Research reported here concerns neural processes relating to stimulus equivalence class formation. In Experiment 1, two types of word pairs were presented successively to normally capable adults. In one type, the words had related usage in English (e.g., uncle, aunt). In the other, the two words were not typically related in their usage (e.g., wrist, corn). For pairs of both types, event‐related cortical potentials were recorded during and immediately after the presentation of the second word. The obtained waveforms differentiated these two types of pairs. For the unrelated pairs, the waveforms were significantly more negative about 400 ms after the second word was presented, thus replicating the “N400” phenomenon of the cognitive neuroscience literature. In addition, there was a strong positive‐tending wave form difference post‐stimulus presentation (peaked at about 500 ms) that also differentiated the unrelated from related stimulus pairs. In Experiment 2, the procedures were extended to study arbitrary stimulus—stimulus relations established via matching‐to‐sample training. Participants were experimentally näive adults. Sample stimuli (Set A) were trigrams, and comparison stimuli (Sets B, C, D, E, and F) were nonrepresentative forms. Behavioral tests evaluated potentially emergent equivalence relations (i.e., BD, DF, CE, etc.). All participants exhibited classes consistent with the arbitrary matching training. They were also exposed also to an event‐related potential procedure like that used in Experiment 1. Some received the ERP procedure before equivalence tests and some after. Only those participants who received ERP procedures after equivalence tests exhibited robust N400 differentiation initially. The positivity observed in Experiment 1 was absent for all participants. These results support speculations that equivalence tests may provide contextual support for the formation of equivalence classes including those that emerge gradually during testing.  相似文献

To account for voter decision making in initiative elections, we integrate theory and research on public opinion, misinformation, and motivated reasoning. Heuristic and motivated reasoning literatures suggest that voters' preexisting values interact with political sophistication such that politically knowledgeable voters develop systematically distorted empirical beliefs relevant to the initiatives on their ballots. These beliefs, in turn, can predict voting preferences even after controlling for underlying values, regardless of one's political sophistication. These hypotheses were tested using a 2003 voter survey conducted prior to a statewide initiative election that repealed a workplace safety regulation. Results showed that only those voters knowledgeable of key endorsements had initiative-specific beliefs that lined up with their underlying antiregulation values. Also, voters' empirical beliefs had an effect on initiative support even after controlling for prior values, and political sophistication did not moderate this effect.  相似文献

Theories of depression suggest that cognitive and environmental factors may explain the relationship between personality and depression. This study tested such a model in early adolescence, incorporating neuroticism, stress-generation and negative automatic thoughts in the development of depressive symptoms. Participants (896 girls, mean age 12.3 years) completed measures of personality and depressive symptoms, and 12 months later completed measures of depressive symptoms, recent stressors and negative automatic thoughts. Path analysis supported a model in which neuroticism serves as a distal vulnerability for depression, conferring a risk of experiencing dependent negative events and negative automatic thoughts, which fully mediate the effect of neuroticism on later depression. A second path supported a maintenance model for depression in adolescence, with initial levels of depression predicting dependent negative events, negative automatic thoughts and subsequent depressive symptoms. Unexpectedly, initial depression was also associated with later independent life events. This study establishes potential mechanisms through which personality contributes to the development of depression in adolescent girls.  相似文献

The purpose of this paper is to show that the standard notion of informed choice is unacceptable and must be replaced. To do so, I examine Foucault's analysis of people in contemporary society, drawing attention to the ways power relations act upon us, and to the possibility of resistance. I show how feminist moral theory can be enriched by Foucault's analysis. Applying this new understanding of people and moral theory to an analysis of informed choice, I claim that the standard notion of informed choice is unacceptable, in part because it relies on a false conception of people. Its “necessary” features—intention, understanding, and absence of controlling influences—are much more difficult, if not impossible, to obtain than proponents of the standard notion believe. I end by offering direction for creating a new, Foucault-inspired, feminist theory of informed choice.  相似文献

A public opinion survey was administered by telephone to nationally representative samples in the US and Germany to assess prevalence of homelessness as well as attitudes, opinions and knowledge regarding homelessness. Lower prevalence rates were found in Germany as compared with the US. German respondents demonstrated higher levels of general compassion, greater support for the public rights of the homeless, a greater tendency to view the homeless as trustworthy, and were more likely to view economic factors and less likely to view personal failings as integral to the problem of homelessness. Respondent age, gender, and political affiliation predicted many public opinion variables. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

Legal support for advocacy on behalf of gay male, lesbian, and bisexual male and female students was determined in a May 1999 Supreme Court ruling. This ruling, coupled with recent interpretations of the Title IX statute, strengthens the position for a more humanistic school environment. Recommendations for school counselors are included in this article. Apoyo legal para la abogacía en nombre de estudiantes homosexuales, lesbianas y bisexuales se determino en una decisión de la Corte Suprema de los Estados Unidos en Mayo de 1999. Esta decisión, en conjunto con interpretaciones recientes del estatuto “Title IX,” intensifica la postura que pide un ambiente más humanístico en las escuelas. Recomendaciones para consejeros escolares se incluyen en este artículo.  相似文献

This study is a survey of recreational users ( n = 85) of a scenic reservoir that was at the center of a controversy about whether the use of motorboats should be restricted or banned. We examined the hypothesis that the amount of goal interference that respondents experienced in the pursuit of recreational activities would be related to perceptions of consensus for their activities and for the regulations they preferred. We also hypothesized that perceived consensus would be related to greater preference for majority rule and less preference for compromise as the preferred strategy for resolving the conflict. Results show that goal interference was related to perceived consensus and that greater perceived consensus was related to unwillingness to compromise and preference for majority rule. Discussion centered on how perceptions about consensus arise from different experiences and on the role of perceived consensus in conflict resolution.  相似文献

The aim of the present study was to investigate the influence of maternal modeling on the acquisition of fear and avoidance towards fear-relevant and fear-irrelevant, novel stimuli in a sample of 71 toddlers. Children were shown a rubber snake or spider (fear-relevant objects) and a rubber mushroom or flower (fear-irrelevant objects), which were alternately paired with either negative or positive expression by their mothers. Both stimuli were presented again after a 1- and a 10-min delay, while mothers maintained a neutral expression. The toddlers showed increased fear and avoidance of the objects following negative reaction from their mothers than following positive maternal expression. This was similarly true for both fear-relevant and fear-irrelevant stimuli. In addition, no association was found between child temperament and behavioral responses and a weak association emerged between child temperament and emotional responses. The results demonstrate that young children can rapidly form conditioned emotional and behavioral responses via maternal reactions regardless of stimulus preparedness or child temperament. It is suggested that early maternal modeling may be relevant to a broad spectrum of fearful reactions.  相似文献

Little is known about the magnitude and duration of mood responses to daily negative events as a function of gender, history of mood disorder, and current substance use. Using computerized ambulatory monitoring techniques, perceived negativity of minor daily events and state affect were prospectively examined every 3 h on average for a 7-day period. Event negativity was associated with depressed mood for 6–9 h following event occurrence, and was associated with happy mood for 3–6 h. Gender and substance use moderated the relationship between event negativity and mood states concurrently, and remained influential for approximately 3 h following the event. History of mood disorder did not moderate any within- or across-day relationships between event negativity and mood. No evidence was found for mood uplifts following daily events in either within- or across-day analyses. The findings are discussed relative to assessment timing in investigations of vulnerability-stress theories.  相似文献

Religious involvement has been found to be associated with higher levels of commitment and relationship satisfaction among heterosexually married individuals (Mahoney et al., 1999). Little is known, however, about the religiosity of gay, lesbian, bisexual (GLB) individuals, and virtually nothing is known about religious involvement in same-sex couples. The purpose of this qualitative interview study was to examine couples' experiences of incorporating religious involvement into their committed relationships. In a sample of 14 same-sex couples, we found that couples used their spiritual/religious values to understand and undergird their relationships. In this process, they negotiated intra-couple differences in religious practices, involved themselves in activities that have religious or spiritual meaning to them, created religious social support for their relationships, and experienced some non-supportive or rejecting interpersonal interactions with religious family members, congregants, and strangers. These findings are instructive to therapists who work with same-sex couples and the family members of GLB individuals. We conclude with specific suggestions for practitioners.  相似文献
