D.Litt. et Phil. / The aim of this study was to determine possible relationships between sense of coherence, temperament and decision-making and to explore the nature of these relationships. The study was based on the assumption that people attempt to make sense of complex environments and that differences in certain biological and psychological characteristics may lead to differences in the way that people make decisions in complex environments. Temperament was defined as a biological or physiological aspect that influences human behaviour. Sense of coherence was conceptualised as a psychological, global orientation that influences the way in which individuals understand their environments and can therefore give rise to individual differences in behaviour. Decision-making style was defined as a specific behavioural manifestation of the manner in which individuals make sense of complex environments and it was postulated that decision-making would probably be influenced by temperament and sense of coherence. In order to explore the current study’s research questions, a sample of 189 third year and Honours students in Psychology at a tertiary institution was used. The ages of the participants ranged from 19 tot 34 years and the average age was 22 years. More women (91.5%) participated in the study than men (8.5%). As a result of practicalities it was impossible to use a random sample. Three self-report measurements were used to respectively measure sense of coherence, temperament and decision-making style. These were the Orientation to Life Questionnaire, Pavlovian Temperament Survey and Melbourne Decision Making Questionnaire. The Pavlovian Temperament Survey measures three characteristics of the nervous system namely Strength of Excitation, Strength of Inhibition and Mobility of the Nervous Processes. An additional sub-scale was added to measure Balance of the Nervous Processes. The Orientation to Life Questionnaire measures Comprehensibility, Manageability, Meaningfulness as well as total Sense of Coherence. The Melbourne Decision Making Questionnaire measures four decision-making styles: one effective style, Vigilance and three ineffective styles, Procrastination, Hypervigilance and Buck Passing. The raw data that were collected from the completed questionnaires were subjected to several statistical analyses. The data were tested for normality of sub-scale distributions, which lead to logistical regression analyses being used to determine if temperament and sense of coherence can predict differences in decision-making style. Pearson product moment correlations as well as canonical correlations were also used. Multiple analyses of variance were used to determine whether biographical variables could account for any differences in sense of coherence, temperament and decision-making style. The results indicated that differences due to language, year of study or work status did not affect scores with regard to sense of coherence, temperament or decision-making style. The sample could therefore be regarded as quite homogeneous and the effect of confounding variables could be limited. However, generalisability of the results was also compromised. It was found that Strength of Excitation, Strength of Inhibition and Mobility of the Nervous Processes displayed relationships with Sense of coherence as well as the individual aspects of sense of coherence namely Comprehensibility, Manageability and Meaningfulness. This finding points to the possibility that physiological responses and psychological assessment of complex environments are related. Even though Balance of the Nervous Processes was not indicated as related to sense of coherence, it was found that this characteristic of the nervous system may possibly relate to decision-making. In line with these findings, the results indicated the possibility of relationships between a person’s psychological assessment of situations and behavioural outcomes as relationships were found between sense of coherence and decision-making style. It was indicated that certain temperament dimensions possibly displays an inverse relationship with decision-making styles, and especially the use of a hypervigilant decision-making style. However, the role of temperament in the use of a vigilant decision-making style is unclear. Lastly, the results indicated that the emotional assessment of stimuli as meaningful and challenging may possibly give rise to the use of a vigilant decision-making style. The assessment of situations as chaotic and unstructured could possibly relate more to the use of ineffective decision-making styles. An overall conclusion that can be made is that relationships between sense of coherence, temperament and decision-making style do indeed exist but that the nature of the relationships is quite complex. It seems as if different mechanisms are at play with regard to determining the use of effective and ineffective decision-making styles. These mechanisms could possibly lie in the emotional and cognitive assessments of situations. It seems as if a healthy emotional assessment of situations as challenging and meaningful precede the use of an effective, cognitively-based decision-making style. The cognitive assessment of situations as chaotic and unstructured could possibly lead to a more emotional decision-making response and decisions may be postponed, its responsibility may be shifted or it may be handled in a panicky manner. The results of this study should be interpreted with care since the sample was quite homogeneous and not particularly large. The exclusive use of the Melbourne Decision Making Questionnaire to measure decision-making is also problematic and the inclusion of an objective measurement of decision-making efficiency would have been preferable. It is also unclear whether reported decision-making style is equal to true decision-making style. Lastly, it was also decided to move away from Antonovsky’s (1987) recommendations that sense of coherence be treated as one global construct and the individual sub-scales were analysed separately. Future research can make use of similar variables and statistical techniques with bigger and more diverse samples to facilitate the development of an explanatory model for behaviour within complex environments. If the same variables are used, other measurements should be included to expand the conceptual framework. Future research could also test the current findings in practice for example in training or therapy.

Child temperament has been implicated as a possible mediator or moderator of the relation between parenting and child outcomes. However, previous studies have lead to ambiguous interpretation of the results due to methodological problems. Sanson et al., (2004) conducted a review of the relation between temperament and social development and outlined four methodological problems with previous research in the field of temperament, two of which were addressed in the current study. The present study examined the moderating role of the three broad child temperament factors on the relation between three forms of parenting practices, punitive discipline, deficient parenting, and poor parental monitoring and child aggressive behaviors. Using a multimethod and multisource design, parent report, child report, observational data, and behavioral tasks were used to create the construct when possible. The present study also controlled for other factors that have been linked to child aggressive behaviors, specifically, child age and gender, maternal personality, and economic disadvantage. Mother report and child report of the criterion were examined separately using hierarchical regression and full information maximum likelihood estimation in path analyses. Three hypotheses were tested: 1) high levels of child negative affectivity will moderate the relation between harsh/punitive discipline and the development of aggressive behavior problems, 2) a combination of inconsistent discipline and neglect, or deficient parenting, will predict aggressive behaviors in children with high levels of surgency, and 3) that poor parental monitoring will predict aggressive behaviors particularly for children low on effortful control. Results using child report of aggressive behaviors indicated that temperament did not moderate the relationship between parenting practices and aggressive; however, higher use of punitive discipline predicted higher levels of aggressive behaviors. The covariates age and maternal positive emotionality, predicted aggressive behaviors as well, with older children reporting higher rates of aggressive behaviors and higher levels of maternal positive emotionality predicting lower levels of aggressive behaviors in children. Using maternal report of aggressive behaviors, deficient parenting had a main effect on child aggressive behaviors, with higher use of deficient parenting predicted high aggressive behaviors. While temperament did not moderate the relation between parenting and aggressive behaviors using maternal report either, effortful control did have a main effect on aggressive behaviors. That is, higher levels of effortful control predicted lower levels of child aggressive behaviors. As for the parenting variables, only deficient parenting had a direct relation to aggressive behaviors. The covariate maternal negative emotionality also predicted higher levels of mother reported child aggressive behaviors. In summary, although unable to find a moderation effect for temperament, this study found support for harsh punitive discipline and deficient parenting as risk factors of aggressive behaviors in children and found support for effortful control and maternal positive emotionality as protective factors against aggressive behaviors. Results are interpreted in terms of treatment for child aggressive behaviors and the need to examine data from different sources in a non-aggregated manner.

This study examined the associations between behavioral inhibition in early childhood and patterns of social-emotional functioning in adolescence. As part of a larger longitudinal study on temperament and social development, adolescents who were recruited as infants completed two tasks to assess social-cognitive biases at follow-up: an information-processing task and an autobiographical memory task. The information-processing task assessed adolescents? interpretations of ambiguous situations. Next, adolescents completed an autobiographical memory task where they were exposed to both social and neutral-cued words, and recalled the first memory that came to mind. Memories were coded for specificity, affective tone, response latency, and emotional intensity. Afterwards, adolescents were also presented with a word recall task. In addition, shyness and socially anxious behaviors were observed as adolescents participated in a self-presentation speech task with an unfamiliar peer. Behavioral inhibition at age two was found to predict higher levels of observed anxious behaviors (self-presentation anxiety) during the peer interaction. This relation appears to be mediated by a pattern of blunted affect in response to socially-cued autobiographical memories. While the relation between temperament ratings of early behavioral inhibition and the blunted memory affect was content-specific to social-cued words, current self-presentation anxiety during the peer interaction was related to a more generalized bias that was not content-specific. In addition to the blunted memory affect, adolescent self-presentation anxiety was associated with less affective interpretations on the story task, poorer word recall, slowed response times, decreased emotional intensity.

Certain temperament traits that exist may be accurate predictors of the behaviour animals will exhibit towards stockpersons and their offspring after parturition. A total of 184 beef cattle in year 1 and 169 in year 2 (99 of these were also tested in year 1) were run through a chute complex and individually restrained before calving to see if their response predicted their behaviour after calving. Pre-calving measurements included exertion force applied against the headgate, a subjective temperament score, the response to a stockperson standing in front of the headgate and the exit speed from the chute. Within 2 d after calving, the cows response to her calf, stockpersons and a predator model were recorded during standardized testing. A blood sample from each calf was collected to measure total serum protein and the calfs adjusted 205 d weaning weight was recorded in year 1. A principal component analysis was used to reduce the number of variables. The components were then used to generate multiple regression trees. The results of this study indicated that many measures of maternal behaviour were not related to the temperament of the animal. The amount of time the cow spends greater than 3m from the calf when it is being handled was somewhat related to temperament; however, this variable may indicate fearfulness of people rather than maternal behaviour. It appears that a cows temperament is, in general, a poor predictor of maternal behaviour. A producer survey was also conducted on 168 cattle producers at 3 Saskatchewan cattle events. The cumulative number of cows owned by the respondents was 33,621, 5.7% of which were reported to be dangerous (cows the producer judged would hurt them after calving if given the chance). The majority of farms (76.2%) had at least one dangerous cow. Mis-mothering (i.e. the cow abandoned or did not care for her calf) had an incidence of 1.4% of cows, and occurred on 56.3% farms. Producers are more tolerant of aggressive cows and are less likely to cull them than cows which abandon or mis-mother their calves.

This study was conducted to determine if a relationship exists between temperament, stress response, and the shedding of Escerhichia coli O157:H7. Cattle (n = 150) were evaluated for disposition and stress response before shipping to the feeding operation, upon arrival at the feedlot, at approximately 70d on feed, and prior to transport to the harvesting facility. Chute and pen scores, as well as serum cortisol concentrations, were measured in order to assess individual temperament and stress response. A temperament index was created to classify cattle as Excitable, Intermediate, or Calm. The presence of E. coli O157:H7 was determined by rectal swabs on the live cattle and swabs of colons collected postmortem at the processing facility. As expected, variables for pre-shipment temperament index, exit velocity, pen score, arrival and midpoint exit velocity, and mid-point cortisol concentrations differed (P < 0.05) greatly between temperament groups. However, pre-shipment chute scores and cortisol concentration, as well as arrival and final cortisol concentrations differed (P < 0.05) only for Excitable cattle compared to both Calm and Intermediate groups. The percentage of cattle shedding the pathogen at arrival was approximately equal between temperament groups. When sampled before shipment to the processing facility, a higher proportion (P = 0.03) of cattle displaying Calm temperaments shed E. coli O157:H7 than the other groups. Results from postmortem colon samples exhibited a similar trend. When the results from all four sampling periods were pooled, the Calm cattle had a greater numerical percentage test positive for E. coli O157:H7. However, the pooled frequency distribution is largely dictated by the results of the final sampling time. Based on these results, it appears that Excitable cattle are not more likely to shed E. coli O157:H7. In fact, it seems that Calm cattle may be equally or more susceptible to shed at later points in the feeding period. However, it is important to note that a relatively small number of the samples tested positive for E. coli O157:H7, thus, potentially causing dramatic changes in the distributions.
