Anger communication in deaf children

In this study, we investigated how deaf children express their anger towards peers and with what intentions. Eleven-year-old deaf children (n=21) and a hearing control group (n=36) were offered four vignettes describing anger-evoking conflict situations with peers. Children were asked how they would respond, how the responsible peer would react, and what would happen to their relationship. Deaf children employed the communicative function of anger expression differently from hearing children. Whereas hearing children used anger expression to reflect on the anguish that another child caused them, deaf children used it rather bluntly and explained less. Moreover, deaf children expected less empathic responses from the peer causing them harm. Both groups did, however, expect equally often that the relationship with the peer would stay intact. These findings are discussed in the light of deaf children's impaired emotion socialization secondary to their limited communication skills.     

Juvenile psychopathy and judicial decision making: an empirical analysis of an ethical dilemma

In the burgeoning juvenile psychopathy literature, there is a debate on whether it is appropriate to apply this construct to youths. Some have suggested that labeling children/adolescents as psychopathic might result in negative consequences, such as being recommended for more restrictive placements. However, the scant evidence is equivocal. This study provides additional insights on this issue by assessing judicial perceptions and recommendations to a hypothetical case. Results indicate that psychopathy influenced perceptions of amenability (eta = .12) and dangerousness (eta = .25), and recommendations for placement (eta = .11). More specifically, youth who were both labeled as psychopathic and ascribed psychopathic traits were viewed as less amenable to treatment and more dangerous and were more likely to be recommended for a restrictive placement than youth who were neither labeled nor described as such. The effect of psychopathy on placement recommendations, however, was not significant after controlling for perceptions of dangerous. This suggests that the influence of psychopathy on judicial restrictiveness may operate through the perceived dangerousness of the youth.     

Comparison of balance and gait in visually or hearing impaired children

The study was planned to evaluate the effect of loss of hearing and vision on balance and gait in 60 children, 20 of whom had hearing loss (M age = 9.3 yr., SD = 0.9), 20 who were visually impaired (M age = 12.2 yr., SD = 2.5), and 20 controls with no disability (M age = 9.4 yr., SD = 0.6). Standing Balance subtests of the Southern California Sensory Integration Tests were used. Gait analysis was conducted on a powdered surface. When the gait analysis results of the three groups of children were compared, statistically significant differences were noted. Scores for the hearing impaired group were more like those of the control group than those of the visually impaired group. Results show that children with visual impairment had more problems with balance and gait than controls.     

From fancy to reason: Scaling deaf and hearing children's understanding of theory of mind and pretence

We examined deaf and hearing children's progression of steps in theory of mind (ToM) development including their understanding of social pretending. Ninety‐three children (33 deaf; 60 hearing) aged 3–13 years were tested on a set of six closely matched ToM tasks. Results showed that deaf children were delayed substantially behind hearing children in understanding pretending, false belief (FB) and other ToM concepts, in line with their delayed uptake of social pretend (SP) play. By using a scaling methodology, we confirmed previous evidence of a consistent five‐step developmental progression for both groups. Moreover, by including social pretence understanding, both deaf and hearing children's ToM sequences were shown to extend reliably to six sequential developmental steps. Finally and focally, even though both groups' sequences were six steps long, the placement of pretence relative to other ToM milestones varied with hearing status. Deaf children understood social pretending at an earlier step in the ToM sequence than hearing children, albeit at a later chronological age. Theoretically, the findings are relevant to questions about how universal developmental progressions come together along with culturally distinctive inputs and biological factors (such as hearing loss) to set the pace for ToM development.     

Children's consumption behavior in response to food product placements in movies

Almost all research on the effects of product placements on children has focused on brand attitudes or behavioral intentions. Drawing on the important difference between attitudes or behavioral intentions on the one hand and actual behavior on the other, this paper tests the effects of brand placements on children's food consumption. Children from 6 to 14 years old were exposed to an excerpt of the popular movie Alvin and the Chipmunks, including placements for the product Cheese Balls. Three versions were created: one without placements, one with moderate placement frequency, and one with high placement frequency. Results showed that exposure to high‐frequency product placements exerted a significant effect on snack consumption, but no effect on brand or product attitudes. These effects were independent of children's ages. The findings are of great importance to consumer behavior scholars, nutrition experts, and policy regulators.

The Role of Placement History and Current Family Environment in Children’s Aggression in Foster Care

Predictors of the physical and relational aggressive behavior of children in foster care were examined (N?=?160, 50.9% male, M age?=?7.57, SD?=?2.39). First, predictors representative of children’s placement histories were examined in relation to the children’s aggression at T1. Next, predictors representing characteristics of the current family environment were examined in relation to the children’s aggression at T2 (4 months later). Results revealed that a greater number of prior group home placements and being in a non-kinship home were associated with higher physical aggression at T1. A greater number of prior group home placements, a fewer number of regular home placements, being in a non-kinship home, and prior removal from the home due to neglect were associated with higher relational aggression at T1. The results also revealed that higher foster sibling relational aggression at T1 predicted lower child physical aggression at T2. If foster siblings were biological children of the foster parent, higher levels of a foster sibling’s physical aggression at T1 predicted reduced child physical aggression at T2. The opposite pattern was observed if foster siblings were not biological children of the foster parent. Lastly, longer time in the current placement, more children in the home, and the presence of a sibling that was a biological child of the parent predicted higher child relational aggression at T2. These findings provide initial insights into how placement history and current family environment are associated with the physical and relational aggressive behavior of children in foster care.

The effect of a simulated hearing loss on performance of an auditory memory task in driving

Hearing loss has been shown to exacerbate the effect of auditory distraction on driving performance in older drivers. This study controlled for the potentially confounding factor of age-related cognitive decrements, by applying a simulated hearing loss in young, normally hearing individuals. Participants drove a simulated road whilst completing auditory tasks under simulated hearing loss or normal hearing conditions. Measures of vehicle control, eye movements and auditory task performance were recorded. Results showed that performing the auditory tasks whilst driving resulted in more stable lateral vehicle control and a reduction in gaze dispersion around the road centre. These trends were not exacerbated by simulated hearing loss, suggesting no effect of hearing loss on vehicle control or eye movement patterns during auditory task engagement. However, a small effect of simulated hearing loss on the performance of the most complex auditory task was observed during driving, suggesting that the use of sound-based in-vehicle systems may be problematic for hearing impaired individuals. Further research incorporating a wider variety of driving scenarios and auditory tasks is required in order to confirm the findings of this study.     

Developmental differences in memory for cross‐modal associations

Associative learning is critical to normal cognitive development in children. However, young adults typically outperform children on paired‐associate tasks involving visual, verbal and spatial location stimuli. The present experiment investigated cross‐modal odour–place associative memory in children (7–10 years) and young adults (18–24 years). During the study phase, six odours were individually presented and paired with one of 12 spatial locations on a board. During the test phase, participants were presented with the six stimuli individually and were asked to place each stimulus on the correct spatial location. Children committed significantly more errors on the odour–place task than did young adults. However, item recognition memory for the odours or spatial locations involved in the odour–place associative memory task was similar between children and young adults. Therefore, poor odour–place associative memory in children did not result from impaired memory for the individual odours or spatial locations involved in the associations. The results suggest that cross‐modal associative memory is not fully developed in children.     

Cognitive consequences of congenital deafness

Comparing congenitally deaf children with hearing children on a variety of information processing tasks provides a natural test of the developmental consequences accompanying the long term loss of a particular sensory input. In this experiment, two sequential and two spatial tasks were used to evaluate the way deaf and hearing individuals process these different types of information. When deaf students were asked to recall the order of a string of lights, they performed as well as hearing students. Deaf students were at a significant disadvantage, however, when processing sequentially presented digits. Deaf students performed as well as hearing students on two complex, standardized spatial tasks. The loss of a major sensory modality had minimal effect on three of the four tasks investigated in the present study. Explanations for the single task with a performance differential are considered.

Developmental Changes in Young Children's Spatial Memory and Language in Relation to Landmarks

Two experiments investigated how young children and adults understand whether objects are by a landmark and remember their locations. Three- and 4-year-old children and adults were asked to judge whether several blocks were by a landmark. The blocks were arranged so that their absolute and relative distances from the landmark varied. Later, the blocks were removed, and participants were asked to place them in their original locations. All ages relied on relative distance between objects and a landmark when making by judgments; however, older children and adults showed systematic judgments. Relative distance also affected block placement, and systematicity increased across development. Children's understanding of the relative nature of by and their ability to remember locations precisely increased during the preschool years, indicating developmental changes in the adaptive combination of location cues for spatial language and memory.

Auditory perception of speech and speech sounds in recent and recovered cases of aphasia

Auditory perception of speech and speech sounds was examined in three groups of patients with cerebral damage in the dominant hemisphere. Two groups consisted of brain-injured war veterans, one group of patients with high-frequency hearing loss and the other, a group of patients with a flat hearing loss. The third group consisted of patients with recent cerebral infarcts due to vascular occlusion of the middle cerebral and internal carotid artery. Word and phoneme discrimination as well as phoneme confusions in incorrect responses were analyzed from conventional speech audiometry tests with bisyllabic Finnish words fed close to the speech reception threshold of the patient. The results were compared with those of a control group with no cerebral disorders and normal hearing. The speech discrimination scores of veterans with high-frequency hearing loss and patients with recent cerebral infarcts were some 15–20% lower than those of controls or veterans with flat hearing loss. Speech sound feature discrimination, analyzed in terms of place of articulation and distinctive features, was distorted especially in cases of recent cerebral infarcts, whereas general information transmission of phonemes was more impaired in patients with high-frequency hearing loss.     

Factor analysis and discriminant analysis of psychoeducational report contents

This study evaluated the psychoeducational reports of 205 children who were referred to the UCLA Neuropsychiatric Hospital for evaluation of academic achievement problems. Factor analysis of the report data indentified a medical factor, a school history factor, and a family factor. Following factor analysis, all three factors as well as measures of cognitive functioning and academic achievement were entered into a discriminant analysis in order to determine which variables, if any, helped predict the educational placement finally to be recommended for each child at the end of the individual psychoeducational work-up. Statistical analysis indicated different results for each of four educational placement options, the greatest predictability being associated with regular classroom placement. Across all placements, the variable that allowed for the greatest accuracy in predicting educational programming recommendations was academic achievement, measured as mean achievement score on standardized achievement tests.     

Effects of language experience on the perception of American Sign Language

Perception of American Sign Language (ASL) handshape and place of articulation parameters was investigated in three groups of signers: deaf native signers, deaf non-native signers who acquired ASL between the ages of 10 and 18, and hearing non-native signers who acquired ASL as a second language between the ages of 10 and 26. Participants were asked to identify and discriminate dynamic synthetic signs on forced choice identification and similarity judgement tasks. No differences were found in identification performance, but there were effects of language experience on discrimination of the handshape stimuli. Participants were significantly less likely to discriminate handshape stimuli drawn from the region of the category prototype than stimuli that were peripheral to the category or that straddled a category boundary. This pattern was significant for both groups of deaf signers, but was more pronounced for the native signers. The hearing L2 signers exhibited a similar pattern of discrimination, but results did not reach significance. An effect of category structure on the discrimination of place of articulation stimuli was also found, but it did not interact with language background. We conclude that early experience with a signed language magnifies the influence of category prototypes on the perceptual processing of handshape primes, leading to differences in the distribution of attentional resources between native and non-native signers during language comprehension.     

Sad and happy emotion discrimination in music by children with cochlear implants

Children using cochlear implants (CIs) develop speech perception but have difficulty perceiving complex acoustic signals. Mode and tempo are the two components used to recognize emotion in music. Based on CI limitations, we hypothesized children using CIs would have impaired perception of mode cues relative to their normal hearing peers and would rely more heavily on tempo cues to distinguish happy from sad music. Study participants were children with 13 right CIs and 3 left CIs (M = 12.7, SD = 2.6 years) and 16 normal hearing peers. Participants judged 96 brief piano excerpts from the classical genre as happy or sad in a forced-choice task. Music was randomly presented with alterations of transposed mode, tempo, or both. When music was presented in original form, children using CIs discriminated between happy and sad music with accuracy well above chance levels (87.5%) but significantly below those with normal hearing (98%). The CI group primarily used tempo cues, whereas normal hearing children relied more on mode cues. Transposing both mode and tempo cues in the same musical excerpt obliterated cues to emotion for both groups. Children using CIs showed significantly slower response times across all conditions. Children using CIs use tempo cues to discriminate happy versus sad music reflecting a very different hearing strategy than their normal hearing peers. Slower reaction times by children using CIs indicate that they found the task more difficult and support the possibility that they require different strategies to process emotion in music than normal.     

Suggestibility and source monitoring errors: blame the interview style,interviewer consistency,and the child's personality

Sixty children were forced to confabulate or given misinformation about a simulated crime. Higher suggestibility in the forced confabulation group than in the suggestive group occurred even after 1 week. Interview source errors in the forced confabulation group were higher for confabulations when asked by the same person, but for control items when asked by a different person. Interview source errors in the suggestive group were higher for confabulations when asked by a different person, but for control items when asked by the same person. Confabulations were misattributed to the video by the forced confabulation more than the suggestive group. However, both groups mistakenly believed they had previously discussed control true‐event items. Suggestibility was high when imaginative and dissociative children were forced to confabulate. Control false‐event items were misattributed to the interview by compliant children and to the video by imaginative children in the forced confabulation group. Shy children in the forced confabulation group misattributed confabulations to the video, whereas distractible children in the suggestive group misattributed control false‐event items to both sources.
