Laypeople's beliefs about the effects of common estimator variables on memory.

This research builds on James Ost's research investigating whether laypeople's beliefs align with those of experts. Recent studies that examined the relationship between high-confidence eyewitness identifications and accuracy proposed that the mechanism underlying this relationship may be based on a knowledge-conditional model. According to this model, the accuracy of a confidence judgment depends on knowledge about factors that affect memory accuracy.

Elevated stress impairs the accuracy of eyewitness memory but not the confidence-accuracy relationship.

Although numerous studies have identified factors that affect eyewitness identification accuracy, recent studies report that many of these factors do not affect the accuracy of high-confidence identifications. This is critical because legal cases are more likely to be prosecuted if they involve high-confidence eyewitnesses. Using a confidence-accuracy characteristic (CAC) analysis, we explored whether stress affects the accuracy of high-confidence identifications.

Target-related autobiographical memories affect dietary intake intentions.

Although there is evidence that autobiographical memory (AM) recall impacts behaviour in multiple domains, the mechanisms for this effect are unclear. Two experiments examined how AM Frame and Relatedness to target behaviour affect intention to control future dietary intake Participants completed an AM task where they recalled success or fail-framed memories of behaviour in the target domain (dietary intake), a related domain (exercise), and an unrelated domain (work). Next they completed questionnaires about attitudes, self-efficacy, and behavioural intention for controlling dietary intake.

Postdictive confidence (but not predictive confidence) predicts eyewitness memory accuracy.

If testing conditions are uncontaminated, confidence at test reliably predicts eyewitness memory accuracy. Unfortunately, information about eyewitness postdictive confidence (at the time of the identification test) is frequently unavailable or not well documented. In cases where postdictive confidence is unavailable, a useful indicator of eyewitness accuracy might be an eyewitness's predictive confidence made shortly after the event.

Evidence for a confidence-accuracy relationship in memory for same- and cross-race faces.

Discrimination accuracy is usually higher for same- than for cross-race faces, a phenomenon known as the cross-race effect (CRE). According to prior research, the CRE occurs because memories for same- and cross-race faces rely on qualitatively different processes. However, according to a continuous dual-process model of recognition memory, memories that rely on qualitatively different processes do not differ in recognition accuracy when confidence is equated.

A meta-analysis of children's self-reports of dietary intake.

Objective: Although research studies increasingly use children as primary reporters in dietary assessments, it is unclear how well children's self-reported intake correlates with independently validated reports of their intake; this meta-analysis assesses that correlation.

Design: Moderators of the correlation between self-reported and independently validated intake were predicted a priori: type of dietary intake assessment (24 h recall, food diary and food frequency questionnaires), validation measures, parental assistance and age. Online databases were searched for articles published from 1990 to 2014 that compared children's self-reports of dietary intake to validated observations of food intake in children age 4-16.

The cross-race effect in face recognition memory by bicultural individuals.

Social-cognitive models of the cross-race effect (CRE) generally specify that cross-race faces are automatically categorized as an out-group, and that different encoding processes are then applied to same-race and cross-race faces, resulting in better recognition memory for same-race faces. We examined whether cultural priming moderates the cognitive categorization of cross-race faces. In Experiment 1, monoracial Latino-Americans, considered to have a bicultural self, were primed to focus on either a Latino or American cultural self and then viewed Latino and White faces.

Postencoding cognitive processes in the cross-race effect: Categorization and individuation during face recognition.

The cross-race effect (CRE) describes the finding that same-race faces are recognized more accurately than cross-race faces. According to social-cognitive theories of the CRE, processes of categorization and individuation at encoding account for differential recognition of same- and cross-race faces. Recent face memory research has suggested that similar but distinct categorization and individuation processes also occur postencoding, at recognition.

Imagination perspective affects ratings of the likelihood of occurrence of autobiographical memories.

Two experiments tested and confirmed the hypothesis that when the phenomenological characteristics of imagined events are more similar to those of related autobiographical memories, the imagined event is more likely to be considered to have occurred. At Time 1 and 2-weeks later, individuals rated the likelihood of occurrence for 20 life events. In Experiment 1, 1-week after Time 1, individuals imagined 3 childhood events from a first-person or third-person perspective.

The effect of nonprobative photographs on truthiness persists over time.

When making rapid judgments about the truth of a claim, related nonprobative information leads people to believe the claim-an effect called "truthiness" (Newman, Garry, Bernstein, Kantner, & Lindsay, 2012). For instance, within a matter of seconds, subjects judge the claim "The Mona Lisa has no eyebrows," to be true more often when it appears with a photograph of the Mona Lisa viewed at a distance by a person. But does truthiness persist longer than a few seconds? To determine if truthiness "sticks," we asked people to judge if each trivia claim in a series was true.

Oxytocin eliminates the own-race bias in face recognition memory.

The neuropeptide Oxytocin influences a number of social behaviors, including processing of faces. We examined whether Oxytocin facilitates the processing of out-group faces and reduce the own-race bias (ORB). The ORB is a robust phenomenon characterized by poor recognition memory of other-race faces compared to the same-race faces.

Cross-race (but not same-race) face identification is impaired by presenting faces in a group rather than individually.

This study extends the research on cross-race identification by examining how group presentation of faces influences the cross-race effect (CRE) and confirming systematic qualitative differences between the cognitive processes involved in memory for same- and cross-race faces. White individuals viewed 16 target faces (8 White, 8 Black) presented individually or each in a 3-face group. The conditions that impaired cross-race but not same-race face recognition memory were (a) group compared to individual presentation of target faces (Experiment 1), and (b) presentation of target faces in homogeneous (foil faces matched the race of the target face) rather than heterogeneous groups (foil faces did not match the race of the target face; Experiment 2).

Interviewing child witnesses: the effect of forced confabulation on event memory.

Age differences in rates of forced confabulation and memory consequences thereof were assessed using a recall task similar to real forensic interview procedures. Children viewed a target video and were tested with the same 18 questions immediately afterward and 1 week later. Of the 18 questions, 12 were answerable; the 6 unanswerable questions referred to information not in the video.

Motivated forgetting and misremembering: perspectives from betrayal trauma theory.

Individuals are sometimes exposed to information that may endanger their well-being. In such cases, forgetting or misremembering may be adaptive. Childhood abuse perpetrated by a caregiver is an example.

Forced confabulation affects memory sensitivity as well as response bias.

A signal detection analysis assessed the extent to which forced confabulation results from a change in memory sensitivity (d(a)), as well as response criterion (β). After viewing a crime video, participants answered 14 answerable and 6 unanswerable questions. Those in the voluntary guess condition had a "don't know" response option; those in the forced guess condition did not.

The development of memory for own- and other-race faces.

This study demonstrates that experience and development interact to influence the "cross-race effect." In a multination study (n=245), Caucasian children and adults of European ancestry living in the United States, Norway, or South Africa, as well as biracial (Caucasian-African American) children and adults living in the United States, were tested for recognition of Asian, African, and Caucasian faces. Regardless of national or biracial background, 8- to 10-year-olds, 12- to 14-year-olds, and adults recognized own-race faces more accurately than other-race faces, and did so to a similar extent, whereas 5- to 7-year-olds recognized all face types equally well.

Is knowing believing? The role of event plausibility and background knowledge in planting false beliefs about the personal past.

False memories are more likely to be planted for plausible than for implausible events, but does just knowing about an implausible event make individuals more likely to think that the event happened to them? Two experiments assessed the independent contributions o f plausibility a nd background knowledge to planting false beliefs. In Experiment 1, subjects rated 20 childhood events as to the likelihood of each event having happened to them. The list included the implausible target event "received an enema," a critical target event of Pezdek, Finger, and Hodge (1997).

Imagination and memory: does imagining implausible events lead to false autobiographical memories?

Previous studies have reported that imagination can induce false autobiographical memories. This finding has been used to suggest that psychotherapists who have clients imagine suspected repressed memories of childhood sexual abuse may, in fact, be inducing false memories for the imagined events. In this study, at Time 1 and then, 2 weeks later, at Time 2, 145 subjects rated each of 20 events on the Life Events Inventory as to whether each had occurred to them in childhood.

Interviewing witnesses: the effect of forced confabulation on event memory.

After viewing a crime video, participants answered 16 answerable and 6 unanswerable questions. Those in the "voluntary guess" condition had a "don't know" response option; those in the "forced guess" condition did not. One week later the same questions were answered with a "don't know" option.

What research paradigms have cognitive psychologists used to study "false memory," and what are the implications of these choices?

This research examines the methodologies employed by cognitive psychologists to study "false memory," and assesses if these methodologies are likely to facilitate scientific progress or perhaps constrain the conclusions reached. A PsycINFO search of the empirical publications in cognitive psychology was conducted through January, 2004, using the subject heading, "false memory." The search produced 198 articles.

Detecting deception in children: an experimental study of the effect of event familiarity on CBCA ratings.

The CBCA is the most commonly used deception detection. technique worldwide. Pezdek et al.

Detecting deception in children: event familiarity affects criterion-based content analysis ratings.

Statement Validity Assessment (SVA) is a comprehensive credibility assessment system, with the Criterion-Based Content Analysis (CBCA) as a core component. Worldwide, the CBCA is reported to be the most widely used veracity assessment instrument. We tested and confirmed the hypothesis that CBCA scores are affected by event familiarity; descriptions of familiar events are more likely to be judged true than are descriptions of unfamiliar events.

Children's face recognition memory: more evidence for the cross-race effect.

It is well established that own-race faces are recognized more accurately than cross-race faces. However, there are mixed results regarding the developmental consistency of the cross-race effect White and Black kindergarten children, 3rd graders, and young adults viewed a Black and a White target individual. One day later, recognition memory for each target was tested with a 6-person lineup.
