Dynamic organization of intersensory function

Issues related to infant intersensory functioning are reviewed. The argument is offered that limitations of sensory inputs during early stages of development are necessary and provide structure and organization which determine behavioural characteristics at later stages. It is also suggested that infant organisms respond to the intensity of stimulation rather than organizational characteristics and that this is responsible for the form of sensory equivalence apparent during early development. A scheme for the investigation of sources of intersensory organization is presented which involves a prospective analysis of how consideration of the times of onset of sensory functions helps us to understand intra- and intersensory development. The advantages of this experimental approach are outlined.     

The composition of imaginal transformations

Three experiments examine the performance of composite imaginal spatial transformations using tasks in which people perform pairs of distinct imaginal transformations either in close succession or simultaneously. The principal aim of the investigation is to determine, for both modes of composition, whether imaginal transformations combine interactively or noninteractively to determine the temporal course of imaging performance. Specifically, does the time to imagine a given composite transformation reflect the independent contributions of its component transformations, or do component transformations have different effects within different composites? Results obtained under a number of distinct task conditions are most consistent with the proposal of noninteractive composition. However, the temporal effects of particular imaginal transformations are neither consistent nor readily predictable across different task conditions. Implications of these results for analogue-spatial models, task demand, and procedural accounts of imaging are discussed.     

Visual search along the colour dimension

Subjects searched for a chromatic target among coloured background items. With low target-background chromatic similarity, response latencies remained uniformly short whether the target was present or not and whether the items were chromatically homogeneous or not. Latencies increased with increases in target-background similarity and were longest with heterogeneous backgrounds, with which the effects of trial type also became manifest. We employed Treisman's model of visual search to account for these findings. In particular, we suggest that similarity increases forced a shift from a preattentive to an attentive search, the latter being importantly shaped by the background's level of chromatic variance.     

Helping through touch: The embodiment of caring

There is a power to touch, and a magic. Some call it mystery. The purpose of this paper is to reflect on the various meanings and uses of touch, particularly within the context of relationship and helping. There will be no attempt to formulate a protocol for touch or to lay claim to a definitive meaning for touch. Reflection about touch may instead clarify some of its meanings and dynamics while encouraging care providers to embrace the experience of helping-through-touch. This paper supports a considered use of empathie touch because of its power and its ability to embody care.     

A sermon from hell: Toward a theology of loneliness

Loneliness as part of the human condition is first explored from an experiential-philosophical perspective. A biblical survey suggests loneliness is normative to the faith experience and may portray a more realistic religiosity. Desert imagery in Scripture indicates a strong association among solitude, spiritual development, and potential dangers of spiritual deception. God's not yet-ness-itself a cause of existential loneliness—is paradoxically the way in which communion with God functions in the here and now. The creative use of solitude may enhance social, psychological, and spiritual well-being, and provide a way to theologize about personal isolation and disorientation.He is also editor of theHarding Journal of Religion and Psychiatry.     

Effects of aggressive and nonaggressive rock songs on projective and structured tests

The differences between hostility scores on projective and objective tests as a function of listening to aggressive or nonaggressive rock music were studied. While taking the Thematic Apperception Test (Cards 1, 3BM, 4, 9BM, and 10) and the Buss-Durkee (1957) Hostility Scale, subjects (N = 90) randomly assigned to one of three groups listened to a rock song with (a) nonaggressive music and nonaggressive lyrics, (b) aggressive music and nonaggressive lyrics, or (c) aggressive music and aggressive lyrics. TAT stories were scored for aggressive content according to Hafner and Kaplan's (1960) hostility rating scale. Hostility scores did not differ between groups. The findings are congruent with other investigators' reports that subjects do not pay attention to rock lyrics. Previous findings that music affects the emotional quality of TAT stories and hostility scores on the Buss-Durkee scale were not supported.     

Arousal as an explanation for differences in rats selectively bred for differential alcohol sensitivity

A common error made by behavior genetics researchers is breeding two lines for differences in central arousal rather than for a specific behavioral feature. Two lines of rats (Riley, Freed, & Lester, 1976) were selectively bred for locomotor impairment in response to a subhypnotic dose (1.5 g/kg) of ethanol. These lines (designated "most affected" and "least affected") were compared in a variety of tests and showed differences in a number of phenotypic traits in addition to locomotor impairment to ethanol. The published findings have been interpreted in light of a hypothesis suggesting adventitiously selected differences in central arousal between the two lines. This interpretation showed that their usefulness as animal models of alcoholism is seriously compromised.     

Religious celibacy from the celibate's point of view

What do celibates consider the adaptive and maladaptive aspects of their celibate religious lifestyle? What role has celibacy played in understanding the differences between those who persevere and those who choose to resign from celibate religious life and/or ordained ministry? Using data from extensive interviews, this exploratory study begins to focus some of the perceived effects of celibacy upon personal development for both those who persevere in celibate religious life and those who resign.     

On the limits of the matching concept in monkeys (Cebus apella).

Two cebus monkeys, with many years of experience matching a variety of static visual stimuli (forms and colors) within a standard matching-to-sample paradigm, were trained to press a left lever when a pair of displayed static stimuli were the same and to press a right lever when they were different. After learning the same/different task, the monkeys were tested for transfer to dynamic visual stimuli (flashing versus steady green disks), with which they had no previous experience. Both failed to transfer to the dynamic stimuli. A third monkey, also with massive past experience matching static visual stimuli, was tested for transfer to the dynamic stimuli within our standard matching paradigm, and it, too, failed. All 3 subjects were unable to reach a moderate acquisition criterion despite as many as 52 sessions of training with the dynamic stimuli. These results provide further evidence that, in monkeys, the matching (or identity) concept has a very limited reach; they consequently do not support the view held by some theorists that an abstract matching concept based on physical similarity is a general endowment of animals.     

Hypnotic blindness, awareness, and attribution

Examined whether performance on a spelling task would be influenced by visual information in the reported absence of hypnotized subjects' awareness of that information. Experiment 1 visually presented uncommon spellings of homophones to subjects before and during a suggestion for hypnotic blindness, and subsequently tested subjects' spelling of the homophones. Words presented during hypnotic blindness influenced subjects' spelling performance. Subjects' attributions of their performance did not involve awareness of the homophones. Experiment 2 used the nonexperiment methodology to examine the impact of demand characteristics and indicated that the performance attributions of subjects of Experiment 1 could not be explained in these terms. The discussion focuses on implicit perception in hypnotic blindness and on the relevance of attributions about behavioral performance on hypnotic phenomena.
