Interparental conflict and adolescent problem behavior: an examination of mechanisms

The purpose of the present study was to examine several competing hypotheses which have been utilized to explain the negative relationship between interparental conflict and child/adolescent problems. These mechanisms of operation have included modelling, genetic transmission, disrupted parenting, the role of perceptual/appraisal processes of the conflict, and an inhibition hypothesis. One hundred and forty-two young adolescents and their mothers served as subjects. Eighty were from intact families and 62 from recently divorced families. Data were collected from the perspective of the adolescent, mother, behavioral observer, and social studies teacher. The results indicated that intact and divorced samples had to be considered separately as different pathways contributed to adolescent behavior problems in the two samples. For externalizing problems, a direct path between interparental conflict and problem behavior existed for the divorced sample whereas an indirect path through the adolescent's perceptions of the conflict existed for the intact sample. The different context in which the interparental conflict occurred for the two samples was offered as an explanation of this difference. For internalizing problems a significant direct path existed between conflict and problem behavior for both samples; however, the indirect paths through the adolescent's perceptions and through poor parenting skills contributed only for the divorced sample. The results suggest that various mechanisms appear to operate in influencing how interparental conflict influences behavior problems of young adolescents. Both the type of problem examined and the marital status of the parents appear important in determining the relative impact of the mechanisms. Implications for the behavior therapist are noted.     

Applied tension, applied relaxation, and the combination in the treatment of blood phobia

Thirty patients with phobia for blood, wounds and injuries were treated individually with applied tension, applied relaxation, or the combination of these two methods for 5, 9 and 10 sessions, respectively. They were assessed on self-report, behavioral and physiological measures before and after treatment, and at a 6-month follow-up. All groups improved significantly on 11/12 measures, and the improvements were maintained at follow-up. Applying stringent criteria, 73% of the patients were clinically improved at the end of treatment and 77% were so at follow-up. Despite a failure to find between-group differences, on many measures there was a trend favoring applied tension. Since this method is as effective as the other treatments in only half the time, applied tension should clinically be the treatment of choice for blood phobia.     

Infants' perception of rhythm: categorization of auditory sequences by temporal structure

We presented 7- to 9-month-old infants with repetitions of three- or four-tone sequences characterized by a particular rhythmic structure. We then evaluated their detection of changes in rhythmic structure in the context of randomly presented variations in tempo (rate) and frequency. Infants successfully differentiated between three-tones sequences with 1, 2 (X XX) and 2, 1 (XX X) structure as well as four-tone sequences with 2, 2 (XX XX) and 3, 1 (XXX X) structure. In other tasks, they indicated their ability to discriminate between contrasting tempos in the context of frequency variations. We conclude, then, that infants can categorize auditory sequences on the basis of rhythm and also on the basis of tempo.     

Can we imagine how objects look from other viewpoints?

Many psychologists who study cognition believe that perception achieves object-centered representations that make it possible to extract representations of how the object would appear from differing viewpoints. Others believe we can achieve representations of how an object would appear by a process of visualization or mental rotation. We report experiments in which the subject tries to imagine how three-dimensional novel wire objects would appear from positions other than the one they are in. Subjects are unable to perform this task unless they make use of strategies that circumvent the process of visualization. It is suggested that the linear increase in time required to succeed in mental rotation tasks as a function of the angular discrepancy between the figures compared is the result of increasing difficulty rather than of the time required for rotation.     

Patterns of movement in the first 6 months of life: new directions

The field of infant perceptual development has relied heavily on the preferential-looking and habituation paradigms. Despite the obvious advantages of employing standardized methodologies, there is a need to study how perceptual variables give rise to and guide action beginning in the neonatal period. It is argued here that, in the first 5 months of life, it is important to distinguish reflexive patterns of movement from voluntary and cortically controlled patterns. Some criteria are defined. This paper describes three experiments which utilized movement counters to record developmental changes in the frequency and synchrony of limb movements in infants under 5 months. The results show that there is a general increase in frequency of limb movements from 1 to 5 months, but with a plateau or even a decrease in activity from the middle of the third month to the end of the fourth month. It was also demonstrated that synchrony scores (co-activation) for pairs of limbs showed significant increases from 1 month to 5 months. Finally, in all three experiments the presentation of an attractive toy resulted in suppression of activity. The results of the three experiments are interpreted to measure a gradual increase in cortically controlled movement patterns.     

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.     

The psychology of knights and knaves

Knight-knave brain teasers are about a realm in which some people, knights, tell only truths, whereas all others, knaves, tell only lies. For example, suppose person A says, "I am a knight and B is a knight," and person B says, "A is a knave." Is A a knight or a knave? Is B a knight or a knave? In a pilot study, we asked subjects to think aloud while solving problems like these. Their statements suggested that they were making assumptions about the knight/knave status of the characters and drawing deductive inferences from these assumptions to test their consistency. This encouraged us to model the process by means of a simulation based on an earlier natural-deduction theory of reasoning. The model contains a set of deduction rules in the form of productions and a working memory that holds a proof of the correct answer. The greater the number of steps (assumptions and inferences) in the proof, the greater the predicted difficulty of the puzzle. The experiments reported here confirmed this prediction by showing that subjects were more likely to make mistakes (Experiment 1) and take longer to solve (Experiment 2) puzzles associated with a larger number of proof steps.     

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.
