The purpose of this phenomenological investigation was to explore experiences of altruism in the therapeutic relationship to better understand how counselors‐in‐training (CITs) and their clients mutually perceived the construct in sessions. Findings from interviews with clients (n = 14) included emotional–relational characteristics and cognitive–behavioral aspects of altruism by their counselors. Findings from interviews with CITs (n = 10) included explorations of the role of altruism in counseling, overall experiences of altruism in counseling sessions, and experiences of altruism with specific clients. Implications for practice and research are discussed.  相似文献

Evidence suggests that anxiety is associated with a shift of visual attention toward threatening stimuli in the environment, such as facial expressions (Mogg & Bradley, 1999). More recent evidence, however, indicates that anxiety may be better characterized by a failure to rapidly disengage the visual attention system away from threat-related facial expressions (Fox, Russo, Bowles, & Dutton, 2001). The present study further investigates this delayed disengagement hypothesis. Results show that high trait-anxious individuals, in contrast to low trait-anxious individuals, take longer to classify peripheral target letters when fearful facial expressions were presented at fixation relative to sad, happy, or neutral expressions. These findings demonstrate a specific tendency to dwell on fear-relevant stimuli, as opposed to negative information in general. These findings are considered from an evolutionary perspective and the possible role of delayed disengagement from threat in the maintenance of anxiety states is also discussed.  相似文献

This study examined relations between the incidence of workplace bullying and the everyday experiences of members of ethnic and racial minorities in the American workplace. Particular attention was paid to expressions of bullying that overtly or specifically refer to race or ethnicity, in the form of more or less subtle acts of discrimination and hostile treatment, introducing the term `racial/ethnic bullying.' Participants belonging to four racial/ethnic groups (Asians, African-Americans, Hispanics/Latinos, and whites) responded to a written survey of general and racial/ethnic bullying experiences, responses, and preferred modes and methods of internal organizational redress and dispute resolution. Very different profiles emerged between bullying perpetrated by supervisors/superiors versus co-workers/peers in the organization.  相似文献

This study was designed to assess jury decision-making for 289 participants reading a medical malpractice vignette as a function of participant type (undergraduate students or jury panelists), punitive damage award apportionment (none, half, or all to the plaintiff), and compensation previously assigned to the plaintiff (low, medium, or high). We found several sample differences. Overall, jury panelists awarded more money for punitive damages. Jury panelists were also more affected by compensatory-relevant information when making punitive decisions, including assigning punitive damages and rating the fairness of the traditional apportionment scheme, where the plaintiff receives all of the money. Compared with students, more jury panelists were in favor of the plaintiff receiving the entire punitive award. Most students endorsed split recovery. The authors suggest that psycholegal research conducted solely with student samples, rather than community members, may misestimate the likely behavior of actual juries. The implications of the study for split recovery policy are also discussed.  相似文献

The GluR1 subunit of the AMPA receptor is required for hippocampal-dependent memory formation, emotional learning and synaptic plasticity. Recent work has shown that GluR1-independent synaptic plasticity is mediated by nitric oxide. Nitric oxide activity is influenced by estrogen. It is unknown whether this gender-dependent effect conveys a gender dimorphic requirement of GluR1 for learning. This hypothesis was tested in two behavioral paradigms. In Experiment 1, the retention of contextual fear conditioning was impaired in male but not female GluR1 knockout mice. In Experiment 2, GluR1 knockout mice made significantly more arm entry errors during acquisition of a radial-arm watermaze task. This deficit was independent of gender. These results indicate that some forms of learning are gender dimorphic in GluR1 knockout mice. The results are discussed with reference to task and gender-specific interactions between GluR1 receptor intracellular signalling pathways.  相似文献

Although infants display preferences for social stimuli early in their lives, we know relatively little about the mechanisms of infant learning about the social world. In the current set of studies, 1-month-old infants underwent an adapted eyeblink conditioning paradigm to examine learning to both 'social' and non-social cues. While infants were asleep, they were presented with either a 'social' stimulus (a female voice) or one of two non-social stimuli (tone or backward voice) followed by an airpuff presented to the eyelid. Infants in the experimental groups displayed increased learning across trials, regardless of stimulus type. However, infants conditioned to the 'social' stimulus showed increased learning compared to infants conditioned to either of the non-social stimuli. These results suggest a mechanism by which learning about the social world occurs early in life and the power of ecologically valid cues in facilitating that learning.  相似文献

Economists define risk in terms of the variability of possible outcomes, whereas clinicians and laypeople generally view risk as exposure to possible loss or harm. Neuroeconomic studies using relatively simple behavioral tasks have identified a network of brain regions that respond to economic risk, but these studies have had limited success predicting naturalistic risk-taking. By contrast, more complex behavioral tasks developed by clinicians (e.g. Balloon Analogue Risk Task and Iowa Gambling Task) correlate with naturalistic risk-taking but resist decomposition into distinct cognitive constructs. We propose here that to bridge this gap and better understand neural substrates of naturalistic risk-taking, new tasks are needed that: are decomposable into basic cognitive and/or economic constructs; predict naturalistic risk-taking; and engender dynamic, affective engagement.  相似文献

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age.  相似文献

Hearing and repeating novel phonetic sequences, or novel nonwords, is a task that taps many levels of processing, including auditory decoding, phonological processing, working memory, speech motor planning and execution. Investigations of nonword repetition abilities have been framed within models of psycholinguistic processing, while the motor aspects, which also are critical for task performance, have been largely ignored. We focused our investigation on both the behavioral and speech motor performance characteristics of this task as performed in a learning paradigm by 9‐ and 10‐year‐old children and young adults. Behavioral (percent correct productions) and kinematic (movement duration, lip aperture variability – an index of the consistency of inter‐articulator coordination on repeated trials) measures were obtained in order to investigate the short‐term (Day 1, first five vs. next five trials) and longer‐term (Day 1 vs. Day 2, first five vs. next five trials) changes associated with practice within and between sessions. Overall, as expected, young adults showed higher levels of behavioral accuracy and greater levels of coordinative consistency than the children. Both groups, however, showed a learning effect, such that in general, later Day 1 trials and Day 2 trials were shorter in duration and more consistent in coordination patterns than Day 1 early trials. Phonemic complexity of the nonwords had a profound effect on both the behavioral and speech motor aspects of performance. The children showed marked learning effects on all nonwords that they could produce accurately, while adults’ performance improved only when challenged by the more complex nonword stimuli in the set. The findings point to a critical role for speech motor processes within models of nonword repetition and suggest that young adults, similar to children, show short‐ and longer‐term improvements in coordinative consistency with repeated production of complex nonwords. There is also a clear developmental change in nonword production performance, such that less complex novel sequences elicit changes in speech motor performance in children, but not in adults.  相似文献

Although parents and children are thought to influence one another's affect and behavior, few studies have examined the direction of effects from children to parents, particularly with respect to parental psychopathology. We tested the hypothesis that children's affective characteristics are associated with the course of mothers' depressive symptoms. Children's affect expression was observed during a series of mother-child interaction tasks, and children's resting frontal electroencephalogram (EEG) asymmetry was assessed in a psychophysiology laboratory. Mothers' depressive symptoms were assessed at two time points, approximately one year apart, at the mother-child interaction visits. Depressive symptoms increased over time for mothers with a history of childhood-onset depression whose children exhibited right frontal EEG asymmetry. Depressive symptoms were associated with high child negative affect at both time points for mothers whose children exhibited right frontal EEG asymmetry. Cross-lagged models with a subset of participants provided some evidence of both parent-to-child and child-to-parent directions of effects. Findings suggest that akin to other interpersonal stressors, children's affective characteristics may contribute to maternal depressive symptoms.  相似文献
