Object identification: The mental representation of physical and conceptual attributes

In two experiments, subjects indicated whether two pictures of familiar objects were equivalent. The picture pairs were identical, showed the same object in various perspectives and states, or showed different objects with varying degrees of conceptual relatedness. In Experiment 1, the equivalence criterion for judging the picture pairs was varied between subjects (identity of pictures; conceptual equivalence of objects at subordinate, basic, or superordinate level). The reaction times of the four subject groups suggest that a pictorial stimulus is not always mentally represented in the same way, and that the instructions given determine which attributes of the stimulus are represented. In Experiment 2, the visual similarity of the picture pairs was varied. The results indicate, at least with a basic-level equivalence instruction, that not only perceptual, but also non-perceptual, functional attributes are represented—namely, those that, according to Rosch et al. (1976), are common to the members of a superordinate category.     

Social integration and social support in a life crisis: Effects of macrosocial change in east Germany

The breakdown of the former communist system in East Germany was a major critical life event for those who left that country as well as for those who stayed behind. When the borders were opened, a longitudinal study was launched to examine the psychological readaptation process. Some indicators of social changes of migrants compared to nonmigrants were available. At three points in time over 2 years, both groups reported on their social bonding and social support. Migrants readjusted well by making new friends. In particular, young men were socially active, and more same-sex than opposite-sex friendships were established. The group of young migrants reported having received the most support, in particular when they had a partner. Anticipated support, in contrast, was highest for young single women who did not migrate. Results contribute to the understanding of social dynamics that occur after a stressful relocation.     

Self-efficacy and planning strategies can improve physical activity levels in women with a recent history of gestational diabetes mellitus

Introduction: Regular physical activity can reduce the risk of developing diabetes in high risk populations including in women with gestational diabetes mellitus (GDM). This study applied the Health Action Process Approach (HAPA) to determine the motivational and volitional factors important in increasing physical activity among women with previous GDM.

Methods: Women with GDM receiving obstetric care at a teaching hospital in Sri Lanka were invited to participate in a survey 6–36 months post-delivery. At baseline and 8 weeks later, 152 women completed postal and telephone surveys that collected socio-cognitive and physical activity data. The study hypotheses were tested using structural equation modelling.

Results: The modified model fit the data well (CFI = .95, TLI = .94, RMSEA = .057) and explained 11% of the variance in behaviour. Action self-efficacy was the only important predictor of intention to be physically active. Intention as well as maintenance self-efficacy predicted planning, which, in turn, predicted physical activity. Planning mediated the effect of intention and self-efficacy (maintenance and recovery) on physical activity.

Conclusion: This study has identified predictors of physical activity among women with previous GDM that can inform intervention studies. Interventions targeting this population need to include planning strategies and enhance self-efficacy.     

Social-Cognitive Factors in Changing Health-Related Behaviors

Changing health-related behaviors requires two separate processes that involve motivation and volition, respectively. First, an intention to change is developed, in part on the basis of self-beliefs. Second, the change must be planned, initiated, and maintained, and relapses must be managed; self-regulation plays a critical role in these processes. Social-cognition models of health behavior change address these two processes. One such model, the health action process approach, is explicitly based on the assumption that two distinct phases need to be studied longitudinally, one phase that leads to a behavioral intention and another that leads to the actual behavior. Particular social-cognitive variables may play different roles in the two stages; perceived self-efficacy is the only predictor that seems to be equally important in the two phases.     

What Can Causal Claims Mean?

How can Hume account for the meaning of causal claims? The causal realist, I argue, is, on Hume's view, saying something nonsensical. I argue that both realist and agnostic interpretations of Hume are inconsistent with his view of language and intentionality. But what then accounts for this illusion of meaning? And even when we use causal terms in accordance with Hume’s definitions, we seem merely to be making disguised self-reports. I argue that Hume’s view is not as implausible as it sounds by exploring his conception of language.     

Beyond sentence boundaries: Grammatical gender information in short-term recall of texts

In the context of text recall it is often stated that surface representations are quickly forgotten. Jarvella (1971) and Sachs (1967) argued that what is retained beyond sentence boundaries is meaning information, whereas lexical and syntactic information is only available for the most recent constituent. We based a text recall experiment on Jarvella’s paradigm, in order to demonstrate that both meaning and grammatical gender information contribute to the recall of short text passages. Although it is known that grammatical gender information is used in anaphor resolution, even if noun and pronoun do not belong to adjacent sentences, there is no direct evidence for a gender contribution to text memory so far. The present experiment demonstrates that grammatical gender information, even when of no semantic importance, is retained beyond sentence boundaries and can contribute to the memory representation of subsequent text.

Embodied learning: Teaching sexuality and religion to a changing student body

Sexuality, more so than other subject areas, magnifies the embodied nature of teaching and learning as well as conspicuously silences open dialogue given its taboo status in many religious and theological contexts. Yet, student learning about sexuality that incorporates knowledge of and about religion, in particular, may greatly improve the public discourse about sexuality through our students as responsible citizens and as leaders in their chosen professions. To bridge this gap, through a year‐long collaboration, a group of professors and instructors with expertise and experience teaching sexuality and religion in a variety of disciplines and diverse institutional and religious contexts developed, tested, and refined classroom teaching strategies to shift from a content‐based “subject matter” to an embodied learning experience, resulting in perspective transformation as a primary student‐learning outcome. Findings in the form of “guiding questions,” encourage instructors to attend to contextual, experiential, and performative aspects of the classroom environment.     

Less Happiness in Cities,but Why and so What? One More Reason to Stop Overpopulation

Average happiness in big cities with more than 250,000 inhabitants is, in the USA, lower than average happiness in towns and in the country. Adam Kozaryn offers several explanations. One explanation is that core characteristics of cities, such as size, density and heterogeneity lead to a deterioration of social relations. This explanation is insufficient because average happiness in cities can also be relatively high, as is the case in poor nations, compared to happiness in towns and in the country. Important factors like relative safety and the availability of services have to be considered additionally. A second explanation is that capitalism plays a more dominant role in cities, with similar negative effects. This explanation is also insufficient because the negative effects of capitalism are not limited to cities. A more plausible explanation is that average happiness in American cities is relatively low, because of the interaction of their core characteristics and capitalism. More people should live in smaller places, but this is impossible. There are too many people and big cities are needed to minimize their ecological footprint. Overpopulation is the root of the problem. A discussion about the maximum size of the population is needed. There is no reason to fear for a negative impact on individual freedom, but people can pay attention to this discussion if they make up their mind about having children.
