Experiences extended across time: Evaluation of moments and episodes

Intuitions relating to outcomes extended over time are examined. Utility integration is proposed as a normative rule for the evaluation of extended episodes. In Experiment 1, subjects explicitly compared aversive experiences of varying durations. By several measures, disutility was a marginally decreasing function of episode duration, even for experiences that were thought to become increasingly aversive. This pattern is a qualitative violation of the integration rule. In Experiment 2, subjects made global evaluations of a hypothetical person's aversive experiences, on the basis of a series of subjective ratings of discomfort made at periodic intervals. The results showed an extreme sensitivity to improving or deteriorating trend and a striking neglect of duration. The final moments of an extended episode appear to exert a strong influence on the overall judgment. This leads to violations of monotonicity when adding some moments of moderate pain reduces judgments of global aversiveness.     

Predictable Mispredictions in the Context of Physical Activity and Sport: A Review

Theoretical models and research that aim to identify antecedents of participation in physical activities or sport can measure antecedents of physical activity behaviour through instruments that involve subjective predictions. In this article, we argue that such instruments may not reflect physical activity experiences or behaviour accurately because people are not very good predictors of future states. Additionally, we propose that mispredictions may be predictable because they are “caused” by tendencies to neglect processes related to hedonic adaptation and competing alternatives. We also suggest that it may be possible to improve measurement of antecedents through methods that focus respondents' attention on factors that cause mispredictions or through experiential sampling methods.     

Joint comment on "when does duration matter in judgment and decision making?" (Ariely & Loewenstein, 2000)

Recent research has demonstrated that people care about the temporal relationships within a sequence of experiences. There is considerable evidence that people pay particular attention to the way experiences improve or deteriorate over time and to their maximum (peak) and final values. D. Kahneman and coauthors suggested in earlier articles that people ignore or severely underweight duration (which they referred to as duration neglect). In the preceding article, D. Ariely and G. Loewenstein (2000) challenged the generalizability of these findings and their normative implications. In the current commentary, D. Ariely, D. Kahneman, and G. Loewenstein jointly examine the issue to provide a better understanding of what they feel they have learned from this literature and to discuss the remaining open questions.     

Recency and duration neglect in subjective assessment of television picture quality

Digitally coded television pictures exhibit transient picture impairments that can vary in intensity and duration. It is an important practical question to determine the extent to which these transient impairments affect the overall quality of a television sequence, as a function of their location within the sequence, their duration and their magnitude. Five experiments are reported. It is shown that retrospective quality ratings are poorer when the worst‐quality video occurs at the end compared to the beginning of a 30 s video sequence. This recency effect was eliminated when subjects were asked to continuously evaluate picture quality. The duration of an impairment was found to have little impact on quality ratings. A regression analysis found that quality ratings were best predicted by the peak impairment intensity. The results were interpreted in terms of Hogarth and Einhorn's ( 1992 ) belief‐adjustment model. The implications for television picture quality evaluation are discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

Curiosity about a positive or negative event prolongs the duration of emotional experience

Some researchers claim that uncertainty prolongs the duration of emotional experiences because uncertainty toward an emotion-eliciting event prolongs attention to that event. However, some results contradict this claim. We assumed that curiosity rather than uncertainty prolongs the duration of emotional experience via attention, and that attention and emotional experience are prolonged only when uncertainty elicits curiosity. This assumption is based on the information gap theory, which proposes that curiosity increases with uncertainty, but that curiosity decreases at a certain level of uncertainty. We conducted a survey study to investigate the relationships among curiosity, uncertainty, attention and duration of positive and negative emotional experiences. The results showed that curiosity, but not uncertainty, prolonged the duration of emotional experiences and the process was completely mediated by attention both for positive and negative emotions. Moreover, uncertainty prolonged the duration of emotional experiences only when uncertainty elicited curiosity, which in turn prolonged attention to the emotion-eliciting event.     

Exploring the false recognition of category exemplars: Effects of divided attention and explicit generation

Two experiments used the category repetition procedure (Dewhurst & Anderson, 1999) to test the hypothesis that false remember (R) responses occur because participants generate associates to items presented at study. Participants in Experiment 1 studied the categorised lists either with full attention or whilst performing one of two secondary tasks (articulatory suppression or random number generation). Both secondary tasks led to a reduction in the number of false R responses, with random number generation producing the greater effect. Experiment 2 manipulated the presentation duration of study items and the instructions given to participants. The numbers of false R responses were not influenced by presentation duration, but increased when participants were explicitly instructed to make associations to study items. The findings support the view that false R responses are caused by the activation of semantic associates at encoding.     

When Narrative Transportation Narrows Attention: Changes in Attentional Focus During Suspenseful Film Viewing

The construct of narrative transportation captures the psychological processes that occur when people experience an engaging narrative. Attention is an essential component of this construct: People often report feeling that they have focused attention into a narrative world, and disengaged attention from the physical environment. The goal of our research was to test if people’s attention is captured in a dynamic fashion over the course of narrative experiences. To achieve this goal, we used excerpts from narrative films. One way in which filmmakers command viewers’ attention is by generating suspense, which arises when viewers confront potential negative outcomes. In our experiments, we tested the hypothesis that hot spots, moments at which potential negative outcomes are emphasized, will narrow the viewer’s attentional focus compared to cold spots, moments that do not emphasize negative outcomes. We measured attentional tuning through latencies in reaction time to audio probes as participants viewed suspenseful film excerpts. We also administered post-viewing recognition memory tests for still images taken from hot and cold spots. Across three experiments, participants missed more probes and exhibited slower reaction times during suspenseful hot spots than cold spots. These findings provide evidence for changes in attentional tuning as people view film narratives.     

经验回顾评价中峰-终定律的检验

通过两个实验对经验回顾评价的峰终定律进行检验。实验1借鉴Fredrickson和Kahneman(1993)的实验范式,选取积极和消极视频各6个,要求40名中国大学生边看边评价,看完后给出回顾评价。实验2采用现场研究的方法,要求72名大学生,在黄金周假期中每天晚上评价当天的快乐程度,并分别在假期刚结束后,结束后三周和七周三个时间水平上回顾整个黄金周的快乐程度。结论:短时间内经验回顾评价符合峰-终定律,而长时间内经验回顾评价不符合峰-终定律。     

Duration and numerical estimation in right brain‐damaged patients with and without neglect: Lack of support for a mental time line

Previous studies have shown that left neglect patients are impaired when they have to orient their attention leftward relative to a standard in numerical comparison tasks. This finding has been accounted for by the idea that numerical magnitudes are represented along a spatial continuum oriented from left to right with small magnitudes on the left and large magnitudes on the right. Similarly, it has been proposed that duration could be represented along a mental time line that shares the properties of the number continuum. By comparing directly duration and numerosity processing, this study investigates whether or not the performance of neglect patients supports the hypothesis of a mental time line. Twenty‐two right brain‐damaged patients (11 with and 11 without left neglect), as well as 11 age‐matched healthy controls, had to judge whether a single dot presented visually lasted shorter or longer than 500 ms and whether a sequence of flashed dots was smaller or larger than 5. Digit spans were also assessed to measure verbal working memory capacities. In duration comparison, no spatial‐duration bias was found in neglect patients. Moreover, a significant correlation between verbal working memory and duration performance was observed in right brain‐damaged patients, irrespective of the presence or absence of neglect. In numerical comparison, only neglect patients showed an enhanced distance effect for numerical magnitude smaller than the standard. These results do not support the hypothesis of the existence of a mental continuum oriented from left to right for duration. We discuss an alternative account to explain the duration impairment observed in right brain‐damaged patients.     

Exploring the forgetting mechanisms in working memory: Evidence from a reasoning span test

In working memory (WM) span tests participants have to maintain to-be-remembered information while processing other, potentially distracting, information. Previous studies have shown that WM span scores are greater when span lists start with a long processing task and end with a short processing task than when these processing tasks are presented in the reverse order (e.g., Towse, Hitch, & Hutton, 2000). In Experiment 1, we obtained a similar stimulus order effect in a reasoning span test, using reasoning sentences that were equated for length in terms of the number of constituent words, but which differed in processing complexity; span scores were greater when lists began with a complex sentence and ended with a simple sentence than when this stimulus order was reversed. In Experiment 2, the stimulus order effect was not found when processing duration was held constant while sentence complexity was varied using a computer-paced moving window presentation paradigm. These results suggest that duration-based constraints can affect degree of forgetting independently of the load generated during processing phases in WM span performance and therefore imply that time-related forgetting can occur in WM span tests, particularly when the difficulty of the processing component blocks active maintenance of to-be-remembered material.     

Assimilation and contrast in organizational justice: The role of primed mindsets in the psychology of the fair process effect

This paper focuses on the psychology of the fair process effect (the frequently replicated finding that perceived procedural fairness positively affects people's reactions). It is argued that when people have received an outcome they usually assimilate their ratings of outcome fairness and affect toward their experiences of procedural fairness. As a result, ratings show fair process effects. It is also possible, however, that when people have received their outcome they compare this outcome to the procedure they experienced: Is the outcome better or worse than the procedure? A result of this comparison process may be that contrast effects are found such that higher levels of procedural fairness lead to more negative ratings of outcome fairness and affect. Research findings suggest that when comparison goals have been primed, contrast effects indeed can be found. The implications for the psychology of the fair process effect and organizational behavior are discussed.     

Visual exploration pattern in hemineglect

The analysis of eye movement parameters in visual neglect such as cumulative fixation duration, saccade amplitude, or the numbers of saccades has been used to probe attention deficits in neglect patients, since the pattern of exploratory eye movements has been taken as a strong index of attention distribution. The current overview of the literature of visual neglect has its emphasis on studies dealing with eye movement and exploration analysis. We present our own results in 15 neglect patients. The free exploration behavior was analyzed in these patients presenting 32 naturalistic color photographs of everyday scenes. Cumulative fixation duration, spatial distribution of fixations in the horizontal and vertical plane, the number and amplitude of exploratory saccades was analyzed and compared with the results of an age-matched control group. A main result of our study was that in neglect patients, fixation distribution of free exploration of natural scenes is not only influenced by the left–right bias in the horizontal direction but also by the vertical direction.     

When does duration matter in judgment and decision making?

Research on sequences of outcomes shows that people care about features of an experience, such as improvement or deterioration over time, and peak and end levels, which the discounted utility model (DU) assumes they do not care about. In contrast to the finding that some attributes are weighted more than DU predicts, Kahneman and coauthors have proposed that there is one feature of sequences that DU predicts people should care about but that people in fact ignore or underweight: duration. In this article, the authors extend this line of research by investigating the role of conversational norms (H. P. Grice, 1975), and scale-norming (D. Kahneman & T. D. Miller, 1986). The impact of these 2 factors are examined in 4 parallel studies that manipulate these factors orthogonally. The major finding is that response modes that reduce reliance on conversational norms or standard of comparison also increase the attention that participants pay to duration.     

Therapeutic moments are the key: foster children give clues to their past experience of infant trauma and neglect

Foster parents often despair over the lack of information about the past experience of the children in their care, particularly with children who have experienced infant trauma and neglect. In the context of family therapy these unknowns pose both a challenge and an opportunity. The author proposes that foster children gives clues to their past experiences in therapeutic moments, which the therapist may recognize as a result of her own inner conversation. In conjunction with a sound theoretical knowledge of infant trauma and neglect, these moments have the capacity to open a dialogue in the relationships between therapist, child and foster family. This dialogical process offers an opportunity for the child's past experience of infant trauma and neglect to be expressed in silence, and the foster parent's present experience to be heard in stillness, opening for them a way to go on beyond the family therapy sessions.     

A Randomized Trial of Two Promising Computer-Based Interventions for Students with Attention Difficulties

Few studies have examined whether attention can be improved with training, even though attention difficulties adversely affect academic achievement. The present study was a randomized-controlled trial evaluating the impact of Computerized Attention Training (CAT) and Computer Assisted Instruction (CAI) on attention and academic performance in 77 inattentive first graders. Students receiving either intervention were more likely than controls to show a moderate decline in teacher rated attention problems in first grade. Students receiving CAI also showed gains in reading fluency and in teacher ratings of academic performance. Intervention effects for attention were absent by second grade largely because attention problems declined in all groups. However, post hoc analyses indicated potential longer-term benefits for children with 6 or more inattentive symptoms at baseline. Persistent attention problems were associated with poorer academic performance in multiple domains. Results provide initial evidence that CAT and CAI can improve children’s attention in the classroom - and support additional studies to determine whether more clinically significant benefits are attainable.     

Daily experiences and well-being: Do memories of events matter?

Retrospective subjective well-being (SWB) refers to self-reported satisfaction and emotional experience over the past few weeks or months. Two studies investigated the mechanisms linking daily experiences to retrospective SWB. Participants reported events each day for 21 days (Study 1) or twice a week for two months (Study 2). The emotional intensity of each event was rated: (1) when it had recently occurred (proximal intensity); and (2) at the end of the event-reporting period (distal intensity). Both sets of ratings were then aggregated across events and used to predict retrospective SWB at the end of the study. Path analyses showed that proximal intensity predicted retrospective SWB whereas distal intensity did not. The effect remained even after controlling for trait happiness and neuroticism. These results suggest that daily experiences influence retrospective SWB primarily through abstract representations of the past few weeks or months (as measured by aggregated proximal intensity ratings) rather than the explicit recollection of individual events during the same period (as measured by aggregated distal intensity ratings). Retrospective SWB, in turn, mediated the effect of daily experiences on global SWB (i.e., self-reported satisfaction and emotional experiences in general).     

Factors affecting occupational advice for speakers who do and do not stutter

Factors affecting perceptions of occupational suitability were examined for speakers who stutter and speakers who do not stutter. In Experiment 1, 58 adults who do not stutter heard one of two audio recordings (less severe stuttering, more severe stuttering) of a speaker who stuttered. Participants rated the speaker's communicative functioning, personal attributes, and suitability for 32 occupations, along with perceptions of the occupations' speaking demands and educational requirements. Perceived speaking demand strongly affected occupational suitability ratings at both levels of stuttering severity. In Experiment 2, 58 additional adults who do not stutter heard a recording of another adult in one of two conditions (fluent speech, pseudo-stuttering), and provided the same ratings as in Experiment 1. In the pseudo-stuttering condition, participants' perceptions of occupational speaking demand again had a strong effect on occupational suitability ratings. In the fluent condition, suitability ratings were affected primarily by perceived educational demand; perceived speaking demand was of secondary importance. Across all participants in Experiment 2, occupational suitability ratings were associated with ratings of the speaker's personal attributes and communicative functioning. In both experiments, speakers who stuttered received lower suitability ratings for high speaking demand occupations than for low speaking demand occupations. Ratings for many high speaking occupations, however, fell just below the midpoint of the occupational suitability scale, suggesting that participants viewed these occupations as less appropriate, but not necessarily inappropriate, for people who stutter. Overall, the findings support the hypothesis that people who stutter may face occupational stereotyping and/or role entrapment in work settings. EDUCATIONAL OBJECTIVES: At the end of this activity the reader will be able to (a) summarize main findings on research related to the work-related experiences of people who stutter, (b) describe factors that affect perceptions of which occupations are best suited for speakers who stutter and speakers who do not stutter, and (c) discuss how findings from the present study relate to previous findings on occupational advice for people who stutter.     

Attention and the subjective expansion of time

During brief, dangerous events, such as car accidents and robberies, many people report that events seem to pass in slow motion, as if time had slowed down. We have measured a similar, although less dramatic, effect in response to unexpected, nonthreatening events. We attribute the subjective expansion of time to the engagement of attention and its influence on the amount of perceptual information processed. We term the effect time's subjective expansion (TSE) and examine here the objective temporal dynamics of these distortions. When a series of stimuli are shown in succession, the low-probability oddball stimulus in the series tends to last subjectively longer than the high-probability stimulus even when they last the same objective duration. In particular, (1) there is a latency of at least 120 msec between stimulus onset and the onset of TSE, which may be preceded by subjective temporal contraction; (2) there is a peak in TSE at which subjective time is particularly distorted at a latency of 225 msec after stimulus onset; and (3) the temporal dynamics of TSE are approximately the same in the visual and the auditory domains. Two control experiments (in which the methods of magnitude estimation and stimulus reproduction were used) replicated the temporal dynamics of TSE revealed by the method of constant stimuli, although the initial peak was not apparent with these methods. In addition, a third, control experiment (in which the method of single stimuli was used) showed that TSE in the visual domain can occur because of semantic novelty, rather than image novelty per se. Overall, the results support the view that attentional orienting underlies distortions in perceived duration.     

Ratings of Perceived Exertion by Women with Internal or External Locus of Control

Ratings of perceived exertion are frequently used to estimate the strain and effort experienced subjectively by individuals during various forms of physical activity. A number of factors, both physiological and psychological in origin, have been suggested to work as modifiers of the exertion perceived by the individual. It has been reported in non-sport-related research that individuals with an internal locus of control seem to pay more attention to relevant information and use the available information more adequately than individuals with an external locus of control. The reputed inferior information-processing abilities of externals compared with internals could possibly also influence the ratings of perceived exertion, with externals being less accurate in their ratings. Whether locus of control might be such a factor was investigated. Fifty women worked on an ergometer cycle at four different work loads. The results showed statistically significant differences in subjective ratings of perceived exertion between externals and internals, especially at heavier work loads. Such differences might be because of unequal information-processing abilities, as the observed discrepancies occurred at higher work intensities, when more cues are available for processing.
