Functional connectivity abnormalities during contextual processing in schizophrenia and in Parkinson’s disease

Functional connectivity was evaluated in patients with schizophrenia (SC) and in patients with Parkinson’s disease (PD) during the performance of a local contextual processing paradigm, to investigate the proposition that functional disconnection is involved with contextual processing deficits in these populations. To this end, we utilized event-related EEG signals, synchronization likelihood and graph theoretical analysis. Local context was defined as the occurrence of a predictive sequence of stimuli before the presentation of a target event. In the SC patients, we observed a decrease in path length (L) in the beta band, for the predictive sequence and for predicted and random targets, compared with controls. These abnormalities were associated with weaker frontal-temporal-parietal connections. In the PD patients we found longer L (theta band) for predicted targets, and higher cluster coefficients for both the predictive sequence (theta band) and predicted targets (alpha and theta bands), compared with controls. Detection of predicted targets was associated with weaker frontal-parietal connections in PD. No group differences were found for randomized standard stimuli in both SC and PD patients. These findings provide evidence of task-specific functional connectivity abnormalities within frontal networks during local contextual processing.     

What Does it Mean to Notice my Students’ Ideas in Science Today?: An Investigation of Elementary Teachers’ Practice of Noticing their Students’ Thinking in Science

Abstract

Efforts toward improving K-12 science education emphasize teachers noticing students’ thinking as they engage in disciplinary practices and reasoning. This noticing requires specialized teacher knowledge and skills as it involves attending to students’ ideas, as well as making sense of and responding to those ideas so that the disciplinary substance in them is recognized, made explicit, and supported. This study investigates three elementary teachers’ in-the-moment noticing of students’ ideas while teaching science and their thinking about what it means to engage in this teaching practice. Results indicate that teachers notice many different kinds of student science ideas, and also that teachers have different ways of thinking about which student ideas are substantive during a science lesson. This research contributes to our theoretical understanding of the nature of teacher noticing in science. Noticing students’ science ideas involves not only the presence of ideas and the ability to notice them, but also a teacher’s understanding of this teaching practice in the moment.     

Ethical Issues in Psychologists' Professional Practice: Agreement Over Problematic Professional Behaviors Among Spanish Psychologists

A sample of 703 Spanish psychologists completed an online survey containing 114 behaviors related to professional practice in different areas. The aim of the study was to learn which professional behaviors create ethical dilemmas most often for psychologists and how they respond to these issues. Findings suggest that psychologists who have actually faced a particular dilemma are less strict on judging the inappropriateness of a possible ethical transgression than those psychologists who have not experienced it. Also, four clusters can be identified according to the attitude of respondents toward the dilemmas, namely “rejection,” “aprioristic,” “utilitarian,” and “no conflict.”     

Monitoring the source monitoring

The hypothesis that the retrieval of correct source memory cues, those leading to a correct source attribution, increases confidence, whereas the retrieval of incorrect source memory cues, those leading to a source misattribution, decreases confidence was tested. Four predictions were derived from this hypothesis: (1) confidence should be higher for correct than incorrect source attribution except; (2) when no source cues are retrieved; (3) only the source misattributions inferred from the retrieval of incorrect source cues will be rated with low confidence; and (4) the number of source cues retrieved, either correct or incorrect, will affect the confidence in the source attributions. To test these predictions, participants read two narratives from two witnesses to a bank robbery, a customer and a teller. Then, participants completed a source monitoring test with four alternatives, customer, teller, both, or neither, and rated their confidence in their source attribution. Results supported the first three predictions, but they also suggested that the number of correct source monitoring cues retrieved did not play a role in the monitoring of the accuracy of the source attributions. Attributions made from the recovery of incorrect source cues could be tagged as dubious or uncertain, thus leading to lowered confidence irrespective of the number of incorrect source cues or whether another correct source cue was also recovered. This research has potential applications for eyewitness memory because it shows that confidence can be an indicator of the accuracy of a source attribution.     

Optimism predicting employees' creativity: The mediating role of positive affect and the positivity ratio

We examine how optimism predicts creativity both directly and through the mediating role of positive affect and the positivity ratio (the ratio between the frequency of positive and negative affective states). Five hundred and ninety five employees reported their positive and negative affect, as well as their optimism. Their creativity was reported by supervisors. The main findings are the following: (1) optimism predicts creativity both directly and through the mediating role of positive affect and the positivity ratio; (2) the relationship between the positivity ratio and creativity is curvilinear, in such a way that an “excessive” ratio is detrimental to creativity. The findings stress the relevance of optimism both for individuals and organizations, and suggest that examining positivity ratios is fruitful in the creativity domain, as it has been in other domains, and that negative affect should not be viewed simply as an obstacle when studying employees' creativity.     

Retail employees' self-efficacy and hope predicting their positive affect and creativity

The study shows how retail employees' self-efficacy and hope predict their creativity, both directly and through the mediating role of positive affect. Five hundred and seven retail employees reported their hope, self-efficacy, and positive affect, their supervisors reporting their creativity. Three main findings are: (1) hope and self-efficacy predict creativity; (2) positive affect also predicts creativity; (3) positive affect partially mediates the relationship between both dimensions of positive psychological capital (self-efficacy and hope), and creativity. The study suggests that retail organizations may foster employees' creativity by encouraging conditions that cultivate employees' hope and self-efficacy, as well as their positive affect.     

Unusual but sound minds: Mental health indicators in spiritual individuals

Previous research has linked certain types of modern spirituality, including New Age and Pagan, with either benign schizotypy or insecure attachment. While the first view emphasizes a positive aspect of spiritual believers’ mental health (benign schizotypy), the second view emphasizes a negative aspect, namely the unhealthy emotional compensation associated with an insecure attachment style. This study addresses these two conflicting views by comparing a sample of modern spiritual individuals (N = 114) with a contrast group of traditional religious believers (N = 86). Measures of schizotypy and attachment style were combined with mental health scales of anxiety and depression. We further assessed death anxiety to determine whether modern spiritual beliefs fulfilled a similar function as traditional religious beliefs in the reduction of existential threat. Our results support a psychological contiguity between traditional and modern spiritual believers and reinforce the need to de‐stigmatize spiritual ideas and experiences. Using hierarchical regression, we showed that unusual experiences and ideas are the major predictor of engagement in modern spiritual practices. Anxiety, depression variables, and insecure attachment were not significant predictors of spirituality or correlated with them; on the other hand, the results show that spiritual believers report high social support satisfaction and this variable predicts involvement in modern spirituality. Further, spiritual practices were negatively correlated with and negatively predicted by death anxiety scores. Overall, the results strengthen the association between modern spirituality, good mental health, and general well‐being.     

Context and Culture: The Initial Clinical Interview with the Latina/o Client

Changing social demographics require that psychotherapists and mental health delivery systems become accountable for developing attitudes and skills for working multiculturally. This article immerses the reader in contextual and cultural principles for establishing an initial therapeutic relationship with Latinas/os. These contextual and cultural principles also can be implemented across any theoretical orientation or clinical interview structure psychotherapists employ. This article also reports on data from a subset of participants (n = 27) that self-identified as bilingual, bicultural, and highly culturally competent from a larger mixed-methods study of 89 Latina/o therapists. The results support the utility of personalismo, respeto, charlar (small talk), language and education, and self-disclosure in building respectful relationships with, and in conducting the initial interview with Latina/o clients. These findings are highly consistent with the common factors literature and lend further support to the proposition that the therapeutic relationship serves as the base for therapeutic interventions across all cultures.     

Deconfounding the Effects of Local Element Spatial Heterogeneity and Sparsity on Processing Dominance

Black and White American college students were compared to determine how daily hassles, coping strategies, and social support related to depression. Although the mean intensity of hassles did not differ, Black students reported a higher frequency of hassles. Cumulative severity of hassles, defined in terms of both intensity and frequency was therefore higher for Black students. White students perceived more support from friends than from family, but the opposite held for Black students. Mean scores on type of coping (active problem solving, seeking social support, or avoidance) were similar, as were the reported levels of depression. Hierarchical multiple regression showed that the severity of hassles was directly related to depression for both groups. Race did not interact with any index of social support, except perceived family support, which was related to lower depression among Black students. There was no support for the notion that social support serves as a buffer against depression.
