Truly flower-naïve bumblebees, with no prior rewarded experience for visits on any visual patterns outside the colony, were tested for their choice of bilaterally symmetric over asymmetric patterns in a radial-arm maze. No preference for symmetry was found. Prior training with rewarded black and white disks did, however, lead to a significant preference for symmetry. The preference was not specific to symmetry along the vertical axis: a preference for horizontal symmetry was found as well. The results challenge the notion that a preference for bilateral symmetry is unlearned. The preference for symmetry was the product of non-differential conditioning. 相似文献

The authors examined which variables predicted the likelihood of counseling students' decision to pursue a gerocounseling specialization by using logistic regression analysis. Results found that overall interest, perceived preparation, training willingness, and importance were predictive factors. Curriculum strategies on how to implement these variables into existing counselor education course work are discussed. 相似文献

This study examined the influence of gender, socioeconomic status, and race/ethnicity on the career aspirations of over 22,000 8th and 10th grade youth. The top five occupations identified by youth as aspirations included artist, lawyer, musician, FBI agent, and actor/actress. Top occupations were also reported for each gender × socioeconomic status × race/ethnicity group. Aspirations were coded by social prestige level, minimum education requirements, and median salary. Results revealed significant main effects for socioeconomic status and race/ethnicity as well as significant interaction effects. Further, significant gender main effects and a significant gender × ethnicity interaction were found for occupational prestige and educational requirements. 相似文献

We tested the assumption that the act of inhibiting ongoing behavior requires physiological work. In a guilty knowledge test (GKT) paradigm, subjects were induced to attempt to deceive the experimenter on two separate occasions while electrodermal activity was measured. For 20 of the 30 subjects, overt behaviors (changes in eye movement and facial expression) were recorded during the second GKT. Results indicated that the incidence of behaviors decreased during their deceptive responses. This behavioral inhibition coincided with increases in skin conductance level. In addition to suggesting nonverbal correlates of deception, the results indicate that long-term behavioral inhibition may be a factor in psychosomatic disease. 相似文献

It has been reported in Western research on intimate partner violence (IPV) that there are similar rates between males and females (Filbert, 2010). The objective of this study was to compare male and female prisoners from Singapore on rates of IPV as well as the Johnson (2006) types of IPV. Women (n = 75) self-reported higher rates of physical IPV perpetration in the past year (64.0%) than (n = 75) did men (46.1%). Women reported similar rates of IPV for themselves and their partners in the past year (64.0%), while men reported slightly more physical IPV for themselves (46.1%) than they did for their female partners (41.3%). In line with Johnson (2006), rates of intimate terrorism were calculated between 5% and 7% for themselves and their partners, with little variation due to gender. Violent resistance (VR) was calculated at between 2.1% and 7%, with more female than male VR reported for women. Much higher rates of situational couple violence was calculated for both males and females, ranging from 53.3% to 66.7% in the past year, while mutual violent control was significantly lower, ranging from between 14.8% to 20.0%, with data being discussed in relation to patriarchal and family violence perspectives. We concluded that the rates of IPV between males and females were very similar as were the types of IPV. Further research with other cultures should be encouraged for comparison with Western samples. 相似文献

Emotional tears tend to increase perceived sadness in facial expressions. However, it is unclear whether tears would still be seen as an indicator of sadness when a tearful face is observed in an emotional context (e.g., a touching moment during a wedding ceremony). We examine the influence of context on the sadness enhancement effect of tears in three studies. In Study 1, participants evaluated tearful or tearless expressions presented without body postures, with emotionally neutral postures, or with emotionally congruent postures (i.e., postures indicating the same emotion as the face). The results show that the presence of tears increases the perceived sadness of faces regardless of context. Similar results are found in Studies 2 and 3, which used visual scenes and written scenarios as contexts, respectively. Our findings demonstrate that tears on faces reliably indicate sadness, even in the presence of contextual information that suggests non-sadness emotions. 相似文献

This study addresses a possible link between suicide and casino gambling. Resident suicide rates are analyzed for (a) a 1990 cross-section of 148 U.S. metropolitan areas and (b) before and after the advent of legalized casinos in five U.S. counties. Data are drawn from government and gaming industry sources. In cross-section, metro area suicide is strongly correlated with region, accidental death and homicide rates, age and race composition, and economic vitality, followed by a modest net positive correlation with casino presence. By contrast, the time series analysis yields no evidence of a gambling effect. 相似文献
