Bērna agresīvas uzvedības novēršanas iespējas vidējā pirmsskolas vecumā

2022

Darba autors: Gita Arbuzova Darba tēma: Bērna agresīvas uzvedības novēršanas iespējas vidējā pirmsskolas vecumā. Darba rezultāti: Katram bērna vecumposmam ir savas attīstības īpatnības, kas ietekmē bērna reakciju uz ārēju vai iekšēju kairinājumu. Bērns uzkrātās emocijas vēl tikai mācās izpaust, tāpēc pedagogiem un bērnu vecākiem ir jābūt kompetentiem par bērnu vecumposmu attīstības īpatnībām, lai veiksmīgāk varētu pielietot dažādas korekcijas metodes, kas mazinātu bērnu agresīvu uzvedību pirmsskolā. Tāpat ir svarīgi saprast, kādas uzvedības funkcijas atbilst konkrētajai situācijai, un jāveic padziļināta izpēte, lai saprastu, kādās situācijās izpaužas agresīva rīcība. Varbūt tie ir diennakts…

Sexism and Aggression in Adolescence.¿How Do They Relate to Perceived Academic Achievement?

2018

Sexist attitudes are rooted in patriarchal structures, which uphold traditional gender stereotypes, and which are still found in society today. Scholars have found gender differences in perceived academic achievement, with girls performing better than boys, and negative relationships between sexism and perceived academic achievement. Moreover, perceived academic achievement and sexist attitudes have been associated with aggression and different kinds of violence. This study examined the associations between sexist attitudes and perceived academic achievement (using self-report data). The study also assessed the mediating role of physical and verbal aggression in the relationship between sex…

Plumage colour and male-male interactions in the pied flycatcher

1993

Abstract Abstract. The influence of male colour on male-male interactions in the pied flycatcher, Ficedula hypoleuca , was studied using several types of field experiments. This species exhibits delayed plumage maturation, each male becoming more conspicuously black and white from the first to the second breeding summer. However, individual males vary even more, some old males being as brown as females. When territorial males were presented with a choice between brown and black male intruders (or brown males painted black) they directed more aggression towards the black males. Brown plumage did not help males obtain nestboxes close to other males. If anything browner males were at a disadva…

Factors Affecting Interspecific Aggression in a Year-Round Territorial Species, the Jewel Damselfish

2012

Vertebrates live in complex species networks in which interspecific interactions are common. In some contexts, the aggressive behaviours shown in these interspecific interactions are very similar to those shown in intraspecific interactions. It is still an open question whether intra- and interspecific aggression share common causality. We studied a year-round territorial species the jewel damselfish, (Plectroglyphidodon lacrymatus), which cultivate algae they feed on. Territory holders aggressively defend these algae that are an attractive resource for many other species. In this study, we recorded territorial aggression in free-living individuals and recorded aggressive responses to a sta…

Parasite-induced aggression and impaired contest ability in a fish host

2010

Abstract Background Success of trophically transmitted parasites depends to a great extent on their ability to manipulate their intermediate hosts in a way that makes them easier prey for target hosts. Parasite-induced behavioural changes are the most spectacular and diverse examples of manipulation. Most of the studies have been focused on individual behaviour of hosts including fish. We suggest that agonistic interactions and territoriality in fish hosts may affect their vulnerability to predators and thus the transmission efficiency of trophically transmitted parasites. The parasite Diplostomum spathaceum (Trematoda) and juvenile rainbow trout, Oncorhynchus mykiss, were used to study whe…

Female-female aggression and female mate choice on black grouse leks.

2000

We studied female-female aggression in relation to female mate choice in black grouse, Tetrao tetrix, in central Finland, in 1994-1998. Aggression occurred on average every other minute when there was more than one female on a territory, and aggressive behaviour was most prominent when several females attended the lek. Interactions tended to be proportionally most frequent on the territories of the highest-ranking males, although not significantly so. Females that were chased by other females did not mate with lower-ranking males than their aggressors did. Furthermore, chased females were only rarely (6% of cases) forced to move off the territory by agonistic interactions and copulations we…

Age and ovarian development are related to worker personality and task allocation in the ant Leptothorax acervorum

2014

Abstract In social insects, workers of different morphological castes and age are known to act differently. Yet, it is unclear how body size and ovarian development influence worker personalities (i.e. consistent behavioral variation) and task allocation in similar aged ant workers of monomorphic species. Behavioral variation is thought to be a key element of division of labor, but few studies have linked worker personality to task allocation. We investigated individual behavior in Leptothorax acervorum ant workers at two time points during the first three months of their life and in two different settings. We observed worker behavior in the nest (i.e. task allocation) and in standardized a…

Self-regulation, especially the regulation of emotion, is an important component of athletic performance. In our study, we tested the effect of a self-distancing strategy on athletes’ performance in an aggression-inducing experimental task in the laboratory. To this end, we modified an established paradigm of interpersonal provocation [Taylor Aggression Paradigm (TAP)], which has the potential to complement field studies in order to increase our understanding of effective emotion regulation of athletes in critical situations in competitions. In our experimental setting, we first tested the applicability of the self-distancing perspective and the athletes’ ability to dynamically adapt beside…

Female Attraction Behaviour of Radio Tagged Polyterritorial Pied Flycatcher Males

1993

AbstractPolygynous mating is costly for pied flycatcher (Ficedula hypoleuca) females. Thus, females have a good reason to attempt to avoid mating with already mated polyterritorial males. One cue to disclose a male's mating status is his behaviour. The behaviour of polyterritorial and unmated males was studied by radio tagging that allows accurate recording of male movements. While attracting a secondary female polyterritorial males spent significantly less time on the secondary territory than did unmated males on their single territory. Polyterritorial males also tended to have lower song rates. When a female appeared on the secondary territory of polyterritorial males, they increased the …
