The issue of whether suicide can be a good death was separated into two different questions: (1) can suicide be an appropriate death, and (2) can suicide be a rational death? Several definitions of an "appropriate" death were proposed, and suicide was seen as potentially appropriate. Similarly, several criteria for rationality were proposed and…

The purpose of this study was to identify behavioral differences between children who dropped out of piano lessons and those who continued for 3 years. Two videotaped first-year lessons of 14 pairs of piano students were systematically observed to record the duration or frequency of occurrence of selected student and teacher behaviors. Students in…

The purpose of the present study was to investigate differences in neural information transmission between gifted and normal children involved in scientific hypothesis generation. To investigate changes in the amount of information transmission, the children's averaged-cross mutual information (A-CMI) of EEGs was estimated during their generation…

Student differences in learning mathematics are categorized under four different mathematical learning styles. The names of books providing examples on how mathematics teachers can differentiate their classroom instructions are mentioned.

This article presents the characteristics of the life-lines drawn by older Finnish men and women. The study was part of the Evergreen Project, Finland. Seventy-eight persons aged 83-87 participated in an interview, in which they were asked to draw a life-line. The life-line was drawn on a standardized sheet as a continuous line which showed the…

Adolescence is frequently described as a period of pervasive self-consciousness, but an age-related peak in adolescence is not consistently obtained, and higher self-consciousness in girls is frequently obtained but not predicted by theoretical accounts. Two cohorts of adolescents (N=393), initially assessed at 13 and 15, completed public and…

Both the special education and gifted education literature call for a differentiated curriculum to cater for the wide range of student differences in any classroom. Gardner's theory of multiple intelligences was integrated with the revised Bloom's taxonomy to provide a planning tool for curriculum differentiation. Teachers' progress in using the…

In contemporary psychology there is debate over whether individual differences in psychological constructs are stable over extended periods of time. The authors argue that it is impossible to resolve such debates unless researchers focus on patterns of stability and the developmental mechanisms that may give rise to them. To facilitate this shift…

This research used an individual differences approach to test Eagly and Wood's (1999) claim that sex differences in the characteristics that people prefer in mates reflect the tendency for men and women to occupy different social roles in a society. The study related the extent to which participants endorsed the traditional female gender role to…

Weekly cycles in emotion were examined by combining item response modeling and spectral analysis approaches in an analysis of 179 college students' reports of daily emotions experienced over 7 weeks. We addressed the measurement of emotion using an item response model. Spectral analysis and multilevel sinusoidal models were used to identify…

Children with autism not only display social impairments but also significant individual differences in social development. Understanding the source of these differences, as well as the nature of social impairments, is important for improved diagnosis and treatments for these children. Current theory and research suggests that individual…

Individuals are typically more likely to continue to interact with people if they have a positive impression of them. This article shows how this sequential sampling feature of impression formation can explain several biases in impression formation. The underlying mechanism is the sample bias generated when the probability of interaction depends…

Studies of autism typically adopt a factorial matched-groups design aimed at eliminating nonspecific factors such as mental retardation as explanations of performance on experimental tasks. This paper reviews the issues involved in designing such studies and interpreting their results and suggests that the best approach to matching may be to…

Speakers with autism spectrum disorders (ASD) show difficulties in suprasegmental aspects of speech production, or "prosody," those aspects of speech that accompany words and sentences and create what is commonly called "tone of voice." However, little is known about the perception of prosody, or about the specific aspects of…
