Increased saccadic rate during smooth pursuit eye movements in patients at Ultra High Risk for developing a psychosis

Abnormalities in eye tracking are consistently observed in schizophrenia patients and their relatives and have been proposed as an endophenotype of the disease. The aim of this study was to investigate the performance of patients at Ultra High Risk (UHR) for developing psychosis on a task of smooth pursuit eye movement (SPEM). Forty-six UHR patients and twenty-eight age and education matched controls were assessed with a task of SPEM and psychiatric questionnaires. Our results showed that both the corrective and non-corrective saccadic rates during pursuit were higher in the UHR group. There were however no differences in smooth pursuit gain between the two groups. The saccadic rate was related to positive UHR symptoms. Our findings indicate that abnormalities in SPEM are already present in UHR patients, prior to a first psychotic episode. These abnormalities occur only in the saccadic system.     

Impaired emotion recognition in music in Parkinson’s disease

Music has the potential to evoke strong emotions and plays a significant role in the lives of many people. Music might therefore be an ideal medium to assess emotion recognition. We investigated emotion recognition in music in 20 patients with idiopathic Parkinson’s disease (PD) and 20 matched healthy volunteers. The role of cognitive dysfunction and other disease characteristics in emotion recognition was also evaluated.     

Mimicking disliked others: Effects of a priori liking on the mimicry‐liking link

The sharing of bodily states elicits in mimicker and mimickee corresponding conceptualisations, which facilitates liking. There are many studies showing the relatedness of mimicry and liking. However, the mimicry‐liking link has not been investigated under conditions in which the mimickee is liked or disliked a priori. In two studies, we examined moderating effects of a priori liking on the mimicry‐liking link. Liking was measured via self‐report measures (Studies 1 and 2) and behavioural measures using a virtual environment technology (Study 2). Results showed that when participants intentionally mimicked a disliked person, liking for that person was not improved, whereas when participants mimicked a liked person, liking for that person increased. These effects were shown to be mediated by affiliation. These studies not only provided further evidence of a link between mimicry and liking, but also demonstrated that this relationship is moderated by a priori liking.

Feeling of doing in obsessive–compulsive checking

Research on self-agency emphasizes the importance of a comparing mechanism, which scans for a match between anticipated and actual outcomes, in the subjective experience of doing.This study explored the “feeling of doing” in individuals with checking symptoms by examining the mechanism involved in the experienced agency for outcomes that matched expectations. This mechanism was explored using a task in which the subliminal priming of potential action-effects (emulating outcome anticipation) generally enhances people’s feeling of causing these effects when they occur, due to the unconscious perception of a match between primed and observed outcomes. The main result revealed a negative relationship between checking and self-agency for observed outcomes that were primed prior to actions. This suggests that checking individuals fail to grasp the correspondence between actual outcomes of their actions and expected ones. We discuss the possible role of undermined self-agency in checking phenomena and its relationship with cognitive dysfunction.     

Correspondence analysis used complementary to loglinear analysis

Loglinear analysis and correspondence analysis provide us with two different methods for the decomposition of contingency tables. In this paper we will show that there are cases in which these two techniques can be used complementary to each other. More specifically, we will show that often correspondence analysis can be viewed as providing a decomposition of the difference between two matrices, each following a specific loglinear model. Therefore, in these cases the correspondence analysis solution can be interpreted in terms of the difference between these loglinear models. A generalization of correspondence analysis, recently proposed by Escofier, will also be discussed. With this decomposition, which includes classical correspondence analysis as a special case, it is possible to use correspondence analysis complementary to loglinear analysis in more instances than those described for classical correspondence analysis. In this context correspondence analysis is used for the decomposition of the residuals of specific restricted loglinear models.     

Attributional self-presentation and information available to the audience

Public ability attributions of public task performance were investigated as a function of test performance (high or low), task performance (high or low), and the availability of information about test performance to the audience (audience informed or audience not informed). The results were largely in agreement with self-presentation expectations, Ability attributions concerning public task performance addressed to an audience which was not informed about test results, were found to be strongly self-serving, although they were also influenced by consistency of test and task performance. In ability attributions directed at an informed audience, self-serving biases were completely absent, the attributions being in accordance with the consistency or inconsistency of test and task performances.     

Energy Conservation: Two Easy Ways Out1

This study investigated attitude-behavior relationships in the context of energy conservation. Results indicated that general environmental concern is a poor predictor of energy-conservation behaviors. Direct evaluative comparisions of various non-conservationist behaviors with a more conservationist alternative showed a clear relationship with behavioral preference. Non-conservationists, however, evaluated their own behavior only marginally favorably and in some cases clearly unfavorably. This was accompanied by an overestimation of the common occurrence of these behaviors among the general population and by an unwillingness to relate these behaviors to personality characteristics. It is argued that these biases (i.e., considering one's behavior as a habit that is shared by many others) could hinder behavioral change. These findings are discussed in terms of effective public policy on the issue of energy consumption.     

At face value: Categorization goals modulate vigilance for angry faces

The present research demonstrates that the attention bias to angry faces is modulated by how people categorize these faces. Since facial expressions contain psychologically meaningful information for social categorizations (i.e., gender, personality) but not for non-social categorizations (i.e., eye-color), angry facial expression should especially capture attention during social categorization tasks. Indeed, in three studies, participants were slower to name the gender of angry compared to happy or neutral faces, but not their color (blue or green; Study 1) or eye-color (blue or brown; Study 2). Furthermore, when different eye-colors were linked to a personality trait (introversion, extraversion) versus sensitivity to light frequencies (high, low), angry faces only slowed down categorizations when eye-color was indicative of a social characteristic (Study 3). Thus, vigilance for angry facial expressions is contingent on people's categorization goals, supporting the perspective that even basic attentional processes are moderated by social influences.     

Psychopathy as Predictor and Moderator of Multisystemic Therapy Outcomes among Adolescents Treated for Antisocial Behavior

Objective

The aim of the present study was to determine whether psychopathic traits act as a predictor and/or moderator of the effectiveness of Multisystemic Therapy (MST).

Method

The sample included N?=?256 adolescents (188 boys and 68 girls) referred for conduct problems, randomized to MST or Treatment As Usual (TAU). The mean age was 16 years (SD?=?1.31). Assessments were carried out before and immediately after treatment (6 months later). Three psychopathic traits (callous/unemotional traits, narcissism, and impulsiveness) were assessed with parent reports. Adolescents and parents were informants on externalizing problems.

Results

MST was more effective than TAU in decreasing externalizing problems for the “lower callous/unemotional” and “lower narcissism” group, but not for the “high callous/unemotional” and “high narcissism” group (moderators). Impulsiveness was found to predict more post-treatment externalizing problems rated by adolescents (predictor), but not more post-treatment externalizing problems rated by parents.

Conclusions

These findings point out the clinical relevance of adequately assessing psychopathic traits in adolescents referred for treatment of antisocial behaviour, and identifying those adolescents who show high levels of these traits. It is important to tailor MST specifically to meet the needs of juveniles with high levels of callous/unemotional traits and high levels of narcissism to obtain the same level of effectiveness as with juveniles scoring lower on these traits.     

Simultaneously Testing Parenting and Social Cognitions in Children At-Risk for Aggressive Behavior Problems: Sex Differences and Ethnic Similarities

In this cross-sectional study we examined a model in which parenting, child social information processing and self-perception are simultaneously tested as risk factors associated with aggression. Sex and ethnicity were tested as moderators of associations. The sample consisted of 206 4th grade children in the Netherlands. Parents reported on parenting, parent–child relationship, and reactive and proactive aggression whereas children reported on self-perception and social information processing. Results give support for both child social cognitive functioning and parenting as risk factors associated with aggressive behavior: For all children, a positive parent–child relationship was associated with less aggression, negative parenting was related to less positive self-perception, and deficits in social-cognitive functioning were related to aggression. Multigroup analyses showed ethnic similarities and sex differences in patterns of associations, which might suggest personalized tailor-made interventions for aggressive behavior.
