Bringing together self‐determination theory, intergroup theories based on the social identity approach, and normative approaches, three studies conducted among hockey fans tested if social norms and social identity predict greater self‐determined motivation to engage in derogatory behaviours against an outgroup team and higher frequency of these behaviours. Higher self‐determination was conceptualised as an indicator of internalisation. In Study 1, hockey fans who identified more strongly as fans of the Montreal Canadiens (N = 181) displayed a stronger positive association between the perceived norm in favour of outgroup derogation and self‐determined motivation to engage in derogatory behaviours against fans of an outgroup team. This interaction also emerged on the frequency with which the derogatory behaviours were enacted. In Studies 2 and 3 (Ns = 105 and 116), this norm by social identity interaction was replicated on both the self‐determination and the frequency outcomes for fans of a diversity of teams in the National Hockey League. In Study 3, these findings were observed over and above a manipulation that framed derogatory behaviours as being either harmful or beneficial. Results are discussed in light of motivational theories, normative approaches, and intergroup theories based on the social identity approach. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Research on early signs of autism in social interactions often focuses on infants’ motor behaviors; few studies have focused on speech characteristics. This study examines infant‐directed speech of mothers of infants later diagnosed with autism (LDA; n = 12) or of typically developing infants (TD; n = 11) as well as infants’ productions (13 LDA, 13 TD). Since LDA infants appear to behave differently in the first months of life, it can affect the functioning of dyadic interactions, especially the first vocal productions, sensitive to expressiveness and emotions sharing. We assumed that in the first 6 months of life, prosodic characteristics (mean duration, mean pitch, and intonative contour types) will be different in dyads with autism. We extracted infants’ and mothers’ vocal productions from family home movies and analyzed the mean duration and pitch as well as the pitch contours in interactive episodes. Results show that mothers of LDA infants use relatively shorter productions as compared to mothers talking to TD infants. LDA infants’ productions are not different in duration or pitch, but they use less complex modulated productions (i.e., those with more than two melodic modulations) than do TD. Further studies should focus on developmental profiles in the first year, analyzing prosody monthly.  相似文献

Three experiments examined the factors that are responsible for producing a high rate of autoshaped keypecking in pigeons when the conditioned stimulus is followed by varying consequences. In the first experiment, a single group received three serial conditioning schedules presented on different keys. The AB+ schedule consisted of trials in which A was followed by B, which, in turn, was followed by food. The CD+C° schedule consisted of reinforced CD pairings plus presentations of C alone. The EF+/0 schedule consisted of a mixture of reinforced and nonreinforced EF pairings. It was found that responding was most rapid during C, slowest during E, and at an intermediate rate during A. In spite of this ordering A was chosen in preference to C, when these stimuli were presented simultaneously. In Experiments 2 and 3 the schedules AB+A° and AB+/0 were presented to separate groups. The rate of responding during A was substantially greater in the former schedule, yet it was found that this stimulus was equally ineffective as a conditioned reinforcer in both groups. We propose that autoshaped keypecking is composed of two types of response, a conditioned response and an orienting response, which are governed by different processes.  相似文献

The current review summarizes the literature on competing stimulus assessments (CSAs). CSAs are pretreatment assessments designed to systematically identify stimuli that reduce problem behavior (PB), ostensibly through reinforcer competition or substitution. We report on the participant characteristics, outcomes, and predictive validity of published CSAs that included (a) no-stimulus control trial(s), (b) test trials during which each stimulus was available singly and noncontingently, and (c) measurement of PB and stimulus engagement or contact. Results showed that CSAs have broad utility across a variety of topographies and functions of PB. In the majority of CSA applications for which extended analyses, or validations, were performed, stimuli shown to reduce PB during the CSA produced similar reductions during extended analysis. This was the case regardless of topography or function of PB, or whether the stimuli were assumed to be “matched” to the stimulation thought to be produced by PB. Implications for future research are discussed.  相似文献

We present data on well‐being and quality of life in the world, including material quality of life such as not going hungry, physical health quality of life such as longevity, social quality of life such as social support, environmental health such as clean water, equality in income and life satisfaction, and levels of subjective well‐being (SWB). There are large differences between nations in SWB, and these are predicted not only by economic development, but also by environmental health, equality and freedom in nations. Improving trends in SWB are seen in many countries, but declining SWB is evident in a few. Besides average differences in SWB between nations, there are also large disparities within many countries. We discuss the policy opportunities provided by national accounts of SWB, which are increasingly being adopted by many societies. They provide the opportunity to inform policy deliberations with well‐being information that reflects not only economic development, but also other facets of quality of life as well. National accounts of SWB reflect the quality of life in areas such as health, social relationships and the natural environment, and therefore capture a broader view of societal well‐being than afforded by measures of economic progress alone.  相似文献
