Olfactory acuity and cognitive function converge in older adulthood: support for the common cause hypothesis

Visual and auditory thresholds and cognitive variables have shown converging losses in old age, which might exist because standard cognitive tests rely on these modalities for assessment. The present study investigated the common cause hypothesis in another sensory modality. Structural equation modeling tested the fit of a model representing the common cause hypothesis for olfactory acuity and cognitive function data from 98 nondemented older adults and 103 younger adults. The model fit better the data from the older adults, consistent with the common cause hypothesis. In addition, unique influences of age beyond those shared between cognitive and sensory variables were also demonstrated. The results suggest that olfactory functioning may be a valid indicator of the integrity of the aging brain in older adults.     

Attachment theory and group processes: the association between attachment style and group-related representations,goals, memories,and functioning

Four studies examined attachment-style differences in group-related cognitions and behaviors. In Studies 1-2, participants completed scales on group-related cognitions and emotions. In Studies 3-4, participants were divided into small groups, and their performance in group tasks as well as the cohesion of their group were assessed. Both attachment anxiety and avoidance in close relationships were associated with negative group-related cognitions and emotions. Anxiety was also related to the pursuit of closeness goals and impaired instrumental performance in group tasks. Avoidance was related to the pursuit of distance goals and deficits in socioemotional and instrumental performance. Group cohesion significantly moderated the effects of attachment anxiety. The discussion emphasizes the relevance of attachment theory within group contexts.     

Screening for Posttraumatic Stress Disorder: an evaluation of two self-report scales among crime victims

The validity of the Impact of Events Scale (IES) and the Posttraumatic Stress Disorder (PTSD) Symptom Scale, Self-Report version (PSS-SR) was examined among crime victims. Both instruments performed well as screeners for PTSD. For the IES, sensitivity ranged between .93 and 1.00; for the PSS-SR, sensitivity ranged between .80 and .90. Specificity for the IES ranged between .78 and .84 and for the PSS-SR ranged between .84 and .88. Some individual items from the 2 scales performed just as well as the total scales. The authors conclude that either of these short self-report instruments or their individual items are suitable as screeners for PTSD, specifically in settings where mental health professionals are unavailable. Cross-validation of these results is necessary because of the small sample size in this study.     

Mental pain: a multidimensional operationalization and definition

An operationalization of mental pain is presented in three studies. The first study describes the operationalization of mental pain and the factor structure of the items produced by a content analysis of self-reports yielding a scale with nine factors: the experience of irreversibility, loss of control, narcissistic wounds, emotional flooding, freezing, estrangement, confusion, social distancing, and emptiness. Study 2 tested the relationship between mental pain and depression and anxiety in a normal population. Study 3 focused on the relationship between mental pain and coping. Mental pain is conceptualized as a perception of negative changes in the self and its functions that are accompanied by negative feelings. It is suggested that it can be meaningfully applied to the study of different mental states, life conditions, and transitions in life.     

Social class and wellbeing among staff and students in higher education settings: Mapping the problem and exploring underlying mechanisms

Within Higher Education (HE), staff and students from lower social class backgrounds often experience poorer wellbeing than their higher social class counterparts. Previous research conducted outside educational contexts has linked social class differences in wellbeing with differences in the extent to which low and high social class individuals feel respected (i.e., status), in control (i.e., autonomy), and connected with others (i.e., inclusion). However, to our knowledge, there has been no research that has investigated these psychosocial needs within HE settings. Furthermore, inclusion, status and autonomy are correlated, yet little is known about how these psychosocial needs contribute to wellbeing simultaneously, and independently, of one another. To fill these gaps, we report the results of two studies; firstly with HE students (Study 1; N = 305), and secondly with HE staff (Study 2; N = 261). Consistently across studies, reports of poor wellbeing were relatively common and more than twice as prevalent amongst lower social class staff and students compared to higher social class staff and students. Inclusion, status and autonomy each made a unique contribution and accounted for the relationship between social class and wellbeing (fully amongst students, and partially amongst staff members). These relationships held across various operationalizations of social class and when examining a range of facets of wellbeing. Social class along with inclusion, status and autonomy explained a substantial 40% of the variance in wellbeing. The present research contributes to the literature exploring how social class intersects with psychosocial needs to impact the wellbeing of staff and students within HE.     

<Emphasis Type="Bold">Ultrahigh temporal resolution of visual presentation using gaming monitors and G-Sync</Emphasis>

Vision unfolds as an intricate pattern of information processing over time. Studying vision and visual cognition therefore requires precise manipulations of the timing of visual stimulus presentation. Although standard computer display technologies offer great accuracy and precision of visual presentation, their temporal resolution is limited. This limitation stems from the fact that the presentation of rendered stimuli has to wait until the next refresh of the computer screen. We present a novel method for presenting visual stimuli with ultrahigh temporal resolution (<1 ms) on newly available gaming monitors. The method capitalizes on the G-Sync technology, which allows for presenting stimuli as soon as they have been rendered by the computer’s graphics card, without having to wait for the next screen refresh. We provide software implementations in the three programming languages C++, Python (using PsychoPy2), and Matlab (using Psychtoolbox3). For all implementations, we confirmed the ultrahigh temporal resolution of visual presentation with external measurements by using a photodiode. Moreover, a psychophysical experiment revealed that the ultrahigh temporal resolution impacts on human visual performance. Specifically, observers’ object recognition performance improved over fine-grained increases of object presentation duration in a theoretically predicted way. Taken together, the present study shows that the G-Sync-based presentation method enables researchers to investigate visual processes whose data patterns were concealed by the low temporal resolution of previous technologies. Therefore, this new presentation method may be a valuable tool for experimental psychologists and neuroscientists studying vision and its temporal characteristics.     

Is masked priming modulated by memory load? A test of the automaticity of masked identity priming in lexical decision

One of the key assumptions of the masked priming lexical decision task (LDT) is that primes are processed without requiring attentional resources. Here, we tested this assumption by presenting a dual-task manipulation to increase memory load and measure the change in masked identity priming on the targets in the LDT. If masked priming does not require attentional resources, increased memory load should have no influence on the magnitude of the observed identity priming effects. We conducted two LDT experiments, using a within-subjects design, to investigate the effect of memory load (via a concurrent matching task Experiment 1 and a concurrent search task in Experiment 2) on masked identity priming. Results showed that the magnitude of masked identity priming on word targets was remarkably similar under high and low memory load. Thus, these experiments provide empirical evidence for the automaticity assumption of masked identity priming in the LDT.     

The Postsecular Turn in Education: Lessons from the Mindfulness Movement and the Revival of Confucian Academies

It is part of a global trend today that new relationships are being forged between religion and society, between spirituality and materiality, giving rise to announcements that we live in a ‘postsecular’ or ‘desecularized’ world. Taking up two educational movements, the mindfulness movement in the West and the revival of Confucian education in China, this paper examines what and how postsecular orientations and sensibilities penetrate educational discourses and practices in different cultural contexts. We compare the two movements to reveal a new quality of hybrid modernization in that they react, in different ways, to certain pathologies that are identified as consequences of secular modernity. Burnout syndrome, the sense of a spiritual void, but also the loss of a spiritual and cultural identity are being perceived as correlating to a one-sided push towards a modernity that emphasizes secular rationalization over mindfulness and Westernization over cultural particularity. The two case studies mark a critical insight on the present condition and limits of secularism and highlights the ongoing negotiations of values and modes of self-cultivation in schools. In an increasingly pluralistic world, the entanglement of the secular, spiritual, religious and wisdom traditions provides the opportunity to rethink education as a creative realm and an impossible possibility to re-engage the minds and lives of those in the hybrid pedagogical time.     

Reassuring sex: Can sexual desire and intimacy reduce relationship‐specific attachment insecurities?

Past research has shown that attachment orientations shape sexual processes within relationships. Yet, little has been done to explore the opposite direction. In the present research, we examined whether sexual desire and emotional intimacy reduce attachment insecurities over time in emerging relationships. In an 8‐month longitudinal study, we followed 62 newly dating couples across three measurement waves. At Time 1, romantic partners discussed sexual aspects of their relationship and judges coded their displays of sexual desire and intimacy. Participants also completed measures of relationship‐specific attachment anxiety and avoidance in each wave. The results indicated that men's displays of desire predicted a decline in their own and their partner's relationship‐specific insecurities. Conversely, women's displays of desire inhibited the decline in their partner's relationship‐specific insecurities, whereas women's displays of intimacy predicted a decline in their partner's relationship‐specific insecurities. These findings suggest that different sex‐related processes underlie attachment formation in men and women.
