Many concepts have stereotypes. This leaves open the question of whether concepts are stereotypes. It has been argued elsewhere that theories that identify concepts with their stereotypes or with stereotypical properties of their instances (e.g., Rosch, E. (1978). Principles of categorization. In E. Rosch & B. B. Lloyd (Ed.), Cognition and Categorization. Hillsdale, NJ: Lawrence Erlbaum Associates; Smith, E. E., Medin, D. L. (1981). Categories and Concepts. Cambridge, MA: Harvard University Press.) fail to provide an adequate account of the compositionality of concepts (Fodor, J., Lepore, E. (1996). The red herring and the pet fish: Why concepts still cannot be prototypes. Cognition, 58, 253-270.; Fodor, J. (1998). Concepts: Where cognitive science went wrong. New York, NY: Oxford University Press.). This paper extends this argument and reports an experiment suggesting that participants do not assume, even as a default strategy, that complex concepts inherit the stereotypes of their constituents. Thus propositions such as "Baby ducks have webbed feet" were judged to be less likely to be true than propositions like "Ducks have webbed feet." Moreover, manipulation of the type and number of noun phrase modifiers revealed a systematic departure from the unmodified noun's stereotype both with the addition of stereotypical modifiers ("Quacking ducks have webbed feet" versus "Ducks have webbed feet") and with the addition of a second modifier ("Baby Peruvian ducks have webbed feet" versus "Baby ducks have webbed feet"). Thus, in the general case the stereotypical properties of a head noun are systematically discounted when that head noun combines with modifiers. This effect represents a general principle of conceptual combination that argues against the inheritance of stereotypical features of concepts as a default strategy. Instead, we advocate a model of conceptual combination where concepts remain inert under combination, supported by a separate machinery that introduces pragmatic and knowledge-dependent inferences. 相似文献

The current investigation assessed the effectiveness of protective equipment, specifically arm splints, in reducing the occurrence of severe self-injurious behavior (SIB). Although the protective equipment reduced rates of SIB to near-zero levels, self-restraint subsequently emerged. In an attempt to reduce self-restraint while maintaining reductions in SIB, we provided noncontingent access to preferred stimuli. The presentation of preferred stimuli along with the use of protective equipment reduced both the rate of SIB and the duration of self-restraint. 相似文献

Fluctuations of ovarian hormones across the menstrual cycle influence a variety of social and cognitive behaviors in primates.
For example, female rhesus monkeys exhibit heightened interest for males and increased agonistic interactions with other females
during periods of high estrogen levels. In the present study, we hypothesized that females’ preference for males during periods
of high estrogen levels is also expressed at the level of face perception. We tested four intact females on two face-tasks
involving neutral portraits of male and female rhesus monkeys, chimpanzees and humans. In the visual preference task (VP),
monkeys had to touch a button to view a face image. The image remained on the screen as long as the button was touched, and
the duration of pressing was taken as an index of the monkey's looking time for the face stimulus. In the Face-Delayed Recognition
Span Test (Face-DRST), monkeys were rewarded for touching the new face in an increasing number of serially presented faces.
Monkeys were tested 5 days a week across one menstrual cycle. Blood was collected every other day for analysis of estradiol
and progesterone. Two of the four females were cycling at the time of testing. We did not find an influence of the cycle on
Face-DRST, likely due to a floor effect. In the VP however, the two cycling individuals looked longer at conspecific male
faces than female faces during the peri-ovulatory period of the cycle. Such effects were absent for human and chimpanzee faces
and for the two noncycling subjects. These data suggest that ovarian hormones may influence females’ preferences for specific
faces, with heightened preference for male faces during the peri-ovulatory period of the cycle. Heightened interest for stimuli
of significant reproductive relevance during periods of high conception risk may help guide social and sexual behavior in
the rhesus monkey. 相似文献

Toxic stressors (e.g., parental violence, depression, low income) place children at risk for insecure attachment. Parental reflective function—parents’ capacity to understand their own and their child's mental states and thus regulate their own feelings and behavior toward their child—may buffer the negative effects of toxic stress on attachment. Our objective was to test the effectiveness of the Attachment and Child Health (ATTACH) intervention, focusing on improving reflective function and children's attachment security, for at-risk mothers and children <36 months of age. Three pilot studies were conducted with women and children from an inner city agency serving vulnerable, low-income families and a family violence shelter. Randomized control trial (n = 20, n = 10 at enrollment) and quasi-experimental (n = 10 at enrollment) methods tested the effect of the ATTACH intervention on the primary outcome of reflective function scores, from transcribed Parent Development Interviews. Our secondary outcome was children's attachment patterns from Ainsworth's Strange Situation Procedure. Despite some attrition, mixed methods analysis of covariance and t tests revealed significant differences in maternal, child, and overall reflective function, with moderate effect sizes. While more children whose mothers received the ATTACH program were securely attached posttreatment, as compared with controls, significant differences were not observed, which may be due to missing observations (n = 5 cases). Understanding the effectiveness of programs like the ATTACH intervention contributes to improved programs and services to promote healthy development of children affected by toxic stress. 相似文献

Functional analyses sometimes do not identify momentary fluctuations in the function of destructive behavior (Bowman, Fisher, Thompson, & Piazza, 1997). In such cases, individuals may mand for the reinforcer that is currently most preferred and display destructive behavior if that mand goes unreinforced. In this study, we conducted a mand analysis to test whether destructive behavior functioned as a precurrent response that increased reinforcement for the participant's mands. We then evaluated a treatment that matched this function of destructive behavior by providing differential or time-based reinforcement of participant mands in accordance with multiple or chained schedules with reinforcement-schedule thinning. Decreases in destructive behavior averaged 97.4% across cases. We discuss these results relative to the importance of matching treatments for destructive behavior to operant functions for both traditional and idiosyncratic functions of destructive behavior. 相似文献

Resurgence occurs when a previously extinguished behavior reemerges once a more recently reinforced behavior is placed on extinction. Previous research has suggested that nontargeted responses within the same response class recur alongside target-response resurgence (e.g., da Silva, Maxwell, & Lattal, 2008; Lieving, Hagopian, Long, & O'Connor, 2004). The purpose of this two-experiment investigation was to examine target response resurgence while simultaneously measuring the occurrence of nontargeted responses. Three children diagnosed with autism spectrum disorder who displayed multiple topographies of problem behavior participated. In Experiment 1, a three-phase resurgence procedure was conducted and all three participants displayed target-response resurgence accompanied by the emergence of nontargeted forms of problem behavior. These findings were replicated in Experiment 2 using a 30-min assessment procedure. The implications of these findings as they pertain to the treatment of severe problem behavior and utility of a brief relapse assessment are discussed. 相似文献

This research investigated the congruence between the ideologies of political parties and the ideological preferences (N = 1515), moral intuitions (N = 1048), and political values and worldviews (N = 1345) of diverse samples of Swedish adults who voted or intended to vote for the parties. Logistic regression analyses yielded support for a series of hypotheses about variations in ideology beyond the left–right division. With respect to social ideology, resistance to change and binding moral intuitions predicted stronger preference for a social democratic (vs. progressive) party on the left and weaker preference for a social liberal (vs. social conservative or liberal-conservative) party on the right. With respect to political values and broader worldviews, normativism and low acceptance of immigrants predicted the strongest preference for a nationalist party, while environmentalism predicted the strongest preference for a green party. The effects were generally strong and robust when we controlled for left–right self-placements, economic ideology, and demographic characteristics. These results show that personality variation in the ideological domain is not reducible to the simplistic contrast between ‘liberals’ and ‘conservatives’, which ignores differences between progressive and non-progressive leftists, economic and green progressives, social liberal and conservative rightists, and nationalist and non-nationalist conservatives. 相似文献

The research was conducted to determine whether temperamental characteristics of neonates influence caregiver behavior as early as the second day of life. Visual attentiveness, activity, and irritability of 28 healthy newborns were rated during six 30-minute sessions. Derived scores represented the infant's behavior during the total observation time and during specified caretaking activities. Several categories of nurturant behaviors and types of comments directed toward each infant by nurse-caregivers were coded during independent sessions. Variations in caregiver behavior were shown by Pearson correlations to be related to independently assessed differences among neonates. Alert babies received the most nurturant and social contact; active infants received the least contact, but the most comments that reflected concern about their health; irritable infants were soothed most. The data clearly suggest that emerging infant temperament plays a role in shaping the caregiving environment by the second day of life. 相似文献
