An experiment was conducted to observe the influence of autonomic arousal on subsequent gambling behavior. Thirty-seven male
and 32 female regular Electronic Gaming Machine (EGM) players were recruited through newspaper advertisements. Participants
were randomly assigned to either: (1) a control condition, or (2) an experimental condition that introduced a loud white-noise
event (80 db) at fixed 120 s intervals throughout the 5-min EGM gambling session. Galvanic Skin Response (GSR) measurements
showed that the manipulation was successful in elevating autonomic arousal. The results showed differences in behavioral response
to the manipulation based on prior experience with gambling problems. Persons with many gambling problems had lower average
bet-sizes in the white-noise condition compared to the control, while those with few or no problems had higher average bet-sizes.
The results suggest that arousal may provide different signals to gamblers with few versus many problems. Gamblers with many
problems may interpret their arousal as a sign that they will soon lose money, while gamblers with few or no problems may
associate feelings of arousal exclusively with winning. 相似文献

Research and theory regarding the social facilitation effect generates the expectation that the presence of other gamblers (or co-actors) in a gaming venue is likely to intensify individual gambling behavior and magnify losses. Fifty male and 66 female participants (116 total) played a computer-simulated electronic gaming machine with a fixed winning sequence, followed by an indefinite losing sequence. Measures of the intensity of gambling behavior included the final payout (a direct measure of losses), average bet-size, number of trials played, and the speed of play. Some participants received false feedback from the computer designed to suggest that other gamers in adjacent rooms were playing and sometimes winning at the same game. Persons who received both sight and sound information, including winning bells and instant messages regarding the wins of other (fake) players, placed more bets and lost more money compared to the other conditions with less information. 相似文献

The Four Es is a 40-item scale measuring psychological risk for the development of problem gambling behavior. One-year follow-up interviews
(n = 395) from a previously reported phone survey in Queensland, Australia (n = 2,577) (Rockloff & Dyer, 2006) tested the ability of the Four Es instrument to prospectively identify persons who would later develop gambling problems.
Two groups of participants were selected for the 1-year follow-up interviews, including (1) persons who had gambling problems,
high-risk alcohol abuse problems, and/or substance abuse problems (abuse group); and (2) a random selection of other persons
from the original survey (random group). The results indicated that the “Excess” trait, which measures impulsive behavior,
was predictive of relative increases in gambling problems for both groups over the 1-year period. Additionally, the Four Es
questionnaire showed good psychometric properties in the surveys, with a test-retest reliability of r = .70 and a Cronbach’s alpha reliability of α = .90 and .92 in the original and follow-up interviews, respectively. 相似文献

This article presents an evaluation framework developed to assess the first-level effects of introducing the Standard Days Method (SDM) in Peru Ministry of Health clinics. Four questions are asked: 1) To what extent do providers routinely achieve SDM service delivery standards? 2) Is the time invested in SDM delivery consistent with program norms? 3) How does SDM delivery compare with delivery of established methods? and 4) How does SDM introduction affect delivery of established methods? A study at 62 clinics demonstrated the framework's usefulness. The Standard Days Method introduction had positive overall effects on the quality of care but provider training needed adjustments. 相似文献

Few studies have examined the influence of environmental factors on children's executive functioning (EF) performance. The present study examined the effects of a punitive vs. non‐punitive school environment on West African children's EF skills. Tasks included a ‘cool’ (relatively non‐affective) and ‘hot’ (relatively affective/motivational) version of three EF tasks: delay of gratification; gift delay; and dimensional change card sort. Children had more difficulties with the hot versions of the tasks than the cool versions, and older children outperformed younger children. After controlling for verbal ability (Peabody picture vocabulary test‐third edition), a consistent pattern of interaction between school and grade level emerged. Overall, kindergarten children in the punitive school performed no differently than their counterparts in the non‐punitive school. However, in grade 1, children in the punitive school performed significantly worse than their counterparts in the non‐punitive school. These results point to the need to consider interactions among discipline style, age, and internalization processes of self‐regulation to better understand environmental influences on EF development. 相似文献

The economic recession, the dynamism and complexity of the markets and the generalised globalisation of the world economy have forced many companies to rethink and reorganise their industrial strategies. Through identifying and taking advantage of the key technologies of a company, this work presents a new and original methodology for dealing with a general technological diversification process. The methodology, which includes an innovative cognitive perspective and its corresponding decisional tool (decision support system) has been used to select the best product in a process of technological diversification that, along with the key technologies, identifies the sub-levels consonant to the sub-technologies and applications to sectors and products. The multicriteria selection tool employed in the proposed methodology, based on the analytic hierarchy process, allows the integration of multiple scenarios, actors and criteria, both tangible and intangible. The methodology has been applied to a case study in the Spanish automotive auxiliary sector. 相似文献

This paper critically reviews recent research exploring risk and protective factors for the development of problematic substance use in populations of young people. Specific populations of young people who are most vulnerable to developing problematic patterns of use are identified, and alterations to methods of data collection which would improve the ability of local authorities to monitor these populations and more efficiently target them for early preventative interventions are highlighted. It is argued that social‐psychological research techniques and approaches should be used to complement a risk and protection‐focused approach in order to improve the design and evaluation of interventions, and provide decision‐aids for practitioners when assessing the needs of vulnerable young people. Examples are provided to demonstrate the utility of social psychology in this regard, and the paper concludes with specific recommendations for future research and services.

We used data from the Birth to Twenty Cohort study to understand children’s receipt of financial support from their fathers in a low income, Black community in urban South Africa. Specifically, we (1) described fathers’ financial support over the life course of children; (2) estimated survival probabilities of receiving support for all children and not receiving support for children who experienced a parental union dissolution; and (3) identified factors that explained variation in the receipt of support after a union dissolution. Results suggest that most children received full or partial support throughout the life course. Furthermore, a high proportion of children received support after a union dissolution with much of the variation driven by pre-dissolution support, father’s education and the presence of extended kin. 相似文献

This paper examines the effect of country-specific institutional constructs on the relationship between ownership concentration
and performance for firms in the eight Continental European countries of Austria, Belgium, Germany, Spain, France, Italy,
the Netherlands and Portugal. Using data from publicly-traded firms owned by other companies (i.e., blocks), measures of the
quality of investor and creditor protection and the effectiveness of legal institutions are applied. Employing a hierarchical
moderated multiple regression analysis, differential validity is established for the relationship between ownership concentration
and performance as measured by return on shareholders’ funds. This differential effect comes from creditor protection regimes
and is consistent with a relational corporate governance model based on debt finance and concentrated ownership. 相似文献
