Voters, Emotions, and Memory

In this paper we argue that emotional response to information encountered in campaigns has implications for the likelihood of remembering that information at the time of the vote. Most voting models are built on what voters remember—whether it is the placement of candidates on issues, or opened ended responses to prompts. That recall of memory is biased is well-known, but the extent to which those biases are driven by affective response to candidate information has not been studied. Using dynamic process tracing, we examine voters' emotional responses, information search, and candidate evaluations during a simulated presidential primary campaign. By manipulating anxiety and the amount of incongruent information that voters encounter, we can detect the direct influence of affect in information processing. We find evidence that voters are more likely to remember information that generates any affective reaction as opposed to information for which the subjects report no emotional response. However, we find little evidence that anxiety has a special role, compared to enthusiasm or anger, in increasing the likelihood that an individual item is remembered. This challenges a primary contention of the theory of Affective Intelligence that anxiety leads to more memories for campaign information.     

Experiencing and regulating sadness: Physiological and cognitive effects

No prior study has examined the two most prominent response-focused regulation strategies (suppression and exaggeration) using a within-subjects design. Utilizing this design allows for a direct comparison of physiological patterns and cognitive impairment associated with such efforts. One hundred and nine participants were asked to view a series of three films, each preceded by a 10-second instructional slide which indicated the regulation strategy they were to perform (natural-watch, exaggerate, or suppress). Exaggeration was associated with increased sympathetic activation as indicated by an increase in galvanic skin conductance level (GSL) and shortened pre-ejection period (PEP). Suppression, much like the natural-watch condition, was associated with greater sympathetic withdrawal (i.e., decreased GSL, longer PEP). Both suppression and exaggeration led to reduced memory for the emotional movie, with exaggeration causing more impairment than suppression. Results suggest that exaggeration and suppression not only have very different behavioral manifestations, but physiological outcomes as well when utilized during a sad context.     

Global Model Analysis of Cognitive Variability

Residual fluctuations produced in typical experimental methodologies are examined as correlated noises. The effective range of the correlations was assessed by determining whether the decay over look-back time is better described as a power law or exponential. Both of these decay laws contain free parameters and it is argued that it is not possible to distinguish their models on the basis of simple measures of goodness-of-fit. Global analyses that evaluate models on the basis of how well they generalize are conducted. The models are examined in terms of three constructs that all bear on generalization: cross-validity, flexibility, and representativeness. Quantitative assessment of a large ensemble of data suggests that the correlations decay over time as a power law. The conclusion is that human residual fluctuation is a correlated fractal.     

Specialization effect and its influence on memory and problem solving in expert chess players

Expert chess players, specialized in different openings, recalled positions and solved problems within and outside their area of specialization. While their general expertise was at a similar level, players performed better with stimuli from their area of specialization. The effect of specialization on both recall and problem solving was strong enough to override general expertise—players remembering positions and solving problems from their area of specialization performed at around the level of players 1 standard deviation (SD) above them in general skill. Their problem-solving strategy also changed depending on whether the problem was within their area of specialization. When it was, they searched more in depth and less in breadth; with problems outside their area of specialization, the reverse. The knowledge that comes from familiarity with a problem area is more important than general purpose strategies in determining how an expert will tackle it. These results demonstrate the link in experts between problem solving and memory of specific experiences and indicate that the search for context-independent general purpose problem-solving strategies to teach to future experts is unlikely to be successful.     

Verbal predicates foster conscious recollection but not familiarity of a task-irrelevant perceptual feature – An ERP study

Research on the effects of perceptual manipulations on recognition memory has suggested that (a) recollection is selectively influenced by task-relevant information and (b) familiarity can be considered perceptually specific. The present experiment tested divergent assumptions that (a) perceptual features can influence conscious object recollection via verbal code despite being task-irrelevant and that (b) perceptual features do not influence object familiarity if study is verbal-conceptual. At study, subjects named objects and their presentation colour; this was followed by an old/new object recognition test. Event-related potentials (ERP) showed that a study-test manipulation of colour impacted selectively on the ERP effect associated with recollection, while a size manipulation showed no effect. It is concluded that (a) verbal predicates generated at study are potent episodic memory agents that modulate recollection even if the recovered feature information is task-irrelevant and (b) commonly found perceptual match effects on familiarity critically depend on perceptual processing at study.     

Memory issues pertaining to social marketing messages about behavior enactment versus non-enactment

This article examines efficiency issues pertaining to social marketing messages about behavior enactment (e.g., smoker) vs. non-enactment (e.g., nonsmoker). Building on a wealth of psycholinguistics research, we posit that underlying differences in the processing and storage of word concepts with affixal negations affect learning and memory for these concepts (i.e., associations with non-enactment concepts will be harder to learn and remember than associations with enactment concepts). Two experiments support our predictions, suggesting that messages about enactment will demonstrate superior efficiency. Implications of study findings are discussed in terms of possibilities for improving the efficiency of social marketing messages about non-enactment.     

陈述性记忆存储和巩固的神经机制

综述了陈述性记忆形成和巩固的神经机制,并对经典模型进行了修正和拓展。主要观点是：陈述性记忆的存储和巩固依赖于新皮层不同脑区之间建立新的联系,内侧颞叶在这一过程中起着重要作用;当陈述性记忆完全巩固后,信息的存储和提取完全依赖于新皮质;一个完整的陈述性记忆的信息被分别存储在解剖上分离的语义记忆与情节记忆存储系统内     

急性心理应激影响记忆效果：心理韧性的调节作用

研究选取56名大学生被试,通过特里尔社会应激测验、记忆和心理韧性测验来探究急性心理应激对大学生记忆效果的影响,以及心理韧性在二者关系中的调节作用。结果表明相对于非应激组,应激组大学生的整体记忆成绩更差,且应激组中的高应激反应大学生的记忆成绩比低应激反应者的记忆成绩更差;心理韧性可以调节应激反应与记忆成绩之间的关系,表现为高心理韧性者的记忆成绩显著好于低心理韧性者。研究进一步从认知加工资源分配与再分配的视角讨论了心理应激、心理韧性与记忆功能三者间的关系与启示。     

Dissociative effects of elaboration on memory of enacted and non-enacted events: A case of a negative effect

One experiment compared the effect of elaboration on enacted and non-enacted events. The commands were either presented in a basic form (e.g., "wave your hands") or in an enriched form. The commands were enriched by adding statements to the commands of how to perform the actions (e.g., "wave your hands as a conductor"). Free- and cued-recall data showed elaboration to have a dissociative effect on enacted and non-enacted events. Memory for the non-enacted events benefited from enrichment, whereas simple enacted events were remembered to a higher extent than complex enacted events. Lack of benefit from elaboration on memory of enacted events is suggested to be due to enactment leading to a sufficient degree of item-specific processing, and a negative effect of elaboration is suggested to occur when the way of manipulating item complexity decreases the familiarity of the actions. Familiarity ratings of the items by two independent groups of subjects supported this interpretation.
