Filler items and social desirability in Rotter's locus of control scale

Three experiments were conducted to determine whether the use of filler items in Rotter's I-E scale fulfills its stated objective of obscuring the purpose of the scale. Subjects were undergraduate psychology students. Experiment 1 compared the effects of filler items and sex of subject on 145 subjects I-E scores. Experiment 2 examined effects of filler items and sex on I-E responses of 210 subjects under standard and fake good instructions. Experiment 3 examined subjects' ability to discern the purpose of the I-E scale, with and without the filler items. Filler items did not affect I-E score, impede subjects from faking good, or obscure knowledge of the purpose of the I-E scale. Sex differences occurred in faking good, knowledge and certainty of correctness of knowledge.     

Social desirability scale values of locus of control scale items

Summaiy: Three groups of subjects rated each item in Rotter's I-E Scale for its social desirability value. Social desirability scale values (SDSV) of paired items were compared with one another. Results indicated that paired items are not sufficiently similar in their SDSVs, thus enabling subjects to respond on the basis of social desirability. All three groups rated internal items as being significantly more socially desirable than external items. The correlations between the SDSV ratings of the three groups were highly significant. The results indicate that the scale, as it is currently used, is seriously deficient.     

Self-informant Agreement for Personality and Evaluative Person Descriptors: Comparing Methods for Creating Informant Measures

Little attention typically is paid to the way self-report measures are translated for use in self-informant agreement studies. We studied two possible methods for creating informant measures: (a) the traditional method in which self-report items were translated from the first- to the third-person and (b) an alternative meta-perceptual method in which informants were directed to rate their perception of the targets' self-perception. We hypothesized that the latter method would yield stronger self-informant agreement for evaluative personality dimensions measured by indirect item markers. We studied these methods in a sample of 303 undergraduate friendship dyads. Results revealed mean-level differences between methods, similar self-informant agreement across methods, stronger agreement for Big Five dimensions than for evaluative dimensions, and incremental validity for meta-perceptual informant rating methods. Limited power reduced the interpretability of several sparse acquaintanceship effects. We conclude that traditional informant methods are appropriate for most personality traits, but meta-perceptual methods may be more appropriate when personality questionnaire items reflect indirect indicators of the trait being measured, which is particularly likely for evaluative traits.     

Age and Body Satisfaction Predict Diet Adherence in Adolescents with Inflammatory Bowel Disease

The aim of the current study was to determine whether age and body satisfaction predict dietary adherence in adolescents with Inflammatory Bowel Disease (IBD), and whether older females are less adherent than younger males and females. Forty-four participants aged 10–21 with IBD were recruited. Participants provided informed consent and demographics. Body satisfaction was measured by a questionnaire and a task in which participants selected their current and ideal body image out of silhouettes depicting bodies ranging from underweight to obese. Adherence was measured by marking a 100 mm visual analog scale, the 1-week completion of a dietary log, and a questionnaire evaluating coping strategies used for overcoming obstacles to dietary adherence. Age was related to dietary adherence, with younger children being more likely to adhere. Participants more satisfied with their body reported better dietary adherence. Findings remained consistent across multiple measures of body satisfaction and adherence. Healthcare providers and parents should be informed of these findings in order to improve adherence.     

Are personality questionnaires answered mindlessly?

Langer (1978) suggests that repetitive tasks may induce more automatic or mindless responding. Since many personality questionnaires consist of large numbers of questions of a similar form, a possible implication is that such questionnaires are sometimes completed mindlessly. To test this implication, a questionnaire was presented to 150 subjects which contained (both early and late in the questionnaire) items from the Dominance and Impulsivity subscales of Jackson's (1974) Personality Research Form. These items were separated by, or randomly interspersed with, filler items that were either similar (other subscales of the Personality Research Form) or dissimilar (attitude statements concerning nuclear energy). Item order was counterbalanced. It was hypothesized that the inclusion of dissimilar filler items should inhibit mindless responding to the later items. Change scores comparing late and early items showed a significant effect of the type of filler on the Impulsivity scores. A similar trend on the Dominance subscale was not significant. It is argued that personality research should pay more attention to the nature of the cognitive processes involved in self-rating measures.     

Extraversion,Neuroticism, and Face-Name Learning

Previous research has attempted to relate personality traits to paired-associate learning. We tested name recall as a function of extraversion and neuroticism (as assessed by the Eysenck Personality Inventory) and task difficulty. Face photographs were paired with one of three levels of information: names only (an easy task); names and occupations; or names, occupations, and interests (a difficult task). On the easy and difficult tasks, extraverted subjects recalled more names than did subjects scoring at the median or below on that trait. Contrary to expectations, subjects scoring high on neuroticism recalled more names than did subjects scoring low on that trait. Neither trait was significantly related to recall on the moderately difficult task. There was no interaction between traits for name recall, but there was for interests: Neurotic introverts were significantly impaired at recalling interests, whereas the other subjects recalled interests better than names. These findings thus differ from those of paired-associate learning tasks using words and nonsense syllables.     

Selective processing of masked and unmasked verbal threat material in anxiety: Influence of an immediate acute stressor

Attentional biases for threat were investigated using a computerised version of the emotional Stroop task. The study examined the influence of state and trait anxiety by employing a student sample assigned to high trait anxious (HTA; n=32) or low trait anxious (LTA; n=32) groups on the basis of questionnaire scores, and state anxiety was manipulated within participants through the threat of electric shock. Threatening words that were either unrelated (e.g., cancer, danger) or related to the threat of shock (e.g., electrocute, shock) were presented to participants both within and outside of awareness. In the latter condition a backward masking procedure was used to prevent awareness and exposure thresholds between the target and mask were individually set for each participant. For unmasked trials the HTA group showed significant interference in colour naming for all threat words relative to control words when performing under the threat of shock, but not in the shock safe condition. For the masked trials, despite chance performance in being able to identify the lexical status of the items, HTA participants showed facilitated colour naming for all threat words relative to control items when performing under threat of shock, but this effect was not evident in the shock safe condition. Neither valence of the items nor the threat of shock influenced colour naming latencies in either exposure mode for the LTA group.     

A Rigorous Test of the Fit of the Circumplex Model to Big Five Personality Data: Theoretical and Methodological Issues and Two Large Sample Empirical Tests

Our objective was to apply the rigorous test developed by Browne (1992) to determine whether the circumplex model fits Big Five personality data. This test has yet to be applied to personality data. Another objective was to determine whether blended items explained correlations among the Big Five traits. We used two working adult samples, the Eugene-Springfield Community Sample and the Professional Worker Career Experience Survey. Fit to the circumplex was tested via Browne's (1992) procedure. Circumplexes were graphed to identify items with loadings on multiple traits (blended items), and to determine whether removing these items changed five-factor model (FFM) trait intercorrelations. In both samples, the circumplex structure fit the FFM traits well. Each sample had items with dual-factor loadings (8 items in the first sample, 21 in the second). Removing blended items had little effect on construct-level intercorrelations among FFM traits. We conclude that rigorous tests show that the fit of personality data to the circumplex model is good. This finding means the circumplex model is competitive with the factor model in understanding the organization of personality traits. The circumplex structure also provides a theoretically and empirically sound rationale for evaluating intercorrelations among FFM traits. Even after eliminating blended items, FFM personality traits remained correlated.     

Influence of the spacing of trait information on impressions of likability

Five experiments were conducted in which subjects were shown lists of trait adjectives that supposedly described particular individuals. Each list included both positive and negative traits, with all such traits occurring twice. The second occurrence of a trait followed the first either immediately (massed presentation) or after four other traits intervened (distributed presentation). For a given list, all positive traits received massed presentation and all negative traits were distributed, or vice versa. After list presentation, subjects judged how likable the person described would be. In Experiments 1–3 only, there was also a free recall test for the traits. The free recall test revealed both a spacing effect (distributed items being recalled better than massed) and a bias toward recalling negative traits better than positive. Likability judgments paralleled the recall pattern, with the judgments being more positive when positive traits were distributed (and negative massed), than in the opposite arrangement. Correlations calculated between recall and impressions were mostly nonsignificant, however, suggesting that judgments were not based on the recall of specific traits and that inferences formed at encoding were of primary importance.     

Personality and the derogation of others: Descriptions based on self- and peer report

We examined the tendency to react to failure by derogating others. A situation was constructed to test this reaction among those posited to exhibit this behavior most often—narcissistically inclined individuals. The participants (N=64) consisted of college students screened for pathological personality traits using self-report and peer report measures. Participants completed a two-part lab task and received false feedback indicating that they had been outperformed by fellow participants. Among self-report items, the best predictor of other-derogation was narcissism; among peer-report items, the best predictor items described cold, aloof, and avoidant personality tendencies. Findings are discussed with regard to identifying personality trait–situation–behavior patterns through multiple assessment methods.     

Nice or smart? Task relevance of self-characteristics moderates interpersonal projection

Two studies investigated the impact of trait relevance to a specific task on people's projection of their characteristics onto a cooperative partner. We either measured (Study 1) or manipulated (Study 2) the relevance of a trait to a specific cooperative task. In both studies, participants first rated themselves on a list of traits. Then they imagined completing a cooperative task with an unknown partner. Finally, they rated the partner on the same list of traits. In Study 1, we found partner ratings to be positively influenced by self ratings and the idiosyncratic measure of trait relevance. In Study 2, participants rated the self and the partner on competence and warmth traits while completing an intellectual or a social task. We found partner ratings to be positively influenced by self ratings more on competence than on warmth in the intellectual task, but more on warmth than on competence in the social task. These results suggest that people project onto others in a way that maximizes their chances to succeed in cooperation.     

A pilot study of change in cerebral activity during personality rating by questionnaire and personal computer

The purpose of this study was to examine cerebral blood flow in the frontal cortex area during personality self‐rating tasks. Our two hypotheses were (1) cerebral blood flow varies based on personality rating condition and (2) cerebral blood flow varies based on the personality traits. This experiment measured cerebral blood flow under 3 personal computer rating conditions and 2 questionnaire conditions. Comparing the rating conditions, the results of the t‐test indicated that cerebral blood flow was higher in the questionnaire condition than it was in the personal computer condition. With respect to the Big Five, the result of the correlation coefficient, that is, cerebral blood flow during a personality rating task, changed according to the trait for agreeableness. The results of the analysis of the 5‐cluster on individual differences indicated that certain personality traits were related to the factors that increased or decreased cerebral blood flow. An analysis of variance indicated that openness to experience and Behavioural Activation System‐drive was significant given that participants with high intellectual curiosity were motivated in this experiment, thus, their cerebral blood flow may have increased. The significance of this experiment was that by employing certain performance measures we could examine differences in physical changes based on personality traits.
