This paper highlights the development and testing of the Infant Movement Motivation Questionnaire (IMMQ), an instrument designed to evaluate qualities of infant characteristics that relate specifically to early motor development. The measurement development process included three phases: item generation, pilot testing and evaluation of acceptability and feasibility for parents and exploratory factor analysis. The resultant 27-item questionnaire is designed for completion by parents and contains four factors including Activity, Exploration, Motivation and Adaptability. Overall, the internal consistency of the IMMQ is 0.89 (Cronbach's alpha), with test–retest reliability measured at 0.92 (ICC, with 95% CI 0.83–0.96). Further work could be done to strengthen the individual factors; however it is adequate for use in its full form. The IMMQ can be used for clinical or research purposes, as well as an educational tool for parents. 相似文献

Two groups of 15-year-old girls, one Italian-Australian (IA, n = 60), and one Anglo-Australian (AA, n = 48), were compared on self-esteem and a wide range of measures associated with sex roles, including sex-role satisfaction, sex-role orientation, and assessment of and attitudes toward sex-role differentiation in the family and the culture. Self-esteem and sex-role satisfaction did not differ in the two groups. Nor were there differences in attitudes toward sex-role differentiation, even though cultural and familial differentiation were greater in the IA group and males were accorded relatively more value. However, the groups did differ in the pattern of variables associated with self-esteem and with these sex-role measures. In the more traditional IA subculture, girls' sex-role attitudes correlated with situational constraints. Unlike the AA girls, self-esteem was, in part, associated with stereotypic feminine attributes and preoccupations, and conformed to the androgyny model of well-being. In the AA group, sex-role attitudes and self-esteem were associated with perceptions of personal qualities valued in the broader, more egalitarian culture, such as intellectual ability and masculinity, thus confirming the masculinity model. 相似文献

An important debate in the reasoning literature concerns the extent to which inference processes are domain-free or domain-specific. Typically, evidence in support of the domain-specific position comprises the facilitation observed when abstract reasoning tasks are set in realistic context. Three experiments are reported here in which the sources of facilitation were investigated for contextualised versions of Raven's Progressive Matrices (Richardson, 1991) and non-verbal analogies from the AH4 test (Richardson & Webster, 1996). Experiment 1 confirmed that the facilitation observed for the contextualised matrices was in part due to extraneous aspects of commentaries originally intended to activate domainspecific processes. Experiments 2 and 3 indicated that the remainder of the facilitation for the matrices, and all of the facilitation for the analogies, could be explained by visual salience: Converting the item elements into realistic objects had enabled them and their transitions to be identified more easily. Hence, performance at simplified abstract items was as good as, or better than, at contextualised items. It is concluded that facilitation effects cannot be interpreted as showing that domain-specific processes constitute a self-contained system separate from domain-free processes. In turn, this means that domain-free processes cannot be dismissed as being unimportant for reasoning. 相似文献

Older adults have difficulty when executive control must be brought on line to coordinate ongoing behavior. To assess age-related alterations in executive processing, task-switching performance and event-related potential (ERP) activity were compared in young and older adults on switch, post-switch, pre-switch, and no-switch trials, ordered in demand for executive processes from greatest to least. In stimulus-locked averages for young adults, only switch trials elicited fronto-central P3 components, indicative of task-set attentional reallocation, whereas in older adults, three of the four trial types evinced frontal potentials. In response-locked averages, the amplitude of a medial frontal negativity (MFN), a component reflecting conflict monitoring and detection, increased as a function of executive demands in the ERPs of the young but not those of the older adults. These data suggest altered executive processing in older adults resulting in persistent recruitment of prefrontal processes for conditions that do not require them in the young. 相似文献
