Evaluating the predictive validity of personality trait judgments using a naturalistic behavioral criterion: A preliminary test of the self-other knowledge asymmetry model

We tracked 87 participants over two days using the Electronically Activated Recorder (EAR). Coded variables included expressions of mood, amount of talking in various situations (e.g., with one other person, with a friend, etc.), locations, and behavioral markers of the Big Five. Collection of self-, informant-, and stranger-ratings on markers of the Big Five allowed for a unique test of the Self-Other Knowledge Asymmetry (SOKA) model. Although effect sizes were modest, there was evidence for the validity of both self- and informant-ratings across most trait dimensions. Stranger-ratings showed evidence of validity in the domain of Extraversion. Predictions derived from the SOKA model were partially supported, though more research with larger samples is needed to provide stronger tests of SOKA.     

The Role of Lexical Frequency in the Acceptability of Syntactic Variants: Evidence From that‐Clauses in Polish

A number of studies report that frequency is a poor predictor of acceptability, in particular at the lower end of the frequency spectrum. Because acceptability judgments provide a substantial part of the empirical foundation of dominant linguistic traditions, understanding how acceptability relates to frequency, one of the most robust predictors of human performance, is crucial. The relation between low frequency and acceptability is investigated using corpus‐ and behavioral data on the distribution of infinitival and finite that‐complements in Polish. Polish verbs exhibit substantial subordination variation and for the majority of verbs taking an infinitival complement, the that‐complement occurs with low frequency (<0.66 ipm). These low‐frequency that‐clauses, in turn, exhibit large differences in how acceptable they are to native speakers. It is argued that acceptability judgments are based on configurations of internally structured exemplars, the acceptability of which cannot reliably be assessed until sufficient evidence about the core component has accumulated.     

Are you sure about that? Eliciting confidence ratings may influence performance on Raven's progressive matrices

Confidence ratings (CR) have often been integrated into reasoning and intelligence tasks as a means for assessing meta-reasoning processes. Although it is often assumed that eliciting these judgements throughout reasoning tasks has no effect on the underlying performance outcomes, this is yet to be established empirically. The current study examines whether eliciting CR from participants during a fluid-reasoning task influences their performance and how this effect is moderated by their initial self-confidence in their own reasoning abilities. In a first experiment, we found that participants performing CR during Raven's Progressive Matrices significantly outperformed a control group who did not provide ratings. Additionally, a second experiment demonstrated that CR only facilitated performance in participants who have a high level of initial self-confidence in their reasoning ability, whereas they were detrimental to participants low in self-confidence.     

Less is more: Online consumer ratings' format affects purchase intentions and processing

Online customer ratings of products and services are commonplace in e‐commerce; however, the format in which these ratings are presented to consumers can vary. Although not anticipated by classical models of decision making, latter models such as prospect theory and feelings‐as‐information theory suggest that the presentation format of online customer ratings could affect subsequent consumer decision making. In the present research, 3 empirical studies test whether online customer ratings' formats differentially affect consumer purchase intentions. The results offer support for feeling‐as‐information theory and suggest that online ratings presented in a mean (vs. distribution) format result in higher purchase intentions as a result of increased processing fluency. Implications for the presentation of online consumer ratings in e‐commerce, based on these findings, are addressed.     

When two paradigms meet: Does evaluative learning extinguish in differential fear conditioning?

Contemporary theories of Pavlovian conditioning propose a distinction between signal learning (SL), in which a conditioned stimulus (CS) becomes a predictor for a biologically significant unconditioned stimulus (US), and evaluative learning (EL), in which the valence of the US is transferred to the CS. This distinction is based largely on the different susceptibilities of EL and SL to extinction. This study compared the extinction of indices of EL (online valence ratings) and SL (US-expectancy ratings and skin conductance responses, SCRs) in a differential fear conditioning design using complex CSs. Only half of the participants gave online valence ratings, allowing us to confirm that online valence measurement did not influence SCRs. In line with the distinction between EL and SL, SCRs extinguished rapidly while valence ratings showed resistance to extinction. US-expectancy ratings, however, were not distinguishable from valence ratings indicating that verbal indicators of EL and SL share a similar time course.     

Item Response Theory Analyses of the Parent and Teacher Ratings of the DSM-IV ADHD Rating Scale

The graded response model (GRM), which is based on item response theory (IRT), was used to evaluate the psychometric properties of the inattention and hyperactivity/impulsivity symptoms in an ADHD rating scale. To accomplish this, parents and teachers completed the DSM-IV ADHD Rating Scale (DARS; Gomez et al., Journal of Child Psychology and Psychiatry, 40, 265–274, 1999) for a group of 1,475 primary school-aged children. The results for the discrimination parameters showed that all symptoms for both groups of respondents were generally good for discriminating their respective latent traits. For virtually all symptoms, their threshold values showed moderate to large increases in the level of the latent trait at each subsequent response dichotomy, with the symptoms being especially good at representing the appropriate traits from mean to moderately high trait levels. The item information function values for most symptoms indicated reasonable reliability from, approximately, the mean trait levels to moderately high trait levels. These findings indicate good psychometric properties for the parent and teacher ratings of the DARS. The implications of the findings for the use of the DARS and other similar scales are discussed.     

The measurement of body-image dissatisfaction–satisfaction: Is rating importance important?

Some researchers have argued that evaluative body image may be better assessed by measures that weight dissatisfaction–satisfaction ratings by their subjective importance to individuals. The Body Areas Satisfaction Scale (BASS) is a frequently used, standardized assessment of evaluative body image, albeit one that does not use differential item weights. This investigation, with 410 female and male college students, examined whether an importance-weighted revision of the BASS would have incremental validity relative to the original version in the prediction of multiple criterion variables. Results confirmed the reliability and validity of unweighted and weighted versions. However, the validity of weighted versions did not surpass that of the original BASS. The extremity of individuals’ satisfaction and dissatisfaction ratings appears inherently to reflect the importance placed on physical attributes for self-evaluation. Moderated regression analyses offered only weak support for the interaction of average satisfaction and average importance ratings beyond their main effects. The simpler, unweighted BASS is an acceptable assessment of evaluative body image.     

Genetic and environmental influences on aggression in 4- to 7-year-old twins

Aggressive behaviors of 38 twin pairs (21 monozygotic [MZ], 17 dizygotic [DZ]) between the ages of 4 and 7 years were assessed through mothers' ratings and observations in their homes. An observation checklist was developed in which mothers were asked to observe and report each child's specific aggressive behaviors for a total of 6 hours spread over 3 days. In particular the observations focused on the following behaviors: rejection, destructiveness, negativism, noncompliance, teasing, physical negative, insult, verbal threat, and yelling. Biometrical genetic analysis evidenced significant heritable influences on composite aggression scores in both the observation checklist and the mothers' ratings; heritability estimates varied from.24 to.94 depending on the aggression nieasnre used, with scores from the mothers' observations demonstrating smaller genetic effect than those of the parental ratings of the environmental sources of variance, within-family factors were far more important than the between-family ones. The results also yielded significant sex and zygosity differences for means of some of the specific aggressive behaviors, where males and DZ twins scored higher than females and MZ twins. It was suggested that future studies should include more detailed investigations of the context in which specific aggressive behaviors occur and the sources toward which they are directed in order to determine the extent to which different types of aggression may have different etiologies.     

Prospective prediction of academic performance in college using self- and informant-rated personality traits

Five-factor personality ratings were provided by undergraduate freshmen, their parents, and their college peers as predictors of cumulative GPA upon graduation. Conscientiousness ratings were significant predictors of GPA by all three raters; peer ratings of Conscientiousness were the only significant predictor of GPA when self-, parent-, and peer-ratings of Conscientiousness were examined simultaneously. College major was a moderator of this relationship, with self- and parent-ratings of Conscientiousness correlating more strongly with GPA among Social Science majors and parent-ratings of Conscientiousness correlating less strongly with GPA among Science majors. These findings replicate existing research regarding the validity of informant ratings as predictors of behavioral outcomes such as academic performance, while emphasizing the importance of including multiple informants from various life contexts.     

Social desirability in personality inventories: Symptoms,diagnosis and prescribed cure

An analysis of social desirability in personality assessment is presented. Starting with the symptoms, Study 1 showed that mean ratings of graded personality items are moderately to strongly linearly related to social desirability (Self Deception, Impression formation, and the first Principal Component), suggesting that item popularity may be a useful heuristic tool for identifying items which elicit socially desirable responding. We diagnose the cause of socially desirable responding as an interaction between the evaluative content of the item and enhancement motivation in the rater. Study 2 introduced a possible cure; evaluative neutralization of items. To test the feasibility of the method lay psychometricians (undergraduates) reformulated existing personality test items according to written instructions. The new items were indeed lower in social desirability while essentially retaining the five factor structure and reliability of the inventory. We conclude that although neutralization is no miracle cure, it is simple and has beneficial effects.
