The origins and ends of giftedness

Five issues about giftedness are discussed. First, the origins of giftedness are explored. The view that giftedness is entirely a product of training is critiqued. There is indirect evidence for atypical brain organization and innate talent in gifted children: Many gifted children and savants have enhanced right-hemisphere development, language-related difficulties, and autoimmune disorders. Second, the intense motivation of gifted children is discussed. Third, it is argued that gifted children have social and emotional difficulties that set them apart. Fourth, evidence for the often uneven cognitive profiles of such children is presented. Finally, the relationship between childhood giftedness and "domain" creativity in adulthood is discussed. Few gifted children go on to become adult creators because the skills and personality factors required to be a creator are very different from those typical of even the most highly gifted children.     

Acquired ‘theory of mind'' impairments following stroke

The ability to attribute thoughts and feelings to self and others (‘theory of mind') has been hypothesised to have an innate neural basis and a dedicated cognitive mechanism. Evidence in favour of this proposal has come from autism; a brain-based developmental disorder which appears to be characterised by impaired theory of mind, despite sometimes good general reasoning skills/IQ. To date no case of specific acquired theory of mind impairment has been reported. The present study examined theory of mind in adults who had suffered right hemisphere stroke, a group known to show pragmatic and social difficulties. In one study using story materials and two using cartoons, patients' understanding of materials requiring attribution of mental states (e.g. ignorance, false belief) was significantly worse than their understanding of non-mental control materials. Data from healthy elderly subjects, and a small group of left hemisphere patients (who received the tasks in modified form), suggest that this impairment on mental state tasks is not a function of task difficulty. The findings support the notion of a dedicated cognitive system for theory of mind, and suggest a role for the healthy right hemisphere in the attribution of mental states.     

Masked and unmasked priming in schizophrenia

Dehaene et al. (2003) showed an absence of conscious, but not masked, conflict effects when patients with schizophrenia performed a number-categorisation priming task. We aimed to replicate these influential results using a different word-categorisation priming task. Counter to Dehaene et al.’s findings, 21 patients and 20 healthy controls showed similar congruence effects for both masked and visible primes. Within patients, a reduced congruence effect for visible primes associated with longer duration of illness and more severe behavioural disorganisation. Patients, unlike controls, were no slower to respond to targets that followed visible compared to masked primes. Conscious conflict effects on priming tasks are not universally reduced in schizophrenia but may associate with chronicity and behavioural disorganisation. That patients were no slower when the preceding primes were clearly visible accords with evidence elsewhere that information processing in schizophrenia is driven more by immediate conscious experience and constrained less by prior events.     

Citizen virtues in a technological order

Contemporary philosophical discussions about technology mirror a profound distance between technical practice and moral thought. I consider the origins of this gap as reflected in both ancient and modern writings. The philosopher's version of technocracy ‐ rushing forward with the analysis of moral categories in the hope that policy‐makers or the public will find them decisive ‐ does nothing to bridge this gap and is, therefore, a forlorn strategy. The trouble is not that we lack good arguments and theories, but rather that modern politics does not provide appropriate roles and institutions in which the activity of defining the common good in technology policy is a legitimate project. I find glimmerings of an alternative practice in the ‘Scandinavian approach’ to democratic participation in technological design.     

How children use drawing to regulate their emotions

We examined two ways in which drawing may function to elevate mood in children—venting (expressing negative feelings) and distraction (expressing something unrelated to the negative feelings). We examined the effectiveness of drawing as an emotion regulator when drawing is used to vent versus distract (Study 1) and tested whether the effects found are specific to the activity of creating one's own drawing or generalisable to a drawing activity in which children had to copy another's drawing (Study 2). To induce a negative mood, we asked children to think of a disappointing event. Mood was assessed before and after the assigned activity. In both studies, mood improved significantly more in the distract than in the vent or copy condition. Study 1 demonstrates that drawing improves mood in children via distraction and not via venting. Study 2 demonstrates that this effect is specific to a drawing task in which an image is freely constructed. When a copying task is used, the effect disappears.     

The mathematical abilities of children with cochlear implants

Research has shown that cochlear implants give rise to improvements in speech recognition and production in children with profound hearing loss but very few studies have explored mathematical abilities in these children. The current study compared the mathematical abilities of 24 children with cochlear implants (mean age 10 years 1 month) to a control group of 22 hearing children (mean age 9 years 8 months). The math questions were categorized into questions that tapped into arithmetic or geometrical reasoning. It was predicted that the cochlear implant group would perform below the hearing group on the arithmetic questions but not the geometrical reasoning questions. Unexpectedly, the results showed that the cochlear implant group performed significantly below the hearing group on both types of math questions, but that this difference was mediated by language skill as assessed by vocabulary knowledge. The clinical implications of these results and possible future research results are considered.     

A laboratory analogue of mirrored-self misidentification delusion: The role of hypnosis,suggestion, and demand characteristics

Mirrored-self misidentification is the delusional belief that one’s own reflection in the mirror is a stranger. In two experiments, we tested the ability of hypnotic suggestion to model this condition. In Experiment 1, we compared two suggestions based on either the delusion’s surface features (seeing a stranger in the mirror) or underlying processes (impaired face processing). Fifty-two high hypnotisable participants received one of these suggestions either with hypnosis or without in a wake control. In Experiment 2, we examined the extent to which social cues and role-playing could account for participants’ behaviour by comparing the responses of 14 hypnotised participants to the suggestion for impaired face processing (reals) with those of 14 nonhypnotised participants instructed to fake their responses (simulators). Overall, results from both experiments confirm that we can use hypnotic suggestion to produce a compelling analogue of mirrored-self misidentification that cannot simply be attributed to social cues or role-playing.     

Conceptualizations of respect: qualitative and quantitative evidence of four (five) themes

Respect is a term used frequently in the vernacular and psychological literature. However, frequency of use has not yielded a coherent body of psychological research on the topic, perhaps because of its elusive and contextual nature. Examining the divergent literature on respect yields 4 general themes in how it is conceptualized: (a) social rules, (b) equality, (c) caring, and (d) social power. In this study, the author used qualitative and quantitative assessment to explore the soundness of these themes. The 4 themes emerged in each of the different methods, and there was evidence of convergence of the themes across methods. A 5th unexpected theme, personal attributes, was revealed in the qualitative measures. This study provides an empirical foundation for acknowledging the complexity and potential importance of respect. Understanding the thematic variability in how respect is conceptualized will improve research, theory, and application.
