AbstractOral Language and the Approximate Number System – A Preliminary Study Janice Shewen The approximate number system (ANS) involves the processing of rudimentary quantity and is thought to be an innate developmental building block for mathematics and its sister construct, the symbolic system. The conventional belief is that the ANS is language independent; however, this notion is questioned and explored in the current study, which represents a preliminary investigation into the concurrent and longitudinal relations between different aspects of oral language and the ANS in 4-year-old children and one year later when they were 5. A sample of 26 children (13 boys;13 girls) with average intelligence completed standardized measures of oral language and verbal memory, and a computerized quantity discrimination task that required children to accurately discern between two visually presented quantities. Correlational analysis showed concurrent and longitudinal relations between different aspects of language and quantity discrimination. This suggests that different aspects of language predict quantity discrimination over a one-year period and challenge the current and accepted theory that the ANS is a language independent system. The findings also have implications for early childhood education – avenues to strengthen a child's ANS via targeted oral language instruction, curricula, and subsequent provision of experiences. The findings also support early oral language screening to monitor or provide opportunities for improving quantity approximation skills. This early intervention could impact later symbolic processing and mathematic success.

Despite the extensive application of Baumrind's parenting style typology, some argue that it may not adequately capture the implicit warmth Chinese parents embrace. This study attempted to examine whether mind-mindedness could be a key indicator for helping children understand the benevolent intentions behind their mothers' authoritarian parenting practices. Specifically, this study investigated the variations in parenting styles, mind-mindedness, and children's behavior problems in Canada and China, the relationship among these variables, and the moderating effect of mind-mindedness on the relationship between authoritarian parenting and children's behavior problems. Participants were 83 Canadian and 136 Chinese mother-child dyads. Data on parenting styles, mind-mindedness, and problem behaviors were collected from maternal reports and lab observations. As expected, while Chinese mothers exhibited more authoritarian tendencies than Canadian mothers, their mind-mindedness buffer against the negative effect of maternal high-power strategies on children's behavior problems after controlling for maternal age and education. These results provide new perspectives on understanding Chinese parenting.

Researchers have found associations between attachment, childhood adversity, and posttraumatic stress symptoms; however, the underlying mechanisms between these variables remains unknown. The present study explored the moderating effects of childhood adversity on the relationship between adult attachment and posttraumatic stress symptoms in two samples. In total, 533 undergraduate students and 357 individuals recruited from online communities completed measures of childhood adversity, adult attachment, and posttraumatic stress symptoms. Hierarchical regression analyses were used to test the moderating effect on childhood adversity. One-way ANOVA post hoc analyses were run to assess mean differences of attachment and posttraumatic stress across five childhood adversity groups. The results suggested that attachment and childhood adversity do predict posttraumatic stress symptoms; however, there was no significant moderating effect of adversity found. The post hoc analyses revealed significant mean differences for secure attachment, avoidant attachment, and posttraumatic stress symptoms. The findings suggest that attachment and childhood adversity are significantly associated with posttraumatic stress symptoms.

Adolescence is a time when young people focus their attention on setting and pursuing long-term goals. Contemporary approaches of identity development focus on three pivotal processes underlying the identity formation process and the maintenance of one's identity (e.g., core values, etc.). These processes are commitment (commitments to a goal), in-depth exploration (exploration of choices and options), and reconsideration of commitment (feelings of uncertainty about current commitments). The primary purpose of the current study was to examine the relations between identity processes, study habits, and academic performance in 45 female undergraduate students (M age = 21.00). Utilizing a self-report measure, findings suggested a significant positive relation between educational and relational commitment, as well as reconsideration of commitments in the educational domain and reconsideration of commitments in the relational domain. In terms of identity processes and grades, a regression analysis revealed that educational reconsideration of commitments predicted academic performance. Further, for those employing poor study habit skills, educational reconsideration of commitment predicted academic performance. The present study offers insight on the importance of assessing adolescent's uncertainty of educational and relational commitments, while also highlighting the protective factor of maintaining good study habit strategies.

Background: Researchers have provided evidence that attachment may be independently linked to early adversity and criminal behaviour. In this study, I examined the combined associations among these variables in a student and community sample. Method: The first study consisted of undergraduate students (n = 590) who completed surveys to assess early adversity (Felitti, et al., 1988), attachment (Scharfe, 2016), and criminal behaviours. Participants were grouped based on their reports of adverse experiences and engagement in criminal behaviour. The second study was a replication of the first using a community sample (n = 294). Results: My hypotheses were partially supported, and my findings were consistent across Study 1 and Study 2. As I expected, there was a significant main effect for adversity when examining the mean scores of the attachment representations for attachment to mothers (Study 1 F (16, 1763.402) = 3.61, p < .001; Study 2 (F (16, 849.942) = 2.377, p = .002) and attachment to fathers (Study 1 F (16, 1763.402) = 4. 349, p < .001; Study 2 (F (16, 840.776) = 3.067 p < .001)). From examining the means, I concluded that participants who reported greater adversity reported higher insecure-avoidant and lower secure attachment to mothers and fathers. There were no significant main effects for criminal behaviour or significant interaction effects. Impact: To date, no study has explored all three variables explicitly. My findings are able to highlight the critical importance of secure attachment relationships and add further comprehension to exploring factors associated to criminal behaviour.

Early diagnosis of autism spectrum disorder (ASD), while providing many benefits, presents challenges to clinicians such as predicting the stability of symptoms. Accurately predicting symptom severity allows clinicians to confidently diagnose and assign the most appropriate treatment. Little research exists to date to predict symptom severity in children with ASD who have not been exposed to treatment. The present file review examined prelinguistic skills as predictors of symptom severity in a group of young children (age: 18 – 64 months) with ASD (n = 199) who had not been exposed to significant levels of treatment. Hierarchical regression analyses demonstrated that of the two core diagnostic features (social communicative deficits and restricted repetitive behaviours), social communicative skills best predicted symptom severity. Furthermore, social communicative gestures predicted symptom severity after age, adaptive behaviour, restricted repetitive behaviours, and functional gestures had been accounted for.

Recently, a distinction has been made between cognitive theory of mind, the ability to make inferences about other's beliefs and thoughts, and affective theory of mind, the ability to make inferences about other's emotional states. The purpose of this study is to determine if the distinction between cognitive and affective theory of mind is developmentally appropriate and whether the relation between language and theory of mind is maintained when cognitive and affective theory of mind are examined separately. The sample consisted of 20 children aged 6 to 9 years, and 27 children aged 11 to 15 years. Results showed that the older group outperformed the younger group on both cognitive and affective theory of mind, and that different aspects of language were related to each type of theory of mind. This suggests the distinction between cognitive and affective theory of mind may in fact be valid in this age range.

The purpose of this thesis was to explore the role of attachment in university students' help-seeking process using both a cross-sectional and mixed methods study. In the cross-sectional study, I explored whether help-seeking attitudes mediated the relationship between attachment and help-seeking behaviour. As expected, the relationship between secure and preoccupied attachment and greater help-seeking behaviour from both informal and self-help sources was partially mediated by positive attitudes toward seeking non-professional personal help. However, unexpectedly, attitudes toward professional psychological help did not mediate the relationship between attachment and formal help-seeking behaviour. In the mixed-methods study, secure students reported positive help-seeking experiences and discussed facilitators of help-seeking. On the other hand, fearful and dismissing students reported more negative help-seeking experiences and discussed barriers to help-seeking. Discussion of findings focus on how university staff can use attachment theory to develop interventions to increase student help-seeking.

It has been proposed that individuals often form a romantic attachment to their sexual partners. However, there is little understanding of the role of sexual behaviours in an attachment relationship. This study aims to explore the effect of attachment representations on sexual behaviours during foreplay, intercourse, and afterplay. In two studies, individuals (N = 478) and couples (N = 50) completed self-reported measures of attachment, sexual behaviours, and sexual satisfaction. As expected, security predicted various behaviours during each part of a sexual encounter and greater sexual satisfaction. Insecurity (preoccupied, dismissing, and fearful attachment) predicted engagement in post-coital behaviours – bonding efforts as well as seeking extrinsic rewards and experiencing body worries. Fearful attachment predicted less sexual satisfaction, while preoccupied attachment unexpectedly predicted greater sexual satisfaction. These findings provide support for the associations between individual attachment styles and sexual behaviours and suggest the implications of sexual behaviours on intimate needs within relationships.

The relationship between siblings is unique in both its history and duration across the lifespan. Previous relationship researchers have examined siblings in childhood, but few have explored this distinctive relationship in adulthood. In this study, the adult sibling relationship was explored from an attachment perspective to determine the effect of an individual's attachment on conflict and collaboration with siblings. As expected, secure attachment predicted negative associations with conflict and positive associations with collaboration whereas insecure attachment (fearful, preoccupied, and dismissing) predicted opposite patterns. Results were compared to the abundance of literature on romantic relationships and findings from this study provided support for the theory that siblings function as attachment figures in adulthood.
