Child-Witness and Defendant Credibility: Child Evidence Presentation Mode and Judicial Instructions,

JOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 9 2001
Tania E. Eaton
Child-witness presentation mode, judicial instructions, and deliberation stage effects on juror ratings of child witness and defendant were investigated Perceptions of the impact of presentation mode on witnesses, juror task, and justice also were explored. Participants (N= 108) viewed a simulated child sexual abuse trial videotape. Overall child-witness credibility was significantly more positive with videodeposition or court-given child evidence than with videolink. The defendant was seen as more definitely guilty when child testimony was court given than by videodeposition or videolink. Presentation mode also significantly influenced perceived impact on child witness, defendant case, and juror task. Judicial instructions interacted with presentation mode to affect perceptions of impact on child witness and juror task. Findings are discussed in relation to previous research, and implications for future research and practice are outlined. [source]

The changing faces of Streptococcus antigen I/II polypeptide family adhesins

MOLECULAR MICROBIOLOGY, Issue 2 2010
L. Jeannine Brady
Summary Streptococcus mutans antigen I/II (AgI/II) protein was one of the first cell wall-anchored adhesins identified in Gram-positive bacteria. It mediates attachment of S. mutans to tooth surfaces and has been a focus for immunization studies against dental caries. The AgI/II family polypeptides recognize salivary glycoproteins, and are also involved in biofilm formation, platelet aggregation, tissue invasion and immune modulation. The genes encoding AgI/II family polypeptides are found among Streptococcus species indigenous to the human mouth, as well as in Streptococcus pyogenes, S. agalactiae and S. suis. Evidence of functionalities for different regions of the AgI/II proteins has emerged. A sequence motif within the C-terminal portion of Streptococcus gordonii SspB (AgI/II) is bound by Porphyromonas gingivalis, thus promoting oral colonization by this anaerobic pathogen. The significance of other epitopes is now clearer following resolution of regional crystal structures. A new picture emerges of the central V (variable) region, predicted to contain a carbohydrate-binding trench, being projected from the cell surface by a stalk formed by an unusual association between an N-terminal ,-helix and a C-terminal polyproline helix. This presentation mode might be important in determining functional conformations of other Gram-positive surface proteins that have adhesin domains flanked by ,-helical and proline-rich regions.

In-court versus out-of-court testimonies: Children's experiences and adults' assessments

APPLIED COGNITIVE PSYCHOLOGY, Issue 7 2010
Sara Landström
The study examined the effects of different presentation modes on child witnesses' experiences and adults' perception and assessments of the same witnesses. Child witnesses (N,=,108) were interviewed about an event that they had either experienced or imagined. Adult mock jurors (N,=,240) watched the children's testimonies live, via two-way closed-circuit television (CCTV), or via a pre-recorded video. The results showed that the live observers perceived the children in more positive terms than did the two-way CCTV observers, who in turn perceived the children in more positive terms than did the video observers. Briefly, it seems as the more proximal the presentation mode, the more positive the observers' perception. Somewhat in contrast to these results, a significantly smaller proportion of the children who testified on video stated that they were nervous, compared to the children who testified live or via two-way CCTV.

Affecting the perception of verbal cues to deception

APPLIED COGNITIVE PSYCHOLOGY, Issue 1 2003
Leif A. Strömwall
An important but overlooked factor in deception detection research is how the perception of verbal cues to deception can be affected by situational factors. This study examined how participants' (N,=,200) perceptions were influenced by presentation mode (Experiments 1 and 2) and repeated exposure/assessment (Experiment 3). As predicted, presentation mode affected the perception of several verbal cues. Participants who watched a videotaped testimony rated the degree of the cues richness of detail, completeness, logical structure and plausibility, higher than those who read the transcript of the same testimony. Furthermore, repeated exposure to the testimony, in combination with repeated assessments, lowered the participants' ratings of the verbal cues. People's perception of the verbal content of a testimony can thus be affected by situational factors. The results are discussed in psycho-legal terms. Copyright © 2002 John Wiley & Sons, Ltd.

Language dominance assessment by means of fMRI: Contributions from task design, performance, and stimulus modality

JOURNAL OF MAGNETIC RESONANCE IMAGING, Issue 5 2001
Margret Hund-Georgiadis MD
Abstract We investigated the influence of different task demands, task designs, and presentation modalities on the functional MRI activation patterns during a language lateralization task in a group of 14 right-handed control subjects. A word classification task was presented as target task appropriate to evoke language-related activation in the inferior frontal gyrus (IFG). The choice of the contrasting baseline task was demonstrated to have a major impact on the functional outcome: While a fixation baseline elicited activations in the inferior frontal gyrus of both hemispheres, a nonsemantic perceptual control task helped to isolate the relevant target task of word classification. The modality of stimulus presentation did not influence the functional data: Auditory and visual presentation modes broadly evoked activations in similar brain regions during word classification. Minor differences in task performance and the side of the responding hand did not interfere with the functional activation patterns of the target task. On the basis of our results, a protocol of functional lateralization in the inferior frontal gyrus is suggested. J. Magn. Reson. Imaging 2001;13:668,675. © 2001 Wiley-Liss, Inc. [source]

The effectiveness of multimedia programmes in children's vocabulary learning

BRITISH JOURNAL OF EDUCATIONAL TECHNOLOGY, Issue 1 2009
Joana Acha
The present experiment investigated the effect of three different presentation modes in children's vocabulary learning with a self-guided multimedia programmes. Participants were 135 third and fourth grade children who read a short English language story presented by a computer programme. For 12 key (previously unknown) words in the story, children received verbal annotations (written translation), visual annotations (picture representing the word), or both. Recall of word translations was better for children who only received verbal annotations than for children who received simultaneously visual and verbal annotations or visual annotations only. Results support previous research about cognitive load in e-learning environments, and show that children's learning processes are hindered by limited working memory. This finding implies a challenge for multimedia programmes designed for children and based on self-regulated learning. [source]
