Giving and Receiving Awards

ABSTRACT— Awards in the form of orders, medals, decorations, prizes, and titles are ubiquitous in monarchies and republics, private organizations, and not-for-profit and profit-oriented firms. Nevertheless, this kind of nonmaterial extrinsic incentive has been given little attention in the social sciences, including psychology. The demand for awards relies on an individual's desire for distinction, and the supply of awards is governed by the desire to motivate. The technique of analytic narratives is used to show that a number of empirically testable propositions about awards are consistent with observable data.     

Tau and Kappa Effects: The Case of Space-Like-Extent Frequencies

The organization of tonal-temporal information in a memory task was studied in two experiments. The stimuli consisted of four different configurations of eight beeps, presented sequentially. In two configurations, the stimuli were tonal-time congruent, with (constant or variable) inter-stimulus tonal distances corresponding to (constant or variable) inter-stimulus time intervals. In the two other configurations, the stimuli were tonal-time incongruent, with (constant or variable) inter-stimulus tonal distances not corresponding to (variable or constant) inter-stimulus time intervals. After a learning phase consisting of 20 presentations of the target configuration, participants reproduced the spatial (Experiment 1) or temporal (Experiment 2) characteristics of the target 60 times in succession without ever re-examining the target configuration. Classically, in incongruent space-time conditions, the effects of variable inter-stimulus time intervals or inter-stimulus space intervals on the reproduction of constant distances (Tau effect) and constant durations (Kappa effect), respectively, are observed. However, our results showed that this was not the case when the spatial dimension was substituted for the tonal dimension (i.e., the distances between consecutive tones). The results are discussed in the light of the properties of the physical versus frequential space, that is, of a tonal dimension in which the different frequencies were considered as the spatial dimension.     

A Dialectic on Validity: Where We Have Been and Where We Are Going

It has been suggested that the primary issue in considerations of validity today is the discrepancy between currently accepted theory and the practice of validation. The reason for this discrepancy may be that although considerable discussion has taken place in educational measurement and psychometrics regarding changes in our conceptions of validity, that has not been the case more generally in the social and behavioral sciences. A dialectic on the current status of validity theory for social and behavioral scientists is presented to help bridge this gap.     

Synchronization with competing visual and auditory rhythms: bouncing ball meets metronome

Synchronization of finger taps with periodically flashing visual stimuli is known to be much more variable than synchronization with an auditory metronome. When one of these rhythms is the synchronization target and the other serves as a distracter at various temporal offsets, strong auditory dominance is observed. However, it has recently been shown that visuomotor synchronization improves substantially with moving stimuli such as a continuously bouncing ball. The present study pitted a bouncing ball against an auditory metronome in a target–distracter synchronization paradigm, with the participants being auditory experts (musicians) and visual experts (video gamers and ball players). Synchronization was still less variable with auditory than with visual target stimuli in both groups. For musicians, auditory stimuli tended to be more distracting than visual stimuli, whereas the opposite was the case for the visual experts. Overall, there was no main effect of distracter modality. Thus, a distracting spatiotemporal visual rhythm can be as effective as a distracting auditory rhythm in its capacity to perturb synchronous movement, but its effectiveness also depends on modality-specific expertise.     

Distinctive features,dichotic competition,and the encoding of stop consonants

“Same”-“different” response latencies were measured for dichotic CV syllables at stimulus onset asynchronies (SOAs) of 20–480 msec. The results showed a consistent effect of distinctive feature separation on latencies and error rates, which persisted at longer SOAs. This supports the idea that phonemes are retained in memory in a distinctive feature code at least for half a second, and that such a code is also involved in the comparison of successive phonemes. The pattern of errors and latencies suggested two components in dichotic competition: “perceptual integration” at short SOAs and “perceptual noise” at longer SOAs. A “perceptual space” analogy is suggested: two stimuli must be separated by a minimum distance (including time separation as a dimension) to be perceived as distinct; if they are perceived as distinct, they are first categorized and then compared by assessing their distance in a phonetic space.     

Cross-modality matching of muscular tension to loudness

In a single session, Ss produced and estimated a series of electromyographically measured tensions, estimated the loudness of pure tones, and then matched muscular tension to tonal loudness. In all cases, power functions adequately represented the estimation and matching data. For two Ss, who scaled tension in the abductor of the little finger, the slopes of the estimation functions successfully predicted the slopes of the matching functions. For the other Ss the prediction from estimation to matching data was fair, but not good; these Ss scaled adductor tension, for which the electromyographic measurements were methodologically questionable. The data suggest that a consistent scale of muscular tension can be constructed, and that the scale can be validated by crossmodal comparison.     

Learning and production of movement sequences: behavioral, neurophysiological, and modeling perspectives

A wave of recent behavioral studies has generated a new wealth of parametric observations about serial order behavior. What was a trickle of neurophysiological studies has grown to a steady stream of probes of neural sites and mechanisms underlying sequential behavior. Moreover, simulation models of serial behavior generation have begun to open a channel to link cellular dynamics with cognitive and behavioral dynamics. Here we review major results from prominent sequence learning and performance tasks, namely immediate serial recall, typing, 2 x N, discrete sequence production, and serial reaction time. These tasks populate a continuum from higher to lower degrees of internal control of sequential organization and probe important contemporary issues such as the nature of working-memory representations for sequential behavior, and the development and role of chunks in hierarchical control. The main movement classes reviewed are speech and keypressing, both involving small amplitude movements amenable to parametric study. A synopsis of serial order models, vis-a-vis major empirical findings leads to a focus on competitive queuing (CQ) models. Recently, the many behavioral predictive successes of CQ models have been complemented by successful prediction of distinctively patterned electrophysiological recordings. In lateral prefrontal cortex, parallel activation dynamics of multiple neural ensembles strikingly matches the parallel dynamics predicted by CQ theory. An extended CQ simulation model--the N-STREAMS neural network model--exemplifies ongoing attempts to accommodate a broad range of both behavioral and neurobiological data within a CQ-consistent theory.
