Sex of human stimulus matters: female and male stimuli are processed differently in mental rotation tasks

ABSTRACT

The main goal of the present study was to assess whether the sex of a human stimulus affects mental rotation performance. The results are pretty straight-forward: Men show a better performance than women and also male stimuli result in a faster processing by both women and men compared to female stimuli. Furthermore, the advantage of egocentric transformations over object-based transformations disappeared for females in difficult tasks using female stimuli. This experiment gives a hint that women are affected to a greater extent from the sex of the presented stimuli compared to men. The underlying mechanisms need to be investigated in future research.     

Criticisms of the satiety hypothesis as an explanation for within-session decreases in responding

The authors of four papers recently reported that satiation provides a better explanation than habituation for within-session decreases in conditioned responding. Several arguments question this conclusion. First, the contribution of habituation to within-session changes in responding seems clearly established. Information that is consistent with habituation, but that is difficult to reconcile with satiation, is not adequately addressed. Second, the limited evidence offered in support of satiation is ambiguous because the results are just as compatible with habituation as with other satiety variables. Finally, the term satiation is used in an intuitive way that is sometimes contradicted by research about the termination of ingestion. Use of the technical term satiation in a way that differs from its conventional usage will only isolate operant psychology from other areas of psychological research.     

Misconduct in science and the german law

In the past, only norms and rules developed for other types of illegal activities could be applied to misconduct in science in Germany. But only particularly blatant cases of misconduct can be dealt with efficiently in this way. Nowadays, a couple of very important funding agencies and research institutions have enacted special procedures that apply in cases of suspected scientific misconduct. A strongly decentralised system of dealing with misconduct in science is being established in Germany. An earlier version of this paper was presented at a symposium, Scientific Misconduct. An International Perspective, organised by The Medical University of Warsaw, 16 November, 1998.     

Spiritual Beliefs and Barriers Among Managed Care Practitioners

Purpose: Ninety percent of American adults believe in God and 82% pray weekly. A majority wants their physicians to address spirituality during their health care visit. However, clinicians incorporate spiritual discussion in less than 20% of visits. Our objectives were to measure clinician beliefs and identify perceived barriers to integrating spirituality into patient care in a statewide, primary care, managed care group. Methods: Practitioners completed a 30-item survey including demographics and religious involvement (DUREL), spirituality in patient care (SPC), and barriers (BAR). We analyzed data using frequencies, means, standard deviations, and ANOVA. Findings: Clinicians had a range of religious denominations (67% Christian, 14% Jewish, 11% Muslim, Hindu or Buddhist, 8% agnostic), were 57% female and 24% had training in spirituality. Sixty-six percent reported experiencing the divine. Ninety-five percent felt that a patients spiritual outlook was important to handling health difficulties and 68% percent agreed that addressing spirituality was part of the physicians role. Ninety-five percent of our managed care group noted 8lack of time as an important barrier, lack of training was indicated by 69%, and 21% cited fear of response from administration. Conclusions: Managed care practitioners in a time constrained setting were spiritual themselves and believed this to be important to patients. Respondents indicated barriers of time and training to implementing these beliefs. Comparing responses from our group to those in other published surveys on clinician spirituality, we find similar concerns. Clinician education may overcome these barriers and improve ability to more fully meet their patients expressed needs regarding spirituality and beliefs.*This material has previously been presented as an abstract at the Culture and End of Life Conference, Association of Medical Colleges Spirituality, Kansas City, MO, September 12–14, 2002.Project supported by the Foundation for Spirituality in Medicine, Baltimore, MD     

Sex differences in a human analogue of the Radial Arm Maze: the "17-Box Maze Test"

This study investigated sex differences in spatial memory using a human analogue of the Radial Arm Maze: a revision on the Nine Box Maze originally developed by called the 17-Box Maze Test herein. The task encourages allocentric spatial processing, dissociates object from spatial memory, and incorporates a within-participants design to provide measures of location and object, working and reference memory. Healthy adult males and females (26 per group) were administered the 17-Box Maze Test, as well as mental rotation and a verbal IQ test. Females made significantly fewer errors on this task than males. However, post hoc analysis revealed that the significant sex difference was specific to object, rather than location, memory measures. These were medium to large effect sizes. The findings raise the issue of task- and component-specific sexual dimorphism in cognitive mapping.     

Parent and Child Anxiety Sensitivity: Relationship in a Nonclinical Sample

Little is known about the relationship between parent and child anxiety sensitivity (AS), particularly in nonclinical samples. The present study examined this association in 207 healthy parent-child pairs including 244 children (mean age = 12.3 years, 103 girls) and 226 parent figures (175 mothers). Sequential multiple linear regression revealed that parent AS was significantly associated with child AS in girls, but not in boys. Parent AS accounted for 9% of incremental variance in child AS, after controlling for child age, parent depression, and parent anxiety. Analyses of parent AS dimensions indicated that the social concerns dimension accounted for 14% of incremental variance in child AS in girls only. Parent anxiety and depression showed no association with child AS, once parent AS was taken into account. The findings indicate that parent AS, especially AS social concerns, demonstrates a significant relationship with child AS in this nonclinical sample of girls.     

Adolescent Girls’ and Boys’ Science Peer Relationships and Perceptions of the Possible Self as Scientist

Girls tend to have less peer support for their science interests than do boys, which may contribute to gender differences in science motivation. The effect of science peer relationships on adolescents visions of their possible personal future lives as scientists was studied in 161 female and 163 male gifted high school students who participated in summer science enrichment programs. Student reports of having positive science peer relationships were associated with more positive expectations of the possible personal self as scientist prior to the programs, and both program-related and nonprogram-related science peer relationships were associated with changes in the possible self at posttesting and at 6 month follow-up. These relations held for both male and female students. At follow-up, girls reported a stronger social niche with fellow program participants and stronger science peer relationships than did boys. Implications of the findings are discussed within the larger gendered societal context for science achievement.     

Parental Preference for Sex of Newborn as Reflected in Positive Affect in Birth Announcements

Content analysis of birth announcements was used as a method to investigate parental preference for the sex of newborns in Canada. The expression of positive affect (happiness and pride) in birth announcements was examined to determine whether parents express these emotions differently as a function of the sex of newborn. The findings suggest that parents express relatively more pride at the birth of boys than girls, whereas the opposite results were found for happiness. Parents seem unconsciously to categorize boys and girls into two distinct motivational systems: status and attachment, which are related to pride and happiness, respectively. This distinction may influence parents perception of their childs worth and their subsequent investment in their childs development.     

礼与食孰重:儒墨之辩新论

孔墨“俱道尧舜”但政治理想却截然不同,其主要原因在于两方面,首先是他们有着各不相同的历史传统和政治理想,其次是他们对于中国轴心时代的社会现实有着完全不同的认识和评价。两家显学的根本分歧在于“礼与食孰重”,儒家认为生活资料的匮乏是由于人的动物性欲望未能得到有效的遏制,因而特别强调了一整套礼仪制度对于文明的重要性。墨家则认为正是由于礼仪制度本身的维系严重消耗了社会的物质基础,才使得人们为了满足饥饿的食本能而不得不弱肉强食。这个思想史的问题至今仍未结束。
