Predictors of multiple concurrent and multiple sexual partnerships among male and female youth aged 18–24 in South Africa

This study aimed to determine predictors of multiple concurrent and multiple sexual partnerships among South African male and female youth. Data were from a cross-sectional population-based household survey of 3 123 youths aged 18 to 24 years from four South African provinces (males = 53.6%, blacks = 97.8%). Results from a sub-sample of being sexually active in the past 12 months (n = 1787) indicate that 5.3% (7.1% in males and 3.1% in females) youth participants had multiple concurrent sexual partners, and 38.8% (50.1% in males and 25.8% in females) had had two or more sexual partners in the past 12 months. Among females, multiple concurrent partnerships were only predicted by lower social network resources. Predictors of multiple sexual partnerships (two or more sexual partners in the past 12 months) among males included high HIV risk perception, never been tested for HIV and hazardous or harmful alcohol use. By contrast, among females, high peer pressure, lower education and ever having taken drugs predicted involvement with multiple sexual partners. Multi-level health promotion interventions are indicated for sexual behaviour change among South African youth.     

Correlates of illicit drug use among university students in Africa and the Caribbean

The goal of this study was to estimate the prevalence and correlates of illicit drug use (IDU) among university students from eight countries in Africa and three countries in the Caribbean. In a cross-sectional survey, data were collected from 7 017 undergraduate university students (mean age 21.1, SD = 2.7, age range of 18–30 years) from 11 countries. Overall, 17.2% and 3.5% reported infrequent (1–9 times) and frequent (10 or more times) IDU in the past 12 months. In multivariate logistic regression models, residing on or off campus on their own, living in an upper middle or high income country, current tobacco use, binge drinking, and having been in a physical fight in the past 12 months were associated with both frequent and infrequent IDU. In addition, higher intrinsic religiosity and older age was found to be protective from infrequent IDU and associated with never using illicit drugs. The influences on IDU identified may be utilised for the design and implementation of social intervention programmes to curtail IDU by college students.

Luck,envy and gratitude: It could have been different

Previous studies have shown that people feel lucky in situations that could easily have turned into something worse. The present investigation was designed to focus more closely on the comparative aspect of luck, using a linguistic approach (Study 1 and 2) as well as self-reports of perceived luck accompanying selected emotional episodes (Study 3). The participants in Study 1 were asked to comment upon the difference between describing a state of affairs as “lucky” vs. “good”. The term “lucky“ was frequently seen to imply a comparison process, sometimes expressing gratitude (“It is lucky I have a family”) and at other times envy (“it is lucky you have a job”). This was confirmed in Study 2 where statements about self and other being lucky or unlucky were rated for implying comparison, gratitude, envy, concern, and impression of speaker. In Study 3, 60 students described situations in which they had felt grateful towards other people as well as towards “life in general”. Questionnaire answers revealed that they also had felt very lucky and had been thinking “it could have been different”. They also produced recollections of envy, which were rated to imply others' good luck and own bad luck, which could easily have been interchanged (“it could have been merdquo;). It is concluded that counterfactual thoughts are decisive for the experiences of luck, gratitude, and envy.     

Interference in Immediate Spatial Memory: Shifts of Spatial Attention or Central executive Involvement?

Interference in serial spatial memory was investigated in six experiments. Experiment 1 replicated Experiment 2 by Smyth and Scholey (1994) in showing that listening to tones that originated from different directions interfered with spatial memory. Experiment 2 showed, however, that the effect of mere listening was not observed when this was the only interference condition experienced by the subject. In Experiment 3, a binary pitch discrimination task performed on spatially separated tones impaired recall performance to the same extent as did left-right decisions. The same disrupting effect was also observed when the tones were presented from the same direction in the pitch discrimination task (Experiment 4) as well as in a binary loudness discrimination task (Experiment 5). Finally, repeating heard words did not interfere, whereas a pitch discrimination performed on these same words disrupted recall (Experiment 6). It is argued that the disrupting effects reflect not a specifically spatial interference, but a central executive involvement in the rehearsal process in serial spatial memory.     

A Brain of Her Own: A Neural Correlate of Song Assessment in a Female Songbird

The song control region in the avian forebrain is a series of discrete, interconnected nuclei mediating song learning and production. It has been studied in males or in species where both sexes sing. Little is known about the neural correlates of song perception in nonsinging females, often the intended recipients of song. We studied cowbirds (Molothrus ater), a species in which only males sing but in which females discriminate between males on the basis of song. We focused on nucleus lMAN because it has been implicated in early song acquisition, a stage relevant to both sexes to choose among competing acoustic models. We found that volume of lMAN was monomorphic in cowbirds. Moreover, the volume and neuronal number of female lMAN were positively correlated with selectivity of copulatory responding. The results provide strong evidence of nonsinging female's use of “song” control nuclei for song perception without the possibility of song production.     

STROOP INTERFERENCE AND COLOR-WORD SIMILARITY

Abstract— Stroop interference refers to the finding that it takes longer to name the color of an incongruent color (e g, the word blue shown in green) than it does to name the color of a neutral stimulus (e g, a series of number signs shown in green) Incongruent color-word stimuli can differ in the similarity between the color in which the word is printed and the color denoted by the word (e g, the ward blue shown in green vs yellow) This research shows that the amount of interference obtained is related to color-word similarity, suggesting that word-reading and color-naming processes interact at a conceptual level prior to response emission.
