This study investigates how people weight potential relationship partners' personal characteristics (i.e., warmth and competence) when deciding to initiate professional versus personal network relationships, and it also examines how certain personality traits (extraversion and conscientiousness) shape this process. Results from two samples indicate that people tend to value competence more highly when initiating professional relationships, whereas they tend to value warmth more highly when initiating personal relationships. Furthermore, neither extraversion nor conscientiousness was related to how people weighted competence when initiating professional relationships. However, supplementary analyses demonstrated that people high in conscientiousness tend to value competence and people high in agreeableness tend to value warmth in their network relationship partners, regardless of whether they are initiating a professional or personal relationship. 相似文献

Individuals responsible for carrying out research within their diverse communities experience a critical need for research ethics training materials that align with community values. To improve the capacity to meet local human subject protections, we created the research Ethics Training for Health in Indigenous Communities (rETHICS), a training curriculum aligned within American Indian and Alaska Native (AI/AN) context, culture, and community‐level ethical values and principles. Beginning with the Belmont Report and the Common Rule that defines research with human subjects (46 CFR 45), the authors convened three different expert panels (N = 37) to identify Indigenous research values and principles common across tribal communities. The resulting culturally grounded curriculum was then tested with 48 AI/AN individuals, 39 who also had recorded debriefing interviews. Using a thematic analysis, we coded the qualitative feedback from the expert panel discussions and the participant debriefings to assess content validity. Participants identified five foundational constructs needed to ensure cultural‐grounding of the AI/AN‐specific research training curriculum. These included ensuring that the module was: (a) framed within an AI/AN historical context; (b) reflected Indigenous moral values; (c) specifically linked AI/AN cultural considerations to ethical procedures; (d) contributed to a growing Indigenous ethics; and (e) provided Indigenous‐based ethics tools for decision making. Using community‐based consultation and feedback from participants led to a culturally grounded training curriculum that teaches research ethical principles and procedures for conducting research with AI/ANs. The curriculum is available for free and the community‐based process used can be adapted for other cultural groups. 相似文献

In a test of two key features of REBT, causal relationships between irrational beliefs and unconditional self-acceptance were
experimentally investigated in a sample of 106 non-clinical participants using a priming technique. Priming participants with
statements of irrational belief resulted in a decrease in unconditional self-acceptance whereas priming participants with
statements of rational belief resulted in an increase in unconditional self-acceptance. In contrast, priming participants
with statements about unconditional self-acceptance did not result in an increase in rational thinking and priming participants
with statements about conditional self-acceptance did not result in an increase in irrational thinking. The present study
is the first to provide evidence of a causal link between rational/irrational thinking and unconditional/conditional self-acceptance.
The findings have important implications for the core hypothesis of REBT and underscore the advantages of experimental over
correlational studies in theory-testing. 相似文献

This study examined how children's insecure internal representations of interparental and parent-child relationships served as explanatory mechanisms in multiple pathways linking interparental conflict and parent emotional unavailability with the emotional and classroom engagement difficulties the children had in their adjustment to school. With their parents, 229 kindergarten children (127 girls and 102 boys, mean age = 6.0 years, SD = .50, at Wave 1) participated in this multimethod, 3-year longitudinal investigation. Findings revealed that children's insecure representations of the interparental relationship were a significant intervening mechanism in associations between observational ratings of interparental conflict and child and teacher reports on children's emotional and classroom difficulties in school over a 2-year period. Moreover, increased parental emotional unavailability accompanying high levels of interparental conflict was associated with children's insecure representations of the parent-child relationship and children's difficulties in classroom engagement at school entry. The findings highlight the importance of understanding the intrinsic processes that contribute to difficulties with stage-salient tasks for children who are experiencing interparental discord. 相似文献

We investigated the independent contributions of maternal history of antisocial behavior and parenting practices to the worsening course of sons' behavior problems in a sample of young urban boys at risk for antisocial behavior. Mothers reported on boys' behavior problems at baseline and one year later, as well as on their own history of antisocial behavior before and after age 15, and of lifetime depression and substance use disorders (provisional DSM-III-R diagnoses). Baseline reports of parenting practices were obtained. Lower involvement, lower monitoring, and higher levels of parent–child conflict and maternal Conduct Disorder (CD) before age 15 contributed to the worsening of boys' behavior problems one year later; mothers' symptoms of Antisocial Personality Disorder after age 15 did not. Mothers' lifetime history of Major Depression and Substance Use Disorder did not add to the worsening of boys' behavior problems after accounting for these other factors. Although maternal CD contributed directly to the worsening of boys' behavior problems, the effect of parenting was more substantial. We discuss clinical implications for prevention and treatment of children's antisocial behavior, and intergenerational implications of girls' early antisocial behavior. 相似文献

The fundamental hypothesis of the disease model of nicotine addiction states that, following a regime of chronic smoking,
further smoking becomes a pharmacologically compelled rather than a chosen act. Despite it’s public and professional popularity
as an explanation for why people continue to smoke in spite of a deteriorating quality of life, the validity of this hypothesis
has been critically undermined by the state of evidence in four domains: inconclusive empirical evidence of withdrawal severity
as a potent predictor of quit outcome; methodological problems concerning the measurement of factors which maintain smoking;
logical problems with the interpretation of factors which maintain smoking, in particular, failures to discriminate reflexive
and mediated actions in explanations of why people smoke; and philosophical problems with conceptualisations of human action
as determined rather than willed. In light of these problems, it is argued that evidence on the nature of nicotine addiction
is not well explained by the disease model, but rather, posits smoking primarily as a decision-making process influenced peripherally
by the pharmacologic effects of nicotine on the brain and body.

The Child Behavior Checklist (CBCL/6-18) is a widely used parent-report measure of youth internalizing and externalizing problems.
Accumulating evidence, however, suggests that the CBCL may not adequately assess clinical problems in diverse populations.
We investigated the measurement equivalence (ME) of the CBCL in an African American adolescent sample (N = 145). Confirmatory factor analysis indicated poor factor model fit; however, modification indices and an alternative two-factor
model produced improved fit statistics. Internal consistency coefficients of CBCL scales ranged from α = .65 to .88 and were generally lower than those reported for the normative sample. The CBCL exhibited convergent validity
with conceptually similar scales on the Parent Report Scale of the Behavior Assessment System for Children; however, the correlations
were weaker than those reported for the normative sample. The CBCL Internalizing composite failed to predict clinician-rated
Emotional problems, however, the Externalizing composite predicted clinician-rated behavior problems. In summary, the CBCL
did not exhibit unequivocal evidence of ME, as it both possesses and lacks a number of statistical attributes that would demonstrate its equivalence with African Americans. Future empirical
and theoretical work is discussed. 相似文献

The amygdala is not necessary for unconditioned stimulus inflation after Pavlovian fear conditioning in rats 下载免费PDF全文

The basolateral complex (BLA) and central nucleus (CEA) of the amygdala play critical roles in associative learning, including Pavlovian conditioning. However, the precise role for these structures in Pavlovian conditioning is not clear. Recent work in appetitive conditioning paradigms suggests that the amygdala, particularly the BLA, has an important role in representing the value of the unconditioned stimulus (US). It is not known whether the amygdala performs such a function in aversive paradigms, such as Pavlovian fear conditioning in rats. To address this issue, Experiments 1 and 2 used temporary pharmacological inactivation of the amygdala prior to a US inflation procedure to assess its role in revaluing shock USs after either overtraining (Experiment 1) or limited training (Experiment 2), respectively. Inactivation of the BLA or CEA during the inflation session did not affect subsequent increases in conditioned freezing observed to either the tone conditioned stimulus (CS) or the conditioning context in either experiment. In Experiment 3, NBQX infusions into the BLA impaired the acquisition of auditory fear conditioning with an inflation-magnitude US, indicating that the amygdala is required for associative learning with intense USs. Together, these results suggest that the amygdala is not required for revaluing an aversive US despite being required for the acquisition of fear to that US.Pavlovian fear conditioning in rats is a behavioral model used to investigate the neurobiology underlying the development and maintenance of fear learning and memory (Grillon et al. 1996; LeDoux 1998, 2000; Bouton et al. 2001; Maren 2001b, 2005; Kim and Jung 2006). In this model, an innocuous conditioned stimulus (CS), such as a tone, is paired with an aversive unconditioned stimulus (US), such as a footshock. After one or more pairings, the rat learns that the CS predicts the US. As a consequence, CS presentations alone elicit a conditioned fear response (CR), which includes increases in heart rate, arterial blood pressure, hypoalgesia, potentiated acoustic startle, stress hormone release, and freezing (somatomotor immobility).The amygdala has been identified as one of the major regions in which fear memories are encoded and stored. Within the amygdala, the basolateral complex of the amygdala (BLA; consisting of the lateral, basolateral, and basomedial nuclei) and the central nucleus of the amygdala (CEA) receive convergent CS and US information and are involved in the acquisition of fear memories (LeDoux 1998, 2000; Fendt and Fanselow 1999; Davis and Whalen 2001; Maren 2001b; Schafe et al. 2001; Fanselow and Gale 2003; Wilensky et al. 2006; Zimmerman et al. 2007). In addition, the CEA has an important role in the expression of fear CRs (Fendt and Fanselow 1999; LeDoux 2000; Davis and Whalen 2001; Maren 2001b; Fanselow and Gale 2003). In support of this, many studies have shown that either permanent or temporary lesions of the BLA or CEA prevent the acquisition and/or expression of fear memories (Helmstetter 1992; Helmstetter and Bellgowan 1994; Campeau and Davis 1995; Maren et al. 1996a,b; Killcross et al. 1997; Muller et al. 1997; Walker and Davis 1997; Cousens and Otto 1998; Maren 1998, 1999, 2001a,b; Wilensky et al. 1999, 2000, 2006; Goosens and Maren 2001, 2003; Nader et al. 2001; Fanselow and Gale 2003; Gale et al. 2004; Koo et al. 2004; Zimmerman et al. 2007).In addition to its role in encoding CS–US associations during conditioning, recent work suggests that the amygdala is also involved in representing properties of the US itself. For example, temporary or permanent lesions of the BLA reduce both decrements in conditioned responding after devaluation of a food US (Hatfield et al. 1996; Killcross et al. 1997; Blundell et al. 2001; Balleine et al. 2003; Everitt et al. 2003; Pickens et al. 2003; Holland 2004) and increments in conditional responding after inflation of a shock US (Fanselow and Gale 2003). Moreover, recent electrophysiological studies in primates indicate that amygdala neurons represent the value of both aversive and appetitive outcomes (Paton et al. 2006; Belova et al. 2007, 2008; Salzman et al. 2007). These studies suggest that one function of the BLA is to represent specific properties of biologically significant events, such as the food or shock USs that are typically used in Pavlovian conditioning paradigms. By this view, the BLA may represent specific sensory properties of USs that shape the nature of learned behavioral responses to the US (Balleine and Killcross 2006) and allow CSs to gain access to the incentive value of the US (Everitt et al. 2003).In contrast to this view, we recently reported that rats with neurotoxic BLA lesions exhibit normal US revaluation after Pavlovian fear conditioning (Rabinak and Maren 2008). In this study, auditory fear conditioning (75 CS–US trials) with a moderate footshock (1 mA) was followed by several exposures (five US-alone trials) to an intense footshock (3 mA) during an inflation session. Both intact rats and rats with BLA lesions exhibit a robust increase in conditional freezing to the auditory CS during a subsequent retention test (Rabinak and Maren 2008). Control experiments suggested that this was due to a revaluation of the US with which the CS was associated, rather than nonassociative sensitization of fear engendered by exposure to intense shock. These data reveal that the BLA may not be necessary for representing properties of shock USs during Pavlovian fear conditioning. To address these issues further, we have examined the consequence of reversible pharmacological manipulations of the amygdala during US inflation on conditional fear responses established with either extensive or limited training. 相似文献
