The role of urgency and its underlying psychological mechanisms in problematic behaviours

The urgency facet of impulsivity, that is, the tendency to act rashly in response to intense emotional contexts [Cyders, M. A., & Smith, G. T. (2008). Emotion-based dispositions to rash action: positive and negative urgency. Psychological Bulletin, 134, 807-828], has been related to a wide range of maladaptive behaviours. The present study further investigates the role of urgency in problematic behaviours by considering distinct psychological mechanisms that may underlie this component of impulsivity. With this aim, 95 volunteer participants were screened with self-reported questionnaires assessing urgency and three problematic behaviours (compulsive buying, excessive mobile phone use, excessive Internet use). They performed two laboratory tasks: a stop-signal task designed to assess the capacity to inhibit prepotent responses in response to both neutral and emotional stimuli; and the Iowa Gambling Task (IGT) measuring the ability to take into account the future consequences of an action. A poor ability to inhibit prepotent responses in the emotional condition of the stop-signal task was found to predict more disadvantageous choices in the IGT, which ultimately results in higher urgency and more problematic behaviours. These findings shed new light on the construct of urgency, its related psychological mechanisms, and its role in problematic behaviours.     

Requirements for a Democratic Education Organization

What makes a democratic school democratic? This question is answered using the example of the Swiss education system; the focus, however, is not on the usual pedagogic perspective of teaching democracy, but on the democratic organization of the education system. The discussion concentrates on two basic requirements for a democratic education organization: on the one hand, education for all under the equal rights premise calls for the definition of an educational minimum for all students. At the same time, defining this minimum presupposes selection among the students. For part of the students are -- through the use of public funds -- being educated beyond the minimum; a situation which needs to be democratically legitimized. The selection is based on academic performance; as yet, a valuable alternative to this type of selection does not exist. On the other hand, it is essential in a democratic education organization that the authorities put in charge of certain responsibilities are democratically legitimized and controlled. The same applies to newly created authorities, such as principalships or autonomous schools, the introduction of which has been demanded repeatedly for some time now.

     

Regional studies of brain biogenic amines in castrated muricidal and non-muricidal wistar rats

Castrated Wistar rats were isolated for 8 months and their muricidal behavior was investigated. Significantly fewer (35%) of such rats became muricidal (CM) compared to controls. The steady-state levels of 5-HT, 5-HIAA, DA, DOPAC, and NE, as well as the changes in synthesis or utilization rats of 5-HT and DA, were analyzed in 15 brain areas derived from CM rats and non-muricidal (CNM) control subjects. In CM rats, higher 5-HT levels were recorded in 5 areas considered to be involved in muricidal behavior: raphe, amygdala, olfactory tubercles, olfactory bulbs, and striatum. The alterations of serotonergic neurotransmission in castrated muricidal rats differ strikingly from those observed in non-castrated muricidal rats. An increase of 5-HT level and in the 5-HT synthesis index as well as a lower 5-HT utilization index were recorded in the raphe of CM rats. Our data suggest that the decrease of 5-HT levels generally said to be the main alteration in the muricidal rat's brain has to be reconsidered. Increased DA levels were observed in CM rats: raphe (50%), amygdala, olfactory tubercles, striatum, and septum (40%), while DA was decreased in cortical areas. There were slight increases of DA synthesis indices in the septum, olfactory tubercles and striatum with a decreased utilization index in the olfactory tubercles. Few alterations in NE levels were observed in CM rats: a decrease in the olfactory tubercles, superior colliculus, and striatum and an increase in temporal cortex. The monoaminergic alterations correlate with the modulation of muricidal behavior. Some areas (the olfactory tubercles, raphe, striatum, and temporal cortex) seem to be particularly involved. © 1992 Wiley-Liss, Inc.     

Does multitasking mediate the relationships between episodic memory,attention, executive functions and apathetic manifestations in traumatic brain injury?

Apathy is frequently described in patients with traumatic brain injury (TBI); its negative consequences particularly affect functional independence. Among apathetic manifestations, lack of initiative and lack of interest have mainly been associated with cognitive impairments. However, few studies have been conducted to precisely identify the underlying cognitive processes. Our aims were (1) to determine the best predictor of apathy from among several cognitive processes, including episodic memory and attention/executive mechanisms and multitasking, and (2) to examine to what extent multitasking could mediate the relationships between specific cognitive processes and lack of initiative/interest. Seventy participants (34 patients with TBI matched with 36 control participants) were given a questionnaire to assess anxio‐depressive symptoms, four tasks to assess specific cognitive processes, and one task to assess real‐life multitasking. Participants’ relatives completed an apathy questionnaire. Multitasking, as assessed by the number of goals not achieved, was the only significant predictor of apathetic manifestations. In addition, the mediation analyses revealed that multitasking performance mediated the relationships between verbal episodic memory and lack of initiative/interest, whereas executive and attentional functions were only indirectly related to lack of initiative/interest due to their significant impacts on multitasking. These results shed new light on the aetiology of apathetic manifestations in patients with TBI, indicating how specific cognitive deficits are expressed in real‐life multitasking, and consequently, how they may lead to the development and/or maintenance of apathetic manifestations.     

Are human beings free?

This article examines the question of freedom of choice (free-will) in human beings. The process of decision making is analysed and the author presents the conclusion that since this process is determined by the perceptions and interpretations of the person, it cannot be termed free. Applications are drawn to the therapeutic process, specifically in regard to anger and guilt.     

Relationships Between Treatment Attitudes,Psychological Symptoms,Emotional Competence,and Help‐Seeking Intentions

The authors examined whether emotional competence (i.e., awareness, coping strategies) predicted help‐seeking intentions above and beyond previously identified factors (i.e., attitudes and perceived stigma toward professional help, psychological symptom severity) in an undergraduate sample (N = 531). Emotional awareness predicted help‐seeking intentions for personal/emotional problems and suicidal thoughts. Emotional coping strategies predicted help‐seeking intentions for suicidal thoughts and moderated the relationship between symptom severity and help‐seeking intentions for suicidal thoughts. Efforts to increase help‐seeking should address students' emotional competence.     

First psychometric evaluation of a disease-specific questionnaire for children's behavior related to otitis media with effusion

The major goal of the present study is a psychometric analysis of two age-specific questionnaires for the assessment of Otitis Media with Effusion-specific behavior in young children, intended for use in case-finding. In total, 172 children ages 12 to 24 mo. and 121 children ages 24 to 48 mo. were available initially. Caregivers completed the questionnaires on two occasions before tympanostomy tube insertion and once 6 wk. later. Factor analysis of a matrix for 30 items yielded four factors for the younger age group and six factors for a 33-item matrix for the older age group, showing more differentiation of factors in terms of developmental specificity for behavior related to Otitis Media with Effusion. The total internal consistency was .82, and each factor measured different aspects of disease-specific behavior (alpha < or = 0.25) in both questionnaires. Sensitivity to change seemed promising and was significant for the age group 12 to 24 mo. Research with revised questionnaires is recommended, in an ongoing validation process, to create optimal developmental conditions for children with chronic or persistent Otitis Media with Effusion.
