Cardinal coordinate independence for expected utility

A representation theorem for binary relations on $\text{R}$ⁿ is derived. It is interpreted in the context of decision making under uncertainty. There we consider the existence of a subjective expected utility model to represent a preference relation of a person on the set of bets for money on a finite state space. The theorem shows that, for this model to exist, it is not only necessary (as has often been observed), but it also is sufficient, that the appreciation for money of the person has a cardinal character, independent of the state of nature. This condition of cardinal appreciation is simple and thus easily testable in experiments. Also it may be of help in relating the neo-classical economic interpretation of cardinal utility to the von Neumann-Morgenstern interpretation.     

Reversible operations in the balance scale task

The development of two types of reversible operations was examined in three tasks involving a two-armed balance scale. The first type of reversible operation, compensation between dimensions, was shown to undergo considerable development between eighth grade and college. Even eighth graders were inconsistent in applying compensation to those versions of the balance scale task that required it. Some subjects, primarily preschoolers, used the given information in a way that was the opposite of that required for correct answers, a result that has been reported for other tasks requiring compensation. A second type of reversible operation, termed “correspondence of patterns”, was also tested and it was tentatively concluded that the responses of the modal college student are not fully reversible in this sense. This finding is also similar to results obtained in judgments of time, speed, and distance and in social judgment studies with college students.     

Development of phonetic memory in disabled and normal readers

The development of phonetic codes in memory of 141 pairs of normal and disabled readers from 7.8 to 16.8 years of age was tested with a task adapted from L. S. Mark, D. Shankweiler, I. Y. Liberman, and C. A. Fowler (Memory & Cognition, 1977, 5, 623–629) that measured false-positive errors in recognition memory for foil words which rhymed with words in the memory list versus foil words that did not rhyme. Our younger subjects replicated Mark et al., showing a larger difference between rhyming and nonrhyming false-positive errors for the normal readers. The older disabled readers' phonetic effect was comparable to that of the younger normal readers, suggesting a developmental lag in their use of phonetic coding in memory. Surprisingly, the normal readers' phonetic effect declined with age in the recognition task, but they maintained a significant advantage across age in the auditory WISC-R digit span recall test, and a test of phonological nonword decoding. The normals' decline with age in rhyming confusion may be due to an increase in the precision of their phonetic codes.     

Noncanonical orientation without occlusion: Children's drawings of transparent objects

The use of a transparent model in a drawing task allows all the features of the model to remain visible whatever its orientation. N. H. Freeman (1980, Strategies of Representation in Young Children, New York/London, Academic Press) found that when drawing a transparent glass with its handle turned away, children made more canonical errors (drawing the handle at the side) than when drawing a similarly orientated opaque cup. According to Freeman being able to see the handle in a noncanonical orientation “triggers” a canonical representation of the object (N. H. Freeman 1980, p. 252). Two experiments are reported which investigated children's drawings of transparent objects. The drawings obtained from children between 4 and 7 years old produced two major findings. First, the tendency toward canonicality when drawing a glass with its handle turned away was significantly reduced when two glasses in differeing orientations were presented side by side. Second, the number of canonical errors was lower when the glass was filled with milk (thus hiding the handle). This latter finding confirms that of N. H. Freeman (1980). However, the first suggests that children use situationally appropriate information when drawing transparent objects in a way similar to that noted by A. M. Davis (1983, Contextual Sensitivity in Young Children's Drawings, Journal of Experimental Child Psychology, 35, 478–486) using opaque objects.     

The role of the magazine-response contingency on signal-directed responding in pigeons

Three experiments used a procedure for directly delivering water into the thirsty pigeon's mouth to explore the role that the instrumental magazine contingency plays in autoshaped responding. Magazine training was accomplished by requiring birds to contact a “magazine” key when it was illuminated, in order to obtain intraoral injections of water. Other subjects received water injections independent of a magazine-response contingency. Subsequently, magazine-trained subjects showed a transient enhancement in responding to the illumination of another “signal” key, whether that stimulus was presented alone or paired with water delivery. The overall level of maintained autoshaped responding was little influenced by the instrumental magazine contingency, although the within-trial time course of signal-directed responding was affected. When illumination of the signal key preceded access to water only when the signal was not contacted, pigeons directed many responses toward the signal key. However, there was no evidence that the instrumental magazine contingency enhanced responding on this omission schedule of reinforcement. These results thus confirm a small, but measurable contribution of the magazine-response contingency to signal-directed responding; they fail to support the conclusion that the instrumental magazine contingency greatly affects the outcomes of autoshaping studies.     

A case of acquired aphasia and convulsive disorder: some linguistic aspects of recovery and breakdown

Among the cases of acquired aphasia and convulsive disorder several children are reported to have experienced more than one aphasic period. We present such a case in more detail, with emphasis on some characteristics of spontaneous speech. The occurrence of paraphasias, and in particular of neologisms, appeared to be associated with language recovery and breakdown. At the beginning of the period of recovery, a rapid and total disappearance of neologisms was observed, while only literal paraphasias remained. A period of language breakdown was preceded by the return of neologisms. The process was not influenced by drug therapy.     

Stuttering and anxiety: The difference between stutterers and nonstutterers in verbal apprehension and physiologic arousal during the anticipation of speech and non-speech tasks

To test if stressful anticipation of speech situations is a factor in eliciting stuttering behavior, the difference between 24 stutterers and 24 nonstutterers in verbal apprehension and physiologic activity was studied before and during speech tasks (reading and conversation), and nonspeech tasks (motor and intelligence task).Results indicate that the difference between stutterers and nonstutterers mainly were restricted to anxiety ratings assessed after each task. Heart rate, vasomotor responses, and electrodermal activity recorded before and during speech tasks were higher compared with the physiologic activity before and during nonspeech tasks but, unexpectedly, this was also the case for nonstutterers. It is concluded that stuttering is not elicited by anxiety.     

Psychology and social control

The history of social control applications of psychology and the likelihood of a future increase in their importance are assessed. The effects of military funding of psychological research and the social consequences of very widespread unemployment are specifically considered. It is argued that psychology and related areas of cognitive science and neuroscience may well become increasingly relevant in the development of the technical components of such techniques rather than in providing ideological justifications for their use.     

Social skills training and systematic desensitization in reducing dating anxiety.

Cooper et al. (1969) have criticized the types of target behavior chosen for therapy analogue studies for being irrelevant to clinical practice. A potential target behavior which appears to be pervasive, complex and directly relevant to clinical practice is interpersonal anxiety. Of special concern to college students is the interpersonal anxiety elicited by members of the opposite sex. especially in dating situations (Martinson and Zerface, 1970).An individual may experience interpersonal anxiety because of a deficit in social skills (reactive anxiety) or because of prior conditioning (conditioned anxiety) or because of some combination of both reactive and conditioned components. While it is possible that a treatment program aimed at a reduction of either of these anxiety components may be instrumental in ameliorating the other component, it would appear that a comprehensive treatment program would attempt to teach social skills as well as reduce conditioned anxiety.Desensitization procedures have demonstrated success in alleviating conditioned anxiety for a wide variety of clinical problems (Paul, 1969a. 1969b) and appears to be a logical choice for the conditioned component of dating anxiety. A number of outcome studies have reported some success in the use of in vivo desensitization (Rehm and Marston, 1968; Martinson and Zerface, 1970) and systematic desensitization (Stark, 1970) in reducing anxiety in date anxious subjects.The literature on treatment programs aimed at social skills training for date anxious subjects is meager. Melnick (1973) reported success in improving the appropriateness of the social behavior of subjects who had experienced a minimal dating history by the use of modeling, behavioral rehearsal and self-observation techniques.The present study was designed to test the relative effectiveness of two different types of treatment programs in alleviating interpersonal dating anxiety. The two experimental groups consisted of a systematic densensitization program which focused on the condition anxiety component and a social skills training program which focused on the reactive anxiety component.
