Grandiose and vulnerable narcissism: a nomological network analysis

Evidence has accrued to suggest that there are 2 distinct dimensions of narcissism, which are often labeled grandiose and vulnerable narcissism. Although individuals high on either of these dimensions interact with others in an antagonistic manner, they differ on other central constructs (e.g., Neuroticism, Extraversion). In the current study, we conducted an exploratory factor analysis of 3 prominent self-report measures of narcissism (N=858) to examine the convergent and discriminant validity of the resultant factors. A 2-factor structure was found, which supported the notion that these scales include content consistent with 2 relatively distinct constructs: grandiose and vulnerable narcissism. We then compared the similarity of the nomological networks of these dimensions in relation to indices of personality, interpersonal behavior, and psychopathology in a sample of undergraduates (n=238). Overall, the nomological networks of vulnerable and grandiose narcissism were unrelated. The current results support the need for a more explicit parsing of the narcissism construct at the level of conceptualization and assessment.     

Delaware School Climate Survey-Student: its factor structure, concurrent validity, and reliability

The Delaware School Climate Survey—Student (DSCS—S) was developed to provide schools with a brief and psychometrically sound student survey for assessing school climate, particularly the dimensions of social support and structure. Confirmatory factor analyses, conducted on a sample of 11,780 students in 85 schools, showed that a bifactor model consisting of five specific factors and one general factor (School Climate) best represented the data. Those five factors are represented in five subscales of the DSCS—S: Teacher-Student Relations, Student-Student Relations, Fairness of Rules, Liking of School, and School Safety. The factor structure was shown to be stable across grade levels (i.e., elementary, middle, and high school), racial-ethnic groups (i.e., Caucasian, African American, and Hispanic), and gender. As evidence of the survey's concurrent validity, scores for each of the five subscales and the total scale correlated moderately, across groups and at the school level, with academic achievement and suspensions and expulsions.     

Sub-Optimal Choice by Pigeons: Failure to Support The Allais Paradox

Pigeons show a preference for an alternative that provides them with discriminative stimuli (sometimes a stimulus that predicts reinforcement and at other times a stimulus that predicts the absence of reinforcement) over an alternative that provides them with nondiscriminative stimuli, even if the nondiscriminative stimulus alternative is associated with 2.5 times as much reinforcement (Stagner & Zentall, 2010). In Experiment 1 we found that the delay to reinforcement associated with the nondiscriminative stimuli could be reduced by almost one half before the pigeons were indifferent between the two alternatives. In Experiment 2 we tested the hypothesis that the preference for the discriminative stimulus alternative resulted from the fact that, like humans, the pigeons were attracted by the stimulus that consistently predicted reinforcement (the Allais paradox). When the probability of reinforcement associated with the discriminative stimulus that predicted reinforcement was reduced from 100% to 80% the pigeons still showed a strong preference for the discriminative stimulus alternative. Thus, under these conditions, the Allais paradox cannot account for the sub-optimal choice behavior shown by pigeons. Instead we propose that sub-optimal choice results from positive contrast between the low expectation of reinforcement associated with the discriminative stimulus alternative and the much higher obtained reinforcement when the stimulus associated with reinforcement appears. We propose that similar processes can account for sub-optimal gambling behavior by humans.     

Development of a metabolic equation for the NuStep recumbent stepper in older adults

The purpose of this study was to develop an accurate metabolic equation for estimating steady-state oxygen consumption (VO2) during submaximal NuStep exercise. Adults (N = 40; M age = 64.0 yr., SD = 6.5; M height = 170.1 cm, SD = 9.1; M weight = 85.7 kg, SD = 19.9) performed two randomized testing sessions. Each session consisted of six stages with combinations of four workloads (1, 3, 5, and 7) at 3 cadences (60, 80, and 100 steps/min.). Multiple regression analysis to predict steady-state VO2 from NuStep workload (W), NuStep steps/min., and subject body mass resulted in the following model (R2 = .73): Steady-state VO2 = 3.5 + 0.016 (W* steps/min.) + 0.092 (steps/min.) - 0.053 (weight). The standard error of the estimate and total error for the prediction of steady-state VO2 under all NuStep workload conditions were 2.3 mL/kg/min. and 2.4 mL/kg/ min., respectively. The standard error of the estimate and total error values are similar to those previously reported in the literature regarding the accuracy of metabolic equations for other exercise modalities. These findings support the use of the equation developed to predict steady-state VO2 for NuStep exercise in older adult clientele.     

How does a vacation from work affect employee health and well-being?

Health and well-being (H&W) improve during vacation. However, it is unclear whether this general development applies to all employees, while also little is known about the underlying processes causing such an improvement. Our research questions were: (1) Does every worker experience a positive effect of vacation on H&W? and (2) Can vacation activities and experiences explain changes in H&W during vacation? In a 7-week longitudinal field study, 96 workers reported their H&W 2 weeks before, during, 1 week, 2 and 4 weeks after a winter sports vacation on 6 indicators (health status, mood, fatigue, tension, energy level and satisfaction). Sixty percent of the sample experienced substantial improvement of H&W during and after vacation. Yet, a small group experienced no (23%) or a negative effect of vacation (17%). Spending limited time on passive activities, pleasure derived from vacation activities, and the absence of negative incidents during vacation explained 38% of the variance in the vacation effect. Although vacation has a positive, longer lasting effect for many, it is not invariably positive for all employees. Choosing especially pleasant vacation activities and avoiding negative incidents as well as passive activities during active vacations apparently contributes to the positive effect of vacation on H&W.     

Trace‐strength and source‐monitoring accounts of accuracy and metacognitive resolution in the misinformation paradigm

Two experiments are reported that investigate the impact of misinformation on memory accuracy and metacognitive resolution. In Experiment 1, participants viewed a series of photographs depicting a crime scene, were exposed to misinformation that contradicted details in the slides, and later took a recognition memory test. For each answer, participants were required to indicate whether they were willing to testify (report) their answer to the Court and to rate confidence. Misinformation impaired memory accuracy but it had no effect on resolution, regardless of whether resolution was indexed with confidence‐rating measures (γ correlation and mean confidence) or a report‐option measure (type‐2 discrimination: d′). In Experiment 2, a similar accuracy‐confidence dissociation was found, and the misinformation effect occurred mostly with fine‐grained responses, suggesting that responding was based on recollected details. We argue that the results support source‐monitoring (SM) accounts of accuracy and resolution rather than accounts based on trace strength. Copyright © 2010 John Wiley & Sons, Ltd.     

Meta-analytic Decisions and Reliability: A Serendipitous Case of Three Independent Telecommuting Meta-analyses

Purpose  

Despite the potential for researcher decisions to negatively impact the reliability of meta-analysis, very few methodological studies have examined this possibility. The present study compared three independent and concurrent telecommuting meta-analyses in order to determine how researcher decisions affected the process and findings of these studies.     

Therapist Use-of-Self Orientations Questionnaire: A Reliability and Validity Study

This article describes the development of the Therapist Use-of-Self Orientation Questionnaire (TUSO-Q), an instrument designed to measure therapists’ use-of-self orientations while working with clients. A total of 373 therapists participated in this study. Exploratory factor analysis in the structural equation modeling context revealed three different therapist use-of-self orientations: Transpersonal, Contextual, and Instrumental. The final model provided an excellent fit to the data. TUSO-Q scores exhibited satisfactory evidence of internal consistency reliability and construct validity. Implications for the scale’s use in clinical research and training are discussed.     

Who benefits from emotional expression? An examination of personality differences among gynaecological cancer patients participating in a randomized controlled emotional disclosure intervention trial

The present study examined the role of neuroticism and extraversion in the effects of written emotional disclosure in patients diagnosed with gynaecological cancer. It was hypothesized that high levels of neuroticism would be associated with an increase in distress after emotional disclosure as mediated by heightened negative affect and avoidance post-disclosure. Conversely, we expected high extraversion to be associated with decreased distress as mediated by heightened positive moods and a decrease in avoidance. Eighty-eight participants were randomly assigned to participate in an expressive writing task versus a control writing task. Distress and avoidance were assessed at baseline and 6 months post-writing. Negative and positive mood were assessed immediately following writing. Multiple regression confirmed that neuroticism but not extraversion moderates the effects of emotional disclosure on distress, however no significant mediating relationships were found.     

Linking sounds to meanings: Infant statistical learning in a natural language

The processes of infant word segmentation and infant word learning have largely been studied separately. However, the ease with which potential word forms are segmented from fluent speech seems likely to influence subsequent mappings between words and their referents. To explore this process, we tested the link between the statistical coherence of sequences presented in fluent speech and infants’ subsequent use of those sequences as labels for novel objects. Notably, the materials were drawn from a natural language unfamiliar to the infants (Italian). The results of three experiments suggest that there is a close relationship between the statistics of the speech stream and subsequent mapping of labels to referents. Mapping was facilitated when the labels contained high transitional probabilities in the forward and/or backward direction (Experiment 1). When no transitional probability information was available (Experiment 2), or when the internal transitional probabilities of the labels were low in both directions (Experiment 3), infants failed to link the labels to their referents. Word learning appears to be strongly influenced by infants’ prior experience with the distribution of sounds that make up words in natural languages.
