We present two experiments that explore the reinforcing value of lottery tickets. Participants are faced with a repeated choice task between a safe alternative and a risky prospect that provides a chance to win a lottery ticket to be played at the end of the study. Study 1 considers situations in which the risky option leads to a slightly higher expected value than the safe alternative. It shows that the risk‐taking rate increases with the probability to win the lottery ticket, but it is below 50% even when this probability is high. Study 2 shows limited sensitivity to the expected value of the risky prospect. The results can be explained with the assumption that participants rely on small samples of past experiences, and that their reaction to lottery tickets reflects large variability. The relationship between the current results and previous research on the synergetic effect of distinct reinforcements and the “pat on the back paradox” is discussed.

Studying Deese–Roediger–McDermott (DRM) lists using a distinctive encoding task can reduce the DRM false memory illusion. Reductions for both distinctively encoded lists and non-distinctively encoded lists in a within-group design have been ascribed to use of a distinctiveness heuristic by which participants monitor their memories at test for distinctive-task details. Alternatively, participants might simply set a more conservative response criterion, which would be exceeded by distinctive list items more often than all other test items, including the critical non-studied items. To evaluate these alternatives, we compared a within-group who studied 5 lists by reading, 5 by anagram generation, and 5 by imagery, relative to a control group who studied all 15 lists by reading. Generation and imagery improved recognition accuracy by impairing relational encoding, but the within group did not show greater memory monitoring at test relative to the read control group. Critically, the within group’s pattern of list-based source judgments provided new evidence that participants successfully monitored for distinctive-task details at test. Thus, source judgments revealed evidence of qualitative, recollection-based monitoring in the within group, to which our quantitative signal-detection measure of monitoring was blind.  相似文献

Using the Deese/Roediger‐McDermott (DRM) false memory method, Smith and Hunt ( 1998 ) first reported the modality effect on false memory and showed that false recall from DRM lists was lower following visual study than following auditory study, which led to numerous studies on the mechanism of modality effect on false memory and provided many competing explanations. In the present experiment, the authors tested the modality effect in false recognition by using a blocked presentation condition and a random presentation condition. The present experiment found a modality effect different from the results of the previous research; namely, false recognition was shown to be greater following visual study than following auditory study, especially in the blocked presentation condition rather than in the random presentation condition. The authors argued that this reversed modality effect may be due to different encoding and processing characteristics between Chinese characters and English words. Compared with English words, visual graphemes of critical lures in Chinese lists are likely to be activated and encoded in participants' minds, thus it is more difficult for participants to discriminate later inner graphemes from those items presented in visual modality. Hence visual presentation could lead to more false recognition than auditory presentation in Chinese lists. The results in the present experiment demonstrated that semantic activation occurring during the encoding and retrieve phases played an important role in modality effect in false recognition, and our findings might be explained by the activation‐monitoring account.  相似文献

The current study was designed to examine the possible existence of two limited-capacity pools of central executive resources: one each for verbal and visuospatial processing. Ninety-one college students (M age = 19.0, SD = 2.2) were administered a verbal working memory task that involved updating numbers in 2-, 3-, and 4-load conditions. The task was administered in both single task (no-interference condition) and dual-task (verbal interference and visuospatial interference conditions) formats. Findings indicated main effects for both memory load and type of interference, as well as, a load × interference interaction. Verbal interference led to a steeper increase in errors on the primary verbal working memory task; whereas, there was a smaller increase in errors across load in both the non-verbal and no-interference conditions. The effect of verbal interference and the lack of a spatial interference effect on a primary task that utilized verbal working memory resources, suggests that the processing of verbal and spatial stimuli in a dual-task paradigm requires separate central executive resources.  相似文献

Scientific research in the sector of press readability and specifically magazines is not particularly extensive. This paper suggests a framework for the development of strategic decisions based on reader satisfaction measurements. The methodology is illustrated through a real-world application, i.e. customer-oriented strategy planning for the leading monthly IT magazine in Greece. This study implements the MUSA (Multicriteria Satisfaction Analysis) method to evaluate reader satisfaction, in order to support the editor in making decisions while planning his editorial strategy. Reader satisfaction was analysed based on a tree containing seven main criteria and 32 sub-criteria. Readers proved to be very satisfied and non-demanding, which results in narrower margins for efficient improvement suggestions. However, the evaluation of the MUSA results led to putting forward suggestions that could support the editor in making amendment decisions. Some of these suggestions were successfully implemented within the scope of a new strategy. This revealed the need for two separate editions, an IT magazine for pupils and students as well as an IT magazine focused on women. The decision maker received suggestions on what these new publications' features should be, deriving from the study's quantitative results. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

In 1996, Tedeschi and Quigley published a review of laboratory aggression research that included many damning criticisms of the genre. This paper revisits Tedeschi and Quigley's critique, and examines the ways that subsequent researchers have addressed the weaknesses they identified. In particular, it examines three new laboratory aggression paradigms (Hot Sauce, Bungled Procedure, and Experimental Graffiti Paradigms) that have attempted to improve upon the “classic” paradigms (Teacher/Learner & Essay Evaluation Paradigms, Competitive Reaction Time Game, Point Subtraction Aggression Paradigm, and Bobo Modelling Paradigm). In each case, this review will show, that although some aspects of the new designs are indeed improvements, many of Tedeschi and Quigley's arguments still apply. In conclusion, this investigation will identify a number of factors that future laboratory aggression researchers should consider. These include: The perceptions and motivations of the aggressor; the apparent distance between the aggressor and the target; the availability of non‐aggressive response options; the problems of demand characteristics, permissive cues and agentic shift; the differences between proactive and reactive aggression, and the distinction between overt and covert forms of aggression.

The present study proposes the future trends of Asian social psychology by taking into account its possible contribution to broad cultural and historical contexts of Asia. First, I locate social psychology in a two (nomothetic vs narrative) by two (epistemic vs design) paradigm of sciences. Second, I propose that different research perspectives in social psychology (i.e. so-called mainstream and narrative-design social psychology) may be considered as fraternal twins of the same mother, classic social psychology, and describe where each of the twins is heading. Third, I introduce two modes of research activities, Mode I and Mode II, based on previous research, and examine each twin in both modes of research. Finally, I focus on the broad context of Asia and propose that we should expand two wings, especially, the second wing over the context of the region.  相似文献

Worldwide, smartphone use is a major contributing factor to road crash among young drivers. While young drivers may be aware of their heightened crash risk and the legal penalties associated with this behaviour, young drivers continue to engage with their smartphones. The development of novel interventions targeting this behaviour is therefore crucial. The current 2 × 2 between groups experimental study (N = 153, 107F, 43 M, 1 other) investigated the concept of cognitive dissonance in relation to smartphone use among young drivers aged 17–25 years (M_age = 20.66 SD = 2.26). Specifically, it applied the induced hypocrisy paradigm to this context. The induced hypocrisy paradigm elicits cognitive dissonance by asking participants to both advocate for the desired behaviour and identify their engagement in the undesired behaviour. Participants are then motivated to change their behaviour to reduce the feelings of dissonance. The current study investigated the efficacy of both the traditional in-person methodology with a new online methodology. Analyses (e.g., ANCOVA) found that the online conditions were more effective than the in-person groups at eliciting dissonance and that the intervention conditions were more effective in reducing both intention and change in behaviour (from pre- to post-intervention) than the control groups. The intervention groups were also more likely to take/request a flyer about driver distraction. While more research is needed to corroborate these findings, these initial results suggest that cognitive dissonance occurs when young drivers use their smartphones and that the induced hypocrisy paradigm may be an effective intervention. In particular, this study’s findings suggest that an online version of the induced hypocrisy paradigm has merit and may form part of future cost-effective, mass interventions.  相似文献

Social impairments are common across many psychiatric conditions. Standardized dyadic assessments intended to elicit social affiliation between unacquainted partners are used to elucidate mechanisms that disrupt relationship formation and inform possible treatment targets; however, the psychometric properties of such paradigms remain poorly understood. This study evaluated the psychometric properties of a controlled social affiliation paradigm intended to induce connectedness between a target participant and trained confederate. Individuals with an anxiety or depressive disorder diagnosis (clinical group; n = 132) and those without (control group; n = 35) interacted face-to-face with a trained confederate; partners took turns answering a series of increasingly intimate questions about themselves. Social connectedness, affect, and affiliative behavior measures were collected during the interaction. Participant symptom and social functioning measures were collected to examine validity. The paradigm elicited escalating social connectedness throughout the task for both participants and confederates. Parallel forms (i.e., different question sets) elicited similar affiliation outcomes. Self-reported (but not behavioral) affiliation differed across some demographic variables (e.g., participant gender, Hispanic ethnicity). Within-task affiliation measures were associated with one another and with global social connectedness and social anxiety symptom measures, but not with somatic anxiety measures. Clinical participants reported lower social affiliation and positive affect reactivity and higher negative affect reactivity than healthy participants. These findings provide initial psychometric support for a standardized and controlled dyadic affiliation paradigm that could be used to reliably probe social disconnection mechanisms across psychopathology.  相似文献   

    

《Infant behavior & development》2021

The measurement of respiratory sinus arrythmia (RSA) in infants, children and adults is critical to the study of physiological regulation, and more recently, interpersonal physiological covariation, but it has been impeded by methods that limit its resolution to 30 s or longer. Recent analytical developments have suggested methods for studying dynamic RSA in adults, and we have extended this work to the study of infants and mothers. In the current paper, we describe a new analytical strategy for estimating RSA time series for infants and adults. Our new method provides a means for studying physiological synchrony in infant-mother dyads that offers some important advantages relative to existing methods that use inter-beat-intervals (e.g. Feldman, Magori-Cohen, Galili, Singer, & Louzoun, 2011). In the middle sections of this paper, we offer a brief tutorial on calculating RSA continuously with a sliding window and review the empirical evidence for determining the optimal window size. In order to confirm the reliability of our results, we briefly discuss testing synchrony by randomly shuffling the dyads to control for spurious correlations, and also by using a bootstrapping technique for calculating confidence intervals in the cross-correlation function. One important implication that emerges from applying this method is that it is possible to measure both positive and negative physiological synchrony and that these categorical measures are differentially predictive of future outcomes.  相似文献
