Memories of real-life decisions

Three studies investigated decision makers’ memory representations of choice alternatives in most important real-life decisions. In Study 1, each participant recalled the most important decision that she or he had ever made and rated to what degree a number of characteristics could describe the decisions. In Study 2, the participants were asked to think about an important decision that they had made during the last 7–10 days. In Study 3, the memory representations of decisions of a group of action-oriented participants were compared with those of a group of state-oriented participants (Kuhl, 1983). Characteristics related to standard decision theory, like consequences, values, and likelihood, had high ratings of applicability as well as affect/feeling. When testing the applicability of a circumplex model, the fuzzy-trace theory of memory, and differences between state- and action-oriented decision makers, we found (1) that there was no support for the circumplex model of emotions. Instead, an important decision problem was characterised by both positive and negative affect/emotion and thus, a bipolar mapping was found inadequate; (2) that a comparison of abstract and concrete aspects showed that the abstract characteristics scored higher, thereby supporting the fuzzy-trace theory; and (3) that the prediction that action-oriented participants would score higher than state-oriented participants on the characteristic of activity was not supported. However, state-oriented decision makers rated passivity higher than action-oriented decision makers for the important decision of leaving a partner. State-oriented decision makers used perceptual/cognitive scenario representations to a greater extent than action-oriented participants. Finally, it was stressed that in the development of decision theories it is essential to find theoretical representations as close as possible to how decision makers themselves represent the decisions. The method used in this contribution is focused on the role of memory in decision making and gives further insights into how important real-life decisions are represented by different decision makers.     

Memories of a 'decision-map': Recall of a real-life decision

First-year students in college who had participated in a study of college-decision-making 8 to 20 months earlier were asked to recall the criteria they had used and the alternatives they had considered in making the decision. They were also asked to describe the criteria they thought, in retrospect, that they ought to have used, and to rate their satisfaction with the decision-making process and its outcome. Two hundred and seven of the original 322 participants responded to a follow-up questionnaire through the mail. Participants recalled about half of the criteria they originally reported using, and about two-thirds of the schools they originally reported considering. Their recall of criteria was affected by their current view of teh criteria they should have used, providing a replication for previous findings. No gender or academic ability effects were found. Somewhat surprisingly, given existing literature, recall was unaffected by emotional responses to the decision, either those reported during the decision-making process or those reported retrospectively. Overall, the pattern of results suggests that memory is affected by a decision-maker's current cognitive framework of the decision, specifically, their retrospective view of how they ought to have made the decision. Moreover, memory is far from perfect, even for stimuli that the decision-maker generated her- or himself, and to which presumably, they gave significant amounts of thought.     

Memories of past episodes shape current intentions and decisions

This research tested the hypothesis that people's decisions and future plans are influenced by recently activated autobiographical memories. University students rated the overall quality of their college experiences. They were also asked to describe a specific memory of being either satisfied or dissatisfied with the university. Control participants did not describe a memory. After statistically controlling for pre-existing attitudes towards the university, students who recounted a positive memory expressed the strongest intentions to donate money to the university, attend a class reunion, and recommend the university to others, and they were more likely than controls to specify that an actual donation be made to the university rather than to another charity. Emotional intensity of positive memories predicted future plans and donation decisions. Students who recounted a negative memory also tended to favour the university in their actual donation decisions compared to controls. Prompting the recall of emotional memories may be an effective way to influence intentions and decisions.     

Remembering the best and worst of times: Memories for extreme outcomes bias risky decisions

When making decisions on the basis of past experiences, people must rely on their memories. Human memory has many well-known biases, including the tendency to better remember highly salient events. We propose an extreme-outcome rule, whereby this memory bias leads people to overweight the largest gains and largest losses, leading to more risk seeking for relative gains than for relative losses. To test this rule, in two experiments, people repeatedly chose between fixed and risky options, where the risky option led equiprobably to more or less than did the fixed option. As was predicted, people were more risk seeking for relative gains than for relative losses. In subsequent memory tests, people tended to recall the extreme outcome first and also judged the extreme outcome as having occurred more frequently. Across individuals, risk preferences in the risky-choice task correlated with these memory biases. This extreme-outcome rule presents a novel mechanism through which memory influences decision making.

Borrowing Personal Memories

The present investigation documents memory borrowing in college‐age students, defined as the telling of others' autobiographical stories as if they are one's own. In both pilot and online surveys, most undergraduates admit to borrowing personal stories from others or using details from others' experiences to embellish their own retellings. These behaviors appear primarily motivated by a desire to permanently incorporate others' experiences into one's own autobiographical record (appropriation), but other reasons include to temporarily create a more coherent or engaging conversational exchange (social connection), simplify conveying somebody else's interesting experience (convenience), or make oneself look good (status enhancement). A substantial percentage of respondents expressed uncertainty as to whether an autobiographical experience actually belonged to them or to someone else, and most respondents have confronted somebody over ownership of a particular story. Documenting memory borrowing is important as the behavior has potential consequences for the creation of false memories. Copyright © 2015 John Wiley & Sons, Ltd.     

Suppressing Unwanted Memories

ABSTRACT— When reminded of something we would prefer not to think about, we often try to exclude the unwanted memory from awareness. Recent research indicates that people control unwanted memories by stopping memory retrieval, using mechanisms similar to those used to stop reflexive motor responses. Controlling unwanted memories is implemented by the lateral prefrontal cortex, which acts to reduce activity in the hippocampus, thereby impairing retention of those memories. Individual differences in the efficacy of these systems may underlie variation in how well people control intrusive memories and adapt in the aftermath of trauma. This research supports the existence of an active forgetting process and establishes a neurocognitive model for inquiry into motivated forgetting.     

Involuntary Autobiographical Memories

Results from a diary study of involuntary memories are presented (14 subjects; 7 males, 7 females, average age 23 years). Virtually all of the recorded memories had identifiable cues. Memory access was biased towards (a) mood-congruent (b) recent and (c) distinctive (unusual) events. The memories were most frequently rated as emotionally positive and prior rehearsal was rated low. Also, the memories were found to influence current mood consonant with the emotional valence of the memories. Stressful and repetitive involuntary recollections—as they are observed in clinical settings subsequent to traumatic events—may be viewed as a malignant effect of normal mechanisms of involuntary memories.     

Distant Memories: A Prospective Study of Vantage Point of Trauma Memories

ABSTRACT— Adopting an observer perspective to recall trauma memories may function as a form of avoidance that maintains posttraumatic stress disorder (PTSD). We conducted a prospective study to analyze the relationship between memory vantage point and PTSD symptoms. Participants ( N = 947) identified the vantage point of their trauma memory and reported PTSD symptoms within 4 weeks of the trauma; 730 participants repeated this process 12 months later. Initially recalling the trauma from an observer vantage point was related to more severe PTSD symptoms at that time and 12 months later. Shifting from a field to an observer perspective a year after trauma was associated with greater PTSD severity at 12 months. These results suggest that remembering trauma from an observer vantage point is related to both immediate and ongoing PTSD symptoms.     

Memories of Donald Winnicott

Barbara Dockar-Drysdale, founder and original therapeutic adviser to the Mulberry Bush School, is now in her eighties, and living in retirement. Her writings make frequent reference to her indebtedness to Winnicott, whom she used to meet monthly over the last seventeen years of his life to discuss their ideas and work. Winnicott wrote of her: ‘Here was someone who knew’.     

Neural Representations of Nondeclarative Memories

ABSTRACT— Nondeclarative learning refers to abilities characterized by a lack of awareness of what has been learned and an independence from medial temporal lobe structures that support conscious memories of facts and events. Neuroimaging approaches have been used extensively in two domains of nondeclarative learning—priming and skill learning—to investigate the neural substrates supporting performance. Recent neuroimaging studies have attempted to understand what is being learned in different tasks in order to inform psychological theories of nondeclarative memory. For example, priming may be considered a form of perceptual learning or a form of stimulus–response learning, and correlations between performance and activation patterns in different regions may suggest the nature of the brain changes that support behavior. The attainment of expertise in a skill has been characterized as greater efficiency of processing in the same neural structures that support novice performance or, alternatively, as the recruitment of additional regions. Current research suggests that, within the domains of priming and skill learning, there is much heterogeneity in the underlying brain representations and psychological theories will need to account for these variations.     

Metastable attunement and real-life skilled behavior

In everyday situations, and particularly in some sport and working contexts, humans face an inherently unpredictable and uncertain environment. All sorts of unpredictable and unexpected things happen but typically people are able to skillfully adapt. In this paper, we address two key questions in cognitive science. First, how is an agent able to bring its previously learned skill to bear on a novel situation? Second, how can an agent be both sensitive to the particularity of a given situation, while remaining flexibly poised for many other possibilities for action? We will argue that both the sensitivity to novel situations and the sensitivity to a multiplicity of action possibilities are enabled by the property of skilled agency that we will call metastable attunement. We characterize a skilled agent’s flexible interactions with a dynamically changing environment in terms of metastable dynamics in agent-environment systems. What we find in metastability is the realization of two competing tendencies: the tendency of the agent to express their intrinsic dynamics and the tendency to search for new possibilities. Metastably attuned agents are ready to engage with a multiplicity of affordances, allowing for a balance between stability and flexibility. On the one hand, agents are able to exploit affordances they are attuned to, while at the same time being ready to flexibly explore for other affordances. Metastable attunement allows agents to smoothly transition between these possible configurations so as to adapt their behaviour to what the particular situation requires. We go on to describe the role metastability plays in learning of new skills, and in skilful behaviour more generally. Finally, drawing upon work in art, architecture and sports science, we develop a number of perspectives on how to investigate metastable attunement in real life situations.

     

Memories of Punishment for Cursing

Researchers do not know how parents respond to children’s cursing or what effect parents’ responses have on children later in life. We conducted two studies with college students: a content analysis of 47 personal narratives of childhood cursing and an item analysis of a 70-item questionnaire administered to 211 students. Contrary to gender differences found in previous narrative and cursing research, men’s narratives were as emotional as women’s narratives, and women used as many curse words as men. The two studies confirm that cursing is a common childhood problem and that mothers play a more prominent disciplinary role than fathers do. Parents respond with physical forms of punishment (e.g., spanking) but not as frequently as verbal reprimands. Our data are the first to document the prevalence of washing children’s mouths with soap. College students have vivid memories of punishment; however 94% reported that they continue to curse.
