Effects of television preplay formats on children's attention and story comprehension

Childrens' visual attention to, and comprehension of, a television program was measured as a fucntion of inserts called preplays that varied on two orthogoal dimensions: (1) Presence or absence of visual excerpts from the program, and (2) concrete or inferential story narration. Visual fixation was coded continously for 64 pairs of same-sex children, in 1st 4th grades, while they viewed the television program with one of four types of prepalys. After veiwing, each child answered items assessing his or her comprehension of the visual and verbally presented content. Children who viewed visual preplays attended longer than did children who viewed nonvisual preplays. Visual presentation predicted comprehension of content presented in a visual mode, whereas inferential narration predicted comprehension of implicit content presented in a verbal mode. The results suggest that information processing is modality specific: Visual presentation affects visual processing and abstract language affects verbal processing. The results do not suport the hypothesis that visual presentation interfere with linguistic processing.     

The selective use of sound effects and visual inserts for children's television story comprehension

Sound effects were inserted in a television program in order to guide children's selective attention to, and comprehension of, significant story content. Sixty-four children, equally distributed by sex and by kindergarten and fifth grades, were randomly assigned to one of four treatment conditions that crossed two levels of sound effects with two levels of visual inserts. One-s sound effects either preceded or did not precede three key program transitions. The visual insert conditions provided additional information at these program points whereas the no visual insert conditions did not. Visual attention was videotaped during each child's individual viewing session. After viewing, each child answered a 22-item multiple-choice recognition test of inferential, central, and incedental content. As predicted, sound effects increased selective attention and inferential recognition, particularly for the youngest children who have the greatest difficulty understanding televised stories.     

Implicit semantic priming in Spanish-speaking children and adults: an auditory lexical decision task

Although receptive priming has long been used as a way to examine lexical access in adults, few studies have applied this method to children and rarely in an auditory modality. We compared auditory associative priming in children and adults. A testing battery and a Lexical Decision (LD) task was administered to 42 adults and 27 children (8;1-10; 11 years-old) from Spain. They listened to Spanish word pairs (semantically related/unrelated word pairs and word-pseudoword pairs), and tone pairs. Then participants pressed one key for word pairs, and another for pairs with a word and a pseudoword. They also had to press the two keys alternatively for tone pairs as a basic auditory control. Both groups of participants, children and adults, exhibited semantic priming, with significantly faster Reaction Times (RTs) to semantically related word pairs than to unrelated pairs and to the two word-pseudoword sets. The priming effect was twice as large in the adults compared to children, and the children (not the adults) were significantly slower in their response to word-pseudoword pairs than to the unrelated word pairs. Moreover, accuracy was somewhat higher in adults than children for each word pair type, but especially in the word-pseudoword pairs. As expected, children were significantly slower than adults in the RTs for all stimulus types, and their RTs decreased significantly from 8 to 10 years of age and they also decreased in relation to some of their language abilities development (e.g., relative clauses comprehension). In both age groups, the Reaction Time average for tone pairs was lower than for speech pairs, but only all adults obtained 100% accuracy (which was slightly lower in children). Auditory processing and semantic networks are still developing in 8-10 year old children.     

Comprehension of idiomatic expressions in Japanese—Auditory and visual presentations

This study reports on the auditory and visual comprehension of Japanese idioms having both literal and figurative meanings. Experiment I conducted the rating of the semantic distance between the two meanings. Experiment II investigated the difference of comprehension between semantically far and close idioms. Here the materials are presented in isolation both auditorily and visually. Experiment III conducted the same investigation as Experiment II, except that idioms were presented embedded in literally and figuratively induced contexts. Experiment IV reinvestigated the findings obtained from the previous experiments. The results of these experiments show that in isolation visual presentation precedes auditory presentation, and that both in the auditory and visual presentations semantically far idioms are comprehended more accurately than semantically close idioms.     

PRESCHOOL CHILDREN'S VISUAL ATTENTION TO ATTRIBUTES OF TELEVISION

Preschool children's visual attention to nearly three hours of a heterogeneous sample of children's programing was examined in relationship to the presence of 37 simple visual and auditory attributes of television programs. A factor analysis of the attributes indicated that they were largely independent, with the exception of two factors, which were labeled “women and children” and “puppets.” Attributes and factors that were positively related to attention were the puppet factor, women and children factor, auditory changes, peculiar voices, movement, cuts, sound effects, laughter, and applause. Attributes that were negatively related to attention were adult male voices, extended zooms and pans, eye contact, and still shots. Other attributes had both positive and negative effects on attention depending on whether the child was looking at the TV at the time the attribute occurred. It is suggested that attributes are positive or negative to the degree to which they signal informative comprehensible content.     

Does the Conners' Continuous Performance Test Aid in ADHD Diagnosis?

The performance of clinic-referred children aged 6–11 (N = 100) was examined using the Conners' Continuous Performance Test (CPT) and measures of auditory attention (Auditory Continuous Performance Test; ACPT), phonological awareness, visual processing speed, and visual-motor competence. The Conners' CPT overall index was unrelated to measures of visual processing speed or visual-motor competence. Although the Conners' CPT converged with the ACPT, the latter demonstrated age and order effects. Significant variance in Conners' CPT parameters was predicted by phonological awareness measures, suggesting that Reading Disordered (RD) children could be false positives on the Conners' CPT. The Conners' CPT overall index, phonological awareness, and visual-motor measures were submitted to a 2×2 MANCOVA (ADHD vs. RD, covarying for age and socieoeconomic status): a main effect for RD status was found. Children with ADHD did not have higher Conners' CPT scores than did clinical controls; however, children with Reading Disorders did. Phonological measures distinguished RD children from ADHD children and other clinical controls. ADHD children who failed the Conners' CPT were rated by teachers as more hyperactive. Despite the strengths of the Conners' CPT, its utility for differential diagnosis of ADHD is questioned.     

Prenatal cocaine exposure and infant cognition

The present study examined the relationship of prenatal cocaine exposure to infant information processing in the first year of life.In a prospective, longitudinal study of 177 cocaine-exposed and 175 non-exposed infants, the Fagan Test of Infant Intelligence (FTII) was used to measure attention, visual recognition memory and information processing speed at 6.5 and 12 months of age. Groups were compared over time using mixed linear model analyses.Prenatal cocaine exposure predicted poorer visual recognition memory at 12 months, with exposed infants obtaining lower mean scores and a higher percentage of scores in the risk range. Across exposure groups, information processing speed increased with age, demonstrating a developmental effect. Tobacco and marijuana exposures were related to faster looking times, which did not relate to visual recognition memory.Cognitive deficits and attentional problems noted in prior studies of cocaine-exposed children at later ages may be detectable in infancy.     

Autism and attention deficit hyperactivity disorder: assessing attention and response control with the integrated visual and auditory continuous performance test.

Symptoms of attention deficit hyperactivity disorder (ADHD) have been widely reported in children with autism spectrum disorder (ASD). The current study investigated attention and response control in children with ASD, ADHD, and typical development using the Integrated Visual and Auditory Continuous Performance Test. Results indicate that many children with ASD show significant deficits in visual and auditory attention and greater deficits in impulsivity than children with ADHD or typical development. These findings suggest that many of the children with ASD demonstrate significant ADHD-like deficits. These findings are discussed in the context of symptoms, subtypes, and comorbidity.     

Effects of test order and modality on sustained attention in children with epilepsy.

Neurological conditions affect sustained attention, but the effects of modality and interactions with test order have not been examined. In a 2 x 2 (Order x Modality) design using 54 children with chronic epilepsy, performance was compared on an auditory measure (modified Seashore Rhythm Test) versus a visual measure of attention (modified Conners' Continuous Performance Test). Auditory scores were worse than visual, F(1, 52) = 98.93, p<.001, but there was no order effect or interaction (p>.05). Implications for assessment and intervention are discussed.     

Sport stacking in auditory and visual attention of grade 3 learners

The effect of sport stacking on auditory and visual attention in 32 Grade 3 children was examined using a randomised, cross-over design. Children were randomly assigned to a sport stacking (n=16) or arts/crafts group (n=16) with these activities performed over 3 wk. (12 30-min. sessions, 4 per week). This was followed by a 3-wk. wash-out period after which there was a cross-over and the 3-wk. intervention repeated, with the sports stacking group performing arts/crafts and the arts/crafts group performing sports stacking. Performance on the Integrated Visual and Auditory Continuous Performance Test, a measure of auditory and visual attention, was assessed before and after each of the 3-wk. interventions for each group. Comparisons indicated that sport stacking resulted in significant improvement in high demand function and fine motor regulation, while it caused a significant reduction in low demand function. Auditory and visual attention adaptations to sport stacking may be specific to the high demand nature of the task.     

Crossmodal spatial attention shift produced by centrally presented gaze cues1

Abstract: Despite previous failures to identify visual‐upon‐auditory spatial‐cuing effects, recent studies have demonstrated that the abrupt onset of a lateralized visual stimulus triggers a shift of spatial attention in response to auditory judgment. Nevertheless, whether a centrally presented visual stimulus orients auditory attention remained unclear. The present study investigated whether centrally presented gaze cues trigger a reflexive shift of attention in response to auditory judgment. Participants fixated on a schematic face in which the eyes looked left or right (the cue). A target sound was then presented to the left or right of the cue. Participants judged the direction of the target as quickly as possible. Even though participants were told that the gaze direction did not predict the direction of the target, the response time was significantly faster when the gaze was in the target direction than when it was in the non‐target direction. These findings provide initial evidence for visual‐upon‐auditory spatial‐cuing effects produced by centrally presented cues, suggesting that a reflexive crossmodal shift of attention does occur with a centrally presented visual stimulus.     

What do graded effects of semantic transparency reveal about morphological processing?

We examined the influence of semantic transparency on morphological facilitation in English in three lexical decision experiments. Decision latencies to visual targets (e.g., CASUALNESS) were faster after semantically transparent (e.g., CASUALLY) than semantically opaque (e.g., CASUALTY) primes whether primes were auditory and presented immediately before onset of the target (Experiment 1a) or visual with an stimulus onset asynchrony (SOA) of 250 ms (Experiment 1b). Latencies did not differ at an SOA of 48 ms (Experiment 2) or with a forward mask at an SOA of 83 ms (Experiment 3). Generally, effects of semantic transparency among morphological relatives were evident at long but not at short SOAs with visual targets, regardless of prime modality. Moreover, the difference in facilitation after opaque and transparent primes was graded and increased with family size of the base morpheme.     

Prediction during language processing is a piece of cake-But only for skilled producers

Are there individual differences in children's prediction of upcoming linguistic input and what do these differences reflect? Using a variant of the preferential looking paradigm (Golinkoff, Hirsh-Pasek, Cauley, & Gordon, 1987), we found that, upon hearing a sentence like, "The boy eats a big cake," 2-year-olds fixate edible objects in a visual scene (a cake) soon after they hear the semantically constraining verb eats and prior to hearing the word cake. Importantly, children's prediction skills were significantly correlated with their productive vocabulary size-skilled producers (i.e., children with large production vocabularies) showed evidence of predicting upcoming linguistic input, while low producers did not. Furthermore, we found that children's prediction ability is tied specifically to their production skills and not to their comprehension skills. Prediction is really a piece of cake, but only for skilled producers. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Audiovisual integration in noise by children and adults

The aim of this study was to investigate the development of multisensory facilitation in primary school-age children under conditions of auditory noise. Motor reaction times and accuracy were recorded from 8-year-olds, 10-year-olds, and adults during auditory, visual, and audiovisual detection tasks. Auditory signal-to-noise ratios (SNRs) of 30-, 22-, 12-, and 9-dB across the different age groups were compared. Multisensory facilitation was greater in adults than in children, although performance for all age groups was affected by the presence of background noise. It is posited that changes in multisensory facilitation with increased auditory noise may be due to changes in attention bias.     

The ventriloquist effect does not depend on the direction of deliberate visual attention

It is well known that discrepancies in the location of synchronized auditory and visual events can lead to mislocalizations of the auditory source, so-called ventriloquism. In two experiments, we tested whether such cross-modal influences on auditory localization depend on deliberate visual attention to the biasing visual event. In Experiment 1, subjects pointed to the apparent source of sounds in the presence or absence of a synchronous peripheral flash. They also monitored for target visual events, either at the location of the peripheral flash or in a central location. Auditory localization was attracted toward the synchronous peripheral flash, but this was unaffected by where deliberate visual attention was directed in the monitoring task. In Experiment 2, bilateral flashes were presented in synchrony with each sound, to provide competing visual attractors. When these visual events were equally salient on the two sides, auditory localization was unaffected by which side subjects monitored for visual targets. When one flash was larger than the other, auditory localization was slightly but reliably attracted toward it, but again regardless of where visual monitoring was required. We conclude that ventriloquism largely reflects automatic sensory interactions, with little or no role for deliberate spatial attention.     

Modality effects and the structure of short-term verbal memory

The effects of auditory and visual presentation upon short-term retention of verbal stimuli are reviewed, and a model of the structure of short-term memory is presented. The main assumption of the model is that verbal information presented to the auditory and visual modalities is processed in separate streams that have different properties and capabilities. Auditory items are automatically encoded in both the A (acoustic) code, which, in the absence of subsequent input, can be maintained for some time without deliberate allocation of attention, and a P (phonological) code. Visual items are retained in both the P code and a visual code. Within the auditory stream, successive items are strongly associated; in contrast, in the visual modality, it is simultaneously presented items that are strongly associated. These assumptions about the structure of short-term verbal memory are shown to account for many of the observed effect of presentation modality.     

The contribution of rapid visual and auditory processing to the reading of irregular words and pseudowords presented singly and in contiguity

This study examined the relative involvement of rapid auditory and visual temporal resolution mechanisms in the reading of phonologically regular pseudowords and English irregular words presented both in isolation and in contiguity as a series of six words. Seventy-nine undergraduates participated in a range of reading, visual temporal, and auditory temporal tasks. The correlation analyses suggested a general timing mechanism across modalities. There were more significant correlations between the visual temporal measures and irregular word reading and between the auditory measures and pseudoword reading. Auditory gap detection predicted pseudoword reading accuracies. The low temporal frequency flicker contrast sensitivity measure predicted the accuracies of isolated irregular words and pseudowords presented in contiguity. However, when a combined speed-accuracy score was used, visible persistence at both low and high spatial frequencies and auditory gap detection were active in the reading of pseudowords presented in contiguity. Sensory processing skills in both visual and auditory modalities accounted for some of the variance in the reading performance of normal undergraduates, not just reading-impaired students.     

Comprehension of televised stories by preschool children with ADHD.

Investigated visual attention to and story comprehension of televised stories in 4- to 6-year-old children with attention deficit hyperactivity disorder (ADHD) and comparison children. Half of the children in each group watched the program with toys in the room, and the other half watched without toys. Visual attention to the television was recorded, and story comprehension was assessed by performance on cued recall questions. All children attended significantly less when toys were present, but the difference when toys were present was greater for children with ADHD. The groups did not differ on recall of factual information when toys were absent. When toys were present, the comparison children showed no decrement in performance on factual questions, whereas the performance of children with ADHD was significantly worse. On questions testing causal connections, the children with ADHD performed more poorly than comparison children regardless of whether toys were present. Implications of these results for understanding and treating the academic and social difficulties of children with ADHD are discussed.     

Effects of Test Order and Modality on Sustained Attention in Children With Epilepsy

Neurological conditions affect sustained attention, but the effects of modality and interactions with test order have not been examined. In a 2?×?2 (Order?×?Modality) design using 54 children with chronic epilepsy, performance was compared on an auditory measure (modified Seashore Rhythm Test) versus a visual measure of attention (modified Conners’ Continuous Performance Test). Auditory scores were worse than visual, F(1,?52)?=?98.93, p<.001, but there was no order effect or interaction (p>.05). Implications for assessment and intervention are discussed.     

Generating inferences from written and spoken language: A comparison of children with visual impairment and children with sight

The two experiments reported here investigated the ability of sighted children and children with visual impairment to comprehend text and, in particular, to draw inferences both while reading and while listening. Children were assigned into ‘comprehension skill’ groups, depending on the degree to which their reading comprehension skill was in line with that predicted by their decoding skill. They then read (either print or Braille) and listened to a series of novel short stories. These were followed by a series of questions, which required either the generation of inferences, or an answer that could be taken literally from the text. The results suggest that children with and without sight are comparable in their ability to draw inferences, and that children with visual impairment show an advantage for literal questions under auditory presentation.
