Disembodiment in online social interaction: impact of online chat on social support and psychosocial well-being.

This study investigates how disembodiment--that is, transcendence of body constraints in cyberspace--in online chat affects social psychological well-being. The results demonstrate that disembodiment is a strong predictor of increased loneliness and depression, and decreased social support. However, the amount of chat use is a positive contributor to decreased offline estrangement and depression, and increased happiness. These contrasting results suggest that online chat use is a technology for social connection used for offline connectivity, but the disembodiment motive is associated with declines in social support and psychosocial well-being. The investigation of specified motives for online interaction, personal competency, or advanced technological alternatives in interaction is suggested for future research on the effects of online interaction on offline outcomes.     

Transfer of orthogonal stimulus-response mappings to an orthogonal Simon task

When up-down stimulus locations are mapped to left-right keypresses, an overall advantage for the up-right/down-left mapping is often obtained that varies as a function of response eccentricity. This orthogonal stimulus-response compatibility (SRC) effect also occurs when stimulus location is irrelevant, a phenomenon called the orthogonal Simon effect, and has been attributed to correspondence of stimulus and response code polarities. The Simon effect for horizontal stimulus-response (S-R) arrangements has been shown to be affected by short-term S-R associations established through the mapping used for a prior SRC task in which stimulus location was relevant. We examined whether such associations also transfer between orthogonal SRC and Simon tasks and whether correspondence of code polarities continues to contribute to performance in the Simon task. In Experiment 1, the orthogonal Simon effect was larger after practising with an up-right/down-left mapping of visual stimuli to responses than with the alternative mapping, for which the orthogonal Simon effect tended to reverse. Experiment 2 showed similar results when practice was with high (up) and low (down) pitch tones, though the influence of practice mapping was not as large as that in Experiment 1, implying that the short-term S-R associations acquired in practice are at least in part not modality specific. In Experiment 3, response eccentricity and practice mapping were shown to have separate influences on the orthogonal Simon effect, as expected if both code polarity and acquired S-R associations contribute to performance.     

Changes in brain activation induced by the training of hypothesis generation skills: an fMRI study

The aim of the present study is to investigate the learning-related changes in brain activation induced by the training of hypothesis generation skills regarding biological phenomena. Eighteen undergraduate participants were scanned twice with functional magnetic resonance imaging (fMRI) before and after training over a period of 2 months. The experimental group underwent eight biological hypothesis generation training programs, but the control group was not given any during the 2-month period. The results showed that the left frontal gyri, the cingulate gyrus, and the cuneus were activated during hypothesis generation. In addition, the brain activation of the trained group increased in the left inferior and the superior frontal gyri, which are related to working memory load and higher-order inferential processes. However, the activation after training decreased in the occipito-parietal route, which is associated with the perception and the analysis processes of visual information. Furthermore, the results have suggested that the dorsolateral prefrontal cortex (DLPFC) region is the critical area in the training of hypothesis generation skills.     

Impaired body but not face perception in patients with obsessive–compulsive disorder

Background. Empirical evidence involving the processing of social information by patients with obsessive–compulsive disorder (OCD) has been relatively scarce. Our study investigated the perceptual abilities of patients with OCD to recognize human faces and bodies. Method. Fifty‐four drug‐free or drug‐naïve patients with OCD and 42 healthy controls performed discrimination tasks consisting of four types of stimuli: two sets of faces that were manipulated with regard to configuration and features, human bodies, and chairs. The stimuli were presented in upright and upside‐down orientations. Results. Patients with OCD were significantly less accurate in discriminating pairs of bodily postures implying actions. However, we found no significant differences between patient and control groups in the ability to recognize faces and chairs. The inversion effects for bodies and faces were also comparable between the two groups. Conclusions. The current findings suggest that patients with OCD experience difficulty in perceiving static forms of bodily postures, but are able to adequately recognize human faces. Our data indicate a selective deficit in the perception of bodily postures in those with OCD and suggest that this deficit is probably not related to the abnormal configurational processing of social objects.     

Codependence and Interdependence: Cross-Cultural Reappraisal of Boundaries and Relationality

This article explores the cross-cultural implications of the Western notion of boundaries and the Asian matrix of relationality for pastoral care ministry. Theorists of codependence (relationship addiction) show that American awareness of boundaries produces phobic attitudes toward the interwoven interplay of human relationships. Noting the underlying American cultural ideal (i.e., individual autonomy), evidences that boundaries are culturally defined are reviewed. Drawing upon the social-psychological concept of interdependence (Asian construal of self), the author proposes that there is a need for a different understanding of boundaries, since some Asian people have strikingly different construals of the self, of others, and of the interdependence of the two. Boundaries and relationality need to be in dialogue with each other so as to create relational boundaries that empower mutual relations within which we may come to experience the power of the relational, triune God.     

Perceived emotion suppression and culture: Effects on psychological well‐being

Whether the negative effects of emotion suppression on psychological well‐being are applicable cross‐culturally is a long‐debated topic. The present study attempted to shed light on this debate, focusing on the effects of perceived emotion suppression and examining the psychological processes leading from perceived emotion suppression to lower psychological well‐being. We used a scale manipulation to lead 196 American and 213 Chinese participants to perceive themselves as having suppressed their emotions to a greater or lesser extent and then measured their life satisfaction. As expected, both the American and Chinese participants reported lower life satisfaction in the high‐suppression condition than in the low‐suppression condition; this negative effect was mediated by positive affect and moderated by self‐esteem. Specifically, perceived high emotion suppression decreased positive affect, which in turn led to lower well‐being. This effect was observed only for those with low self‐esteem, but the patterns and mechanisms were consistent cross‐culturally.     

Unilateral concessions from the other party: concession behavior, attributions, and negotiation judgments

This article examines the effects of the other party's concession behavior on a negotiator's satisfaction and judgments. The timing of the concessions (immediate, gradual, delayed) and the justifications provided by the other party (negotiator skill vs. external constraints) were manipulated using a scenario method (Study 1) and a role-playing experiment (Study 2). Study 1 showed that concession timing influenced valuation of the object and satisfaction with the partner and the outcome. Justifications about why the concession was made interacted with concession timing to influence participants' attributions. Participants' attributions for why the concession was actually made, in turn, had a main effect on satisfaction and judgments of the negotiation. Study 2 replicated some, but not all, of these findings.     

Influences of multiple spatial stimulus and response codes on orthogonal stimulus-response compatibility

When up-down stimuli are mapped to left-right responses, an up-right/down-left mapping advantage is found that is modified by response eccentricity and hand posture. These effects can be attributed to correspondence of asymmetric stimulus and response codes formed relative to multiple reference frames. We examined the influence of stimulus-set location on these orthogonal stimulus-response compatibility (SRC) effects. In Experiment 1, the stimulus set appeared in the upper or lower display positions. A spatial code for stimulus-set location was formed, producing Simon-type response eccentricity and hand posture effects, but this code had no influence on the coding of the relevant stimuli. In Experiment 2, the stimulus set appeared in the left, center, or right positions relative to the response location, which also varied, to dissociate the effects of response location, relative to the stimulus display and body midline. The former factor influenced the orthogonal SRC effect for both unimanual switch movements and bimanual keypresses, and the latter factor influenced the effect for only unimanual switch movements. Stimulus-set location causes orthogonal Simon-type effects when varied along the stimulus dimension and provides a referent for response coding when varied along the response dimension.     

Stimulus-set location does not affect orthogonal stimulus-response compatibility

In two-choice tasks for which stimuli and responses vary along orthogonal dimensions, one stimulus-response mapping typically yields better performance than another. For unimanual movement responses, the hand used to respond, hand posture (prone or supine), and response eccentricity influence this orthogonal stimulus-response compatibility (SRC) effect. All accounts of these phenomena attribute them to response-related processes. Two experiments examined whether manipulation of stimulus-set position along the dimension on which the stimuli varied influences orthogonal SRC in a manner similar to the way that response location does. The experiments differed in whether the stimulus dimension was vertical and the response dimension horizontal, or vice versa. In both experiments, an advantage of mapping up with right and down with left was evident for several response modes, and stimulus-set position had no influence on the orthogonal SRC effect. The lack of effect of stimulus-set position is in agreement with the emphasis that present accounts place on response-related processes. We favor a multiple asymmetric codes account, for which the present findings imply that the polarity of stimulus codes does not vary across task contexts although the polarity of response codes does.     

New developments in electroconvulsive therapy and magnetic seizure therapy

New findings regarding the mechanisms of action of electro-convulsive therapy (ECT) have led to novel developments in treatment technique to further improve this highly effective treatment for major depression. These new approaches include novel placements, optimization of electrical stimulus parameters, and new methods for inducing more targeted seizures(eg, magnetic seizure therapy [MST]). MST is the use of transcranial magnetic stimulation to induce a seizure. Magnetic fields pass through tissue unimpeded, providing more control over the site and extent of stimulation than can be achieved with ECT. This enhanced control represents a means of focusing the treatment on target cortical structures thought to be essential to antidepressant response and reducing spread to medial temporal regions implicated in the cognitive side effects of ECT. MST is at an early stage of development. Preliminary results suggest that MST may have some advantages over ECT in terms of subjective side effects and acute cognitive functioning. Studies designed to address the antidepressant efficacy of MST are underway. As with all attempts to improve convulsive therapy technique, the clinical value of MST will need to be established through controlled clinical trials. This article reviews the experience to date with MST, and places this work in the broader context of other means of optimizing convulsive therapy in the treatment of depression.
