Preparing for perception and action (II): Automatic and effortful processes in response cueing

In this paper we tested the automatic-effortful processing assumption of the Grouping Model. According to the Grouping Model, left-right cues are pull cues and inner-outer cues are push cues, evoking exogenous and endogenous control, respectively. In a series of four experiments we manipulated the characteristics of the cues: Onset vs. no-onset cues, spatial vs. symbolic cues, valid vs. invalid cues. The results consistently showed a dissociation between left-right and inner-outer cues. Together, the present findings provide converging evidence for the notion that left-right cues induce a fast, automatic selection of the cued responses, whereas inner-outer cues need slower, effortful processes to establish a selective preparatory set.     

Representations in working memory yield interference effects found with externally-triggered representations

An act as simple as flicking a switch involves various stages of processing. Each stage is susceptible to interference from competing representations/processes. Interference at different stages of processing (e.g., perceptual stages versus response selection stages) leads to distinct behavioral, neural, and subjective effects. In the flanker task, for instance, one responds to a visual target and disregards flanking ‘distractors.’ Theoretically-predicted interference (increased response times, error rates, and subjective ‘urges to err’) is stronger when distractors and targets are associated with different actions (response interference) than when they look different but are associated with the same action (perceptual interference). Extant versions of the task tax working memory (WM) minimally, but many everyday actions (e.g., searching for keys or holding one's breath) require more WM-based control. To illuminate this uncharted area, we examined the nature of interference in delayed action tasks, which rely on WM. We found that systematic interference arises even when action-related representations are, not triggered solely by external stimuli, but actively held in WM. We discuss these findings with increased emphasis on the under-explored subjective effects of different kinds of interference. The implications of these findings for the study of action production, WM, and conscious processing are entertained.     

Spouses' Cortisol Associations and Moderators: Testing Physiological Synchrony and Connectedness in Everyday Life

In this study, associations were examined between cortisol levels of wives and husbands in 47 heterosexual married couples. Both partners' salivary cortisol levels were measured at the same moments seven times a day on 2 typical weekdays. After accounting for the effects of the diurnal rhythm of cortisol and relevant control variables, dyadic hierarchical linear modeling indicated significant positive linkages between partners' cortisol levels, consistent with the hypothesized within‐couple physiological synchrony. Variables reflecting more (spousal presence) or less connectedness (loneliness, being alone) were also collected at the time of each cortisol sample. Results indicated that husbands' cortisol levels were higher at moments they reported feeling lonelier and lower at moments they were in the presence of their spouse. Wives' cortisol levels were higher at moments they were alone. In addition, wife–husband cortisol synchrony was stronger for husbands who spent relatively more time with their spouse across the study period—even after accounting for time spent with others in general. These findings suggest that marital partners evidence positive within‐couple cortisol associations, and that connectedness (particularly physical closeness) may underpin spouses' physiological synchrony.     

Military service and moral obligation∗

The author investigates the view that there is a moral obligation to serve in the armed forces of the nation State of which one is a citizen resident (with special reference to young American men at the present time). It is conceded that under current law in this country there may be such a legal obligation, that many men may be obliged to render such service, and that under certain circumstances even a moral obligation to serve may also exist. What is denied is that any of the familiar theories of moral obligation is adequate in existing circumstances to establish this thesis in general. The result is either that a new theory of moral obligation must be developed to fit the current facts, or the present assessment of those facts must be fundamentally revised, or we must concede that draftees and men generally have no such moral obligation of service at all.     

“Tell Me Who Your Enemies Are”: Government Reports About the “Cult” Phenomenon in Israel

Between 1982 and 2011, four Israeli governmental reports addressing ostensible dangers from “cults” (new religious movements, or NRMs) were issued. The 1980s reports use a collectivist discourse, in which the state sees itself as defending the collective's borders from external threats and representing various sectors while seeking consensual values. The 1990s report marks an interim stage in which the state tries to balance individual liberties with sectoral interests. The 2011 report focuses solely on harm to individuals and is the harshest of the four. The reports reflect milestones in three processes of change that have taken place in Israeli society: from a collectivist‐hegemonic ethos to a multisectoral one; from a focus upon society to a focus on the individual; and from nationalistic values to universalistic ones. At every point in time, NRMs represented a different perceived threat to Israeli society. We explain how multisectoralism brings about both tolerance toward new religious phenomena and fierce anti‐cultic activity.     

Navigating conflict and power at work: the effects of power and interdependence asymmetries on conflict in organizations

Many of the most difficult conflicts people face at work are up and down; with bosses, supervisors, and important clients, or with direct reports, staff, or other employees who differ from them in terms of their power and interests. However, much of the research on power differences and conflict tends to be piecemeal, decontextualized, and focused on negative consequences. This paper presents 2 studies that investigated a new situated model of conflict and power at work. They build on classic areas of research on social conflict, power, and interdependence; and integrate them into a coherent framework for organizational conflict research. The study methods and findings are presented, and their implications for research on work conflict are discussed.     

Distractor Interference in Selective Reaching: Dissociating Distance and Grouping Effects

In the present experiment, the authors sought to differentiate between a distance and a grouping explanation for the symmetric versus asymmetric patterns of distractor interference in selective reaching. Participants (N = 16) pointed to a green target that appeared either with or without a red distractor. Target-distractor separation was manipulated within an array of 5 closely grouped stimulus boxes, and distractor interference (difference in performance between trials with and trials without a distractor) was measured in reaction time, movement time, percentage errors, and movement endpoints. Small distances (5 mm) between target and distractor yielded a symmetric pattern of interference, whereas large distances (20 mm) yielded an asymmetric pattern, with more interference from near than from far distractors. Those findings support the distance account of distractor interference and refute the grouping account.
