风险决策任务中时间距离对框架效应的影响

通过考察中国大学生时间距离的认知相关性,并进而探讨时间距离对风险决策任务加工方式及框架效应的影响.实验一通过问卷调查发现,与发生时间相对较远的事件相比,相对较近的事件,其认知相关性更大,验证了时间距离的认知相关性假设.在此基础上,以时间距离为自变量,设计小同的风险决策任务,考察框架效应发生的可能性(实验二、实验三).结果显示,时间距离近时,框架效应不明显;时间距离远时,框架效应明显.其原因是,发生在相对不远的将来事件引起分析加工模式,导致框架效应的减弱;发生在相对远的将来事件引起整体加工模式,导致框架效应的增强.     

The differential processing of price in gains and losses: the effects of frame and need for cognition

Perhaps the most fundamental principle of decision theory is that more money is preferred to less: the principle of desired wealth. Based on this and other principles such as reference dependence and loss aversion, researchers have derived and demonstrated mental accounting (MA) rules for multiple outcome situations. Experiment 1 tested the invariance of the desired wealth principle and two mental accounting rules (mixed gain, e.g. $100 gain and a $50 loss; mixed loss, e.g. $100 loss and a $50 gain) across types of decision maker and frame. The desired wealth principle and the MA rule for mixed gains were found to vary depending upon (1) the thoughtfulness of the decision maker (need for cognition, NC), and (2) the frame used to describe gains and losses (e.g. a gain of $x versus a gain of y%). The MA rule for mixed losses, however, was found to be immune to framing effects, even among people who are generally less thoughtful. The differential processing of gains and losses across frames (dollar versus percentage) and individuals (less versus more thoughtful) was tested further in Experiment 2 where evaluations of mixed losses were made at the level of the gestalt as well as the constituent (the gain and the loss being evaluated separately). Framing effects were evidenced only among subjects lower in NC and only when the constituent gain was evaluated. Evaluations of the overall mixed loss and the constituent loss were comparable across situation and individual, suggesting that losses motivate greater processing among people otherwise inclined toward cognitive miserliness.

内隐态度实验研究:加工水平与黄,白,黑情感态度

研究使用肯定词和否定词分别与黄、白、黑三字搭配的实验卡片。随机抽取医学院本科生34名,采用2种加工水平×3种测量目标的混合设计来考察态度情感特征的无意识性。结果发现：1）加工水平对被试的自我报告和线索提取有不同的影响,即自我报告受加工水平影响,线索提取不受加工水平影响,发生实验性分离;2）加工水平对被试态度的实验性分离也有不同影响,即概念加工下出现高度分离,数据加工下则低度分离,3）经过改造的语义线索法是测量内除态度的有效方法。

Information processing in chronic pain disorder: A preliminary analysis

Researchers have alternately suggested selective attention, impaired stimulus filtering, and affective language deficiency models as accounting for multiple somatic complaints in persons with chronic pain disorder. The purpose of the present study was to establish the comparative usefulness of these three models for explaining somatic focus in a chronic pain population. Nine chronic pain patients evidencing high somatic focus (somatizing chronic pain patients), 10 chronic pain patients evidencing low somatic focus (nonsomatizing chronic pain patients), and 10 healthy control subjects were administered a computerized version of the emotional Stroop test as a test of these models. A total of 105 pain-, depression-, and neutral-content words were used as Stroop test stimuli. Stroop test color-naming response latencies were submitted to a two-way Group × Word Type mixed-model ANOVA, with Word Type as the repeated measure. Results reveal that neither the selective attention model nor the affective language deficiency model adequately explain Stroop test performance in somatizing chronic pain patients. Findings provide tentative support for the impaired stimulus filtering model, with somatizing chronic pain patients evidencing similar Stroop test response delays across all words. These results suggest that chronic pain sufferers misinterpret bodily sensations. Findings are discussed in terms of a bilevel approach for treatment of somatizing chronic pain patients that would include assisting the patient in accurate appraisal and interpretation of physical symptoms.     

Affective information processing and the assessment of anxiety

A conceptualization of anxiety as comprising three loosely coupled response systems of overt behavior, verbal report, and physiological activation has proven useful in clinical and theoretical work. With this framework as a starting point, an information-processing approach to the study of emotion is described. Emotions are conceived as affective programs within the brain, with information coded as propositions organized into associative networks. Affective expression results when such a network is accessed and processed, which can occur when a sufficient number of propositions are activated by environmental stimuli and/or internal associations. It is hypothesized that information about the expressive physiology is an integral component of the associative structure, and that processing of the network accordingly results in measurable psychophysiological response. Data from studies of emotional imagery, as well as other areas of research, are reviewed in support of these theories. The utility of this approach for the assessment of anxiety disorders is discussed, and results of clinical studies are presented to suggest that individual differences in accessing and processing emotional information may bear significant implications for prognosis and treatment selection. It is speculated that differences among the anxiety disorders could be interpreted in terms of the degree of cognitive organization of the network, leading to potential refinement of current diagnostic categories. In conclusion, cognitive psychology paradigms are discussed in terms of their application to the assessment and treatment of anxiety disorders.The authors' research is supported in part by NIMH Grant MH 37757. Portions of this paper were presented at the NIMH Conference on Anxiety, Tuxedo, NY, September 1983. Several of its themes were developed there at more length, and this material may be found in the publication of the conference proceedings (Tuma & Maser, 1985).
