Objects with curved contours are generally preferred to sharp‐angled ones. In this study, we aim to determine whether different presentation times influence this preference. We used images of real objects (experiment 1) and meaningless novel patterns (experiment 2). Participants had to select one of two images from a contour pair, curved and sharp‐angled versions of the same object/pattern. With real objects, the preference for curved versions was greatest when presented for 84 ms, and it faded when participants were given unlimited viewing time. Curved meaningless patterns were preferred when presented for 84 and 150 ms. However, in contrast to real objects, preference for meaningless patterns increased significantly in the unlimited viewing time condition. Participants discriminated poorly between the two versions (curved and sharp‐angled) of the meaningless patterns in the 84‐ and 150‐ms presentations (experiment 3). Therefore, in short times with meaningless patterns, participants selected mostly the curved version without being aware of the difference. In conclusion, presentation time, type of stimulus, and their interaction influence preference for curvature. 相似文献
In the present research, we examined whether individual differences in basic moral concerns might be related to a greater endorsement of conspiracy theories. Building on the notion that conspiracy theories often deal with super‐individual relevant events in which a group perspective is central, we proposed that individual differences in moral concerns pertaining to group‐ and community‐concerns (i.e., binding moral foundations) rather than to individual well‐being (i.e., individualising moral foundations) would be positively associated with conspiracy beliefs. We further hypothesised that such relations would be totally mediated by beliefs in a dangerous world and by embracing moral absolutism. We found support for these predictions in two community samples (Ns: 319; 514). Theoretical implications were discussed. 相似文献
The aims of this study were to analyze whether positive and negative affect, social support, and loneliness are factors longitudinally related to suicide ideation in the general population in different age groups. A total of 2,392 individuals from a nationally representative sample of the Spanish general population were evaluated in 2011–2012 and in 2014–2015. After including relevant control variables in the analyses, lower positive affect was prospectively related to ideation in 18‐ to 59‐year‐old individuals, whereas feelings of loneliness were related to ideation in 60‐year‐and‐older individuals. Social support was not associated with suicide ideation in any age group. These results are in line with the need for age‐tailored suicide prevention programs. The present findings might also suggest that health care professionals should consider feelings of loneliness rather than social support to assess the presence of suicide ideation in older people. 相似文献
This study is grounded in Allport's intergroup contact theory and Herek's sexual prejudice theory. We aimed at (a) investigating the mediational role of sexism and homonegativity on the relation between gender, age, and contact with gay and lesbian people with gender stereotypes about gay men and lesbians; and (b) replicating and corroborating the direct associations found in previous research among these variables. The present research used secondary data from a survey conducted by the Italian National Institute of Statistics and comprehending a representative sample of 5,863 Italian adults. The results from path analysis indicated that both homonegativity and sexism partially mediated the effect of gender and age on gender stereotypes, whereas they totally mediated the effect of contact with gay and lesbian persons. Findings suggest that reducing sexist and homonegative attitudes and increasing contact with gay and lesbian people may reduce stereotypical beliefs about homosexual people. 相似文献
This study explored the mediating role of common dyadic coping (common DC) on the longitudinal associations between attachment‐related anxiety and avoidance and parental adjustment to the first year postpartum. A total of 92 Portuguese couples completed self‐report questionnaires of romantic attachment, common DC, parenting stress, and parental confidence. Results showed that more avoidant parents (at mid‐pregnancy) engaged less in common DC (at 6 weeks postpartum), which consequently increased their partner's parenting stress (only in mothers) and decreased their partner's parental confidence (in both parents) at 6–9 months postpartum. Anxious attachment did not predict parents' adjustment directly or indirectly. Interventions aimed at preventing adjustment difficulties to early parenthood in more avoidant parents should focus on enhancing their common DC strategies soon after childbirth. 相似文献
Cognitive training can allow patients with Alzheimer’s disease (AD) to reinforce individual cognitive abilities. In the present case study, we investigated the generalizability of trained cognitive skills to novel tasks, and their stability over time.
One AD patient underwent a structured cognitive training using the GEO (Geographical Exercise for cognitive Optimization) task, whereas eight AD patients underwent a control cognitive intervention. Participants’ performances on the GEO task, on a similar untrained cognitive task, and on a different untrained cognitive task were recorded before and after the intervention, and at the follow-up. On both the trained and the similar untrained tasks patients’ and controls’ performance significantly differed from one another. Our preliminary evidence shows that a cognitive training could allow patients to improve and maintain their performance not only on the trained task, but also on a similar task. 相似文献
This article presents and discusses one of the most prominent inferential strategies currently employed in cognitive neuropsychology, namely, reverse inference. Simply put, this is the practice of inferring, in the context of experimental tasks, the engagement of cognitive processes from locations or patterns of neural activation. This technique is notoriously controversial because, critics argue, it presupposes the problematic assumption that neural areas are functionally selective. We proceed as follows. We begin by introducing the basic structure of traditional “location‐based” reverse inference (§1) and discuss the influential lack of selectivity objection (§2). Next, we rehearse various ways of responding to this challenge and provide some reasons for cautious optimism (§3). The second part of the essay presents a more recent development: “pattern‐decoding reverse inference” (§4). This inferential strategy, we maintain, provides an even more convincing response to the lack of selectivity charge. Due to this and other methodological advantages, it is now a prominent component in the toolbox of cognitive neuropsychology (§5). Finally, we conclude by drawing some implications for philosophy of science and philosophy of mind (§6). 相似文献
In this study, we use temporally aligned word embeddings and a large diachronic corpus of English to quantify language change in a data-driven, scalable way, which is grounded in language use. We show a unique and reliable relation between measures of language change and age of acquisition (AoA) while controlling for frequency, contextual diversity, concreteness, length, dominant part of speech, orthographic neighborhood density, and diachronic frequency variation. We analyze measures of language change tackling both the change in lexical representations and the change in the relation between lexical representations and the words with the most similar usage patterns, showing that they capture different aspects of language change. Our results show a unique relation between language change and AoA, which is stronger when considering neighborhood-level measures of language change: Words with more coherent diachronic usage patterns tend to be acquired earlier. The results support theories positing a link between ontogenetic and ethnogenetic processes in language. 相似文献
