The transition from high school is a pivotal period for intergenerational relations, as the asymmetry characterizing pre-transition relations with parents is reconfigured. Changes in adolescent–parent relations across this transition have potentially important implications for post-transition adjustment. A prospective study was conducted with an ethnically diverse sample that included adolescents who were not college-bound. Maternal, but not paternal, relations improved across the transition from high school to adult life. Changes in support from both mothers and fathers were associated with changes in relationship satisfaction and changes in satisfaction predicted post-transition adjustment. The results verify the importance of parental support to the quality of relational bonds between young adults and their parents. They also affirm the significance of these bonds for post-transition adjustment.  相似文献

Research shows abnormal function of the pre-frontal cortex in Attention Deficit Hyperactivity Disorder (ADHD). This cortex is involved in the control of executive functions related to planning and execution of goal-oriented strategies, working memory, inhibitions, cognitive flexibility, and selective attention. Selective attention involves focus on the target stimulus, ignoring competing distractions. The Stroop Test (Stroop, 1935) is usually used to evaluate selective attention. This study investigated whether children with ADHD could exhibit modified performance in the Stroop Test. Using a computerized version of this test (Capovilla, Montiel, Macedo, & Charin, 2005), the study compared the reaction times (RTs) of 62 Brazilian children, between 8 and 12 years of age, 31 of whom were diagnosed with ADHD and sent to psychiatric clinics, and 31 without ADHD studying in regular schools. All children with ADHD satisfied the criteria of the DSM-IV-TR and were evaluated with the Conners Abbreviated Questionnaire (Goyette, Conners, & Ulrich, 1978), completed by parents and teachers. The results revealed that children with ADHD exhibit greater interference in RT than children without ADHD. This corroborated the hypothesis that children with ADHD exhibit a deficit in selective attention, consisting in augmented RTs, as measured by the Computerized Stroop Test.  相似文献

A study was carried out with 501 persons to analyze the predictive capacity of various psychosocial variables-symptom perception, neuroticism, Personality Types 2 and 4 of Grossarth-Maticek and Eysenck, beliefs about health, social support, or certain coping styles-on two health-related behaviors: the frequency of visits to the doctor and self-medication. The results were analyzed by two structural equation models that revealed that some of the variables have direct effects on the behaviors, whereas other variables, such as attribution style, coping styles, or the impact of the stressors, have indirect effects via the reported symptoms or neuroticism. In addition, self-medication and the frequency of health service visits are independent of each other, which shows that their determinants are different. It is concluded that to address these factors in the two health indicators, it is also necessary to take in account the psychosocial variables considered herein.  相似文献

Anxiety and cognitive performance: attentional control theory   总被引:1,自引:0,他引:1  
Attentional control theory is an approach to anxiety and cognition representing a major development of Eysenck and Calvo's (1992) processing efficiency theory. It is assumed that anxiety impairs efficient functioning of the goal-directed attentional system and increases the extent to which processing is influenced by the stimulus-driven attentional system. In addition to decreasing attentional control, anxiety increases attention to threat-related stimuli. Adverse effects of anxiety on processing efficiency depend on two central executive functions involving attentional control: inhibition and shifting. However, anxiety may not impair performance effectiveness (quality of performance) when it leads to the use of compensatory strategies (e.g., enhanced effort; increased use of processing resources). Directions for future research are discussed.  相似文献

Coordinated responses of 5 dyads of rats were investigated under fixed-ratio (FR) schedules of mutual water reinforcement. Coordinated responding was defined as 2 consecutive lever-presses, 1 from each of 2 rats, occurring <.5 s apart. In the FR schedules, each coordinated episode was defined as 1 response in the FR sequence. The size of FR schedules was parametrically manipulated assuming the values of FR 1, 6, 12, 18, 24, 30, 50, and 9, in this order. Each FR remained in effect until responding reached stability. Under all conditions, pairs of rats received access to water simultaneously (mutual reinforcement). Rates and proportions of coordinated responding showed a bitonic inverted U-shaped function of ratio size. Postreinforcement pauses increased systematically as the interreinforcement interval increased. Local rates and proportions increased as a function of response location within ratios. Results of a control condition with relaxed temporal constraints for mutual reinforcement showed decreases in rates and proportion of coordinated responses, suggesting that the coordinated responses were controlled by the mutual reinforcement contingencies. The present experiment showed that coordinated responding is quantitatively affected by 3 properties of FR schedules: response requirement, reinforcement rates, and proximity to reinforcement.  相似文献

Our goal was to assess the role of timing in pigeons' performance in the midsession reversal task. In discrete-trial sessions, pigeons learned to discriminate between 2 stimuli, S1 and S2. Choices of S1 were reinforced only in the first half of the session and choices of S2 were reinforced only in the second half. Typically, pigeons choose S2 before the contingency reverses (anticipatory errors) and S1 after (perseverative errors), suggesting that they time the interval from the beginning of the session to the contingency reversal. To test this hypothesis, we exposed pigeons to a midsession reversal task and, depending on the group, either increased or decreased the ITI duration. We then contrasted the pigeons' performance with the predictions of the Learning-to-Time (LeT) model: In both conditions, preference was expected to reverse at the same time as in the previous sessions. When the ITI was doubled, pigeons' preference reversal occurred at half the trial number but at the same time as in the previous sessions. When the ITI was halved, pigeons' preference reversal occurred at a later trial but at an earlier time than in the previous sessions. Hence, pigeons' performance was only partially consistent with the predictions of LeT, suggesting that besides timing, other sources of control, such as the outcome of previous trials, seem to influence choice.  相似文献

Sustainable consumption analyses the choice of products to address environmental issues. In recent years, the circular economy model () has offered strategies as possible solutions to address the growing demand for action on climate justice. The success of a business model depends on understanding the consumer's role. The power of individual consumer actions is vital for minimizing the adverse impacts of climate change. Although the effectiveness of in the business sector has been studied, the literature has ignored the role of consumers in sustainable consumption practices through. Thus, using a survey technique, this quantitative study analyzed part of the theoretical model of Mostaghel and Chirumalla to analyze how awareness and consumer attitude significantly impact purchase intention and ethical purchasing behavior. The data analyzed through PLS-SEM reflected several theoretical implications in the forms of consumer behavior, a topic that has not been addressed in the literature.  相似文献

Abstract

To evaluate whether frequent interactive tablet-use at preschool age is associated with improved fine motor skills and to describe tablet-use in young children. Cross-sectional study with 78 children, aged 24–42?months: group 1 with previous frequent tablet-use exposure (n?=?26), group 2 without previous tablet-use exposure (n?=?52). Fine motor skills were evaluated with the Bayley-III. Socioeconomic data and home environment quality were similar in both groups. Fine motor skills of group 1 were better than those of group 2 (p?=?0.013). Most participating children carried out passive and active tablet activities, usually accompanied by parents, not exceeding time recommendations for young age. We observed a difference in fine motor skills in young children slightly favoring those with tablet-use experience.  相似文献

Efforts to integrate cultural competence and evidence-based treatments (EBTs) typically take the form of cultural adaptations of EBTs, characterized by modifications to the existing treatment based on presumed cultural notions of a given race or ethnic group. Much less attention has been given to ways EBTs can integrate a process model of cultural competence, which focuses on what clinicians do in-session to identify and integrate key cultural factors for a given individual in the treatment. Our objective is to consider how a process model of cultural competence (Shifting Cultural Lenses) can be integrated with an EBT (Behavioral Activation). We present a theoretical rationale for integrating the SCL model with BA and illustrate this integration, which provides an additional approach to bringing culture to treatments and shows promise for identifying clinicians’ in-session behaviors that reflect cultural competence.  相似文献
