The present study examines individual differences in the relationship between two core concepts of the self‐determination theory (SDT), namely satisfaction with the autonomy, competence, and relatedness need and motivation (autonomous vs. controlled). Based on the values component of SDT we hypothesised at least two different subpopulations with different need satisfaction–motivation patterns. Data from 349 Romanian volunteers revealed that two groups (or subpopulations) of volunteers can be distinguished, supporting our hypothesis. For the first and largest group, the pattern is in line with the SDT assumption that satisfaction of the autonomy and competence need has an effect on the autonomous forms of motivation. This group is in line with people endorsing intrinsic values. The second group of volunteers, however, revealed that satisfaction with the relatedness need links up with the controlled forms of motivation, and satisfaction of autonomy and competence needs does not predict autonomous motivation. This group is expected to favor extrinsic values. Both relationship patterns were further linked to work engagement and intention to quit, in order to shed light on the practical importance of the observed differences.  相似文献

The present study investigates the processing of presupposition accommodation. In particular, it concerns the processing costs and the time-course of accommodation as compared to presupposition satisfaction. Data collected in a self-paced word-by-word reading times experiment support three results. First, independently on the presupposition trigger in use, accommodation is costlier than satisfaction. Second, presupposition accommodation takes places immediately just as the trigger becomes available and proceeds incrementally during the sentence processing. Third, accommodated information is harder to be recalled. The results offer evidence for the on-line processing of presuppositions and, consistently with the traditional semantic framework, support the idea that, presuppositions are semantic properties encoded in the lexical meaning of the presupposition triggers.  相似文献

Two new procedures were employed to investigate the effects of semantic and grammatical gender on lexical access in Italian and to investigate the interaction of gender with other factors that are known to influence lexical access in other languages. The gender-monitoring task requires a conscious decision about the gender of each noun, whereas the word repetition task does not require explicit attention to gender. In both tasks, single words are presented out of context, under speeded conditions. Both procedures proved to be sensitive indices of word recognition, with reaction times that are closely tied to the point at which words can be uniquely identified (although some processing before and after the uniqueness point was seen). In both tasks, reaction times were strongly affected by phonological factors (e.g., length, number of syllables, and presence of frication on the initial consonant). Phonological transparency of gender marking had a reliable effect on gender monitoring but had no effect on word repetition, suggesting that explicit attention to gender may be a factor affecting utilization of this phonological cue. Semantic factors (including semantic gender) had no effect on performance. Frequency and age of acquisition had very small effects when other factors were controlled. Implications for current models of lexical access are discussed, with special reference to the role of gender.  相似文献

A growing body of research suggests that a history of neglect, abuse and institutionalization can negatively affect late-adopted children’s attachment representations, and that adoptive parents can play a key role in enabling adopted children to earn secure attachments. Still, only a few studies have explored the quality of caregiver–child interaction in adoptive families. The present study aimed at verifying both the concordance of attachment in adoptive dyads (mother–children and father–children) and the relationship between attachment representations and parent–child interaction. The research involved 20 adoptive families in which the child’s arrival had occurred between 12 to 36 months before the assessment, and where children were aged between 4.5 and 8.5 years. Attachment was assessed through the Adult Attachment Interview for parents and through the Manchester Child Attachment Story Task for children. The emotional quality of parent–child interaction was assessed trough the Emotional Availability Scales. Our results pointed out the presence of a relation between attachment representations of late-adopted children and their adoptive mothers (75%, K?=?0.50, p?=?.025). In addition, we found that both insecure children and mothers showed lower levels of EA than secure ones. Some explanations are presented about why, in the early post-adoption period, child attachment patterns and dyadic emotional availability seem to be arranged on different frameworks for the two parental figures.  相似文献

Recent results from our laboratory showed that, in fixed-target parallel search tasks, reaction times increase in a logarithmic fashion with set size, and the slope of this logarithmic function is modulated by lure-target similarity. These results were interpreted as being consistent with a processing architecture where early vision (stage one) processes elements in the display in exhaustive fashion with unlimited capacity and with a limitation in resolution. Here, we evaluate the contribution of crowding to our recent logarithmic search slope findings, considering the possibility that peripheral pooling of features (as observed in crowding) may be responsible for logarithmic efficiency. Factors known to affect the strength of crowding were varied, specifically: item spacing and similarity. The results from three experiments converge on the same pattern of results: reaction times increased logarithmically with set size and were modulated by lure-target similarity even when crowding was minimized within displays through an inter-item spacing manipulation. Furthermore, we found logarithmic search efficiencies were overall improved in displays where crowding was minimized compared to displays where crowding was possible. The findings from these three experiments suggest logarithmic efficiency in efficient search is not the result peripheral pooling of features. That said, the presence of crowding does tend to reduce search efficiency, even in “pop-out” search situations.  相似文献

In today’s advanced post-capitalist societies, consolidating identity with a view to acquiring adult roles is more complex than in the past. In Italy, the changes in the educational system are also associated with changes in the labor market characterized by lack of opportunity and instability. Therefore, young people on the threshold of university are discouraged from making long-term decisions and developing a coherent identity. The aim of the study was to explore what modalities Italian students adopt in order to cope with developmental tasks and how they proceed to negotiate and resolve identity-related concerns. The participants were 332 Italian students, balanced by gender, attending the first 2 years of university and aged 18–25. We used six self-report measures: Dimensions of Identity Development Scale; Identity Stage Resolution Index; Identity Distress Scale; Locus of Control Scale; Rosenberg Self-Esteem Scale; and Depressive Symptom Subscale and Anxiety Symptom Subscale. Participation was voluntary, and anonymity was guaranteed. Findings indicate that identity processes, identity distress and sense of adulthood are related dimensions. We find five different modalities of identity coping (clusters) that identify different subjects. These retained clusters have also an effect on psychosocial correlates. Results advance the literature linking identity, sense of adulthood and coping with developmental tasks in emerging adulthood. Findings also support previous literature suggesting that coping with identity during first years of university is an important target of prevention efforts aimed at improving academic performance and identification of developmental path, particularly for individuals who exhibit identity diffusion and distress.  相似文献

Midlife hypertension is associated with increased risk of cognitive impairment in later life. The association between blood pressure (BP) in older ages and cognition is less clear. In this study we provide estimates of between-person and within-person associations of BP and cognition in a population-based sample (N = 382) followed from age 70 across 12 occasions over 30 years. Between-person associations refer to how individual differences in BP relates to individual differences in cognition. Within-person associations refer to how individual and time specific changes in BP relate to variation in cognition. Hierarchical linear models were fitted to data from three cognitive measurements (verbal ability, spatial ability, and perceptual speed) while accounting for demographic and health-related covariates. We found consistent nonlinear between-person associations between diastolic BP (DBP) and cognition, such that both low (<75 mmHg) and high (>95 mmHg) pressure were associated with poorer cognition. Within-person decreases in systolic BP (SBP) and DBP were associated with decreases in perceptual speed. Notably, between-person and within-person estimates did not reveal similar associations, suggesting the need to separate the two effects in the analysis of associations between BP and cognition in old age.  相似文献

Research on the two fundamental dimensions of social judgment, namely warmth and competence, has shown that warmth has a primary and a dominant role in information gathering about others. In two studies we examined whether the sociability and morality components of warmth play distinct roles in such a process. Study 1 (N = 60) investigated which traits were mostly selected when forming impressions about others. The results showed that, regardless of the task goal, traits related to morality and sociability were differently processed. Furthermore, participants were more interested in obtaining information about morality than about sociability when asked to form a global impression about others. Study 2 (N = 98) explored the adoption of asymmetric/symmetric strategies when asking questions to make inferences on others. As predicted, participants adopted an asymmetrically disconfirming strategy on morality traits, while they looked for more symmetrical evidence on sociability or competence traits. Overall, our findings indicated a distinct and a dominant role of the moral component of warmth in the information‐gathering process. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

The hippocampus plays a significant role in spatial memory processing, with sex differences being prominent on various spatial tasks. This study examined sex differences in healthy adults, using functional magnetic resonance imaging (fMRI) in areas implicated in spatial processing during navigation of a virtual analogue of the Morris water-maze. There were three conditions: learning, hidden, and visible control. There were no significant differences in performance measures. However, sex differences were found in regional brain activation during learning in the right hippocampus, right parahippocampal gyrus, and the cingulate cortex. During the hidden condition, the hippocampus, parahippocampal gyrus, and cingulate cortex were activated in both men and women. Additional brain areas involved in spatial processing may be recruited in women when learning information about the environment, by utilizing external cues (landmarks) more than do men, contributing to the observed sex differences in brain activation.  相似文献

This study investigated the cognitive profile and the cerebral perfusion pattern in a highly educated 70 year old gentleman with posterior cortical atrophy (PCA). Visuo-perceptual abilities, spatial memory, spatial representation and navigation, visuo-spatial mental imagery, semantic and episodic-autobiographical memory were assessed. Regional cerebral blood flow (rCBF) was imaged with SPECT. Cognitive testing showed visual-perceptual impairment, apperceptive visual and landmark agnosia, topographical disorientation with way-finding deficits, impaired map learning and poor mental image generation. Semantic memory was normal, while episodic-autobiographical memory was impaired. Reduced rCBF was found mainly in the right hemisphere, in the precentral gyrus, posterior cingulate and middle temporal gyri, cuneus and precuneus, in the left superior temporal and lingual gyri and in the parahippocampus bilaterally. Hypoperfusion in occipito-parietal regions was associated with visuo-spatial deficits, whereas deficits in visuo-spatial mental imagery might reflect dysfunction related to hypoperfusion in the parahippocampus and precuneus, structures which are responsible for spatial and imagery processing. Dissociating performance between preserved semantic memory and poor episodic-autobiographical recall is consistent with a pattern of normal perfusion in frontal and anterior temporal regions but abnormal rCBF in the parahippocampi. The present findings indicate that PCA involves visuo-spatial imagery deficits and provide further validation to current neuro-cognitive models of spatial representation and topographical disorientation.  相似文献
