Research shows that memory may be changed during storage, processing and retrieval, due to schema processing. Relevant examples related to studying the nature of reconstructive memory could be but are not limited to: • confabulation—a memory based on a fabricated, distorted or misinterpreted memory often believed to be true in spite of contradictory evidence • schema processing—memory processing based on prior knowledge in the form of schemas that could result in distortion • false memories—recalling an event that never happened and believing it to be true.

  • Recall and Recognition on Minimalism

Reprints and Permission: [email protected] Published by the Hungarian Communication A Replication of the Case Study Studies Association on the Apple Logo DOI: 10.17646/KOME.2017.24 Ioana Iancu1 and Bogdan Iancu2 1 Babes-Bolyai University, Cluj-Napoca, ROMANIA 2 Technical University of Cluj-Napoca, ROMANIA Abstract: The present research aims to better understand the impact of brand exposure and brand perception on logo recall and recognition. Building off of prior work that has examined surprising impairments in visual memory for the Apple logo (Blake, Nazarian and Castel, 2015), a comparative analysis is developed by comparing computer science and social science becoming specialists. The Apple logo is used as a case study due to its minimalism. The data reveal that only a small amount of the subjects can recall and recognize the Apple logo correctly. The recognition phase, in comparison with the recalling one, seems to be an easier task for the subjects. However, although the stylized features of the logo are often overlooked, each subject manages to recognize a large amount of details of the logo. Contrary to expectations, regardless of being a man or a woman, owning an Apple device, or developing a very positive emotional attachment to the brand are not significant variables that can determine a higher level of recall and recognition. Nevertheless, having a strong background in the technological domain can increase the probability of paying much attention to the details of a technical brand.

Aristotle and Plato wrote about memory in ways that seem surprisingly modern even today, although of course in the wisdom of hindsight many of their claims are off the mark. For example, Aristotle thought that the heart was the seat of learning, memory, and intelligence and that the brain existed to cool the heart.

  • Generative Memory
    Philosophical Psychology Vol. 24, No. 3, June 2011, 323–342 Generative memory Kourken Michaelian This paper explores the implications of the psychology of constructive memory for philosophical theories of the metaphysics of memory and for a central question in the epistemology of memory. I first develop a general interpretation of the psychology of constructive memory. I then argue, on the basis of this interpretation, for an updated version of Martin and Deutscher’s influential causal theory of memory. I conclude by sketching the implications of this updated theory for the question of memory’s status as a generative epistemic source. Keywords: Causal Theory of Memory; Constructive Memory; Epistemology of Memory There has been relatively little philosophical work in recent years on the metaphysics of memory (the nature of memory in general). This is presumably because most philosophers have assumed that something close to Martin and Deutscher’s (1966) causal theory of memory is right. Bernecker’s (2008) recent work, e.g., the first book-length work on the metaphysics of memory to appear in some years, defends a causal theory of memory very much in the spirit of Martin and Deutscher’s; and Downloaded By: [Michaelian, Kourken] At: 07:07 10 June 2011 there have been no very recent attacks on the theory. While I, too, ultimately want to defend a theory in the spirit of the classical causal theory, I also maintain that our confidence in the causal theory has been to a certain extent unfounded, for the psychology of constructive memory poses a significant challenge to the causal theory of memory, and few philosophers concerned with the metaphysics of memory have so far taken empirical work on the constructive nature of memory into account.

  • 2000 Tversky Marsh Biased Retellings of Events Yield Biased
    Cognitive Psychology 40, 1±38 (2000) doi:10.1006/cogp.1999.0720, available online at http://www.idealibrary.com on Biased Retellings of Events Yield Biased Memories Barbara Tversky and Elizabeth J. Marsh Stanford University When people retell events, they take different perspectives for different audiences and purposes. In four experiments, we examined the effects of this postevent reorga- nization of events on memory for the original events. In each experiment, partici- pants read a story, wrote a biased letter about one of the story characters, and later remembered the original story. Participants' letters contained more story details and more elaborations relevant to the purpose of their retellings. More importantly, the letter perspective affected the amount of information recalled (Experiments 1, 3, and 4) and the direction of the errors in recall (Experiments 1 and 3) and recognition (Experiment 2). Selective rehearsal plays an important role in these bias effects: retelling involves selectively retrieving and using story information, with conse- quent differences in memory. However, biased memory occurred even when the biased letters contained little, if any, speci®c information (Experiment 4) or con- tained the same amount and kinds of story information as a neutral control condition (Experiment 3). Biased memory is a consequence of the reorganizing schema guid- ing the retelling perspective, in addition to the effects of rehearsing speci®c informa- tion in retelling. 2000 Academic Press Key Words: retellings; memory; schemas. When things happen to us, we talk about them. Events do not just happen in words, but that is our primary means of conveying them.

  • How and When Advertising Can Influence Memory for Consumer
    How and When Advertising Can Influence Memory for Consumer Experience Kathryn A. Braun-LaTour, University of Nevada Las Vegas Michael S. LaTour, University of Nevada Las Vegas Jacqueline E. Pickrell, University of Washington Elizabeth F. Loftus, University of California-Irvine Recent "paradigm shifting" research in consumer behavior dealing with reconstructive memory processes suggests that advertising can exert a powerful retroactive effect on how consumers remember their past experiences with a product. Building on this stream of research, we have executed three studies that incorporate the use of false cues with the aim of shedding new light on how post-experience advertising exerts influence on recollection. Our first experiment investigates an important but yet unexplored issue to advertisers who are perhaps reticent about embracing this paradigm: Does the false cue fundamentally change how consumers process information? After finding that when the false information goes undetected it is processed in a similar manner as more "truthful" cues, we use this paradigm to shed light on the pictorial versus verbal information debate in advertising. We discuss the implications of our findings for those interested in managing consumer experience and for advertising researchers seeking indirect measures of the influence of advertising. Remember your childhood visit to Disneyland?—Cinderella's castle glistening, the cartoon characters laughing, grouping for photos, the many rides with their height requirements, the smells of freshly cooked food, and Bugs Bunny shaking your hand? As you bring that experience to mind, you may have the feeling you are reliving it, seeing your childhood pass through your mind's eye, much like reviewing a video-tape.

However, the study of memory has long been neglected in English Studies. Therefore, communicators lack strategies for enhancing documents’ memorableness and an ethical framework for assessing (un)memorable documents and composing processes.

  • Memory Impairment in the Weapon Focus Effect
    Memory & Cognition 2009, 37 (3), 326-335 doi:10.3758/MC.37.3.326 Memory impairment in the weapon focus effect JO SAUNDERS Swansea University, Swansea, Wales Two experiments are reported in which postevent source of misinformation was manipulated within weapon- present and weapon-absent scenarios. Participants viewed slides depicting either a weapon or a newspaper event and then received either incomplete questioning or a narrative. Both postevent sources contained misleading information about a central and peripheral detail concerning either the weapon or the newspaper scenario. With a modified test in Experiment 1, questioning was found to increase misinformation effects concerning the central item, as compared with a narrative, and more misinformation effects were found for the weapon-peripheral than for the newspaper-peripheral item. In Experiment 2, the participants were more likely to claim to have seen contra- dictory and additive misinformation about the central item in the slides following questioning, and more contra- dictory and additive misinformation effects occurred for the weapon-peripheral than for the newspaper-peripheral item. The findings are considered in terms of the effects of both postevent and encoding factors on memory. Many factors influence the direction of a criminal in- time, we do not expect someone to draw a weapon when vestigation. Physical evidence, such as fingerprints or we ourselves are visiting the bank.
