Egos inflating over time: a cross-temporal meta-analysis of the Narcissistic Personality Inventory

ABSTRACT A cross-temporal meta-analysis found that narcissism levels have risen over the generations in 85 samples of American college students who completed the 40-item forced-choice Narcissistic Personality Inventory (NPI) between 1979 and 2006 (total n =16,475). Mean narcissism scores were significantly correlated with year of data collection when weighted by sample size (β=.53, p <.001). Since 1982, NPI scores have increased 0.33 standard deviation. Thus, almost two-thirds of recent college students are above the mean 1979–1985 narcissism score, a 30% increase. The results complement previous studies finding increases in other individualistic traits such as assertiveness, agency, self-esteem, and extraversion.     

Summarizing digital documents: effects of alternate or simultaneous window display

We investigated the effect of window visibility on the computer‐based summarizing of digital documents. Two experiments studied the impact of the simultaneous or alternate display of the windows containing the notepad and source documents. In Experiment 1, the participants were asked to summarize the content of the source documents. In Experiment 2, they were required to copy out sections of the source documents. The results showed that in the alternate condition, the participants performed fewer reading and writing cycles than in the simultaneous condition. Furthermore, in the alternate condition, the writing episodes were both more numerous and more effortful, while quality of the summaries produced using the copying strategy was also affected. These experiments highlight the need for writers to be able to navigate freely and easily between the windows so that they can construct an overall mental representation of their summaries.

Mechanical restraints as positive reinforcers for aggression

Research suggests that, in some cases, mechanical restraints may function as positive reinforcers. In this study, we conducted a functional analysis of severe aggression exhibited by an individual with a history of wearing arm splints. The results of this functional analysis demonstrated that his aggression was maintained by access to the arm splints. Copyright © 2008 John Wiley & Sons, Ltd.     

Risk factors for addictive disorders: a discriminant analysis on 374 addicted and 513 nonpsychiatric participants

Many common risk factors have been described in addictive disorders. Little is known about factors' respective contributions to discrimination of addicted and nonaddicted participants. Two large samples were compared including 513 nonpsychiatric participants and 374 addicted participants meeting the DSM-IV criteria for eating disorders, alcohol, or substance dependence. Twenty-six risk factors were assessed by interview or self-rating scales. A discriminant analysis determined the respective weight of each risk factor. One discriminant function emerged and characterized a depressive dimension. The results suggest that the different risk factors described in addiction could be related to a depressive dimension.     

Bridging identities and disciplines: advances and challenges in understanding multiple identities

The chapters in this volume address the need for a better understanding of the development of intersecting identities over age and context. The chapters provide valuable insights into the development of identities, particularly group identities. They highlight common processes across identities, such as the role of contrast and comparison and the need for individual effort in identity formation. They suggest the value of studying multiple identities in interaction and using interdisciplinary approaches. However, research across identities and disciplines poses challenges for investigators. These challenges can be met and the field advanced by collaborative studies among scholars who represent different disciplines and have studied different identities.     

Impact of mother interactive style on infant affect among babies exposed to alcohol in utero

This study examined the ability of infants prenatally exposed to alcohol to regulate their affect during and after a stressor. Specifically, the Still‐Face Paradigm (Tronick, Als, Adamson, Wise, ' Brazelton, 1978) was used as a stress induction paradigm to assess both mother‐infant interaction and infant self‐regulation. In addition to the mothers' interactive style, the effect of mothers' drinking during and after pregnancy on the infant was explored. Participants were 76 six‐month‐old infants and their mothers. Infant affect and maternal interaction style was coded second‐by‐second for the 6 min of the Still‐Face Paradigm. Results indicated that infants whose mothers made fewer attempts at engaging them during the play portion of the still‐face (e.g., either watched their infant or paid minimal attention to their infant) showed greater negative affect in contrast to infants whose mothers played in an interactive manner. A gender effect was found among female infants. That is, female infants whose mothers drank more during pregnancy showed greater negative affect. The study demonstrates the possibility of early identification of negativity in infants with prenatal alcohol exposure. The impact of mother‐child relationship on emotional regulation of infants prenatally alcohol exposed may be a target of future intervention and further study.

Exaggerated leftward bias in the mental number line of patients with schizophrenia

Several visuo-motor tasks can be used to demonstrate biases towards left hemispace in schizophrenic patients, suggesting a minor right hemineglect. Recent studies in neglect patients used a new number bisection task to highlight a lateralized defect in their visuo-spatial representation of numbers. To test a possible lateralized representational deficit in schizophrenia, we used the number bisection task in 11 schizophrenic patients compared to 11 healthy controls. Participants were required to orally indicate the central number of an interval orally presented. Whereas healthy subjects showed no significant bias, schizophrenic patients presented a significant leftward bias. Therefore, these results suggest an impairment in higher order representations of the number space in patients with schizophrenia, an impairment that is qualitatively similar to the deficit described in neglect patients.     

Adolescents’ Exposure to a Sexualized Media Environment and Their Notions of Women as Sex Objects

This study was designed to investigate whether adolescents’ exposure to a sexualized media environment is associated with stronger beliefs that women are sex objects. More specifically, we studied whether the association between notions of women as sex objects and exposure to sexual content of varied explicitness (i.e., sexually non-explicit, semi-explicit, or explicit) and in different formats (i.e., visual and audio-visual) can be better described as cumulative or as hierarchical. Further, we investigated whether this association was contingent on gender. Based on data from an on-line survey of 745 Dutch adolescents aged 13 to 18, we found that the relationship between exposure to a sexualized media environment and notions of women as sex objects followed a hierarchical pattern: Starting with adolescents’ exposure to sexually semi-explicit content, the statistical significance of the relationship with notions of women as sex objects moved from semi-explicit to explicit sexual content and from visual to audio-visual formats. Exposure to sexually explicit material in on-line movies was the only exposure measure significantly related to beliefs that women are sex objects in the final regression model, in which exposure to other forms of sexual content was controlled. The relationship between exposure to a sexualized media environment and notions of women as sex objects did not differ for girls and boys.
