Sex differences in genetic and environmental effects on aggression
2003
The aim of the present study was to investigate the genetic and environmental factors influencing teacher and parental rated aggression in boys and girls, asking whether the magnitude of these effects is similar across rater and sex. The study is part of an ongoing nationwide twin-family study of behavioral development and health habits carried out in Finland. The sample consisted of 1651 twin pairs (264 monozygotic male, 300 monozygotic female, 292 dizygotic male, 278 dizygotic female, and 517 dizygotic opposite-sex twin pairs), representing subsets of five 11- to 12-year-old twin cohorts (b. 1983-1987). The data were collected using the teacher and parental rating forms of the Multidimens…
Effects of acute administration of nicotine and lobeline on agonistic encounters in male mice
2000
The effects of acute administration of two nicotinic ligands, (-)-nicotine and (-)-lobeline were examined on isolation-induced aggression in mice. Individually housed male mice confronted anosmic “standard opponents” in a neutral arena 10 min after drug administration. Encounters were videotaped and evaluated using an ethologically based analysis facilitating estimation of time allocated to 11 broad behavioral categories. Nicotine did not have significant effects on threat or attack but significantly diminished time allocated to digging. The lowest dose of lobeline significantly diminished attack and induced a slight increase of immobility without significantly diminishing other behaviors w…
A Cross-Cultural Study in Spain and Mexico on School Aggression in Adolescence
2016
The purpose of the present study was to examine the relationships between family and classroom environments and the development of particular individual characteristics, including level of empathy, attitude to institutional authority, and perceived social reputation, and the role these characteristics may in turn play in aggressive behavior. These factors and associations were analyzed by gender and in two different Latin contexts, Spain and Mexico, from a cross-cultural perspective. Participants in the study were 1,319 Spanish adolescents and 1,494 Mexican adolescents drawn from secondary schools. Structural equation models were calculated to test mediational effects among variables. Resu…
THE EFFECT OF SPACED VS. MASSED PRESENTATION OF AGGRESSION ITEMS ON VERBAL AGGRESSIVE RESPONSES OF CHILDREN
1963
A story completion test was constructed and administered to 99 ten-year-old boys. The main results were: (1) The average number of aggressive responses tends to be lower when the aggression items are presented in a ‘spaced’ manner than when they are ‘massed’. (2) There is a spread effect from aggression items to neutral items. Aggression and neutral items presented in mixed order give a stronger effect. (3) A relatively consistent factor structure of aggression responses was shown in the test. Aggression towards peers and authority were independent of each other, and seem to be influenced differently by the manner of presentation of stimuli.
Offensive and defensive aggression in humans: A longitudinal perspective
1987
Offensive and defensive aggression were distinguished on the basis of associated events. Behavior delivering noxious stimuli was defined as defensive when it was a response a threatening situation and as offensive when it was an unprovoked act. The existence of a general aggression factor was implied by the finding that initiators of aggression also readily defend themselves if attacked. The use of a peer nomination and teacher rating variable for offensive aggression, “Attacks without reason, teases others, naughty things”; and another for defensive aggression, “Defends him/herself if teased, but does not tease or attack others without reason,” yielded differential results. Offensive aggre…
An aggression machine v. determinants in reactive aggression revisited
2001
The relations between reactive aggression, situational cues, and emotion regulation were examined by means of the Pulkkinen Aggression Machine (PAM) task. In the PAM, provocation and response were systematically varied under two conditions: the impulsive aggression condition and the controlled aggression condition. In the impulsive condition, no information about the attacker was provided, while in the controlled condition the attackers were specified in terms of sex, age, and physical strength. The task was administered to 109 children aged 8 to 13 years. Boys (n = 61) and girls (n = 48), as well as subgroups of Adjusted (n = 67) and Maladjusted (n = 26) children were compared. The results…
Media portrayals of transitions from work to retirement in two ageing societies : the case of ageing baby boomers in Japan and Finland
2021
This article explores media portrayals of the transition from work to retirement under the circumstances of demographic change through a focus on newspaper discussions about ageing baby boomers in Japan and Finland. Due to their shared characteristics as a distinct population group that advances the rapid ageing of the population, media representations of Japanese and Finnish baby boomers during the transitional period to retirement give insight into the social perceptions of retirement and their implications on later life. Manifest content analysis and subsequent thematic analysis identify that the topic of “work, retirement and pension” dominates media discussions in both countries. Analy…
“I do those things to pass the time.”: Active ageing during fourth age
2021
Active ageing is a dominant but disputed discourse in the field of ageing. Since it is usually associated with the third age, this article will focus on the active ageing of older adults who need care and services, who are known as the fourth agers. Our data consists of interviews collected from 16 older adults. We analysed the data through content analysis that was guided by the Active Ageing Index (AAI) that is a measuring tool concerning active ageing. According to our results, active ageing during the fourth age can be understood through the lens of small actions and precarity. Although some actions had to be given up or modified, participants were active in various ways, and help from …
Personality profiles and health: Longitudinal evidence among Finnish adults
2012
Kinnunen, M.-L., Metsapelto, R. L., Feldt, T., Kokko, K., Tolvanen, A., Kinnunen, U., Leppanen, E. & Pulkkinen, L. (2012). Personality profiles and health: Longitudinal evidence among Finnish adults. Scandinavian Journal of Psychology 53, 512–522. This study investigates the associations of longitudinal Big Five personality profiles with long-term health in 304 adults (53% males). Personality traits (Neuroticism, Extraversion, Openness, Conscientiousness, Agreeableness) were assessed at ages 33, 42, and 50. Subjective (self-rated health, symptoms, psychological distress) and objective (body mass index, waist-to-hip ratio, blood pressure, cholesterol, triglycerides) indicators of health were…
The relationship between the FFM and personality disorders in a personnel selection sample
2012
Nederstrom, M. & Furnham A. (2012). The relationship between the FFM and personality disorders in a personnel selection sample. Scandinavian Journal of Psychology 53, 421–429. The relationships between the Five Factor Model (FFM) personality and personality disorders were investigated. A sample of real-life job applicants completed two personality questionnaires with different theoretical backgrounds in a psychological assessment center. The job applicants provided self-descriptions both on the FFM inventory and on a personality disorder trait inventory. A subsample of these candidates was interviewed by expert psychologists upon entrance to the assessment center. The psychologists assessed…
