Item Open Access An Investigation of the relationship between motor deficits and academic performance(1990) Dewey, Deborah Maryanne; Kaplan, Bonnie J.Item Open Access Attachment and attributional styles in men and women with symptoms of attention-deficit/hyperactivity disorder(2003) Brown, Deborah L.; Kaplan, Bonnie J.Development of the auditory system can be investigated by using the cochlear traveling wave delay. Auditory brainstem response (ABR) and otoacoustic emissions (OAE) have been used to estimate this delay in order to' study the frequency dependent maturation of cochlear function in humans. Distortion Product Emissions (OPE) are a type of OAE. The OPE, unlike ABR, is a pre-neural measurement that does not include any synaptic component. Mean group delays can be estimated from the OPE phase-versusfrequency relationship (Kimberley et al., 1993). The present investigation used DPEs to estimate the round-trip travel time from 1.7 to IO kHz from 3 groups of neonates: 30-33 , 34-37, and 38-42 wks. conceptional age (CA); and an adult group. The results were consistent with the results from Kimberley et al. (1993) who found that as frequency increased round-trip travel time decreased. However, travel times in the youngest age group (30-33 wks. CA) were longer than for the older two infant groups (34-37 & 38-42 wks. CA). This difference may be attributable to changes or development in the middle ear. No significant differences in travel times were found between the 34-37 week CA infants and those of 38-42 week CA suggesting that some maturation is occurring up until 34 weeks CA. In comparison with the adults, the travel times from the two older newborn groups were not significantly different for either the high (7 & IO kHz) or low ( 1.7 & 2.4 kHz) f 2 frequencies, however in the mid-frequency range (3.5 & 5 kHz) the travel times were shorter in newborns. This difference in the mid-frequency range may be attributable to standing waves in the ear canal in the adults which could decrease the intensity of the primary tones used and therefore increase the latency of the travel time in that range (Dreisbach & Siegel, 1995). The similarities in the travel times at the high and low f2 frequencies suggest that the cochlea is adult-like by 34 weeks CA. This differs from the results of previous ABR studies which found that adult values were not reached until 3-6 months of age.Item Open Access Attributional styles and psychopathology in women identified in adulthood with attention-deficit/hyperactivity disorder(1997) Rucklidge, Julia Jane; Kaplan, Bonnie J.Item Open Access Cognitive and behavioural function in children of mothers with immunological disorders(1996) Glogauer, Maline Eleanor; Kaplan, Bonnie J.Item Open Access Comorbidity of attention-deficit/hyperactivity disorder and internalizing symptoms(2000) Galbraith, Kim M.; Kaplan, Bonnie J.Item Open Access Comparison of sample characteristics in two pregnancy cohorts: community-based versus population-based recruitment methods(BioMed Central, 2013-12-06) Leung, Brenda; McDonald, Sheila W.; Kaplan, Bonnie J.; Giesbrecht, Gerald F.; Tough, Suzanne C.Item Open Access Developmental differences between same-sex and opposite-sex twins(1995) Rucklidge, Julia Jane; Kaplan, Bonnie J.Item Open Access Differences in adult ADHD subtypes based on comorbidities and attention processes(2001) Dye, Bradley George; Kaplan, Bonnie J.Item Open Access Does prenatal micronutrient supplementation improve children’s mental development? A systematic review(BioMed Central, 2011-02-03) Leung, Brenda M. Y.; Wiens, Kristin P.; Kaplan, Bonnie J.Item Open Access Familial patterns of reading disabilities classified by presence or absence of motor problems(1987) Regehr, Sonya M.; Kaplan, Bonnie J.Item Open Access Intergenerational transmission of adverse childhood experiences via maternal depression and anxiety and moderation by child sex(2018-07-23) Letourneau, Nicole Lyn; Dewey, Deborah; Kaplan, Bonnie J.; Ntanda, Henry N.; Novick, Jason; Thomas, Jenna C.; Deane, Andrea J.; Leung, Brenda My; Pon, Kylie; Giesbrecht, G. F.; APrON Study TeamAdverse childhood experiences (ACEs) of parents are associated with a variety of negative health outcomes in offspring. Little is known about the mechanisms by which ACEs are transmitted to the next generation. Given that maternal depression and anxiety are related to ACEs and negatively affect children's behaviour, these exposures may be pathways between maternal ACEs and child psychopathology. Child sex may modify these associations. Our objectives were to determine: (1) the association between ACEs and children's behaviour, (2) whether maternal symptoms of prenatal and postnatal depression and anxiety mediate the relationship between maternal ACEs and children's behaviour, and (3) whether these relationships are moderated by child sex. Pearson correlations and latent path analyses were undertaken using data from 907 children and their mothers enrolled the Alberta Pregnancy Outcomes and Nutrition study. Overall, maternal ACEs were associated with symptoms of anxiety and depression during the perinatal period, and externalizing problems in children. Furthermore, we observed indirect associations between maternal ACEs and children's internalizing and externalizing problems via maternal anxiety and depression. Sex differences were observed, with boys demonstrating greater vulnerability to the indirect effects of maternal ACEs via both anxiety and depression. Findings suggest that maternal mental health may be a mechanism by which maternal early life adversity is transmitted to children, especially boys. Further research is needed to determine if targeted interventions with women who have both high ACEs and mental health problems can prevent or ameliorate the effects of ACEs on children's behavioural psychopathology.Item Open Access Memory and executive functioning in young women reporting mood symptoms(2003) Galbraith, Kim M.; Kaplan, Bonnie J.Item Open Access Nonverbal cue perception and social competence in children with symptoms of AD/HD(2001) Mansley, Chrystal L.; Kaplan, Bonnie J.Item Open Access Posttraumatic growth in children and adolescents with cancer(2002) Yaskowich, Kyla M.; Kaplan, Bonnie J.; Whitsett, StanItem Open Access Relationships between parental characteristics and perceptions of and emotional responses to child behavior(1998) Kneppers, Kirstie Anna; Kaplan, Bonnie J.Item Open Access Social skills knowledge and performance in children with ADHD: an examination of interfering responses(2004) Banks, Tracy; Kaplan, Bonnie J.Based on the social skills classification system by Gresham (1988, 2001) and the work of Wheeler and Carlson (1994), the present study examined social skills knowledge and performance in children with Attention Deficit Hyperactivity Disorder (ADHD), considering four possible interfering responses (impulsivity, aggression, anxiety/depression, academic achievement). It was hypothesised that anxiety/depression and low academic achievement would be related to social skills knowledge deficits, while aggression and impulsivity would be related to social skills performance deficits. Differences in social skills knowledge and performance between ADHD subtypes were also examined. Participants were 80 children, aged 11 to 14 years, who met criteria for ADHD, and one of their parents. Parents completed the Barkley Clinical Interview for ADHD (Barkley, 1997a) via telephone, and families were visited in their homes for the administration of the Social Skills Rating System (Parent Form; Gresham & Elliott, 1990), a social knowledge interview developed for the present study, the Self-Control Rating Scale (Kendall & Wilcox, 1979), the Child Behavior Checklist (Achenbach, 1991) , and the Wide Range Achievement Test-3. Hypotheses were partially supported. Results of regression analyses indicated that social skills knowledge was predicted by anxiety/depression and academic performance, but not by aggressive behaviour. Social skills performance was predicted by impulsivity, aggressive behaviour, and unexpectedly, anxiety/depression, but not by academic achievement. Children with predominantly inattentive ADHD symptoms (ADHD-I) demonstrated significantly more knowledge of self control and cooperation with respect to social situations than did children with combined ADHD symptoms (ADHD-C). Children with both subtypes demonstrated both strengths and weaknesses in social skills performance. Children with ADHD-C were more assertive than children with ADHD-I, while children with ADHD-I were more cooperative than children with ADHD-C. Clinical implications of these findings were discussed with respect to the development of social skills training programs that are tailored to meet the needs of children with both subtypes of ADHD, and that focus on providing a strong generalisation component to encourage performance of acquired social skills.Item Open Access Subtype and gender differences in attention-deficit/hyperactivity disorder: An investigation of selected neuropsychological variables(1999) Prout, Phyllis Ida; Kaplan, Bonnie J.Item Open Access The impact of attention deficit hyperactivity disorder on the accommodative behaviour of marital partners(1998) Shulman, Ian David; Kaplan, Bonnie J.Item Open Access The impact of relationship factors and anxiety on the maternal childbirth experience(2000) Hill, Todd; Kaplan, Bonnie J.Item Open Access The influence of maternal immunoreactivity on fetal brain development(1994) McAllister, Debbie Lynn; Kaplan, Bonnie J.
