“…To our knowledge no celebrity doppelganger tests have yet been published, though at least one is in development (Meschke et al, 2018). This other doppelganger test differs from the FFDT in several important ways, including presenting uncropped images with nonfacial information, using only noncelebrity images as lures, and asking participants to identify the celebrity in each pair of images (rather than specifying the name of the celebrity to select).…”

Face recognition assessments that use images of celebrities require not only face recognition ability but also pop-culture knowledge and successful recall of identifying information. Here, we introduce a task designed to measure face recognition more specifically: the Famous Faces Doppelgangers Test (FFDT). Participants ( N = 57,407) identified 40 celebrities paired with lookalike doppelgangers, allowing face recognition ability to be assessed without requiring information recall. In addition, participants reported whether they were familiar with each celebrity, allowing poor face recognition ability to be differentiated from low pop-culture knowledge. FFDT performance was reliable ( rxx = .80), similar across participants of different racial and ethnic groups, and more highly correlated with memory for faces ( r = .50) and self-reported face recognition ability ( r = .48) than processing speed ability ( r = .10). Thus, the FFDT is a reliable, valid, and specific measure of the ability to identify familiar faces, making it a promising new tool for assessing face recognition ability.

“…Although future research is necessary to determine what design parameters produce the most reliable and valid measure of familiar face recognition ability, we believe that the FFDT's use of cropped images on all trials and celebrity lures on 77.5% of trials decreases the likelihood of participants using non-facial information or familiarity cues to complete the test. Notably, the other doppelganger test (Meschke et al, 2018) has a unique strength of asking participants to rate their familiarity with target celebrities before beginning the main part of the test, which may be useful for more clearly differentiating face recognition ability from pop-culture exposure.…”

“…One unique aspect of voice recognition when compared to the parallel person individuation route of face recognition is that while familiar faces can be readily recognized from an unrestricted set of thousands of faces, e.g., "any celebrity" (e.g., Hacker et al, 2018), the accuracy of recognition of voices declines precipitously as the number of possible voices increases beyond a handful (Legge et al, 1984;Biederman, et al, 2018;Xu et al, 2015;Shilowich & Biederman, 2016). Furthermore, past studies utilizing familiar celebrity voices have mostly used unconstrained sets, with varying success rates as low as 10% (Meudell et al, 1980;Van Lancker et al, 1985;.…”

Voice recognition is a fundamental pathway to person individuation, although typically overshadowed by its visual counterpart, face recognition. There have been no large scale, parametric studies investigating voice recognition performance as a function of cognitive variables in concert with voice parameters. Using celebrity voice clips of varying lengths, 1-4 sec., paired with similar sounding, unfamiliar voice foils, the present study investigated three key voice parameters distinguishing targets from foils -- fundamental frequency, f0 (pitch), subharmonic-to-harmonic ratio, SHR (creakiness), and syllabic rate--in concert with the cognitive variables of voice familiarity and judged voice distinctiveness as they contributed to recognition accuracy at varying clip lengths. All the variables had robust effects in clips as short as 1 sec. Objective measures of distinctiveness, quantified by the distances of each target voice to that target’s sex- based mean for each parameter, showed that sensitivity to distinctiveness increased with familiarity. This effect was most evident on foil trials; at clip lengths of one second and above, f0 and SHR distinctiveness showed no discernible effect on match trials. Speaking rate distinctiveness improved match accuracy, an effect only seen with high familiarity. Recognition accuracy improved with the number of parameters that differed by an amount larger than the median, both in the target-to-foil and target-to-mean voice comparisons. A linear regression model of these three voice parameters, clip length, and subjective measures of distinctiveness and familiarity accounted for 36.7% of the variance in recognition accuracy.
