Applied research on judgment formation, e.g. in education, is interested in identifying the underlying judgment rules from empirical judgment data. Psychological theories and empirical results on human judgment formation support the assumption of compensatory strategies, e.g. (weighted) linear models, as well as non compensatory (heuristic) strategies as underlying judgment rules. Previous research repeatedly demonstrated that linear regression models well fitted empirical judgment data, leading to the conclusion that the underlying cognitive judgment rules were also linear and compensatory. This simulation study investigated whether a good fit of a linear regression model is a valid indicator of a compensatory cognitive judgment formation process. Simulated judgment data sets with underlying compensatory and noncompensatory judgment rules were generated to reflect typical judgment data from applied educational research. Results indicated that linear regression models well fitted even judgment data with underlying non compensatory judgment rules, thus impairing the validity of the fit of the linear model as an indicator of compensatory cognitive judgment processes.

This paper focuses on intervention modules to improve teachers’ diagnostic competence, especially in regards to decisions on students’ transition from primary to secondary education. Although these transition decisions should be based on academic achievement, research has shown non-academic variables to influence decisions, leading to disadvantages for specific groups of students. Using an experimental pre-post design, we investigated the short and long term effects of accountability, theoretical knowledge and the application of prediction rules on teachers’ judgment accuracy, respectively. Pre-intervention data showed that although teachers’ decision accuracy was of high standard, decision accuracy for ethnic majority students was significantly higher than for ethnic minority students. Increased accountability resulted in increased decision accuracy, especially in regards to decisions for ethnic minority students. Similarly, the introduction of theoretical models of decision making and judgment formation and the application of prediction rules also resulted in an improvement of transition decisions but only for ethnic minority students. Unfortunately, the differential intervention effects of the intervention modules could not be maintained over time, that is, at follow up, the ethnicity bias reappeared. From these studies we can conclude that all three intervention modules can improve the accuracy of teachers’ transition decisions. In line with the intention of the interventions, the disproportionally high rate of decision errors for ethnic minority students observed pre-intervention was eliminated post-intervention and in line with error rates for ethnic majority students. However, training or instruction should be repeated briefly before making such judgments as their influence was not maintained over time. [less ▲]

In social encounters, language is one of the most salient cues eliciting evaluative responses. According to models on language attitudes (e.g., Cargile, Giles, Ryan & Bradac, 1994), listeners` attitudes towards the speaker`s language influence the evaluation of this speaking person. However, linguistic stimuli might evoke additional inferences, e.g. on speaker`s nationality. We are therefore experimentally testing whether attitudes towards languages and attitudes towards speaker`s nationality are two distinguishable constructs which has not been addressed in previous research. Furthermore, the distinction between implicit and explicit attitudes is examined, resulting in a theoretical framework of four distinct types of attitudes influencing speaker evaluations. Luxembourg`s linguistic context is determined by the existence of various languages spoken by different inhabitants. In the present study, the model is tested with Luxembourgish and French. Using a combination of explicit measures and an adapted audio Implicit Association Test (IAT; Greenwald et al., 2002), language and national attitudes of Luxembourgish university students are assessed. According our hypotheses, it is expected that language attitudes correlate moderately with national attitudes, providing evidence for the factorial separability. Results of regression analyses are discussed to give insight into the predictive impact of the four attitude types on speaker evaluations. A comparison between implicit and explicit attitudes is put into focus to demonstrate the model’s relevance. Overall, this study contributes to ascertaining the complexity of influencing factors on person perception based on linguistic cues by treating language and national attitudes as distinguishable constructs.

Social cognition research has demonstrated that processes of memory and judgment formation are not only affected by information type but also by the sequence in which this information is received. These sequence (i.e. primacy and recency) effects are of special interest if the first or last information activates a social category, as this may increase the risk of stereotypical biases in decision making. This may be especially pertinent to the educational domain as studies have shown teachers´ judgments are influenced not only by students´ academic achievement but also their social background. Therefore, this study investigated primacy effects in the assessment of student performance. This study not only assessed the impact of sequence on memory and judgment, but also measured attention via eye-tracking techniques, hence offering a more detailed test of the assumption of the primacy effect (i.e. increased attention to the first piece of information). Forty participants were presented four student descriptions, containing information on the student’s grades, standardized test results, working behavior and social background. For half of the participants, social background information was presented in the top left position on the screen and grade information in the top right position. For the other half these positions were switched. The sequence of information was therefore not predefined by the experimenter, but left to the participant, however, given the left-to-right and top-to-bottom orientation common in Western European languages, the information in the top-left position was expected to draw initial attention of participants. After reading each student description, participants recommended a fitting secondary school track and later recalled student information. The design of the study is a 2×2 factorial design, with the position order (social background vs. grades in top-left position) as a between-subject factor and type of information (social background vs. grades) as a within-subject factor. According our expectations, eye-movements (i.e. fixations during the first second of presentation), showed a significant effect of the position order. Information in the top-left position received not only more initial attention, but also more attention throughout, than the same information positioned in the top-right position, thus indicating a primacy effect in attention. This result was only partially reflected in the recall data, and no differences resulted in the accuracy of judgments. The results confirmed that the positioning of simultaneously presented information leads to a primacy effect in attention, but does not produce primacy effects in subsequent memory and judgments. In regard to the common structure of various dossiers and records, which first list a student’s name and personal information, these findings imply that such structure may maximize teachers’ attention to social background information, stating a potential source of social disparities in educational systems.
