Participants were pretrained and tested on mutually entailed trigonometric relations and combinatorially entailed relations as they pertained to positive and negative forms of sine, cosine, secant, and cosecant. Experiment 1 focused on training and testing transformations of these mathematical functions in terms of amplitude and frequency followed by tests of novel relations. Experiment 2 addressed training in accordance with frames of coordination (same as) and frames of opposition (reciprocal of) followed by more tests of novel relations. All assessments of derived and novel formula‐to‐graph relations, including reciprocal functions with diversified amplitude and frequency transformations, indicated that all 4 participants demonstrated substantial improvement in their ability to identify increasingly complex trigonometric formula‐to‐graph relations pertaining to same as and reciprocal of to establish mathematically complex repertoires. 相似文献

In Experiment 1, more and less relations were trained for arbitrary Stimuli A1 and A2 with 3 children with autism. The following conditional discriminations were then trained: A1‐B1, A2‐B2, B1‐C1, B2‐C2. In subsequent tests, participants showed derived more‐less mands (mand with C1 for more and mand with C2 for less). A training procedure reversed the B‐C conditional discriminations, and participants then showed derived reversed more—less mands (mand with C1 for less, C2 for more). Baseline B‐C relations were retrained, and participants subsequently demonstrated a return to the original derived manding. A second experiment with 1 prior participant and 1 naive participant removed a possible confounding effect. Establishing derived manding may be an advantageous component when teaching a mand repertoire in applied settings. 相似文献

This study was designed to examine whether self‐esteem can be used as a source of evaluative conditioning, and whether implicit or explicit self‐esteem was more predictive of the evaluative conditioning effect. Moreover, the role of contingency awareness in the acquisition of the evaluative conditioning effect was also examined. Words related to the self and a general other were served as unconditioned stimuli (USs) in the evaluative conditioning process in order to see whether the evaluation could be transferred to neutral, abstract paintings after 10 times of pairing. An evaluative conditioning effect was demonstrated in that the evaluation of the paintings became more positive after repeatedly paired with words about the self but not words about general others. Implicit self‐esteem predicted the magnitude of the evaluative conditioning effect, while the association between explicit self‐esteem and the evaluative conditioning effect was nonsignificant, both with and without the effect of contingency awareness being controlled for.

This fMRI study examined the neural correlates of the observed improvement in advantageous risk-taking behavior, as measured by the number of adjusted pumps in the Balloon Analogue Risk Task (BART), following a 60-day course of a Traditional Chinese Medicine (TCM) recipe, specifically designed to regulate impulsiveness in order to modulate risk-taking behavior. The 14 participants recruited for this study were randomly assigned to the experimental and control groups and the TCM recipe (Panax, 520 mg; Astragalus membranaceous Bunge, 520 mg; Masnetitum, 840 mg; Ostrea gigas Thumb, 470 mg; Thinleaf Milkwort Root Radix Polygalae, 450 mg; and Os Draconis, 470 mg) was administered, as a diet supplement, to the seven participants in the experimental group. The neural activity of the two groups was monitored by a 3T MRI scanner, before and after the 60-day treatment. Associated with the improved advantageous risk-taking behavior seen in the experimental group, significantly stronger blood oxygenation level dependent (BOLD) responses were observed in the bilateral dorsolateral prefrontal cortex (DLPFC), left putamen, left thalamus, right insula, and right anterior cingulate cortex (ACC), regions which have previously been reported as being involved in risk-taking decision making. The effect of the TCM in improving advantageous risk-taking decision making appears to have been related to the enhanced efficiency of the cognitive affective system, the PFC–ACC–insula–striatum network, which functions to inhibit impulsiveness, to sensitize reward-related information, and to allow the opportunity, during risk estimation, to evaluate potential gains and losses. The findings of this study suggest that interventions acting on factors modulating risk-taking decision making could have a beneficial effect in terms of optimizing risk-taking behavior. 相似文献

Cameroonian university students (N = 666) assessed whether certain different societal positions that the law grants to women and men (the husband chooses the marital home, the husband wields parental power, a married woman cannot freely engage in trade, the husband administers his wife's personal property) and certain cultural practices (female genital mutilation, parents arranging their children's marriage) were seen as violations of women's human rights. Justifications for the choices were also analysed. Female genital mutilation was most often seen as a violation of women's human rights, and the husband selecting the marital home was least often seen as a violation. These differences were explained by cultural specificities. Women more often than men saw the cases as violations of rights. Respondents coming from the North saw the cases less often as violations of rights than respondents from other geocultural areas, which was in accordance with their previously observed higher collectivism.

The ‘NIMBY’ (Not In My Back Yard) concept is commonly used to explain public opposition to new developments near homes and communities, particularly arising from energy technologies such as wind farms or electricity pylons. Despite its common use, the concept has been extensively critiqued by social scientists as a useful concept for research and practice. Given European policy goals to increase sustainable energy supply by 2020, deepening understanding of local opposition is of both conceptual and practical importance. This paper reviews NIMBY literature and proposes an alternative framework to explain local opposition, drawing upon social and environmental psychological theory on place. Local opposition is conceived as a form of place‐protective action, which arises when new developments disrupt pre‐existing emotional attachments and threaten place‐related identity processes. Adopting a social constructivist perspective and drawing on social representation theory, a framework of place change is proposed encompassing stages of becoming aware, interpreting, evaluating, coping and acting, with each stage conceived at multiple levels of analysis, from intrapersonal to socio‐cultural. Directions for future research and potential implications of the place‐based approach for public engagement by energy policy‐makers and practitioners are discussed.

Although past research has associated loneliness with negative perceptions of others, P. Christensen and D. A. Kashy (1998), using the social relations model (SRM), found that among new acquaintances, loneliness was associated with more positive other‐perceptions. SRM was used to examine loneliness and interpersonal perception within existing social networks. Seventy‐three university students in the United States rated themselves and others on 19 attributes and also judged how they thought others saw them (meta‐perceptions). Results indicated that lonely people tended to be more negative toward closer targets and somewhat positive toward less close acquaintances. Lonely people had lower self‐regard and perceived self‐regard, invariant across acquaintanceship, and were rated more negatively by others. Relationship contexts thus moderate effects of loneliness on other‐perceptions. 相似文献

Children's suggestibility is typically measured using a three‐stage ‘event–misinformation–test’ procedure. We examined whether suggestibility is influenced by the time delays imposed between these stages, and in particular whether the temporal discriminability of sources (event and misinformation) predicts performance. In a novel approach, the degree of source discriminability was calculated as the relative magnitude of two intervals (the ratio of event–misinformation and misinformation–test intervals), based on an adaptation of existing ‘ratio‐rule’ accounts of memory. Five‐year‐olds (n =150) watched an event, and were exposed to misinformation, before memory for source was tested. The absolute event–test delay (12 versus 24 days) and the ‘ratio’ of event–misinformation/misinformation–test intervals (11:1, 3:1, 1:1, 1:3 and 1:11) were manipulated across participants. The temporal discriminability of sources, measured by the ratio, was indeed a strong predictor of suggestibility. Most importantly, if the ratio was constant (e.g. 18/6 versus 9/3 days), performance was remarkably similar despite variations in absolute delay (e.g. 24 versus 12 days). This intriguing finding not only extends the ratio‐rule of distinctiveness to misinformation paradigms, but also serves to illustrate a new empirical means of differentiating between explanations of suggestibility based on interference between sources and disintegration of source information over time. 相似文献
