Sexual infidelity can be costly to members of both the extra-pair and the paired couple. Thus, detecting infidelity risk is potentially adaptive if it aids in avoiding cuckoldry or loss of parental and relationship investment. Among men, testosterone is inversely related to voice pitch, relationship and offspring investment, and is positively related to the pursuit of short-term relationships, including extra-pair sex. Among women, estrogen is positively related to voice pitch, attractiveness, and the likelihood of extra-pair involvement. Although prior work has demonstrated a positive relationship between men?s testosterone levels and infidelity, this study is the first to investigate attributions of infidelity as a function of sexual dimorphism in male and female voices. We found that men attributed high infidelity risk to feminized women?s voices, but not significantly more often than did women. Women attributed high infidelity risk to masculinized men?s voices at significantly higher rates than did men. These data suggest that voice pitch is used as an indicator of sexual strategy in addition to underlying mate value. The aforementioned attributions may be adaptive if they prevent cuckoldry and/or loss of parental and relationship investment via avoidance of partners who may be more likely to be unfaithful. 相似文献

The Eastern Synod of the Evangelical Lutheran Church in Canada (ELCIC) sponsors the Crossing the Boundaries (CTB) workshop,
a program that focuses on the maintenance of appropriate boundaries in clergy-congregant relationships as a means to prevent
clergy sexual misconduct. Drawing primarily on an analysis of the synod-sanctioned workshop materials, an observation of the
workshop, and interviews with 10 pastors who have attended the workshop, this paper explores differing conceptions of power
and gender held by the synod officials and workshop participants. 相似文献

Eye-blink conditioning is associated with changes in synaptic ultrastructure in the rabbit interpositus nuclei 下载免费PDF全文

Eye-blink conditioning involves the pairing of a conditioned stimulus (usually a tone) to an unconditioned stimulus (air puff), and it is well established that an intact cerebellum and interpositus nucleus, in particular, are required for this form of classical conditioning. Changes in synaptic number or structure have long been proposed as a mechanism that may underlie learning and memory, but localizing these changes has been difficult. Thus, the current experiment took advantage of the large amount of research conducted on the neural circuitry that supports eye-blink conditioning by examining synaptic changes in the rabbit interpositus nucleus. Synaptic quantifications included total number of synapses per neuron, numbers of excitatory versus inhibitory synapses, synaptic curvature, synaptic perforations, and the maximum length of the synapses. No overall changes in synaptic number, shape, or perforations were observed. There was, however, a significant increase in the length of excitatory synapses in the conditioned animals. This increase in synaptic length was particularly evident in the concave-shaped synapses. These results, together with previous findings, begin to describe a sequence of synaptic change in the interpositus nuclei following eye-blink conditioning that would appear to begin with structural change and end with an increase in synaptic number. 相似文献

What are creative people like? Openness to experience is important to creativity, but little is known about plasticity, the higher-order factor that subsumes openness. College students (n = 189) completed measures of the Big Five and measures of creative cognition (fluency and quality of divergent thinking), everyday creative behaviors, creative achievement, and self-rated creativity. Latent variable models found broad effects of openness to experience and few effects of the other four domains. At the higher-order level, plasticity predicted higher scores on nearly all of the facets of creativity, and stability had several significant effects. For some creativity measures, plasticity and stability had opposing effects. Tests of latent interactions found no significant effects: plasticity and stability predict creatively independently, not jointly. 相似文献

Two experiments employed experience sampling to examine the factors associated with a prospective and retrospective focus during mind wandering. Experiment One explored the contribution of working memory and indicated that participants generally prospect when the task does not require continuous monitoring. Experiment Two demonstrated that in the context of reading, interest in what was read suppressed both past and future-related task-unrelated-thought. Moreover, in disinterested individuals the temporal focus during mind wandering depended on the amount of experience with the topic matter—less experienced individuals tended to prospect, while more experienced individuals tended to retrospect. Together these results suggest that during mind wandering participants’ are inclined to prospect as long as the task does not require their undivided attention and raise the intriguing possibility that autobiographical associations with the current task environment have the potential to cue the disinterested mind. 相似文献

Many studies have suggested that a word’s orthographic form must be processed before its meaning becomes available. Some interpret
the (null) finding of equal facilitation after semantically transparent and opaque morphologically related primes in early
stages of morphological processing as consistent with this view. Recent literature suggests that morphological facilitation
tends to be greater after transparent than after opaque primes, however. To determine whether the degree of semantic transparency
influences parsing into a stem and a suffix (morphological decomposition) in the forward masked priming variant of the lexical
decision paradigm, we compared patterns of facilitation between semantically transparent (e.g., coolant—cool) and opaque (e.g., rampant—ramp) prime—target pairs. Form properties of the stem (frequency, neighborhood size, and prime—target letter overlap), as well
as related—unrelated and transparent—opaque affixes, were matched. Morphological facilitation was significantly greater for
semantically transparent pairs than for opaque pairs. Ratings of prime—target relatedness predicted the magnitude of facilitation.
The results limit the scope of form-then-meaning models of word recognition and demonstrate that semantic similarity can influence
even early stages of morphological processing. The research reported here was supported by National Institute of Child Health
and Development Grant HD-01994 to Haskins Laboratories. 相似文献

Information was gathered by means of a questionnaire survey and interviews from a group of patients (N = 17) and health professionals (N=13) working within a stroke unit, concerning the emotional needs of patients and and their relatives and how staff responded to these needs. Although most of the staff had received some training or information about counselling and felt that their interactions with patients often involved an element of counselling, there was strong support for separate specialised counselling services to deal with psychological problems suffered by both patients and their relatives. Patients rated assistance with personal and emotional worries and advice about physical problems as equally useful. A strong need for a counselling service in some form or other was expressed by patients. Neither the level of the patients' social support nor the presence or absence of aphasia, however, predicted the strength of interest expressed. It is concluded that specialised psychological help could be useful in various ways for both in- and out-patients and for their families. 相似文献

Individual differences in the effects of pharmacological and behavioural manipulations on slow cortical potentials (SCP), may reflect personality differences in type of informational control under attentional stress. Two experiments were conducted to examine SCP component differences in extraverts and introverts under different attentional tasks and with and without nicotine smoking ‘stressor’ conditions. In an initial experiment a decrease in late negativity for introverts and an increase in late negativity for extraverts suggested that smoking enhanced introverts' stimulus set and extraverts' motor set. In a second experiment, personality differences in SCP were examined again, but within a signal-detection paradigm, which allows separate assessment of the contribution of sensory sensitivity and response bias factors to performance. Smoking increased sensitivity in both personality groups, but response bias (caution) increased in introverts only. Extraverts showed an increase in central negativity during smoking whilst introverts showed a decrease in negativity and a decrease in positive wave components. The results are explained in terms of a motor model of attentional control whereby smoking regulates inhibitory controlled actions in introverts, but activates general motor processes for extraverts. 相似文献
