What do pre-adolescents and adolescents understand about HIV/AIDS?

Abstract

Pre-adolescents and adolescents (N= 80, aged 10, 12, 15, and 18 years) were tested on their knowledge of HIV/AIDS. Knowledge was assessed using a self-report questionnaire (examining levels of factual knowledge) and a semi-structured interview (examining cognitive developmental levels of understanding). Examination of the developmental shifts in understanding of HIV/AIDS revealed an increase in conceptual complexity on causal and prevention dimensions. The main conceptual changes included a shift from single cause to multiple cause solutions and a shift from identifying surface or immediate features to implicating less salient features. Additionally, with age, concepts about HIV/AIDS were increasingly organised around internal, physiological principles. Questionnaire responses yielded significant age-related increases in knowledge. Level of knowledge, as measured by the questionnaire, was higher than that assessed by the interview for the three youngest age groups. Thus, factual information acquired about HIV/AIDS is not automatically accompanied by understanding. In light of these findings the past conclusion that adolescents have high levels of knowledge of HIV/AIDS is questioned.     

Why do individuals respond to fraudulent scam communications and lose money? The psychological determinants of scam compliance

Why do so many people all over the world, so often, react to completely worthless scam offers? In two questionnaire studies, one of which included the distribution of an experimentally manipulated simulated scam, we investigated differences between respondents who did and did not report past compliance with scams. We found that the principal differences were in their response to very high‐value incentives, in the extent to which they reacted with positive emotions to the thought of winning a large prize, in their reliance on signs of official authority, and in their self‐confidence. The first two of these can be regarded as forms of visceral processing. Some of these differences suggested a dispositional difference between victims and non‐victims.     

Rumination and Impaired Cortisol Recovery Following a Social Stressor in Adolescent Depression

Response styles theory promotes rumination as a central cognitive construct driving negative mood and depression, and past research suggests that at least part of the mechanism driving rumination’s depressogenic effect is through inhibiting the individual’s ability to shift attentional focus away from negative environmental stimuli. In the current study, we hypothesized that high trait rumination would be associated with impaired recovery of the body’s biological response to psychological stress. In a community sample of depressed (n?=?31) and non-depressed (n?=?33) adolescents we assessed rumination and the more adaptive trait of distraction and problem-solving with the Children’s Response Styles Questionnaire (CRSQ; Abela 2000), and diagnostic status was confirmed using the Child and Adolescent Schedule of Affective Disorders and Schizophrenia (K-SADS; Kaufman et al. Journal of the American Academy of Child and Adolescent Psychiatry 36:980–988, 1997). Participants completed the Trier Social Stress Test (TSST; Kirschbaum et al. Neuropsychobiology 28:76–81, 1993), and the focus of our analyses was the change in salivary cortisol concentration between peak cortisol output (25 min post-stressor) and a sample taken during the “Recovery” period 65 minutes post-stressor. Consistent with the predictions of response style theory, among the depressed adolescents only, high trait rumination was associated with delayed post-stressor cortisol recovery, whereas high trait distraction and problem-solving was associated with more rapid recovery. In contrast, response styles were not associated with cortisol recovery in the non-depressed group. These findings implicate impaired post-stress cortisol recovery as a potential mechanism underlying the pathological effect of rumination on the development and maintenance of Major Depressive Disorder (MDD).     

Psychometric properties of the Behavioral Inhibition Questionnaire in preschool children

We examined the psychometric properties of the Behavioral Inhibition Questionnaire (BIQ; Bishop, Spence, & McDonald, 2003), a rating scale for children's behavioral inhibition. Parent and teacher ratings, parent interviews, and laboratory observations were obtained for 495 preschoolers. Confirmatory factor analysis yielded 6 factors, each reflecting the BIQ's subscales, and all loading onto a second-order general dimension. Model fit was acceptable for parent ratings, but only marginal for teacher ratings. The convergent and discriminant validity of the BIQ was examined by using a multitrait-multimethod approach. Results indicate that the BIQ displays evidence of reliability and validity that can complement observational paradigms.     

Trouble articulating the right words: Evidence for a response‐exclusion account of distraction during semantic fluency

It is widely held that single‐word lexical access is a competitive process, a view based largely on the observation that naming a picture is slowed in the presence of a distractor‐word. However, problematic for this view is that a low‐frequency distractor‐word slows the naming of a picture more than does a high‐frequency word. This supports an alternative, response‐exclusion, account in which a distractor‐word interferes because it must be excluded from an articulatory output buffer before the right word can be articulated (the picture name): A high, compared to low, frequency word accesses the buffer more quickly and, as such, can also be excluded more quickly. Here we studied the respective roles of competition and response‐exclusion for the first time in the context of semantic verbal fluency, a setting requiring the accessing of, and production of, multiple words from long‐term memory in response to a single semantic cue. We show that disruption to semantic fluency by a sequence of to‐be‐ignored spoken distractors is also greater when those distractors are low in frequency, thereby extending the explanatory compass of the response‐exclusion account to a multiple‐word production setting and casting further doubt on the lexical‐selection‐by‐competition view. The results can be understood as reflecting the contribution of speech output processes to semantic fluency.     

Correspondence of children's anticipated vocations, perceived competencies, and interests: Results from an Italian sample

Relations among anticipated vocations, self-assessments of competence, and interests in sample of 190 Italian children were examined. Children were asked what activities they liked, those they thought they were good at, and what job they expected when they grew up. The responses were coded into RIASEC Holland codes and agreement across the three questions was examined using kappa statistics. Results indicated that there was no relation between anticipated occupations and either interest or perceived competence. Thus, these anticipated occupations appear to be based on unrealistic criteria and the validity of studying such early expressions of interest is questionable. Conversely, results demonstrated a correspondence between interest and competence and this correspondence was similar for boys and girls and increased with age.     

Sweet silent thought: alliteration and resonance in poetry comprehension

ABSTRACT— Poetic devices like alliteration can heighten readers' aesthetic experiences and enhance poets' recall of their epic pieces. The effects of such devices on memory for and appreciation of poetry are well known; however, the mechanisms underlying these effects are not yet understood. We used current theories of language comprehension as a framework for understanding how alliteration affects comprehension processes. Across three experiments, alliterative cues reactivated readers' memories for previous information when it was phonologically similar to the cue. These effects were obtained when participants read aloud and when they read silently, and with poetry and prose. The results support everyday intuitions about the effects of poetry and aesthetics, and explain the nature of such effects. These findings extend the scope of general memory models by indicating their capacity to explain the influence of nonsemantic discourse features.     

Work-family conflict and psychological well-being: Stability and cross-lagged relations within one- and six-year follow-ups

The rank-order stability and cross-lagged relations between work-to-family conflict (WFC), family-to-work conflict (FWC), and psychological well-being were examined in two longitudinal studies with full two-wave panel designs. In Study 1 (n = 365), the time lag was one year, and in Study 2 (n = 153), six years. The Structural Equation Modeling showed that the stability for WFC was .69 over one and .73 over six years. The respective stabilities for FWC were .57 and .48. Cross-lagged relations were not detected between WFC/FWC and low psychological well-being (job exhaustion, marital adjustment, parental stress, and psychological distress), expected to exist on the basis of the integrative model of work-family interface [Frone, M. R., Yardley, J. K., & Markel, K. S. (1997). Developing and testing an integrative model of the work-family interface. Journal of Vocational Behavior, 50, 145-167.]. Instead, high job exhaustion preceded high psychological distress, both within one- and six-year time lags, and within a one-year time lag: low marital adjustment preceded high psychological distress, and high psychological distress preceded high parental stress. These findings supported the spillover perspective on work-family interface [Edwards, J. R., & Rothbard, N. P. (2000). Mechanisms linking work and family: Clarifying the relationship between work and family constructs. Academy of Management Review, 25, 178-199.].
