What works for serious juvenile offenders? A systematic review

This study examines the outcomes of best available empirical research regarding the effectiveness of treatment programs implemented in secure corrections to prevent the recidivism of serious (violent and chronic) juvenile offenders (from 12 to 21 years old). In this review 30 experimental and quasi-experimental studies are analyzed, comparing 2831 juveniles in the treatment groups and 3002 youths for the control groups. The global effect size of these 30 studies in terms of standardized mean difference was d = 0.14 in favour of the treatment groups. This size effect, in terms of "r" coefficient reached the value of 0.07, of low magnitude. The cognitive-behavioral methods of treatment were the most effective in decreasing recidivism. These results report that the rehabilitation programs for serious offenders achieve to reduce the general recidivism in comparison with the control juveniles in approximately seven percent.     

A new apparatus for the study of avoidance conditioning in fishes

An apparatus for the study of avoidance conditioning in fishes is described. The chamber is cylindrical in shape, with shocking electrodes placed above and below the animals, and response is defined as swimming a predetermined distance in either direction along a circumferential path. This apparatus has several advantages over the conventional shuttlebox: (1)There is little constraint on the direction of swimming; (2) the magnitude of response (swimming distance) required for avoidance can easily be varied over a wide range; and (3) variation in the effectiveness of shock with the position of the animal relative to the position of the electrodes is minimized. Some sample data obtained in a free-operant experiment with goldfish are presented.     

Role of anxiety and brooding in specificity of autobiographical recall

Overgeneral schemas and lack of autobiographical memory (AM) specificity about our past experiences can predict mood disturbance. Rumination, functional avoidance and executive processes are the main explanatory variables of such overgenerality. However, in non‐clinical samples, rumination predicts overgenerality most consistently after the induction of dysphoric mood. Anxiety also activates rumination. Furthermore, anxiety predicts memory performance and has effects on mood which are independent of the effects of rumination. So, what might be the role of anxiety in autobiographical memory performance? A sample of 210 voluntary participants reported measures of autobiographical memory, anxiety, rumination (brooding and reflection), functional avoidance and executive functions (semantic and phonetic verbal fluency task). Autobiographical performance (specificity) was negatively associated with brooding and age and positively with phonetic verbal fluency but not with functional avoidance and anxiety. However, anxiety and brooding were positively correlated even after controlling for depression scores. Moreover, using structural equation modeling, anxiety showed a significant indirect effect on autobiographical specificity through brooding rumination. These results suggest a possible association of anxiety with autobiographical recall through brooding rumination.     

The influence of intra‐team conflict on work teams' affective climate: A longitudinal study

We analysed whether relationship conflict mediates the link between task conflict and shared affect at the team level of analysis. Moreover, we tested the hypothesis that the relationship between these two types of intra‐team conflict would be moderated by team members' interaction. The sample was composed of 156 bank branches. Data were gathered at two points in time. Two affect dimensions (tension and enthusiasm) were measured. The results obtained supported our hypotheses. Relationship conflict fully mediated the relationship between task conflict and team affect. Team members' interaction about team issues moderated the relationship between task conflict and relationship conflict, so that when team members' interaction was low, the relationship enhanced, whereas when team members' interaction was high, the relationship weakened.     

Psychology in the Spanish scientific domain through categories cocitation of Journal Citation Report 1990-2005

This work aims to reveal some aspects of the scientific domain of Psychology, in the context of the internationally visible Spanish science in the databases of the Citation Index of The Institute for Scientific Information (ISI), which is represented by a map. We used the methodology of cocitation of thematic categories (JCR-Thompson Scientific), with which we obtained a representation of the scientific activity. The resulting map allowed us to focus on the area of Psychology, whose representation acts as database for the analysis of this discipline in the scientific field with international visibility. This study offers an empirical view of the underlying structure of Spanish Psychology. This is important because most scientists have an intuitive idea of this structure, but this may or may not be real. This way, we present a global vision of the entire discipline that favours its objective analysis as a function of scientists' behaviour as it affects their patterns of communication through the established formal channels.     

The comparator account on thought insertion,alien voices and inner speech: some open questions

Recently, many philosophers and psychologists have claimed that the explanation that grounds both passivity phenomena in the cognitive domain and passivity phenomena that occur with respect to overt actions is, along broad lines, the same. Furthermore, they claim that the best account we have of such phenomena in both scenarios is the “comparator” account. However, there are reasons to doubt whether the comparator model can be exported from the realm of overt actions to the cognitive domain in general. There is a lingering worry concerning such explanations of thought insertion: the "What is compared to what?" problem. Here I examine two ways to tackle this problem. First: thought insertion consists of the misattribution of strings of inner speech which are not attenuated (thought insertion is thus another name for auditory verbal hallucinations). Second: thought insertion is misattributed inner speech which exhibits the same phenomenological characteristics as normal inner speech. After explaining the types of problem that each of these potential solutions faces, I conclude with a set of open questions that the comparator theorist has to tackle.     

Sex differences in discriminative power of volleyball game-related statistics

To identify sex differences in volleyball game-related statistics, the game-related statistics of several World Championships in 2007 (N=132) were analyzed using the software VIS from the International Volleyball Federation. Discriminant analysis was used to identify the game-related statistics which better discriminated performances by sex. Analysis yielded an emphasis on fault serves (SC = -.40), shot spikes (SC = .40), and reception digs (SC = .31). Specific robust numbers represent that considerable variability was evident in the game-related statistics profile, as men's volleyball games were better associated with terminal actions (errors of service), and women's volleyball games were characterized by continuous actions (in defense and attack). These differences may be related to the anthropometric and physiological differences between women and men and their influence on performance profiles.     

The Conditioned Attention Theory and Bifactorial Theory on the Learned Helplessness Syndrome in Appetitive Contexts

The purpose of the present experiment was to explore the theory that deficits in learned helplessness, normally produced by inescapable shock or noncontingent events, are eliminated in subsequent learning discrimination when a combination of exteroceptive cues or feedback stimuli and a predictable stimulus are present. We used 48 pigeons in 6 groups: Group P+C+ training with predictable and controllable events; Group P+U— training with predictable and uncontrollable events; Group U—F training with unpredictable and uncontrollable events and feedback stimulus; Group P+U—F training with predictable and uncontrollable events and feedback stimulus; Group U-RE training with unpredictable, uncontrollable and random events; Group CG did not receive any treatment. Our results demonstrated that a combination of feedback stimuli and predictability was found to be the most effective training against effects of noncontingent events in appetitive contexts.     

Investigating the functioning of a middle category by means of a mixed-measurement model

Researchers have studied whether there are classes of people who differ systematically in the way they respond to polytomous ordered scales with a middle category such as ?. The mixed-partial credit model was fitted to a number of scales of a personality questionnaire. Most of the scales fit better with the use of 2 latent subpopulations. The most consistent difference among the latent classes was related to the functioning of the middle response category. For most of the examinees, the probability of choosing the middle category was very close to zero, but a nonnegligible percentage of people selected this category with much higher probability. The total scores from the 2 subpopulations were incommensurate. Some personality factors contributed to explaining class membership.
