The Impact of Rejection Sensitivity on Self-Disclosure Within the Context of Online Dating.

Prior research suggests that rejection sensitive individuals may find it easier to express their true selves in an online environment. The purpose of the present study was to examine the extent to which rejection sensitivity (RS) and true self influence self-disclosure within the context of online dating. We collected data from a total of 1,295 individuals who completed an online survey. For those who engaged in online dating, RS was not directly related to self-disclosure in online dating profiles or in communicating with individuals met through online dating sites/apps, but true self was. In addition, there was an indirect relationship between RS and self-disclosure in the context of online dating through true self. These findings suggest that rejection sensitive individuals who feel more comfortable revealing aspects of their "true" selves online may be more likely to engage in self-disclosure within the context of online dating, which could potentially offer some clue as to why rejection sensitive individuals may be somewhat more likely to engage in online dating than less rejection sensitive individuals. That is, rejection sensitive individuals are perhaps more likely to engage in online dating because it may facilitate representation of their "true" selves and may thus increase dating success.

Assessing the adequacy of postexperimental inquiries in deception research and the factors that promote participant honesty.

The primary aim of this research was to assess the adequacy of postexperimental inquiries (PEI) used in deception research, as well as to examine whether mood state, reward, or administering the PEI as a face-to-face interview or computer survey impacts participants' willingness to divulge suspicion or knowledge about a study. We also sought to determine why participants are not always forthcoming on the PEI. Study 1 examined how frequently PEIs are included in research and found that most researchers employing deception do use a PEI. Studies 2 and 3 showed that participants are often unwilling to divulge suspicion or awareness of deception or to admit to having prior knowledge about a study, though offering a reward and completing the PEI on a computer modestly improved awareness and admission rates. Study 4 indicated several reasons why participants may not reveal suspicion or knowledge about a study on the PEI.

Rejection elicits emotional reactions but neither causes immediate distress nor lowers self-esteem: a meta-analytic review of 192 studies on social exclusion.

Competing predictions about the effect of social exclusion were tested by meta-analyzing findings from studies of interpersonal rejection, ostracism, and similar procedures. Rejection appears to cause a significant shift toward a more negative emotional state. Typically, however, the result was an emotionally neutral state marked by low levels of both positive and negative affect. Acceptance caused a slight increase in positive mood and a moderate increase in self-esteem. Self-esteem among rejected persons was no different from neutral controls. These findings are discussed in terms of belongingness motivation, sociometer theory, affective numbing, and self-esteem defenses.

Salivary cortisol in response to acute social rejection and acceptance by peers.

Past research indicates that social rejection predicts a wide range of psychological problems (e.g., depression), but laboratory studies examining self-reports of negative affect after social rejection have reported inconsistent results. Salivary cortisol was measured before and after a social rejection/acceptance manipulation for objective assessment of psychological distress subsequent to peer rejection. Rejected participants were predicted to show significantly greater salivary cortisol than accepted or control participants. The present research also examined several factors that may moderate the relationship between acute rejection and cortisol. As predicted, rejected participants exhibited significantly higher cortisol than accepted or control participants. Defensiveness moderated the relationship between rejection and cortisol; highly defensive rejected participants showed significantly lower cortisol than less defensive rejected participants after peer rejection. Results indicate that social rejection causes psychological distress, but highly defensive individuals appear to be less susceptible than less defensive individuals to increases in salivary cortisol after acute social rejection.

Anterior EEG asymmetries and opponent process theory.

The opponent process theory of emotion [Solomon, R.L., and Corbit, J.D. (1974). An opponent-process theory of motivation: I. Temporal dynamics of affect. Psychological Review, 81, 119-143.] predicts a temporary reversal of emotional valence during the recovery from emotional stimulation. We hypothesized that this affective contrast would be apparent in asymmetrical activity patterns in the frontal lobes, and would be more apparent for left frontally active individuals. The present study tested this prediction by examining EEG asymmetries during and after blocked presentations of aversive pictures selected from the International Affective Picture System (IAPS). 12 neutral images, 12 aversive images, and 24 neutral images were presented in blocks. Participants who were right frontally active at baseline did not show changes in EEG asymmetry while viewing aversive slides or after cessation. Participants left frontally active at baseline, however, exhibited greater relative left frontal activity after aversive stimulation than before stimulation. Asymmetrical activity patterns in the frontal lobes may relate to affect regulatory processes, including contrasting opponent after-reactions to aversive stimuli.

Can EEG asymmetry patterns predict future development of anxiety and depression? A preliminary study.

Previous research has shown that those reporting symptoms of depression and anxiety tend to exhibit greater relative right frontal electroencephalographic (EEG) activity. Thus, Davidson [Davidson, R.J., 1995. Cerebral asymmetry, emotion, and affective style. In: Davidson, R.J., Hugdahl, K. (Eds.), Brain Asymmetry. MIT, Cambridge, pp. 361-387] has suggested that greater relative right anterior activity may act as a vulnerability marker for the development of depression and anxiety disorders. This study therefore examined whether anterior and posterior EEG asymmetry patterns predicted anxiety and depressive symptoms one year later. At time 1, participants completed the Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) and had baseline EEG activity recorded. Participants then completed the BDI and STAI one year later. Those with relatively greater EEG activity in the right anterior region reported greater trait anxiety one year later. These preliminary results suggest that relative right frontal EEG activity may predict future development of anxiety symptoms.

Relative left-frontal activity is associated with increased depression in high reassurance-seekers.

Excessive reassurance-seeking, which has been associated with depression in many studies, can be defined as the relatively stable tendency to seek assurance perseveratively from others. We hypothesized that although depression has been associated with left-frontal EEG hypoactivity, reassurance-seekers may possess a unique diathesis that is more likely to be associated with increased left-frontal activity. Data were collected from 12 volunteers who were receiving therapeutic services from a University Clinic. EEG asymmetry scores were averaged over two measurement occasions at least 3 weeks apart. As predicted, stable relative right-frontal activity was associated with increased depression in those who were low on reassurance-seeking, while stable relative left-frontal activity was associated with increased depression among high reassurance-seekers. Perhaps those who seek reassurance excessively do so because of their inability to alter their behavior even when environmental cues are no longer reinforcing, which can maintain or exacerbate their depressive symptoms.
