情绪影响错误记忆认知机制的年龄差异

以情绪性的类别图片为实验材料,使用改进后的简化联合再认范式,结合多项式加工树建模的统计手段,对28名老年人(67.95±4.70岁)和29名年轻人(22.60±2.74岁)情绪错误记忆的产生机制进行考察。结果发现,在行为层面,消极情绪增加年轻人和老年人的错误"记得",而积极情绪只增加老年人的错误"记得",老年人错误记忆的积极效应体现在更多地报告自己生动鲜明地"记得"未曾发生过的积极事件。在认知机制层面,虚假回想是导致老年人错误记忆出现积极效应的关键认知过程。相比年轻人,积极情绪会独特地增加老年人的虚假回想,进而增加错误"记得"的发生概率。     

Tricks of Memory

Remembering an episode from even the recent past may involve a blend of fiction and fact. We discuss a straight-forward laboratory paradigm that is proving useful in the study of false memories of simple episodes. In this paradigm, subjects study lists of 15 related words ( bed, rest, awake ...) that are all related to a critical word that is not presented ( sleep ). Later, subjects recall and recognize the critical missing word with about the same probability that they remember words from the list. This memory illusion is resistant to people's attempts to avoid it. We argue that similar memory errors are commonplace and are a natural outcome of an intelligent cognitive system, which makes inferences about incoming information. Therefore, memory illusions, like perceptual illusions, are a consequence of normal human information processing and offer a window for examining basic cognitive processes.     

Using dual-criteria methods to supplement visual inspection: Replication and extension

The dual-criteria and conservative dual-criteria methods effectively supplement visual analysis with both simulated and published datasets. However, extant research evaluating the probability of observing false positive outcomes with published data may be affected by case selection bias and publication bias. Thus, the probability of obtaining false positive outcomes using these methods with data collected in the course of clinical care is unknown. We extracted baseline data from clinical datasets using a consecutive controlled case-series design and calculated the proportion of false positive outcomes for baseline phases of various lengths. Results replicated previous findings from Lanovaz, Huxley, and Dufour (2017), as the proportion of false positive outcomes generally decreased as the number of points in Phase B (but not Phase A) increased using both methods. Extending these findings, results also revealed differences in the rate of false positive outcomes across different types of baselines.     

Personalities in the crowd: Those who would escalate a sports riot

A series of four studies was conducted at ice hockey games with a view to establishing the correlates of spectator's self-reported reasons for attending and their propensity for involvement in crowd disturbances. Spectators attending for the reason of “I like to watch the fights” and those most likely to join in a fight if one were to break out in the stands were young, single males. Ratings on the dependent variables were further related to individual differences measures of assaultiveness, psychopathy, self-esteem, and public self-consciousness. Anomy was unrelated to either dependent measure. Support for the false consensus effect was additionally forthcoming. © 1995 Wiley-Liss, Inc.     

Generating consensus priority interval vectors for group decision‐making in the AHP

Many practical and important decision‐making problems are complicated by at least two factors: (1) the qualitative/subjective nature of some criteria often results in uncertainty in the individual ratings; and (2) group decision‐making is involved and some means of aggregating individual ratings is required. Traditionally, both individual and group priorities have been represented as point estimates, but this approach presents severe limitations for accommodating imprecision in the decision‐making process. This paper examines the group decision‐making problem in the context where priorities are represented as numeric intervals. A set of techniques that could be used at some of the phases of an analytic hierarchy process (AHP)‐based group decision‐making process, which has the objective of generating a ‘consensus’ priority that represents the group's opinion with regards to the relative importance of a set of N objects (e.g. criteria, alternatives), is presented.

Weight-based discrimination,body dissatisfaction and emotional eating: The role of perceived social consensus

Objective: Discrimination can have a negative impact on psychological well-being, attitudes and behaviour. This research evaluates the impact of experiences of weight-based discrimination upon emotional eating and body dissatisfaction, and also explores whether people's beliefs about an ingroup's social consensus concerning how favourably overweight people are regarded can moderate the relationship between experiences of discrimination and negative eating and weight-related cognitions and behaviours.

Research methods and procedures: 197 undergraduate students completed measures about their experiences of weight-based discrimination, emotional eating and body dissatisfaction. Participants also reported their beliefs concerning an ingroup's attitude towards overweight people.

Results: Recollections of weight-based discrimination significantly contributed to emotional eating and body dissatisfaction. However, the relationships between experiencing discrimination and body dissatisfaction and emotional eating were weakest amongst participants who believed that the ingroup held a positive attitude towards overweight people.

Discussion: Beliefs about ingroup social consensus concerning overweight people can influence the relationships between weight-based discrimination and emotional eating and body dissatisfaction. Changing group perceptions to perceive it to be unacceptable to discriminate against overweight people may help to protect victims of discrimination against the negative consequences of weight-based stigma.     

Spatial Conceptions in Chinese and Canadian Children

Four-, five-, and six-year-old Chinese and Canadian boys and girls were presented a series of 11 graphic models and were asked to draw them. Supporting Piaget's theory, the data indicated that drawing performance on the topological dimension was better than the performance on the Euclidean dimension, and that there were neither gender nor cultural differences in performance. The research offers strong support for a main effect of biological or maturational factors as the foundation for the developmental influences in the acquisition of spatial conceptions.     

Beliefs Don't Always Persevere: How Political Figures Are Punished When Positive Information about Them Is Discredited

Recent research has extended the belief‐perseverance paradigm to the political realm, showing that negative information about political figures has a persistent effect on political opinions even after it has been discredited. However, little is known about the effects of false positive information about political figures. In three experiments, we find that discrediting positive information generates a “punishment effect” that is inconsistent with the previous literature on belief perseverance. We argue people attempt to adjust for the perceived influence of the false claim when the information is discredited. In this case, when trying to account for the effects of discredited positive information about a politician, people overestimate how much correction is needed and thus end up with a more negative opinion. (By contrast, people underestimate how much correction is needed to adjust for false negative information, leading to belief perseverance.) These results suggest that bogus credit claiming or other positive misinformation can have severe repercussions for politicians.     

Psychoanalysis is a two‐way street

The paper discusses psychoanalysis as a mutual exchange between the analyst and analysand. A number of questions are raised: What was Ferenczi's and the early psychoanalysts' contribution to the interpersonal relational dynamics of psychoanalytic treatment? Why did countertransference become an indispensable tool in relationship‐based psychoanalysis? Why is the transference‐countertransference dynamic seen as a special dialogue between the analyst and analysand? What was Ferenczi's paradigm shift in the trauma theory? How did he combine the object relation approach with Freud's original trauma theory? The paper illustrates through some case study vignettes the intersubjective and intrapsychic dynamic in the process of traumatization. We can look at countertransference as an indicator of the patient's basic interpersonal experiences and traumas. Finally the paper discusses countertransference in the light of attachment theory, connecting the early initiatives of inter‐relational approaches in psychoanalysis with recent research.     

Reinstatement of odour context cues veridical memories but not false memories

ABSTRACT

The sense of smell has made a recent return to the forefront of research on episodic memory. Odour context cues can reactivate recently encoded memories during sleep-dependent memory consolidation [e.g., Rasch, B., Buchel, C., Gais, S., & Born, J. (2007). Odor cues during slow-wave sleep prompt declarative memory consolidation. Science, 315, 1426–1429], and reinstating the odour experienced during encoding at test results in superior recall and recognition [e.g., Isarida, T., Sakai, T., Kubota, T., Koga, M., Katayama, Y., & Isarida, T. K. (2014). Odor-context effects in free recall after a short retention interval: A new methodology for controlling adaptation. Memory & Cognition, 42, 421–433]. However, whether the impact of odour cues is restricted to the specific memories studied in the presence of the odour, or whether reinstating the odour also cues unstudied memories that are semantically related to the studied memories (i.e., false memories) is unknown. We used the Deese-Roediger-McDermott false memory paradigm to quantify the impact of odour cues on both veridical memory and false memory. Reinstating the odour presented during the study of the DRM word lists at the test phase resulted in better free recall of the studied words, but had no statistically significant impact on the number of false memories produced. We argue that odour cues influence recall of the memories they co-occurred with during study but potentially not semantically related memories.
