Introduction and objectiveAttributes are used by young, middle-aged, and older adults to describe persons in everyday life. The current study asks whether attributes are perceived similarly by different age groups: for example, some attributes could be perceived as more positive or more negative in old age than in young adulthood.MethodTo address this question, we investigated age-related differences in emotional evaluations of French adjectives. Young, middle-aged, and older adults judged 835 French adjectives on valence, arousal, and imagery.ResultsAge groups agreed highly on the relative rank order but showed mean differences for a substantial number of attributes, especially for arousal and imagery ratings. Associations between dimensions differed as well between age groups: valence and arousal were negatively correlated and this correlation was stronger in older than in younger age groups.ConclusionThe present study provided new evidence that the perception of emotionally toned material is affected by age. Several explanations to these age-related differences are discussed.  相似文献

Recent research reveals an age-related increase in positive autobiographical memory retrieval using a number of positivity measures, including valence ratings and positive word use. It is currently unclear whether the positivity shift in each of these measures co-occurs, or if age uniquely influences multiple components of autobiographical memory retrieval. The current study examined the correspondence between valence ratings and emotional word use in young and older adults' autobiographical memories. Positive word use in narratives was associated with valence ratings only in young adults' narratives. Older adults' narratives contained a consistent level of positive word use regardless of valence rating, suggesting that positive words and concepts may be chronically accessible to older adults during memory retrieval, regardless of subjective valence. Although a relation between negative word use in narratives and negative valence ratings was apparent in both young and older adults, it was stronger in older adults' narratives. These findings confirm that older adults do vary their word use in accordance with subjective valence, but they do so in a way that is different from young adults. The results also point to a potential dissociation between age-related changes in subjective valence and in positive word use.  相似文献

The self-reference effect (SRE), enhanced memory for information encoded through self-related processing, has been established in younger and older adults using single trait adjective words. We sought to examine the generality of this phenomenon by studying narrative information in these populations. Additionally, we investigated retrieval experience at recognition and whether valence of stimuli influences memory differently in young and older adults. Participants encoded trait adjectives and narratives in self-reference, semantic, or structural processing conditions, followed by tests of recall and recognition. Experiment 1 revealed an SRE for trait adjective recognition and narrative cued recall in both age groups, although the existence of an SRE for narrative recognition was unclear due to ceiling effects. Experiment 2 revealed an SRE on an adapted test of narrative recognition. Self-referential encoding was shown to enhance recollection for both trait adjectives and narrative material in Experiment 1, whereas similar estimates of recollection for self-reference and semantic conditions were found in Experiment 2. Valence effects were inconsistent but generally similar in young and older adults when they were found. Results demonstrate that the self-reference technique extends to narrative information in young and older adults and may provide a valuable intervention tool for those experiencing age-related memory decline.  相似文献

The International Affective Picture System (IAPS) has been widely used in aging-oriented research on emotion. However, no ratings for older adults are available. The aim of the present study was to close this gap by providing ratings of valence and arousal for 504 IAPS pictures by 53 young and 53 older adults. Both age groups rated positive pictures as less arousing, resulting in a stronger linear association between valence and arousal, than has been found in previous studies. This association was even stronger in older than in young adults. Older adults perceived negative pictures as more negative and more arousing and positive pictures as more positive and less arousing than young adults did. This might indicate a dedifferentiation of emotional processing in old age. On the basis of a picture recognition task, we also report memorability scores for individual pictures and how they relate to valence and arousal ratings. Data for all the pictures are archived at www.psychonomic.org/archive/.  相似文献

The main purpose of this study was to report age-based subjective age-of-acquisition (AoA) norms for 600 Turkish words. A total of 115 children, 100 young adults, 115 middle-aged adults, and 127 older adults provided AoA estimates for 600 words on a 7-point scale. The intraclass correlations suggested high reliability, and the AoA estimates were highly correlated across the four age groups. Children gave earlier AoA estimates than the three adult groups; this was true for high-frequency as well as low-frequency words. In addition to the means and standard deviations of the AoA estimates, we report word frequency, concreteness, and imageability ratings, as well as word length measures (numbers of syllables and letters), for the 600 words as supplemental materials. The present ratings represent a potentially useful database for researchers working on lexical processing as well as other aspects of cognitive processing, such as autobiographical memory.  相似文献

Processing information in relation to the self enhances subsequent item recognition in both young and older adults and further enhances recollection at least in the young. Because older adults experience recollection memory deficits, it is unknown whether self-referencing improves recollection in older adults. We examined recollection benefits from self-referential encoding in older and younger adults and further examined the quality and quantity of episodic details facilitated by self-referencing. We further investigated the influence of valence on recollection, given prior findings of age group differences in emotional memory (i.e., “positivity effects”). Across the two experiments, young and older adults processed positive and negative adjectives either for self-relevance or for semantic meaning. We found that self-referencing, relative to semantic encoding, increased recollection memory in both age groups. In Experiment 1, both groups remembered proportionally more negative than positive items when adjectives were processed semantically; however, when adjectives were processed self-referentially, both groups exhibited evidence of better recollection for the positive items, inconsistent with a positivity effect in aging. In Experiment 2, both groups reported more episodic details associated with recollected items, as measured by a memory characteristic questionnaire, for the self-reference relative to the semantic condition. Overall, these data suggest that self-referencing leads to detail-rich memory representations reflected in higher rates of recollection across age.  相似文献

Depressed and nondepressed content self-reference in mild depressives   总被引:1,自引:0,他引:1  
The present research investigated the extent to which mild depressives and normals differed in their self-referent processing of personal information. In Experiment 1, these subjects made two types of ratings on depressed (e.g., bleak, dismal) and nondepressed (e.g., loyal, organized) content personal adjectives. Half of the adjectives in each content category were rated for a semantic attribute (Does this word have a specific meaning or relate to a specific situation?), whereas half were rated for degree of self-reference (Does this word describe you?). These ratings were followed immediately by an incidental recall task, in which subjects recalled as many of the adjectives as possible. Consistent with predictions generated from a content-specific self-schema model, normals displayed superior recall for self-referenced nondepressed content adjectives, when compared to recall for self-referenced depressed content adjectives and recall for semantic ratings (both depressed and nondepressed content). In contrast, mild depressives exhibited enhanced self-referent recall for both types of content, when compared to their recall for semantic adjectives. This finding suggested that mild depressives utilize a self-schema which incorporates both depressed and nondepressed content. Experiment 2 explored this suggestion further by substituting an other-referent rating task (Does this word describe Pierre Trudeau?) for the semantic judgment used in Experiment 1. Again, consistent with a content-specific self-schema model, normals displayed superior recall only for self-referenced nondepressed adjectives. Mild depressives, however, showed enhanced self-referent recall, relative to other-referent recall, only for depressed content adjectives. For nondepressed content, mild depressives did not distinguish between the self- and other-referent conditions. This finding hinted that the nondepressed component of the mild depressives self-schema may operate at a somewhat reduced effectiveness, but only when required to differentiate between self and others.  相似文献

Two experiments were conducted to test the Spinozan model of believing. Because of their reduced cognitive resources, older adults were predicted to be more likely than young adults to believe false information. Experiment 1 used a dispositional attribution paradigm to test this hypothesis. Young and older adults were exposed to both true and false (either positive or negative) trait information about the target persons. Participants then made dispositional ratings and evaluated the target persons on overall likeability scales. Results supported the Spinozan model of believing. Older adults were more likely than young adults to believe false information and their dispositional ratings were reliably biased by the valence of false information. Experiment 2 further examined whether these false beliefs of older adults were actually conscious beliefs. It was found that older adults consciously recollected the false statements as true and these false beliefs mediated age differences in dispositional attribution.  相似文献

We introduce the Berlin Affective Word List (BAWL) in order to provide researchers with a German database containing both emotional valence and imageability ratings for more than 2,200 German words. The BAWL was cross-validated using a forced choice valence decision task in which two distinct valence categories (negative or positive) had to be assigned to a highly controlled selection of 360 words according to varying emotional content (negative, neutral, or positive). The reaction time (RT) results corroborated the valence categories: Words that had been rated as “neutral” in the norms yielded maximum RTs. The BAWL is intended to help researchers create stimulus materials for a wide range of experiments dealing with the emotional processing of words.  相似文献

Older adults sometimes show a “positivity effect” in memory, remembering proportionally more positive information than younger adults. Using a modified Memory Characteristics Questionnaire, this study examined whether emotional valence impacts the phenomenological qualities of young and older adults’ memories. Ageing did not impact the effect of valence on the qualities of high-arousal memories. However, ageing sometimes impacted subjective memory for details of low-arousal memories: In Experiment 2, older adults reported remembering more thoughts, feelings, and temporal order details about positive low-arousal stimuli, while young adults’ ratings for those dimensions were higher for negative low-arousal stimuli. These findings suggest that valence most readily affects the qualities of young and older adults’ emotional memories when those memories are low in arousal.  相似文献

We examined actual and perceived trajectories of change in life satisfaction in a national sample of 3,793 adults, ages 24 to 74 at baseline, who provided retrospective, present, and prospective ratings on two occasions 8 to 10 years apart. There was little actual change in satisfaction ratings, but there were age differences in anticipated change, with young adults expecting things to improve and older adults expecting decline. When we compared the actual (present) ratings with corresponding past or future ratings, older adults showed more temporal realism (retrospective and anticipatory ratings matched actual levels) than did young and middle-aged adults; in other words, young and middle-aged adults showed greater illusion (retrospective and prospective ratings overestimated or underestimated actual levels). At all ages, however, temporal realism was associated with more adaptive current functioning than was illusion. We discuss these findings from a life-span developmental perspective on motivational shifts from growth to maintenance and consider the implications of accuracy in evaluating the past and future.  相似文献

Affective stimuli are increasingly used in emotion research. Typically, stimuli are selected from databases providing affective norms. The validity of these norms is a critical factor with regard to the applicability of the stimuli for emotion research. We therefore probed the validity of the Leipzig Affective Norms for German (LANG) by correlating valence and arousal ratings across different sensory modalities. A sample of 120 words was selected from the LANG database, and auditory recordings of these words were obtained from two professional actors. The auditory stimuli were then rated again for valence and arousal. This cross-modal validation approach yielded very high correlations between auditory and visual ratings (>.95). These data confirm the strong validity of the Leipzig Affective Norms for German and encourage their use in emotion research.  相似文献

The aim of the present research was to determine whether lexical variables corresponding to the lexicons of young and older adults are better predictors of visual word recognition latencies than lexical variables that are not specifically adapted to the populations. Three variables were considered (subjective frequency, age of acquisition, objective frequency). Subjective frequency and age of acquisition ratings were provided by the young and older adults of the experiment, while four objective frequency measures were collected in four norms for the French language based on texts dating from different periods. As a whole, 220 words were presented to 45 young adults and 40 older adults in a lexical decision task. Regression analyses showed that objective frequency, subjective frequency, and age of acquisition were better predictors of the lexical decision latencies of young and older adults when they were accorded with the lexicons of the populations.  相似文献

While first studies suggested that emotional task material may enhance prospective memory performance in young and older adults, the extent and mechanisms of this effect are under debate. The authors explored possible differential effects of cue valence on the prospective and retrospective component of prospective memory in young and older adults. Forty-five young and 41 older adults performed a prospective memory task in which emotional valence of the prospective memory cue was manipulated (positive, negative, neutral). The multinomial model of event-based prospective memory was used to analyze effects of valence and age on the two prospective memory components separately. Results revealed an interaction indicating that age differences were smaller in both emotional valence conditions. For older adults positive cues improved the prospective component, while negative cues improved the retrospective component. No main effect of valence was found for younger adults on an overt accuracy measure, but model-based analyses showed that the retrospective component was enhanced in the positive compared with the negative cue condition. The study extends the literature in demonstrating that processes underlying emotional effects on prospective memory may differ depending on valence and age.  相似文献

Homophones are words that share phonology but differ in meaning and spelling (e.g., beach, beech). This article presents the results of normative surveys that asked young and older adults to free associate to and rate the dominance of 197 homophones. Although norms exist for young adults on word familiarity and frequency for homophones, these results supplement the literature by (1) reporting the four most frequent responses to visually presented homophones for both young and older adults, and (2) reporting young and older adults' ratings of homophone dominance. Results indicated that young and older adults gave the same first response to 67% of the homophones and rated homophone dominance similarly on 60% of the homophone sets. These results identify a subset of homophones that are preferable for research with young and older adults because of age-related equivalence in free association and dominance ratings. These norms can be downloaded from the Psychonomic Society's Web archive, www.psychonomic.org/archive/.  相似文献

Memory is susceptible to distortions. Valence and increasing age are variables known to affect memory accuracy and may increase false alarm production. Interaction between these variables and their impact on false memory was investigated in 36 young (18-28 years) and 36 older (61-83 years) healthy adults. At study, participants viewed lists of neutral words orthographically related to negative, neutral, or positive critical lures (not presented). Memory for these words was subsequently tested with a remember-know procedure. At test, items included the words seen at study and their associated critical lures, as well as sets of orthographically related neutral words not seen at study and their associated unstudied lures. Positive valence was shown to have two opposite effects on older adults' discrimination of the lures: It improved correct rejection of unstudied lures but increased false memory for critical lures (i.e., lures associated with words studied previously). Thus, increased salience triggered by positive valence may disrupt memory accuracy in older adults when discriminating among similar events. These findings likely reflect a source memory deficit due to decreased efficiency in cognitive control processes with aging.  相似文献

In young adults, valence not only alters the degree to which future events are imagined in rich episodic detail, but also how memorable these events are later on. For older adults, how valence influences episodic detail generation while imagining future events, or recalling these details at another time, remains unclear. We investigated the effect of valence on the specificity and memorability of episodic future thinking (EFT) in young and older adults. Among young and older adults, negative EFT was accompanied by less episodic detail generation relative to positive and neutral EFT. A similar reduction in episodic specificity for negative EFT was found two days later when participants recalled their previously imagined events. Notably, while older adults generated less episodically specific future thoughts relative to young adults, age did not influence the effect of valence on episodic detail generation at imagination or recollection.  相似文献
