Visuokinesthetic Realignment in a Video-Controlled Reaching Task

The authors investigated the accuracy of horizontal pointing movements toward a visual target viewed on a vertical video monitor; the view included a directional distortion between perceptual and action spaces. Although accurate coding of the movement vector in a relative (visual) system of coordinates has been found to occur when there is a prismatic perturbation, provided that the hand and the target are continuously visible, such accurate performance has never been reported for video-controlled situations with larger deviations. To evaluate whether visual relative coding is task specific or depends on the magnitude of the induced misalignment, the authors manipulated the intensity of directional perturbation (10° or 40°) in a video-controlled task. Whatever the directional bias, participants (N = 40) were initially inaccurate but adapted quickly within a few trial rehearsals, with a concomitant recalibration of segmental proprioception. In contrast with prism studies, relative coding of the hand-to-target vector seemed not to be operative in video-controlled situations, suggesting that target location is specified in an egocentric system of reference that includes hand-related proprioceptive signals, despite the presence of a (consciously) detected misalignment between visual and kinesthetic systems.     

Liberalism, entitlement, and verdict exclusion

In a series of recent papers, Crispin Wright has developed and defended an epistemic account of borderline cases which he calls ‘Liberalism’. If Verdict Exclusion is the claim that no polar verdict on borderline cases is knowledgeable, then Liberalism implies the view that Verdict Exclusion is itself nothing we are in a position to know. It is a matter of ongoing discussion what more Liberalism implies. In any case, Wright argues that Liberalism affords the means to account for the intuition that polar verdicts on borderline cases are equally permissible. Here I argue that Liberalism fails to deliver and that an account of borderline cases based on Verdict Exclusion fares much better when it comes to showing that our ordinary practice of reaching verdicts on borderline cases is fully legitimate: all it needs is a reassessment of the nature of the claims such verdicts express.     

Factors influencing juror verdict in a case involving repressed memories of abuse

Mental health professionals acting as expert witnesses are expected to testify about the prevalence of sexual abuse, and also about the veracity of memory. In cases involving adult survivors of sexual abuse, this testimony is typically about repressed and false memory syndromes. Many professionals have noted concerns about the lack of definitive data to support either syndrome. This study examined the following variables: juror knowledge and experience with repressed and false memory syndromes, juror attitudes about sexual abuse and memory recovery techniques, and gender of juror on verdict. Results include effects for repressed memory knowledge/experience and gender. Gender differences were found regarding attitudes about abuse and memory. Concluding comments include practical and research implications of the study results.

Reaching a Decision: A Reply to Oaksford

In his commentary, Oaksford makes two main claims: (1) that the externalisation method used by Green, Over, and Pyne (1997) enforces the correlation observed between probability estimates and selection, and (2) that these estimates support the prediction of a downward revision of P(p) when P(p) > P(q). In this reply, we rebut claim 1 by describing the instructions more comprehensively, and claim 2 by reiterating the importance of making certain theoretical distinctions which Oaksford does not make. Our interest is the psychological process of reaching decision: externalisation methods provide a means of exploring this process and of assessing the value of Bayesian approaches.     

Repressed memory lawsuits: Potential verdict predictors

This research examined the relationship between verdict and juror sex, ethnicity, religiosity and authoritarianism, and case type in lawsuits involving repressed memories of childhood sexual abuse. Subjects (N = 251) read excerpts from one of two hypothetical lawsuits (one involving claims of incest or one involving accusations of satanic ritual abuse; SRA), rendered an individual verdict, and responded to demographic questionnaires and measures of religiosity and authoritarianism. It was predicted that jurors who were female, highly religious, high authoritarian, or Mexican-American would be most likely to sympathize with the plaintiff, and that the SRA version would be less successful. Logit analysis yielded a main effect of sex on verdict and an interaction between sex, authoritarianism, and religiosity on verdict, both findings consistent with predictions. Hypotheses predicting main effects of ethnicity on verdict and case type on verdict did not find statistical support.     

Self-Corrected Reaching in a Three-Location Delayed-Response Search Task

Infants watched an experimenter hide a toy in one of three wells and then attempted to retrieve it after a brief delay. Seven-month-olds performed at chance. Nine-month-olds reached correctly on 43% of trials, which is significantly better than chance. After an incorrect reach, infants were allowed to choose between the two remaining locations. Seven-month-olds responded at a chance level on their second reach, but 9-month-olds chose correctly more often than would be expected by chance despite a 10- to 20-s delay between hiding and search. One cause of error on the initial reach was a profound bias toward the center well. In Experiment 2, the wells were covered simultaneously, and the infant's spatial orientation was disrupted during the delay; this procedure eliminated the centripetal bias. Nine-month-olds still responded correctly more often than would be expected by chance on their second reach. These findings suggest that 9-month-olds sometimes have a more durable working memory for location than is generally reported for that age group.     

Reaching while walking: Reaching distance costs more than walking distance

Surprisingly little is known about how people plan and control everyday physical actions, such as walking along and picking up objects. In order to explore this topic, we conducted an experiment in which university students were asked to pick up a common object (a child’s beach bucket) that stood on a table several meters from the participant’s start position. The bucket stood either on the left side, in the middle, or on the right side of the table and, depending on instructions, was to be carried to a farther target whose horizontal position was also varied. The questions were which side of the table the participant would walk along when picking up the bucket and which hand the participant would use to pick up and carry the bucket. Participants, most of whom were righthanded, preferred to walk along the left side of the table and to pick up the bucket with the right hand, although they departed from that preference when the reaching distance across the table was uncomfortable or if the target was too far to the right. The data were well fit with a mathematical model that included a right-hand bias and an estimate of functional distance that expressed the cost of reaching over some distance as approximately twice the cost of walking over the same distance.     

Evidence coverage and argument skills: cognitive factors in a juror's verdict choice

Juror reasoning and verdict choice have been explored variously as functions of argument skill and the overall story representation of the evidence on which verdict choices are based. This study investigates the proportion of testimony covered in the justification of a verdict choice and its relationship with argument skill, narrative explanation or evidence‐based argument, and certainty about verdict choice. Each of these variables was also compared with the verdict choice. People serving jury duty justified verdict choices in two abridged jury trials. Individuals were consistent in the relative amount of evidence used in both trials. Argument skills, evidence evaluation type, and evidence synthesis type all accounted for variance in the amount of evidence covered. Evidence coverage, along with argument skills, predicted verdict choice. As expected, those most certain about verdict choice did not use the most evidence. Implications regarding mediating factors in story construction and juror decision making are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Guilty but mentally ill: An alternative verdict

Despite opposition from professional groups such as the American Psychiatric Association and the American Bar Association, “Guilty But Mentally Ill” (GBMI) statutes now exist in at least 12 states and are being considered in others. This paper reviews the development of the GBMI alternative to the insanity defense from a historical perspective, focusing especially on the reasons for its development in Michigan, the first state to pass GBMI legislation over 9 years ago. Using the Michigan experience, the GBMI statute is reviewed in terms of its perceived purpose and its success in accomplishing that purpose. Then recommendations for future changes are made.     

Knowledge-telling and knowledge-transforming arguments in mock jurors' verdict justifications

According to the “story model” a juror constructs an implicit mental model of a story telling what happened as the basis for the verdict choice. But the explicit justification of a verdict choice could take the form of a story (knowledge telling) or the form of a relational (knowledge-transforming) argument structure that brings together diverse, non-chronologically related pieces of evidence. The study investigates whether people tend towards knowledge telling or knowledge transforming, and whether use of these argument structure types are related to skilled argument and epistemic understanding. A sample of people on jury duty chose and justified verdicts in two abridged cases. Participants tended to display the same argument structure and argument skill across cases. Those using knowledge-transforming structures were more successful at the juror argument skills task and had a higher level of epistemic understanding. The discussion suggests that jurors approach their task with an epistemic orientation towards knowledge telling or knowledge transforming.     

Predictors of verdict and punitive damages in high-stakes civil litigation

This research investigated demographic and attitudinal- psychological predictors of verdict and amount of punitive damages awarded in high-stakes civil litigation. Four hundred and forty-six surrogate jurors, selected to be representative of actual jurors, were exposed to realistic case presentations in insurance, tobacco, and pharmaceutical cases that were about to go to trial. Hierarchical regression revealed that perceptions of the existence of a litigation crisis predicted verdict in the tobacco and pharmaceutical cases after controlling for all other variables. Demographic variables predicted verdict and punitive damage awards only modestly and in different ways in the three cases. Need for cognition, strength of will and rationality, and a perception that there is a litigation crisis predicted the amount of punitive damages awarded in the tobacco case. Litigation crisis also predicted the amount of punitive damages awarded in the pharmaceutical case. Implications for jury selection are discussed.     

Perception of Maximum Reaching Height When the Means of Reaching Are No Longer in View

Previous research has shown that perception of maximum reaching height is relative to reaching ability even when the means of performing this behavior would bring about (future) changes in reaching ability. Two experiments investigate whether this continues to be the case even when the means of reaching are no longer in view. The results show perception of maximum reaching height reflects impending changes to reaching ability both when the means of performing the reaching task (and changing reaching ability) are present and when they are no longer in view. The results are discussed in the context of prospectivity, retrospectivity, and flexibility—3 fundamental hallmarks of goal-directed behavior.     

Reaching the Champions of Social Justice

Since the formation of the World Council of Churches (WCC) in 1948, the ecumenical voice against social injustice in the church and society has been strengthening. As one expression of unity among the fellowship, the WCC embarked in 2013 on a Pilgrimage of Justice and Peace to work, pray, and walk together for life-affirming economies, climate change, nonviolent peace building, and reconciliation and human dignity. Champions of these issues exist within the ecumenical movement. Yet one also finds that champions of one theme are pushing back on another theme. Sometimes it is due to diversity of contexts and biblical and theological interpretations. At other times it is due to unconscious bias about the holistic nature of God's mission of justice for all God's people and creation. This paper grapples with this question: Why are people who are so alive to economic and ecological injustice sometimes blind to racial and gender injustice? To answer this, I explore the existence of conscious and unconscious bias despite the many powerful ecumenical statements that have been issued on racial justice.
