Modality effects in the coding reproduction of rhythms

The temporal coding assumption is that time of presentation is coded more accurately for auditory events than for visual events. This assumption has been used to explain the modality effect, in which recall of recent auditory events is superior to recall of recent visual events. We tested the temporal coding assumption by examining the coding and reproduction of quintessentially temporal stimuli-rhythms. The rhythms were produced by sequences of short and long auditory stimuli or short and long visual stimuli; in either case, the task was to reproduce the temporal sequence. The results from four experiments demonstrated reproduction of auditory rhythms superior to that of visual rhythms. We conclude that speech-based explanations of modality effects cannot accommodate these findings, whereas the findings are consistent with explanations based on the temporal coding assumption.     

Autonomy as Second Nature: On McDowell's Aristotelian Naturalism

The concept of second nature plays a central role in McDowell's project of reconciling thought's external constraint with its spontaneity or autonomy: our conceptual capacities are natural in the sense that they are fully integrated into the natural world, but they are a second nature to us since they are not reducible to elements that are intelligible apart from those conceptual capacities. Rather than offering a theory of second nature and an account of how we acquire one, McDowell suggests that Aristotle's account of ethical character formation as the acquisition of a second nature serves as a model that can reassure us that thought's autonomy does not threaten its naturalness. However, far from providing such reassurance, the Aristotelian model of second nature actually generates an anxiety about how the acquisition of such autonomous conceptual abilities could be possible.     

Sense of Time and Executive Functioning in Children and Adults

A number of patient studies suggest that impairments in frontal lobe functions are associated with disorders in temporal information processing. One implication of these findings is that subjective experience of time should be related to executive functions regardless of etiology. In two experiments, we examined sense of time in relation to components of executive functioning in healthy children and adults. In Experiment 1, children between 8 to 12 years completed six experimental tasks that tapped three components of executive functioning: inhibition, updating, and mental shifting. Sense of time was examined in a duration judgment task in which participants reproduced stimulus durations between 4 to 32 s. In Experiment 2, adult participants completed the time reproduction task under varying concurrent task demands. Both experiments showed selective effects in that time reproduction errors were related to the inhibition and updating, but not to the shifting, components of executive functioning. However, the observed effects were modulated by task demands and age-related differences in cognitive competence. We conclude that individual differences in executive functioning are only weakly related to time reproduction performance in healthy children and adults.     

A comparative review of total family functioning measures

Abstract

Three categories of instruments or methods have been used to assess family functioning: unstandardized measures of total family functioning; instruments which measure family subsystems or unitary processes; and standardized total family assessment procedures. Six methods, comprising the standardized total family functioning category, are reviewed and compared. It is concluded that methods of total family assessment are nearing the formation of a family systems paradigm, although the psychometric qualities of the instruments lag behind theoretical development. Recommendations are made for further development of procedures to assess family systems.     

Toddlers' responsive imitation predicts preschool-age conscience

Imitation has long been considered a mechanism for the development of conscience. Despite the central role of imitation in theories of moral internalization, the prediction from imitation to moral behavior has not been tested using an individual differences approach. In a longitudinal design, we examined whether individual differences in toddlers' responsive imitation predict preschool-age conscience. Mothers modeled actions for their children to imitate, and both matching behavior and motivation were observed at 14 and 22 months of age. We also measured preschool conscience by observing children's internalized conduct and guilt at ages 33 and 45 months. Imitation measures consistently predicted conscience variables. These relations were strengthened by aggregation across measures and times of assessment. Motivation and matching behavior each contributed independent variance in predicting preschool-age conscience. Results are consistent with the claim that responsive imitation reflects a general receptive stance to parents' guidance, and with both neopsychoanalytic and social cognitive views of imitation's importance in early moral development.     

A comparison of acceptance- and control-based strategies for coping with food cravings: an analog study

The present study utilized an analog paradigm to investigate the effectiveness of two strategies for coping with food cravings, which was theorized to be critical to the maintenance of weight loss. Ninety-eight undergraduate students were given transparent boxes of chocolate Hershey's Kisses and instructed to keep the chocolates with them, but not to eat them, for 48 h. Before receiving the Kisses, participants were randomized to receive either (a) no intervention, (b) instruction in control-based coping strategies such as distraction and cognitive restructuring, or (c) instruction in acceptance-based strategies such as experiential acceptance and defusion techniques. Measures included the Power of Food Scale (PFS; a measure of psychological sensitivity to the food environment), self-report ratings of chocolate cravings and surreptitiously recorded chocolate consumption. Results suggested that the effect of the intervention depended on baseline PFS levels, such that acceptance-based strategies were associated with better outcomes (cravings, consumption) among those reporting the highest susceptibility to the presence of food, but greater cravings among those who scored lowest on the PFS. It was observed that craving self-report measures predicted chocolate consumption, and baseline PFS levels predicted both cravings and consumption. Results are discussed in terms of the implications for weight loss maintenance strategies.     

Agonistic behaviour and bite wound patterns in wild water voles (Arvicola terrestris L.)

Intra‐specific aggression was investigated in a wild colony of Water voles between 1999 and 2004 in South Wales, UK. The occurrence and location (i.e. on the head, neck, body or tail) of bite wounds were recorded for adult and juvenile male and female voles. The greatest (33%) incidence of bite wounds were recorded on juvenile females and the lowest (18%) in adult females. Seasonal analysis of wound data in adults revealed that females were more likely to be bitten during the breeding season whereas bite patterns in males did not vary seasonally. Analysis of bite pattern topography revealed that most Water voles seemingly attempt to bite vulnerable target areas of the body (namely the head and tail). This is in contrast with studies on rats and mice where competitive forms of attack (particularly involving males) largely avoid these areas of the attacked animal's body. Targeting vulnerable areas is normally a characteristic of defensive modes of attack. Patterns of bite topography and agonistic behaviour in this species seem to reflect competitive interactions between individuals, particularly between territorial females and their female offspring, over access to essential resources.

Viewing imitation as child responsiveness: a link between teaching and discipline domains of socialization

The authors observed 106 children's imitation and responses to maternal control at 14 and 22 months. Imitation was observed in a teaching task in which mothers modeled 3 standard pretend-play sequences. Responses to control were observed in typical discipline contexts. Girls imitated more than boys. Responsive imitation measures were coherent and longitudinally stable and correlated significantly with responsiveness to maternal control. The authors propose that a young child's willingness to imitate his or her parent in a teaching context and to comply in a control context both reflect a responsive or receptive stance toward parental socialization. The consistency of children's responsiveness across contexts has implications for both sociomoral and cognitive development.
