Rapid acquisition of phonological alternations by infants

We explore whether infants can learn novel phonological alternations on the basis of distributional information. In Experiment 1, two groups of 12-month-old infants were familiarized with artificial languages whose distributional properties exhibited either stop or fricative voicing alternations. At test, infants in the two exposure groups had different preferences for novel sequences involving voiced and voiceless stops and fricatives, suggesting that each group had internalized a different familiarization alternation. In Experiment 2, 8.5-month-olds exhibited the same patterns of preference. In Experiments 3 and 4, we investigated whether infants' preferences were driven solely by preferences for sequences of high transitional probability. Although 8.5-month-olds in Experiment 3 were sensitive to the relative probabilities of sequences in the familiarization stimuli, only 12-month-olds in Experiment 4 showed evidence of having grouped alternating segments into a single functional category. Taken together, these results suggest a developmental trajectory for the acquisition of phonological alternations using distributional cues in the input.     

The psychology behind the masks: Psychological responses to the severe acute respiratory syndrome outbreak in different regions

Severe acute respiratory syndrome (SARS) was first reported in China, and spread to 29 regions, affecting over 8000 people worldwide. For the general public, the psychological impact of SARS may have been greater than the physical health danger of the disease. The present paper proposes the influence of psychological factors on people's cognitive, affective, and behavioral responses during the SARS outbreak. The various papers in this special issue of the Journal reveal how people have reacted during the SARS outbreak: People's general coping styles may be related to their health behavior during the outbreak. Cultural differences were evident in the perception of SARS, and individuals' perceptual styles may have influenced their ability to cope with the outbreak. The way in which individuals coped with SARS-related stressful events was different from their usual practices of managing daily stress. Individual differences in the adoption of preventive measures were related to the distinct susceptibility to several social-cognitive biases.     

Perceived aversiveness of recommended solution and locus of control as determinants of response to danger

As determined by their scores on Rotter's Locus of Control scale (Psychological Monographs, 1966, 80 (1, Whole No. 609)), internal and external subjects were exposed either to a high-, low-, or no-fear message on the dangers of exposure to a sunlamp. It was recommended to half the subjects in each condition that they apply a cream which was described as producing minimal skin irritation (low aversiveness), while half the subjects received recommendations to apply a cream described as producing considerable skin irritation (high aversiveness). It was predicted that (a) a high-fear message would be more effective than a low-fear message in getting subjects to use the cream, especially when the recommended behavior was perceived as low in aversivensss; and (b) a high-fear message would be more effective than a low fear message for subjects classified as internals. The second prediction was confirmed, and the first was tentatively supported. Results were interpreted in terms of the perceptual processes which may mediate the relationship between fear and action. The findings did not support the fear-drive model.     

Empirical Correlates of Cosmopolitan Orientation: Etiology and Functions in a Worldwide Representative Sample

Psychology has begun contributing to social theory by providing empirical measures of actually existing cosmopolitanism that complements more purely theoretical conceptions of the construct common in philosophy and sociology. Drawing from two waves of research on representative adult samples from 19 countries (N = 8740), metric invariance was found for the three factors of cosmopolitan orientation (COS): cultural openness (CO), global prosociality (GP), and respect for cultural diversity (RCD). In terms of etiology, among Wave 1 measures, the personality factor of agreeableness was the best predictor of the cosmopolitan factors of GP and RCD at Wave 2, whereas openness of personality best predicted CO. Wave 1 measures of education, political liberalism, and self-reported social status independently also explained a small amount of variance in COS. Functionally, COS was shown to predict less prejudice against immigrants, and more support for global civil society, even after controlling for social dominance orientation. All three COS factors independently predicted better attitudes towards immigrants. GP was the best predictor of trust in the United Nations, whereas RCD was the best predictor of support for environmental protection. The three-factor model of COS appears well-calibrated for assessing actually existing cosmopolitanism across cultures.     

Neuropsychology of Environmental Navigation in Humans: Review and Meta-Analysis of fMRI Studies in Healthy Participants

In the past 20 years, many studies in the cognitive neurosciences have analyzed human ability to navigate in recently learned and familiar environments by investigating the cognitive processes involved in successful navigation. In this study, we reviewed the main experimental paradigms and made a cognitive-oriented meta-analysis of fMRI studies of human navigation to underline the importance of the experimental designs and cognitive tasks used to assess navigational skills. We performed a general activation likelihood estimation (ALE) meta-analysis of 66 fMRI experiments to identify the neural substrates underpinning general aspects of human navigation. Four individual ALE analyses were performed to identify the neural substrates of different experimental paradigms (i.e., familiar vs. recently learned environments) and different navigational strategies (allocentric vs. egocentric). Results of the general ALE analysis highlighted a wide network of areas with clusters in the occipital, parietal, frontal and temporal lobes, especially in the parahippocampal cortex. Familiar environments seem to be processed by an extended temporal-frontal network, whereas recently learned environments require activation in the parahippocampal cortex and the parietal and occipital lobes. Allocentric strategy is subtended by the same areas as egocentric strategy, but the latter elicits greater activation in the right precuneus, middle occipital lobe and angular gyrus. Our results suggest that different neural correlates are involved in recalling a well-learned or recently acquired environment and that different networks of areas subtend egocentric and allocentric strategies.     

Belief-level markers of physical activity among young adult couples: Comparisons across couples without children and new parents

The health benefits of regular moderate–vigorous intensity physical activity (MVPA) are well established, yet young adults, particularly parents, often show declines in MVPA and may represent a critical population for intervention. Theory-based correlates used to guide future interventions are scant in this population. The purpose of this study was to examine theory of planned behaviour (TPB) belief-level constructs as correlates of directly assessed MVPA across cohorts of couples without children and with their first child over the initial 12?months. Participants were 238 adults (102 not expecting a child, 136 expecting first child) who completed baseline demographics, belief measures of the TPB and seven-day accelerometry, followed by assessments at 6 and 12 months. Results showed select medium-sized belief-PA correlations with sex and cohort interactions. Overall, women had larger affect-based behavioural belief associations with MVPA than men (e.g. PA relieves stress), and among new parents, mothers showed larger associations with control over MVPA than fathers. Mothers also had larger associations between control beliefs and MVPA compared to women without children (e.g. domestic duties, bad weather). Extremely high means and low variability on the behavioural beliefs show limited room for possible changes in intervention while control beliefs had low means suggesting room for change. Interventions targeting control among new mothers may be paramount for increasing MVPA, yet the TPB yielded less insight into the targets for promoting MVPA among young men.     

Processes Underlying Gender‐Role Flexibility: Do Androgynous Individuals Know More or Know How to Cope?

This research examined gender-role flexibility across a variety of stressful events, and tested two proposed hypotheses that explicate the processes underlying gender-role flexibility. The knowing-more hypothesis posits that androgynous individuals have a broad coping repertoire. The knowing-how hypothesis posits that androgynous individuals know how to cope according to changing situational characteristics. The coping responses of Chinese university students were assessed in both real-life (Study 1) and hypothetical (Study 2) stressful situations. Results revealed that androgynous participants, who were less depressed than others, were characterized by (a) cognitive astuteness in distinguishing among situational characteristics and (b) deployment of strategies that fit specific situational demands. Results supported the knowing-how hypothesis only.     

Imitation: is cognitive neuroscience solving the correspondence problem?

Imitation poses a unique problem: how does the imitator know what pattern of motor activation will make their action look like that of the model? Specialist theories suggest that this correspondence problem has a unique solution; there are functional and neurological mechanisms dedicated to controlling imitation. Generalist theories propose that the problem is solved by general mechanisms of associative learning and action control. Recent research in cognitive neuroscience, stimulated by the discovery of mirror neurons, supports generalist solutions. Imitation is based on the automatic activation of motor representations by movement observation. These externally triggered motor representations are then used to reproduce the observed behaviour. This imitative capacity depends on learned perceptual-motor links. Finally, mechanisms distinguishing self from other are implicated in the inhibition of imitative behaviour.     

Descartes' Dualism and Contemporary Dualism

After drawing a distinction between two kinds of dualism—numerical dualism (defined in terms of identity) and modal dualism (defined in terms of supervenience)—we argue that Descartes is a numerical dualist, but not a modal dualist. Since most contemporary dualists advocate modal dualism, the relation of Descartes' views to the contemporary philosophy of mind are more complex than is commonly assumed.
