Face detection in complex visual displays: an eye-tracking study with 3- and 6-month-old infants and adults

The ability to detect and prefer a face when embedded in complex visual displays was investigated in 3- and 6-month-old infants, as well as in adults, through a modified version of the visual search paradigm and the recording of eye movements. Participants (N=43) were shown 32 visual displays that comprised a target face among 3 or 5 heterogeneous objects as distractors. Results demonstrated that faces captured and maintained adults' and 6-month-olds' attention, but not 3-month-olds' attention. Overall, the current study contributes to knowledge of the capacity of social stimuli to attract and maintain visual attention over other complex objects in young infants as well as in adults.     

Reducing Competitive Victimhood in Kosovo: The Role of Extended Contact and Common Ingroup Identity

During intractable conflicts, “competitive victimhood” refers to the subjective belief that one's own ingroup has suffered more than the outgroup. Although competitive victimhood is considered an important inhibitor of reconciliation processes, no research has attempted to examine ways of reducing it. The present study aims to fill this gap. Kosovar Albanians students (N = 170) were asked to report their perception of ingroup and outgroup victimhood during the protracted violence between Serbs and Albanians in Kosovo. Our findings revealed that frequent and high‐quality extended contact with outgroup members and identification with a common ingroup reduced competitive victimhood. The effects of extended contact and common ingroup identification were fully mediated by increased perspective taking and trust toward the outgroup, and by decreased outgroup infrahumanization. The implications of these results for restoring fractured intergroup relations are discussed.     

Decision making cognition in primary progressive aphasia

We sought to investigate the decision making profile of Primary Progressive Aphasia (PPA) by assessing patients diagnosed with this disease (n = 10), patients diagnosed with behavioral variant frontotemporal dementia (bvFTD, n = 35), and matched controls (n = 14) using the Iowa Gambling Task, a widely used test that mimics real-life decision making. Participants were also evaluated with a complete neuropsychological battery. Patients with PPA were unable to adopt an advantageous strategy on the IGT, which resulted in a flat performance, different to that exhibited by both controls (who showed advantageous decision making) and bvFTD patients (who showed risk-appetitive behavior). The decision making profile of PPA patients was not associated with performance on language tasks and did not differ between sub-variants of the disease (namely, semantic dementia and progressive nonfluent aphasia). Investigating decision making in PPA is crucial both from a theoretical perspective, as it can shed light about the way in which language interacts with other cognitive functions, as well as a clinical standpoint, as it could lead to a more objective detection of impairments of decision making deficits in this condition.     

Age-Related Change in Shifting Attention Between Global and Local Levels of Hierarchical Stimuli

The focus of this study was the developmental pattern of the ability to shift attention between global and local levels of hierarchical stimuli. Children aged 7 years and 11 years and 21-year-old adults were administered a task (two experiments) that allowed for the examination of 1) the direction of attention to global or local stimulus levels; 2) the susceptibility to interference of the global or local stimulus levels; and 3) the flexibility in directing attention to global or local stimulus levels. The results revealed a global advantage effect that decreased with age when the task required level shifting from trial to trial. The abilities to resist interference and to flexibly shift attention also improved during childhood, but quickly leveled off during adolescence. The ability to shift attention was found to be unrelated to processes contributing to global advantage. The results suggest that the ability to flexibly shift attention to and away from local detail, to provide the most adaptive response, continues to develop during childhood into adulthood.     

A Mobile Colonoscopic Unit for Lynch Syndrome: Trends in Surveillance Uptake and Patient Experiences of Screening in a Developing Country

The Genetic and Endoscopic Surveillance Clinic is an annual outreach service offering accessible colonoscopic surveillance to known families with Lynch syndrome living in remote areas of the Western and Northern Cape Province of South Africa. Unfortunately attendance at this outreach clinic has been declining over several years and fewer than a quarter of participants, attending for surveillance, have been adherent with all their recommended screening appointments. Concerns exist for non-adherent individuals as screening can prevent colorectal cancer by removing the precancerous lesion or enabling the treatment of a malignancy at an early stage. This study explored the experience of surveillance from both the non-adherers’ and adherers’ perspectives and identified unique factors affecting attendance at the outreach clinic. Rates of compliance are calculated for 191 mutation-positive cases of Lynch syndrome, using strict attendance criteria, and compared to figures obtained from self-reported attendance. Non-compliance was under-reported and compliance was exaggerated when basing data on self-reported adherence to recommendations. Specific characteristics of the outreach clinic affecting compliance are identified and recommendations are made to facilitate improvements to the service. These improvements can result in increased compliance with screening regimens and ultimately reduce cancer-related mortality.     

Self-efficacy,Work, and Psychological Outcomes in a Public Service Context

The study examined the prediction of psychological outcomes (conceptualized as psychological well-being and engagement) by general self-efficacy (GSE) and work context (conceptualized as job demands and job resources). The role of GSE as a moderator between work context and psychological outcomes was also examined in a cross-sectional survey of a sample of public sector employees (N = 459: males = 151, females = 273, and age ranging between 25 and 55). Multiple regression analyses showed that job demands and resources and GSE significantly predict both psychological well-being (positive affect, negative affect and satisfaction with life) and engagement (vigour and dedication). GSE moderated the relationship between work context and psychological outcomes. Work contexts characterised by a preponderance of job resources appear to facilitate both satisfaction with life and dedication.     

Validation of a Community Collective Efficacy Scale in an African Context

The aim of this study was to validate a community collective efficacy scale in an African context. An abridged version of the Community Collective Efficacy Scale was validated in a cross-sectional survey design. Participants (N = 1050) from urban (n = 451) and rural (n = 599) areas completed the CCES and other measures of self-efficacy and psychological well-being. Results indicated a Cronbach alpha reliability coefficient of 0.72 and satisfactory inter-item correlations ranging between 0.17 and 0.25. Significant correlations between the CCES and other measures of self-efficacy and psychological well-being indicated good criterion-related validity. Construct validity was supported by confirmatory and exploratory factor analysis. Exploratory factor analysis yielded one factor that relates to a sense of “we-ness”. The CCES thus has good reliability and validity in an African context.     

Investigating medical decision‐making capacity in patients with cognitive impairment using a protocol based on linguistic features

A critical question is whether cognitively impaired patients have the competence for autonomous decisions regarding participation in clinical trials. The present study aimed to investigate medical decision‐making capacity by use of a Swedish linguistic instrument for medical decision‐making (LIMD) in hypothetical clinical trials in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). Three comparable groups (age, education) participated in the study: AD (n = 20; MMSE: 24.1 ± 3.3) and MCI (n = 22; MMSE: 26.7 ± 2.4) patients and healthy controls (n = 37; MMSE: 29.1 ± 1.0). Medical decision‐making capacity was operationalized as answers to questions regarding participation in three hypothetical clinical trials. Answers were scored regarding comprehension, evaluation and intelligibility of decisions, and a total LIMD score was used as the measure of medical decision‐making ability. Groups differed significantly in LIMD with AD patients performing worst and MCI poorer than the control group. A strong association was found between all LIMD scores and diagnosis which supported the assertion that LIMD as it is designed is a one‐dimensional instrument of medical decision‐making capacity (MDMC). The results indicate that a fundamental communicative ability has an impact on the competence for autonomous decisions in cognitive impairment.
