Zajonc's Cockroach Study on Drive Theory
To empirically test his drive theory of social facilitation and inhibition, Robert Zajonc conducted a study using cockroaches. He hypothesized that the presence of other cockroaches would improve performance on a simple task but impair performance on a difficult one. Cockroaches were placed in either a simple straight runway or a complex cross-shaped maze, both while alone and in the presence of an audience of other cockroaches. The results showed that cockroaches completed the simple runway faster with an audience, but completed the complex maze slower when watched, confirming Zajonc's hypothesis and providing support for his drive theory.

Social Facilitation
According to Zajonc's drive theory, how does the physiological arousal triggered by an audience affect an individual's performance?
According to Zajonc's drive theory, arrange the following steps in the correct causal order to explain how social presence influences task performance.
A researcher is observing participants as they attempt to solve a complex, unfamiliar logic puzzle for the first time. Based on Zajonc’s Drive Theory, the researcher should expect these participants to solve the puzzle more accurately when being observed than when working alone.
Zajonc's drive theory explains human performance by connecting social presence to internal mechanisms. Match each theoretical component with its specific functional role in this explanatory system.
Zajonc's Drive Theory explains the effects of an audience by proposing a causal chain. Which of the following best describes the role of 'physiological arousal' in this chain?
According to Zajonc's drive theory, the state of physiological arousal triggered by an audience increases the probability that an individual will perform their _____ response.
If a researcher finds that the presence of an audience significantly improves the performance of a beginner on a complex and unfamiliar task, this specific result would be evaluated as _____ with the core predictions of Zajonc's Drive Theory.
Learn After
In Robert Zajonc's study on social facilitation using cockroaches, what was the observed effect of an audience on the subjects' performance in a complex maze?
Based on the findings of Robert Zajonc's cockroach experiment, arrange the following experimental conditions in order from the expected fastest completion time (1) to the expected slowest completion time (4).
In Robert Zajonc's cockroach experiment, if the audience had improved completion times for both the simple runway and the complex maze, this result would have refuted his hypothesis concerning social inhibition.
In Robert Zajonc's study of social facilitation using cockroaches, which apparatus was specifically designed to represent the 'simple task' condition?
According to the results of Robert Zajonc's cockroach study, the presence of an audience has a consistently beneficial effect on performance regardless of the difficulty of the task.
In Zajonc's (1969) cockroach study on drive theory, match each condition or finding with its correct description.
In Robert Zajonc's cockroach study, the finding that an audience slowed cockroach completion times in the complex cross-shaped maze is the empirical evidence that _____ his hypothesis that social presence impairs performance on difficult tasks.
