On the detection of a brief signal in the temporal center of a noise masker of varying duration

The threshold of a brief signal temporally centered in a noise masker first increases and then decreases as the masker is increased in duration. We discuss two explanations for this “over-shoot” phenomenon which consider the role of peaks of an exponentially weighted sliding integrator. One such explanation takes into account the finding that the steepness of the psychometric function continues to increase monotonically as its location moves first right and then left.     

Self-esteem,need gratification,and work satisfaction: A test of competing explanations from consistency theory and self-enhancement theory

A sample of 112 administrators provided self-report data used to test two hypotheses derived from Korman's consistency model of work behavior. As predicted, those with high self-esteem experienced significantly greater need gratification than did those with low self-esteem, and self-esteem also significantly positively moderated the relationship between n gratification and work satisfaction. Need gratification was assessed for only those needs that were most salient for each person, thus eliminating a rival interpretation of the findings derived from the self-enhancement model of self-esteem. The moderating effect of self-esteem on the n gratification-work satisfaction relationship was limited to those experiencing low levels of n gratification, indicating a possible “boundary condition” of consistency theory. A problem with the use of moderator variables in behavioral science was also discussed.     

Adolescent Smoking Behavior and the Recognition of Cigarette Advertisements1

In a study designed to assess the relationship between smoking status and correct identification of cigarette brands, junior high school students from two schools viewed cigarette and automobile advertisements with brand and model identification deleted. Results showed that adolescents with higher ad recognition scores were more likely to smoke cigarettes. In addition, a relationship was found between age and correct identification of cigarette advertisements, with older students identifying more ads correctly than younger students. No significant effects emerged for identification of automobile advertisements except for sex, with boys identifying more advertisements than girls. Additional findings indicated that even “experimental” smokers, who smoked as little as once per year, recognized significantly more cigarette advertisements than nonsmokers. These and other results are discussed in terms of their implications for prevention and policy issues. It is argued that society's allowance of printed cigarette advertising overlooks adolescents' heightened vulnerability to the kinds of appeals used in cigarette advertisements. Present policy also overlooks adolescents' relative unresponsiveness to the health risk information required in cigarette advertisements.     

Prevocational Experience and Postentry Behavior: Occupational Influences on Job Attitudes and Turnover

The effect of prevocational contact on postentry behavior was studied using a sample of staff nurses. The results indicated that those nurses who had prevocational contact with the nursing occupation had different conceptions of the nursing role and more positive work attitudes than those who did not have prevocational contact with the profession. The groups. however, did not differ with respect to turnover.     

Self-respect and pro-relationship behavior in marital relationships

This work advances an interdependence theoretic analysis of the role of self-respect in ongoing close relationships. Self-respect is defined as the tendency to perceive the self as a principled person who is worthy of honor and high regard and is argued to rest on moral integrity. Consistent with predictions, results from a study of marital relationships revealed that individual self-respect is positively associated with both the individual's and the partner's pro-relationship behavior (accommodation, forgiveness, conciliation). Mediation analyses revealed that self-respect not only exhibits direct associations with each person's behavior, but also exhibits indirect associations with each person's behavior, via the impact of each person's actions on reciprocal pro-relationship behavior from the partner. Mediation was more reliably observed for the association of self-respect with partner behavior than for the association with individual behavior. Both individual pro-relationship behavior and partner pro-relationship behavior are positively associated with couple well-being, which in turn is positively associated with personal well-being (life satisfaction, physical health, psychological adjustment). These associations were evident in both within-participant and across-partner analyses and for both self-report and interaction-based measures of behavior. Self-respect reliably accounts for unique variance beyond variance attributable to self-esteem.     

Dealing with betrayal in close relationships: does commitment promote forgiveness?

This work complements existing research regarding the forgiveness process by highlighting the role of commitment in motivating forgiveness. On the basis of an interdependence-theoretic analysis, the authors suggest that (a) victims' self-oriented reactions to betrayal are antithetical to forgiveness, favoring impulses such as grudge and vengeance, and (b) forgiveness rests on prorelationship motivation, one cause of which is strong commitment. A priming experiment, a cross-sectional survey study, and an interaction record study revealed evidence of associations (or causal effects) of commitment with forgiveness. The commitment-forgiveness association appeared to rest on intent to persist rather than long-term orientation or psychological attachment. In addition, the commitment-forgiveness association was mediated by cognitive interpretations of betrayal incidents; evidence for mediation by emotional reactions was inconsistent.     

Relative damping improves linear mass-spring models of goal-directed movements

A limitation of a simple linear mass-spring model in describing goal directed movements is that it generates rather slow movements when the parameters are kept within a realistic range. Does this imply that the control of fast movements cannot be approximated by a linear system? In servo-control theory, it has been proposed that an optimal controller should control movement velocity in addition to position. Instead of explicitly controlling the velocity, we propose to modify a simple linear mass-spring model. We replaced the damping relative to the environment (absolute damping) with damping with respect to the velocity of the equilibrium point (relative damping). This gives the limb a tendency to move as fast as the equilibrium point. We show that such extremely simple models can generate rapid single-joint movements. The resulting maximal movement velocities were almost equal to those of the equilibrium point, which provides a simple mechanism for the control of movement speed. We further show that peculiar experimental results, such as an 'N-shaped' equilibrium trajectory and the difficulties to measure damping in dynamic conditions, may result from fitting a model with absolute damping where one with relative damping would be more appropriate. Finally, we show that the model with relative damping can be used to model subtle differences between multi-joint interceptions. The model with relative damping fits the data much better than a version of the model with absolute damping.     

Straightness as a cue for luminance edge interpretation

In order to determine the reflectance of a surface, it is necessary to discount luminance changes produced by illumination variation, a process that requires the visual system to respond differently to luminance changes that are due to illumination and reflectance. It is known that various cues can be used in this process. By measuring the strength of lightness illusions, we find evidence that straightness is, used as a cue: When a boundary is straight rather than curved, it has a greater tendency to be discounted, as if it were an illumination edge. The strongest illusions occur when a boundary has high contrast and has multiple X-junctions that preserve a consistent contrast ratio.     

Too proud to let go: narcissistic entitlement as a barrier to forgiveness

Narcissistic entitlement impedes forgiveness in ways not captured by other robust predictors (e.g., offense severity, apology, relationship closeness, religiosity, Big Five personality factors), as demonstrated in 6 studies. Narcissistic entitlement involves expectations of special treatment and preoccupation with defending one's rights. In Study 1, entitlement predicted less forgiveness and greater insistence on repayment for a past offense. Complementary results emerged from Study 2, which used hypothetical transgressions, and Study 3, which assessed broad forgiveness dispositions. Study 4 examined associations with the Big Five, and Study 5 extended the findings to a laboratory context. Study 6 demonstrated that entitlement predicted diminished increases in forgiveness over time. Taken together, these results suggest that narcissistic entitlement is a robust, distinct predictor of unforgiveness.
