The relationship of visual attention to children's comprehension of television.

The study experimentally tested the relationship between visual attention and comprehension of a TV program. 72 5-year-old children watched a 40-min version of the TV program "Sesame Street." Half the children viewed the program in the presence of a variety of toys and half viewed without toys. The children were then tested for their comprehension of the program. Although visual attention to the TV in the no-toys group was nearly twice that in the toys group, there was no difference between the groups in comprehension. There were, nevertheless, significant within-group correlations between visual attention and comprehension even for questions concerning only auditorily presented material. The results were interpreted as indicating that in a normal TV viewing setting, variations in the comprehensibility of the TV program may determine variations in children's attention to the TV.     

Together I Can! Joint Attention Boosts 3- to 4-Year-Olds’ Performance in a Verbal False-Belief Test

Effects of joint attention were addressed on 3- to 4-year-olds’ performance in a verbal false-Belief Test (FBT), featuring the experimenter as co-watcher rather than narrator. In two experiments, children (N = 183) watched a filmed-FBT jointly with a test leader, disjointed from a test leader, or alone. Children attending jointly with a test leader were more likely to pass the FBT compared with normative data and to spontaneously recall information indicating false-belief understanding, suggesting that joint attention strengthens the plausibility of the FBT and renders plot-critical information more salient. In a third experiment (N = 59), results were replicated using a typical, image-based FBT. Overall findings highlight the profound impact of experimenter as social context in verbal FBTs, and link recall of specific story features to false-belief understanding.     

三点前提性认识--关于确立小说中人物"他"的叙述者地位

现代主义小说中以人物“他”的眼光叙述的作品逐渐增多，但由于受现实生活中的言语习惯影响，人们对这个新出现的叙述者“他”不予认可，往往以文本中个别的视角越界和叙述话语不符叙述者身份来否定“他”的叙述者地位。但是我们若把“他”的叙述与第一人称叙述者“我”的叙述加以比较，就可以发现这些否定理由并不能成立。通过比较分析，我们可以得到使“他”的叙述者地位得以认可的三点前提性认识。     

Effects of narrator gender on conceptual learning

Audiovisual materials for nursing students typically show a female nurse demon-strating activities as they are described (and sometimes directed) by a male narrator. Of obvious concern is the effect of such sex stereotyping on female students. Further, do students (male and female) learn as well from instructional video-tapes narrated by an equally competent female narrator? The investigator sought to control all variables but gender of narrator in this study of conceptual learning from videotapes.     

Young children's recall and reconstruction of audio and audiovisual narratives

It has been claimed that the visual component of audiovisual media dominates young children's cognitive processing. This experiment examines the effects of input modality while controlling the complexity of the visual and auditory content and while varying the comprehension task (recall vs. reconstruction). 4- and 7-year-olds were presented brief stories through either audio or audiovisual media. The audio version consisted of narrated character actions and character utterances. The narrated actions were matched to the utterances on the basis of length and propositional complexity. The audiovisual version depicted the actions visually by means of stop animation instead of by auditory narrative statements. The character utterances were the same in both versions. Audiovisual input produced superior performance on explicit information in the 4-year-olds and produced more inferences at both ages. Because performance on utterances was superior in the audiovisual condition as compared to the audio condition, there was no evidence that visual input inhibits processing of auditory information. Actions were more likely to be produced by the younger children than utterances, regardless of input medium, indicating that prior findings of visual dominance may have been due to the salience of narrative action. Reconstruction, as compared to recall, produced superior depiction of actions at both ages as well as more constrained relevant inferences and narrative conventions.     

Development of gender constancy and selective attention to same-sex models.

4 developmental levels of gender constancy were identified in 55 preschool-age children on the basis of a reproducible Guttman scale of answers to sets of questions pertaining to gender identity, gender stability over time, and gender consistency across situations. Children's developmental level of gender constancy was predictive of the amount and the proportion of time they attended to an adult male and an adult female film model. As boys developed gender constancy, their relative preference for watching the male model increased significantly; as girls developed gender constancy, their relative preference for watching the female model increased, though not significantly. At the more advanced levels of gender constancy, boys watched the male model more than did girls. It was suggested that same-sex social learning may develop as a function of children's cognitive understanding of gender as an identifiable, stable and consistent human attribute.     

What It Takes for Preschoolers to Learn Sex Abuse Prevention Concepts

We sought to determine why preschoolers struggle to learn abuse prevention concepts that children only a few years older learn easily. We pretested preschoolers' knowledge of sexual abuse prevention, observed them viewing a widely-used sexual abuse prevention program, then post-tested their abuse prevention knowledge. We micro-measured comprehension of specific prevention concepts during instruction in order to compare failures of comprehension with failures of retention and/or application. We also tested the effectiveness of guided participation with an adult co-viewer as a technique for improving children's comprehension of the material. Although subjects watched 50% of the program, they comprehended only 30%. Viewing did not significantly increase their knowledge. Likewise, the presence of an active adult co-viewer did not increase comprehension of abuse prevention concepts. We identified four audio/visual production features that accounted for 59% of subjects' visual attention. Attention predicted comprehension. Comprehension of advanced concepts was predicated upon comprehension of simpler ones. If subjects failed to comprehend a basic concept, they were significantly less likely to attend to or comprehend more advanced concepts. Preschoolers need sexual abuse prevention programs produced specifically for them. Research should focus on programs that (1) are developmentally graduated, (2) present concepts in a logical order and then seek to ensure that subjects comprehend the concept before moving on, and (3) use audio/visual production features that recruit and maintain visual attention.     

Developmental Changes in Attention and Comprehension Among Children With Attention Deficit Hyperactivity Disorder

Changes in visual attention and story comprehension for children (N = 132) with attention deficit hyperactivity disorder (ADHD) and comparison peers were examined. Between the ages of 7 and 9 (Phase 1) and approximately 21 months later (Phase 2), children viewed 2 televised stories: 1 in the presence of toys and 1 in their absence. Both groups of children showed developmental increases in visual attention and stable group differences over time. Deficits in comprehension among children with ADHD, however, increased over time. Whereas comparison children’s recall of factual and causal information increased over time in both viewing conditions, children with ADHD showed no developmental improvement in recall of factual information in the toys‐present condition and no improvement in recall of causal relations in either viewing condition.

Memory for Gender-Consistent and Gender-Inconsistent Event Sequences by Twenty-Five-Month-Old Children

Gender-schema theory predicts that, based on a rudimentary understanding of gender (e.g., self-labeling), children will invoke gender schemata in the processing of information. In older children, one indication of schematic processing is differential memory for schema-consistent versus schemainconsistent material. Due to a lack of appropriate measures, evidence of very early use of gender schemata has been limited. In the present study, elicited imitation was used to assess 25-month-old girls' and boys' immediate and delayed recall of sequences depicting femalestereotyped, male-stereotyped, and gender-neutral activities. At immediate and delayed testing, girls showed equivalent levels of recall of all 3 sequence types. Boys showed superior recall of male- relative to female-stereotyped sequences; their recall of gender-neutral sequences was equivalent to that of male-stereotyped ones. Results indicate that, at least for boys, use of gender schemata is evident by 25 months of age. Possible explanations for the absence of a clear effect for girls are discussed.     

Efficacy of an Intervention Program for Attention and Reflexivity in Children With Attention Deficit Hyperactivity Disorder

There has been increasing evidence in recent years of the need to adapt intervention programs to the specific needs of children with attention deficit hyperactivity disorder (ADHD). The main goal of this research work was to study the efficacy of an educational intervention program to improve attention and reflexivity in school children with ADHD in order to verify the improvements in symptoms associated with ADHD such as aggressivity, social isolation, anxiety, and attention deficit. The sample was comprised of 26 primary school children ranging from 7 to 10 years of age with ADHD. Symptoms of children with ADHD were evaluated by applying the Escalas Magallanes Screening Scale for Attention Deficits and Other Developmental Problems in Children (EMA‐DDA) at two time points (pre and post). The results show a statistically significant reduction in symptoms on the aggressivity and social isolation scales measured with the EMA‐DDA after applying the intervention program. These data supports the potential value of an intervention program for working with ADHD children.     

Television viewing at home: age trends in visual attention and time with TV

The TV-viewing behavior of 99 families with young children was videotaped by automated time-lapse recording equipment placed in homes for 10-day periods. The 99 families comprised 460 individuals from infants to 62 years of age. Time-sample analyses of 4,672 hours of recordings indicated that the TV-viewing room contained no viewers 14.7% of the time that the TV was on. There were no age trends in time spent with television. Percent visual attention to television increased greatly across the preschool years, leveled off at about 70% during the school-age years, and declined in adulthood. Men looked at the TV more than women. There were no significant correlations between time spent with TV and percent of visual attention to TV. The increase in visual attention to television during the preschool years is consistent with the theory that TV program comprehensibility is a major determination of attention in young children.

Effect of on-screen text on multimedia learning with native and foreign-accented narration

This study examined the impact of redundant on-screen text on learning from an animated PowerPoint presentation, narrated either by a native or a foreign-accented narrator, with no text, summary text, or full text. Participants completed retention and transfer tests and rated the cognitive load induced by the narration and the PowerPoint materials. With a native narrator, participants performed better on transfer with no text than summary text (redundancy effect). The foreign-accented narration was perceived to be more difficult to understand. Transfer performance was worse for accented than native narration with no text, replicating a voice effect. With a foreign-accented narrator, participants performed better on retention with full text than summary text. Full text facilitated decoding of the accented narration at the word level, but it did not facilitate deep processing for knowledge transfer. The results are discussed in the context of cognitive load and the cognitive theory of multimedia learning.     

Seeing, hearing, and doing: a developmental study of memory for actions

The ability to recall and organize actions was studied in children from 5 to 11 years in age. 8 different auditory or visual commands were successively presented for 10 trials in each modality in a free-recall task. Younger children performed fewer commands but recalled relatively more recent ones, and they showed the same degree of subjective organization and the same degree and structure of hierarchical clustering as the older children. The hierarchical structure was independent of recall, age, and modality, with the motor actions being organized by the locus of the object or instrument of the verb in the command. The difficulty of the commands was highly correlated with uncertainty of the locus of the action, that is, the number of possible arguments (objects or instruments) a verb could assume, as measured by a subsidiary experiment on 8-year-olds who were asked to name as many parts of the body upon or with which one could perform each action. Developmental differences in recall appear to rise because of primary organization (retrieval) and rehearsal strategies rather than secondary organization.     

Gender differences in preschool children’s recall of competitive and noncompetitive computer mathematics games

This study investigated whether competitive and noncompetitive educational mathematics computer games influence four‐ to seven‐year‐old boys’ and girls’ recall of game‐playing experience. A qualitative analysis was performed to investigate what preschool children may have learned through their selective recall of game‐playing experience. A difference emerged in six‐ to seven‐year‐old boys’ and girls’ recall after playing a competitive computer mathematics game, such that boys tended to first recall the consequence of ‘winning and losing’ whereas girls of the same age focused on ‘friendship among animated characters’ in the game. Thus, the qualitative results suggest the possibility that selective attention or selective recall might be partially influenced by gender schemas. Based on the recall sequences, educational noncompetitive computer mathematics games may lead to a better learning outcome for older boys.
