Development of a Facebook Addiction Scale

The Bergen Facebook Addiction Scale (BFAS), initially a pool of 18 items, three reflecting each of the six core elements of addiction (salience, mood modification, tolerance, withdrawal, conflict, and relapse), was constructed and administered to 423 students together with several other standardized self-report scales (Addictive Tendencies Scale, Online Sociability Scale, Facebook Attitude Scale, NEO-FFI, BIS/BAS scales, and Sleep questions). That item within each of the six addiction elements with the highest corrected item-total correlation was retained in the final scale. The factor structure of the scale was good (RMSEA = .046, CFI = .99) and coefficient alpha was .83. The 3-week test-retest reliability coefficient was .82. The scores converged with scores for other scales of Facebook activity. Also, they were positively related to Neuroticism and Extraversion, and negatively related to Conscientiousness. High scores on the new scale were associated with delayed bedtimes and rising times.     

Comparison between immigrant and Spanish native-born pathological gambling patients

The study compared clinical, psychopathological, and personality profiles between immigrants and Spanish native-born pathological gambling patients. A total of 1,601 native-born and 133 immigrant patients attending treatment at a specialized hospital unit were administered a battery of questionnaires during clinical assessment. Outcome measures were compared between both groups and the incremental predictive accuracy of the area of origin was examined using a regression model. Native-born Spaniards showed a mean 2.6 yr. greater duration of the disorder, while immigrants scored higher on South Oaks Gambling Screen, frequency of going to casinos, and total money spent (in a single day and/or to recover losses). General psychopathology and personality scores did not differ between the cohorts. However, immigration from Asia had a statistically significantly incremental validity for pathological gambling in South Oaks Gambling Screen scores. Both cohorts shared more similarities than differences in their gambling profiles.     

Psychologie communautaire et psychologie de la santé : l’implication de la recherche psychosociale dans la promotion de la santé

This paper presents the issues and main principles of community psychology and community research as well as associated relationships and viewpoints in terms of health psychology and social psychology. In this perspective, the paper presents the context in which community psychology has emerged and its fundamental principles such as empowerment, community involvement and the ecological model. Using two examples of research in prevention of HIV infection, the paper leads to a greater comprehension of how a particular community-based approach to involve affected populations may be particularly relevant, not only to better understand their beliefs and behaviors but also to try to encourage them to change current behaviors or generate new ones. Research with adolescents involved in promoting condom use illustrates the use of psychosocial models of behavior change through a community approach. A second research focus on medical and psychosocial innovation through the use of non-routine, rapid screening tests for HIV - which are neither carried out nor supervised by medical personnel - aims to highlight the impact of the development of preventive action by directly concerned communities. The article aims to present the innovative methodological and epistemological issues which underpin community research.     

Hair Color and Courtship: Blond Women Received More Courtship Solicitations and Redhead Men Received More Refusals

Previous research on the effect of hair color on people??s evaluation and behavior has revealed discrepant results and the real effect of both male and female hair color on their mating attractiveness has never been tested. In Study 1, female confederates wearing blond, brown, black or red colored wigs were observed while sitting in a nightclub. In Study 2, male confederates wearing different colored wigs asked women in a nightclub for a dance. It was found that blond women were more frequently approached by men whereas blond males did not receive more acceptances to their requests. However, in both conditions, red hair was associated with less attractiveness. Evolutionary theory and differences in mating preferences are used to explain the blond hair effect. Scarcity of red-haired individuals in the population and negative stereotypes associated with red hair are used to explain the negative effect of red hair.     

Development of a work addiction scale

Andreassen, C. S., Griffiths, M. D., Hetland, J. & Pallesen, S. (2012). Development of a work addiction scale. Scandinavian Journal of Psychology 53, 265–272. Research into excessive work has gained increasing attention over the last 20 years. Terms such as “workaholism,”“work addiction” and “excessive work” have been used interchangeably. Given the increase in empirical research, this study presents the development of the Bergen Work Addiction Scale (BWAS), a new psychometrically validated scale for the assessment of work addiction. A pool of 14 items, with two reflecting each of seven core elements of addiction (i.e., salience, mood modification, tolerance, withdrawal, conflict, relapse, and problems) was initially constructed. The items were then administered to two samples, one recruited by a web survey following a television broadcast about workaholism (n = 11,769) and one comprising participants in the second wave of a longitudinal internet‐based survey about working life (n = 368). The items with the highest corrected item‐total correlation from within each of the seven addiction elements were retained in the final scale. The assumed one‐factor solution of the refined seven‐item scale was acceptable (root mean square error of approximation = 0.077, Comparative Fit Index = 0.96, Tucker‐Lewis Index = 0.95) and the internal reliability of the two samples were 0.84 and 0.80, respectively. The scores of the BWAS converged with scores on other workaholism scales, except for a Work Enjoyment subscale. A suggested cut‐off for categorization of workaholics showed good discriminative ability in terms of working hours, leadership position, and subjective health complaints. It is concluded that the BWAS has good psychometric properties.     

Kepler’s optics without hypotheses

This paper argues that Kepler considered his work in optics as part of natural philosophy and that, consequently, he aimed at change within natural philosophy. Back-to-back with John Schuster’s claim that Descartes’ optics should be considered as a natural philosophical appropriation of innovative results in the tradition of practical and mixed mathematics the central claim of my paper is that Kepler’s theory of optical imagery, developed in his Paralipomena ad Vitellionem (1604), was the result of a move similar to Descartes’ by Kepler. My argument consists of three parts. First, Kepler borrowed a geometrical model and experiment of optical imagery from the mélange of mixed and practical mathematics provided in the works of the sixteenth-century mathematicians Ettore Ausonio and Giovanni Battista Della Porta. Second, Kepler criticized the Aristotelian theory of light and he developed his own alternative metaphysics. Third, Kepler used his natural philosophical assumptions about the nature of light to re-interpret the model of image formation taken from Della Porta’s work. Taken together, I portray Kepler’s theory of optical imagery as a natural philosophical appropriation of an innovative model of image formation developed in a sixteenth-century practical and mixed mathematical tradition which was not interested in questioning philosophical assumptions on the nature of light.     

What is an “appropriate” migrant? Impact of the adoption of meritocratic worldviews by potential newcomers on their perceived ability to integrate into a Western society

The acceptance of migrant populations and the definition of an “appropriate” migrant are controversial issues in many countries. The present research focuses on the ideological determinants of how newcomers are evaluated by a host population in a Western country with a strongly rooted meritocratic ideology. We carried out two studies to examine how the expression of meritocratic beliefs by a male potential migrant affects the way he is evaluated by the host population. We measured the host population's perception of the potential migrant's ability to integrate into society, his tendency to adopt the host country's culture, and the general desirability of his world vision for all newcomers. We also noted the host population's judgments of the target's agency and communality. The results showed that a potential newcomer who expresses a strong (vs. weak) belief in a just world (Study 1) or an internal (vs. external) locus of control (Study 2) is evaluated more favorably by the host population. In addition, judgments of the target's integration capacity were only mediated by his perceived agency. We discuss these results in the light of work on the meritocratic ideology and intercultural relations. Copyright © 2012 John Wiley & Sons, Ltd.     

Revisiting backward recall and benchmark memory effects: a reply to Bireta et al. (2010)

When participants are asked to recall lists of items in the reverse order, known as backward recall, several benchmark memory phenomena, such as the word length effect, are abolished (Bireta et al. Memory & Cognition 38:279–291, 2010). Bireta et al. (Memory & Cognition 38:279–291, 2010) suggested that in backward recall, reliance on order retention is increased at the expense of item retention, leading to the abolition of item-based phenomena. In a subsequent study, however, Guérard and Saint-Aubin (in press) showed that four lexical factors known to modulate item retention were unaffected by recall direction. In a series of five experiments, we examined the source of the discrepancy between the two studies. We revisited the effects of phonological similarity, word length, articulatory suppression, and irrelevant speech, using open and closed pools of words in backward and forward recall. The results are unequivocal in showing that none of these effects are influenced by recall direction, suggesting that Bireta et al.’s (Memory & Cognition 38:279–291, 2010) results are the consequence of their particular stimuli.     

A critical evaluation of c as a measure of mnemonic resolution

It is known that visual working memory capacity is limited, but the nature of this limit remains a subject of controversy. Increasingly, two factors are thought to limit visual memory: an object-based limit associated with so-called "slots" models, and an information-based limit associated with resource models. Recently, Barton, Ester, and Awh (2009) introduced a measure of mnemonic resolution, which they dubbed c. We show here that c is critically flawed, and cannot be interpreted as a measure of resolution. We recommend strongly against its use and interpretation, and suggest alternatives approaches for researchers who want to explore mnemonic resolution.
