Affective primes may impact ensuing behavior through condition and person effects. However, previous research has not experimentally disentangled these two sources of influence in affective priming paradigms. In the current research, we simultaneously examine the influence of condition factors, in terms of prime valence, and person factors, in terms of affect reactivity and personality. In both studies, undergraduate participants (total N = 174) were primed with either positive or negative affective stimuli (words, Study 1; pictures, Study 2) prior to judging the likability of a neutral target (Arabic characters, Study 1; inkblots, Study 2). Although we did observe between‐condition differences for positive and negative primes, person‐level effects were more consistent predictors of target ratings. Affect reactivity (affect Time 2, controlling Time 1) to the primes predicted evaluative judgments, even in the absence of condition effects. In addition, the personality traits of Neuroticism (Study 1) and behavioral inhibition system sensitivity (Study 2) predicted evaluative judgments of neutral targets following negative affective primes. With effects for condition, affect reactivity, and personality, our results suggest that affective primes influence ensuing behaviors through both informational and affective means. Research using affective priming methodologies should take into account both condition and person‐level effects. 相似文献

AbstractSubstantial research has found relations between religiosity and martial satisfaction. More longitudinal studies are needed to understand the inner-workings of this relationship. Over a four-year period, dyadic data from 331 married couples was used to test the longitudinal mediating effects of spousal forgiveness and partners’ perceptions of spousal forgiveness between religiosity and marital satisfaction. Husbands’ religiosity was associated with increases in wives’ marital satisfaction but the measures of forgiveness were not significant mediators in this relationship. Wives’ religiosity was predictive of lower levels of wives’ perceptions of spousal forgiveness, which led to decreases in both wives’ and husbands’ marital satisfaction. 相似文献

Although increasing exercise and fitness has often been associated with positive health outcomes, infrequent exercise participation has remained a problem. Since two distinct motivational and volitional phases to goal pursuit have been proposed, a combined motivational (decision balance sheet, DBS) and volitional (implementation intentions) intervention was predicted to be more effective in increasing exercise behaviour than a control or either strategy alone. A total of 86 students were randomly assigned to one of the four conditions, and were all asked to try to exercise two more times a week than they currently did, over a four week period. Their fitness levels were measured through fitness tests conducted pre- and post-intervention. A priori orthogonal contrasts indicated that the experimental strategies produced a greater increase in exercise frequency and total time spent exercising per week and accordingly showed greater fitness improvements than the control group. Moreover, the volitional groups taken together produced greater increase in time spent exercising and a marginally greater improvement in frequency than the DBS alone. The combined intervention led to improvements in fitness and marginal increases in frequency over the implementation intention alone group. It is proposed that for the combined group the DBS may have aided recall of the implementation intention or increased commitment to it, as remembering and then acting on the plan, in the stated place and time, mediated the implementation intention–behaviour relationship. The combined intervention produced the greatest fitness improvements, indicating that this strategy can lead to important health benefits. 相似文献

In a series of experiments we tested 4- and 8-month-olds’ ability to represent the spatial layout of an object across changes in its orientation with respect to egocentric spatial coordinates. A fixed-trial familiarization procedure based on visual habituation behaviour shows that both age groups are able to discriminate between different object-centred spatial configurations. Furthermore, both age groups demonstrate the ability to make discriminations of object-centred spatial coordinates that require simultaneous reference to at least two spatial axes of the object. We discuss these findings in relation to theories of the early development of object recognition and spatial reference skills. 相似文献

If derogation of out-groups serves the function of bolstering self-esteem, it is possible that this effect can be counteracted by means of existential relief. Two variables were presented in a 2 × 2 factorial to a population of primarily college students: a mortality salience (MS) variable and an afterlife variable, in which participants read “scientific” accounts that either supported or denied the existence of a literal afterlife. Homonegativity was utilised as a dependent measure of out-group derogation. In the predicted manner, mortality salience and afterlife variables interacted to predict significantly different levels of homonegativity. When participants were subconsciously primed with MS, their psychological need to derogate dissimilar others was significantly lowered if they were assured of an afterlife. These results demonstrate that the effects of MS can be attenuated by presenting existential relief through assurance of literal afterlife. 相似文献

Although social scientists have convincingly demonstrated relationships between religious beliefs/practices and mental health, almost none of the empirical findings or related theory apply specifically to Jews. To address this limitation, we investigated the role of Jewish religiousness in anxiety, depression, and happiness, in a large Jewish community sample (n = 565). Several facets of global Jewish religiousness were examined, as well as a theoretically based Jewish religious variable, trust in God. A self-report measure of trust in God was created, and factor analyses yielded two reliable and valid subscales: trust in God and mistrust in God. Contrary to our hypotheses, global Jewish religiousness was on the whole unrelated to mental-health functioning. As expected, higher levels of trust in God were associated with less anxiety and depression, and greater personal happiness, whereas inverse associations emerged for the unanticipated but robust mistrust subscale. 相似文献

ABSTRACT Episodic memory is the first and most severely affected cognitive domain in Alzheimer's disease (AD), and it is also the key early marker in prodromal stages including amnestic mild cognitive impairment (MCI). The relative ability of memory tests to discriminate between MCI and normal aging has not been well characterized. We compared the classification value of widely used verbal memory tests in distinguishing healthy older adults (n = 51) from those with MCI (n = 38). Univariate logistic regression indicated that the total learning score from the California Verbal Learning Test-II (CVLT-II) ranked highest in terms of distinguishing MCI from normal aging (sensitivity = 90.2; specificity = 84.2). Inclusion of the delayed recall condition of a story memory task (i.e., WMS-III Logical Memory, Story A) enhanced the overall accuracy of classification (sensitivity = 92.2; specificity = 94.7). Combining Logical Memory recognition and CVLT-II long delay best predicted progression from MCI to AD over a 4-year period (accurate classification = 87.5%). Learning across multiple trials may provide the most sensitive index for initial diagnosis of MCI, but inclusion of additional variables may enhance overall accuracy and may represent the optimal strategy for identifying individuals most likely to progress to dementia. 相似文献

ABSTRACT Previous studies have indicated that aging is associated with declines in recollection whereas familiarity-based recognition is left largely unaffected. The brain changes underlying these recollection declines are yet not well understood. In the current study we examined the role of white matter integrity as measured by white matter hyperintensities (WMH) on age-related changes in recollection and familiarity. Recognition was measured using a remember/know procedure (Experiment 1) and a source-memory process-dissociation procedure (Experiment 2). Robust age related declines in recollection were observed, but there was no evidence that white matter damage was related to the observed memory declines. Although future studies with larger samples will be necessary to fully characterize the role of WMH in normal age-related declines in different types of memory, the results suggest that declines in recollection are not strongly related to the brain changes indexed by WMHs. 相似文献
