It is our position that a complete understanding of human intellectual development is of ultimate interest to researchers and of great import to society. In this article, we ask questions that reflect common themes seen in the debate regarding the nature and importance of general cognitive ability (i.e., the g factor), sources of individual and group differences, and the viability of arguments against g theory. We also examine questions reflecting aspects of these debates that are commonly ignored or misconstrued. Our goal is to help researchers and debaters continue or begin to ask clear, critical, and dispassionate questions about g that will stimulate productive research and promote informed public policy. 相似文献

Face construction by selecting individual facial features rarely produces recognisable images. We have been developing a system called EvoFIT that works by the repeated selection and breeding of complete faces. Here, we explored two techniques. The first blurred the external parts of the face, to help users focus on the important central facial region. The second, manipulated an evolved face using psychologically‐useful ‘holistic’ scales: age, masculinity, honesty, etc. Using face construction procedures that mirrored police work, a large benefit emerged for the holistic scales; the benefit of blurring accumulated over the construction process. Performance was best using both techniques: EvoFITs were correctly named 24.5% on average compared to 4.2% for faces constructed using a typical ‘feature’ system. It is now possible, therefore, to evolve a fairly recognisable composite from a 2 day memory of a face, the norm for real witnesses. A plausible model to account for the findings is introduced.

In recent years, there has been increasing interest in people with superior face recognition skills. Yet identification of these individuals has mostly relied on criterion performance on a single attempt at a single measure of face memory. The current investigation aimed to examine the consistency of superior face recognition skills in 30 police officers, both across tests that tap into the same process and between tests that tap into different components of face processing. Overall indices of performance across related measures were found to identify different superior performers to isolated test scores. Further, different top performers emerged for target‐present versus target‐absent indices, suggesting that signal detection measures are the most useful indicators of performance. Finally, a dissociation was observed between superior memory and matching performance. Super‐recognizer screening programmes hould therefore include overall indices summarizing multiple attempts at related tests, allowing for individuals to rank highly on different (and sometimes very specific) tasks. 相似文献

The present study aimed to test the reliability and validity of the Person Centred and Experiential Psychotherapy Scale–Young Person version (PCEPS-YP). This is a newly developed and adapted 9-item scale which aims to measure counsellor competences in, and adherence to, person-centred practice, when working with adolescents. Counselling practice was assessed for 19 counsellors by randomly selecting 20-min audio segments from 142 recorded counselling sessions. Audio material was independently rated by eight raters using the PCEPS-YP to produce an average adherence rating per counsellor. Scale reliability was assessed via interrater reliability and internal consistency testing. Convergent validity was tested using ratings from the observer-rated Barrett-Leonard Relationship Inventory (BLRI Obs 40), and the scale was subjected to exploratory factor analysis. Results showed a high degree of internal consistency within raters (α = 0.95), marginally acceptable reliability across grouped raters (α = 0.58) and weaker reliability between pairs of raters (α = 0.50). Exploratory factor analysis revealed one strong factor for the scale with no subscales. Small-to-moderate correlations existed between the PCEPS-YP and the BLRI subscales and mean total score (rs = .12 to .40). Our findings suggest that the PCEPS-YP has potential as an effective, reliable and valid tool for assessing competence and adherence in person-centred practice with young people, both for research and for clinical purposes. However, training procedures need to be established that can enhance interrater reliability, and more evidence of convergent validity is needed. 相似文献

Children must describe maltreatment coherently for their testimony to be influential in court. We know little about how well children with intellectual disabilities (CWID) describe their experiences relative to typically developing (TD) children, despite CWID's vulnerability to maltreatment. We investigated children's reports of an experienced event and compared coherence in CWID (mild to moderate impairment: 7–11 years) with TD children matched for mental (4–10 years) or chronological age (7–11 years). All children included important markers of narrative coherence in their reports. Children with lower mental ages, particularly those with an intellectual disability, included fewer markers of narrative coherence in their reports than children with higher mental ages. Individual markers of narrative coherence, particularly recall of content, predicted accuracy of testimony and resistance to suggestion even when disability and mental age were taken into account. These findings highlight the importance of helping children to describe their experiences coherently. 相似文献

Set‐shifting refers to a process of cognitive control which is shown through flexible behavioural adaptation to changes in task parameters or demands, such as the switching of an explicit rule (extra‐dimensional rule shifting) or the reversal of a reinforcement‐contingency (reversal‐learning). Set‐shifting deficits are widely documented in specific neuropsychological disorders, but seldom investigated in relation to normally‐occurring individual differences. In a sample of healthy adults (N=78, 28% male), we demonstrate that Working Memory and trait Psychoticism have independent involvement in extra‐dimensional rule shifting as measured using an analogue of the Wisconsin Card Sorting Test. Only Psychoticism, however, was involved in reversal‐learning, as assessed using a recent modification of the Iowa Gambling Task. Individual differences in extra‐dimensional rule shifting were explained in terms of rule abstraction speed, while individual differences in reversal‐learning were explained in terms of response perseveration. These results clarify component processes in different forms of set‐shifting, and highlight the role of individual differences, especially personality, in cognitive control. 相似文献
