A rose in any other font would not smell as sweet: effects of perceptual fluency on categorization

Fluency--the ease with which people process information--is a central piece of information we take into account when we make judgments about the world. Prior research has shown that fluency affects judgments in a wide variety of domains, including frequency, familiarity, and confidence. In this paper, we present evidence that fluency also plays a role in categorization judgments. In Experiment 1, participants judged a variety of different exemplars to be worse category members if they were less fluent (because they were presented in a smaller typeface). In Experiment 2, we found that fluency also affected judgments of feature typicality. In Experiment 3, we demonstrated that the effects of fluency can be reversed when a salient attribution for reduced fluency is available (i.e., the stimuli are hard to read because they were printed by a printer with low toner). In Experiment 4 we replicated these effects using a within-subject design, which ruled out the possibility that the effects were a statistical artifact caused by aggregation of data. We propose a possible mechanism for these effects: if an exemplar and its category are closely related, activation of one will cause priming of the other, leading to increased fluency. Over time, feelings of fluency come to be used as a valid cue that can become confused with more traditional sources of information about category membership.     

Acquisition of dispositional attributions: effects of sample size and covariation

Two experiments examined whether dispositional attributions are sensitive to the sample size of the evidence indicating a given level of covariation between person and behavior. Participants were given high or low levels of covariation (i.e. consensus and distinctiveness), and the acquisition of dispositional attributions was monitored by requesting dispositional trait ratings at fixed intervals. The results showed that dispositional attributions were sensitive to sample size, and increased given more evidence on high person‐behavior covariation while they decreased given more evidence on low person‐behavior covariation. Additional analyses suggested that in making dispositional inferences (e.g. about the actor), there was a slight preference for agreement information (e.g. low distinctiveness) over difference information (e.g. low consensus). The effects of sample size are inconsistent with current statistical or probabilistic models of covariation, but are in line with connectionist networks using an error‐correcting learning algorithm.

Genetic and environmental determinants of temperament: a comparative study based on Polish and German samples

This study of 1555 adult mono‐ and dizygotic twins reared together estimates the heritability of temperament traits in a Polish and a German sample. We test whether the etiology of temperament traits differs between the two cultures and between different temperament traits. We assessed temperament traits with the Formal Characteristics of Behaviour–Temperament Inventory (FCB‐TI), the Pavlovian Temperament Survey (PTS), the Revised Dimensions of Temperament Survey (DOTS‐R), and the Emotionality–Activity–Sociability Temperament Survey (EAS‐TS). Taking error of measurement into account, genetic sources of variance explained about 50% of the variance of temperament traits. We found neither reliable cultural differences nor robust differences in the etiology of the traits. However, the four questionnaires differed systematically with respect to the proportion of genetic and environmental influences on their scales. Copyright © 2002 John Wiley & Sons, Ltd.     

Do difficulties with emotions inhibit help-seeking in adolescence? The role of age and emotional competence in predicting help-seeking intentions

We examined whether adolescents who are poor at identifying, describing, and managing their emotions (emotional competence) have lower intentions to seek help for their personal-emotional problems and suicidal ideation, as observed in adult studies. We also examined whether age moderated the relationship between competence and help-seeking. Two hundred and seventeen adolescents completed measures of emotional competence, help-seeking, hopelessness, and social support. Results indicated that adolescents who were low in emotional competence had the lowest intentions to seek help from informal sources (i.e., family and friends) and from some formal sources (e.g., mental health professionals), and the highest intentions to seek help from no-one. There was one important age-related qualification: difficulty in identifying and describing emotions was associated with higher help-seeking intentions amongst young adolescents but lower intentions among older adolescents. Social support, hopelessness, and sex could not entirely explain these relationships. Thus, even those who had high quality social support had less intention to use it if they were low in emotional competence.     

A longitudinal study of work-based, adult-youth mentoring

Using a longitudinal design, this study explored the relation of urban high school student attitudes toward school, work, and self-esteem beliefs to work-based mentoring, mentor satisfaction, and employment status. Participants included high school students taking part in a formal work-based mentoring program, students who established informal mentoring relationships at work, students who worked without a mentor, and students who were not employed during the academic year. While there were no significant group differences in the measures at the start of the year, results at the end of the year showed that students in the formal mentoring program believed more strongly that school was relevant to work than those who worked without a mentor. Students with mentors had higher levels of self-esteem than those who did not work. Students who were highly satisfied with their mentors had higher levels of self-esteem and believed more strongly that school was relevant to the workplace than students who did not work. The implications of these results are discussed and future research areas are identified.     

Emil Kraepelin's dream speech: A psychoanalytic interpretation

Freud's contemporary fellow psychiatrist Emil Kraepelin collected over the course of several decades some 700 specimens of speech in dreams, mostly his own, along with various concomitant data. These generally exhibit far more obvious primary-process influence than do the dream speech specimens found in Freud's corpus; but Kraepelin eschewed any depth-psychology interpretation. In this paper the authors first explore the respective orientations of Freud and Kraepelin to mind and brain, and normal and pathological phenomena, particularly as these relate to speech and dreaming. They then proceed, with the help of biographical sources, to analyze a selection of Kraepelin's deviant dream speech in the manner that was pioneered by Freud, most notably in his 'Autodidasker' dream. They find that Kraepelin's particular concern with the preservation of his rather uncommon family name-and with the preservation of his medical nomenclature, which lent prestige to that name-appears to provide a key link in a chain of associations for elucidating his dream speech specimens. They further suggest, more generally, that one's proper name, as a minimal characteristic of the ego during sleep, may prove to be a key in interpreting the dream speech of others as well.     

Replications and Limitations of a Two-Factor Model of Child Witness Credibility

Two experiments are reported that test the idea that jurors perceive child witnesses in terms of a 2-factor model of credibility with the factors defined as cognitive ability and honesty (Leippe & Romanczyk, 1987; Ross, Millers, & Moran, 1989). In the first experiment, 300 mock jurors watched a realistic videotaped recreation of a sexual abuse trial and rated the credibility of the child witness. Mock jurors perceived the child witness in terms of 2 factors: cognitive ability and honesty. Only honesty predicted verdict. These findings were replicated in Experiment 2 ( N = 300) when only the child's testimony was presented and the perceptions of the child witness were not contaminated by the testimony of the other witnesses in the trial.
