A cognitive process model is developed that predicts the 3 major symbolic comparison response time effects (distance, end, and semantic congruity) found in the results of the linear syllogistic reasoning task. The model assumes that people generate an ordering of a finite set of symbolic stimuli on the basis of information contained in the pairwise relations between adjacent stimulus items. The learning of this ordering is simulated within a simple connectionist framework. The decision-making component of the model utilizes 2 separate evidence accrual processes operating in parallel. One process accumulates information about the positional difference between the stimulus items being compared, and the other accumulates information about the endpoint status of each of those items. A response occurs whenever enough evidence favouring it has been accumulated within either of these processes. The model also assumes that the congruencies between the positions of the stimulus items within the ordering and the form of the comparative instruction can lead to either interfering or facilitating effects on the rate of evidence accumulation within each of these accrual processes. To test the model, data are obtained from the single-session performances of a group of 16 subjects and the multiple-session performances of an additional 2 subjects. The task is a variant of the one used by Trabasso, Riley, and Wilson (1975) and involves paired comparisons of ordered symbolic stimuli (three-letter names). Simulations of the model provide an excellent account of the group mean correct response times, as well as a very good account of the full set of data obtained from the 2 additional subjects (including percentage correct and response time distributional data).

Festinger (1954) postulated people desire social comparison to assess their abilities. Performance satisfaction was predicted to vary directly with the size of the comparison group since the accuracy of the appraisal would increase. Recently, Brickman and Bulman (1976) postulated that a drive exists for people to avoid social comparison. This is due to negative consequences arising from such encounters. To assess these two viewpoints 90 male and 90 female subjects were randomly assigned to either a positive skew, negative skew or equal score distribution based on false feedback from various perceptual-motor exercises. Each subject also was randomly assigned to an expected future comparison situation with a large group, a small group or the experimenter. Subjects desired social comparison to a greater extent in the small group situation than in the large group setting and least when meeting only with the experimenter. It appears that a curvilinear relationship exists between the desire for social comparison and the number of others being compared against. The desire for comparison reaches an apex in small group situations but decreases with larger numbers of others and in situations where there are no others for comparison.

Optimistiese self-evaluasies oor die vermoë om take uit te voer is belangrik vir sukses in verskeie aspekte van menswees. Wanneer mense sulke self-evaluasies doen en selfdoeltreffendheids-persepsies vorm maak hulle van inligting uit verskeie bronne gebruik. Volgens teorieë wat spesifiek verband hou met self-evaluasie is mense tydens die vorming van sulke persepsies omtrent die self veral afhanklik van inligting bekom deur sosiale vergelyking. Hierteenoor beklemtoon teorieë wat meer met selfdoeltreffendheid verband hou, die belangrikheid van self-verwysende inligting soos gevorm tydens prestasie-ervarings. Die doel met hierdie navorsing is om die ordening van die bronne van inligting, wat tydens die vorming van selfdoeltreffendheids-persepsies gebruik word, te ondersoek. Die resultate sal bydra om belangrike vrae te beantwoord oor die voorbereiding van mense vir die uitvoering van uitdagende take. In 'n eksperiment (N=1 723) wat op 'n Solomon-vier-groep-ontwerp geskoei is, is drie vorme van inligting wat persepsies kan beïnvloed aan drie eksperimentele groepe verskaf terwyl daar vyf kontrolegroepe was. Die effek van die ingrepe is met 'n vraelys gemeet. Die resultate toon dat selfdoeltreffendheidspersepsies meer deur selfverwysende inligting as deur sosiale vergelykings-inligting beïnvloed word. Dit is ook bevind dat die verskaffing van addisionele inligting nie 'n kumulatiewe effek tydens die vorming van selfdoeltreffendheidspersepsies het nie. Die implikasies van die resultate ten opsigte van die praktyk en teoretiese beskouinge is in die laaste instansie bespreek. / Optimistic self-evaluation regarding the ability to cany out tasks is important for success in various fields ofhuman endeavour. When people do such self-evaluations and fmm self-efficacy perceptions, they make use of information from various sources. According to theories related to self-evaluation, people engaged in forming such perceptions about themselves largely depend on information gained through social comparison. However, theories of self-efficacy emphasize the importance of self-referenced information, such as those formed through enactive attainments. The purpose of this research is to examine the collation of sources of information used in forming self-efficacy perceptions. The results will help to answer important questions about preparing people to perform challenging tasks. In an experiment (N=l 723) modelled on the Solomon Four Group Design, three types of information likely to influence perceptions were supplied to three experimental groups, while there were five control groups. The effects of the interventions were measured by means of a questionnaire. Results confirmed that perceptions of self-efficacy are more profoundly influenced by self-referenced information than by social comparisons. It was also found that additional information did not have a cumulative effect dming the forming of self -efficacy perceptions. The implications of the results with respect to practical and theoretical viewpoints are discussed in the final instance. / Psychology / D.Litt. et Phil. (Sielkunde)
