A dynamic touch paradigm in which participants judged the lengths of rods and pipes was used to test the D. M. Jacobs and C. F. Michaels (2007) theory of perceptual learning. The theory portrays perception as the exploitation of a locus on an information manifold and learning as continuous movement across that manifold to a new locus, as guided by information available in feedback. The information manifold was defined as a 1-dimensional space of inertial variables. To encourage maximal learning, a 2-step procedure was used in each of 2 experiments. Each step comprised a pretest to identify the starting locus on the information manifold, a practice phase in which feedback specifying the optimal locus was given, and a posttest in which the ending locus on the manifold was identified. In the 2nd step, a different feedback variable specified a different optimum. In both experiments, participants, who sometimes began at different loci, showed the predicted movement toward the optimum in each phase. Whereas previous applications of the theory posit the existence of information-for-learning without identifying a candidate variable, such a candidate is identified. 相似文献

George H. Mead and Alfred Schutz proposed foundations for an interpretative sociology from opposite standpoints. Mead accepted
the objective meaning structure a priori. His problem became therefore the explanation of the individuality and creativity
of human actors in his social behavioristic approach. In contrast, Schutz started from the subjective consciousness of an
isolated actor as a result of a phenomenological reduction. He was concerned with the problem of explaining the possibility
of this isolated actor’s perceiving other actors in their existence, their concreteness, and the motives for their behavior.
I treat these two approaches and their associated problems as equally relevant. My evaluation is based on their success in
solving their specific problems. The aim is to decide which of the two approaches provides the more adequate foundation for
an interpretative sociology.

Traditional models of face perception (e.g. Bruce and Young 1986) stress independent routes for processing identity and emotional expression. We investigated the interplay between familiarity and emotional expression by systematically varying both factors. In contrast to earlier studies which used binary forced-choice decisions, participants had to judge the familiarity of the presented face and the emotional hedonic valence and emotional arousal of its expressed emotion (angry, happy or neutral), using rating scales. The results demonstrated symmetric, strong interactions between familiarity and expressed emotion. Thus, this study supports more recent models of face perception (Haxby et al. 2000) that were mostly based on brain imaging data. These data together with our behavioural results emphasize the interaction of emotional expression and personal identity and support approaches that propose a relative segregation of these processes, rather than completely independent coding (Calder and Young 2005). 相似文献

Our research examines whether intersecting racial and gender identities affect person perception. Predominantly White undergraduates (292) from a large northeastern U.S. university categorized and rated pictures (Study 1) and videos (Study 2) of Black and White men and women. We supported three hypotheses: 1) intersectionality affects person perception processes, leading to gender categorization errors for Black women; 2) “Blackness” and “maleness” are highly associated for Black male and female targets; and, 3) women are perceived as unattractive proportionally to their perceived masculinity, leading Black women to be rated as less attractive than other women. We suggest that intersectional approaches are required in order to fully understand person perception. Further, the Black/male association may lead to unique harms for Black women. 相似文献

The predictive validity of symptom criteria for different subtypes of ADHD among children who were impaired in at least one
setting in early childhood was examined. Academic achievement was assessed seven times over 8 years in 125 children who met
symptom criteria for ADHD at 4–6 years of age and in 130 demographically-matched non-referred comparison children. When intelligence
and other confounds were controlled, children who met modified criteria for the predominantly inattentive subtype of ADHD
in wave 1 had lower reading, spelling, and mathematics scores over time than both comparison children and children who met
modified criteria for the other subtypes of ADHD. In some analyses, children who met modified criteria for the combined type
had somewhat lower mathematics scores than comparison children. The robust academic deficits relative to intelligence in the
inattentive group in this age range suggest either that inattention results in academic underachievement or that some children
in the inattentive group have learning disabilities that cause secondary symptoms of inattention. Unexpectedly, wave 1 internalizing
(anxiety and depression) symptoms independently predicted deficits in academic achievement controlling ADHD, intelligence,
and other predictors. 相似文献

To estimate the prevalence of being well-adjusted in adolescence, boys and girls with (n = 96) and without (n = 126) attention-deficit/hyperactivity disorder (ADHD) were assessed seven times in eight years starting when they were 4–6 years
of age. Symptoms of ADHD, ODD/CD, and depression/anxiety in addition to social skills and social preference were gathered
using multiple methods and informants. Being well-adjusted was defined by surpassing thresholds in at least four of the five
domains. At the 7- and 8-year follow-up, when youth were 11–14 years old, probands were significantly less likely to be well-adjusted
relative to age- and ethnicity-matched control children. Only a minority of children with ADHD was well-adjusted in adolescence
when emotional, behavioral, and social domains were considered simultaneously. Even when their ADHD symptoms improved over
time, most probands exhibited significant impairment 7–8 years after their initial assessment. 相似文献

Recent studies suggest that most of what parents know about their adolescent offspring's whereabouts and companions is the result of youth disclosure, rather than information gained through active parental monitoring. This raises the possibility that parental knowledge is spuriously correlated with youth delinquency solely because the most delinquent youth disclose the least information to parents (because they have the most to hide). We tested this spurious association hypothesis using prospective data on offspring of a nationally representative sample of US women, controlling demographic and contextual covariates. In separate analyses, greater parental knowledge of their offspring's peer associations at both 12-13 years and at 14-15 years was associated with lower odds of being in the top 1 standard deviation of youth-reported delinquency at 16-17 years, controlling for delinquency at the earlier ages. The extent to which parents set limits on activities with peers at 14-15 years did not mediate or moderate the association between parental knowledge and delinquency, but it did independently predict future delinquency among adolescents living in high-risk neighborhoods. This suggests that the association between parental knowledge and future delinquency is not solely spurious; rather parental knowledge and limit setting are both meaningful predictors of future delinquency. 相似文献

There is abundant evidence from behavioral and neurophysiological experiments for the distinction of natural versus artifactual categories and a gender-specific difference: women’s performances in cognitive tasks increase when natural categories are used, whereas men’s performances increase with artifactual categories. Here, we used the semantic priming paradigm to study retrieval processes by presenting category labels as primes and exemplars as targets. Overall, in two experiments we found larger priming effects for natural than for artifactual categories. In addition, females showed positive priming effects for natural but negative effects for artifactual categories, whereas males showed positive priming effects for both categories. This pattern matches with that from other tasks and can be interpreted as evidence that the findings from these other tasks are, at least partially, indeed due to different representations or processing modes for males and females and not (exclusively) due to—for example—different familiarity with a category. In a further experiment, we showed that the found pattern for females can be manipulated by focusing on perceptual vs. functional features. The results can be interpreted as first evidence that there are (eventually in addition to different “crystallized” semantic structures) specific default processing modes that differ for males and females. 相似文献

In the paradigm of repeated masked semantic priming (Wentura & Frings. 2005), prime and mask are repeatedly and rapidly interchanged. Using this technique in a semantic priming task with category labels as primes and category exemplars as targets (related, e.g.. BIRD - swan --> BIRD - finch; unrelated, e.g., BIRD - lily --> FRUIT - finch), Wentura and Frings found a negatively signed priming effect. Here we used the repeated masking technique with category exemplars as targets and primes (i.e., identity priming) for analyzing, whether this effect reflects center-surround or spreading inhibition. If the repeated masked technique reflects spreading inhibition, a negative effect should also appear for identity priming. In contrast, a center-surround approach would predict a positive effect. In accordance with the latter hypothesis, we found a significant positive effect in identity priming (Experiment 1a) and significant difference to the negatively signed semantic priming effect when primes were category labels (Experiment 1b). This is indicative of the repeated masked semantic priming effect being a negatively signed semantic priming effect due to a center-surround mechanism. 相似文献

Faces are of essential importance for human social life. They provide valuable information about the identity, expression, gaze, health, and age of a person. Recent face‐processing models assume highly interconnected neural structures between different temporal, occipital, and frontal brain areas with several feedback loops. A selective deficit in the visual learning and recognition of faces is known as prosopagnosia, which can be found both in acquired and congenital form. Recently, a hereditary sub‐type of congenital prosopagnosia with a very high prevalence rate of 2.5% has been identified. Recent research results show that hereditary prosopagnosia is a clearly circumscribed face‐processing deficit with a characteristic set of clinical symptoms. Comparing face processing of people of prosopagnosia with that of controls can help to develop a more conclusive and integrated model of face processing. Here, we provide a summary of the current state of face processing research. We also describe the different types of prosopagnosia and present the set of typical symptoms found in the hereditary type. Finally, we will discuss the implications for future face recognition research. 相似文献
