Stability of aggression among adolescents over time: A south African study

In a study spanning 5 years, data were collected on the aggressiveness of over 1,700 male and female subjects. Subjects who were the more aggressive grade 8 (standard 6) pupils at the beginning of the study were discovered to be the more aggressive grade 12 (standard 10) pupils. It is concluded that, whatever its causes, aggression can be viewed as a persistent trait that may be influenced by situational variables but reveals substantial consistency over time. The findings of studies by Huesmann and Eron in the United States as well as Olweus in Scandinavia were thus supported in this South African investigation.     

A national survey of older smokers: treatment needs of a growing population

Examined smoking and quitting patterns among 289 smokers ages 50 to 74 years who took part in a nationwide survey of American Association of Retired Persons members. Respondents were predominantly chronic, heavy smokers. They had smoked for an average of 45 years, more than one third smoked 25 or more cigarettes per day, and more than two thirds showed evidence of high nicotine addiction. Nonetheless, most were interested in quitting smoking and reported plans to quit in the next year. Concerns about missing or craving cigarettes; losing a pleasure; and being nervous, tense, or irritable after quitting were the most common barriers to quitting reported. These problems were rated as more serious by heavier, longer term smokers and by smokers with lower quitting self-efficacy. The variables most strongly associated with "contemplating" quitting were beliefs in quitting health benefits, recent attempts to quit or cut down, prior attempts to quit, and high self-efficacy. Limitations of these findings are discussed along with implications for the design of treatments geared to the special needs of older smokers.     

Life before and after quitting smoking: an electronic diary study

This article describes a multidimensional, multivariate, and multilevel approach to the assessment of nicotine withdrawal. In this prospective study, 70 adult smokers assigned to an active or placebo nicotine patch condition completed multiple daily assessments using an electronic diary. Average and individual growth curves were estimated for affective and nonaffective withdrawal symptoms. All symptoms but hunger increased significantly on the quit day and remained elevated for three weeks. Variability in symptom experiences across individuals increased from pre- to post-quit. Relations between symptom reports (e.g., negative affect or craving) and episodic events (e.g., stressful events or seeing someone smoke) changed from pre-quit to post-quit. Pre-quit increases in negative affect and quit-day increases in craving were inversely related to abstinence three months after the quit day, suggesting that anticipatory and immediate reactions to quitting influence success.     

Noise and visual choice-reaction time: A large-scale population survey

The impact of a 80 dB(A) intermittent broadband noise on a three-choice visual reaction time (RT) task was investigated. There were 2661 subjects who represented the healthy Finnish population from the age of 30 to 79 years. Noise slowed down the response speed highly significantly but the main effect was negligible in the psychological sense (513 vs. 506 msec). The performance of the elderly was more affected than that of the young. Slow responders did not show any detrimental effect of noise irrespective of whether or not they committed errors. The results are discussed in terms of person-induced ways to perform and cope under a mild stress.     

Changes in masculine and feminine traits over time: A meta-analysis

Sixty-three samples providing single-sex means on the Bem Sex-Role Inventory [BSRI; S. L. Bem (1974) “The Measurement of Psychological Androgyny,”Journal of Consulting and Clinical Psychology, Vol. 42, pp. 155–162] and 40 reporting similar data on the Personal Attributes Questionnaire [PAQ; J. T. Spence and R. L. Helmreich (1978)Masculinity and Feminity, Austin University of Texas Press] for American undergraduates were located and analyzed. Women’s scores on the BSRI-M and PAQ-M (masculine) scales have increased steadily over time (r’s = .74 and .43, respectively). Women’s BSRI-F and PAQ-F (feminine) scale scores do not correlate with year. Men’s BSRI-M scores show a weaker positive relationship with year of administration (r = .47). The effect size for sex differences on the BSRI-M has also changed over time, showing a significant decrease over the twenty-year period. The results suggest that cultural change and environment may affect individual personalities; these changes in BSRI and PAQ means demonstrate women’s increased endorsement of masculine-stereotyped traits and men’s continued nonendorsement of feminine-steretyped traits. A version of this paper was presented at the 1995 annual meeting of the American Psychological Association, August 11–15, New York. I. would like to thank Abigail J. Stewart and Randy J. Larsen for their helpful comments on earlier versions of this paper.     

Job experiences over time, multiple roles, and women's mental health: a longitudinal study.

Are changes over time in the quality of a woman's job associated with changes in her psychological distress? Do family roles moderate these relationships? We addressed these questions using longitudinal data from a 2-year 3-wave study of a stratified random sample of 403 employed women who varied in occupation, race, partnership, and parental status. After estimating individual rates of change for each woman on each of the predictors and the outcome, we modeled the relationships between family role occupancy and change in job-role quality on the one hand, and change in psychological distress on the other. Among single women and women without children, as job-role quality declined, levels of psychological distress increased. Among partnered women and women with children, change in job-role quality was unrelated to change in psychological distress.     

Reaction time and intelligence: A replicated study

Two samples of adult subjects of reasonably average intelligence were given IQ tests and a series of RT tests using 0, 1, 2, and 3 bits of information in a Hick paradigm. Both series showed negative correlation between IQ on the one hand, and RT and σRT, on the other, confirming earlier work. On the other hand, there was no evidence of correlation between the Hick slope and IQ, and the correlation between IQ and RT of σRT did not increase from 1 to 3 bits of information. It was found that the Hick paradigm did not apply to some 20% of the samples, and that the exclusion of these nonconformists increased the correlation between IQ and RT/σRT.     

Personality over time: Methodological approaches to the study of short-term and long-term development and change

Although theories of personality emphasize the integrative, enduring, and dynamic nature of personality, the current modal research design in personality ignores the dimension of time. We consider a variety of recent methods of longitudinal data analysis to examine both short-term and long-term development and change in personality, including mean-level analyses both across and within individuals across time, variance structures across time, and cycles and dynamic models across time. These different longitudinal analyses can address classic as well as new questions in the study of personality and its development. We discuss the linkages among different longitudinal analyses, measurement issues in temporal data, the spacing of assessments, and the levels of generalization and potential insights afforded by different longitudinal analyses.     

Inspection time and everyday functioning: A longitudinal study

We tested whether level and/or changes in inspection time (IT) in an elderly sample (70–85 years at baseline) predicted future independence in everyday functioning, independent from chronological age. Sixty-eight participants were initially assessed on IT and cognitive abilities in 2003, reassessed on IT in 2005, and then completed the Everyday Problems Test, a test of independence in everyday living, in 2008. Controlling for age, lower fluid reasoning at baseline (Raven’s-subset) and slowing IT over 18 months independently predicted poorer everyday functioning in 2008, together accounting for one-third variance. This supports the proposition that IT has utility as a biomarker for less favourable ageing.     

Intelligence and religiosity: Within families and over time

We study the effect of intelligence (General Mental Ability) on religiosity using research designs that allow for stronger causal inferences compared to previous research in this area. First, we examine how between-siblings differences in intelligence are related to differences in their religiosity. Second, we examine how intelligence is related to changes in religiosity over time. The results of both designs suggest that intelligence has a strong negative effect on religiosity. In addition, our results also suggest that intelligence interacts with age in determining religiosity: the more intelligent the person, the stronger the negative effect of age on religiosity.     

Perceived influence in groups over time: How associations with personality and cognitive ability can change over time

The ability of personality and cognitive ability to predict perceptions of group influence in small work groups are assessed both in initial and advanced stages of group formation. Extraversion is found important to initial perceptions of intra-group influence, which is partially mediated by peer-perceived social-emotional usefulness. After a few months, reputations are established and everyone has met; now work needs to get done efficiently and accurately and cognitive ability predicts increases in perceived group influence, which is partially mediated by perceived intelligence. After even more time, other Big Five personality traits become important to changes in perceived group influence, with positive associations with openness to experience, and negative associations with neuroticism and conscientiousness. The study findings and implications are discussed.     

Relationships between parenting and adolescent adjustment over time: genetic and environmental contributions.

The predictive association between parenting and adolescent adjustment has been assumed to be environmental; however, genetic and environmental contributions have not been examined. This article represents one effort to examine these associations in which a genetically informative design was used. Participants were 395 families with adolescent siblings who participated in the Nonshared Environment in Adolescent Development (D. Reiss et al., 1994) project at 2 times of assessment, 3 years apart. There were 5 sibling types in 2 types of families: 63 identical twins, 75 fraternal twins, and 58 full siblings in nondivorced families and 95 full, 60 half, and 44 genetically unrelated siblings in stepfamilies. Results indicate that the cross-lagged associations between parental conflict-negativity and adolescent antisocial behavior and depressive symptoms can be explained primarily by genetic factors. These findings emphasize the need to recognize and examine the impact that adolescents have on parenting and the contribution of genetic factors to developmental change.     

Causal structure learning over time: observations and interventions

Seven studies examined how people learn causal relationships in scenarios when the variables are temporally dependent - the states of variables are stable over time. When people intervene on X, and Y subsequently changes state compared to before the intervention, people infer that X influences Y. This strategy allows people to learn causal structures quickly and reliably when variables are temporally stable (Experiments 1 and 2). People use this strategy even when the cover story suggests that the trials are independent (Experiment 3). When observing variables over time, people believe that when a cause changes state, its effects likely change state, but an effect may change state due to an exogenous influence in which case its observed cause may not change state at the same time. People used this strategy to learn the direction of causal relations and a wide variety of causal structures (Experiments 4-6). Finally, considering exogenous influences responsible for the observed changes facilitates learning causal directionality (Experiment 7). Temporal reasoning may be the norm rather than the exception for causal learning and may reflect the way most events are experienced naturalistically.     

The long-term retention of time: A developmental study

Two experiments investigated the age-related changes in long-term retention of duration and their effects on time judgement. Children aged 3, 5, and 8 years old were given a temporal bisection task with or without a 15-min interfering task (Experiment 1), or a retention delay lasting for 0 min, 15 min, or 24 hr (Experiment 2) between the presentation of the standard durations and the comparison stimulus durations. An interfering task and the increase of the retention delay significantly decreased the time sensitivity in the 3- and the 5-year-olds, and to a greater extent in the younger children, but had no effect in the 8-year-olds. This decrease in time sensitivity with the interfering task or the retention delay might be due to an increase in the variability of the remembered duration.     

Odor recognition and identification: effect of labels over time

The effect of labels on recognition and identification of odors over time was assessed. 30 men and 30 women were presented 20 odors; half of the participants were also told a name for the odor as a label. Five min. and 60 min. later, all participants were given 20 odors (10 from the original set, 10 new) and asked whether each odor was new or old (odor recognition). The group given labels was also asked to recall the label provided (odor identification). Analysis indicated a significant effect of time on recognition. Significantly more odors were recognized at 5 min. than 60 min. The effect of label was also significant, with recognition being better for the Label condition than the No-Label condition. As for odor identification, women identified more labels than did men. Overall, odor recognition was better with labels soon after exposure, and the women were better at remembering the labels than the men.     

Women in popular music: A quantitative analysis of feminine images over time

Popular song lyrics from the years 1946, 1956, 1966, and 1976, were content analyzed for feminine images. Eleven stereotyped female images were examined: woman as evil; emphasis on physical characteristics; woman's need for man; woman as a possession of man; woman as mother; woman as sex object; woman as delicate; woman as child; woman on a pedestal; woman as physically attractive; and woman as supernatural. Significant changes over time were found for 8 of the 11 images. Of the songs sampled from 1946–1976, 96% contained at least one of the female stereotypes examined in this investigation.     

An epistemological history of time: From technology to representations

Abstract

This paper attempts to link the social history of the mechanization of time with the history of the psychological notion of time. Historical processes such as the mechanization of tower clocks from the Middle Ages onwards, the reform of the Gregorian calendar and the quarrel of the Christian and Chinese calendars characterized the modern representation of time on three points: isochrony, desacralization and abstraction. While Western societies learned to domesticate the practical aspects of time, the scholars of the Enlightenment naturalized time. They considered it a concept only related to man and used quantified time for scientific purposes. Empiricists saw time as a product of the succession of thought while idealists considered it a form necessary for the human experience to occur. Both trends agreed in removing time from nature and accepted isochrony, desaralization and abstraction as the necessary foundation for the modern notion of time.
