INTRODUCTION: Impulsive behaviors are frequently described in brain-damaged patients, including patients with Alzheimer's disease (AD). However, few studies have examined impulsivity changes and associated cognitive impairments in AD and healthy controls. Consequently, the first aim of this study was to compare patients with mild AD and matched controls on four dimensions of impulsivity (urgency, lack of premeditation, lack of perseverance, and sensation seeking) recently highlighted in the literature. The second objective was to examine the association between impulsivity changes and cognitive performances on executive/attentional tasks in mild AD and healthy controls. METHODS: Thirty patients with mild AD and 30 matched controls were administered a battery of tests that assessed executive and attention processes. In addition, informants of each patient and control completed a short questionnaire designed to assess the changes on the four dimensions of impulsivity (Rochat et al., 2008). RESULTS: Patients with mild AD had higher scores than controls on lack of premeditation and lack of perseverance dimensions of impulsivity, whereas the two groups did not differ on urgency and sensation seeking. Furthermore, patients showed significant decreased performances on measures of inhibition of prepotent responses, set-shifting, and working memory, as well as higher variability of reaction times (RTs) than matched controls. Regression analyses computed on the whole sample emphasized that difficulties in inhibition of prepotent responses significantly predicted higher lack of premeditation, and larger variability of RTs and set-shifting difficulties significantly predicted higher lack of perseverance, even when global cognitive functioning, general processing speed, working memory, and age were controlled for. Urgency and sensation seeking were not associated with any variables. CONCLUSIONS: These results provide valuable insight into the nature of brain systems and cognitive processes underlying impulsive behaviors. In addition, they open up interesting prospects for better comprehension of behavioral and psychological symptoms of AD. [less ▲]

This study intends to explore how individual differences in encoding style (i.e. how encoding is implicitly affected by pre-existing schemata, so called an internal style, versus by cues from the outside world, so called an external style) are associated with schizotypal traits and impulsivity expression during adolescence. Moreover, we aim to provide first evidence reliability for the encoding style questionnaire with an adolescent sample. 101 French-speaking community adolescents (Mage=16.06, S.D.age=2.01; 57 girls; primarily Caucasian) participated in a cross-sectional study. The whole sample filled out a battery of self-report questionnaires. Our data supports a positive association between a predominant internal encoding style, the level of positive and disorganized schizotypal traits, and a higher degree of urgency and sensation seeking impulsivity components. On the one hand, these results have clinical implications in the sense that a low level in implicit processing, namely encoding style, is involved in positive and disorganized schizotypal traits as well as in impulsivity. Schizotypal traits and impulsivity are two sets of traits that put youth at risk for the development of severe psychopathological states in adulthood. On the other hand, this research enables an increased understanding of encoding style by providing the first reliable assessment tool for French-speaking adolescents. [less ▲]

BACKGROUND: Football (soccer) is one of the most popular sports in the world, including Europe. It is associated with important betting activities. A common belief, widely spread among those who participate in gambling activities, is that knowledge and expertise on football lead to better prediction skills for match outcomes. If unfounded, however, this belief should be considered as a form of "illusion of control." The aim of this study was to examine whether football experts are better than nonexperts at predicting football match scores. METHODS: Two hundred and fifty-eight persons took part in the study: 21.3% as football experts, 54.3% as laypersons (non-initiated to football), and 24.4% as football amateurs. They predicted the scores of the first 10 matches of the 2008 UEFA European Football Championship. Logistic regressions were carried out to assess the link between the accuracy of the forecasted scores and the expertise of the participants (expert, amateur, layperson), controlling for age and gender. RESULTS: The variables assessed did not predict the accuracy of scoring prognosis (R2 ranged from 1% to 6%). CONCLUSIONS: Expertise, age, and gender did not appear to have an impact on the accuracy of the football match prognoses. Therefore, the belief that football expertise improves betting skills is no more than a cognitive distortion called the "illusion of control." Gamblers may benefit from psychological interventions that target the illusion of control related to their believed links between betting skills and football expertise. Public health policies may need to consider the phenomenon in order to prevent problem gambling related to football betting. [less ▲]

L’impulsivité, généralement considérée comme la tendance à exprimer des comportements spontanés, excessifs et/ou non planifiés, joue un rôle essentiel dans la compréhension de nombreux états psychopathologiques et comportements problématiques. Elle constitue d’ailleurs le critère diagnostique le plus fréquemment mentionné dans le Manuel Diagnostique et Statistique des Troubles Mentaux (DSM). Dans cet article, nous montrons en quoi l’impulsivité constitue un processus « transdiagnostique » impliqué dans le développement et le maintien d’une large gamme de troubles émotionnels. Pour ce faire, et en partant d’un modèle dominant (modèle UPPS de l’impulsivité, Whiteside & Lynam, 2001), nous exposerons en quoi l’impulsivité est un construit multidimensionnel sous-tendu par une pluralité de mécanismes cognitifs, affectifs, et motivationnels. Nous décrirons ensuite les données démontrant que les différentes facettes de l’impulsivité (et les mécanismes associés) prédisent une variété de symptômes psychopathologiques habituellement associés à des diagnostics psychiatriques distincts. Finalement, nous discuterons l’apport d’une telle conception en termes d’évaluation et d’intervention psychologique à travers la présentation d’un cas clinique. [less ▲]

Despite its unambiguous advantages, cellular phone use has been associated with harmful or potentially disturbing behaviors. Problematic use of the mobile phone is considered as an inability to regulate one's use of the mobile phone, which eventually involves negative consequences in daily life (e.g., financial problems). The current article describes what can be considered dysfunctional use of the mobile phone and emphasizes its multifactorial nature. Validated assessment instruments to measure problematic use of the mobile phone are described. The available literature on risk factors for dysfunctional mobile phone use is then reviewed, and a pathways model that integrates the existing literature is proposed. Finally, the assumption is made that dysfunctional use of the mobile phone is part of a spectrum of cyber addictions that encompasses a variety of dysfunctional behaviors and implies involvement in specific online activities (e.g., video games, gambling, social networks, sex-related websites). © 2012 Bentham Science Publishers.

Aim: Impulsivity is a multifaceted construct that has a prominent role in psychiatry and especially in addiction. The objective of the current study is to develop and validate a Spanish version of the short UPPS-P impulsive behavior scale1, which assesses five distinct impulsivity traits (positive urgency, negative urgency, lack of premeditation, lack of perseverance, and sensation seeking). Material and methods: One hundred and eighty-nine participants were included in the study. Confirmatory factor analyses supported the five-factor model of the original scale. Results: The results indicated good internal reliability. External validity was supported by specific relationships with a scale assessing emotion regulation strategies. Conclusion: Accordingly, the short Spanish version of the UPPS-P scale presents good psychometric properties and may be considered a promising instrument for both research and clinical practice. © 2012 Elsevier España, S.L. © 2012 Elsevier España.

The expression of early delusion and hallucination-like symptoms, known as positive schizotypy (PS), holds predictive power for later development of psychotic disorders. However, little is known about the psychological and emotional processes promoting the expression of PS during adolescent development. Our study's objective was to examine the nature of the relationships between adolescent PS and two dimensions previously identified to contribute to adult positive symptoms of psychosis, metacognitive beliefs and anxiety. Using a structural equation modeling design, data from self-report questionnaires measuring anxiety, metacognitive beliefs, and PS were collected from 179 adolescents aged 12 to 19 years. Our results indicate that although metacognitive beliefs significantly influence adolescent PS and anxiety, maladaptive contradictory metacognitive beliefs specifically potentiate positive schizotypal expression in hallucination-prone adolescents. Furthermore, we observe that PS and anxiety entertain reciprocal relationships. These findings suggest that relationships between metacognitive beliefs, anxiety, and PS can already be observed during adolescence. [less ▲]

'Near-miss' outcomes (i.e., unsuccessful outcomes close to the jackpot) have been shown to promote gambling persistence. Although there have been recent advances in understanding the neurobiological responses to gambling near-misses, the psychological mechanisms involved in these events remain unclear. The goal of this study was to explore whether trait-related gambling cognitions (e.g., beliefs that certain skills or rituals may help to win in games of chance) influence behavioural and subjective responses during laboratory gambling. Eighty-four individuals, who gambled at least monthly, performed a simplified slot machine task that delivered win, near-miss, and full-miss outcomes across 30 mandatory trials followed by a persistence phase in extinction. Participants completed the Gambling-Related Cognitions Scale (GRCS; Raylu & Oei, 2004), as well as measures of disordered gambling (South Oaks Gambling Screen [SOGS]; Lesieur & Blume, 1987) and social desirability bias (DS-36; Tournois, Mesnil, & Kop, 2000). Skill-oriented gambling cognitions (illusion of control, fostered by internal factors such as reappraisal of losses, or perceived outcome sequences), but not ritual-oriented gambling cognitions (illusion of control fostered by external factors such as luck or superstitions), predicted higher subjective ratings of desire to play after near-miss outcomes. In contrast, perceived lack of self-control predicted persistence on the slot machine task. These data indicate that the motivational impact of near-miss outcomes is related to specific gambling cognitions pertaining to skill acquisition, supporting the idea that gambling near-misses foster the illusion of control.

The popularity of using the Internet and related applications has grown in European countries in the last two decades. Despite numerous advantages in terms of optimizing communications among individuals and social systems, the use of the Internet may be associated with excessive use and possible Internet addiction. The goals of the current study were to validate a French version of the compulsive Internet use scale (CIUS) and to assess its links with common psychiatric symptoms such as depression (assessed with the Beck depression inventory: BDI), anxiety (assessed with the trait anxiety inventory: STAI) and alcohol misuse (assessed with the alcohol use disorder identification test: AUDIT). The French versions of the CIUS, BDI, STAI and AUDIT were administered to a sample of Internet users. Exploratory and confirmatory analyses, correlation analysis and logistic regression were performed. As previously found with the original version, a one-factor model of the CIUS had good psychometric properties and fit the data well. Excessive use of the Internet was associated with depressive symptoms. [less ▲]

Cue reactivity is essential to the maintenance of addictive disorders. A useful way to study cue reactivity is by means of normative pictures, but few validated tobacco-related pictures are available. This study describes a database of smoking-related pictures: The Geneva Smoking Pictures (GSP). Sixty smoking-related pictures were presented to 91 participants who assessed them according to the classic emotional pictures validation provided by the International Affective Picture System (NIMH Center for the Study of Emotion and Attention, 2002). The pictures were rated according to three dimensions: (1) valence (from positive to negative), (2) emotional arousal (from high arousing to low arousing), and (3) dominance (from submissive to dominant). Participants were also screened with the Fagerstrom Test for Nicotine Dependence. Normative ratings for valence, arousal and dominance of the pictures are provided for the whole sample, as well as separately for dependent (n = 46) and nondependent smokers (n = 45). Arousal and dominance were associated with greater nicotine dependence, but valence ratings were not. The GSP is a normative database providing a large number of stimuli for investigators who are conducting nicotine and tobacco research. [less ▲]

Negative emotions increase self-focused attention, a core feature of depression and anxiety-related disorders. However, the cognitive mechanisms associated with the tendency to self-focus-and, conversely, with the ability to voluntarily disengage attentional resources from the self and direct them towards the external environment-remain poorly understood. Thus, this study aimed to examine whether a specific cognitive control mechanism that directs attention between self-generated thoughts and external information might moderate the relationship between dysphoria and maladaptive self-referential thinking. Results showed that dysphoria increases the frequency of rumination, self-blame, and catastrophising, especially for participants who have more difficulty in switching from self-generated thoughts to information provided by the environment. These results shed new light on the cognitive mechanisms underlying maladaptive self-referential thinking associated with dysphoria. More specifically, this specific cognitive mechanism might play a key role in the maintenance or amplification of a depressed mood. [less ▲]

BACKGROUND: Impulsivity is a multifaceted construct that has a prominent role in psychiatry. Lynam et al (2006) have developed the UPPS-P, a 59-item scale measuring 5 impulsivity components: negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking. The aim of the present study was to validate a short, 20-item French version of the UPPS-P. METHODS: Six hundred fifty participants filled out the short French UPPS-P. A subgroup of participants (n = 145) took part in a follow-up study and completed the scale twice to determine test-retest stability; another subgroup (n = 105) was screened with other questionnaires also to establish external validity. RESULTS: Confirmatory factor analyses supported a hierarchical model comprising 2 higher order factors of urgency (resulting from negative urgency and positive urgency) and lack of conscientiousness (resulting from lack of premeditation and lack of perseverance) as well as a separate factor of sensation seeking. The results indicated good internal consistency and test-retest stability. External validity was supported by relationships with psychopathological symptoms. CONCLUSION: The short French version of the UPPS-P therefore presents good psychometric properties and may be considered a promising instrument for both research and clinical practice. [less ▲]

Numerous studies have shown that problem gambling is characterised by lack of impulse control. However, they have often been conducted without considering the multifaceted nature of impulsivity and related psychological mechanisms. The current study aims to disentangle which impulsivity facets are altered in pathological gambling. Twenty treatment-seeking pathological gamblers (PGs) and 20 matched control participants completed a self-reported questionnaire measuring the various facets of impulsive behaviours (UPPS Impulsive Behaviour Scale), as well as two laboratory tasks assessing inhibitory control (the go-stop task) and tolerance for delayed rewards (single key impulsivity paradigm). Compared with matched controls, PGs exhibited higher urgency, lower premeditation, impairment in prepotent inhibition, and lower tolerance towards delayed rewards. Nevertheless, complementary profile analyses showed that impulsivity-related deficits found in PGs are highly heterogeneous, and that some PGs are neither impulsive in the impulsivity facets assessed nor impaired in the cognitive mechanisms measured. These findings underscore (1) the necessity to disentangle the construct of impulsivity into lower-order components and (2) that further studies should take into account, in addition to impulsivity-related mechanisms, other psychological factors potentially involved in pathological gambling.

BACKGROUND: Several studies have linked massively multiplayer online role-playing games (MMORPGs) with possible problematic usage or internet addiction. AIMS: The main goal of the present study was to assess links between motivations to play in MMORPGs and addictive involvement in such types of games. METHODS: A total of 696 gamers responded to an online survey. RESULTS AND CONCLUSION: Five distinct motivations to play were identified in gamers: achievement, socializing, immersion, relaxing and escaping. Multiple regression analysis revealed that addictive MMORPG use patterns are predicted by achievement, escapism and socializing motives. Gender was also a significant predictor of problematic involvement in MMORPGs. Moreover, addictive MMORPG use positively correlated with the weekly time devoted to playing MMORPGs. [less ▲]

BACKGROUND: Massively Multiplayer Online Role-Playing Games (MMORPGs) are video games in which a large number of players interact with one another in a persistent virtual world. MMORPGs can become problematic and result in negative outcomes in daily living (e.g. loss of control on gaming behaviors, compromised social and individual quality of life). The aim of the present study is to investigate psychological predictors of problematic involvement in MMORPGs. SAMPLING AND METHODS: Fifty-four males who played MMORPGs regularly were recruited in cybercafes and screened using the UPPS Impulsive Behavior Scale (which assesses 4 facets of impulsivity) and the Motivation to Play Online Questionnaire (which assesses personal motives to play online). Negative consequences due to excessive time spent on the Internet were assessed with the Internet Addiction Test. RESULTS: Multiple regression analysis showed that problematic use of MMORPGs is significantly predicted by: (1) high urgency (b = 0.45), and (2) a motivation to play for immersion (b = 0.35). CONCLUSION: This study showed that, for certain individuals (who are characterized by a proneness to act rashly in emotional contexts and motivated to play to be immersed in a virtual world), involvement in MMORPGs can become problematic and engender tangible negative consequences in daily life.
