Societal Risk Perception Among Children, Adolescents, Adults, and Elderly People

This study reported on mean risk magnitude judgments expressed by French participants aged 8 to 75 years, on a set of 91 hazardous activities, substances, and technologies. It then systematically analyzed the effects of the age factor on the judgments. Between elderly people and young and mature adults, few notable differences were detected. The most important result was that a considerable proportion of the children were able to estimate the risk associated with most items of the present study, and that the linear association between children's ratings and adults' ratings was very high. This finding supports the view that the learning of the risk associated with various technologies, common in society, is a fast process, depending probably much more on exposure to media information and family discussions (socialization) than on exposure to everyday reality.     

网络词语与非网络词语的知觉差异:时间知觉、空间距离知觉与知觉范围

根据具身认知理论,人们的认知会受到身体活动的影响。网络环境下人的身体活动受到限制,因而其认知活动与非网络环境存在很大的差异。本研究目的在于考察人们对网络词语与非网络的日常词语的时间知觉,空间距离知觉与知觉范围是否有差异。结果发现被试对网络词语的时间知觉更长;网络词语的空间距离感与日常词语没有显著差异;在启动网络词语之后,被试的知觉范围缩小,对中心刺激的反应显著快于边缘刺激。本研究发现了网络词语加工在时间知觉和知觉范围上的变化。     

Language, Learning, and Color Perception

Abstract— People perceive colors categorically. But what is the role of the environment (or nurture)—specifically, language—in color perception? The effects of language on the way people categorize and perceive colors have been considered to be minimal, but recent evidence suggests that language may indeed change color perception. Speakers of languages with different color-name repertoires show differences in the way they perceive color. Research shows that categorical effects on color perception can be induced through laboratory training and suggests language can similarly change color perception through the mechanism of perceptual learning.     

Voice,speech, and language: selected papers from APCAM

ABSTRACT

This special issue features selected papers from the 13th annual Auditory Perception, Cognition, and Action Meeting (APCAM). APCAM is a unique meeting in its focus on the perceptual, cognitive, and behavioural aspects of audition. The meeting is held each year just before the Annual Meeting of the Psychonomic Society.     

Duration discrimination in the context of age,sex, and cognition

It has been proposed that the perception of very short duration is governed by sensory mechanisms, whereas the perception of longer duration depends on cognitive capacities. Four duration discrimination tasks (modalities: visual, auditory; base duration: 100 ms, 1000 ms) were used to study the relation between time perception, age, sex, and cognitive abilities (alertness, visual and verbal working memory, general fluid reasoning) in 100 subjects aged between 21 and 84 years. Temporal acuity was higher (Weber fractions are lower) for longer stimuli and for the auditory modality. Age was related to the visual 100 ms condition only, with lower temporal acuity in elder participants. Alertness was significantly related to auditory and visual Weber fractions for shorter stimuli only. Additionally, visual working memory was a significant predictor for shorter visual stimuli. These results indicate that alertness, but also working memory, are associated with temporal discrimination of very brief duration.     

Depression,self-focus,and social interaction

The accuracy of depressed and nondepressed subjects' perceptions of their own and a social interactional partner's performance was investigated. Twenty depressed and twenty nondepressed college students participated in dyadic interactions and then rated their own and their partner's social behavior. The interactions were also rated by objective coders. Depressed subjects were differentiated from nondepressed subjects on several measures by both the coders and the subjects. Depressed subjects' self-ratings were correlated with the coders' ratings more often than were the nondepressives' ratings, suggesting depressives provided more accurate self-observations. Contrary to prediction, depressives were also more accurate in judging their partner's behavior. Depressives experienced heightened levels of self-focused attention, but this attentional focus did not mediate the relationship between depression level and self-accuracy. Finally, an analysis of the verbal statements suggests that performance differences between depressives and nondepressives may be a function of the quantity, rather than the quality, of the verbal production.     

Estimates of shape by eye, or, The little invariant that could

Five experiments were conducted to test the hypothesis that observers apprehend specific constancies under change in perspective. The constancies were projective properties of ellipses pictured to slant and tilt in depth. Observers were asked to reproduce the static upright view of a moving pair of ellipses, using a computer graphics display and interface. Projective invariants for pairs of conics were computed on the observers’ productions. A few experimental conditions revealed near-perfect performance. When pairs of coplanar ellipses were viewed under dynamic transformation in perspective, then invariants calculated on the observers’ productions were a match – in value on average – to the invariants of the transforming ellipse pairs. It is proposed that measures of projective properties afford a family of techniques that can be applied to gauge acuity for complex shapes in the study of visual form perception.     

感性追求与特立独行——魏晋南北朝的士风

魏晋南北朝时期，由于战争频仍，政治险恶，生命危浅，在士族群体（泛指有士族身份或士族背景的人）中形成了一股追求感性欲望之满足的享乐之风以及蔑视礼法、特立独行的行为方式。这种士风，从积极方面言，是人的生命的某种程度的解放和个性的自觉；从消极方面言，则对社会风气的堕落以及人的社会责任感的淡化起着推波助浪的作用。     

Trait impressions from voices: Considering multiple ‘origin stories’ and the dynamic nature of trait-related cues

Experimental findings for trait impressions from voices are often discussed in relation to potential evolutionary origins. This commentary takes Sutherland and Young's (2022) account of the different potential origins of facial trait impressions to suggest that vocal trait impressions should also be viewed as having been shaped by cultural and individual learning.     

How optimists face skin cancer information: Risk assessment,attention, memory,and behavior

The purpose of the present study was to investigate how optimists process health-related information. Sixty-five young adults (ages 18–35) reported skin cancer-related knowledge and behaviors, and read slides of information on skin and skin cancer. Visual attention to the slides was recorded using eye tracking, and their memory for the information was measured. Additionally, participants’ self-reported skin cancer-relevant behavior was assessed prospectively in the months following the lab component of the study. Results show that individuals low in dispositional optimism or high in health-related optimism paid more attention when they were at high objective risk of developing skin cancer; and individuals high in dispositional optimism or high in health-related optimism were more likely to perform adaptive, health-promoting behaviors. In addition, optimistic beliefs were found not to be related with unrealistic optimism. Dispositional and health-related optimism therefore appear to predict health-related cognition and behavior in distinct ways.     

Effects of Attire, Alcohol, and Gender on Perceptions of Date Rape

This investigation explored three categories of college students’ perceptions of sexual assault: perceptions of similarity to vignette characters, perceptions of vignette characters’ sexual intent, and victim-blaming behaviors, using a convenience sample of 652 U.S. undergraduates and an on-line factorial survey containing a two-part heterosexual date rape vignette. This investigation predicted that vignette character attire, character alcohol use, and participant gender would each significantly influence perceptions in all three categories. Strong associations appeared between all three experimental variables and perceptions, with characters that wore suggestive attire or became intoxicated perceived as less similar and having greater sexual intent than characters that wore neutral attire or abstained. Few differences in actual victim-blaming appeared, likely because of the elimination of hindsight bias.     

Color charts, esthetics, and subjective randomness

Color charts, or grids of evenly spaced multicolored dots or squares, appear in the work of modern artists and designers. Often the artist/designer distributes the many colors in a way that could be described as "random," that is, without an obvious pattern. We conduct a statistical analysis of 125 "random-looking" art and design color charts and show that they differ significantly from truly random color charts in the average distance between adjacent colors. We argue that this attribute generalizes results in subjective randomness in a black/white setting and gives further evidence supporting a connection between subjective randomness and what is esthetically pleasing.     

VIRTUE, EMOTION, AND ATTENTION

Abstract: The perceptual model of emotions maintains that emotions involve, or are at least analogous to, perceptions of value. On this account, emotions purport to tell us about the evaluative realm, in much the same way that sensory perceptions inform us about the sensible world. An important development of this position, prominent in recent work by Peter Goldie amongst others, concerns the essential role that virtuous habits of attention play in enabling us to gain perceptual and evaluative knowledge. I think that there are good reasons to be sceptical about this picture of virtue. In this essay I set out these reasons, and explain the consequences this scepticism has for our understanding of the relation between virtue, emotion, and attention. In particular, I argue that our primary capacity for recognizing value is in fact a non-emotional capacity.     

Quiet Eye Duration,Expertise, and Task Complexity in Near and Far Aiming Tasks

Skilled (n = 12) and less skilled (n = 12) billiards players participated in 2 experiments in which the relationship between quiet eye duration, expertise, and task complexity was examined in a near and a far aiming task. Quiet eye was defined as the final fixation on the target prior to the initiation of movement. In Experiment 1, skilled performers exhibited longer fixations on the target (quiet eye) during the preparation phase of the action than their less skilled counterparts did. Quiet eye duration increased as a function of shot difficulty and was proportionally longer on successful than on unsuccessful shots for both groups of participants. In Experiment 2, participants executed shots under 3 different time-constrained conditions in which quiet eye periods were experimentally manipulated. Shorter quiet eye periods resulted in poorer performance, irrespective of participant skill level. The authors argue that quiet eye duration represents a critical period for movement programming in the aiming response.     

An effect of mood on the perception of geographical slant

Previous research has shown that hills appear steeper to those who are fatigued, encumbered, of low physical fitness, elderly, or in declining health (Bhalla & Proffitt, 1999; Proffitt, Bhalla, Gossweiler, & Midgett, 1995). The prevailing interpretation of this research is that observers’ perceptions of the environment are influenced by their capacity to navigate that environment. The current studies extend this programme by investigating more subtle embodied effects on perception of slant; namely those of mood. In two studies, with two different mood manipulations, and two estimates of slant in each, observers in a sad mood reported hills to be steeper. These results support the role of mood and motivational factors in influencing spatial perception, adding to the previous work showing that energetic potential can influence perception.     

A systematic, large-scale study of synaesthesia: implications for the role of early experience in lexical-colour associations

For individuals with synaesthesia, stimuli in one sensory modality elicit anomalous experiences in another modality. For example, the sound of a particular piano note may be 'seen' as a unique colour, or the taste of a familiar food may be 'felt' as a distinct bodily sensation. We report a study of 192 adult synaesthetes, in which we administered a structured questionnaire to determine the relative frequency and characteristics of different types of synaesthetic experience. Our data suggest the prevalence of synaesthesia in the adult population is approximately 1 in 1150 females and 1 in 7150 males. The incidence of left-handedness in our sample was within the normal range, contrary to previous claims. We did, however, find that synaesthetes are more likely to be involved in artistic pursuits, consistent with anecdotal reports. We also examined responses from a subset of 150 synaesthetes for whom letters, digits and words induce colour experiences ('lexical-colour' synaesthesia). There was a striking consistency in the colours induced by certain letters and digits in these individuals. For example, 'R' elicited red for 36% of the sample, 'Y' elicited yellow for 45%, and 'D' elicited brown for 47%. Similar trends were apparent for a group of non-synaesthetic controls who were asked to associate colours with letters and digits. Based on these findings, we suggest that the development of lexical-colour synaesthesia in many cases incorporates early learning experiences common to all individuals. Moreover, many of our synaesthetes experienced colours only for days of the week, letters or digits, suggesting that inducers that are part of a conventional sequence (e.g. Monday, Tuesday, Wednesday...; A, B, C...; 1, 2, 3...) may be particularly important in the development of synaesthetic inducer-colour pairs. We speculate that the learning of such sequences during an early critical period determines the particular pattern of lexical-colour links, and that this pattern then generalises to other words.     

Intersensory Redundancy Guides the Development of Selective Attention, Perception, and Cognition in Infancy

Abstract— That the senses provide overlapping information for objects and events is no extravagance of nature. This overlap facilitates attention to critical aspects of sensory stimulation, those that are redundantly specified, and attenuates attention to nonredundantly specified stimulus properties. This selective attention is most pronounced in infancy and gives initial advantage to the perceptual processing of, learning of, and memory for stimulus properties that are redundant, or amodal (e.g., synchrony, rhythm, and intensity), at the expense of modality-specific properties (e.g., color, pitch, and timbre) that can be perceived through only one sense. We review evidence supporting this hypothesis and discuss its implications for theories of perceptual, cognitive, and social development.     

The relationship between auditory temporal processing,phonemic awareness,and reading disability

Recent research suggests an auditory temporal deficit as a possible contributing factor to poor phonemic awareness skills. This study investigated the relationship between auditory temporal processing of nonspeech sounds and phonological awareness ability in children with a reading disability, aged 8-12 years, using Tallal's tone-order judgement task. Normal performance on the tone-order task was established for 36 normal readers. Forty-two children with developmental reading disability were then subdivided by their performance on the tone-order task. Average and poor tone-order subgroups were then compared on their ability to process speech sounds and visual symbols, and on phonological awareness and reading. The presence of a tone-order deficit did not relate to performance on the order processing of speech sounds, to poorer phonological awareness or to more severe reading difficulties. In particular, there was no evidence of a group by interstimulus interval interaction, as previously described in the literature, and thus little support for a general auditory temporal processing difficulty as an underlying problem in poor readers. In this study, deficient order judgement on a nonverbal auditory temporal order task (tone task) did not underlie phonological awareness or reading difficulties.     

Perception,Memory, and Duration: The Binding Problem and the Synthesis of the Past

Theories of perception and of memory are closely allied. The binding problem (which considers how bits of perception are reassembled by the brain) leads to neurophysiological subjectivism. This could be outflanked by arguing with Bergson that perceiving consciousness is out in the world. Thus the brain would bind only behavioral “maps.” In turn, consciousness would retain our personal pasts. Such personal (episodic) memories both help us to recognize present objects and to perform creative acts. Memory, although retentive, is also creative. This is important in rethinking biological and evolutionary memory.
