知情交互作用的实证研究现状与展望

知情交互作用(the interaction of cognition-emotion)是指认知与情绪之间相互作用,相互影响,二者密不可分.当前,知情交互作用的研究主要涉及两个方面:一是认知对情绪的影响,即认知对情绪的产生和情绪调节的影响;二是情绪对认知的影响,即情绪对感知觉、记忆和思维的影响.本文从实证角度,综合相关文献选取各自领域具有代表性的最新研究成果进行了概要述评,并进一步指出未来的研究应该在无意识情绪的脑机制、情绪-想象的交互作用、情绪-语言的交互作用,以及知-情-行的整合等方面进一步探讨.     

You want to appear competent? Be mean! You want to appear sociable? Be lazy! Group differentiation and the compensation effect

Using the two fundamental dimensions of social judgment, warmth and competence, we show that, contrary to general models of impression formation, negative information on one dimension has positive consequences on the way a target is judged on the other dimension. Participants learned about two groups which were either congruent on warmth and competence (one group high on both and the other low on both) or they were compensatory (one group high on warmth and low on competence, the other high on competence and low on warmth). Our results show that in the compensatory condition, the groups were rated more extremely than in the congruent condition and that this was especially the case for the dimension on which the groups were high. Results are discussed both in terms of how they run counter to traditional theories of impression formation and what they tell us about the fundamental dimensions of social judgment.     

Electrocutaneous stimulation II. The estimation of distance between two points

Using a numerical estimation procedure, subjects judged the perceived distance between pairs of brief electrical stimuli presented over different physical distances, on different body regions, and in different spatial orientations. The skin turns out to be anisotropic, with the same physical separation between electrodes appearing greater on the forehead than on the forearm, greater on the forearm than on the abdomen. Perceived distance also depends on the orientation and, to some extent, on the time relation between the two electrical pulses. Under all conditions, the perceived distance between electrical stimuli was “compressed” as compared with visual distance. These results bear on the design of devices that attempt to transmit information by electrical stimulation of the skin.     

Two Factors to be Considered in the Design of Experiments in Anxiety and Motor Behavior

The authors examined the influence that attentional focus on either a postural or a suprapostural task had on the performance of each task. Participants (N = 32) stood on an inflated rubber disk and held a pole horizontally. All participants performed under 4 attentional focus conditions: external (disk) or internal (feet) focus on the postural task, and external (pole) or internal (hands) focus on the suprapostural task. Compared with internal focuses, external focuses on either task resulted in similar and reduced postural sway. Response frequency on each task increased when participants focused on the respective task. Finally, an external focus on either task produced higher frequencies of responding on the suprapostural task. The authors conclude that suprapostural task goals have a stronger influence on postural control than vice versa, reflecting the propensity of the motor system to optimize control processes on the basis of the desired movement effect.     

Conditioned suppression of counting behavior in rats

Three rats were trained on a schedule in which a response on lever B was reinforced only if it was preceded by a minimum number of consecutive responses on lever A. The minimum requirement was 27 A responses for Rat 1, and 20 A responses for Rats 2 and 3. The schedule maintained high rates of responding on lever A, and a slow, spaced pattern of responding on lever B. The mean number of consecutive responses on lever A was slightly greater than the minimum required. The effect of superimposing on this behavior a stimulus that ended with an unavoidable shock was the suppression of responding on both levers during the pre-shock stimulus. Responses on lever A were more suppressed, and the proportion of relatively short response runs on lever A during the pre-shock stimulus increased. With all three rats, the mean number of consecutive responses on lever A during the pre-shock stimulus decreased to a value below the minimum requirement for reinforcement of the subsequent B response.     

Reciprocal influences of attentional focus on postural and suprapostural task performance

The authors examined the influence that attentional focus on either a postural or a suprapostural task had on the performance of each task. Participants (N = 32) stood on an inflated rubber disk and held a pole horizontally. All participants performed under 4 attentional focus conditions: external (disk) or internal (feet) focus on the postural task, and external (pole) or internal (hands) focus on the suprapostural task. Compared with internal focuses, external focuses on either task resulted in similar and reduced postural sway. Response frequency on each task increased when participants focused on the respective task. Finally, an external focus on either task produced higher frequencies of responding on the suprapostural task. The authors conclude that suprapostural task goals have a stronger influence on postural control than vice versa, reflecting the propensity of the motor system to optimize control processes on the basis of the desired movement effect.

The role of the cs and avoidance period duration in discriminated avoidance conditioning

In an experiment investigating the effect of CS duration on discriminated bar-press conditioning, subjects were assigned to one warning period duration (1.5, 5.0 or 15.0 sec.) on the first day of avoidance training, and to one of the three durations on the second day of training. On each day avoidance behaviour was greatly influenced by the duration of the CS (warning) period, but the duration on day I had no effect on the second day's avoidance performance. Groups receiving no CS during training, although provided an avoidance contingency, showed little conditioning, but produced highly significant amounts of intertrial responding. In a second experiment, subjects receiving CS on day I were shifted to no CS on day II. Avoidance performance on day II was not significantly different from the day II performance of subjects in Experiment I having two training sessions with the CS present or absent on both days.

The big friendly counter-space? Interreligious encounter within social media

ABSTRACT

Research on interreligious dialogue mostly focuses on face-to-face meetings, however, it also takes place in other contexts. Among them is the huge space of interactive media, where adherents of different religious traditions meet, e.g., in interreligious groups on Facebook, boards or commentary sections – but so far little has been researched on this field. The article is an explorative attempt to sort the field of interreligious dialogue and encounter in social media, drawing on a comparative perspective on the field of offline interreligious dialogue. For this purpose, it first gives a systematizing overview of the existing research on interreligious encounter in social media as well as on (offline) interreligious dialogue, identifying key questions and issues on interreligious encounter. Examples from different social media platforms then allow conclusions about commonalities and differences between online and offline interreligious encounter and suggest crucial aspects to follow up on in future research on this field.

Species differences in temporal control of behavior II: human performance

Human subjects responded on two panels. A differential-reinforcement-of-low-rate schedule with a limited-hold contingency operated on Panel A. In Condition 1, responses on Panel B produced a stimulus on the panel that signalled whether reinforcement was available on Panel A. In Condition 2, responses on Panel B briefly illuminated a digital clock. In both conditions, performance on Panel A was very efficient; with few exceptions, Panel A was pressed only when reinforcement was available. Thus, in effect, a fixed-interval schedule operated on Panel B. In Condition 1, a “break-and-run” response pattern occurred on Panel B; with increasing temporal parameters, the duration of the postreinforcement pause on Panel B increased linearly while overall response rate and running rate (calculated by excluding the postreinforcement pauses) remained approximately constant. In Condition 2, the response pattern on Panel B was scalloped; the postreinforcement pause was a negatively accelerated increasing function of schedule value, while overall response rate and running rate were negatively accelerated decreasing functions of schedule value. The performance of subjects in Condition 2, but not in Condition 1, was highly sensitive to the contingencies in operation, and resembled that of other species on the fixed-interval schedule.

Positive conditioned suppression: Transfer of performance between contingent and noncontingent reinforcement situations

Five homing pigeons were trained on concurrent variable-interval schedules. A fixed-duration stimulus was occasionally presented on one key; and, in various conditions, this stimulus terminated (a) without reinforcement, (b) in noncontingent reinforcement, (c) with reinforcement contingent on a response on the key on which the stimulus was presented, and (d) with reinforcement contingent on a response on the key on which the stimulus was not presented. Initially, a stimulus terminating in noncontingent reinforcement generally produced decreased response rates on both keys during the stimulus. Contingencies, however, reliably produced increased rates during the stimulus on the key on which the contingency was arranged, relative to the rate on the concurrently available key. Contingency conditions were followed by noncontingency conditions in which the separation of rates caused by contingencies was maintained. When rates during the stimulus were compared with response rates on the same keys in the absence of the stimulus, contingency-caused rate increases and decreases were again found, but only the rate decreases were maintained in subsequent noncontingency conditions. Further data suggested that the contingency-caused rate changes were not maintained when the stimulus terminated without reinforcement, and that they were unaffected by a threefold decrease in the reinforcement rate provided by the baseline schedules. The results support the suggestion that performance in the positive conditioned suppression procedure results from concurrent and multiple schedule interactions. They further suggest that the production of either acceleration or suppression is dependent on adventitious and historical contingencies.     

Combining Emotion Appraisal Dimensions and Individual Differences to Understand Emotion Effects on Gift Giving

Multiple studies have revealed that emotion appraisal dimensions can predict the effects of emotions on decision making. For example, givers' intention to buy gifts depends on whether they feel positive or negative (valence) and on whether the feeling is caused by the givers themselves or by gift receivers (agency). However, there is little understanding of how the effects of such appraisal dimensions might depend on individual characteristics. The current research addresses this gap by studying the interaction effects of emotions and individual characteristics on gift giving. Study 1 demonstrates that emotion effects on gift‐giving behavior are explained by two things: the cause of those emotions (self or others, agency) and whether those emotions are positive or negative (valence). Moreover, four studies reveal that these effects depend on the givers' interpersonal orientation. For high interpersonally oriented givers, who care mostly about interpersonal relationships, emotion effects on gift giving depend on both valence and agency. In contrast, for low interpersonally oriented givers, who care mostly about their own gains, emotion effects on gift giving depend only on valence. Together, these findings suggest that although a focus on appraisal dimensions can be useful, individual characteristics should also be taken into account when trying to understand emotion effects on gift giving, in particular, and on decision making, in general.

Social comparison on two dimensions

In this experiment social comparison on two task dimensions has been studied. The subjects received bogus feedback on their performance on two tests, one allegedly measuring creativity, the other alertness. By means of this feedback four relative position conditions were induced: scoring high on both tests, scoring low on both tests, scoring high on creativity and low on alertness, and vice versa. Anticipating either a co-operative or a competitive game, the subjects indicated their preference for one or the other task dimension and also expressed their preference for a comparison person. It was found that, as predicted, the subjects preferred and valued comparison dimensions on which they occupied a favourable position. With respect to preference for a comparison person, compensatory choices were obtained: on the dimension on which the subject performed well, they preferred an inferior other. On the dimension on which they performed poorly, they preferred a superior other. This pattern of choices was found in co-operation as well as in competition. Finally, upward preference was stronger in co-operative than in competitive conditions, particularly on the dimension on which the subject's own score was low. These and other results were discussed in relation to theoretical social comparison notions.     

Welfare policies and adolescents: exploring the roles of sibling care, maternal work schedules, and economic resources

This study uses data from three longitudinal experimental evaluations of US state welfare reform programs to examine whether program‐induced changes in families' reliance on sibling care are linked with the effects of welfare programs on selected schooling outcomes of high risk, low‐income adolescents. The findings from two of the welfare programs indicate that increased reliance on sibling care was concomitant with unfavorable effects of the programs on adolescent schooling outcomes. In the third welfare program examined, the program did not yield any increases in the use of sibling care or unfavorable effects on adolescent schooling outcomes, suggesting that sibling care is one likely contributor to the negative effects of welfare programs on adolescent schooling outcomes. These findings are discussed in terms of the pattern of the programs’ effects on families' income, as well as maternal work on nonstandard schedules, aside from the programs’ effects on maternal employment, which play contributory roles in shaping the extent to which welfare programs led to less favorable effects on the schooling outcomes of adolescents with younger siblings.     

A note on the gross configurations of the human auditory cortex

Gross inspection of 30 human brains (60 hemispheres) from patients without hearing impairment revealed the following configurations of gyri: one on left and two on right (14 of 30); two on left and two on right (11 of 30); one on left and one on right (3 of 30); two on left and one on right (1 of 30); and two on left and three on right (1 of 30). The last group has since been extended to include all combinations other than the first four and the proportions of these combinations appear to persist in larger tallies. Thirteen of the 30 brains displayed double gyri on the left while 25 had double gyri on the right. Seventeen of the 30 brains possessed a single gyrus on the left and four specimens had a single gyrus on the right. In general, the left side has a tendency to fewer gyral markings. The average cortical surface area on the left is 1198 mm² compared to 1380 on the right.     

Specific internal and external attentional focus instructions have differential effects on rowing performance

Directing an individual to focus their attention on internal or external cues can influence performance of skill-based and endurance sports. The present study examined the effects of switching attention across different types of internal and external attentional foci in a rowing task. Novice rowers (19 male, 47 female) focussed attention on one of four different internal cues (or one of four different external cues) at discrete time points while completing a row on an ergometer. Overall, a focus on internal cues resulted in longer distance, higher power output, and higher heart rate than a focus on external cues. However, for the internal condition a focus on arm and leg muscles was associated with higher performance than a focus on breathing. For the external condition, a focus on exerting force on the handle produced higher performance than a focus on the movements of the handle or seat or on the sounds of the ergometer. Global instructions to focus internally or externally influenced performance, but the specific effects within these broad categories were also variable. The advice given to athletes and recreational exercises should consider both the broad attentional focus direction and the specific cues of the task to which attention is directed.
