The Impact of Time‐Keeping Direction on Compensatory Consumption: The Role of Perceived Resource Deficiency

Time is a scarce resource, and time‐keeping has become a common part of our lives. This research investigates the impact of exposure to a specific direction of time‐keeping on resource deficiency perception and on compensatory consumption of calories. Results from four studies show that exposure to downward time‐keeping (e.g., 60→1 s), compared to upward time‐keeping (e.g., 1→60 s), results in a higher perceived resource deficiency, leading to a higher preference, consumption, and choice of caloric foods. The effect is attenuated for evaluation of calorie‐lean foods, or by recalling instances of resourcefulness, or when time is not a resource (as in the case of waiting). Related alternate explanations are addressed. This research is the first to identify a novel antecedent of resource deficiency (i.e., time‐keeping direction), and to elicit an unexplored aspect of temporal cognition, that exposure to direction of time‐keeping can influence compensatory consumption in an unrelated domain. These findings contribute to the literature on temporal cognition and resource deficiency and may inspire further research in these domains.     

Self-esteem,motivation and school attendance among sub-Saharan African girls: A self-determination theory perspective

Sub-Saharan samples are severely under-represented in the psychological literature. Taking an ecological approach, the current study examines key propositions derived from self-determination theory in a sample of adolescent girls in Mozambique. As a framework theory, self-determination theory consists of six sub-theories. We test the main premises of two of these theories: organismic integration theory and basic psychological need theory. In line with organismic integration theory, we assess the role of intrinsic, extrinsic, introjected and identified motivation for school attendance. We also test the possible moderating role of the ecological variable resource scarcity. The second part of the study focuses on the main premise of the basic psychological need sub-theory, which states that satisfaction of the needs for relatedness, competence and autonomy underlies intrinsic motivation, goal-directed behaviour (school attendance) and well-being (self-esteem). The study also assesses the moderation of resource scarcity in these relationships. Results provide support for both sub-theories of self-determination theory. Resource scarcity is not found to moderate the relationships between motivation and attendance or between need satisfaction and well-being, motivation and attendance. Implications for the universality claim of self-determination theory, as well as for the field of international development aid, are discussed.     

Perceptions of injustice in intercultural relations

Perceptions of injustice are likely to occur in intercultural relations because cultures often define justice and its implementation differently. This article reviews factors and processes that are unique to intercultural relations and that may give rise to feelings of injustice during intercultural interactions. Antecedents that can trigger a sense of injustice with regard to distributive, procedural, and retributive justice are reviewed. The consequences of perceived injustice are also analyzed. The implications of our analysis for research and practice are discussed.     

稀缺对个体心理和行为的影响：基于一个更加整合视角下的阐释

稀缺是由资源的真实缺乏或感知缺乏所引起的个体欲望和需求得不到满足的一种状态。稀缺作为一种普遍存在的现象对个体的情感、认知、以及行为方式产生了重要的影响, 但是不同类型的稀缺(以食物、产品、资金为代表的有形资源稀缺vs.以时间为代表的无形资源稀缺)对个体心理和行为的影响是否存在共性与差异?梳理文献发现, 有形资源稀缺会使个体产生珍惜性行为、补偿性行为和趋近性行为, 而无形资源稀缺只会使个体产生珍惜性和补偿性行为。未来研究应关注稀缺影响个体行为的边界条件, 以及时间稀缺对个体心理和行为的影响。     

Cognitive performance is improved while walking: Differences in cognitive–sensorimotor couplings between children and young adults

We investigated how 9-year-olds and young adults performed a working memory task under different difficulty conditions while walking on a treadmill. Stride-length and stride-time variability tended to decrease with cognitive load in young adults, whereas children showed an increase in walking variability when cognitive load was very high. Participants in both age groups improved their cognitive performance when walking at their preferred speed as opposed to sitting or walking at a fixed, non-preferred speed. We conclude that the interaction of walking and cognitive performance is influenced by sharing resources between two tasks, and that performance improvements in cognition may be caused by an exercise-induced activation of resources.     

Memory and comprehension for health information among older adults: Distinguishing the effects of domain-general and domain-specific knowledge

While there is evidence that knowledge influences understanding of health information, less is known about the processing mechanisms underlying this effect and its impact on memory. We used the moving window paradigm to examine how older adults varying in domain-general crystallised ability (verbal ability) and health knowledge allocate attention to understand health and domain-general texts. Participants (n = 107, age: 60–88 years) read and recalled single sentences about hypertension and about non-health topics. Mixed-effects modelling of word-by-word reading times suggested that domain-general crystallised ability increased conceptual integration regardless of text domain, while health knowledge selectively increased resource allocation to conceptual integration at clause boundaries in health texts. These patterns of attentional allocation were related to subsequent recall performance. Although older adults with lower levels of crystallised ability were less likely to engage in integrative processing, when they did, this strategy had a compensatory effect in improving recall. These findings suggest that semantic integration during reading is an important comprehension process that supports the construction of the memory representation and is engendered by knowledge. Implications of the findings for theories of text processing and memory as well as for designing patient education materials are discussed.     

Personhood: Elusive But Not Illusory

Bioethics as a field has been fortunate that its values and concerns have mirrored the values and concerns of society. In light of the September 11th attacks, it is possible that we are witnessing the beginning of a transition in American culture, one fraught with implications for bioethics. The emphasis on autonomy and individual rights may come to be tempered by greater concern over the collective good. Increased emphasis on solidarity over autonomy could greatly alter public response to research abuses aimed at defense from bioterrorism, to privacy of genetic information, and to control of private medical resources to protect the public health.     

The effect of evolving resource synergy beliefs on the intentions–behavior discrepancy in ethical consumption

Consumers are less likely to buy ethical products than their stated intentions in marketplace polls, due at least in part to the distinct temporal frames guiding their poll responses versus actual purchase decisions. We propose that as consumers' beliefs about the synergy between the resources a firm devotes to their ethical and functional attributes evolve, as part of the broader ethical marketing/corporate social responsibility movement, from negative to positive, this discrepancy between intentions and behavior is likely to disappear. Two studies provide support for this basic contention, implicating the importance consumers ascribe to a brand's ethical attribute as the driver of the temporal frame- and resource synergy beliefs-based differences in their preference for that brand.     

Creative production by angry people peaks early on, decreases over time, and is relatively unstructured

Anecdotes and introspective reports from eminent scientists and artists aside, a systematic test of the putative creativity-enhancing effect of anger is missing. This article fills this void with three experiments examining creativity as a function of anger (vs. sad or a mood-neutral control state). Combining insights from the literatures on creativity and on mood and information processing the authors predicted that anger (vs. sadness and a mood-neutral control state) triggers a less systematic and structured approach to the creativity task, and leads to initially higher levels of creativity (as manifested in original ideation and creative insights). Following work on resource depletion, the authors further predicted that anger more than sadness depletes resources and that, therefore, creative performance should decline over time more for angry than for sad people. Results supported predictions. Implications for creativity, information processing, and resource depletion are discussed.     

Welfare Rights and Conflicts of Rights

The fact that welfare rights – rights to food, shelter and medical care – will conflict with one another is often taken to be good reason to exclude welfare rights from the catalogue of genuine rights. Rather than respond to this objection by pointing out that all rights conflict, welfare rights proponents need to take the conflicts objection seriously. The existence of potentially conflicting and more weighty normative considerations counts against a claim’s status as a genuine right. To think otherwise would be to threaten the peremptory force – and hence the analytical integrity – of rights. The conflicts objection is made more pressing once we have conceded that welfare rights give people entitlements to what are potentially scarce goods. I argue that welfare rights can survive the conflicts objection if, and only if, we take scarcity into account in the framing of a given welfare right.
