Individual Differences in Infant Visual Attention: Recognition of Degraded Visual Forms by Four-Month-Olds

In 5 experiments, 4-month-old infants were tested for their ability to recognize degraded visual targets as a function of individual differences in fixation duration. Targets were degraded by removing 10% of the total contour either from vertices (vertex-absent) or from midsegments (vertex-present). Both qualitative and quantitative differences were found in long and short lookers' ability to recognize the degraded forms. Short-looking infants were able to recognize degraded forms in both vertex-absent and vertex-present conditions, but the vertex-absent discrimination was more difficult. Long-looking infants required longer familiarization times before showing evidence of recognition in the vertex-present condition, and were unable to recognize targets in which contour was removed at vertices. The findings are discussed within the framework of the persistence of early visual processing strategies, and reliance of long-looking infants on particular local elements in visual analysis.     

Genetic and environmental components of adolescent adjustment and parental behavior: a multivariate analysis

Adolescent adjustment measures may be related to each other and to the social environment in various ways. Are these relationships similar in genetic and environmental sources of covariation, or different? A multivariate behavior-genetic analysis was made of 6 adjustment and 3 treatment composites from the study Nonshared Environment in Adolescent Development, using 674 same-sex adolescent sibling pairs aged 9-11. Cholesky decompositions of the total covariance matrix yielded additive and nonadditive genetic, and shared and nonshared environmental matrices. Factor analyses led to 3 factors for all but shared environment. The first 2 factors resembled Neuroticism and Extraversion factors typically found for personality; the third factor, parental monitoring and control, appeared to have different associations in different matrices.     

The Thinking Curriculum

Over the past 20 years there has been growing interest in the idea of teaching thinking. This paper reviews the development of the idea worldwide, the supporting arguments and scepticism, the underlying constructivist psychological theories and the variety of methods and programmes used. A main distinction in approach is between those who advocate specific programmes, often based on skills analysis, and those who favour the infusion of thinking throughout the conventional subjects of the school or college curriculum. The balance of opinion supports the ‘thinking curriculum'; but this raises issues of domain‐specific knowledge and transfer. Recent work recognises the importance of social and affective, as well as cognitive, aspects in teaching thinking.     

Teacher self-assessment: A mechanism for facilitating professional growth

Self-assessment is a powerful technique for improving achievement. In this article we outline a theory of teacher change that links self-assessment by teachers to their professional growth. This theory provides avenues for peers and change agents to influence teacher practice. We apply the theory to change in mathematics teaching and report an explanatory case study in which use of the self-assessment tool, in combination with other elements, contributed to change in the instructional practice of a grade 8 mathematics teacher. Provision of a self-assessment tool contributed to teacher growth by: (1) influencing the teacher's definition of excellence in teaching and increasing his ability to recognize mastery experiences; (2) helping the teacher select improvement goals by providing him with clear standards of teaching, opportunities to find gaps between desired and actual practices, and a menu of options for action; (3) facilitating communication with the teacher's peer; and (4) increasing the influence of external change agents on teacher practice. The study argues that providing a self-assessment tool is a constructive strategy for improving the effectiveness of in-service provided it is bundled with other professional growth strategies: peer coaching, observation by external change agents, and focused input on teaching strategies     

Measuring the attitudes of human service professionals toward deafness

The Attitudes to Deafness Scale is a 22-item measure of attitudes toward people who are deaf designed for use with human service professionals. Attitude statements were generated from personal accounts by deaf people in the literature and from a focus group in which deaf people discussed their experience of hearing people's attitudes toward them. A 60-item scale was administered to a group of 121 clinical and forensic psychologists during their training. Item analysis was conducted to select items that effectively distinguished participants with a positive attitude from those with a negative attitude toward deaf people. The scale may be used in any context where a professional group comes into contact with people who are deaf.
