Error monitoring dysfunction across the illness course of schizophrenia

Response monitoring abnormalities have been reported in chronic schizophrenia patients, but it is unknown whether they predate the onset of psychosis, are present in early stages of illness, or are late-developing abnormalities associated with illness progression. Response-synchronized event-related potentials (ERP) recorded during a picture-word matching task yielded error-related negativity (ERN), correct-response negativity (CRN), and error positivity (Pe) from 84 schizophrenia patients (SZ), 48 clinical high risk patients (CHR), and their age-matched healthy controls (HC; n = 110 and 88, respectively). A sub-sample of 35 early illness schizophrenia patients (ESZ) was compared to 93 age-matched HC and the CHR patients (after statistically removing the effects of normal aging). Relative to HC, 1) SZ, ESZ, and CHR had smaller ERNs, and 2) SZ and ESZ had larger CRNs and smaller Pes. Within the SZ, longer illness duration was associated with larger CRNs but was unrelated to ERN or Pe. CHR and ESZ did not differ on ERN or CRN, although Pe was smaller in ESZ than CHR. These results indicate that while ERN, CRN, and Pe abnormalities are present early in the illness, only the ERN abnormality is evident prior to psychosis onset, and only the CRN abnormality appears to worsen progressively over the illness course. Brain regions subserving response monitoring may be compromised early in the illness and possibly during its clinical prodrome.     

The Effect of Family Size on Spanish Simple and Complex Words

This study presents the results of three experiments in which the Family Size (FS) effect is explored. The first experiment is carried out with no prime on simple words. The second and third experiments are carried out with morphological priming on complex words. In the first experiment a facilitatory effect of FS is observed: high FS targets produced faster responses than low FS targets. However, an inhibitory effect of Stem-FS is observed in the second experiment: low Stem-FS targets produced faster responses than high Stem-FS targets. In the third experiment a facilitatory effect is observed when the Affix-FS is manipulated: high Affix-FS targets produced faster responses than low Affix-FS targets. Overall data confirms that the effect of FS plays an important role in lexical access in Spanish. The results also show that the effect of FS is modulated by the lexical nature of the prime (lexical or sublexical) and by the number of candidates activated. Finally, it is suggested that the nonwords employed were decisive in obtaining the results mentioned.     

Diversity is in the eye of the beholder: how concern for the in-group affects perceptions of racial diversity

The reported studies suggest that concern for the in-group motivates Asian Americans and African Americans to define diversity specifically, that is, as entailing both minorities' numerical and hierarchical representation, while motivating White Americans to define diversity broadly, that is, as entailing either minorities' high numerical and/or hierarchical representation in an organization. Studies 2-4 directly assess if a concern for the in-group affects conceptions of diversity by measuring Black and White participants' racial identity centrality, an individual difference measure of the extent to which individuals define themselves according to race. These studies suggest that the tendency to conceive diversity in ways protective of the in-group is especially pronounced among individuals who identify strongly with their racial in-group.     

Career Adapt-Abilities Scale—Brazilian Form: Psychometric properties and relationships to personality

The Career Adapt-Abilities Scale—Brazilian Form (CAASBrazil) consists of four scales which measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. Internal consistency estimates for the subscale and total scores ranged from good to excellent. The factor structure was quite similar to the one computed for combined data from 13 countries. CAASBrazil is similar to the International Form, with the exception of two items that were not included in Brazilian version. Concurrent validity evidence was collected relative to personality factors from the Five-Factor Model of Personality. The relationships between career adaptability and personality factors were as predicted.     

Backward versus forward blocking: evidence for performance-based models of human contingency learning

Two types of theories are usually invoked to account for cue-interaction effects in human-contingency learning, performance-based theories, such as the comparator hypothesis and statistical models, and learning-based theories, such as associative models. Interestingly, the former models predict two important cue-interaction effects, forward and backward blocking, should affect responding in a similar manner, whereas learning-based models predict the effect of forward blocking should be larger than the effect of backward blocking. Previous experiments involved important methodological problems, and results have been contradictory. The present experiment was designed to explore potential asymmetries between forward and backward blocking. Analyses yielded similar effect sizes, thereby favoring the explanation by performance-based models.     

Ambulatory group treatment for cocaine dependent patients combining cognitive behavioral therapy and motivational interviewing

Psychological interventions in cocaine dependent patients have demonstrated efficacy. Remarkable approaches are Contingency Management (CM) and Cognitive Behavioral Therapy (CBT). Lack of treatment adherence is the most important limitation. Motivational Interview (MI) has been shown to be an adherence enhancer. The objective of this study is to evaluate retention and abstinence in a combined CM and CBT group treatment in patients who have reached maintenance stage according to Prochaska and DiClemente's transtheoretical model (1982). Therefore, a longitudinal study was carried out with cocaine dependent patients with or without concomitant mental health disease. A 12-session open group was conducted weekly. Nineteen patients were included (78.9% men, mean age 36.6 years), 95% consumed intranasally and 47% had another psychiatric comorbidity. Treatment retention was 84%. During treatment and the first month of follow-up, all patients remained abstinent whereas at three months, 3 patients relapsed. These data confirm that using combined CM and CBT group therapy in cocaine dependents undergoing maintenance treatment enhances adherence and is effective to achieve abstinence.     

Spanish adaptation of the EAS Temperament Survey for the assessment of child temperament

Better understanding of child temperament is essential, as it may predict subsequent development of psychopathology. Questionnaires which have been adapted to Spanish population include a rather restricted age range. The Emotionality Sociability and Activity (EAS) Temperament Survey has been widely used in child temperament genetic research. A Spanish version of the scale was administered to a sample of 229 mothers and to their children at 18 and 42 months of age. Its psychometric features were examined. Results showed accuracy indices akin to that obtained in prior studies. Findings suggest a three-factor structure for the assessment of temperament.     

Categorisation salience and ingroup bias: The buffering role of a multicultural ideology

The current work sought to test the moderating role of a multicultural ideology on the relationship between categorisation salience and ingroup bias. Accordingly, in one experimental study, we manipulated categorisation salience and the accessibility of a multicultural ideology, and measured intergroup attitudes. Results show that categorisation salience only leads to ingroup bias when a multiculturalism (MC) ideology is not made salient. Thus, MC ideology attenuates the negative effects of categorisation salience on ingroup bias. These results pertain to social psychology in general showing that the cognitive processes should be construed within the framework of ideological contexts.     

Don't leave me: the effect of dependency and emotions in relationship conflict

Two studies examined how the effect of dependency and emotions on the dynamics of relationship conflict differs between men and women. In Study 1, 96 women and 67 men were presented with conflict situations that might occur in their relationship; the probability of aggression, anger, and dependency was measured. Results showed that anger mediated the relationship between dependency and the intention to use aggression, in men, but not in women. In Study 2, 95 women and 65 men wrote about a conflict situation that they had experienced with their partner; loyalty, guilt, and dependency were measured. Results showed that dependency predicted loyalty among women, and that this effect was mediated by guilt.
