In the Image of the Triune God

This programmatic article addresses the question of how the creation of human beings in the image of God can be made specifically trinitarian. It does this by considering the ways in which human life can image forth the particular personal characteristics of each of the divine persons, and by examining how that imaging forth is distorted by the reality of sin.     

Double Exposure: The Effects of Repeated Identification Lineups on Eyewitness Accuracy

Eyewitnesses may be asked to identify the same suspect from a lineup on successive occasions. This study explored the effects on eyewitness decisions of repeated same‐suspect lineups, within a 2 × 2 × 2 mixed‐model factorial design. Witnesses to a video crime attempted to identify the culprit from two same‐format lineups (simultaneous or sequential) separated by a 2‐week retention interval (Lineup1, Lineup2) in which a suspect (guilty or innocent) was common to the lineups. We predicted two components of a posited repeated lineup effect: that positive identification errors made at the first lineup would be carried forward rather than corrected at the second lineup and that the number of false identifications of the innocent suspect would rise from first to second lineup. Predictions were supported, with a stronger negative impact of repeated lineups for simultaneous than sequential lineups. Additionally, witnesses who made selections of the guilty suspect and of the innocent suspect at Lineup2 were equally confident and were significantly more confident than witnesses who declined to pick. The results underscore concerns about possible negative outcomes from repeated lineups. Copyright © 2013 John Wiley & Sons, Ltd.     

Delay and Age Effects on Identification Accuracy and Confidence: An Investigation Using a Video Identification Parade

A total of 236 children (7–8‐year‐olds and 13–14‐year‐olds) attempted identification from either target‐present (TP) or target‐absent (TA) video parades, after either two days or two weeks, following exposure to a live target. It was found that with TP line‐ups, the most frequent response was a correct identification, but in the TA condition, the most frequent response was a false identification. Under both TP and TA conditions, the 3‐way interaction of delay, age and response was significant. Further analysis revealed that delay was the major contributor of variance, causing an increase in errors for both age groups in TP delayed line‐ups but only for the younger age group in TA delayed line‐ups. Confidence varied as a function of type of identification response made, with the highest confidence being given to a correct identification in a TP line‐up. However, response confidence entered into a number of interactions involving both delay and age. Copyright © 2011 John Wiley & Sons, Ltd.     

Facilitating Accuracy in Showup Identification Procedures: The Effects of the Presence of Stolen Property

Law enforcement personnel regularly present suspects to eyewitnesses using showups. In this study, we examined the impact of the presence of stolen property on live showup identification performance. Two hundred seventy university students were exposed to a simulated theft. During the subsequent showup, we manipulated the presence of the target and stolen property. Binary logistic regression analyses indicated that both factors independently predicted the accuracy of identification decisions. Participants were more accurate when the target was in the showup and when the stolen property was present during the identification. Consistent with the item, context, and ensemble theory of recognition, the presence of stolen property led to an increase in sensitivity, suggesting ensemble formation. Future research on showups should continue to examine contextual variables that may lead to changes in sensitivity or criterion shift. Copyright © 2012 John Wiley & Sons, Ltd.     

Holistic Facial Composite Construction and Subsequent Lineup Identification Accuracy: Comparing Adults and Children

When the police have no suspect, they may ask an eyewitness to construct a facial composite of that suspect from memory. Faces are primarily processed holistically, and recently developed computerized holistic facial composite systems (e.g., EFIT-V) have been designed to match these processes. The reported research compared children aged 6–11 years with adults on their ability to construct a recognizable EFIT-V composite. Adult constructor's EFIT-Vs received significantly higher composite-suspect likeness ratings from assessors than children's, although there were some notable exceptions. In comparison to adults, the child constructors also overestimated the composite-suspect likeness of their own EFIT-Vs. In a second phase, there were no differences between adult controls and constructors in correct identification rates from video lineups. However, correct suspect identification rates by child constructors were lower than those of child controls, suggesting that a child's memory for the suspect can be adversely influenced by composite construction. Nevertheless, all child constructors coped with the demands of the EFIT-V system, and the implications for research, theory, and the criminal justice system practice are discussed.     

Facial Wipes don't Wash: Facial Image Comparison by Video Superimposition Reduces the Accuracy of Face Matching Decisions

In cases of disputed CCTV identification, expert testimony based on the results of analysis by facial image comparison may be presented to the Jury. However, many of the techniques lack empirical data to support their use. Using a within‐participants design, we compared the accuracy of face‐matching decisions when images were presented using a ‘facial wipe’ technique (where one image is superimposed on another and the display gradually ‘wipes’ between the two) with decisions based on static images. Experiment 1 used high‐quality image pairs; Experiment 2 used disguised target images; and Experiment 3 used degraded target images. Across all three experiments, rather than optimising performance, facial wipes reduced accuracy relative to static presentations. Further, there is evidence that video wipes increase false positives and therefore may increase the likelihood that images of two different people will be incorrectly judged to show the same individual.Copyright © 2016 John Wiley & Sons, Ltd.     

Biased Lineup Instructions: Examining the Effect of Pressure on Children's and Adults' Eyewitness Identification Accuracy1

Two experiments were conducted to examine the effects of pressure on lineup decisions across child and adult eyewitnesses. In both experiments, participants were exposed to a target via videotape and then presented with a 6‐person, target‐absent lineup. Pressure was manipulated via lineup instructions (neutral vs. biased instructions). With neutral lineup instructions, children had a higher false‐positive rate than did adults. With biased lineup instructions, children's patterns of false‐positive responding paralleled that of adults; that is, an increase in false positives occurred. These results suggest that social pressure may not be the only factor driving children's higher false‐positive responding, compared to adults. Potential factors that may be affecting children's lineup decision processes are discussed.     

Classical Psychophysics and the Assessment of Agreement and Accuracy In Judgments of Personality

ABSTRACT The just noticeable difference (jnd) unit of classical psycho-physics is introduced as a new way to describe accuracy and agreement in observer evaluations of personality. A formula for estimating jnd's from typically available summary statistics is derived from Thurstone's law of comparative judgment. A study examining four traits judged in 10 samples of subjects where the design permitted the calculation of jnd's by the method of paired comparisons indicated that the formula predicted the empirically derived jnd's associated with the mean judge ratings with considerable precision. Jnd's of criterion measures were also predicted, and while fit was somewhat less impressive in this case, there was still appreciable convergence between predicted and empirical values. The implications of jnd measures of agreement and accuracy are discussed. These implications include (a) possibilities for increased understanding of bias in observer judgments, (b) a new recognition that equal correlations to external criteria do not necessarily imply equal accuracy, and (c) alternative ways of describing the magnitude of effect in psychological research.     

Forming Composites of Cognitive Ability and Alternative Measures to Predict Job Performance and Reduce Adverse Impact: Corrected Estimates and Realistic Expectations

Although there has been empirical attention paid to the criterion‐related validity of predictor composites, there has been much less attention paid to the standardized ethnic group differences associated with these composites. One important area of inquiry in predictor composite research is the influence of adding predictors to a test of general mental ability. The limited empirical literature on this practice is mixed, but the prevailing expectation is that there is likely to be higher validity and less adverse impact. Unfortunately, much of the previous work is limited by the presence of inaccurate validity and standardized ethnic group difference values. In this analysis we formed meta‐analytic matrices to more accurately estimate the validity and standardized ethnic group differences of several composites that combine a measure of cognitive ability with measures of conscientiousness, a structured interview, or biodata. While results were somewhat complex, we found that adding alternative predictors does not result in a situation in which validity automatically goes up and adverse impact potential automatically goes down. In fact, the reductions in adverse impact (if any) from adding “non‐cognitive” predictors were more modest than much of the literature suggests.     

Accuracy and Confidence in Person Identification: The Relationship Is Strong When Witnessing Conditions Vary Widely

We hypothesized that both accuracy and confidence in suspect identifications depend, in part, on participants' ability to identify the target, and that both accuracy and confidence therefore tend to be higher under conditions that lead to good memory for the target than under conditions that lead to poor memory for the target. Furthermore, we hypothesized that a substantial correlation between accuracy and confidence will be observed if, because of variations in conditions, there is considerable variability across participants in ability to identify the target. Consistent with these hypotheses, manipulations that affected accuracy also affected confidence in the same direction, and when data were collapsed across conditions the accuracy-confidence correlation was substantial (mean r = .59).     

The Mystery Man Can Help Reduce False Identification for Child Witnesses: Evidence from Video Line‐ups

It is well established that children (as young as 5 years) can correctly identify a target from a target present (TP) line‐up as accurately as adults; however, when shown a target absent (TA) line‐up, children make more false identifications. In the present study, children aged 5–7 and 8–11 years viewed a film of a staged theft, then 1–2 days later were shown either a TP or TA video line‐up. Half of the witnesses viewed line‐ups that included a ‘mystery man’ (a black silhouette with a white question mark), which they could select if they did not recognise anyone from the line‐up. When the ‘mystery man’ was present in the line‐up, there were significantly fewer false identifications for the TA line‐ups. This study shows that including a silhouette in a video line‐up can help reduce false identifications for children as young as 5 years of age, without reducing correct identifications.

The Effects of the Cognitive Interview on Recall,Identification, Confidence and the Confidence/Accuracy Relationship

The effects of two interview techniques, the Cognitive Interview (CI) and the Structured Interview (SI), were examined in relation to recall, recognition, confidence and the confidence/accuracy relationship. Volunteer subjects witnessed a live staged event, and at set time delays (48 and 96 hours) were interviewed by means of either the CI or SI and made lineup identifications from both blank and filled lineup presentations. The CI significantly improved total recall (p<0.001) and correct recall (p<0.001) relative to the SI. There were no differences in either accuracy or error rates for the two conditions. The CI produced significantly higher ‘pre-post interview’ confidence ratings than the SI (p<0.05). Within-, between- and event-confidence ratings were not predictive of recall or recognition accuracy. Failure to find a significant consistent confidence/accuracy relationship was suggested to have occurred because of the operation of an accuracy assessment heuristic. The CI did not reliably improve identification from a filled lineup presentation relative to the SI, but did produce better performance on a blank lineup presentation (p<0.001). Confidence and the confidence/accuracy relationship involving identifications were not found to differ as a function of interview condition. Throughout the study multiple regression analyses failed to reveal consistent predictors of recall or recognition accuracy, confidence or the confidence/accuracy relationship of these two domains. © 1997 by John Wiley & Sons, Ltd.

Identification,Reflection, And Correlation: Problems In The Bases Of Repertory Grid Measures

Repertory grids, deriving from George Kelly's personal construct theory, have been used to provide measures of a number of personality and cognitive variables. Several of these grid measures, such as the identification index, some measures of cognitive complexity, and other indices extracted from factor analyses of grids, are based on correlations between the columns (elements) of the grid data matrix. These measures are problematic and unstable because the intercolumn correlations depend on the direction of scoring across each of the matrix rows (constructs). This direction is not guided by explicit or theoretically justified rules and appears to be arbitrary and inconsistent between researchers. Also, correlation is a poor measure of element similarity, the basis of the identification measure. The importance of the valuating aspect of construing may provide a basis for the standardization of scoring. And scoring from the valued pole of a construct may help bring stability and meaning to the correlation-based measures.

Meta‐stereotypes,Social Image and Help Seeking: Dependency‐Related Meta‐stereotypes Reduce Help‐Seeking Behaviour

People who need help can be reluctant to seek it. This can be due to social image concerns. Here, we investigate if these concerns may be prompted by a salient negative meta‐stereotype: the belief that one's group is judged negatively by another group. Specifically, we researched group members' help‐seeking behaviour in the context of a dependency‐related meta‐stereotype. In a two‐condition study (N = 45), we manipulated participants' belief that their national group was judged dependent by a significant out‐group. We then examined their subsequent help‐seeking behaviour on a real‐world task. Participants whose social identity as a group member was salient showed greater reluctance to seek help when the meta‐stereotype was made prominent compared with when it was not. This suggests that, in a context where social image and social identity concerns are relevant, group members are willing to sacrifice the possibility of accessing needed help in order to avoid confirming a negative stereotype of their group. The implications of these results for helping transactions and community development are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Image Theory: Testing the Role of Image Compatibility in Progress Decisions

Image compatibility, one of Image Theory′s (Beach & Mitchell, 1987; 1990) most instrumental components, was tested in two lab studies. Consistent with theory propositions, results show that when perceptions of a project′s current and target images were more compatible, decision makers were more inclined to continue a project and more willing to commit additional resources. This pattern was found when project performance feedback was positive or negative (Experiment 1), or merely framed in a positive or negative manner (Experiment 2). Moreover, data from both studies indicated that image compatibility accounted for significant variance over and above that predicted by feedback sign and dissatisfaction with project performance alone. Results are discussed in terms of their contribution to the current status of the Image Theory paradigm and as a basis from which future research might build.

Image Interpretation: Bridging the Gap from Mechanically Produced Image to Representation

There is currently a gap in our understanding of how figures produced by mechanical imaging techniques play evidential roles: several studies based on close examination of scientific practice show that imaging techniques do not yield data whose significance can simply be read off the image. If image-making technology is not a simple matter of nature re-presenting itself to us in a legible way, just how do the images produced provide support for scientific claims? In this article I will first show that there is a distinct question about the semiotics of mechanically produced images that has not yet been answered. I show that my account of visual representations can do so, and I argue that the role of convention involved in my account is compatible with the view that visual representations produced through mechanized imaging techniques can play genuine evidential roles in scientific reasoning.
