This paper presents the theoretical and methodological basis of a therapist's verbal behavior category system that allows us to study clinical psychologists' language from a functional-analytic framework and with a rigorous observation method. The procedure to develop the coding system is explained in detail from a very early stage of exploratory observation, to the systematic observation through the use of The Observer XT software. An analysis of intra- and inter-rater reliability using the kappa coefficient and taking into account the factors that affect the values of Cohen's index was carried out. Results show high levels of observer accuracy (between approximately 87% and 93%) that justify the application of this category system to study therapists' verbal behavior in session.  相似文献

The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequency could not be detected in motor learning, 67% of the feedback was recommended for motor adaptation.  相似文献

The present study aimed to verify the association between maternal depression and emotional and behavioral problems in school children in Pelotas, Southern Brazil, considering that maternal depression increases children’s vulnerability for developing psychiatric disorders. This is a cross-sectional study with a school-based sample conducted between August 2015 and November 2016 and it is part of a major project entitled ‘Healthy Childhood in Context: A Multidisciplinary Investigation’. Schoolchildren aged between 7 and 8 years and one of their respective parents or a primary caregiver were included in the study. Maternal depression was assessed using the Mini International Neuropsychiatric Interview (MINI). The presence of emotional and behavioral problems in children was verified by the Strengths and Difficulties Questionnaire (SDQ) – parents version. Children of depressed mothers exhibited higher mean scores in all SDQ domains and in the total score when compared to children of non-depressed mothers. Lower socio-economic status was also associated with higher SDQ scores. Our results showed the effects of both maternal depression and poverty on children emotional and behavioral problems, which evidence the need for child mental health preventive care, and free quality assistance for both mothers and their children.  相似文献

Gender is recognized as an important social determinant of health, but past research on gender differences in psychological well-being have not produced conclusive results. This study investigated gender differences in eudaimonic well-being and life satisfaction in emerging adulthood. A cross-sectional study with a sample of 1990 emerging adults (50% males) from the Spanish general population was conducted. Participants were assessed through five questionnaires. Results showed that women scored higher than men in purpose in life and personal growth. Hierarchical multiple regression analysis revealed that the most important predictors of emerging adult men’s and women’s eudaimonic well-being and life satisfaction were higher self-confidence and lower negative self-evaluation. Other significant variables in the eudaimonic well-being of both women and men were higher score in the masculine/instrumental trait, higher emotional social support, higher educational level, and higher score in the feminine/expressive trait. Furthermore, higher instrumental social support was associated with eudaimonic well-being in females. Other predictors of women’s and men’s life satisfaction were higher score in the feminine/expressive trait, less age, higher educational level and higher instrumental social support. In addition, higher emotional social support was associated with life satisfaction in males. The results suggest that gender is important in the psychological well-being of people in emerging adulthood, although self-esteem and instrumental social support are, in both emerging adult women and men, the most important predictors of psychological well-being.

Recent studies demonstrated important differences between short- and long-term memory mechanisms. Besides, the emotional component has a crucial role in memory formation. This study was carried out to answer whether there is a differential influence of emotional arousal in short- and long-term memory in healthy adults. Thirty-one healthy volunteers were divided into two major groups. In the first group long-term memory (LTM) was evaluated, with the testing session one week after training. The second group was tested 1h after training, where short-term memory (STM) was evaluated. Each group was divided in to two subgroups. One half of the volunteers was exposed to an emotionally neutral story, and the other half of each group was exposed to a closely matched but more emotionally arousing story. The testing session consisted of a questionary containing 80 questions of multiple choices. The results were evaluated through percentage of correct answers. Results showed that correct answers were increased, in LTM measures, in the subjects that were given the emotional version of the test. In STM measures, no differences were found between the emotional and neutral version. However, the presentation of emotional story caused an emotional reaction in both groups. The lack of effect of emotional arousal in STM suggests that amygdala is not related to STM mechanisms. Further studies using different approaches are needed to elucidate if STM processes are influenced by emotional arousal.  相似文献

Subjects were presented with briefly exposed visual displays of words that were common first names with a length of four to six letters. In the main experiment, each display consisted of four words: two names shown in red and two shown in white. The subject’s task was to report the red names (targets), but ignore the white ones (distractors). On some trials the subject’s own name appeared as a display item (target or distractor). Presentation of the subject’s name as a distractor caused no more interference with report of targets than did presentation of other names as distractors. Apparently, visual attention was not automatically attracted by the subject’s own name.  相似文献
