A camera-based scoring system for evaluating performance accuracy during a golf putting task

Golf putting accuracy is often evaluated by measuring the distance that the ball finishes from the hole. However, accuracy is a function of line and length, and distance-from-hole measures confound these two factors. A scoring system for evaluating putting accuracy is described that enables the efficient measurement of errors in line and length. A camera placed above the hole takes digital photographs of the final position of the ball. A custom-developed program written in the National Instruments LabVIEW graphical programming language derives a variety of accuracy measures from these photographs, including distance from the hole, angle of error, distance short or long from the hole, and distance left or right from the hole. Evaluation of the system indicated that the measures were as accurate as manual measurements and were reliable when rescored on separate occasions. The camera-based scoring system presents a number of advantages in the evaluation of putting accuracy and may be extended to examine performance in other sports.

Movement direction or change in distance? Self- and object-related approach-avoidance motions

Based on the conceptualization of approach as a decrease in distance and avoidance as an increase in distance, we predicted that stimuli with positive valence facilitate behavior for either approaching the stimulus (object as reference point) or for bringing the stimulus closer (self as reference point) and that stimuli with negative valence facilitate behavior for withdrawing from the stimulus or for pushing the stimulus away. In Study 1, we found that motions to and from a computer screen where positive and negative words were presented lead to compatibility effects indicative of an object-related frame of reference. In Study 2, we replicated this finding using social stimuli with different evaluative associations (young vs. old persons). Finally, we present evidence that self vs. object reference points can be induced through instruction and thus lead to opposite compatibility effects even when participants make the same objective motion (Study 3).     

Withholding Effort in Organizations: Toward Development and Validation of a Measure

Field research into the topic of withholding effort and its variants (shirking, loafing, free riding, and job neglect) has been limited due to a lack of measures that are applicable to organizational settings. This study used a multi-phase process to ascertain a measure of withholding effort that can be used in organizational settings. Items were generated through literature review and discussions with practitioners; culled by the authors; and tested in a field study in multiple, diverse organizations. Exploratory and confirmatory factor analyses found the construct of withholding effort to be multidimensional, but not necessarily as previous theoretical work in the area would suggest. Correlations of the various dimensions of withholding effort scales with existing scales tapping a wide range of employee attitudes were consistent with a priori expectations. Implications for the use of these scales in future workplace research and their practical application in organizations are discussed.     

The presence of the past: using memory work to search for psychological traces of the Nazi past in contemporary Germans

This study examines how far traces of the Nazi past can still be found in the psychological family environment of college students and academics attending a counselling centre two generations after the end of World War II. It considers how such traces can be elicited in discussions and tackled systematically within a therapeutic context. It was found that many families had never talked about their memories of the Nazi period, ignoring or repressing them. This study showed that the failure to discuss such topics within families was of decisive significance during counselling sessions, and that current problems often relate to an unprocessed family past.     

The development of an attentional bias for angry faces following Pavlovian fear conditioning

Although it is well documented that fear responses develop following aversive Pavlovian conditioning, it is unclear whether fear learning also manifests in the form of attentional biases for fear-related stimuli. Boschen, Parker, and Neumann (Boschen, M. J., Parker, I., & Neumann, D. L. (2007). Changes in implicit associations do not occur simultaneously to Pavlovian conditioning of physiological anxiety responses. Journal of Anxiety Disorders, 21, 788-803.) showed that despite the acquisition of differential skin conductance conditioned responses to angry faces paired (CS+) and unpaired (CS−) with an aversive shock, development of implicit associations was not subsequently observed on the Implicit Association Test. In the present study, participants (N = 76) were assigned either to a Shock or NoShock group and completed a similar aversive Pavlovian conditioning procedure with angry face CS+ and CS− stimuli. Participants next completed a visual probe task in which the angry face CS+ and CS− stimuli were paired with angry face control stimuli and neutral faces. Results confirmed that differential fear conditioning was observed in the Shock group but not in the NoShock group, and that the Shock group subsequently showed a selective attentional bias for the angry face CS+ compared with the CS− and control stimuli during the visual probe task. The findings confirm the interplay between learning-based mechanisms and cognitive processes, such as attentional biases, in models of fear acquisition and have implications for treatment of the anxiety disorders.     

When the method makes a difference: Antagonistic effects on “automatic evaluations” as a function of task characteristics of the measure

Researchers often employ implicit measures as dependent variables to investigate processes of attitude formation and change. In such studies, experimentally induced differences are typically interpreted as reflecting change in automatic evaluations. We argue that experimentally induced effects on implicit measures may not always reflect genuine changes in evaluative responses, but can be driven by the mechanisms underlying the measurement procedure. In line with this assumption, the present research shows that these mechanisms can produce opposite effects of the same experimental manipulation for otherwise equivalent implicit measures. These results indicate that merely observing experimental effects on implicit measures does not allow direct inferences regarding changes in automatic evaluations. Instead, psychological interpretations of such effects hinge upon the mechanics of how a given measurement procedure responds to variations in the context. Implications for research using implicit measures are discussed.     

A Euthyphronic Problem for Kitcher's Epistemology of Science

Philip Kitcher has advanced an epistemology of science that purports to be naturalistic. For Kitcher, this entails that his epistemology of science must explain the correctness of belief-regulating norms while endorsing a realist notion of truth. This paper concerns whether or not Kitcher's epistemology of science is naturalistic on these terms. I find that it is not but that by supplementing the account we can secure its naturalistic standing.     

Emotions in Go/NoGo conflicts

On the basis of current emotion theories and functional and neurophysiological ties between the processing of conflicts and errors on the one hand and errors and emotions on the other hand we predicted that conflicts between prepotent Go responses and occasional NoGo trials in the Go/NoGo task would induce emotions. Skin conductance responses (SCRs), corrugator muscle activity, and startle blink responses were measured in three experiments requiring speeded Go responses intermixed with NoGo trials of different relative probability and in a choice reaction experiment serving as a control. NoGo trials affected several of these emotion-sensitive indicators as SCRs and startle blinks were reduced whereas corrugator activity was prolonged as compared to Go trials. From the pattern of findings we suggest that NoGo conflicts are not aversive. Instead, they appear to be appraised as obstructive for the response goal and as less action relevant than Go trials.
