Who? What? When? Using a timeline technique to facilitate recall of a complex event

Accurately recalling a complex multi-actor incident presents witnesses with a cognitively demanding retrieval task. Given the important role played by temporal context in the retrieval process, the current research tests an innovative timeline technique to elicit information about multiple perpetrators and their actions. Adopting a standard mock witness paradigm, participants were required to provide an account of a witnessed event. In Experiment 1, the timeline technique facilitated the reporting of more correct details than a free recall, immediately and at a two-week retention interval, at no cost to accuracy. Accounts provided using the timeline technique included more correct information about perpetrator specific actions and fewer sequencing errors. Experiment 2 examined which mnemonic components of the timeline technique might account for these effects. The benefits of exploiting memory organization and reducing cognitive constraints on information flow are likely to underpin the apparent timeline advantage.     

Context and Prior Impression Effects on Attention, Judgment Standards, and Ratings: Contrast Effects Revisited

The present study extended research on contrast effects by (a) examining the effect of context performances on ratings of a target performance when a prior impression of the target performer already exists, and (b) clarifying the issue of whether contrast is caused by attention to context-discrepant behavior or shifts in judgment standards. The results demonstrated that the existence of a prior impression mitigates the influence of context performances on ratings. Judgment standards were found to be unstable and dependent on information provided to raters by the experimental manipulations. Regression analyses showed that both attention and standards of judgment mediate the relationship between context and ratings. Implications of these findings for contrast effects, performance ratings, and the importance of reliable judgment standards for real-world performance appraisals are discussed.     

Emergent persons

Recent psychological theorizing about the emergence of persons makes a number of ontological claims that are not always explicit. A critical consideration of such claims reveals both considerable convergence and some points of disagreement across different psychological theories of emergent personhood. What is clear is that all such theories resist the reduction of persons to biophysical or sociocultural properties, conditions, and processes. In various ways, they each call for a nonreductionistic recognition of the sociocultural constitution of important aspects of personhood, without denying the necessity of biophysical requirements of personhood. Because standard emergentist positions in physical science and the philosophy of physical science mostly ignore the sociocultural level of reality, psychological theorizing about the emergence of persons requires an alternative ontological framework. It is proposed that an ontology of levels of reality that includes the physical, chemical, biological, sociocultural, and personal/psychological is appropriate for understanding how persons are both substantively and relationally emergent within the biophysical, sociocultural world. With such an ontological framework in place, it is possible to understand human activity in the world as the primary vehicle for both the phylogenetic evolution and ontogenetic development of persons.     

Memory conformity: can eyewitnesses influence each other's memories for an event?

The current study investigated memory conformity effects between individuals who witness and then discuss a criminal event, employing a novel procedure whereby each member of a dyad watches a different video of the same event. Each video contained unique items that were thus seen only by one witness. Dyads in one condition were encouraged to discuss the event before each witness (individually) performed a recall test, while in a control condition dyads were not allowed to discuss the event prior to recall. A significant proportion (71%) of witnesses who had discussed the event went on to mistakenly recall items acquired during the discussion. There were no age‐related differences in susceptibility to these memory conformity effects in younger (18–30 years) as compared to older (60–80 years) participants. Possible social and cognitive mechanisms underlying the distortions of memory due to conformity are discussed. Copyright © 2003 John Wiley & Sons, Ltd.
