Purposive behaviour in cognition and perception: Considerations of awareness in memory

The responses to the original article by Rönnberg (1990a) provoked interesting and thoughtful points of view that are covered by Gärling (1990), Hjelmquist (1990), Montgomery (1991), and Runeson (1990). These articles do not merely present a different outlook but also provide concepts that are certainly worthy of consideration and add more substance to the general topic under discussion. The purpose of this commentary is to seek an understanding of the ideas presented by the above authors within a synthesis of our views of current conceptualizations in cognition and perception. Each of the original criteria (Rönnberg, 1990a) will be treated in turn.     

Stimulus control of delayed matching in pigeons: Directed forgetting

Pigeons were trained in delayed matching-to-sample with two postsample stimuli. A postsample R-cue signaled that a matching choice phase would follow. A postsample F-cue signaled that a matching choice phase would not follow. Previous research found reduced matching accuracy on F-cued probe trials when comparison stimuli were presented in the choice phase. The present four experiments systematically varied the events following an F-cue to determine the conditions under which the F-cue reduces delayed-matching accuracy. When F-cues and R-cues controlled different behavior, matching on probe trials was poor. When both cues controlled the same behavior, matching on probe trials was good. This result is best explained by the theory that comparison stimuli retrieve the sample representation, but only in the behavioral context established by the R-cue. The present research supports the view that response-produced stimuli serve a contextual role in animal short-term memory.     

THE ART OF RETRIEVAL: Stoicism?

This essay argues that retrieving insights from the ancient Stoic philosophers for Christian ethics is much more difficult than is often assumed and, further, that the “ethics of retrieval” is itself something worth prolonged reflection. The central problem is that in their ancient sense both Christianity and Stoicism are practically dense patterns of reasoning and mutually incompatible forms of life. Coming to see this clearly requires the realization that the encounter between Stoicism and Christianity is a conflict of lived traditions. Precisely because we cannot simply extract Stoic insights from the lives in which they belong, the task of determining how Stoicism is useful for Christianity is exceptionally challenging. Indeed, doing justice to the Stoics has more to do with facing an alternative to Christianity than it does with appropriating insights for our own use. These points are developed in conversation with Elizabeth Agnew Cochran's recent article on the Stoic influence upon Jonathan Edwards.     

Selective deficits in episodic feeling of knowing in ageing: A novel use of the general knowledge task

Failure to recall an item from memory can be accompanied by the subjective experience that the item is known but currently unavailable for report. The feeling of knowing (FOK) task allows measurement of the predictive accuracy of this reflective judgement. Young and older adults were asked to provide answers to general knowledge questions both prior to and after learning, thus measuring both semantic and episodic memory for the items. FOK judgements were made at each stage for all unrecalled responses, providing a measure of predictive accuracy for semantic and episodic knowledge. Results demonstrated a selective effect of age on episodic FOK resolution, with older adults found to have impaired episodic FOK accuracy while semantic FOK accuracy remained intact. Although recall and recognition measures of episodic memory are equivalent between the two age groups, older adults may have been unable to access contextual details on which to base their FOK judgements. The results suggest that older adults are not able to accurately predict future recognition of unrecalled episodic information, and consequently may have difficulties in monitoring recently encoded memories.     

The cognitive interview: Its origins,empirical support,evaluation and practical implications

This paper provides a background to current research on the cognitive interview (CI), which is a set of cognitive retrieval techniques designed to facilitate memory search (for example, via reinstatement of contextual cues). One of the principal aims of this research is to identify and develop techniques which police investigators can themselves use. A series of studies were conducted at the University of California, Los Angeles, using police officers as interviewers and students, non-students and children as witnesses to realistic crimes. In all studies the CI elicited significantly more correct information with no apparent increase in errors or confabulations. The CI has been tested in a field study involving police officers in Florida. This paper will critically review this research, as well as more recent unpublished work including CI studies conducted in Germany and the UK. Some important modifications of the original CI procedure are described, and there is a theoretical discussion and explanation of the various components of the CI procedure. Finally, we will consider applications of the CI in clinical and organizational settings.     

内隐和外显记忆任务之间的实验性分离:编码程度和提取要求的作用

通过操纵编码程度(实验1)和提取要求(实验2)比较了内隐和外显记忆任务之间的操作变化.结果表明,编码时的语义和非语义加工之间存在着相互抑制的倾向;提取要求中更多意识成份的参与使先前情节中的语义成份得到更多的提取,而很少影响非语义成份的提取,编码程度和提取要求之间存在着相互作用.
