Acceptability of Prenatal Diagnosis by a Sample of Parents of Sickle Cell Anemia Patients in Cameroon (Sub-Saharan Africa)

Little is known about attitudes of parents of Sickle Cell Anemia patients in sub-Saharan Africa regarding prenatal genetic diagnosis and termination of an affected pregnancy. In this study, structured face-to-face interviews were conducted with a sample of 130 parents in Cameroon that had at least one living child with Sickle Cell Anemia. The majority of participants lived in urban areas (89%), were female (80%), Christian (93%), married (60.2%) in monogamous households (81.1%), were employed (61.7%), and had at least a secondary or tertiary education (82%). The majority of parents accepted the principle of prenatal genetic diagnosis for Sickle Cell Anemia (89.8%) and termination of pregnancy (62.5%). Acceptance of the principle of pregnancy termination increased with unemployment (p < .01) and single marital status (p < .05). The results of this study suggest Cameroonian parents with children affected with Sickle Cell Anemia generally accept the principles of prenatal diagnosis and in some cases termination of a pregnancy affected with Sickle Cell Anemia. Additional findings, policy and practice implications, and research recommendations are presented.     

Recruiting and Selecting Professionals: Context,Qualities and Methods

Evidence based on a survey of professional firms and in-depth interviews with decision-makers responsible for selection examines the most frequently used and valued methods for hiring qualified professional staff in a sample of Scottish accountancy, architecture, law, and surveying practices. The survey suggests an emphasis on personality, work experience and general attributes for senior posts, and that high value is placed on interviews and informal sources of information in assessing these qualities. Firm characteristics and context, particularly size of practice, the role of the partner in the selection process, labour supply, and perception of recruitment difficulties are shown to be related to the type of selection method used. Consistent with the view of selection as a social process, the case study evidence suggests that ‘informality’ may play an important role when partners responsible for selection have long tenure with their firm and when firms experience recruitment difficulties. More generally, informal networks and interview processes may act as effective information and communication vehicles for small and medium-sized professional practices.     

A test of the diffusion model explanation for the worst performance rule using preregistration and blinding

People with higher IQ scores also tend to perform better on elementary cognitive-perceptual tasks, such as deciding quickly whether an arrow points to the left or the right Jensen (2006). The worst performance rule (WPR) finesses this relation by stating that the association between IQ and elementary-task performance is most pronounced when this performance is summarized by people’s slowest responses. Previous research has shown that the WPR can be accounted for in the Ratcliff diffusion model by assuming that the same ability parameter—drift rate—mediates performance in both elementary tasks and higher-level cognitive tasks. Here we aim to test four qualitative predictions concerning the WPR and its diffusion model explanation in terms of drift rate. In the first stage, the diffusion model was fit to data from 916 participants completing a perceptual two-choice task; crucially, the fitting happened after randomly shuffling the key variable, i.e., each participant’s score on a working memory capacity test. In the second stage, after all modeling decisions were made, the key variable was unshuffled and the adequacy of the predictions was evaluated by means of confirmatory Bayesian hypothesis tests. By temporarily withholding the mapping of the key predictor, we retain flexibility for proper modeling of the data (e.g., outlier exclusion) while preventing biases from unduly influencing the results. Our results provide evidence against the WPR and suggest that it may be less robust and less ubiquitous than is commonly believed.     

Family-level impact of the CHAMP Family Program: a community collaborative effort to support urban families and reduce youth HIV risk exposure

This article presents family-level results from an ongoing study examining the impact of the CHAMP (Chicago HIV prevention and Adolescent Mental health Project) Family Program, a family-based HIV preventative intervention meant to reduce the amount of time spent in situations of sexual possibility and delay initiation of sexual activity for urban youth in the 4th and 5th grades living in neighborhoods with high rates of HIV infection. The CHAMP Family Program has been developed, delivered, and overseen by a collaborative partnership, consisting of community parents, school staff, community-based agency representatives, and university-based researchers. Design of the program was informed by input from this collaborative partnership, child developmental theory of sexual risk, and empirical data gathered from the targeted community. This article presents findings that suggest CHAMP Family Program impact on family communication, family decision-making, and family-level influences hypothesized to be related to later adolescent HIV risk. Implications for future family-based HIV prevention research are discussed here.     

Mood-congruent free recall bias in anxious individuals is not a consequence of response bias

The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias.     

Attachment security and intergroup contact

The contact hypothesis suggests that the interaction between members of different groups decreases prejudice. Moderators and mediators shaping this link have been investigated. However, research about the factors that facilitate contact is not frequent. This article examines secure attachment as an antecedent of contact. Three studies provide information about various aspects of the relationship between secure attachment and contact: security is positively associated with (a) intergroup contact, which in turn is related to reduced prejudice (Study 1); (b) implicit approach tendencies toward the outgroup (Study 2); and, once again, (c) with contact through the indirect effect of openness to exploration (Study 3). In the discussion, we recommend priming both secure and insecure schemas to investigate their unique effects on intergroup contact.     

Individuals with intellectual and developmental disabilities: Do educators assign them a fully human status?

The present research investigates the humanity attributions to individuals with intellectual and developmental disabilities (IDD). In three studies, professional educators, who worked in day‐care or community centers, were examined. Humanity attributions were assessed using emotion‐based and trait‐based measures. As expected, individuals with IDD were denied a fully human status: they were perceived as having more non‐uniquely than uniquely human attributes. Furthermore, a lower human status was assigned to individuals with IDD in relation to educators. We also discovered that humanity attributions, but not attitudes, were related to approach/avoidance responses. Altogether, findings show the importance of considering humanity perceptions in the study of social relationships of individuals with IDD. Dehumanizing perceptions can explain the differential treatment these individuals face in various social settings.     

Bayesian inference for psychology,part III: Parameter estimation in nonstandard models

We demonstrate the use of three popular Bayesian software packages that enable researchers to estimate parameters in a broad class of models that are commonly used in psychological research. We focus on WinBUGS, JAGS, and Stan, and show how they can be interfaced from R and MATLAB. We illustrate the use of the packages through two fully worked examples; the examples involve a simple univariate linear regression and fitting a multinomial processing tree model to data from a classic false-memory experiment. We conclude with a comparison of the strengths and weaknesses of the packages. Our example code, data, and this text are available via https://osf.io/ucmaz/.     

Longitudinal effects of contact on intergroup relations: The role of majority and minority group membership and intergroup emotions

A field study was conducted in the Italian context to examine the longitudinal effects of contact on improved intergroup relations, and to test whether the effects were different for majority and minority group members. Furthermore, we examined the processes underlying contact effects. Participants were 68 Italian (majority) and 31 immigrant (minority) secondary school students, who completed a questionnaire at two time points. The results of regression analyses showed that, consistent with the contact hypothesis (Allport, 1954 ), quantity and quality of contact longitudinally improved outgroup evaluation and increased the attribution of positive stereotypes to the outgroup; the reverse paths were non‐significant. Notably, whereas quantity of contact improved intergroup attitudes and stereotypes for both majority and minority participants, quality of contact had reliable effects only for the majority group. Intergroup anxiety and empathy mediated the longitudinal effects of quantity of contact for both Italians and immigrants; the cross‐lagged effects of contact quality on criterion variables for the Italian group were mediated by intergroup empathy. The theoretical and practical implications of findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.
