The Influence of Time Estimation and Time‐Saving Preferences on Learning to Make Temporally Dependent Decisions from Experience

In this paper, we merge research related to experiential learning, temporal perception, and the value of time and money by examining decisions where the timing of action (response) determines the outcome received. We predicted that time‐saving preferences and impatience would decrease maximization (i.e., taking action when it returned the largest reward), and that the constraints of temporal perception would compound their effects. Across three studies, participants undershot on average (i.e., responded earlier than the period of time during which a response would return the maximal reward) showed a preference for shorter‐delay options and often did not find the maximal reward. In addition, participants' reliance on temporal perception increased undershooting, increased preferences for shorter‐delay options, and reduced maximization. Nevertheless, participants who found the maximal reward continued to maximize at a high rate rather than opting for shorter delays and smaller rewards. Thus, while most participants appeared to have a preference for saving time, most behaved as reward maximizers rather than temporal discounters. Copyright © 2017 John Wiley & Sons, Ltd.     

The effect of mindfulness meditation on time perception

Research has increasingly focussed on the benefits of meditation in everyday life and performance. Mindfulness in particular improves attention, working memory capacity, and reading comprehension. Given its emphasis on moment-to-moment awareness, we hypothesised that mindfulness meditation would alter time perception. Using a within-subjects design, participants carried out a temporal bisection task, where several probe durations are compared to “short” and “long” standards. Following this, participants either listened to an audiobook or a meditation that focussed on the movement of breath in the body. Finally, participants completed the temporal bisection task for a second time. The control group showed no change after the listening task. However, meditation led to a relative overestimation of durations. Within an internal clock framework, a change in attentional resources can produce longer perceived durations. This meditative effect has wider implications for the use of mindfulness as an everyday practice and a basis for clinical treatment.     

Social sharing of emotion following exposure to a negatively valenced situation

Three experimental studies are reported in which we tested the prediction that negative emotion elicits the social sharing of the emotional experience. In two experiments, participants arrived at the laboratory with a friend and then viewed one of three film excerpts (nonemotional, moderate emotion, or intense emotion) alone. Afterwards, the participants who saw the film had an opportunity to interact with the friend and their conversation was recorded. In both experiments participants who had seen the intense emotion excerpt engaged in significantly more social sharing than did participants in the other two conditions. A third experiment extended the investigation to social sharing in everyday life and replicated the previous results. Nonemotional explanations of the effects observed were also ruled out. Results are discussed in the context of the relation between emotional intensity and amount of social sharing.     

Dealing with Big Numbers: Representation and Understanding of Magnitudes Outside of Human Experience

Being able to estimate quantity is important in everyday life and for success in the STEM disciplines. However, people have difficulty reasoning about magnitudes outside of human perception (e.g., nanoseconds, geologic time). This study examines patterns of estimation errors across temporal and spatial magnitudes at large scales. We evaluated the effectiveness of hierarchical alignment in improving estimations, and transfer across dimensions. The activity was successful in increasing accuracy for temporal and spatial magnitudes, and learning transferred to the estimation of numeric magnitudes associated with events and objects. However, there were also a number of informative differences in performance on temporal, spatial, and numeric magnitude measures, suggesting that participants possess different categorical information for these scales. Educational implications are discussed.     

Knowing which day of the week it is: temporal structure and dynamics of memory

The complementary role of static and dynamic information used when one needs to be located in time was studied. Static information refers to temporal knowledge about days of the week, and dynamic information reflects a sense of time, taking into account the present, the near past, and the future. Each day of an actual 7-day wk., 699 women and 620 men were asked to provide a "right" or "wrong" response to a statement such as "Today is X," where X was the name of one of the seven days of the week. Analysis suggested use of a structured temporal representation of the week: the weekend, a landmark, had an anchoring role. Also the dynamics of the content of working memory were indicated. The active "temporal window" participants hold in mind seems directed more towards the future than the past. Results are discussed within the more general context of time management.     

Marking Time: The Effect of Timing on Appointment Keeping

The retrospective memory literature suggests that people develop internal representations of time based on the stable occurrence of events in time. Two experiments were conducted to investigate whether the temporal structure of daily life affects prospective remembering. Fifty-six subjects in Experiment 1 were randomly assigned to an appointment time scheduled either during the ‘work’ week (assumed to be more routine-filled or structured) or the weekend (assumed to be less structured). Results, while non-significant, indicated that the number of reminders may have mediated performance. There was an attempt to control this in Experiment 2. The results indicate that appointments imbedded within more structured days are more easily recalled. © 1997 John Wiley & Sons, Ltd.     

Do people really believe they are above average?

A question that has plagued self-enhancement research is whether participants truly believe the overly positive self-assessments they report, or whether better-than-average effects reflect mere hopes or self-presentation. In a test of people’s belief in the accuracy of their self-enhancing trait ratings, participants made a series of bets, each time choosing between betting that they had scored at least as high on a personality test as a random other participant, or betting on a random drawing in which the probability of success was matched to their self-assigned percentile rank on the test. They also reported the point at which they would switch their bet from their self-rating to the drawing, or vice versa. Participants were indifferent between betting on themselves or on the drawing, and it took only a slight change in the drawing’s probability for them to switch their bet, indicating that people truly believe their self-enhancing self-assessments.

时间表征是否具有空间方向性？本研究通过考察66名研究生时间表述实时加工中的空间引导效应来回答这个问题。实验一表明：空间垂直方向性图式促进被试加工含有空间词汇的时间表述;实验二表明：两种空间方向性图式,即水平方向性图式和垂直方向性图式,都促进被试加工含有纯时问词汇的时间表述。实验结果证实了时间表征具有空间方向性,并为“抽象思维以感知一动觉经验为基础”这一论点提供心理学证据。     

To switch or not to switch: Inviting bilingual clients to switch languages in psychotherapy

In the present study, we used an audio-analog design to test whether exposing bilingual participants to a therapist who invited a bilingual client to switch languages in a psychotherapy session would have a positive effect on participants’ perceptions of the therapist. We also explored whether participants’ sense of belonging to their ethnic group and to the larger US culture would enhance or attenuate this effect. Sixty-three bilingual Latino/a university students listened to one of two recordings of a simulated psychotherapy session with a bilingual Latina therapist and client. In one recording, the therapist invited the client to switch from English to Spanish when the client had trouble expressing complicated feelings; in the other, the therapist did not invite the client to switch. When listening, participants were asked to imagine themselves in the role of client and to rate the credibility and multicultural competence of the therapist, and the emotional bond they would anticipate with her. Contrary to expectation, only participants who expressed a greater sense of belonging to US culture rated the therapist who invited the client to switch as being more multiculturally competent. We discuss how these findings contribute to the literature on language switching and bilingualism in psychotherapy.     

When time stands still: fear-specific modulation of temporal bias due to threat

The current study was designed to test the fear-specific nature of temporal bias due to threat. A temporal bisection procedure was used in which participants (N = 46) were initially trained to recognize short (400 ms) and long (1,600 ms) standard durations. In the test phase, participants were asked to judge whether the duration of computer-generated faces drawn to appear threatening, fearful, and neutral, was closer to either the short or long duration they had learnt earlier. Past research was replicated-the durations of the arousing facial expressions were overestimated relative to a low arousal (neutral) expression. Overestimation for threat was positively correlated with individual differences in fearfulness, trait anxiety, and distress. Multiple regression analyses were carried out to test the hypothesis was that individual differences in anxiety and fearfulness but not other traits would uniquely predict temporal overestimation due to threat. The results showed that fearfulness but not other traits (trait anxiety, anger, distress, activity, and sociability) was a unique and strong (partial r = .47) predictor of increased overestimation for both threatening and fearful expressions. The findings support the hypothesis that threat-related expressions activate a fear-specific system (?hman & Mineka, 2001) or fear representations (Beck & Clark, 1997) in fearful individuals.     

How well is causal structure inferred from cooccurrence information?

Individual causal relations tend to form parts of larger causal systems. In five experiments the ability of participants to infer the structures of two systems involving five entities from patterns of cooccurrence was investigated. Although the systems were fully deterministic, there were no indirect causal relations, and participants were given guidance on how to infer causal structure from cooccurrence information, low rates of success were observed. Judgements were based more on information about temporal relations, even though no guidance on the use of temporal relation information for causal inference was provided. When no guidance was provided, no participants succeeded in inferring the structure of both systems. The results indicate that temporal relations may be preferred as cues to causal structure over patterns of cooccurrence.     

Time flies faster if a person has a high working-memory capacity

Attention affects the perception of time, and the ability to control attention is reflected in measures of working-memory capacity. Individuals with low working memory capacity have more difficulty maintaining focus on a task than high-capacity individuals, particularly when faced with contextual distracters. This experiment examined the effect of working-memory capacity on the perception of temporal duration while performing a cognitive task. We predicted that low-capacity participants would be more likely to direct attention away from the cognitive task and towards the contextual distraction of time, and consequently perceive temporal duration more accurately, and perform the cognitive task less accurately, than high-capacity participants. The results showed that when performing both tasks simultaneously, low-capacity participants were less accurate than high-capacity participants on the cognitive task, but were more accurate on the timing task. High-capacity participants, conversely, were more accurate in the non-temporal cognitive task at the cost of monitoring duration.     

Effects of clock monitoring on electroencephalographic activity: is unconscious movement initiation an artifact of the clock?

Electroencephalographic (EEG) activity was recorded while participants waited to make spontaneous key-press movements (Experiment 1) or waited for tones in a pitch judgment task (Experiment 2). In one condition of each experiment, participants also had to report the position of a spot traveling on a clock at the crucial time point (i.e., when they decided to move or when the tone was presented), mimicking a procedure used to assess the time of conscious awareness of an event of interest. In a second condition, there was no clock or temporal judgment. Average EEG activity preceding key presses was substantially different when participants had to monitor the clock than when they did not. Smaller clock-related differences in average EEG activity were also present preceding tone onsets. The effects of clock monitoring on EEG activity could be responsible for previous reports that movement-related brain activity begins before participants have consciously decided to move (e.g., Libet, Gleason, Wright, & Pearl, 1983).     

Intentional switching of auditory attention between long and short sequential tone patterns

The current study focuses on auditory task switching, more precisely on switching attention between different temporal patterns of the same auditory stimulus. Tone sequences consisting of nine different pitch tones were presented aurally. Three repetitive short 3-tone patterns (local focus) were combined to a long pattern (global focus), and each could be either rising or falling, resulting in congruent or incongruent combinations. Participants were informed by a cue if they had to attend to the short or to the long pattern, and they indicated if the target pattern was rising or falling by pressing one of two keys. In two experiments, we investigated cued switches between the two attentional foci. Switch costs in reaction times and errors were observed when switching from the long to the short pattern but not when switching from the short to the long pattern. These asymmetric switch costs were reduced when participants had more time to prepare for the switch in a condition with a prolonged cue-stimulus interval. In addition, participants made more errors when global and local patterns did not correspond to each other (i.e., in incongruent trials) when attending to either of the patterns, but this congruency effect was not modulated by preparation time. The data suggest that the mechanisms of task goal prioritizing, as indicated by the asymmetric attention switch costs, are dissociable from those underlying stimulus selection, as indicated by the congruency effects.     

Reward priming of temporal preparation

Recent studies have demonstrated a strong impact of reward on the expectancy of future target locations or features. In this study, we examined whether reward would have similar effects on temporal preparation. In two experiments, participants completed a reaction time task with a variable interval between a warning stimulus and the target stimulus. After each trial they were awarded either low or high reward which was converted to cash after the experiment. Crucially, reward magnitude was assigned randomly and was unrelated to task performance. Nevertheless, across experiments, the results revealed that reward modified future temporal preparation, especially in participants that could be identified as highly motivated. These findings generalize the principles of reward priming to the temporal domain.     

Temporal reproductions are influenced by an internal reference: Explaining the Vierordt effect

Several findings from duration perception literature suggest that when making decisions about time, participants rely on an internal reference memory for time rather than merely on the current physical stimuli. According to a recent account, such an internal reference is formed by a continuous dynamic updating process that integrates duration information from previous trials and the current trial. In the present work, we show how such a dynamic mechanism can account for the classical yet unresolved Vierordt effect, which refers to the overestimation of relatively short and the underestimation of relatively long temporal intervals. We conducted an experiment to examine this and related predictions by means of a temporal reproduction task. Specifically, participants were presented with two successive time intervals — a standard s with constant duration and a comparison c with variable duration. Instead of performing a comparison judgment, however, the participants were subsequently cued to reproduce one of the two presented stimuli. Reproductions were affected not only by the temporal position of the to-be-reproduced stimulus, but also by the stimuli presented on earlier trials. These results support the notion of a dynamically updated internal reference underlying our judgments about the time elapsed, which might also be the basis of the Vierordt effect.     

Representation of plans: activation in memory

The purpose of this study is to examine the temporal representation of plans in memory. Two experiments using a priming paradigm were conducted to investigate which plans would be activated in memory when participants processed a particular plan. The 64 undergraduates who participated in Experiment 1 were asked to memorise a 1-month schedule of plans. Results showed that when participants were presented with a particular plan as a prime, the preceding plan in the schedule was immediately activated. After the activation of the preceding plan, the plan following the prime plan in the schedule was activated. Experiment 2 was conducted to examine whether the sequential effect found in Experiment 1 might be based on day order (e.g., plans for day 1, plans for day 2, etc.) or simple ordering of plans (e.g., plan 1, plan 2, etc.). However, in the results of Experiment 2, with 48 undergraduate participants, the dynamic transition in the activation of plans along the time course, seen in Experiment 1, was not observed.

Validation of physical activity habit strength with subjective and objective criterion measures

ObjectivesA German version of the Self-reported Habit Strength Index (SRHI) for both sports and everyday physical activity (PA) was validated against subjective and objective criterion measures of PA.Design and methodData were obtained from 260 participants (21.4% women) in study 1 and 86 participants (58.1% women) in study 2. Both studies assessed habit strength for PA (sports and everyday PA) by the SRHI and PA by the Baecke Questionnaire (Sport, Leisure and Work Index) as subjective criterion measure, as well as by accelerometry (Step Activity Monitor or GTM1 Actigraph) as objective criterion measure. Bivariate correlations as well as path analyses were computed for the associations between the SRHI scores and subjective and objective criterion measures of PA.ResultsHighest associations for subjective criterion measure were found for habit strength for sports and the Sport Index in both studies. The Leisure Index was predicted by habit strength for sports and everyday PA. For objective criterion measures, habit strength for sports was most significantly associated with total PA in study 1 and moderate intense PA in study 2. Habit strength for everyday PA was a significant predictor of moderate intense and total PA in study 1 and low intense PA in study 2.ConclusionThe present studies replicated high internal consistencies of the SRHI for sports and everyday PA and could partially confirm their validity with subjective and objective criterion measures. The SRHI for sports seems to be more robust than the SRHI for everyday physical activity.
