During real-world scene viewing, humans must prioritize scene regions for attention. What are the roles of low-level image salience and high-level semantic meaning in attentional prioritization? A previous study suggested that when salience and meaning are directly contrasted in scene memorization and preference tasks, attentional priority is assigned by meaning (Henderson & Hayes in Nature Human Behavior, 1, 743–747, 2017). Here we examined the role of meaning in attentional guidance using two tasks in which meaning was irrelevant and salience was relevant: a brightness rating task and a brightness search task. Meaning was represented by meaning maps that captured the spatial distribution of semantic features. Meaning was contrasted with image salience, represented by saliency maps. Critically, both maps were represented similarly, allowing us to directly compare how meaning and salience influenced the spatial distribution of attention, as measured by fixation density maps. Our findings suggest that even in tasks for which meaning is irrelevant and salience is relevant, meaningful scene regions are prioritized for attention over salient scene regions. These results support theories in which scene semantics play a dominant role in attentional guidance in scenes. 相似文献

In an item-method directed forgetting task, attentional resources are withdrawn from forget item processing (e.g., Taylor & Fawcett in Attention, Perception, & Psychophysics, 73, 1790–1814, 2011). Taylor and Hamm (Attention, Perception, & Psychophysics, 78, 168–186, 2016) demonstrated that there is no corresponding increase in the proclivity for exogenous attention to be captured following a forget instruction. This means either that the attentional resources withdrawn from the forget item are reallocated immediately (and therefore not especially vulnerable to capture) or that it is not exogenous attention that is withdrawn. Given that endogenous attention is distinct from exogenous attention, we therefore extended the Taylor and Hamm study by using endogenous orienting rather than exogenous orienting. Words appeared individually in a peripheral location (Exp. 1) or in a central location (Exp. 2), followed by an instruction to either remember or forget. After a short (50-ms) or long (250-ms) interstimulus interval (ISI), a central cue (80% accurate) directed participants to allocate their attention to the left or right. This was followed by a discrimination target that appeared at a 1,000-ms cue–target stimulus onset asynchrony. A subsequent yes–no recognition test assessed memory for all study items. In both experiments, we observed better recognition of remember words than forget words—a directed forgetting effect. We also found a cueing effect, revealed as faster reaction times to discriminate cued targets than to discriminate uncued targets. There was not, however, an effect of memory instruction (and/or instruction–cue ISI) on the magnitude of this cueing effect. Thus, neither exogenous attention nor endogenous attention remains in an unengaged state following an instruction to forget. 相似文献

Causal modeling of relations among learning history, anxiety sensitivity, and panic attacks 总被引:3,自引:0,他引:3

We used structural equation modeling (SEM) to test the hypothesis that childhood instrumental and vicarious learning experiences influence frequency of panic attacks in young adulthood both directly, and indirectly through their effects on anxiety sensitivity (AS). A total of 478 university students participated in a retrospective assessment of their childhood learning experiences for arousal-reactive sensations (e.g., nausea, racing heart, shortness of breath, dizziness) and arousal-non-reactive sensations (i.e., colds, aches and pains, and rashes). SEM revealed that learning history for arousal-reactive somatic symptoms directly influenced both AS levels and panic frequency; AS directly influenced panic frequency; and learning history for arousal-non-reactive symptoms directly influenced AS but did not directly influence panic frequency. These results are consistent with the findings of previous retrospective studies on the learning history origins of AS and panic attacks, and provide the first empirical evidence of a partial mediation effect of AS in explaining the relation between childhood learning experiences and panic attacks in young adulthood. Implications for understanding the etiology of panic disorder are discussed. 相似文献

Bernard Williams distinguishes moral incapacities – incapacities that are themselves an expression of the moral life – from mere psychological ones in terms of deliberation. Against Williams I claim there are examples of such moral incapacity where no possible deliberation is involved – that an agent's incapacity may be a primitive feature or fact about their life. However Michael Clark argues that my claim here leaves the distinction between moral and psychological incapacity unexplained, and that an adequate understanding of the kind of examples I suggest must involve at least some implicit reference to deliberation. In this paper I attempt to meet Clark's objection and further clarify my account of primitive moral incapacities by considering an example from Mark Twain's Huckleberry Finn . What this example shows, I argue, is how our characterization of an agent's response as a moral incapacity turns not on the idea of deliberation but on the way certain primitive incapacities for action are connected to a larger pattern of response in an agent's life, a pattern of response that itself helps to constitute our conception of that agent's character and the moral life more generally. 相似文献

A survey conducted with university academics (N = 187) investigated self‐reported behaviour, explanations, social identification and perceptions of power during a period of industrial disputation. The results point to the importance of subjective experience of group memberships rather than overt group memberships in understanding behaviour and perceptions of power during industrial conflict and demonstrate very little support for the idea that industrial action or inaction reflects coerced behaviour.

The study was an examination of the relationship between sociotropy and excessive reassurance seeking in the prediction of depression. Although there is an obvious theoretical link between these constructs, little empirical work has been directed at integrating these constructs. Because it was theorized that sociotropic persons would be relatively more likely to engage in excessive reassurance seeking relative to autonomous individuals, it was predicted that sociotropy, and not autonomy, would be positively related to excessive reassurance seeking. In addition, it was predicted that excessive reassurance seeking would mediate effects of sociotropy upon depression. Overall, the results from 167 undergraduates completing measures for all variables supported these predictions. The results suggest that beyond the psychological vulnerabilities hypothesized by A. T. Beck (1983), sociotropic persons might engage in interpersonal behaviors that exacerbate their response to life stress. 相似文献

In two studies we investigated 3‐ to 5‐year‐old children’s ability to reverse ambiguous figures and the relation between this ability and the ability to understand multiple representations. Children never reversed before they were informed of the two alternative interpretations of the figures. Even when they were informed of the alternatives and understood that both were possible, 3‐year‐olds and most 4‐year‐olds did not reverse. In contrast, a majority of 5‐year‐olds did reverse. In general, children only reversed if they also passed a standard false belief task. However, there was a closer correlation between reversals and a ‘droodle’ task that involved an understanding of the ambiguity of perceptual representations. These results suggest that the immediate experience of reversal may depend on a more abstract understanding of ambiguous representations. 相似文献

Tone sequences with conflicting fundamental pitch and timbre changes are heard differently by musicians and nonmusicians 总被引:1,自引:0,他引:1

An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians. The AAT comprised different tone pairs, presented in both within-pair orders, in which overtone spectra rising in pitch were associated with missing fundamental frequencies (F0) falling in pitch, and vice versa. The F0 interval ranged from 2 to 9 semitones. The participants were instructed to decide whether the perceived pitch went up or down; no information was provided on the ambiguity of the stimuli. The majority of professionals classified the pitch changes according to F0, even at the smallest interval. By contrast, most nonmusicians classified according to the overtone spectra, except in the case of the largest interval. Amateurs ranged in between. A plausible explanation for the systematic group differences is that musical practice systematically shifted the perceptual focus from spectral toward missing-F0 pitch, although alternative explanations such as different genetic dispositions of musicians and nonmusicians cannot be ruled out.

This study examined the representational nature of configural response learning using a task that required simultaneous keypresses with 2 or 3 fingers, similar to the production of chords on the piano. If the benefits of learning are related to the retrieval of individual stimulus-response mappings, performance should depend on the frequencies of the individual responses forming each chord. Alternatively, learning may involve the encoding of configural information concerning the relationship between the chord elements. In Experiment 1, training was restricted to a subset of the 120 possible 3-element chords. Probe blocks included the practiced chords, chords composed of novel configurations of practiced elements (reconfigured), and chords that contained a new element (new). Practiced chords were performed faster than reconfigured chords, indicating learning involves the encoding of configural information. Experiment 2 showed that learning was not restricted to configurations within each hand. Experiments 3 and 4 demonstrated that learning was largely response based. 相似文献

At 24-months of age, toddlers (N=62) and their mothers were observed in a free-play session to determine the contribution of (a) maternal sensory sensitivity to positive and negative infant facial expressions as measured in a signal detection task at 6 months, (b) maternal behavior and affect, infant behavior and affect, and dyadic interaction at 9 months, and (c) infant attachment status at 12 months in predicting maternal, toddler, and dyadic measures at 24 months. Hierarchical regression analyses revealed that over and above early maternal behavior, which was predictive of later maternal behavior at 24 months, sensory sensitivity to the positive infant expression at 6 months predicted maternal behavior at 24 months and sensory sensitivity to both the positive and negative expression was associated with later maternal affect. Infant attachment status emerged as the variable which predicted toddler behavior and dyadic interaction at 24 months. 相似文献
