A frequent pattern of marital dysfunction seen in an academic setting is described. Typically, the wife of a professor sublimates her own strong intellectual achievement needs in order to facilitate her husband's success. After he achieves renown, she expects he will support her efforts to satisfy suppressed achievement strivings. The husband/professor is locked into an external reward system and is unwilling to meet his wife's needs, leading to marital conflict. Background factors in both spouses set up this dysfunctional pattern. Marital therapy with an emphasis on self versus others' expectations for achievement is recommended. A case study is presented. 相似文献
Although ‘anxiety’ has traditionally been hypothesized as the cognitive mediating CR which results from electrical a versive conditioning, alternate competing hypotheses have not been adequately studied. This investigation has generated four constructs from a factor analysis of adjective ratings on alcohol-related stimuli and four constructs from an identical analysis of ratings on non-alcohol related stimuli. As these constructs are orthogonal, each can be used as an independent measure of ‘cognitive mediator’ or alternative competing hypothesis. The alcohol-related constructs appeared to be: (1) dangerous vs. safety; (2) approach or appetitiveness: (3) avoidance or aversiveness; and (4) general evaluation good vs. bad. 相似文献
A software system (NOVA SKED) was developed for the experimental control and collection of data from operant behavior experiments that is compatible with the Data General Corporation real-time disk operating system (RDOS). NOVA SKED is based on the SKED state notation language originally implemented on Digital Equipment Corporation PDP-8 series of minicomputers. The system includes a compiler written in FORTRAN, a multitasking run-time system that can be configured to run up to 30 stations, a data back-up system, standard data manipulation programs and subroutines, and user manuals. 相似文献
Attention deficit/hyperactivity disorder (ADHD) is associated with friendship difficulties. This may partly account for the increasingly recognised association between ADHD and subsequent depression. Little is known about the types of friendship difficulties that could contribute to the association between ADHD and depressive symptoms and whether other relationships, such as parent–child relationships, can mitigate against potential adverse effects of friendship difficulties. In a representative UK school sample (n?=?1712), three main features of friendship (presence of friends, friendship quality and characteristics of the individual’s classroom friendship group) were assessed in a longitudinal study with two assessment waves (W1, W2) during the first year of secondary school (children aged 11-12 years). These friendship features (W1) were investigated as potential mediators of the prospective association between teacher-rated ADHD symptoms (W1) and self-rated depressive symptoms (W2) seven months later. Parent–child relationship quality (W1) was tested as a moderator of any indirect effects of ADHD on depression via friendship. ADHD symptoms were inversely associated with friendship presence, friendship quality and positive characteristics of classroom friendship groups. Depressive symptoms were inversely associated with presence and quality of friendships. Friendship quality had indirect effects in the association between ADHD and subsequent depressive symptoms. There was some evidence of moderated mediation, whereby indirect effects via friendship quality attenuated slightly as children reported warmer parent–child relationships. This highlights the importance of considering the quality of friendships and parent–child relationships in children with ADHD symptoms. Fostering good quality relationships may help disrupt the link between ADHD symptomology and subsequent depression risk.
Into the Light, a recently mounted collectively curated museum exhibition, exposed and countered histories and legacies of 20th‐century “race betterment” pedagogies taught in Ontario's postsecondary institutions that targeted some groups of people, including Anishinaabe, Black, and other racialized populations, and disabled and poor people, with dehumanizing ideas and practices. This article advances understandings of the transformative potential of centralizing marginalized stories in accessible and creative ways to disrupt, counter, and draw critical attention to the brutal impacts of oppressive knowledge. The “counter‐exhibition” prioritized stories of groups unevenly targeted by such oppression to contest and defy singular narratives circulating in institutional knowledge systems of what it means to be human. The authors draw on feminist, decolonial and disability scholarship to analyze the exhibition's curation for the ways it collectively and creatively: (1) brought the past to the present through materializing history and memory in ways that challenged archival silences; and (2) engaged community collaboration using accessible, multisensory, multimedia storytelling to “speak the hard truths of colonialism” (Lonetree) while constructing a new methodology for curating disability and access (Cachia). The authors show how the exhibition used several elements, including counter‐stories, to end legacies of colonial eugenic violence and to proliferate accounts that build solidarity across differences implicated in and impacted by uneven power (Gaztambide‐Fernández). 相似文献
Previous work from our laboratory has demonstrated that rats display a preference for directional responding over true place navigation in the Morris water task. The present study evaluated the range of situations in which this preference is observed and attempted to identify methods that favor navigation to the precise location of the escape platform in the room. A preference for directional responding over place navigation was observed in a wide range of procedures that included providing extensive training (Experiment 1), providing only platform placement experience in the absence of active swim training (Experiment 2), training navigation to multiple platform locations in a moving platform variant of the task (Experiment 3), and explicitly training navigation to a precise location in the room, versus navigation in a particular direction, regardless of the pool's position in the room (Experiments 4-5). A modest preference for navigation to the precise spatial location of the platform was observed when the pool wall was virtually eliminated as a source of control by filling it to the top with water (Experiment 6). 相似文献
15 male and 13 female soldiers participated in a study to examine the effects of sex, rifle stock length 117.8 cm, 22.3 cm, and 26.2 cm), and rifle weight (3.2 kg vs 3.8 kg) on military marksmanship performance. The Noptel simulator was used to assess marksmanship accuracy (proximity of shots to the target center) and precision (proximity of shots to one another regardless of proximity to the target center). There were no significant differences in either measure of marksmanship performance as a function of sex. Marksmanship accuracy was significantly better with the shortest rifle stock, and marksmanship precision was significantly better with the lighter rifle. Regardless of the sex of the shooter, stock length and weapon weight should be considered in any new combat rifle design as these results indicate they significantly affect marksmanship. 相似文献
