Semantic priming between words is reduced or eliminated if a low-level task such as letter search is performed on the prime word (the prime task effect), a finding used to question the automaticity of semantic processing of words. This idea is critically examined in 3 experiments with a new design that allows the search target to occur both inside and outside the prime word. The new design produces the prime task effect (Experiment 1) but shows semantic negative priming when the target letter occurs outside the prime word (Experiments 2 and 3). It is proposed that semantic activation and priming are dissociable and that inhibition and word-based grouping are responsible for reduction of semantic priming in the prime task effect. 相似文献

Perceptual adaptation to time-compressed speech was analyzed in two experiments. Previous research has suggested that this adaptation phenomenon is language specific and takes place at the phonological level. Moreover, it has been proposed that adaptation should only be observed for languages that are rhythmically similar. This assumption was explored by studying adaptation to different time-compressed languages in Spanish speakers. In Experiment 1, the performances of Spanish-speaking subjects who adapted to Spanish, Italian, French, English, and Japanese were compared. In Experiment 2, subjects from the same population were tested with Greek sentences compressed to two different rates. The results showed adaptation for Spanish, Italian, and Greek and no adaptation for English and Japanese, with French being an intermediate case. To account for the data, we propose that variables other than just the rhythmic properties of the languages, such as the vowel system and/or the lexical stress pattern, must be considered. The Greek data also support the view that phonological, rather than lexical, information is a determining factor in adaptation to compressed speech. 相似文献

Although temperament and personality traits could influence the development and course of eating disorders, only a few studies examined the similarities and differences in personality between anorexia and bulimia nervosa. We compared 72 patients with DSM-IV eating disorders and 30 healthy controls. Dimensions of personality and personality disorders were evaluated with the Eysenck's EPQ, Cloninger's TCI, and the SCID-II questionnaires. The rates of impulsivity and clinical features were evaluated using specific rating scales. A comorbid personality disorder was found in 61.8% of patients with eating disorder. Avoidant personality disorder appeared was relatively common in anorexia nervosa restricting type; borderline personality disorder was most frequent in bulimia nervosa and the binge eating-purging type of anorexia nervosa. From a dimensional perspective, anorexic patients presented high scores in the dimension of persistence. Higher harm avoidance and impulsivity was found in bulimic patients. The overall eating disorders group presented high scores in neuroticism and low scores in self-directedness. Eating disorder patients have heterogeneous features of temperament and personality traits. Cluster C personality disorders seem more common in anorexia nervosa restricting type and impulsive personality features are associated with bulimic symptoms. Impulsivity seems to be a key aspect of temperament of bulimic patients, whereas anorexic symptoms are linked to persistent temperament traits. 相似文献

Pictures of facial expressions of emotion are used in a wide range of experiments. The last decade has seen an increase in the number of studies presenting local sets of emotion stimuli. However, only a few existing sets contain pictures of Latin Americans, despite the growing attention emotion research is receiving in this region. Here we present the development and validation of the Universidad Nacional de Cordoba, Expresiones de Emociones Faciales (UNCEEF), a Facial Action Coding System (FACS)-verified set of pictures of Argentineans expressing the six basic emotions, plus neutral expressions. FACS scores, recognition rates, Hu scores, and discrimination indices are reported. Evidence of convergent validity was obtained using the Pictures of Facial Affect in an Argentine sample. However, recognition accuracy was greater for UNCEEF. The importance of local sets of emotion pictures is discussed. 相似文献

I will help you because we are similar: Quality of contact mediates the effect of perceived similarity on facilitative behaviour towards immigrants 下载免费PDF全文

This research aimed to analyse interpersonal behaviour towards immigrants by exploring related psychosocial variables such as intergroup similarity and quality of intergroup contact. A new interpersonal behavioural tendencies scale was developed. In Study 1, Spanish participants reported their willingness to take different actions towards a Moroccan (i.e. a devalued target, n = 132) or an Ecuadorian (i.e. a valued target, n = 138), perceived intergroup similarity and quality of intergroup contact. Multigroup confirmatory factor analysis identified the expected dimensions: active facilitation (AF), passive facilitation (PF), passive harm (PH) and active harm (AH). Participants reported less similarity, less pleasant contact, less AF and less PF, and more PH with respect to Moroccans relative to Ecuadorians. Quality of contact mediated the effect of perceived similarity on interpersonal behaviour (especially facilitative behaviour) towards immigrants. Study 2 (N = 134) confirmed that this mediation effect also applied to Romanian immigrants, and tested a serial mediation pathway, in which perceived similarity affected symbolic threat, which in turn affected quality of contact, which finally affected behaviour. Changing perceived intergroup similarity might be a way of improving the quality of contact with minority groups, and this would be expected to increase pro‐social behaviour towards such groups. 相似文献

The study of websites displaying methods of both physical self‐harm and suicide has become an important aspect of deliberate self‐injury and suicide research. However, little is known about contextual factors related to entering such sites. Using data from 3,567 respondents aged 15–30 in the US, UK, Germany, and Finland, we found that experiences of victimization are associated with entering pro‐self‐harm sites and pro‐suicide sites. Also, the victimization context had relevance, as online victimization was particularly related to pro‐self‐harm behavior. The findings suggest a need to organize more specific online support for the victims of violence and online aggression. 相似文献

Background and objectives: Anxiety disorders are the most common mental health problems during childhood and adolescence. This study examined the course of anxiety symptoms in early adolescents from the general population over three phases.Design: Prospective cohort study.Methods: Two hundred and forty-two participants (mean-age of 13.52) from a baseline sample of 1514 (mean-age of 10.23) were followed up three times. Of the 1514 children, those with emotional risk and controls without risk constituted the second-phase sample (n?=?562; mean-age of 11.25). The Screen for Child Anxiety Related Emotional Disorders-SCARED was administered in all three phases.Results: Fifty-six percent and 32% of respondents showed total scores above the SCARED cutoff point at one and three years follow-up, respectively. Eight percent showed fluctuating symptoms. Fifty-five percent of respondents showed high scores for any subtype of anxiety over three years. Social phobia and generalized anxiety symptoms were the most prevalent and persistent. Participants with persistent separation anxiety showed the highest co-occurrence with symptoms of other psychopathological disorders. Participants with persistent anxiety showed lower academic performance. Being male was a protective factor against persistence.Conclusions: The data support anxiety maintenance during early adolescence. Early adolescence is a critical period which may involve other serious academic, social, and family problems. 相似文献

It is better to smile to women: Gender modifies perception of honesty of smiling individuals across cultures 下载免费PDF全文

Social perception studies have revealed that smiling individuals are perceived more favourably on many communion dimensions in comparison to nonsmiling individuals. Research on gender differences in smiling habits showed that women smile more than men. In our study, we investigated this phenomena further and hypothesised that women perceive smiling individuals as more honest than men. An experiment conducted in seven countries (China, Germany, Mexico, Norway, Poland, Republic of South Africa and USA) revealed that gender may influence the perception of honesty in smiling individuals. We compared ratings of honesty made by male and female participants who viewed photos of smiling and nonsmiling people. While men and women did not differ on ratings of honesty in nonsmiling individuals, women assessed smiling individuals as more honest than men did. We discuss these results from a social norms perspective. 相似文献
