Positive Adaptation in a Community of Postgraduate Students: Applying the Mmogo-method™

This study explored the experiences of postgraduate psychology students exposed to continuous challenges and described their positive adaptation as a community. Three males and 14 females (age range: 23–30 years; 1 black, 3 coloured, 2 Indian and 11 white) took part in the study. Data were obtained through the Mmogo-method?, group discussions on the visual presentations, written texts and an in-depth interview. The findings indicated that threats from outside as well as from within a community have implications for the community's positive adaptation. Positive adaptation develops through cyclical processes. It depends on the availability of tangible (financial, teaching) and personal (humour) resources. Among the outcomes of positive adaptation are that people who share challenging experiences report a sense of belonging and hope and also respect for diversity. Positive adaptation helps a community strengthen and protect its members.     

A randomized clinical trial of Behavioral Activation (BA) therapy for improving psychological and physical health in dementia caregivers: Results of the Pleasant Events Program (PEP)

Dementia caregiving is associated with elevations in depressive symptoms and increased risk for cardiovascular diseases (CVD). This study evaluated the efficacy of the Pleasant Events Program (PEP), a 6-week Behavioral Activation intervention designed to reduce CVD risk and depressive symptoms in caregivers. One hundred dementia family caregivers were randomized to either the 6-week PEP intervention (N = 49) or a time-equivalent Information-Support (IS) control condition (N = 51). Assessments were completed pre- and post-intervention and at 1-year follow-up. Biological assessments included CVD risk markers Interleukin-6 (IL-6) and D-dimer. Psychosocial outcomes included depressive symptoms, positive affect, and negative affect. Participants receiving the PEP intervention had significantly greater reductions in IL-6 (p = .040), depressive symptoms (p = .039), and negative affect (p = .021) from pre- to post-treatment. For IL-6, clinically significant improvement was observed in 20.0% of PEP participants and 6.5% of IS participants. For depressive symptoms, clinically significant improvement was found for 32.7% of PEP vs 11.8% of IS participants. Group differences in change from baseline to 1-year follow-up were non-significant for all outcomes. The PEP program decreased depression and improved a measure of physiological health in older dementia caregivers. Future research should examine the efficacy of PEP for improving other CVD biomarkers and seek to sustain the intervention's effects.     

The Effectiveness of Sentence Cues in Measuring the Big Three Motives

Despite the popularity of free response measures in the motivation literature, research geared toward the development of a standard battery of cues for measuring the Big Three motives (achievement, affiliation, power) has been lacking. The current research examined the effectiveness of sentence cues in eliciting motive imagery in two studies (students, entrepreneurs) comprising 242 men and women. Results indicated that sentence cues were effective in eliciting achievement and affiliation imagery, but not power imagery. In addition, an examination of the subcategories underlying each motive scoring system indicated that there were several infrequently scored subcategories in the achievement and power motive scoring systems that could be considered for removal.     

The MMPI-2 With College Students

MMPI-2 responses of 515 male and 797 female college students from four universities were examined. College students were compared with the new MMPI-2 normative sample on the clinical and validity scales. The reliability of MMPI-2 scores of college students were compared with reliabilities of the MMPI-2 normative sample. The results indicated that college students respond to the MMPI-2 in a highly similar manner to the MMPI-2 normative sample. Mean score differences on the validity and clinical scales were within 1 to 3 T-score points on most scales, and the frequency distributions of the college students were highly similar to those of the MMPI-2 normative samples, Slight differences obtained on the Pt, Sc, and Ma scales may reflect the younger age of the college groups compared to the MMPI-2 normative groups. The MMPI-2 norms were shown to be appropriate for use with college subjects. Test-retest correlation coefficients obtained from college students who were administered the MMPI-2 on two occasions showed reliabilities comparable to those found for the MMPI-2 normative sample.     

Consequences of anticipatory processing on cognitive symptoms of social anxiety

Anticipatory processing is an anxious style of repetitive negative thought associated with social anxiety (SA) that was proposed by Clark and Wells. Considerable research has examined factors of Clark and Wells' cognitive model of SA (e.g. attention, interpretation), but few studies have examined anticipatory processing, which is hypothesized to interact with other components in the model. In the current study, individuals high in social anxiety symptoms (HSA; N = 56) and control participants [Normal Control (NC); N = 52] engaged in an anticipation or distraction task prior to a threatened social interaction. HSAs who anticipated had higher self-focused attention than NCs who anticipated and HSAs in the distraction condition, suggesting an important relationship between anticipation and self-focus that is specific to HSAs. Those who anticipated endorsed more negative interpretations than those who engaged in distraction, regardless of SA status. However, this relationship was mediated by self-focus. Implications in the context of Clark and Wells' model and future directions are discussed.     

Personality and the response to predation risk: effects of information quantity and quality

Within aquatic ecosystems, chemosensory cues provide valuable public information regarding the form and degree of risk, allowing prey to make informed behavioural decisions. Such cues, however, may vary in both relative concentration detected (i.e. ‘quantity’) and reliability of the information available (i.e. ‘quality’), leading to varying response patterns. Moreover, prey species are also known to exhibit consistent behavioural tactics towards managing risk (i.e. personality), possibly shaping their use of public information. Here, we present two experiments examining the potential interacting effects of personality and the quantity (Experiment 1) or quality (Experiment 2) of public information on the short-term predator avoidance responses of wild-caught Trinidadian guppies under semi-natural conditions. Our first experiment demonstrated that personality shaped responses to a high concentration of alarm cues (high risk), with shyer guppies exhibiting stronger antipredator responses than bolder guppies. When exposed to either low risk or stream water controls, personality had no effect on the intensity of response. Our second experiment demonstrated that personality again shaped the response to high concentrations of alarm cues (a known risk) but not to a novel chemosensory cue (tilapia odour). When exposed to the unknown novel cue, guppies exhibited a relatively high intensity antipredator response, regardless of personality. Combined, our results suggest that individual risk-taking tactics shape the use of public information in a context-dependent fashion.     

Convincing Yourself to Care About Others: An Intervention for Enhancing Benevolence Values

To study value change, this research presents an intervention with multiple exercises designed to instigate change through both effortful and automatic routes. Aiming to increase the importance attributed to benevolence values, which reflect the motivation to help and care for others, the intervention combines three mechanisms for value change (self‐persuasion, consistency‐maintenance, and priming). In three experiments, 142 undergraduates (67% male, ages 19–26) participated in an intervention emphasizing the importance of either helping others (benevolence condition) or recognizing flexibility in personality (control condition). We measured the importance of benevolence values before and after the task. In Experiment 1, the intervention increased U.S. participants' benevolence values. In Experiment 2, we replicated these effects in a different culture (Israel) and also showed that by enhancing benevolence values, the intervention increased participants' willingness to volunteer to help others. Experiment 3 showed that the increases in the importance of benevolence values lasted at least 4 weeks. Our results provide evidence that value change does not require fictitious feedback or information about social norms, but can occur through a 30‐min intervention that evokes both effortful and automatic processes.     

Towards a Functional Approach to Modular Ontologies Using Institutions

We propose a functional view of ontologies that emphasises their role in determining answers to queries, irrespective of the formalism in which they are written. A notion of framework is introduced that captures the situation of a global language into which both an ontology language and a query language can be translated, in an abstract way. We then generalise existing notions of robustness from the literature, and relate these to interpolation properties that support modularisation of ontologies.
