disorder (ADHD) and a group of controls. Thirty boys participated in the study. Fifteen of the children had been rated by their parents as hyperactive and inattentive, and 15 were age- and gender-matched controls in the same classroom. The children were observed in the classroom for three consecutive mornings, and data were collected on their activity levels and attention. The CTSC consisted of two tasks. In the delay condition, children chose to receive three rewards after a delay of 60 s or one reward immediately. In the task-difficulty condition, the children chose to complete a difficult math problem and receive three rewards or complete an easier problem for one reward. The children with ADHD features made more impulsive choices than their peers during both conditions, and these choices correlated with measures of their activity and attention in the classroom.     

The Effect of Symbolic Distancing on Delay Tolerance across the Preschool Period

ABSTRACT

We aimed to longitudinally examine how symbolic distancing affects preschool children’s delay tolerance in a delay choice task. We presented children with choices between a smaller immediate reward and a larger delayed reward in conditions with either symbolic stimuli or edible rewards. Overall, symbolic distancing modulated children’s delay tolerance. In particular, whereas in the first phase (T1: 3- and 4-year-olds) children presented with edible rewards chose the larger option more often than children presented with symbolic stimuli, in the second phase (T2: 5- and 6-year-olds), there was no significant difference between children presented with symbolic stimuli and those presented with edible rewards. These results are discussed by examining how children’s delay tolerance changes during the development and comparing children to adult humans in a similar task.     

Strategic attention deployment for delay of gratification in working and waiting situations

Two studies examined whether the detrimental effects of attention to rewards on delay of gratification in waiting situations holds-or reverses-in working situations. In Study 1, preschoolers waited or worked for desired delayed rewards. Delay times increased when children worked in the presence of rewards but, as predicted, this increase was due to the distraction provided by the work itself. not because attention to rewards motivated children to sustain work. Analysis of spontaneous attention deployment showed that attending to rewards reduces delay time regardless of the working or waiting nature of the task. Fixing attention on rewards was a particularly detrimental strategy regardless of the type of task. Study 2 showed that when the work is not engaging, however, attention to rewards can motivate instrumental work and facilitate delay of gratification as long as attention deployment does not become fixed on the rewards.     

Possession is not always the law: With age, preschoolers increasingly use verbal information to identify who owns what

Children can identify owners either by seeing a person in possession of an object (a visual cue) and inferring that they are the owner or by hearing testimony about a claim of ownership (a verbal cue). A total of 391 children between 2.5 and 6years of age were tested in three experiments assessing how children identify owners when these two cues are in conflict. Children were presented with stories using two dolls and a toy. One doll possessed the toy, and children were told that the toy was either the possessor's or the nonpossessor's. Two forms of ownership statement were used: a third-person statement, "That is Billy's ball", and a first-person statement by one of the dolls, "That is my ball". The results show that by 4years of age, children prioritize the verbal statements as a more reliable cue to ownership than physical possession. Younger children did not prioritize possession over the verbal cue to ownership but rather gave mixed responses. These results are discussed in terms of children's social experience outside of the home and their acceptance of testimony in other domains.     

The efficacy of free‐recall,cognitive load,and closed‐ended questions when children are asked to falsely testify about a crime

The current study evaluated the benefits of free‐recall, cognitive load, and closed‐ended questions on children's (ages 6 to 11; N = 147) true and false eyewitness disclosures. Children witnessed an experimenter find a stranger's wallet and were then asked to make a false denial, false accusation, true denial, or true accusation regarding an alleged theft. Overall, the free‐recall question resulted in longer, more forthcoming and more detailed disclosures from older children and those who made a truthful accusation; however, children under the age of 9 and lie‐tellers mostly relied on the closed‐ended questions to discuss the theft. Although the cognitive load questions resulted in newly recalled information, there were no significant narrative differences between true and false statements on these questions. These findings suggest that forensic professionals should consider a child's developmental level, statement veracity, and disclosure‐type (denial vs. accusation) when examining the efficacy of these commonly used questioning strategies.     

The rich get richer: Students’ discounting of hypothetical delayed rewards and real effortful extra credit

The present research compared choices among students with higher or lower grades for rewards that were devalued by imposing a delay to their receipt (Study 1) or by requiring more work for a larger reward (Study 2). In Study 1, students chose between hypothetical and noncontingent smaller immediate or larger delayed monetary rewards. In Study 2, students chose from among different amounts of real, response-contingent academic rewards (extra credit) that required different amounts of work. The results of both studies were similar: The highest scoring students discounted the value of the delayed money less than did their lower scoring counterparts, and the highest scoring students also chose to do and actually did more extra-credit work than lower scoring students did. Differences in the discounting of devalued rewards might represent a fundamental difference between the highest and lower scoring students.     

Trust matters: Seeing how an adult treats another person influences preschoolers' willingness to delay gratification

Holding out for a delayed reward in the face of temptation is notoriously difficult, and the ability to do so in childhood predicts diverse indices of life success. Prominent explanations focus on the importance of cognitive control. However, delaying gratification may also require trust in people delivering future rewards as promised. Only limited experimental work has tested this idea, and such studies with children were focused on general reward expectations, so evidence was ambiguous as to whether social trust played a role. The present study provides the first targeted test of a role for social trust in children's willingness to delay gratification. Children observed an adult behave in either a trustworthy or untrustworthy manner toward another adult, then were tested in the classic delay of gratification task by that adult. Children were less likely to wait the full delay period, and waited less time overall, for a reward promised by an untrustworthy adult, relative to children tested by a trustworthy adult. These findings demonstrate that manipulations of social trust influence delaying gratification, and highlight intriguing alternative reasons to test for individual differences in delaying gratification and associated life outcomes.     

Ways of reacting to communication failure in relation to the development of the child's understanding about verbal communication

Tested the hypothesis that explicit identification of message ambiguity as a reason for failure in referential communication could help young children to gain understanding about the need for unique reference in communicative acts, in both experimental and natural settings. In the experiment each of 47 children aged 5-2 to 6-5 selected and then described clothes for a doll so that the experimenter could choose matching items. Ambiguous instructions from the children were consistently responded to with one of three reactions by the experimenter: (1) she guessed an item, (2) she asked ‘Which one?’ waited and chose or (3) she made explicit why she could not make a unique choice on the basis of the child's message. Both before and after this manipulation children were assessed for their understanding that messages can be ambiguous and can cause communication failure. Children accorded the third treatment improved most both in understanding and in reducing the ambiguity of their messages. A similar assessment of understanding was made of 36 6-year-old children of whom recordings of interaction in the home had been made over several previous years. Children whose mothers had made explicit their lack of understanding of their child's utterances were more advanced than those whose mothers had not.     

DISCOUNTING OF DELAYED REWARDS:

Abstract— In this study, children, young adults, and older adults chose between immediate and delayed hypothetical monetary rewards The amount of the delayed reward was held constant while its delay was varied All three age groups showed delay discounting, that is, the amount of an immediate reward judged to be of equal value to the delayed reward decreased as a function of delay The rate of discounting was highest for children and lowest for older adults, predicting a life-span developmental trend toward increased selfcontrol Discounting of delayed rewards by all three age groups was well described by a single function with agesensitive parameters (all R²s>94) Thus, even though there are quantitative age differences in delay discounting, the existence of an age-invanant form of discount function suggests that the process of choosing between rewards of different amounts and delays is qualitatively similar across the life span     

Hyperactivity and frustration: The influence of control over and size of rewards in delaying gratification

This study examined the differential effects of frustration on normal children and those diagnosed as having Attention Deficit Disorder with Hyperactivity. Each group consisted of 16 boys between the ages of 6 and 8 years who were prematched for age, grade, and classroom placement. All children completed a series of arithmetic problems in order to earn toy rewards. Using a variant of Mischel's (1974) delay-of-gratification paradigm, children were presented with two choice-of-delay conditions in a randomly assigned, counterbalanced sequence: a free-choice conflict situation involving a long-passive or short-active reward delay, and a short-active delay. Results showed that a significantly greater proportion of hyperactive children chose to complete problems for an immediate reward compared to their normal control counterparts (p less than .01). Group differences were no longer apparent in the short-active delay trial. The results are discussed in terms of frustration tolerance and contributing factors such as cognitive-attentional style. Implications for treatment and future directions are delineated.     

Examining children's ability to delay reward: Is the delay discounting task a suitable measure?

Discounting the value of delayed rewards has primarily been measured in children with the delay of gratification task and in adolescents and adults with the delay discounting task. In the present study, we assessed the suitability of the delay discounting task as a measure of temporal discounting in children. A sample of 7- to 9-year-olds (N = 98) completed a delay discounting task, a delay of gratification task, a sensation seeking measure, and IQ measures. In addition, teacher-based assessments of attention-deficit/hyperactivity disorder traits were measured. The results indicated that the majority of children produced meaningful data on the discounting task and discounted rewards hyperbolically. Children with an elevated risk of attention-deficit/hyperactivity disorder showed a trend towards discounting future rewards on the delay discounting task more steeply than did those at low risk. However, delay discounting was unrelated to either delay of gratification or sensation seeking. We interpret these results as providing some support for the use of delay discounting as a measure of intertemporal choice in children, although the results also suggest that delay discounting and delay of gratification tasks may tap different processes in this population.     

Adults' ability to detect children's lying

Adults are poor deception detectors when examining lies told by adults, on average. However, there are some adults who are better at detecting lies than others. Children learn to lie at a very young age, a behavior that is socialized by parents. Yet, less is known about the ability to detect children's lies, particularly with regard to individual differences in the ability to detect this deception. The current study explored adult raters' ability to discern honesty in children who lied or told the truth about committing a misdeed. Results showed that adults are no better at detecting children's lies than they are with adult lies. In particular, adults were very poor at identifying children's honest statements. However, individual differences did emerge, suggesting that the ability to detect lying in children might be facilitated by relevant experience working with children. Implications for legal and mental health contexts are discussed.
