Speaker identification is a challenge for cochlear implant users because their prosthesis restricts access to the cues that underlie natural voice quality. The present thesis examined speaker recognition in the context of spectrally degraded sentences. The listeners of interest were child implant users who were prelingually deaf as well as hearing children and adults who listened to speech via vocoder simulations of implant processing. Study 1 focused on child implant users' identification of a highly salient speaker—the mother (identified as mother)—and unfamiliar speakers varying in age and gender (identified as man, woman, or girl). In a further experiment, children were required to differentiate their mother's voice from the voices of unfamiliar women. Young hearing children were tested on the same tasks and stimuli. Although child implant users performed more poorly than hearing children overall, they successfully differentiated their mother's voice from other voices. In fact, their performance surpassed expectations based on previous studies of child and adult implant users. Even when natural variations in speaking style were reduced, child implant users successfully identified the speakers. The findings imply that person-specific differences in articulatory style contributed to implanted children's successful performance. Study 2 used vocoder simulations of cochlear implant processing to vary the spectral content of sentences produced by the man, woman, and girl from Study 1. The ability of children (5-7 years and 10-12 years) and adults with normal hearing to identify the speakers was affected by the level of spectral degradation and by the gender of the speaker. Female voices were more difficult to identify than was the man's voice, especially for the younger children. In some respects, hearing individuals' identification of degraded voices was poorer than that of child implant users in Study 1. In a further experiment, hearing children and adults were required to provide verbatim repetitions of spectrally degraded sentences. Their performance on this task greatly exceeded their performance on speaker identification at comparable levels of spectral degradation. The present findings underline the importance of ecologically valid materials and methods when assessing speaker identification, especially in children. Moreover, they raise questions about the efficacy of vocoder models for the study of speaker identification in cochlear implant users.

Dimensional models of personality pathology present a promising approach to the assessment of maladaptive personality in adults and children (eg. De Clercq, De Fruyt, & Widiger, 2009). In addition, recent findings show that some childhood maladaptive traits can be predictive of adulthood personality disorders (eg. Mervielde, De Clercq, De Fruyt, & Van Leeuwen, 2005). The Dimensional Personality Symptom Item Pool (DIPSI) is a questionnaire designed to measure maladaptive lower and higher order traits in children and adolescents. This study aims to examine the DIPSI’s scales and to replicate several previous findings of maladaptive trait patterns in children. The results indicate that the DIPSI’s lower and higher order trait scales are high in reliability and show many of the trait relationships suggested by previous literature. A successful outcome of this study serves as the first step towards establishing the DIPSI as a valid and useful measure of personality pathology in children.

This thesis evaluates the effectiveness of study components in order to aid in design refinements for a larger randomized controlled trial (RCT). A total of 38 post-secondary students with Attention-Deficit/Hyperactivity Disorder (ADHD) were randomized into a waitlist control group, or standard-length (45 minute) or shortened-length (15 minute) WM training group. Criterion measures included the WAIS-IV Digit Span (auditory-verbal WM), CANTAB Spatial Span (visual-spatial WM) and WRAML Finger Windows (visual-spatial WM). Transfer-of-training effects were assessed using indices of everyday cognitive functioning. Participants in the standard- and shortened-length groups showed greater improvements at post-test on auditory-verbal WM and reported fewer cognitive failures in everyday life than waitlist controls. Participants in the standard-length group showed greater improvements in visual-spatial WM at post-test than participants in the other two groups. Preliminary findings suggest that shorter training may have similar beneficial outcomes as documented for the standard-length training, indicating that a larger-scale RCT is warranted.

The goals of the present study were: 1) to describe and provide initial support for the validity of the Future Scenarios Questionnaire (FSQ), a new self-report questionnaire designed to measure parental responding to anticipated children’s negative emotions; and 2) to examine how maternal responses on the FSQ related to young children’s aggressive, asocial, and prosocial behaviors with peers. Further, this study examined whether the temperamental trait of negative affect moderated the relation between maternal responses on the FSQ and children’s social adjustment outcomes. Participants were 92 mothers of preschool-age children (43 boys and 49 girls; M age 61.5 months). Mothers provided ratings on the FSQ and child temperament ratings on the Child Behavior Questionnaire (CBQ; Rothbart, Ahadi, & Hershey, 1994). They also completed a range of measures which were included to assess the construct validity of the FSQ. These included measures of attachment representations, maternal mind-mindedness, perceived control, and alexithymia. Sixty-nine teachers provided ratings on the Child Behavior Scale (CBS; Ladd & Profilet, 1996) for children’s aggressive, asocial, and prosocial behaviors in the peer context. Factor analysis of the FSQ revealed two subscales: Encourage Emotion Expression (EEE) and Discourage Emotion Expression (DEE). Patterns of correlations among these subscales and the additional mother measures suggested that the FSQ demonstrates some construct validity. Further, the results of the moderation analyses showed that maternal responding on the FSQ interacts with negative affect in the prediction of child behaviors, however not in the hypothesized ways. In particular, encouraging emotion expression significantly predicted more asocial behavior and less prosocial behavior (approached significance), but only for children rated high in negative affect. Similarly, discouraging emotion expression significantly predicted less aggressive behavior only for high negative affect children. None of these relations was significant for children rated low in negative affect. The theoretical and practical implications of these findings are discussed in terms of the importance of considering child temperament in emotion socialization processes.

One hundred and eleven mother-child dyads visited the laboratory when children were 10 to 12 years old and again two years later. Children’s self-disclosure to mothers and mothers’ accurate knowledge of effective comforting strategies were examined together in the context of maternal warmth and children’s positive coping. Maternal warmth longitudinally predicted children’s disclosure, and children’s disclosure longitudinally predicted mothers’ accurate knowledge of comforting strategies. Maternal warmth moderated the association between mothers’ accurate knowledge of comforting strategies and children’s positive coping. Specifically, maternal knowledge predicted child coping only in children of cold mothers. Implications for the socialization of coping and the role of child disclosure and parents’ accurate knowledge in parenting interventions are discussed.

This study examined links between antisocial behaviour, moral emotions (i.e., sympathy and guilt), and negative emotionality in an ethnically diverse sample of 4- and 8-year-old children (N = 79). Primary caregivers reported their children’s antisocial behaviour, sympathy, and negative emotionality through a questionnaire and across a 10-day span via daily diary entries (n = 474 records). In a semi-structured interview, children reported their sympathy levels and guilt feelings. Children with high guilt in harm contexts and low negative emotionality were rated as less antisocial in both questionnaire and diary reports. For children with low guilt in exclusion contexts, low sympathy ratings predicted higher questionnaire-reported antisocial behaviour. For children with high guilt in prosocial omission contexts, high sympathy ratings predicted lower diary-reported antisocial behaviour. Lastly, high sympathy ratings predicted lower questionnaire-reported antisocial behaviour for children with low negative emotionality.

This study examined self-reported emotions and emotional facial expressions following moral transgressions using an ethnically diverse sample of 242 4-, 8-, and 12-year-old children. Self-reported emotions were examined in response to three transgression contexts: an intentional harm, an instance of social exclusion, and an omission of a prosocial duty. Children’s emotional expressions of sadness, happiness, anger, fear and disgust were analyzed immediately after being asked how they would feel if they had committed one of the described transgressions. Emotional expressions were scored using automated emotion recognition software. Four-year-olds reported significantly more happiness as compared to 8- and 12-year-olds. In addition, self-reports of sadness decreased between 8- and 12-year-olds, while self-reported guilt increased between these age groups. Furthermore, 4- and 8-year-olds demonstrated higher levels of facially expressed happiness than 12-year-olds. These findings highlight the role of automatic affective and controlled cognitive processes in the development of children’s emotions following moral transgressions.

This study explored the effectiveness of Handle With Care, a mental health promotion training program for child care practitioners working with children between birth to age 6. Handle With Care program content is based on research evidence. Training units are intended to deepen practitioners’ understanding of how children’s social-emotional development, centre and family connections and positive workplace activities link to children’s well-being and practitioners’ roles in these areas. Fifty-seven front-line practitioners from three different regional groups (Rural, Suburban, Urban) completed Handle With Care workshops and were compared to 56 comparison participants, matched according to region, who were not exposed to training. The evaluation utilized a time series repeated measures design and consisted of mixed quantitative and qualitative measures to determine training outcomes related to practitioner’s mental health promotion knowledge and practices. Findings indicated that child care practitioners who participated in Handle With Care training demonstrated increased mental health promotion knowledge. In particular, they acquired better comprehension of issues concerning practitioner and child attachment relationships, children’s self-esteem, emotion expression and regulation and peer relationships. Training participants significantly differed from comparison participants in their knowledge of these topics. In terms of practices, training participants also evidenced significantly improved practices relative to comparison participants. These gains were especially observed in relation to practitioners building trusting relationships with children, fostering children’s sense of self and competence, positive peer interactions and practitioners promoting their own mental health. In contrast, Handle With Care training did not show the intended consistent outcomes with respect to practitioners helping children with emotional communication, dealing with diversity, changes and transitions and practitioners building relationships with children’s parents. Results tended to be discrepant across regional groups, and in some instances, gains in mental health promotion and knowledge were not sustained over time. Overall, the study suggests that Handle With Care is a useful way to augment child care practitioners’ capacity to consider the mental health of all children in their care and flexibly implement strategies to help children reach their optimal potential. The study also provides important information concerning regional differences and areas of training content that may benefit from revision.

Psychologists have proposed that schools should teach for wisdom, but this proposal has rarely been investigated. The present study examines secondary school English language arts as a site of wisdom learning. This qualitative study investigates the instructional goals and beliefs of 16 secondary English teachers (8 beginner, 8 experienced). Interviews were analysed using techniques based in Interpretative Phenomenological Analysis. Results are discussed in light of psychological research, studies of English teaching, and the Ontario curriculum. Some elements of wisdom teaching appear to be supported in English education. Teachers connected literature teaching and classroom practices to students' life learning, emphasizing life themes, connections to self and experience, self-reflective learning, and individual needs. Experienced teachers frequently made direct connections between life/wisdom learning and student engagement, while beginners voiced concerns about negotiating supportive student- teacher relationships. Implications for proposals to teach for wisdom in schools are discussed, including a possible role for critical literacy.

On évoque souvent des difficultés à interagir socialement chez les enfants ayant une dysphasie. Ces difficultés sont généralement attribuées aux troubles du langage, mais elles pourraient aussi provenir d’un problème à décoder les émotions des autres. Le but de la présente recherche est d’explorer cette voie chez les enfants dysphasiques de 9 à 12 ans. Différents stimuli émotionnels leur ont été présentés sous forme de vidéos ainsi qu’à des enfants d’un groupe contrôle selon cinq conditions : parole non filtrée, parole filtrée, visage dynamique, visage dynamique accompagné de la parole non filtrée, et visage dynamique avec parole filtrée. Les enfants dysphasiques et les enfants du groupe contrôle ne se comportent pas différemment de manière significative en fonction des émotions présentées et des conditions testées. Par contre, un sous-groupe d’enfants ayant une dysphasie mixte commet significativement plus d’erreurs pour l’ensemble de la tâche que le sous-groupe d’enfants sans dysphasie de même âge chronologique. En fait une part seulement des enfants dysphasiques mixtes ont des scores plus faibles. Ces mêmes enfants présentent un QI non verbal faible tandis que leur compréhension du langage est équivalente à celle de leur sous-groupe (enfants dysphasiques mixtes). Malgré ces différences significatives, les scores des enfants dysphasiques mixtes restent relativement élevés et les difficultés observées sont subtiles. Sur le plan clinique, les praticiens (orthophonistes, psychologues, éducateur) devront systématiser l’évaluation des habiletés de décodage des émotions chez l’enfant dysphasique dont les difficultés ne sont pas forcément évidentes dans la vie quotidienne. La recherche devra développer un outil de dépistage sensible aux troubles de décodage émotionnel et des stratégies thérapeutiques adaptées. / Children with Specific Language Impairment (SLI) can have social problems that are often explained by their language disorders. However, the ability to identify other people’s emotions could be caused by their emotion processing difficulties. We explore this question in children with SLI aged 9 to 12 years old. Children with and without SLI were tested on five emotional stimuli presented in dynamic video and audio format: unfiltered speech, filtered speech, facial expressions, facial expressions with unfiltered speech, and facial expressions with filtered speech. The children with impaired language do not differ significantly from the unimpaired children across all modalities and emotions. However, a subgroup of SLI children with mixed (expressive-receptive) delay commits more errors on the task than their age-matched peers. In fact only a subgroup of these children shows lower scores. These same children also show low IQ scores but language comprehension as good as their subgroup. Despite these significant differences the mixed SLI group’s scores are quite high, showing that deficits are subtle. Clinical implications of this study militate for a systematization of the evaluation by health practitioners of these abilities in children with SLI who might not show obvious signs of deficits in this domain in their everyday activities. Research should pursue the development of a sensitive evaluation tool to identify emotional decoding difficulties and should evaluate therapeutic strategies adapted to this population.
