It has recently been shown that the cost associated with switching tasks is eliminated following ‘no-go’ trials, in which
response selection is not completed, suggesting that the switch cost depends on response selection. However, no-go trials
may also affect switch costs by interfering with the effects of task preparation that precede response selection. To test
this hypothesis we evaluated switch costs following standard go trials with those following two types of non-response trials:
no-go trials, for which a stimulus is presented that indicates no response should be made (Experiment 1); and cue-only trials
in which no stimulus is presented following the task cue (Experiment 2). We hypothesized that eliminating no-go stimuli would
reveal effects of task preparation on the switch cost in cue-only trials. We found no switch cost following no-go trials (Experiment
1), but a reliable switch cost in cue-only trials (i.e., when no-go stimuli were removed; Experiment 2). We conclude that
no-go trials can modulate the switch cost, independent of their effect on response selection, by interfering with task preparation,
and that the effects of task preparation on switch cost are more directly assessed by cue-only trials. 相似文献

Debates concerning the types of representations that aid reading acquisition have often been influenced by the relationship between measures of early phonological awareness (the ability to process speech sounds) and later reading ability. Here, a complementary approach is explored, analyzing how the functional utility of different representational units, such as whole words, bodies (letters representing the vowel and final consonants of a syllable), and graphemes (letters representing a phoneme) may change as the number of words that can be read gradually increases. Utility is measured by applying a Simplicity Principle to the problem of mapping from print to sound; that is, assuming that the "best" representational units for reading are those which allow the mapping from print to sounds to be encoded as efficiently as possible. Results indicate that when only a small number of words are read whole-word representations are most useful, whereas when many words can be read graphemic representations have the highest utility. 相似文献

Clinical trials exploring the effectiveness of counseling and psychotherapy in treatment of depression in school‐age youth composed this meta‐analysis. Results were synthesized using a random effects model for mean difference and mean gain effect size estimates. No effects of moderating variables were evident. Counseling and psychotherapy are effective for treatment of depression in school‐age youth both at termination and follow‐up, and in school and nonschool settings. 相似文献

Employing Self-Determination Theory (Deci & Ryan, 1985) as a theoretical framework, this study examined psychological need satisfaction and motivational regulations as predictors of psychological and behavioural outcomes in exercise referral (ER). ER patients (N?=?293; mean age 54.49) completed the measures of motivational regulations, psychological need satisfaction, health-related quality of life, life satisfaction, anxiety, depression and physical activity at entry, exit and 6 months following the end of a supervised exercise programme. Change in (Δ) intrinsic motivation during the scheme significantly predicted adherence and Δ habitual physical activity. Δ psychological need satisfaction from entry to exit significantly predicted Δ habitual physical activity from exit to 6-month follow-up. Δ psychological need satisfaction significantly predicted Δ motivational regulation and Δ psychological outcomes. Contrary to expectations, Δ self-determined regulation did not significantly predict Δ psychological outcomes during the structured part of the scheme, however, it did significantly predict Δ in psychological outcomes from exit to 6-month follow-up. These findings expand on cross-sectional research to demonstrate that psychological need satisfaction during supervised ER longitudinally predicts motivational regulation and psychological outcomes up to 6 months after a structured programme. 相似文献

Genetic testing for BRCA1/2 mutations associated with hereditary breast and ovarian cancer reveals significant risk information about one's chances of developing cancer. It is important to study communication processes in families where members are undergoing genetic testing because the information received is crucial not just to the individual concerned but also to other members of the biological family. This study investigates family communication of BRCA1/2 test results from both the informants' and recipients' perspectives. A total of 10 female patients and 22 of their relatives were interviewed. Patients' and their relatives described feelings of responsibility for sharing genetic information within the family to enable others to reduce their risks of developing cancer. However, there were limits to an individuals' responsibility once key family members had been informed, who then had to take responsibility for continuing dissemination of information. Whilst there was an implicit responsibility to inform the family of a mutation, information was edited or withheld in the best interest of relatives, dependent upon their perceived emotional readiness, resilience and current life stage and circumstances. The pre-existing family culture and the impact previous cancer diagnoses had upon the family also influenced the process of communication. Findings are discussed in relation to extant literature and implications for clinical practice are considered. 相似文献

Previous studies have implicated attachment and disturbances in romantic relationships as important indicators for Borderline Personality Disorder (BPD). The current research extends our current knowledge by examining the specific associations among attachment, romantic relationship dysfunction, and BPD, above and beyond the contribution of emotional distress and nonromantic interpersonal functioning in two distinct samples. Study 1 comprised a community sample of women (N = 58) aged 25-36. Study 2 consisted of a psychiatric sample (N = 138) aged 21-60. Results from both Study 1 and Study 2 demonstrated that (1) attachment was specifically related to BPD symptoms and romantic dysfunction, (2) BPD symptoms were specifically associated with romantic dysfunction, and (3) the association between attachment and romantic dysfunction was statistically mediated by BPD symptoms. The findings support specific associations among attachment, BPD symptoms, and romantic dysfunction. 相似文献

Field implementation of double‐blind sequential lineups has prompted a question about the impact on eyewitness decisions of an explicit not‐sure response option. In this laboratory study, a video crime was viewed by 378 participants who then attempted to identify the culprit from a six‐person sequential or simultaneous‐format lineup that either included or did not include the culprit. Witnesses were provided either dichotomous forced‐choice (FC) response categories (yes/no) or a not‐sure option as one of three response categories (yes/no/not‐sure). The not‐sure option (NSO) significantly decreased witness choosing compared to the FC condition but only for sequential lineups. Both correct identifications and false alarms decreased. Diagnosticity was greatest for a sequential lineup with a NSO. The results suggest a criterion decision shift for witnesses who view a sequential lineup with a not‐sure response option.

This article considers the contribution of the Mindolo Ecumenical Foundation to the political and socio‐economic development of Zambia. First, the introduction and growth of Christianity in the mining areas of the Copperbelt are explored. Next, the article traces the formation and development of the Mindolo Ecumenical Foundation. In the third place, it analyzes the role played by the Mindolo Ecumenical Foundation in the politics and development of Zambia during the first decades of its formation, including its participation in Zambia's struggle for independence. After political independence, the foundation continued to fulfil a major part in facilitating reconciliation between blacks and whites. The article argues that the participation of the church in God's mission in the world cannot be divorced from socio‐economic and political realities. 相似文献

Religious groups often rely on a registration process to receive the legal status needed to operate openly. Yet, the registration process has become a recent source of controversy. This research uses case studies, trend data from three global collections, and fixed effects models using 19 waves of data to test for the consequences of introducing registration requirements within a nation. The case studies help us to understand the controversies and to identify how registration requirements have been used to increase restrictions on religions in the past, while the trend data document the increasing use of these requirements for discriminating against religions. Finally, the fixed effects models find that introducing registration requirements within a nation was followed by increased religious restrictions, especially for minority religions. 相似文献
