Collectivistic orientation, which entails interdependent self-construal and concern for interpersonal harmony and social adjustment, has been suggested to be associated with detecting emotional expressions that signal social threat than individualistic orientation, which entails independent self-construal. The present research tested if this detection is a result of enhanced perceptual sensitivity or of response bias. We used country as proxy of individualism and collectivism (Country IC), measured IC of individuals with a questionnaire (Individual IC) and manipulated IC with culture priming (Situational IC). Dutch participants in the Netherlands (n = 143) and Chinese participants in China (n = 151) performed a social threat detection task where they had to categorize ambiguous facial expressions as “angry” or “not angry”. As the stimuli varied in degrees of scowling and frequency of presentation, we were able to measure the participants' perceptual sensitivity and response bias following the principles of the Signal Detection Theory. On the Country IC level, the results indicated that individualism-representative Dutch participants had higher perceptual sensitivity than collectivism-representative Chinese participants; whereas, Chinese participants were more biased towards categorizing a scowling face as “angry” than the Dutch (i.e. stronger liberal bias). In both groups, collectivism on the Individual IC was associated with a bias towards recognizing a scowling face as “not angry” (i.e. stronger conservative bias). Culture priming (Situational IC) affected neither perceptual sensitivity nor response bias. Our data suggested that cultural differences were in the form of behavioral tendency and IC entails multiple constructs linked to different outcomes in social threat detection.

Using the five‐factor personality model, the present study explored the influence of personality factors on sustained attention and perceived workload. Ninety‐six college‐aged participants were administered a 12 minute vigilance fast event rate task. Following the vigil, participants were asked to first, rate their perceived workload of the task using the NASA‐TLX, and then second, complete the NEO‐PI‐R personality inventory. Traditional measures of hits, false alarms, and reaction times were examined as well as the signal detection indices of perceptual sensitivity and response bias. Extraversion correlated with false alarms (r = 0.181; eta2 = 0.055) and conscientiousness correlated with both false alarms (r = −0.275, eta2 = 0.097) and perceptual sensitivity (r = 0.227, eta2 = 0.052). With regard to perceived workload, neuroticism was related to perceived frustration (r = 0.238, eta2 = 0.057). The findings are discussed in terms of theoretical implications, impact of task parameters, and practical applications. Copyright © 2002 John Wiley & Sons, Ltd.
