Illness representations: a prototype approach

Two experiments tested the hypothesis that laypeople cognitively organize and recall information about physical symptoms according to prototyped conceptions they have of physical diseases. Based on pilot studies that identified the extent to which subjects associated specified symptoms with specific diseases, symptom sets were assembled to vary in the extent to which the symptoms were perceived to be associated with (to be prototypical of) a given disease. Experiment 1 asked subjects to indicate whether a given set of symptoms indicated a disease and, if so, which one. Experiment 2 tested subjects' recall for symptom sets varying in prototypicality for given diseases and also tested the effects on recall of giving subjects a diagnosis. Results of both experiments support the prototype hypothesis that information about physical symptoms is organized and processed according to people's preexisting beliefs about the association between particular symptoms and diseases. Implications for illness behavior and help seeking are discussed.     

Uncertainty reduction, self-enhancement, and ingroup identification

Two experiments tested the prediction that uncertainty reduction and self-enhancement motivations have an interactive effect on ingroup identification. In Experiment 1 (N = 64), uncertainty and group status were manipulated, and the effect on ingroup identification was measured. As predicted, low-uncertainty participants identified more strongly with a high- than low-status group, whereas high-uncertainty participants showed no preference; and low-status group members identified more strongly under high than low uncertainty, whereas high-status group members showed no preference. Experiment 2 (N = 210) replicated Experiment 1, but with a third independent variable that manipulated how prototypical participants were of their group. As predicted, the effects obtained in Experiment 1 only emerged where participants were highly prototypical. Low prototypicality depressed identification with a low-status group under high uncertainty. The implications of these results for intergroup relations and the role of prototypicality in social identity processes are discussed.     

Prototypes are attractive because they are easy on the mind

People tend to prefer highly prototypical stimuli--a phenomenon referred to as the beauty-in-averageness effect. A common explanation of this effect proposes that prototypicality signals mate value. Here we present three experiments testing whether prototypicality preference results from more general mechanisms-fluent processing of prototypes and preference for fluently processed stimuli. In two experiments, participants categorized and rated the attractiveness of random-dot patterns (Experiment 1) or common geometric patterns (Experiment 2) that varied in levels of prototypicality. In both experiments, prototypicality was a predictor of both fluency (categorization speed) and attractiveness. Critically, fluency mediated the effect of prototypicality on attractiveness, although some effect of prototypicality remained when fluency was controlled. The findings were the same whether or not participants explicitly considered the pattern's categorical membership, and whether or not categorization fluency was salient when they rated attractiveness. Experiment 3, using the psychophysiological technique of facial electromyography, confirmed that viewing abstract prototypes elicits quick positive affective reactions.     

Acts and dispositions: A reconsideration of the Act Frequency Approach

The Act Frequency Approach (AFA) proposed by Buss and Craik was summarized and critically reviewed on the basis of a German replication study using six interpersonal traits each with 100 translated acts. The six traits studied were dominant, gregarious, agreeable, submissive, aloof, and quarrelsome. The internal structure of these categories was examined via multiple prototypicality ratings. It was demonstrated that many acts are highly prototypical for more than one category. The manifested categorical structure was tested by gathering retrospective act reports about performance and frequency of exhibiting each of these 600 acts using a sample of 213 adults. Aggregation of the acts according to their prototypicality key yielded reliable subscales. The validities obtained on the basis of the 25 highly prototypical acts were slightly higher compared with those of the 100 act set, as well as the sets with lower prototypicality. The validity gradient proposed by Buss and Craik was found using selected personality scales as well as global self-ratings and peer-ratings on some of the respective trait terms. In general, the results of the German study replicated the findings of Buss and Craik.     

At the core of cyberaggression: A group-based explanation

In this study, prototypicality of the aggressor was tested as a group-level factor predicting social media users’ active participation in cyberaggression. Participants were exposed to a fictitious conversation, in which either a prototypical versus non-prototypical user posted an aggressive comment as a reply to a provocative comment. In line with self-categorization theory, we hypothesized that bystander participants would post an aggressive comment and rate the aggression as acceptable to a greater extent in the prototypical than in the non-prototypical condition. Furthermore, we predicted that perceived normativity of aggression would mediate the effect of prototypicality. Results supported these predictions and showed that prototypical members affect the extent to which collective aggressive behaviors in online interactions are approved and enacted. These findings highlight the importance of group-level factors in the study of cyberaggression and provide important information for understanding the psychological underpinnings of collective forms of online aggression.     

The instrumental use of group prototypicality judgments

Recently, Waldzus et al. [Waldzus, S., Mummendey, A., Wenzel, M., & Boettcher, F. (2004). Of bikers, teachers and Germans: Groups’ diverging views about their prototypicality. British Journal of Social Psychology, 43, 385-400] have shown that ingroup members often tend to judge the ingroup as more prototypical of the superordinate group than other subgroups. In this paper, we argue that, in addition to the motivational processes that have been posited to explain this phenomenon, prototypicality judgments may vary according to instrumental considerations. In particular, those who believe their ingroup interest to be undermined by remaining part of the common group will downplay ingroup’s prototypicality as a way to sustain their separatist position. In a first study (N = 63), we found that Scottish respondents who support Scottish independence judged the Scots to be less prototypical of Britain than the English, as compared with Scots who do not support independence. In a second study (N = 191), we manipulated the rhetorical context within which prototypicality judgments were made. Results showed that the pattern found in study 1 only applied when the issue of independence was made salient. When the issue of the importance of Scottish history in Britain was made salient, the opposite pattern appeared, i.e. supporters of independence judged the Scots more prototypical than the English compared to non-supporters. These results were also interpreted in instrumental terms.     

Leadership and Perceiver Cognition: Examining the Role of Self-Identity in Implicit Leadership Theories

We investigated whether priming individuals' self-identities to be interdependent or independent influences their ratings of leadership prototypicality. Specifically, we predicted that participants receiving an interdependent prime would rate items associated with transformational leadership as being more prototypical of effective leadership than would participants receiving no prime. We also predicted that participants receiving an independent prime would rate transactional leadership items as being more prototypical of effective leadership. Undergraduate psychology students were randomly assigned to one of three conditions (interdependent prime, independent prime, and control). Results support the idea that self-identity can be primed to influence ratings of leadership prototypicality. We discuss implications and suggest directions for future research.     

Children's identification of actors and patients in prototypical and nonprototypical sentence types

This research examined if children organize language categories around a prototype. Based on previous research with adults, the hypothesis held that the prototypical transitive sentence contains an animate actor and patient and a highly prototypical verb. The question of interest was if factors that contribute to adult judgments of sentence prototypicality (such as actor-patient animacy and verb prototypicality) affect young childrens' accuracy in correctly identifying sentence actors and patients. That is, are children more likely to make correct identifications in prototypical sentences? Sixty-four 2- and 4-year-old children were trained to to ntify sentence actors and patients in prototypical or nonprototypical sentences and then tested for generalization to sentences of other types. Two factors, verb prototypicality and animacy of sentence participants, combined to influence children's accuracy in actor/patient identification. Regardless of training condition, children produced more correct responses to sentences with animate actors than to sentences with inanimate actors. There was an interaction with verb prototypicality such that it was more typical for inanimate actors to act upon animate patients with what are otherwise low prototype verbs (e.g., low in action, low in intentionality). The results of the study are consistent with the view that similar cognitive mechanisms operate in language and in other nonlinguistic cognitive domains.     

Testing the speech unit hypothesis with the primed matching task: Phoneme categories are perceptually basic

The basic speech unit (phoneme or syllable) problem was investigatedwith the primed matching task. In primed matching, subjects have to decide whether the elements of stimulus pairs are the same or different. The prime should facilitate matching in as far as its representation is similar to the stimuli to be matched. If stimulus representations generate graded structure, with stimulus instances being more or less prototypical for the category, priming should interact with prototypicality because prototypical instances are more similar to the activated category than are low-prototypical instances. Rosch (1975a, 1975b) showed that, by varying the matching criterion (matching for physical identity or for belonging to the same category), the specific patterns of the priming × prototypicality interaction could differentiate perceptually based from abstract categories. Bytesting this pattern forphoneme and syllable categories, the abstraction level of these categories canbe studied. After finding reliable prototypicality effects for both phoneme and syllable categories (Experiments 1 and 2), primed phoneme matching (Experiments 3 and 4) and primed syllable matching (Experiments 5 and 6) were used under both physical identity instructions and same-category instructions. The results make clear that phoneme categories are represented on the basis of perceptual information, whereas syllable representations are more abstract. The phoneme category can thus be identified as the basic speech unit. Implications for phoneme and syllable representation are discussed.     

Towards tolerance: Representations of superordinate categories and perceived ingroup prototypicality

According to Mummendey and Wenzel (1999), group members tend to perceive their ingroup, relative to an outgroup, as more prototypical of the superordinate category encompassing both groups. Hence, they tend to regard the outgroup as deviating from the norms of the superordinate category. Factors that inhibit perception of relative ingroup prototypicality should thus promote intergroup tolerance. In two experiments, the representation of the superordinate category was manipulated. Both an undefinable prototype (Experiment 1; N=63) and a complex representation (Experiment 2; N=88) led to a decrease in relative ingroup prototypicality. Dual identification with the ingroup and the superordinate category increased relative ingroup prototypicality, which was negatively correlated with positive attitudes towards the outgroup. The findings supported Mummendey and Wenzel’s assumptions about the conditions that lead to intergroup tolerance.     

Effort in the face of difference: Feeling like a non‐prototypical group member motivates effort

Three studies examined the relationship between individuals' perceived “prototypicality” in a group, their subsequent self‐presentation goals, and individual effort in that group. Consistent with the finding that feelings of marginal ingroup membership status elicit a desire to seek stronger social connections within ingroups, we predicted that non‐prototypical group members will have more salient self‐presentation goals than prototypical members, and as such will exert more individual effort to exhibit the value of their membership to the group. Correlational Study 1 confirmed that non‐prototypical group members may be more likely than prototypical members to volunteer for activities that would benefit their group. Two experimental studies were then conducted to test the causal influence of feelings of prototypicality while also identifying theoretically relevant moderating conditions of perceived task efficacy (Study 2) and public versus private task performance (Study 3). These findings suggest that effortful performance in groups is partly motivated by the desire to foster social ties. Copyright © 2012 John Wiley & Sons, Ltd.     

On being peripheral: effects of identity insecurity on personal and collective self‐esteem

We examined collective self‐esteem and personal self‐esteem as a function of anticipated changes in one's prototypicality within a valued ingroup. In Study 1 (N = 80), all participants received information that they were currently peripheral group members. Expectations for the future were then manipulated, with some expecting to become more prototypical and others expecting they would be even more peripheral in the future. In addition, the source of future movement (either the group or the self) was varied. It was found that when the group was the source of movement, those who expected to shift to a more prototypical position in the future had higher collective self‐esteem than those who expected to change to an even more peripheral position. In contrast, those who anticipated an even more peripheral position had higher personal self‐esteem than those who expected to become more prototypical in the future. In Study 2 (N = 100), intragroup position at present (peripheral versus prototypical) and future intragroup position (peripheral versus prototypical) were manipulated orthogonally. It was found that future expectations only affected self‐esteem among those with an insecure current identity, but not among those who were currently prototypical of the ingroup. In addition, ingroup favoritism was mediated by self‐esteem changes among those whose identity was insecure. The importance of a dynamic framework for investigating group processes is stressed.

Conversation as a resource for influence: evidence for prototypical arguments and social identification processes

Members of eight single‐sex groups each consisting of three pro‐ and three anti‐capital punishment adherents discussed their views for 30 minutes, and afterwards individually rated ingroup and outgroup members on social influence ranking, prototypicality, and social attractiveness. From the intragroup hypothesis that speaking turns are a resource for influence (Ng & Bradac, 1993), we predicted and found that turns were correlated strongly with influence in the intergroup context. Further, using self‐categorization theory (SCT; Turner, 1985), we hypothesized that social identity processes would interact with turns, especially with turns obtained through interruptions. Interruptions encoded in prototypical utterances were more strongly correlated with social influence and prototypicality, but not social attraction, than interruptions encoded in non‐prototypical utterances. Further, interruption attempts enacted in prototypical utterances were found to be more likely to be successful than unsuccessful in obtaining turns, while those enacted in non‐prototypical utterances were more likely to be unsuccessful than successful. Additionally, interruption turns were longer when enacted in prototypical over non‐prototypical utterances. Overall, the findings suggest that the power/influence of language is interactively organized and constructed around salient self‐categorizations. Copyright © 2000 John Wiley & Sons, Ltd.     

We Are the World—and They Are Not: Prototypicality for the World Community,Legitimacy, and Responses to Global Inequality

The relation between developed and developing countries is characterized by inequalities that sometimes hinder actions against worldwide problems. The current research presents an intergroup approach, based on the ingroup projection model, towards an analysis of psychological processes that perpetuate global inequality on a social group level. Precisely, we argue that people from developed countries perceive their group as more prototypical for the world population than they perceive people from developing countries. These perceptions of ingroup prototypicality should in turn relate to legitimacy beliefs and predict unfavorable behavioral intentions towards developing countries. We present two studies that corroborate our hypotheses: In Study 1, participants from a developed country perceived their ingroup as more prototypical for the superordinate group (i.e., world population) than the outgroup (i.e., developing countries), which in turn was related to beliefs that global inequality is legitimate. This finding was replicated in Study 2, and the predicted effect of ingroup prototypicality on behavioral intentions was mediated by legitimacy beliefs. These findings demonstrate that intergroup processes can contribute to perpetuating global inequality.     

Typhoid Pollyanna: The effect of category valence on retrieval order of positive and negative category members

Previous research suggests that people process pleasant information more efficiently than unpleasant information. This phenomenon has been illustrated in a variety of contexts and paradigms, and is frequently referred to as the Pollyanna principle. One important aspect of the Pollyanna principle is that people tend to retrieve pleasant members of a category from semantic memory prior to unpleasant members of the same category. However, we propose that the retrieval advantage of favourably viewed category members holds only for positive categories and that prototypicality of category members might be a better predictor of ease of retrieval than favourability. These possibilities were tested in two studies. In Study 1, favourability effects on retrieval order were observed for positive categories but not for neutral or negative categories. In Study 2, prototypical category members were retrieved before less prototypical category members for both positive and negative categories. These results suggest that the Pollyanna principle might be the result of a confound between favourability and prototypicality for members of favourable categories.     

‘Of the group’ and ‘for the group’: How followership is shaped by leaders' prototypicality and group identification

Previous research has focused on the importance of leaders being seen to be of the group (i.e. to be prototypical of a group) but less on the impact of leaders' own degree of identification with the group. Also, little is known about the combined impact of leader prototypicality and leader identification on followers' responses. This paper reports two studies that address these lacunae. Study 1 shows experimentally that perceived leader identification and prototypicality interact to determine followers' personal identification with leaders and their perceptions of leader charisma. Findings indicate that high identification can compensate for low prototypicality such that high‐identified leaders are able to inspire followership when leaders are low prototypical. Study 2 replicates these findings in the field by examining followers' responses to workgroup leaders. In addition, results demonstrate that the aforementioned responses are more pronounced for highly identified followers. The present research extends social identity theorizing by demonstrating that leaders' inability to inspire followership derives as much from their failure to project a sense of ‘we’ and ‘us’ as part of their self‐concept as from a failure to exemplify group‐typical attributes.

Predicting cognitive development and early symptoms of autism spectrum disorder in preterm children: The value of temperament and sensory processing

This study was the first to longitudinally explore the extent to which early temperament and sensory processing were of predictive value for cognitive development and Autism Spectrum Disorder (ASD) symptomatology in a sample of preterm children (N = 50, 22 girls, mean gestational age 27 weeks). At the corrected ages of 10, 18, and 24 months, sensory processing and temperament were assessed, as were cognitive development and ASD symptoms at 36 months. Better cognitive development was predicted by fewer hospitalisation days at birth and by lower Activity Level at 18 months. Temperamental subscales of Negative Affect showed associations with both parent-reported and observational measures of ASD symptomatology, whereas sensory processing only had predictive value for parent-reported symptoms of ASD. The usefulness of temperament and sensory processing for prediction of ASD symptom severity and cognitive outcomes became clear in the second year of life. The results indicate that this area of research is worth additional investigation in the extreme and very preterm population, to explore in further detail whether these two concepts might be able to provide information about which preterms are more likely to develop ASD or cognitive impairments.     

When different means bad or merely worse. How minimal and maximal goals affect ingroup projection and outgroup attitudes

Group members tend to perceive their ingroup relative to an outgroup as more prototypical for a common superordinate group because they project features of their ingroup onto the superordinate group. As a consequence, the ingroup is perceived as more positive than the outgroup (Mummendey & Wenzel, 1999). We extend the ingroup projection model by examining different types of ingroup goals: minimal and maximal goals as well as actual and ideal goals. Minimal goals should engender either‐or thinking and lead to more ingroup projection compared with maximal goals that should involve more nuanced thinking. Ingroup prototypicality in terms of ideal goals (e.g., what we ideally should strive for) was expected to show a stronger relation to outgroup attitudes than ingroup prototypicality in terms of actual goals (e.g., what we are actually striving for). We manipulated minimal and maximal goal orientation and assessed actual and ideal goals. Across two studies, relative ingroup prototypicality was higher in the minimal compared with the maximal goal condition. Moreover, ingroup prototypicality referring to ideal goals showed a stronger relation to outgroup evaluation than ingroup prototypicality referring to actual goals.
