信任者权力对其人际信任的影响

信任者权力对其人际信任的影响是基于双方权力的不对等实现的还是取决于信任者自身的权力水平的问题值得研究。为此,本研究在实验一中考查了信任博弈任务中信任者的权力感（与被信任者的权力水平无关）对其人际信任的影响,在实验二中通过角色扮演任务操纵信任者与被信任者的权力关系（对等vs.不对等）,同时测量信任者的人际信任倾向。结果表明：信任者自身的权力感影响其人际信任,低权力感个体比高权力感个体更信任他人;双方权力对等与否对信任者的人际信任倾向没有影响。可见,信任者权力更多是作为信任者自身的属性特征影响其人际信任,而不以双方权力层级不对等为前提。     

Guessing Strategies, Aging, and Bias Effects in Perceptual Identification

In the typical single-stimulus perceptual identification task, accuracy is improved by prior study of test words, a repetition priming benefit. There is also a cost, inasmuch as previously studied words are likely to be produced (incorrectly) as responses if the test word is orthographically similar but not identical to a studied word. In two-alternative forced-choice perceptual identification, a test word is flashed and followed by two alternatives, one of which is the correct response. When the two alternatives are orthographically similar, test words identical to previously studied items are identified more accurately than new words (a benefit) but tests words orthographically similar to studied words are identified less accurately than new words (a cost). Ratcliff and McKoon (in press) argue that these are bias effects that arise in the decision stage of word identification. We report five experiments that examined the alternative hypothesis that these bias effects arise from postperceptual guessing strategies. In single-stimulus perceptual identification, repetition priming benefits were equally great for young and older adults who claimed to use deliberate guessing strategies and those who did not (Experiment 1). In contrast, only groups of young and older people who claimed to deliberately guess studied words in a two-alternative forced-choice task (Experiments 2 and 5) showed reliable benefits and costs. Costs and benefits were abolished in the two-alternative forced-choice task when a very long study list was used, presumably because the increased retrieval burden made the use of deliberate guessing strategies less attractive (Experiment 3). Under conditions similar to those of Experiment 3, repetition priming was observed in single-stimulus perceptual identification (Experiment 4). These results are consistent with the view that costs and benefits in the forced-choice perceptual identification task arise from deliberate guessing strategies but that those in the single-stimulus task do not. The possibility that the observed relationship between strategy reports and priming effects reflects erroneous postexperimental assessments of strategies by participants is also considered.     

The costs of changing the representation of action: response repetition and response-response compatibility in dual tasks

In 5 experiments, the authors investigated the costs associated with repeating the same or a similar response in a dual-task setting. Using a psychological refractory period paradigm, they obtained response-repetition costs when the cognitive representation of a specific response (i.e., the category-response mapping) changed (Experiment 1) but benefits when it did not change (Experiment 2). The analogous pattern of results was found for conceptually similar (i.e. compatible) responses. Response-response compatibility costs occurred when the cognitive representations of the compatible responses were different (Experiments 3A & 3B), but compatibility benefits occurred when they were the same (Experiment 4). The authors interpret the costs of repeating an identical or compatible response in terms of a general mechanism of action selection that involves coding the task-specific meaning of a response.     

Resisting revenge: An investigation of reasons for foregoing revenge in romantic relationships

The reasons people offered to explain why they resisted the desire to retaliate when provoked by a romantic partner were investigated in two studies. Undergraduates recalled an instance when they wanted to get even with a romantic partner but chose not to and either explained their reasons for foregoing revenge (Study 1, N = 27) or selected reasons from a checklist (Study 2, N = 91). Results suggest people succumb to the temptation to take revenge when they (a) do not stop to question the morality of responding vengefully, (b) do not consider the costs of retaliating (or perceive its benefits to outweigh its costs), or (c) weigh the harm that vengeance might cause their avengee/relationship less heavily than its benefits.     

3～4岁儿童基于可信度特质的信任判断:特质间差异和年龄特点

研究采用对偶选择的范式,通过两个实验考察了96名3～4岁儿童基于可信度特质的信任判断。研究同时测量儿童基于可信度特质(能干、友好和诚实)的信任判断能力和针对这些特质的好坏评价能力。结果发现:(1)信任判断的正确率在3种可信度特质间不存在差异。(2)在信任判断之后再进行好坏评价的情况下(实验一),4岁儿童信任判断的正确率高于3岁,在控制好坏评价能力之后,年龄差异依然存在。(3)在信任判断之前先进行好坏评价的情况下(实验二),则信任判断的正确率不存在年龄差异。这些结果表明不是因为好坏评价能力的缺陷,而可能是任务本身较重的认知负荷使得3岁儿童不能像4岁儿童那样自发地依据特质的效价信息进行信任判断。     

Task-set reconfiguration with binary and three-valued task dimensions

 Recently, we [Kleinsorge & Heuer (1999) Psychological Research, 62, 300–312] introduced the notion of generalizing switching operations to account for a characteristic pattern of shift costs that can be observed when participants have to shift between four tasks that result from an orthogonal combination of the two binary task dimensions kind of judgment (numerical vs spatial) and judgment-to-response mapping (compatible vs incompatible). Specifically, while a change of the kind of judgment always results in costs, a change of mapping results in costs only when the kind of judgment is repeated, but results in benefits when the kind of judgment changes as well. In Experiment 1, we replicated and extended this finding with a combination of two spatial kinds of judgment that were more similar to each other and were more unlikely to result in build-in dependencies of the two task dimensions. In Experiment 2, we extended this design to a combination of nine tasks that resulted from a factorial combination of two three-valued task dimensions. In this experiment, shift costs grew monotonically with the number of task dimensions on which a change took place. This outcome is consistent with the assumption that a generalizing switching operation is a forward-acting process that requires a specific target value to switch to.

Wiping out memories: New support for a mental context change account of directed forgetting

Costs and benefits of directed forgetting are observed when a between-list instruction to forget List 1 impairs List 1 recall while enhancing List 2 recall. These effects are often ascribed to intentional inhibition of List 1. Contrary to this inhibition account, we found that a forget instruction did not produce costs unless an explicit instruction to concentrate on List 2 was used (Experiment 1). Alternatively, costs may be ascribed to a shift in mental context between encoding and retrieval. Consistent with this mental context-change account, an unexpected task (wiping the computer screen and one's hands) produced costs comparable to a forget instruction, as did as a brief chat between lists (Experiment 2). A number-search task between lists produced neither costs nor benefits (Experiment 3), suggesting that mere distraction is insufficient for inducing mental context change. Our findings support the claim that mental context change underlies both intentional and unintentional forgetting.     

A double-edged sword: How social diversity affects trust in representatives via perceived competence and warmth

Previous research has claimed that diversity erodes trust, even though the empirical evidence is mixed and restricted to ethnic neighborhood diversity. Against the backdrop of increasing diversity within the political sphere and concurrently declining political trust, we examined the impact of social diversity on trust in groups of political representatives. In two experiments (N₁ = 109, N₂ = 248) we tested how the diversity of political parties affected citizens’ trust in them. In line with predictions of the stereotype content model, diverse parties were perceived as warmer and less competent than non-diverse parties (Experiments 1–2). Additionally, party diversity was perceived as having more benefits, but also involving more threats (Experiment 2). Consequently, diversity had both positive (via warmth and benefits) and negative (via competence and threats) indirect effects on trust. These results help to untangle previously mixed, for the most part non-experimental, findings of the relationship between diversity and trust.     

Does cost–benefit analysis or self‐control predict involvement in two forms of aggression?

The main aim of this research was to assess the relative association between physical aggression and (1) self‐control and (2) cost‐benefit assessment, these variables representing the operation of impulsive and reflective processes. Study 1 involved direct and indirect aggression among young Indian men, and Study 2 physical aggression to dating partners among Spanish adolescents. In Study 1, perceived benefits and costs but not self‐control were associated with direct aggression at other men, and the association remained when their close association with indirect aggression was controlled. In Study 2, benefits and self‐control showed significant and independent associations (positive for benefits, negative for self‐control) with physical aggression at other‐sex partners. Although being victimized was also correlated in the same direction with self‐control and benefits, perpetration and being victimized were highly correlated, and there was no association between being victimized and these variables when perpetration was controlled. These results support the theory that reflective (cost‐benefit analyses) processes and impulsive (self‐control) processes operate in parallel in affecting aggression. The finding that male adolescents perceived more costs and fewer benefits from physical aggression to a partner than female adolescents did is consistent with findings indicating greater social disapproval of men hitting women than vice versa, rather than with the view that male violence to women is facilitated by internalized patriarchal values.

Repetition in visual word identification: Benefits and costs

University students performed lexical tasks with visually presented target words after the presentation of an identical or unrelated prime, at short (80–120?ms) or longer (410–710?ms) prime–target stimulus onset asynchronies (SOAs). Experiment 1 showed perceptual identification benefits in vocal responding at a short SOA that were reduced (accuracy) or reversed (latency) at a longer SOA. Experiment 2 showed a transition from a repetition benefit to a cost over 3 SOAs in a target-masked version of the lexical decision task (LDT; target displayed for only 141?ms). In Experiment 3 the repetition cost was replicated at a 530-ms SOA in the LDT with masked targets, but a repetition benefit was observed in the conventional LDT (target displayed until response). The dependence of repetition costs on target masking is more consistent with biases based on episodic confusions than refractoriness of lexical representations.     

Trust in the workplace: factors affecting trust formation between team members

The authors used survey data from 127 professional-level employees working in 8 industries to assess the effects of respondent's trusting stance and (a) the trustee's organization membership (internal or external), (b) the hierarchical relationship (supervisor or peer), and (c) the gender of the trustee, on initial trust level for a new project team member. The authors found that trusting stance was positively related to initial trust level. The authors also found an interaction effect between respondent gender and trustee gender on initial trust. Specifically, male initial trust level was higher for a new male team member and lower for a new female team member. The present study provided additional understanding of the formation of initial trust levels and its importance for team functioning.     

An examination of the continuous distractor task and the “long-term recency effect”

The continuous distractor task has yielded a so-called "long-term recency effect" that appears to call into question the dual-storage explanation of serial position effects in free recall. In this study, we show that the "long-term recency effect" is really a short-term storage effect, resulting from adaptation to the repeated presentation of a particular type of distractor throughout the list. This adaptation, a time-sharing process, permits short-term storage to carry out its normal functions. Experiment 1 shows that an appropriate postlist distractor task does in fact eliminate the "long-term recency effect." This finding supports the assertion that the effect is a product of short-term storage. Experiment 2 demonstrates the benefits and costs of the time-sharing process, relative to standard free recall, for both long-term and short-term storage. The findings support the time-sharing hypothesis. Experiment 3 replicates Experiment 2, with a change in procedure that rules out output interference as a mechanism responsible for the results of Experiment 2. Data are also presented on the development of the adaptation over trials. It is concluded that the adaptation and time-sharing processes need to be included in the dual-storage model of short-term storage.     

Response-repetition effects in task switching with and without response execution

Previous research into the mechanisms of task switching has shown that repeating the same response in a different task context is associated with costs. To investigate whether such response-repetition costs occur even when the first of the two responses is not overtly executed, we used a variant of the change-signal paradigm. Subjects responded to a first stimulus by pressing a left or right response key. In half of the trials, a second stimulus occurred after a variable, adaptively adjusted delay, indicating to abandon the first response, and only respond to the second stimulus using another set of left and right response keys. In Experiment 1, different tasks had to be performed with the first and second stimulus (task-switch condition); in Experiment 2, the same task had to be performed with both stimuli (task-repetition condition). Response-repetition costs were obtained in Experiment 1, and response-repetition benefits in Experiment 2. Importantly, these costs and benefits were obtained even when the first of the two responses had not been overtly executed. The data support the idea that interference of task-specific response codes occurs at the level of abstract response codes. Interference of such response codes occurs even when the responses are not overtly executed.     

Trust, Mood, and Outcomes of Friendship Determine Preferences for Real Versus Ersatz Social Capital

Societal-level social capital ultimately rests upon individual attitudes and behaviors. This study investigated the determinants of individuals' preferences for real versus ersatz social activities. Ersatz social activities are substitutes for true social interaction; they involve interaction with media or media characters rather than other individuals. Undergraduates ( N = 144 ) chose activities from pairs of social and ersatz exemplars. The participants were randomly assigned to one of four conditions. In two of these conditions, they wrote essays designed to create either a positive or negative mood; in the other two conditions, they read essays designed to highlight either the costs or benefits of friendship. Results indicated that individuals low in trust were susceptible to situational influences. Low-trust individuals chose more real social activities when in a positive mood or when benefits of friendship were salient, whereas they chose ersatz social activities when in a bad mood or when costs of friendship were salient. High-trust individuals showed relatively high preference for real social interactions regardless of mood or the salience of costs and benefits. These results suggest that appropriate interventions should overcome low trust to build social capital.     

Is it impossible to inhibit isoluminant items, or does it simply take longer? Evidence from preview search

Visual search can be facilitated when participants receive a preview of half the distractors (the preview benefit in search; Watson & Humphreys, 1997). Donk and Theeuwes (2001) have argued that preview-based benefits are abolished if the display items are isoluminant to a background. This is consistent with the preview benefit being due to onset capture by the new stimuli. In contrast, the present experiments challenge this suggestion and show that preview benefits can occur under isoluminant conditions, providing that they are given enough time to occur. In Experiment 1, we showed that a preview benefit can occur even with isoluminant stimuli, provided that the old items are previewed for a sufficient time. In Experiment 2, we tested and rejected the idea that this advantage is due to low-level sensory fatigue for the preview stimuli. These findings indicate that the preview effect is not caused solely by onset capture.     

Response-based strengthening in task shifting: evidence from shift effects produced by errors

The hypothesis is introduced that 1 source of shift costs is the strengthening of task-related associations occurring whenever an overt response is produced. The authors tested this account by examining shift effects following errors and error compensation processes. The authors predicted that following a specific type of error, called task confusion, shift benefits instead of shift costs should result. A series of 3 experiments confirmed this prediction showing that task confusions produce shift benefits in subsequent trials (Experiment 1), even when the error is detected (Experiment 2). Moreover, only posterror processes that imply an error correction response produce shift costs (Experiment 3). These results additionally suggest that error detection cannot prevent errors from affecting subsequent performance.     

The dynamics of trust: comparing humans to automation

Complex industrial environments involve cooperation between operators and automation. The strategies used to allocate tasks to automation are a crucial component of that cooperation and are known to be affected by the operators' trust in the automation. In 2 simulated process control experiments, the authors compared trust in automation with trust in human partners in equivalent situations. Experiment 1 found the relationship between trust and task allocation to be qualitatively identical, but quantitatively attenuated, for human partners as compared with automation. Experiment 2 additionally identified the operators' trustworthiness, as they thought it would be perceived by a human partner, as crucial to task allocation under human collaboration but not under automation. The results imply that human collaboration benefits from calibration of people's assessment of how others perceive them.     

Exploring temporal dissipation of attention settings in auditory task switching

Using a cued auditory task-switching variant of dichotic listening, we varied the response–cue interval (RCI) to examine temporal dissipation effects. On each trial, participants were presented with two different number words, one spoken by a female speaker and another by a male speaker (dichotic listening), that served as competing targets for a numerical judgment. The gender of the task-relevant speaker was indicated by a visual task cue prior to each trial. Experiment 1A used two different cues for each task (i.e., gender) and showed only small cue repetition benefits (same cue vs. alternate cue) but large auditory switch costs (alternate cue vs. task switch). A replication without immediate cue repetitions (Experiment 1B) showed very similar switch costs, suggesting that immediate cue repetitions play a negligible role for the size of auditory task switch costs. Moreover, switch costs were reduced when the (entirely task-irrelevant) location of the task-relevant speaker changed, relative to when it was unchanged, suggesting an episodic feature-binding component in our dichotic-listening task. Importantly, both experiments showed no effect of RCI on auditory switch costs. Because statistical power for this null effect was reasonably high across experiments (n?=?50), this finding suggests that auditory attention settings do not dissipate quickly over time.     

When does testing enhance retention? A distribution-based interpretation of retrieval as a memory modifier

Tests, as learning events, can enhance subsequent recall more than do additional study opportunities, even without feedback. Such advantages of testing tend to appear, however, only at long retention intervals and/or when criterion tests stress recall, rather than recognition, processes. We propose that the interaction of the benefits of testing versus restudying with final-test delay and format reflects not only that successful retrievals are more powerful learning events than are re-presentations but also that the distribution of memory strengths across items is shifted differentially by testing and restudying. The benefits of initial testing over restudying, in this view, should increase as the delay or format of the final test makes that test more difficult. Final-test difficulty, not the similarity of initial-test and final-test conditions, should determine the benefits of testing. In Experiments 1 and 2 we indeed found that initial cued-recall testing enhanced subsequent recall more than did restudying when the final test was a difficult (free-recall) test but not when it was an easier (cued-recall) test that matched the initial test. The results of Experiment 3 supported a new prediction of the distribution framework: namely, that the final cued-recall test that did not show a benefit of testing in Experiment 1 should show such a benefit when that test was made more difficult by introducing retroactive interference. Overall, our results suggest that the differential consequences of initial testing versus restudying reflect, in part, differences in how items distributions are shifted by testing and studying.     

Abrupt onsets capture attention independent of top-down control settings II: Additivity is no evidence for filtering

Is attentional capture contingent on top-down control settings or involuntarily driven by salient stimuli? Supporting the stimulus-driven attentional capture view, Schreij, Owens, and Theeuwes (2008) found that an onset distractor caused a response delay, in spite of participants’ having adopted an attentional set for a color feature. However, Folk, Remington, and Wu (2009) claimed that this delay reflects separate, nonspatial filtering costs instead, because the onset effects were additive with color-based capture effects, and capture should have caused underadditivity. The present Experiment 1 shows that contingent capture caused by additional color cues is also additive, just like the onset effect. This makes additivity a dubious diagnostic with regard to spatial capture. Experiment 2 demonstrates that it is possible to obtain underadditivity when attention-demanding distractors have sufficient capturing power. Experiment 3 shows that the abrupt onset interference turns into a benefit when the locations of the onset and the target coincide. Together, these results argue in favor of stimulus-driven attentional capture by abrupt onsets.
