Contextual positivity-familiarity effects are unaffected by known moderators of misattribution.

ABSTRACTThe positivity-familiarity effect refers to the phenomenon that positive affect increases the likelihood that people judge a stimulus as familiar. Drawing on the assumption that positivity-familiarity effects result from a common misattribution mechanism that is shared with conceptually similar effects (e.g. fluency-familiarity effects), we investigated whether positivity-familiarity effects are qualified by three known moderators of other misattribution phenomena: (a) conceptual similarity between affect-eliciting prime stimuli and focal target stimuli, (b) relative salience of affect-eliciting prime stimuli, and (c) explicit warnings about the effects of affect-eliciting prime stimuli on familiarity judgments of the targets. Counter to predictions, three experiments obtained robust positivity-familiarity effects that were unaffected by the hypothesised moderators. The findings pose a challenge for misattribution accounts of positivity-familiarity effects, but they are consistent with alternative accounts in terms of affective monitoring.

The future is now: the impact of present fluency in judgments about the future.

Recent research has emphasised the role of episodic memory in both remembering past events and in envisaging future events. On the other hand, it has been repeatedly shown that judgments about past events are affected by the fluency with which retrieval cues are processed. In this paper we investigate whether perceptual fluency also plays a role in judgments about future events. For this purpose we conducted four experiments. The first experiment replicated recent findings showing that stimuli that are processed fluently tend to be wrongly recognised as having been encountered in the past outside the laboratory walls [Brown, A. S., & Marsh, E. J. (2009). Creating illusions of past encounter through brief exposure. Psychological Science, 20, 534-538. doi: 10.1111/j.1467-9280.2009.02337.x ]. Two follow-up experiments using Brown and Marsh's [(2009). Creating illusions of past encounter through brief exposure. Psychological Science, 20, 534-538. doi: 10.1111/j.1467-9280.2009.02337 ] task tested the influence of perceptual fluency on future judgments. The fourth and last experiment was designed to rule out a potential confounding factor in the two previous experiments. Across experiments, we found that people rely on fluency when making judgments about events that are yet to come. These results suggest that fluency is an equally valid cue for past and future judgments.

The effect of face race on metamemory: Examining its robustness and underlying mechanisms.

Perceivers typically exhibit better recognition memory for same-race faces than for cross-race faces, a phenomenon known as the cross-race effect (CRE). Despite its ubiquity, it is yet unclear whether people are metacognitively aware of the CRE. This research thoroughly investigates perceivers' metacognitive awareness of the CRE across five experiments. Experiments 1 and 2 demonstrated that both prospective (judgments of learning) and retrospective (confidence) metamemory judgments are sensitive to variations in the racial category and prototypicality of faces. Experiment 3 showed that participants' item-level prospective judgments are informed by beliefs about the impact of face race on memory performance. Experiment 4 revealed that global predictions are influenced by face race in the absence of direct stimulus experience, emphasizing the role of preexisting beliefs. Experiment 5 extended these findings by showing large crossover interactions between face race and participant race in both global predictions and item-level prospective judgments, indicating that both White and Black participants have higher metamemory estimates for ingroup faces. This experiment further showed that preexisting beliefs intensify the impact of face race on metamemory judgments yet do not fully account for it. Collectively, these experiments provide robust evidence of good metamemory accuracy for faces varying in racial categories and prototypicality among White participants and demonstrate that beliefs underlie the effect of face race on metamemory judgments among both White and Black participants, though this may not be the only mechanism involved.

Examining the Contribution of Physical Cues for Same- and Cross-Race Face Individuation.

Face individuation involves sensitivity to physical characteristics that provide information about identity. We examined whether Black and White American faces differ in terms of individuating information, and whether Black and White perceivers differentially weight information when judging same-race and cross-race faces. Study 1 analyzed 20 structural metrics (e.g., eye width, nose length) of 158 Black and White faces to determine which differentiate faces within each group. High-utility metrics (e.g., nose length, eye height, chin length) differentiated faces of both groups, low-utility metrics (e.g., face width, eye width, face length) offered less individuating information. Study 2 (N = 4,510) explored Black and White participants' sensitivity to variation on structural metrics using similarity ratings. High-utility metrics affected perceived dissimilarity more than low-utility metrics. This relationship was non-significantly stronger for same-race faces rather than cross-race faces. Perceivers also relied more on features that were racially stereotypic of the faces they were rating.

Nonlinear relationships between eye gaze and recognition accuracy for ethnic ingroup and outgroup faces.

Researchers have used eye-tracking measures to explore the relationship between face encoding and recognition, including the impact of ethnicity on this relationship. Previous studies offer a variety of conflicting conclusions. This confusion may stem from misestimation of the relationship between encoding and recognition. First, most previous models fail to account for the structure of eye-tracking data, potentially falling prey to Simpson's paradox. Second, previous models assume a linear relationship between attention (e.g., the number of fixations to a to-be-remembered face) and recognition accuracy. Two eye-tracking studies (Ns = 41, 59), one online experiment that manipulates exposure (N = 150), and a mega-analysis examine the effects of ethnicity using what we believe to be more appropriate analytical models. Across studies and measures, we document a novel, critical pattern: The relationship between attention and recognition is nonlinear and negatively accelerating. At low levels of baseline attention, a small increment in attention improves recognition. However, as attention increases further, increments yield smaller and smaller benefits. This finding parallels work in learning and memory. In models that allow for nonlinearity, we find evidence that central features (eyes, nose, and mouth) generally contribute to recognition accuracy, potentially resolving disagreements in the field. We also find that the effects of attention on recognition are similar for ingroup and outgroup faces, which have important implications for theories of perceptual expertise.

The effect of pre-event instructions on eyewitness identification.

Research on eyewitness identification often involves exposing participants to a simulated crime and later testing memory using a lineup. We conducted a systematic review showing that pre-event instructions, instructions given before event exposure, are rarely reported and those that are reported vary in the extent to which they warn participants about the nature of the event or tasks. At odds with the experience of actual witnesses, some studies use pre-event instructions explicitly warning participants of the upcoming crime and lineup task. Both the basic and applied literature provide reason to believe that pre-event instructions may affect eyewitness identification performance. In the current experiment, we tested the impact of pre-event instructions on lineup identification decisions and confidence. Participants received non-specific pre-event instructions (i.e., "watch this video") or eyewitness pre-event instructions (i.e., "watch this crime video, you'll complete a lineup later") and completed a culprit-absent or -present lineup. We found no support for the hypothesis that participants who receive eyewitness pre-event instructions have higher discriminability than participants who receive non-specific pre-event instructions. Additionally, confidence-accuracy calibration was not significantly different between conditions. However, participants in the eyewitness condition were more likely to see the event as a crime and to make an identification than participants in the non-specific condition. Implications for conducting and interpreting eyewitness identification research and the basic research on instructions and attention are discussed.

Learning what to inhibit: The influence of repeated testing on the encoding of gender and age information.

Psychological research has devoted considerable attention to the relationship between the multiple category dimensions that can be extracted from faces. In the present studies, we investigated the role of experience and learning on the way the social perceiver deals with multiple category dimensions. Specifically, we tested whether learning which of 2 dimensions is the most relevant to the task at hand influences the encoding and retrieval of both task-relevant and irrelevant dimensions. In our studies, participants went through several cycles, each consisting of a study and a test phase. We manipulated the structure of the tests such that participants were probed on only 1 category dimension (age or gender), despite viewing faces of both category dimensions in all study phases. We hypothesized that when participants were repeatedly tested on 1 dimension, they would proactively control their attention toward that specific dimension and away from the nonrelevant dimension. Five studies demonstrated that: (a) participants learned which dimension was test-relevant such that they gradually became faster and more accurate on that dimension; (b) when the gender dimension was test-relevant, participants were faster and more accurate retrieving information concerning the target faces' gender than age, while the opposite did not happen when the age dimension was test-relevant; and (c) this dominance of the gender dimension is mainly caused by the inhibition of the age dimension. Implications about the importance of previous experience and control for research on social categorization in general and research examining the interplay between gender and age are discussed.

Off the top of my head: Malleability and stability in natural categories.

Previous research has found that category representations are highly malleable knowledge structures, varying widely across different contexts and individuals. However, it has also been found that such malleability does not apply equally to all types of category information. The present research further investigates the representational malleability versus stability of natural taxonomic categories. Using perceptual fluency as means to induce malleability, we explored whether malleability is moderated by the degree of typicality of category information. In the first experiment, we found that fluency-based malleability only occurs for non-typical category information. In follow-up experiments, we investigated the boundary conditions under which such fluency-based malleability occurs. Namely, in Experiment 2, we showed that the effect of fluency on non-typical features disappeared when there is a sensory modality mismatch between study and test phases. Finally, in Experiment 3, we demonstrated that this effect reappears in the modality mismatch condition when participants are given a response deadline. The implications of these findings to current theories of category representation and the perceptual fluency literature are discussed.

At the Boundaries of Misattribution.

Priming effects in the Affect Misattribution Procedure (AMP) have been explained by a misattribution of prime-related affect to neutral targets. However, the measure has been criticized for being susceptible to intentional use of prime-features in judgments of the targets. To isolate the contribution of unintentional processes, the present research expanded on the finding that positive affect can be misattributed to familiarity (i.e., positivity-familiarity effect). To the extent that prime-valence is deemed irrelevant for judgments of target-familiarity, positivity-familiarity effects in the AMP could potentially rule out intentional use of the primes. Seven experiments collectively suggest that prime-valence influences judgments of target-familiarity in the AMP, but only when the task context does not suggest a normatively accurate response to the familiarity-judgment task. Relations of positivity-familiarity effects to self-reported use of prime-valence revealed mixed results regarding the role of intentional processes. Implications for the AMP and misattribution effects are discussed.
