Categorization of above and below spatial relations by tufted capuchin monkeys (Cebus apella)

Using a matching-to-sample procedure, the researchers investigated tufted capuchins' (Cebus apella) ability to form categorical representations of above and below spatial relations. In Experiment 1, 5 capuchins correctly matched bar-dot stimuli on the basis of the relative above and below location of their constituent elements. The monkeys showed a positive transfer of performance both when the bar-dot distance in the two comparison stimuli differed from that of the sample and when the actual location of the matching stimulus and the nonmatching stimulus on the apparatus was modified. In Experiment 2, the researchers systematically changed the shapes of the located object (the dot) or the reference object (the horizontal bar). These manipulations did not affect the monkeys' performance. Overall, the data suggest that capuchins can form abstract, conceptual-like representations for above and below spatial relations.     

Spontaneous imagined contact and intergroup relations: Quality matters

While research on experimental interventions that aim to improve outgroup attitudes via contact imagery grows, it is important to examine if contact imagery that occurs in spontaneous, non-experimentally controlled conditions drives attitudes, and in what direction. To answer this, we constructed and validated a spontaneous imagined intergroup contact scale (SIICS) that differentiates between frequency, quality and elaboration of the spontaneous imagery of outgroups. In three correlational studies (N_Portugal = 305, N_{United Kingdom} = 185, N_Italy = 276), we tested the role of spontaneous imagined contact frequency, quality and elaboration in predicting attitudes and social distance (Studies 1–3) and intended behaviour (Study 3) toward immigrant groups. Results demonstrated that spontaneous imagined contact quality consistently predicted key outcome variables above and beyond the other two dimensions. Importantly, the effects were significant while controlling for other potent forms of direct and indirect contact. Implications of the findings for theory and practice are discussed.     

Attributions for social failure and adolescent aggression

In the present study, 119 high school boys and 79 institutionalized delinquent boys of the same age range were assessed on their own aggressive behavior and on their tendencies to attribute social failure to controllable, external, stable causes, anticipate a hostile affective response, and endorse aggressive behavioral responses to by pothetical social situations. While the two populations of boys did not differ detectably in their attributional tendencies, the relations between an individual's aggressiveness and an individual's attributions differed considerably across the two populations. In particular, among deliquent but not among delinquent but not among nondelinquent boys, the tendency to attribute one's social failures to stable and controllable causes predicted stronger hostile emotional responses to failure and a tendency to endorse physically aggressive responses following such failure. These hostile emotional responses to failure and this preference for a physically aggressive response, in turn, predicted greater actual aggression within the population of delinquent boys. Neither of these links could be demonstrated for nondelinquent boys. However, in the nondelinquent sample, attributing social failure to external and controllable causes predicted endorsement of aggressive responses only indirectly through increased hostile affect. It was concluded that the specific relations between cognitive and affective responses to social failure may be a contributing factor to the serious physical aggression displayed by some delinquents and to the less serious aggression of nondelinquents. © 1993 Wiley-Liss, Inc.     

Using Motivational Monitoring to Evaluate the Efficacy of Self-disclosure and Self-involving Interventions

Self-disclosures and self-interventions are generally considered useful, although their role remains controversial. This is mainly due to the heterogeneity of research findings on this topic, characterized by the lack of a clear definition of self-disclosure and of systematic and effective methods to evaluate the short- and long-term effects of such interventions. To clarify the concept of self-disclosure, it is essential to understand whether its definition comprehends different interventions, which may have different effects. An accurate and reliable evaluation of such effects may allow clinicians and researchers to differentiate among different kinds of self-disclosures. In this theoretical article, we propose a method to evaluate the clinical efficacy of self-disclosures interventions. This method is based upon the monitoring of motivational systems (Liotti, 2005), which allows therapists to assess the cooperative attunement between patient and therapist in real-time. Our central assumption is that the evaluation of the cooperative attunement between patient and therapist, as well as the patient’s metacognitive functioning, is primary to assess the use of clinical interventions. Indeed, these factors – either acting on their own or synergistically – are the mark, the essence, and the reflection of the therapeutic alliance, which is the strongest predictor of treatment’s outcome.

     

Frontal theta activation associated with error detection in toddlers: influence of familial socioeconomic status

Error detection is one of the functions of the executive attention network, a brain system involved in executive control that includes the anterior cingulate cortex and other prefrontal regions. Despite the key role of this function in a wide range of life outcomes, very limited research has examined the early development of the network and whether its functional efficacy is related to environmental factors. Electrophysiological studies with adults have shown oscillatory activity in theta (4–7 Hz) range arising from medial frontal cortex that follows the detection of self‐committed or observed errors. In the current study, we designed a novel experimental procedure that involved a familiarization phase with simple three‐pieces puzzles followed by an experimental phase in which toddlers observed the puzzles being formed either correctly or incorrectly. Observation of incorrect configurations produced increased potentials in midline channels and greater power theta activity for both toddlers (n = 56) and adults (n = 14). In addition, socioeconomic status of the family in general, and parental education in particular, contributed to individual differences in the amplitude of the error‐related signal and associated theta power in toddlers, indicating that children raised in lower SES families show poorer activation of the executive attention network. These data demonstrate the influence of environmental factors at the earliest stages of development of the executive attention network. Importantly, the results show that error‐detection EEG signals can be used as neural markers of the initial development of executive attention, which can be of great help for the early detection of risk for developmental disorders involving deficits in this function.     

Exploring the Role of Religiosity and Spirituality in Amniocentesis Decision-Making Among Latinas

Given the complex array of emotional and medical issues that may arise when making a decision about amniocentesis, women may find that their spiritual and/or religious beliefs can comfort and assist their decision-making process. Prior research has suggested that Latinas’ spiritual and/or religious beliefs directly influence their amniocentesis decision. A more intimate look into whether Latinas utilize their beliefs during amniocentesis decision-making may provide an opportunity to better understand their experience. The overall goal of this study was to describe the role structured religion and spirituality plays in Latinas’ daily lives and to evaluate how religiosity and spirituality influences health care decisions, specifically in prenatal diagnosis. Semi-structured interviews were conducted with eleven women who were invited to describe their religious beliefs and thoughts while considering the option of amniocentesis. All participants acknowledged the influence of religious and/or spiritual beliefs in their everyday lives. Although the women sought comfort and found validation in their beliefs and in their faith in God’s will during their amniocentesis decision-making process, results suggest the risk of procedure-related complications played more of a concrete role than their beliefs.     

A General Population Twin Study of Conduct Problems and the Auditory P300 Waveform

Reduced amplitude of the P300 event-related potential has been consistently associated with a variety of externalising problems, including conduct disorder. The few available genetically-informative studies of these relationships, however, were conducted among adolescents/adults (i.e., at an age when conduct disorder has typically already become manifest). Among 200 general population twins with a mean age of 9 years (range 6–14 years), we studied the relationship between the P300 waveform elicited by an auditory oddball task and the DSM-oriented conduct problems scale of the Child Behavior Checklist 6–18. Conduct problems scores were negatively and significantly correlated (r?=??0.19, p?=?0.01) with P300 amplitude; correlations between P300 amplitude and the other DSM-oriented Child Behavior Checklist scales were non-significant, except for oppositional defiant problems (p?=?0.01). We found moderate heritability estimates for both P300 amplitude (0.58, CI:0.37;0.73) and conduct problems (0.52, CI:0.25;0.70). Bivariate twin analyses indicated that the covariation between these two phenotypes can be explained by additive genetic factors only, with a genetic correlation of ?0.33. An association between reduced P300 amplitude and conduct problems can be substantiated already in childhood, at an age that precedes the most typical onset of conduct disorder. This relationship appears to be genetic in nature. Reduced P300 amplitude can represent a valuable marker for conduct problems, and can contribute to the early identification of children at high-risk for conduct disorder.     

A Pilot Randomized Trial of Community-Based Parent Training for Immigrant Latina Mothers

This paper reports on the development and piloting of the Madres a Madres (Mothers to Mothers) program, a new, community-based parent training program designed for immigrant Latina mothers and their children. Promotoras, or female community health workers of Latina background, delivered the program in a home visitation format. A total of 194 mothers and 194 focal children (87 male, 107 female) ages 7–12 were randomized to the intervention (113 mother–child dyads) or wait-list control condition (81 mother–child dyads) over the study period. Outcomes of interest were mother-reported parenting skills, broad family functioning, and child externalizing and internalizing behaviors. Data collection occurred at pretest, 3-month posttest, and 9-month follow-up periods. Multilevel growth models revealed increases in intervention mothers’ reported parenting skills, family support, and family organization, and reductions in child internalizing behavior from pretest to follow-up, relative to the control condition. Outcomes did not vary by focal child age, gender, nativity status, or mother acculturative status (years in the United States). Findings are discussed in the context of future directions for research on the Madres a Madres program and on the implementation and dissemination of empirically-supported parent training practices to culturally diverse families.
