The authors administered a series of object displacement tasks to 24 great apes and 24 30-month-old children (Homo sapiens). Objects were placed under 1 or 2 of 3 cups by visible or invisible displacements. The series included 6 tasks: delayed response, inhibition test, A not B, rotations, transpositions, and object permanence. Apes and children solved most tasks performing at comparable levels except in the transposition task, in which apes performed better than children. Ape species performed at comparable levels in all tasks except in single transpositions, in which chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) performed better than gorillas (Gorilla gorilla) and orangutans (Pongo pygmeaus). All species found nonadjacent trials and rotations especially difficult. The number of elements that changed locations, the type of displacement, and having to inhibit predominant reaching responses were factors that negatively affected the subjects' performance. 相似文献

This study deals with the problem of whether the processing of irrelevant location information in Simon-like tasks is triggered exogenously or endogenously. In Experiment 1, the primary task required one to press, as fast as possible, a left-hand-side key or a right-hand-side key (R1) to the pitch of a tone that was presented binaurally (S1). The secondary task required identifying, without time constraints, a visual stimulus (S2) that appeared randomly to the left or right of screen center. Results showed that there was a correspondence (i.e., a cross-task Simon effect) between the location of R1 and the location of S2 when S2 was presented alone. The cross-task Simon effect became much smaller (and in-significant) when a noise stimulus was presented contralateral to S2. Experiment 2 was similar to Experiment 1, except that S2 appeared unpredictably in only one-third of the trials. Results of Experiment 2 closely replicated those of Experiment 1: the cross-task Simon effect was much greater when S2 was presented alone. Experiment 3 differed from Experiment 1 because S2 had to be processed in only one-third of the trials, in which its identity was to be reported. In the remaining two-thirds of the trials, participants could ignore S2. Results confirmed that the cross-task Simon effect was much greater when S2 was presented alone. In contrast, it did not matter whether S2 had to be processed or not. In conclusion, the present study supports the hypothesis that the task-irrelevant spatial code of the stimulus is formed automatically, likely through an exogenously triggered selection. The role of endogenously initiated selection, if any, is much less important. 相似文献

The Balanced Inventory of Desirable Responding (BIDR; Paulhus, 1994) is a widely used instrument to measure the 2 components of social desirability: self-deceptive enhancement and impression management. With respect to scoring of the BIDR, Paulhus (1994) authorized 2 methods, namely continuous scoring (all answers on the continuous answer scale are counted) and dichotomous scoring (only extreme answers are counted). In this article, we report 3 studies with student samples, and continuous and dichotomous scoring of BIDR subscales are compared with respect to reliability, convergent validity, sensitivity to instructional variations, and correlations with personality. Across studies, the scores from continuous scoring (continuous scores) showed higher Cronbach's alphas than those from dichotomous scoring (dichotomous scores). Moreover, continuous scores showed higher convergent correlations with other measures of social desirability and more consistent effects with self-presentation instructions (fake-good vs. fake-bad instructions). Finally, continuous self-deceptive enhancement scores showed higher correlations with those traits of the Five-factor model for which substantial correlations were expected (i.e., Neuroticism, Extraversion, and Conscientiousness). Consequently, these findings indicate that continuous scoring may be preferable to dichotomous scoring when assessing socially desirable responding with the BIDR. 相似文献

Effects of perceived control on nociceptive sensitivity were investigated in an experimental arrangement with N = 40 healthy volunteers in which the duration of painful pressure stimuli was made contingent on success in a tracking task. Perceived control over the pain duration was manipulated through varying the frequency of success in the tracking task. The amount of painful stimulation applied in the high and low control conditions was balanced by a yoked-control design. Pain sensitivity was measured before and after the tracking task by means of a thermal sensory analyzer. Pain sensitivity was found to decrease in the low control condition (hypoalgesia), and to increase slightly in the high control condition (hyperalgesia). These effects are explained with reference to a dual process model of coping. 相似文献

Priming of semantic classifications may occur because of response-related priming or because of priming at a more central
locus. To separate these two possibilities, we randomly intermixed adjectives and first names, using a response window procedure.
Participants decided whether the adjectives were positively or negatively valenced and whether the names were male or female.
Each of these kinds of targets was preceded by adjective or name primes associated with responses that either matched or mismatched
the correct response to the target. Results showed that priming of semantic classification involves two components: a major
response-related one, modulated by prime visibility and prime—target repetition, and a smaller component with a more central
locus that is less susceptible to context effects. 相似文献

A newly developed paradigm for studying spontaneous trait inferences (STI) was applied in 3 experiments. The authors primed dyadic stimulus behaviors involving a subject (S) and an object (O) person through degraded pictures or movies. An encoding task called for the verification of either a graphical feature or a semantic interpretation, which either fit or did not fit the primed behavior. Next, participants had to identify a trait word that appeared gradually behind a mask and that either matched or did not match the primed behavior. STI effects, defined as shorter identification latencies for matching than nonmatching traits, were stronger for S than for O traits, after graphical rather than semantic encoding decisions and after encoding failures. These findings can be explained by assuming that trait inferences are facilitated by open versus closed mindsets supposed to result from distracting (graphical) encoding tasks or encoding failures (involving nonfitting interpretations). 相似文献

Summary When two vertical rods move through a horizontal window in close succession, the Tandem Effect can be observed. It consists of a spatial illusion (distance between the rods looking smaller than it actually is) and a temporal illusion (under certain conditions both rods are seen simultaneously in the window, though the first rod has left the window before the second rod enters it). We report six experiments that explored the distance-reduction illusion and tested an attentional model of the effect. It assumes that attention is initially focused on the first rod and then shifted to the second, when it enters the window. The percept of the pair of rods is integrated from the first rod's position at the beginning, and the second rod's position at the end, of the focus shift. Consequently their subjective distance will be smaller than their physical distance by the distance that they travel during the focus shift. Experiments 1 and 2 established the Tandem Effect as an empirical phenomenon and showed that its size depends on stimulus parameters such as window size and movement speed. Experiments 3–5 tested specific predictions from the attentional model. Experiment 6 examined a further illusion, the Fröhlich Effect, and showed that it can be subsumed under the model. The experiments produced some unexpected effects and some predictions from the model were only partly confirmed. It is shown that the main findings can be combined into two quantitative functions that describe the course of focusing. One implication is that visual attention does not move from one object to another; rather all attention shifts originate in the fovea. We discuss several alternative interpretations of our data and show that they are less satisfactory than the attentional model. 相似文献

In a national study of employees across industries (N = 14,645), we examined the role of supervisor emotionally intelligent behavior for employee opportunity to grow, their affect at work, and creativity/innovation at work. Employees reported on their supervisors' emotionally intelligent behavior (perceiving, using, understanding, and managing emotions), and self‐reported about their job experiences and creativity/innovation at work. Supervisor emotionally intelligent behavior was related to employee affect at work assessed using both open‐ended questions and emotion rating scales. Furthermore, supervisor emotionally intelligent behavior was linked to employee creativity/innovation through its effect on employee opportunity to grow and higher experience of positive affect (supporting a serial mediation model). We discuss the implications of the results for creativity/innovation research and innovation management. 相似文献

Several studies have reported that parents are often reluctant to vaccinate their own or other people’s children, even when the balance of health risks and benefits clearly favors vaccination. This reluctance has been interpreted as a manifestation of “omission bias”, a general tendency to prefer inactive to active options even when inaction leads to worse outcomes or greater risks. The research raises significant public health concerns as well as worries about human decision biases in general. In this paper we argue that existing research on vaccination decisions has not convincingly demonstrated any general reluctance to vaccinate nor has it made the case that such a tendency, if found, would constitute a bias. We identify several conceptual and methodological issues that, we argue, cloud interpretation of earlier studies. In a new questionnaire-based study (Experiment 1) we examined the vaccination decisions of undergraduate students (N=103) and non-student adults (N=192). In both groups a clear majority chose to vaccinate when disease and vaccination risks were balanced. Experiments 2 and 3 identify several problems associated with the measures used in earlier studies, and show how these problems could have led to the misleading appearance of majority anti-vaccination preferences. In our data, vaccination intentions appear to be less a function of generalized preferences for action or inaction than they are of the regret respondents expect to feel if vaccination or non-vaccination were to lead to a poor outcome. Regret-avoiding choices led some respondents to favor vaccination, others to oppose it. In two follow-up studies, few respondents mentioned action or inaction per se in explaining their choices. We conclude that there is no convincing evidence that a generalized “omission bias” plays any important role in vaccination decisions. 相似文献

Der Artikel konstrastiert familiäre Lebensrealitäten und familiäre Idealvorstellungen miteinander. Für Patienten, bei denen beide weit auseinander klaffen, werden Anregungen für die Dekonstruktion selbstquälerischer Familienideale in der Psychotherapie entwickelt. Als potenziell unglücklich machend werden Familienideale beschrieben, nach denen Kinder (nur) eine Familie und Familien (nur) ein Heim brauchen; dass Familien gemeinsam verbrachte Zeit, Söhne ihre Väter und überhaupt Kinder heterosexuelle Eltern bräuchten; dass Eltern einander lieben und ihre Kinder bei sich behalten sollten; dass Kinder sich von ihren Eltern ablösen sollten. Als psychotherapeutisch nützlich werden aus Familiensoziologie und systemischer Psychotherapie die Ideen der Wahlverwandtschaft, der konsensentlasteten Diskurse und der systemischen Selbstbeobachtung empfohlen, ferner als therapeutische Techniken die zirkulären Fragen, speziell Verschlimmerungsfragen und die positive Umdeutung. Die Konstruktion neuer Rituale und die Nutzung von Netzwerkressourcen stehen am Ende der Untersuchung. 相似文献
