Representing disability in charity promotions

Social psychological research in relation to charity advertising in the area of disability has attempted to distinguish between ‘positive’ and ‘negative’ images and the way in which these are related to their fundraising potential. In the light of the critique of charity advertising offered by a number of disability theorists, it is suggested that this perspective would be enhanced by consideration of the attitudes of disabled people to charity advertisements. A study is reported that compares the attitudes of disabled and non‐disabled people to two charity advertisements. Differences between these two groups are reported and in the light of the nature of these it is suggested that what are considered to constitute ‘positive images’ is unlikely to be consensual.

Training letter discrimination in four-year-old children

Four-year-old children were tested on letter discrimination. Subjects in two experimental groups went through an experimental training program on a match-to-sample apparatus. Subjects in the experimental-critical group were given reinforcers for responding to features of the stimuli thought critical for discriminating letters while subjects in the experimental-noncritical group were given reinforcers for responding to non-critical features. Subjects went through the training program daily until they reached criterion; then they were posttested on letters. Subjects in a control group received no training but were posttested. Subjects in all groups made fewer errors on the posttest. Subjects in the experimental-critical group made significantly fewer posttest errors than subjects in the experimental-noncritical group, lending support to the hypothesis that reinforcement of discriminative responding to critical features of letter-like stimuli results in greater improvement in letter discrimination than reinforcement of discriminative responding to noncritical features of stimuli. Analysis of confusion matrices provided tentative indications of the nature of letter confusions in 4-yr-old children.     

An empirical basis for charity in interpretation

In codifying the methods of translation, several writers have formulated maxims that would constrain interpreters to construe their subjects as (more or less) rational speakers of the truth. Such maxims have come to be known as versions of the principle of charity. W. V. O. Quine suggests an empirical, not purely methodological, basis for his version of that principle. Recently, Stephen Stich has criticized Quine's attempt to found the principle of charity in translation on information about the probabilities of various sorts of mistakes. Here 1 defend Quine's approach. These issues have important implications for the supposed a priori status of human rationality.     

好意原则的局限性

Radical interpretation is used by Davison in his linguistic theory not only as an interesting thought experiment but also a general pattern that is believed to be able to give an essential and general account of linguistic interpretation. If the principle of charity is absolutely necessary to radical interpretation, it becomes, in this sense, a general methodological principle. However, radical interpretation is a local pattern that is proper only for exploring certain interpretation in a specific case, and consequently the principle of charity is an applicable principle in the limited scope. It is neither the case that every linguistic interpretation is in nature radical nor that the principle of charity is the primary and fundamental principle for all linguistic interpretation as Davidson believes.      

Training strategic study time apportionment in educable retarded children

Two groups of educable retarded children differing in functioning level served as subjects. One group, the High group, consisted of 31 children drawn from the upper two classes of a five-class stream. The Low group consisted of 39 children drawn from the lowest two classes. During pretesting, on each trial but the first of a multitrial free recall procedure, subjects were allowed to select half of the to-be-remembered items to see if they would strategically select missed items for extra study. Following pretesting, subjects were divided for training into three groups for which the experimenter selected items for study: in the Standard group, missed items; in the Creeping group, recalled items plus one missed item; and in the Random group, half missed and half recalled items. Children in the High group improved in the Standard condition, and those in the Low group benefited from Creeping training. There was no evidence of maintenance of training in the Low group, but children in the High group given training in the standard strategy selected missed items for recall on the posttests. The results are discussed in terms of the stability of trained strategies in retardates, and the question of what constitutes an optimal strategy is considered.

Training profoundly retarded children to stop crawling

Many profoundly retarded children continue to crawl even though they can walk. Crawling and walking were viewed as two alternative response modes, both reinforced by movement. Children choose the one mode that is easier and faster for them. A training program was designed to increase the ease and speed of walking relative to that of crawling, and consisted of restraint-for-crawling and priming-of-walking. With the program, four retarded children reduced crawling and began to walk instead. When training was discontinued, two children with moderate walking impairment continued to walk rather than crawl. Two children with severe impairment of walking, however, required the occasional use of the restraint procedure to maintain walking as the dominant mode of locomotion. The program was easily administered, required little time, and was effective for all four children.     

Effects of social labeling on giving to charity

This field experiment tested the hypothesis that social labeling influences an actor's self-concept and his perception of the consequences of his behavior. Subjects who gave to charity were labeled charitable or not labeled and subjects who refused to give were labeled uncharitable or not labeled. Subjects were later asked to contribute to a second charity by a canvasser who was either highly involved in his cause, and hence likely to dispense social reinforcements, or uninvolved in it. Subjects labeled charitable gave more and subjects labeled uncharitable gave less than their respective control groups (p < .05). However, labeling did not cause subjects to distinguish more between the involved and the uninvolved canvassers. All subjects contributed more to the involved than to the uninvolved canvasser (p < .05).     

Training in musical rhythm and field dependence of children.

The present experiment investigated the effects of musical rhythm training on field dependence in children. An experimental group of 12 Ss showed significant improvement on the Children's Embedded-figures Test and the Rod-and-frame Test after training, while a matched control group did not improve. Pretest scores on the children's Embedded-figures Test and the Rod-and-frame Test were not correlated.     

Training and transfer effects of executive functions in preschool children

Executive functions, including working memory and inhibition, are of central importance to much of human behavior. Interventions intended to improve executive functions might therefore serve an important purpose. Previous studies show that working memory can be improved by training, but it is unknown if this also holds for inhibition, and whether it is possible to train executive functions in preschoolers. In the present study, preschool children received computerized training of either visuo‐spatial working memory or inhibition for 5 weeks. An active control group played commercially available computer games, and a passive control group took part in only pre‐ and posttesting. Children trained on working memory improved significantly on trained tasks; they showed training effects on non‐trained tests of spatial and verbal working memory, as well as transfer effects to attention. Children trained on inhibition showed a significant improvement over time on two out of three trained task paradigms, but no significant improvements relative to the control groups on tasks measuring working memory or attention. In neither of the two interventions were there effects on non‐trained inhibitory tasks. The results suggest that working memory training can have significant effects also among preschool children. The finding that inhibition could not be improved by either one of the two training programs might be due to the particular training program used in the present study or possibly indicate that executive functions differ in how easily they can be improved by training, which in turn might relate to differences in their underlying psychological and neural processes.     

Training generalized improvisation of tools by preschool children

The development of new, "creative" behaviors was examined in a problem-solving context. One form of problem solving, improvisation, was defined as finding a substitute to replace the specifically designated, but currently unavailable, tool ordinarily used to solve the problem. The study examined whether preschool children spontaneously displayed generalized improvisation skills, and if not, whether they could be trained to do so within different classes of tools. Generalization across different tool classes was monitored but not specifically trained. Five preschool children participated in individual sessions that first probed their skill at improvising tools, and later trained and probed generalized improvisation in one or more of three tool classes (Hammers, Containers, and Shoelaces), using a multiple-baseline design. All five children were trained with Hammers, two were trained in two classes, and two were trained in all three tool classes. Four of the five children improvised little in Baseline. During Training, all five showed increased generalized improvisation within the trained class, but none across classes. Tools fabricated by item combinations were rare in Baseline, but common in Training. Followup probes showed that the training effects were durable.     

The polite wiggle‐room effect in charity donation decisions

We extend research on charity donations by exploring an everyday tactic for increasing compliance: asking politely. We consider three possible effects of politeness on charity donations: a positive effect, a negative effect, and a wiggle‐room effect where the perception of the request is adjusted to decline donating without feeling selfish. Results from six experiments systematically supported the polite wiggle‐room effect. In hypothetical donations contexts, indirect requests were judged more polite. In real donation contexts, though, indirect requests were not judged as more polite and had no consistent effect on donation decision. Rather, the decision to donate predicted the perceived politeness of the request, independently of its phrasing. Experiment 4 provided causal evidence that participants justified their donation decisions by adjusting their perception of the request. The polite wiggle‐room effect has important implications for organizations that seek to increase compliance while maintaining a positive image.     

Fear-then-relief,legitimizing a paltry contribution,and charity

IntroductionThe compliance literature describes multiple techniques of social influence. Some of them have proven effective at inducing compliance in the charity domain. One such technique is referred to as legitimizing a paltry contribution (LPC). There are theoretical grounds on which it can be assumed that this technique will be particularly effective in conditions in which a person feels relief from fear.ObjectiveThe aim of the study was to examine whether people who experience fear-relief sequences are more susceptible to the LPC technique than those in a neutral emotional state.MethodIn two field studies, some people experienced relief from fear, while others remained in a neutral emotional state. The participants were then asked to donate to a worthy cause. A request was formulated either in a standard way, or with the phrase “even a penny will help”.ResultsThe two experiments yielded consistent results. It turned out that the LPC technique was particularly effective when participants had experienced relief from fear.ConclusionsThe aforementioned pattern of results is important for the development of theoretical knowledge about techniques of social influence, and has direct practical implications.
