Manifest anxiety and two-point threshold sensitivity.

The present study utilized 27 college students (14 females, 13 males) to investigate the effects of anxiety upon the ability to attend to detail (two-point threshold sensitivity). It was hypothesized that subjects both low and high in anxiety would have a smaller threshold than mild or moderately anxious subjects. A curvilinear correlation of .83 (p less .01) was obtained between anxiety scores and two-point threshold sensitivity. There was no significant difference between mean thresholds for those scoring above or below the median on the anxiety scale. Suggestions for further research are discussed.     

Effects of anxiety on inferential reasoning task performance

Three experiments were conducted in which high anxiety and low anxiety subjects were required to construct inferences. In Experiment 1 there was no anxiety-related performance deficit when inferring a necessary anaphoric relation, a process argued to be automatic. Experiments 2 and 3 involved the verification of unnecessary inferences, a process argued to involve the utilization of the working memory system. In both Experiments 2 and 3 there was an anxiety-related performance deficit. The results are consistent with a working memory-oriented account of anxiety-related performance effects, as deficits were restricted to capacity-demanding tasks.     

Multidimensional influences of anxiety and assessment type on task performance

We examined state evaluation anxiety, trait evaluation anxiety, and neuroticism in relation to New Zealand first-year university students’ (n = 234) task performance on either a...     

State anxiety, performance accuracy, and work pace in a simulated pharmacy dispensing task

This study examined the effects of scores on state anxiety on overall accuracy of performance and speed of working in a simulated pharmacy dispensing task. 75 undergraduates worked in a simulated pharmacy environment, designed by Schell and Grasha in 1998, to fill 42 mock orders for simulated pharmacy items. Participants' accuracy and work pace in the simulation, presimulation stress, and postsimulation perceived workload and state anxiety were measured. Analysis indicated that state anxiety and overall accuracy were strongly related. State anxiety appears to be one of the best predictors of errors in the simulated pharmacy dispensing task found so far, while the lack of relationship between work pace and accuracy was confirmed. Work pace predicted accuracy, indirectly, but only after statistically removing the effects of anxiety, task frustration, significant-other stress, and grade point average.     

Manifest anxiety and fearfulness in children and adolescents.

The relationship between self-reported fear and anxiety was examined in a large sample of normal Australian children and adolescents. Participants completed the Fear Survey Schedule for Children--Revised (Ollendick, 1983) and the Revised Children's Manifest Anxiety Scale (Reynolds & Richmond, 1978). Following an examination of the internal consistency of these instruments, correlational analyses were conducted on anxiety and fear scores. Fear scores were shown to be sensitive to anxiety, sex, and age groups. Furthermore, discriminant analysis showed that high-anxiety children indicated a greater fear of items related to failure and criticism than did low-anxiety children. Other issues, including the content overlap between the two scales used in the investigation, are discussed.
