Solidarity in STEM: How Gender Composition Affects Women’s Experience in Work Teams

The relationships among the percentage of women in a team and women’s sense of team identification and collective efficacy as well as team performance was examined. We explored these relationships in a sample of student teams conducting a semester-long social science research project within the context of science and technology-focused university. Findings with 95 U.S. college students (43 women) show that women experience higher team identification and collective efficacy as the percent of women teammates increases. Additionally, women’s team identification and collective efficacy mediate the relationship between the percentage of women on the team and overall team performance. Interestingly, the number of men on the team did not influence men’s sense of team identification, collective efficacy, or team performance. This research has implications for team composition. Specifically, when navigating diversity in teams, managers and leaders should aim to build teams that are composed of multiple women versus an approach that divides women up among various teams. In doing so, managers can better secure conditions for the development of positive teamwork experiences and, ultimately, performance.

     

Questionable research practices among Brazilian psychological researchers: Results from a replication study and an international comparison

Research on scientific integrity is growing in psychology, and questionable research practices (QRPs) have received more attention due to its harmful effect on science. By replicating the procedures of previous research, the present study aimed at describing the use of QRPs among Brazilian psychological researchers and to make an international comparison with previous studies in other countries—the US and Italy. Two hundred and thirty-two Brazilian researchers in the field of psychology answered questions related to 10 different QRPs. Brazilian researchers indicated a lower tendency to engage in two QRPs (failing to report all of a study's dependent measures; deciding whether to collect more data after looking to see whether the results were significant) when compared to their Italian and North American counterparts, but indicated a higher tendency to engage in two other QRPs (selectively reporting studies that “worked”; not reporting all of a study's conditions). Most of the sample did not admit integrity conflicts in their own research but indicated that others have integrity problems, as observed in previous studies. Those discrepancies could be attributed to contextual and systemic factors regarding different publication demands among the different nations. Further studies should focus on identifying the antecedents of QRPs.     

Enabling Action: Reflections upon Inclusive Participatory Research on Health with Women with Disabilities in the Philippines

People with disabilities experience health disparities arising from social, environmental, and system-level factors. Evidence from a range of settings suggests women with disabilities have reduced access to health information and experience barriers to screening, prevention, and care services. This results in greater unmet health needs, particularly in relation to sexual and reproductive health. Women with disabilities are also more likely to experience physical and sexual violence than women without disabilities, further undermining their health. Community-based participatory research (CBPR) can generate knowledge and underpin action to address such health disparities and promote health equity. However, the potential and challenges of disability inclusion in CBPR, particularly in contexts of poverty and structural inequality such as those found in low- and middle-income countries, are not well documented. In this paper, we reflect on our experience of implementing and evaluating W-DARE, a three-year program of disability-inclusive CBPR aiming to increase access to sexual and reproductive health and violence-response services for women with disabilities in the Philippines. We discuss strategies for increasing disability inclusion in research and use a framework of reflexive solidarity to consider the uneven distribution of the benefits, costs, and responsibilities for action arising from the W-DARE program.     

Correlates of Happiness Among Older Spanish Institutionalised and Non-Institutionalised Adults

The overall objective of this study was to explore the current (i.e., at the time of the study) and past (i.e., over their lifetimes) happiness of 65-year-old and older men and women who had different personal and socio-demographic characteristics. We also investigated the role of affect balance and life satisfaction as sources of participants’ subjective well-being, as well as the contribution of other psychosocial variables, including self-efficacy, optimism, health and quality of life, stress, social support and leisure, and of socio-demographic conditions. Further, we examined the influence of institutionalisation on happiness and on the aforementioned psychosocial variables. Participants voluntarily completed self-reports regarding all of these variables. Participants’ current happiness (M = 6.6 on a 0–10 scale) was significantly lower than their past happiness (M = 7.7). The happiness of the institutionalised participants did not differ from that of the non-institutionalised participants, although significant differences were found for a number of psychosocial variables. Affect balance and life satisfaction were significant correlates and predictors of current happiness, which was also associated with many psychosocial variables and was further predicted by past happiness, health indicators and some life dimensions assessed as perceived sources of one’s own happiness, such as a sense of autonomy and independence. Our results highlight the importance of establishing both happiness and its correlates to develop interventions aimed at promoting subjective well-being in older people, given that, compared to earlier periods in life, happiness may be reduced in late adulthood.     

Recombinative reading derived from pseudoword instruction in a miniature linguistic system

A miniature linguistic system was used to study acquisition of recombinative symbolic behavior. Three studies evaluated the teaching conditions of conditional discriminations with printed and spoken pseudowords that could potentially generate recombinative reading. Fifty-four college students across all studies learned to match 12 printed pseudowords to 12 spoken pseudowords. Some also matched pictures to the same spoken words. Each two-syllable pseudoword was formed by symbols from an arbitrarily created alphabet composed of four vowels and four consonants. Letters had univocal correspondence with phonemes. Recombinative receptive reading, comprehensive reading, and textual responding to pseudowords were periodically assessed. Experiment 1 (n = 20) showed that recombinative reading increased as the number of trained words composed of the same symbols increased. Experiment 2 (n = 14) showed that overtraining the same two words did not produce recombinative reading for most participants. Experiment 3 (n = 20), in which training with pictures was omitted, showed that elemental control by within-syllable units can develop even when the trained pseudowords are meaningless (not related to pictures). The present results support the utility of the miniature linguistic system methodology for identifying and controlling environmental determinants of rudimentary reading skills.     

The nature of schizotypy among multigenerational multiplex schizophrenia families

Identification of endophenotypes (Gottesman & Gould, 2003; Gottesman & Shields, 1972) that genetically correlate with schizophrenia and are genetically homogeneous is an important strategy for detecting genes that affect schizophrenia risk. Symptoms of schizotypy may familially correlate with schizophrenia; however, there are critical limitations of the current literature concerning this association. The present study examined the genetic architecture and genetic associations between schizotypy and schizophrenia among multigenerational, multiplex schizophrenia families. Genetic schizotypy factor scales were developed that genetically correlated with schizophrenia, although some relations were unexpected in direction suggesting minimization of "psychotic-like" symptoms. These genetic schizotypy factor scales did not genetically correlate with major depressive disorder or substance dependence indicating specificity to schizophrenia. The results highlight the possibility of significant response bias in schizophrenia families, particularly among close relatives, and suggest an important consideration when acquiring self-report information. This is a topic that deserves future study as the origins of this putative bias in relatives are unclear. In addition, the results support the identification of genetic schizotypy factors as a promising technique for maximizing genetic correlation of endophenotypes with schizophrenia.     

How we relate to brands: Psychological and neurophysiological insights into consumer–brand relationships

In three experiments, this research provides new insights into branding by studying the psychological and neurophysiological mechanisms of how consumers relate to their beloved brands. The authors propose that emotional arousal decreases over the brand relationship span, while inclusion of the brand into the self increases over time. Results of experiment 1 indicate greater self-reported emotional arousal for recently formed brand relationships, as well as decreased emotional arousal and increased inclusion of close brands over time. Additionally, the moderating role of usage frequency of the brand brings out an interesting nuance of the way these effects operate. Experiment 2 measures skin conductance responses and reveals increased emotional arousal for recently formed close relationships but not for established close brand relationships, corroborating the results based on self-reported data. In experiment 3, a functional magnetic resonance imaging study reveals an association between established close relationships and activation of the insula, a brain area previously found to be a crucial mechanism in diverse but related psychological phenomena such as urging, addiction, loss aversion, and interpersonal love.     

Development of abbreviated nine-item forms of the Raven's standard progressive matrices test

The Raven's standard progressive matrices (RSPM) is a 60-item test for measuring abstract reasoning, considered a nonverbal estimate of fluid intelligence, and often included in clinical assessment batteries and research on patients with cognitive deficits. The goal was to develop and apply a predictive model approach to reduce the number of items necessary to yield a score equivalent to that derived from the full scale. The approach is based on a Poisson predictive model. A parsimonious subset of items that accurately predicts the total score was sought, as was a second nonoverlapping alternate form for repeated administrations. A split sample was used for model fitting and validation, with cross-validation to verify results. Using nine RSPM items as predictors, correlations of .9836 and .9782 were achieved for the reduced forms and .9063 and .8978 for the validation data. Thus, a 9-item subset of RSPM predicts the total score for the 60-item scale with good accuracy. A comparison of psychometric properties between 9-item forms, a published 30-item form, and the 60-item set is presented. The two 9-item forms provide a 75% administration time savings compared with the 30-item form, while achieving similar item- and test-level characteristics and equal correlations to 60-item based scores.     

Glucocorticoids interact with the noradrenergic arousal system in the nucleus accumbens shell to enhance memory consolidation of both appetitive and aversive taste learning

It is well established that glucocorticoid hormones strengthen the consolidation of long-term memory of emotionally arousing experiences but have little effect on memory of low-arousing experiences. Although both positive and negative emotionally arousing events tend to be well remembered, studies investigating the neural mechanism underlying glucocorticoid-induced memory enhancement focused primarily on negatively motivated training experiences. In the present study we show an involvement of glucocorticoids within the nucleus accumbens (NAc) in enhancing memory consolidation of both an appetitive and aversive form of taste learning. The specific glucocorticoid receptor (GR) agonist RU 28362 (1 or 3ng) administered bilaterally into the NAc shell, but not core, of male Sprague-Dawley rats immediately after an appetitive saccharin drinking experience dose-dependently enhanced 24-h retention of the safe taste, resulting in a facilitated attenuation of neophobia. Similarly, GR agonist infusions given into the NAc shell immediately after pairing of the saccharin taste with a malaise-inducing agent enhanced memory of this negative experience, resulting in an intensified conditioned aversion. Importantly, a suppression of noradrenergic activity within the NAc shell with the β-adrenoceptor antagonist propranolol blocked the facilitating effect of a concurrently administered GR agonist on memory consolidation in both the appetitive and aversive learning task. Thus, these findings indicate that GR activation interacts with the noradrenergic arousal system within the NAc to enhance memory consolidation of emotionally arousing training experiences regardless of valence.     

Perspectives on Marital Love and Satisfaction in Mexican American and Anglo-American Couples

Aspects of intimacy and satisfaction were explored for a volunteer sample of 54 Mexican American (classified as either Hispanic-oriented or bicultural) and 30 Anglo-American married couples. Data were collected by questionnaire through network sampling. Measures included the Acculturation Rating Scale for Mexican Americans, a background inventory, the Love Attitudes Scale, and the Dyadic Adjustment Scale. Ethnic differences occurred for 3 love attitudes and 2 sex attitudes (e.g. Hispanic-oriented respondents were more pragmatic about love and less idealistic about sex). Passionate love was correlated with marital satisfaction for Anglo-Americans and both groups of Mexican Americans. Partner similarity was evident in all 3 groups, and marital satisfaction was best predicted for all groups by passionate love scores. Implications for counseling are discussed.
