Who Delivers Justice? Source Perceptions of Procedural Fairness1

Tyler and Bies (1990) argue that how leaders enact and apply formal procedures can affect perceptions of procedural fairness as much as the formal procedures themselves. This study examined directly the extent to which workers see either formal policies and procedures or their supervisors as the source most responsible for the procedural fairness they receive in their performance evaluations. Group differences in these source perceptions between exempt and nonexempt workers were also explored. Results indicate that workers attribute the responsibility for procedural fairness jointly and independently to both their organization's formal policies and procedures and to their supervisors. Results at the group level of analysis indicate that nonexempt workers perceive formal policies and procedures to be more responsible for procedural fairness than do exempt workers. Implications of these findings are discussed.     

Mood-congruent and mood-incongruent learning

We report two experiments that investigate the effect of an induced mood on the incidental learning of emotionally toned words. Subjects were put in a happy or sad mood by means of a suggestion technique and rated the emotional valence of a list of words. Later on, they were asked to recall the words in a neutral mood. For words with a strong emotional valence, mood-congruent learning was observed: strongly unpleasant words were recalled better by sad subjects and strongly pleasant words were recalled better by happy subjects. The reverse was true for slightly toned words: here, mood-incongruent learning was observed. Both effects are predicted by a two component processing model that specifies the effect of the mood on the cognitive processes during learning. Further evidence for the model is given by rating times measured in Experiment 2.     

Asymmetric dependencies in perceiving identity and emotion: Experiments with morphed faces

We investigated whether an asymmetric relationship between the perception of identity and emo-tional expressions in faces (Schweinberger & Soukup, 1998) may be related to differences in the rela-tive processing speed of identity and expression information. Stimulus faces were morphed across identity within a given emotional expression, or were morphed across emotion within a given identity. In Experiment 1, consistent classifications of these images were demonstrated across a wide range of morphing, with only a relatively narrow category boundary. At the same time, classification reaction times (RTs) reflected the increased perceptual difficulty of the morphed images. In Experiment 2, we investigated the effects of variations in the irrelevant dimension on judgments of faces with respect to a relevant dimension, using a Garner-type speeded classification task. RTs for expression classifica-tions were strongly influenced by irrelevant identity information. In contrast, RTs for identity classifi-cations were unaffected by irrelevant expression information, and this held even for stimuli in which identity was more difficult and slower to discriminate than expression. This suggests that differences in processing speed cannot account for the asymmetric relationship between identity and emotion per-ception. Theoretical accounts proposing independence of identity and emotion perception are dis-cussed in the light of these findings.     

Predicting attendance at health screening: Organizational factors and patients' health beliefs

The present study firstly considers the effectiveness of two invite methods. Three hundred and twenty-five patients aged between 30 and 50 were invited to attend a general health check either by letter or opportunistically during a routine consultation After six months the two invite methods had similar attendance rates, although the opportunistic method produced fewer patients at screening and was biased in favour of females. The study also examined the health beliefs of attenders (n = 98) and non-attenders (n = 33) who had been sent questionnaires based on the health belief model prior to the commencement of the screening programme. Discriminant analysis revealed attenders to be more likely to report cutting back on everyday activities when ill and to believe in the seriousness of high blood pressure and weight problems. Non-attenders were found to be more worried about the screening appointment. These findings have important implications for those who plan screening services.     

Discriminant validity of the Multiple Affect Adjective Check List - revised

Four groups of patients (depressives, schizophrenics, substance dependents and abusers), a miscellaneous group of other patients, and a group of matched normals from a general population sample were compared on the scales of the Multiple Affect Adjective Check List - Revised (MAACL-R). All scales showed highly significant differentiation among the groups. An index consisting of Depression minus Positive Affect scales was particularly effective in discriminating between depressive and other groups. A discriminant function analysis showed that the depressive could be distinguished from other patient groups and normals with an accuracy of 72% correct. The normals could be distinguished from all of the patient groups with a 60% accuracy, and 87% if the substance abuser group is ignored. The discriminant validity among the nondepressive patient groups was not nearly as good.     

Raster versus calligraphic display devices for assessing visual performance: The influence of stimulus area and uncertainty

Sixty-hertz raster scan monitors provide relatively inexpensive solutions to problems associated with presenting complex visual stimuli. However, they restrict the user to displays in which stimulus characteristics cannot be changed more often than once every 16.67 msec. Calligraphic monitors allow very high frame rates, but not the generation of complex or chromatic images (unless very expensive monitors are purchased). A method is reported for increasing the frame rate of some raster monitors at the expense of the number of lines that are painted. Also, data relating to the influence of such a modification on visual performance is presented.     

Repetition learning in the immediate serial recall of visual and auditory materials

In 5 experiments, a Hebb repetition effect, that is, improved immediate serial recall of an (unannounced) repeating list, was demonstrated in the immediate serial recall of visual materials, even when use of phonological short-term memory was blocked by concurrent articulation. The learning of a repeatedly presented letter list in one modality (auditory or visual) did not transfer to give improved performance on the same list in the other modality. This result was not replicated for word lists, however, for which asymmetric transfer was observed. Inferences are made about the structure of short-term memory and about the nature of the Hebb repetition effect.     

Tau as a potential control variable for visually guided braking

D. N. Lee (1976) described a braking strategy based on optical expansion in which the driver brakes so that the target's time-to-contact declines around a constant slope in the range -0.5 < or = tau < 0. The present results from a series of braking simulations confirm and extend earlier reports (E. H. Yilmaz & W. H. Warren, 1995) that performance is broadly compatible with the tau hypothesis. However, performance was not enhanced in situations that favored the estimation of tau, and unlike in earlier reports, performance deteriorated in the absence of a ground plane that provided information about speed and target distance. This finding suggests that the tau hypothesis does not provide a complete account of braking control.     

Sequential modulations of interference evoked by processing task-irrelevant stimulus features

Compatibility level repetition benefits in interference paradigms have been taken to reflect enhanced processing selectivity in response to cognitive conflict elicited by a task-irrelevant stimulus feature. The authors demonstrate such sequential effects in the Simon task which (a) occur independent of previous behavioral conflict effects and (b) cannot be accounted for by selectivity enhancement. Furthermore, when presenting more than one type of irrelevant stimulus features, compatibility level repetition effects occurred in a type-specific manner. The results do not support the notion that cognitive conflict results in enhanced processing selectivity and favor a feature integration account.
