Test anxiety and the hierarchical model of approach and avoidance achievement motivation

This research was designed to incorporate the test anxiety (TA) construct into the hierarchical model of approach and avoidance achievement motivation. Hypotheses regarding state and trait TA were tested in 2 studies, and the results provided strong support for the predictions. State TA (specifically, worry) was documented as a mediator of the negative relationship between performance-avoidance goals and exam performance. The positive relationship between performance-approach goals and exam performance was shown to be independent of TA processes. A series of analyses documented the conceptual and functional convergence of trait TA and fear of failure (FOF), and further validation of the proposed integration was obtained by testing trait TA/FOF and state TA together in the same model. Mastery goals were positively and performance-avoidance goals negatively related to long-term retention.     

Dynamics of 1:2 Coordination: Sources of Symmetry Breaking

Three asymmetries in the dynamics of 1:2 interlimb coordination were examined: the asymmetry in uncoupled frequencies, the asymmetry in coupled frequencies, and the left-right functional asymmetry of the body. In a bimanual 1:2 task, participants (N = 8) oscillated hand-held pendulums whose uncoupled frequencies were adjusted so that the first kind of asymmetry could be manipulated. For any given pendulum pair, the pendulum assuming the faster motion in the 1:2 coordination was oscillated in the right and the left hands. By assigning combinations of uncoupled eigenfrequencies and coupled task-specified frequencies across hands, the authors studied the interaction of all 3 asymmetries. The results confirm the appropriateness of generalized relative phase as a collective variable for 1:2 coordination. Additionally, they suggest that the generalized form of the detuning parameter represents the first asymmetry and that the coupling function expresses the second asymmetry. In 1:2 coordination, the body's functional asymmetry plays a limited role.     

Dynamics of 1:2 Coordination: Generalizing Relative Phase to n:m Rhythms

Interlimb rhythmic movements can be modeled as coupled oscillators, with stable performance characterized by the relative phase between the limbs. In the present study, that modeling strategy, verified previously for 1:1 coordination, was generalized to 1:2 coordination with a view to n:m coordination. The generalized model predicted interactions between coordination (specifically, 1:1 vs. 1:2) and the frequency asymmetry between the limbs determining mean relative phase and its variability. The predicted interactions were evaluated with bimanual 1:2 and 1:1 rhythmic tasks in which participants (N = 8) oscillated hand-held pendulums whose uncoupled frequencies could be adjusted so that different interlimb asymmetries were produced. The authors needed new analytic procedures to verify stable 1:2 coordination and to resolve stochastic and deterministic sources of variability in the component oscillations. The major expectations from the generalized model were confirmed, and the implications of additional but unpredicted findings for the modeling of multifrequency behavior are discussed.     

Paying for medical care: a Jewish view

According to Jewish law, there is a clear obligation to try to heal, and this duty devolves upon both the physician and the society. Jewish sources make it clear that health care is not only an individual and familial responsibility, but also a communal one. This social aspect of health care manifests itself in Jewish law in two ways: first, no community is complete until it has the personnel (and, one assumes, the facilities) to provide health care; second, the community must pay for the health care of those who cannot afford it as part of its provision for the poor. The community, in turn, must use its resources wisely, which is the moral basis within the Jewish tradition for some system of managed care. The community must balance its commitment to provide health care with the provision of other services.     

The influence of mastery‐avoidance goals on performance improvement

Two experiments focused on examining the influence of mastery‐avoidance goals on performance improvement, and more specifically, on mastery‐avoidance goals grounded in an intrapersonal standard. That is, herein, mastery‐avoidance goals entail striving to avoid doing worse than one has done before. Both experiments demonstrated that in a multiple‐trial context, mastery‐avoidance goals are deleterious for performance improvement relative to mastery‐approach, performance‐approach, and performance‐avoidance goals, and a no goal baseline. The findings were shown to be independent of participants' perceptions of goal difficulty, and were consistent not only across methodology but also across type of participant (undergraduates versus individuals in the workforce), and type and length of achievement task (a verbal skills task versus an ecologically valid managerial competencies exercise).

The Butterfly,the Mole and the Sage

Zhuangzi chooses a butterfly as a metaphor for transformation, a sighted creature whose inherent nature contains, and symbolizes, the potential for transformation from a less valued state to a more valued state. If transformation is not to be valued; if, according to a recent article by Jung Lee, ‘there is no implication that it is either possible or desirable for the living to awake from their dream’, why not tell a story of a mole awakening from a dream? This would be a more perfect story. There would be no point of a mole awakening since (setting aside tactile, olfactory, auditory and taste sensations for the purpose of the example), there is no way to distinguish between the world of the mole's imagination and the real world that is forever unavailable to a mole. In addition, Zhuangzi relates the story of the coming of a great sage in which it is clearly stated that ‘Only at the ultimate awakening shall we know that this is the ultimate dream’. Such textual evidence both from the choice of metaphors and evidential passages indicates that the message of the Zhuangzi is not epistemological relativity, but one of transformation from a state of intellectual blindness to a state of true understanding.     

Color and psychological functioning: the effect of red on performance attainment

This research focuses on the relation between color and psychological functioning, specifically, that between red and performance attainment. Red is hypothesized to impair performance on achievement tasks, because red is associated with the danger of failure in achievement contexts and evokes avoidance motivation. Four experiments demonstrate that the brief perception of red prior to an important test (e.g., an IQ test) impairs performance, and this effect appears to take place outside of participants' conscious awareness. Two further experiments establish the link between red and avoidance motivation as indicated by behavioral (i.e., task choice) and psychophysiological (i.e., cortical activation) measures. The findings suggest that care must be taken in how red is used in achievement contexts and illustrate how color can act as a subtle environmental cue that has important influences on behavior.     

Effects of response priming and inhibition on movement planning and execution

The authors used a precueing method to examine the effects of response priming and inhibition on goal-directed action. Participants (N = 18) completed aiming movements to 1 of 2 locations following predictive (80% cued), nonpredictive (50% cued), and antipredictive (20% cued) precues at 1 of the 2 possible target locations. Consistent with previous research, participants responded more quickly to targets at cued locations than to targets at uncued locations in the 80% condition, and more quickly to targets presented at the uncued than to those presented at cued locations in the 50% and 20% conditions. As predicted by models of action-centered selective attention, movement trajectories deviated away from the cued location in the 50% condition. Movement trajectories were also altered in the 80% and the 20% conditions. Movements directed to the uncued location deviated away from the cued location in the 80% condition, whereas movements directed to the cued location deviated away from the uncued location in the 20% condition. The authors explain the latter trajectory results as a strategy of overcompensation.
