Emotional events are thought to have privileged access to attention and memory, consuming resources needed to encode competing emotionally neutral stimuli. However, it is not clear whether this detrimental effect is automatic or depends on the successful maintenance of the specific emotional object within working memory. Here, participants viewed everyday scenes including an emotional object among other neutral objects followed by a free-recollection task. Results showed that emotional objects—irrespective of their perceptual saliency—were recollected more often than neutral objects. The probability of being recollected increased as a function of the arousal of the emotional objects, specifically for negative objects. Successful recollection of emotional objects (positive or negative) from a scene reduced the overall number of recollected neutral objects from the same scene. This indicates that only emotional stimuli that are efficient in grabbing (and then consuming) available attentional resources play a crucial role during the encoding of competing information, with a subsequent bias in the recollection of neutral representations.  相似文献

Effects of cognitive load, objective self‐awareness and time limits on the self‐regulation of performance speed and accuracy were investigated between procrastinators and non‐procrastinators. In experiment 1 chronic procrastinators completed fewer items (slow speed) and made more errors (less accuracy) than non‐procrastinators under high but not low cognitive load conditions when the time span was limited and brief. In experiment 2 chronic procrastinators performed slower than non‐procrastinators under a 2 second, but not under no limit, 1 second, or 4 second time limit conditions. Chronic procrastinators compared to non‐procrastinators also performed more slowly and made more performance errors under objective self‐awareness conditions regardless of the length of time. These experiments indicate that chronic procrastinators regulate ineffectively their performance speed and accuracy when they ‘work under pressure’ (defined by high cognitive load, objective self‐awareness, and imposed time limitations).

The present paper reports findings from a longitudinal study examining the development of English as foreign language learning in a sample of 86 Italian students tested at Grade 6 (mean age 11:3) and Grade 8 (mean age 13:3) . Two measures were examined: one relating to sustained learning ( i.e., English learning attainment), and one to short period development,(i.e., change in English proficiency). Different pattern of predictors were identified among L1 reading (speed and comprehension) and mathematics skills. The main findings indicated that calculation components of mathematics skills and reading comprehension predicted English learning attainments at Grade 8, whilst L1 reading speed at Grade 6 strongly predicted changes in English learning proficiency. The theoretical and empirical implications of the results are discussed in the specificity of a learning direction from a transparent L1 to a non‐transparent L2.

The Career Adapt-Abilities Scale (CAAS)-Italian Form consists of four 6-item scales, which measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. The 24-item CAAS-Italian Form is identical to the International Form 2.0. The factor structure was similar to the one computed for combined data from 13 countries. Internal consistency estimate for the four subscale and total scores was good. Concurrent validity evidence was collected on perceived internal and external barriers, breadth of interests, and quality of life. Correlations resulted as predicted and showed adaptability related negatively to perceived barriers and positively to breadth of interests and quality of life. As expected, analyses of variance showed that adolescents with higher adaptability perceive fewer barriers, express a broader range of interests, and report a higher quality of life.  相似文献

Due to the highly variable nature of predation risk, prey animals need to continuously collect information regarding the risk posed by predators. One question that ensues is how long to use this information for? An adaptive framework of predator-related information use predicted that certainty should influence the duration for which information regarding the threatening nature of a species is used in decision-making. It predicts that uncertainty contributes to the reduction in the duration of information use, due to the cost of displaying antipredator behaviours towards non-threatening species. Here, we test this prediction using repetition of conditioning events as a way to increase the certainty associated with the predatory nature of a novel salamander for woodfrog tadpoles. Tadpoles were conditioned 1, 2 or 4 times to recognize a novel salamander as a predator and subsequently tested for their response to the salamander 1?day or 11?days post-conditioning. We found that conditioning repetition did not affect the intensity with which tadpoles learned to respond to the salamander after 1?day. However, after 11?days, tadpoles with fewer conditionings responded to the salamander with a weaker intensity than those that received more conditionings. Our results provide support for the model prediction that an increase in the certainty associated with correctly identifying a predator leads to longer retention of the threat.  相似文献

The present study explored behavioral and eye-movement measures in unilateral neglect patients in response to online bisection task (unfilled gap line). Two different tasks supported the bisection performance, a pointing and a grasping strategy. It was explored whether these different strategies may influence subjects' behavioral and eye-movement measures in response to different segment features: segment length (from shorter to longer) and segment spatial dislocation (from right to left spatial location). Consistent spatial biases were found for both bisection responses, fixation count, and duration, as well as for the first fixation count in case of pointing task. An "extreme-left" gradient effect was suggested and discussed, with patients' behavioral and eye measures more impaired. On the contrary, the patients' performance overlaps with the controls' one in case a grasping task. The direct link of visual pointing and grasping strategy, respectively, with the two cortical ventral and dorsal pathways was adduced to explain our results.  相似文献

Within aquatic ecosystems, chemosensory cues provide valuable public information regarding the form and degree of risk, allowing prey to make informed behavioural decisions. Such cues, however, may vary in both relative concentration detected (i.e. ‘quantity’) and reliability of the information available (i.e. ‘quality’), leading to varying response patterns. Moreover, prey species are also known to exhibit consistent behavioural tactics towards managing risk (i.e. personality), possibly shaping their use of public information. Here, we present two experiments examining the potential interacting effects of personality and the quantity (Experiment 1) or quality (Experiment 2) of public information on the short-term predator avoidance responses of wild-caught Trinidadian guppies under semi-natural conditions. Our first experiment demonstrated that personality shaped responses to a high concentration of alarm cues (high risk), with shyer guppies exhibiting stronger antipredator responses than bolder guppies. When exposed to either low risk or stream water controls, personality had no effect on the intensity of response. Our second experiment demonstrated that personality again shaped the response to high concentrations of alarm cues (a known risk) but not to a novel chemosensory cue (tilapia odour). When exposed to the unknown novel cue, guppies exhibited a relatively high intensity antipredator response, regardless of personality. Combined, our results suggest that individual risk-taking tactics shape the use of public information in a context-dependent fashion.  相似文献

This study aimed to investigate psychosocial functioning and different dimensions of theory of mind (ToM) in people with bulimia nervosa (BN) and Eating Disorder Not Otherwise Specified‐BN type (EDNOS‐BN). Psychosocial functioning and ToM were assessed in a sample of young adult females, 16 BN and 16 EDNOS‐BN outpatients and 16 healthy controls (HCs). They were assessed using the Eating Disorder Inventory‐Symptom Checklist‐2 (EDI‐2 SC) for evaluating psychological traits associated with eating disorders; the Symptom Checklist‐90‐Revised (SCL‐90‐R) for evaluating psychopathological status; and the Theory of Mind Assessment Scale (Th.o.m.a.s.), a semi‐structured interview aimed at assessing a person's different dimensions of ToM. The BN and EDNOS‐BN groups exhibited worse performance than the control group on all dimensions of the SCL‐90‐R, and on all dimensions of the EDI‐2 SC. The only difference for perfectionism was that BN obtained higher scores than EDNOS‐BN group. Our results also revealed an impairment of third‐person and second‐order ToM in patients with bulimia (BN and EDNOS‐BN) with respect to control subjects. These preliminary data have important implications for future empirical work, in that they provide valuable information regarding the importance of investigating the various facets of ToM ability separately, in order to provide a more detailed profile of ToM functioning in the clinical samples.  相似文献

Numerous empirical studies have investigated the relationships between cardiovascular diseases (CVD) and patients’ psychological well-being, with a focus almost exclusively on its dark side. Very little is known on the impact of illness severity on both negative and positive indicators of patients’ well-being, as well as on the psychosocial variables that may mediate this association. Aim of the study was to investigate the impact of illness severity on depression as well as on health satisfaction and life satisfaction of patients undergoing a cardiovascular rehabilitation. It also aimed at testing the mediation of illness perception and self-efficacy beliefs in managing cardiac risk factors. The study involved 172 patients (mean age?=?66.43?years; SD?=?9.99?years; 76.2% men). Illness severity was measured in terms of left ventricular ejection fraction at discharge from the cardiology department, whereas all psychological dimensions were assessed one week later. Results showed significant relationships among illness severity, depression and health satisfaction that were fully mediated by illness perception and self-efficacy beliefs, but not significant relation between disease severity and life satisfaction (χ 2(1)?=?2.30, p?=?n.s.). Overall, findings underline the importance of working on illness perception and self-efficacy beliefs to contrast depression and to improve health and life satisfaction in patients with CVD.  相似文献
