Just the thought of it!: Effects of anticipating computer-mediated communication on gender stereotyping

A study investigated how anticipated communication mode affects the use of stereotypes in forming impressions and making task assignments. Participants rated male or female targets with whom they envisioned working on a business project using computer-mediated or face-to-face modes of communication. Results indicated that both men and women were characterized more stereotypically when participants anticipated working with them electronically than when they anticipated working with them face-to-face. Furthermore, task assignments were more often gender stereotype consistent when the communication mode was computer-mediated than when it was face-to-face. These findings suggest that the mere anticipation of computer-mediated communication, without the actual the experience of it, is enough to promote stereotypes and biased decision-making.     

Distributed recognition of natural songs by European starlings

Individual vocal recognition behaviors in songbirds provide an excellent framework for the investigation of comparative psychological and neurobiological mechanisms that support the perception and cognition of complex acoustic communication signals. To this end, the complex songs of European starlings have been studied extensively. Yet, several basic parameters of starling individual vocal recognition have not been assessed. Here we investigate the temporal extent of song information acquired by starlings during vocal recognition learning. We trained two groups of starlings using standard operant conditioning techniques to recognize several songs from two conspecific male singers. In the first experiment we tested their ability to maintain accurate recognition when presented with (1) random sequences of 1–12 motifs (stereotyped song components) drawn from the training songs, and (2) 0.1–12-s excerpts of continuous song drawn from the training songs. We found that song recognition improved monotonically as more vocal material is provided. In the second experiment, we systematically substituted continuous, varying length regions of white noise for portions of the training songs and again examined recognition accuracy. Recognition remained above chance levels for all noise substitutions tested (up to 91% of the training stimulus) although all but the smallest substitutions led to some decrement in song recognition. Overall, above chance recognition could be obtained with surprisingly few motifs, short excerpts of song, and in the absence of large portions of the training songs. These results suggest that starlings acquire a representation of song during individual vocal recognition learning that is robust to perturbations and distributed broadly over large portions of these complex acoustic sequences.

The Protestant Reformation and Catholic Publishing: A Framework for Contemporary Understanding

Drawing from the perspective of an interdisciplinary exploration of the sociocultural impact of the printing press and its effects on Catholic thinkers, educators, and worship practices, the author of this article explores the educational mission of Catholic publishing during the Reformation and how it has evolved in modern times. First, the author discusses the communication dynamics of the Reformation and specifically the impact of the printing press. Second, the author explores the historical reasons for why the Roman Church perceived the need for uniformity in worship. Third, the author focuses on how the Roman Church built upon this framework of uniformity to define and shape the issues that were being discussed when expanding their outreach to the public during this period. Fourth, the author shows how Catholic worship and education evolved within an interpretation that is relevant to the educational mission of Catholic publishers today.     

II Spatial metaphors and somatic communication: the embodiment of multigenerational experiences of helplessness and futility in an obese patient

This paper explores the analysis of an obese woman who came to experience her flesh as a bodying forth of personal and multigenerational family and cultural experiences of helplessness. The paper discusses the ideas and images that formed the basis of how I engaged with these themes as they presented countertransferentially. My thesis is that clinical approaches which draw on spatial metaphors for the psyche offer valuable tools for working with people whose inner world expresses itself somatically because such metaphors can be used to engage simultaneously with the personal, cultural, and ancestral dimensions of these unconscious communications. The paper builds on Jung's view of the psyche as comprised of pockets of inner otherness (complexes), on Redfearn's image of psyche as landscape‐like and on Samuels’ thinking on embodied countertransference and on the political psyche. It also draws on Butler's work on the body as a social phenomenon and on the theme of being a helpless non‐person or nobody as explored in Tom Stoppard's play Rosencrantz and Guildenstern are Dead which retells Shakespeare's Hamlet from the perspective of two of the play's ‘bit’ characters.     

Strategie Calibration and Spatial Alignment: A Model From Prism Adaptation

Two types of adaptive processes involved in prism adaptation have been identified: slower spatial realignment among the several unique sensorimotor coordinate systems (spatial maps) and faster strategic motor control responses (including skill learning and calibration) to spatial misalignment. One measures the 1st process by assessing the aftereffects of prism exposure, whereas direct effects of the prism during exposure are a measure of the 2nd process. A model is described that relates those adaptive processes and distinguishes between extraordinary alignment and ordinary calibration. A conformal translation algorithm that operates on the hypothesized circuitry is proposed. The authors apply the model to explain the advantage of visual calibration when the limb is seen in the starting position prior to movement initiation. Implications of the model for the use of prism adaptation as a tool for investigation of motor control and learning are discussed.     

Monocular and Binocular Vision in the Control of Goal-Directed Movement

In the present research the authors examined the time course of binocular integration in goal-directed aiming and grasping. With liquid-crystal goggles, the authors manipulated vision independently to the right and left eyes of 10 students during movement preparation and movement execution. Contrary to earlier findings reported in catching experiments (I. Olivier, D. J. Weeks, K. L. Ricker, J. Lyons, & D. Elliott, 1998), neither a temporal nor a spatial binocular advantage was obtained in 1 grasping and 2 aiming studies. That result suggests that, at least in some circumstances, monocular vision is sufficient for the precise control of limb movements. In a final aiming experiment involving 3-dimen- sional spatial variability and no trial-to-trial visual feedback about performance, binocular vision was associated with greater spatial accuracy. Binocular superiority appeared to be most pronounced when participants were unable to adjust their limb control strategy or procedure on the basis of terminal feedback about performance.     

Prism Exposure Aftereffects and Direct Effects for Different Movement and Feedback Times

The effects of movement time and time to visual feedback (feedback time) on prism exposure aftereffects and direct effects were studied. In Experiment 1, the participants' (N = 60) pointing limb became visible early in the movement (.2-s feedback time, and eye-head aftereffects increased with increasing movement time (.5 to 3.0 s), but larger hand-head aftereffects showed little change. Direct effects (terminal error during exposure) showed near-perfect compensation for the prismatic displacement (11.4 diopters) when movement time was short but decreasing compensation with longer movement times. In Experiment 2, participants' (N = 48) eye-head aftereffects increased and their larger hand-head aftereffects decreased with increasing movement time (2.0 and 3.0 s), especially when feedback time increased (.25 and 1.5 s). Direct effects showed increasing overcompensation for longer movement and feedback times. Those results suggest that aftereffects and direct effects measure distinct adaptive processes, namely, spatial realignment and strategic control, respectively. Differences in movement and feedback times evoke different eye -hand coordination strategies and consequent direct effects. Realignment aftereffects also depend upon the coordination strategy deployed, but not all strategies support realignment. Moreover, realignment is transparent to strategic control and, when added to strategic correction, may produce nonadaptive performance.     

Learning Under Conditions of Action Information Feedback

Methodological and empirical issues in research on action information feedback (AIF) are discussed, with particular reference to the procedures and results of Annett (1970). Positioning responses practiced under conditions of AIF training are learned, though generally less well than under terminal IF conditions. Effects obtained as a result of AIF training may be subject to variations in movement extent required, gain and other transformations, frequency, temporal locus, and mode of augmentation, many aspects of which remain to be systematically studied.     

Dynamic Visual Acuity

Forty subjects took part in a one-handed catching task in which the period for which the mechanically projected tennis ball was illuminated in flight was varied systematically. Additionally, they were tested for (a) static visual acuity and (b) dynamic visual acuity, in which angular velocity was varied. As expected, both viewing period in the catching task and angular velocity in the acuity task were significant variables in performance. Correlation and principal-components analyses confirmed the findings of a previous experiment in that the correlated static visual acuity tasks were unrelated to both dynamic visual acuity (even when angular velocity was only 75°/sec) and catching performance. Further, dynamic acuity and catching were related under the majority of the combinations, and most frequently at the highest angular velocity, a fact which suggested that the dynamic element in both tasks is the common factor.
