Girls Arrested for Murder: An Empirical Analysis of 32 years of U.S. Data by Offender Age Groups

Most studies on juvenile homicide offenders (JHOs) have used small samples and have concentrated on adolescent male offenders. As a result, little is known about the population of female juveniles arrested for murder. This study utilized the Supplementary Homicide Report (SHR) database to investigate age differences between younger (aged 6–12 years) and older (aged 13–17 years) females arrested for murder in the United States from 1976 to 2007. As predicted, six variables used to test seven hypotheses with respect to younger and older female JHOs in single victim incidents were significant (victim age, victim gender, victim offender relationship, murder weapon, offender count, and homicide circumstance). Regression analysis revealed that younger girls were seven times more likely than older girls to kill children aged 0–12 years. Girls aged 6–12 years were five times more likely than their teen counterparts to be involved in conflict‐related homicides as opposed to crime‐related homicides. Although approximately the same percentages of younger and older girls killed infants under the age of 1, the victims were significantly different for the two offender age groups. This article concludes with a discussion of our findings and directions for future research. Copyright © 2014 John Wiley & Sons, Ltd.     

Children's eyewitness reports after exposure to misinformation from parents

This study examined how misleading suggestions from parents influenced children's eyewitness reports. Children (3 to 8 years old) participated in science demonstrations, listened to their parents read a story that described experienced and nonexperienced events, and subsequently discussed the science experience in two follow-up interviews. Many children described fictitious events in response to open-ended prompts, and there were no age differences in suggestibility during this phase of the interview. Accuracy declined markedly in response to direct questions, especially for the younger children. Although the older children retracted many of their false reports after receiving source-monitoring instructions, the younger children did not. Path analyses indicated that acquiescence, free recall, and source monitoring all contribute to mediating patterns of suggestibility across age. Results indicate that judgments about the accuracy of children's testimony must consider the possibility of exposure to misinformation prior to formal interviews.     

Children as Earwitnesses: Memory for Emotional Auditory Events

We examined the influence of age and emotionality of auditory stimuli on long‐term memory for environmental sound events. Sixty children aged 7–11 years were presented with two environmental sound events: an emotional car crash and a neutral event, someone brushing their teeth. The sound events comprised six individual environmental sounds, and the participants passively listened to the sound events through a headset. After a two‐week delay, participants performed a cued recall task and a recognition task. Independent of age, children were notably poor at recalling the sound events. Children recalled and recognized significantly more sounds from the emotional sound event than the neutral sound event. Additionally, the older children performed the recall task better than the younger children. The present findings confirm and expand the previously reported superiority of emotional material in memory.Copyright © 2016 John Wiley & Sons, Ltd.     

儿童视听觉通道现实监控的发展

采用视觉图片和动画,听觉声音和词语任务,分别要求5岁（平均年龄66.5个月）、7岁（平均年龄80.8个月）和9岁（平均年龄117.2个月）共233名儿童在知觉和想象材料中作出来源判断,比较现实监控任务中视听觉通道之间和通道内部的发展差异。结果发现,在通道内部,不同实验材料对现实监控的影响不尽相同。在视觉通道内部：较小年龄儿童对图片的现实监控好于动画,较大年龄儿童对动画的现实监控好于图片;在听觉通道内部：儿童对声音的现实监控好于词。随着年龄的增长,对记忆现实监控的通道差异从视觉的图片刺激优势到图片和动画优势,到视觉刺激和声音对词的优势。文章还讨论了这些发展差异的可能原因,对我们理解个体记忆发展的规律和特点以及对实践的指导意义     

Parent-to-child physical aggression,neighborhood cohesion,and development of children's internalizing and externalizing

Taking a risk and resilience approach, this study examined (1) whether child age moderates the association between exposure to parent–child physical aggression (PCPA) and initial levels and growth in internalizing and externalizing problems, and (2) whether neighborhood social cohesion is a protective factor for children who experience PCPA. Data came from 2810 caregivers of children aged 3–15 who participated in the Project on Human Development in Chicago Neighborhoods (PHDCN). Multilevel growth models showed that age moderated PCPA's association with internalizing problems, such that the association was stronger in older children than in younger children. Age also moderated PCPA's association with externalizing problems, such that the association was stronger in younger children than in older children. Neighborhood cohesion partially attenuated the association between PCPA and internalizing but only for older children; living in a neighborhood characterized by high cohesion mitigated levels of internalizing for maltreated children aged 11 years and older.     

Reading the road: The influence of age and sex on child pedestrians' perceptions of road risk

The United Kingdom has one of the highest records of child pedestrian accidents in the European Union, and statistics show boys are particularly vulnerable. This study investigated whether there were identifiable developmental or sex differences in the perception of road risk, which might explain the occurrence of such child pedestrian accidents. The study was a between‐participants experimental design with three independent variables: age, sex and task. The sample comprised 119 school children in three age groups (7–8 years; 9–10 years and 11–12 years) with equal sex distribution in each age group. All children, tested individually, completed two sorting tasks. The tasks differed in that children first classified 20 photographs of road scenes on self‐selected criteria (free sort) and then reclassified the scenes on the basis of safety of each scene (cued sort). When children operated a free sort, age differences were apparent in both the number and type of categories produced. However, this age variation was not apparent for the cued sort showing that the younger children were strongly influenced by cueing. Younger children exhibited a more personal and idiosyncratic perspective of the road compared to older children, who were able to view the road from global perspectives. Sex differences in assessing safety were limited but interesting, demonstrating that the males focussed on physical attributes of the scene and females on the actors within the scene. The focus of females on the dynamic attributes of the scene may be a partial explanation of their greater safety record compared to their male peers.     

Characteristics of personally important episodic memories,counterfactual thoughts,and future projections across age and culture

We have limited knowledge as to whether the phenomenological differences between episodic memories, counterfactuals, and future projections show the same pattern across age groups and diverse samples. Here we compared the characteristics of these mental events, reported by younger and older participants in a Turkish (Study 1) and in an American sample (Study 2). In both studies, memories contained more sensory-perceptual-spatial details, were easier to bring to mind, and more specific. Future projections were the most positive, whereas counterfactuals were the least emotionally intense. In Study 1, older participants rated the events more positively and experienced them with more perceptual detail, whereas younger participants reported the future to be more voluntarily rehearsed, important, and central. These age differences did not replicate in Study 2. Overall, phenomenological differences between the events are robust and replicate across diverse samples. However, age differences are more sensitive to cultural or individual differences.     

The susceptibility of young preschoolers to source similarity effects: Confusing story or video events with reality

This study examined children’s tendency to confuse events that varied in source similarity, which was manipulated using different media of event presentation. In Experiment 1, children in two age groups (3- and 4-year-olds and 5- and 6-year-olds) experienced a live presentation of an event, and another event was either heard from a story (low similarity group) or seen on a video (high similarity group). Immediately afterward, the children were asked to monitor the source of the events. The children in the low similarity group produced higher source discrimination scores than did the children in the high similarity group. Overall, the older children were better at source monitoring than were the younger children. In Experiment 2, the procedure was replicated except that the children’s source monitoring was tested after a 4-day delay. When attributing the source of the story or video events, both 3- and 4-year-olds and 5- and 6-year-olds in the low similarity group produced more accurate story or video attributions than did their age mates in the high similarity group. However, when attributing the source of the live events, only the 3- and 4-year-olds evidenced this effect of source similarity. The 5- and 6-year-olds in both the low and high similarity groups performed at ceiling levels for live discriminations.     

Young children's understanding of pretend crying: The effect of context

Reasoning about another's pretend and real crying is related to ma'ny important social cognitive abilities (e.g., emotional understanding, appearance–reality, and theory of mind). This study investigated whether children aged 6 years and younger could distinguish between instances of pretend crying and real crying as presented in stories. Sixty‐five Japanese children aged 4–6 years were given stories within two contexts (Play and Non‐play). In the Play context, the protagonist of the story was pretending to cry or really crying during a pretend play activity. In the Non‐play context, the protagonist was also pretending to cry or really crying after his/her toy had been hidden by another child. The children answered questions about these crying events. The results showed that the 4‐ and 5‐year‐olds showed significantly better understanding of pretend crying in the Play context compared to the Non‐play context. In the Non‐play context, they were significantly less likely to understand the cause of pretend crying compared to the 6‐year‐olds. The results suggest that the context of pretend play facilitates the children's understanding of pretend crying.     

Lifespan differences in cortical dynamics of auditory perception

Using electroencephalographic recordings (EEG), we assessed differences in oscillatory cortical activity during auditory‐oddball performance between children aged 9–13 years, younger adults, and older adults. From childhood to old age, phase synchronization increased within and between electrodes, whereas whole power and evoked power decreased. We conclude that the cortical dynamics of perceptual processing undergo substantial reorganization from childhood to old age, and discuss possible reasons for the inverse relation between age trends in phase synchronization and power, such as lifespan differences in neural background activity, or a lifespan shift from rate coding in children to temporal coding in adults.     

Effect of varying alarm schedules on acquisition and relapse parameters in the conditioning treatment of enuresis

Acquisition and relapse rates for 178 enuretic children were examined as a function of varying intermittent alarm schedules ranging from the standard (100%) bell-and-pad conditioning alarm treatment to a variable-ratio (VR) alarm schedule of 30–59%. Median follow-up time was 25 months. Children who experienced multiple wetting (MW) events beyond the third treatment week experienced twice as many wettings to reach dryness criterion as non-multiple wetting (NMW) children. Approximately one-third of the sample proved to be MW children. Optimal relapse results for NMW children were achieved with the 70–79% VR alarm schedule (10% relapse rate). MW children treated with the standard experienced a 100% relapse rate. For MW children the lowest relapse rates were attained with a 60–69% VR schedule (42% relapse). Older children experienced higher relapse rates than younger children, but age differences were eliminated with a 70–79%, VR alarm schedule. Collectively, the results demonstrate optimal VR intermittent alarm schedules for differen: categories of enuretic children.     

The development of early literacy in Steiner‐ and standard‐educated children

Background. There is evidence that children who are taught to read later in childhood (age 6–7) make faster progress in early literacy than those who are taught at a younger age (4–5 years), as is current practice in the UK. Aims. Steiner‐educated children begin learning how to read at age 7, and have better reading‐related skills at the onset of instruction. Therefore, it is hypothesized that older Steiner‐educated children will make faster progress in early literacy than younger standard‐educated controls. Samples. A total of 30 Steiner‐educated children (age 7–9) were compared to a matched group of 31 standard‐educated controls (age 4–6). Method. Children were tested for reading, spelling, phonological awareness, and letter knowledge at three time points during their first year of formal reading instruction and again at the end of the second year. Results. There were no significant differences between groups in word reading at the end of the first and second year or reading comprehension at the end of the second year; however, the standard group outperformed the Steiner group on spelling at the end of both years. The Steiner group maintained an overall lead in phonological skills while letter knowledge was similar in both groups. Conclusions. The younger children showed similar, and in some cases, better progress in literacy than the older children; this was attributed to more consistent and high‐quality synthetic phonics instruction as is administered in standard schools. Consequently, concerns that 4‐ to 5‐year‐olds are ‘too young’ to begin formal reading instruction may be unfounded.     

“Eat your Hamburger!”—“No, I don’t Want to!” Argumentation and Argumentative Development in the Context of Dinner Conversation in Twenty Swedish Families

The aim of the present study was to analyse family dinners as context of argumentation and argumentative development by using a context-sensitive model of basic argumentative structures in every day conversations. The data consisted of 40 argumentative sequences in dinner conversations in twenty Swedish families with children aged 7 to 17 years. The families were divided in two groups depending on the children's ages (10–11 years with younger siblings and 10–12 years with older siblings). The model revealed characteristic structures of argumentation appearing as co-text and suggested differences between family groups depending on contextual factors such as age of the children. The groups of older children produced longer argumentative sequences, more exchanges per sequence and higher rate of turns. The older children also engaged in non-instrumental deliberations and disputations significantly more often and they performed more elaborated expansions (through a higher quantity of backing arguments). The groups of younger children on the other hand were more often involved in negotiations on topics relevant in the immediate context. Less expected was, however, the lack of more complex and varied arguments, even in the groups of older children.     

Age Discrimination in the Evaluation of Job Applicants

This study investigated the nature of age discrimination against older job applicants. One hundred fifty‐six participants (102 students; 54 organization based) evaluated a hypothetical job applicant's (aged 33–66 years) work‐related competences and likelihood of being hired. Applicant age affected hiring decisions for both samples where there was a preference for hiring applicants aged 42–48 years. Applicants at both the older and younger ends of the continuum were less likely to be hired, with the oldest applicants (over 54 years) being the least likely to be hired. Although the applicants' age negatively affected evaluations of their trainability and sociability, the effect of applicant age on hiring evaluations was not mediated by these work‐related competencies, suggesting that age discrimination occurs via direct bias against older workers.     

Age-related deficits in reality monitoring of action memories

The authors describe 3 theoretical accounts of age-related increases in falsely remembering that imagined actions were performed (A. K. Thomas & J. B. Bulevich, 2006). To investigate these accounts and further explore age-related changes in reality monitoring of action memories, the authors used a new paradigm in which actions were (a) imagined only, (b) actually performed, or (c) both imagined and performed. Older adults were more likely than younger adults to misremember the source of imagined-only actions, with older adults more often specifying that the action was imagined and also that it was performed. For both age groups, illusions that the actions were only performed decreased as repetitions of the imagined-only events increased. These patterns suggest that both older and younger adults use qualitative characteristics when making reality-monitoring judgments and that repeated imagination produces richer records of both sensory details and cognitive operations. However, sensory information derived from imagination appears to be more similar to that derived from performance for older adults than for younger adults.     

The influence of aging on preferences for sequences of mixed affective events

Research on preferences among sequences of mixed affective events has mostly used young adults as participants. Given differences due to aging in people's ability to regulate emotion, one could expect differences due to aging in preferences for different sequences. Study 1 demonstrated age‐related differences in how older adults (age 65 and older) versus young adults (age 18–25) choose to order mixed affective events that will occur over time. The tendency to choose sequences in which the final event is positive was greater among older adults versus young adults. And, more so than young adults, older adults preferred that the positive and negative events in a sequence be separated in time by a neutral event. Studies 2–3 investigated age‐related differences in overall retrospective evaluations of presented sequences of mixed affective events. In contrast to young adults, older adults' retrospective evaluations were not affected by: (1) whether the final trend of the sequence improved monotonically; (2) whether the last event in the sequence was positive; or (3) the temporal proximity of positive and negative events in the sequence. Results of Study 3 suggest that these age‐related differences are due to differences in older (vs. young) adults' ability to regulate emotion. Copyright © 2010 John Wiley & Sons, Ltd.     

Children's memory of recurring events: is the first event always the best remembered?

Three experiments were conducted to examine the effect of age (4–5 and 6–8 years) and retention interval on children's ability to remember separate occurrences of a repeated event that varied in terms of content (items, dialog, etc.) Experiment 1 explored children's ability to recall the first versus last occurrence of a series of six events, at either one week or six weeks delay. Experiments 2 and 3 explored children's ability to identify the position of items in terms of their order of presentation within the series across two retention intervals. Overall, the results revealed clear age differences in children's performance. In general, the 6‐ to 8‐year‐old children performed better on all tasks than the 4‐ to 5‐year‐old children. Further, the older children showed relatively good memory of the first and last items compared to the middle items, although the last items were more likely to be forgotten or misplaced in the sequencing tasks over time than the first items. For the younger children, the patterns of results were sometimes but not always consistent with that of the older children. The relevance and generalisability of these findings to the legal setting are discussed as well as directions for future research. Copyright © 2002 John Wiley & Sons, Ltd.
