Coping with a threat to life: A longitudinal study of self-concept,social support,and psychological distress

The relationship of self-concept (self-esteem and mastery) and social support to psychological distress was studied among 68 Israeli women immediately prior to undergoing biopsy for suspected cancer (acute stress) and 3 months later for the noncancer group (everyday stress). It was predicted that women with stronger self-concepts and more social support would experience less state depression and state anxiety during the acute crisis than women with weaker self-concepts and less social support. It was further predicted that self-concept would be more critical than social support due to the acute nature of the event. Finally, self-concept was predicted to be related to psychological distress both during the acute and everyday stress situations (a direct effect), while social support was predicted to be related to psychological distress only during the acute stress situation (a buffering effect). The hypotheses were generally confirmed. However, self-concept and social support were seen as complexly related to psychological distress during the acute phase, one not necessarily being more critical than the other. The selective employment of available resistance resources to fit the situation and implications for preventive intervention were discussed.     

The contributionof task-related factors to ERP repetition effects at short and long lags

Event-related potentials (ERPs) were used to assess the relative contribution of task-related decision-making processes to the repetition effect at Lags 0 and 15. Electrophysiological activity was recorded from 16 subjects in two tasks. Task A required a lexical decision: subjects were instructed to silently count infrequently occurring nonwords in a list of words and nonwords. Task B, a recognition memory task presented in four blocks, required subjects to distinguish between old and new probes in each block. Significant ERP repetition effects, equivalent in both tasks, were found at Lag 0. In contrast, at Lag 15, the repetition effect was significant only in Task A. These results suggest that ERPs are sensitive primarily to poststimulus-identification sources of the repetition effect, such as the recovery of episodic traces related to stimulus-categorization and decision-making processes.     

Personality, Mythology and Religion

This paper contrasts Judaism and Hellenism with regard to two opposing personality types: the “participant” and the “separant.” “Participant” means the identification of the ego with people, objects or symbols outside the self, and the desire to have one's separate identity in fusion with these externals. “Separation” implies the opposite. Hellinism is identified with the separate Sisyphean culture, and Judaism with the participant Tantalic culture.     

Dichotic sequence discrimination: The effect of continued practice

Summary Dichotic sequence discrimination was studied by means of a three-alternative forced-choice method. Two of the alternatives (same) consisted of a single pair of dichotic clicks with the stimulus at one ear preceding the stimulus at the other ear by a given temporal separation (e.g., R-t-L). One of the alternatives consisted of a single pair of clicks with the opposite sequence (e.g., L-t-R). The subjects' task was to discriminate between the different and the same dichotic pairs. The results indicate that discrimination is a nonmonotonic function of t, i.e., V- or U-shaped, with high levels at both short and long temporal separations (t=2 and 4 ms and t=64 and 96 ms) and with lower levels of discrimination for intermediate ts. A second experiment was performed to study the effect of continued practice by subjects trained in dichotic sequence discrimination for ts 4 and 64 ms (high discrimination levels) and for t=16 ms (low discrimination level). There was no systematic trend towards improvement over 8 blocks of 50 trials for each t. Discrimination levels of these ts did not differ between Experiments 1 and 2.Dr. Babkoff is spending the 1979–1981 academic year at the Walter Reed Army Institute of Research, Department of Military Medical Psychophysiology, Forest Glen Annex, Building 189, Washington, D.C. 20012, USAThe experiments were conducted at the Bar-Ilan University, Ramat-Gan, Israel.

Priming visual face-processing mechanisms: electrophysiological evidence

Accumulated evidence from electrophysiology and neuroimaging suggests that face perception involves extrastriate visual mechanisms specialized in processing physiognomic features and building a perceptual representation that is categorically distinct and can be identified by face-recognition units. In the present experiment, we recorded event-related brain potentials in order to explore possible contextual influences on the activity of this perceptual mechanism. Subjects were first exposed to pairs of small shapes, which did not elicit any face-specific brain activity. The same stimuli, however, elicited face-specific brain activity after subjects saw them embedded in schematic faces, which probably primed the subjects to interpret the shapes as schematic eyes. No face-specific activity was observed when objects rather than faces were used to form the context. We conclude that the activity of face-specific extrastriate perceptual mechanisms can be modulated by contextual constraints that determine the significance of the visual input.     

Treatment for sexually abused children and adolescents

The authors review research demonstrating the variable effects of childhood sexual abuse, the need for intervention, and the effectiveness of available treatment models. The well-controlled treatment-outcome studies reviewed do not focus on sensationalistic fringe treatments that treat sexually abused children as a special class of patients. Instead, studies demonstrate empirical evidence for extending and modifying treatment models from mainstream clinical child psychology to sexually abused children. The authors propose a continuum of interventions to meet the needs of this heterogeneous group. Interventions range from psychoeducation and screening, to short-term, abuse-focused cognitive-behavioral therapy with family involvement, to more comprehensive long-term plans for multiproblem cases. Last discussed are gaps in the research and suggestions for future research to address the pressing dilemmas faced by clinicians and policymakers.     

Semantic categorization in the human brain: spatiotemporal dynamics revealed by magnetoencephalography

We examined the cortical representation of semantic categorization using magnetic source imaging in a task that revealed both dissociations among superordinate categories and associations among different base-level concepts within these categories. Around 200 ms after stimulus onset, the spatiotemporal correlation of brain activity elicited by base-level concepts was greater within than across superordinate categories in the right temporal lobe. Unsupervised clustering of data showed similar categorization between 210 and 450 ms mainly in the left hemisphere. This pattern suggests that well-defined semantic categories are represented in spatially distinct, macroscopically separable neural networks, independent of physical stimulus properties. In contrast, a broader, task-required categorization (natural/man-made) was not evident in our data. The perceptual dynamics of the categorization process is initially evident in the extrastriate areas of the right hemisphere; this activation is followed by higher-level activity along the ventral processing stream, implicating primarily the left temporal lobe.     

Personal Growth and Meaning in Life Among First-Time Mothers and Grandmothers

This cross-sectional study examined personal growth and meaning in life among mothers and grandmothers who recently went through major transitions in a woman’s life. It investigated the contribution of the internal resources of perception of self (self-esteem) and perceived characteristics of the situation (cognitive appraisal of threat, challenge, and self-efficacy) and the external resource of perceived social support, as well as two background variables: age, and frequency of meetings between mothers and grandmothers. Participants were 152 first-time mothers 6–24?months after delivery, and their own mothers who were first-time grandmothers (n?=?152). The results showed differential contributions to meaning in life and personal growth in the two generations, indicating that the proposed variables can indeed explain growth and meaning in life in these life stages. They reveal not only the similarities and differences between the response of mothers and grandmothers to these parallel life transitions, but also how information about one generation may help explain the response of the other. The different patterns of associations which emerged for growth and meaning in life are also discussed.

Association and dissociation between detection and discrimination of objects of expertise: Evidence from visual search

Expertise in face recognition is characterized by high proficiency in distinguishing between individual faces. However, faces also enjoy an advantage at the early stage of basic-level detection, as demonstrated by efficient visual search for faces among nonface objects. In the present study, we asked (1) whether the face advantage in detection is a unique signature of face expertise, or whether it generalizes to other objects of expertise, and (2) whether expertise in face detection is intrinsically linked to expertise in face individuation. We compared how groups with varying degrees of object and face expertise (typical adults, developmental prosopagnosics [DP], and car experts) search for objects within and outside their domains of expertise (faces, cars, airplanes, and butterflies) among a variable set of object distractors. Across all three groups, search efficiency (indexed by reaction time slopes) was higher for faces and airplanes than for cars and butterflies. Notably, the search slope for car targets was considerably shallower in the car experts than in nonexperts. Although the mean face slope was slightly steeper among the DPs than in the other two groups, most of the DPs’ search slopes were well within the normative range. This pattern of results suggests that expertise in object detection is indeed associated with expertise at the subordinate level, that it is not specific to faces, and that the two types of expertise are distinct facilities. We discuss the potential role of experience in bridging between low-level discriminative features and high-level naturalistic categories.
