Meaning in life and adjustment to daily stressors

People perceive their life as meaningful when they find coherence in the environment. Given that meaning of life is tied to making sense of life events, people who lack meaning would be more threatened by stressful life events than those with a strong sense of meaning in life. Four studies demonstrated links between perceptions of life’s meaningfulness and perceived levels of stress. In Study 1, participants with lower levels of meaning in life reported greater stress than those who reported higher meaning in life. In Study 2 and Study 3, participants whose meaning in life had been threatened experienced greater stress than those whose meaning in life had been left intact. In Study 4, anticipation of future stress caused participants to rate themselves higher on the quest for meaning in life. These findings suggest that perceiving life as meaningful functions as a buffer against stressors.     

Incremental theories of weight and healthy eating behavior

We examined whether a belief in weight as malleable (an incremental theory) leads to healthier eating than a belief that weight is fixed (an entity theory). Participants with incremental theories of weight consumed fewer calories from high‐calorie foods in a lab‐based taste‐test than did those with more entity theories of weight. This pattern held correlationally, with naturally occurring theories of weight (Study 1), and when we experimentally manipulated participants’ theories of weight (Study 2). A third study provided evidence that differences in self‐efficacy regarding food mediate the relationship between theories of weight and eating behavior (Study 3). One way to encourage healthy eating might be to develop interventions that encourage more incremental views of weight.     

When sex doesn’t sell to men: mortality salience,disgust and the appeal of products and advertisements featuring sexualized women

Although men typically hold favorable views of advertisements featuring female sexuality, from a Terror Management Theory perspective, this should be less the case when thoughts of human mortality are salient. Two experiments conducted in South Korea supported this hypothesis across a variety of products (e.g., perfume and vodka). Men became more negative towards advertisements featuring female sexuality, and had reduced purchase intentions for those products, after thinking about their own mortality. Study 2 found that these effects were mediated by heightened disgust. Mortality thoughts did not impact women in either study. These findings uniquely demonstrate that thoughts of death interact with female sex-appeal to influence men’s consumer choices, and that disgust mediates these processes. Implications for the role of emotion, and cultural differences, in terror management, for attitudes toward female sexuality, and for marketing strategies are discussed.     

The need for status as a hidden motive of knowledge-sharing behavior: An application of costly signaling theory

This study draws on costly signaling theory (CST) and explores the hidden motive of proactive knowledge sharing. We theorize that the need for status drives employees to generously share their tacit knowledge and special expertise to obtain social recognition and status as conferred by supervisory appraisal. We tested our hypotheses based on the moderated mediation model using a sample of 146 supervisor–subordinate dyads that were collected from South Korean organizations. The present analysis supports the proposed theoretical framework based on CST, thereby providing new insights into the need for status as an unexplored hidden motive of proactive knowledge sharing and the roles of job design factors as contextual contingencies. This study offers theoretical and practical implications related to knowledge management, employee motivation, and job design.     

The Effects of Decoys on Preference Shifts: The Role of Attractiveness and Providing Justification

The relative preference for a target product over a competitor can be increased by providing a third alternative (a “decoy”) that is clearly inferior to the target but is not necessarily inferior to the competitor. In 3 experiments, we examined the conditions in which these decoy effects occur. When participants reported their preferences immediately after being exposed to the information about them, the influence of decoys on preferences was attributable to the justification they provided for choosing the target over the competitor. (That is, a decoy had an impact if and only if the target was superior to the decoy but the competitor was not.) When participants evaluated each product individually before making their choices, however, they based their preferences on these evaluations. In this case, decoys exerted their influence through their impact on the values that participants assigned to the attributes on which the evaluations were based. This influence was evident even when the decoy was clearly inferior to both the target and competitor. Moreover, it occurred under conditions in which the target and competitor were in different product categories and also when the decoy was in a totally different product domain than the target and competitor.     

Inhibiting Irrelevant Information in Malingered Amnesia

Contributions of processing ability and knowledge to verbal memory tasks across the adult life-span

This study investigated the relationships of processing capacity and knowledge to memory measures that varied in retrieval difficulty and reliance on verbal knowledge in an adult life-span sample (N = 341). It was hypothesized that processing ability (speed and working memory) would have the strongest relationship to tasks requiring active retrieval and that knowledge (vocabulary ability) would be related to verbal fluency and cued recall, as participants relied upon verbal knowledge to retrieve category items (fluency) or develop associations (cued recall). Measurement and structural equation models were developed for the entire sample and separately for younger (aged 20-54 years, n = 168) and older (aged 55-92 years, n = 173) subgroups. In accordance with the hypotheses, processing ability was found to be most highly related to free recall, with additional significant relationships to cued recall, verbal fluency, and recognition. Knowledge was found to be significantly related only to verbal fluency and to cued recall. Moreover, knowledge was more important for older than for younger adults in mediating variance in cued recall, suggesting that older adults may use age-related increases in knowledge to partially compensate for processing declines when environmental support is available in memory tasks.     

Hypothetico-Deductivism is Still Hopeless

Since Christensen refuted the Bootstrap theory of confirmation in 1990, there have been some trials to improve the Hypothetico-Deductive theory of confirmation. After some trials, Gemes (1998) declared that his revised version completely overcame the difficulties of Hypothetico-Deductivism without generating any new difficulties. In this paper, I will assert that Gemes's revised version encounters some new difficulties, so it cannot be a true alternative to the Bootstrap theory of confirmation and to classical Hypothetico-Deductivism. Also I will assert that, in principle, such new difficulties cannot be overcome by any trials dependent only on formal logic.
