Temperament and character correlates of emotional processingRouse, Patrick Martin January 2013 (has links)
A hypothesised association between personality and emotional processing was
investigated within the framework of Cloninger’s psychobiological theory. According
to this model, personality development is based on the interaction between two
domains: temperament and character. A non-experimental, correlational design was
applied, using existing data from a sample of 630 South African first year psychology
students who completed the Temperament and Character Inventory (TCI) and the
University of Pennsylvania Computerised Neuropsychological Test Battery
(PennCNP). Canonical correlation analysis yielded significant associations between
character variables Self-Directedness, Cooperativeness, and Self-Transcendence as
measured and defined by the TCI and items from Penn Facial Memory Test (CPF)
and Penn Emotion Discrimination Task (ED40), respectively. In this exploratory
study participants lower in Self-Directedness and Cooperativeness were more
efficient in facial recognition compared to participants higher in these dimensions.
Conversely, individuals higher in Self-Directedness and Cooperativeness were more
accurate in the discrimination of happy and sad emotions, respectively. Participants
with higher Self-Transcendence performed better in facial recognition but were less
accurate in discriminating between happy and sad faces. These results affirm the
importance of further research into the association between temperament and
character and emotional processing. / Dissertation (MA)--University of Pretoria, 2013. / gm2013 / Psychology / unrestricted

An exploratory study of Novelty Seeking tendencies and students' performance on executive functioning tasksGous, Leah 04 July 2013 (has links)
In light of collated research linking temperament traits and executive performance, the aim of this study is to explore, in a large non-clinical sample, the differences in executive performance profiles among participants with different intensities of the trait Novelty Seeking (NS). A further aim is to establish which facets of NS contribute to these differences. The NS temperament dimension and its subscales were operationalised as scores on the Temperament and Character Inventory (TCI), which is based on the psychobiological theory of personality. The University of Pennsylvania Computerised Neuropsychological Test Battery (PennCNP) of executive functioning (EF) and abstract reasoning was used to measure participants’ neuropsychological EF. The total sample of participants (n= 461) was divided into high NS (n= 216) and low NS (n= 245) groups to investigate any significant differences between them. Further analysis was then conducted in order to analyse the relationship between the NS scale, the four subscales (Exploratory Excitability, Impulsiveness, Extravagance, and Disorderliness), and performance in executive tasks. The findings of this study indicated significant differences between groups with different intensities of NS, with the high NS group functioning notably better in performance and reaction time. Furthermore, this study showed that facets of NS, such as impulsiveness was a significant contributor to EF performance outcomes. / Dissertation (MA)--University of Pretoria, 2013. / Psychology / unrestricted

The influence of harm avoidance and novelty seeking temperament traits on emotional processingMuller, Jacomien 03 December 2012 (has links)
The purpose of this study is to explore the differences within specific temperament traits on emotional processing bias. Participants with extremes in temperament traits Harm Avoidance and Novelty Seeking were categorised and their performance on a computerised neuropsychological test battery was investigated. First year psychology students at a residential university in South Africa were invited to participate in the original study. Processing of the data yielded a realised sample of 431 participants who completed the Emotions battery, which comprised of four tasks. The results show that processing of affective valence varies according to individual differences within specific temperament traits. The findings suggest a negative emotion processing bias in the High HA group in comparison to the low HA group. Furthermore, the impulsive and extroverted High NS group show an increased ability to process emotional faces in comparison to the low NS group. The implications of these findings are discussed in the context of putative risk factors for psychopathological disorders. / Dissertation (MA)--University of Pretoria, 2013. / Psychology / unrestricted

The relationship between temperament, character and executive functioningDennison, Lisa Kim 23 August 2013 (has links)
Despite emergent attempts to connect temperament to a neurobiological etiology there has been little research that focuses on the relationship between temperament and character and neuropsychological test performance. Therefore, the aim of this study is to explore the relationship between temperament, character and performance on neuropsychological tests of executive functioning. Temperament and character dimensions were operationalized according to the Temperament and Character Inventory (TCI), a 240-item measure that is based on the psychobiological theory of personality. Neuropsychological performance was measured on the University of Pennsylvania Computerized Neuropsychological Test Battery (PennCNP), which is a test of executive functioning and abstract reasoning. The PennCNP comprised a test of Motor Praxis (MPRAXIS), the Penn Abstraction, Inhibition and Working Memory Task (AIM), the Letter-N-Back (LNB2), the Penn Conditional Exclusion Task (PCET), the Penn Short Logical Reasoning Task (SPVRT) and the Short Raven’s Progressive Matrices (SRAVEN). The sample comprised 422 first year psychology students at a residential university in South Africa. The results from this explorative study showed a moderate relationship between temperament, character and executive functioning. The temperament dimensions Novelty Seeking and Reward Dependence were positively related to AIM-NM, AIM and SPVRT, and inversely related to MPRAXIS. These results validate the importance of research that investigates the relationship between temperament and character dimensions and neuropsychological performance. / Dissertation (MA)--University of Pretoria, 2012. / Psychology / unrestricted

The relationship between temperament and serum serotonin concentration in migraine without auraHarvey, Jaqueline Ceridwyn 05 1900 (has links)
Cloninger’s Psychobiological Theory of Personality proposes four temperament dimensions, each underpinned by a different neurotransmitter system. The serotonergic system is purportedly linked to Harm Avoidance (HA). The aim of this study was to explore the relationship between HA and serotonin in migraine without aura (MO). A second aim was to explore the personality profile of MO patients. Sixty-six participants completed an online questionnaire and donated blood samples. Results indicated no significant association between HA and serotonin and a significant relationship between MO and HA. This study indicates that both Cloninger’s Psychobiological Theory of Personality and the Tridimensional Personality Questionnaire used for its assessment have value in South African personality research. In addition, the findings of the study reveal support for personality influences on the processes involved in migraine. This not only produces worthwhile avenues of research but also an alternative perspective for clinical practice. / Psychology / M.A. (Psychology (Research Consultation))
