Negative support of significant others affects psychological adjustment in breast cancer patients

Significant others play an important role in providing support in patients' lives, but some types of support negatively affect the patients. This study was conducted in early-stage breast cancer patients to examine the structure of support, which was provided by their significant others and assessed negatively by the patients, and to identify negative support relating to the psychological adjustment of these patients. Thus, we first conducted interviews among 28 breast cancer patients to identify these support items assessed as negative; next, we conducted a questionnaire survey using the resulting items in 109 postoperative patients who had early-stage breast cancer. We performed exploratory and confirmatory factor analyses and obtained a valid second-order factor structure, including superordinate factors (excessive engagement, avoidance of problems and underestimation) and subordinate factors (overprotection, encouragement and management). Among these factors, the avoidance of problems was the only factor to be negatively associated with psychological adjustment of the patients, suggesting that these patients receive problem-avoiding support. The results of our study suggest that such problem-avoiding support from significant others can be counter-productive and potentially worsen the psychological adjustment of breast cancer patients.     

Self-Construal,Social Support,and Loneliness in Japan

We examine the effects of self-construal and social support in friendships on loneliness using data from a random sample of residents in Tokyo, Japan. We find that the relationship between interdependent and independent self-construal is not orthogonal, as found by studies in the West, but moderately positive. Net of independence, interdependence significantly and positively predicts perceived social support, but not vice versa. By comparison, neither interdependence nor independence completely absorbs the protective effect of the other on loneliness. Our full models including other variables (e.g. gender, age, and extraversion personality) show that interdependence matters more in explaining perceived social support and loneliness. Moreover, perceived social support partially mediates the negative effect of interdependence on loneliness. We discuss implications of these and other related findings for future research on self-construal and subjective wellbeing across societies.

     

An Examination of the Effects of Stress Management Training for Japanese College Students of Social Work

The purpose of the present study was to examine the effects of a stress-management program for college students of social work on their perception of mental stress and stress-coping strategies. Students in a stress-management group received progressive muscle training, cognitive-behavioral skills training, and assertion training for 14 weeks. Their life events, stress symptoms, and stress-coping skills (active and passive coping skills), evaluated on the first and last days of program, were compared with those of a control group. The effect of the participants' trait anxiety on those variables was also examined. Because the stress-management program in the present study focused on coping strategies, it was expected that the students' coping skills would change. The results showed that passive coping skills of students in the stress-management group had decreased after the program.     

Matching vocalizations to vocalizing faces in a chimpanzee (<Emphasis Type="Italic">Pan troglodytes</Emphasis>)

Auditory–visual processing of species-specific vocalizations was investigated in a female chimpanzee named Pan. The basic task was auditory–visual matching-to-sample, where Pan was required to choose the vocalizer from two test movies in response to a chimpanzees vocalization. In experiment 1, movies of vocalizing and silent faces were paired as the test movies. The results revealed that Pan recognized the status of other chimpanzees whether they vocalized or not. In experiment 2, two different types of vocalizing faces of an identical individual were prepared as the test movies. Pan recognized the correspondence between vocalization types and faces. These results suggested that chimpanzees possess crossmodal representations of their vocalizations, as do humans. Together with the ability of vocal individual recognition, this ability might reflect chimpanzees profound understanding of the status of other individuals.     

Comparison between the lambda response of eye-fixation-related potentials and the P100 component of pattern-reversal visual evoked potentials

The purpose of this study was to compare the lambda response of eye-fixation-related potentials (EFRPs) with the P100 component of pattern-reversal visual-evoked potentials. EFRPs were obtained by averaging EEGs time-locked to the offset of the saccade. The dipole of the lambda response and that of the P100 component were estimated by the dipole-tracing method (Musha & Homma, 1990). The locations of their dipoles at the occipital sites were very close to each other when the difference waveform, which was calculated by subtracting the EFRP to the patternless stimulus from the EFRP to the patterned stimulus, was used for the lambda response. This finding implies that the lambda response and P100 have a common neural generator in the visual cortex. However, the peak latency of the lambda response was shorter than that of P100. The saccades in the EFRP trial were considered to be the cause of the difference.     

Comparison of blinking behavior during listening to and speaking in Japanese and English

Blinking behavior during conversation may be different between conditions in listening and responding to questions because sifting attention from external to internal is possibly associated. The purpose of this study was to compare blinking behavior, duration, heart rates, and mental states during the tasks of listening to and responding to questions in Japanese and English. Participants were 67 (35 men and 32 women) undergraduate students. Blink rate while responding to questions in English did not differ from that while responding to questions in Japanese, but blink rate while listening to questions in English was significantly reduced compared to that while listening to Japanese. While anxiety and uneasiness were increased by the English conversation, blink rate and heart rate were decreased. Blinking behavior may be related to thinking and attention.     

Loneliness and inducing incremental theories of social interactions to produce adaptive change

College students (n = 388) participated in a two‐part online study (a survey and an experiment) examining the role of implicit theories in the experience of loneliness. Survey results revealed that lonely people tend to endorse entity theories of social competence and friendship. Experimental results showed that inducing an incremental theory of social competence reduced communication apprehension and increased social engagement among individuals regardless of their levels of loneliness. Inducing an incremental theory of friendship increased social engagement but did not influence the level of communication apprehension or social avoidance. Overall, the results suggest that an incremental theory of social interactions can reduce thoughts that are not conducive to fostering social connections among people in general, including lonely ones.     

Mirror reversal: empirical tests of competing accounts

In a mirror, left and right are said to look reversed. Surprisingly, this very familiar phenomenon, mirror reversal, has still no agreed-upon account to date. This study compared a variety of accounts in the light of empirical data. In Experiment 1, 102 students judged whether the mirror image of a person or a character looked reversed or not in 15 settings and also judged the directional relation between its components. In Experiment 2, 52 students made the reversal judgements in 13 settings. It was found for the first time that a substantial proportion of people denied the left-right mirror reversal of a person, whereas virtually all of them did recognize that of a character. This discrepancy strongly suggested that these two kinds of mirror reversal are produced by different processes, respectively. A number of findings including this discrepancy clearly contradicted two accounts that are currently active: the one based on the priority of the up-down and front-back axes over the left-right axis, and the one based on the physical rotation of an object. All the findings were consistent with an account that considered mirror reversal a complex of three different phenomena produced by three different processes, respectively.     

Children's response biases to results of object sharing

This study investigated whether 2- to 6-year-old children exhibit a response bias to questions pertaining to the results of sharing objects that should attract their interest. An experimenter distributed four objects between herself/himself and a child, equally or unequally (more to the child or more to the experimenter) and asked the child yes-no questions: “Is this okay?” and “Is this bad?” The results indicated that 2- and 3-year-olds exhibited a yes bias in all conditions, 4-year-olds exhibited a yes bias to the equal condition and to the unequal condition with more distributed to the child, and 5-year-olds exhibited a yes bias to both unequal conditions, whereas 6-year-olds did not show any response bias. Young preschoolers exhibited a yes bias regardless of questions and children may become able to say both “yes” and “no” appropriately to questions about object sharing after the age of six.
