大学生消费心理及消费行为的调查与分析

目的 探讨大学生的实际消费心理及消费行为并进行分析.方法 采用问卷调查的方法,并结合一定量的访谈.结果 绝大多数大学生具有健康的消费心理,只有5%左右的大学生具有病态的消费心理,但却有约20%的大学生对消费意义的认知不清.结论 大学生的消费心理及消费行为应受到关注,学校应加强这方面的教育.     

有限自制力的理论假设及相关研究

自我控制与理性和谐的生活秩序息息相关。近十年来关于自我控制的研究表明．自制力类似于肌肉的力量，是有限而易消耗的，休息后能自动恢复；为了克服有限的资源与无限的需要的矛盾．个体倾向于有选择地使用宝贵的自制力资源；通过预期、启动等途径能在一定程度上降低自制力消耗的效应．通过锻炼能够有效地提升自制力的强度。未来的研究最重要的是找到直接测量自制力资源的途径．确立有限自制力理论的说服力。

Recovery of responsiveness of cells of lateral geniculate nucleus of rat

1. Recovery of responsiveness of single cells in lateral geniculate nucleus of rat has been determined in both P and I cells. There are three types of recovery curve among P cells; (a) early recovery, (b) early partial recovery followed by depression and then complete recovery, (c) prolonged depression followed by cyclic recovery. Type (c) is by far the commonest recovery curve. In contrast to the spike in a P cell, the synaptic potential recovers to its full amplitude in about 20 msec. All I cells exhibit similar rapid recovery curves after a prolonged depression.2. Conditioning stimuli applied to visual cortex also produce a prolonged depression in most P cells but I cells can be re-excited at short intervals from cortex. Decortication does not prevent the prolonged depression of the multineuronal response produced by optic nerve stimulation.3. A neuronal model is proposed to explain these observations. It is supposed that I cells (interneurones) are innervated by axon collaterals of the P cells (principal cells, projecting to visual cortex) and that the I cells exert an inhibitory influence on the P cells.     

Modes of Inheritance of Errors of Refraction

Eighteen families in which both parents had refractions within the range of +4·0 D to −4·0 D and axial lengths seen in emmetropia (22·3-26·0 mm) showed coefficients of correlation of the order 0·5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0·407) and for the cornea (0·487), but not for the lens (which is known to be yoked to the axial length). No such coefficients were seen in 19 families in which one of the parents had axial length outside the emmetropic range (nine families with long axes and 10 with short axes).

The pattern of polygenic inheritance for emmetropia (completely correlated optical components) and errors of refraction up to 4·0 D (inadequately correlated components: correlation ametropia) follows that seen in stature and other measurable characters. In contrast the high refractive errors with their abnormal axial lengths (component ametropia) are—like the extremes in stature—pathological anomalies with monofactorial inheritance.

     

Level of functioning of siblings and parents of probands of varying degrees of retardation

A further analysis of already published data supports the position that retardates of low ability level less frequently have retarded siblings, retarded parents, and parents low in occupational level than do retardates higher in ability level. The analysis supports the position that there are two types of retarded individuals, persons retarded as a result of gene or chromosomal anomalies, brain injury, etc., who more frequently occur in the lower-level retardate group, and persons whose retardation represents polygenic segregation, who more frequently occur in the higher-level group.     

Analysis of two types of dopaminergic responses of neurons of the spinal ganglia of rats

It was established, in experiments on isolated spinal ganglia of adult rats in concluons of intracellular recording, that dopamine (1 M/liter) elicits depolarized responses in 61% of neurons, hyperpolarized in 20% of neurons, and depolarized-hyperpolarized in 19% of neurons. The depolarized responses are associated with the activation of D₁ dopamine receptors, and are governed by the shift of cAMP-dependent cation (sodium) channels to the conducting state. The hyperpolarized responses are triggered by the activation of D₂ dopamine receptors, which by means of HTP-binding protein convert the potassium channels to the conducting state. The change in the polarization of neurons with the action of dopamine influences their electrical excitability variously.Translated from Fiziologicheskii Zhurnal SSSR imeni I. M.
