A continuum of dimensional separability

Recent studies of children’s perception may be interpreted in terms of a developmental continuum from integrality to separability in the perception of multidimensional variation. Two experiments examined the existence of such a continuum in adult perception. The first experiment indicated that there are dimensional combinations that are neither clearly integral nor separable for adults. Rather, such a combination results in performance patterns intermediate between those found with integral and separable dimensions. The second experiment tested one conceptualization of a continuum of dimensional separability in a speeded classification task. By this conceptualization, the perceived structures of multidimensional variation are orderable by thedegree to which the component dimensions are differentiated. Consistent with this view, performances with three-dimensional combinations are shown to be differentially dependent on dimensional and wholistic relations. The importance of the joint consideration of developmental and adult issues in the perception of multidimensional variation is briefly discussed.     

Ethology,ethogeny, etics,emics, biology,culture: On the limitations of dichotomies

Ethogeny, supposedly patterned on ethology, differs as an approach to human social behaviour in obvious respects. Ethogenists follow an emic research strategy, whereas human ethologists have strongly favoured etic research options. However, recent trends to a broader, evolutionary approach in human ethology suggest that an avoidance or rejection of verbal reports and ethogenic methods merits reconsideration, The distinctions involved in the eticlemic contrast are examined, and compared to Richer's distinction between D- and N-type agreements. It is argued that none of the distinctions are dichotomous. The useful aspects of the distinctions refer to the generality of findings, and the validity of evidence. Bearing these in mind, ethogenic methods have a place in a broader human ethology. So far as validity is concerned, the value of a comparison of information from different sources, such as verbal and non-verbal data, is stressed. So far as generality is concerned, ethogenists may consider this to be very limited because of idiosyncratic cultural factors in the causation of human social action. A reconsideration of the biology/culture dimension in terms of function rather than causation may lead to more optimism in this respect, and be more productive scientifically.     

Contextual facilitation in a letter search task depends on how the prime is processed

In a variety of situations it has been observed that the processing of a verbal stimulus is facilitated when it is preceded by an associated word. This article is concerned with determining whether such facilitation occurs automatically upon prime presentation or whether facilitation depends on the manner of processing the prime. Experiment 1 demonstrated that a letter search in a target word was facilitated when the target was preceded by either an identical or semantically associated word. If, however, a letter search was required in the prime as well as in the target (Experiment 2), the relative advantage enjoyed by targets preceded by identical-word primes disappeared. Experiment 3 replicated this loss of facilitation using semantically associated word pairs. Contextual facilitation thus appears to depend upon the mode of analysis of the prime. If the prime is analyzed as a meaningful unit, facilitation occurs. If, however, it is subjected to a more discrete, letter-by-letter analysis, the priming effect vanishes.     

Noise and levels of processing

Three experiments investigated the view that people make more use of relatively surface levels of coding when noise is present, neglecting semantic levels of analysis. In experiment 1 subjects classified words in different ways and then recalled as many as possible. Subjects who received the noise conditions in the order noise-quiet recalled more words than those who received the conditions in the order quiet-noise, but noise failed to interact with the nature of the classification conditions although the usual advantage of the semantic condition over letter-case and rhyme conditions was obtained. Experiment 2 failed to show any effect of noise on physical-name match differences when letter pairs were presented simultaneously. In experiment 3 a delay was introduced between the letters; the noise-quiet subjects were then faster on the physical match than the name match whereas the slower quiet-noise subjects showed the reverse pattern. This could represent an instance of asymmetric transfer from noise to quiet or it could be due to speed per se.Overall, these results argue against a general explanation of noise effects in terms of a passive shift in levels of processing.     

Training severely and profoundly mentally handicapped nocturnal enuretics

The problem of nocturnal enuresis in the institutionalized mentally handicapped is a major one which reduces independence in many handicapped adults and has major implications for hospital resources. Much work, which has looked at initial success rates, relapse rates, and factors involved in these, has been carried out with non-handicapped populations. However, there have been remarkably few such studies with the mentally handicapped. A study is reported in which five severely and profoundly mentally handicapped adolescents or young adults were successfully trained over periods ranging from 18 to 92 weeks. Several interesting features of the data are discussed.     

Religion and mental health among blacks

The positive role of religion in the mental health of black Americans is a much neglected theme in the literature. This paper considers religion as one of the important retained black cultural traits, which continues to play a vital role in the mental health and survival strategies of black Americans. The paper examines Grier and Cobbs's appraisal of the religion-mental health connection in black communities and identifies different ways for mental health practitioners to think about religious phenomena and the primal partnership between religion and mental health. The paper concludes with a challenge to keep awareness of the religion-mental health partnership together in the treatment of black Americans.This paper was originally presented at a two-day conference on Some Dynamics and Psychotherapeutic Methods in Rendering Treatment to Blacks, March 15 and 16, 1980, in Oakland, California. This particular paper discussed religion as one of the important retained black cultural trains.     

Toward a reconceptualization of the reciprocal imitation phenomenon: Two experiments

This paper reports two experiments which consider the increased imitation exhibited by models who have been imitated. Experiment 1 was concerned with whether the reciprocal imitation effect is really reciprocal or if the subsequent imitation will generalize to someone else. It was found that adult subjects who were previously imitated at the 75% rate on a perceptual judgments task subsequently imitated their partner more, rated their partner more attractive, and felt more confidence when imitated than did subjects imitated at the 25% rate. These results were obtained regardless of which confederate the subjects imitated, thus indicating that reciprocal imitation is not necessarily reciprocal, but is generalizable. Experiment 2 assessed whether the subsequent imitation is the product of the effects of being imitated or is the result of the subject observing the imitator's imitation. The results indicated that after having observed imitation at a 75% rate, adult onlookers are more likely to subsequently imitate and be attracted to the imitator, the imitated person, and a person new to the situation than are onlookers who observed a 25% imitation rate. A theoretical modification is advanced which holds that subsequent imitation effects, whether from observing others imitate or from being the target of the imitation, result from a process of imitation of imitativeness. The results of these two experiments have implications for theory in imitation and social learning.
