Can rapport building strategies,age, and question type influence preschoolers’ disclosures of adult wrongdoing?

In the present experiment, we examined preschoolers’ disclosures of a secret as a function of rapport building strategies used in Scandinavian field settings (verbal rapport building vs. prop rapport building), age in months (33–75 months) and question type (open-ended free recall invitation vs. suggestive questions). Fifty-three preschoolers (M = 60.5 months old, SD = 11.4) witnessed a researcher break a toy and were asked to keep the toy breakage a secret. The children were thereafter interviewed about the incident. Overall, 18.9% of the children disclosed the secret after an open-ended free recall invitation. The disclosure rate rose to 83% after the final phase of the interviews when questions containing suggestive details were asked of the children. Notably, we did not observe any significant effects as a function of manipulating rapport building strategy. A linear regression model showed that child age (in months) significantly predicted the amount of reported details, with younger preschoolers reporting fewer details compared to older preschoolers. Age also predicted the amount of correct details, but not the amount of incorrect details. No age differences were found with regard to children’s disclosure tendencies or proportion of central details about the secret. Methodological limitations and practical implications will be addressed.     

Event frequency and children's suggestibility: a study of cued recall responses

Research examining the effect of repeated experience on children's suggestibility for particular kinds of information has produced differing results. In one study, responses to recognition questions revealed heightened suggestibility for variable details in children who repeatedly experienced an event compared to children who experienced an event once. In other studies, no such effect was found with cued recall. In this study, 4–5‐year old children engaged in one or four play sessions. Children were later given a biasing interview wherein half of the details were incorrectly represented. Children were then given a final memory test using free and cued recall prompts that was preceded by one of three instruction types: no special instructions, moderate instructions, or opposition instructions. Children in the repeated‐event condition were more suggestible than those in the single‐event condition, regardless of instructions. No significant differences in suggestibility were found across instructions conditions. Copyright © 2004 John Wiley & Sons, Ltd.     

Teaching children with autism to ask questions about hidden objects

We taught 2 4‐year‐old children with autism to ask questions of an adult who held a closed box with a toy inside. The treatment package (modeling, prompting, and reinforcement) was evaluated with a multiple baseline design across the three question forms during training, generalization, and follow‐up evaluations. The first question form (“What's that?”) produced the name of the hidden item. The second form (“Can I see it?”) produced sight of it, and the third form (“Can I have it?”) produced the item itself. Both children learned to ask questions about hidden objects.     

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.     

Intoxicated eyewitnesses: The effect of a fully balanced placebo design on event memory and metacognitive control

Few studies have examined the impact of alcohol on metacognition for witnessed events. We used a 2 × 2 balanced placebo design, where mock witnesses expected and drank alcohol, did not expect but drank alcohol, did not expect nor drank alcohol, or expected but did not drink alcohol. Participants watched a mock crime in a bar‐lab, followed by free recall and a cued‐recall test with or without the option to reply “don't know” (DK). Intoxicated mock witnesses' free recall was less complete but not less accurate. During cued‐recall, alcohol led to lower accuracy, and reverse placebo participants gave more erroneous and fewer correct responses. Permitting and clarifying DK responses was associated with fewer errors and more correct responses for sober individuals; and intoxicated witnesses were less likely to opt out of erroneous responding to unanswerable questions. Our findings highlight the practical and theoretical importance of examining pharmacological effects of alcohol and expectancies in real‐life settings.     

Effects of testing on subsequent re‐encoding and long‐term forgetting of action‐relevant materials: On the influence of recall type

Testing one's memory of previously studied information reduces the rate of forgetting, compared to restudy. However, little is known about how this direct testing effect applies to action phrases (e.g., “wash the car”) – a learning material relevant to everyday memory. As action phrases consist of two different components, a verb (e.g., “wash”) and a noun (e.g., “car”), testing can either be implemented as noun‐cued recall of verbs or verb‐cued recall of nouns, which may differently affect later memory performance. In the present study, we investigated the effect of testing for these two recall types, using verbally encoded action phrases as learning materials. Results showed that repeated study–test practice, compared to repeated study–restudy practice, decreased the forgetting rate across 1 week to a similar degree for both noun‐cued and verb‐cued recall types. However, noun‐cued recall of verbs initiated more new subsequent learning during the first restudy, compared to verb‐cued recall of nouns. The study provides evidence that testing has benefits on both subsequent restudy and long‐term retention of action‐relevant materials, but that these benefits are differently expressed with testing via noun‐cued versus verb‐cued recall.     

Use of a structured investigative protocol enhances the quality of investigative interviews with alleged victims of child sexual abuse in Britain

One hundred alleged victims of child sexual abuse (aged 4–13; M = 9.3 years) were interviewed by police investigators about their alleged experiences. Half of the children were interviewed using the National Institute of Child Health and Human Development (NICHD) structured interview Protocol, whereas the other children, matched with respect to their age, relationship with the alleged perpetrator, and seriousness of the alleged offenses, were interviewed by investigators following the Memorandum of Good Practice. Protocol‐guided interviews elicited more information using free‐recall invitations and less information using directive, option‐posing and suggestive questions than did standard Memorandum interviews. There were no age differences in the proportion of total information provided in response to open‐ended invitations in either condition, but there was a significant increase with age in the proportion of central information provided in response to open‐ended invitations.

Effects of program‐advertisement congruity and advertisement emotional appeal on memory for health and safety advertisements

The aim of this study was to examine the memory for health and safety advertisements (HSAs) embedded within a congruent (documentary) or incongruent (sitcom) program. A total of 80 participants aged 16–25 years took part. Participants watched either a sitcom or a health‐related program with health and safety and “filler” advertisements. After they watched the 30 minute program, they were given free and cued recall measures as well as program evaluation. These showed that the free recall scores were generally better for HSAs than filler advertisements across both program types, while the cued recall and advertisement recognition scores were better for filler advertisements than HSAs. Memory scores revealed that the HSAs were better remembered than filler advertisements in an incongruent program environment. Health advertisements are better recalled in non‐health‐related programs. This supported the interference hypothesis.     

Secrecy and suggestibility: are children's memories for secrets less suggestible than other memories?

Adult secrecy research has found a memory‐enhancing effect for information kept secret as the secret is mentally rehearsed each time the adult is required to prevent it being reported (e.g. Lane & Wegner, 1994). The present study examined possible memory‐enhancing effects of children keeping information secret. Two hundred and thirty two five to eight year olds took part in a puppet‐making task. During the task the puppet‐maker sprayed glitter onto the puppets. Half the children were told to keep a secret (that the spray had been taken from Disneyland) and the other half (the control group) were merely told the spray was from Disneyland. One week later the children were interviewed either by the puppet‐maker (the secret‐giver) or by the puppet‐maker's friend (the secret‐novice). The five to six year olds showed no effect of the secret condition, whereas the seven to eight year olds made significantly less errors in their free recall in the secret condition compared to the control condition. There was no effect of the secret condition on children's suggestibility to leading questions. However, both age groups were significantly more suggestible when interviewed by the secret‐giver. Finally, both age groups showed a recall deficit in the secret condition. Copyright © 2004 John Wiley & Sons, Ltd.     

Children's response biases to results of object sharing

This study investigated whether 2- to 6-year-old children exhibit a response bias to questions pertaining to the results of sharing objects that should attract their interest. An experimenter distributed four objects between herself/himself and a child, equally or unequally (more to the child or more to the experimenter) and asked the child yes-no questions: “Is this okay?” and “Is this bad?” The results indicated that 2- and 3-year-olds exhibited a yes bias in all conditions, 4-year-olds exhibited a yes bias to the equal condition and to the unequal condition with more distributed to the child, and 5-year-olds exhibited a yes bias to both unequal conditions, whereas 6-year-olds did not show any response bias. Young preschoolers exhibited a yes bias regardless of questions and children may become able to say both “yes” and “no” appropriately to questions about object sharing after the age of six.     

Retro- and prospection for mental time travel: Emergence of episodic remembering and mental rotation in 5- to 8-year old children

We investigate the common development of children’s ability to “look back in time” (retrospection, episodic remembering) and to “look into the future” (prospection). Experiment 1 with 59 children 5 to 8.5 years old showed mental rotation, as a measure of prospection, explaining specific variance of free recall, as a measure of episodic remembering (retrospection) when controlled for cued recall. Experiment 2 with 31 children from 5 to 6.5 years measured episodic remembering with recall of visually experienced events (seeing which picture was placed inside a box) when controlling for recall of indirectly conveyed events (being informed about the pictures placed inside the box by showing the pictures on a monitor). Quite unexpectedly rotators were markedly worse on indirect items than non-rotators. We speculate that with the ability to rotate children switch from knowledge retrieval to episodic remembering, which maintains success for experienced events but has detrimental effects for indirect information.     

Peer discussion affects children's memory reports

This study explored the memory conformity effect in children. Younger (6–7 years; n = 60) and older (11–12 years; n = 62) children watched a video individually (individual witness condition) or in dyads (co‐witness condition). The dyads believed that they were viewing the same video as the other member of the pair while in fact the saw different versions. Next, children in the individual witness condition answered questions, whereas children in the co‐witness condition discussed the event on the video with each other. Finally, all children completed an individual free and cued recall task. In the co‐witness condition, more than 60% of the children recalled at least one detail from the alternative video, whereas over 23% of the children in the individual witness condition reported such a detail. Moreover, in free recall—but not in cued recall—the memory conformity effect was stronger for older than for younger children. Copyright © 2007 John Wiley & Sons, Ltd.     

The effect of repeated experience on children's suggestibility across two question types

There is a discrepancy in the literature regarding the effect of repeated experience on children's suggestibility. Some researchers have concluded that repeated experience increases children's suggestibility for variable details whereas others have reported no detrimental effect. This study demonstrated that the type of question used to test memory (cued‐recall versus yes/no questions) could account for the different reported conclusions. Children aged 5–6 years took part in an event either once or four times. Three or 21 days later, they were given a suggestive interview about the single/final occurrence of the event during which half of the event details were inaccurately described. When later asked yes/no questions, the children with repeated experience agreed with more of the suggestions than did those in the single‐experience condition, especially at the longer delay. In relation to cued‐recall questions, however, experience did not mediate the number of times that false suggestions from the biasing interview were reported. This latter finding was revealed irrespective of the retention interval. Copyright © 2002 John Wiley & Sons, Ltd.     

Influences of Social Expectations of Gender,Gender Stereotypes,and Situational Constraints on Children's Toy Choices

Children, whose ethnic/racial backgrounds (primarily caucasian) and household compositions (primarily two-parent homes) reflected local population statistics, were videotaped playing with toy dishes and tools. The amount of time spent with each toy was calculated to determine whether this varied as a function of children's perceptions of social expectations of gender, awareness of gender stereotypes, and situational constraints (no information, gender-typed information unrelated to the toys, gender-typed toy labels). In study 1, the toy choices of girls and boys with perceptions of having one or more familiar people who thought cross-gender-typed play was “bad,” were influenced by gender-typed toy labels. However, only boys with perceptions of having one or more people who thought cross-gender-typed play was “bad,” were somewhat influenced by gender-typed information unrelated to the toys. Furthermore, in study 2, boys' (but not girls') perceptions of having one or more people who thought cross-gender-typed play was “bad,” independent of an awareness of gender stereotypes predicted the amount of time boys spent with cross-gender toys. The discussion highlights the utility of measures of children's perceptions of others' social expectations of gender in gender research. Additionally, the discussion highlights the complex relationships between such perceptions, situational constraints, and different socialization that girls and boys experience in the domain of toy play.     

ESTABLISHING GENERATIVE YES/NO RESPONSES IN DEVELOPMENTALLY DISABLED CHILDREN

We evaluated the effects of two procedures for teaching four developmentally disabled children to respond yes/no appropriately. During baseline, tutoring was conducted in which five known items were individually presented with the question, “Is this a_____?”, followed either by access to requested items or by remedial prompting contingent on responding. When tutoring did not improve performance, instruction was embedded in the regular classroom activities. In this condition, items requested by students were either presented or withheld on the basis of their response to the question, “Do you want ______?”. Increases in correa responding were confirmed by a multiple-baseline design across all four students and were maintained with the introduction of new items. However, generalization to “Is this a_____?” questions did not occur in the tutoring setting until specifically programmed. Subsequently, students also demonstrated appropriate yes/no responding to questions involving actions, possession, and spatial relations.     

Dynamics in Using Different Question Types in Estonian Police Interviews of Children

The present study examined Estonian police officers' interviewing tactics with children in cases of physical and/or sexual abuse, as there are no published studies conducted in a country formally part of the Soviet Union. Also, the dynamics in using different question types within interviews was examined. Investigative interviews with 66 children (mean age 8 years 10 months, range 4 to 14 years) were transcribed and analyzed. Option‐posing and direct questions were most frequently employed, but invitations produced significantly more information. Four to seven‐year‐old children were asked more suggestive questions than older children. As interviews progressed, the average number of explanations and general invitations per interview decreased, whereas the number of suggestive and option‐posing questions increased. This study suggests that like police officers in other countries, Estonian investigators require training in structured interviewing methods to increase the number of invitations and reduce reliance upon option‐posing and direct questions.

Eyewitness memory: Balancing the accuracy,precision and quantity of information through metacognitive monitoring and control

Although memory deteriorates over time, people may be able to maintain high accuracy by metacognitively monitoring the quality of their memories and strategically controlling their memory reports. We test two mechanisms of metacognitive control: Exercising a report option (withholding uncertain responses) and adjusting response precision (providing imprecise, but likely accurate, responses). Participants observed a mock crime and were interviewed after 10 minutes or 1 week. Interviews consisted of answerable questions in one of three formats (free narrative, cued recall, yes/no), allowing participants to exert more or less control over their answers. Participants' reports showed tradeoffs between accuracy, quantity and precision of information. Depending on the question format, participants maintained high accuracy even at the delayed report either by opting not to answer (yes/no or cued recall) or by providing imprecise answers (cued recall or free narrative). We discuss implications for experimental research, metacognitive theory and the criminal justice system. Copyright © 2010 John Wiley & Sons, Ltd.     

Stability and consistency of children’s event recall

The purpose of the study was to investigate consistency of recall across different tasks of event recall (similar to eyewitness tasks) and stability of performance across two different events. Additionally, developmental differences in consistency and stability were explored. 6-, 8-, and 10-year-old children were subsequently shown two different events (videos) and were questioned about each event in two separate interviews. For both videos, performance levels in free recall, unbiased cued recall, and suggestibility were at similar levels, with older children generally outperforming younger children. As to intertask consistency of recall, there were significant correlations between correct free recall and correct unbiased cued recall but not between correct free recall and yielding to suggestive questions. All three measures of eyewitness performance showed significant group stability (test-retest correlations) across the two interviews, regardless of age. However, individual stability (lability) was lower, which points to moderate individual differences in stability across the two interviews. The findings are discussed in terms of underlying cognitive skills and the problem of predicting a single child’s memory performance in real cases of eyewitness testimony.     

Age-related differences on a new test of temporal order memory for everyday events

We developed a new test to examine incidental temporal order memory for a self-generated sequence of tasks one might complete in everyday life. Young and older adults were given 10 cards, each listing a task one might accomplish in a typical day. Participants were asked to self-generate a “to do” list by placing the 10 cards in a sequence representing the order in which they would accomplish the tasks, but were not informed of a subsequent memory test. We assessed immediate free recall, delayed free recall, and delayed cued recall for the order of the tasks in the sequence. Older adults were significantly impaired relative to young adults on immediate free recall, delayed free recall, and delayed cued recall. Correlation analyses with standardized neuropsychological tests provide preliminary evidence for construct validity for our test, which is portable and can be rapidly administered in clinical or laboratory settings.
