The control of food-caching behavior by Western scrub-jays (Aphelocoma californica)

Western scrub-jays (Aphelocoma californica) did not show extinction when caching behavior was never rewarded and they had no choice of where to cache the food. However, when the jays had the choice of caching items in 2 different locations or during 2 successive episodes, and only 1 of each was always rewarded at recovery, they rapidly learned to cache in the rewarded location or episode. When the jays had learned during training trials that their caches were always moved to 1 of 2 locations they did not cache in, then on the test trial they cached in the location that had been previously rewarded. To test whether these jays avoided the location in which their caches had been pilfered or chose the rewarded location, the procedure was repeated to include a 3rd location that was never rewarded. The jays avoided the pilfered location but cached equally in the rewarded and nonrewarded locations.     

Change in affective state assessed by impaired color-naming of threat-related words

This study investigated the effects of mood induction on Stroop color-naming times for threat-related words. The subjects’ task was to color-name sets of threat-related words and affectively neutral matched control words both before and after mood-induction. Subjects were shown a short film about the medical effects of nuclear war (negative affect manipulation), a humorous cartoon, or no film. A significant and highly reliable color-naming decrement of the threat-related words was observed only after the negative affect manipulation. This indicates that the attentional bias towards the processing of threat-related material observed in clinically anxious or high Trait-Anxious subjects can be induced in initially nonanxious subjects. An incidental recall task included in the procedure provided no evidence of mood state dependent recall.     

Musicologia e fenomenologia in F. Joseph Smith

In the last two decades an increasing number of musicians, musicologists and philosophers in the United States of America have dealt with questions of philosophy of music on a phenomenological basis. F. Joseph Smith certainly deserves mention as one of the first and most innovative of these authors. Sections 1 and 2 of the paper sketch a portrait of Smith against the background of the current situation in America, where there is a strong awareness of the need to overcome the present limits imposed by historical musicology in order to develop a new phenomenological approach. Section 3 expounds Smith's critique against traditional theory of musical form and his attempt to redefine musical form on the basis of Husserl's treatise on passive synthesis. This, in the author's opinion, is Smith's most important contribution to a phenomenologically oriented philosophy of music. Finally, section 4 tries to draw some critical conclusions concerning Smith's work, with special regard to the merits and demerits of his idea of phenomenology as applied to music.     

Young People's Perceptions of their Vocational Guidance Needs: Ii. Influences and Interventions

Questionnaire responses from 1,366 pupils at 20 schools in England were used to develop a scale tentatively interpreted as reflecting vocational development. This interpretation was evaluated by concurrent assessments from local careers officers and by its predictive value in the first months on the labour market. Influences on scores included reading ability, social and economic factors, and features of the school. Careers interventions were effective in increasing vocational awareness. Schools providing formal careers education in the fourth or fifth years had pupils whose scores suggested a gain of six months' vocational awareness. The input of the Careers Service was also related to the scale, pupils at schools with more active careers officers appearing more advanced in their vocational development.     

Further validation of a measure of irrational belief

Malouff and Schutte (1986) developed a measure of irrational belief intended to be shorter and more content valid than other such measures and reported preliminary evidence of reliability and validity for the measure. The present two studies examined further the validity of the new measure. Study 1 produced evidence of construct validity in that a significant correlation was found between scores on the Malouff & Schutte measure and scores on a measure of hostility, which is a theoretically related construct. Study 2 produced evidence of construct validity in that scores on the Malouff & Schutte measure were found to be correlated with scores on two measures of theoretically related constructs: anxiety and irrational tendencies/beliefs. Study 2 also produced evidence of discriminant validity in that scores on the Malouff & Schutte measure were found to be significantly more highly correlated with scores on the more theoretically similar irrational tendencies/beliefs scale than with scores on the anxiety measure.     

Do careers officers give good advice?

The National Survey of Health and Development is a longitudinal study of 5,362 young people born in the first week of March 1946 and living throughout Britain. 90% of the 15-year-old school-leavers in the sample were recommended by the Youth Employment Service to take up a particular sort of work. Survey members who followed this advice stayed longer in their first job than young people who took up some other work. Evidence is presented which suggests that this better performance results not from the personality of the young people who accepted advice nor from the superior types of first job they entered, but from the accurate assessment by the careers officer of their abilities and interests.     

SUBJECT TO ROMANCE

Safer sex campaigns directed at heterosexuals have increasingly targeted women to encourage them to take responsibility for condom use. It appears, however, that many women are unable or unwilling to accept this role. In this article we report on one particular kind of obstacle that some women face in initiating condom use. We draw on data from interviews with 14 women, aged 22 to 43 years, about their experiences with, and views of, condoms. There was considerable variability, as well as commonalities, among the women interviewed in the way they regarded condoms. Using a feminist poststructuralist form of discourse analysis, we explored two women's accounts of being unable to initiate condom use despite their stated intentions not to have intercourse without a condom and having condoms in their possession. We suggest that this particular dynamic results from the passivity women can experience through being positioned in a discourse of heterosexual feminine sexuality in general and a discourse of heterosexual romance in particular. We discuss how this passivity can be experienced by women who are otherwise assertive and committed to sexual equality, making it confusing and disconcerting for them and others.
