Adaptive modes of rumination: the role of subjective anger.
2015
Rumination has been demonstrated to have negative consequences on affect, behaviour, and physiological markers. Recent studies, however, suggest that distinct "modes" of anger-associated rumination may lead to several positive consequences. Previous research primarily used recall procedures of anger episodes to elicit anger. By contrast, the present study focused on the effect of subjective anger on the process of rumination and tested its effects in a "staged" social interaction where a confederate provoked participants. Subsequently, participants engaged in rumination about the anger-eliciting event either in an abstract-distanced or a concrete-immersed rumination mode. Results showed an …
Sex differences in conditioned stimulus discrimination during context-dependent fear learning and its retrieval in humans: the role of biological sex…
2015
BACKGROUND: Anxiety disorders are more prevalent in women than in men. Despite this sexual dimorphism most experimental studies are conducted in male participants and studies focusing on sex differences are sparse. In addition the role of hormonal contraceptives and menstrual cycle phase in fear conditioning and extinction processes remain largely unknown. METHODS: We investigated sex differences in context-dependent fear acquisition and extinction (day 1) and their retrieval/expression (day 2). Skin conductance responses (SCRs) fear and unconditioned stimulus expectancy ratings were obtained. RESULTS: We included 377 individuals (261 women) in our study. Robust sex differences were observe…
The influence of alcohol on cognitive conflict.
1985
The influence of alcohol on cognitive conflict between individuals was studied by means of an experiment that was designed to be representative of real life negotiating situations, where alcohol is consumed and where two parties are required to find new common solutions to problems that they have previously learned to solve differently by themselves. The subjects were 60 male students of technology divided into experimental and control groups. The amount of alcohol (whisky) consumed by the experimental subjects produced approximately 0.08% blood alcohol concentration. In the experiment, the cognitive conflict situation was created by first training subjects to solve diagnostic medical tasks…
Selecting one of two regular sound sequences : Perceptual and motor effects of tempo
2008
This study assessed the influence of tempo on selecting a sound sequence. In Exp. 1, synchronization with one of the two regular subsequences in a complex sequence was measured. 30 participants indicated a preference for the fastest subsequence when subsequences were in a slow tempo range (≥ 500 msec. IOI), and with the slower subsequence when they were in the fast tempo range (≤ 300 msec. IOI). These results were replicated using a perceptual task (Exp. 2 and 3) in which the 30 listeners had to detect a temporal irregularity in one of the two subsequences. Detection was better when the temporal irregularity was in the fastest subsequence than in the slowest one when the complex sequence w…
Generalization gradients for fear and disgust in human associative learning
2021
AbstractPrevious research indicates that excessive fear is a critical feature in anxiety disorders; however, recent studies suggest that disgust may also contribute to the etiology and maintenance of some anxiety disorders. It remains unclear if differences exist between these two threat-related emotions in conditioning and generalization. Evaluating different patterns of fear and disgust learning would facilitate a deeper understanding of how anxiety disorders develop. In this study, 32 college students completed threat conditioning tasks, including conditioned stimuli paired with frightening or disgusting images. Fear and disgust were divided into two randomly ordered blocks to examine di…
Resilience Patterns
2015
Resilience, or the capacity to be able to develop oneself successfully despite adverse circumstances, has become a concept of interest in recent years. There is a clear relationship between resilience, psychological well-being, and coping strategies. This study looked at 890 subjects with a mean age of 46.77 ( SD = 20.86) years, ranging from 18 and 95 years old. The participants were 40.6% men and 59.4% women. Using this sample, three clusters were developed by MATLAB R2010a and the Self-Organizing Maps toolbox. Two of these had high resilience, and the other one had low resilience; the psychological well-being variables and coping strategies were taken into account. Thereafter, multivaria…
The effects of instrumental reminiscence on resilience and coping in elderly
2014
A B S T R A C T Objectives: Aging, as a stage of development is marked by major changes to which the subject must adapt. Instrumental reminiscence is based on recalling times one coped with stressful circumstances, and analyzing what it took to adapt in those situations. The purpose of the present study was to analyze the effectiveness of an instrumental reminiscent program to enhance adaptive capacity (problemfocused coping and emotion-focused) and resilience in older adults. Method: Thirty participants noninstitutionalized conducted a pre and post assessment on a treatment consisting of the Mini-Mental State Examination (MMSE), Brief Resilient Coping Scale and Stress Coping Questionnaire …
Salivary alpha-amylase response to acute psychosocial stress: The impact of age
2011
a b s t r a c t The impact of stress on health varies across the different stages of human life. Aging is associated with psychobiological changes that could limit our ability to cope with stressors. Therefore, it is crucial to clarify the physiological mechanisms that underlie the stress response and the changes that occur in them as we age. Our aim was to investigate age differences in the salivary alpha amylase (sAA) response to stress, and its relationship with other typical stress biomarkers such as cortisol and heart rate (HR). Sixty-two participants divided into two age groups (younger group: N = 31, age range: 18-35 years; older group: N = 31, age range: 54-71 years) were exposed to…
Life success of males on nonoffender, adolescence-limited, persistent, and adult-onset antisocial pathways: follow-up from age 8 to 42
2009
A random sample of 196 males, drawn from the Jyväskylä Longitudinal Study of Personality and Social Development, was divided into four groups of offenders using information from government registers of convictions between ages 21 and 47, from local police registers searched at age 21, from a Self-Report Delinquency Scale administered at age 36, from a Life History Calendar for ages 15-42, and from personal interviews at ages 27, 36, and 42. The groups were: persistent offenders (offences before and after age 21; 29% of the men); adolescence-limited offenders (offences before age 21; 27%); adult-onset offenders (offences after age 21; 16%); and nonoffenders (28%). The profile of the persiste…
Differential effects of age on subcomponents of response inhibition.
2013
Inhibitory deficits contribute to cognitive decline in the aging brain. Separating subcomponents of response inhibition may help to resolve contradictions in the existing literature. A total of 49 healthy participants underwent functional magnetic resonance imaging (fMRI) while performing a Go/no-go-, a Simon-, and a Stop-signal task. Regression analyses were conducted to identify correlations of age and activation patterns. Imaging results revealed a differential effect of age on subcomponents of response inhibition. In a simple Go/no-go task (no spatial discrimination), aging was associated with increased activation of the core inhibitory network and parietal areas. In the Simon task, whi…
