Aging and the inhibition of competing hypotheses during visual word identification: evidence from the progressive demasking task.

Two experiments used the progressive demasking (PD) task to examine age differences in the ability to inhibit higher frequency competitors during the process of identifying a visually degraded word. In Experiment 1, older adults exhibited a larger inhibitory neighborhood frequency effect (i.e., slower identification of words with many higher frequency competitors) than younger adults, but additional analyses indicated that this difference could be explained by general slowing rather than a deficit in inhibitory abilities. In Experiment 2, a primed version of the PD task was used to promote hypothesis testing by semantically priming the target word (e.g., cry-weep) or a higher frequency competitor of the target (e.g, day-weep) prior to the onset of the demasking sequence. Although older adults were more likely to make identification errors consistent with an inhibitory deficit (e.g., identifying weep as week), these errors were infrequent overall and there was no corresponding evidence of a larger interference effect in the older adults' identification latencies. Taken together, performance in these two tasks provides little evidence of reduced inhibitory functioning in older adults. The implications for the inhibitory deficit hypothesis of cognitive aging and directions for future are discussed.

Using frame-of-reference training to understand the implications of rater idiosyncrasy for rating accuracy.

Frame-of-reference (FOR) rater training is one technique used to impart a theory of work performance to raters. In this study, the authors explored how raters' implicit performance theories may differ from a normative performance theory taught during training. The authors examined how raters' level and type of idiosyncrasy predicts their rating accuracy and found that rater idiosyncrasy negatively predicts rating accuracy. Moreover, although FOR training may improve rating accuracy even for trainees with lower performance theory idiosyncrasy, it may be more effective in improving errors of omission than commission. The discussion focuses on the roles of idiosyncrasy in FOR training and the implications of this research for future FOR research and practice.

Presentation modality and indirect performance information: effects on ratings, reactions, and memory.

The authors investigated whether raters integrate indirect (second-hand) information from an employee's co-worker with their direct observations when completing performance evaluations. Performance levels of direct and indirect information and presentation modality (auditory vs. textual) were manipulated (N = 220). Results showed that indirect information was perceived to be of highest utility when the performance levels of the direct and indirect information were consistent. Confidence in performance ratings was lowest when the indirect source delivered negative performance feedback that was contrary to the rater's own positive observations. Indirect information was only reflected in the performance ratings when direct observations were positive. There was a significant 3-way interaction between performance level of the direct information, performance level of the indirect information, and presentation modality on memory for performance incidents.
