A large body of research has considered children’s novel word learning from video; however, no known work has compared children’s novel word learning from an educational television show in which the character speaks directly to the child (participatory cues) and a show in which the child overhears two characters speaking to one another (third-party joint attention). Using two professionally produced videos that mimic contemporary children’s television shows, we conducted a 2-condition experiment (= 73) to examine under which condition children were better able to learn a novel word. Results indicated a main effect of condition and age: children in the participatory cues condition and older children demonstrated greater word learning than children in the third-party joint attention condition and younger children. There was an interaction between age and condition, but only among children between the ages of 28.20 and 41.46 months. These findings demonstrate that the participatory cues model, typically used in children’s television programming, is a better model to use to promote children’s word learning. These findings run counter to a similar study that used stimulus videos that did not mimic a children’s program, finding that the third-party joint attention condition was more effective.  相似文献

Little empirical work has explored the relation between destructive sibling conflict and conduct problems in children. This study used a measure of observed sibling conflict to examine its relations with maternal and teacher report of conduct problems in a low-income sample of 180 five-year-old boys and their close-age siblings. Early report of behavior problems and rejecting parenting were added to the analyses to control for these predictors and to examine interactive effects. The interaction between destructive sibling conflict and rejecting parenting predicted aggressive behavior problems across time and informants such that a rise in aggression scores was evident for children who had high levels of both sibling conflict and rejecting parenting. Sibling conflict was also directly related longitudinally to the Child Behavior Checklist Delinquency factor. Results are discussed in terms of additive risk models and G. R. Patterson's (1984, 1986) theory of coercion.  相似文献

Recent literature suggests that different ‘styles’ of homicide will most appropriately be reflected in the different types of behaviours committed by offenders during the crime. In the last few years, there has been a move to standardise classification systems of single homicides and establish their cross‐national generalisability. Literature on serial homicide to date has mostly centred on homicides occurring in the US. However, national differences due to factors such as culture, national identity, political, and socio‐economic circumstances may decrease the applicability of these models or certain aspects thereof in other countries and thus must be evaluated. The present study tested the applicability in the South African context of a recently developed US‐based serial homicide crime scene classification framework. Specifically, this study compared the thematic differentiation in planning and violent behaviours that the offenders engage in and how this differentiation compares with that in the US. The sample consisted of 25 homicides that were in total responsible for the murder of 267 victims. Results indicated that overall, the framework is useful and applicable in the South African sample, but important environmental and contextual constraints must be taken into account.

Key to understanding the significance of behavioural evidence for linkage purposes is in establishing how consistently an offender displays the same or similar behaviours across their series. There have however to date been very few studies aiming at identifying salient components of offending behaviour that can be used reliably for linking individual crimes as part of a single series. In addition, studies that have been conducted have all dealt with serial homicide in the Western world and have been based on small samples of cases from each country. Some of the recent literature has started to disentangle some of these salient features, notably the victim, violence levels, control, and planning. The current study focused on evaluating the consistency of these features across series, using a sample of serial homicides from South Africa consisting of 30 offenders with a total of 283 victims and 235 crime scenes. Results indicate that the level of interaction with the victim may be influential to the stability or instability of offending patterns across the series. How offenders approach planning in their offence also showed a certain degree of consistency, with patterns of violence being the least consistent across the series of all components tested.

Transcranial magnetic stimulation studies have so far reported the results of mapping the primary motor cortex (M1) for hand and tongue muscles in stuttering disorder. This study was designed to evaluate the feasibility of repetitive navigated transcranial magnetic stimulation (rTMS) for locating the M1 for laryngeal muscle and premotor cortical area in the caudal opercular part of inferior frontal gyrus, corresponding to Broca’s area in stuttering subjects by applying new methodology for mapping these motor speech areas. Sixteen stuttering and eleven control subjects underwent rTMS motor speech mapping using modified patterned rTMS. The subjects performed visual object naming task during rTMS applied to the (a) left M1 for laryngeal muscles for recording corticobulbar motor-evoked potentials (CoMEP) from cricothyroid muscle and (b) left premotor cortical area in the caudal opercular part of inferior frontal gyrus while recording long latency responses (LLR) from cricothyroid muscle. The latency of CoMEP in control subjects was 11.75 ± 2.07 ms and CoMEP amplitude was 294.47 ± 208.87 µV, and in stuttering subjects CoMEP latency was 12.13 ± 0.75 ms and 504.64 ± 487.93 µV CoMEP amplitude. The latency of LLR in control subjects was 52.8 ± 8.6 ms and 54.95 ± 4.86 in stuttering subjects. No significant differences were found in CoMEP latency, CoMEP amplitude, and LLR latency between stuttering and control-fluent speakers. These results indicate there are probably no differences in stuttering compared to controls in functional anatomy of the pathway used for transmission of information from premotor cortex to the M1 cortices for laryngeal muscle representation and from there via corticobulbar tract to laryngeal muscles.  相似文献

To investigate the format of mental images and the penetrability of mental imagery performance to top-down influences in the form of gravity information, children (4-, 6-, 8- and 10-year-olds) and adults (N = 112) performed mental rotation tasks. A linear increase in response time with rotation angle emerged at 6-years, suggesting that spatial properties are represented in children’s mental images. Moreover, 6-, 8-, and 10-year-olds, but not 4-year-olds or adults, took longer to respond to rotated stimuli pairs when gravity information was incongruent with the direction of rotation rather than congruent. Overall, findings suggest that in contrast to adults’, 6- to 10-year-olds’ mental rotation performance was penetrated by top-down information. This research (a) provides insight into the format of young children’s mental images and (b) shows that children’s mental rotation performance is penetrable by top-down influences.  相似文献
