Electrophysiological examination of embodiment in vision and action

A wealth of behavioral data has shown that the visual properties of objects automatically potentiate motor actions linked with them, but how deeply are these affordances embedded in visual processing? In the study reported here, we used electrophysiological measures to examine the time course of affordance resulting from the leftward or rightward orientation of the handles of common objects. Participants were asked to categorize those objects using a left- or right-handed motor response. Lateralized readiness potentials showed rapid motor preparation in the hand congruent with the affordance provided by the object only 100 to 200 ms after stimulus presentation and up to 400 ms before the actual response. Examination of event-related potentials also revealed an effect of handle orientation and response-hand congruency on the visual P1 and N1 components. Both of these results suggest that activity in the early sensory pathways is modulated by the action associations of objects and the intentions of the viewer.     

Investigating the true rate of physical intimate partner violence: A review of nationally representative surveys

This review systematically investigates rates of physical intimate partner violence for both sexes in international samples. Surveys that accessed nationally representative samples, used gender inclusive methodology and neutral contexts are reviewed to determine 12-month and lifetime victimization and perpetration rates. Discrepancies between international rates, and the impact that gender equality may have upon these differences is also investigated. Electronic databases were systematically searched to identify surveys that met inclusion criteria. Eleven surveys were reviewed. Of these, Family Violence surveys had the highest methodological quality and showed equal rates for both sexes. Surveys of lesser quality typically showed higher female victimization and male perpetration rates. Countries at the extremes of gender empowerment measure scores differed in their patterns of rates. Gender equality in the US was associated with symmetry for the sexes, and inequality in Uganda associated with higher female victimization. However, as countries tended to use different methods to investigate the problem it was not possible to compare the effects of gender equality on differences in international rates of IPV. It is concluded that survey methodology needs to be consistent across nations, and specifically target family violence if true rates are to be determined and compared across the globe.     

Assessing the evidence for response time mixture distributions

I describe a technique for comparing two simple accounts of a distribution of response times: A mixture model and a generalized-shift model. In the mixture model, a target distribution is assumed to be a mixture of response times from two other (reference) distributions. In the generalized-shift model, the target distribution is assumed to be a quantile average of the reference distributions. In order to distinguish these two possibilities, quantiles for the target distribution are estimated from the quantiles of the reference distributions assuming either a shift or a mixture, and the predicted quantiles are used to calculate the multinomial likelihood of the obtained data. Monte Carlo simulations reported here demonstrate that the index is relatively unbiased, is effective with moderate sample sizes and modest spreads between the reference distributions, is relatively unaffected by changes in the number of bins or by data trimming, can be used with data aggregated across subjects, and is relatively insensitive to a range of subject variations in distribution shape and in mixture or shift proportion. As an illustration, the index is applied to the interpretation of three effects from distinct paradigms: residual switch costs in the task-switching paradigm, the psychological refractory period effect, and sequential effects in the Simon task. I conclude that the multinomial likelihood index provides a useful and easily applied tool for the interpretation of effects on response time distributions.     

Bridging the Distance Between Us: How Initial Responses to Sales Team Conflict Help Shape Core Selling Team Outcomes

Intra-team conflict within core selling teams can shape team outcomes. Using congruency theory, we propose how conflict responses impact the relational distance between individuals in a core selling team, creating positive/negative team outcomes. Our framework suggests managers may improve team outcomes by monitoring sales team members' responses to conflict, encouraging internal cognitive voice behaviors, and intervening in teams not using internal cognitive voice behaviors when relational or process conflict exists. Our model helps explain the paradox in which an individual who is part of a “winning” team (one achieving its team goals) may still choose to exit the team.     

Dysfunctional Behavior among Sales Representatives: The Effect of Supervisory Trust,Participation, and Information Controls

This study investigates the efficacy of supervisory trust, participation, and information controls in curbing dysfunctional salesperson behavior so that salesperson actions are in line with organizational goals. Using a sample of 210 salespeople, we develop and test a model incorporating supervisory trust, participation, information controls (output information, activity information, and capability information), and dysfunctional behavior. Output and activity information controls directly affect dysfunctional behavior, whereas capability information controls work positively through trust in the supervisor to reduce dysfunctional behavior. Providing sales representatives with information about their capabilities appears to enhance the supervisor–salesperson trust relationship. Results also indicate that salespeople’s supervisory participation is an effective lever for reducing dysfunctional salesperson behavior through the intervening role of trust in the supervisor.     

Key Accounts and Team Selling: A Review,Framework, and Research Agenda

As sales organizations increase their reliance on sales teams, they must learn how organizational and interpersonal relationships influence sales teams, how sales teams play a learning role for organizations, and what makes sales teams effective. Presenting a model of interrelationships among members of the selling firm and between the selling and buying firms, we identify five key team selling relationships between (1) members of the same team, (2) members of different teams within the firm, (3) the selling team and the buying center, (4) the selling team and other groups in the selling firm, and (5) the selling team and the firm’s strategy. This model leads to a conceptual framework highlighting relationship drivers, factors, and outcomes instrumental to team selling success. After presenting propositions for future research, theoretical and methodological suggestions are included to facilitate research in this area. We conclude with perspectives on the future of research and practice in key accounts and team selling.     

An examination of gender differences in the construct validity of the silencing the self scale

Jack’s (1991) theory of self-silencing was originally designed to explain higher rates of depression in women in comparison to men. However, research finding that men score equal or even higher than women on measures of self-silencing has lead theorists to speculate that self-silencing tendencies may be driven by different motivations and have different consequences for women versus men (Jack & Ali, 2010). Using a sample of 247 college students, we examined gender differences in the construct validity of the Silencing the Self Scale (STSS; Jack & Dill, 1992). We hypothesized that women would score higher on the Externalized Self-Perception subscale, but not the other three subscales. Gender differences in the relationship between the STSS subscales and theoretically-relevant constructs were also explored. The results indicated that women on average scored higher than men on the Externalized Self-Perception subscale, whereas men scored higher on the Care as Self-Sacrifice subscale. Further, there was a significant Gender × Care as Self-Sacrifice subscale interaction in the prediction of depression, such that this subscale was negatively correlated to depression in men, and uncorrelated in women. These results clarify how self-silencing might translate into different mental health outcomes for women and men.     

Systematically identifying implicit theories in male and female intimate partner violence perpetrators

This review systematically examines the empirical literature to determine the support available for seven proposed Implicit Theories (ITs) held by heterosexual male and female perpetrators of intimate partner violence. Based on previous literature that has hypothesized and identified ITs in intimate partner violence (IPV) and other types of offenders, we suggest six potential ITs likely to be held by men and women: “Opposite sex is dangerous”, “Relationship entitlement”, “General entitlement”, “Normalization of relationship violence”, “Normalization of violence”, and “It's not my fault”. We suggest one extra IT held by male perpetrators: “I am the man”. Electronic databases were searched from 1980 onwards, using predetermined relevant key words, to identify IPV research that has examined factors associated with each of the proposed seven ITs. Support was found for the existence of all seven ITs, but it differed in terms of strength, mainly due to the dearth or poor quality of empirical research on specific areas, especially in female perpetrated IPV. Implications for treatment and future directions are discussed.     

A survey of the views of trainees in psychiatry regarding religious issues

Abstract

Although 94% of Americans believe in God, little is known about the religiosity of psychiatric residents and the role of religion in residents’ practice. We aimed to determine residents’ perceptions about (1) the importance of knowledge of religious beliefs, practices and priority of psychotherapy, psychopharmacology and general medical patients and (2) the relative difficulty religious issues presented compared with race, age, gender and sexuality.

All psychiatric trainees in one training program during two academic years were surveyed (n = 96). The 38 respondents (40%) reported a substantial degree of religiosity [high belief (74%), high practise (50%), high priority (71%)]. Significantly more residents reported that it was more important to know about the religiosity of psychotherapy patients than of psychopharmacology or general medical patients. Race was the only issue that the majority of residents reported as presenting more difficulty than religion.

In conclusion, the subgroup of residents who responded to the survey were more religious than expected, based on previous surveys of psychiatrists. They clearly differentiated psychotherapy patients from others when considering the importance of religion. That residents viewed religion to be a challenging issue underlines the need for further training and clinical focus on religion.
