老年人错误记忆的情绪效价和时间效应

基于信号检测论的框架, 考察不同的情绪效价以及时间间隔如何交互影响老年人在图片再认任务中的辨别力(d′)和判断标准(β), 进而影响其错误记忆。以21名老年人(女性14名)为被试, 平均年龄67.17 ± 5.03岁。根据中国老年人对国际情绪图片库(International Affective Picture System, IAPS)中图片评定的情绪参数, 选出积极、消极和中性图片各60张作为学习材料。另选积极、消极和中性图片各30张作为每次再认测验的干扰材料, 并且两次再认测验的干扰材料不同。短时间隔条件让老年人在图片记忆编码半个小时后完成对图片的再认测验; 长时间隔条件则为在三周后完成对图片的再认测验。结果发现: 1)在短时间隔条件下, β和d′共同影响虚报率; 而在长时间隔条件下, 只有β影响虚报率, d′不影响虚报率; 2)无论是在短时还是长时间隔条件下, 积极图片与消极图片的判别力d′都没有显著差别; 3)在短时间隔条件下, 老年人对消极图片的β更低、虚报率更高; 在长时间隔条件下, 老年人对积极图片的β更低、虚报率更高。研究结果表明: 老年人的错误记忆受判别力d′和判断标准β的影响。情绪效价通过作用于老年人的反应倾向(判断标准β)、而非记忆质量(判别力d′)来影响其错误记忆。时间间隔可以调节情绪效价对老年人判断标准β和错误记忆的作用, 使之随时间发生反转。老年人的“积极效应”在错误记忆中可能表现为随着时间的流逝, 老年人更愿意将积极信息报告为经历或学习过的信息。     

Effects of valence and framing in decision making II: Estimating subjective weighting1

Abstract: In comparison between choice options, judgments of “How much better is a preferred option?” and “How much worse is a less preferred option?” may differ in their magnitudes. Such discrepancies are called “valence effects.” Previously, Yamagishi and Miyamoto (1996) observed systematic positive valence effects (“Better” exceeding “Worse”) in the domain of gains and systematic negative valence effects (“Worse” exceeding “Better”) in the domain of losses. The current experiment used the directions of valence effects as a tool to assess the decision maker's interpretation of choice tasks under the “framing effect” ( Tversky & Kahneman, 1986 ). Preferences under the framing effect switch from certain options in the domain of gains to uncertain options in the domain of losses. This study examined whether preferences for certain options were associated with positive valence effects, whereas preferences for uncertain options were associated with negative valence effects. Moreover, conditions under which preference reversals under the framing manipulations ceased to occur were examined. The effects of valence showed that framing effects ceased to occur when decision makers maintained consistent task interpretations as pertaining to gains or to losses. Most importantly, the pattern of subjective weighting under the valence effects was consistent with previous explanation of valence effects ( Yamagishi & Miyamoto, 1996 ). Possibilities for extending the current findings to understanding related psychological phenomena are discussed.     

Exercise based interventions for alcohol use disorder: A comment on motivational aspects of participation

Exercise based treatment for alcohol use disorders have shown an impact on mental health (e.g., depression or anxiety), and alcohol outcomes (e.g., craving or abstinence). However, there is a lack of information on the role of motivational aspects of participation in the process of designing exercise interventions for alcohol use disorder. This study aims to examine: (1) whether motivational aspects are taken into account when the type and delivery method of exercise interventions are chosen; (2) whether motivational aspects are taken into account post intervention; and (3) whether there are different traditions regarding payment for participants. A systematic search was conducted to identify eligible studies in order to investigate the impact of motivational aspects including payment for participation. Twelve samples including ten to 620 participants were investigated. Participants were predominantly male and in their 40s, ranging from 20 to 69 years. Aerobic exercise (running, walking, fitness) either in a group or individual condition is the most frequently used exercise form. Two studies included ball games or cycling, while only one study offered the opportunity to choose between a wide range of sports. Motivational aspects are mentioned explicitly in half of the studies, mostly with regard to adherence to participation and social integration as the reason for using a group condition. Achievement is mentioned in two studies but not explicitly with regard to planning the intervention design. Five studies include payment for participation in exercise. Findings of the present study identify that motivational aspects for participation are rarely involved in the planning of an exercise intervention. With regard to the specific psychosocial vulnerability of an alcohol use disorder population, this should be an important aspect of further research studies.     

Seasonal Variations in Color Preference

We investigated how color preferences vary according to season and whether those changes could be explained by the ecological valence theory (EVT). To do so, we assessed the same participants’ preferences for the same colors during fall, winter, spring, and summer in the northeastern United States, where there are large seasonal changes in environmental colors. Seasonal differences were most pronounced between fall and the other three seasons. Participants liked fall‐associated dark‐warm colors—for example, dark‐red, dark‐orange (brown), dark‐yellow (olive), and dark‐chartreuse—more during fall than other seasons. The EVT could explain these changes with a modified version of Palmer and Schloss’ (2010) weighted affective valence estimate (WAVE) procedure that added an activation term to the WAVE equation. The results indicate that color preferences change according to season, as color‐associated objects become more/less activated in the observer. These seasonal changes in color preferences could not be characterized by overall shifts in weights along cone‐contrast axes.     

Emotion and false memory: How goal-irrelevance can be relevant for what people remember

Elaborating on misleading information concerning emotional events can lead people to form false memories. The present experiment compared participants’ susceptibility to false memories when they elaborated on information associated with positive versus negative emotion and pregoal versus postgoal emotion. Pregoal emotion reflects appraisals that goal attainment or failure is anticipated but has not yet occurred (e.g., hope and fear). Postgoal emotion reflects appraisals that goal attainment or failure has already occurred (e.g., happiness and devastation). Participants watched a slideshow depicting an interaction between a couple and were asked to empathise with the protagonist's feelings of hope (positive pregoal), happiness (positive postgoal), fear (negative pregoal), or devastation (negative postgoal); in control conditions, no emotion was mentioned. Participants were then asked to reflect on details of the interaction that had occurred (true) or had not occurred (false), and that were relevant or irrelevant to the protagonist's goal. Irrespective of emotional valence, participants in the pregoal conditions were more susceptible to false memories concerning goal-irrelevant details than were participants in the other conditions. These findings support the view that pregoal emotions narrow attention to information relevant to goal pursuit, increasing susceptibility to false memories for irrelevant information.

Oral kinematics: examining the role of edibility and valence in the in-out effect

Previous research has revealed a stable preference for words with inward consonantal-articulation patterns (from the front to the back of the mouth; e.g. BENOKA), over outward-words (from the back to the front; e.g. KENOBA). Following the oral approach-avoidance account suggesting that the in–out effect is due to the resemblance between consonantal-articulations patterns and ingestion/expectoration, recent findings have shown that when judging inward-outward names for objects with particular oral functions, valence did not modulate the effect while the oral function did. To replicate and examine further the role of edibility and valence in shaping the in–out effect, we asked participants (N?=?545) to rate inward and outward names for edible and non-edible products while controlling for valence. Results revealed that the motor-to-affect link was only observed for edible products, regardless of valence.     

Mood and Information Processing: When Happy and Sad Look the Same

Two studies were conducted to demonstrate that sad and happy moods can cause individuals to be similarly sensitive to the valence of observed stimuli with regard to how effortfully such stimuli are processed. In Study 1, individuals in whom a sad or happy mood had been induced unitized a behavior sequence less finely when its contents were neutral as opposed to positive. Individuals in a neutral mood state maintained a comparable level of unitization regardless of the valence of the behavior sequence. In Study 2, individuals in whom a sad or a happy mood had been induced processed the arguments in a persuasive communication more extensively when its contents were affectively uplifting rather than depressing. Sad individuals showed this pattern only if no prior affective expectation was provided. Taken together, these studies may fit with the notion that under certain conditions sad and happy individuals similarly decrease the amount of information processed from a neutral (Study 1) or depressing (Study 2), relative to a positive, stimulus.     

Semantic category effect and emotional valence in female university students

The semantic category effect represents a category dissociation between biological and nonbiological objects in picture naming. The aim of this preliminary study was to further examine this phenomenon, and to explore the possible association between the effect and subjective emotional valence for the named objects. Using a speeded picture naming task, vocal reaction times for 45 items were divided into four categories based on emotional valence rating and semantic category, and examined in 36 female university students. Analyses of the data indicated an "animate/inanimate" category dissociation favouring animate objects, in tandem with a potential relationship between subjective emotional valence and semantic processing underlying picture naming.     

Difficult Patients in Group Analysis: The Personification of (ba) I:A/M

Following a discussion of the treatment of difficult patients in group analysis, two theories are proposed concerning a fourth basic assumption in the unconscious life of groups, called Incohesion: Aggregation/Massification or (ba) I:A/M and the personification of basic assumption processes, in particular that of (ba) I:A/M by difficult patients. These theories are illustrated with clinical data. Special attention is given to crustacean and amoeboid forms of encapsulation as a defence against the fear of annihilation within the context of the traumatogenic process. It is suggested that for difficult patients the treatment of choice is dyadic psychotherapy/psychoanalysis followed by group analysis.
