The Identification of Early Risk Factors for Severe Emotional Disturbances and Emotional Handicaps: An Epidemiological Approach

Epidemiological methodology is used to examine the relationship between early childhood risk factors and future identification as having a Severe Emotional Disturbance or as having an Emotional Handicap (SED/EH) at age 13. Data were obtained from 1979/1980 Florida birth records that were electronically linked with 1992/1993 Florida school records. An epidemiological perspective was chosen due to its ability to model both individual and community-level risk. In regards to increasing an individual's risk of SED/EH, two factors, gender (being male) and low maternal education (mother not completing high school at the time of the child's birth), were found to have particularly strong effects. When examining effects of these risk factors upon overall rates of SED/EH in the community, maternal education and marital status (being unmarried at the time of the child's birth) were associated with a large proportion of the cases. Health/biological markers were moderately associated with SED/EH on the individual level, but were related to a relatively small percentage of cases in the population. In addition, effects varied based upon ethnic/cultural heritage. Researchers are encouraged to consider using an epidemiological perspective and its potential utility in the field of community psychology and public policy is discussed.     

Female attractiveness and eating disorders: Do children's television commercials play a role?

The differential rate of eating disorders in males and females has been partially attributed to gender socialization. Media influences, even in children's programming, may contribute to the greater emphasis on physical attractiveness for girls compared to boys. Commercials from Saturday morning cartoon programming were analyzed for the number of male/female main and supporting characters, sex of narrator, sex of intended consumer, and appearance enhancement of person, doll, or animal. A majority of the commercials (60.6%) were for food products. Chi-square comparisons revealed significantly more male than female main characters and narrators in these commercials. Of those commercials (13.8%) scored for appearance enhancement, all male/female chi-square comparisons were significant with more female supporting characters, female main characters, female narrators, and female consumers. With the combined emphases on food and, for girls, on appearance, support for possible influences of commercials in eating disorders is noted.     

Who Started This? Investigating Different Sources of Organizational Change

This study explored whether organizational change had differential effects on perceptions of group leadership and group morale, depending on the source of the change activity. Data on work group leadership and morale was collected in two waves of an employee survey, and data on change activities were collected in the second wave of the survey. When leaders outside of a work group initiated change, employees reported more negative perceptions of their work group leader. However, when the work group leader initiated change, perceptions of that leader tended to be more positive. Finally, change activities initiated by group members did not influence perceptions of work group leadership, but were associated with improved work group morale.     

Spirituality in adolescence and young adulthood: A method for a qualitative study

This paper discusses an ongoing research project on contemporary forms of youth and young adult spirituality, highlighting issues in the history and definition of spirituality and in development of appropriate qualitative methods of investigation. Previous research on the topic has been bedevilled by difficulties of definition. 'Spirit' and 'spirituality' have a long history in both philosophy and religion and surviving senses of the terms include both religious and non-religious meanings. This paper suggests that 'lexical' definitions based on usage prove unwieldy because of widely varying and conflicting contents. Only a 'stipulative' definition will serve to provide a research project with a clear focus; our definition of spirituality as 'a conscious way of life based on a transcendent referent' is explained and defended. Next, we outline the distinctive features of our methodology: no direct mention of the term spirituality, an emphasis on personal narration and the use of evocative techniques. We conclude by outlining the 10 dimensions of spirituality which we have developed from our initial investigations.     

Sense of meaning and academic performance: A brief report

This study examined sense of meaning and academic performance among a sample of South African university students (n = 210, mean age = 19.49, SD = 1.99, female = 54.29%). Data on meaning were collected using the Purpose in Life Test. End of semester marks served as the academic attainment measure. Simple regression analysis with post-hoc independent-samples t-tests revealed that meaning predicts academic performance. No significant differences between genders emerged from the data. Sense of meaning is an important factor in supporting students to enhance their academic performance.     

Neural mechanisms of social influence

The present investigation explores the neural mechanisms underlying the impact of social influence on preferences. We socially tagged symbols as valued or not – by exposing participants to the preferences of their peers – and assessed subsequent brain activity during an incidental processing task in which participants viewed popular, unpopular, and novel symbols. The medial prefrontal cortex (mPFC) differentiated between symbols that were and were not socially tagged – a possible index of normative influence – while aspects of the striatum (the caudate) differentiated between popular and unpopular symbols – a possible index of informational influence. These results suggest that integrating activity in these two brain regions may differentiate objects that have become valued as a result of social influence from those valued for non-social reasons.     

An investigation into the temporal dimension of the Mozart effect: evidence from the attentional blink task

In the present study, we examined whether the 'Mozart effect' would influence participants' temporal attention using a visual attentional blink (AB) task that provides a reliable measure of the temporal dynamics of visual attention. The 'Mozart effect' refers to the specific claim that listening to Mozart's Sonata for Two Pianos in D Major, K.448 can improve the performance in spatio-temporal tasks. Participants had to try and identify two target digits (in their correct order of presentation) presented amongst a stream of distractor letters in three different conditions (presented in separate blocks of trials): while listening to the Mozart sonata played normally, while listening to the same Mozart sonata played in reverse, and while in silence. The results showed that the participants were able to detect the second target (T2) significantly more accurately (given the correct detection of the first target, T1) in the AB stream when the Mozart sonata was played normally than in either of the other two conditions. Possible explanations for the differential effects of Mozart's music being played normally and in reverse and potential confounds in previous studies reporting a facilitatory 'Mozart effect' are discussed. Our results therefore provide the first empirical demonstration supporting the existence of a purely temporal component to the 'Mozart effect' using a non-spatial visual AB task.
