Manifest Anxiety

Female college students were selected on the basis of their scores on the Manifest Anxiety Scale. The subjects worked either alone or in pairs on a multiple-solution anagrams task. The experiment had a 2 × 2 × 2 design, with group type (nominal versus real), manifest anxiety (low versus high), and induced stress (low versus high) as the three variables. The results indicated that increased anxiety and stress were relatively more detrimental to the performance of real groups as compared with nominal groups.

The Individual

Social loafing has been defined as a phenomenon in which people exhibit a sizable decrease in individual effort when performing in groups as compared to when they perform alone, and has been regarded as a state variable. In this study, we instead conceptualized social loafing as a habitual response, given that many people have been found to be susceptible to social loafing in group tasks. We developed the self-reported Social Loafing Tendency Questionnaire (SLTQ) to measure individual variations in social loafing. In Study 1, the reliability and validity of the SLTQ were established in a sample of college students. In Study 2, SLTQ scores significantly negatively predicted individual performance in the group task condition, but not in the individual task condition. Social loafing can also be considered a trait variable, as it was found to modulate group dynamics when it was activated in a typical situation (i.e., being in a group).

Task Conditions

Purpose Prior investigations suggest that simultaneous performance of more than 1 motor-oriented task may exacerbate speech motor deficits in individuals with Parkinson disease (PD). The purpose of the current investigation was to examine the extent to which performing a low-demand manual task affected the connected speech in individuals with and without PD. Method Individuals with PD and neurologically healthy controls performed speech tasks (reading and extemporaneous speech tasks) and an oscillatory manual task (a counterclockwise circle-drawing task) in isolation (single-task condition) and concurrently (dual-task condition). Results Relative to speech task performance, no changes in speech acoustics were observed for either group when the low-demand motor task was performed with the concurrent reading tasks. Speakers with PD exhibited a significant decrease in pause duration between the single-task (speech only) and dual-task conditions for the extemporaneous speech task, whereas control participants did not exhibit changes in any speech production variable between the single- and dual-task conditions. Conclusions Overall, there were little to no changes in speech production when a low-demand oscillatory motor task was performed with concurrent reading. For the extemporaneous task, however, individuals with PD exhibited significant changes when the speech and manual tasks were performed concurrently, a pattern that was not observed for control speakers.
