Do approach-avoidance actions create attitudes? Prior influential studies suggested that rudimentary attitudes could be established by simply pairing novel stimuli (Chinese ideographs) with arm flexion (approach) or arm extension (avoidance). In three experiments, we found that approach-avoidance actions alone were insufficient to account for such effects. Instead, we found that these affective influences resulted from the interaction of these actions with a priori differences in stimulus valence. Thus, with negative stimuli, the effect of extension on attitude was more positive than the effect of flexion. Experiment 2 demonstrated that the affect from motivationally compatible or incompatible action can also influence task evaluations. A final experiment, using Chinese ideographs from the original studies, confirmed these findings. Both approach and avoidance actions led to more positive evaluations of the ideographs when the actions were motivationally compatible with the prior valence of the ideographs. The attitudinal impact of approach-avoidance action thus reflects its situated meaning, which depends on the valence of stimuli being approached or avoided. 相似文献

The visual system relies on several heuristics to direct attention to important locations and objects. One of these mechanisms directs attention to sudden changes in the environment. Although a substantial body of research suggests that this capture of attention occurs only for the abrupt appearance of a new perceptual object, more recent evidence shows that some luminance-based transients (e.g., motion and looming) and some types of brightness change also capture attention. These findings show that new objects are not necessary for attention capture. The present study tested whether they are even sufficient. That is, does a new object attract attention because the visual system is sensitive to new objects or because it is sensitive to the transients that new objects create? In two experiments using a visual search task, new objects did not capture attention unless they created a strong local luminance transient. 相似文献

A common misconception exists that criminal offenders specialize in types of crime, such as serial murders, domestic violence, and sex offenses. This article explores the research on specialization in general criminal offenders, domestic violence offenders, and sex offenders. This review finds that although there are a few specialists, the majority of criminal offenders are generalists who exhibit wide versatility in offending. The implications for legal and mental health policies are discussed. 相似文献

Results from previous visual search studies have suggested that abrupt onsets produce involuntary shifts of attention (i.e., attentional capture), but discontinuities in simple features such as color and brightness do not (Jonides & Yantis, 1988). In the present study we tested whether feature discontinuities (i.e., “singletons”) can produce attentional capture in a visual search task if defined “locally” or over a small spatial range. On each trial, a variable number of letters appeared, one of which differed from the others in color or intensity. The location of this singleton was uncorrelated with target location. Local discontinuities were created by embedding the letters in a dot texture. In Experiment 1, display size effects for singleton targets were not reduced with the addition of a background dot texture. Similar results were obtained in Experiment 2, regardless of variations in texture density. Experiment 3 confirmed that when targets are defined by a color or intensity singleton, they are detected preattentively, and that increasing texture density yields faster detection. We conclude that the spatial range over which feature discontinuities are defined may influence the guidance of spatial attention, but it has no influence on their ability to capture attention. 相似文献

Under certain circumstances, external stimuli will elicit an involuntary shift of spatial attention, referred to as attentional capture. According to the contingent involuntary orienting account (Folk, Remington, & Johnston, 1992), capture is conditioned by top-down factors that set attention to respond involuntarily to stimulus properties relevant to one's behavioral goals. Evidence for this comes from spatial cuing studies showing that a spatial cuing effect is observed only when cues have goal-relevant properties. Here, we examine alternative, decision-level explanations of the spatial cuing effect that attribute evidence of capture to postpresentation delays in the voluntary allocation of attention, rather than to on-line involuntary shifts in direct response to the cue. In three spatial cuing experiments, delayed-allocation accounts were tested by examining whether items at the cued location were preferentially processed. The experiments provide evidence that costs and benefits in spatial cuing experiments do reflect the on-line capture of attention. The implications of these results for models of attentional control are discussed. 相似文献

In recent years, the topic of car-following has become of increased importance in traffic engineering and safety research. Models of this phenomenon, which describe the interaction between (typically) adjacent vehicles in the same lane, now form the cornerstone for many important areas of research including (a) simulation modelling, where the car-following model (amongst others) controls the motion of the vehicles in the network, and (b) the functional definition of advanced vehicle control and safety systems (AVCSS), which are being introduced as a driver safety aid in an effort to mimic driver behaviour but remove human error. Despite the importance of this area however, no overview of the models availability and validity exists. It is the intent of this paper therefore to briefly assess the range of options available in the choice of car-following model, and assess just how far work has proceeded in our understanding of what, at times, would appear to be a simple process. 相似文献

The field of metaethics, the branch of moral philosophy that examines the nature and status of morality, is rich in theoretical diversity. Nonetheless, a majority of professional philosophers embrace a subset of theories that affirm the existence of objective moral facts. I suggest that this may be related to the very method that philosophers use to construct metaethical theories. This method involves analyzing how ordinary people think and argue about morality. Analysis of ordinary moral discourse is meant to reveal common platitudes (or truisms) about the nature of morality itself, including the platitude that morality trades in objective moral facts. But do philosophers investigate ordinary moral discourse in any systematic way? How do they arrive at such platitudes? On what grounds are they justified? In this paper, I critically examine these questions and argue that a) any such platitudes need to be investigated systematically through empirical research and b) philosophers ought to be engaged in this research themselves. 相似文献

Over 90% of the United States population affiliates with an organised religion. There has been, however, very little research regarding religion in work organisations. This study focuses on the effects of individual perceptions of religious dissimilarity, as a characteristic of deep-level diversity, on perceived cohesion. A scale is developed to measure individual perceptions of the dissimilarity of religion. Two different studies are used to establish reliability and validity of this scale. In addition, some implications of the negative relationship between individual perceptions of religious dissimilarity and perceived cohesion for organisations are discussed. 相似文献

Two prospective studies have investigated whether the presence, intrusion, and avoidance of negative intrusive memories predict depression, and have reported conflicting findings. We aimed to replicate and extend these investigations by exploring the role of intrusion and avoidance of intrusive memories, as well as memory characteristics, in the prediction of depression prospectively. At Time 1 a mixed sample of community participants (N=85) were interviewed and completed self-report measures of depression, anxiety, and intrusive memory features. At Time 2 (6 months later, N=64) depression and anxiety symptoms were reassessed. Results were partly consistent with hypotheses for the sub-sample of participants who did not receive treatment between the baseline and follow-up assessments. Baseline levels of intrusion and some memory features (uncontrollability, distress, interference, numbness, detachment) predicted follow-up depression, controlling for baseline depression symptoms. Unexpectedly, avoidance of intrusive memories and other features (e.g., here and now quality) did not predict depression. Levels of intrusion and avoidance did not predict anxiety at follow-up. These results provide further evidence that intrusive memories are not simply an epiphenomenon of depression, but predict depression prospectively. Our results suggest that novel, depression-specific theories that emphasise the role of memory disturbances in the maintenance of depression are needed. 相似文献

One key issue for any computational model of visual word recognition is the choice of an input coding scheme for assigning letter position. Recent research has shown that transposed-letter similarity effects occur even when the transposed letters are not adjacent (caniso-casino; Perea & Lupker, 2004, JML). In the present study we conducted two single-presentation lexical decision experiments to examine whether transposed-letter effects occur at a syllable level. We tested two types of nonwords: (1) nonwords created by transposing two internal CV syllables (PRIVEMARA; the base word is primavera, the Spanish for spring) and (2) nonwords created by transposing two adjacent bigrams that do not form a syllable (PRIMERAVA). We also created the appropriate orthographic control conditions, in which the critical letters were replaced instead of being switched. Results showed that the transposition of two syllables or two adjacent bigrams produced a quite robust (and similar) transposed-letter effect. Thus, transposed-letter effects seem to occur at an early orthographic, graphemic level, rather than at a syllable level. We examine the implications of the observed results for the input coding schemes in visual word recognition. 相似文献

Previous spatial cuing studies have shown that the capture of spatial attention is contingent on top-down attentional control
settings whose specificity varies as a function of the certainty of the defining features of the target. For example, when
the target is a singleton defined by one specific color, observers adopt a control setting for that color. When the target
can be one of two possible colors, however, observers appear to adopt a control setting for color singletons in general (see,
e.g., Folk & Remington, 2008). The present study tested whether such results instead reflect the simultaneous maintenance
of control settings for multiple colors (Adamo, Pun, Pratt, & Ferber, 2008). Observers searched for targets that were unpredictably
red or green, preceded by spatial cues that were red, green, or blue. All three cue types produced evidence of capture, consistent
with a general set for color singletons rather than the maintenance of multiple control settings. 相似文献

This paper pools the language of psychoanalysis with other disciplines to illuminate the very real and ephemeral experience of working with patients who experience states of nonbeing. Using the powerful imagery of Francesca Woodman’s photographs, my patient and I enter the breach in her mind that trauma creates. Barthes, Benjamin, and art criticism enable me to relate to my patient’s condition of trying to exist suspended between life and death. 相似文献

The aim of this study was to examine developmental differences in autobiographical memory using a novel test that assesses its semantic and episodic subcomponents. Forty-two children aged 7-13 years were asked to recall semantic information and episodic events from three different time periods (current school year, last school year, and previous school years). For the recalls of all events, sense of remembering or sense of just knowing was measured via the Remember/Know paradigm. Age-related differences were observed for episodic autobiographical memory whereas semantic autobiographical memory was characterized by a relative developmental invariance. The increase with age was also found in the number of "Remember" responses and their justification in terms of the actual contextual information retrieved-factual, spatial, and, more especially, temporal details. These findings highlight developmental differences between the episodic and semantic subcomponents of autobiographical memory and support the view that mental 'time travel' through subjective time, which allows one to re-experience the past through self-awareness, is the last feature of autobiographical memory to become fully operational. 相似文献

Nonwords created by transposing two letters (e.g., RELOVUTION) are very effective at activating the lexical representation of their base words (Perea & Lupker, 2004). In the present study, we examined whether the nature of transposed-letter (TL) similarity effects was purely orthographic or whether it could also have a phonological component. Specifically, we examined transposed-letter similarity effects for nonwords created by transposing two nonadjacent letters (e.g., relovución-REVOLUCION) in a masked form priming experiment using the lexical decision task (Experiment 1). The controls were (a) a pseudohomophone of the transposed-letter prime (relobución-REVOLUCION; note that B and V are pronounced as /b/ in Spanish) or (b) an orthographic control (relodución-REVOLUCION). Results showed a similar advantage of the TL nonword condition over the phonological and the orthographic control conditions. Experiment 2 showed a masked phonological priming effect when the letter positions in the prime were in the right order. In a third experiment, using a single-presentation lexical decision task, TL nonwords produced longer latencies than the orthographic and phonological controls, whereas there was only a small phonological effect restricted to the error data. These results suggest that TL similarity effects are orthographic--rather than phonological--in nature. 相似文献

The present research uses a technique that permits unique estimation of both automatic and effortful processes in the question-behavior link. Results show that individuals asked to report behavioral intent (vs. those not asked) are more likely to choose options that are highly accessible and positively valenced, regardless of cognitive resources available at the time of processing. This suggests that the effect of intent questions on subsequent behavior is primarily the result of automatic, as opposed to effortful, processing. Practically, this suggests that efforts to debias this robust effect need to affect nonconscious processes and adjust for the automatic impact of being asked an intention question on respondents' behavior. 相似文献

Although everyday life is often demanding, it remains unclear how demanding conditions impact self‐regulation. Some theories suggest that demanding conditions impair self‐regulation, by undermining autonomy, interfering with skilled performance and working memory, and depleting energy resources. Other theories, however, suggest that demanding conditions improve self‐regulation by mobilizing super‐ordinate control processes. The present article integrates both kinds of theories by proposing that the self‐regulatory impact of demanding conditions depends on how people adapt to such conditions. When people are action‐oriented, demanding conditions may lead to improved self‐regulation. When people are state‐oriented, demanding conditions may lead to impaired self‐regulation. Consistent with this idea, action versus state orientation strongly moderates the influence of demands on self‐regulatory performance. The impact of demanding conditions on self‐regulation is thus not fixed, but modifiable by psychological processes. 相似文献
