The effect of trial-to-trial feedback on the error-related negativity and its relationship with anxiety

Individuals with anxiety disorders and related personality traits are characterized by increased error-related brain activity, as measured by the error-related negativity (ERN) in simple speeded response tasks. An absent, or opposite, relation between anxiety and the ERN has been reported in studies that employed reinforcement learning paradigms with trial-to-trial feedback. Understanding the effect of trial-to-trial feedback on the ERN may help clarify these results and can further elucidate the impact of feedback on performance monitoring. In the present study, 30 undergraduate participants performed two versions of the arrowhead version of the flanker task in counterbalanced order: one with trial-to-trial feedback and one without. The participants were slower and more accurate in the task with trial-to-trial feedback; however, the ERN was equivalent between the two tasks. Larger ERNs were related to higher trait anxiety, but only in the version without trial-to-trial feedback. These findings show that although trial-to-trial performance feedback impacts behavioral measures, it does not affect the ERN; moreover, the presence of trial-to-trial feedback moderates the relationship between the ERN and anxiety.     

Absolute Versus Tentative Interpretations: Mediating Effects of Client Locus of Control

An analog design was used to investigate the mediating effects of client locus of control (i.e., an internal focus or external focus) on perceptions of counselor style of interpreting events (i.e., absolute or tentative interpretations) on measures of perceived session depth and smoothness, and perceived counselor expertness, attractiveness, and trustworthiness. One hundred and thirty-four undergraduate college students, crossed on level of locus of control, were randomly assigned to one of two treatment conditions, and then completed measures of perceived session depth and smoothness, as well as perceived counselor expertness, attractiveness, and trustworthiness. Results indicated a significant interaction effect on perceived counselor trustworthiness. Implications for college counselors are provided.     

Motivation to Manage in China and Hong Kong: A Gender Comparison of Managers

Although women comprise an important part of the labor force in Hong Kong and the People's Republic of China (PRC), they remain underrepresented and underutilized in managerial positions. This study investigates the applicability of role motivation theory in the Chinese culture and examines if lack of motivation to manage is a potential explanation for this underrepresentation. Data were collected from 127 Hong Kong (68 men and 59 women) and 175 mainland Chinese (128 men and 47 women) managers. As expected, Hong Kong managers possess significantly higher levels of motivation to manage than do their PRC counterparts. There are, however, no significant gender-based differences in levels of motivation to manage in either Hong Kong or the PRC. Lack of motivation to manage does not appear to contribute to the underutilization of Chinese women in management in Hong Kong and mainland China.     

Token Majority: The Work Attitudes of Male Flight Attendants

This study examined the work experiences of men, a traditional workplace majority, as minority members of a female-dominated occupation. We used tokenism and social categorization theories to propose and test a set of hypotheses that link token status (a less than 15% minority) with male flight attendants' work attitudes through intervening psychological and job factors. Survey data from a sample of 236 male and female flight attendants supported a model in which a negative relationship between token status and the work attitudes of job satisfaction and organizational attachment was mediated by low self-esteem, increased role ambiguity, and poor job fit. The uncovering of these previously unmeasured intervening variables strengthens theoretical connections between demography and work outcomes and suggests leverage points for improving the work attitudes of individuals in the minority.     

Prenatal testosterone treatment potentiates the aggression‐inhibiting effect of the neurosteroid dehydroepiandrosterone in female mice

The neurosteroid dehydroepiandrosterone (DHEA) is a powerful inhibitor of aggression in murine models when given for 15 days and potentially may be useful in the management of inappropriate human aggression. Although the biosynthesis and metabolism of DHEA have been described, little is known about the potential effect of the steroidal environment during sexual differentiation on the subsequent response to DHEA. Whether prenatal androgen exposure influences the subsequent response to DHEA was assessed by comparing the effect of DHEA (80 μg/d) on aggression in female offspring where dams were treated with 1, 10, or 100 μg of testosterone (T) on days 15 to 18 of gestation (Experiment I) or that developed in different uterine positions (Experiment II). The results showed that DHEA decreased attack behavior in general and that the 100‐μg prenatal T treatments enhanced the antiaggressive effect of this neurosteroid. Neither the lower doses of exogenously administered T nor the uterine position led to an enhanced response to DHEA. In addition, whether DHEA produced changes in social and nonsocial activities was examined. In the 100‐μg T females, DHEA increased the duration of the former and decreased the frequency and duration of the latter, indicating that it was not a general decrement in behavioral expression that mediated the enhanced response to the antiaggressive effect of DHEA. In the second experiment, DHEA treatment led to increased frequencies of social nonaggressive and nonsocial activities. However, the uterine positions × treatment interactions were not significant, demonstrating that contiguity to male fetuses did not differentially affect the response to DHEA. Aggr.

Breathwork as a Therapeutic Modality: An Overview for Counselors

Using the breath as a vehicle for accessing psychological material is a topic rarely discussed in the counseling literature, despite the use of conscious engagement with the breath by many spiritual traditions for the purpose of personal transformation. This article describes 3 types of conscious breathing (circular breathing, conscious connected breathing, and fast and full breathing) and the use of therapeutic breathwork within the counseling process. The authors describe the many facets of the breathwork experience, provide a case study, and address clinical considerations when engaging in breathwork with clients.     

RELATIVISM AND ANTI-REALISM

I characterise a relativist account of truth as one according to which the truth value of a sentence can vary without its meaning changing. Relativism is to be contrasted with absolutism, which states that the truth values of sentences cannot change, so long as their meanings remain constant. I argue that absolutism follows from the realist account of meaning and truth conditions. According to realism, the meaning of a sentence consists in objective truth conditions and sentences are true if and only if certain objective conditions obtain. Relativism is a consequence of anti-realism. Anti-realists believe that the meanings of sentences consist in recognisable conditions and that sentences are true if and only if certain recognisable conditions obtain. I contrast the sorts of relativism which results from partial, empiricism-based anti-realisms, and global anti-realism, which is linked to a coherence theory of knowledge. I offer a few remarks on how global anti-realists can restrict the scope of their relativism.     

Effects of association and imageability on phonological mapping

In two experiments, we examined the influence of semantic activation on the generation of a phonological code, testing the interactivity assumption common to both dual-route and interactive-activation models. In Experiment 1, subjects named regular and irregular targets preceded by related and unrelated primes. In Experiment 2, these variables and target imageability were manipulated. Both relatedness and imageability interacted with regularity, indicating that semantic activity speeds access to a phonological code.
