Objective: Despite the risks inherent to custodial police interrogation, criminal suspects may waive their rights and submit to police questioning in fear that exercising their rights or remaining silent will make them appear guilty. We tested whether such a penalty exists.
Hypotheses: We predicted that people would perceive suspects who invoke their rights or sit in silence during an interrogation as more likely to be guilty than those who waive their rights.
Recent research on the eyewitness confidence-accuracy relationship reveals that confidence can be highly diagnostic of accuracy when the identification evidence is collected using pristine procedures (Wixted & Wells, 2017) and in the absence of suspect bias (Smalarz, 2021). Some researchers have further argued that eyewitnesses who make high-confidence suspect identifications are highly likely to be accurate even if they experienced suboptimal witnessing conditions (Semmler et al., 2018).

Hypotheses: In Experiment 1, we predicted that the stigma of wrongful conviction would be greater for Black than White exonerees.
Objective: Despite documented racial disparities in all facets of the criminal justice system, recent laboratory attempts to investigate racial bias in legal settings have produced null effects or racial-bias reversals. These counterintuitive findings may be an artifact of laboratory participants' attempts to appear unprejudiced in response to social norms that proscribe expressions of racial bias against Black individuals. Furthermore, given pervasive stereotypes linking Black people with crime and heightened attention to issues of racial injustice in the legal system, laboratory participants may be especially likely to attempt to appear unprejudiced in studies examining judgments of Black individuals in legal as opposed to nonlegal contexts.

We explored the role of social desirability in these counterintuitive effects and tested whether allowing participants to establish nonracist moral credentials increased their willingness to convict a Black defendant.
Hypotheses: We predicted that establishing nonracist moral credentials would increase convictions of Black defendants-especially for participants likely to harbor racial bias and external motivation to control it.
Objectives: We assessed recent policy recommendations to collect eyewitnesses' confidence statements in witnesses' own words as opposed to numerically. We conducted an experiment to test whether eyewitnesses' free-report verbal confidence statements are as diagnostic of eyewitness accuracy as their numeric confidence statements and whether the diagnostic utility of eyewitnesses' verbal and numeric confidence statements varies across witnessing conditions.
Hypotheses: We hypothesized that eyewitnesses' verbal and numeric confidence statements are both significantly associated with identification accuracy among choosers and that their diagnostic utility holds across varying witnessing conditions.
This research tested whether the perception of threat during a police interrogation mobilizes suspects to cope with interrogation demands and bolsters their resistance to self-incrimination pressures. Experimental procedures led university undergraduates (N = 296) to engage in misconduct or not, thereby making them guilty or innocent. An experimenter then accused all participants of misconduct in either a threatening or nonthreatening way.

The model estimates the expected cost of an identification procedure in order to quantify how well the procedure helps the police achieve the investigation goal of identifying and incriminating the culprit. We first apply the expected cost model to analyze five major procedural reforms, including showups versus lineups, filler similarity, administrator influence, lineup instruction, and presentation format.

According to this process, the initial threat of police interrogation mobilizes suspects to resist interrogative influence in a manner akin to a fight or flight response, but suspects' protracted self-regulation of their behavior during subsequent questioning increases their susceptibility to interrogative influence in the long-run. In Experiment 1 (N = 316), participants who were threatened by an accusation of misconduct exhibited responses indicative of mobilization and more strongly resisted social pressure to acquiesce to suggestive questioning than did participants who were not accused.

We describe why eyewitness identification is a natural Bayesian problem and how numerous important observations require careful consideration of base rates. Moreover, we argue that the base rate in eyewitness identification should be construed as a system variable (under the control of the justice system).

We also examined whether the degree of similarity between a mistakenly identified individual and the actual culprit plays a role in memory impairment. Participant-witnesses (N = 145) made mistaken identifications from a "similar" or a "dissimilar" culprit-absent photo lineup.

The findings of the current research provided evidence that this preexisting vulnerability is exacerbated by factors that are associated with the immediate interrogation situation. In Experiment 1 (N = 118), a lengthy interview exacerbated participants' tendency to temporally discount a distal consequence when deciding whether or not to admit to criminal and unethical behaviors.

The goal of the present research was to determine whether awareness of this perpetual foreigner stereotype predicts identity and psychological adjustment. We conducted a series of studies with 231 Asian Americans and 211 Latino/as (Study 1), 89 African Americans (Study 2), and 56 Asian Americans and 165 Latino/as (Study 3).
