Path dependent preferences: The role of early experience and biased search in preference development 总被引:2,自引:0,他引:2
Steve Hoeffler Dan Ariely Pat West 《Organizational behavior and human decision processes》2006,101(2):215-229
What is the role of early experiences in shaping preferences? What are the mechanisms by which such early encounters influence the way preferences are formed? In this research, we examine the impact of the entry position and favorability of initial (and ongoing) experiences on preference development. We predict that the starting point will heavily influence which particular region people select from initially, and favorableness of early experiences and myopic search will both limit their search to that particular region. Across four studies, we find that when the initial experiences are favorable, subjects engage in lower levels of search, experience only a narrow breadth of possible alternatives, demonstrate less ongoing experimentation, and have a reduction in the amount of preference development. 相似文献

An in vivo tendon force measurement system was used to evaluate index finger flexor motor control patterns during active finger flexion. During open carpal tunnel release surgery (N=12) the flexor digitorum profundus (FDP) and flexor digitorum superficilias (FDS) tendons were instrumented with buckle force transducers and participants performed finger flexion at two different wrist angles (0 degrees or 30 degrees ). During finger flexion, there was concurrent change of metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint angles, but the FDP and FDS tendon force changes were not concurrent. For the FDS tendon, no consistent changes in force were observed across participants at either wrist angle. For the FDP tendon, there were two force patterns. With the wrist in a neutral posture, the movement was initiated without force from the finger flexors, and further flexion (after the first 0.5s) was carried out with force from the FDP. With the wrist in a flexed posture, the motion was generally both initiated and continued using FDP force. At some wrist postures, finger flexion was initiated by passive forces which were replaced by FDP force to complete the motion. 相似文献

We tested a mediation model of social connectedness and guilt and shame. Social connectedness was hypothesized to be related to greater hope and differentiation of self. Hope and differentiation of self, in turn, were expected to be related to less shame and more prosocial guilt. The results found that hope mediated the relationship between social connectedness and guilt, and differentiation of self mediated the relationship between social connectedness and shame. Alternative explanatory models were explored and taken into consideration in the interpretation of the results. 相似文献

We examined the spatial and temporal limitations of the visual corrective process in goal-directed aiming, as well as gender differences in online control. An initial experiment was conducted to test the utility of a monocular switch procedure as a method of rapidly introducing a visual perturbation. The results revealed minimal effect of the monocular switch on movement time and the endpoint error. Following this control experiment, prismatic displacement was introduced at the initiation of and during the movement. In the third experiment, the prism was presented prior to movement initiation, and then removed at the beginning of or during the movement. Movement trajectories were most influenced by the early presentation and removal of the prism, and female performance was significantly more affected by both perturbations than male performance. 相似文献

Temporal distribution of favourite books, movies, and records: differential encoding and re-sampling 总被引:1,自引:0,他引:1
The reminiscence bump is the effect that people recall more personal events from early adulthood than from childhood or adulthood. The bump has been examined extensively. However, the question of whether the bump is caused by differential encoding or re-sampling is still unanswered. To examine this issue, participants were asked to name their three favourite books, movies, and records. Furthermore,they were asked when they first encountered them. We compared the temporal distributions and found that they all showed recency effects and reminiscence bumps. The distribution of favourite books had the largest recency effect and the distribution of favourite records had the largest reminiscence bump. We can explain these results by the difference in rehearsal. Books are read two or three times, movies are watched more frequently, whereas records are listened to numerous times. The results suggest that differential encoding initially causes the reminiscence bump and that re-sampling increases the bump further. 相似文献

The results of a functional analysis of problem behavior and a paired-choice assessment were compared to determine whether the same social reinforcers were identified for problem behavior and an appropriate response (time allocation). The two assessments were conducted in classroom settings with 4 adolescents with mental retardation who engaged in severe problem behavior. Each student's classroom teacher served as the therapist for all phases of assessment. The two assessment procedures identified the same social reinforcers for problem and appropriate behavior for 3 of 4 participants. 相似文献

The mixed-list paradox is the finding that high-frequency words show a recall advantage in blocked lists, but that this advantage
is reversed or nullified in mixed lists. We argue that this paradox has been poorly defined. Specifically, researchers should
investigate random and alternating lists separately. We examine blocked, random, and alternating lists in our experiment.
We hypothesize that a low-frequency recall advantage could arise due to asymmetrically strong links between low- and high-frequency
words. Supporting our hypothesis, a lowfrequency recall advantage is observed in the random list, as is an asymmetry of association.
In the alternating list, no recall advantage is observed, and neither is any asymmetry of association. Our results offer a
clear challenge to future research to (1) consider the associations between word frequencies and (2) consider random and alternating
lists separately. 相似文献

Eye-blink conditioning involves the pairing of a conditioned stimulus (usually a tone) to an unconditioned stimulus (air puff), and it is well established that an intact cerebellum and interpositus nucleus, in particular, are required for this form of classical conditioning. Changes in synaptic number or structure have long been proposed as a mechanism that may underlie learning and memory, but localizing these changes has been difficult. Thus, the current experiment took advantage of the large amount of research conducted on the neural circuitry that supports eye-blink conditioning by examining synaptic changes in the rabbit interpositus nucleus. Synaptic quantifications included total number of synapses per neuron, numbers of excitatory versus inhibitory synapses, synaptic curvature, synaptic perforations, and the maximum length of the synapses. No overall changes in synaptic number, shape, or perforations were observed. There was, however, a significant increase in the length of excitatory synapses in the conditioned animals. This increase in synaptic length was particularly evident in the concave-shaped synapses. These results, together with previous findings, begin to describe a sequence of synaptic change in the interpositus nuclei following eye-blink conditioning that would appear to begin with structural change and end with an increase in synaptic number. 相似文献

In Britain at least, secularisation has proceeded to the point where the characteristics that conventionally divide churches, denominations, sects, and cults as types of religious organisation have largely disappeared. Drawing on survey data and newspaper reports collected over the last three decades, we argue that societal hostility now focuses so narrowly on tangential aspects of religion that the characteristic of existing in a high degree of tension with the wider environment (which is central to most definitions of the sect) is increasingly rare and is now likely to be applied to churches and denominations. The article concludes with a suggestion for a new typology. 相似文献

Although individual- and team-level studies of motivational processes abound, very few have sought to link such phenomena across levels. Filling this gap, we build upon Chen and Kanfer’s (2006) multilevel theoretical model of motivation in teams, to advance and test a cross-level model of relationships between individual and team motivation and performance. Data from two samples of undergraduates performing simulated team tasks supported the direct and mediated cross-level relationships between team-level prior performance, efficacy, and action processes with individual-level self-efficacy, goal striving, and performance. The findings provide support for a multilevel, system-based formulation of motivation and performance in teams. Findings also contribute to the on-going debate on whether motivational processes account for performance once controlling for prior performance. 相似文献
