Mood, personality, and self-monitoring: negative affect and emotionality in relation to frontal lobe mechanisms of error monitoring

A fundamental question in frontal lobe function is how motivational and emotional parameters of behavior apply to executive processes. Recent advances in mood and personality research and the technology and methodology of brain research provide opportunities to address this question empirically. Using event-related-potentials to track error monitoring in real time, the authors demonstrated that variability in the amplitude of the error-related negativity (ERN) is dependent on mood and personality variables. College students who are high on negative affect (NA) and negative emotionality (NEM) displayed larger ERN amplitudes early in the experiment than participants who are low on these dimensions. As the high-NA and -NEM participants disengaged from the task, the amplitude of the ERN decreased. These results reveal that affective distress and associated behavioral patterns are closely related with frontal lobe executive functions.     

Variables Influencing the Perceived Relationship Between Performance and Pay in a Merit Pay Environment

The purpose of the study is to gain a better understanding of the pay-for-performance perception. Such a knowledge may allow for improvement in the effectiveness of incentive compensation plans. Sample comprises 406 employees whose salary changes were conditioned by a merit pay plan. Results suggest that pay-for-performance perception is related to the actual pay-for-performance link, their trust in decision-makers, their procedural justice perception, the size of their outcomes—that is, pay increase and performance rating—and their satisfaction with these outcomes.     

Reactions of would-be helpers whose offer of help is spurned

An experiment was conducted to test the proposition that rejection of help by a needy recipient constitutes a negative expectancy violation for the would-be helper. The helper will react to this self-threat by expressing negative affect, unfavorable evaluations of the recipient, low attraction to the recipient, and causal attributions for the rejection that cast the recipient in an unflattering light. To test these hypotheses, college freshmen were prompted to offer rules for word construction to a same-sex recipient (a confederate) who was described as needing remediation on vocabulary and who "failed" a practice task. After rejecting/accepting the help, the recipient failed or succeeded on a comparable task. The results were consistent with these predictions. Dispositionally high expectations of interpersonal success served to amplify helpers' reactions to rejection/acceptance.     

Pitch of infant crying and caregiver responses in a natural setting

The naturally occurring cries of 13 infants in a day-care center were tape-recorded and spectrum-analyzed for the peak fundamental frequency. Caregivers' responses to higher-pitched cries were rated by observers as more urgent, and they more frequently included additional attempts to soothe the infant. These results provide some of the first ecologically valid evidence that the pitch of infant crying is related to the urgency and nature of caregivers' responses.     

Individual differences in the vibrotactile perception of a “simple” pattern set

Discriminative capacities for vibrotactile spatiotemporal patterns were examined in 62 college students with three tasks: identification, masking, and discrimination of the letters “X” and “O” presented tactually on the Optacon, a reading machine for blind persons. Individual differences in performance and interrelations among scores within and across paradigms were explored. In identification, most persons quickly achieved consistently better than 90% performance, but others failed to identify the patterns above 80%, even after prolonged training. The same performance variance was found when the task was repeated by 23 Naval student pilots. Masking and discrimination measured susceptibility to interference when patterns followed one another closely in time. The resulting functions were typical, with poorest performance at short stimulus onset asynchronies. Again, a wide range of performance was seen. Individual performance, however, appeared to be consistent across tasks, suggesting that abilities in a variety of pattern-perception tasks might be predictable.
