It has recently been stated that exogenous attention impairs temporal-resolution tasks (Hein, Rolke, & Ulrich, 2006; Rolke, Dinkelbach, Hein, & Ulrich, 2008; Yeshurun, 2004; Yeshurun & Levy, 2003). In comparisons of performance on spatially cued trials versus neutral cued trials, the results have suggested that spatial attention decreases temporal resolution. However, when performance on cued and uncued trials has been compared in order to equate for cue salience, typically speed—accuracy trade-offs (SATs) have been observed, making the interpretation of the results difficult. In the present experiments, we aimed at studying the effect of spatial attention in temporal resolution while using a procedure to control for SATs. We controlled reaction times (RTs) by constraining the time to respond, so that response decisions would be made within comparable time windows. The results revealed that when RT was controlled, performance was impaired for cued trials as compared with neutral trials, replicating previous findings. However, when cued and uncued trials were compared, performance was actually improved for cued trials as compared with uncued trials. These results suggest that SAT effects may have played an important role in the previous studies, because when they were controlled and measured, the results reversed, revealing that exogenous attention does improve performance on temporal-resolution tasks. 相似文献

Classification of faces as to their sex or their expression—with sex and expression varying orthogonally—was studied in three experiments. In Experiment 1, expression classification was influenced by sex, with angry male faces being classified faster than angry female faces. Complementarily, sex classification was faster for happy than for angry female faces. In Experiment 2, mutual interaction of sex and expression was also found when the participants were asked to classify top and bottom face segments. In Experiment 3, a face inversion effect was found for both sex and expression classification of whole faces. However, a symmetrical interaction between sex and expression was again found. The results are discussed in terms of configural versus feature processing in the perception of face sex and expression and of their relevance to face perception models that postulate independent processing of different facial features. 2009 The Psychonomic Society, Inc. 相似文献

In the present study, we used the Deese/Roediger-McDermott paradigm to analyze the relationship between theme identifiability
of word lists and false memories in adults and children. We conducted two normative studies to determine the identifiability
levels for critical unpresented words in 40 associative lists in adults and in 16 associative lists in children. Then, in
three experiments, false memories for critical words that were either easy or hard to identify were analyzed in adults and
in children 4–5 years old and 11–12 years old. Opposite results were found for adults and children. Lists with highly identifiable
critical words produced fewer false memories for adults but more false memories for children. These results suggest that,
if they can identify critical words, adults use an identify-to-reject strategy to edit out false memories, whereas, in children,
theme identification does not lead to the use of such a monitoring strategy. 相似文献

Many animal species that rely mainly on calls to communicate produce individual acoustic structures, but we wondered whether
individuals of species better known as visual communicants, with small vocal repertoires, would also exhibit individual distinctiveness
in calls. Moreover, theoretical advances concerning the evolution of social intelligence are usually based on primate species
data, but relatively little is known about the social cognitive capacities of non-primate mammals. However, some non-primate
species demonstrate auditory recognition of social categories and possess mental representation of their social network. Horses
(Equus caballus) form stable social networks and although they display a large range of visual signals, they also use long-distance whinny
calls to maintain contact. Here, we investigated the potential existence of individual acoustic signatures in whinny calls
and the ability of horses to discriminate by ear individuals varying in their degree of familiarity. Our analysis of the acoustic
structure of whinnies of 30 adult domestic horses (ten stallions, ten geldings, ten mares) revealed that some of the frequency
and temporal parameters carried reliable information about the caller’s sex, body size and identity. However, no correlations
with age were found. Playback experiments evaluated the behavioural significance of this variability. Twelve horses heard
either control white noise or whinnies emitted by group members, familiar neighbours or unfamiliar horses. While control sounds
did not induce any particular response, horses discriminated the social category of the callers and reacted with a sound-specific
behaviour (vigilance and attraction varied with familiarity). Our results support the existence of social knowledge in horses
and suggest a process of vocal coding/decoding of information. 相似文献

The symptom patterns of 180 women with prospectively confirmed late luteal-phase dysphoric disorder (LLPDD) were examined using a careful application of factor and cluster analytic techniques. Factor analysis of premenstrual change scores on 33 common premenstrual syndrome symptoms yielded four orthogonal factors that were consistent across two sets of menstrual cycle data. These were a negative affect dimension with concomitant behavioral changes, physical symptoms, agitation, and positive arousal. Cluster analysis of factor scores grouped patients into one of five symptom patterns, the most common of which is a general distress cluster, characterized by symptoms across all dimensions. The LLPDD symptom groups identified are remarkably consistent with those of earlier studies using both normative and clinic samples, and consideration of symptom pattern differences in future research may greatly increase our understanding of this disorder. 相似文献

Using a 1-year prospective design, this study examined the influence of family status variables (family income, parental education, family structure), parenting variables (maternal support and restrictive control), peer support, and neighborhood risk on the school performance of 120 African American junior high school students. In addition to main effects of these variables, neighborhood risk was examined as a moderator of the effects of parenting and peer support. Family status variables were not predictive of adolescent school performance as indexed by self-reported grade point average. Maternal support at Time 1 was prospectively related to adolescent grades at Time 2. Neighborhood risk was related to lower grades, while peer support predicted better grades in the prospective analyses. Neighborhood risk also moderated the effects of maternal restrictive control and peer support on adolescent grades in prospective analyses. These findings highlight the importance of an ecological approach to the problem of academic underachievement within the African American community. 相似文献

Disjunctive inferences are difficult. According to the theory of mental models, it is because of the alternative possibilities to which disjunctions refer. Three experiments corroborated further predictions of the mental model theory. Participants judged that disjunctions, such as Either this year is a leap year or it is a common year are true. Given a disjunction such as Either A or B, they tended to evaluate the four cases in its ‘partition’: A and B, A and not‐B, not‐A and B, not‐A and not‐B, as ‘possible’ or ‘impossible’ in ways that bore out the difference between inclusive disjunctions (‘or both’) and exclusive disjunctions (‘but not both’). Knowledge usually concerns what is true, and so when participants judge that a disjunction is false, or contingent, and evaluate the cases in its partition, they depend on inferences that yield predictable errors. They tended to judge that disjunctions, such as follows: Either the food is cold or else it is tepid, but not both, are true, though in fact they could be false. They tended to infer ‘mirror‐image’ evaluations that yield the same possibilities for false disjunctions as those for true disjunctions. The article considers the implications of these results for alternative theories based on classical logic or on the probability calculus. 相似文献

The relationship between personality and well-being is dynamic and therefore should be examined within aging perspective. In study presented here we compared the prediction of well-being from personality in two samples?C223 adolescents attending high-school (16?C19?years; M?=?16.94, SD?=?0.51) and 134 older adults (54?C90?years; M?=?77.20, SD?=?7.39) living in retirement home or at home. Different aspects of well-being were included in the study. Subjective well-being was measured with Index of Well-Being, but also self-esteem and loneliness were included as measures of psychological well-being. Personality (measured with FFPI; Hendriks et al. in Pers Individ Dif 27:307?C325, 1999) significantly predicted indicators of well-being (Self-Esteem, Loneliness and Index of Well-Being) in both samples, with emotional stability and extraversion as most pronounced predictors. Personality explained more variance of well-being in adolescents than in older adults, and more variance in eudaimonic than hedonic aspects of well-being. 相似文献
